Is your baby teething?
Find out what to expect as your baby
approaches the solid food frontier.
Your baby’s teething timeline could begin as early as three or four months old, and last through toddlerhood. By age three, all 20 primary teeth should have managed to emerge from your toddler’s gums. There are several stages of teething to overcome before you and your baby reach the pearly white finish line. Here are some of the symptoms you can expect, and ways you can get through this experience together! If you have any questions or concerns, be sure to talk to your pediatrician.
How to tell if your baby is teething
She’s a drooling machine
You might notice your teething baby drooling more than usual, which could result in a small facial rash. Fear not! Your pediatrician can suggest some options to help moisturize your baby’s face.
He’s chewing on EVERYTHING
Don’t be alarmed if your baby appears to have a newfound interest in putting things in his mouth. Chewing on hard objects, toys, or teething rings can help teething babies relieve painful pressure from their gums.
She’s fussier than usual
You’d cry too if you had tiny teeth trying to break through your gums! Gently rub your baby’s gums with a clean finger, or firm rubber pacifier to help take some pressure off.
He has a slight fever
As long as it doesn’t break 101°F, a teething fever is totally normal. Call your pediatrician if your baby experiences a high fever or diarrhea.
Infants’ TYLENOL® works differently than other pain and fever medicines to relieve your teething toddler’s pain, while staying gentle on the tummy. If your child is under 2 years of age, be sure to ask your doctor before giving your child Infants' Tylenol®.
*If you have any questions, talk to your pediatrician.

Excerpts from: Slavery and the Jews A Historical Inquiry By Eli Faber "Eli Faber is professor of History at John Jay College of Criminal Justice of The City University of New York....This Sonia Kroland Coster Memorial Lecture was delivered at Hunter College on May 11, 1994." "The Portugese dominated the slave trade throughout the 1500s, remaining in control of it until at least 1625." (Faber, 1) "The Portugese were responsible for transporting two-fifths, or approximately 4,190,000, of all slaves exported from Africa to the Americas." (Ibid, 2) "As part of their ascent during the 1600s to economic primacy in Europe, going to war first against Portugul and then against England, the Dutch also sought to establish as much control as possible over the slave trade. From 1640 until 1700, they may have ranked second in the slave trade behind Portugul, and they remained active during the 1700s after the English had surpassed them." (Ibid.) "During the succeeding century, England surged ahead and became Europe's largest slave-transporting nation. Between 1730 and 1807, Britain shipped almost 2,463,000 slaves to the western hemisphere, 41.7 percent of all slaves conveyed to the New World during the eighteenth century. This enormous enterprise was the work or merchants who resided primarily in three ports: London, Bristol, and Liverpool. "The majority of England's slave exports to her own colonies were carried to Barbados, Jamaica, and her other islands in the Caribbean. The thirteen American colonies received only 21.6 percent. Indeed, the American colonies and their successor, the United States of America, accounted for six to seven percent of the entire slave trade, or 715,000 of the more than 11 million people shipped from Africa to the western hemisphere between 1510 and 1840, when the transatlantic traffic in human beings finally ended. "During the course of the period between 1510 and 1840, Jewish merchants participated in the transport and sale of slaves, and Jewish inhabitants of the western hemisphere owned slaves." (Ibid, 3) "Not only have Jewish historians long known about such activities, but they have written about them, well before the current flurry of interest in Jewish participation in Slavery. A few examples should suffice. "Historian Herbert Bloom, in his 1937 study of economic activity among the Jews of Amsterdam during the 1600s and 1700s, wrote of Jews who owned slaves in South Africa, Brazil, and Surinam. He also noted the attempts made by some Jews to transport slaves to Spain's colonies in defiance of the Durtch West India Company's right to monopolize the slave trade.
" (Ibid., 3-4) [Other examples include Jacob Rader Marcus, Rabbi Bertram Korn, Isaac Emmanuel and Johathan Israel.] "Because of these publications - which by no means exhaust the possible examples - one could never claim that Jewish historians have either neglected or denied the presence of Jewish merchants in the slave trade, or consigned to oblivion the fact that some Jews owned slaves." (Ibid. 4-5) "Non-Europeans, too, were involved. Long before the Portugese enmeshed themselves in the enslavement of Africans, Arab traders penetrated deeply into the African continent, procuring men, women, and children whom they transported to North Africa and the Middle East. The Arab trade began as long ago as the ninth century and lasted into the nineteenth, continuing after the transatlantic trade to the New World ceased. "Africans also played a role, because European slave traders were not permitted to penetrate into the African continent but were required, instead, to purchase slaves from Africans who brought them in caravans to the coasts." (Ibid. 5) "If there is any surprise involved in slavery, it is most likely to arise upon learning that many eighteenth-century Quakers owned slaves and actively engaged in slave trading.... What ought to be emphasized, however, is that some Quakers participated in slavery, while others struggled to end it." (Ibid.) "Scholars reject any tendency to characterize all the members of any one group as the primary culprits in the international commerce system that evolved after the European discovery of the New World. Thus, just as some Quakers, some Arabs, some Africans, some Portugese, and some Frenchmen were involved in the instituti

Applied scientists led by Caltech's Kerry Vahala have discovered a new type of optical soliton wave that travels in the wake of other soliton waves, hitching a ride on and feeding off of the energy of the other wave.
Solitons are localized waves that act like particles: as they travel across space, they hold their shape and form rather than dispersing as other waves do.
They were first discovered in 1834 when Scottish engineer John Scott Russell noted an unusual wave that formed after the sudden stop of a barge in the Union Canal that runs between Falkirk and Edinburgh. Russell tracked the resulting wave for one or two miles, and noted that it preserved its shape as it traveled, until he ultimately lost sight of it.
He dubbed his discovery a "wave of translation." By the end of the century, the phenomenon had been described mathematically, ultimately giving birth to the concept of the soliton wave. Under normal conditions, waves tend to dissipate as they travel through space. Toss a stone into a pond, and the ripples will slowly die down as they spread out away from the point of impact. Solitons, on the other hand, do not.
In addition to water waves, solitons can occur as light waves. Vahala's team studies light solitons by having them recirculate indefinitely in micrometer-scale circular circuits called optical microcavities. Solitons have applications in the creation of highly accurate optical clocks, and can be used in microwave oscillators that are used for navigation and radar systems, among other things.
But despite decades of study, a soliton has never been observed behaving in a dependent -- almost parasitic--manner.
"This new soliton rides along with another soliton -- essentially, in the other soliton's wake. It also syphons energy off of the other soliton so that it is self-sustaining. It can eventually grow larger than its host," says Vahala, Ted and Ginger Jenkins Professor of Information Science and Technology and Applied Physics and executive officer for applied physics and materials science in the Division of Engineering and Applied Science.
Vahala likens these newly discovered solitons to pilot fish, carnivorous tropical fish that swim next to a shark so they can pick up scraps from the shark's meals. And by swimming in the shark's wake, the pilot fish reduce the drag of water on their own body, so they can travel with less effort.
Vahala is the corresponding author of a paper in the journal Nature Physics announcing and describing the new type of soliton, dubbed the "Stokes soliton." (The name "Stokes" was chosen for technical reasons having to do with how the soliton syphons energy from the host.) The new soliton was first observed by Caltech graduate students Qi-Fan Yang and Xu Yi. Because of the soliton's ability to closely match the position and shape of the original soliton, Yang's and Yi's initial reaction to the wave was to suspect that laboratory instrumentation was malfunctioning.
"We confirmed that the signal was not an artifact of the instrumentation by observing the signal on two spectrometers. We then knew it was real and had to figure out why a new soliton would spontaneously appear like this," Yang says.
The microcavities that Vahala and his team use include a laser input that provides the solitons with energy. This energy cannot be directly absorbed by the Stokes soliton -- the "pilot fish." Instead, the energy is consumed by the "shark" soliton. But then, Vahala and his team found, the energy is pulled away by the pilot fish soliton, which grows in size while the other soliton shrinks.
"Once we understood the environment required to sustain the new soliton, it actually became possible to design the microcavities to guarantee their formation and even their properties like wavelength -- effectively, color," Yi says. Yi and Yang collaborated with graduate student Ki Youl Yang on the research.
This work is described in a paper titled "Stokes solitons in optical microcavities," published on Sept. 5. The paper can be found online at http://www.

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...

Sunglasses for Children
Think only grown-ups need high-quality sunglasses? Think again.
Too much sun can significantly increase a person’s risk of cataracts, macular degeneration and other eye problems later in life. This risk depends on one’s cumulative exposure to sunlight over a lifetime. The best way to protect a person’s eyes from radiation damage is to begin dispensing high-quality sunglasses for children at an early age. This is true even if they don’t need prescription eyeglasses.
Children’s Eyes and UV
High-quality sunglasses are even more important for kids than they are for adults. Why? Children usually spend significantly more time outdoors than adults, increasing their exposure to ultraviolet (UV) and other solar radiation. According to the Skin Cancer Foundation, it is estimated that 23% of lifetime exposure to UV occurs by age 18. Other researchers say nearly half of a person’s lifetime UV exposure occurs by age 18.
Also, children have large pupils and the lens of a child’s eye does not filter UV and high-energy visible (HEV) light as effectively as an adult lens. These factors allow more harmful rays to penetrate deep into the eye during childhood. Unfortunately, many parents remain unaware of the importance of sunglasses for children. According to a 2012 Vision Council survey, 74 percent of American adults said they wear sunglasses for UV protection, but only 58 percent require their children to wear them. Read the full report here
Sunglasses for Kids: Recommended Features
100 Percent UV Protection
There are two types of ultraviolet rays from sunlight that can damage eyes: UVA and UVB. UVA is lower energy radiation, but it can penetrate deep into the eye. UVB has higher energy, but affects only the surface of the eye. For adequate eye protection, sunglasses for children should block 100 percent UVA and UVB.
Like UVA, high-energy visible (HEV) light can penetrate deep into the eye and increase the risk of retinal damage. HEV is also called “blue light” because it is composed of short-wavelength (380 to 500 nm) visible light that comprises the blue and violet end of the visible light spectrum. Brown or amber-colored sunglass tints usually block HEV light more effectively than other shades. Sunglasses for kids should block as much HEV as possible.
Generally, polycarbonate lenses are recommended for children’s sunglasses. These lenses automatically block 100 percent UV without the need for special lens coatings, tints or treatments.
“Poly” lenses also are lighter than regular plastic lenses and provide up to 10 times more impact resistance for greater comfort and eye safety during sports and active play.

While prevalence and types of risk factors for atherosclerosis (narrowing of the arteries due to fatty deposits) have varied over time from ancient times to modern society (such as levels of obesity, physical activity), genetic predisposition/risk for the condition today appears to be very similar to that in ancient times. This forms the subject of a paper in this month's edition of Global Heart (the journal of the World Heart Federation), written by Professor Albert Zink, Institute for Mummies and the Iceman, European Academy of Bolzano/Bozen (EURAC), Bolzano/Bozen, Italy, and colleagues.
While modern imaging techniques have been used to identify atherosclerosis in the mummified remains of multiple cultures, evidence of genetic predisposition has been harder to obtain due to the degradation of the genetic material over time. However, in a previous whole-genome study of the Tyrolean Iceman, a 5,300-year-old glacier mummy from the Alps, an increased risk for coronary heart disease was detected. The Iceman's genome revealed several single nucleotide polymorphisms (SNPs) that have been linked with modern day cardiovascular disease in the many genome-wide association studies that have been published across the past decade.
The remains of the Iceman have undergone extensive analysis, however for the purposes of this paper the most intriguing finding was that the Iceman showed a strong genetic predisposition for increased risk for coronary heart disease (CHD). This is of particular interest as the computed tomography (CT) scans of the Iceman already had revealed major calcification in several major blood vessels, including the carotid arteries, distal aorta, and right iliac artery, which are strong signs of generalised atherosclerotic disease. The authors say that other traditional cardiac risk factors, such as being overweight, tobacco smoking, lack of physical activity, and a high fat diet, can generally be ruled out in a person from this era.
In particular, the genetic sequencing data demonstrates that the Iceman had a very specific genetic mutation, namely that he was homozygous for the minor allele (GG) of rs10757274, located in chromosomal region 9p21. This SNP is currently regarded as being among the strongest genetic predictors of heart attacks and has been confirmed in several studies as a major risk locus for CHD.
Regarding the suggestion that our ancestors lived much purer and active lives, free from all risks of heart disease compared with modern day sedentary lifestyles, the authors say: "Wrong! Our ancestors going back thousands of years show signs of atherosclerosis, as suggested by modern research using CT to detect evidence of calcium deposits associated with atherosclerotic plaques in the arteries of mummies

Steadfast in cold winters, wind and drought, the white spruce (Picea glauca) grows 40 to 60 feet tall and 10 to 20 feet wide at maturity. Best suited for cold winter regions with cool summers, it makes a nice specimen tree, windbreak or linear hedgerow in USDA hardiness zones 2 through 5, perhaps in the colder parts of zone 6, as well. It does not cope with compacted soils or urban air and water pollution.
To develop into an uniform, well-branched and evenly-needled tree, locate a spot on your property where a white spruce receives at least eight hours of direct sunlight daily. Too much shading from nearby buildings or trees causes sparse branching and reduced foliage on twigs. White spruce's ideal soil conditions include an acidic to neutral soil pH (5.5 to 7.0) and a sandy or loamy soil rich in organic matter. The key is a well-draining soil that is not compacted or heavy. Clay or heavy loam soils need coarse bits of organic matter and grit incorporated for improved water drainage and porosity. Although drought tolerant, the white spruce grows better if the soil remains evenly moist across the growing season.
Plant a white spruce at least 5 to 10 feet away from shrubs and perennials in the garden so that when the spruce grows tall it is now overly crowded or shaded by nearby garden plants. Site the spruce at least 10 to 15 feet away from large, established shade trees or buildings. Planting a clustered grove of spruce trees creates a lush, dense matrix of branches edged in needles; shaded interior branches lose their needles but are rarely seen. For a cluster, plant trees 10 to 12 feet apart. To make an impenetrable windbreak or hedgerow, plant white spruce trees 8 to 15 feet apart. The closer the trees are planted, the more quickly their branches will grow into each other to block wind or views.
While container-grown spruce trees may be planted anytime of year when the soil is workable and not frozen, the best for planting is the very late summer or early autumn. Since white spruce grows in regions with very cold winters, gardeners in zones 2 through 4 should plant these trees in early spring to allow for as much new root growth as possible before the onset of winter.
Measure the size of the root ball of the white spruce. Dig the planting hole the same depth as the root ball, but two to three times as wide. Do not add soil amendments or fertilizers to the soil placed back around the tree once positioned in the planting hole. After the hole is filled, create a low berm around the tree to act as a catch basin for irrigation water. Keep the root ball of the planted tree well-watered for the first six months so that the soil remains moist, not soggy.

Pagan god Pan Vs. Jesus at Caesarea Philippi
Part I – Rock at Caesarea Philippi
Part IV - Pagan god Pan Vs Jesus
Caesarea Philippi was originally called Paneas because it was the center for the worship of the Greek god Pan. Today, the area is called Banias which is an Arabic variant of Paneas.
Stanley L. Jaki in his book AND ON THIS ROCK writes:
Pan’s cult … was a celebration of fertility. That the celebration readily took on forms of plain orgy is suggested by Pan’s most characteristic features: a head decorated with horns, a leery and lustful smile, and the prancing legs of a goat.
The name Pan, a contraction from Paon, gave origin to the word panic, which may have first referred to the stampeding of a herd. Its further meaning as human fright was a logical outgrowth of the unbridled lust that made Pan’s sanctuary first an alluring and then a frightening experience to many. [pages 24-28]
The niches carved out in the rock at Caesarea Philippi were for statues of their pagan gods. In Jesus’s time a person would have found a wooden statue of Pan in each of these niches. We can make many contrasts between the Pagan god of Pan and the One True God, Jesus Christ, who with the Father and the Holy Spirit make up our Triune God.
The Encyclopedia Encarta gives the following information on Pan.
“Pan (mythology), in Greek mythology, god of shepherds and flocks. He was believed to be responsible for their fertility. … Pan was especially fond of remote mountains and caves and was believed to be responsible for the sudden, inexplicable fear, or panic, …
In the 2nd century ad the Greek essayist Plutarch recorded that during the reign of Emperor Tiberius travelers sailing along the west coast of Greece heard a loud voice proclaiming the death of the great god Pan. In Christian legend, this story was associated with the Passion of Christ, which occurred during the reign of Tiberius, and was held to portend the victory of Christ over the pagan gods.”
While Pan was the Pagan god of shepherds, Jesus is the True Good Shepherd who lays down His life for His flock. John 10:1-14.
While Pan was considered the god of fertility by the pagans, Jesus is truly the “Author of Life,” Acts 3:15, and He gives everlasting life to those who follow Him. See John 11:20-26
Pan was considered responsible for panic and fear.
In the Book of Hebrew we read how Satan holds people in bondage through fear. Because of temptation a person often fears the pain that comes with dying to oneself in order to do God’s Will. And unfortunately we often choose sin thinking that it is the path of pleasure without suffering. Of course, when people do sin they inevitably bring about suffering at some point into their own lives and they often cause suffering in those closest to them. However, Jesus broke that bondage of sin and fear, so that by His grace we are enabled to die to our selfishness so that we might have new life in Jesus Christ.
Jesus’s death and Resurrection destroys Satan’s power over us which is the fear of death and the fear of dying to ourselves. This fear is represented by Golgotha, the Place of the Skull, and it was there that Jesus defeated Satan and ransomed us by paying the price of our sins. Golgotha is also called Calvary, since Calvary comes from the Latin word for “skull.” And right next to Calvary is the Resurrection Tomb.
While the translation above is more literal, some translators use “the jaws of death shall not prevail against it.”
Jesus’s defeat of Satan is the fulfillment of the prophecy in Genesis 3:15 which recorded that the Messiah would crush the head of the Serpent. See Separate Article on Genesis 3:15
The Jordan River has immense theological significance in both the Old and New Testaments. The water that flows from Caesarea Philippi forms one of the three sources of the Jordan River. By far, Caesarea Philippi is the most scenic. In a short distance downstream it forms into the waterfall and the swift stream that are pictured below.

A million dollars in cash (£640,000) awaits anyone who can develop a rigorous mathematical model for how fluids flow – this week's Millennium Prize Problem.
Fluids are extremely difficult to analyse because they can flow in such complicated ways. The next time you're bored in the kitchen, take a glass of water and let it stand until it's completely still (which takes longer than you might expect). Then use a straw to release a drop of food colouring from a height into the glass and watch how it disperses. Even better: try imagining how you think it would look.
Most people imagine the dye forming a cloud of colour that gradually disperses. In reality, the colouring will spread out, apparently without mixing, into surprisingly aesthetically pleasing but random patterns. More often than not, the drop will magically form a ring and travel down to the bottom of the glass without spreading out.
That a drop of liquid could form a ring and move undiluted through water goes against all our intuition. But it shouldn't come as a surprise: fluids are always doing this. The same process lies behind the formation of smoke rings.
Our world is awash with fluid. From the blood that courses through our veins to the cytoplasm in every cell, our bodies are dependent on liquids. And we spend our lives at the bottom of the atmospheric ocean that is fluid air. You can't move without stirring this sea of gases, so ubiquitous they almost go unnoticed.
Given how inextricably linked we are to fluids, it is disconcerting to discover that we do not have a precise mathematical understanding of how they move. Well, we have a working model, but there is no guarantee that it will not one day go horribly wrong.
Any mathematical description of how an object moves when you hit it starts with Newton's equation F=ma (the force applied equals the mass of the object multiplied by the resulting acceleration). Fluids, however, are a collection of countless particles all interacting, so we need a variation on F=ma that takes into account the sum effect across all the objects that comprise a fluid. Then we need to consider its "viscosity", which is a measure of how much the particles resist flowing over each other. Water is a low viscosity fluid while honey is high viscosity.
Put all of this together and you get:
Where u is the velocity of the fluid at position x and this changes over time t. The symbol v is the viscosity of the fluid and p represents pressure.

In 2004, Darfur, Sudan was described as the "world's greatest humanitarian crisis." Twenty years previously, Darfur was also the site of a disastrous famine. Famine that Kills is a seminal account of that famine, and a social history of the region. In a new preface prepared for this revised edition, Alex de Waal analyzes the roots of the current conflict in land disputes, social disruption and impoverishment. Despite vast changes in the nature of famines and in the capacity of response, de Waal's original challenge to humanitarian theory and practice including a focus on the survival strategies of rural people has never been more relevant. Documenting the resilience of the people who suffered, it explains why many fewer died than had been predicted by outsiders. It is also a pathbreaking study of the causes of famine deaths, showing how outbreaks of infectious disease killed more people than starvation. Now a classic in the field, Famine that Kills provides critical background and lessons of past intervention for a region that finds itself in

Home to towering trees, lush plants and fierce predators, the tropical rainforest has long had a hold on the popular imagination. Tropical flowering plants from the rainforest are valued for their unusual blooms, which often exhibit strange and exotic forms, colors and patterns. Though not all tropical flowers are well suited for home gardening, there are many species that are.
A member of the madder family, ixora (Ixora coccinea), also called jungle flame, is a flowering shrub native to the tropical rainforests of Southeast Asia. The plant typically grows to be around 4 or 5 feet tall, although it may grow to be twice that height in ideal conditions. Ixora boasts dense oblong green leaves accented by clusters of brilliant flowers, in colors ranging from scarlet to yellow depending on the cultivar. The plant is best suited to cultivation in USDA zones 9 to 11, preferably with full sun in the morning and partial shade in the afternoon. The plant will tolerate salinity, but not alkalinity, which causes the plant's foliage to yellow. An acidic, moist soil that is watered frequently and enhanced with high nitrogen fertilizer is perfect for this plant.
Nun orchid (Phaius tankervilliae) is an herbaceous perennial native to parts of tropical Asia, as well as tropical Australia. The rainforest plant boasts a 3- or 4-foot stalk of brownish red and white orchid flowers, which appear in the late spring. Nun orchid is not tolerant of cold weather and will only thrive outdoors in USDA zones 9 to 11, though it may be grown as a houseplant in cooler areas. Nun orchid does best in a light shade or dappled sunlight. A moist, well-drained and humus-rich soil is ideal for this plant. Water frequently, but not enough to cause the soil to become waterlogged or soggy.
A native of the tropical rainforests of Brazil, urn plant (Aechmea chantinii "Samuri") is a flowering perennial bromeliad of about 3 feet that sports stiff, thick silvery green leaves. The plant flowers in summer, producing a tall stalk of waxy red or bright orange flowers. Urn plant is a popular specimen or container plant in tropical climates, and is a popular houseplant throughout the world. Urn plant does best in USDA zones 10A to 11A, in partial sunlight. A well-drained, neutral loam is ideal for this plant. Water urn plant frequently, enough to keep the soil consistently moist to the touch. Houseplants should be misted with lime-free warm water to increase humidity.

Hanzhong, Wade-Giles romanization Han-chung, city, southwestern Shaanxi sheng (province), central China. It is situated in a long, narrow, and fertile basin along the Han River, between the Qin (Tsinling) and Micang mountain ranges. To the north one of the few routes across the Qin Mountains joins it to Baoji in Shaanxi, while southwestward a route leads into Sichuan province.
The route into Sichuan was traditionally an important one, linking the Wei River valley, seat of successive dynastic capitals, with the rich Sichuan Basin. The first road was constructed in the 3rd century bce during the Qin dynasty to take carriage traffic. In earlier historical times the area had belonged to the Chu state, based in the middle Yangtze River (Chang Jiang) region. It was annexed in 312 bce by the Qin and established as the Hanzhong Commandery. On the collapse of the Qin in 207 bce, Liu Bang, who as the Gaozu emperor founded the Han dynasty, was installed as prince of Hanzhong; the dynasty takes its name from that of the prince’s fief.
Throughout the ages Hanzhong has remained the administrative centre of the mountainous frontier district between Sichuan, Gansu, and Shaanxi provinces and has been a place of major strategic importance, constituting the key to control of Sichuan. During the Three Kingdoms (Sanguo) period (220–280 ce) it was a battleground between the northern state of Wei and the kingdom of Shu-Han in Sichuan. At this time the city was given the name Liangzhou, which it held intermittently until the 10th century. In 784 it was given the name of Xingyuan to commemorate the fact that the Tang empe

By the month of July, students are happily basking in the midst of summer vacation, without the slightest worry about the impending school year. While the routine of school has been replaced with a relaxing and care-free schedule, one educational task is still needed—reading. Research has concluded that children who do not read during the summer could lose up to three months of progress. With a minimum of ten minutes of reading daily, the goal of surpassing the end-of-year level can be quite simple to attain. Through the guidance of book lists and a number of engaging activities, children can keep on appreciating the splendor of summer while continuing to learn and read.
One of the best ways to acquire high-interest books for your child is to receive a recommendation from your local librarian. He or she will be able to share vital news, such as popular titles or a great series. The public library often features a reading contest, not only to encourage reading among students, but to enable them to participate in the many activities offered during the summer months. Some libraries will have movie nights or scheduled game days, and feature exciting presentations in June, July, and August. Visiting the public library throughout the summer will boost interest and help young children to delight in the routine of reading.
If you are planning a long car ride, consider bringing along a few audio books that would appeal to the entire family. You may be surprised to hear fewer requests to use the bathroom or cries of, “How much longer?” Instead, every passenger will be keenly listening to the narrator’s voice, awaiting the next line. To help you select the right audio book, please be aware that children are able to listen to books up to two years above their reading level. To ensure your child can follow the story, it is important to ask questions as you are listening. Lastly, listening to audio books will improve the skill of listening and retaining information. While not everyone has the keen ability to listen, with time, the skill of becoming an auditory learner will improve.
Letters and Words to Reading Notes
From symbols on sign posts to the names of buildings, reading can be accomplished with a simple game. Allowing your children to be interactive passengers, ask them to read speed limit signs, interpret road signs, and read the names of various businesses and restaurants. With practice, the ease of pronouncing words will improve. Preschool children will also enjoy matching the word with the household object

It's flu season in Baltimore.
A few days after Christmas, Baltimore resident Kathleen Dudley began experiencing telltale signs of the flu — fever, chills, body aches, sore throat, cough and overall exhaustion.
"The worst part — the fever and chills — lasted for about 24 hours," she says. "But the fatigue and cold symptoms lasted much longer."
According to the Maryland Department of Health and Mental Hygiene, between Oct. 1 and Jan. 5, 6,273 Marylanders tested positive for influenza; nearly 30 percent of those positive tests occurred during the week ending Jan. 5.
"According to the [Centers for Disease Control and Prevention], this year's flu season is among the highest in recent years," says Dr. Marc Leavey, an internal medicine physician with Lutherville Personal Physicians.
"The flu is a serious disease," he says. "Every year, thousands of people die from the flu. You can't shake off the flu, and if you've never had it, consider yourself lucky. But luck runs out."
For those who think it's too late for a shot or are holding onto other myths about the flu, we asked local experts to give us answers about how to prevent getting the influenza virus and what to do if you already have it. Hint: Chicken soup is good for more than the soul.
What are the basic steps I should take to avoid getting the flu?
"Get a flu shot, wash your hands and use common sense," says Leavey.
The flu vaccine is especially important for people at higher risk for flu complications. "If you have medical problems or are elderly or young, you are at higher risk for complications of the flu," says Dr. Joi Johnson-Weaver, a family medicine physician at GBMC at Perry Hall.
During this flu season in Maryland, 47 percent of people who have been hospitalized because of influenza were 65 or older.
Who should get the flu shot?
"The CDC recommends that everyone age 6 months and up should get the shot," says Johnson-Weaver.
Flu season typically begins in the fall and lasts through the spring. Though it is currently midseason, physicians stress that it is not too late to get the shot. "In fact, even if you have had the flu, the CDC recommends that you get a flu vaccine," says Leavey. The vaccine can still protect you from other strains of the disease.
However, people with certain conditions, including allergies, current febrile illness or a history of Guillain-Barre syndrome, may not be good candidates for the vaccine. If you have any doubts about whether you are an appropriate candidate, talk with your physician before getting the vaccine.
How do I get the flu shot?
"The easiest way," says Leavey, "is to ask your physician. The flu vaccine is normally covered by health insurance and Medicare, and there are free flu shot clinics throughout the area. You can check online or call your local health department for information."
Flu shots are also available at many pharmacies and through some employers.
What is the difference between the flu shot and the nasal-spray flu vaccine?
According to Johnson-Weaver, "The flu shot is an inactivated virus that is delivered via a shot. The flu mist is a weakened live virus given through a spray in the nose." Johnson-Weaver says the mist is more effective than the shot, but it is only appropriate for healthy, non-pregnant people between the ages of 2 and 49.
If I get the flu shot, will that guarantee that I won't get the flu?
Not necessarily, according to physicians, who say the vaccine is between 60 percent and 65 percent effective. Each year, says Johnson-Weaver, the vaccine is retooled to match the strain of flu scientists predict will be most prevalent that season.
"Over the last 10 years," she says, "the vaccine has been matched well to the current flu virus."
Still, warns Leavey, not all strains are covered. This year, "The A(H3N2) seems to be a particularly severe strain which may not be well-covered by the current vaccine. It is causing about 10 percent to 15 percent of the cases" this season.
How long does it take for a flu shot to be effective? If I get one this year, do I need another next flu season?
"It takes several weeks for your body to develop antibodies to the influenza virus after getting a vaccine," says Leavey.
He and Johnson-Weaver agree that a flu shot is necessary every year, since each year new strains of the virus circulate.
My office mate seems sick. How can I avoid catching what she has?
The flu is an airborne virus, though most flu viruses are transmitted through touch, according to Leavey. "Don't l

Traditionally, Ma Teng and Han Sui are portrayed as being loyal subjects of the Han dynasty starting with the Ming novel “Romance of the Three Kingdoms” and the various media that has followed it. Ma Chao, Teng’s most famous son, is portrayed similarly.
Han Sui was an officer in modern Lanzhou at the time of the outbreak of the Liang Rebellion and joined the Qiang and Lesser Yuezhi mutineers of the Auxiliary of Loyal Barbarians in late 184. He quickly emerged as rebel leader alongside his colleague Bian Zhang. Ma Teng, half-Qiang himself, was a foot soldier in the government armies rising to major under Inspector Geng Bi by 187. He claimed descent from Ma Yuan, a famous general who helped establish the Later Han dynasty.
Following the inspector’s death in battle, Ma Teng switched sides and quickly caught attention. He styled himself a general under Wang Guo, the new rebel leader. When loyalist forces under Huangfu Song defeated Wang at Chencang during an attack on Chang’an and deposed in 189 Ma Teng took control of Longxi commandery, fighting the Qiang and Di. From there he exerted control over the middle Wei River as one of three main rebel commanders. Han Sui, holding Jincheng commandery, was another and commanded the majority of the Liang troops. Song Jian, who adopted the grandiose title “King of the Sources of the Yellow River, Pacifier of Han”, was the third and later set up an independent state from his base at Fuhan.
With the turmoil caused by the Han succession disputes and Dong Zhuo’s coup no one paid attention to events in Liang province. Dong, however,

THE SUFFRAGETTES’ TREE: CENTENNIAL EVENTS IN CELEBRATION OF INTERNATIONAL WOMEN’S DAY (pdf), Bath, 7th—11th March, 2011
Between 1909 and 1912, over sixty suffragettes who were recovering from the harsh treatment they had received while imprisoned for their political activism came to stay with the Blathwayt family at Eagle House in Batheaston, Somerset. As committed supporters of the women’s movement, the Blathwayts wanted not only to help the women recover physically, but also to record, in the very landscape, the cause for which they struggled. As such, they created a very special garden in the grounds of their villa, encouraging the suffragettes who stayed with themto plant trees and bushes commemorating their efforts and their hopes for the future of women's political equality.
Photographs of this beautiful field of trees, or ‘Annie’s Arboretum’ as it was also called, after the suffragette Annie Kenney, can be viewed online via Bath in Time (www.bathintime.co.uk — see ‘Social History’).

Streaming Video in movie format about Paharpur: archaeological site
Paharpur an important archaeological site in Bangladesh, situated in a village named Paharpur (Pahadpur) under the Badalgachhi Upazila of Naogaon district. The village is connected with the nearby Railway station Jamalganj, the district town Naogaon and Jaipurhat town by metalled roads. It is in the midst of alluvial flat plain of northern Bangladesh. In contrast to the monotonous level of the plain, stands the ruins of the lofty (about 24m high from the surrounding level) ancient temple which was covered with jungle, locally called Pahar or hill from which the name Paharpur is derived.
The site was first noticed by Buchanon Hamilton in course of his survey in Eastern India between 1807 and 1812. It was next visited by Westmacott. Sir Alexander Cunningham visited the place in 1879. Cunningham intended to carry out an extensive excavation in the mound. But he was prevented by zamindar of Balihar, the owner of the land. So he had to be satisfied with limited excavation in a small part of the monastic area and top of the central mound. In the latter area he 'discovered the ruins of a square tower of 22 feet side with a projection in the middle of each side'. The site was declared to be protected by the Archaeological Survey of India in 1919 under the Ancient Monuments Preservation Act of 1904.
Regular and systematic excavation was jointly started here in 1923 by Archaeological Survey of India, varendra research society of Rajshahi and Calcutta University. In the beginning the joint mission carried out the work with the financial help of Kumar sarat kumar ray of Dighapatia Zamindar family and under the guidance of DR Bhandarkar, Professor of Ancient History and former Superintendent of Archaeological Survey of India, Western Circle. The work was confined to a few rooms at the south-west corner of the monastery and the adjoining courtyard. The work was resumed in 1925-26 by RD Banerjee, who excavated in the northern part of the central mound. From the next season (1926-27) onward excavation was carried out under the supervision of KN Dikshit with the exception of seasons of the 1930-32. In these two seasons GC Chandra conducted the excavation. In the last two seasons (1932-34) the work was carried out at satyapir bhita, a mound at a distance of 364m east of the central temple. During Pakistan period lower levels of a few monastic cells on the eastern wing were excavated by Rafique Mughal, but the results were never published.
After independence the site was further brought under excavation by the Department of Archaeology of Bangladesh. The operations took place in two phases. The first phase was initiated in 1981-82 and continued in every season up to 1984-1985. The second phase was started in 1988-89 and continued in the next two seasons up to 1990-91. In the first phase excavations were aimed at establishing the three major building phases of the cells which Dikshit mentioned in his excavation report and discovering the information of early levels. But in the second phase the works were confined to clear the cultural debris from the courtyard of the monastery.
Architectural remains Pre-liberation expeditions have revealed the architectural remains of a vast Buddhist monastery, the somapura mahavihara, measuring 274.15m N-S and 273.70m E-W. This gigantic establishment with surrounding 177 monastic cells, gateways, votive stupas, minor chapels, tank and a multitude of other structures for the convenience of the inmates, is dominated by a central shrine, conspicuous by its lofty height and architectural peculiarities. It is distinguished by its cruciform shape with angles of projection between the arms, its three raised terraces and complicated scheme of decoration of walls with carved brick cornices, friezes of terracotta plaques and stone reliefs.
The monastery The entire establishment, occupying a quadrangular court, has high enclosure walls, about 5m in thickness and from 3.6m to 4.5m in height. Though the walls are not preserved to a very great height, but from their thickness and massiveness it can be assumed that the structure was storeyed commensurate with the lofty central shrine. In plan it consists of rows of cells, each approximately 4.26 ´ 4.11m in area all connected by a spacious verandah (about 2.43 to 2.74m wide), running continuously all around, and approached from the inner courtyard by flight of steps provided in the middle of each of the four sides.
There are in all 177 cells, excluding the cells of the central block in each direction; 45 cells on the north and 44 in each of the other three sides. The central block on the east, west and south sides is marked by a projection in the exterior wall and con

Joe O’Donnell, the man who took this photo at Nagasaki, was sent by the U.S. military to document the damage inflicted on the Japanese homeland caused by air raids of fire bombs and atomic bombs. Over the next seven months starting September 1945, he traveled across Western Japan chronicling the devastation, revealing the plight of the bomb victims including the dead, the wounded, the homeless and orphaned. Images of the human suffering was etched both on his negatives and his heart.
In the photo, the boy stands erect, having done his duty by bringing his dead brother to a cremation ground. Standing at attention was an obvious military influence. Looking at the boy who carries his younger sibling on his back, keeps a stiff upper lip, tries so hard to be brave is heart-breaking. He has epitomized the spirit of a defeated nation.
Years later Joe O’Donnell spoke to a Japanese interviewer about this picture:
“I saw a boy about ten years old walking by. He was carrying a baby on his back. In those days

By Burhan Razi | –
The current world economy is structured in such a way that the fossil fuel industry has unquestionable hegemonic power. Developed and developing economies alike need energy to sustain and grow. This energy market is monopolised by the fossil fuel industry.
Oil, natural gas and other energy producing fossil fuels have not only helped build some of the biggest companies in the world, but have also aided the development and solidification of certain national economies like the Gulf states and Venezuela.
This monopoly in the energy sector seems to have given oil corporations power over states – allowing certain companies to be careless in cleaning up massive oil spills, such as the one in Ogoniland, Nigeria.
One could argue that Nigeria has had a harder time dealing with its oil spill as compared to the United States, because of its weaker political clout in the international arena. In 2010, the US government made BP accept its moral responsibility for the oil spill in the Gulf of Mexico, and fined the company $18.6 billion for a one-time occurrence. Whereas in Nigeria, there have been a number of oil spills and nobody has taken full responsibility.
A UNEP report says that cleaning up Ogoniland might take up to 30 years.
That’s three decades of hard work to rectify the destruction caused by an aloof and irresponsible corporation. Damage to the environment to this degree is absolutely criminal and there should be some form of retribution.
Yet, nothing has happened. The world sleeps while Ogoniland becomes inhabitable.
Oil spills can be extremely damaging for the environment, as evidenced by environmental damage caused in Nigeria and the Gulf of Mexico, but for me, the bigger problem is oil itself. Oil companies are surreptitiously causing an even bigger environmental hazard by emitting Green House Gases (GHGs) into the atmosphere. Moreover, their hold over the global economy and their power grabbing ways has made it difficult for the world to endorse renewable energy.
While many countries are trying to reach a deal for the future of our planet in Paris, big oil has been constantly lobbying to make it difficult for an agreement to be reached. Fortunately for us, they are fighting an evolving economy, one that won’t have much room for them in the future.
The elephant in the room, and the third reason to be wary of fossil fuels, comes from a seventh grade geography book – fossil fuels are called non-renewable energy sources because there is a finite amount that we can dig up. Oil wells will eventually run dry, and when they do, the world economy will be in a flux.
In fact, even before the wells dry up, we can foresee a situation where demands would far exceed the supply and prices would start shooting up. The process has already begun.
We are all well aware of the fact that a scarcity of resources can lead to intense competition and outbreak of violence. One of the reasons for the civil war in Syria has been the diminishing supply of water in rural areas.
Unfortunately, a recent study has revealed that Pakistan has much higher oil and shale gas reserves than what was previously known. For me, this finding is a curse disguised as a natural resource blessing. As the world moves closer to an agreement on climate at the Conference of Parties (COP) in Paris, the prevailing economic structure in the world is going to have a fundamental transformation, where renewable and green energy sources will eventually completely phase out fossil fuels. While big oil is spending hundreds of millions trying to promote the fossil fuel industry, public opinion in developed countries like the US is definitely in favour of action against climate change.
Having said that, let’s bring the issue back home.
Why should Pakistan care about climate change and big oil?
Given that we have vulnerable areas and people are already being affected by climate change, we need to become cognisant of our environmental situation. Although, all of us would certainly like the idea of having some of our own oil to ensure self-sufficiency in the energy sector, we desperately need to allocate some of our resources into developing renewable forms of energy in the country.

Acne - Skin condition characterized by plugging and inflammation that involves the hair follicles and sebaceous glands. It can take many forms including blackheads, whiteheads, papules, pustules, and nodules.
Acne vulgaris - Medical term used to describe acne.
Adult-onset acne - Overwhelmingly a condition of females, this type of acne turns up after the age of 18. It can crop up in women's 20s, 30s, or even later in life. It's sometimes referred to as female adult acne or post-adolescent acne.
Alpha hydroxy acids (AHAs) - Fruit acids found in plants, constituents of many over the counter acne and cosmetic products, such as moisturizers and sunscreens. Also used in chemical peels.
Allantion - A derivative of uric acid that is soothing and calming to the skin.
Androgens - General term for hormones that have masculinizing features. Both males and females produce them. They cause the sebaceous gland to enlarge and produce more sebum, an important factor in the development of acne.
Antioxidants - Chemicals that neutralize free radicals that cause damage to the body and skin. These come from eating fruits and vegetables and also can be applied topically to help heal the surface of the skin.
Astringent - Solution that removes oil from the skin. Often used after a facial wash to remove any remaining traces of a cleanser.
Azelaic acid - Natural chemical produced by yeast. Used as a topical agent to treat acne and rosacea. It can also also be used to lighten the skin.
Basal Layer - The lowermost layer of the epidermis. This layer provides replacement cells that travel upward and replenish the skin with new cells.
Benzoyl peroxide - Topical antibacterial agent used to treat acne. Found in more over the counter and prescription products than any other topical agent.
Beta hydroxy acids (BHAs) - A class of acids, including salicylic acid, that are used as exfoliants. They're found in many over the counter acne and cosmetic products, such as moisturizers and sunscreens. They're also used in chemical peels.
Blackhead - An open comedo. The dark acne lesion that consists of a plug of keratin and sebum. The dark color is due to a buildup of melanin.

Oddities of Physics (Oct, 1937)
Oddities of Physics
Science is much closer to our daily lives than many of us believe. Some of the simplest phenomena and everyday occurrences which do not strike one as of any particular interest, abound with scientific explanations.
WHO would imagine, when watching soldiers marching across a bridge, that they do so under orders to “break step.” If this were not done there would be a rhythmic motion set up in the bridge structure—a steady tramp-tramp—which would likely disrupt any small bridge and perhaps even a very large one (Fig. 1).
Can a submarine remain stationary at any desired level?
The answer is that it cannot, unless a slight headway is maintained or water is admitted to and discharged from the trimming tanks. A submarine cannot find a state of hydrostatic equilibrium or a point at which all pressures are equal.
Is it possible for a ship like the Titanic to sink in deep water, and eventually reach a point where the water pressure is great enough to prevent the ship from settling to the bed of the sea?
Although this question has been argued pro and con many times in the columns of scientific journals, the fact remains that no such effect will be found; the wrecked ship will descend until it rests on the ocean bed.
How fast would an airplane have to fly to leave the influence of this earth forever?
Scientists have computed, that any space flyer would have to be hurled from the earth at an initial velocity in excess of 7 miles per second. Such a ma- chine would reach the moon in less than 10 hours. (However, gradual acceleration could effect a departure, without such a high starting speed.) Could one man hold a Zeppelin?
The answer is yes, if the ship is carefully trimmed and balanced, as is the case when she is just brought out from the hangar preparatory to a flight.
Does putting oil on the water help to quiet angry waves?
Yes, this is a regular recognized practice at sea when the waves are running high and a ship is in distress. The oil helps to prevent white caps, but it does not stop the general swell of the waves.
Does the rotation of the earth cause wear on certain banks of a river?
Yes, theoretically, at least. There doesn’t seem to be any measurable proof. In rivers running north and south, in the Northern Hemisphere, there is a tendency to wear away right-hand banks, as shown in the diagram in Fig. 7, due to the rotation of the earth. In the Southern Hemisphere it is the left-hand banks that receive the most wear.
How does science help in releasing a tight pulley.’ A usual method of removing a pulley is to apply heat from a blow-torch to the pulley and ice bags to the steel shaft. The resulting contraction and expansion often permit the removal of the pulley when it otherwise refuses to yield.
Fig. 9 shows one way to stop a “flue” fire, simply by placing a cap or pan over the top of the chimney and thus checking draft of air through the chimney. Another trick is to put salt in the fire in a stove con- nected with the burning flue; the gases gen-crated help to snuff out the flames in the chimney.
Fig. 10 shows how violins and other high-pitched instruments are placed near the “mike” in broadcasting, while the bass violins, etc., are placed further back. The low notes, emitted by bass instruments, have more energy in them, or are stronger than the high-pitched notes coming from the flute, violin, etc., hence, in broadcasting studios, the majority of wind instruments are usually placed further away from the “mike,” as are drums, etc.
An interesting and everyday occurrence in homes and offices is the vibration of a metal picture frame, or other similar object, when a certain note is sounded on the piano, or radio (Fig. 11). This is due to the fact that the frame has a natural frequency corresponding to the note struck, hence it vibrates sympathetically.
It is not generally known that if a high voltage direct current is passed through a wire grid in a chimney, smoke from the boilers can be eliminated. The high voltage electrical charges cause the carbon particles, comprising the smoke, to become charged and they are precipitated to the bottom of the stack.
Fig. 13 shows an interesting problem which public address engineers have to conjure with at times. A person sitting a certain distance from the speaker’s platform may experience the unusual sensation of hearing the speaker’s voice coming out of the loudspeaker before he hears the natural voice coming from the stage. This is due to the fact that sound travels only at about 1100 feet per second in air, while the electrical current, carrying the voice from the “mike” to the loud speaker, travels at 186,000 miles per second. Consequently, good judgment has to be used by the engineers in planning P. A. systems.
If a tank full of water has 3 openings, as shown in Fig. 14, the middle jet will produce the longest stream.
Does smoke blowing downward from a chimney indicate rain?
No. This is an old theory, but it has little to recommend it. Smoke rises because of its higher temperature. If the outside air is as warm as the smoke, or if the smoke is “ch

Did you know that your body weight is approximately 60 percent water? Your body uses water in all its cells, organs, and tissues to help regulate its temperature and maintain other bodily functions. Because your body loses water through breathing, sweating, and digestion, it’s important to rehydrate by drinking fluids and eating foods that contain water.
The amount of water you need depends on a variety of factors, including the climate you live in, how physically active you are, and whether you’re experiencing an illness or have any other health problems. While there is absolutely no doubt that we all need water to survive, here are some specific benefits that you may not have know about — cheers to your good health!
Drink water before and after sleeping
Drinking a glass of water before sleep can dilute the thickness of blood and reduce the risks of angina and heart failure, which tend to occur in the early morning. Drinking a glass of water in the morning gets rid of waste through sweat and urination, which reduces the risk of kidney stones and UTI’s (urinary tract infections).
Water helps when you have a cold or flu
When you are sick with a cold or flu, your body sweats and you urinate more as your metabolic rate increases. Water in your body is lost faster than normal and you need to take in more to make up for the shortfall. Water can also reduce your body temperature and helps to flush out harmful bacteria. Inhaling steam from a humidifier or pot of boiling water can help clear up congestion, while salt water can also break up all the gunk that makes you stuffy.
Eat water and rice porridge for an upset stomach
A small bowl of water and rice porridge is helpful for an upset stomach. The temperature of the porridge should be at least 140°F (60°C), so that a gelatinization can be produced to soothe the stomach and to make digestion easier. The porridge can also lubricate the bowels and move out toxins.
Water helps to prevent constipation
Water helps to prevent constipation by dissolving fats and soluble fiber. It also reduces the burden on the kidneys and liver by helping to flush waste products. In the large intestine, water binds with fiber to increase the bulk of the stools, reduce transit time, and make elimination easier. When you don’t drink enough water, the lining of the intestine pulls water from your stool, increasing your risk of constipation.
Water helps to expel harmful substances
Nausea is how the body protects itself when bad food is ingested. Vomiting, while gross, is beneficial as it is your body’s way of eliminating harmful substances in the stomach and gut. If vomiting is difficult, a glass of lightly salted water can be used to stimulate vomiting and to supplement water in the body after vomiting.
Water helps to reduce weight
Anyone looking to lose weight could be helped by upping their water intake. Studies have found that when people drink water before a meal, they lose weight faster than those who do not drink water. An extra amount of water helps you eat less by making you feel full, and it may also boost your metabolism.
Water helps you get a good night’s rest
Your body temperature plays a big role in getting a good night’s rest. A hot shower or bath before you go to bed raises your body temperature a degree or two. The steep drop in temperature at bedtime is more likely to put you into a deep sleep.

SOURCE AND SINK RELATIONSHIP IN CROP PLANT
Source and sink relationship is studied to get better yield, to understand the relationship between the source of assimilation and the sink in which dry weight is accumulated as economic yield.
The organ that synthesizes food materials is called a source, in crop plants the mature leaf is always a source. Then the organ that accumulate the synthesized food material is known as a sink. The source is the potential capacity for photosynthesis (Po) and the sink is the potential capacity to utilize the photosynthetic products of the source. For example in wheat grain in the part of starch is the photosynthetic product of the leaves which then trans located directly to the fruiting grain after flowering
The ripening of wheat grain can be considered a process of accumulation of content. The grain yield may be limited by either the amount of its contents. If the contents are small the yield cannot be high. On the other hand, even if the contents are large, the yield cannot be high if the content is limited. Their procedure and active appear to determine the nature of crop performance.beevers (3) and Evans (15) gave some broad indication of source and sink. Molecular level transformation s involving volume flow of assimilates, phloem loading and unloading, general assimilates pools, and metabolic step in multiple enzyme systems with coupled biochemical processes were covered in a very basic way by Gifford et al ( 17), Hendrix et al (21), the scope of this review is limited to structural and productivity level of source and sink.
SOURCE AND SINKS
The continued growth of any plant depends primarily on photosynthetic activity in the leaves and the transport of organic compounds from the leaves to hetertrophics cells. The source supplies assimilates (C compound) to the sink. The sink accepts and consumes the assimilates for its own growth or accumulates them for a certain period. the sink source relationship resembles the demand –supply relationship in economics (52). In general, any plant part that has photosynthetic ability is considered a source, and non green cells, tissue, and organ are considered sinks. Thus, leaves are typical source, and stem, roots and tubers are typical sinks. The sink and source functions of any plant part may chage depending on its developmental stage for example, in rice, before flowering, the leaf sheath and culm accumulates sugars and starch i.e. act as sinks ( 79). After flowering, most of the accumulated carbohydrates move into spiklets (10).
Developing organs, tubers, nongreen aeriel plant parts, bud, flowers, fruits, and most of the cells in stems and petioles also constitute a drain on photosynthetic products and are thus sink. Even within leaves there are many cells without chloroplasts. And the autotrophics cells themselves consume photosynthate in their own growth and respiration.

Why Some People Have Cold Feet?
If you are reading this article then you are probably looking for more
information regarding why some people have cold feet.
Some people get cold feet at bedtime and this is a common aggravation.
This problem develops because our body temperature drops slightly when
people get ready to go to sleep which can result in cold extremities.
Peripheral neuropathy which is also known as impaired circulation to
the feet is a common cause of chronic cold feet. This is more likely to
occur in people with diabetes, elderly people or inactive individuals.
hello its me again
hello its me again
why oh why
Another circulation problem, peripheral vascular disease narrows blood
vessels which restricts blood flow. This can result in raised blood
pressure along with cold feet and fingers.
An individual with ateherosclerosis may also suffer from chronic cold
feet. This is a condition where fatty material adheres to artery walls
which also causes angina and high blood pressure. Anemia can also cause
cold feet, this is a condition where an individual will have a low
level of healthy red blood cells which also results in headaches and
Another Factor could be Rynanuds Sydrome Parasites which are harmful
organisms that enter your body can also be
responsible for cold feet. They will absorb and eat the nutrition that
is necessary in order to maintain good health. Diagnosing body
parasites can be very difficult, however if you do suffer from chronic
cold feet sensations then it is important that you have body cleaned of
Allergic reactions can also be another cause of cold feet. Allergies
can result in decreased blood pressure which can result in cold feet
and hands. Therefore it is important to monitor your food intake and
watch out for allergenic foods.
The temperature of the feet is determined by the combination of outside
temperature and the level of circulation you have, the less amount of
blood that gets to your feet, the colder your feet will become. four
It is important that you have a regular cardiovascular workout in order
to fight and prevent the problem of cold feet. If you exercise
regularly then this will increase the blood flow and reduce the risk of
you getting cold feet.

The Sabbath was not just created; it was made with someone in mind. The prevalent idea today is that the Sabbath was made "for the Jews"—but that is not what Christ says! Christ says it was made "for man"! It was something created for the benefit of all of mankind, not just for a certain group of people. God created the Sabbath immediately after He created the human race—not at the origination of the Jews:
Verse 31 shows that this happened on the sixth day of creation week. Further, man was the very last thing or being created on that day. Man came into being, then, probably in the late afternoon of the sixth day.
When "God said, 'Let Us make man,'" who spoke? As John 1:1-3, 14 shows, Jesus Christ is also called the Word—that is, the Spokesman. He speaks only as the Father directs. God created all things by Jesus Christ (Ephesians 3:9; Colossians 1:16). Therefore, the One who became Jesus said: "Let Us make man." Jesus did the work of creation, as instructed by the Father.
Notice that He did not complete His creating on the sixth day, but it continued through the seventh day: "And on the seventh day God ended His work which He had done." God ended His work, but the creation week was not yet over! Creation Week was a full seven days of creation.
What did He create on the seventh day? He made the Sabbath! However, He made the Sabbath, not by work, but by ceasing from it. On the seventh day He ended the work of creation—what was created by work. He rested on the seventh day, and by doing so, created the Sabbath. He then blessed and set apart the seventh day as a day of rest and worship for mankind.

Chapter 1: Introduction
Five hundred years ago, royal and noble parents arranged their daughters’ marriages to men of appropriate rank, selected for political advantage. Romantic love was frowned upon and certainly no basis for matrimony.
For a second marriage, a woman might exercise an element of choice, provided the man was of suitable degree - for status was everything, and to make a match that “disparaged” your blood might lead to you being cast off by your kin. Despite the risk of ostracism, love occasionally triumphed and women asserted themselves to marry lower-ranking husbands. Provided both parties stood by each other, no amount of outrage on the part of relatives could break up an unsuitable union, as the only requirement for a valid marriage was consent. Neither priest, parental consent, nor a ceremony were necessary.
Between 1430 and 1565, seven ladies close to the throne braved royal wrath and scandal by marrying men of lower degree for love.

Consuming high-fat dairy products may lower risk of type 2 diabetes, study
People with the highest consumption of high-fat dairy products (8 or more portions per day) had a 23 per cent lower risk of developing type 2 diabetes than those with the lowest consumption (1 or less per day), according to research from the Lund University in Sweden.
The research, presented at this year’s annual meeting of the European Association for the Study of Diabetes (EASD) in Vienna, Austria, was undertaken by Dr Ulrika Ericson and colleagues from the Lund University Diabetes Center, Malmö, Sweden.
Dietary fats could have crucial role in type 2 diabetes development
Previous research has found that dietary fats could affect glucose metabolism and insulin sensitivity and may therefore have a crucial role in the development of type 2 diabetes. Some studies have indicated that replacing saturated fat with monounsaturated and polyunsaturated fats might be favourable in the prevention of type 2 diabetes.
In line with this, plant sources of fat have been suggested to be a better choice compared with animal sources. Indeed, high intakes of red meat and meat products have been shown to increase the risk of type 2 diabetes.
High dairy intake could be protective
Nevertheless, several epidemiological studies have indicated that a high intake of dairy products may be protective. Subsequently, according to the Lund University researchers, the importance of dietary fat content and food sources of fat remained to be clarified.
In this new study, the researchers aimed to examine intakes of main dietary fat sources, classified according to fat content, and their association with risk of developing type 2 diabetes.
“Our observations may contribute to clarifying previous findings regarding dietary fats and their food sources in relation to type 2 diabetes,” said Dr Ericson. “The decreased risk at high intakes of high- fat dairy products, but not of low-fat dairy products, indicate that dairy fat, at least partly, explains observed protective associations between dairy intake and type 2 diabetes,” she said.
The study included 26 930 individuals (60 per cent women), aged 45-74 years, from the population-based Malmö Diet and Cancer cohort. Dietary data was collected with a modified diet history method.
During 14 years of follow up, 2860 incident type 2 diabetes cases were identified. Modelling was used to estimate hazard ratios (HR) of diabetes incidence in quintiles of energy adjusted dietary intakes. The model included adjustments for age, sex, season, diet assessment method version, total energy intake, BMI, leisure time physical activity, smoking, alcohol consumption and education.
The researchers found that high intake of high-fat dairy products was associated with a 23 per ce

One of the mysteries of the English language finally explained.
A type of sledge formerly used by North American Indians to carry goods, consisting of two joined poles pulled by a horse or dog.
- ‘With their wounded strapped to travois, the Nez Perces made their way through the Big Hole and Horse Prairie valleys.’
- ‘Prior to the introduction of horses to North America, tipis were small, 8 to 14 feet in diameter, since the poles and buffalo skin coverings were pulled on travois from one encampment to another by dogs or women.’
- ‘Women rolled lodge skins, secured packs, and hitched travois.’
- ‘Behind the huge caravan of people, travois, and pony herds, some 120 freight wagons carried supplies and indigent Indians.’
- ‘They all then prepare to return to Drexal making travois for the injured.’
- ‘When he wanted to travel, he called for his braves, and they would carry him upon a travois, an A-shaped frame made of long poles and a deerskin platform.’
- ‘You should have it with you all the time, and you never know when you may need to cut a wading staff, build an emergency shelter or even make a travois to get an injured buddy back to camp.’
- ‘Described as ‘roads’ by fur traders, these trails were further rutted by the dragging of lodge poles and numerous travois behind laboring horses.’
- ‘A story of Ka-mina-kus, a legendary warrior, seems to be taken directly from Grinnell's account (Grinnell 107-08; Paget 151-52), as does a description of the travois, a type of dog-pulled or horse-drawn vehicle.’
- ‘The Indians also have the skill to pack up their tepees and travois and set them up elsewhere.’
- ‘For example, using descriptions gleaned from his extensive research, Henderson attempts to replicate an Hidatsa dog travois (a wood and sinew A-frame sled) and then train a short-haired Husky to pull the outfit.’
- ‘The families walked the 140-mile trip and children and elders rode on lodge-pole travois dragged by ponies and loaded with tents, kettles and food.’
- ‘As the Northern village followed down the White River in the wake of the Red Cloud column, this group traveled at the very rear of the procession, a buckskin horse hauling on a travois the bundle that contained the body of Crazy Horse.’
- ‘Domesticated dogs carried Blackfoot belongings by pulling a loaded travois consisting of two long poles attached to the dog's sides.’
- ‘However, to date, the provincial government is dragging its travois, so to speak.’
- ‘Traveling over great distances, caravans of men, women, and children, amid crowds of dogs, herds of horses, and the clatter of travois, crossed the high, windswept passes punctuating the Continental Divide.’
- ‘Being ‘light and young and active,’ he climbed up a travois leaning against the stockade and sprang over and into the willows.’

Choice To Act Upon It A Characterization Essay About Hamlet Essay, Research Paper
In HAMLET, a tragic play written by William Shakespeare, Hamlet, the main and most controversial character, will have readers looking more deeply into their inner self to examine their habitual ways. Shakespeare uses Hamlet’s self-pitying and self-centered character as an instrument that instructs the reader to evaluate his or her own interaction and communication with people. When life-threatening choices confront Hamlet, his actions, attitude, perception of reality, and speech illustrate how self-centered he is.
Throughout the play, Hamlet is confronted with three sickening and hard situations. He is forced to make decisions that will affect himself and everyone who is circling ’round him and his so-called madness. One of the first conflicts the reader is presented with is Presented with is the “increase of appetite” in Gertrude’s sexual drive, or rather the incestuous marriage between Gertrude and Hamlet’s uncle Claudius, which is a lot for the son of the murdered King to deal with (I.2.148). This is quickly followed by Hamlet finding out that if he doesn’t “revenge his foul and most unnatural murder,” or rather that Claudius was the one who killed Late Hamlet his Dad will be “Doomed for a certain term to walk the night” (I.5.31, I.5.15). And not only is this information presented to Hamlet, but by a Ghost representing his father, which might cause him to think he’s going mad. Lastly, Hamlet’s one love, Ophelia disregards Hamlet’s love for her showing the actual written proof of love, the love letters, to her father. This causes other characters in the play to believe that Hamlet’s madness is derived from the fact that Ophelia has disregarded his love for her.
In the beginning of the play, Hamlet still has a clean slate, because he hasn’t made a choice yet of what to do about what he’s been confronted with. The readers still feel sympathy for him, because of the incestuous marriage ordeal. Hamlet has the choice to tell the authorities what he heard from the Ghost. He could have received justice for what had been done, with no one being hurt, and still received plenty of sympathy from the townspeople. Instead, he takes the selfish, and most often taken path, when he takes matters into his own hands.
“I am but mad north-north-west. When the wind is southerly, I know a hawk from a handsaw.” (402-403). It’s all an act and Hamlet is not insane. Those who are truly insane don’t proclaim it all the time. He is simply acting in the same fashion that everyone else is. Yes, it was fate for these situations to occur in Hamlet’s life, but he does have a choice in how he handles them. Before he found out about Claudius being a murderer, Hamlet gave the speech that began with “O, that this too, too sullied flesh ” when he was interrupted by Horatio and Marcellus, and like a robot switched gears to being in a totally fine mood, by responding “I am glad to see you well” (I.2.133, I.2.166). Already, he is putting on an act! Also, Claudius often addresses Hamlet in a fake manner, such as “Tis sweet and commendable in your nature, Hamlet” although we know that Claudius dislikes Hamlet very much (I.2. 90-91). In addition, when Gertrude and Claudius ask Hamlet’s good friends, Rosencrantz and Guildenstern, to talk with Hamlet to see how he is really doing, they, too, are being actors. They need to get the truth out of him to try to find out the core of his madness. But, being good friends they tell him “we were sent for,” and this is the moment that Hamlet surely knows that he is being acted upon (II.2.315). It causes Hamlet to think he is going even crazier. He thought he was the smartest– the only one acting. The example that most clearly illustrates this entire acting business is when Claudius and Polonius ask Ophelia if she’ll wait in the courtyard ’til Hamlet comes round so that they can listen in on the conversation. Ophelia, the only one who Hamlet trusts, is also acting! Also when Hamlet declares “I did love you once,” and “Get thee to a nunnery” also proves that Hamlet is acting. Real love, like the kind he has for Ophelia, simply does not disappear (III.1.129, III.1.31). He is simply trying to get Ophelia to feel guilty, and come back to him.
Hamlet has a pattern throughout the play of trying to get people to feel sorry for him. His motivations are: to make himself at ease, to see Claudius go to hell, to ensure his happiness at the expense of others, to ensure everyone knows how bad he has it, and to play the victim role. Throughout the

The greater part of its body is covered by a pattern of acanthus leaves, but on the shoulder is a frieze showing nomads breaking in wild mares, our chief authority for Scythian costume.
The kings of arms in England, Scotland and Ireland wear crowns, the ornamentation of which round the upper rim of the circlet is composed of a row of acanthus or oak leaves.
There are two types, that found in the Acanthus spinosus, which was followed by the Greeks, and that in the Acanthus mollis, which seems to have been preferred by the Romans.
Large flowing leaves of acanthus and other plants were beaten out with wonderful spirit and beauty of curve.
It has twenty-four columns of Carystian (cipollino) marble, with capitals probably of Byzantine work with swelling acanthus leaves; but the rest of the church is due to native architects.
The best - known is Acanthus mollis (brankursine, or bears' breech), a common species throughout the Mediterranean region, having large, deeply cut, hairy, shining leaves.
In decoration, the acanthus was first reproduced in metal, and subsequently carved in stone by the Greeks.
Another species, Acanthus spinosus, is so called from its spiny leaves.

What does this mean for you programmers who write in python? Well it means that we will no longer have to use and import multiple libraries to convert bases.
As most people have noticed pythons
int() only supports one way base conversions.
int('lol',36) // => 28101. Pythons
format() also only supports conversion the other way up to base 16. This library was created to help those python programmers by providing a bases conversion system that works both ways, can use customized conversions and supports from base 2 all the way up to base 64 all in one library.
I hope everyone enjoys this library especially now that it can be installed with pip.
If you feel like using it then give it a spin.
pip install bases.py
from bases import Bases bases = Bases() bases.toBase16(200) // => 'c8' bases.toBase62(99999) // => 'q0T' bases.toAlphabet(300, 'aAbBcC') // => 'Abba' bases.fromBase16('c8') // => 200 bases.fromBase62('q0T') // => 99999 bases.fromAlphabet('Abba', 'aAbBcC') // => 300
Going from numbers to strings:
toAlphabet(num, alphabet): returns a string representation of the given number for the given alphabet, where the alphabet is an arbitrary string of characters. (See known alphabets below for examples.)

October 7, 2005
Wabash has multiple connections to the Civil War's Andersonville prisoner abuse trial, a dramatization of which is being performed at the College this Friday and Saturday night.
While Wabash alumnus General Lew Wallace, Class of 1840, presided over the actual trial, the College archives also contains a diary written by a Union soldier who was a prisoner at the notorious Andersonville stockade. Archivist Emeritus Johanna Herring recently completed the first transcription of a diary written by Thomas Asbury Gossett, who was a member of Company One, Seventh Regiment of the Indiana Volunteers during the Civil War.
She says the diary is "rich in descriptions of daily life at Andersonville and other Confederate prisons."
"Research on other Andersonville diaries reveals a tendency for authors to exaggerate the horrors they experienced so the diaries would sell better," Mrs. Herring says. "They also tended not to describe the positive acts of southerners towards Federal troops. The Gossett diary seems to be fairly balanced between detailed accounts of the extreme hardships he endured and the kindnesses of the 'enemy,' when they occurred."
The horrors described include this description atrocities committed at the stockade's "Dead Line:"
"Stakes were driven inside of the stockade and formed a line that prisoners were not allowed to pass without punishment; this formed the celebrated dead line. The guards stationed in their sentry boxes were ordered to shoot down without warning any man who passed this dead line, and every guard who killed a Yankee was allowed a furlough for thirty days.
"Providence Spring was on the west dead line and a scene was enacted there one day which even now to think of it sends the blood in a cold strain through my veins. A great many of us were about the spring getting water when a poor crazy man happened to step over the dead line. The guard fired, missed the offender, and hit three innocent men.
"Such reckless shooting was no uncommon thing. A member of my own regiment, Maurice Prindeville, was thus shot in the night when asleep and while lying at least ten feet from the dead line. The bullet took effect in the top of the head, tearing the skull to pieces in a shocking manner. Poor Maurice never knew what hurt him. We were so thick on the ground that it was almost impossible for a bullet to enter the stockade without hitting someone. I have no doubt but some men crossed the dead line on purpose to be killed and thus put an end to their sufferings, choosing to die a quick death by the bullet rather than a slow one by starvation & disease."
The diary was donated to the archives in the 1990s by Thomas Asbury's descendant, Andrew Keith Houk ’37. A copy of the diary's transcript will be available later this month in the College's Robert T. Ramsay, Jr. Archival Center.
The Andersonville Trial, Saul Levitt's dramatization of the trial of Andersonville prison camp commander Captain Henry Wirz, continues performances at 8 p.m. on Friday and Saturday in Ball Theater on the Wabash campus.

Weight is the resistance to movement in a straight line. Lifting is an example. The racquet resists (does not move) your lifting efforts until you pull with a force equal to its weight. Then you can lift it. Weight is what you feel if you pick the racquet up by the tip or handle while allowing the opposite end to hang straight down to the ground. Weight is also what you feel if you pick the racquet up at the balance point. Weight influences balance and swingweight, but by itself, pure and simple, it is rarely what the player is directly experiencing when interacting with the racquet.
The balance point of a racquet is that point along the length of the racquet where a racquet will teeter and totter on a thin support (like a 1/2" dowel or the edge of a ruler) without one end or the other being pulled to the ground. If the racquet balances halfway up the racquet from the butt, it is said to have even balance. If the balance location is more than half way up the racquet, it is said to be "head-heavy," because the shorter head "half" counter-balances the longer handle "half." Finally, if the balance location is less than half way, the racquet is said to be "head-light" because now the head-side "half" is longer and counter-balances the shorter handle-end of the racquet.
Unfortunately, "head-light" or "head-heavy" does not actually mean one end is lighter or heavier than the other, but just that the mass of the materials is spread out in such a manner that the short side of the balancing racquet behaves heavier. The way it works is that a smaller bit of weight at a great distance from the balance will counter balance a bigger bit of mass at a lesser distance from the balance point.
What is important to know about balance is that the racquet behaves as if all the mass were located at the balance point. That is why it is also sometimes called the center of mass. For equal weight racquets, the closer the balance point (center of mass) is to your hand, the less force (torque) you need to hold the racquet up horizontal to the ground (holding at the handle).
Much of a tennis hit can be seen as a battle between the player and the ball to move the racquet in a circle. Swingweight is the resistance to movement in a circle. Circular motion (as in most stages of a tennis swing) occurs around a center or rotation, let's say the butt end of the handle. When you apply equal forces to the handles of two racquets with different swingweights, the racquet with the higher swingweight will accelerate less and rotate less quickly around the center of the circle. The lower swingweight racquet will accelerate more quickly. In other words, higher swingweight means less maneuverability, and lower swingweight means more.
But the ball applies a force to the racquet also. And the same principle applies. The lower the swingweight, the more easily the the ball will move the racquet, and the higher the swingweight, the less easily the ball will change the motion of the racquet.
So the tradeoff becomes this: lower swingweight results in greater racquet acceleration and final swing speed, but more shock (due both to more racquet deceleration by the ball and higher impact force due to greater speed). Higher swingweight results in slower racquet acceleration and final swing speed but less shock due to less deceleration due to the ball pushing the racquet in an opposite circular rotation.
Power is influenced also. With a lower swingweight, the power must be generated more from swing speed. With a higher swingweight, more of the power comes from the racquet itself.
The beauty of customization is that you can easily experiment and find the best tradeoff for your style of play.

Arctia caja, also know as the “garden tiger moth”, is a moth that can be found in large parts of the world including Europe, Asia, Russia and North-America.
The bright red hindwings of this moth serve as an aposematic warning, as the bodily fluids of this moth contain neurotoxin that may afflict potential predators that eat them. When resting, the hindwings are hidden beneath the forewings. Whenever stressed or disturbed, they will spread their wings and flash their red hindwings as a scare tactic and also a fair warning. They may also shrug their wings to make a “clicking” noise and secrete a bitter-tasting substance in order to be less palatable for predators. Some birds have been observed to eat these moths – but only in small amounts, to minimize the effects of the toxins.
Like typical Arctiids (=tiger moths) the caterpillars are hairy in appearance. Their furry tufts of hair provide protection against cold which is useful, as this species overwinters as caterpillar. They also serve to make the caterpillar unpalatable, as hairs are both hard to digest and swallow and some of the hairs also contain formic acid which may cause irratation. Instead of limiting themselves to a single host plant, the caterpillars are highly polyphagous and will feed from a wide range and mix of plants, usually low growing plants. Some examples include Taraxacum (dandelions), Plantago (plantains), Rubus (blackberries), Pru

What If Peña Nieto Resigns? Scenarios for Government Change in Mexico
Huffington Post: Since the resignation of Pascual Ortiz Rubio in 1932, Mexico has enjoyed uninterrupted presidential continuity, a streak that is unmatched by any major political system in the Western Hemisphere (and possibly among the longest in the world). Over the course of these 82 years, no presidential term has been cut short due to death, assassination, resignation, coup d'état or any other sort political upheaval and as a result, it has become difficult to imagine an interruption to this orderly succession that most Mexicans have taken for granted. However, the outbreak of social unrest from the Ayotzinapa crisis combined with the streak of scandals that have engulfed the presidency of Enrique Peña Nieto over the past two months have perhaps made the unthinkable slightly less so. For those of us in the business of analyzing political and economic risk, the last few years have demonstrated that highly improbable events do in fact take place and therefore deserve a more nuanced look.

How does Weber’s notion regarding the evolution of societies from primitive, irrational types of law to a more “structured system of formal laws” compare to Durkheim’s thoughts on law in societies characterized by mechanical- versus organic-solidarity?
Both Weber and Durkheim believed that societies laid on an ideological ladder of evolution. They considered the structure of the nation-state to be the highest, most advanced structure on the ladder of social evolution. Thus, when studying cultures whose social organization differed from that of their own, both Weber and Durkheim tended to place these societies a lower rungs on the ladder.
For Weber, lower rung communities were not very safe because their law was "irrational." Their law was based on beliefs about community gods and spirit. Weber believed such laws to be fundamentally unstable.
Durkheim also considered the relationship between law, organizational structure, and community structure. For Durkheim, loosely organized clan structures could never achieve the true safety of a nation state because their solidarity was organic -- based on the autonomy of each person, rather than mechanical -- enforced by the state.
Max Weber and Emile Durkheim both came up with some very interesting sociological ideas. In the area you're asking a question about, legal/political development, the two men's opinions share some similarities.
Both ideas are kind of complicated but can be summed up roughly as follows:
Weber would say that people go through three different forms of government.
- Charismatic -- This is the most primitive type of political power, in which a group is held together by the personality of an individual. Some extraordinary leader, religious or not, comes along and tells everybody what to do. People follow because they either fear or respect this individual. When he/she dies, the group must find another charismatic person to run the show.
- Traditional -- After charismatic comes traditional. In this form of political power, things are run they way they are because that's the way they've been done for a long time. Fathers pass power on to sons who then become heads of their own households. An example of this can be seen in feudalism, in which political power and land rights are generational.
- Rational -- In this more "evolved" type of authority, a logical legal code is created to govern behavior. A class of bureaucrats comes into existence to monitor and enforce the law, but the true power comes from the logic of the laws themselves.
Durkheim is a little different because his ideas on mechanical and organic solidarity are a little less specific and include some economic elements. Mechanical Solidarity:
- Works in small scale societies without a lot of people
- There are not a lot of different types of jobs
- People operate more independently
- Religion plays a bigger part
- Strict rule with harsh punishments
- The individual is downplayed compared to the society as a whole.
- Large societies with more people
- Jobs are specialized
- Because of specialization, people depend more on each other
- Religion plays a smaller part
- Restitution over punishment
- The individuality of people is valued
As you can see, both men are talking about how soc

Railway operators are replacing rural Japan's diesel-guzzling trains with new battery-powered rolling stock, taking advantage of the low-maintenance, environmentally friendly modern technology to cut costs and emissions.
East Japan Railway Co. began using battery-powered trains on the Oga Line in Akita Prefecture, northeastern Japan, in March, following a similar change on the nonelectrified Karasuyama Line in Tochigi Prefecture. Kyushu Railway Co. has also been using battery-powered trains on a nonelectrified section of the Chikuho Line in Fukuoka Prefecture in southwestern Japan.
Battery-powered trains reduce carbon dioxide emissions by 60 percent compared to diesel engine trains and require lower operational costs because they have no transmissions or engines which are made up of many moving parts and require constant upkeep.
A high school girl who uses the line in Akita for commuting said the battery cars are "cleaner and quieter" than diesel oil-fueled trains. Riding on them is "more enjoyable," she added.
Locals are hoping that the positive image of battery-powered trains would also attract more tourists to the region.
Of the Japan Railway group lines that stretch around 20,000 kilometers across the country, 40 percent are not electrified, meaning that on those sections, diesel- or battery-powered rolling stock are

One in 10 children with HIV have a'monkey-like' immune system that protects them from developing AIDS.
Experts say that this may lead to new immune-based therapies for the deadly infection.
HIV infection in children leads to the death of 60 percent of them before two and a half years of age. The same infection in the monkeys is not deadly.
HIV eventually wipes out the immune system, making the body vulnerable to other infections and leading to the development of AIDS.
The study by researchers, including those from University of Oxford in the UK, was conducted on 170 children who had HIV in South Africa. These children never had an

At inception, most devices are created with convenience and fun in mind, not all of the ‘what-ifs’ behind security vulnerabilities. This leads to many security vulnerabilities in the devices, which of course are exploited by hackers.
Gulf Breeze, FL (PRWEB) February 13, 2017
Botnets are making malware and spam campaigns more accessible than ever, noted AppRiver in its 2016 Global Security Report. Botnets’ range is considered to be primarily behind the escalation in malware activity—which clocked in at 15.5 billion malicious emails and 30.4 billion spam emails during 2016. The report also includes metrics from Web-borne threats, reporting an average of 40 million unique threats daily throughout the second quarter.
The report notes that in addition to traditional hardware like personal computers, the Internet of Things (IoT) delivers a new catalogue of devices that can be hacked for nefarious purposes. Smart watches, mobile phones, and smart assistants offer botnets millions of more devices that can be used to deliver their malware campaigns, or even to gather data on unfortunate consumers.
“When Mirai was used to take down Dyn last year, it cast a light on the lack of security protecting IoT devices,” said Troy Gill, manager of security research, AppRiver. “At inception, most devices are created with convenience and fun in mind, not all of the ‘what-ifs’ behind security vulnerabilities. This leads to many security vulnerabilities in the devices, which of course are exploited by hackers.”
The report also includes predictions for 2017, including:
- Acts of cyber aggression will become the new front lines between nation states
- Mobile malware will become a household name
- IoT botnets will continue to wreak havoc
- Ransomware will continue to be the most prolific threat on the Web
- New legislation will be passed to give more investigative powers to law enforcement
To prevent malware attacks, AppRiver recommends organizations have the following systems in place:
- Antispam and antivirus solutions, including protection against Web-borne malware
- Routine, mandatory software updates so that known vulnerabilities are patched
- Double authentication procedures as a safeguard against “whaling” and other highly targeted attacks
- Formal security policies and ongoing training to keep employees up to date and aware of their individual role in protecting company networks
AppRiver has included more detail on these attacks and statistics within its Global Security Report.

LITTLE BUFFALO, ALBERTA — It has been eight years since a provincial government in search of oil plowed a gravel road into the northern Alberta wilderness and yanked a tiny, isolated band of Indians into the 20th Century

LITTLE BUFFALO, ALBERTA — It has been eight years since a provincial government in search of oil plowed a gravel road into the northern Alberta wilderness and yanked a tiny, isolated band of Indians into the 20th Century.
The Indians, who had been one of Canada`s last aboriginal bands untouched by the outside world, aren`t sure how much longer they can last.
``If we are not too far gone yet,`` said Bernard Ominayak, chief of the Lubicon Lake band, ``it will only be a short while until we get there.``
Surrounded by huge jackpumps planted in the forest where they used to hunt, subsisting on welfare they never before needed, confounded by perplexing new social problems such as alcoholism and their first suicide in memory, the Lubicons are joined in what they say is a last pitched battle for survival against both the federal and provincial governments.
The Lubicons, a band of fewer than 400 Cree Indians who take their name from the nearby lake, are seeking to protect what`s left of their ancestral hunting grounds from further oil exploration.
The marshy, oil-rich land, owned by Alberta but promised to the Lubicons nearly 50 years ago, was all but inaccessible until the completion of the provincial road in 1979. It is now peppered with oil rigs, pumps and pipelines.
The Indians want clear title to a reservation here, and they want help in setting up new enterprises, possibly agriculture or ranching, to replace the hunting and trapping they fear has been destroyed forever by the oil drilling. Both levels of government continue to resist their requests.
The conflict is likely to cause increasing embarrassment for the Canadian government, which considers itself a world leader in humanitarian causes. To publicize their cause, the Lubicons have called for an international boycott of next winter`s Olympic Games in Calgary. While they don`t expect to halt the games, their efforts are showing a few small signs of success.
Moreover, native Indian leaders say, the plight of the Lubicons underscores Canada`s spotty record of dealings with its half-million native people, whose profound social problems and unresolved land claims continue to stab at the conscience of the nation.
Despite increased government social spending, Canada`s 592 Indian bands suffer 2 1/2 times the unemployment rate of the rest of the country, earn only two-thirds of the average national income and complete only half the average schooling. Their health is poorer, their life expectancy shorter and their infant mortality rates higher than the rest of the country.
What strikes many who have investigated the Lubicons` case is the apparent validity of their claim and the imminent danger to the community`s future if they do not get a reservation and an infusion of help soon.
``The urgency and inequity of the (Lubicon) band`s situation cannot be denied,`` said E. Davie Fulton, a nationally respected former minister of justice and British Columbia Supreme Court judge who was commissioned by the federal Department of Indian Affairs in 1985 to investigate the Lubicon case. His report, delivered last year and generally supportive of the Lubicons, has yet to be acted upon.
``I know of no other comparable situation,`` Fulton said in a recent interview, ``where a demonstrably justifiable claim has been ignored, frustrated, and the people subjected to unconscionable pressure by developers and governments. If it`s allowed to drag on much longer, they can`t continue to exist.``
The World Council of Churches also sent an investigative team to Little Buffalo. They returned to report that the Lubicons were threatened with
Yet the federal and Alberta governments, mired in years of paper-shuffling and conflicting interests, have been unable to reach agreement with the Lubicons over how much land they should get and what oil and mineral rights they are entitled to.
The problem persists because the Lubicons were essentially forgotten for so long that it became inconvenient to recognize them.
In 1939, the federal government sent a census-taker into the wilderness to count the Lubicons, and a year later they were promised a reservation, to be set aside on land owned by the province.
But no land survey was ever completed, and over the years, through succeeding bureaucracies, the promise was forgotten. Isolated as they were, the Lubicons were subsequently left out of important treaty and land-claim negotiations the federal government conducted with most of Alberta`s Indians. All the while, Alberta proceeded with its plans to open up to exploration what it suspected was an oil-rich region.
In 1979, the new provincial road finally penetrated the nearly impassable wilderness, defying the marshes that had so effectively shielded the Lubicons from outsiders.
For the first time, the Little Buffalo Indian settlement at Lubicon Lake was connected to the nearest town, Peace River, about 75 miles to the southwest. The oil companies

This brochure intends to serve two purposes:
1) Primarily, by guiding the reader through the process step by step, it may help the beginner develop an understanding of the complexities, pitfalls and mysteries of daguerreotypy. Warning: Do not use this brochure to actually attempt the making of a daguerreotype. The chemical procedure is far too dangerous for the incomplete information provided here. It deals with the physical manipulations and timing more than the chemistry of the process to give the reader a general feeling rather than a highly technical demonstration. Through review, using pieces only contemporary to the period, the advanced observer may develop a better understanding of how the craft affected the art. Thus, this pictorial instruction manual is offered for step by step making of a daguerreotype, utilizing only the finest examples of vintage equipment from the 1840s and the 1850s.
2) Through the photographs and information presented in this brochure, the reader will be able to identify and perhaps even rescue early equipment that might otherwise have been lost or forgotten. The very tools used for creating daguerreotypes are sculptural art in themselves and should be preserved and cherished along with the fascinating images they helped create.
It can be divided into many steps. In the interest of simplicity, both in this brochure and for display purposes, we chose to use five basic steps.
STEP I: PREPARING THE PLATE (20 to 25 minutes)
By far the most time consuming and labor intensive of the five-step process.
1) Remove a plate from the plate box (a).
2) If not pre-crimped in manufacture, use plate bender (b) to turn down edges. This takes less than a minute. Perfectly flat plates (c) were produced in the early years. Later, they were pre-bent at the edges (d) to aid insertion in a plate vice (i).
3) Remove buffing stick (e) from storage or warming box (f). Only one shown in this illustration, but each polishing agent gets its own buffer.
4) Vigorously scour the crimped plate (d) with powdered rotten stone (not illustrated) to remove surface imperfections.
5) Rub chalk rouge (g) on deerskin side of buffing stick (e).
6) Much more common was powdered rouge (h). Sprinkle on buffing stick and rub powder into surface of the hide (e).
7) Install plate in Benedictís plate holder (i), one of many gadgets sold commercially for securing the plate while buffing.
8) The entire assembly is clamped onto a wooden table vise (j). The vise is fastened to the table or bench. Now polish or buff the plate (always in the horizontal direction of what will be the finished image) for about 20 minutes to get a perfect mirror finish. The use of a treadle driven buffing wheel could measurably shorted the time of this step.
9) Lime from these bottles (k) is used to bed or cradle the bromine in the bottom of the glass tray which is inside the second coating box (n).
10) Insert buffed plate (m), face down in the sliding cover which is double the length of the box, and slide the plate into position over box containing iodine (l). When the plate turns light yellow, (usually about 15 to 25 seconds) remove from this box. The iodine stays good for years when kept in its sealed coating box so it is always ready to be used.
11) Move the plate (m) to the bromine box (n) and slide into position for approximately 5 to 10 seconds till the plate turns rose colored. When this takes over 15 seconds, the bromine (or quick stuff) has weakened and a pinch more should be added to freshen up the existing chemical. It will then stay potent for months.
12) Now in darkness, return plate to the iodine box (l) for a few seconds. This completes the coating, and you now have a properly sensitized plate.
13) Insert polished and sensitized plate in a plateholder (o) and close dark-slide, (shown partially open in this illustration).
14) All polishing except for the quick final buff of the plate with lampblack (not illustrated) is done in advance so the sitter can enter the studio and receive a finished likeness in less than thirty minutes!
STEP II: TAKING THE EXPOSURE (2 to 8 minutes)
1) Place the camera (a) on a tr

Ashwagandha - also known as Indian Winter Cherry has the Botanical name Withania Somnifera -It is a shrub belonging to Solanace family. It is grown in the western India, Gujarat, MP, Punjab and in Himalayas.
Ashwagandha gets its name because its roots have the odor of horse. (Ashwa = horse, gandha = odor). It is called by another name Varaha karni because its leaves resemble pig’s ear.
Ashwagandha has light (laghu) and sticky (snigdha) properties, bitter and sweet taste. On digestion the sweet taste dominates. The main part used is root of this herb.
Medicinal properties of Ashwagandha
The various medicinal properties of ashwagandha is attributed to compounds known as withanolides which are present in it.
Ashwagandha is used as an adaptogen (as it enhances endurance), rejuvenating tonic and sedative. Hence many herbalists refer this herb as Indian ginseng.
Effects on mind: As it balances vata and kapha, it improves memory, counteracts the effects of stress and calms mind. It has an ability to relieve stress. It acts as sedative. Stressed patients with insomnia are benefited by this herb.
This herb can be used in Alzheimer’s disease, memory loss and insomnia.
Effects on general health : It acts as balya and strengthens the body. Generally, ashwagandha stimulates the immune system and strengthens it. It increases body energy level.
Convalescent patients’ gain more energy and can spring back to normal routine quicker when this herb’s preparations are used after illness.
The immediate relapse of disease is prevented on use of Ashwagandha. This supports HIV patients by strengthening their immune system.
Anti-inflammatory properties: It has anti-inflammatory properties and has been successfully used in adjuvant therapy for arthritis. It reduces inflammation of joints and eases movements.
Effects on digestive system: Ashwagandha increases appetite. It normalizes digestion and bowel movements.
Effects on reproductive system: This magic herb increases shukra dhatu, sperm count and sperm motility. It increases libido and known as best Vajikara dravya (aphrodisiac)
It is also used as uterine tonic and to enhance female libido.
Ashwagandha retards ageing process when used as rasayana (rejuvenating preparation).
It reduces hypertension and also acts as diuretic.
Effects on pregnant woman: Ashwagandha is very effective in conditions like habitual abortion, threatened abortion. It stabilizes pregnancy and balances harmones which stabilize pregnancy.
Usefull preparations of Ashwagandha:
1. A paste of ashwagandha leaves when applied on a local inflammation acts as anti inflammatory.
2. The herbal massage oil which includes this herb is useful in many conditions like paralysis, epilepsy, sleeplessness etc.
3. The preparation of Ashwagandha which is processed with ghee, sugar and honey is a very good aphrodisiac and increases semen quantity, sperm count and motility. It is effectively used in Erectile dysfunction, low libido and premature ejaculation.
4 Ashwagandha roots when used regularly helps to improve the conditions like emaciation of children, senile debility, rheumatism, in all cases of general debility, nervous exhaustion, brain-fag, low of memory, loss of muscular energy and spermatorrhoea. It increases body energy and vigor. It helps to rebuild the body system which is worn out due to chronic diseases like syphilis, rheumatism etc. It also replenishes the lowered energy of body due to over-work, mental exertion thus preventing early ageing.
5 Ashwagandha when used regularly, is very useful in emaciated children. It increases body weight and body energy.
6 Regular use of ashwagandha helps to reduce blood sugar and cholesterol levels.
7 Fine powder of ashwagandha well mixed with oil is very use full in many skin conditions.
8 Ashwagandha also acts as galactogogue and thickens the milk when given to nursing mothers.

The central theme of The School for Field Studies (SFS) Panama study abroad program is “islands as a delicate system,” with emphasis on the resources of Panama’s spectacular coastal and marine environments. Students will explore several key interfaces: human and natural systems, terrestrial and marine ecosystems, and conservation and development. The goal of this undergraduate study abroad program is to assess the state of the archipelago’s fragile natural habitats, define the main environmental issues, and understand the community goals in natural resource management. Our ultimate goal is to help islanders maintain balance and harmony between people and nature in this fragile ecosystem.

Scientists puzzled by massive North American starfish deaths
Scientists are struggling to find the cause of a disease that is killing off numerous species of starfish on both the Pacific and Atlantic coasts of North America, dispatching the five-armed creatures in a particularly gruesome way.
Researchers said on Thursday they have ruled out some possible culprits including fungi, some parasites and certain other microorganisms and are taking a hard look at whether viruses or bacteria may be to blame.
The starfish, also called sea stars, are being obliterated by an unexplained wasting disease that causes white lesions to appear before the animal’s body sags and ruptures and it spills out its internal organs.
“The magnitude of it is very concerning. There’s the potential that some of these species could actually go extinct,” said Cornell University ecologist Drew Harvell, one of the scientists involved in the loosely organized search for a cause.
Harvell said she is concerned because the mysterious pathogen is affecting 18 different West Coast species along their entire range. Pathogens that affect an animal’s range in such a way like a fungus that has targeted frogs can be particularly damaging, she said.
The disease appeared last year and is showing no indication of abating. “I wish we had a sign that it was petering out, but believe me it definitely is not,” Harvell said.
The scientists seem to have more questions than answers.
“What is it that has caused this? Where did it come from? If it’s exotic, how did it get here? Is it something that’s likely to be repeated?” asked Pete Raimondi, chairman of the Department of Ecology and Evolutionary Biology at the University of California, Santa Cruz.
Raimondi expressed concern that the disease that is killing the starfish could be a harbinger of bad things to come for other marine species. “This is a really difficult disease in lots of ways because it’s very virulent,” Raimondi said.
The researchers noted that starfish were the victims of previous diseases in past decades that reduced their numbers, but the current one is more serious.
The scientists are wondering whether the starfish have been infected by a virus, bacterium or something else unwittingly imported to the region or whether a pathogen already present somehow became more dangerous, Raimondi added.
Scientists prefer to call the animal a sea star rather than a starfish because these marine creatures are not fish but rather echinoderms, cousins of sand dollars, sea cucumbers and sea urchins. Most have five arms, although some have many more.
They are remarkably durable creatures, and when healthy are able to regenerate lost limbs. They are predators and use suction to pull shells apart to get at the soft body inside. When the shells are pried opened, the starfish pushes its stomach out of its body and into the prey, secreting enzymes that digest the victim’s soft body parts.
They are significant predators in their ecosystems, th

Seniors are at increased risk of infectious diseases due to a decline of their immune function with age (also called immunosenescence). Infectious diseases, especially when chronic diseases are present, can disrupt a fragile equilibrium in seniors and lead to functional decline and loss of autonomy.

quotes easily describe conditions in slums and squatter
settlements in any city in any developing country today,
but, in fact, they were written over a hundred years ago
by Jacob August Riis. He emigrated to North America from
Denmark in 1870, and when Riis finally managed to get
a job as a police reporter, he described the squalor and
humiliation he experienced in the slums and tenements
of New York. Riis went onto to become a leading social
reformer, and his landmark book published in 1890, 'How
the other half lives', inspired New Yorkers, including
Theodore Roosevelt, to initiate long needed reforms in
providing housing and shelter for the poor.
is not the only journalist to have given a voice to the
homeless and to have fought for their right to better
housing. In the 19th century, industrialization in Europe
and America led to rapid urbanization. The population
of London went from about 800,000 in 1800 to over 6.5
million in 1900; during the same period, Paris grew from
one-half to over 3 million; and by 1900 New York's population
had swelled to 4.2 million. This explosion meant that
the poor lived in dark, airless and unsanitary tenements,
often without windows, where they were regularly exploited
by rapacious landlords and politicians. With the advent
of the mass media, the cause of the poor was taken up
by many illustrious journalists and authors. Dickens,
Mayhew and Zola, amongst others, wrote articles and novels
that revealed to their readers the appalling conditions
in human settlements. Such writers were instrumental in
changing the policies of their time.
over a hundred years later, the task is not over. At the
start of the urban millennium, when over half of humanity
will live in cities and towns, there is a pressing need
for the public to be made aware of the problems of urbanization.
Though rates of urbanization in the developed world and
in Latin America and the Caribbean have stabilized at
around 75 per cent or above, Africa and Asia -- which
are both still predominantly rural -- face an explosive
demographic shift, as their urban populations surge from
about 35 per cent to over 50 per cent in the next 30 years.
It is estimated that, between 1990 and 1995 alone, the
cities in the developing world grew by 263 million people
-- the equivalent of another Los Angeles every three months.
Every day there are an additional 180,000 people in cities
and towns all over the world.
process of urbanization must be viewed against the backdrop
of globalization and the industrialization of the developing
world. In today's international economy, cities are forced
to compete with one another to attract capital. Local
authorities everywhere are investing heavily in infrastructure
and housing to attract multi-national investment. But
evidence suggests that, even in cities like New York and
London, globalization has led to an increasing polarization
between the rich and the poor.
the developing world, where migrants continue to flock
to urban areas for jobs, the situation is worse. Over
50 per cent of the population in cities in the developing
world live in unplanned, spontaneous settlements and slums.
It is also estimated that at least 36 per cent of all
households, and 41 per cent of all woman-headed households,
live below the locally-defined poverty level. Though it
is difficult to estimate, it appears that the urbanization
and feminization of poverty have resulted in almost a
billion poor people living in urban areas without adequate
shelter and basic services.
just as a century ago, there is a need for journalists
to inform the public about the living conditions of the
urban poor; to ask why such conditions continue; and to
exchange ideas on possible solutions and proven best practices.

Assembly that will be held in New York from 6 to 8 June

“Where is the wisdom we have lost in knowledge? Where is the knowledge we have lost in information?” -T. S. Eliot (1888-1965)
We hear a lot about this being the information age. Technology is making information available at warp speed across the globe. We are creating data bases for all kinds of things. A Google search gives me information concerning every conceivable area of interest. All good. Let’s remember, the information may be accurate or inaccurate, complete or incomplete. At this point, it is simply raw information.
What is knowledge and how does information become knowledge? Here’s one definition of knowledge: facts, information, and skills acquired by a person through experience or education; the theoretical or practical understanding of a subject.
OK. Now, how do I gain knowledge, as opposed to a falsehood? On this post I am attempting to transfer knowledge I’ve gained to you. How do you know it’s true? Am I to be believed? So, you can see turning information into knowledge is tricky.
So far in this process we have raw information – not truth in any absolute sense – just raw information. It gets picked up, absorbed by the mind of a human being who takes the raw information and transforms it through some unknown alchemical process into knowledge – something the human being knows.
Garbage in, garbage out! In our world where we are inundated with information from so many sources, our first task is to question the accuracy or validity of the information. If our raw information is flawed, our knowledge is flawed.
Let’s assume we have good information and our mysterious, alchemical brain process has combined it with other good information and we have transformed it into knowledge, untainted by our own biases? That’s all a stretch, b

they lose their globular tips and become more or less worn with age. Issuing from the mouth of the gall, these young lice scatter over the vine, most of them finding their way to the tender terminal leaves, where they settle in the downy bed which the tomentose nature of these leaves affords, and commence pumping up and appropriating the sap. The tongue-sheath is blunt and heavy, but the tongue proper––consisting of three brown, elastic, and wiry filaments, which, united, make so fine a thread as scarcely to be visible with the strongest microscope––is sharp, and easily run under the parenchyma of the leaf. Its puncture causes a curious change in the tissues of the leaf, the

growth being so stimulated that the under side bulges and thickens, while the down on the upper side increases in a circle around the louse, and finally hides and covers it as it recedes more and more within the deepening cavity. Sometimes the lice are so crowded that two occupy the same gall. If, from the premature death of the louse, or other cause, the gall becomes abortive before being completed, then the circle of thickened down or fuzz enlarges with the expansion of the leaf, and remains (Fig. 2, c) to tell the tale of the futile effort. Otherwise, in a few days the gall is formed, and the inheld louse, which, while eating its way into house and home, was also growing apace, begins a parthenogenetic maternity by the deposition of fertile eggs, as her immediate parent had done before. She increases in bulk with pregnancy, and one egg follows another in quick succession, until the gall is crowded. The mother dies and shrivels, and the young, as they hatch, issue and found new galls. This process continues during the summer until the fifth or sixth generation. Every egg brings forth a fertile female, which soon becomes wonderfully prolific. The

HAKONE – According to the Japanese Meteorological Agency, a series of small earthquakes that have occurred since April 26th and have been steadily increasing could account for the smoke currently billowing around Mount Hakone.
On May 6th, three separate earthquakes occurred around Hakone city, which is the site of a number of hot springs. According to officials, high temperatures underground and volcanic gas have been reported.
Officials have also upped the level of caution people in the area should take bringing it up to level 2 of a possible 5 levels of danger. At level 3 people are asked to stay in their homes, at level 4 people are asked to prepare to leave, and at level 5 people are told to evacuate the surrounding area.
Several witnesses have seen smoke billowing out of Mount Hakone in the area and took to Twitter to post photos.
Most reports state that this is not an emergency situation, but ask people to take steps to be ready for any eventuality.
Currently part of route 734, which is a road that leads around Hakone city, is currently closed and the Hakone-ropeway, a popular tourist destination, has stopped service.
The Great East Japan Earthquake in 2011 caused some earthquakes near to Mount Hakone; however, the last large-scale volcanic eruption at the mountain occurred over 3,000 years ago.
Hakoneyama is actually considered to be one of the most active volcanoes in Japan. One of the more recent near eruptions occurred in the 12th century where a huge steam explosion was reported.
So if Mount Hakone erupts how much more dangerous would it be than Mount Fuji?
There is a possibility that the damage could spread toward Tohoku and Chubu areas. As well, if few centimetres of volcanic ashes falls in a major city centre like Tokyo it could cause blackouts and traffic jams.

There is far more to creating a smile then just the colour of the teeth. The following will help you become an expert at analysing before and after images of teeth. When creating a smile the shape and position of teeth is based on symmetry, parallelism and mirror imaging. These contemporary concepts of aesthetics are individualised for each persons smile. Below is a brief outline adapted from an article by Dr Geoff Knight written almost 10 years ago but still relevant today, of the initial landmarks we use to decide how to design your smile and shape your crowns, veneers and white fillings.
Mid-line – The mid-line between the top front two teeth is in the middle of the smile and vertical. Shifts of more than a couple of millimetres can detract from the symmetry of the smile. (Red Line)
Lateral Emergence Profile – The sides of the teeth are parallel and mirror images of each other with a slight inclination towards the midline. (Pink Lines)
Teeth Length, Width Proportions – We call this the golden proportions where the lengths and widths of the teeth are in a certain proportion (the same proportions were used to build the columns of the Parthenon in Greece)
Smile Line – The tips of the upper teeth, known as the smile line runs parallel with the lower lip. (Blue Line)
Gingival Line – The gingival line, where the gum meets the teeth, runs parallel with the smile line but with slightly less curvature. This is critical if your gums are very visible when you smile. (Green Line)
Anterior Emergence Profile – The side profile of the teeth is parallel with the side facial profile. So when you look from the side of the face, they follow the natural curve of the face.
Incisor Embrasures – The size of the incisal embrasures (Grey Triangles) and the angles of the incisal embrasures (Yellow Lines) increase from the midline outwards, they should be parallel and mirror each other.
So next time you see a smile that looks amazing like Megans, or indeed your own smile, it will most likely follow these rules.

“These brave Belgian people have nobly done their share in opposing the German aggression, and let us do our best to show our gratitude.”
Councillor C.W. Emson, Mayor of Tunbridge Wells, in October 1914
That Tunbridge Wells had its own “Belgian Colony” during the First World War is a largely unknown part of the town’s history, even though after the war members of the town’s Refugees Committee, notably its former Mayor Councillor C.W. Emson and social pioneer Amelia Scott, were decorated by the King and Queen of the Belgians in recognition of their work.
As the crisis unfolded in late August 1914, Tunbridge Wells was quick to respond, and individuals came forward to offer accommodation and help.
One such offer came in early September, when Mr and Mrs Johnstone of Burrswood, Groombridge offered Clayton’s Farmhouse in Ashurst and formed a small committee to prepare for arrivals. By the end of the month the first group of men, women, and children had arrived, many of them from the village of Herent near Leuven, bringing tales of the horrors they had seen and experienced.

By this time there was a War Refugees Committee (WRC) up and running in London, and a War Relief Committee in Folkestone, and the Mayors of all large Boroughs outside London, as well as the chairmen of County Councils and large Urban District Councils, were invited to form local committees to liaise with the WRC regarding the allocation, reception and maintenance of all refugees within their area.
Letter from Mayor Emson to the Secretary of the Belgian War Relief Committee in Folkestone, published in both the Kent and Sussex Courier and the Tunbridge Wells Advertiser on Friday 16th October 1914 (Source: British Newspaper Archive)
The Mayor of Tunbridge Wells, Councillor Charles Whitbourn Emson, did just that, and chaired the Committee throughout the war, continuing with the role when he was replaced as Mayor in November 1917. The Committee worked tirelessly to make the refugees welcome, and by the end of October 1914 nearly 100 refugees had been placed in accommodation by the Committee. In total some 297 destitute people – 78 men, 144 women, 35 boys and 40 girls – found a safe haven here in Tunbridge Wells, though the most at any one time was 96 adults and 35 children. (This number was augmented by those who were able to support themselves or who stayed with friends.)
After the war, members of the Tunbridge Wells Refugees Committee, notably Councillor C.W. Emson and Amelia Scott, were decorated by the King and Queen of the Belgians in recognition of their work on behalf of the Belgian refugees in Tunbridge Wells.
The Mayor also opened a Local Fund for Belgian Refugees and in the months that followed, gifts of money, furniture and even homes, poured in, and lists appeared in the Courier each week of those who had contributed.
Some arrived with nothing, some did have some money and were able to support themselves, at least for the first few months; all needed clothing and basic necessities. Houses were rented and furnished, schools found for the children, English lessons given, a Belgian Shop opened on the High Street, and even a Belgian School in Spring 1918. Local doctors gave their services free of charge, and the Kosmos cinema and Opera House provided free entry to shows.

There were births, marriages, and deaths among the community, and St Augustine’s Catholic church was the scene of several high-profile funerals, as well as annual national celebrations.
The Belgians of Tunbridge Wells had their own Club, the “Club Albert”, and were given use of a room at the Constitutional Club on Calverley Road. Its Committee met regularly, hosted social events and information meetings for the Belgians of the district.
The newspapers published lists of refugees’ names to enable friends and families to discover their whereabouts – many families became separated as they fled, some were never reunited. The Mayor regularly used the pages of the Courier to ask for more help and funds for the refugee relief work.
As the war dragged on, refugees began to leave Tunbridge Wells, some went to the Front to fight, some moved to other districts to take up employment, others returned home, others moved on to France – a Belgian Repatriation Fund was set up as early as November 1915 – but many stayed until the war’s end, and when the Armistice was declared in November 1918, members of the Belgian colony joined the great celebratory parade wearing their Belgian colours of gold, red and black with what the Courier described as “smiling pride”, and bearing a banner declaring “Long live England. We thank you all.”
By the end of May 1919, when the Borough Refugees Committee met for the last time, all the Belgians had returned, most under the National Scheme by which free passage was provided by t

Seals have helped gather information on some of the harshest environments on the planet, using technology designed by scientists at the University of St Andrews.
The resulting data – gathered from remote, icy seas over the last decade – will be made freely available to scientists around the world as part of a new data portal launched today (Monday 1 June 2015).
The MEOP (Marine Mammals Exploring the Oceans Pole-to-pole) portal offers – for the first time – data on parts of the planet virtually inaccessible to man. By tapping into the natural habitat of seals, such as ice-bound polar regions, researchers have been able to build up a detailed picture of those areas currently very difficult for humans to visit and monitor.
Thanks to sensors designed and made at the Sea Mammal Research Unit at the University of St Andrews, teams of experts around the globe have been able to collect information on the conditions of the world's most remote oceans.
Since 2004, a small army of seals equipped with the sensors has produced nearly 400,000 environmental profiles, resulting in one of the world's largest oceanographic database for polar oceans.
Mike Fedak, a Professor of Biology at the University of St Andrews, said, "The fact that animals have collected the data is an interesting innovation in ocean observation. But perhaps of more general importance is that data from these remote and inaccessible places now gives us a much clearer picture of the state of the world's oceans. We have since shown that data from these far-flung locations is critical to understanding the broader state of the Global Ocean."
The sensors – or 'tags' – are non-invasive (they fall off when the animal moults) and the only devices of their kind that can be attached to animals.
The tags sent information periodically back to researchers in short messages via satellites. Dr Lars Boehme, a Lecturer at the University of St Andrews, explained, "The information sent back to us gives us details about the seal's immediate physical environment. It's like tweeting."
Data was decoded and processed back in St Andrews, before being shared with the consortium. Information was also relayed to the Met office and similar bodies across the world for use in weather forecasting.
Scientists around the globe – including St Andrews in Scotland and the British Antarctic Survey - did their own individual research using the data, before making it available for other scientists and climate researchers to use via the new portal.
The St-Andrews technology forms part of a global ocean observing system – including satellites - that diving marine animals such as seals are forming an essential component of.
Dr Boehme continued, "Changes in the polar oceans have global ramifications and a significant influence on weather and climate. Sustained observations are required to detect, interpret and respond to change and a strategic system of observations combining a range of platforms is critical in maintaining the flow of information.
"The new portal will make available all the data collected by animals up to now to the wider international scientific community and will import future animal platform data as well. This development is particularly timely as an increasing

A paper published online in Molecular Biology and Evolution claims to have “rigorous proof that [junk DNA was] added to DNA ‘late’ in the evolution of life on earth–after the formation of modern-sized genes, which contain instructions for making proteins” according to a press release from the National Institute of Standards and Technology, whose Center for Advanced Research in Biotechnology (CARB) was involved with the research (link)
The press release states:
Research from the CARB group appears to resolve a debate over the "early versus late" timing of the appearance of introns. Since introns were discovered in 1978, scientists have debated whether genes were born split (the "introns-early" view), or whether they became split after eukaryotic cells (the ones that gave rise to animals and their relatives) diverged from bacteria roughly 2 billion years ago (the "introns-late" view). Bacterial genomes lack introns. Although the study did not attempt to propose a function for introns, or determine whether they are beneficial or harmful, the results appear to rule out the "introns-early" view. The CARB analysis shows that the probability of a modern intron's presence in an ancestral gene common to the genes studied is roughly 1 percent, indicating that the vast majority of today's introns appeared subsequent to the origin of the genes. This conclusion is supported by the findings regarding placement patterns for introns within genes. It long has been observed that, in the sequences of nitrogen-containing compounds that make up our DNA genomes, introns prefer some sites more than others. The CARB study indicates that these preferences are side effects of late-stage intron gain, rather than side effects of intron-mediated gene formation.

In vitro fertilization, or IVF, is the fertilization of the egg and sperm outside the body. At Arizona Center for Reproductive Endocrinology and Infertility, we use IVF to help couples who have been unable to conceive after a long period of trying, to finally achieve pregnancy.
IVF treatment was originally developed in 1978 to help women who had issues conceiving due to blocked fallopian tubes. Today, nearly 40 years later, it’s been proven as a very safe and cost-effective technology to help women get pregnant who wouldn’t be able to any other way. IVF is an effective solution to women above the age of 40 who have problems conceiving due to age.
The IVF Treatment Process
Women produce many eggs every month, but they only ovulate one—so many eggs go unused at the end of every month. The number of eggs a woman produces is partially dependent on a woman’s age; a younger woman can sometimes produce 20-30 eggs in a month. In vitro is a simple method, using hormones that the body usually manufactures and produces, to retrieve all the eggs a woman develops during any given month.
During the process of taking the hormones, the patient comes in for a series of ultrasounds. The eggs are retrieved in the office during a safe and simple in-office process that uses the ultrasound. Then, the eggs are paired with the man’s sperm (provided through a specimen) and fertilized in vitro, literally meaning in glass, in the laboratory.
After fertilization, we monitor and test the development and health of the embryos. Because of today’s technologies, we are able to test the embryos to determine not only the sex of the baby, but if the baby will have any chromosomal abnormalities, such as down syndrome, or genetic abnormalities, like cystic fibrosis. We can also screen the embryos to make sure they are developing normally and are chromosomally competent, which dramatically cuts down the probability of a miscarriage.
Once the embryos are developed, we re-insert them back into the woman’s uterus and then follow up with the patient in two weeks to determine if she is pregnant. Overall, it’s a simple procedure that’s very similar to a routine pap smear.
6 Things to Know About IVF
The most important thing to know about IVF is that the chance of pregnancy is very high with the process. But there are five other things patients should know about in vitro.
- In general, about two-thirds of patients will get pregnant on the first try using in vitro. Oftentimes, the in vitro process will provide us with enough embryos for two or three attempts. So if you factor in the fact that a patient might have three tries per treatment, the overall chance of getting pregnant approaches 100 percent.
- Success rates are very dependent on the patient’s age. As women get older, they have fewer healthy eggs. That’s why it’s more difficult, in general, for women to get pregnant as they get older.
- There is the possibility of birthing twins. If we place more than one developing embryo in the uterus, having twins is always a possibility. However, the chances of having multiple pregnancies (like triplets and quadruplets) are minimal to non-existent.
- Babies born from in vitro are just as healthy as babies born naturally. More than 1 million babies have been born throughout the world through in vitro fertilization. And, because of genetic testing, babies born through IVF may be even more likely to be healthy overall than babies born naturally.
- The procedure is safe and risk-free for the moms-to-be. All of our patients who have gone through the in vitro process would do it again if they had to, because in the end, they’ve given birth to a bundle of joy. The procedure is painless, and in the end, having a baby is the best gift for our patients.
Having difficulty conceiving naturally can be an incredible burden and extremely stressful; the in vitro process takes some of that stress away by offering women and couples the chance to finally have a baby.

The Supermarine Sea Urchin was an unbuilt British racing biplane flying boat designed by the Supermarine Aviation Works to compete in the 1924 Schneider Trophy. It was to be a single seat biplane, powered by a Rolls-Royce Condor V-12 water-cooled engine buried in the fuselage, driving a pusher propeller mounted on the upper wing via geared shafts. It was abandoned without being built owing to problems with the engine and the transmission required to drive the propeller.

This style of programming is very common in stack-based languages, or rather in concatenative languages in general.
:square dup * # def square(x): return x*x
:squares [square] map # def squares(l): return [square(x) for x in l]
# using equivalent of first class func
:squares [dup *] map # using anonymous func def
[1 2 3] squares ==> [1 4 9]
In the latter form, the func literal expression -- often called 'quotation' because it 'quotes' code without executing it -- can be whatever and as long as needed, which is easy due to the linear style of stack-based programming. "Higher order" functions like map, called combinators, are very frequent and (unlike in other paradigms) make the code clearer. But they are not really higher order functions, rather they take several kinds of data as input, one of which happens to be code that will be 'unquoted', i.e. run -- closer to Lisp's eval.

The U.S mint is releasing a set of new one-dollar coins, honoring the United States Presidents. One of the goals is to create an atmosphere for history with these, teaching when opportunity arises. The coins will arrive every three months presenting the Presidents in the order they held office.
The first coin bears the resemblance of George Washington, with Adams, Jefferson, and Madison rounding out 2007.
The Washington dollar will be the first such coin introduced since the debut of the Sacagawea dollar in January 2000. That coin, honoring the Shoshone woman who served as guide to Lewis and Clark, featured a gold tint to help differentiate it from the similarly sized U.S. quarter. More than a billion of the coins have been issued, the mint reports. [photopress:New_dollar_coin.jpg,thumb,right]
An earlier dollar honoring women’s rights activist Susan B. Anthony, minted 1979-81 and again in 1999, met with consumer resistance because it easily was confused with quarters. Nonetheless, more than 888 million of the coins were produced.
The new Washington coin, to be minted in a manganese-brass alloy, was designed by Joe Menna, a sculptor-engraver employed by the mint. Treasury Secretary John Snow approved the design last summer

21 Royal Circus, Edinburgh EH3 6TL
Robert Jameson was Edinburgh’s professor of natural history from 1804 to 1854. He was, like his predecessor John Walker, a mineralogist by training, having studied with the great German mineralogist Abraham Gottlob Werner in Freiberg. On his return to Edinburgh he became the most important champion of Werner’s neptunist theories in Britain. It was also through his edition of Georges Cuvier’s Theory of the Earth that the English-speaking world first became aware of the great French geologist’s catastrophist theories. Some scholars believe that he was also an early convert to the evolutionary interpretation of the history of life.

The first Anabaptist influence in Vienna was apparently brought by transient brothers on their way to and from Nikolsburg (situated 50 miles north of Vienna), where Anabaptism had shown a vigorous growth ever since Hubmaier and Glait led the movement (ca. 1526). Hans Hut, leaving Nikolsburg with Glait in early 1527, stopped in Vienna and held meetings (well known in Anabaptist history) at a house in the Kärntnerstrasse, where he is said to have baptized not fewer than fifty persons, among them Leonhard Schiemer. Discovery of the group by the authorities forced Hut to flee and seems to have led to the final dissolution of this budding congregation. A well-advertised threat of the harshly Catholic Ferdinand to tear down houses which harbored Anabaptists was not carried out, and it is known that the inn "Freisinger Hof" actually had Anabaptist guests after this.
Apparently some of the Austerlitz Brethren, led by Jacob Wideman, maintained a group in Vienna for a time, but little is known about them. However, Inquisition material shows that booksellers in Vienna were always in contact with Moravia and may have functioned as middlemen (DeWind). Hieronymus Käls, who was arrested with Michel Seifensieder and Hans Oberecker in Vienna on 8 January 1536, while en route to his brethren in Tyrol, reported in his second letter from prison, "We have learned that many pious Christian hearts have nobly testified the truth of the Lord here in Vienna, brothers and sisters." Among these was Jacob Wideman, whom Käls mentioned expressly as a martyr (1535). Leonhard Lochmaier, likewise en route to Tyrol from Moravia, was arrested with Jörg Fasser in Neudorf, south of Vienna, and brought to trial in Mödling nearby, but they were soon miraculously freed. Oswald Glait was also arrested in Vienna in the fall of 1546, and having resisted all pressure to recant was drowned in the Danube at night. The last Anabaptist execution in Vienna was that of Hans Gurtzham in 1550.
A milder policy toward nonconformists came with the accession of Emperor Maximilian II in 1564, but this period soon came to an end when Jesuits settled in Vienna and with them the Counter Reformation set in. There is no further record of Anabaptists in Vienna, even not as transients.
After World War II numerous Mennonite refugees from Russia found their way to Austria through Rumania, Hungary, and Czechoslovakia, some of them (ca. 400 at the peak) settling in Vienna, where a few were still living in 1958. The Mennonite Central Committee began relief work in Austria in September 1946, with headquarters in Vienna, ministering to the general population as well as to Mennonit

Americans are eager to report that their country was settled, cultivated, and advanced by "rugged individuals." The "individual," in the American conception, is an independent and inventive agent, relatively autonomous and morally responsible to himself. A proliferation of specific propositions concerning "human nature" was derived from this ethnocentric premise. For example, a man was ideally allowed to voice his disagreement with the decisions and practices of the authorities, he was expected to choose the occupation of his preference and be self-supporting, and he was encouraged to follow his own convictions and beliefs. While these cultural propositions are still maintained, at least on the ideal level, in reality a considerable degree of dependency and conformity has developed. A number of regulations have been introduced, presumably guaranteeing security and consistency of economic well-being for all Americans; these include, for example, such institutions as Social Security, Medicare, obligatory retirement funds, and other similar measures. Critics call these measures "welfare state" practices and claim that freedom is no longer clearly tied to a social system of private property and passive government. In the opinion of many Americans, this trend threatens standards of individualism by unduly restricting personal determination, decisions, and choices.
In the industrial realm, modern technology and its efficiency have resulted in establishing norms and standards for production as well as consumption. The American emphasis on efficiency and expediency has always been of fascination to outside observers. The Germans coined the term Fordismus to describe the standardization, mass production, and "streamlined" efficiency of the American industry and business world, assuming that Ford represented the protoype of American productivity. In the course of this growing industrial efficiency and expediency, individualistic and creative participation in the production process has become greatly reduced for the vast majority of employees. There is even a question whether the product itself meets standards of individuality and uniqueness, since it has been mass-produced and is designed to suit the tastes of thousands of people.
American youth, on one hand, are brought up in the knowledge of American history, which includes many well-known and glorified examples of "rugged individualism," and are encouraged to emulate this "truly American" trait. On the other hand, however, American youth are constantly challenged to conform to national and patriotic standards requiring high degrees of conformity to majority opinion. Although these conflicting values have of course been a natural part of any era, they appear to have been unusually intense during the late 1960's when dissent and counterdissent concerning the war in South Vietnam ran high. Some of the basic questions that emerged for the sociological observer concerned the surprisingly widespread public opinion which perceived dissent not as an expression of independent individual thinking and believing but as subversive and "un-American" conduct. If one studies, in addition, reliable national survey data that captures the mood of contemporary American teen-agers, one is inclined to conclude that the original "rugged individualism" is now juxtaposed with a strong emphasis on conformity. This emphasis stood out in survey data published by the Purdue University opinion research center, showing that "more than 50 per cent [of the teen-agers] think the large mass of us in the United States simply aren't capable of deciding for ourselves what's right and what's wrong."
It appears then that there is a serious discrepancy between the American ideal of "rugged individualism" and its actual implementation. A teen-ager has to learn carefully that this blueprint for American individualism is not generalizable and that there are definite areas of limitations and prohibitions. The fact of non-generalizability destroys the simplicity and predictability of always responding to the same cue in identical or similar ways, thereby complicating the learning process and rendering the behavioral blueprint ambiguous and situational.

Possessing wealth, dominating others, and desiring fame are material values. Children develop their values by learning from adults. Materialism, an individualistic value, is harmful for the society and is a growing cause of concern. While many studies have been carried out on materialism, gratitude has recieved less attention from researchers. This study evaluated the effect of materialism and gratitude in adolescent schoolchildren. It found that gratitude is positively associated with higher academic performance, satisfaction in life, and social integration. Furthermore, students with higher gratitude are less likely to be envious or depressed.
Children form their attitudes and values based on inputs and influences from society. Exposure to materialistic individuals has a direct influence on children, encouraging them to acquire materialistic values. These values induce aspirations like the desire for wealth and fame. They promote greed for self-enhancement by seeking success and dominance over others. Materialism is related negatively with psychological well–being. Gratitude has the opposite effect. Teachers and parents are anxious about young people who seem to be more materialistic. This study evaluated values of materialism and gratitude, and their effect on the well–being of adolescents.
* The study involved 1,035 students from grades nine to 12 in a public high school in New York.
* Materialism was evaluated based on the Material Values Scale. The scale ranged from “1” (strongly disagree) to “5” (strongly agree).
* Gratitude was tested using three questionnaires, the Gratitude Questionnaire, the Gratitude, Resentment, and Appreciation Test (GRAT), and the Gratitude Adjective Checklist.
* The academic achievement of the participants was determined by their grade point average (GPA) in examinations.
* Satisfaction with life, envy, level of depression, and social integration were also estimated using questionnaires.
* There was a negative association between materialism and gratitude.
* Materialism was associated with lower academic achievement (GPA), higher envy, lower satisfaction in life, lesser social integration, and high self-consciousness.
* Gratitude was moderately associated with higher GPA and lower self-consciousness. It was strongly associated with life satisfaction and social integration.
* Females had higher levels of gratitude and lower levels of materialism than males.
* Materialism and gratitude were unrelated to age or ethnicity.
The study was based on students belonging to affluent socioeconomic groups. The findings could be different in other socioeconomic classes, since the drive for material possessions might be different in such groups. The study was limited to one school and therefore, it may not represent a large population. The conclusions were obtained from self-reports that could be biased.
Grateful adolescents obtain higher grades. They also are more socially integrated, and have higher levels of satisfaction in life. Such grateful students are less envious and depressed than their counterparts who display more materialism. It is possible that materialism produces difficulty in establishing warm relationships. A sense of gratitude may help people learn to enjoy the present. It will help them to achieve freedom from regrets and anxieties. Gratitude teaches that happiness does not depend on material possession. It also helps to create a network of caring people and contacts. Thus, emphasizing gratitude rather than material gains as a sign of success is important for the well–being of adolescents.

Ferns for Mississippi Gardens
Referred to as 'nature's lacework', ferns provide beauty and utility for shaded Southern gardens. These ground-hugging perennials do not offer flower or fruit, but their myriad forms, leaf sizes, leaf colors, and unique textures provide a wealth of interest for difficult garden sites.
The amount of variation in ferns is surprising to most gardeners, as are the many cultivars and types suitable for planting in Mississippi's climate.
How to Grow Ferns
Ferns are surprisingly easy to establish and maintain. One of their few requirements is to be planted in a shaded area, particularly one that is protected from the hot afternoon sun. Most cultivated ferns prefer a loose well-drained organic soil, but there are native cultivars well suited to poor or even wet soil types. Ferns should be planted in the spring, after all danger of frost is passed. Loosen the top four inches of soil in the area that the ferns are to be planted, and mix in well-cured compost or peat moss into the soil. The loose soil will allow fern rhizomes (an underground horizontal stem that roots at the nodes) to quickly spread and colonize the planting area. Do not disturb any existing tree roots that may be uncovered, instead simply plant the ferns around the existing roots. Cover the area with a thick layer of leaves or mulch to retain moisture. It will be important to make sure that ferns are kept moist until they are fully rooted and established. The addition of a soaker hose hidden in the mulch provides an easy method for frequent watering. Once mulched and established, ferns require little watering, fertilizing, or further care. Only during extreme droughts will additional watering usually become necessary.
Planting Compositions with Ferns
Since most ferns have very fine textured leaves, they can be effectively combined with bold, coarse-textured shade plants. Cast iron plant, bear's breech, dwarf palmetto, gingers, split-leaf philodendron, umbrella plant, and aridisa are examples of broad leaf plants that provide striking accents to ferns. Different fern types can offer a lighter green or darker green leaf color, and some even have a tinge of silver or blue. Variegated plants such as variegated vinca, ajuga, variegated Algerian ivy, hostas, ligularia, and other perennials can provide color accents for a primarily green garden. Since some ferns spread aggressively by rhizomes, such as sword fern, it is suggested to choose accompanying plants accordingly.
Ferns Types for Mississippi
Although the variety of ferns suitable for growing in Mississippi is fairly extensive, the following abbreviated list features commonly available types.
|Scientific Name||Common Name|
Woodwardia (Lorinseria) areolata

The oldest castle on the hill probably dates back to the 11th century. Written sources mention it in 1144 as the seat of the feudal estate of the Carinthian Dukes of Spanheim. In the first half of the 13th century they conferred town privileges on the settlement on the Ljubljanica River. In approximately the same period a stone-built fortress was erected on the Castle Hill to better protect the town; together with the two extensions of the town walls, it closed the fortification ring of Mestni trg (Town Square). In 1335 the castle was transferred into the seat of Carniola to the Habsburgs, thereafter remaining their hereditary property for several centuries.
The present castle, historically the third one, was built by the Duke, later Emperor, Frederick III. It was erected in the 15th century after its predecessor had been completely destroyed. Except for the outer walls, the castle chapel, the corner towers and two entrance towers, the rest of the buildings originated in the 16th and 17th centuries.
As late as 1848 the appearance of the castle was enhanced by the dominant watchtower replacing the wooden one, which gave the present architectural ensemble its final form and the castle its characteristic silhouette, corrected in 1990s.
During its long and varied history the castle was mostly a military fortress, but also functioned as the seat of provincial rulers, with the city tower being used by pipers and fire guards. In spite of all this the role of the castle gradually dwindled, as did the strategic importance of the fortress and walls. It was rescued from total destruction by a governmental decree in 1814 to turn it into a penal institution. In 1905 the castle was bought by the City of Ljubljana and turned into multi-residential building for the citizens, but mainly for prisoners and the poor.
Since 1988 the Municipality of Ljubljana has been carrying out continuous archaeological research at Ljubljana Castle, which confirmed the continuous settlement of the hilltop.
In the 1930sidea was to build a new conical parliament to replace the castle, but he managed to realise only Šance (redesigned remains of the fortifications) and the avenue. The first renovation work was carried out in 1940s according to town planner. The recent renovation work was carried out in 1964–2004 by architects,, and, which gave the castle a new steeper roof, a higher watchtower, new access, and a regulated defensive corridor around the margin of the former fortified walls, linking the renovated castle structures together.
At the end of 2006 the Municipality of Ljubljana connected the Ljubljana Castle with the historic city centre by an urban means of transport – a funicular railway. The ride up the slope of the castle hill has been included in a regular guided walking tour of the city organised by the Ljubljana Tourist Board. The lower station of the funicular railway is located at Krek Square, next to the Ljubljana Puppet Theatre and the Dome, just across from the city's open-air marketplace.
Premises and permanent exhibitions
The castle offers a tourist viewing tower, a virtual museum, a chapel, and several cultural venues: Hribar's Hall, Palatium, Pentagonal Tower, Rocks Hall, Estate Hall, White and Blue Halls, Erasmus Tower, Archers' Tower and Pipers' Tower. Cultural events, such as Gustav Film's Comedy under the Stars, also take place in the castle courtyard. In addition to performing arts events, exhibition projects and film screenings (i.e. Kinodvor Cinema's Film under the Stars during the summertime), and some permanent exhibitions featuring the history of the city are displayed at Ljubljana Castle.

A new review of research released by the New Zealand Breast Thermography Association (www.nzbta.org.nz) Wednesday has revealed that thermography is a highly effective tool for predicting breast cancer risk. To date, the most important risk factor for developing breast cancer, aside from being female and getting older, is having a family history of the disease. While considered significant, a family history accounts for only 5 – 10% of breast cancers diagnosed, while 60 – 70% of women diagnosed have no recognised risk factors. What this means is that women are largely in the dark when it comes to understanding their personal risk of developing the disease.
“The results of the literature review show that a persistently abnormal thermogram is an extremely strong indicator of breast cancer risk” says medical researcher Corene Humphreys BHSc, ND. “A persistently abnormal thermogram is considered by a number of researchers to be ‘the single greatest indicator of breast cancer risk’, and ten times more important than a family history of the disease.” she continues.

Olympic.ca’s celebration of Canada’s sesquicentennial reaches the Roaring Twenties this week.
As we continue to reflect on key moments in Canadian sport since confederation, if you find yourself in need of a refresher, all our past installments can be found here.
The 1920s were a decade that represented a break from traditions, some of which were felt in the Olympic world. Women took a more prominent place in international sport while winter sports were given their own Olympic spotlight.
1920 – Canada’s Best Ever Olympic Boxing Medal Haul
Over the course of the 20th century, Canada has won 17 Olympic medals in boxing. The biggest haul came at the first Games at which Canadian boxers stepped on the podium, Antwerp 1920, where they won five medals in the eight events on the program.
The lone gold came from Albert Schneider in the welterweight division. He had thrown himself into training as a boxer after being barred from joining from Royal Canadian Army at the start of World War I because he was not yet a Canadian citizen. Despite still not having obtained citizenship, he was selected to represent Canada in Antwerp.
Silver medals were won by Cliff Graham in the bantamweight division and Art Prud’homme in the middleweight division. The latter was joined on the podium by Moe Herscovitch, who captured middleweight bronze. A bronze medal was also won by lightweight Chris Newton.

Every once in awhile, sports nutrition researchers change their minds. When they do, a common practice that athletes thought was based on solid science may be exposed as a myth. One recent example is the practice of consuming salt tablets during races to prevent muscle cramps. Scientists now know that exercise-associated muscle cramps are not caused by the loss of electrolyte minerals in sweat, as they had believed since the 1930s. Rather, they are caused by an abnormal nervous system response to extreme fatigue in individual working muscles.
When a common sports nutrition practice, such as taking salt tablets during races (which may be beneficial for reasons other than preventing muscle cramps), is revealed to be baseless, athletes can’t help but turn a skeptical eye toward other practices. What will we learn next—that eating within 30 minutes after completing a workout does not, in fact, accelerate muscle recovery and improve performance in the next day’s workout?
Let’s take a closer look at the science behind immediate post-workout nutrition intake. When we do, we quickly discover that the 30-minute threshold is somewhat arbitrary. There are no studies showing that eating a snack, say, 25 minutes after exercise results in faster recovery than consuming the same snack 35 minutes after exercise. However, there is plenty of evidence that eating immediately after a workout is better than waiting a long time.
In 2001, for example, researchers at Vanderbilt University Medical Center in Nashville, Tenn., fed volunteers a snack containing 10 grams of protein, 8 grams of carbohydrates and 3 grams of fat either immediately or three hours after completing 60 minutes of moderate-intensity exercise. Two of the most important recovery processes are:
- Replenishment of muscle glycogen fuel stores, which requires carbohydrates
- Muscle repair, which requires protein
The researchers found that postexercise muscle glycogen synthesis proceeded 44% faster, and protein synthesis in the exercised muscles 300% faster, when the volunteers ate immediately after their workouts.
Other studies have proven that accelerated muscle refueling and repair translates into better performance in the next workout. In one such study, exercise physiologists at the University of Texas asked 10 cyclists to complete a 90-minute ride followed four hours later by a 40K time trial on three separate occasions. On one occasion, the cyclists were given chocolate milk (containing carbohydrates and protein) to drink immediately after and again two hours after the first ride. On a second occasion, they were given a drink containing carbs but no protein. And on a third occasion, they were given a noncaloric placebo. On average, the cyclists completed the time trial more than six minutes faster after consuming carbs and protein than they did after consuming carbs alone, and more than seven minutes faster than they did after consuming flavored water.
Of course, it’s not often that you’ll want to complete a 90-minute workout and an all-out time trial on the same day, but these results show that faster muscle recovery resulting from immediate post-workout nutrition intake has the practical benefit of enabling the muscles to perform better the next time they are challenged. This study also confirms that the ideal post-workout snack, meal or supplement contains both carbohydrates and protein.
The benefits of immediate post-workout nutrition intake don’t end here, though. It is well-known that the physiological processes through which the muscles recover from exercise overlap with the processes through which the body adapts to training. Based on this knowledge, the same research team that performed the study just described conducted a follow-up study in which they measured the effects of repeatedly consuming one of the same three beverages after daily workouts on changes in aerobic capacity (VO2 max) and body composition. After one month of training, the subjects receiving the carbohydrate-protein beverage were found to have made more than double the gains in aerobic capacity than the other two groups, while also gaining more muscle and losing more fat.
That’s right: Habitually consuming appropriate nutrition after workouts will not only allow you to recover faster and perform better in your next workout, but it will also make you fitter and leaner than if you did the same training without this habit.
Most of the research in this area has involved packaged products such as recovery beverages and chocolate milk. It is not necessary to use such products, however. Literally anything that contains carbs and protein will do the trick. Indeed, a news-making 2015 study done at the University of Montana found that fast food facilitated muscle recovery about as well as a commercial recovery beverage. A better choice for health reasons, though, would be a high-quality natural food with carbs and protein such as yogurt and fruit, a turkey sandwich or an omelet with cheese and vegetab

X3J13 voted in June 1988 (FUNCTION-TYPE) to allow the function to be only of type symbol or function; a lambda-expression is no longer acceptable as a functional argument. One must use the function special form or the abbreviation #' before a lambda-expression that appears as an explicit argument form.
The arguments for the function consist of the last argument to apply appended to the end of a list of all the other arguments to apply but the function itself; it is as if all the arguments to apply except the function were given to list* to create the argument list. For example:
(setq f '+) (apply f '(1 2)) => 3 (setq f #'-) (apply f '(1 2)) => -1 (apply #'max 3 5 '(2 7 3)) => 7 (apply 'cons '((+ 2 3) 4)) => ((+ 2 3). 4) not (5. 4) (apply #'+ '()) => 0
Note that if the function takes keyword arguments, the keywords as well as the corresponding values must appear in the argument list:
(apply #'(lambda (&key a b) (list a b)) '(:b 3)) => (nil 3)
This can be very useful in conjunction with the &allow-other-keys feature:
(defun foo (size &rest keys &key double &allow-other-keys) (let ((v (apply #'make-array size :allow-other-keys t keys))) (if double (concatenate (type-of v) v v) v))) (foo 4 :initial-contents '(a b c d) :double t) => #(a b c d a b c d)
funcall fn &rest arguments
(funcall fn a1 a2... an) applies the function fn to the arguments a1, a2,..., an. The fn may not be a special form or a macro; this would not be meaningful.
X3J13 voted in June 1988 (FUNCTION-TYPE) to allow the fn to be only of type symbol or function; a lambda-expression is no longer acceptable as a functional argument. One must use the function special form or the abbreviation #' before a lambda-expression that appears as an explicit argument form.
(cons 1 2) => (1. 2) (setq cons (symbol-function '+)) (funcall cons 1 2) => 3
The difference between funcall and an ordinary function call is that the function is obtained by ordinary Lisp evaluation rather than by the special interpretation of the function position that normally occurs.
The value of call-arguments-limit is a positive integer that is the upper exclusive bound on the number of arguments that may be passed to a function. This bound depends on the implementation but will not be smaller than 50. (Implementors are encouraged to make this limit as large as practicable without sacrificing performance.) The value of call-arguments-limit must be at least as great as that of lambda-parameters-limit. See also multiple-values-limit.

Most people understand that exposure to very loud noises can hurt your ears and overtime it can negatively impact your hearing ability. But as a recent New York Times article explains, it’s also the chronic exposure to all sounds, not even particularly loud ones, that can wreak havoc on hearing and your mental state.
Noise not only makes hearing, concentrating, and working more difficult, it disturbs sleep which in turn results in stress, fatigue, and changes in body’s chemical balances. Noise pollution also interferes with cognitive functions, including attention, concentration, memory, and reading ability. Since we spend a huge amount of time at home, starting to reduce sound within your living space will help stop noise pollution and the stresses and irritability that comes along with it. While urban noise may seem inevitable and unavoidable, even the most dense and active places can take steps to limit noise.
- Creative Approach.
Adding a cork board, or heavy wool yardage on the underside of tables can help counteract bad acoustics. Using fabric on walls and ceilings in creative ways can also absorb and scatter sounds in rooms. Decorate your living space while keeping in mind how sound waves reflect off flat surfaces and perpendicular walls, possibly staggering a bookshelf or adding curves and corners to a room to mitigate internal noise echo.
- Implement a “No Shoes” Policy.
Eliminate the clatter of heels and clogs and everyone will thank you. It is not only reducing the noises within a home, but also provides huge health benefits. A study done by microbiologist Charles Gerba, PhD, revealed that the outside of a shoe contains an average of 421,000 units of bacteria, including those responsible for bloodstream infections, pneumonia, and respiratory tract infections.
- Surround Yourself With Calming Sounds.
The sounds of nature are ideal. But what should you do if you live in the city, and the only sounds that you hear after opening the window are traffic horns and barking dogs? You can use the progress of technology to change your apartment environment. You can purchase specialized white noise machines to mask the outside sounds, and there are even phone apps which allow you to set the ambience in your home with soothing background noises.
- Turn Off The Devices.
Don’t forget to turn off the devices you are not using. Before sitting down to watch a movie, turn off the computer, cable box or gaming console (with their noisy fans) so

More About Einstein by Walter IsaacsonOverviewBy the author of the acclaimed bestseller Benjamin Franklin, this is the first full biography of Albert Einstein since all of his papers have become available.
How did his mind work? What made him a genius? Isaacson's biography shows how his scientific imagination sprang from the rebellious nature of his personality. His fascinating story is a testament to the connection between creativity and freedom.
Based on newly released personal letters of Einstein, this book explores how an imaginative, impertinent patent clerk -- a struggling father in a difficult marriage who couldn't get a teaching job or a doctorate -- became the mind reader of the creator of the cosmos, the locksmith of the mysteries of the atom and the universe. His success came from questioning conventional wisdom and marveling at mysteries that struck others as mundane. This led him to embrace a morality and politics based on respect for free minds, free spirits, and free individuals.
These traits are just as vital for this new century of globalization, in which our success will depend on our creativity, as they were for the beginning of the last century, when Einstein helped usher in the modern age.
Einstein, the joyous nonconformist, is Isaacson's latest subject
It is redundant to say that Albert Einstein is the world's most famous scientist. Merely stating his name is sufficient to make the point. T-shirts, posters, action figures and innumerab

By Dr. Joseph Mercola
with Rachael Droege
Essential oils carry the physical properties of flowers and plantsin a highly concentrated form. They are, in short, the essence ofthe plant and can provide therapeutic benefits in very small amounts.The particles in essential oils, which come from various parts ofthe plant such as the flowers, twigs, leaves or bark, can be inhaledand absorbed through the skin and their use can be traced back forthousands of years. Essential oils were even used in ancient Egyptiantimes, and were made by soaking plants in oil and then filteringthe oil through a linen bag.
Most essential oils have antibacterial qualities and have varyingphysical and emotional effects depending on the oil, such as stimulation,relaxation, pain relief and healing. The most common ways to useessential oils include:
- Massaging them (blended with a carrier oil) into the skin
- Adding them to bathwater
- Using them in a compress
- Burning them in a diffuser
In The Maker's Diet, Dr. Jordan Rubin recommends 14 essentialoils that have unique healing properties. He suggests putting fiveto 10 drops (total) of these "top healing oils" into awarm bath for a real "healing treat." Below you will findfive beneficial essential oils along with their uses. I encourageyou to check out The Maker'sDiet to learn more about some of the more exotic, but highlyeffective, essential oils available.
I'd also like to point out that essential oils are not the samething as fragrance oils. Essential oils come from plants while fragranceoils are artificially created and often contain synthetic chemicals.While they may smell good and are typically less expensive, theywill not give you the therapeutic benefits of organic essentialoils--and you don't want to be inhaling any synthetic chemicals!So, please be sure that the essential oil you use is of the highestquality and 100 percent pure.
Caution: Essential oils can produce verystrong and significant changes in tiny amounts. They must be usedwith caution, especially during pregnancy. It is important to consultsomeone knowledgeable in aromatherapy before experimenting withthese oils.
* Although sandalwood is a beneficial oil, the treesmust be felled to collect the product and there has been much over-harvesting.Indian sandalwood is controlled by the Indian government, whichallows a limited amount of the essential oil to be traded on theworld market. However, due to its high value sandalwood may be producedillegally without replanting programs in place. There is concernthat this oil should be on the endangered list and many essentialoil producers are contemplating not selling it, so you may wantto seek an alternative oil, such as Western Australian sandalwood.

Sitting on the fence? Economics and ideas?
There have been attempts to try and understand patriarchy and capitalism as intricately intertwined systems of both material and symbolic production. Dual-systems theorists (see Chapter 4) like Sylvia Walby, for example, concede that material and symbolic factors may have varying and unequal influence in the formation and shifting of inequalities. In her
book Theorizing Patriarchy (Walby, 1990), she sets out a framework for understanding the patriarchal system and how it connects with capitalism. She argues that patriarchy is made up of six structures: paid work, household production, culture, sexuality, violence, and the state. Notice that she includes here not only economic arrangements (which she argues are currently capitalist) of paid and domestic work, but aspects materialists have struggled adequately to address such as culture and sexuality.
Later Walby (1996) develops her dual-systems approach and further investigates the extent of changes in gender relations in the last half of the twentieth century. In Gender Transformations she continues her earlier argument that western nations have moved from a system of private (domestic) patriarchy to public patriarchy. What she means is that prior to the mid-twentieth century women’s lives were more likely to be controlled and constrained by the men within their immediate family. Women were dependent on fathers and then husbands. As women entered the workforce in greater numbers from World War II onwards, this gradually changed. Now, Walby argues, patriarchal domination of women operates chiefly within the public world of work and politics. Many women have financial independence, and may not need to rely on individual men to survive, but collective decisions affecting their lives are usually made by men. Politicians, who are nearly all men, make laws affecting them (like how much benefit single mothers can have); bosses who are mostly male adhere to policies that (either intentionally or unintentionally) discriminate against women. Both public and private patriarchy operate within contemporary society, but the dominant form is now public. The old domestic form excluded women from the public sphere, while the new ‘public’ form segregates them into particular jobs and into the lower levels of the hierarchy. Walby goes on to stress that young women’s lives are more likely to be affected by public patriarchy. This is because younger women are more likely to have an education and to get jobs that allow a degree of independence from individual men. This may change as they get older and start families, though this depends on whether and how they continue to work. Many older women’s lives still need to be understood in terms of the domestic system of patriarchy, which still operates for those who have not had the education, skills and work experience of the younger generation of women and who are still likely to be largely dependent upon husbands. Both types of patriarchy impact differently on different women depending on their class, age, position in the life course (for example before or after having children), and ethnicity.
Walby’s approach is helpful in portraying the complexities and shifts in contemporary gender relations. However, her account of the relationship between the symbolic and the material production of gender
inequalities is rather sketchy. Where cultural processes are considered they tend to be linked back to economics. Though the cultural is not independent of the economic, Walby needs to think more about why it is that discourses of equality coexist with manifest inequalities. In other words, many women (and men) appear to think that equality between the sexes has been achieved. Though she presents a great deal of evidence to show that gender inequalities continue to exist, she says little about why people might think all is equal now. Demonstrable changes in gender relations therefore need to be carefully considered within the context of how people make sense of those changes.
As noted earlier, young women who are social science and humanities students may see themselves as having the same opportunities as men. This may be because so far their experiences of the public world have been largely within the areas of the education sector where equality is well advanced. They expect to have autonomy, especially financially, and not to be controlled by fathers or husbands. Walby argues that for younger women gender inequalities are publicly located. But perhaps these inequalities are just more visible within the public sphere. For instance, in the area of work Walby emphasizes economic inequalities. She fails to consider, for example, the problems of women having to take on masculine values to succeed at work. Such cultural values may be a major factor in understanding the interweaving of capitalism and patriarchy. Perhaps the reason ‘public’ gender inequalities are more noticeable is because work, politics and other ‘public’ activities are what men take seriously and consider important. Therefore inequalities within the private sphere are rendered invisible and/or trivialized. So, according to Walby, women’s social position has been improved (largely through women’s political participation) but male resistance continues and the way in which gender inequalities operate has changed and shifted, becoming perhaps less obvious and less direct.
Walby’s is just one account of how and why women’s and men’s lives and their relations to each other have changed, but it provides a big picture of women’s place

THE RESULTING CARNAGE OF THE ILLEGAL TRADE OF ANIMAL PARTS. This
mountain gorilla killed by poachers was one of many killed for tourist
trade of gorilla heads and hands.
By Ciara Rickard
Though its necessity has long since waned in most areas of the Western
world, hunting has remained a favoured sport practiced by many in modern
society. While there are laws monitoring this activity, there is still a
great deal of illegal hunting which goes on in Canada and around the world
in order to feed a market which craves various animal parts.
Some statistics show poaching has had a devastating impact on animal
populations. While some uses of it are medicinal, some are served as
delicacies and some of the uses are seen as entirely frivolous.
"Any poaching is not legitimate," says Anthony Marr, biodiversity campaign
director for the Western Canada Wilderness Committee. "It's big business,
just second to the drug trade and often connected to the same people.
Wherever there is a demand, there will be a supply."
Marr has spent a great deal of time and effort trying to educate people
and the government about the ill consequences of poaching and the
importance of maintaining animal populations. At greatest risk in Canada,
he says, are the black and grizzly bears, which are hunted primarily for
their gall bladders and their paws.
"We estimate that about 22,000 to 29,000 black bears are killed per year,"
Marr says. "That's out of a population of about 400,000, so that's about
12 per cent. That is not sustainable. They can't reproduce quickly enough
to maintain the population."
Liz White, a director for the Animal Alliance, points out how these
numbers may not be accurate. Because poaching is an illegal activity, no
one knows about it and therefore no one can know the actual number of
bears dying each year.
"The paws are a delicacy in Asian cultures," Marr says. The gall bladders,
also for the Asian market, contain cholic acid derivatives, which are
considered very valuable and effective medicine by Asians. Though there is
a synthetic process to create the same chemicals, most Asians will still
opt for the medicine from the bear.
"Tradition has a powerful sway over people's actions," Marr says.
"Traditional medicine has a mixture of medicine and mystique."
The market for most animal parts is centred in Asia where tradition
dictates what is the best cure for a variety of ailments. The reason there
is so much poaching in Canada is because Asian bear populations have
already been depleted from hunting, so they've had to go elsewhere, Marr
says. He is also quick to point out that not all Asians use medicine or
food containing bear parts.
"It's a different cultural attitude in Canada than in Asia toward the use
of animals," White says. "Asians are horrified by the fact that we hunt
bears to wear their skins – they'd never do that. But they see nothing
wrong with killing the animal, eating it and using its parts for various
Bears aren't the only animals at risk. Seals in Canada are hunted for
their penises as they are considered to have aphrodisiac powers, White
says. Tigers are also hunted for this purpose.
"There's a growing push for aphrodisiacs from tusks, bones and seal
penis," White says. "Some people have joked that Viagra will be the
salvation of the animals."
However, not everyone considers this aspect of the illegal trade of animal
parts to be particularly serious.
"The people who use it [aphrodisiacs made from animal parts] are mostly
fringe groups, so animal groups don't consider i

Fear the Media Meltdown, Not the Nuclear One (UPDATED)
The March 11 earthquake off the coast of Japan has been an unprecedented disaster. Now estimated to have been a magnitude 9 earthquake -- one of the top five earthquakes measured since reporting started in 1900 -- it was the result of a "megathrust" in which an area of sea floor bigger than the state of Connecticut broke free and moved under the force of colliding tectonic plates. It was so strong that it literally moved the entire island of Honshu eight feet to the east. The earthquake was then followed by a tsunami comparable to the Boxing Day tsunami of 2004 -- but since the epicenter of the quake was only a few miles off the coast of Japan, the tsunami struck the heavily populated coast of Honshu with almost no warning, basically washing many coastal villages off the face of the earth.
The earthquake and tsunami seriously damaged reactors at the Fukushima Daiichi ("number one") and Daini ("number two") in Okuma, in Fukushima Prefecture, and also damaged the Onagawa plant in Miyagi Prefecture. In total, of the 55 nuclear power generation plants in Japan, 11 have been forced to shut down, cutting power generation capacity in Japan dramatically and forcing the country to adopt a series of rolling blackouts. It would seem impossible to overstate the severity of the crisis.
The media, however, has risen to the challenge, with a combination of poor information, ignorance, and alarmism, along with antinuclear activists passing themselves off as unbiased experts.
Let's try to make some sense of it all.
Basics of How Reactors Work
The Fukushima plants have several reactors built on the same basic design, either by GE or by Japanese companies licensed by GE. These are all "boiling water" reactors, which means just what it sounds like: the heat of the nuclear reaction boils water; the steam generated is used to drive turbines and thereby generate power. The water in direct contact with the reactor core known as "coolant" is nothing particularly special, just demineralized; water itself isn't very susceptible to becoming radioactive, but minerals and contaminants in the water can be. If the water is purified, there's less radioactive waste to deal with.
The cooling water is pumped past the reactor core in normal operation to get the energy with which power is generated, and of course to cool the core. If there's an accident, the reactor is shut down by inserting the "control rods," made of some material that absorbs neutrons and so slows the nuclear fission from which the reactor gets its power. Even a shut down reactor continues to need cooling, however; there's an immense amount of residual heat still left in the reactor core. This means continuing to run the pumps, and of course with the reactor shut down they can't be run from the reactor's power, so there are diesel generators as a backup, and batteries as a further backup to the generator.
If all the cooling fails for some reason, the accumulated heat can't escape; the water boils away, and once it's gone, the materials that make up the reactor core break down. This is a Bad Thing, because the controls on the reactor fuel also break down; it starts to heat up again. This is what's called a meltdown. When this happened at Chernobyl, the reactor core quickly became hot enough to vaporize the reactor's fuel and a good part of the other material around it, leading to an explosion that destroyed the building that housed the reactor.
To prevent that from happening in commercial reactors in the capitalist bloc, the reactor is inside three concentric safety vessels: first, the "boiler" itself; second, a massive steel bottle; and third, an even larger and more massive reinforced steel, concrete, and graphite outer containment vessel. In case of a meltdown, the whole reactor should be contained within the steel secondary containment vessel, but if it's not, the molten reactor core drops to the graphite floor of the third vessel, where it spreads out across the floor. This causes the reactor to stop, and it can cool naturally. Eventually the pieces can be cleaned up.
This whole structure is then inside a big conventional steel building that is the outside wall of the reactor complex.
What happened at Fukushima Daiichi
The original earthquake hit. Three of the six reactors were in operation, the other three were shut down for scheduled maintenance. The reactors were designed to sustain an earthquake of magnitude 8.2; at magnitude 9, the Honshu quake was 16 times more powerful. This caused the plant to automatically shut down; this was apparently successful, but...
About an hour later, the tsunami hit. The tsunami did two significant things: it destroyed the backup generators that kept the pumps running, and it apparently so contaminated the reserve coolant that it was not only no longer pure, but was so mucked up with the scourings of the tsunami that it couldn't be safely pumped. At this point, the reactor was in some trouble.
As the reactor heated up, water began to react with the zirconium fuel-rod containers, liberating hydrogen, which started to build up in the boiler. The operators began to vent gases from the reactor to reduce the pressure, liberating the hydrogen into the outer façade building. These gases are mildly radioactive, mainly with nitrogen-16 and several isotopes of xenon, all products of the fission reaction that powers t

LOCATION DETAILS: In the area of Louisiana known as Honey Island Swamp. I was told this by my stepfather and stepbrother. They lived near this area before we met. The sighting was beside a river that runs through the swamp, I do not recall the name of it, maybe you know.
OBSERVED: My stepbrother had a friend who he considered a brother, and was considered a son to my stepfather. He and his dad hunted frequently in Honey Island Swamp. I'm told their were very few who knew the area as they did.
They were hunting one day, it was cloudy and misting. They were walking up to the river when they heard a splash. They turned to see a dark hairy creature, very muscular, standing with i

I’d like to think that adult logic takes over at some point, as we develop critical thinking based on sound argument—but that is only partially true. At any age, we are shaped by the habits of our kithmates, or circle of peers. Social learning, as behavior analysts have discovered, has more influence on adults than we would like to believe, manifesting itself in sometimes subconscious ways.
So consider this the next time you find yourself spending time with people who are unhappy, pessimistic and, simply put, unsuccessful. You will likely become the same way.
But there’s good news—just as you can absorb the bad habits and attitude of the wrong crowd, you can absorb the good traits of the right crowd, who are happy, self-confident and optimistic.
While teaching at the McColl School of Business at Queens University in Charlotte, N.C., I have noticed that the most successful MBA students form cohesive networks of support for one another as they participate in the two-year program. These students keep current on one another’s careers and personal challenges. They show their colleagues ways to take risks to be happy. They refer to this peer-group experience as transformational and have gone on to make courageous, life-changing decisions.
The strength of social influence demands a review of your network. Here are five ways to do so:
1. Take inventory. Identify people with negative energy—people around you who are most likely to express an overall bad attitude. Consider who drains you of energy, who is constantly complaining, and who doesn’t celebrate your success. Be especially vigilant for emotional states of anger and frustration.
Researchers have discovered an “emotional contagion” phenomenon in which your emotions will actually converge with those of your peers. Negative emotions exert a powerful effect in social situations, so take inventory carefully.
2. Put some space between you and these people. Pull back from spending time with people who are in constant pessimism or drama. Avoid low-energy people who don’t encourage you to be your best. There is no need to be abrupt or impolite, but make choices to avoid exposure to negativity.
3. Prioritize and be intentional. Increase proximity with people who have a successful, energetic spirit. Gravitate to those who encourage your success. Consciously work to cultivate a close, exceptional group of peers and teammates who will help you grow and adopt effective habits.
4. Ask for feedback. In and outside of work, elicit the advice of people you want to emulate. Collaborate with people who are engaged. Ask for their advice, guidance and mentorship. Those wishing to take quantum leaps have no need for people to tell them what they want to hear. Friends and family members who will shoot straight and communicate with candor are priceless.
5. Develop your own positivity as a leader. Successful leaders who express positivity in the workplace are known for having a touch of charisma. This doesn’t mean you pour pink paint on everything, which is off-putting. It means you insist on an environment in which people thrive. It means you develop and reinforce your habits with the help of peers who express positivity. In turn, your teammates will experience a positive emotional contagion and support a culture of productivity.
What could running with the right crowd mean to you? Imagine traveling through life with a group of smart, enthusiastic peers who are completely engaged in living a large, successful and happy life, never settling for less, and always showing you the way to stretch and go for it. What would happen? You would live a large, successful and happy life.
As usual, Mom was right.

An autoregressive model (AR) is also known in the filter design industry as an infinite impulse response filter (IIR) or an all pole filter, and is sometimes known as a maximum entropy model in physics applications. There is "memory" or feedback and therefore the system can generate internal dynamics.The definition that will be used here is as follows
where ai are the auto-regression coefficients, xt is the series under investigation, and N is the order (length) of the filter which is generally very much less than the length of the series. The noise term or residue, epsilon in the above, is almost always assumed to be Gaussian white noise.
Verbally, the current term of the series can be estimated by a linear weighted sum of previous terms in the series. The weights are the auto-regression coefficients.
The problem in AR analysis is to derive the "best" values for ai given a series xt. The majority of methods assume the series xt is linear and stationary. By convention the the series xt is assumed to be zero mean, if not this is simply another term a0 in front of the summation in the equation above.
A number of techniques exist for computing AR coefficients. The main two categories are least squares and Burg method. Within each of these there are a few variants, the most common least squares method is based upon the Yule-Walker equations. MatLab has a wide range of supported techniques, note that when comparing algorithms from different sources there are two common variations, first is whether or not the mean is removed from the series, the second is the sign of the coefficients returned (this depends on the definition and is fixed by simply inverting the sign of all the coefficients).
The most common method for deriving the coefficients involves multiplying the definition above by xt-d, taking the expectation values and normalising (see Box and Jenkins, 1976) gives a set of linear equations called the Yule-Walker equations that can be written in matrix form as
where rd is the autocorrelation coefficient at delay d. Note: the diagonal is r0 = 1.
The following example is presented with some degree of detail in order to allow replication and comparison of the results with other packages. The data is 1000 samples from a sum of 4 sinusoids and is provided here. The data looks like this
While not particularly useful, an order 1 AR analysis gives a coefficient of 0.941872, this is not totally surprising as it is saying that by only looking at one term in the series the next term in the series is probably almost the same, ie: xt+1 = 0.941872 * xt
The following table gives the coefficients for a number of model orders for the example above.
| Coefficients Order | 1 2 3 4 5 6 7 8 ----- | -------- --------- -------- --------- --------- --------- -------- --------- 1 | 0.941872 2 | 1.826156 -0.938849 3 | 2.753231 -2.740306 0.985501 4 | 3.736794 -5.474295 3.731127 -0.996783 8 | 4.259079 -6.232740 2.107323 2.969714 -1.421269 -2.591832 2.614633 -0.704923
As the order increases the estimates generally improve (this may not necessarily be so for noisy data when employing large AR orders!). It is often useful to plot the RMS error between the series estimated by the AR coefficients and the actual series. An example for the above case is shown below
As is typical in AR analysis, the RMS error drops away very fast and then evens out.
The RMS error stays constant as the AR order is increased.
Most AR routines fail in this case even though the solution is straightforward (a1 = 1, else ai = 0). A singular matrix results for the least squares formulation.Test 1
Perhaps the best way to test code for computing AR coefficients is to generate artificial series with known coefficients and then check that the AR calculation gives the same results. For example one can genera

From the Eneolithic to the Late Bronze Age vast areas of Eurasia were inhabited by a series of highly mobile and innovative groups that mostly relied on pastoralism for subsistence and, judging by their warlike grave goods, didn't mind a bit of biffo.
In Europe, where they first appeared, their archeological remains are generally classified as part of the Corded Ware Culture (or its Battle-Axe and Single Grave offshoots), and in Asia, where they expanded rapidly from the Trans-Urals to the Pamirs and south Siberia, as part of the Sintashta, Petrovka and Andronovo cultures.
It's likely that these groups had a profound impact on the Bronze Age world, including on Mycenaean Greece and Hittite Anatolia. The Sintashta Culture, for instance, is credited with the development of the spoked-wheel chariot, which became widely used in warfare all the way from Egypt to China.
Unfortunately, a lot of nonsense has been written on this topic in the past. In my view, one of the most sensible and up do date sources currently online is the thesis The Origin and Spread of the War Chariot by Elias Manuel Morgado Pinheiro.
Indeed, the obvious awesomeness of these ancient people has stirred much controversy about their origins and legacy. The academic consensus is that they were closely related, and that at least some of their ancestors were early Indo-Europeans from Eneolithic Eastern Europe. But a few archeologists have argued that the Corded Ware Culture was native to Central Europe, and others that the Sintashta population arrived in the Trans-Urals from Iran or even Syria.
Moreover, linguists generally consider the Sintashta/Andronovo people as the most likely candidates for the Proto-Indo-Iranians, and thus the precursors of the Indo-Aryans. But this is contested by many Indologists, who prefer to see the deepest roots of the Indo-Iranians closer to India and often oppose the idea of an Aryan conquest of South Asia during the Bronze Age.
In the near future, probably within the next couple of years, ancient genomics will leave very little room for debate in these matters and the arguments will cease, at least in mainstream academia.
But we already have a reasonable collection of ancient DNA from the relevant archeological cultures. Does it back the general consensus? Let's take a look, starting with the Y-chromosome data sorted by culture. The bracketed numbers are the sample sources, which are listed at the bottom of the post.
Corded Ware, Germany, Individuals 2,3,4, R1aFascinating stuff. Keep in mind also that at higher resolution, most, if not all, of these R1a lineages are actually R1a1a1, which is estimated to be only around 5,000-6,000 years old based on full Y-Chromosome sequences. In other words, these groups were certainly closely related, and in large part the descendants of a patriarch who lived no earlier than the Middle or even Late Neolithic.
Corded Ware, Germany, I0104, R1a
Corded Ware, Germany, RISE434, R1a
Corded Ware, Germany, RISE436, R1a
Corded Ware, Poland, RISE1, R1b?

Sintashta, Trans-Urals, Russia, RISE392, R1a

Andronovo, South Siberia, Russia, S10, R1a
Andronovo, South Siberia, Russia, S16, R1a
Andronovo, Altai region, Russia, RISE512, R1a
Now, based on that list it might seem as if both R1a and Corded Ware were indeed native to North-Central Europe. But this is not so.
R1a appears to be an Eastern Hunter-Gatherer (EHG) marker that in all likelihood failed to penetrate west of present-day Ukraine until the Late Neolithic, because it's missing in all the relevant samples before this period. So it probably first arrived in Central Europe with the Corded Ware people. We know that the Corded Ware people were foreign to Central Europe because their genome-wide genetic structure is starkly different from that of the Middle Neolithic farmers who lived there before them.
This is easy to demonstrate. The Principal Component Analyses (PCA) below show where two ancient samples cluster alongside a variety of present-day West Eurasians from the Human Origins dataset. Note that Esperstedt_MN, a Middle Neolithic sample from a Baalberge Group burial in east-central Germany, looks more at home in Sardinia than Central Europe. On the other hand, the Corded Ware sample, also from east-central Germany, is sitting at the other end of the plot, among groups from the Volga-Ural region.
I'll throw in a few more PCA featuring Corded Ware, Battle-Axe, Sintashta and Andronovo genomes that offered enough data to be placed on the plots with a high degree of accuracy. Note that the only clear outlier is RISE512, an Andronovo sample with an inflated level of East Eurasian admixture. If you're having trouble finding the ancient samples, download the PDF files and use the PDF search field.
However, the meat and potatoes of ancient genomics are formal statistics. So in part 2 of this series I'll explore the genetic ancestry and legacy of the so called badasses of th

PRESS RELEASE, SEPT
19, 2005 BY THE NATIONAL INSTITUTE OF MENTAL HEALTH
NIMH Study To Guide Treatment Choices
A large study funded by NIH's National
Institute of Mental Health (NIMH) provides, for the first time, detailed information comparing the effectiveness and side
effects of five medications — both new and older medications — that are currently used to treat people with schizophrenia.
Overall, the medications were comparably effective but were associated with high rates of discontinuation due to intolerable
side effects or failure to adequately control symptoms. One new medication, olanzapine, was slightly better than the other
drugs but also was associated with significant weight-gain and metabolic changes. Surprisingly, the older, less expensive
medication used in the study generally performed as well as the newer medications. The study, which included more than 1,400
people, supplies important new information that will help doctors and patients choose the most appropriate medication according
to the patients' individual needs. The study results are published in the September 22 issue of the New England Journal
of Medicine. "The study has vital public health implications because it
provides doctors and patients with much-needed information comparing medication treatment options," said NIMH Director Thomas
R. Insel, M.D. "It is the largest, longest, and most comprehensive independent trial ever done to examine existing therapies
for this disease."
Schizophrenia, which affects 3.2 million
Americans, is a chronic, recurrent mental illness, characterized by hallucinations, delusions, and disordered thinking. The
medications used to treat the disorder are called antipsychotics. Previous studies have demonstrated that taking antipsychotic
medication is far more effective than taking no medicine, and that taking it consistently is essential to the long-term treatment
of this severe, disabling disorder. Although the medications alone are not sufficient to cure the disease, they are necessary
to manage it.
In the $42.6 million CATIE (Clinical Antipsychotic
Trials of Intervention Effectiveness) trial [$30,400/patient], researchers directly compared an older medication (perphenazine),
available since the 1950s, to four newer medications (olanzapine, quetiapine, risperidone, and ziprasidone), introduced in
the 1990s. The purpose of the study was to learn whether there are differences among the newer medications and whether the
newer medications hold significant advantages over the older medications; these newer medications known as atypical antipsychotics,
cost roughly 10 times as much as the older medications.
The size and scope of the trial, with
more than 1,400 participants at 57 sites around the country, its 18-month duration, and its inclusion of a wide range
of patients in a variety of treatment settings ensure that the findings are reliable and relevant to the 3.2 million Americans
suffering from schizophrenia.
At the beginning of the study, patients
were randomly assigned to receive one of the five medications. Almost three quarters of patients switched from their first
medication to a different medication. The patients started on olanzapine were less likely to be hospitalized for a psychotic
relapse and tended to stay on the medication longer than patients taking other medications. However, patients
on olanzapine also experienced substantially more weight gain and metabolic changes associated with an increased risk of diabetes
than those study participants taking the other drugs.
Contrary to expectations, movement side
effects (rigidity, stiff movements, tremor, and muscle restlessness) primarily associated with the older medications, were
not seen more frequently with perphenazine (the drug used to represent the class of older medications) than with the newer
drugs. The older medication was as well tolerated as the newer drugs and was equally effective as three of the newer medications.
The advantages of olanzapine — in symptom reduction and duration of treatment — over the older medication were
modest and must be weighed against the increased side effects of olanzapine.
Thus, taken as a whole, the newer medications
have no substantial advantage over the older medication used in this study. An important issue still to be considered is individual
differences in patient response to these drugs.

Probir Gupta’s canvases are enormous in their scale and narrative. A Kolkata art student during the Maoist uprising in India in the early 1970’s, Gupta demonstrated against routine acts of violence and terrorism. Gupta’s paintings appear as grand history paintings, containing intricate details and pulsating backgrounds. In Rats and Generals in a Zoological Park a sombre looking full-length portrait of Mahatma Gandhi stands robust in front of a coloured version of the Bayeux tapestry. Throughout the work, contoured figures and morose forms riddle the canvas. With his works, Gupta reorganises history into something messy, troubling and rueful in which nothing appears to take precedence.
Free Passage has been likened to Pablo Picasso’s 1937 painting Guernica. Gupta’s somber figures are depicted in black and white, with the words free passage painted across the canvas in Urdu. The inverted head of the statue of Liberty, camouflaged in army fatigue, emerges from what appears to be a pelvic region to the right of the canvas, as if in birth. The black and white figures possess a theatrical quality; they are shown witnessing the birth of an era of intolerance and violence. The forms appear on the brink of dissolving, as colour disappears from the foreground and becomes rooted into the distance.
Gupta’s portrait of the Bene Israel Family is a thoroughly engaging examination of the past. The Bene Israel were a group of Jewish emigrants, who settled in Cochin, in the southern part of the Indian sub continent, at the turn of the century. Research indicates

Coral Reefs (OCB-5930, OCE4930)
"Slow Life" is an amazing time lapse clip produced by Daniel Stoupin (http://www.microworldsphotography.com) revealing the motion of corals and sponges. In this video you also see how Fungia corals can excavate themselves even if they are buried deep in sand. Such ability is important for a coral that lives not attached to a substrate and can be carried away with currents and swells.
Coral reefs are among the most diverse and most fascinating ecosystems on earth. They are extremely productive ecosystems and play an important role in the global carbon cycle. They have been existing for more than two billion years and now are rapidly disappearing.
In this course the students learn about the processes that build, structure and destroy coral reefs. The lectures will address the interaction of the major biological, geochemical and hydrodynamical mechanisms that govern the functioning of the reef ecosystem. Topics include the biology of reef organisms and the processes that threaten reef ecosystems worldwide.

Stormwater runoff is often looked at as a unique issue associated with flooding. However, it is part of a larger process—the hydrologic cycle—that cleans and distributes water around the region. The hydrologic cycle has a significant impact on the natural environment, as well as people’s lives and the economy. Protecting and restoring site hydrology in development minimizes the impact to both public water supply and ecosystems. Managing stormwater on a watershed basis can reduce flooding. Employing stormwater Best Management Practices protects water quality in water resources that serve as water supply and support recreation.
Land that has not been disturbed by development produces only a small amount of runoff. The soil and vegetation slow and absorb rainfall and slowly release it to groundwater, surface waters, and the atmosphere. When development occurs, loss of vegetation, addition of impervious surfaces, and soil compaction disrupt this pre-development hydrology and greatly increase surface runoff. Maintaining the existing natural drainage and water cycle on a site during and after the development process to the greatest extent possible will minimize this disturbance. Stormwater Best Management Practices (BMPs) developed over the past decade can be used to preserve and restore site hydrology during development. Want more information on stormwater BMPs?
