Warren E. Weber - Retired Economist Published February 16, 2012 This paper examines two different clearing arrangements for bank liabilities. One was a profit-maximizing private entity, the Suffolk Banking System. It cleared notes for New England banks between 1827 and 1858. The other was a nonprofit collective, the clearinghouses organized in many cities beginning in 1853. The paper examines how well these arrangements prevented bank failures and acted as lenders of last resort. It finds the Suffolk system had fewer failures but acted less like a lender of last resort. It argues that these differences can be explained by the different incentives facing the Suffolk Bank and the members of clearinghouses. Download Paper (PDF)

Human Rights Day is celebrated annually across the world on 10 December. The date was chosen to honor the United Nations - General Assembly’s adoption and proclamation, on 10 December 1948, of the Universal Declaration of Human Rights (UDHR), the first global enunciation of human rights and one of the first major achievements of the new United Nations. “Today, poverty prevails as the gravest human rights challenge in the world. Combating poverty, deprivation and exclusion is not a matter of charity, and it does not depend on how rich a country is. By tackling poverty as a matter of human rights obligation, the world will have a better chance of abolishing this scourge in our lifetime… Poverty eradication is an achievable goal.” — UN High Commissioner for Human Rights Louise Arbour
The Distance and Borders on the Influence of Wage Differential in China Due to there is no record of migration in China, we estimate migration by Johnson¡¦s (2003) way. Estimates of migration among the provinces of China area were made
The Distance and Borders on the Influence of Wage Differential in China Due to there is no record of migration in China, we estimate migration by Johnson¡¦s (2003) way. Estimates of migration among the provinces of China area were made by comparison of the provincial population from the 1994 to the 2003 censuses. The estimates were made by comparing every year between 1995 and 2004 population of each province with what it would have been if population had increased solely due to national growth-the excess of births over deaths. Unfortunately, the estimate of the increase in provincial populations due to migration was much greater than the estimate of the loss of population by migration. Possible reasons for the difference in the estimates due primarily to the underestimation of immigrants. Because this difference amounts to less than 3% of the 1995-2004 population of China, the data is still useful to us. Because wage is a kind of price, we adopt the method by Engel and Rogers (1996), and use the law of one price to examine the wage differential in China area. We find that high migration gap, long distance and the presence of coast all lead to an increase in wage differential in China area. We also find that distance and border reduce differential among provinces. Note that the distance has a positive effect on wage differential, and the square of distance has a negative effect. This means the distance relationship were concave. Finally, we examine the tendency in the standard deviation of wage differential and migration gap among the provinces of China during the period 1994-2003. The standard deviation of wage differential widened, and the standard of migration gap did not display strong increasing or decreasing. Although the growth rate of wage differential was positive, it reduced in recent years. The average growth rate of migration gap was close to zero, there is not significant tendency.

What We've Learned About Dual Enrollment Katherine Hughes, a researcher at TC’s Community College Research Center reports on CCRC studies of high school students taking classes on college campuses This article originally appeared on betterhighschools.org, the blog of the National High Schools Center at the American Institutes for Research. Taking college courses while still in high school can lead to a range of positive college outcomes for students, according to two new studies released late last year by the National Center for Postsecondary Research (NCPR), led by the Community College Research Center (CCRC) at Teachers College. The two studies add to a growing body of research suggesting the value of dual enrollment, which has risen in popularity over the past decade as policymakers and educators have sought ways to smooth the transition from high school to college for many students. The CCRC studies found that the benefits of dual enrollment were not universal, however. One study found that dual enrollment students were 12 percent more likely to go to college and 7 percent more likely to earn a bachelor’s degree than non-dual enrollment students, but these strong effects were seen only for those students who took dual enrollment classes on college campuses. Students who took dual enrollment classes exclusively on their high school campus showed no statistically significant gains. To investigate just how beneficial the courses are, the second study compared students whose grade point average was just above and just below the cut-off to qualify for dual enrollment and found no better outcomes in general for the dual enrollment students. However, further analysis indicated that the students who took a rigorous college algebra class were 16 percent more likely to go to college and 23 percent more likely to earn a bachelor’s degree than similar students who did not take that particular class. These findings could call into question dual enrollment programs in which college courses are delivered on the high school campus. They also suggest that dual enrollment programs should focus on basic academic preparation instead of letting students choose from a range of courses. However, through CCRC’s extensive work in the field, the center’s researchers have learned that dual enrollment programs often face challenges that confound these seemingly straightforward approaches to program design. For example, one California program we studied served students from extremely disadvantaged backgrounds with little knowledge or experience of college. It was difficult to both recruit and retain these students and the program structure developed around efforts to engage them. Because many of the students lacked transportation, the program located the dual enrollment courses on the high school campus; many students said they could not participate if the courses were held at the college. Program staff also discovered that the key to retaining students in the program was offering courses in topics relevant to their lives, such as “Academic and Life Success” and “The Multicultural Journey.” The students found these classes challenging but meaningful, and once they were offered, retention increased. The hope is that even a high-school based college experience can create the foundation and momentum for students to eventually take the next step onto a college campus. Thus, while the new studies are important in helping clarify the program components that are associated with the strongest student outcomes, individual programs must always take into account the most effective ways to reach their students. Rather than adhering to a rigid blueprint for structure and delivery, program administrators should develop systems to measure student outcomes and use the resulting data to continually adjust and improve their dual enrollment programs. Hughes is the Assistant Director for Work and Education Reform Research at the Community College Research Center (CCRC) (http://ccrc.tc.columbia.edu), Teachers College, and a senior staff member of the National Center for Postsecondary Research.

Date of this Version Collisions between large vertebrates and vehicles along roadways are an increasing concern, not only because of ecological consequences, but also because of associated economic and social costs. We used a large-scale, long-term data set comprising several databases from Utah to summarize and analyze these costs. The overall cost for 13,020 collisions from 1996 to 2001 in Utah was approximately $45,175,454, resulting in an estimated average per year cost of about $7,529,242 and a mean collision cost of $3,470. These figures include human fatality costs of $24 million (53% of total costs); vehicle damage costs of $18 million (39%); loss of deer, valued at $2.7 million (6%); and human injury costs of $1 million (2%). Cost-benefit analyses have shown that mitigation efforts, which are prioritized based on road-kill data, can produce positive net economic gains and also increase driver safety.

Improvised lamp made of a dynamo and bike lamp The three main parts that make this improvised lamp are a bike lamp, a dynamo and two handles one of which is movable and the other fixed. The fixed handle is used for guiding the lamp, while the movable handle on the right is used as a crank. Fast speed movements of the crank make dynamo act as a power supply for the bike lamp, which enables the creation of light beams. Although it seems primitive, this invention was of extreme help for the people during the years of war. This simple, improvised lamp is another in a series of proof of human ingenuity and perspicacity, even in extremely difficult circumstances.

Poisoned candy myths |This article needs additional citations for verification. (March 2008)| The poisoned candy myths are urban legends that malevolent individuals could hide poison or drugs, or sharp objects such as razor blades, needles, or broken glass in candy and distribute the candy in order to harm random children, especially during Halloween trick-or-treating. Development of the candy tampering myth Several events fostered the candy tampering myth. The first event took place in 1964, where an annoyed Long Island, New York housewife started giving out packages of inedible objects to children whom she believed were too old to be trick-or-treating. The packages contained items such as steel wool, dog biscuits, and ant buttons (which were clearly labeled with the word "poison"). Though nobody was injured, she was prosecuted and pleaded guilty to endangering children. The same year saw reports of lye-filled bubble gum being handed out in Detroit and rat poison being given in Philadelphia. The second milestone in the spread of the candy tampering myths was an article published in the New York Times in 1970. This article claimed that "Those Halloween goodies that children collect this weekend on their rounds of ‘trick or treating’ may bring them more horror than happiness", and provided specific examples of potential tamperings. In 2008, candy was found with metal shavings and metal blades embedded in it. The candy was Pokémon Valentine's Day lollipops purchased from a Dollar General store in Polk County, Florida. The candy was determined to have been manufactured in China and not tampered with within the United States. The lollipops were pulled from the shelves after a mother reported a blade in her child's lollipop and after several more lollipops with metal shavings in them were confiscated from a local elementary school. Debunking the myths Over the years various experts have tried to debunk the various candy tampering stories. Among this group is Joel Best, a University of Delaware sociologist who specializes in candy tampering legends. In his studies, and the book "Halloween Sadism: the evidence", he researched newspapers from 1958 on in search of candy tampering. Of these stories, fewer than 90 instances might have qualified as actual candy tampering. Best has found five child deaths that were initially thought by local authorities to be caused by homicidal strangers, but none of those were sustained by investigation. False claims of stranger poisoning In 1970, a 5-year-old boy from the Detroit area found and ate heroin his uncle had stashed. The boy died following a four-day coma. The family attempted to protect the uncle by claiming the drug had been sprinkled in the child's Halloween candy. In a 1974 case, Timothy O'Bryan, an 8-year-old boy from Deer Park, Texas, died after eating a cyanide-laced package of Pixy Stix. A subsequent police investigation eventually determined that the poisoned candy had been planted in his trick-or-treat pile by the boy's father, Ronald Clark O'Bryan, who also gave out poisoned candy to other children in an attempt to cover up the murder. The murderer, who had wanted to claim life insurance money, was executed in 1984. Media and the myth Despite the falsity of these claims the news media promoted the story continuously throughout the 1980s, with local news stations featuring frequent coverage. During this time cases of poisoning were repeatedly reported based on unsubstantiated claims or before a full investigation could be completed and often never followed up on. This one sided coverage contributed to the overall panic and caused rival media outlets to issue reports of candy tampering as well. By 1985, the media had driven the hysteria about candy poisonings to such a point that an ABC News/Washington Post poll that found 60% of parents feared that their children would be injured or killed because of Halloween candy sabotage. - "In recent years, there have been reports of people with twisted minds putting razor blades and poison in taffy apples and Halloween candy. It is no longer safe to let your child eat treats that come from strangers." –Ann Landers - "Somebody's child will become violently ill or die after eating poisoned candy or an apple containing a razor blade." –Dear Abby Unlike poison, there have been many incidents of sharp objects, including razor blades, being found in candy and other food products. In some cases, the blades were placed in the candy intentionally, but other cases were determined to be accidental. - "Deadly 'Tricks' Given Children in 3 States". The Milwaukee Journal.

NIH Research Matters April 20, 2009 Overlooked “Brown Fat” Tied to Obesity Scientists have thought that adults lack a type of fat called brown fat. New research shows that not only do adults have it, but it may play an important role in weight control. There are a least 2 different types of fat. Our bodies store energy primarily as white fat. When you consume too many calories, your body turns the excess into white fat. To lose weight, you generally have to use more energy than you take in, which makes your body tap into its stores and break down the white fat for energy. Brown fat helps to maintain body temperature by burning up chemical energy to create heat. It's found in small mammals like rodents throughout their lives. Human infants have it when they're born, but we lose brown fat as we age. By adulthood, researchers thought, our brown fat was essentially nonexistent. However, it's been difficult to actually measure brown fat. A team of scientists at several institutions in Boston set out to measure brown fat directly. They detected uptake of a labeled sugar molecule in whole-body scans that used an imaging system called positron-emission tomography and computed tomography (PET-CT). Cells that take up the sugar are metabolically active. In fat tissue, that indicates the presence of brown fat. The team, led by Dr. C. Ronald Kahn at the Joslin Diabetes Center, was partly supported by NIH's National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK).The researchers analyzed almost 2,000 patients for the presence of regions of brown fat that were at least 4 mm in diameter. In the April 9, 2009, edition of the New England Journal of Medicine, they reported that they detected brown fat in 76 of 1,013 women (7.5%) and 30 of 959 men (3.1%). Women also had more brown fat tissue and higher levels of sugar uptake. The most common area in which brown fat was detected was a region of the neck. Notably, the less brown fat tissue the researchers detected, the higher the body mass index (a ratio of weight to height) tended to be, especially in older people. That suggests a potential role of brown fat in adult human metabolism. Two companion papers published in the same journal issue complemented these findings. In one, a research team in the Netherlands reported detecting brown fat tissue activity in 23 of 24 men during cold exposure, but not at room temperature. The activity was significantly lower in the overweight and obese men than in the lean subjects. These results imply a role for brown fat in keeping the body warm. In the other study, a team from Sweden found that labeled sugar uptake increased by a factor of 15 in the cold. Suspecting the presence of brown fat, the researchers took tissue biopsies and demonstrated the presence of active brown fat. "Taken together, these studies show that a significant percentage of adults have active brown fat, and that it likely plays a role in regulating body temperature," says NIDDK researcher Dr. Francesco S. Celi, who wrote an accompanying editorial in the journal. "Stimulating this tissue to burn more energy may be a promising novel strategy for treating or preventing obesity." —Harrison Wein, Ph.D. - Weight-control Information Network: - Aim for a Healthy Weight: NIH Research Matters Bldg. 31, Rm. 5B64A, MSC 2094 Bethesda, MD 20892-2094 About NIH Research Matters Editor: Harrison Wein, Ph.D. Assistant Editors: Vicki Contie, Carol Torgan, Ph.D. NIH Research Matters is a weekly update of NIH research highlights from the Office of Communications and Public Liaison, Office of the Director, National Institutes of Health.

The massive earthquake that rocked Chile in 2010 could have triggered a swarm of smaller quakes thousands of miles away in California, researchers suggest. The magnitude 8.8 earthquake that hit Chile last year struck just offshore of areas holding 80 percent of the country's population. The quake killed at least 521 people, injured about 12,000 more and damaged or destroyed at least 370,000 houses. Now it turns out Chile might not have been the only place this quake affected. "We now know that a very large earthquake like the 2004 Sumatra earthquake and the 2010 Chile quake can trigger seismic activity potentially at anywhere within the Earth, because the seismic waves from such major earthquakes are large enough to circle the entire globe," researcher Zhigang Peng, a seismologist at the Georgia Institute of Technology in Atlanta, told OurAmazingPlanet. Peng and his colleagues suggest the Chilean quake triggered four earthquakes with magnitudes of 2 or higher that shook California, with the largest of the group being a magnitude 3.5 quake that rattled the Coso Volcanic Field about 5,730 miles (9,220 kilometers) away, where several geothermal power plants are located. Although this area is one of the most seismically active regions in California and often plagued by small quakes, when the researchers estimated the chance of an earthquake swarm occurring there immediately following the Chilean earthquake, their calculations suggest there was a more than 99 percent chance the two seismic events were probably connected. The seismologists also detected a cluster of deep tremors along the Parkfield-Cholame section of the San Andreas Fault that also appeared to be influenced by the Chilean quake about 5,820 miles (9,360 km) away. That section of the San Andreas was the site of possibly the largest quake on that fault in the last few centuries, the 1857 Fort Tejon earthquake, a magnitude 7.9 temblor. So how might one quake help set off these others? The researchers suggest the Chilean quake could have sent off so-called "love waves" horizontal surface movement that would have traveled from their epicenter all the way to California, pushing already stressed faults over the edge. "Earthquakes talk to each other," Peng said. "Many scientists have found that when a large earthquake occurs, it will trigger numerous earthquakes, mostly around the previous one, which are known as aftershocks. Some of them could be potentially dangerous." But whether or not large earthquakes can trigger other large earthquakes from far away is still an unanswered question. "So far we have found much evidence that large earthquakes could trigger small earthquakes at long-range distances," Peng said. "We have yet to see a damaging earthquake triggered at very large distances." Seeds of earthquakes One might also ask if the small tremors these distant quakes set off might relieve pressure on a fault, thus preventing or delaying larger quakes in the future. However, "since most of triggered earthquakes are small, then the built-up pressure in other faults are not relieved at all," Peng said. "However, it is possible that those triggered earthquakes could continue for a while, and may even lead to large earthquakes at later times." These findings might help scientists better understand how the seeds of earthquakes are planted, and how quakes interact with each other across long distances. "We can now calculate the stress perturbations from distant earthquakes such information is crucial to understand how earthquakes are triggered," Peng said. "We are still far from applying it to accurately predicting earthquakes. However, our study, together with others, could be used to improve our understanding of earthquake physics." "We can now calculate the stress perturbations from distant earthquakes," said researcher David Hill at the U.S. Geological Survey at Menlo Park, Calif. "Such information is crucial to understand how earthquakes are triggered. We are still far from applying it to accurately predicting earthquakes. However, our study, together with others, could be used to improve

TEN-month-old Ruby can speak just three words but scientists believe babies of her age can show sympathy. The ability to display sympathy was previously thought to start at 18 months but research has found it begins as early as 10 months. Even non-verbal infants show sympathy for victims of aggression, according to research published in PLOS ONE journal. Tuning into the emotional states of others "may function as a foundation for full-fledged sympathetic behaviour later on", the scientists said. Mother-of-two Leanne Roberts believes babies "go out in sympathy" when they see other babies upset: "At mothers' group if one of them cries, it can set a couple of them off." She said Ruby already demonstrates tenderness and an ability to comfort.

SEPTEMBER 17* - Constitution Day & National POW/MIA Recognition Day Constitution Day (or Citizenship Day) is an American federal observance that recognizes the ratification of the United States Constitution and those who have become U.S. citizens. It is observed on September 17, the day the U.S. Constitutional Convention signed the Constitution in 1787. The law establishing the holiday was created in 2004 with the passage of an amendment by Senator Robert Byrd to the Omnibus spending bill of 2004. Before this law was enacted, the holiday was known as "Citizenship Day". In addition to renaming the holiday "Constitution Day and Citizenship Day," the act mandates that all publicly funded educational institutions provide educational programming on the history of the American Constitution on that day. In May 2005, the United States Department of Education announced the enactment of this law and that it would apply to any school receiving federal funds of any kind. This holiday is not observed by granting time off work for federal employees. When Constitution Day falls on a weekend or on another holiday, schools and other institutions observe the holiday on an adjacent weekday. This was the case in 2005, when Constitution Day was generally observed on Friday, September 16 and 2006 when the holiday was observed on Monday, September 18. Universities and colleges nationwide have created "U.S. Constitution and Citizenship Weeks" in order to meet the requirements of the law. For example, the Milwaukee School of Engineering (MSOE) has created a celebration week that includes "Constitution Trivia Contests", distribution of free copies of the U.S. Constitution, a campus & community fair (in which volunteer and community groups can share information with students), a web page with facts and links related to the Constitution and history of the United States.

World cereal production set to reach historic high in 2013 Serious food insecurity affects Syria, Central Africa, parts of West Africa 11 July 2013, Rome - World total cereal production is forecast to increase by about 7 percent
World cereal production set to reach historic high in 2013 Serious food insecurity affects Syria, Central Africa, parts of West Africa 11 July 2013, Rome - World total cereal production is forecast to increase by about 7 percent in 2013 compared to last year, helping to replenish global inventories and raise expectations for more stable markets in 2013/14, according to the latest issue of FAO's quarterly Crop Prospects and Food Situation report. The increase would bring world cereal production to 2 479 million tonnes, a new record level. FAO now puts world wheat output in 2013 at 704 million tonnes, an increase of 6.8 percent, which more than recoups the previous year's reduction and represents the highest level in history. World production of coarse grains in 2013 is now forecast by FAO at about 1 275 million tonnes, up sharply (9.7 percent) from 2012. World rice production in 2013 is forecast to expand by 1.9 percent to 500 million tonnes (milled equivalent) although prospects are still very provisional. Import forecasts, cereal prices Cereal imports of Low-Income Food-Deficit Countries for 2013/14 are estimated to rise by some 5 percent, compared to 2012/13, to meet growing demand. Egypt, Indonesia and Nigeria, in particular, are forecast to import larger volumes. International prices of wheat declined slightly in June with the onset of the 2013 harvests in the Northern Hemisphere. By contrast, maize prices increased, supported by continued tight supplies. Export prices of rice were generally stable. Food insecurity situations The report focuses on developments affecting the food security situation of developing countries. In its review of food insecurity hotspots, the report highlights the following countries, among others: In Syria, 2013 wheat production dropped significantly below average due to the escalating civil conflict leading to disruptions in farming activities. Livestock sector has been severely affected. About 4 million people are estimated to be facing severe food insecurity. In Egypt, civil unrest and dwindling foreign exchange reserves raise serious food security concerns. In Central Africa, serious food insecurity conditions prevail due to escalating conflict affecting about 8.4 million people in Central African Republic and Democratic Republic of the Congo. In West Africa, the overall food situation is favourable in most parts of the Sahel following an above-average 2012 cereal harvest. However, a large number of people are still affected by conflict and the lingering effects of the 2011/12 food crisis. In East Africa, although household food security has improved in most countries, serious concerns remain in conflict areas in Somalia, the Sudan, and South Sudan, with 1 million, 4.3 million and 1.2 million food insecure people, respectively. In Madagascar, damage caused by locusts and a cyclone is expected to reduce crop production in 2013, causing increased hunger, especially in the southern and western regions of the country. In the Democratic People's Republic of Korea, despite improved cereal harvest of the 2012 main season and the near normal outcome of the ongoing harvest of the 2013 early season, chronic food insecurity exists. An estimated 2.8 million vulnerable people require food assistance until the next harvest in October.

The number of people with the Norovirus winter vomiting bug has gone down for a second week, latest figures show.But experts say the 32% drop seen in the rate of confirmed new cases over the last week alone in England and Wales does not mean the problem has gone away. Infection rates always fluctuate and cases could easily rise again, says the Health Protection Agency (HPA). This season, a new strain called Sydney 2012, is responsible for most cases. This strain of the virus was first seen in Australia- where the norovirus season is lasting longer than usual as outbreaks continue into their summer. Experts are watching international patterns closely but cannot be sure what will happen next in the UK. The number of new cases are up 56% on the number reported this time last year, and the total lab-confirmed toll now stands at 4,407. For each confirmed new case experts estimate a further 288 cases are likely to go unreported. Norovirus symptoms and information: - Symptoms include vomiting and/or diarrhoea - You may also have a fever, headache and stomach cramps - Over-the-counter medicines can be useful in treating headaches and other aches and pains - Do not visit your GP surgery or A&E unit if you have it - If symptoms persist for more than three or four days, or if you have a serious illness, seek medical attention through contact with your GP - Wash hands thoroughly, particularly after using the toilet and before eating - Clean hard surfaces with detergent followed by disinfection with a bleach solution, paying particular attention to the toilet and surrounding area. During the two weeks up to 13 January 2013 there were 39 hospital outbreaks reported, compared to 33 in the previous fortnight, bringing the total of outbreaks for the season to 728. The highly contagious virus can be spread by contact with contaminated surfaces or objects, contact with a person who has the infection or through contaminated food and water. Experts advise anyone who thinks they may have the virus to stay away from hospitals, GP surgeries and care homes to avoid spreading it to people who may be vulnerable.

Hydraulic systems can use either of two methods of load control: the energy-loss method, in which flow to the actuator is set by valving, or the volumecontrol method, in which a variabledisplacement pump regulates flow. Most industrial hydraulic systems are designed using the energy-loss method. However, energy lost as heat can exceed that of the mechanical power produced by the system. For example, even well-designed electrohydraulic servovalve or proportional valve systems may convert 60 to 80% of input horsepower to heat. Some hydraulic system heat is desirable to bring fluid up to operating temperature. Cold hydraulic oil has a higher viscosity than warm oil. So maintaining an operating temperature of 100° F would cause sluggish operation and excessive pressure drop in a system designed to operate at 140° F. When a system begins operation on a cold winter morning, for example, the oil should be allowed to warm until it reaches a temperature where heat is generated at the same rate as system heat radiating into the atmosphere or other cooling medium. If heat generation exceeds the rate at which heat can be dissipated, the excess heat can initiate oil decomposition, form varnish on system component surfaces, and begin to deteriorate system seals. Excess heat sooner or later spells trouble for any hydraulic system. Too much heat breaks down oil, damages seals and bearings, and increases wear on pumps and other components. The solution to these problems is the inclusion of a properly sized heat exchanger as a component of the system. Heat is a form of energy that migrates from one region to another when a temperature difference (gradient) exists between the regions. Heat naturally flows from the hotter region to the cooler one. The rate of heat transfer is important in determining how much can be removed from a system within a given time frame. As long as it has a higher heat transfer rate, a physically smaller heat exchanger can remove heat from a system faster than one that is much larger. The defining equation for any heat exchanger is: q = U X A X ΔT where: q is the heat transfer rate, BTU/hr, U is the overall heat transfer coeficient, BTU/hr-ft2-° F, A is the heat transfer surface area, ft2, and Δ is the fluid temperature difference, °F. These three factors take varying forms, depending on the particular design of heat exchanger and the application involved. Inspecting the equation reveals that increasing any factor on the right increases heat transfer rate in direct proportion. Doubling the surface area in contact with the heated fluid doubles the heat transfer rate. Increasing temperature difference between the hydraulic oil and the coolant by 50% increases the heat transfer rate by 50%. Heat dissipates from a fluid system through natural and forced convection. Natural convection occurs as heat moves from system components into the surrounding atmosphere because of the temperature gradient. In smaller hydraulic systems, temperatures generally are lower than in larger systems, and heat transfer from the oil to tubing and other component surfaces often provides sufficient cooling. However, if natural convection cannot remove enough generated heat, a heat exchanger must be installed to control system temperature. The heat exchanger uses forced convection to remove heat. Another mode of heat transmission, radiation, may often occur, but its effect is small and usually can be ignored. Heat exchangers are available in 1-, 2-, and 4-pass configurations, Figure 1. These multiple passes result from dividers in the bonnets that mate with segmenting bars on the tube sheets to initially force the cooling medium (water) through only a fraction of the tubes. This causes the water to flow one, two, or four times the length of the heat exchanger before it leaves the outlet. Fluid can flow in laminar, transitional, and turbulent modes. When flow is laminar and at low velocities in a tube, there is little or no fluid movement immediately next to the tube wall. This layer of stagnant fluid hinders heat transfer and acts as insulation. Faster, turbulent flow has no smooth velocity gradient. The jumbled, tumbled flow pattern can disrupt much of the stationary fluid film. Built-in obstructions to flow, called turbulators, disrupt laminar flow, thereby improving heat transfer. Although these obstructions to flow increase pressure drop through the heat exchanger, the improvement in heat transfer more than compensates for the higher pressure drop. Shell-and-tube heat exchangers, Figure 2, have an outer flanged shell with end bonnets appropriately sealed to the shell ends. A precise pattern of tubing within the shell runs the length of the shell and terminates in end plates. Tube ends are fastened to the end plates, which seal each end of the shell. Cool water flows inside the tubes, and hot hydraulic oil flows around the tubes within the shell. The tubes that make up the tube bundle, or core, are arranged in geometric tube bundle patterns (square or triangular centerline spacing when viewed from the tube ends) to help promote turbulent flow. The tubes run through several baffle plates that provide structural rigidity and create a maze through which the hot fluid must flow. This flow pattern enhances heat transfer by forcing the hot fluid to flow perpendicular to the tubes and promoting laminar flow. Many tube bundles for hydraulic

When talking about geometric transformations, we have to be very careful about the object being transformed. We have two alternatives, either the geometric objects are transformed or the coordinate system is transformed. These two are very closely related; but, the formulae that carry out the job are different. We only cover transforming geometric objects here. We shall start with the traditional Euclidean transformations that do not change lengths and angle measures, followed by affine transformation. Finally, we shall talk about projective transformations. The Euclidean transformations are the most commonly used transformations. An Euclidean transformation is either a translation, a rotation, or a reflection. We shall discuss translations and rotations only. Therefore, if a line has an equation Ax + By + C = 0, after plugging the formulae for x and y, the line has a new equation Ax' + By' + (-Ah - Bk + C) = 0. If a point (x, y) is rotated an angle a about the coordinate origin t

Individual differences | Methods | Statistics | Clinical | Educational | Industrial | Professional items | World psychology | Mental health is a concept that refers to a human individual's emotional and psychological well-being. Merriam-Webster defines mental health as "A state of emotional and psychological well-being in which an individual is able to use his or her cognitive and emotional capabilities, function in society, and meet the ordinary demands of everyday life." According to the World Health Organization (WHO), there is no one "official" definition of mental health. Cultural differences, subjective assessments, and competing professional theories all affect how "mental health" is defined. In general, most experts agree that "mental health" and "mental illness" are not opposites. In other words, the absence of a recognized mental disorder is not necessarily an indicator of mental health. One way to think about mental health is by looking at how effectively and successfully a person functions. Feeling capable and competent; being able to handle normal levels of stress, maintain satisfying relationships, and lead an independent life; and being able to "bounce back," or recover from difficult situations, are all signs of mental health. Some experts consider mental health as a continuum. Thus, an individual's mental health may have many different possible values. Mental wellness is generally viewed as a positive attribute, such that a person can reach enhanced levels of mental health, even if they do not have any diagnosable mental illness. This definition of mental health highlights emotional well being, the capacity to live a full and creative life and the flexibility to deal with life's inevitable challenges. Many therapeutic systems and self-help books offer methods and philosophies espousing presumably effective strategies and techniques for further improving the mental wellness of otherwise healthy people. World Health Organization definition of mental healthEdit "Mental health has been defined variously by scholars from different cultures. Concepts of mental health include subjective well-being, perceived self-efficacy, autonomy, competence, intergenerational dependence, and self-actualization of one's intellectual and emotional potential, among others. From a cross-cultural perspective, it is nearly impossible to define mental health comprehensively. It is, however, generally agreed that mental health is broader than a lack of mental disorders." Mental hygiene conceptEdit Dr. William Glasser, a psychiatrist engaged in therapeutics and counseling, describes 'Mental Hygiene' in his book Mental Health or Mental Illness (1961), following the dictionary definition of hygiene as the establishment and maintenance of health, i.e. mental health. Currently, many mental health professionals focus less upon enhancing mental health than on treating psychological symptoms with psychoactive medications. Mental health, as a concept, is quite distinct from mental illness, and enhancement of mental health plays no part in what most mental health professionals actually do. Instead, the Western medical model relies primarily upon the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) or ICD-10 to diagnose and treat the symptoms associated with what they call mental illnesses and disorders. Physicians, including psychiatrists, and other health and mental health professionals and researchers, generally agree that an illness is likely present when a defined pathology can be found in brain tissue. Illness that directly arise in connection with such pathology are often neurological in nature; Parkinson's disease and Alzheimer's disease are two examples. When no known identifiable organic or physical pathology is present, as is often the case in patients diagnosed with depression, mania, neurosis, and other mental illnesses, the question arises as to whether it is correct to attribute the very real symptoms to scientifically defined causes, i.e. a specific pathology. To a degree, certain indicators, such as reduced thyroid function, support medical hypotheses such as the chemical imbalance theory. The DSM-IV defines and attributes mental illnesses to 'chemical imbalances', for which neuropsychiatric drugs are now widely (and in the view of some board certified psychiatrists, wrongly) prescribed. (See Glasser: WARNING--Psychiatry Can Be Hazardous To Your Mental Health (Harper-Collins, 2004) and Treating Mental Health as a Public Health Problem -- A New Leadership Role for the Helping Professions and Robert Whitaker: Mad In America: Bad Science, Bad Medicine, and the Enduring Mistreatment of the Mentally Ill (Perseus Publishing, 2002)) Opposition to biological psychiatryEdit Opposing viewpoints to biological psychiatry theories include those of anti-psychiatry advocates, who contend psychiatric patients do not necessarily have a mental illness, but in fact are individuals who do not ascribe to the conventional belief system, or consensus reality, shared by most other people in their culture. Dr. Glasser defines mental health as an entity completely separate from mental illness, explaining that as long as the Western medical model prevails, the mental health profession will be unable to affordably deliver the services many people need. Dr. Glasser asserts that the Public Health model is much better suited to delivering mental health than the prevailing medical model. According to some critics of the reigning medical model, such as Glasser, the Public Health model has been successfully delivering physical health to millions of people for hundreds of years. He explains how this model could be expanded into a low cost Public Mental Health Delivery model, one that could be put into practice easily by al

More than 1400 young people testing positive for chlamydia - From: News Limited Network - October 23, 2013 A STAGGERING number of young children are suffering from chlamydia, with more than 1400 girls and boys aged 12-15 testing positive for the sexually transmitted disease. And in a shocking reflection of the true extent of under-age sexual activity, researchers reported 10,300 children in this age group presented for testing over the past three years. The latest statistics on sexually transmitted diseases released at the Australiasian Sexual Health Conference in Darwin show a record number of 82,000 Australians had a positive chlamydia test last year. This is the largest number of cases ever recorded and makes the sexually transmitted disease the most notified infection or disease of any kind in Australia. University NSW expert Associate Professor David Wilson described the infection rate as "staggering". And he says it is just the tip of the iceberg with up to 500,000 Australians estimated to have the disease and not know it. Chlamydia can be symptomless but can cause pelvic inflammatory disease, is related to infertility and preterm births and its spread shows fewer people are having safe sex. It can be prevented by using condoms and can be treated using antibiotics. Epidemiologist Carol El-Hayek from the Burnet Institute says the high rate of chlamydia in children and young teens bears out evidence that the age of first sexual activity has been decreasing. In the 1950s the average age of first sexual activity was 18 but recent surveys have found almost one in three young people say they first had sex before they turned 16. Sexual health experts worry this younger age group has not had a chance to hear the safe sex message. Chlamydia is probably being picked up when doctors order routine tests if a girl comes seeking help after unprotected sex, Ms El-Hayek said. Other data presented at the conference shows 200,000 Australians are living with hepatitis B, up 9,000 in the last month with 400 people dying from the infection each year. More than 230,000 Australians have hepatitis C, up 5,300 in the last 12 months. There were 13,649 new cases of Gonnorhea diagnosed last year, mainly in gay men and Aboriginal and Torres Strait Islander populations. The number of syphilis cases increased by 1,534 last year. The good news is that introduction of the cervical cancer vaccine is behind a dramatic reduction in genital warts. Before the vaccine was given to school girls in 2007, 12 per cent of girls aged under 21 had genital warts; that has declined to just 1 per cent under the vaccination program. The number of girls aged 21-30 with genital warts has plunged from 12- 4 per cent. Queensland University of Technology's Professor Alan McKee says experts may need to change the way young men learn about sexually transmi

Why Ship Eggs and Not Fish?... Iron River National Fish Hatchery Explains! BY CAREY EDWARDS, IRON RIVER NFH displacement and packaged for shipping. Credit: USFWS The Iron River National Fish Hatchery (NFH) in Iron River, Wisconsin maintains approximately 4,000 adult lake trout and coaster brook trout. These fish are spawned each fall and eggs are collected for restoration purposes in the Upper Great Lakes. Eyed eggs are shipped to other entities, including federal, state and tribal agencies, in and out of the region. Why do hatcheries ship eggs? Not every hatchery is a brood facility, meaning that not every facility holds adults and completes the egg-taking process. These non-brood facilities need a source of fish or fish eggs to fulfill their mission and fish production goals. That is where the brood facility “takes their order” and plans for the amount of eggs and which strain will be given to the other facilities. At Iron River NFH, we rear certain strains for Great Lakes restoration. However, the strain that fish managers want for the south end of Lake Michigan is not always the particular strain of brood that Iron River NFH rears. Therefore, we also “receive” eggs from other facilities, to meet our production goals. This year 190,000 lake trout eggs were shipped to Allegheny NFH in Warren, Pennsylvania, while also providing 360,000 eggs for production needs at Iron River NFH. Almost 800,000 brook trout eggs in total were shipped to the U.S. Geological Survey, Genoa NFH, Redcliff Tribal Hatchery, Grand Portage Indian Community and Keweenaw Bay Indian Community, not including 60,000 eggs to meet goals at Iron River NFH. Instead of destroying surplus eggs, Iron River NFH was able to utilize 365,000 brook trout eggs by sending them to the Eastern Band of Cherokee Indians located in North Carolina. other entities in and out of the region. Credit: USFWS This past year Iron River NFH also received 1.85 million lake trout eggs from Sullivan Creek NFH in Brimley, Michigan and Saratoga NFH in

- Fairy and folk tales - Introduction of letters and foundations of word formation and reading - Form drawing - Arithmetic (four processes) - Science through nature stories - Recorder playing - Foreign languages - Physical education through games First graders learn through the imagination Young children are master imitators. That's why Waldorf early childhood educators model the behaviors they want their charges to emulate. But with the coming of the elementary school years, imagining becomes the means by which the child learns. The Waldorf elementary school teacher presents every lesson as a story that appeals to the students' imaginations. For example, arithmetic operations may be dramatized by the adventures of Polly Plus, Missy Minus, Danny Divide and Tommy Times. Writing comes in a similar way. A story (which is enacted by the teacher, never read) helps develop a strong ability to create their own pictures. For instance, the teacher may tell the tale of a sinuous snake that slithers through the grass or suns itself on a stone, giving the children a picture of the sound "S." The children come to know writing just as humankind developed it over the millennia, with ideograms or pictaforms that evolve into letters. What else you'll see—and what you won't see Teachers use many means other than stories to impart knowledge. Arithmetic lessons, for instance, may employ marching and hand clapping as the children count and keep time. What fun to discover the times tables as the children emphasize every third or fourth beat! Note the absence of textbooks in this description of the Waldorf classroom. While textbooks may make their way into the middle school, they can't come close to approaching the teacher's lively animation and heart connection to the student. The rhythm of the day The teacher starts the day by shaking hands with the child and looking him or her in the eyes. The eye is the traditional window into the soul, and the teacher strives to recognize each individual student as a soul making its way in the physical world. We begin Main Lesson, lasting two hours, with morning circle: exploring languages and the world of numbers, followed by a period of movement, song and verse. Main lessons are taught in blocks that last three to four weeks. First year subjects include form drawing (the basis for writing), arithmetic, writing and reading. The children retell the story previous day's story then each student works in their main lesson book using words, pictures and diagrams that reflect the lesson of the day. These books are a treasure containing all their work. Many of the illustrations on this Web site are from students' main lesson books. Mornings are also the time for reviewing previous lessons and learning art, foreign languages, handwork, movement and eurythmy, a movement program unique to Waldorf schools. Specialized subject teachers usually present these lessons, although the class teacher may accompany them. After a rest period, afternoons are more active and they may include some classes but primarily a time of imaginative play. Studies have shown that social, outdoor activity helps the young child learn to work and play in a group and focus in a classroom setting. Finally, a description of grade one isn't complete without a word on the class playground. The first grade has its own play area deep in the trees behind the upper play field. There, whether they're playing games or making proto-scientific discoveries of the layered qualities of mica, they're safe in an imaginative world suitable to their developmental stage.

This video from About.com will explain what the ASVAB is.See Transcript Transcript:What Is the ASVAB? Hello, this is Jessica with About.com, here to talk to you about the ASVAB Test. Definition of ASVAB Test The Armed Forces Vocational Aptitude Battery (ASVAB) is the most widely used multiple-aptitude tests in the world. It is given at over 14,000 schools and Military Entrance Processing Stations, also known as MEPS. The test measures strength and weaknesses as well as potential for future success, providing information for civilian and military occupations. It also helps to determine which branch of the military is best suitable for each applicant based upon their aptitude and knowledge. The ASVAB is a timed multiple-choice test that takes about three hours to complete. Practice tests and books as well as online help are available, and studying is recommended before taking the test. No cell phones, calculators or electronic devices other than the computer used to test on are allowed and tests will be monitored. Sections of the ASVAB Test The ASVAB is not an IQ test, nor is it a pass or fail exam. ASVAB Branch Requirements for the Army, Navy, Air Force, Marines and Coast Guard vary and details are readily available should you wish to delve deeper into a specific area. The ASVAB contains eight or nine separately timed sub-tests, depending on which version you take. Subjects include General Science, Arithmetic Reasoning, Word Knowledge, Paragraph Comprehension, Auto & Shop, Mathematics Knowledge, Mechanical Comprehension, Electronics Inf

By Greg Tylka, Department of Plant Pathology and Microbiology Iowa farmers produce soybeans profitably in fields infested with the soybean cyst nematode (SCN) by growing SCN-resistant soybean varieties that yield well and prevent large increases in SCN egg population densities. There are hundreds of SCN-resistant soybean varieties for Iowa. Almost all of the varieties contain SCN resistance genes from a single breeding line, called PI 88788. Because of widespread, repeated use of varieties with the same PI 88788 source of resistance, many SCN populations have developed increased reproduction on that type of resistance. It is no longer uncommon to see SCN females on roots of SCN-resistant soybean varieties in the Midwest (Figure 1). Figure 1. SCN females on roots of an SCN-resistant soybean variety with PI 88788 SCN resistance. How does increased SCN reproduction on soybean varieties with the PI 88788 source of resistance affect soybean yields and the buildup of SCN egg population densities (numbers) in the soil? Results of Iowa State University field experiments reveal the answers. Experimental results show PI 88788 resistance is still working Each year, SCN-resistant soybean varieties are studied intensively in nine experiments throughout Iowa as part of the Iowa State University SCN-resistant Soybean Variety Trial Program. The research is funded by the soybean checkoff through the Iowa Soybean Association. Since 2007, more than half of the fields in Iowa where variety trial experiments were conducted had SCN populations with elevated (greater than 10 percent) nematode reproduction on the PI 88788 source of resistance. The 10-percent level of SCN reproduction is a critical level above which plants are not considered resistant. Some of the SCN populations in the experimental fields had 35 to 50 percent reproduction on PI 88788. But despite the increased SCN reproduction, soybean varieties with the PI 88788 source of SCN resistance in the experiments usually yielded the highest. Also, SCN population densities did not increase dramatically on the resistant varieties in the experiments. These results were fairly consistent throughout the past five years (results available online at www.isuscntrials.info). Overall, the results indicate that SCN-resistant soybean varieties with the PI 88788 source of resistance are not “failing”. The resistant varieties are still producing profitable soybean yields and preventing large increases in SCN population densities. Because SCN is considerably more damaging in hot, dry years than in growing seasons with more moderate weather, soybean var

Surgery (Esophagus & Small Intestine) Operative treatment of esophageal cancer carries up to a 40% mortality rate and 10% five-year survival. Surgery is most effective for esophageal cancers in the distal half. Maintaining nutrition is extremely important; however, esophageal feeding tubes, colonic interpositioning, and feeding gastrostomies are each accompanied by high morbidity. Laser surgery can help to maintain an open passageway for nutrition. For carcinoid tumors less than 1 cm in diameter, local resection is the treatment of choice. If the tumor is larger than 1 cm, the resection should include regional lymph nodes from the mesentery. X = complete * = partial o = optio

Huanggutun Incident (Chinese: 皇姑屯事件; Japanese: Zhang Zuolin Assassination Incident (張作霖爆殺事件 Chosakurin bakusatsu jiken )) was an assassination plotted by the Japanese Kwantung Army that targeted Fengtian warlord Zhang Zuolin. It took place on June 4, 1928 at Huanggutun rail station near Shenyang in which Zhang's train was destroyed by an explosion. This incident was concealed in Japan at the time and was referred only as "満州某重大事件" (Manshuboujudaijiken A Certain Important Incident in Manchuria). Following the Xinhai Revolution of 1911, China dissolved in spontaneous devolution, with local officials and military leaders assuming power independent of control by the weak central government. In north China, the once powerful Beiyang Army split up into various factions after the death of Yuan Shikai in 1916. Zhang Zuolin, being the leader of the Fengtian clique, was one of the most powerful warlords as he managed to seize control of the three northeastern provinces of Manchuria. At the time of the First United Front in 1924, the foreign support in China was generally divided as below: The Fengtian clique's support from abroad was the Empire of Japan, which had vested economical and political interests in the region since the end of the Russo-Japanese War, and was interested in exploiting their region’s largely untapped natural resources. The Japanese Kwantung Army, based in the Kwantung Leased Territory also had responsibility for safeguarding the South Manchurian Railway, and thus had troops stationed in Manchuria, which provided material and logistic support for the Fengtian clique. The cooperation initially worked to the mutual benefit of both parties. Zhang provided security for the railroad and Japanese economic interests, suppressing Manchuria’s endemic banditry problem and allowing extensive Japanese investments. The Imperial Japanese Army assisted Zhang in the two Zhili-Fengtian Wars, including the suppression of the anti-Fengtian uprising by Guo Songling (a senior Fengtian clique general). However, Zhang just needed Japan's aid for consolidating and expanding his territory whereas Japan envisioned a future joint occupation of Manchuria with Zhang. After Zhang achieved his targets, he tried to improve relations with the United States and the United Kingdom, allowing both countries open access to the trade, investment and economic opportuni

MOWING EXPERIMENT EXOTECH DATA (FIFE)Entry ID: FIFE_MOW_EXO Abstract: Light radiation striking a vegetative canopy interacts with individual phyto-elements (i.e., leaves, stems, branches) and the underlying substrate. The interaction depends on light quality, radiative form (direct or diffuse), illumination incidence angle, vegetative component optical properties and canopy architecture. Radiation is reflected, transmitted or absorbed. Mowing, grazing, and... fertilization can affect the canopy architecture or optical properties of vegetation, thus changing the canopy reflectance. This study examined the response of spectral reflectance characteristics (using an Exotech radiometer) to canopies that were manipulated using simulated grazing and fertilization of plots. The spectral reflectance data set supports the original hypothesis of a curvilinear relationship between productivity and grazing intensity. Reflectances for the four MSS bands and the standard error for each are reported. These data were collected at two locations within the northwest quadrant of the FIFE study area during the growing season of 1987. Reflected radiation measurements were converted to radiances and reflectance factor. The reflectance factor is the ratio of the target reflected radiant flux to an ideal radiant flux reflected by an ideal Lambertian standard surface irradiated in exactly the same way as the target.

In all honesty, I’m not going to blog all the gory details of all the definitions of things that go into the definition of a stack. This leaves me with a problem I haven’t quite figured out how to solve: What do I show? The task seems so massive right now, but there must be a non-offensive way to sort of give the idea of a stack by being more precise than the general vague way people try to explain it, but without doing more than say 5 more posts on it (I also would like to avoid cheating, i.e. go through descent rather than just saying “a stack is a sheaf on a site”). So today we’ll jump back a little and try to figure out why one would care about stacks. Recall the Yoneda Lemma. Colloquially this says that if we have a (small) category, then the functor of points, which is by (note for us it’s contravariant) completely determines the object. So what is happening is that we are “testing” what the object looks like, and if we test it against everything, then we completely know what the object looks like. If we’re thinking about differential geometry, then by functor of points, we really mean “points”. Let be a smooth manifold in the category of smooth manifolds. Then we’ll test what the point-valued points look like. Well, apply the functor of points to a point,. Each map is completely determined by which point of the point goes to. It sounds silly, but this is just saying “the points of are the point-valued points”, which we already knew. Let’s think about this from a very classical algebraic geometry standpoint. Let’s work in the category of affine schemes. We call the -valued points of. This because if we have something like, then by -valued points we really mean what are the solutions to when can take values in. So if we think of it is the complex curve, or are the integer solutions (only trivial ones by Fermat’s Last Theorem). So scheme theoretically this tool is really cool. It groups all of this information into one package. In reality, we actually usually think of Yoneda in terms of the embedding it gives us. By identifying with the object (i.e. the functor represents in the usual sense of a representable functor) we get an embedding by the obvious thing. So our category is actually sitting inside the category of functors from to. To quickly recap in the language of schemes, given a scheme, we get a functor. But the other way around is not always true, i.e. not every functor is represented by a scheme. Here is where the notion of a stack (or algebraic space) might be nice. Sometimes it is really easy to write down what the functor of points should be for something. Now the question becomes, is this a scheme? Or maybe a better question should be does it matter if it is or is not a scheme? Exactly how loose do we allow the definition to get before we shouldn’t consider it as some sort of “geometric space”? Just a last quick example to show this really does happen. Suppose you want to figure out what the space of curves of genus looks like. Call this space. Then you can almost immediately write down that the functor of points for this space needs to be something like where is proper, smooth, and the fibers are curves of genus and we mod out by appropriate isomorphisms (maybe if we think about moduli later we’ll be more careful with that definition). This turns out to NOT correspond to a scheme. But it is still quite nice, and is in fact a stack. Moral of the story: If we think of schemes as a certain class of functors, it is very natural to come to

The Skoll World Forum is a proud media partner for the initiative, and you can find the whole series here. Adrienne Klasa is a journalist currently based in London, with a particular interest in the intersection between politics, business and international currents in sub-Saharan Africa. Adam Robert Green is a senior reporter at This is Africa, focusing on trade and investment, development policy, energy and social service delivery. As the continent awaits its agricultural revolution, This is Africa looks at the cutting edge ideas which could make the difference While the majority of the African population is heavily reliant on agriculture, the continent has lagged behind other developing regions in progressing this essential sector. Research and development specific to the continent’s varied ecosystems and crops has been chronically neglected, as has infrastructure and education to support farmers. As Harvard professor and Kenyan national Calestous Juma has argued: “Neglect of agriculture has been a defining feature of Africa’s economic policy over the last four decades.” But that may be changing. Public and private sector alike are now taking a renewed interest in agriculture, and this focus is not without basis: according to the African Development Bank, when agriculture stimulates growth it is twice as effective at reducing poverty than any other sector. Scientists are making advances in seed and fertiliser technologies, but creative solutions are also needed to improve market access and coordination, as well as to mitigate the impact of climate change. But which solutions have the potential to instigate real change? Here, This is Africa profiles some of the potentially catalytic innovations. As part of the drive to improve productivity, cutting edge scientific research methods are being leveraged to improve crop performance. In one example, food manufacturing giant Mars is assisting in the quest to boost the continent’s cocoa yields through genetics. Using its production base in Côte d’Ivoire, the world’s leading cocoa producer, Mars publicly released the cacao tree genome that the company’s agricultural research department mapped in partnership with the US Department of Agriculture and IBM in 2010, so that scientists everywhere can have access to it for their research. “The fact that we had this fundamental tool to help us in the breeding of water- and nutrient-efficient trees is a huge breakthrough for any commodity,” says Howard-Yana Shapiro, chief agricultural officer for Mars. “Our goal in the next generation is a yield of 1,500-2,000 kg per hectare, although the end target is much higher.” Mr Shapiro acknowledges the importance of improving farmers’ cocoa output simply because it makes good business sense to secure Mars’ supply chain well into the future – and to meet growing demands from emerging markets. “We had seen that cocoa production had stagnated at 450 kilos per hectare. You live in poverty if that is your production. If there was a similar scenario in corn, or wheat, or rice, nobody would grow it,” he says. “We need another whole Côte D’Ivoire [in terms of cocoa production volume] in 2020, because you have this sleeping giant called China waking up, you have India starting to develop a taste for chocolate.” Whereas most cocoa in Africa is produced for export as a cash crop, rice is a staple in many countries. But due to low productivity and growing demand, consumption far outpaces domestic production. Imported rice accounts for roughly 40 percent of local consumption, eating up billions in scarce foreign exchange. But here too, the outlook is improving. Paddy rice production growth in sub-Saharan Africa has shot up from 3.2 percent per year before the 2000–2007 rice crisis to 8.4 percent per year since, according to research by the Africa Rice Center. While 71 percent of this improvement can be explained by yield increase, 29 percent is accounted for by the expansion of the areas under cultivation – a complete reversal of pre-crisis figures, according to Marco Wopereis, deputy director general at AfricaRice. “This is evidence of increased use of technological innovation, such as improved varieties and better crop management in general,” he says. One management technique that has yielded notable results is the rice nucleus model pioneered by Olam Nigeria. As part of Nigeria’s bid to increase its domestic production of the staple up from 65 percent of consumption, the nucleus model combines the scale and quality assurance of a central commercial farm with an outgrower programme that engages small farmers. The nucleus farm currently has 20,000 farmers in its outgrower programme, and is on track to become the largest r

People with mental illnesses are 30 percent more likely to die from cancer, though cancer doesn’t affect them at a higher rate than those in the general population, according to a new study published in JAMA Psychology. Overall, psychiatric patients are significantly more likely to have metastasis—when cancer spreads to other organs—by the time they are diagnosed, as compared to their peers without mental disorders. The study was conducted in Australia, and even though Australians are covered by universal health care, patients with a mental illness are less likely to receive surgery—even for colorectal, breast, and cervical cancer, for which surgery is often the first line of treatment—and they tend to receive fewer chemotherapy sessions. Rates of Cancer Among the Mentally Ill Researchers at the Griffith Institute for Health and Medical Research in Australia examined the medical and death records of patients in Western Australia. They identified 135,442 new cases of cancer, of which 6,586 affected people with mental illnesses. Researchers found that although cancer affected psychiatric patients at a slightly lower rate than the general population, these patients had a 30 percent greater chance of dying from it. This was due in part to the fact that the cancer had spread to other parts of the body by the time they were diagnosed. Psychiatric patients are specifically more likely to die from terminal forms of colorectal, skin, prostate, and breast cancer. What's Causing this Discrepancy? Researchers couldn’t say with certainty why the mentally ill are dying from cancer more often than those without a history of mental disorders, but they identified these possible contributing factors: - Cancer goes unrecognized, especially in those with severe mental illnesses. However, scientists in Denmark (where autopsies are common) found few cases of undiagnosed cancer in schizophrenic patients. - People with mental illnesses receive poorer care or unequal access to appropriate care. - Diagnosis or screening is delayed, allowing the cancer to progress before treatment. The study authors also said that psychiatric patients are more likely to live in rural and/or poor areas, which may restrict their access to healthcare. Because the survivability of cancer is dependent on early detection and proper treatment, unequal access for psychiatric patients could cost them their lives.

Tallgrass prairie once covered 30 million acres in Iowa. That’s approximately 80 percent of the state. Grasses, like big bluestem and Indian grass reached heights of 10 feet, and over 200 species of wildflowers dazzled the eye. This ecosystem was home to hundreds of species of wildlife, including buffalo, elk, black bear, and wolves. Settlers quickly realized the soils produced by the tallgrass prairie were extremely fertile and were excellent for growing crops. In less than 100 years, the prairies of Iowa all but disappeared to give us the agriculture state of today. Because of this, only 1/10 of 1% of the native prairie survives in small plots scattered throughout the state. Visit Sandhill Prairie located at Chichaqua Bottoms Greenbelt for a good representation of what used to cover most of the state of Iowa. - www.tallgrass.org This site describes the national wildlife refuge located near Prairie City, Iowa.

- Indexed triangles means that the vertices in a mesh are referred to by index numbers. This is the scheme OBJ8 uses. The advantage of indexing is that if a single vertex is used by many triangles (that share a corner) you only have to include the vertex data once, and then use that data many times by index. (The savings from indexing depend on how often vertices are shared.) - Triangle strips are strips of triangles sharing common edges. Because triangles in strips share so many common vertices, they can be stored in a compact form, for a savings of almost 3x. Back in the old days, triangle strips were critical for performance (hence the presence of strips in the OBJ2 and OBJ7 formats). However with modern hardware, indexing is more efficient - the slight increase in data size (due to the index) isn't as expensive as the cost of specifying "we're done with one strip, start the next one". (Consider that if we use indexed triangles, we can submit all triangles in one batch - with strips, we need one batch per strip.) Thus OBJ8 uses indexing and doesn't provide any strip primitives. There is one other concept to be aware of: cache utilization. Graphics cards remember the last few vertices they processed, so if a mesh repeats a vertex shortly after using it, the graphics card can save work. Triangle strips naturally use a cache somewhat well because vertices occur in close succession. Strips and DSF DSF allows for triangle strips (and triangle fans) as a space-saving measure. Even with indexing, the indices can be compressed if strips and fans are used, and with DSF, file size was a v

Only 1 in 5 Americans Getting Recommended Amounts of Exercise (ATLANTA) -- Not enough of us are getting the right amount of exercise, according to a weekly report from the Centers for Disease Control and Prevention. The CDC's Morbidity and Mortality Weekly Report says only about 20 percent, or one in five, U.S. adults are meeting the federal government's recommendations for physical activity, which includes aerobic and muscle strengthening components. Government health officials recommend adults get at least 2.5 hours a week of moderate-intensity aerobic activity such as walking, or one hour and 15 minutes a week of vigorous-intensity aerobic activity, such as jogging or a combination of both. The recommendations also call for muscle strengthening activities such as push-ups, sit-ups or lifting weights. The data, based on self-reported information from an annual phone survey by state health department, shows that 50 percent of U.S. adults are getting the recommended amounts of aerobic activity, and 30 percent are engaging in strength training. “Although only 20 percent of adults are meeting the overall physical activity recommendations, it is encouraging that half the adults in the United States are meeting the aerobic guidelines and a third are meeting the muscle-strengthening recommendations,” said Carmen D. Harris, M

Studying for long hours every day can take a toll on you in more ways than one. Depending on how you are sitting you could experience back aches, neck aches or wrist aches from the keyboard, but one of the ways to get tired really fast while studying is to stare at your computer screen or text book without taking a break. When you work on your computer you automatically blink less due to concentration; the same when reading. This can lead to dry, scratchy, itchy or watery eyes, fatigue, headache and even blurry vision. You could experience what is called CVS or Computer Vision Syndrome. So how can you make your study time less stressful? Follow what is referred to as the “20/20/20 Rule”. By following this simple rule you can help alleviate tiredness and eye strain. Every 20 minutes, stop and look 20 feet away for 20 seconds. This gives your eyes a break, forces you to blink and readjusts your vision. If you are a contact lenses wearer this is even more important. If you have glasses, you may want to consider wearing those while studying versus wearing your contacts as contacts may dry your eyes out even more if you are focusing and not blinking. Did you know a person blinks on average of 12 times per minute? If you are staring at the computer it can be reduced to five times per minute. When you don’t blink your cornea dries and then when your eyes do blink they may burn and sting and create tears as it is trying to hydrate your cornea again. After a while, your vision starts to blur, you get tired and decide to turn off the computer or put away the books and study another day. Then the process starts all over again the next time you start to study. It’s a vicious cycle. So how do you make yourself remember to stop every 20 minutes and look away? You could set an alarm on your phone or there are programs you can download that interrupt your computer work and remind you to stop and take a break. You can download programs such as Evo, Wor

A new research reveals that short sessions of exercise can help in keeping stress at low levels on cell aging, which is a very helpful method in keeping stress at bay. As per findings published online in the May 26 issue of PLoS ONE, vigorous physical exercise amounting to as minute as 14 minutes every day, three day for each week, would be sufficient to bring in that protective effect. The plain advantage is reflected from exercise's effect on the span of tiny pieces of DNA that is known as telomeres. These telomeres function, effectively, such as molecular shoelace tips that grasp the whole thing collectively, so as to keep genes and chromosomes stable. Researchers consider that telomeres are inclined to cut down over time in response to pressure, leading to an increasing risk for heart disease, diabetes and ev

Teas, both green and black, have potent anti-cancer effects against a wide range of tumours, says a new study led by the US Department of Agriculture that adds to an ever growing body of science behind the compounds. "These findings extend related observations on the anticarcinogenic potential of tea ingredients and suggest that consumers may benefit more by drinking both green and black teas," wrote lead author Mendel Friedman from the USDA. The health benefits of tea ranging from a lower risk of certain cancers to weight loss, and protection against Alzheimer's, have been linked to the polyphenol content of the tea. Green tea contains between 30 and 40 per cent of water-extractable polyphenols, while black tea (green tea that has been oxidized by fermentation) contains between 3 and 10 per cent. Oolong tea is semi-fermented tea and is somewhere between green and black tea. The four primary polyphenols found in fresh tealeaves are epigallocatechin gallate (EGCG), epigallocatechin, epicatechin gallate, and epicatechin. Friedman and his co-workers from Keimyung, Uiduk, and Yeungnam Universities in South Korea investigated the ability to induce cell death in human cancer and normal cells nine green tea catechins, three black tea theaflavins, and theanine extracted using either an as aqueous and or an ethanol(80 per cent)/water method. "Because tumour promotion may be the only reversible event during cancer development, its suppression is regarded as an effective way to inhibit carcinogenesis," said Friedman. The researchers repo

Event Bubbling and Event Propagation: Demo Question: What is event bubbling? The concept of event bubbling was introduced to deal with situations where a single event, such as a mouse click, may be handled by two or more event handlers defined at different levels of the Document Object Model (DOM) hierarchy. If this is the case, the event bubbling process starts by executing the event handler defined for individual elements at the lowest level (e.g. individual hyperlinks, buttons, table cells etc.). From there, the event bubbles up to the containing elements (e.g. a table or a form with its own event handler), then up to even higher-level elements (e.g. the BODY element of the page). Finally, the event ends up being handled at the highest level in the DOM hierarchy, document element itself (provided that your document has its own event handler). The term event propagation is often used as a synonym of event bubbling. However, strictly speaking, event propagation is a wider term: it includes not only event bubbling but also event capturing. Event capturing is the opposite of bubbling (events are handled at higher levels first, then sink down to individual elements at lower levels). Event capturing is supported in fewer browsers and rarely used; notably, Internet Explorer prior to version 9.0 does not support event capturing. Demo: click any cell in the table and watch the click event bubbling! In this demo, | onclick event handlers change the background color of their respective elements. The event handlers are defined at four levels: (1) the document body <BODY onclick="handleBODY()"...> (2) the table element: <TABLE id=tb1 onclick="handleTABLE(event,this.id)"...> (3) table row elements: <TR id=tr1 onclick="handleTR(event,this.id)"> (4) individual table cells: <TD id=td11 onclick="handleTD(event,this.id)"> When you click inside table cells, event handlers at the lowest level (4) are triggered first, followed by event handlers at higher levels (3), (2), (1), in this order. Each event handler displays an alert message box telling you the level at which the click event is currently handled. The execution is paused until you dismiss the alert box. If you try to reset the demo by clicking the Reset button, the button's event handler function resetTable() works as expected (the background colors are reverted to white for the table and the entire page body). However, due to event bubbling, a higher-level event handler function is triggered too - which colorizes the entire page once again! To avoid unintended consequences like this, you can cancel event bubbling.

French Master Chefs in the 1930s 12 August 2013 - 30 June 2014 Room 31: case display by Florence Enid Stoddard In the late 1930s, Florence Enid Stoddard (1882-1962), an artist based for more than a decade in the United States where she made a living as a travelling portraitist and miniature painter, returned briefly to Britain and gained access to some of London’s great kitchens where she persuaded their busy maitre-chefs to sit for her. Armed with a list of French phrases with which to pose her sitters, she produced lively pencil studies of five of the leading chefs of the time, and a sixth of the long-serving head waiter at Simpsons in the Strand. It is unclear whether this set was commissioned for publication or a personal undertaking that Stoddard intended to exhibit in order to promote her work as a jobbing portraitist when she returned to America. In 2012 this group of drawings, together with accompanying archival material, was generously donated to the Gallery by the artist’s great-niece Christine Hayes and this display provides a first opportunity to showcase this intriguing acquisition and to introduce three of its chefs, Eugène Herbodeau at the Carlton, François Latry at the Savoy and Paul Henri Poupart at Buckingham Palace. These men, and their compatriots Arsène Avignon at the Ritz and Marcel Percevault at Claridges (not displayed), were successors to the great culinary expert Georges Auguste Escoffier (1846-1935). Where he led the way in gastronomie, they followed, promoting and celebrating French haute cuisine during the 1920s, through the years of depression, and into the period leading up to the Second World War. They presided over some of London’s busiest

Why Ernie Davis Matters Dr. Yanek Mieczkowski chairs the History Department at Dowling College. A specialist in post-World War II U.S. history, he is the author of Gerald Ford and the Challenges of the 1970s (2005) and The Routledge Historical Atlas of Presidential Elections (2001). Please visit his website featuring a biographical essay on Ernie Davis, www.erniedavishistory.com. “The Express,” which opened nationwide October 10, profiles Ernie Davis, who in 1961 became the first African-American to win the Heisman Trophy. Davis might seem an odd subject for a movie. He is little-known. Despite a stellar college football career, no NFL record books mention him. But he is a symbol of a time, and his life offers enduring lessons in humanity and courage. A spectacular athlete at Syracuse University, Davis followed in the footsteps of his idol, Cleveland Browns star Jim Brown, wearing the number Brown made legendary, 44. The halfback Davis (nicknamed “The Elmira Express,” reflecting his speed, locomotive-like power, and Elmira, New York roots) helped the Orange to a national title and broke Brown’s records, rushing for 2,386 yards and scoring 35 touchdowns. By capturing the Heisman, Davis succeeded where Brown could not; in 1956, Brown—who complained of racial polarization in college football—placed only fifth in Heisman voting, despite a standout senior year at Syracuse. What a difference five years made. Winning the Heisman during the civil rights era, Davis represented the hopes of a new generation of African Americans. Just months before Davis won, for example, activists engaged in “Freedom Rides” that helped to integrate southern bus stations and buses. But Davis was more than an athlete or civil rights pioneer. Friends found his personal qualities—his innate kindness and modesty—far more impressive than his sporting feats or fame. “He was obviously a marvelous athlete, but he was an even better person,” said Jack Moore, Davis’s co-captain on their high school basketball team. Davis’s thoughtfulness touched many. Once, at a high school dance, a big, drunken student tried to start a fight with Davis’s friend Bob Hill, who was much smaller. “Ernie saw it,” Hill remembered, and he quietly pushed the student aside, saying, “Let’s not have any of that, because he’s a friend of mine.” On another occasion, a boy tried out for the football team but knew so little about the game that he put his shoulder pads on backwards. Players teased him, but Davis walked over, introduced himself, and helped him to wear the equipment properly. In college, Davis remained humble even as his gridiron fame grew. John Mackey, a future NFL great who roomed with Davis, recalled one evening when they planned to see a movie. At the theater, a lady begged them for spare change for food. Davis gave her his money and convinced Mackey to do likewise. “We never did see the movie because we were out of money,” Mackey said. “We wound up going back to the dorm. But that was Ernie. Always generous. Always looking out for others.” When Davis graduated in 1962, the Cleveland Browns made him the nation’s number-one draft pick, planning to pair him with Brown in the backfield. They would comprise football’s greatest running attack. But during the summer, Davis started feeling strangely tired, and his gums bled. Eventually, doctors gave the grim diagnosis: leukemia. Davis remained upbeat, exercising and even practicing with the Browns, although he never got into a game. He had long aspired to play professional football, but that dream went unfulfilled. Yet Davis faced his illness bravely. John Wooten, a Cleveland player, said he never heard Davis complain: “He always spoke in terms of being okay, coming back. He was so high-spirited. In all these years, I’ve never seen anyone like this kid. He was special, indeed.” To the end, Davis remained gracious. Before being hospitalized for blood transfusions, he asked his Browns roommate, Syracuse classmate John Brown, to tell friends he was “out of town” to ease their worries about him. On May 16, 1963, Davis visited Browns owner Art Modell at his office. His neck visibly swollen, Davis apologized for his medical expenses and promised to make a comeback. Two days later, at age 23, he died. Tributes poured in. President John Kennedy called Davis “an outstanding young man of great character” and “an inspiration to the young people of this country.” Davis’s Syracuse coach, Ben Schwartzwalder, said, “When you talk about Ernie Davis, you’re treading on hallowed ground. We always thought he had a halo around him, and now we know he has.” The lessons of Ernie Davis’s life resonate, especially today, whenever sports fans see athletes involved in drug scandals or run-ins with the law. They would do well to remember Davis, and maybe the movie will help. “The Express” was almost a superhuman athlete, but his humanity left the deepest impact. More than an African-American star in the civil rights era, Davis was, said John Brown, “a genuine gentle man as well as a gent

Study: Sixty percent of teens notice calorie postings Chain restaurants are required to post the calorie content of their offerings on menu boards in a prominent way in some major American cities (including my fair but fat city of Philadelphia). The new health care reform law, signed last year, will enforce such labeling nationally. Many health experts support this public policy, saying it will help consumers make better informed food choices. There are already efforts to evaluate if calorie labels make a difference. Some studies showed reductions in intake, some showed no measurable effect. A new study, led by Brian Ebel, and published in the International Journal of Obesity, compared kids’ fast-food choices in two low-income communities: in New York City, where calorie labeling became mandatory in 2008, an in Newark NJ, were calories are not posted. Here are the main findings: • 349 kids, aged 1 to 17 years, were included in the study. The vast majority of these kids (90 percent) were from ethnic or minority groups • Many of the NYC adolescents (57 percent) reported noticing the calorie labels. 9 percent of participants said they took calorie posting into consideration (so of those that noticed the calorie postings, 16 percent said it played a role in food choices) • Customers’ receipts, show no effect on food purchases -- kids in the study ate on average 645 calories per meal at the participating fast-food joints (McDonald’s, Burger King, Wendy’s and KFC) before and after the labeling rules took effect • 35 percent of teens in the study reported they ate fast food six or more times a week • Asked about what influenced restaurant choice, the most important factors were ease, followed by location • When making food choices, the most important factor was taste (72 percent), followed by price (46 percent). Only about a quarter of the kids said they were concerned with their weight and tried to eat fewer calories • Three fourths of the kids had no clue about the daily caloric requirements of adults. The titles of most of the many reports on this study announced the ineffectiveness of calorie labeling on kids’ choices (CBS: Calorie Labels Don't Affect Kids' Fast Food Choices, Time: Calorie Counts on Menus: Apparently, Nobody Cares, Business Week: Calorie Labels Don't Affect Kid

| Antarctica Cruise | Books | | Forum | Site Map | FIDS / OAE's Chapter 3 - When the gale cleared we found that the pack had been driven in from the north-east and was now more firmly consolidated than before. A new berg, probably fifteen miles in length, had appeared on the northern horizon. The bergs within our circle of vision had all become familiar objects, and we had names for some of them. Apparently they were all drifting with the pack. The sighting of a new berg was of more than passing interest, since in that comparatively shallow sea it would be possible for a big berg to become stranded. Then the island of ice would be a centre of tremendous pressure and disturbance amid the drifting pack. We had seen something already of the smashing effect of a contest between berg and floe, and had no wish to have the helpless Endurance involved in such a battle of giants. During the 3rd the seal meat and blubber was re-stowed on hummocks around the ship. The frozen masses had been sinking into the floe. Ice, though hard and solid to the touch, is never firm against heavy weights. An article left on the floe for any length of time is likely to sink into the surface-ice. Then the salt water will percolate through and the article will become frozen into the body of the floe. Clear weather followed the gale, and we had a series of mock suns and parhelia. Minus temperatures were the rule, 21° below zero Fahr. being recorded on the 6th. We made mattresses for the dogs by stuffing sacks with straw and rubbish, and most of the animals were glad to receive this furnishing in their kennels. Some of them had suffered through the snow melting with the heat of their bodies and then freezing solid. The scientific members of the expedition were all busy by this time. The meteorologist had got his recording station, containing anemometer, barograph, and thermograph, rigged over the stern. The geologist was making the best of what to him was an unhappy situation; but was not altogether without material. The pebbles found in the penguins were often of considerable interest, and some fragments of rock were brought up from the sea floor with the sounding-lead and the drag-net. On the 7th Wordie and Worsley found some small pebbles, a piece of moss, a perfect bivalve shell, and some dust on a berg fragment, and brought their treasure-trove proudly to the ship. Clark was using the drag-net frequently in the leads and secured good hauls of plankton, with occasional specimens of greater scientific interest. Seals were not plentiful, but our store of meat and blubber grew gradually. All hands ate seal meat with relish and would not have cared to become dependent on the ship's tinned meat. We preferred the crab-eater to the Weddell, which is a very sluggish beast. The crab-eater seemed cleaner and healthier. The killer-whales were still with us. On the 8th we examined a spot where the floe-ice had been smashed up by a blow from beneath, delivered presumably by a large whale in search of a breathing-place. The force that had been exercised was astonishing. Slabs of ice 3 ft. thick, and weighing tons, had been tented upwards over a circular area with a diameter of about 25 ft., and cracks radiated outwards for more than 20 ft. The quarters in the 'tween decks were completed by the 10th, and the men took possession of the cubicles that had been built. The largest cubicle contained Macklin, McIlroy, Hurley, and Hussey and it was named "The Billabong." Clark and Wordie lived opposite in a room called "Auld Reekie." Next came the abode of "The Nuts" or engineers, followed by "The Sailors' Rest," inhabited by Cheetham and McNeish. "The Anchorage" and "The Fumarole" were on the other side. The new quarters became known as "The Ritz," and meals were served there instead of in the ward room. Breakfast was at 9 a.m., lunch at 1 p.m., tea at 4 p.m., and dinner at 6 p.m. Wild, Marston, Crean, and Worsley established themselves in cubicles in the wardroom, and by the middle of the month all hands had settled down to the winter routine. I lived alone aft. Worsley, Hurley, and Wordie made a journey to a big berg, called by us the Rampart Berg, on the 11th. The distance out was 7½ miles, and the party covered a total distance of about 17 miles. Hurley took some photographs and Wordie came back rejoicing with a little dust and some moss. "Within a radius of one mile round the berg there is thin young ic

Georg Moritz Ebers (Berlin, March 1, 1837 – Tutzing, Bavaria, August 7, 1898), German Egyptologist and novelist, discovered the Egyptian medical papyrus, of ca 1550 BCE, named for him (see Ebers papyrus) at Luxor (Thebes) in the winter of 1873–74. Now in the library of the University of Leipzig, the Ebers papyrus is among the most important ancient Egyptian medical papyri.

The kidnap and murder of two children and the rape of a seven-year-old in Delhi have exposed the fissures in India’s commitment to provide a safe and conducive environment for child development. School authorities should be responsible for the safety of children on school premises and ensure that only parents are allowed to take them home. While the police and the judiciary should be more sensitive to children’s needs, the responsibility of ensuring a safe childhood for them lies on the shoulder of every citizen. Gone are the days when parents and relatives tried to hush up crimes like rape. They have realised that by keeping quiet, they only embolden anti-social elements to harass women. If only the law-enforcement agencies can use the change in the thinking of rape victims and their relatives to bring the culprits to justice, crimes against women can be controlled sooner than later.

A NEMA standard defines a product, process, or procedure with reference to one or more of the following: nomenclature, composition, construction, dimensions, tolerances, safety, operating characteristics, performance, rating, testing, and the service
A NEMA standard defines a product, process, or procedure with reference to one or more of the following: nomenclature, composition, construction, dimensions, tolerances, safety, operating characteristics, performance, rating, testing, and the service for which the product(s) are designed. Each standard is identified by number and date; for more information on the naming conventions, see Reading NEMA standards. The Standards Development Process There are five basic steps taken to create a new standard, which are explained here. 1. Project initiation Before any significant work is done on a project, the NEMA section or duly authorized committee of the section must give their approval (by a simple majority). The section records project initiation on a Project Initiation Request (PIR) form. The Engineering department adds an entry into its standards database and begins tracking progress on the standard. 2. Developing the draft The section typically delegates development of a draft standard to a technical committee, subcommittee, or task force. For new standards, a new subcommittee or task force may be established. The section or technical committee designates the chair, who holds a meeting to develop a plan for completing the work. An outline of the standard may be developed and the work divided among the members. Most of the work involved in developing a standard is completed between meetings by one or more members. Completed sections of the draft standard are prepared and distributed to the entire group for review and comment. Comments are addressed by the group as a whole. Once the comments are resolved, the draft standard is revised and distributed again. The draft standard may go through several iterations until there is consensus in the group that the draft is ready to move on. It is now forwarded to the full technical committee for review and comment. Comments are compiled and addressed by the group that developed the draft. Once the technical committee’s comments have been satisfied, its members will decide if the draft is ready to ballot to the section (or voting classification). 3. Balloting (gathering comments) All proposed standards publications are provided in a uniform format, as defined in NEMA NS 1-2005. Prior to issuing, the letter ballot must be reviewed by NEMA Counsel. Votes from a section or voting class for a standards bulletin is generally taken by letter ballot with a 30-day window for response. All letter ballots allow member’s votes to be cast in the affirmative, in the negative, or as “not voting.” A NEMA member who manufactures the product is eligible to vote on standards pertaining to that product. Any member may change a vote within the voting period unless they waived the right to do so on the letter ballot, but no member may change a vote given by letter ballot after the voting period expires. A standard, when presented to any section or voting class for approval, requires the affirmative vote of at least two thirds of the votes cast in the affirmative or negative. In lieu of a letter ballot, a standard proposal may be approved at a section or voting class meeting, provided 100 percent of the section or voting class membership is present. Where there are votes accompanied by comments, the proposed standard and result of the letter ballot are referred to the technical committee or its delegated subcommittee within 30 days following completion of the letter ballot. If after due consideration the technical committee cannot resolve all negative comments of a successful ballot, the technical committee chairman submits the proposed standard to the Codes and Standards Committee (C&S), which may request written comments or oral presentations from both sides to assist in its review. A comment may be withdrawn or, at the option of the member, changed to an affirmative vote in writing. If there are no comments or the comments accompanying all negative votes on the letter ballot are withdrawn, the proposed standard is submitted to C&S. 4. Codes and Standards Committee approval All actions of sections and voting classes in approving, revising, reaffirming, or rescinding standards of the association are subject to the approval of C&S. In approving, disapproving, or reviewing NEMA standards, C&S acts only by the concurrent vote of a majority of its members given either at a m

Science — Not Politics — Should Shape the WIC Food Package With the farm bill and appropriations bills moving through Congress, the potato industry is pushing again to require the WIC program to add white potatoes to the limited list of foods it provides, contrary to what the nation’s leading nutrition experts recommend. Despite such lobbying campaigns in the past, Congress has never dictated the specific foods that WIC should provide — and it shouldn’t start now. WIC — the Special Supplemental Nutrition Program for Women, Infants, and Children — provides nutritious foods, counseling on healthy eating, and health care referrals to roughly 9 million low-income pregnant and postpartum women, infants, and children under age 5. WIC was never intended to provide a full range of foods; it’s a supplemental program, providing the key nutrients that nutrition scientists say are missing from the diets of low-income pregnant and nursing women, infants, and young children. Potatoes have never been part of the WIC food package. Following a multi-year, science-based process, the Agriculture Department (USDA) revised the WIC food package in 2009 to include fruits and vegetables for the first time — part of an effort to fight the national obesity epidemic. As the National Academy of Sciences’ Institute of Medicine recommended, USDA did not include white potatoes because that would provide no additional nutritional benefit: WIC participants already eat more than the recommended amounts of starchy vegetables. Allowing participants to use their WIC fruit and vegetable vouchers — which are for a fixed dollar amount of food purchases — to buy potatoes would not only lead to more starch consumption, but would leave less for foods that participants don’t eat enough of, such as dark green leafy vegetables. The states or districts of many members of Congress include firms that grow or process specific food items that those lawmakers often promote. Fortunately, policymakers on a bipartisan basis have agreed since WIC’s creation in 1972 that decisions on which foods to include in the WIC food package should be based on the best scientific evidence, rather than political pressure, and determined through a science-based process rather than dictated by Congress. In no small part, WIC’s well-documented success at improving birth outcomes and participants’ nutrition and health reflects Congress’ commitment to insulate WIC from political pressures and focus solely on promoting maternal and child health. Breaking that long-standing commitment now could undermine one of our most successful federal programs by substituting political pressures for sound scientific judgment.

An Information System for Plant-Insect Interactions in Four Subcatchments Of Mt. Isarog Natural Park Mount Isarog Natural Park (MINP) which is 10, 112 hectares wide has an abounding diversity of fauna and flora. The information that can be extracted from the natural resources in Mt. Isarog starting with the species behavior and interdependence, to profiling its gene sequences and determining plant compound content, globally renews the present Biology. These data must be converted into knowledge leading to a discovery of novel products and facts about the ecosystem that would benefit humans and the ecosystem itself. The Mt. Isarog’s Flora and Associated Arthropods’ Basic, Genomic and Spectroscopic Profile, Biological Behavior and Interdependence: An Information System (MIFAABGSBBI) basically documents the information obtained from MINP’s flora and associated arthropods through an efficient database management system encapsulated in an effectual web-based information system. Presently there is no online information system about Mt. Isarog species particularly flora and associated arthropods that records and provides detailed information about their biological features and behaviors. The information system will serve as an avenue for advanced researches about species interdependence, for food web diagrams are generated. Upon discovering an exceptional trait of species which depends on another particular species, their genomic and spectroscopic profile can be analyzed for comparative analysis.

Vinton G. “Vint” Cerf isn’t crazy about being called “the father of the Internet”—he insists that many people were involved in its invention. But he is the man who did the most to make it happen, writing the communication protocol for Arpanet (the “original” Internet developed by the Defense Department in the late 1960s) and codesigning the protocols (known as TCP/IP—Transmission Control Protocol/Internet Protocol) that allow computers everywhere to communicate with each other, giving us access to whole worlds of information. In 2005 Cerf (and longtime collaborator Robert Kahn) received the Presidential Medal of Freedom, the highest civilian honor given in the United States, in recognition of work that had placed them “at the forefront of a digital revolution that has transformed global commerce, communication, and entertainment.” Cerf has attributed his interest in the Internet in part to having lost much of his hearing when he was a child. Internet communication technologies, he points out, provide “a level playing field” for deaf people. Most recently Cerf has been involved with NASA’s Jet Propulsion Laboratory in helping move the Internet to other parts of the universe. The “Interplanetary Internet” will create new means of communication from planet to planet with the use of radio/laser technologies. An appreciation by Tim Berners-Lee, inventor of the World Wide Web and holder of the 3Com Founders Chair at the MIT Lab for Computer Science. Vint’s great success was to make the Internet a platform that is usable for all kinds of future technologies, without trying to second-guess what they might be. Thanks to this approach, I was able to design the Web on top of the Internet because it was a strong but plain foundation for things to come. In designing Web technology, we try to take the same approach. As a person, Vint has been not only an engineer but a leader. He has tried to ensure that both the Net and the community of developers evolve in a healthy way. This means both sound engineering and a positive impact on society.

In statistics, a probit model is a type of regression where the dependent variable can only take two values, for example married or not married. The name is from probability + unit. The purpose of the model is to estimate the probability that an observation with particular characteristics will fall into a specific one of the categories; moreover, if estimated probabilities greater than 1/2 are treated as classifying an observation into a predicted category, the probit model is a type of binary classification model. A probit model is a popular specification for an ordinal or a binary response model. As such it treats the same set of problems as does logistic regression using similar techniques. The probit model, which employs a probit link function, is

The figures and captions illustrating the articles were added by the editorial board of www.MuslimHeritage.com. * * *1. Prologue In 1120, a Muslim doctor was on his way to see his patient, the Almoravid ruler of Seville. By the side of the road he saw an emaciated man holding a water jug. The man's belly was swollen, and he was in obvious distress. Figure 1: Anatomy of the human eye from the treatise on ophthalmology by Hunayn Ibn Ishaq (10th century). (Source). "Are you sick?" the doctor asked. The man nodded. "What have you been eating?" "Only a few crusts of bread and the water from this jug." "Bread won't hurt you," said the doctor. "It could be the water. Where are you getting it?" "From the well in town." The doctor pondered a moment. "The well is clean. It must be the jug. Break it and find a new one." "I can't," whined the man, "This is my only jug." "And that thing bulging out there," replied the doctor, pointing to the man's midsection, "is your only stomach. It is easier to find a new jug than a new stomach." The man continued to protest, but one of the doctor's servants picked up a stone and smashed the jug. A dead frog spilled out with the foul water. "My friend," the doctor said to the patient, "look what you have been drinking. That frog would have taken you with him. Here, take this coin and go buy a new jug." When the doctor passed by a few days later, he saw the same man sitting by the side of the road. His stomach had shrunk, he had gained weight, and his color was back. Seeing the doctor, the man heaped praise on him (attributed to Ibn Abi Usaybi'a, 13th century). 2. The historical context While this demonstration of clear reasoning was taking place in Muslim Spain, medical practice in Christian Europe, hobbled by a mindset that would have seen the doctor's work as a challenge to divine will, offered the sick little more than prayers and comfort, rather than medicine or treatments. In the East, the spread of Islam, beginning in the seventh century CE, sparked the assimilation of existing knowledge and its development in all branches of learning, including medicine. Arab conquerors rapidly absorbed much from their new subjects. Arabic became to the East what Latin and Greek had been to the West—the language of literature and of the arts and sciences, the common tongue of learned men from the Rann of Kutch to the French border—and the Hajj, or pilgrimage to Makkah, brought hundreds of thousands of pilgrims together each year, facilitating the exchange of ideas, knowledge and books. Figure 2: Surgical Instruments from the treatise Kitab al-tasrîf liman ajaza an al-talîf fi al-tibb by Abu al-Qasim Khalaf Ibn Al-Abbas Al Zahrawi (Abulcasis). (Source). Recognizing the importance of translating Greek works into Arabic to make them more widely available, the Abbasid caliphs Harun al-Rashid and his son, al-Ma'mun, sponsored a translation bureau in Baghdad—the Bayt al-Hikmah, or House of Wisdom—starting in the late eighth century, that sent agents throughout Muslim and non-Muslim lands in search of scholarly manuscripts in every language. Rendered into Arabic, these precious documents established a solid foundation for the Muslim sciences, not least of which was medicine. As in Greece, medicine in the Muslim world was based on the theory of the four humors that had been advanced by the second-century Greek physician Galen. Each of the four universal elements that comprised the world—earth, air, fire and water—was associated with one of the humors—blood, phlegm, black bile and yellow bile—whose various mixtures defined the different temperaments. When the body's humors were in correct alignment, a person was healthy; when out of balance, he was sick. The task of the doctor, Galen wrote, was to restore this alignment by prescribing changes in diet, exercise or certain activities, or by taking other measures. For example, fever was caused by too much blood, and thus he prescribed bloodletting to remove the excess. However incorrect, Galen's essentially rationalist view of health and disease found favor in the East, where the Qur'an assured that "for every disease there is a cure." Thus Muslim physicians saw themselves as healers and preservers of health rather than passive witnesses to events with supernatural causes. While the translators in the House of Wisdom toiled, Muslim doctors developed the bimaristan—later simply maristan—the forerunner of today's hospital. Open to all, it welcomed patients to be treated for, and recover from, a variety of ailments and injuries, including mental illness. The larger maristans were attached to medical schools and libraries, where prospective physicians were taught, examined and, as today, licensed. The maristan became the cradle of Muslim medicine and the means of its disse

Few would disagree that clinical experience is critical for teacher development. Teaching is, after all, a demanding clinical practice, requiring teachers to orchestrate complex classroom interactions designed to help children learn. While clinical practice rests on a body of professional knowledge, ultimately teachers need to be able to put this knowledge to use in practice. Clinical experiences during professional education provide opportunities for teachers to develop and hone their craft. Grossman, P. (2010).

Inside folio Terences, the base text and commentaries varied far less than the front matter. Girolamo Scoto again set the standard in his 1545 edition. He provided three summaries for the action of each scene by three different humanist schoolmasters of note; the innovation was immediately copied by other publishers. Venturino Ruffinelli, who preferred his own layout and design (using comic-strip style illustrations), copied the 1545 text slavishly in 1546, but squeezed it into a page layout that had been designed for his 1539 edition of Gouveia's text. The basic layout problem in the case of Terence was that the text consists of short scenes with much back-and-forth badinage while the apparatus was typically very lengthy. As we have already noted, early printers of text with commentary had arranged the commentary for each scene in humanist-manuscript form all around the base text, creating a window or windows for the words of Terence. The resulting window-and-frame layouts are visually very lively, with each spread slightly different from the last, depending on the length of the commentary with respect to the text. (65) As the sixteenth century progressed, however, it became more usual to employ a simple two-column format that placed the base text of each scene first and the commentary afterwards, alternating but running continuously from column to column. The four columns on a spread owned variety and visual interest because the text of Terence was set in larger type and more generously leaded than the commentary, but the result was rarely as handsome as the older manuscript-style layouts. This two-column format took over because it was much easier to set, correct, revise, and reprint than a window-and-frame. Similarly, fewer and fewer options were exercised in ornamenting and illustrating the folio text as the century wore on. Virtually the only ambitious editions from this point of view are the 1545 Scoto and the 1553 Cesano. These books preserve something of the grace of earlier folios, with both the repeated author portraits and the scene-by-scene illustrations that had characterized some folio editions in the fourteen nineties and early in the sixteenth century. Illustrations of individual scenes disappeared entirely after the 1555, perhaps because the enthusiasm for their rediscovery had waned, and again in recognition of the fact that they added little beyond their ornamental value. Once they had been reduced to comic-strip style, moreover, they could not claim any real utility, even if they once had it. Author portraits persisted a little longer, but slowly faded away too. The single, nearly universal decorative element across the whole of the fifteenth and sixteenth century was the use of woodcut initials. To my knowledge, no new initial blocks were commissioned specifically for a Terence at any period. The initials were simply those a given printer had in stock or could borrow for the project at hand. The inevitable result was that schoolbooks tended to lag a few years behind the latest ornamental fashions. Iniziali parlanti ("speaking intitials" that included classical or biblical scenes) were fashionable in Venice from 1530 onward. They were duly employed for Terence, but their use in so workaday a text for school teachers was entirely pro forma. No scenes from the plays were ever incorporated into initials. (66) By the fifteen sixties the reused blocks typical in Venetian schoolbooks were so badly worn that their mythological stories can hardly be read. Terence would wait until the eighteenth century to merit truly pompous dress again. Open Bibliography (330 KB pdf) (65) It could cause typesetting problems, as described by Petrella 2006, 168-171. (66) Nardelli 1991 treats this phenomenon but does not offer examples from editions of Terence. The several series she attributes to Giolitto, nos. 1-17 and 27-34, and to Valgrisi, nos. 28-34, appear in Terences from several publishers of the period. On the copying of such woodcut initials in metal, see Mosley 1994 and 1998. Posted by admin on September 16, 2008 Tags: Chapter One

A new research is reported to have linked handheld laser pointers to eye injury risk. The study has been conducted by Dr. Martin Schmid, head of the retina unit in the department of ophthalmology at Lucerne Cantonal Hospital in Switzerland and colleagues. A laser pointer, a small laser device is used to highlight an object by directing a coherent source of light onto it. These pointers are available based on varied strength of the laser. The study report was recently published earlier this week in The New England Journal of Medicine. In addition, the study has highlighted a recent case involving a teenaged Swiss guy who accidently burned his eyes during his laser show. The report to experience a blurred vision in his eyes following the hit of the light beam in his eyes after it bounced back several times from the mirror. The boy’s left macula was diagnosed with subretinal hemorrhage and numerous tiny round scars in the pigment epithelium of the foveolar region of his right eye. The study has claimed that laser pointers may result in subretinal hemorrhage in macula. Moreover, the study has recommended adopting precautions while using laser pointer, especially children and teenagers.

Russel Wallace : Alfred Russell Wallace (sic) with New Guinea and Its Islands The only articles of commercial value procured from the interior of New Guinea are Mussoi bark and wild nutmegs. From the coasts and islands tripang or bêche-de-mer, mother-of-pearl shell, and tortoise-shell are all produced in abundance; and as they are all articles which command a ready sale, and at high prices, the trade is a very important one. The articles of less importance are pearls, birds of Paradise, sago (raw and in cakes), mats, palm-leaf boxes, and rice in the husk, or paddy. The destination of these articles is various, and but few reach Europe. The Mussoi bark, which contains an aromatic oil of a rather pungent odour, is sent to Java, where the natives buy it at a high price to rub on the skin as a remedy for rheumatic and many other diseases. It is probably from a tree of the cinnamon family. The tripang or sea-slug is all bought up by the Chinese, who are the only consumers of this repulsive article. The tortoise-shell is mostly bought by the Manilla traders, and I presume much of it is manufactured in the Philippines into combs and ornaments. Finely-spotted shells with much white in them are very highly esteemed, and command high prices. These the richer natives often keep in their houses as ornaments, and as articles always convertible into cash. Some tons of tortoise-shell must be produced annually on the coasts of New Guinea, and, as it is worth here 12s. to 20s. per pound, it becomes of itself an important trade. The pearl-shell and the wild nutmegs go all to European markets. Of the less important articles, the birds of Paradise are dispersed over the world; the greater part, I believe, now go to China. The pearls--which are few, and seldom fine--are also mostly bought by the Chinese. The sago and rice being very local productions, and the former being the staple food of the [[p. 128]] surrounding districts, they are a great medium of exchange over all the Papuan countries, a little being also taken to Ternate. The mats and palm-leaf boxes are in great demand all over the Moluccas. The goods with which these various products are purchased are not very diversified, the principal being bar-iron, calico, and thin red cottons from England, choppers made in Singapore or Macassar, Bugis cloths, cheap German knives and Chinese plates and basins, brass-wire, white and coloured beads, and silver coins. Arrack is indispensable in some districts, opium in others; but these are not in such general demand as the preceding. The trade is mainly carried on in native prahuws, a few small schooners only being now engaged in it from Ternate, Menado, Amboyna, and Macassar. They, however, form quite an unimportant feature in the trade of New Guinea, which is essentially native. A Malay prahuw is a vessel so unique as to deserve a brief description. It is a short vessel with bow and stern nearly alike. The deck (when it has one) slopes down towards the bows. The mast is a triangle, and consequently wants no shrouds, and, being low, carries an immense yard much longer than the vessel itself, which is hung out of the centre, and the short end hauled down on deck, so that the immense mainsail slopes upwards to a considerable height. A full-rigged prahuw carries a smaller similar sail abaft, and a bowsprit and jib. It has two rudders, one on each quarter, with a window or opening on each side for the tillers considerably below the deck. These vessels can only sail 8 points from the wind (so that it is impossible to make any way by tacking when the wind is ahead), and make their voyages only with the favourable monsoon--accomplishing, therefore, generally but one voyage a year. They are of all sizes, from l to 100 tons' burden, and are built--some with regularly nailed planks, some fastened only with rattans--but so ingeniously and securely as very well to stand a sea-voyage. When I first went from Macassar to New Guinea, a distance of 1000 miles, a small prahuw of about 10 tons which had not a single nail in its whole structure kept company with us all the way. The largest prahuws are from Macassar and the Bugis countries of Celebes and the island of Boutong. Smaller ones in great numbers sail from Ternate, Pidore, East Ceram, and Goram, which I shall have occasion again to allude to. I will now give a short notice of the chief districts of New Guinea and its islands, with the most important particulars relating to the trade carried on there, and the condition and character of the inhabitants. Great Geelvink Bay.--The centres of trade for this district are [[p. 129]] Dorey and the little island of Roe

NOAA uses data from a new current meter in New York harbor operated by New Jersey’s Stevens Institute of Technology. The system provides enhanced real-time information to mariners travelling through the nation’s second busiest port. The Stevens current meter measures the direction, speed, and volume of ocean currents in the harbor’s navigation channels, north of the Narrows between Brooklyn and Staten Island. Its data will be used in NOAA’s Physical Oceanographic Real-Time System (PORTS®) system, which delivers real-time environmental observations, forecasts and other geospatial information to mariners in 21 major U.S. harbors. The system makes maritime commerce more safe and efficient by giving ship captains instant measurements of the water levels and temperatures, and the direct

An African Agama lizard swings its tail upward to prevent pitching forward after a slip during take-off. Photo by Robert Full lab, UC Berkeley, courtesy of Nature. Leaping lizards have a message for robots: Get a tail! University of California, Berkeley, biologists and engineers - including undergraduate and graduate students - studied how lizards manage to leap successfully even when they slip and stumble. They found that lizards swing their tails upward to prevent them from pitching head-over-heels into a rock. But after the team added a tail to a robotic car named Tailbot, they discovered that counteracting the effect of a slip is not as simple as throwing your tail in the air. Instead, robots and lizards must actively adjust the angle of their tails just right to remain upright. UC Berkeley professor Robert Full discusses his research on lizards and geckos and how the biomechanical principles he and his students discovered apply to the design of robots. Courtesy of Nature & CiBER/UC Berkeley. "We showed for the first time that lizards swing their tail up or down to counteract the rotation of their body, keeping them stable," said team leader Robert J. Full, UC Berkeley professor of integrative biology. "Inspiration from lizard tails will likely lead to far more agile search-and-rescue robots, as well as ones having greater capability to more rapidly detect chemical, biological or nuclear hazards." Agile therapod dinosaurs like the velociraptor depicted in the movie Jurassic Park may also have used their tails as stabilizers to prevent forward pitch, Full said. Their tail movement is illustrated in a prescient chase sequence from the 1993 movie in which the animated animal leaps from a balcony onto a T. rex skeleton. "Muscles willing, the dinosaur could be even more effective with a swing of its tail in controlling body attitude than the lizards," Full said. Student involvement crucial to research Full and his laboratory colleagues, including both engineering and biology students, will report their discoveries online on Jan. 5 in advance of publication in the Jan. 12 print edition of the journal Nature. The paper’s first author, mechanical engineering graduate student Thomas Libby, also will report the results on Jan. 7 at the annual meeting of the Society for Integrative and Comparative Biology in Charleston, S.C. Full is enthusiastic about the interplay fostered at UC Berkeley between biologists and engineers in the Center for Interdisciplinary Bio-inspiration in Education and Research (CiBER) lab, within which he offers a research-based teaching lab that provides dozens of undergraduate students with an opportunity to conduct cutting-edge research in teams with graduate students. Each team experiences the benefits of how biologists and engineers approach a problem. “Learning in the context of original discovery, finding out something that no one has ever know before, really motivated me," said former UC Berkeley integrative biology undergraduate Talia Moore, now a graduate student in the Department of Organismic and Evolutionary Biology at Harvard University. "This research-based lab course... showed me how biologists and engineers can work together to benefit both fields.” "This paper shows that research-based teaching leads to better learning and simultaneously can lead to cutting-edge research," added Full, who last year briefed the U.S. House of Representative’s Science, Technology, Engineering and Mathematics (STEM) Education Caucus on this topic. "It also shows the competitive advantage of interdisciplinary approaches and how involvement of undergraduates in research can lead to innovation."

IF people want a good example of the potential hazards of genetic testing, they need look no further than a new test linked to Alzheimer's disease, say two American researchers. The test results are so ambiguous, they warn, that people could be unfairly discriminated against if prospective employers or insurance companies got hold of them. In 1993, researchers led by Alan Roses at Duke University in North Carolina found that people who carry two copies of one variant of a gene for the blood protein apolipoprotein E (ApoE), called Roses describes ApoE as "the first susceptibility gene for a common disease". Eventually, it will give people an idea of their risk of developing Alzheimer's - in the same way that doctors use cholesterol levels to predict people's risk of... To contin

- According to media researchers, adolescents frequently look to celebrity role models for guidance on fashion, attitudes and behavior. - Kids who see a lot of drugs and sex on-screen tend to drink, smoke and become sexually active sooner in life. - Consuming media in a social environment can mitigate its negative effects. Young people can gain valuable insights by watching or discussing troubling stories with friends or family. Video games, movies and television, Facebook and Twitter—for a couch-potato child, digital culture is rarely more than a fingertip away. Young Americans spend on average about seven and a half hours a day with digital media. In fact, they often multitask, using many devices simultaneously to pack in some 10 hours and 45 minutes’ worth of content every day, according to a recent Kaiser Family Foundation report. With kids devoting more free time to media than many adults spend at their full-time jobs, you would not be alone in wondering what they are taking away from the experience. Of course, hand-wringing over how TV and the Internet are warping young brains is hardly new. Even for kids bedazzled by tweets and text messages, video—whether on a smartphone, at a movie theater or on an actual TV—still dominates the digital landscape. Indeed, recent studies show that children and teenagers develop beliefs directly influenced by the movie characters and TV stars they observe.

Abstract: The Earth is already all too close from being getting all too hot, from its astronomical position at the interior edge of the Sun’s Habitable Zone. The Greeks viewed Gaia, the Earth, as the Mother Goddess from whom all other gods sprang. Yet, discoveries they made later showed that this metaphysics was misleading. In truth, habitable planets, far from being all powerful, are confined to narrow zones around their stars (and these zones move, and are under continual threat, as I describe below): Vertically the masses, going up, the unit being the mass of the sun; as stars gets bigger, they get hotter, thus they change color, covering the entire black-body spectrum, from brown dwarves to blinding ultra violet hot “Blue Stragglers”. Horizontally, the distance from the star; the graph gives only a rough idea of the notion of Habitable Zone; in truth the whole point of this essay is that Earth is at the edge of Sol’s Habitable Zone, within 1% of boiling; Habitable Zones narrow as the stars get smaller, and get much larger, far out, around bigger stars. The life of Earth on the edge has got more dicey in the last 400 million years. Thus the risk of hyper warming is greater than in the Carboniferous Era. By pumping into the atmosphere the equivalent of 100 million tons of CO2, every single day, we are, literally, playing with fire. (A first counter-measure would be to outlaw, through regulations, those gases that warm up the air a lot, and are not indispensable; for example leaks in the pipelines of the USA allow 4% of the CH4 to escape!) The two close calls by large space rocks were a reminder that this is a serious, not particularly friendly universe. Something to meditate carefully. Those who play apprentice sorcerers with the climate and planetary ecology should pay attention. For reasons having to do with the periodic table, the frequency of elements and the chemical characteristics of carbon, namely its ability to form many liaisons, it seems likely that life in the universe will have to resemble life on Earth. That is being water, carbon and oxygen based. (Believing that life does not have to be carbon-centric may sound cute, but it’s unreal.) Thus the habitable zone is the zone around a star where it is neither to hot, nor too cold, and a planet can support water. Not all stars can have an habitable zone: the greater the mass of a star, the more fiercely it burns. A star with five times the mass of the sun will typically have 625 times the luminosity of the sun. Why? In small stars, the part of the core hot and dense enough to sustain thermonuclear fusion is relatively small. In large stars, it becomes enormous, and embraces much more of the thermonuclear fuel tank. Thus, the larger the mass, the shorter the lifespan of the entire system orbiting the star. A star with 60 solar masses will shine only 3 million years before running out of hydrogen. At that point it will run hotter and hotter as it burns heavier elements until it explodes as a super nova. A star of five solar masses will live longer, but still only 100 million years or so. Long enough to make it a tourist destination, not long enough to evolve life (all the more as the habitable zone will migrate out fast, as the stellar furnace gets hotter, fast). Even a star with only 50% larger mass than the Sun will live only three billion years. On Earth, after that duration, the first oxygen making organisms were appearing, and the atmosphere was going to change completely, from reducing to oxidizing. That would bring the “Snowball Earth” episodes, 600 million years ago, or so, when most of the planet froze, before enough CO2 could be generated to reach the appropriate greenhouse effect. Clearly, for evolving advanced life, more than a billion years is needed. Thus planets with indigenous life will be restricted to red and yellow dwarves (the sun is one of the latter, with an estimated lifespan of ten billion years before turning ephemerally into a red giant). The 2012 sci-fi (silly) movie “Battleship” has it right on that point: most of the habitability is fo

A C-ration is canned food that is pre-cooked and issued to soldiers in the military when it is not possible for them to eat fresh food. In the military, the fresh food is referred to as A-rations, while B-rations are generally food that is packaged but not prepared. D and K rations are also issued to soldiers and are referred to as emergency or survival rations. The development of rations began in 1938. However, it was two years later, in 1940, when they were first field tested. After these tests, the military begin to distribute them on a regular basis. After WWII, because of budgetary concerns, the military began to standardize C-rations for field issue. The MCI (Meal Combat Individual) would replace the C-rations in 1958. Though given a new name, the MCI was not much different then C-rations. Because of that fact, many people referred to them as such. C-rations first came on the scene as a replacement for the Reserve Rations. They were originally designed to be used on an occasional basis. To make it stretch, the D-ration survival bar was used as a supplement to it. C-rations were developed as a better tasting ration then the Reserve Rations. It was also designed to be more nutritious and to keep better. The original C-rations were 16 ounces. However, they would be reduced 4 ounces to 12 ounces, after field tests were conducted in 1940. There were three versions of the meal. There was a meat and potato hash option, meat and beans and meat and vegetable stew. Soldiers were also issued a B-unit or bread and dessert can. The cans used to hold c-rations originally had an aluminized finish. This would eventually change. In 1940, the military started to use gold lacquer finish. This was primarily because to avoid or at least minimize, corrosion. Green paint was eventually used to color the cans. Each can was opened with a key, which was soldered to the bottom of it. The C-rations cans were cylindrical. Many soldiers disliked this design and requested that they be rectangular in shape and flat. This would have made the rations easier to pack. The military refused, citing the fact that the number of commercial machinery necessary to create rectangular cans was lacking. C-rations were not looked upon favorably by those in the Marines and Army during WWII. The cans were heavy and difficult to transport. Having to eat the same meals day after day was a common complaint as well. Because so many suppliers were creating the meals, there was very little consistency. C-rations were meant to be eaten occasionally. Because of that fact, monotony was never supposed to be an issue. However, soldiers ended up eating them for weeks at a time.

We begin with the Big Bang, the origin of time and space, when all matter and energy were created. It occurred approximately 15 billion years ago when a point with unimaginable temperature, pressure and density exploded. Within about a minute of the Big Bang the universe had expanded by a million times, and it is still expanding today. After 2 billion years matter started to clump together to form the first galaxies and stars. After a further 8 billion years, the sun and planets of our solar system came into being. In this session we'll cover the formation of the solar system, asteroids, meteorites, comets and why the Earth is particularly special in this system. 1. Time: 0 Matter and energy are created in the Big Bang. 2. Time: 60 secs Temperature: 1 billion °C. Protons and neutrons join together to make nuclei, the central cores of atoms. 3. Time: 300,000 years Electrons combine with nuclei to produce atoms of hydrogen and helium. 4. Time: 1 billion years Matter clumps together to form galaxies, where stars form. 5. Time: 10 billion years The sun and planets form. Located two-thirds of the way out of the centre of the Milky Way galaxy, the sun is sometimes described as an undistinguished star in an undistinguished neighbourhood. It is surrounded by a family of planets and their satellites, plus asteroids and comets. Matter drifts through space as clouds of gas and dust; the first stage in the formation of the solar system was the collapse of one of these interstellar clouds. This created a 'protoplanetary disk'--the solar nebula. Astronomers have suggested that the cloud collapse was triggered by a shockwave from a nearby supernova (the sudden, rapid explosion of a star). Dustgrains, falling towards the centre of the nebula clumped together, eventually formed planets, their growth controlled by factors such as the nature of the grains and the degree of turbulence within the nebula. The collapse of the cloud and subsequent accretion of material took place over a short time interval of 1 to 3 million years. Asteroid 433 Eros, photographed from an altitude of 200 kilometres in February 2000. It is a stony asteroid, 33 km long by 13 km wide. © NASA/JPL/Caltech. The Asteroid Belt, a swarm of several thousand small rocky planets (planetesimals), marks the boundary between the rocky planets (Mercury, Venus, Earth and Mars) and the outer gas giants (Jupiter, Saturn, Uranus and Neptune). Asteroids are the leftovers from the planet-building process. Although the largest, Ceres, is around 1000km across, the majority measure only several kilometres across. They are grouped into types based on composition: some are predominantly composed of iron or stone whilst others are rich in carbon. Their cratered surfaces are evidence of collisions with other asteroids, often outside their stable orbits around the sun. Fragments ejected from the Asteroid Belt may fall onto the inner planets--on Earth, these are known as meteorites. Almost all meteorites (pieces of rock and metal that fall to Earth) are fragments from asteroids. The study of meteorites permits a more complete understanding of the materials--the organic dust--that formed the Earth, and how they changed through time. There are two main types: melted and unmelted meteorites (chondrites). Melted meteorites: Melted meteorites come from asteroids that were so hot they melted. They are slightly younger than the chondrites and comprised of iron, stone or a combination of both. The study of melted meteorites can help explain the processes involved in the formation of planets and planet cores. A polished piece of pallasite (stony-iron meteorite), about eight cm across. Chondrites: Chondrites are the most primitive meteorites. They are made from the same dust that made the Earth but the composition of their parent asteroids has changed only slightly since their formation early in the history of the solar system. They are therefore direct ancestors of the Earth and are studied to gain a better understanding of how the Earth has evolved to its present state. Chondrites are stone meteorites and contain calcium and aluminium-rich inclusions (CAIs), which are the oldest of all planetary materials, formed very soon after the initial collapse of the solar nebula. They also contain chondrules, tiny, millimetre-sized spherical formations, which along with the CAIs provide information about the Earth's formation. The presence of carbon (mainly in organic compounds) in some meteorites is direct evidence that asteroidal material might have contributed the ingredients for life on Earth during bombardment.

Nature & Science At Fort Union the transformation from a frontier to an agricultural environment led to the reduction and extirpation of native plant species, followed by the introduction or invasion of exotics. The most notable exotics at Fort Union are crested wheat grass and smooth brome, Canada thistle and Leafy spurge. GRASSES-Dominant native grass species include green needle grass, blue grama, western wheat grass, side oats grama and needle and thread grass. Trees-Cottonwood trees dominate the riparian area, ash and dogwood trees also are found. SHRUBS-Willow species, Choke cherry, and buffalo berry are the predominant shrubs. Did You Know? In 1832 George Catlin, concerned about the destruction of Indian civilization, wildlife and wilderness, wrote they might be preserved "by some great protecting policy of government..in a magnificent park.. a nation's park...." which became the national park idea.

DIOCESE OF CHRISTCHURCH (CHRISTOPOLITANA) (Its centre being Christchurch, the Capital of Canterbury, New Zealand.) It comprises the provinces of Canterbury and Westland, a small portion of the Province of Nelson, and the Chatham Islands. In July, 1840, the French corvette l'Aube started for Akaroa (Canterbury) to land a body of settlers there, and to annex to France the South Island of New Zealand. The former project was accomplished; the latter was frustrated by lieutenant-governor Hobson. Having ascertained the destination and purpose of the expedition, he raced the corvette to Akaroa in the warship Britomart and, four days before the arrival of the French settler, proclaimed the south Island British territory. The first English colonists (the "Canterbury Pilgrims") landed at Lyttelton 16 December, 1850. They, and many that followed them, were sent out by the Canterbury Association, a High Church organization whose colonizing scheme was described by Low churchmen as a "Puseyite invasion of New Zealand". The Canterbury concessions (nearly 3,000,000 fertile acres) were intended to be and remain a great Anglican monopoly. This, however, was prevented by the Constitution Act of 1852. In all Canterbury, including Akaroa, there were 136 Catholics in 1851. During the first two decades they were ministered to by the Marist Fathers Comte, Pesant, Tripe, Séon, Petitjean, and others. In 1860 Christchurch received its first resident priest, Father Chataignier, S.M. On 11 September of that year he laid the foundations of the first church in Canterbury, a wooden structure, 28 by 18 ft. A more spacious church was erected in 1864. Enlarged and beautified by Father Ginary, S. M., this subsequently served as a pro-cathedral from 1887 till 1905. On the discovery of gold in 1864 there was a great influx of people to Westland, which led to the formation of missions in Hokitika, Greymouth, and elsewhere on the West coast. The Diocese of Christchurch, formerly part of the Diocese of Wellington, was established by papal Brief, 10 May, 1887. On his arrival in Christchurch there were in the diocese 35 churches, 16 schools, 7 convents, and 17 priests (8 secular and 9 Marists). The history of the diocese since then is one of closer organization and steady progress. The Marist Brothers and the Sisters of Nazareth were introduced; new parochial districts formed; 30 churches built or enlarged; 15 presbyteries, 9 schools, 10 convents, and 3 monasteries (Marist Brothers) erected; and a white stone cathedral, one of the most beautiful religious edifices in Australasia, was opened 12 February, 1905. Parochial districts, 21; priests 38 (20 Marists, 18 seculars); Marist Brothers, 13; nuns, 150; convents, 17; Marist Brothers' monasteries, 3; boarding schools (girls), 6; primary schools, 30; charitable institutions, 2 (Nazareth Home and a great Magdalen Asylum); Catholic population, about 25,000.

Build a solid foundation in science, formulation and product development—find out more! Most Popular in: US Researchers Question Possible Moisturizer-Tumor Link Posted: August 15, 2008 A US study of has reported that some moisturizers may promote skin cancer. Biochemist, cancer researcher and pharmacologist Allan Conney and his research team at Rutgers University reported in the Journal of Investigative Dermatology that some ingredients in moisturizers may increase the rate of getting cancer after sun exposure. The researchers planned to test topical caffeine's inhibition of the development of skin cancer, but stumbled across their finding during their control. As a result, the team was surprised at their results before they had even added the caffeine to the cream. The mice were exposed to ultraviolet light for 20 weeks, putting them at high risk for skin cancer. Four moisturizers then were applied to hairless mice five times a week for 17 weeks. The researchers found that the moisturizers increased the rate of tumor formation and the number of tumors in the mice. The radiation damaged the skin of the mice before the moisturizing creams were applied, which might account for the moisturizers' unusual tumor-promoting effect. To test what ingredients might be speeding the rate of tumor formation, the researchers had one of the moisturizers formulated without mineral oil and sodium lauryl sulfate. The resulting formulation did not increase the rate or number of tumors; however, not all of the four moisturizers were formulated with these two ingredients. The scientists concede that the skin of humans differs form the skin in mice. Some scientists and biologists argue that the creams should have been applied for a longer duration to produce conclusive results.

Principles of Aircraft Engine Lubrication By Harold Tucker July / August 1998 At this year's Professional Aviation Maintenance Association's annual meeting which took place in Kansas City, Harold Tucker, Lubricants Technical Director for Phillips 66 Company offered a presentation to maintenance personnel from around the country on some of the basics of aviation engine oil. The following is an overview of that presentation: What major functions do lubricants perform in aviation engines? Lubricants are used to reduce friction and wear, whether it's in an aviation engine or the wheel bearing on a car. Other major functions of a lubricant include cleaning, cooling and sealing, in addition to helping fight corrosion and rust in the engine. Airplanes that are used infrequently especially need the corrosion and rust protection that good aviation lubricants can provide. Unused aircraft have a high potential for rust and corrosion, among other downtime problems. The more frequently and consistently an airplane is flown, the easier it is to properly maintain and lubricate. What are the benefits of using a lubricant that cleans the engine? All aviation oils clean. When we say an aviation oil cleans, we think of removing sludge, varnishes, and grunge accumulations in the oil pan, on plugs, or in the screen. However, when a lubricant keeps your airplane engine clean, it also means a clean ring belt area and better control of the combustion process. When those rings are able to move freely, your engine operates at higher efficiencies, has better ring seal, produces less blow-by, and consumes less oil. A dirty ring belt restrains the movement of the rings within the grooves and they can't seal. This may create pressure between the ring face and the cylinder wall — leading to wear, scarring or scuffing. How do aviation lubricants keep an engine cool? Air-cooled aircraft engines rely on their oil for cooling far more than water-cooled automotive engines. Automotive oil typically accounts for about 40 percent of the engine's cooling capacity. In aviation engines, the oil must carry off a greater percentage of the engine's heat. Oil is a heat-transfer medium which flows through the crankcase and oil coolers, and dissipates the heat from moving parts, thus constantly cooling engine bearings and piston rings. Without the cooling oil film on a cylinder wall, the rings wouldn't have a good heat transfer path. This can lead to melting, galling, or scarring problems. Oil also cools the valve springs and the whole valve train. How does oil seal an aviation engine? Aviation oil not only provides a seal between the rings and cylinder walls, but also helps seal the gasketed areas and the rubber or synthetic seals for the crankshaft. When oil washes around those areas, it helps retain a seal. Thus, aviation oil must be of a blend or formulation that is compatible with the seal materials so that the seal itself lasts longer. What about the job we think of first when we think of oil — lubrication? Lubricating properties are among the most important physical characteristics of aviation oil. Proper lubrication requires a strong enough and thick enough oil film between moving parts to keep friction and wear to a minimum. Oil properties can include boundary or mixed film, dynamic, hydrodynamic, and elastohydrodynamic forms. Boundary or mixed film lubrication is found in the upper cylinder area in the outer boundary of an aircraft engine. This is the most remote engine area to lubricate because the oil rings scrape most of the oil film off the cylinder walls before it reaches the upper cylinder. However, there must be a residual amount of lubrication in the upper cylinder to protect the engine on startup. Also, if an engine has been sitting idle for a month, some lifters have been pressed against cam faces and loaded under maximum spring pressure. Most of the oil has been squeezed out of that junction. When the engine is fired up, it takes a while to get oil to all those surfaces again. So, for that crucial moment, you need good boundary or mixed film strength at those critical boundary areas. Oil film retention is not as critical on startup in cam and crank journal areas.

June 27-July 2 Democratic National Convention, Chicago, Illinois Roosevelt flies to Chicago from Albany to deliver acceptance speech in person (the first time this is done) in which he declares, "I pledge you, I pledge myself, a new deal for the American people." FDR and the Democrats win the election by a landslide. Democrats take control of both houses of Congress. FDR inaugurated the 32nd president of the U.S. "The only thing we have to fear is fear itself." FDR issues a proclamation declaring a four-day "bank holiday" throughout the nation effective March 6. All banking transactions stop and embargo on exportation of gold, silver, and currency. Summons Congress to special session for March 9. March 9-June 16 "Hundred Days" session FDR gets a willing Congress to enact many of the New Deal programs. This first day Congress passes the Emergency Banking Act, giving FDR broad powers over banks and foreign exchange. Bank holiday ends March 10--banks can reopen when they prove that they are solvent. Within three days, 1000 banks will reopen and national confidence picks up. FDR gives first "fireside chat". Congress passes the Reforestation Relief Act, establishing the Civilian Conservation Corps (CCC); it provides work immediately for 250,000 young men (18-25) in reforestation, road construction and developing national parks. Work camps begin to spring up. By the time it eases in 1941, two million people have worked on its projects. FDR takes the nation off of the gold standard. Congress passes the Federal Emergency Relief Act, which authorizes immediate grants to states for relief projects. Unemployment has reached 14 million-over one quarter of the nation's work force. Roosevelt signs the Agricultural Adjustment Act to provide immediate relief to farmers by setting prices for agricultural products and paying subsidies to farmers for curtailing production of certain crops that were in surplus. Congress establishes the Tennessee Valley Authority (TVA) to construct dams and power plants along the Tennessee Valley; electricity will go to residents, many of whom lacked it previously, and fertilizer will be sold. Congress passes the Federal Securities Act to monitor and regulate stocks and bonds. Congress passes the National Employment System Act. Congress passes the Home Owners Refinancing Act to provide mortgage money and other aid to homeowners. It will go out of business in June 1936 after providing loans for some one million mortgages. The final day of the "Hundred Days" session.

It is a mostly sedentary bird, found in a catholic variety of open habitats. Within range, its penetrating and rhythmic, three-syllabled crooning is a familiar sound at any time of the year. Its name is derived from the semi-collar of black feathers on the lower nape, a feature shared with a number of Streptopelia species. Like all doves they depend on surface water. They congregate in large flocks at waterholes in dry regions to drink and bathe. Their body feathers are darkest on the upper side, where they are coloured in dull tones of grey and brown, with shades of lavender on the nape. It is paler below, where a tint of pinkish lavender is usually present. The lower belly and crissum is white. As with related species, they have white fringes and conspicuous white tips to the otherwise slate grey tail feathers. The tail pattern is particularly noticeable during the display flight. Individual plumage variation is high, with some light and others almost sooty. Males and females look alike, although the males are slightly bigger. They measure 25–26.5 cm (9.8–10.4 in) in length and weigh 92–188 g (3.2–6.6 oz). The eyes are almost black, the bill is black and the feet are dark purple. It occupies a diverse range of habitat types, including semi-desert scrub, Boscia and Acacia savannah, a variety of woodland types, farmlands, open

Campaigners on Saturday welcomed a World Health Organization pledge to tackle research and funding gaps concerning some of the developing world’s biggest killer diseases. Member countries are expected to hold talks later this year on an expert group’s recommendations that a globally binding convention is needed to address neglected tropical diseases (NTD), tuberculosis and others currently overlooked by the research industry. It follows a meeting of the WHO’s decision-making body, the World Health Assembly, in Geneva where members adopted a resolution calling on director general Margaret Chan to set up the meeting. The document, the result of three-day negotiations, meanwhile urges governments and the private sector to boost investment in health research for diseases which disproportionately affect the developing world. “These were extremely tough negotiations with the US, the EU — led by France — and Japan making every effort to block progress on what health experts agree should be the way forward to meet the medical needs of people in developing countries,” said Michelle Childs from Medecins Sans Frontieres. “While there’s no doubt we are disappointed that there was not an immediate decision to move towards a research and development convention, countries have agreed to a formal process for considering the report’s recommendations and will bring these discussions back to the WHO in January,” said the policy director for medical charity’s access campaign. The WHO-appointed group said in a report published last month that public investment in health research was currently dominated by wealthy countries and their own needs. The panel recommended a “global binding instrument” to help developing countries access the drugs and technologies they require and suggested member states commit 0.01 percent of their GDP to fund the work. In a draft resolution submitted to the WHA, Kenya urged the immediate set-up of a negotiating body to develop a convention based on the group’s recommendations. This was countered by a document from the US, Japan and others supporting more informal consultations. After about 15 hours of talks the agreed resolution requested WHO chief Margaret Chan “hold an open-ended member states meeting in order to analyse the report and the feasibility of the recommendations.” The Drugs for Neglected Diseases initiative (DNDi) said it hopes that national and regional-level talks also requested in the resolution will pave the way for a global response.

In southwest Taiwan, the rocks contain both methane and carbon dioxide. Many mud volcanoes spurt out gas. If methane is released it can spontaneously combust on reaching the surface, which is the mechanism behind the famous “fire water grotto” in Guanzihling (關仔嶺). Carbon dioxide is also released, albeit in a less spectacular fashion. Thankfully, there have been no reports of either causing a catastrophe. Naturally, CCS requires government regulation and supervision. Industry cannot be left to do as it pleases. In the US and Canada seven regional carbon storage associations exist, involving business, industry and academia. In the UK, the EU and Australia there are organizations specifically established for this purpose. These advanced countries are all trying to capture this greenhouse gas and store it un

- Apr 27, 2010 3:33 PM EST - [num] Comments If you read only one story about purple pokeberries all day, let this be the one. Pokeberries -- weeds that children smash to stain their cheeks purplish-red, and that Civil War soldiers used to write letters home -- could be the key to advancing solar power. Researchers at Wake Forest University in Winston-Salem, North Carolina, have use a red dye made from pokeberries to coat their efficient and inexpensive fiber-based solar cells. The dye acts as an absorber, helping the cell's tiny fibers trap more sunlight to convert into power. The beauty of using pokeberries is that they grow hardy even during droughts and in rocky, infertile soil. That means residents of rural Africa, the university says, could raise the plants for pennies. Then they could make the dye absorber for the extremely efficient fiber cells and provide energy where power lines don't run, says David Carroll, Ph.D., director of Wake Forest's Center for Nanotechnology and Molecular Materials. "They're weeds," Carroll said. "They grow on every continent but Antarctica." Wake Forest holds the first patent for fiber-based solar cells, granted by the European Patent Office in November. A spinoff company called FiberCell Inc. has received the license to develop manufacturing methods for the new solar cell. The fiber cells can produce as much as twice the power as current flat-cell technology.

Holy Qurbana – 4 THE ANAPHORA OF THE FAITHFUL The word ‘Ana’ means ‘Up’ and ‘Phora’ means ‘to carry’. The Anaphora is the solemn prayer of thanksgiving which our Lord uttered at the Last Supper and the works and actions which He used when he instituted the Eucharist. The original Anaphora of the rite of Antioch is that of St. James, but there are a great many others, eighty-eight in all, which were introduced in later times. Of these about sixty-four have their authors identified, which may be used for celebration. The Kiss of Peace The kiss of peace is of apostolic origin (Rom 16:16, 1 Cor. 16:20) and is used in every liturgy to signify the ‘fellowship of the Spirit’ of which the Eucharist is the outward sign. It shows the love and harmony which should exist among the followers (disciples) of Christ. By this we fulfill the word of the Lord which says, “If thou offer thine offering and remembers that thy brother hath aught against thee; leave thine offering, and go, be reconciled with thy brother” (Mathew 5:23)

Originally posted by WeRpeons reply to post by waynos So explain this to me without being so denigrating. I simply pointed out your lack of understanding of this topic and was not denigrating in any way. Pardon me for not writing a fuller explanation in that post, but I've written it out so often for it simply to be ignored as inconvenient that I now wait to be asked. I understand how atmospheric conditions can change how contrails expand. I am relating what I have never observed in all my years growing up and playing outside as a young boy all day from morning until the street lights came on. You can't tell me that the kind of contrail grids people are seeing today existed back in the 60's and 70's. Sure, I've observed contrails crossing each other in the past, but nowhere near the amount nor the expansive appearance I've seen today. This would be correct. As you say, you saw contrails crossing in the past. This was the beginning of what we have today. If you go back to the 1970's, for instance, quite apart from there being fewer aircraft than there are now, the nature of the worlds air fleets was also very different. I will assume you know the engine terms I am going to use here, if not you can look them up or ask. High Bypass tubofans, the sort that, under the right conditions, leave long thick trails behind high flying aircraft, at that time powered ONLY the very largest, widebody jets. These were the Boeing 747, McDonnell Douglas DC-10, Lockheed TriStar and Airbus A300B. These aircraft were new then, the 747 was the first of them, entering service in 1970, DC-10 and TriStar followed in 1972 and the A300B in 1974. They would not be widely seen in service until about 1977-79 Most airlines still operated older types such as the 707 and DC-8 on their long range routes, these were powered by turbojets or non high-pypass turbofans of an older generation and even though they did create contrails (possibly the ones you observed) they were less visible than now, and of course far fewer. But that is only part of it. The far more populous fleets were made up of short range aircraft. These included the early model 737, DC-9, BAC One Eleven and Sud Caravelle, for example. These were powered by turbojets and flew shorter routes at lower altitudes, then below those there were the regional airliners, Vickers Viscount, Lockheed Electra, Convair 340 etc down to the smaller 30+ seaters like the DC-3 (still in wide use at the time) HS.748, Fokker F.27 etc which were all propeller driven and flew even lower, mostly not leaving any sort of trails at all. Fast forward to the 1990s and ALL these propeller and turbojet driven airliners are gone, there are some modern turboprops such as the Dash 8 and ATR series still doing well, but basically every single size of airliner from 50 seats up to 850 is served by an aeroplane powered by high bypass turbofan engines and flies at higher altitude in the more rarefied air, because this is what costs least and generates most profit. The result is masses of trails all over where there were previously very few. But they WERE there. The vapor trails today expand at a much quicker rate and their is definitely a concentrated effort and planned spacing between the trails. This is an assumption, The reason the trails expand so much more is because they contain so much more water, due to the nature of the high bypass engine which compresses the ambient air without it going through the engine core and burning in order to augment thrust without using more fuel. While burning fuel itself creates water, the sudden depressurisation of this bypass air aft of the engine simply adds to that (think of the effect when you pull ring-pull on a can of pop and the mist that is created, but multiplied and sustained. An aeroplane would not be able to replicate this effect by carrying something it sprayed, there would be too much volume required. Indeed, it could be said that without the invention of HBPR engines the trails now would be even more vast as so many more engines would be required and they would burn so much more fuel to power the size of aircraft that now By way of an example, the Saro Princess was powered by TEN Proteus engines and did not sell, only one ever flew. A projected airliner by the same firm called the P.192 which was slightly larger than the Airbus A380 would have required 24 RR Conways (4 of the same engine powered the 707) todays A380 manages with 4 R-R

Students are not receiving the practical science education necessary to produce the next generation of scientists, warns Commons Science and Technology Committee. The Commons Science and Technology Select Committee today publishes its report on practical experiments in school science lessons and science field trips. It concludes that many students are receiving poor practical science experiences during their secondary school education. Andrew Miller MP, Chair of the Committee, said, "We heard evidence that the pressures of managing a busy curriculum, challenges in finding time for specialist continuing professional development, or time to get out of the classroom, are all factors contributing to a decline in the quality of practical science. This is worrying. If the UK is to be confident of producing the next generation of scientists, then schools -encouraged by the government - must overcome the perceived and real barriers to providing high quality practicals, fieldwork and fieldtrips." The report says health and safety concerns may be used as a convenient excuse for avoiding practicals and work outside the classroom, but the MPs found no credible evidence to support this frequently cited explanation for a decline in practicals and trips. Knowledge and practical skills Instead, the committee says more focus is needed on what happens after teachers have been recruited to the profession: knowledge and practical skills must be maintained and developed in order for high quality science education to be delivered. High quality science facilities and qualified and experienced technical support are vital. A career structure for technical staff should be provided and the government should ensure schools provide science facilities to match its aspirations for science education. Practical science is relatively expensive and carries little cachet for parents comparing schools. The inspection regime and the requirements set for ex

- Posted By: Jaime Adler - Written by: Greg Giusti, UCCE Forest Advisor Understanding the Role of History on California’s Oak Forests In his book The Destruction of California, Ray Dassmann (1965) chronicled the dramatic impact land-use practices have had on wildlife populations throughout California during the past 150 years. He articulates the impacts from the loss of wetlands, forest conversion and urban expansion on a number of economically important wildlife species. In his book, he quotes an early California pioneer, A. B. Clark (1852) who recorded the abundance of vertebrate diversity that was so apparent in the early days of exploration. Mr. Clark wrote, “ I have no where seen game as plenty as in the (central) valley. We killed an antelope in the morning. We could frequently see herds of deer and elk in different directions around us, as well as wild horses”. Today, concentrations of deer, elk and waterfowl populations can be found in remnant habitats distributed in small, isolated patches throughout the valley. More recently, Walter (1998) provides a complete overview of how past land-use practices have changed the landscape of California so dramatically that in some cases counties “have lost their natural heritage” and are mere remnants of their past biological richness. Brown et. al. (1994) and Marchetti and Moyle (1995) have outlined the once abundant numbers of salmon and how historical land-use practices directly impacted anadromous fisheries and how the legacy of these practices continues to impact these species. They specifically identify water diversions and related watershed degradation caused by past and on-going human activities as the direct cause of these declines. Moyle et. al. (1994) has identified as many as 10 anadromous species (including salmon, steelhead trout, lamprey, sturgeon, smelt) that meet the scientific criteria necessary for special protective status. The common thread binding the terrestrial and aquatic inhabitants of pre-settlement California is the fact that many of these species were found in areas that we commonly referred to as oak (Quercus) woodlands. In many cases, the abundance that has been chronicled illustrates the importance of oak habitats to many of the species which spent a significant portion of their life history living in, or migrating through, oak woodlands. Because of their ubiquitous distribution oaks have been impacted throughout California during the past century. An early account written by Willis Linn Jepson (1909) states; “In some regions where the horticultural development has been rapid or the needs of an increasing population urgent, extensive areas have been cleared to make room for orchards or gardens, and scarcely a [valley oak] tree remains to tell the story of the old time monarchs of the soil, in other regions the destruction has not been so complete” (Pavlik et. al. 1991). Modern day land-use impacts on oak woodlands continue through urbanization and the conversion of oak woodlands to intensive agriculture. California’s History of Forest Policy toward Oaks In 1885, the Governor of California approved an act that authorized the appointment of a three-man State Board of Forestry, the first such body in the nation. Because of a lack of clear statutory authority and minimal budgeting, the original Board was only able to act in an educational and advisory capacity. By 1905, the Board of Forestry was supplemented by creation of the post of State Forester and in 1927 the Division of Forestry was organized. In 1947, the original Forest Practice Act was passed by the State Legislature. Although the responsibilities and powers of the Board under the old act were less than they are today, the 1947 Act laid important foundations of experience and procedure which led to further development for the Board. Throughout the period of the 1950s and 1960s, the Board of Forestry functioned under the mandate of the 1947 Act by formulating forest policy for the state. When the Division of Forestry was elevated to departmental status in 1977, the organizational relationship between the Department and the Board was retained. This reorganization of the Department had no effect upon the Board's mandated duties and responsibilities. With the passage of the Z'berg-Nejedly Forestry Practice Act of 1973, the Legislature reorganized the Board and concomitantly expanded its powers and responsibilities. To achieve a balanced approach to forest land policy, the Public Resources Code delineates the character of the Board by designating that five members will be from the general public, three are chosen from the forest products industry, and one member is from the range-livestock industry. The Board is recognized as having the legislative authority to regulate both privately owned conifer and oak woodland forest types. Historically, the Board has focused its regulatory authority on those lands capable of producing commercial lumber products choosing to support an educationally based program for

Treating type 1 diabetes (T1D) with gamma-aminobutiric acid (GABA) attenuates insulitis, preserves islet β-cell mass, and can even lead to β-cell regeneration and reverse established disease
Treating type 1 diabetes (T1D) with gamma-aminobutiric acid (GABA) attenuates insulitis, preserves islet β-cell mass, and can even lead to β-cell regeneration and reverse established disease in experimental mice, researchers claim. Studies by a team at St. Michael’s Hospital in Toronto in different mouse models of type 1 diabetes, have found that GABA promotes β-cell growth and survival, and exerts immunoinhibitory effects that may protect them against autoimmune destruction. Writing in PNAS, Qinghua Wang, M.D., Gerald J. Prud’homme, M.D., and colleagues conclude that because GABA does not cross the blood brain barrier and can be administered orally in humans in large amounts, GABA or GABA-mimicking drugs may have therapeutic utility in the prevention and treatment of T1D. The researchers report their findings in a paper titled “GABA exerts protective and regenerative effects on islet beta cells and reverses diabetes.” T1D is an autoimmune disease characterized by insulitis and islet β-cell loss, but there are currently no effective therapies capable of restoring β-cells from the surviving islet cell population, or suppressing the autoimmune response, the St. Michael’s team reports. GABA is a major neurotransmitter in the CNS, and is also produced by pancreatic β-cells, where it acts on the GABAA receptor in alpha cells to suppress glucagon secretion. However, studies by both the St. Michael’s team and independent researchers have shown that β-cells also express GABAA receptors, forming an autocrine GABA signalling pathway, the functions of which are unknown. In view of the critical role of GABA–GABAA receptor signaling in neuronal cell proliferation and maturation, the authors hypothesized that activation of GABA–GAB

By providing information on the risks involved with transferring multiple embryos after in vitro fertilization risks that include higher chances of multiple pregnancies and complications doctors hope more couples would opt to do single-embryo transfers instead, a new study suggests. In vitro fertilization, doctors take eggs out of the woman to be fertilized with a man's sperm. Then, in what are called cycles, doctors transfer one or more embryos back into the woman. The more embryos transferred, the higher the chance of getting pregnant and having multiple babies. By only transferring one embryo, the risk for having multiples decreases, but it may take several cycles and more money to become pregnant. In a Dutch study of 308 couples undergoing in vitro fertilization, 43 percent of couples who were informed of the risks chose to go the single-embryo route for their first cycle of embryo transfer, compared to 32 percent of couples who didn't receive special information and had standard care. In the second cycle of embryo transfer, the percentage was even lower 26 percent of couples who had the special information opted for single-embryo transfer, compared to 16 percent who had the standard care, according to the study. But while the couples who were informed had a higher rate of choosing singe-embryo transfer, the percent difference is not statistically significant, the study said, and could possibly be from pure chance. There were no differences between the couples' levels of anxiety or depression compared with those receiving standard care, but couples who chose single-embryo transfer saved some money on average, $219.12 per couple.

The world of IT security is full of partial truths and paranoia – some of which is completely justified. Sometimes, steps are taken that actually are beneficial, but without knowing the reason behind the precautions, many administrators are lulled into a false sense of security. Here are some common misconceptions that I see in action frequently: Security Myth #1: If I set my password strong enough, my system will be secure. The Facts: There are many ways to compromise a system. For example: exploitable code on your website, lax filesystem permissions, and publicly accessible services running on your system (such as email or chat). In fact, having a long secure password is often like having a steel security door with retinal scan technology on a grass hut. Don’t get me wrong, having strong passwords is a great thing, but don’t forget to look at the rest of your system! The Side Effects: - Longer passwords take longer to type (obviously). - You are more likely to forget a longer password. - You are more likely to mistype a longer password (and get locked out). - If you force this policy on your end users they are more likely to write the password down (bad). Security Myth #2: If I replace letters with their corresponding l33t speak numbers (e.g. hello -> h3110), it will make my password more secure. The Facts: Technically, yes it will make your password more secure, but only marginally. Simple character substitution is a common feature among brute force tools. This will slow down the brute force attack, but your system may still eventually be compromised by a hybrid dictionary attack. You might also consider configuring the brute force protection options on your server. The Side Effects: There are no side effects – in fact, this is a far greater idea than simply using a dictionary word. However, it is best to also add some additional numbers or letters to throw off brute force tools. Many brute forcers also allow for pre-pending or post-pending a string of numbers (e.g. 123hello or hello123). It is better to place random numbers or characters in the middle of your password so that it is not vulnerable to a dictionary attack (e.g. hagen!23daas). Another alternative to a secure and easy to remember password is make an acronym of a famous phrase or quote. For example: “sticks and stones may break my bones” -> “S&smbMb!$”. Security Myth #3: If I change the port number for RDP/SSH/Plesk or turn off ping response, my server will be safe. The Facts: This is the myth of “security through obscurity.” Changing your port number or turning off ping will only reduce attacks from computer worms and extremely lazy hackers. Say for example that you run a website on your server. Anyone who knows the URL of the website can easily find your IP address (by ping or nslookup). Then all they have to do is port scan that IP address (using a port scanning tool such as nmap or SuperScan) to see which ports are open. If your passwords are secure enough, you needn’t worry too much about the brute force attacks from the internet. You should only consider this a secondary safeguard just in case the server happens to have a vulnerable service running on it. Your first priority is making sure your system is properly patched and updated. The Side Effects: - It is very difficult to track or troubleshoot packet loss on servers that have ICMP blocked. - Changing ports may confuse your users. - You will need to remember to include this port information in any technical support request. - Many automated systems or scripts will require custom configuration.

DARPA invests in giant space nets to catch trash Garbage threatens future space elevator plans By Nancy Gohring | Published: 10:00, 16 August 2010 Forget reality for a minute and try to picture an elegant solution to the problem of space garbage. Imagine that each piece of trash floats in space like a butterfly that can be gently scooped up with a net, preventing collisions. Turns out, that's pretty close to reality. It's the concept behind the Electrodynamic Debris Eliminator, or EDDE, a space vehicle being developed by Star Inc with funding from the US Defense Advanced Research Project Agency. Jerome Pearson, president of Star Inc, presented the idea for what he calls "a space garbage truck" on Friday at the annual Space Elevator conference. Pearson was an early proponent of the idea of building a space elevator, and a paper he wrote about it in 1975 inspired the description of a space elevator in Arthur C Clarke's science fiction book, The Fountains of Paradise, which popularised the idea. Space garbage happens to be one of the biggest obstacles to building a space elevator. Pearson's proposed EDDE vehicle will come equipped with around 200 nets, like butterfly nets, that it extends to scoop up garbage in low-earth orbit. Over a period of seven years, 12 EDDE vehicles could capture all 2,465 identified objects over 2 kilograms floating in LEO, Pearson says. Related Articles on Techworld Once it captures the object, the EDDE can do several things with it. EDDE can fling the garbage such that it lands in the South Pacific, where it has little chance of dangerously landing on anything important. Or, the EDDE can deliver the object closer to Earth where it will orbit out of harm's way and eventually decay. Better yet, it can be reused in space to build a variety of useful structures, Pearson said. "So you'd be mining aluminium in orbit mainly," he said. Four EDDEs could collect enough metal and other material to build a structure the size of the Smithsonian Air and Space Museum, which could be used to host crews or store equipment, he said. Pearson acknowledges a number of challenges to the idea behind EDDE. For instance, with 12 or more EDDEs zipping around, "we may need space traffic control," he said. Just like the US Federal Aviation Administration regulates US airspace, that agency has already begun looking at ways it might monitor space, requiring vehicles like EDDEs to file flight plans, he said. Another possibly significant issue is that while Pearson is proposing the use of EDDEs to clean up garbage, they could potentially be used for more sinister purposes, and that has already raised alarms in China. For instance, an EDDE could be used for military purposes to remove a satellite from orbit. Because of those concerns, Space Inc is working on shifting the project to NASA rather than DARPA, which is part of the US Department of Defence, Pearson said. He envisions a time when EDDEs could operate under the United Nations, which could tax anyone or any country that launches objects into LEO in order to cover the clean-up of trash there. Star Inc has already been doing some testing and expects to do a test flight in 2013. If all goes according to plan, a full phase removal of trash could begin by 2017, he said. About 30 people are attending the Space Elevator conference on Friday, including Yuri Artsutanov, a Russian engineer born in 1929 who published a paper first describing a space elevator in 1960 that went unnoticed outside of Russia. A space elevator would be a long rope made of nanomaterials, stretching from Earth to a counterweight at geosynchronous altitude, about 22,000 miles (35,406 kilometers) above Earth's surface. Shuttles, like elevator cars, would travel up and down the cable, ferrying people and objects into space. Two years ago, a speaker at the conference caused a stir when he pointed to the major problem of space garbage, noting that at some point every piece of debris and every satellite would crash into the elevator. "Every one, with no exception," said Ivan Bekey, a former NASA scientist currently with Bekey Designs, at the time.
Erasing the Stigma According to the National Institute of Mental Health, early-onset Bipolar Disorder affects up to three percent of adolescents. That represents approximately one million teenagers in the United States and does not even take into account younger children.
Erasing the Stigma According to the National Institute of Mental Health, early-onset Bipolar Disorder affects up to three percent of adolescents. That represents approximately one million teenagers in the United States and does not even take into account younger children. Some families have chosen to establish their own organizations to help spread awareness and understanding in honor of a child they lost to Bipolar Disorder. Todd and Michelle Brown recently launched an interactive website at BipolarAware.org in honor of their daughter Carol Anne who suffered from Bipolar Disorder and who passed away at the age of 19. It is efforts like the Brown’s that make great progress in erasing the stigma of Bipolar Disorder.

Traumatic brain injury is associated with a profound suppression of the patient's ability to fight infection. At the same time the patient also often suffers hyper-inflammation, due to the brain releasing glucocorticoids in response to the injury. New research published in BioMed Central's open access journal Critical Care shows that including probiotics with nutrients, supplied via the patient's feeding tube, increased interferon levels, reduced the number of infections, and even reduced the amount of time patients spent in intensive care. In a small scale trial, based at North Sichuan Medical College and Hospital in China, 52 patients who had suffered traumatic brain injuries, and who were being treated in the intensive care unit (ICU), were either treated as usual or had their nutrition supplemented with probiotics. Suppression of the immune system can be measured by an alteration of helper T-cells (Th) from Th1, which stimulate the action of macrophages to fight infection, to Th2. Th2 cells recruit B-cells which in turn are involved in antibody production. This switch from Th1 to Th2 leaves patients vulnerable to infections including ventilator-associated pneumonia and sepsis. Researchers involved in this trial monitored the TH1/Th2 switch by measuring levels of the Th1-associated signaling molecules (cytokines) IL-12 and interferon gamma (IFNy). No differences were found between the groups of patients when they began the trial, and throughout the study all the patients had lower levels of IL-12 and IFN? than uninjured healthy controls. However by day 15 the patients who received the probiotics had significantly higher levels of both IL-12 and IFNy than the control patients. They also showed a decrease in the Th2-associated factors IL-4 and IL-10. Prof Jing-Ci Zhu, the supervisor of this study from the Third Military Medical University School of Nursing in China, explained, "Probiotic treatment appeared to swing the Th1/Th2 balance back towards normality and, in our study, had beneficial effects. Possibly due to the small size of our study there was no significant difference in the number of infections between the groups (9 for the probiotic group, 16 for the control patients). However probiotic therapy reduced the number of infections occurring after seven days, reduced the number of different antibiotics needed to treat in

Published: May 3, 2007 Updated: Nov. 3, 2011 Time flies -- and there are few things that dramatize that fact as vividly for a pediatric physician as learning that a patient you've cared for practically all her life is getting ready to go off to college. I've known Molly since she was a sprightly three-year-old. Now she's a high school senior who will be heading to a university in the Boston area next fall. When Molly's mom brought her by for a checkup recently, she asked my advice about protecting her daughter against two serious conditions that can affect teenagers -- both of which have received some frightening media attention over the past few years. One is meningococcal infection, which can strike suddenly and is sometimes fatal even in previously healthy teens. The other is a concern specifically for young women: HPV, or human papilloma virus, which can lead to cervical cancer. For this edition of "Your Child's Health," I asked my colleague Samuel Katz, MD, a specialist in pediatric infectious diseases and chairman emeritus of Duke's Department of Pediatrics, to share his thoughts on teen vaccines. He weighed in not only on the concerns raised by Molly's mother, but on other immunizations that may be helpful for older children and adolescents, especially those who may have missed earlier shots or require additional protection. --Dennis Clements, MD, PhD Parents most often think of immunizations for their children in the first 18 months of life and again when they enter school at age five or six. However, a new paradigm is emerging with a focus on teenagers or preteens. Three new vaccines have become available to help protect adolescent health. All have been endorsed by the American Academy of Pediatrics, the American Academy of Family Physicians, and the Advisory Committee on Immunization Practices (ACIP) of the Centers for Disease Control and Prevention. The first, licensed earlier in 2005, is a newer, more effective product to prevent meningococcal infection. The three principal groups of organisms responsible for meningitis and severe bloodstream infections in this country are the meni

In this encounter the Russians under General Peter Wittgenstein attacked and defeated a Franco-Bavarian force under Laurent Gouvion Saint-Cyr. In the aftermath of this success, the Russians took Polotsk and dismantled Napoleon's operations in Belarus. Wittgenstein's victory set the stage for the Battle of Berezina in November, in which three Russian armies converged on Napoleon from separate directions. While advancing on Moscow, Napoleon left a contingent of French and German troops at Polotsk to guard his northern flank against Wittgenstein. The French defensive bastion at Polotsk, alternately commanded by St. Cyr and Oudinot and located about 200 miles (320 km) east of the Polish border and about 150 miles (240 km) northwest of Smolensk, was extremely important to Napoleon for several reasons. By establishing a firm front at Polotsk, Napoleon kept Wittgenstein's command at bay. It was critical to French interests that Wittgenstein not be allowed to march south, because such an advance by the Russians would lead to Napoleon's Grande Armée, hundreds of miles to the east, being exposed to an attack in its rear while it was engaging the main Russian army near Moscow. Such a development would sever the Grande Armée's communications with Europe and it would be at risk of being encircled. Furthermore, the French position at Polotsk was important because it served to protect Vitebsk, which was one of three massive supply depots Napoleon had established in western part of Russian Empire (nowadays Belarus). These three supply depots—the other two being Minsk and Smolensk—were to fuel Napoleon's war effort in the winter should the Grande Armée need to continue the campaign longer than originally

About the artwork 'Venus and Anchises' was inspired by a verse from a poem called the 'Epipsychidion', by Shelley. 'Athwart that wintry wilderness of thorns Flashed from her motion splendour like the morn's, And from her presence life was radiated Through the grey earth and branches bare and dead; So that her way was paved and roofed above With flowers as soft as thoughts of budding love;' Richmond shows us the meeting at night, of Venus and her earthly lover, the Trojan shepherd Anchises, on Mount Ida. Venus, clothed in glowing pink and gold walks towards Anchises, who awaits her holding a lyre. Anchises, clad in a red shirt, appears to cower in the shadow of a tree. The usual penalty for mortals such as he for looking at a god or goddess was to be turned into stone. The picture is not a simple illustration of a mythical event, but demonstrates the transforming power of love. Night has turned into day. In the bottom right of the picture there are the dead leaves of autumn, but wherever Venus walks she becom

LESSONS FROM GEESE each goose flaps its wings, it creates an “uplift” for the bird following. By flying in a “V” formation, the whole flock adds 71% more flying range than if each bird flew alone. Lesson: People who share a common direction and sense of community can go further and get where they are going quicker and easier because they are traveling on the thrust of one another. Whenever a goose falls out of formation, it suddenly feels the drag and resistance of trying to fly alone and quickly gets back in formation to take advantage of the “lifting power” of the bird immediately in front. Lesson: If we have as much sense as a goose, we will stay in formation with those who are headed where we want to go. When the lead goose gets tired, it rotates back into formation and another goose flies at the point position. Lesson: It pays to take turns doing the hard tasks and sharing leadership – with people, as with geese, interdependent with each other. The geese in formation honk from behind to encourage those up front to keep up their speed. Lesson: We need to make sure our honking from behind is encouraging – not something less than helpful. When a goose gets sick or wounded or shot down, two geese drop out of formation and follow it down to help and protect him. They stay with the goose until it is either able to fly again, or dies. Then they launch out on their own with another formation or catch up to the flock. Lesson: If we have as much sense as geese, we will stand by each other in hard times as well as good. - Author Unknown

Better Students Ask More Questions. What is the diction in Cold Mountain? 1 Answer | add yours High School Teacher This is actually a rather vague question. When we think of the word diction, what is actually refered to is nothing more complicated than the choice of words that the author uses in his work. Therefore, what do you precisely mean or what do you want to find out? Looking at the novel we can see that there is a range of diction, including dialect in the speech that some of the characters use, to beautiful and amazing description of the natural world through which Inman walks and in which Ada toils. Slang and idioms are apparent in the dialect of some of the characters, and this certainly helps to recreate a picture of contemporary America during the Civil War. However, I would suggest that you either pick a specific passage and comment upon the diction used in that passage or try and narrow down your question in some way.

Trends and Challenges for Work in the 21st Century futurework: Chapter 3 - Box 3.3 -The Stress Box With the dramatic shift of women from households to workplaces, the hours American families work in paid jobs have increased significantly, making less time available for children and other family responsibilities. Competing demands of work and family have overburdened many Americans. Struggling to meet the needs of both job and family, they have little, if any, time left over for themselves. A 1997 report revealed that 26 percent of employees felt emotionally drained by their work often or very often, and 36 percent felt used up at the end of the workday often or very often.52 Such constant feelings of being overwhelmed can affect work, health, and family life. Sleep deprivation also contributes to high anxiety levels. Many workers try to squeeze more time out of a day by sleeping less. Research indicates that Americans are sleeping an average of seven hours per week night, an hour less than experts say is needed. All of these pressures can add up to a day-to-day routine full of fatigue, stress, and the sense of being pulled in too many directions with too little time. An obsolete network of resources, many argue, may exacerbate these pressures. Both in the community and the workplace, resources that do not sufficiently respond to the overburdened working familybe they traditional work scheduling, ad hoc child care, or even inflexible service hours for home repaironly make achieving a workable balance more of a struggle. Innovative thinkingin the workplace, in the community, and in government policyis needed to create options that better meet the needs of the American family.

All fires were extinguished on the eve of Beltane. This is one of the fire festival at which Balefires would be started across the country with a new fire that had been started by the Druid. All hearths would be rekindled with the fresh flame at sunrise. Actually the preparation for Beltane would start a few days before it, with the gathering of the nine sacred woods used for the kindling of the fire. At dawn the Bel-fire or Need-fire would be started and then torches fit from it to be carried home to relight the hearth fires. According to Robert Graves, the Beltane need-fire was kindled by drilling an oak plank with specific incantations and the fire had special properties. Irish traditions call for the first Beltane fire to be lit by the High King, then all the others were lit. A "little voice" tells me that the fires were lit by the Head Arch Druid and the other "fifths" or kingdoms were lit in an East, West, South, and North direction, by their Arch Druids or Lords of the area to form a circle of protection around the Island. It is celebrated as an early agricultural festival accompanying the first turning of the herds out to wild pasture. The rituals were held to promote fertility. The cattle were driven between the Belfires to protect them from ills and to ensure fertility. Contact with the fire was interpreted as symbolic contact with the sun. People also jumped the fire for fertility and prosperity. It was a time of fun and games. The time of planting is finished and a time of waiting begins. The Beltane Games were a time to test the young warriors against each other in friendly matches, archery contests, feasting, dancing, story telling and a chance for people to get together. It is also considered as the coming together of the God and Goddess in fertile union to add new life to the crops and hasten their growth. "Beltane" means "~Fire of Bel", the Sun God who's accession feast we now celebrate. Bel or Belinos, being associated with the Apollo and Baal. As a side note; Bel, Belinos, Balor or Belenus are traced back to Baal, they all mean Lord. They are more of a Fire God than a solar god. Also the Irish and Scottish word for the sun is "grian", another is "Mor", they are both feminine. So the Irish and Scots both thought of the Sun as female, a giver of life. As summer begins, weather becomes warmer, and the plant world blossoms, an exuberant mood prevails. It is a time of unabashed sexuality and passion. Young people spend the entire night in the woods "a-maying", and dance around the phallic Maypole the next morning. Older married couples may remove their wedding rings (and the restrictions they imply) for this one night. May morning is a magical time for "wild" water (dew, flowing streams, and springs) which is collected and used to bathe in for beauty, or to drink for health. Some Beltane traditions are: Make a rope out of the tail hair of Cattle and drag it in the dew chanting "Milk of this one down, milk of that one up, into my own big pail" to ensure a good milk supply. Bannocks cakes made with milk, eggs and oatmeal by hand and not suppose to come into contact with steel were made up until the end of the 19th century. To stop enchantments from fairies, rowan crosses were hung and people and animals sprinkled with water from sacred wells. The rowan branch is hung over the house fire on May Day to preserve the fire itself from bewitchment (the house fire being symbolic of the luck of the house. The May Queen (and often King) is chosen from among the young people, and they go singing from door to door throughout the town carrying flowers or the May tree, soliciting donations for a merrymaking in return for the "blessing of May". In some rituals, a King and Queen May symbolize the male and female principles of productivity This is symbolic of bestowing and sharing of the new creative power that is stirring in the world. As the kids go from door to door, the May Bride
