Perpetuate – Undulate
Stone is often seen as the epitome of permanence and stability. However, if you look at the geology of stone, it is far from the idea of eternity. The history of stones consists of the formation and decay of physical and chemical bonds. Solidifying, metamophizing, and sedimenting - viewed from a distance, the cycle of stone proves to be a process of constant change.
The work Perpetuate - Undulate deals with the relationship between form, process and artistic action. During the carving process, the stone is often rotated and turned over so that only a part of the entire stone can be worked on. With each turn, a new surface becomes visible which can be reshaped.
The resulting form from this process refers to this continuous movement and to the exploration of the idea of a permanent composition.This action is further referenced in the exhibition of the works. There is no predetermined way in which they are to be displayed, nor is there a set base. Limited to the duration of the exhibition, each time the works are shown differently and placed in different contexts. Each presentation offers different spatial conditions, from which new relationships emerge. In public space or in an exhibition room, the viewer's reception and interaction are directly related to the surrounding context.

Understanding T cell aging to improve anti-viral immunity
Huimin Zhang, Cornelia M. Weyand, Jörg J. Goronzy, Claire E. Gustafson
T cells are a critical component of the immune system and required for protection against viral and bacterial infections. However, the capacity of these cells to provide sufficient protection declines with age, leading to an increased susceptibility to and mortality from infection in older individuals. In many cases, it also contributes to poor vaccine-induced immunity. Understanding the basic biology behind T cell aging is key to unraveling these defects and, in turn, designing more effective vaccines and therapeutics for the older population. Here, we will discuss recent studies that have provided significant insight into the features of T cell aging, how these features may contribute to poor immune responses with advancing age and newer avenues of research that may further enhance anti-viral immunity in older individuals.

Casualty loss deductions: You can claim one only for a federally declared disaster
Casualty loss deductions: You can claim one only for a federally declared disasterUnforeseen disasters happen all the time and they may cause damage to your home or personal property. Before the Tax Cuts and Jobs Act, eligible casualty loss victims could claim a deduction on their tax returns. But there are new restrictions that make these deductions much more difficult to take.
What’s considered a casualty for tax purposes? It’s a sudden, unexpected or unusual event, such as a hurricane, tornado, flood, earthquake, or fire; an accident or act of vandalism; or even a terrorist attack.
Unfavorable change
For losses incurred in 2018 through 2025, the TCJA generally eliminates deductions for personal casualty losses, except for losses due to federally declared disasters. For example, during 2019, there were presidential declarations of major disasters in parts of Iowa and Nebraska after severe storms and flooding. So victims there would be eligible for casualty loss deductions.
Special timing election
If your casualty loss is due to a federally declared disaster, a special election allows you to deduct the loss on your tax return for the preceding year. If you’ve already filed your return for the preceding year, you can file an amended return to make the election and claim the deduction in the earlier year. This can help you get extra cash when you need it.
Calculating personal losses
To calculate the casualty loss deduction for personal-use property in an area declared a federal disaster, you must take the following three steps:
1. Subtract any insurance proceeds.
2. Subtract $100 per casualty event.
Important: Another factor that now makes it harder to claim a casualty loss is that you must itemize deductions to claim one. For 2018 through 2025, fewer people will itemize, because the TCJA significantly increased the standard deduction amounts. For 2019, they are $12,200 for single filers, $18,350 for heads of households, and $24,400 for married joint-filing couples.
We can help
These are the rules for personal property. Keep in mind that the rules for business or income-producing property are different. If you have disaster-related losses, we can help you navigate the complex rules.

A New Kind of Black Hole
Feedloader (Clickability)
Until now, there have been two known types of black holes: stellar-mass black holes that are several times more massive than our sun and are created when really big stars die out, and supermassive black holes that are millions to billions of times the mass of the sun and which sit in the center of most, maybe all, galaxies, including our own Milky Way. While astrophysicists have been fairly certain of how the smaller black holes are created, the creation of the larger ones has been largely a mystery. The main hypothesis is that they are formed from the merger of multiple medium-size black holes. But no one had ever confirmed the existence of black holes of this size. Until this week.
A team led by scientists at the Centre d'Etude Spatiale des Rayonnements in France reports in today's issue of Nature that they have found a black hole that is more than 500 times more massive than the sun. They found an X-ray source, now named Hyper-Luminous X-ray source 1 (HLX-1), on the edge of the galaxy ESO 243-49 that has a maximum X-ray brightness about 260 million times that of the sun. As gas falls into a black hole, energy is released, much of it in the form of X-rays. Only a medium-size black hole could create an X-ray signature that bright, the scientists say.
"This is the best detection to date of such long sought after intermediate mass black holes," lead author Sean Farrell said in a statement. "Such a detection is essential. While it is already known that stellar-mass black holes are the remnants of massive stars, the formation mechanisms of supermassive black holes are still unknown. The identification of HLX-1 is therefore an important step towards a better understanding of the formation of the supermassive black holes that exist at the center of the Milky Way and other galaxies."

Growing Plants with LED’s
In some dictionaries life is defined, as a power that demonstrates a purpose to feed, process matter into energy, grow, and reproduce. Life means existence, a state of being. No matter how we look at the definitions, one thing is clear: life is the energy driving the universe and all its happenings, and for humans and all the living organisms, life, or being alive, is a force entirely dependent on special factors such as air, water, light and much more elements that interact to support existence in all its forms and each of them is equally important for the survival of the species…
All these resources are an abundant presence on Earth, but nothing can last forever. Polluted water is not usable, air is itself contaminated on many parts of the Globe, mineral resources are non-renewable and lightâÂ?¦ natural light has its benefits but also it can constitute a danger for the species if we consider the UV emissions reaching Earth’s atmosphere.
Light influences all life on Earth directly or indirectly. Plants need light for photosynthesis, therefore for growing and in exchange they forward their energy to the animals that consume them. At the same time animals need light for a harmonious evolution and even nocturnal ones require some low level illumination. Lack of natural light causes various disorders by people and the same happens by plants and animals.
UV light can harm living organisms in several ways. For example plants overexposed to UV light reduce size and are more susceptible to specific diseases. The light coming direct from the sun sends to earth three types of ultraviolet: UV-A (380-315 nm), UV-B (315-280 nm) and UV-C (280-10 nm). Due to the absorption in the atmosphere’s ozone layer, 99% of the ultraviolet light that reaches the Earth’s surface is UV-A.
While UV-A causes plants only a little harm, UV-B, which is a shorter wavelength, can damage plant tissue and in humans it can cause skin cancer. UV-C is the part from the UV spectrum with the shortest wavelength and all bacteria and virus get deadly sunburn in an artificial UV-C filter system. Certainly UV light has its paradoxes: even if it is harmful in one way, it is useful in another. Medicine is using this artificial UV light to cure difficult skin conditions such as psoriasis eczema, lymphoma, acne, a-topic dermatitis, and so on.
Fact is that plants don’t need too much UV light, on the contrary. This is why crop production with artificial light means that will eliminate the dangerous UV emissions seems to be the next logical step.
Growing Plants Technology – Crop Production Systems
The target of crop production systems is to develop innovative technologies that lower the costs of harvest and ensure ecologically aware crop farming.
The crop production systems do not disregard important factors that influence plant development: temperature, humidity, light, carbon dioxide, water and nutrients. All these blend to create the ideal environment for a plant to grow and reproduce as well as they influence size, seeds, plant health and so on. Each plant will progress in its own manner, depending on the environment. Since a long time already biologists are studying the factors that influence vegetation’s evolution. Light is a very important factor and researchers were able to determine exactly which wavelengths are the ones plants need for their growth. Some colours in light rays are essential for good plant evolution. Vegetation mirror and receive a small amount of energy from yellow and green emissions of the visible spectrum. However the red and blue fractions of the light continuum are the most valuable energy resources for plant life, and plants necessitate more red (625 to 675 nm) than blue (400 to 470nm). Yellow (525 nm) triggers photosynthesis too, while IR influences seed spurring and UV colour and scent.
How Light Colour Influences Plant Growth
Blue light: plants react to the intensity of blue light. Lessening the blue light will cause poor growth – the strength of the radiation in any other part of the spectrum is not as important as the intensity of the blue, which shapes height and quality.
Red (660 nm) and infrared (730 nm) (also known as IR or far red) light: Intensifying the total of IR in relation with 660 nm red makes plants grow tall and thin. On the other hand if red is increased while IR diminished, plants will be short but thick. Plant reactions are not linear with the red/far red ratio and they can also vary in their response to red and far red light.
Ultraviolet light (UV): While overexposure is dangerous, small amounts of UV light can be beneficial for the flora. In many cases UV light is a very important cause for colours, taste and aroma. But UV-C and UV-B are believed to stop plant spread and this is why they have to be removed from the light under which plants are developed in green houses by UV stabilisers or glass. Removal of the UV up to 400nm is might be effective also in case of virus carrier insects (as insects see partly in UV).
Direct light from the Sun distributes the useful wavelengths only on special times of the day and in small quantum enough for a harmonious growth in some parts of the Earth, yet not enough on others.
Crop production systems are dealing with such problems and find ways to replace natural light with artificial light. The idea of growing plants under artificial illuminators is not new at all. Long time ago NASA started to grow plants in space, and the results were astonishing. Nowadays we know that by using the correct wavelength plants develop harmonious and healthy, sure if they have all the other conditions ensured. Yet getting light of the correct wavelength is not an easy task, especially if one takes into account the costs and efficiency of such light sources.
LED Lighting Technologies to Substitute Natural Light
To substitute natural light is quite difficult also if you consider how hard it is to obtain light near the visible part of the spectrum with traditional luminaries. Light emitting diodes are here to change that difficulty.
SSL (solid state lighting) is the youngest lighting technology and by now is believed to be more efficient than incandescence and fluorescence due to the fact that SSLs produce light at or near the visible part of the spectrum and as a result the emitted light can be used straight or with minor conversion. One of the most important advantages is that SSL technology has eliminated damaging components from the light sources (remember: light emitting diodes contain no ultraviolet unless they are produced as UV LEDs).
NASA is already using SSL in its space farming systems. The reasons are quite simple: incandescent or fluorescent lamps are not efficient enough for such purposes, because they consume a lot of electrical power, generate heat and contain electrodes that burn out (maintenance costs are high). This is why NASA’s plant physiologists started to work with light emitting diodes (blue and red) to grow salad plants such as lettuce and radishes. The researchers found our that blue and red light is essential for plant growth and, in general, a percentage of 8% blue LEDs and 92% red LEDs, both with the same frequency and relative intensity per LED, are enough for a harmonious evolution. Blue has a smaller influence than red; however a percentage between 1% and 20% of blue light can be selected, depending on the plants and their growth requirements. The NASA scientists have tried to create the most cost and energy efficient light sources possible, and this is why they have eliminated from the fixtures other colours normally found in white light. “What we’ve found basically is that we are able to limit the amount of colour we give to the plants and still have them grow as well as with white light.” said the research scientist Greg Goins of Dynamac Corp. LEDs are not the only ones efficient for growing plants: sulphur microwave lamps are the most efficient light sources known to man, that can generate as much light as the noonday sun, perfect for illuminating large-scale systems such as greenhouses. For smaller applications, such as indoor gardens, LEDs seem to be the right choice.
Pros and Contras LED Grow Light Systems
There are some pro and contras when it comes to LED grow light systems. When planning such farming alternatives, one has to carefully consider that plants do use light at all wavelengths from UV to IR, as explained above, needed to convert water and carbon dioxide into sugars. Some plants use more red and blue, less green and yellow, while others use green as much as they use red and blue, as well as the light in between. If LEDs are chosen for brightness, there is one aspect to be underlined: they just look bright because their light is unidirectional and their size is small. To get enough light there are many LEDs needed, that’s why the cost of LED arrays or LED modules is so high. LEDs can be calibrated to emit only the light most efficient for the plants, but not all the light plants need. This is why such light sources are recommended only in places where direct light from the sun is not enough or inexistent – space farming for example. Also in places where light from the sun is too strong and can harm the plants with the high emission of UV, LEDs are a good choice, because UV filters are stopping some of the useful wavelengths too. In wintertime the weather conditions restrain crop production; this is why greenhouses need a substitute for the natural light. It makes sense to deliver plants the minimum lighting conditions for a corresponding evolution.
There are some significant factors to take into account when choosing light sources for such applications and these are low costs, energy efficiency, long life, and ability to withstand voltage fluctuations, modularity in order to grant users the possibility to assemble arrays that gives as much light as needed, where needed. LEDs are pretty efficient in the conversion of electric power to light, in any case more than traditional fluorescent and incandescent lamps. Due to the fact that light emitting diodes can be manufactured to emit a specific wavelength and are expected to have a long life span (from 50000 hours up), many plant physiologists are considering using them in large applications. Compared to LEDs most of the other traditional lamps have to be replaced every two-three years. Other features such as choice of viewing angles, control options, instant turn on times, cold start and much more, recommend the semiconductor devices. At present this is still an expensive technology, but in time LEDs efficiency will be maximized while prices reduced and these details are a good base for future planning.
It is so far clear that in order to produce efficient LED grow light systems a lot of investigation is necessary. It is not enough to mount some blue and red LEDs on a PCB and say: “that’s it; we’ve got the plant growing LED system”. NASA created only a mechanism that delivers the minimum amount of light needed for some plants. For greenhouses on Earth other questions need to be answered: how much blue, how much red? What about the other colours, what about UV and IR? Should the light pulse? Should it be dimmed in the morning and evening to imitate natural conditions (sunrise and sunset?). Do plants need light at night? And the list remains opened.

A neural approach to relational reasoning
Consider the reader who pieces together the evidence in an Agatha Christie novel to predict the culprit of the crime, a child who runs ahead of her ball to prevent it rolling into a stream or even a shopper who compares the relative merits of buying kiwis or mangos at the market.We carve our world into relations between things. And we understand how the world works through our capacity to draw logical conclusions about how these different things – such as physical objects, sentences, or even abstract ideas – are related to one another. This ability is called relational reasoning and is central to human intelligence.We construct these relations from the cascade of unstructured sensory inputs we experience every day. For example, our eyes take in a barrage of photons, yet our brain organises this blooming, buzzing confusion into the particular entities that we need to relate.Read More

MFI is the abbreviation for the Money Flow Index, an oscillating indicator of technical securities analysis. It was first published by Gene Quong and Avrum Soudack and is an extension of the Relative Strength Index (RSI). The MFI also has a volume component.
One of the starting points for the idea of the Money Flow Index was that striking turning points in the price trend are marked by an increase in volume. Indicators that only take price changes into account cannot show the whole picture. The Money Flow Index is designed to measure the strength of money as it flows in and out of the market.
How the MFI is calculated
The MFI fluctuates between 0 and 100 and indicates whether a security tends to be overbought or oversold. As with the RSI, the basis for calculating the MFI is the typical price of a security, which is the average of the highest, the lowest and the closing price of a day. If this increases compared to the previous trading day, this increase indicates a positive money flow and the MFI climbs.
Formula: MFI = 100 - (100/(1 Money Ratio))
Conversely, if there is a fall in prices, there is a negative money flow and the MFI slides. Due to the multiplication of the prices with the daily turnover, which usually increases with strong price swings, the swings of the MFI are significantly higher than those of the RSI. This makes market exaggerations even more obvious.
Recommendations for analysts
The MFI generates buy signals especially when the indicator is in the oversold zone between 0 and 20 points and crosses the border to the neutral zone. On the other hand, it is advisable to sell securities when the MFI has risen into the overbought zone between 80 and 100 and then falls downwards into the neutral zone.
If the MFI changes as a result of new data in such a way that the 50 line is crossed from below to above, this is generally interpreted as a buy signal. If, on the other hand, the centre line is crossed from top to bottom, this indicates a sell signal.
Likewise, it is possible to derive indications from the comparison of MFI and price value. If, for example, the price of a security is still showing an upward movement while the MFI is already falling, these are signs that an upward trend will soon end.

ROC, a trend-following indicator
Here is explanation used by thai traders: ตัวบ่งชี้การติดตามแนวโน้ม ROC เป็นไปตามแนวโน้มราคาของการรักษาความปลอดภัยพื้นฐานและทําเครื่องหมายโซนการกลับรายการแนวโน้มค่อนข้างแม่นยํา. ยิ่งการตั้งค่าช่วงเวลาสั้นลงใน Exness เป็นโบรกเกอร์ฟอเร็กซ์ระดับโลก ยิ่งตัวบ่งชี้แกว่งไปมารอบ ๆ เส้นกลางและยิ่งตอบสนองกับความผันผวนของราคาที่น้อยลง.
he trend-following indicator ROC follows the price trend of the underlying security and marks its trend reversal zones quite accurately. The shorter the setting of the intervals, the more the indicator oscillates around its centre line and the faster it reacts to smaller price fluctuations.
Trading signals with the ROC
If the ROC is in positive territory and shows a rising tendency, this indicates a continuation of the upward trend. Similarly, a falling ROC in the same range indicates a possible end to the upward movement. If the ROC is in negative territory while showing an upward tendency, this indicates a continuation of the downward trend. Correspondingly, a falling ROC in the same range indicates a possible end of the downward movement.
With the ROC, classic buy signals arise when the indicator crosses the centre line from the bottom to the top. In contrast, sell signals on the ROC occur when the Rate of Change crosses the centre line from top to bottom.

To do this, radio emitters use a carrier wave to transport the audio signal. This wave is a high frequency signal which is fixed for each broadcasting site. In our case, we receive Option Musique on 765 kHz.
So, the sender applies the audio signal on the carrier wave, which is called amplitude modulation (AM).
The Receiver
The receiver has to oscillate on the same frequency as the transmitter it wants to receive. This oscillation is created by the variable condensator and the inductivity, which then receive the modulated signal.
The diode then will dispose of half of the wave, which is called the demodulation.
This demodulated signal can then be heard with a speaker of high impedancy, about 1 kOhm.
Would the signal not be demodulated it could not be heard because the two halfs of the wave would compensate each other.

The Eugenics Movement ℹ
Facebook Twitter
The plot to create Britain’s super race
Now 77 and herself an accomplished academic still teaching in her specialist area of child psychotherapy, Hopkins remembers standing on the deck as the ship pulled out into the Mersey, holding the hand of a three-year-old girl who needed consoling after she had dropped her teddy bear over the side. “It was a dreadful voyage,” she says. “Everyone was very seasick.” And no one had any idea when they would be coming back. In this, they were not so unique. Among those who saw out the war in North America were the future Shirley Williams, as well as Martin Gilbert, later to become Winston Churchill’s official biographer, Eric Hammond, later a combative trades union leader, novelist Lynne Reid Banks and a couple of Bonham Carters.

The term eugenics comes from the Greek roots for "good" and "generation" or "origin" and was first used to refer to the "science" of heredity and good breeding in about 1883. Within 20 years, the word was widely used by scientists who had rediscovered the work of Gregor Mendel. Mendel had meticulously recorded the results of cross-breeding pea plants, and found a very regular statistical pattern for features like height and color. This introduced the concept of genes, opening the field of genetics to a tumultuous century of research. The trappings of science, anyway. Local eugenics societies and groups sprang up around the United States after World War I, with names like the Race Betterment Foundation.

California was considered an epicenter of the American eugenics movement. Eugenics was born as a scientific curiosity in the Victorian age. How? Hitler studied American eugenics laws. Eugenics. While eugenic principles have been practiced as far back in world history as Ancient Greece, the modern history of eugenics began in the early 20th century when a popular eugenics movement emerged in Britain[8] and spread to many countries, including the United States and most European countries.

How to build digital marketing metrics
The digital marketing industry has come a long way since the days when companies used to gather data on what people bought, how they shopped, and where they lived.
Now, the tools are on the rise.
In fact, more than 1.8 million Canadians use the platforms each month.
But how to use the data to understand the buying behavior of your customers?
In this video, CMOs of digital marketing companies and marketers discuss what they use to understand who they are, what data they collect and how to integrate it into marketing campaigns.
A digital marketing marketing analytics company will use data collected to help you understand your customer’s buying behavior, whether that’s buying through social media or via direct mail.
In this tutorial, we’ll go over the different metrics that can be used in a digital marketing analytics analysis and how they can help you with your marketing strategy.
Analytics are tools that help you identify trends and patterns across a group of data points.
Analytics can help your business achieve better outcomes by measuring what works and what doesn’t in a given market, and what your users want in a particular digital market.
The goal of digital advertising is to reach as many people as possible through different channels, so it’s important to know how to collect data to support your campaigns.
A digital marketing team can use the metrics that come from the platforms and the analytics tools that they are using to understand how to best engage with your users.
Here are the different types of data that can come from digital marketing platforms:Social media: These platforms collect data about who is visiting your website, what your ads are being seen, and the number of times users click through to your website.
Facebook: Facebook’s platform uses data from users’ activity on Facebook to determine how much time users spend on the platform.
The platform collects the activity of your users, so if users spend less time on Facebook than they do on their other social networks, it will be an indicator that users are less engaged with your website or with your ads.
Twitter: Twitter collects information about users who use the platform to track how often they respond to messages, as well as the number and frequency of their interactions with your advertisers.
These analytics can be helpful in understanding how to optimize your digital campaigns to increase engagement and retention.
Analytics on social media are also useful when looking at the demographics of your audience.
For example, if you want to understand what your audience is, it can be a good way to understand whether your digital campaign can work with that demographic.
Advertising agencies also collect social media data.
These platforms are also great for analyzing demographics, since the platforms collect demographic data on users.
For a digital agency, there are a few key factors to consider when looking for the best data collection platform.
It’s important that your digital ad campaigns are focused on the demographics that are key to your brand and your customers.
Also, remember that you need to use your data to help build your digital marketing strategy and deliver the best digital advertising experience possible.
Analytic tools are the tools that can help create digital marketing insights.
There are many different analytical tools that will help you create digital campaigns.
The most important of these tools are social media analytics, analytics for advertising, and data collection platforms.
Social media analytics tools collect and analyze the social media activities of your digital audiences.
In the past, these platforms were used for advertising purposes, but now they are being used for the analysis of digital ads and digital marketing campaigns in the digital marketing arena.
Social media analytics can help with the understanding of your target audience, and help you tailor digital campaigns based on that audience.
You can use social media tools to track users’ engagement and activity on social networks and to build better advertising experiences.
Analytical tools can also be used to create digital ad placements that optimize your ads based on demographic demographics.
For instance, you can analyze how people respond to ads that include demographics based on the demographic of the target audience.
Analysts use social analytics to identify how people interact with your advertising and marketing campaigns and to improve your ad placement campaigns.
These tools can help to build an understanding of how people use the ad network to make their purchases, as they will help them to understand where they buy from, how much they spend and how well they feel about the product.
You should also consider the use of analytical tools for analytics that relate to your digital advertising campaigns.
For example, analytics on social marketing platforms can help understand which demographics people are most likely to purchase from and how that demographic is likely to respond to your ads in different types and channels.
Analytics on social ads can also help you better understand how your campaign is performing in terms of engagement and conversion.
Social analytics can also aid in the creation of digital ad placement strategies that align with the demographics and buying behavior patterns of your customer base.
For digital marketers, it is also important to understand your audience’s demographics, and to understand their purchasing behavior.
This can help guide the placement of digital advertisements that

The Coordinates Section
Previous pageReturn to chapter overviewNext page
The optional COORDINATES section defines the coordinate geometry of the problem.
Each geometry selection has an implied three-dimensional coordinate structure. In 2D and 1D geometries, the solution if the PDE system is assumed to have no variation in one or two of the coordinate directions. The finite element mesh is therefore constructed in the remaining space, and derivatives in the absent coordinates are assumed to be zero.
In 3D geometry the X & Y coordinates are the projection plane in which a figure is constructed, and the Z coordinate is the direction of extrusion.
The first coordinate in the order of listing is used as the horizontal axis in graphical output, while the second is used as the vertical axis.
The basic form of the COORDINATES section is:
where geometry may be any of the following:
Coordinate system
Modeled Coordinates
Cartesian (X,Y,Z)
Cylindrical (R,Phi,Z)
Spherical (R,Theta,Phi)
Cartesian (X,Y,Z)
Cylindrical (Z,R,Phi)
Cylindrical (R,Z,Phi)
Cartesian (X,Y,Z)
If no COORDINATES section is specified, a CARTESIAN2 coordinate system is assumed.
Renaming Coordinates
A second form of the COORDINATES section allows renaming (aliasing) of the coordinates:
COORDINATES geometry ( 'Xname' [,'Yname' [,'Zname'] ])
In this case, the 'Xname' argument renames the coordinate lying along the horizontal plot axis, and 'Yname' renames the coordinate lying along the vertical plot axis. 'Zname' renames the extrusion coordinate. Names may be quoted strings or unquoted names. Renaming coordinates does not change the fundamental nature of the coordinate system. In cylindrical geometries, for example, the radial coordinate will continue to be the radial coordinate, even if you name it "Z".
In time-dependent problems, the time coordinate may be renamed using TIME ('Tname') in the COORDINATES section :
COORDINATES geometry TIME ('Tname')
This may be used in conjunction with the renaming of spatial coordinates.
Differential Operators
Renaming coordinates causes a redefinition of the differential operators. DX becomes D<Xname>, etc.
The DIV, GRAD, and CURL operators are expanded correctly for the designated geometry. Use of these operators in the EQUATIONS section can considerably simplify problem specification.
Other Geometries
Since FlexPDE accepts arbitrary mathematical forms for equations, it is always possible to construct equations appropriate to an arbitrary geometry.
For example, using the CARTESIAN2 coordinate system and renaming coordinates, one can write the heat equation for cylindrical geometry as
COORDINATES cartesian2("R","Z")
u: dr(k*r*dr(u)) + r*dz(k*dz(u)) + r*source = 0
This equation derives from expanding the DIV and GRAD operators in cylindrical coordinates and multiplying by the volume weighting factor "r", and is the same as the equation that FlexPDE itself will construct in XCYLINDER geometry.
Coordinate Transformations
The function definition facility of FlexPDE can be used to simplify the transformation of arbitrary coordinates to Cartesian (X,Y,Z) coordinates.
The example problem "Samples | Usage | polar_coordinates.pde" uses this facility to pose equations in polar coordinates:
dr(f) = (x/r)*dx(f) + (y/r)*dy(f) { functional definition of polar derivatives... }
dphi(f) = (-y)*dx(f) + x*dy(f) {... in cartesian coordinates }
EQUATIONS { equation expressed in polar coordinates }
{ (and Multiplied by r^2 to clear the r=0 singularity) }
U: r*dr(r*dr(u)) + dphi(dphi(u)) + r*r*s = 0
Graphic output using this procedure is always mapped to the fundamental Cartesian coordinate system.

The Multidimensional Niche
Species have limited abilities to tolerate extremes of environmental conditions. In other words, for all environmental factors there are upper and lower bounds of intensity that organisms can endure. For example, a particular species of plant or animal might be able to survive over an extended period of time within a zone of temperature bounded by certain high and low extremes. Extended exposures to hotter or colder temperatures cannot be tolerated, and the species will not occur in such environments. The boundaries of temperature tolerance can be represented as a component of the niche of the species in a single dimension-that of environmental temperature.
There are similar boundaries of tolerance for other environmental factors including climatic, chemical, and habitat variables, each of which can be similarly represented as a component of the larger niche in a single dimension. Conceptually, the niche of the species can be viewed as a multidimensional composite in which all of the boundaries of tolerance of diverse environmental influences are assembled into a single, multivariate factor. This is known as the fundamental niche, or the multidimensional zone (also known as a hypervolume) of environmental tolerance, in which an individual can potentially survive or in which a species can maintain viable populations.
However, in natural ecosystems species are rarely faced with habitat opportunities that are only defined by the boundaries of their tolerance of diverse environmental factors. The actual utilization of the fundamental niche is also significantly influenced by ecological interactions of various sorts. For example, other species may have similar tolerances of environmental factors. These species will seek to utilize some portion of the environmental opportunities that are available, resulting in the ecological interaction known as competition. Competition exerts a very important influence on the ability of species to optimally exploit their fundamental niche and on the structure of ecological communities. If species have very similar fundamental niches, then competition between them will be intense. In extreme cases this can cause one species to be eliminated from the community through a process known as competitive exclusion. More often, however, species are displaced by competition to particular zones within their fundamental niche.
Exploitation of the fundamental niche is also constrained by other ecological interactions such as predation, parasitism, and disease. All of these can restrict the opportunities for species to exploit their fundamental niche in an optimized fashion. Ecologists define the realized niche as the multidimensional hypervolume of environmental factors that species actually manage to exploit in nature in view of the powerful influences of competition, predation, parasitism, and disease.
Species must be present in the habitat in order to realize the benefits of some part of the range of their fundamental niche. If a location containing potentially suitable habitat cannot be colonized by a species, then it cannot utilize that part of its fundamental niche.
Realized niches are variable over time because they can respond to changes in the nature of ecological interactions. The introduction of a new, more capable competitor can eliminate an original species from its ecological community through competitive exclusion. A similar effect can be caused by introduced predators, parasites, and diseases. In contrast, the elimination of an important competitor, predator, parasite, or disease can release a species from a previously controlling influence, allowing it to expand the dimensions of its realized niche.
In general, the realized niche of species does not represent the environment conditions to which they are optimally adapted. The combined influences of diverse ecological interactions commonly relegate species to sub-optimal portions of their fundamental niche.
Ecological communities can be viewed as populations of various species that co-occur in space and time. Each species in the community maintains its populations by utilizing the opportunities available in its realized niche within the larger habitat. The number of species that can be maintained in the community and their relative abundance are determined by the diversity of niche opportunities, their stability over time, and the intensity of ecological interactions. The influences of these factors are optimized in old-growth tropical rain forests which maintain a greater diversity of species than any other terrestrial ecosystem. Among oceanic ecosystems, species diversity is greatest in coral reefs.

Character Essay
Quote: “You may have to fight a battle more than once to win it”.
Margaret Thatcher (first female British prime minister, 1925-2013)
In order to win any fight, battle or war, it may have to be fought more than once. It may even have to be fought more than two, three or four times. Not all fights can ever just end with one fight, they may take several fights whether they take days, weeks, months, or even years. This is because all battles are not the same. Some battles do not end quickly because when one side is attacked, the other side will respond with the same force they are attacked with, and each side will give their effort to win because that is the importance of winning, as long as you continue fighting and not giving up, it may take one baby step at a time or one humongous step. Throughout history, there are many notorious battles that are remembered even now and those battles will always be remembered because they made not only have they made history, but importance and meaning.

Head Toward the Light
Getting Started with Silverlight 1.0
By Dan Wahlin
The overall acceptance of AJAX and Flash technologies in Web applications has led to the creation of more and more rich applications that provide an enhanced next generation user experience. End users are accustomed to visiting Web sites that show advertisements and media clips with Flash and load dynamic content with AJAX. With the release of Silverlight 1.0, Microsoft has thrown their hat into the rich Web experience ring and provided a nice foundation for developers to build upon. Silverlight works on Windows and Mac operating systems, and in multiple browsers, including Internet Explorer, FireFox, and Safari.
If you ve heard about Silverlight, but haven t yet had a chance to experiment with it, it s a browser plug-in that can play audio and video, perform animations and transformations, and enhance the way data is displayed in a Web page. You can download the plug-in and associated software development kit (SDK) and view many eye-catching Silverlight demos at
Silverlight 1.0 is all about a declarative language named XML Application Markup Language (XAML), as well as JavaScript. It can also leverage various AJAX frameworks, including ASP.NET AJAX, to obtain data dynamically. Many demos focus on how audio and video can be added to Silverlight applications because it s very good at these types of tasks. But Silverlight can be used in many other scenarios, from games to data display. In this article, I ll provide an introduction to various features available in Silverlight 1.0, and describe the different pieces needed to make Silverlight work. Let s get started by looking at the overall architecture of Silverlight 1.0.
Putting the Pieces Together
Silverlight has several key technology players that are needed to make things work in a Web page. First, XAML is used to define the content displayed by Silverlight. XAML is an XML-based mark-up language that also is used by Windows Presentation Foundation (WPF). The version of XAML available in Silverlight 1.0 contains a sub-set of the overall XAML specification, as the Silverlight plug-in needs to stay small to allow for quick downloads and installations. Using XAML, you can define shapes, such as rectangles and ellipses, embed .wmv and .wma media files, perform snazzy animations to move objects around, and transform objects to perform interesting effects. I ll provide an introduction to XAML in the next section of the article.
In addition to XAML, Silverlight 1.0 relies on JavaScript to create a Silverlight control instance at run time, and to programmatically access various objects and media defined in XAML. In cases where you need to dynamically add content to Silverlight, you can use JavaScript to perform asynchronous operations (AJAX operations) without reloading the entire Web page. Any AJAX framework can be used, from Prototype to ASP.NET AJAX, to retrieve data and inject it into Silverlight.
Figure 1 shows the overall Silverlight architecture as defined in the Silverlight 1.0 SDK. You ll see that it provides support for decoding media, working with events, rendering content and text, parsing XAML, downloading objects used by Silverlight, performing animations, plus more.
Figure 1: The architecture of Silverlight 1.0.
Now that you ve seen the main Silverlight components, let s see how they work together. The basic steps to use Silverlight in a Web page are shown here:
1) Create a new Web site in Visual Studio or Web Developer Express.
2) Add the Silverlight.js file to the Web site.
3) Create an XAML file that Silverlight will consume.
4) Add a Web page with a
container that will hold the Silverlight control.
5) Add a custom CreateSilverlight.js file to the site.
6) Call Silverlight.createObject or Silverlight.createObjectEx within CreateSilverlight.js to create a Silverlight instance at run time.
7) Reference the Silverlight.js and CreateSilverlight.js files in the Web page using the
Figure 2: Referencing the Silverlight.js and CreateSilverlight.js files and defining a container div.
function CreateSilverlight()
parentElement: document.getElementById('divSilverlight'),
id: 'slControl',
properties: {
width: '500',
height: '500',
isWindowless: 'false',
version: '1.0'
events: {
onError: null,
onLoad: null
context: null
Figure 3: Using the Silverlight.createObjectEx method to define the location of the XAML file and instantiate the Silverlight control with a specified height, width, background color, and version.
Getting Started with XAML
XML Application Markup Language (XAML) is a declarative language used to define shapes and text, define events, embed media, and perform animations and transformations. Silverlight applications are typically separated into one or more canvases using a Canvas element, much like Web pages are divided up using div elements. In fact, you can use a Silverlight canvas in similar scenarios where you d use a div in HTML.
Every Silverlight XAML file starts with a root Canvas element that defines a default namespace of (you may see an older version of the namespace in some Silverlight samples, as well). Child elements needed by the application are then placed within this root Canvas element. Figure 4 shows an example of an XAML canvas that contains a nested child canvas, along with other elements.
Height="300" Width="300" Background="#efefef">
Width="200" Height="150" Fill="Yellow" />
Foreground="Maroon" FontFamily="Verdana" FontSize="24"
FontWeight="Bold" Text="Hello, From Silverlight!">
Figure 4: Defining a canvas in XAML.
Looking through the XAML code, you ll see that Canvas elements can contain children. For example, the second Canvas element contains Rectangle and TextBlock child elements.
The second Canvas element defines where it should be displayed within its containing parent Canvas by using the Canvas.Left and Canvas.Top attributes (referred to as attached properties ). In this case, the child Canvas should be displayed 10 pixels from the left of the parent Canvas and 10 pixels down from the top. Likewise, the Rectangle and TextBlock elements also define where they should be displayed relative to their containing Canvas using the same attributes. In addition to positioning information, the Rectangle also defines its name, height, width, and background color. The TextBlock defines its name, foreground text color, font family, font size, font weight, and text using the appropriate attributes. Figure 5 shows an example of the output generated.
Figure 5: Output generated from running the XAML shown in Figure 4.
Figure 6 shows another example of an XAML file that defines different types of shapes, including a Rectangle, Ellipse, and Line. The output generated by this XAML when it s loaded and run by a Silverlight control is shown in Figure 7.
Canvas.Left="10" Canvas.Top="20" Stroke="Black"
StrokeThickness="3" Fill="Blue"/>
Stroke="Black" StrokeThickness="5"/>
Canvas.Left="36" Canvas.Top="80"
FontWeight="Bold" Text="Hello From Silverlight!">
Figure 6: Defining shapes using XAML elements.
Figure 7: Output generated by the XAML code shown in Figure 6.
XAML also provides a way to define audio or video within a Silverlight canvas. Supported media types include MP3, WMA, and WMV. Adding media to a Silverlight application is accomplished by using the MediaElement tag. MediaElement defines the source of the media, as well as how it should fill its container (in cases where video is being displayed). This is done using the Source and Stretch attributes, respectively. The Stretch attribute accepts the values shown in Figure 8.
The media content is resized to fill the container s dimensions. The aspect ratio isn t preserved when using this value.
The media content is shown in its default size.
The media content is resized to fill the container s dimensions, but the original aspect ratio is preserved.
The media content is resized to fill the container s dimensions, but the original aspect ratio is preserved. The source content is clipped to fit in the destination dimensions if the aspect ratio of the destination rectangle differs from the source.
Figure 8: Values accepted by the Stretch attribute.
Figure 9 shows an example of using the MediaElement tag to embed a .wmv file in a canvas. Because the MediaElement s AutoPlay attribute is set to True, the video will automatically start playing once the Silverlight canvas has loaded and the video file has buffered enough frames into memory. End users can also interact with media files through events to start, stop, and pause media. I ll provide an introduction to handling XAML events later in this article.

Figure 9: Adding media to a Silverlight canvas using the MediaElement tag.
Although discussing each of the elements and attributes available in the Silverlight XAML specification is outside the scope of this article, the Silverlight 1.0 SDK provides excellent coverage and, in many cases, provides examples of using them. You ll also find additional details about XAML at and on my blog (
Tools such as Microsoft s Expression Blend 2 can greatly simplify the process of creating XAML code and are recommended when working with large amounts of XAML. You can find out more about Expression Blend 2 at
Interacting with XAML Objects
Aside from look and feel, XAML also allows events and event handlers to be defined so that end users can interact with objects defined in a Silverlight canvas. Events are defined in a similar manner to HTML element events: they re placed directly on the target element. Figure 10 shows an example of defining different events and their associated event handler functions. The JavaScript event handler functions are typically placed in an external JavaScript file, but can be embedded directly in the page (as shown in Figure 11).
Width="300" Background="#efefef">
FontWeight="Bold" Text="Hello from Silverlight!">
Figure 10: Adding events and event handler references to XAML.
var _TB = null;
function ShowLoad(sender,eventArgs)
//Find Silverlight control in page
//"slControl" defined in the createObjectEx() function call
var slControl = document.getElementById('slControl');
//Find TextBlock XAML element
if (sender == "Canvas") _TB = slControl.Content.FindName("tbHello");
function MouseEnter(sender,eventArgs)
_TB.Text = "Mouse entered " + sender;
function MouseLeave(sender,eventArgs)
_TB.Text = "Mouse left " + sender;
function MouseClick(sender,eventArgs)
_TB.Text = sender + " clicked!";
Figure 11: Defining event handlers using JavaScript.
The root Canvas element defined in Figure 10 defines a Loaded event and routes it to a JavaScript function named ShowLoad. This function will be called after all the Canvas children have been loaded and are ready to be used. The Rectangle element defined in the XAML defines three events (MouseEnter, MouseLeave, and MouseLeftButtonDown) and routes them to their respective event handlers. The event handlers (refer to Figure 11) dynamically change the Text property of the TextBlock defined in the XAML.
Note that the sender of the event, as well as event arguments, are passed to each function, which is similar to event data passed to VB.NET and C# event handlers. Looking through the code in Figure 11 you ll notice that XAML elements such as the TextBlock shown in Figure 10 are located using a FindName function. While HTML DOM elements can still be located using the document.getElementById function, XAML elements that have a defined Name attribute are always located using the Silverlight FindName function.
Media, shapes, text, and more can also be animated and transformed using XAML elements combined with events and triggers. Animations provide a way to add rich interactivity into an application that would be difficult to achieve using only HTML, CSS, and JavaScript. Silverlight has a built-in animation engine that can perform many animation tasks.
Different types of animations are available, ranging from generic animations that target an XAML element property to more fine-grained animations that target elements based on key frames and times. Multiple articles could be written on the subject of animations, so I ll simply introduce them with an example that demonstrates how to move a TextBlock object.
Figure 12 shows an example of using the Storyboard and DoubleAnimation XAML elements to target a TextBlock element s Canvas.Left property and perform an animation. When the root Canvas loads, the Loaded event will be handled which triggers an animation story board to play. The story board contains a DoubleAnimation element that changes the TextBlock s Canvas.Left property from 80 to 200 over a period of 3 seconds. Once the value of 200 is reached, the animation reverses and goes the other way. This is handled automatically by setting the AutoReverse property to True.
Canvas.Left="36" Canvas.Top="80"
Foreground="Maroon" FontFamily="Verdana"
FontSize="24" FontWeight="Bold"
Text="Hello From Silverlight!">
Figure 12: Using the Storyboard and DoubleAnimation elements to animate text on a Silverlight canvas.
Learning to build Silverlight applications is a lot like learning to build HTML applications. Once you understand which XAML elements and attributes can be used, you can perform more easily the tasks you need. This article has introduced many of the key concepts needed to get started with building Silverlight applications. You ve seen the major players required to instantiate and embed a Silverlight control in a Web page. You ve also seen how a canvas can be defined, as well as different types of children (such as Rectangle, Ellipse, and TextBlock). Finally, you ve seen how XAML object events can be handled using JavaScript, and how animations can be used to move XAML objects around a canvas.
In future articles, I ll walk through the process of creating a more robust Silverlight application that can integrate with ASP.NET AJAX and Web services to display remote data in a simulated 3D environment. Until then, you can see an example of the application in Figure 13, or download the application s code from to get a sneak peek. A video walk-through of the application can also be viewed at

During shaft construction, water and soil inflow resulted in a sinkhole at the surface. Keller repaired the leak using jet grouting and densified the loosened soils with compaction grouting.
Faraday Launching Tunnel Shaft
A dry excavation after construction of the jet grout columns around the secant pile shaft’s outside diameter.
The project
The Carlsbad Desalination Plant was excavating a 55 foot deep, 18-foot diameter secant pile-supported shaft, installed by another contractor when soil and water leakage occurred due to insufficient pile overlap. The leakage resulted in a sinkhole opening near the perimeter of the shaft.
The challenge
The subgrade surrounding the shaft consisted of 25 feet of fill underlain by 25 feet of alluvium and the bedrock surface at a depth of 50 feet. The groundwater-surface was at a depth of about 27 feet. During the excavation of the shaft, soil and water leakage between the secant piles was encountered and a sinkhole adjacent to the shaft exterior occurred. Additionally, the project site was congested.
The solution
Keller performed compaction grouting to stabilize the sinkhole and jet grouting to restore the continuity of the shaft and seal the perimeter of the excavation stopping the soil and water seepage. Compaction grouting involves the injection of low-slump, low-mobility sand/cement grout to fill voids and stabilize loose soils through displacement. The purpose of the compaction grouting for this project was to stabilize the sinkhole conditions by filling possible subsurface voids and stabilizing the raveled soils.
Once the area was stabilized and made safe, Keller mobilized jet grouting equipment to the shaft. Jet grouting creates soil/cement (soilcrete) geometries in the ground by using high-velocity jets to erode and mix the in situ soil with cement grout. Keller performed jet grouting from a depth of 22 feet to 10 feet below the bedrock surface to construct soilcrete columns adjacent to the exterior of the shaft perimeter to seal any openings between the secant piles. Jet grouting below the bedrock surface targeted fractures or irregularities in the bedrock. Compact equipment was used to safely navigate the congested project site.

Military Ability
or, The Arts of Mars &c
Military ability (MA) is the numerical quantification of a character's ability to lead men in battle. MA is determined when a character is created by rolling one die, the result of which is that character's military ability. Military ability is occasionally determined for non-player characters, such as the Commander of a Regiment in which a character serves, since the MA of the non-player character will have a tremendous effect on the character.

CPR Adult 4
CPR Adult
Flash Card 4
If the victim does not respond, yell for help. This way an emergency unit is en route as you take the necessary steps to resuscitate the victim. If someone comes, have him phone 911 without hesitation and also have him retrieve the AED (automated external defibrillator). An AED is simple to use and can typically do three things: 1) Recognize the heart has stopped. 2) Tell the rescuer when a shock is needed (typically a simple press of a button) 3) Give a shock after the rescuer has properly placed the pads on the victim.
“Call 911!”
“Get the AED”
CPR Fact
An AED is easy to operate. It uses voice prompts to instruct the rescuer. Once the machine is turned on, the rescuer will be prompted to apply two electrodes provided with the AED to the victim’s chest. Once applied, the AED will begin to monitor the victim’s heart rhythm. If a “shockable” rhythm is detected, the machine will charge itself and instruct the rescuer to stand clear of the victim and to press the shock button (typically red in color).

Mars - Neptune - Moon/Lilith
GLOBAL FORECAST (14/01/2022 16:00 - 15/01/2022 06:00)
The celestial shape Tay square that is accomplished in the period described shows extremely strong disharmonious and overstraining cosmic energies. This geometric structure manifests itself when, viewed from the Earth's point of view in our cosmic system, connections are formed between four luminaries, planets or other important cosmic factors. The quadruple combination symbolizes the creation of some material base for the manifestation of the planetary energy.
In this celestial event between the planets there is the following relations: 90°-90°-180° or Mars (T) r Neptune (O) r Lilith (`) q Moon (W) w←.
The mentioned geometric figure is occurs relatively frequently in the Universe, and it shows that the Spiritual World chooses this form regularly to bring its ideas among us – humans.
Since this structure of aspects in the solar system possesses the quality of symmetry, this shows that the celestial energies have in themselves the potential through which to direct humans and other beings towards the world of the Truth.
In a global sense, The participation of the Moon in more complex cosmic connections means that they will be further enhanced, and the energy of the Universe will be directed also towards the wide public masses. The presence of Mars energy in a cosmic figure is most often a sign of dangerous, military, destructive processes, unfortunately, and even in the best case, it is a sign of the manifestation of the masculine principle in the world. Neptune's involvement brings a social emphasis on the configuration and even a mystical flavour into the cosmic situation; however, often Neptune enhances the influence of the Cosmos on water elements and vehement forces, and all phenomena associated with them.

What Is Hyperkinetic Muscle Activity?
Specialty. Neurology. Hyperkinesia refers to an increase in muscular activity that can result in excessive abnormal movements, excessive normal movements or a combination of both.
What is the most common hyperkinetic movement disorder?
Tics are the most common hyperkinetic disorder in children. Dystonia, stereotypies, choreoathetosis, tremors, and myoclonus also occur but are less common. Many hyperkinetic movement disorders manifest with multiple types of movements, which may include a combination of the various hyperkinesias.
What are some hyperkinetic conditions?
Hyperkinetic movement disorders include tremors, dystonia, chorea, tics, myoclonus, stereotypies, restless legs syndrome, and various other disorders with abnormal involuntary movements.
What are uncontrollable muscle movements?
Uncontrollable movements include many types of movements that you cannot control. They can affect the arms, legs, face, neck, or other parts of the body. Examples of uncontrollable movements are: Loss of muscle tone (flaccidity) Slow, twisting, or continued movements (chorea, athetosis, or dystonia)
What causes Hyperkinesia?
What is meant by hyperkinetic?
Since the prefix hyper- means “above, beyond”, hyperkinetic describes motion beyond the usual. The word is usually applied to children, and often describes the condition of almost uncontrollable activity or muscular movements called attention-deficit/hyperactivity disorder *(ADHD).
What is hyperkinetic gait?
Choreiform Gait (Hyperkinetic Gait) This gait is seen with certain basal ganglia disorders including Sydenham’s chorea, Huntington’s Disease and other forms of chorea, athetosis or dystonia. The patient will display irregular, jerky, involuntary movements in all extremities.

What causes Ballismus?
Ballismus is a severe movement disorder that is characterized by spontaneous involuntary movements, muscular weakness and incoordination of movements of the proximal extremities. It is mostly caused by neurodegenerative, vascular, toxic metabolic, infectious or immunological process affecting the basal ganglia.
How hyperkinetic conditions are related to physical activity?
People with these conditions have dangerous eating habits and often resort to excessive activity to expend calories for fat loss. Eating disorders that abuse exercise are considered hyperkinetic conditions.
What is hyperkinetic behavior?
A specific and common behavior disorder in children, the hyperkinetic syndrome, may be due to organic causes and is characterized by: hyperactivity; short attention span and poor powers of concentration; impulsiveness; irritability; explosiveness; variability; and poor school work.
What does it mean when your body randomly jumps?
What causes legs to jump involuntarily?
Dopamine is involved in controlling muscle movement and may be responsible for the involuntary leg movements associated with restless legs syndrome. In some cases, restless legs syndrome is caused by an underlying health condition, such as iron deficiency anaemia or kidney failure.
What is it called when you have uncontrollable movements?
Involuntary movements compose a group of uncontrolled movements that may manifest as a tremor, tic, myoclonic jerk, chorea, athetosis, dystonia or hemiballism. Recognition of involuntary movements associated with hyperkinetic movement disorders is an important diagnostic skill.
You might be interested: Question: Can Toddler Drink Too Much Water?
How is Hyperkinesis treated?
The most useful medication at present is the stimulant group of drugs, particularly dextroamphetamine and methylphenidate. Antipsychotic drugs are sometimes useful but carry the risk of depressing higher CNS functions such as attention and cognition.
What is the difference between Hyperkinesia and Hypertonia?
Hyperkinetic signs differ from hypertonia because hypertonia is appreciated only during movement imposed by the examiner (passive movement), whereas hyperkinetic movements are appreciated during movements made (voluntarily or involuntarily) by the child (active movement).
What are hypokinetic and hyperkinetic diseases?
Hyperkinetic movement disorders refer to dyskinesia, or excessive, often repetitive, involuntary movements that intrude upon the normal flow of motor activity. Hypokinetic movement disorders refer to akinesia (lack of movement), hypokinesia (reduced amplitude of movements), bradykinesia (slow movement), and rigidity.

Dust Separators
Dust Separators
Dust Separator Units
Our range of concrete and construction dust separators are designed to connect between your power tools, concrete floor grinder, scarifier, shotblaster or demolition equipment and vacuum to help capture the bulk of the dust before it gets through to the filters in your vacuum. Shop the range of dust separators including the popular 65L Supa Dust Separator to suit single-phase vacuums here.
Advantages of Using a Dust Separator
You can save time and money by adding a pre-separator to your single-stage dust collector. using this dust control equipment can save you time because emptying one of these is much easier than opening the lower, or "chip," bag of a bag-over-bag collector. It will save you money in the long run since the turbine will not be subjected to a constant onslaught of heavy chips or dangerous metal fragments such as the occasional screw or nail that falls to the floor. It will also allow your filter bags to perform what they were designed to do: filter dust rather than accumulate chips.
As the lower bag fills up, the filter surface area shrinks, and the filter bag's ability to filter efficiently diminishes. More blow-through with fewer filters and the same pressure. When a pre-separator is installed between the dust source and the collector, this happens at a considerably slower rate.
The heavy chips spin around the container's walls, losing momentum until they sink to the bottom, much like a cyclone dust separator. Lighter chips and dust are drawn up through the outlet port and caught by the filters in the dust collector.

FAQ: Does Coffee Make Gas?
Can drinking coffee cause gas?
Coffee can cause temporary bloating. Too, Dr. Roger Gebhard, M.D., gastroenterologist, states that coffee of any kind “can overexcite the digestive tract and may stimulate spasms in the bowel that cause bloating.” Luckily, bloating is temporary.
Is coffee good for gastric problem?
Why does coffee give me so much gas?
This increases blood sugar levels, which essentially are turned into fat, most commonly stored around your middle—this contributes heavily to bloating. Additionally, coffee can overexcite the digestive tract that can also lead to bloating.
Does coffee on an empty stomach cause gas?
Moreover, the consumption of coffee on an empty stomach will increase the level of acid in the stomach, which can lead to bloating and vomiting. Therefore, you should drink coffee an hour after waking up.
What stops gas naturally?
You can’t stop farting completely, but there are ways to reduce the amount of gas in your system.
1. Eat more slowly and mindfully.
2. Don’t chew gum.
3. Cut back on gas-producing foods.
4. Check for food intolerances with an elimination diet.
5. Avoid soda, beer, and other carbonated beverages.

Paleontology and Evolution
Both paleontology and evolution help us to understand each individual life of a species as a page in a book. In order to better understand the character of today’s species, and get hints at where they’re going, we can look at their ancestors. We get to see a dinosaur (for example), not as just a big skeleton, but can see the development of that dinosaur over time. Looking at a timeline of a species can help us glimpse eternity. The species doesn’t entirely die out but is passed on in other forms.
Through paleontology, we have discovered the T Rex evolved from smaller raptors known as Guanlong, Chinese for “crowned dragons”. Paleontogists have painstakingly gone over every bit of Guanlong’s remains to discover that the hips, distinctive T Rex teeth and fused nasal bones mean that they were the most likely ancestor of the mighty T Rex.
But keeping up such a massive body had its consequences. No one knows for sure what killed the dinosaurs off but some of their genes live on. Amazingly, T Rex genes have been found in chickens. That may be hard to believe until you’ve been chased across a barnyard by a cranky rooster.
The original theory of evolution had the creation of man as the “goal” of the evolutionary process, but this view has been heavily revised since Darwin’s day. Now, we can see that life exists for the purpose of just to exist. And the variety and ingenuity of life is awe inspiring.

Reflective Practice
Here I give some evidence of how I use reflective practice to receive feedback from students, peers, colleagues, and other faculty. This helps me develop my teaching and stay sharp.
[Figure 0]
My students do "muddiest points" so they have the opportunity to ask questions and let me know what aspects of the course are confusing to them. This is a great way to get feedback and responses from all students, especially those who are shy and prefer not to ask questions in front of their classmates. Muddiest points help me adjust my teaching and courses to make improvements.
[Figure 1]
I give my students (name optional) handouts with questions that prompt them to self-reflect and give feedback on the course and my instruction. Based on this information, I do my best to improve my courses and teaching. Moreover, such exercises aim to help students develop problem solving and metacognition by identifying personal learning barriers and evaluating their personal learning strategies, so perhaps they can adjust their own approach. For instance, students give me feedback on the in-class activities and identify the most challenging (or frustrating) parts of the course (see below).
My students also have the opportunity to pretend that they are the instructor of the course and suggest adjustments that they would make (see below). This is excellent feedback. If students say that some part of the course isn't helping their learning, then I do my best to make adjustments to accommodate their learning style. On the other hand, if students say that some part of the course is helpful to their learning, then I know to keep doing it.
[Figure 2]
In CS 121 I use Piazza to create polls so my students can vote on certain issues and give feedback that everyone can observe. For example, I use Piazza to vote on which in-class activities are most helpful to their learning (see below). From this, it became evident that most of my students feel that the in-class team activities (worksheets, short problems, whiteboard, etc.) and live coding demonstrations (we write the code together) are the most helpful, while none of them feel that the slides are the most helpful. Thus, I decided to adjust my teaching strategy by spending less in-class time doing slides and more in-class time doing team-activities and live coding demonstrations.
[Figure 3]
Occasionally I'll have colleagues observe my class and give me feedback so I can adjust my teaching (see below).
[Figure 4]
I've discovered that a Mid-Semester Assessment Protocals a.k.a. "MAP" can give useful feedback so I can adjust my teaching (see below).

It is postulated that a vigorous host inflammatory response in the cystic fibrosis lung contributes to lung injury. Tumour necrosis factor-alpha (TNF-alpha) may play a part in that process and in the generation of leukotrienes. Therefore, the relationships between sputum TNF-alpha, leukotriene concentration, and lung function abnormalities in 16 children with cystic fibrosis were investigated. Each subject provided sputum samples and performed spirometry. TNF-alpha was measured by enzyme linked immunosorbent assay; individual leukotrienes were separated using high performance liquid chromatography and quantified by radioimmunoassay. The geometric mean concentration of TNF-alpha was 129.7 pg/ml and 95% confidence interval 48.2 to 348.3. Mean (SEM) leukotriene B4 (LTB4) was 97.8 (22.9) pmol/g and total cysteinyl leukotrienes were 60.9 (14.8) pmol/g. Mean (SD) forced expiratory volume in one second (FEV1) of the group was 53 (15)% of predicted and forced vital capacity (FVC) was 65 (14)% of predicted. There was a significant positive correlation between TNF-alpha and both LTB4 and the total cysteinyl leukotriene sputum content. An inverse relationship existed between TNF-alpha and FEV1 and FVC. Moreover, a negative correlation was observed between sputum LTB4 and FEV1 and FVC. These results suggest that TNF-alpha and the leukotrienes may participate in the airways inflammation and airflow obstruction observed in cystic fibrosis subjects and support the hypothesis that TNF-alpha upregulates the 5-lipoxygenase pathway in vivo.

Graphene Flower Cloth
Graphene flower cloth is a three-dimensional composite material with densely formed Graphene on the surface of the carbon fiber.
Product description
Graphene is a material of great properties but is extremely thin with an important Van der Waals force which facilitate aggregation or mutual adhesion. For that reason when Graphene was processed for electrodes, maintaining the shape was challenging and making Graphene’s functionality last permanently was an issue. Our Graphene Flower Cloth is a brand new composite material in which Graphene is formed independently and three-dimensionally on the surface of carbon fibers. This carbon fiber can be processed into non-woven fabric or woven fabric. Graphene properties can be expressed permanently when applied to electrode members.
All the surface of the carbon fibers is covered by independently formed Graphene; this carbon fiber covered with Graphene can be used for woven or non-woven fabric structure of electrodes. A countless number of Graphene edges are distributed on the whole surface of the substrate.
1. Graphene is grown homogeneously on carbon fiber surface.
2. 3D structure with vertically-oriented graphene edges on carbon fiber.
3. Can be formed from various carbon fiber materials such as woven-cloth,non-woven cloth.
4. Graphene layers are rigidly fixed on carbon fiber surface leading to effective graphene functions.
5. Best used as field emission electrode, bio-fuel cell electrode, super capacitor electrode, catalyst for chemical reaction and base materials.

Free Template Tuesday #4 – Tumult Hype “Heart”
Heart Template ThumbnailThis Sunday is Saint Valentine’s Day. That usually means lots of romance, lots of flowers, lots of chocolates and lots of hearts. If you’re in the middle of creating interactive content for Valentine’s Day, you might be wondering how to make a heart. Currently, Hype doesn’t have drawing tools or concave shapes. But by using basic elements, a Heart can be created in Hype. By stacking basic shapes, elements can be overlapped to create a heart.
The first step is to create two circles and one square. They should all be the same size. The width of the elements should be equal to the height of the elements. In the example, the elements are 100×100 pixels. The square is rotated 45° so that it looks like a diamond shape. By default, Hype’s “Rectangle” and “Ellipse” elements have a 1-pixel border. It is removed to create a seamless overlap.
By simply sliding the elements together, they can make a perfect heart. Hype makes it easy with elements that “snap” to each other. Once positioned together, these elements can be grouped. That allows for easily moving or rotating the three elements.
This is better than just importing a picture of a heart, such as a PNG or SVG, as the hit area is perfect. The heart can be used as a button. Simply set the three elements to the same action. Although, there are some caveats with this technique. While this approach can work well for launching Hyperlinks, it is not suited for mouseover / mouseout effects. The three shapes won’t be synchronized to hover events. While the mouse might be hovering over one or two of the “Heart” elements, a third element is outside of that action.
The “Group” itself can have an action assigned to it, but the shape of the group won’t match the shape of the contained elements. That means the heart might not be ideal for Physics based animation. The collision shape of the group is not heart shaped. It’s either rectangular or rounded with chamfered edges. But if the heart isn’t moved by Physics, then the three “heart” elements can be “Static” Physics elements. Other elements can bounce off the three ungrouped “Heart” elements.
The “Heart” Hype Template is a workaround to the current limitations in Hype. However, there is potential. Hype uses “matter.js” as the Physics engine. That supports Concave SVG Paths.
Version 0.9.0 of Matter.js was launched last month. Technology moves fast. If Tumult adds an SVG editor and more Matter.js features to Hype, there could be another way to create a heart. That’s what’s interesting about web development. There are many ways to solve a problem. The correct answer depends on your project. By combining shapes in this manner, you might be able to solve problems in other Hype projects.

The effortless ease with which we move masks a profound complexity. While we can now build a car that can drive autonomously for thousands of miles and rival the performance of a human driver, we still cannot build a robot that can get into that car with the grace of even a 6-year old child.
Nearly every movement a person makes represents a decision, where the individual must weigh the costs and rewards of each movement and use this as a basis upon which they choose among competing movements and learn to make new ones. Our goal is to gain fundamental knowledge about the subjective costs and rewards underlying movement decision making and to apply this understanding towards the development of rehabilitation therapies for individuals with movement disorders such as Parkinson’s Disease. We use a novel neuroeconomic approach that combines concepts and tools from engineering, neuroscience, psychology, and economics to better understand why we move in the ways we do and how we learn to move in new ones. This framework of movement neuroeconomics is advantageous because it allows for the quantification of the subjective costs and rewards and the identification of the neural mechanisms underlying movement decision making. Moreover, it provides us with a common language with which to compare decision making across populations and decision-making domains (i.e., movement, economic and social decision making).
Experiments use a combination of approaches involving virtual reality, robotic interfaces, kinetic and kinematic analyses. Coupled with computational models, these investigations will provide greater insight into the interplay between the biomechanical and sensorimotor processes underlying human movement control and decision-making. Projects in the lab investigate:
1. The role of effort and reward in decision making and movement control
2. Risk-sensitivity in movement control and adaptation
3. The role of metabolic cost in motor learning
4. Effect of age and coactivation on movement control
5. Motor control and learning in Parkinson's Disease and Multiple Sclerosis
6. Dynamics learning and generalization for postural control
7. Using the Wii Balance Board for teaching biomechanics
8. Optimal Foraging in movements

One vaccine injection could carry many doses
Long-term delivery
The molecular weight of the PLGA polymer and the structure of the polymer molecules’ “backbone” determine how fast the particles will degrade after injection. The degradation rate determines when the drug will be released.
By injecting many particles that degrade at different rates, the researchers can generate a strong burst of drug or vaccine at predetermined time points. “In the developing world, that might be the difference between not getting vaccinated and receiving all of your vaccines in one shot,” said Dr Kevin McHugh.
They then tested particles filled with ovalbumin, a protein found in egg whites that are commonly used to experimentally stimulate an immune response.
“The SEAL technique could provide a new platform that can create nearly any tiny, fillable object with nearly any material, which could provide unprecedented opportunities in manufacturing in medicine and other areas,” said Prof Langer. These particles could also be useful for delivering drugs that have to be given on a regular basis, such as allergy shots, to minimize the number of injections.
Sealed cups
Prof Langer’s lab began working on the new drug delivery particles as a way to deliver multiple doses of a vaccine over a specified period of time with just one injection. That could allow babies in developing nations, who might not see a doctor very often, to get one injection after birth that would deliver all the vaccines they would need during the first one or two years of life.
PLGA can also be designed to degrade at different rates, allowing for the fabrication of multiple particles that release their contents at different times.
Using photolithography, they created silicon moulds for the cups and the lids. Large arrays of about 2,000 moulds are fit onto a glass slide, and these moulds are used to shape the PLGA cups and lids. Once the array of polymer cups has been formed, the researchers employed a custom-built, automated dispensing system to fill each cup with a drug or vaccine. After the cups are filled, the lids are aligned and lowered onto each cup, and the system is heated slightly until the cup and lid fuse together, sealing the drug inside.
“Each layer is first fabricated on its own, and then they’re assembled together,” said Dr Jaklenec. “Part of the novelty is really in how we align and seal the layers. In doing so we developed a new method that can make structures which current 3-D printing methods cannot. This new method called SEAL (StampEd Assembly of polymer Layers) can be used with any thermoplastic material and allows for fabrication of microstructures with complex geometries that could have broad applications, including injectable pulsatile drug delivery, pH sensors, and 3-D microfluidic devices.”

What is the difference between a god and a Titan?
In short, they are all deities, but different generations of deities. The word ” Titan ” is used to denote a class of mythological entities that existed before “Gods” were born and Titans are usually used to describe the creation of the world.
What did the Titans do in Greek mythology?
The Titans were the previous generation, and family of gods, whom the Olympians had to overthrow, and banish from the upper world, in order to become the ruling pantheon of Greek gods.
Who are the Titan gods?
THE TITANES ( Titans ) were six elder gods named Kronos (Cronus), Koios (Coeus), Krios (Crius), Iapetos (Iapetus), Hyperion and Okeanos (Oceanus), sons of Ouranos (Uranus, Sky) and Gaia (Gaea, Earth), who ruled the cosmos before the Olympians came to power.
Where did the Titans come from Greek mythology?
The Titans were the deities in Greek mythology that preceded the Olympians. They were the children of the primordial deities Uranus (heaven) and Gaea (earth). The Titans included Oceanus, Tethys, Hyperion, Theia, Coeus, Phoebe, Cronus, Rhea, Mnemosyne, Themis, Crius and Iapetus.
You might be interested: Often asked: What Are The Roman Numina Greek Mythology?
Can Titans kill gods?
Titans, like Gods, are immortal. This not only means that they do not age, but also that they cannot be killed. While some fade in power and into obscurity, others are punished eternally with various tortures (see: Prometheus).
Who is stronger Titans or gods?
The truth is that the Titans are more powerful then the gods. The only reason the Titans lost to the gods was because Zeus promised many of the exiled and imprisoned giants freedom if they would fight on the side of the gods.
Were Titans good or bad?
MISCONCEPTION #4: THE TITANS WERE EVIL. So the Titans are deities in Greek mythology who proceeded the 12 Olympians. Nowadays they’re often portrayed as bad guys, like in the Percy Jackson and the Olympians series, but in the original depictions they had human qualities, both good and bad, just like the other gods.
Who was the youngest Titan?
In Greek mythology Cronus was the son of Uranus (Heaven) and Gaea (Earth), being the youngest of the 12 Titans.
Did Titans ever exist?
Titan, in Greek mythology, any of the children of Uranus (Heaven) and Gaea (Earth) and their descendants. According to Hesiod’s Theogony, there were 12 original Titans: the brothers Oceanus, Coeus, Crius, Hyperion, Iapetus, and Cronus and the sisters Thea, Rhea, Themis, Mnemosyne, Phoebe, and Tethys.
Why did Zeus eat his wife?

Why did the gods kill the Titans?
Who was the smiling Titan?
Dina’s Pure Titan was very tall and, like most regular Pure Titans, resembled a male human. Its main distinguishing feature was its characteristic smile, in which its lips are fixed wide open, exposing its teeth and gums at all times.
Is Medusa a Titan?
Medusa is referred to as a Titan by the Stygian Witches. Medusa was never considered a Titan in the myths; the Stygian witches may have spoken metaphorically.
Who is the strongest Titan in Greek mythology?
11. Cronus: Titan Ruler of the Universe. Although he was the youngest son of Gaea and Uranus, Cronus was also the strongest of the Greek Titans.
Are Titans humans?
All Titans were originally humans of a race of people called the Subjects of Ymir. Ymir Fritz was the first Titan, who became one after merging with a strange spine-like creature in a tree. The Founding Titan could personally turn Subjects of Ymir into Titans.

Stroke is treatable
Want create site? Find Free WordPress Themes and plugins.
By: Dr. Bhuvaneshwari Rajendran
Strokes are brain attacks. They occur when the blood supply to the brain becomes blocked or when there is a bleed inside the brain. 85% of the strokes are due to blocked blood vessels. A stroke is a medical emergency that needs immediate medical attention. Because during a stroke, the brain does not receive enough oxygen or nutrients, causing brain cells to die, Strokes need to be diagnosed and treated as quickly as possible to minimize brain damage. Treatment depends on the type of stroke.
Ischemic (block) and hemorrhagic (Bleed) strokes have different causes; both require different forms of treatment
Ischemic strokes are caused by arteries being blocked or narrowed, treatment for this starts with drugs that break down clots and prevent others from forming. TPA (Tissue Plasminogen Activator) is also very effective at dissolving clots but needs to be injected within 4.5 hours of stroke symptoms starting.
There are other procedures that can be carried out to decrease the risk of strokes or TIAs. A carotid endarterectomy involves a surgeon opening the carotid artery and removing any plaque that might be blocking it.
Hemorrhagic stroke are caused by blood leaking into the brain, so treatment focuses on controlling the bleeding and reducing the pressure on the brain. Treatment can begin with drugs given to reduce the pressure in the brain, control overall blood pressure, prevent seizures and prevent sudden constrictions of blood vessels. If an individual is taking blood-thinning medication like aspirin, we need to stop. Surgery can be used to repair any problems with blood vessels if identified in the right patients.
After a stroke, successful recovery will often involve specific therapies and support, such as: Speech therapy, Physical therapy, Occupational Therapy and Support from Friends and Family. With the right assistance and the support of loved ones, rehabilitation to a normal quality of life is possible, depending on the severity of the stroke.
The best way to prevent a stroke can be achieved through lifestyle changes, including – eating a healthy diet and maintaining a healthy weight, exercising regularly, no smoking, avoiding alcohol or drinking moderately, keeping blood pressure under control, managing diabetes, treating obstructive sleep apnea which can be an independent cause for strokes. Doctor can also help to reduce the risk of future ischemic strokes through prescribing blood thinner medication
Transient ischemic attack (TIA) is different from the types above because the flow of blood to the brain is only briefly interrupted. TIAs are similar to ischemic strokes in that they are often caused by blood clots or other clots. They should be regarded as medical emergencies, even if the blockage of the artery and its symptoms are temporary. They serve as warning signs for future strokes and indicate that there is a partially blocked artery or clot source in the heart.
Studies show evidence that over a third of people who experience a TIA have a major stroke within a year if they have not received any treatment. Between 10 and 15 percent of people will have a major stroke within 3 months of a TIA. So please seek medical help as soon as possible to prevent major strokes.
Signs of strokes are – If there is a loss of Balance, there is a blurring of vision or loss of vision, if the person tries to smile, does one side of the face droop, if the person tries to raise both his arms, does one arm drift downward?, and if the person tries to repeat a simple phrase, is their speech slurred or strange?
Stroke is treatable, recognise symptoms early and seek medical help as soon as possible. The faster a person with suspected stroke receives medical attention, the better their prognosis will be, and the less likely they will be to experience permanent damage or death.

Hurtado v. California
From Justice Harlan's Mouth To The Warren Court's Ears
The lone dissenter to the Court's majority ruling was Justice Harlan. In his view, if the right to a grand jury had not been a "fundamental" component of due process, it would not have been guaranteed by the Fifth Amendment. Certain rights, including the right to a grand jury, "were of a character so essential to the safety of the people" that they had been specifically written into "the early Amendments of the Constitution . . . " Harlan, as a minority of one, did not prevail. Instead, the majority decision meant that the Court spent much of the next few decades hammering out its notions of due process, by means of ruling on various cases.
In 1953, Earl Warren became the Supreme Court chief justice. Under his leadership, virtually every right guaranteed by both the Fifth and the Sixth Amendments was incorporated into the legal understanding of due process: the right to counsel, the right against self-incrimination, the right of the accused to confront his or her accuser, the right to a speedy trial, the right to trial by jury, and the right to protection against double jeopardy (being tried or punished twice for the same crime).
Many legal commentators saw the decisions of the Warren Court as a departure from the Court's previous cautious approach to establishing rights. However, some commentators have had the opposite reaction. They see the so-called activism of the Warren Court as returning to the traditional understanding of rights, the one that existed before Hurtado. In that view, Hurtado was the departure, the case in which, for the first time, the U.S. Supreme Court ignored the traditional English common law provisions spelled out in the Bill of Rights in favor of the possibilities of "progress and improvement."

A native app is a software program created specifically for an operating system platform. Because a native app is designed specifically for a device and its operating system, it may take advantage of device-specific hardware or software. Compared to internet apps or mobile cloud apps created to be generic across different devices, native apps can improve speed and benefit from new techs, such as GPS.
Native apps are considered best for providing a fantastic user experience because of their quick performance. The aesthetics align with the platform’s UX, enhancing the user experience, however, because they must simultaneously develop native programs for two platforms.
Entrepreneurs are concerned about the increasing cost of native app development.
Apple and Google offer their own set of development tools, UI components, and SDKs to app developers. Many businesses will engage in native mobile app development as it provides numerous advantages compared to other apps such as hybrid or web. Because businesses are overly dependent on mobile software, they must be aware of the advantages and disadvantages of various app development methods.
Platforms And Native Applications
The term “native app” refers to software that runs on devices such as Mac and PC, with examples including the Photos, Mail, and Contacts apps that includes pre-installed and configured on every Apple machine. In the case of mobile web applications, however, the phrase “native app” refers to any software designed to run on a particular device platform.
The most well-known mobile operating systems are iOS and Android. Native apps are created in the same code used to create the device and its operating system. For example, iOS applications are developed in Objective-C or Swift, but Android-native apps are written in Java.
Native apps interact with the device’s operating system in a way that enables them to speed up and more freely than other kinds of applications. Developers generate unique app versions for each device type if the app is advertised to consumers of multiple device types.
For instance, the Facebook app was initially designed in HTML5 because the same code could be used on iOS, Android, and the mobile web. Regrettably, the app had been slower for iOS users, prompting Facebook’s app programmers to make separate code for the iOS platform. Complicated activities can be restructured, such as communication in the backend of the original thread or application that controls the UI.
Native apps can access many features on a smartphone, such as a mic, accelerometer, and app notifications, due to their ability to connect to resources. Navigation programs like Waze, networking apps like Twitter, and games like Pokémon Go are all examples of native applications.
For the maximum possible consumer experience, Pokémon Go effectively utilizes the system’s functionality, such as GPS for tracking locations, the camera for virtual reality, and the sensor for maximum speed. Notifications made to deliver gamers right back into the game over time can also be used with Pokémon Go.
A native app can be downloaded and installed directly on a smartphone. The native app’s data remains locally on the phone or externally, such as in cloud storage.
Pros Of Native App Development
Native applications provide the following benefits:
• Comprehensive functionality as a result of utilizing the essential device’s characteristics;
• Software speed that is quick and responsive.
• Notice through push.
• A user interface that is more in line with the OS’s user experiences; and
• Evaluations in mobile apps provide quality control.
Cons Of Native App Development
• Each device has its version of the software; there are many codebases.
• The cost of hiring more programmers to help create and maintain a program code for every platform.
• In each feature upgrade, time was invested on several builds for different platforms.
Native apps vs. Web apps
A web app is a network-based app that the customer uses using a web browser rather than downloading. Google Chrome, Safari, and Mozilla Firefox are some examples of web browsers. Web apps, such as Safari on an iPhone, enable capabilities ranging from banking access to the account to YouTube video streaming.
While native apps are customized to a particular device, most online apps may be developed in JavaScript, CSS, and the primary form of HTML for cross-browser compatibility. Because web apps are not designed for a specific device, they can use a single code. Web apps like blog is quick and easy to create, but they lack the versatility and speed of native apps.
Native vs. Hybrid apps
A hybrid application is a blend of native and online apps. A hybrid app’s internal workings are comparable to a web app, yet it installs like native software. Internal device APIs are available to hybrid apps, able to access the camera, storage, and GPS. Hybrid apps include Yelp and Instagram, for example.
HTML and CSS are used to create hybrid apps. Developers start with a single code base and then modify it to fit every system. With a hybrid app, fewer programmers are focused on every platform than fully native software. Hybrid apps use a container or WebView, a browser enclosed within a mobile app, to execute a web app.
Hybrid apps differ from native apps in several ways. Hybrid apps are similar to web apps in that they share the same navigating components. A hybrid program also has no offline option; it requires an internet connection to function. Native apps, on the other hand, can be used offline.
The difference in price between native and hybrid apps is negligible. Designers must write the code for both sorts of applications for them to run on various platforms. Generally, if an app’s development period is less than four to six months, a hybrid app is better because it can be built quickly.
Tools For Native Applications
Swift and Java are open-source software languages that Apple and Google employ extensively.
Xamarin is a cross-platform software design tool that may be used to create native apps for iOS and Android, other platforms that employ the C# programming language.

NASA Preparing to Drill for Moon Water
NASA has officially confirmed the presence of water on the light side of the Moon and is now working on mapping out just how much water is available and how to access it.
NASA Preparing to Drill for Moon Water
Using the Stratospheric Observatory for Infrared Astronomy (SOFIA), scientists detected water molecule wavelengths in a massive crater on the Moon’s southern hemisphere. Results published in the October 2020 issue of Nature Astronomy suggest that a cubic meter of lunar soil could be holding around 100-412 parts per million (approx. 12 ounces) of water.
“We had indications that H2O, the familiar water we know, might be present on the sunlit side of the Moon,” said Paul Hertz, Director of NASA’s Astrophysics Division in the Science Mission Directorate, in a press release. “Now we know it is there.”
But what do these findings mean for the future of space travel? Discovering water on the Moon is somewhat akin to discovering oil on Earth. A valuable and useable resource right there where we need it (without the need for transport from Earth) could cut the cost of space exploration significantly.
A water-coated Moon essentially becomes an orbital gas station. When water molecules are broken up into oxygen and hydrogen, cooled to liquid form, and funneled into a rocket together, an exothermic reaction generates extreme heat and energy for powerful propulsion.
In addition, a single astronaut needs around 100 gallons of water per day for drinking, cooking, and bathing. Currently, it costs around $8.35 million (around $10,000 per pound) for a rocket to carry 100 gallons of water from Earth into orbit – plus an additional amount to put it on the Moon.
NASA is working to cut the cost of transporting water to just $1,000 per pound, but it’s still a steep tab. Discovering water on the lunar surface itself is therefore incredibly valuable for Moon exploration and human habitation.
Interestingly, the observation that these molecules exist in sunlight is novel. Most observations of water-like molecules on the Moon are made along the poles and in shadowed areas that are never exposed to sunlight – areas that would be more difficult to mine. But SOFIA found water molecules in Clavius Crater on the sunlit side of the Moon.
Previously, scientists thought water would evaporate in sunlit areas that can reach 120oC during the day. But Casey Honniball, NASA Goddard Space Flight Center Postdoctoral Program Fellow and head author of the Nature Astronomy paper, suggests that the water molecules are stable here because they exist in a “trapped” state.
“Without a thick atmosphere, water on the sunlit lunar surface should just be lost to space,” said Honniball. “Yet somehow we’re seeing it. Something is generating the water, and something must be trapping it there.”
“We believe the water is being stored inside the micro meteorite impact glass beads, and these would shelter the water from being lost to space or migrating to the lunar pole,” Honniball said. “And this would mean that without a lunar atmosphere the water could stay on the surface of the Moon.”
How did the water get there? Scientists suggest it may be the result of micrometeorites carrying water and impacting the lunar surface. In addition, oxygen in the lunar soil could be reacting with hydrogen from solar winds and radiation from micrometeorite collisions.
We still don’t know exactly how much water may be present on the Moon, where or how deep the water is, and how difficult it would be to extract. But the recent discovery has made lunar mining a hot topic among aerospace and drilling companies alike.
In preparation for the upcoming Artemis mission, NASA has chosen the Houston-based company Intuitive Machines to deliver a massive lunar drill to help harvest Moon ice. The Polar Resources Ice Mining Experiment (PRIME-1) drill is scheduled to arrive on the Moon by December 2022.
NASA plans to follow up by launching its Volatiles Investigating Polar Exploration Rover (VIPER) in late 2023 to create maps of Moon water resources and learn more about accessibility.
“The VIPER mission will give us surface-level detail of where the water is and how much is available for us to use, says NASA’s project overview. “This will bring us a significant step closer towards NASA’s ultimate goal of a sustainable, long-term presence on the Moon – making it possible to eventually explore Mars and beyond.”

Neither Masculine nor Feminine: Using the Neuter Gender in Spanish
Neuter usually refers to concepts or ideas, not concrete things
Dominican Republic bathrooms to illustrate lesson on the neuter gender in Spanish
Lo mejor del parque es el baño. (The best part of the park is the bathroom.). Daniel Lobo/Creative Commons.
Not quite. True, Spanish isn't like German, where in terms of gender nouns fall into three classifications (masculine, feminine, and neuter). Indeed, in Spanish, nouns are either masculine or feminine. But Spanish does have use for the neuter form, which can come in handy when referring to concepts or ideas.
Lo as the Neuter Definite Article
Chances are that you're familiar with el and la, which usually are translated as "the" in English. Those words are known as definite articles because they refer to definite things or people (el libro, for example, refers to a specific book). Spanish also has a neuter definite article, lo, but you can't use it before a noun like you do el or la because there are no neuter nouns.
A sample sentence should help make this easier to understand: Lo importante es amar. Here importante is the adjective (generally in the masculine singular when used with lo) functioning as a noun. You could use a variety of English translations: "The important thing is to love." "What is important is to love." "The important aspect is to love."
Here are some other sample sentences with possible translations:
• Lo mejor es el baño. (The best part is the bathroom. The best thing is the bathroom.)
• Lo nuevo es que estudia. (What's new is that he's studying. The new thing is that he studies.)
• Me gusta lo francés. (I like French things. I like what is French.)
• Le di lo inútil a mi hermana. (I gave the useless stuff to my sister. I gave the useless items to my sister. I gave what was useless to my sister. Note that you couldn't use lo útil for a specific object that has a name. If were referring to a useless spoon, for example, you could say la inútil because the word for "spoon," cuchara, is feminine. )
• Puedes pintar lo tuyo. (You can paint what's yours. You can paint your things.)
• Me enojó lo tarde que salió. (It angered me how late he left. The lateness of his leaving angered me.)
Lo as a Neuter Direct Object
• No lo creo. (I don't believe it.)
• Lo sé. (I know it.)
• No lo comprendo. (I don't understand it.)
• No puedo creerlo. (I can't believe it.)
Neuter Demonstrative Pronouns
Usually, demonstrative pronouns are used to point at an object: éste (this one), ése (that one), and aquél (that one over there). The neuter equivalents (esto, eso, and aquello) are all unaccented, end in -o, and have roughly the same meanings, but as is the case with the direct object lo, they usually refer to an idea or concept rather than an object or person. They can also refer to an unknown object. Here are some examples of its use:
• No olvides esto. (Don't forget this.)
• No creo eso. (I don't believe that.0
• ¿Qué es aquello? (What is that over there?)
• ¿Te gustó eso? (Did you like that?)
• No me importa esto. (This isn't important to me.)
Ello is the neuter equivalent of él and ella. Its use these days is unusual, and only in literature are you likely to find it used as the subject of a sentence. It usually is translated as "it" or "this." Note that in these examples, ello refers to an unnamed situation rather than a specified thing.
• Hemos aprendido a vivir con ello. (We have learned to live with it.)
• Por ello no pudo encontrar la trascendencia que hubiera deseado. (Because of it, he couldn't find the transcendence he had wanted.)

Linear organization of a sentence in the short stories of Grigorije Božović
Institute for Serbian Culture, Leposavić
Material and spiritual culture of Kosovo and Metohija (MESTD - 178028)
Keywords: sentence; sentence structure; linear organization; Grigorije Božović
The corpus studied is divided into three parts, referring to the sentence structures with the post-unit, inter-unit and pre-unit elements. In addition to these elements, which together with the basic ones form sentence sequence thus representing a context - internal or external, in the structures with the post-unit elements, there are syntax items that predominately refer to the predicate core of the sentence. In the pre-unit elements structures, when they are in the initial position, there are items related to the subject, while in the inter-unit elements of sentences, there are constructions related to both constitutive sentence parts, although in the separate structure, examples in which the construction in the inter-unit elements sentence structure refers to the predicate are more numerous. The insight into the linear organization of the sentence would not be complete if its communication value were not included in the analysis. From all above mentioned, it is evident that a predicate, as a functional pivot and the highest point of the tone line of the statement, can be moved and freed from some added elements, depending on what and in which way we want to demonstrate it. Therefore, the way in which sentence parts are arranged, allows the formation of different sentence perspectives.

James Webb Space Telescope unfurls massive sunshield in major deployment milestone –
One of the James Webb Space Telescope’s most nail-biting deployment steps is safely in the books.
The $10 billion observatory unfurled its huge sunshield on Friday (Dec. 31), carefully unfolding the five-layer structure by sequentially deploying two booms.
“Shine bright like a diamond. With the successful deployment of our right sunshield mid-boom, or ‘arm,’ Webb’s sunshield has now taken on its diamond shape in space,” mission team members said via Webb’s Twitter account Friday night.

The sunshield is one of the most crucial and complicated features of Webb, which launched on Dec. 25 to seek out faint heat signals from the early universe. Detecting such signals requires that Webb keep its instruments and optics extremely cold, and the sunshield will help it do just that by reflecting and radiating away solar energy.
The shiny silver shield measures 69.5 feet long by 46.5 feet wide (21.2 by 14.2 meters) when fully deployed — far too large to fit inside the protective payload fairing of any currently operational rocket. So it was designed to launch in a highly compact configuration and then unfold once Webb got to space.
That deployment is an elaborate, multistep process with many different potential failure points that could sink the entire mission.
“Webb’s sunshield assembly includes 140 release mechanisms, approximately 70 hinge assemblies, eight deployment motors, bearings, springs, gears, about 400 pulleys and 90 cables totaling 1,312 feet [400 m],” Webb spacecraft systems engineer Krystal Puga, who works at Northrop Grumman, the prime contractor for the mission, said in a video about Webb’s deployments that NASA posted in October.
Sunshield deployment began on Tuesday (Dec. 28) when Webb lowered the two pallets that hold the five-layer structure. Additional steps followed over the next few days. On Thursday (Dec. 30), for example, the observatory released the cover that had protected the sunshield during its time on Earth and launch to space.
That cover complicated Friday’s activities a bit: The Webb team delayed boom deployment by a few hours to make sure that the cover had fully rolled up as planned, and as needed.
“Switches that should have indicated that the cover rolled up did not trigger when they were supposed to,” Patrick Lynch, deputy chief of the communications office at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, wrote in a blog post Friday
“However, secondary and tertiary sources offered confirmation that it had,” Lynch added. “Temperature data seemed to show that the sunshield cover unrolled to block sunlight from a sensor, and gyroscope sensors indicated motion consistent with the sunshield cover release devices being activated.”
Webb team members initiated deployment of the port (lefthand) mid-boom at 1:30 p.m. EST (1830 GMT) on Friday, Lynch wrote, and the activity wrapped up at 4:49 p.m. EST (2149 GMT). Extension of the starboard mid-boom began at 6:31 p.m. EST (2331 GMT) and was done by around 10:13 p.m. EST (0313 GMT on Jan. 1), Lynch wrote in another blog post.

Unfurling the sunshield is a huge milestone, so Webb team members are likely breathing big sighs of relief after Friday’s success. But the sunshield work isn’t done yet; its five thin Kapton layers must still be brought up to the proper tension, which the mission team aims to do over the weekend.
After that’s done, the focus will shift to deploying Webb’s secondary mirror and its 21.3-foot-wide (6.5 m) primary mirror. Those tasks are expected to be complete by Jan. 7 at the earliest, but deployment timelines are flexible, so don’t be shocked (or concerned) if that target isn’t met.
Locking the mirrors into their proper place will bring Webb’s complex main deployment phase to an end. The next major milestone to follow will be an engine burn, scheduled for 29 days after launch, that will insert Webb into orbit around its final destination: the Sun-Earth Lagrange Point 2 (L2), a gravitationally stable spot 930,000 miles (1.5 million kilometers) from our planet.
Webb team members will still have a lot of work to do after the observatory arrives at L2. They’ll have to precisely align the 18 segments of Webb’s primary mirror so the pieces work together as a single light-collecting surface, for example, and check out and calibrate the telescope’s four scientific instruments.
Regular science operations are expected to start six months after launch, in the summer of 2022. For at least five years after that, Webb will study some of the universe’s first stars and galaxies, hunt for intriguing compounds in the atmospheres of nearby exoplanets and make a variety of other potentially transformative cosmic observations.

Here’s why whales don’t drown when they gulp down food underwater — ScienceDaily – newsconcerns
Ever wondered whether whales can burp, and why they don’t drown when they gulp down gallons of water and krill? New UBC research may just hold the answer.
Researchers found that lunge-feeding whales have an ‘oral plug’, a fleshy bulb in their mouths that moves backwards to seal off the upper airways during feeding, while their larynx closes to block the lower airways.
This plug prevents water from entering their lungs when they feed, according to a paper published today in Current Biology. “It’s kind of like when a human’s uvula moves backwards to block our nasal passages, and our windpipe closes up while swallowing food,” says lead author Dr. Kelsey Gil, a postdoctoral researcher in the department of zoology.
Lunge-feeding whales eat by, you guessed it, lunging at their prey, accelerating at high speed and opening their mouths to engulf water and krill. Sometimes this amount can be larger than their own bodies, says Dr. Gil, an impressive feat given this group includes the humpback and the blue whale, the largest animal on Earth. Water is then drained via their baleen, leaving the tiny, tasty krill behind to be swallowed.
The researchers investigated fin whales specifically, a type of lunge-feeding whale and found the ‘oral plug’ needed to move in order to allow food to pass to the esophagus. The only way it could was towards the back of the head, and up, blocking off the nasal passages when the whale swallows. Simultaneously, cartilage closes at the entrance to the larynx, and the laryngeal sac moves upwards to block off the lower airways, says Dr. Gil. “We haven’t seen this protective mechanism in any other animals, or in the literature. A lot of our knowledge about whales and dolphins comes from toothed whales, which have completely separated respiratory tracts, so similar assumptions have been made about lunge-feeding whales.”
It turns out humans have a similar system to swallow food without getting anything in their lungs: we have the epiglottis and soft palate, a ‘lid’ of cartilage and a flap of muscle in our throat and mouth, respectively. Humans could probably eat underwater as well, says Dr. Gil, but it would be rather like swimming at high speed towards a hamburger and opening your mouth wide as you approached — difficult not to flood your lungs.
The whales’ oral plug and closing larynx is central to how lunge-feeding evolved, a key component in the enormous size of these creatures, the researchers say. “Bulk filter-feeding on krill swarms is highly efficient and the only way to provide the massive amount of energy needed to support such large body size. This would not be possible without the special anatomical features we have described,” says senior author Dr. Robert Shadwick, a professor in the UBC department of zoology.
Investigating whale anatomy often involves trying to dissect whales that have died from stranding which comes with such challenges as trying to complete work before the tide rises. However, for this research, Dr. Gil and her colleagues dissected whales in Iceland in 2018, recovering tissue that wasn’t being used for food from a commercial whaling station. Working with whales in real-time would be wonderful, she says, but might require some advancements in technology. “It would be interesting to throw a tiny camera down a whale’s mouth while it was feeding to see what’s happening, but we’d need to make sure it was safe to eat and biodegradable.”
The team will continue to explore the mechanisms related to the pharynx, and of the small esophagus that is responsible for rapidly transporting hundreds of kilograms of krill to the stomach in less than a minute. With the many human impacts that disrupt food chains, and knowing how whales feed and how much they eat, it’s good to know as much as possible about these animals in order to protect them and their eco systems, says Dr. Gil.
And there’s plenty more to find out, including whether whales cough, hiccup, and yes, burp. “Humpback whales blow bubbles out of their mouth, but we aren’t exactly sure where the air is from — it might make more sense, and be safer, for whales to burp out of their blowholes.”

The drifting giant A68 iceberg released billions of tons of fresh water in South Georgia ecosystem – MercoPress
Saturday, January 22nd 2022 – 10:56 UTC
Full article

Scientists monitoring the giant A68a iceberg from space reveal that a huge amount of freshwater was released as it melted around the sub-Antarctic island of South Georgia. An estimated 152 billion tons of freshwater – equivalent to 20 x Loch Ness or 61 million Olympic sized swimming pools, entered the seas around the sub-Antarctic island of South Georgia when A68a melted over three months in 2020/2021, according to a new study published this month by the British Antarctic Survey.
In July 2017, A68a calved off the Larsen-C Ice Shelf on the Antarctic Peninsula and began its epic three-and-a-half year, 4.000 km journey across the Southern Ocean. At 5719 square kilometers – about a quarter the size of Wales – it was the biggest iceberg on Earth when it formed and the sixth largest on record. Around Christmas 2020, the berg received widespread attention as it drifted worryingly close to South Georgia, raising concerns it could harm the island’s fragile ecosystem.
A team from Center for Polar Observation and Modeling and BAS used satellite measurements to chart the iceberg’s area and thickness change throughout its life cycle. The authors show that the iceberg had melted enough as it drifted to avoid damaging the sea floor around South Georgia by running aground. However, a side effect of the melting was the release of a colossal 152 billion tons of fresh water in close proximity to the island – a disturbance that could have a profound impact on the island’s marine habitat.
For the first two years of its life, A68a stayed close to Antarctica in the cold waters of the Weddell Sea and experienced little in the way of melting. However, once it began its northwards journey across the Drake Passage it traveled through increasingly warm waters and began to melt. Altogether, the iceberg thinned by 67 meters from its initial 235 m thickness, with the rate of melting rising sharply as the berg drifted around South Georgia.
Laura Gerrish, GIS and mapping specialist at BAS and co-author of the study said, “A68 was an absolutely fascinating iceberg to track all the way from its creation to its end. Frequent measurements allowed us to follow every move and break-up of the berg as it moved slowly northwards through an area called ‘iceberg alley’, a route in the ocean which icebergs often follow, and into the Scotia Sea where it then gained speed and approached the island of South Georgia very closely.”
If an iceberg’s keel is too deep it can become grounded on the sea floor. This can be disruptive in several different ways; the scour marks can destroy fauna, and the berg itself can block ocean currents and predator foraging routes. All of these potential outcomes were feared when A68a approached South Georgia. However, this new study reveals that it collided only briefly with the sea floor and broke apart shortly afterwards, making it less of a risk in terms of blockage. By the time it reached the shallow waters around South Georgia, the iceberg’s keel had reduced to 141 meters below the ocean surface, shallow enough to avoid the seabed which is around 150 meters deep.
Nevertheless, the ecosystem and wildlife around South Georgia will certainly have felt the impact of the colossal iceberg’s visit. When icebergs detach from ice shelves, they drift with the ocean currents and wind while releasing cold fresh melt-water and nutrients as they melt. This process influences the local ocean circulation and fosters biological production around the iceberg. At its peak, the iceberg was melting at a rate of 7 meters per month, and in total it released a staggering 152 billion tons of fresh water and nutrients.
“This is a huge amount of melt water, and the next thing we want to learn is whether it had a positive or negative impact on the ecosystem around South Georgia. Because A68a took a common route across the Drake Passage, we hope to learn more about icebergs taking a similar trajectory, and how they influence the polar oceans,” said Anne Braakmann-Folgmann, a researcher at CPOM and PhD candidate at the University of Leeds’ School of Earth and Environment, and lead author of the study.
The journey of A68a has been charted using observations from five different satellites. The iceberg’s area change was recorded using a combination of Sentinel-1, Sentinel-3, and MODIS imagery. Meanwhile, the iceberg’s thickness change was measured using CryoSat-2 and ICESat-2 altimetry. By combining these measurements, the iceberg’s area, thickness, and volume change were determined.
Tommaso Parrinello, CryoSat Mission Manager at the European Space Agency pointed out that “Our ability to study every move of the iceberg in such detail is thanks to advances in satellite techniques and the use of a variety of measurements. Imaging satellites record the location and shape of the iceberg and data from altimetry missions add a third dimension as they measure the height of surfaces underneath the satellites and can therefore observe how an iceberg melts.”

Are the northern lights caused by 'particles from the Sun'? Not exactly –
Credit: PhotoVisions/Shutterstock
What a spectacle a big aurora is, its shimmering curtains and colorful rays of light illuminating a dark sky. Many people refer to aurora as the northern lights (the aurora borealis), but there are southern lights too (the aurora australis). Either way, if you’re lucky enough to catch a glimpse of this phenomenon, it’s something you won’t soon forget.
The is often explained simply as “particles from the Sun” hitting our atmosphere. But that’s not technically accurate except in a few limited cases. So what does happen to create this natural marvel?
We see the aurora when energetic charged particles—electrons and sometimes ions—collide with atoms in the upper atmosphere. While the aurora often follows explosive events on the Sun, it’s not quite true to say these energetic particles that cause the aurora come from the Sun.
Earth’s magnetism, the force that directs the compass needle, dominates the motions of electrically charged particles in space around Earth. The magnetic field near the surface of Earth is normally steady, but its strength and direction fluctuate when there are displays of the aurora. These fluctuations are caused by what’s called a magnetic substorm—a rapid disturbance in the in near-Earth space.
To understand what happens to trigger a substorm, we first need to learn about . Plasma is a gas in which a significant number of the atoms have been broken into ions and electrons. The gas of the uppermost regions of Earth’s atmosphere is in the , as is the gas that makes up the Sun and other stars. A gas of plasma flows away continuously from the Sun: this is called the solar wind.
Plasma behaves differently from those gases we meet in everyday life. Wave a magnet around in your kitchen and nothing much happens. The air of the kitchen consists overwhelmingly of electrically neutral atoms, so it’s quite undisturbed by the moving magnet. In a plasma, however, with its electrically charged particles, things are different. So if your house was filled with plasma, waving a magnet around would make the air move.
When solar wind plasma arrives at the earth it interacts with the planet’s magnetic field (as illustrated below—the magnetic field is represented by the lines that look a bit like a spider). Most of the time, plasma travels easily along the lines of the magnetic field, but not across them. This means that solar wind arriving at Earth is diverted around the planet and kept away from the Earth’s atmosphere. In turn, the solar wind drags the field lines out into the elongated form seen on the night side, called the magnetotail.
Sometimes moving plasma brings magnetic fields from different regions together, causing a local breakdown in the pattern of magnetic field lines. This phenomenon, called magnetic reconnection, heralds a new magnetic configuration, and, importantly, unleashes a huge amount of energy.
These events happen fairly often in the Sun’s outer atmosphere, causing an explosive energy release and pushing clouds of magnetized gas, called coronal mass ejections, away from the Sun (as seen in the image above).
If a arrives at Earth it can in turn trigger reconnection in the magnetotail, releasing energy that drives electrical currents in near-Earth space: the substorm. Strong electric fields that develop in this process accelerate electrons to high energies. Some of these electrons may have come from the , allowed into near-Earth space by reconnection, but their acceleration in the substorm is essential to their role in the aurora.
These particles are then funneled by the magnetic towards the atmosphere high above the polar regions. There they collide with the oxygen and nitrogen atoms, exciting them to glow as the aurora.
Now you know exactly what causes the northern lights, how do you optimize your chances of seeing it? Seek out dark skies far from cities and towns. The further north you can go the better but you don’t need to be in the Arctic Circle. We see them from time to time in Scotland, and they’ve even been spotted in the north of England—although they’re still better seen at higher latitudes.
Websites such as AuroraWatch UK can tell you when it’s worth heading outside. And remember that while events on the Sun can give us a few days warning, these are indicative, not foolproof. Perhaps part of the magic lies in the fact that you need a little bit of luck to see the aurora in all its glory.

• Discuss the fundamental difference between anaerobic cellular respiration and fermentation
In aerobic respiration, the final electron acceptor is an oxygen molecule, O2. If aerobic respiration occurs, then ATP will be produced using the energy of high-energy electrons carried by NADH or FADH2 to the electron transport chain. If aerobic respiration does not occur, NADH must be reoxidized to NAD+ for reuse as an electron carrier for the glycolytic pathway to continue. How is this done? Some living systems use an organic molecule as the final electron acceptor. Processes that use an organic molecule to regenerate NAD+ from NADH are collectively referred to as fermentation. In contrast, some living systems use an inorganic molecule as a final electron acceptor. Both methods are called anaerobic cellular respiration, in which organisms convert energy for their use in the absence of oxygen.
Anaerobic Cellular Respiration
Certain prokaryotes, including some species in the domains Bacteria and Archaea, use anaerobic respiration. For example, a group of archaeans called methanogens reduces carbon dioxide to methane to oxidize NADH. These microorganisms are found in soil and in the digestive tracts of ruminants, such as cows and sheep. Similarly, sulfate-reducing bacteria, most of which are anaerobic (Figure), reduce sulfate to hydrogen sulfide to regenerate NAD+ from NADH.
This photo shows a bloom of green bacteria in water.
The green color seen in these coastal waters is from an eruption of hydrogen sulfide–producing bacteria. These anaerobic, sulfate-reducing bacteria release hydrogen sulfide gas as they decompose algae in the water.

Lactic Acid Fermentation
The fermentation method used by animals and certain bacteria, such as those in yogurt, is lactic acid fermentation (Figure). This type of fermentation is used routinely in mammalian red blood cells, which do not have mitochondria, and in skeletal muscle that has an insufficient oxygen supply to allow aerobic respiration to continue (that is, in muscles used to the point of fatigue). In muscles, lactic acid accumulation must be removed by the blood circulation, and when the lactic acid loses a hydrogen, the resulting lactate is brought to the liver for further metabolism. The chemical reactions of lactic acid fermentation are the following:
Pyruvic acid + NADH lactic acid + NAD +
Art Connection
This illustration shows that during glycolysis, glucose is broken down into two pyruvate molecules and, in the process, two NADH are formed from NAD^{+}. During lactic acid fermentation, the two pyruvate molecules are converted into lactate, and NADH is recycled back into NAD^{+}.
Tremetol, a metabolic poison found in the white snakeroot plant, prevents the metabolism of lactate. When cows eat this plant, tremetol is concentrated in the milk they produce. Humans who consume the milk can become seriously ill. Symptoms of this disease, which include vomiting, abdominal pain, and tremors, become worse after exercise. Why do you think this is the case?
Alcohol Fermentation
Another familiar fermentation process is alcohol fermentation (Figure), which produces ethanol. The first chemical reaction of alcohol fermentation is the following (CO2 does not participate in the second reaction):
pyruvic acid + H + CO 2 + acetaldehyde + NADH + H + ethanol + NAD +
The first reaction is catalyzed by pyruvate decarboxylase, a cytoplasmic enzyme, with a coenzyme of thiamine pyrophosphate (TPP, derived from vitamin B1 and also called thiamine). A carboxyl group is removed from pyruvic acid, releasing carbon dioxide as a gas. The loss of carbon dioxide reduces the size of the molecule by one carbon, producing acetaldehyde. The second reaction is catalyzed by alcohol dehydrogenase to oxidize NADH to NAD+ and reduce acetaldehyde to ethanol. The fermentation of pyruvic acid by yeast produces the ethanol found in alcoholic beverages. Ethanol tolerance of yeast is variable, ranging from about 5 percent to 21 percent, depending on the yeast strain and environmental conditions.
This photo shows large cylindrical fermentation tanks stacked one on top of the other.
Other Types of Fermentation
Other fermentation methods take place in bacteria. We should note that many prokaryotes are facultatively anaerobic. This means that they can switch between aerobic respiration and fermentation, depending on the availability of free oxygen. Certain prokaryotes, such as Clostridia, are obligate anaerobes. Obligate anaerobes live and grow in the absence of molecular oxygen. Oxygen is a poison to these microorganisms and kills them on exposure. We should also note that all forms of fermentation, except lactic acid fermentation, produce gas. The production of particular types of gas is used as an indicator of the fermentation of specific carbohydrates, which plays a role in the laboratory identification of the bacteria. Various methods of fermentation are used by assorted organisms to ensure an adequate supply of NAD+ for the sixth step in glycolysis. Without these pathways, this step would not occur, and ATP could not be harvested from the breakdown of glucose.
Section Summary
If NADH cannot be oxidized through aerobic respiration, another electron acceptor is used. Most organisms will use some form of fermentation to accomplish the regeneration of NAD+, ensuring the continuation of glycolysis. The regeneration of NAD+ in fermentation is not accompanied by ATP production; therefore, the potential of NADH to produce ATP using an electron transport chain is not utilized.
Art Connections

Review Questions
Which of the following fermentation methods can occur in animal skeletal muscles?
1. lactic acid fermentation
2. alcohol fermentation
3. mixed acid fermentation
4. propionic fermentation
Free Response
What is the primary difference between fermentation and anaerobic respiration?
Fermentation uses glycolysis only. Anaerobic respiration uses all three parts of cellular respiration, including the parts in the mitochondria like the citric acid cycle and electron transport; it also uses a different final electron acceptor instead of oxygen gas.

Inca Dove Facts
Inca dove facts are great for families to read together
Inca doves have been associated with travelers following them to find water as these birds are known for flying directly towards water. They can be identified as a small dove with a long and squared tail. This species is known to have a scaly appearance and each wing holds a surprise of bright rufus-colored primaries which can be seen when they take flight. An Inca dove is famous for taking direct flight using a rapid beating of their wings and they are scattered around southern America and most of Mexico.
These birds play a very important role in the ecosystem because of their dispersal of seeds and eating habits. They are found in areas with human settlements and scattered trees within the geographical boundaries they live in. Even though their name is inspired by the Inca empire, these birds are not found in the areas which were once a part of this historical empire.

Inca Dove Interesting Facts
What type of animal is an Inca dove?
An Inca dove is a bird belonging to the Columbidae family which generally consists of doves and pigeons.
What class of animal does an Inca dove belong to?
The Inca dove belongs to the class of Aves belonging to the kingdom of Animalia.
How many Inca dove are there in the world?
The total reported population of these doves is around two million. However, All About Birds Resource reports that the breeding members of this species total at about three million out of which 61% belong to Mexico and 33% are found in the United States.
Where does an Inca dove live?
This species can be seen all over the southwest of the United States and northern Central America. However, they are gradually increasing their range both north and south thanks to adaptations which allow them to live near human settlements. They can be found throughout the Sonoran Desert region near human settlements.
What is an Inca dove's habitat?
These birds seem to enjoy living in arid or semi-arid open areas with scattered trees and shrubs. They are also found around human settlements such as farmlands, gardens and parks. They look for trees that appeal to them and build a nest that is approximately 5-20 ft (152-609 cm) high. This nest is built using stems, leaves, grass, and twigs.
Who do Inca doves live with?
These birds are mostly found living in pairs or small flocks, however, they are very sensitive to the cold. In the winter, they engage in behavior such as rooting close to several other members of its species and forming a pyramid to keep each other warm. They exhibit this behavior in sites sheltered from the cold by huddling with each other using their wings. These doves are monogamous birds, living with their partner and hatchlings in their nest high above the ground.
How long does an Inca dove live?
The lifespan of these birds can range between two to eight years, however, they are reported to survive up to about three years of age in the wild like other species of this family.
How do they reproduce?
During courting, a male struts and makes 'coos' to a female while bobbing its head. Males fan their tail feathers while keeping their tail vertical to show off their markings. These birds are known for breeding and building nests all year round. A male assumes the responsibility of finding leaves and twigs while females build the nest. They lay two eggs inside their nest which is above ground and 12 to 14 days after incubation, the young are fed 'pigeon milk' like other similar species.
What is their conservation status?
These birds are classified as Least Concern on the IUCN Red List with their range and numbers increasing every year. They currently do not require conservation, however, some of them have been experiencing habitat loss due to human and natural factors.
Inca Dove Fun Facts
What do Inca doves look like?
An Inca dove is known to be a small, brownish-gray in color bird with a scaly appearance. Their tail is long and slender, having white sides with a gray center bordered by black. They can easily be identified by their tail, black bills, pink legs, and feet.
Inca doves are extremely cute.
How cute are they?
An Inca dove is generally considered to be a very dull and scaly bird by most people but for many bird lovers, it is a very cute and lovable bird. A lot of Inca dove lovers are fans of its beautiful tail feathers. Inca dove hatchlings are very cute as well, exhibiting rust-brown feathers on their wings.
How do they communicate?
These doves are known for using the 'coo' sound to communicate. They are also known for using their heads to communicate such as bobbing their head during mating.
How big is an Inca dove?
Inca doves are about 7.1-9.1 in (18-23 cm) in length with their wingspan reaching up to 12.5 in (32 cm) long. They are very small doves and are half the size of a mourning dove but are observed to be larger than a common ground dove.
How fast can an Inca dove fly ?
These doves can reach speeds of up to 28 mph (45 kph) during flight. They are not as fast as larger birds but are quite well-paced in terms of their small size. They are known for taking a direct flight from the ground by using rapid beats of their wings.
How much does an Inca dove weigh?
An Inca dove can weigh anything from 1.1-2.0 oz (30-58 g). They are one of the lighter species of doves.
What are their male and female names of the species?
Males and females of this species do not have a specific name to differentiate between the two. They are merely referred to as a male Inca dove and a female Inca dove.
What would you call a baby Inca dove?
A baby Inca dove is called an 'Inca dove hatchling' or a 'young Inca dove' as there are no specified names for baby doves.
What do they eat?
Inca doves are known for being herbivores or granivores as they mainly eat grains, seeds, and fruits. Due to some seeds being hard to digest, these doves have been reported to swallow grit. Upon hatching, they are fed pigeon milk, a whitish fluid that both the parents store. This species goes crazy foraging on the ground for seeds in light vegetation and use their bills to dig the dirt around to uncover seeds.
Are they dangerous?
Inca doves are not violent towards humans but similar to that of other birds of similar species, these birds can infect domestic turkeys with Chlamydia psittaci.
Would they make a good pet?
There are not a lot of instances of this bird being kept as a pet, however, there are many reports of these birds being social and calm pets.
Did you know...
During winter, these birds conserve heat by roosting in pyramid-like formations which can consist of up to 12 birds in communal huddles.
The ‘coo’ sound, specifically made by these species, can be translated as 'no hope'.
An Inca dove is able to lower its body temperature to protecting itself from the cold during the night and during winter.
Do Inca doves migrate?
These birds are classified as resident birds but this species is expanding its range both northward and southward.
Why are Inca doves disappearing?
Even though they are increasing their range and their numbers are not dwindling, they are found in fewer places and habitats. Inca doves, alongside other species of doves, have been losing their habitats in certain places and disappearing due to active urbanization which has a converse effect on the habitat of these birds as compared to cultivated lands and smaller settlements. Alongside this, repeated droughts and heatwaves take a toll on young doves and this is adversely affecting their living conditions while changing their distribution status and habitats.

Why is the molar enthalpy of vaporization of a substance larger than its molar enthalpy of fusion (at constant pressure); for example, in the case of ice and water.
You are watching: Why is latent heat of vaporization greater than fusion
Enthalpies of phase changes are fundamentally connected to the electrostatic potential energies between molecules. The first thing you need to know is:
There is an attractive force between all molecules at long(ish) distances, and a repelling force at short distances.
If you make a graph of potential energy vs. distance between two molecules, it will look something like this:
Here the y-axis represents electrostatic potential energy, the x-axis is radial separation (distance between the centers), and the spheres are "molecules."
Since this is a potential energy curve, you can imagine the system as if it were the surface of the earth, and gravity was the potential. In other words, the white molecule "wants" to roll down the valley until it sits next to the gray molecule. If it were any closer than just touching, it would have to climb up another very steep hill. If you try to pull them away, again you have to climb a hill (although it isn"t as tall or steep). The result is that unless there is enough kinetic energy for the molecules to move apart, they tend to stick together.
Now, the potential energy function between any two types of molecules will be different, but it will always have the same basic shape. What will change is the "steepness," width, and depth of the valley (or "potential energy well"), and the slope of the infinitely long "hill" to the right of the well.
Since we are talking about relative enthalpies of fusion and vaporization for a given system, we don"t have to worry about how this changes for different molecules. We just have to think about what it means to vaporize or melt something, in the context of the spatial separation or relativity of molecules, and how that relates to the shape of this surface.
First let"s think about what happens when you add heat to a system of molecules (positive enthalpy change). Heat is a transfer of thermal energy between a hot substance and a cold one. It is defined by a change in temperature, which means that when you add heat to something, its temperature increases (this might be common sense, but in thermodynamics it is important to be very specific). The main thing we need to know about this is:
Temperature is a measure of the average kinetic energy of all molecules in a system
In other words, as the temperature increases, the average kinetic energy (the speed) of the molecules increases.
Let"s go back to the potential energy diagram between two molecules. You know that energy is conserved, and so ignoring losses due to friction (there won"t be any for molecules) the potential energy that can be gained by a particle is equal to the kinetic energy it started with. In other words, if the particle is at the bottom of the well and has no kinetic energy, it is not going anywhere:
If it literally has no kinetic energy, we are at absolute zero, and this is an ideal crystal (a solid). Real substances in the real world always have some thermal energy, so the molecules are always sort of "wiggling" around at the bottom of their potential energy wells, even in a solid material.
The question is, how much kinetic energy do you need to melt the material?
In a liquid, molecules are free to move but stay close together
This means you need enough energy to let the molecules climb up the well at least a little bit, so that they can slide around each other.
If we draw a "liquid" line approximating how much energy that would take, it might look something like this:
The red line shows the average kinetic energy needed for the particles to pull apart just a little - enough that they can "slide" around each other - but not so much that there is any significant space between them. The height of this line compared to the bottom of the well (times Avogadro"s number) is the enthalpy of fusion.
What if we want to vaporize the substance?
In a gas, the molecules are free to move and are very far apart
As the kinetic energy increases, eventually there is enough that the molecules can actually fly apart (their radial separation can approach infinity). That line might look something like this:
I have drawn the line a little bit shy of the "zero" point - where the average molecule would get to infinite distance - because kinetic energies follow a statistical distribution, which means that some are higher than average, some are lower, and right around this point is where enough molecules would be able to vaporize that we would call it a phase transition. Depending on the particular substance, the line might be higher or lower.
In any case, the height of this line compared to the bottom of the well (times Avogadro"s number) is the enthalpy of vaporization.
See more: Solving For A Reactant In A Solution, Solving For A Reactant In Solution
As you can see, it"s a lot higher up. The reason is that for melting, the molecules just need enough energy to "slide" around each other, while for vaporization, they need enough energy to completely escape the well. This means that the enthalpy of vaporization is always going to be higher than the enthalpy of fusion.

Besides facts and concepts, your school should also teach the basic methods used by scientists in their work. This is essential. Some ways to look at the world are at the heart of the scientific undertaking. Students must learn these techniques to understand subjects such as physics, biology, and astronomy. It is not easy to describe (or teach) scientific inquiry. There is no fixed routine or set of steps that will lead a researcher to the response he seeks. However, there are certain characteristics of science that distinguish it from other methods of investigation. It will be useful to talk about some of the ways in which scientists think, work and see the universe so that you can see if your child’s school teaches this. Scientists as an ordered place approach the universe. They do not regard it as random, but as regular and predictable in a broad sense. The earth turns once every 24 hours. The tide is coming in, and the tide is coming out. Scientists want to recognize these regularities and then identify the general principles that explain them. That is, they try to achieve a systematic understanding that tells us how things work and why. Good...

The crucial R rate in the South West has risen slightly since last week.
The Government's scientific advisory group (SAGE) confirmed the figure for the region now stands at 0.8 to 1.1, with the true figure expected to be towards the middle of that region.
It has slightly increased from 0.8 to 1.0 from the previous week.
The R number is a measure of how many people on average each infected person transmits the virus to.
The Government have put an asterisk against several regions, including the South West, representing that the number of low cases means that estimates are ‘insufficiently robust to inform policy decisions.
Other regions which have seen slight increases in the R number are the North West, London and the South East.
The growth rate, which reflects how quickly the number of infections are changing day by day, also shows that Covid-19 could be growing in our region.
It has risen from minus five per cent and plus one percent to minus one per cent and plus two per cent.
In Gloucestershire there have been 63 lab-confirmed positive Covid-19 tests between August 1 and 19, with the highest amount of confirmed cases on any single day standing at eight, on August 6.
According to the latest Government data, there have been 1,948 confirmed tests since the start of the pandemic in Gloucestershire.
What does the 'R' number mean?
The document states: "An R number of 1 means that on average every person who is infected will infect 1 other person, meaning the total number of new infections is stable.
The R number is estimated from data such as hospital admissions, ICU admissions and deaths, as well as contact pattern surveys and swabs from households.

Sitharam, India
Affectionately known as Swamiji, he hails from a small village called Peeparkhedi in the district of Dhamtari in Chhattisgarh. When he was a young man, he joined Nyogi of the Chhattisgarh Mukti Morcha as a train union activist for about ten years. After that, he helped organize beedi workers. He joined Ekta Parishad in 1988 and was the organization’s first president. His main work on land rights was with the Kawar and Bhunja tribes living around Gariband.
Swami ji tells a story about how the mining contractors did not like him helping the tribal communities and they tried to poison him. He made a narrow escape. “I’m deeply moved by the Adivasis, and the satyagraha movements led by Ekta Parishad.” Swamiji has been in all the satyagrahas of Ekta Parishad, modeling the values of Gandhi. With all his hard working recent years he became the President of Prayog.

How Cairo can help ease the Israeli-Palestinian crisis
Gulf governments were understandably emotional about the violence taking place at al-Aqsa as well. Yet their public stance on the matter became more objective and nuanced once Iranian-backed Hamas started firing rockets at Israel. For example, Anwar Gargash, an advisor to Emirati president Sheikh Khalifa bin Zayed, issued a tweet condemning militants for “exploiting the suffering of the Palestinian people for narrow and unworthy calculations,” while influential religious figures such as Waseem Yousef criticized Hamas for using civilians as human shields.

What are Instruction Formats?
Computer ArchitectureComputer ScienceNetwork
Instruction includes a set of operation codes and operands that manage with the operation codes. Instruction format supports the design of bits in an instruction. It contains fields including opcode, operands, and addressing mode.
The instruction length is generally preserved in multiples of the character length, which is 8 bits. When the instruction length is permanent, several bits are assigned to opcode, operands, and addressing modes.
The function of allocating bits in the instruction can be interpreted by considering the following elements −
• Number of addressing modes
• Number of operands
• Number of CPU registers
• Number of register sets
• Number of address lines
The figure displayed the general IA-32 (Intel Architecture- 32 bits) instruction format. IA-32 is the instruction format that can Intel’s most outstanding microprocessors. This instruction format includes four fields, such as opcode field, addressing mode field, displacement field, and immediate field.
The opcode field has 1 or 2 bytes. The addressing mode field also includes 1 or 2 bytes. In the addressing mode field, an instruction needs only one byte if it uses only one register to generate the effective address of an operand.
The field that directly follows the addressing mode field is the displacement field. If an effective address for a memory operand is computed using the displacement value, then it uses either one or four bytes to encode. If an operand is an immediate value, then it is located in the immediate field and it appears either one or four bytes.

The Christmas feast has its roots from before the Middle Ages, but it’s during the Victorian period that the dinner we now associate with Christmas began to take shape.
Roast turkey also has its beginnings in Victorian Britain, previously other forms of roasted meat such as beef and goose were the centerpiece of the Christmas dinner.
The turkey was added to this by the more affluent sections of society in the 19th century, but its perfect size for a middle class family gathering meant it became the dominant dish by the beginning of the 20th century.

Curious Physics – Problem Solving
Expect the unexpected, predict the unpredictable. Physics is the science which helps us to understand everything around us, from the tiniest particles through to the infinite (or not) Universe.
Isaac BucketsFundamentally, physicists are problem solvers! When presented with a puzzle, we use the skills we have practised to solve a huge variety of problems, from building more efficient solar panels to solve the world's energy crisis, to the latest mobile devices that use up some of that energy. Being an expert problem solver allows us to approach curious problems and explain the unexpected or predict the unpredictable.
In our talk, we will demonstrate to you how by simply applying Physics you already know from school, you can solve some seemingly crazy problems. For example, this “gravity-defying” table, the Mould Effect ( ), when a string of beads seems to jump out of a glass, and the Magnus Effect ( ) - the Physics that David Beckham used to “bend it like Beckham”.
Being able to explain these questions by applying your physics knowledge isn’t always easy. However, it becomes easier the more problems you solve, and to become an expert problem solver takes practice. It is a bit like training for a marathon, do a little bit of training every day and you will succeed. Do a little bit of problem-solving every day, and you will be able to explain these amazing effects! ( ) is here to help! We have thousands of FREE physics problems of varying difficulties to take you from your GCSE all the way through to university. Working on these problems will help you on your journey to mastering physics. Work through our standard problems first and then have a go at our extraordinary problems on rainbows, tennis or chain fountains.
Remember that, as with any training, some days will be harder than others, it is OK to get the answer wrong the first time around (in fact we actually encourage it). All physicists get things wrong, making mistakes is how big discoveries are made and Nobel prizes won. The more you put into physics, the more surprises and rewards it will give in return.
Physics is real, relevant and remarkable!
Isaac Homepage
Practice your problem solving skills by answering A Misbehaving Student ( ) on A good way to start looking at all Physics problems is to:
1. Look at the problem and find the goal of the problem: Will the student break the table?
2. Draw a diagram of the situation: in this case, you will want to draw the forces acting on each object; the table top, the student, and the table legs. And don’t forget to label ALL the forces on your diagram!
3. Identify the relevant physics concepts and useful equations, and what we can neglect: Is the table in equilibrium? Do Newton’s laws of gravity apply? Do we need to consider Hooke’s Law? Do we need to consider moments?
4. Work out the solution: work logically through the problem writing down each step, otherwise it is very easy to make mistakes. Even the most experienced physicists do!
5. Now check your working: do the units match? Does the result seem reasonable? What would happen if the student were 100 kg?
6. Correct? Sit back and enjoy the satisfaction of having solved a problem!

Advantages of central heating systems
Heating and cooling is an absolute necessity in regions like Melbourne where there are bitter cold winters and hot summers. According to the Energy Users Association of Australia, up to 40% of household bills come from heating and air conditioning needs annually. So, choosing an efficient heating option is crucial for Melbourne homeowners to help keep comfortable while also saving energy.
Of all the heating options, central heating systems are considered one of the most efficient options available for both homes and businesses. Central heating systems distribute heat evenly from a central heat source to different rooms in your home or office through a network of ducts or pipe. There are several heat sources that provide heat to the system, including heat pumps, wood/gas/diesel boiler, electric resistance, solar heating, biomass system, etc.
Choosing an efficient system that best suits your home’s needs is crucial and hence you should weigh your options. The economical way of central heating systems wins if you are looking for comfort, efficiency and savings. Here are some key advantages of choosing central heating systems
With central heating systems, you will have only one central heat source, which you can choose from many including heat pumps, gas, electric energy, solar panels, biomass system, etc. Instead of using several heaters for individual rooms, a central system can be used to efficiently heat your home and save energy.
Central Location
Central heating systems deliver heats from one central location to each of your room through a well-insulated network of ducts or pipes. This allows your whole interior to be heated simultaneously, and quickly. It is also safer because it has only one heat source that can help avoid damage from happening in your entire house.
You can also use different thermostat controls for individual rooms regarding the required heat needs. If heat is not required in one room you can turn it off, making it easier to regulate temperature and save energy. A thermostat control also helps shut down your system automatically, when the desired or programmed temperature is reached.
Although the initial installation of a central heating system can be a costly endeavour, it can work for you recovering the cost in the long run. A regularly maintained and programmed heating system can run efficiently, allowing energy cost to go down.
If you reside in Melbourne area and want your heating system inspected and maintained to help run with efficiency, and prolong its lifespan, contact us today and let our qualified team at Melbourne, service and maintain your system thoroughly and offer you quality services.

What are the pros and cons of the traditional retirement income method?
Questions & Answers | 0 comments
Now that everyone is living longer, methods for retirement have gone through some significant changes. Wealth Management expert Michael Meskin explains what the current trends are in the United States. Retirement is no longer a certain occurrence but rather it is now a period or stage in one’s life with many different options for how to deal with the financial aspects of the transition.
An individual’s retirement goal is to guarantee a steady income during their post-working years. To accomplish this goal, individuals are often advised to invest in diverse assets that generate enough cash flow to cover expenses. For many, this typically includes an employer-sponsored pension, Social Security, and withdrawals from savings. The traditional retirement income method can be defined as a combination of an employer-sponsored pension, Social Security, and withdrawals from savings.
In the retirement age, those who have been working for a living can consider generating retirement income from a variety of sources. For those who want a steady, reliable source of income, a traditional retirement income method might be a good fit, but there are a number of pros and cons to consider before making this decision.

Welcome to Dungeons and Dragons: Basic Description Part One
Welcome to Dungeons and Dragons: Basic Description Part One
Ollie Pearson and Abigail McDowell
Dungeons and Dragons (D&D) is a role-playing game (RPG) that takes place in the fictional world of the Forgotten Realms.
D&D has two types of players: The first type is the Dungeon Master who controls the world and all NPCs (non-player characters).
The other type is Players, who control one character which they make, with the occasional player also playing as a Familiar (Pet) that accompanies the Player.
Players are mainly two things: a race and a class. The race is otherwise known as a species, for example: humans, elves, or trolls. The class is the job or role the character has, such as: ranger, paladin, soldier, or wizard. Characters are made by filling out a character sheet.
Each character has their own stats. Stats include Strength(STR), Constitution(CON), Dexterity(DEX), Wisdom(WIS), Charisma(CHA), and Intelligence(INT). Each is a different part of a character. Strength is the muscle in a character like how much damage you can do with an unarmed strike. Constitution is the endurance of a character and it can and increases hit points can increase your health. Dexterity is your agileness or quickness like your reaction speed. Wisdom is similar to your willpower or how wise you are. Charisma is how much you are likable or how easy it is to convince someone. Intelligence is your bookish knowledge also wizards can cast spells with stat.
In response to the question “Do you like D&D ?” 7th grader Sydney Burns says, “I really enjoy Dungeons and dragons. It was a good way to learn something new. I really enjoy role-playing and this was a good way to practice it with friends.”
And to the question “How did you learn about D&D?” she says, ” I learned about D&D through Lizzie(The Editor of the newspaper) and then started playing it because of a 5th teacher at my elementary school, Mr. Varela.”
Finally, to the question “What was your first character?” she said, “I played a ranger-shifter named Mabel.”
As you can see D&D is a complicated game. This story is going to be part of a series on how to play D&D how to make a character and how to become a D&D pro!

What is Check
Check in Dictionary
What is Check?
check is a document of a bank nature that has, specified, a written order of payment, by which the holder of a bank account, also called a drawer, enables another person, known as a beneficiary, to collect a certain amount of money in the bank, or drawer, where the former has its funds. The word comes from the English check or check, which derives from the verb “ to check ”, and which means ‘to verify’.
The primary function of the check is to serve as a means of payment, since, as such, under commercial law, the check is a title of value that gives its holder the literal, autonomous and legitimate right that said document reflects.
Check and its characteristics
The characteristics of a check to trust its validity must be, in general, the following: contain an explicit mention of the type of document that is (in this case, a check), name and address of the bank, date and place of issue, payment order for a specified amount of money, name and signature of the drawer or account holder’s own or autograph hand, and full name of the beneficiary. Some banks, in addition, to avoid fraud and counterfeiting, assign a number to their checks as internal control.
Types of Check
There are different types of checks, including:
• Bearer check: one that is paid directly to the person who carries it, without any other requirement.
• Nominal check: unlike the bearer check, the name of the person authorized to collect it is specified in the nominal check.
• Blank check: one that is delivered to the beneficiary without specifying the amount of money to be cashed.
• Cross check: one that has two parallel diagonal lines written on the front, indicating that the amount of money specified in the check must be deposited into a bank account or, failing that, cashed by another credit institution, but not paid in cash.
• Traveler’s or traveler’s check: one issued by a bank in the name of a person and that is payable by another establishment of the same institution or by another bank, either within the same country or abroad.
• Cashier’s check: the cashier’s check, also known as a cashier’s check, is one issued by a banking institution in the name of a person or beneficiary, since it is the bank itself that, in this case, acts as a drawer.
• Certified or conformed check: one where the banking institution itself endorses the existence of sufficient funds to pay the amount of money specified in the check.

Sverige som partner 1319–1905. Ett perspektiv
Harald Gustafsson
Fulltext (pdf)
Sweden as partner 1319–1905: A Perspective
During most of the period from 1319 to 1905, the kingdom of Sweden formed part of a larger state, either through union with other states or through the possession of provinces that were not part of the kingdom proper. This is a neglected theme in Swedish historiography, where Sweden is described as a trans-historical entity, sometimes larger and sometimes smaller than the present state but still basically one and the same political unit. In an attempt to overcome methodological nationalism, this article presents what can be called a trans-territorial perspective on the development of the Swedish state. Sweden’s history as partner is followed from the personal unions with Norway and Denmark in the late middle ages, through Sweden’s early modern experience as the centre of a conglomerate state, to the 19th-century union with Norway.
The medieval unions were loose, basically dynastic connections where each kingdom kept its domestic laws, political institutions and social organisation. The early modern conglomerate state was more firmly held together and ruled from Stockholm, especially with regards to the public finances and foreign policy. But each province kept its distinct internal organisation, which allowed for considerable political influence to be exercised by the local political elite. In this perspective, the often neglected integration of the Scandinavian provinces into the realm in the early 1680s is unusual and interesting, even more so than the well-studied acquisition in 1658. In a long trans-territorial perspective, it becomes clear that the weakness of the 19th-century Swedish-Norwegian union was that it attempted to house two modern nation-states within one state.
A trans-territorial perspective on Swedish history gives rise to many new questions that have been neglected in the dominant national narrative. For example, was the adoption of a national law code in the 1350s the result of inspiration from the union partner Norway, which had a more centralised judicial system? Was the strengthening of the state apparatus under the rule of Gustav Vasa in the 1500s possible because the territory of the Swedish state was unusually homogeneous after the break-up of the Union of Kalmar and before the acquisition of Estonia? What was the influence on Sweden proper from the possession of the provinces east and south of the Baltic? How did the Swedish experience of ruling a conglomerate state influence Swedish policy towards Norway in the formative phase of the 19th-century union? Much is to be gained by adopting a non-national perspective on Swedish history.

Elite Classic
Like rays of light darting out from the sun, the pattern of the Elite Classic's dial creates a spectacle of highlights and shadows. The dial is set with tapered hour markers that are faceted and polished. The minutes and seconds track lend the dial a scientific touch, while slightly larger applied hour markers break up the track and highlight the four cardinal points of the dial. Floating above the lively dial are sharp and slim “Dauphine” shaped hands, a nostalgic nod to Zenith watches from the mid-20th century.

Question: What is the most accurate type of age dating?
Radiocarbon dating One of the most widely used and well-known absolute dating techniques is carbon-14 (or radiocarbon) dating, which is used to date organic remains. This is a radiometric technique, since it is based on radioactive decay.
What is exact age dating?
Absolute dating assigns a numerical age based on the objects natural radioactive decay. The two methods are often used in conjunction to determine geologic age.
Which type of dating gives the most accurate historical time frame?
radiocarbon dating Perhaps the most famous absolute dating technique, radiocarbon dating was developed during the 1940s and relies on chemistry to determine the ages of objects. Used on organic matter, the technique measures the amount of radioactive carbon decay to determine an objects age.
What type of dating is more likely to give you an accurate idea of the age of a fossil?

Christmas Wreath Pavlova
Serves 8
1. Preheat oven to 120C fan-forced
2. Add egg white and a tablespoon of sugar to your stand mixer fitted with the whisk. Whisk on medium until the egg whites begin to turn white and foamy. Then slowly add a tablespoon of sugar at a time while mixing until all sugar is added. Continue whisking until the meringue is thick, white and glossy with all sugar dissolved. Check this by rubbing a small amount of meringue between two fingers, if grainy, keep whisking.
3. Then trace around a small dinner plate (20-25cm) onto baking paper. Then trace around a coffee cup inside that circle to create a stencil for your wreath shape.
4. Place the baking paper onto a round baking tray and spoon big dollops of meringue onto the stencil, keeping in the lines as best you can. Once you’ve used all your meringue, let it ‘air dry’ for 10 minutes then place into the oven to cook for 50 minutes or until the meringue shell is hard.
5. While the meringue is cooking, combine curd ingredients in a small saucepan until completely smooth. Then put the saucepan onto your smallest hob on your stove. Heat it gently on low, stirring constantly, until the curd comes together and thickens to coat the back of a spoon. This usually takes about 15 minutes. Set this aside to cool while your meringue finishes cooking.
6. Place the cream ingredients into a stand mixer fitted with a whisk. Whisk on medium until soft-medium peaks form. Keep in the fridge until you’re ready to dress your pavlova.

Negro Spirituals and Its History
The Start of Negro Spirituals
During slavery, African Americans were forced from their native land to commit to the normative of the enslavers, White Americans. This caused traumatic experiences, pain, loss of oneself and identity.
Negro Spirituals became an outlet of pain, struggles, and a time passer for enslaved people. This was was a coping mechanism that consisted of story telling or praise; It created a sense of unity African Americans. It would sometimes be a way of communication between the enslaved
Fisk University
Fisk university was founded in 1866 by the American Missionary Association. The purpose of the university was to educate emancipated slaves. Due to struggling financially, the students would perform spirituals locally and internationally to raise money for the school. Folk Spiritual music then became popular due to African Americans supporting and carrying it along throughout the years. It is now preserved through HBCUs.
Popular Negro Spirituals

Importance of Negro Spirituals Today
This religious aspect of black culture is seen in Negro Spirituals and Black institutions such as HBCUs. To this day, many of these schools continue to practice Christianity traditions through church service at school, celebrations, religious based curriculum, etc.
Many vocal elements of Negro Spirituals still influence R&B today. R&B consists of the same rhythmic patterns.
Gospel today is still strongly inspired and influenced by Negro Spirituals today just as they were in the past. Gospel isn continuously shaped bye Call & Response, hope, and God.

Earthquake refers to the sudden violent movement of the earth’s crust. It creates seismic waves. It often causes great destruction. Its causes and effects are mentioned below.
Causes of Earthquakes
The important causes of the earthquake are:
Natural Causes of Earthquake:
1. Tectonic Movement: This particularly happens when the continental plate collides against the oceanic plate. The oceanic plate is overridden by the continental plate. By a process called subduction jerky movements are caused along the inclined surface. Tectonic earthquakes have occurred in Assam in 1950.
2. Volcanic Activity: Earthquakes may also be caused by the movement of lava beneath the surface of the earth during volcanic activity. The earthquakes due to Krakatoa volcanic eruption in 1883 is a good example of volcanic eruption.
3. Dislocation of the Earth’s crust:Earthquakes may be caused by the dislocation of the crust beneath the surface of the Earth.
4. Adjustment in inner Rock Beds:Earthquakes are also caused where is an adjustment between Sima [i.e., beneath the ocean is formed by Silica and Magnesium = Si + ma = Sima] and Sial (i.e., Continent is formed by Silica and Aluminium = Si + al = Sial) in the interior of the Earth’s Crust. This Earthquake may be called as a Plutonic Earthquake.
5. Pressure of gases in the interior: The expansion and contraction of gases in the interior of the Earth sometimes cause a sudden shake on the Earth’s surface.
6. Other Causes:
1. Landslides and avalanches,
2. Denudation of the Landmasses and depositions of materials,
3. Faulting and folding in the rock beds are responsible for causing minor earthquakes.
