Mach Principle presents the absolute universe. For example, when you stand on the ground and relaxed, your arms fall down naturally. However, if you rotate your body then your arms are lifted up as the rotation is faster and faster. Mach principle is that the matter of the whole universe can affect local dynamic systems. That is, the matter of the whole universe sets up the local absolute reference frames. However, both the theories of general relativity and Big Bang are against the absolute reference frames of Mach Principle. Here I present a simple model of flat universe which is consistent to most cosmic laws, and Mach Principle is recovered amazingly.

Discovering the Treemendous Playground in St. Peter
Compared to those of my childhood, the playgrounds of today seriously blow me away. I could only have imagined such beautiful playgrounds in my dreams as a child. While the swing sets, teeter totters, and merry-go-rounds of the past were loads of fun, they can’t compete with some of the modern day playgrounds that blend art with imagination and fun.
While spending a day in St. Peter a while back, the kids and I discovered one such incredible playground. The minute I saw the Treemendous Playground, I fell in love. It depicts the scene of an old river town and includes murals of people and animals.The children of St. Peter also provided ideas used in the design including a forest, a bear’s den, a steamboat, a covered wagon, a log cabin and a school house.
History of the Treemendous Playground
The Treemendous playground is located at Gorman Park. The park is named after Willis A. Gorman, a Territorial Governor of Minnesota who served in 1853. While he was governor, Gorman proposed moving the capital of Minnesota from St. Paul to St. Peter. Legislator Joe Rolette blocked his attempt by stealing his proposal while the Legislature was in session. Willis Gorman also served in the Mexican-American War and the Civil War.
In 1998, a tornado struck the town of St. Peter and destroyed many of the towns famous old growth trees, including some at Gorman park. The loss of the trees became part of the inspiration for the Treemendous Playground. After months of planning, over 2000 volunteers from the community came together to help with the construction of the playground!

Dragon is the totem of Chinese culture. At present, most of the dragon patterns we see are the same. Antlers, Locke heads, snake necks, turtle eyes, ox ears, fish scales, Eagle claws and tiger paws are unique features of dragons. In thousands of years of history, the dragon is the incarnation of the emperor and the rich. One of the twelve zodiac signs is the symbol of the Chinese nation. Dragon fish and dragon culture dragon fish culture knowledge dragon fish, similar to the dragon. The dragon fish has double whiskers, pectoral fins like dragon claws, thick scales all over, and it is quiet as a virgin, and East as a rabbit. The swimming posture of dragon fish and dragon culture is flexible, giving people a noble, generous and peaceful momentum, more like a dragon. For many years, the Chinese nation has been advocating dragon culture and inheriting dragon spirit. However, in fact, the dragon does not exist. It is just a kind of magic thing. People can only worship in their hearts. The appearance of dragon fish breaks people's attitude of admiration. Dragon fish is like a dragon. Naturally, dragon fish is also known as the incarnation of the dragon. Most people don't want to give up the chance to be close to the Dragon avatar. According to statistics, most people who have seen dragon fish want to raise them, just because of the price of dragon fish. It's a good breeding condition for chili red dragon or blood red dragon that makes many people stop. But even so, it still can't prevent the dragon fish from entering thousands of households. The dragon fish breeding is still popular, the price is always high, and the dragon fish culture is increasingly recognized.

Strategic National Stockpile
The Centers for Disease Control and Prevention (CDC) maintains the Strategic National Stockpile (SNS). SNS consists of large quantities of medicine and medical supplies to protect the American public if there is a public health emergency, such as a terrorist attack, flu outbreak and/or earthquake, severe enough to deplete local supplies.
Once federal and local authorities agree that the SNS is needed, medicines will be delivered to any state in the United States within 12 hours. Each state has plans to receive and distribute SNS medicine and medical supplies to local communities as quickly as possible through Open POD (Point of Dispensing) sites.
Alabama SNS plans also include delivering medications and medical supplies through Closed Point of Dispensing (POD) sites located throughout the state. According to CDC, “a Closed POD is primarily used to respond to a specific group or organization.” The use of Closed POD sites allows for rapid dispensing within organizations and helps to ensure continuity of organizational operations, while also redirecting some of the population away from community Open POD sites.

You get angry over the littlest things
Tend to morph into the Hulk when you’re upset? Those fiery emotions can drastically increase your risk for a heart attack. Researchers at the University of Australia questioned 313 patients who had suffered suspected heart attacks about their anger levels before the onset of symptoms. They found that patients were 8.5 times more likely to have a heart attack in the two hours following an intense outburst of anger, defined as “very angry, body tense, clenching fists or teeth.” The more often you’re angry, the higher your chances for a heart attack.
You spend most of your time in front of a screen
Yes, that includes working on your computer. A study from the University College London reports that people who watch TV or work on a computer for four or more hours a day increase their risk of an event associated with cardiovascular disease, like a heart attack, by 125 percent. Long periods of sitting deplete the body’s supply of lipoprotein lipase, an enzyme that breaks down fat and prevents clogged arteries. If you spend most of your day plopped behind a desk, take a brief walk after every 20 minutes or try a standing desk. You can burn 30 percent more calories when you stand than when you sit. Don’t miss these 15 doctor-approved tips to prevent heart disease.

Revelation given to Joseph Smith the Prophet, at Wayne County, New York, in 1830. Even before the organization of the Church, questions had arisen about the proper mode of baptism, leading the Prophet to seek answers on the subject. Joseph Smith’s history states that this revelation is an explanation of 1 Corinthians 7:14, a scripture that had often been used to justify infant baptism.
2 Now, in the days of the apostles the law of circumcision was had among all the Jews who believed not the gospel of Jesus Christ.
3 And it came to pass that there arose a great acontention among the people concerning the law of bcircumcision, for the unbelieving husband was desirous that his children should be circumcised and become subject to the claw of Moses, which law was fulfilled.
4 And it came to pass that the children, being brought up in subjection to the law of Moses, gave heed to the atraditions of their fathers and believed not the gospel of Christ, wherein they became unholy.
5 Wherefore, for this cause the apostle wrote unto the church, giving unto them a commandment, not of the Lord, but of himself, that a believer should not be aunited to an bunbeliever; except the claw of Moses should be done away among them,
6 That their children might remain without circumcision; and that the atradition might be done away, which saith that little children are unholy; for it was had among the Jews;


Groundwater loss in India and an integrated climate solution
Reference: Soni, V, 2012, 'Groundwater Loss In India And An Integrated Climate Solution', Current Science, vol. 102, no. 8, pp. 1098-1101
We use ground agricultural data to assess the loss of water in the cultivated area in northwest India and find that this loss is about 3.5 times the reported average loss over the whole area using NASA gravity satellite, ‘GRACE’, data. This long term water deficit would result in a loss of 40% of the cultivated area.
If some of this area is turned into forest agriculture, water loss may be recovered in about forty years. Forest agriculture can also substantially cut total carbon emissions. The article addresses long term water policy for the country.


Physical activity is often considered beneficial for a healthy sleep. A lot of exercise can increase the duration and quality of sleep by stimulating the production of serotonin in the brain and lowering the stress hormone. If you exercise during the day you lose your energy and you get tired faster. However, it is important not to overdo it. Excessive training is linked to poor sleep, so train in moderation! The time at which you train is also crucial. To promote better quality sleep, training in the morning seems to be better than training in the middle of the day.
14. Avoid naps during the day
Due to poor sleep at night, people with insomnia tend to take a nap during the day. Although naps are short- and often linked to improvements in alertness and well-being, there are mixed opinions about the effects of naps on sleep. Some studies have shown that regular naps can lead to poor nighttime sleep quality and even sleep deprivation. The opinions are different, but try to get your rest mainly at night.
15. Experience both daylight and darkness
Light can affect the internal clock of your body in terms of sleep and vigilance. Irregular exposure to light can cause a disturbance in your rhythm, making it more difficult to fall asleep. During the day, exposing your body to bright light indicates that it must remain alert. At night, darkness promotes feelings of sleepiness. Research has even shown that darkness increases the production of melatonin, an essential hormone for sleep.


Qing Ming, the day that family visit their ancestors at the tomb or niche to do some clean up and pay their respects. In the modern and busy Singapore, time seem to pass real quickly and every year Qing Ming creeps into the calendar of many family. It feel kind of like a responsibility, yet it has to be done, for families that values its past and history anyways.
Qing Ming has turned out to be a day where family members gather, aside from Chinese New Year, to do something together, visiting places, getting things done. Qing Ming for my family is a day of gathering, we gather together to visit and pay our respects at a few of the places that we head to every year, mainly Mandai and Mt Vernon.
We bring paper money, joss sticks and fruits as part of the tradition. After we paid our respects, cleaned the niches of our ancestors, we lay the fruits and paper money out, lit the joss sticks and waited for the joss sticks to be “consumed” while we chatted at the side, squeezing at the corridor with many other people that are there during the weekend.
After all the work for each place is done, we consolidate the paper money and burn them at the large burning area. We spread out all the money, using the age old method, burn the money part by part, slowly, to ensure that the paper money are all burned. It’s very hot during the process of burning but that’s what children enjoy and it’s the process of burning and paper spreading that is fun.
Soon is lunch, or early dinner, much depending on the time that all the location has been visited or task has been completed. My family gathers for a meal before heading off into separate ways, waiting again for the next year’s Qing Ming.

Proton = +
Neutron = 0
Electron = -
- Non metal + non metal = covalent (sharing electrons)
- Metal + non metal = ionic (transferring electrons)
- Metal + metal = metallic (delocalised electrons)
When an element looses electrons it becomes positively charged.
When an element gains electrons it becomes negatively charged..
This is because protons outweigh electrons.
Group 1 alkali metal + Group 7 halogen = +ve metal ion + -ve halide ion
The metal atoms lose electrons to form positive ions. The non metal atoms gain electrons to for negitive ions. Opposites attract and this is ionic bonding.
An ionic compound is a giant structure or lattice. They are held together by strong electrostatic forces of attraction that act in all directions.
Represented by dot and cross diagrams.
The charges in the ionic compound always cancel each other out.
- 2 non metals sharing electrons
- Very strong bonds
- Number of covalent bonds and an atom forms depends on the number of electrons it needs to achieve stable electronic structure
- Some have giant covalent structures, as covalent bonds are only between 2 atoms. Some substances are made of several molecules
Examples: Hydrogen, Chlorine, Oxygen, Methane, Ammonia, Hydrochloric acid, Water
- Giant structure
- Atoms in metals are all the same size and arranged in regular layers
- Electrons in the outer shell of the atoms are delocalised
Delocalised electrons can move about freely between the positively charged ions. This acts as a lattice of positive ions to hold the structure together, as the negitive electrons strongly attract the positively charged ions with an electrostatic force.


The ability of high-resolution mesoscale models to simulate near-surface and subsurface meteorological processes is critical for representing land–atmosphere feedback processes. The High-Resolution Rapid Refresh (HRRR) model is a 3-km numerical weather prediction model that has been used operationally since 2014. In this study, we evaluated the HRRR over the contiguous United States from 1 January 2021 to 31 December 2021. We compared the 1-, 3-, 6-, 12-, 18-, 24-, 30-, and 48-h forecasts against observations of air and surface temperature, shortwave radiation, and soil temperature and moisture from the 114 stations of the U.S. Climate Reference Network (USCRN) and evaluated the HRRR’s performance for different geographic regions and land cover types. We found that the HRRR well simulated air and surface temperatures, but underestimated soil temperatures when temperatures were subfreezing. The HRRR had the largest overestimates in shortwave radiation under cloudy skies, and there was a positive relationship between the shortwave radiation mean bias error (MBE) and air temperature MBE that was stronger in summer than winter. Additionally, the HRRR underestimated soil moisture when the values exceeded about 0.2 m3 m−3, but overestimated soil moisture when measurements were below this value. Consequently, the HRRR exhibited a positive soil moisture MBE over the drier areas of the western United States and a negative MBE over the eastern United States. Although caution is needed when applying conclusions regarding HRRR’s biases to locations with subgrid-scale land cover variations, general knowledge of HRRR’s biases will help guide improvements to land surface models used in high-resolution weather forecasting models.

Against the background of a growing number of electronic devices being implanted in patients in order to treat various diseases – including arrhythmia, parkinsonís disease, deafness and diabetes – the development of miniaturized technologies capable of producing electrical energy has turned into a principal ambition for different scientific disciplines. In this context, nano- and microtechnology provide challenging new tools to access macroscopic and microscopic biochemical systems inspired by natureís energy production concepts. Mostly, these systems are characterized by being self-renewing and possessing an enormous degree of efficiency. In particular, the fusion of “living” biomaterial – such as cells – with synthetic systems will enable access to groundbreaking new bionic technologies in the future.
The objective of this project is the development of a bionic microgenerator as a macroscopic power supply, facilitating low-loss conversion of chemical to electrical energy by self-integration of synthetic and biological building blocks. This system, orchestrating molecular, nanoscopic as well as microscopic components, harnesses the electrochemical resting potential of eukaryotic cells or bioengineered lipid vesicles with genetically modified, membrane-reconstituted ion pumps and channels which control the voltage potential generated between the intra- and extracellular compartment. Therefore, cells will be plated on 3-dimensional arrays of partly isolated, monocrystalline metal nanoelectrodes generated by a combination of chemical and physical methods.
Such bionic generators have the great potential to serve as efficient power supplies for a wide range of applications, such as self-regenerating and biocompatible prostheses or body implants, like cardiac and brain pulse generators, cochlear implants, insulin pumps or devices to monitor body functions.


On June 5 - 6 this year, curious eyes can catch a glimpse of the beautiful planet of Venus. Named after the roman goddess of love and beauty, Venus is the second planet from the sun after mars. So what makes Venus so special?, well apart from having similar characteristics to earth such as size, gravity and it's composition it is also the 3rd brightest natural object in the night sky after the sun and moon. As a result of its brightness, every 243years (in pairs of 8years) when Venus gets round the sun to the point where it crosses the earth, one can catch a glimpse of this bright and beautiful planet of love and beauty. This is a rare historical event occurring in your lifetime and not to be missed. So mark the date and escort Venus across earth. Visit http://www.transitofvenus.org/ to learn more about this historic event.

The word "prey" is used when describing an animal or a human being that is attacked or assaulted by another animal or human. Notice that this word is different from "pray," which is spelled with an "a."
Wolves prey upon rabbits.
Snakes prey on mice.
A story in the newspaper tells of an incident in which a salesperson preyed upon elderly people and cheated them out of millions of dollars. Eventually he went to jail.
Men who prey upon vulnerable women should be ashamed of themselves.
People who appear to be gullible are preyed upon by those who lack a sense of morality and decency.
The word "prey" is also a noun:
Snakes go after live prey.
The salesperson marked the customer as easy prey. (It would be easy to make sale to this customer.)
Without a healthy supply of prey, certain carnivorous animals will starve to death.


Scientists spot pulsar with 4 magnetic poles
The 209th Meeting of the American Astronomical Society (AAS) in Seattle has been entertained by the news that the neutron star within the Crab Nebula may have twice the normal complement of magnetic poles, the BBC reports.
The nature of the star's radio pulse emissions leads the Arecibo Observatory in Puerto Rico to conclude that it possibly has four magnetic poles. Depending on a pulsar's orientation to Earth, its rotation and said emissions issuing forth from the poles will allow detection of one or two pulses. Where two are detected, as is the case in the Crab Nebula, the emissions from the north and south poles should be identical.
In the case of this particular neutron star, however, scientists detected a main pulse, occasionally producing "enormously strong pulses" dubbed "megapulses", and an "interpulse" which were "dramatically different in their profiles".
Tim Hankins, acting director of the Arecibo Observatory in Puerto Rico, explained: "We think we've got a much more complicated magnetic field than the simple dipole model. What we think is that there is another pole, possibly with a partner, that is influencing and distorting the magnetic field."
The four-pole theory is based on the fact that, although the team has spotted just one extra pole, it will likely have an opposite.
The Crab Nebula pulsar was created as a result of a supernova explosion on 4 July 1054 (AD). Professor Hankins pointed out that the explosion may have been "very asymmetric", adding: "Any models you see of supernova explosions are incredibly convoluted. It just doesn't go down as sphere and rebound as a nice sphere. The magnetic pole is frozen in so it gets all mixed up as well." ®

In 10 seconds? Intense therapy and a technological aid can get people back on their feet after paralysis from spinal cord injury. The key is electrical stimulation below the point of injury, which helps activate the neural pathways that trigger movement.
Wow, how did they work this out? Two different teams worked on the idea that even after severe spinal cord injury, there are signals running from the brain to the limbs, but they aren't strong enough. They enrolled patients in intense training and implanted a device into them that basically boosted the signals, testing a technique called epidural electrical stimulation.


A dye-sublimation print is a full colour printing process that uses heat to transfer dye to white synthetic materials.The printers are similar to inkjet printers in that they spray ink onto a sheet of paper, but the ink is actually dye-sublimation ink.
Sublimation ink is unique in its ability to convert from a solid to a gas without going through a liquid form. The conversion is initiated by heat and controlled with pressure and time. The high temperature – from a heat transfer press – opens the pores of the polyester and allows the gas to enter. When the temperature drops, the pores close and the gas reverts to a solid state. The print then becomes part of the polyester.
Our high quality dye sublimation ink has excellent colour brightness and produces brilliantly crisp transfers.
Screen printing is a stencil method of print making in which a design is imposed on a screen of polyester or other fine mesh, with blank areas coated with an impermeable substance. Ink is forced into the mesh openings by the fill blade or squeege and onto the printing surface during the squeegee stroke. The ink passes through the open spaces in the screen onto the neoprene below. The printed piece is then heat dried at about 200°C.
We can match most Pantone C colours. It is also the most economical printing option if the budget is tight.
We print multi colour designs with plastisol inks, instead of printing designs directly onto neoprene, the design is printed on a special paper. The paper is heated after each colour is applied, and up to six (6) colours can be applied to one design. The resulting print is called a plastisol transfer, which is applied to the neoprene, and placed in a heat transfer press. The heat and pressure applied by the press forces the ink into the neoprene nylon. When the press is opened and the paper is peeled off the neoprene, the ink remains behind.
This is a more traditional multi colour printing compared to the dye sublimation prints.

How Electron Spectroscopy with Synchrotron Light Can Help Us Understand High-Tc Superconductivity and Other Complex States of Matter
How Electron Spectroscopy with Synchrotron Light Can Help Us Understand High-Tc Superconductivity and Other Complex States of Matter All the physical, chemical, and mechanical properties of materials are controlled by electrons that occupy the highest energy levels in solids, those near the Fermi energy. Many techniques were developed to study those electrons, leading to the great successes of condensed matter physics. Newer and complex materials, such as the high-temperature superconductors, tend to exhibit very large anisotropies in their physical properties, requiring a more detailed knowledge of the behavior of electrons not only as a function of their energy, but also their momentum. Angle-resolved photoemission can contribute to our understanding by providing a great deal of information on many of the momentum-dependent properties of electrons and their interactions. In this talk, I will present a brief overview of how a long-term and focused collaboration between scientists at Argonne and other institutions has contributed to making angle-resolved photoemissions a most useful tool in the study of complex states of matter.

To have a nationality is a human right. But between the nineteenth and mid-twentieth centuries, virtually every country in the world adopted laws that stripped citizenship from women who married foreign men.
Despite the resulting hardships and even statelessness experienced by married women, it took until 1957 for the international community to condemn the practice, with the adoption of the United Nations Convention on the Nationality of Married Women.
Citizenship, Alienage, and the Modern Constitutional State tells the important yet neglected story of marital denaturalization from a comparative perspective. Examining denaturalization laws and their impact on women around the world, with a focus on Australia, Britain, Canada, Ireland, New Zealand and the United States, it advances a concept of citizenship as profoundly personal and existential. In doing so, it sheds light on both a specific chapter of legal history and the theory of citizenship in general.

Leaning Tower of Pisa © Andrew Crump
The holiday destination of Pisa is most famous for its leaning campanile; yet its other equally notable coups include its long maritime legacy, dating to 1000 BC, its prized university, and its status as the birthplace of the world's greatest physicist and astronomer, Galileo Galilei. The Pisans also created one of the most beautiful squares in the world in the Campo dei Miracoli (Field of Miracles).
Pisa's key component is the famous Leaning Tower, an essential holiday attraction, whose layers of heavy marble were constructed on a shifting subsoil foundation that has been the bane of Pisan engineers for more than 800 years. It seems that the tremulous soil underneath the Field of Miracles has exacted its price on the other buildings too, most notably San Michele dei Scalzi. Other attractions of interest in Pisa include the Museo delle Sinopie, a museum containing a display of sketches from the frescoed cycle that decorated the walls of the Campo Santo cemetery; and the Museo dell'Opera del Duomo, in which exhibits of arabesque panels and Corinthian capitals reveal the influences of Rome and Islam on Pisan architects. The Museo Nazionale di San Matteo displays a range of Florentine art from the 12th through to the 17th-centuries.
Pisa is a popular daytrip from Florence, and a beloved Italian destination in its own right.


The noun people is very unusual in English. It can take singular or plural verb forms and can have its own plural form peoples. As I say in A Guide to English Language Usage:
person and people
For almost all purposes people is the effective plural of person. It can follow a number and takes a plural verb: 1,500 people have bought tickets; the people who were (not was) present. However, people is not plural in origin. It comes from Latin populus, and has its own singular and plural forms corresponding to community, tribe, race, nation or ethnic group. So it is perfectly correct to speak of a warlike people; a peace-loving people; the peoples of Europe; Winston Churchill wrote A History of the English-Speaking Peoples.
Today’s Observer has an article about the elections to beheld in Catalonia on 25 November. It says of the governing CiU party:
The campaign slogan is “the people's will”.
Not quite. In Catalan it is La voluntat d’un poble and there we have the Catalan version of that Latin populus. It is unquestionably used in the singular form, equivalent to French peuple or German Volk. It could be argued that the people’s will means the will of the people, with people being understood a singular. But that is not quite right since the Catalan has the indefinite article, and in any case the use of people in English in such contexts is usually parsed as plural even when there is no clear indication one way or the other.
This blog is about language. Comments on the use of people singular or plural are welcome. Comments about the Catalan election itself are not welcome.


Being a firefighter is a very dangerous occupation, although it's been getting slightly safer over time. According to the National Fire Protection Association
, almost 3,600 firefighters died on the job between 1981 and 2011. That's an average of about 115 occupational deaths per year for firefighters, although fortunately there's been a slight downward trend and the number of deaths last year was only about half the historical average at 61, setting a new record low.
The number of annual injuries for firefighters has been declining as well, but there were still almost 72,000 incidents last year. That means that almost 200 firefighters were injured on-the-job every day in 2010. There were slightly more than one million firefighters in 2010 (including 768,150 volunteers), which means that more than 6.5%, and more than one out of every 15 firefighters, were injured or killed on the job in 2010. That's a lot better than the 10% share of firefighters who were injured or killed in 1991, but it still makes firefighting one of the most dangerous jobs in America
(based on both occupational fatalities and on-the-job injuries).
But there are huge, and persistent gender gaps for firefighters (along with huge gender occupational fatality gaps and huge gender occupational injury gaps), with male firefighters outnumbering female fighters by almost 27-to-1 (96.4% male vs. 3.6% female
Q: Shouldn't the huge gender disparities in firefighting employment, injuries and deaths motivate applying Title IX legislation to this industry with the goal of perfect gender parity?


Hungarians come together on April 11th of each year to celebrate The Day of Hungarian Poetry. Held on the birthday of famed Hungarian poet Attila József, the event has been going since 1964 and brings young and old together to celebrate the inspiring achievements of their country’s greatest literary geniuses.
Famed writer and poet Sándor Márai was also born on this same day. In addition, important Hungarian poets such as Sándor Weöres and Sándor Petőfi are also remembered on this day.
In Budapest, József Attila’s birthplace was filled with songs and poetry recitals, as cultural and political leaders came together to remember the tragic genius who committed suicide in 1937 at the age of 32.
In addition, similar ceremonies were held throughout the country. As students in Pápa recited Petőfi, a “wall of poems” was erected in Szombathely next to a statue of Sándor Weöres, and a “poetry tram” wound its way through the streets of Debrecen.


Some people consider toilets dirty — their germs dangerous. But others see them as icons of health that actually save lives.
Today, a full 36 percent of the world's population lives without a toilet, says the newest data from theWorld Health Organization. That's one in three.
If even half of the 36 percent could get regular access to a toilet, thousands of children would be spared from death every year — 400,000 between now and the year 2015.


‘Victims of Injustice and violence’
Sculpture by Chaim Stephenson to remember all victims of injustice and violence in South Africa during the years of apartheid.
Chaim Stephenson was born in Liverpool to Russian immigrant parents. Profoundly affected by the Holocaust, he moved to Israel and was one of the founders of Kibbutz Yas’ur in Northern Israel where he met British author Lynn Reid Banks. The family returned to England in 1971.
In 1991 he was commissioned to create a bronze sculpture to commemorate the anti-apartheid struggle in South Africa. It can be seen inside Saint Martin in-the-Fields in London.

Portrait of the week - The doctor's visit
The doctor's visit, painted by Jan Steen, circa 1660.
This portrait of a sick woman, accompanied by a doctor and a maid, is a perfect example of painting in the Netherlands of the 17th century - paintings primarily aimed at the up-and-coming bourgeoisie and showing interiors (most commonly, but sometimes exteriors) with ordinary scenes and situations.
Showing ill women were not thought of as an unsuitable motif, but appears several times by different artists, for example by Caspar Netscher, and Jan Steen also painted 'The love-sick woman' with an almost identical setting.
The woman is seen in an upper-class setting, with large paintings on the walls and thick fabrics on the furniture. In the corner a four-poster-bed is seen. The woman is dressed in fur-trimmed jacket and a dress made of grey silk. This was not what a proper woman would wear in at a more formal occasion, this was a dress made for home, and suitable to wear when ill. The doctor is checking her pulse, and the maid is holding a urine-sample in a glass-bottle. The medical art of the 17th century was not the most advanced, that must be admitted, but they had by now come to the conclusion that checking the heart-beat and the urine was vital for understanding a patients well-being. Just as a doctor would nowadays. The difference might be more in the remedies that were prescribed, like bloodletting and sweatings (to get the body in balance).
The maid is shown as helping out the doctor, holding things for him and talking to him. That she is merely a servant-woman and not, for example, the sick woman's mother, is clearly shown by the difference of clothing, this woman's dress is much simpler and she even has an apron, though in a bright, blue colour.


Kid Thomas Valentine - trumpet
Kid Thomas is still revered today in Algiers Louisiana. Jazz musicians of the 1920s referred to Algiers as “over da river” or the “Brooklyn of the South,” the latter for its proximity to New Orleans as compared to New York and Brooklyn, both separated by a river. Algiers Point has a long, rich history of African American, French, Spanish, German, Irish, and Italian/Sicilian residents. Algiers, the second oldest neighborhood in New Orleans after the French Quarter, was the site of the slave holding areas, newly arrived from Africa, the powder magazine, and slaughterhouse of the early 18th century. Many of the Jazz venues have long since disappeared, as have many of the musicians’ homes. Most of the saloons, and dance halls are all but forgotten now by the modern-day Algiers’ residents. Gone are the days of Jazz funerals every week, the sound of dancing feet in the juke joints, and dance halls, and corner saloons.

In the Logic School, students take the mastered information from the Grammar Stage and bring it into ordered relationships. Students begin to apply logic, assessing the validity of arguments and learning to view information critically with more discerning minds. Through classical methods, the students are encouraged and trained to form solid supports for arguments and to identify and refute weak or false claims.
This is the stage in which the melding and blending of classical methods with a Biblical worldview are crucial. In the quest for answers to questions, many of them quite difficult ones, teachers assure students of the authoritative and timeless truths of God’s word.
Some methods used to obtain these goals include Socratic seminars, recitations, mock trials, debates, and analysis of primary source documents.

Looking at the starry sky, people think that it is all static and calm. The planets and the moon bring some happenings, but there still remains a sense of great boredom. Sometimes with the appearance of comets and asteroids, the interest in astronomy increases, but very quickly it all falls into oblivion. However, all this is not as peaceful as many think. Great events and great changes are happening in the universe that cannot be seen with the naked eye from Earth. Here we can understand the incredible size of the universe, and the space in which all these changes take place.
Modern devices and telescopes register events that are extremely large and energetically strong that people can never understand. Magnificent explosions, incredible bursts of energy, compression of matter and much more – gives guidance to people on their way to understanding the space in which we exist. Of course, if we understand the part – that’s a big deal.

Gun cameras are cameras used primarily in aircraft to help measure tactical effectiveness. These cameras are triggered by the firing of a weapon, hence the name.
The use of gun cameras first became common for gunnery training in the 1920s though examples were used during World War I by the BritishRoyal Flying Corps. A special version of the standard Lewis Machine gun was manufactured as a Camera Gun. During World War II, gun cameras were commonly used on operational aircraft to record kills of enemy aircraft. Some of this footage survives to this day and is often the source for stock footage in World War II movies, TV shows or video games.
The term guncam may also refer to software that records video game footage, it is often triggered by the firing of a weapon in a way similar to the original guncams of World War II. Some popular examples of this software are Growler Guncam and Java Guncam.


County, South Carolina, United States
Fairfield, county, central South Carolina, U.S., consisting of a hilly piedmont region. The Broad River forms the western boundary, and the Wateree River and Wateree Lake form part of the eastern boundary. Monticello Reservoir, Lake Wateree State Park, and the eastern portion of Sumter National Forest lie within Fairfield county.
In the mid-18th century the area’s favourable climate and the expanse of available lands attracted settlers from mid-Atlantic coastal colonies and from Carolina lowlands. When British troops occupied the area in 1780 during the U.S. War of Independence, Lord Cornwallis, the British general, allegedly remarked on its “fair fields,” hence the county’s name; it was organized in 1785. In 1865 Union forces led by General William Tecumseh Sherman raided the region and partially destroyed the county seat, Winnsboro. Formerly a leading cotton-growing region, it fell victim to the boll weevil infestation of the 1920s. With the abandonment of cotton-based agriculture, most of its terrain subsequently became covered with forests, of which pine is most common.
By the late 20th century agriculture was of lesser importance to the economy, surpassed by the logging and lumber industry and the manufacture of truck and bus bodies and textile products. Area 686 square miles (1,778 square km). Pop. (2000) 23,454; (2010) 23,956.


I’ve been teaching plant physiology or related courses for a long, long time, and one of the tenets is that woody plants don’t heal. In contrast to animal tissues, when trees and shrubs are wounded the damaged tissues are permanently destroyed. Wounds are compartmentalized and covered with wound wood. Arborists are fond of saying "plants seal, not heal."
That’s all fine and good for woody plant parts, but what about grafts? Since grafting reconnects cambial and phloem tissues, is this "healing?" And what about nonwoody plants, like annual flowers and vegetables?
Oddly, this type of information is sadly lacking in physiology textbooks, but it’s a question that I get routinely from gardeners. And it’s not just an exercise in semantics. People make some poor choices in treating tree wounds, for example, laboring under the false impression that such wounds should be treated with wound paint or bandages so they can "heal."


Nearly One-Third of Cacti Are at Risk of Becoming Extinct
Cacti can survive harsh climates, thirsty predators, and a lack of rainfall—but not our actions. Despite the plant’s resilience, approximately 31 percent of the world's 1480 cactus species are now at risk of going extinct thanks to human activities.
A study, published in Nature Plants journal and authored by scientists from the International Union for Conservation of Nature, found illegal collection of live plants and seeds for horticultural trade and private collections is a driving factor behind cacti species’ extinction. According to the study, 86 percent of the endangered cacti used in horticulture were harvested from wild areas. Other practices that harm the plants include residential and commercial development, agriculture, and mining.
"The results of this assessment come as a shock to us," lead author Barbara Goettsch, co-chairwoman of the IUCN's Cactus and Succulent Plant Specialist Group, told the BBC. "We did not expect cacti to be so highly threatened and for illegal trade to be such an important driver of their decline."
While conservationists tend to focus on animals more than plants, only 25 percent of mammals and 13 percent of bird species are threatened, the study pointed out. Meanwhile, cacti serve as an important source of food and water for many animals, including coyotes, deer, lizards, tortoises, bats, and hummingbirds. As cacti disappear, arid eco-systems will be impacted.
The ICUN currently ranks cacti as the fifth most threatened species of endangered flora and fauna, right beneath cycads, amphibians, corals, and conifers. Because of this, they’re calling for international measures to curb illegal cactus harvesting and trading, as well as for the plants to be protected from practices like construction, quarrying, and aquaculture.

In 1862 Charles Darwin wrote to a friend at Kew [Gardens] “I have just received such a Box full from Mr Bateman with the astounding Angraecum sesquipedalia [sic] with a nectary a foot long. Good Heavens what insect can suck it”, and in a second letter just a few days later suggested “in Madagascar there must be moths with probosces capable of extension to a length of between ten and eleven inches [25.4–27.9cm]”. The Guardian
It was 130 years later that Darwin’s prediction was confirmed with the observation, in Madagascar, of Hawk Moth Xanthopan morganii praedicta using its 20cm tongue or proboscis [prəˈbɒsɪs] to feed on orchid Angraecum sesquipedalia.
Video: Georgia Nierfeld
We have 65 species of hawk moths in Australia: like Georgia’s amazing Bee Hawk Moth Cephonodes kingii. While our hawk moths do not have huge 20cm tougues most are in the sub-family Macroglossinae: makros, large + glossa, tongue. Their very long tongues (proboscis) allow them to hover in front of flowers while they access the plant nectar.
Hawk moths hovering in front of flowers are often mistaken for Hummingbirds which are only found in the Americas. The Bee Hummingbird is the smallest bird in the world and at 6cm it is similar in size to our Australian hawk moths.

Citation: N/A Interpretive Summary: Heat treatments can be used to disinfest fruits and vegetables of insects. Such treatments can be used to ensure that imported commodities do not spread quarantined pests without the application of pesticides. In order to assure that such treat- ments are reliable, it is necessary to identify the right combina- tion of temperature levels and treatment times that will kill the insects but not damage the fruit. Estimating the reliability of such treatments requires a mathematical analysis of experimental data in which insect survival is measured over a range of temperatures and treatment times. The present article compares four different mathematical formulas for determining death rates in the Mexican fruit fly using one large set of experimental data. The analysis concludes that a mathematical formula called the "Thermal Kinetic Model," widely used to measure the effec- tiveness of pasteurization of liquids, and a formula called "Probit Analysis," long used to measure the effectiveness of pesticides, give similar and reliable estimates. Two other formulations gave less reliable estimates.
Technical Abstract: A large set of mortality data for the Mexican fruit fly from induced thermal stress was fit to four mathematical models which are used to estimate thermal death points for quarantine level security. Two of the models, the Probit and Kinetic formulas, estimated death point intercepts in close agreement at the tail ends of survivorship curves. Based on the criteria of chi-square values, coefficients of determination, and fiduciary limits, the Kinetic model had the best fit to the data. The Complementary Log-Log Model produced disparately lower death point intercepts with wider fiduciary limits compared to the other three models with the same data set.


Life Skills & Character Development
We want our graduates to be ready for college as good, well rounded individuals that are ready to take on the world. As such, we are developing a character education program for our students. This program will be tied to our name sake - John Adams.
“It is not in the still calm of life, or the repose of a pacific station, that great characters are formed. The habits of a vigorous mind are formed in contending with difficulties. Great necessities call out great virtues. When a mind is raised, and animated by scenes that engage the heart, then those qualities which would otherwise lay dormant, wake into life and form the character of the hero and the statesman.” – Abigail Adams
A Life Skills Course is a required multiyear course that will be developed, monitored, and revised by a committee of founding parents, the principal and key staff members. The Life Skills course or portions of the Life Skills course will be taught by all staff members with few exceptions. College counselors and outside speakers shall be utilized as teachers. The Life Skills course will provide three main functions:
- Teach life skills
- Provide character education
- College counseling objectives
The annual goals and standards of this course shall be developed by the Life Skills Committee. Based on these goals and standards appropriate curriculum may then be chosen or developed.

They are described in detail in the API for DataOutput, an interface which RandomAccessFile implements. Basically, writeChars() uses Unicode values, writing two bytes per character. While writeUTF() uses a slightly-modified version of UTF-8, which uses 1 to 3 bytes per character. Also, writeUTF() writes two bytes at the beginning which identify the number of characters which will be in the UTF-8 representation, so the readUTF() method will know when to stop. The writeChars() method does not do this, and also does not write a delimiter (like 0) at the end of the String - so I'm not sure what it's really useful for. The DataInput interface does not define a readChars() method, because writeChars() does not provide enough information to know reliably where the string should terminate. There are ways to fix this, but in general it's too much trouble - I'd usually just ignore writeChars() and use writeUTF() instead, whenever I have String data to write to a binary file. Of course, if you're writing a text file rather than a binary file, you probably shouldn't be using any of the DataOutput / DataInput methods anyway. They have too many methods which generate unprintable chars if you don't know exactly what you're doing. Use Readers and Writers; they're much better.

New vaccine introduced to protect Pakistani children from pneumoniaListen /
Pakistan on Tuesday became the first country in South Asia to introduce a vaccine to protect children from pneumonia.
UNICEF spokesperson, Marixie Mercado says that pneumonia is the leading killer of children in the world, accounting for 18 per cent of child deaths globally.
"There are four countries in the world that account for more than 50 per cent of these deaths and Pakistan is one of them. In Pakistan, there are over 350,000 children who died each year due to largely preventable causes and pneumonia is the cause behind about 20 of them, 19 per cent of them to be exact."
The GAVI Alliance says it is hoped that by 2015 the vaccine will be in 50 developing countries.
The programmes to vaccinate children have been made possible with $4.3 billion from donor governments.


Pseudoscorpions are small arachnids (less than 1 cm in body length) that superficially resemble scorpions due to the presence of chelate pedipalps at the front of the body. The lack, however, the long tail that is characteristic of all scorpions.
Pseudoscorpions are found in most terrestrial regions of the world from the arctic regions to the hottest deserts. They can be found under rocks, in leaf litter, in soil, under bark of tree or in caves. They feed on other invertebrates such small as insects, which are dismembered utilising their chelicerae. Some pseudoscorpions (the members of the suborder Iocheirata) possess venom glands that discharge through the tip of the chelal fingers. Females deposit their embryos in a brood-sac, which remains attached to the female gonopore on the ventral surface of the abdomen until the embryos
Pseudoscorpions in Australasia
The Australasian pseudoscorpion fauna currently consists of 150 species from Australia and 67 species from New Zealand. Recent research has uncovered a diverse pseudoscorpion fauna in both regions with numerous new species and genera yet to be formally named.
The world fauna was last catalogued by Harvey (1991), and the phylogeny and classification was studied by Harvey (1992).

The Education Act 1944 (Butler Act) required all local authorities to operate a school meals service to provide a midday meal in all schools, for which parents of pupils were charged a nominal weekly sum. This requirement was withdrawn by the Education Act 1980, as was the requirement that school meals meet a minimum nutritional standard, although meals for pupils whose families were on low incomes and in receipt of benefits continued to be provided free of charge. In line with the policy of introducing market competition into all aspects of public life, school meals services were put out by local authorities to tender. This led to what was widely recognized as a decline in nutritional standards. This was addressed in the School Standards and Framework Act 1998, which empowered the Secretary of State to regulate minimum nutritional standards. These standards were put in place in 2002. Nevertheless, the continuing poor nutritional quality of some school meals was subsequently brought to public attention by a campaign conducted by the celebrity chef Jamie Oliver (b. 1975), who has been credited in some quarters with securing thereby an increase in government funding to ensure that minimum standards of nutrition can be met.


The Junior Mythbusters were looking for the stickiest glue possible in order to create a man-sized rodent trap. They think they found it in rodent glue, so put it to the test.
Jesse, Valerie, and Rachel are experimenting with sticky substances to see if a man-sized glue trap can really trap a human. They first begin by testing different types of glue and eventually decide that rodent glue is the strongest.
Next, they test walking across the rodent glue and fashion a rather long walkway with the glue covering it to see if it can get a human stuck. Jesse is challenged to run through the stuff. Do you think he can make it?


In 1931, the University of North Carolina consolidated university system was established, bringing together the state-sponsored institutions at Chapel Hill, Raleigh (then State College), and Greensboro (then the North Carolina College for Women) into a single consolidated university system, sharing a single president and board of trustees.
To promote unity among the students at the three institutions, a Consolidated University Council was created in 1948 to “act as a liaison among the three campuses and to represent the opinions, interests, and welfare of the students.” The Council consisted initially of 11 members, with meetings held quarterly.

The Oxford India Short Introductions are concise, stimulating, and accessible guides to different aspects of India. Combining authoritative analysis, new ideas, and diverse perspectives, they discuss subjects which are topical yet enduring, as also emerging areas of study and debate. Giving identity to over a billion people, the Indian Constitution is one of the world's great political texts. Drafted over six decades ago, its endurance and operation have fascinated and surprised many. In this short introduction, Madhav Khosla brings to light its many features, aspirations, andcontroversies. How does the Constitution separate power between different political actors? What form of citizenship does it embrace? And how can it change? In answering questions such as these, Khosla unravels the document's remarkable and challenging journey, inviting readers to reflect upon thetheory and practice of constitutionalism in the world's largest democracy.

a term for a secondary school, most common in the independent sector. With 'the' definite article, it is also a term for the higher education community generally. In England, since 2000 a (city) academy is a secondary school, centrally funded but with sponsorship from business, faith, or voluntary groups, the aim being to improve standards in areas of disadvantage. The Academy was originally the name given to the school of Plato (427-347 BCE).
both Jean Piaget (1896-1980) and John Dewey (1859-1952) stress learning as an adaptive process whereby the learner makes adjustments in response to interaction with the environment, physical and social. Learning enables one to proceed successfully as a result of such adaptation. Paulo Freire (1921-1997) disliked the term as he felt it lacked a sufficient sense of agency and he preferred to use the term 'integrative' to show the way in which the learner, when free, not only responds to, but is able to act upon, the environment.
courses often of an informal nature aimed at learners beyond the immediate school-leaver cohort. Some may be for interest or pleasure but others lead to qualifications. They can be offered in different models including extra-mural classes, distance learning, within the community, or as weekend and summer schools.

Europe has continuously experienced improved food security since World War II. People are by large enjoying food safety and as food consumers their purchasing power has continuously improved. However, challenges ahead are gradually looming on a global scale due to population growth, climate change and an increasing competition for finite natural resources such as land and water. At the same time the technology driven European food supply, with small emergency reserves, is vulnerable to hostile foreign powers and terrorism.
The chapter analyses how food security challenges can be mitigated and how food security is interlinked with climate change, political unrest and national security. Policies targeting food production efficiency in terms of the use of energy, water and land food production and other parts of the economy in the EU and third countries is demonstrated to be vital to overcome challenges in the long run. Furthermore, increasing public emergency reserves may be motivated, depending on the scope of threats and conflicts on European soil.

During adolescence, internal circadian rhythms and biological sleep drive change to result in later sleep and wake times. As a result of these changes, early middle school and high school start times curtail sleep, hamper a student’s preparedness to learn, negatively impact physical and mental health, and impair driving safety. Furthermore, a growing body of evidence shows that delaying school start times positively impacts student achievement, health, and safety. Public awareness of the hazards of early school start times and the benefits of later start times are largely unappreciated. As a result, the American Academy of Sleep Medicine (AASM) is calling on communities, school boards, and educational institutions to implement start times of 8:30 AM or later for middle schools and high schools to ensure that every student arrives at school healthy, awake, alert, and ready to learn.
Please contact the AASM at email@example.com or (630) 737-9700 if you have any questions about sleep and school start times.

Below are links to resources that physicians, nurses, therapist, or any other health care provider may find helpful in their practices relating to Down syndrome.
Discussing Down Syndrome: Physician’s Guide - created to assist physicians facing the challenge of informing parents that a child has or may have Down syndrome.
Brighter Tomorrows - a free, online training module, funded by the Center for Disease Control and Prevention, for health-care providers on how to deliver a diagnosis in a sensitive manner.
Down Syndrome Clinic – the clinic located at Nemours/Alfred I. duPont Hospital for Children in Wilmington, Delaware, provides coordinated medical, social, and developmental care for children with Down syndrome.
Clinical Report—Health Supervision for Children With Down Syndrome, These guidelines are designed to assist the pediatrician in caring for the child in whom a diagnosis of Down syndrome has been confirmed by chromosome analysis. Although a pediatrician’s initial contact with the child is usually during infancy, occasionally the pregnant woman who has been given a prenatal diagnosis of Down syndrome will be referred for review of the condition and the genetic counseling pro- vided. Therefore, this report offers guidance for this situation as well.

From inside our own consciousness, it seems to us that our thinking and behavior follow a somewhat linear progression in which we perceive the world around us, gather information, interpret what we perceive, decide, and act. From this perspective it’s possible to believe that if we all had access to the same information (and understood it) we’d all reach the same conclusions. But human decision-making is complicated by the fact that our minds are products of the genetically-determined wiring that has evolved over millennia and our individual histories of past experiences, all of which contribute to what we notice, what we think, and what we do. Of course, the structures of human brains evolved in ways that advantaged survival and procreation at a time when the circumstances of human existence were very much unlike those of contemporary society. And as brains developed in even the earliest epochs of human evolution, older structures were not replaced with newer ones; newer structures and enhanced capacities for cognition complemented what was already in place. This combining of older and newer ways of thinking are at the heart of the seeming complexity of how we think, decide, and act.
In a series of five etudes and a culminating discussion, our goal is to reveal the multiple dimensions of human thinking and behavior, illuminating aspects of our perceptions and decision-making that in many ways function outside of our conscious awareness. To quote Professor Gold: “These issues will dominate what our society does about healthcare, quite independently of what our hot-shot science leader thinks flows automatically from omics.”

Today marks the anniversary of the Boston Tea Party on December 16, 1773. Over 200 years after it happened, the incident remains one of the most popular images of the Revolutionary period. That’s no surprise. After all, there’s a certain romanticism to the story of costumed colonists dumping crates of valuable tea into Boston Harbor.
But, while the Boston protest remains the most famous demonstration against the British taxation measures, it was not the only one. There were protests throughout the colonies and one of the most dramatic played out in our own backyard — Annapolis, Maryland — in 1774.


The maple trees in Westminster Abbey represent modesty and the hornbeam trees represent resilience.
A yoke of hornbeam, shaped like a bow, to which the horses were harnessed, was fastened to the other extremity of the pole.
The beech might be used instead of the hornbeam on suitable soil.
The hornbeam was much less common than the ash and was saved with particular care.
It was full of long, straight walks, between hedges of yew and hornbeam, which rose tall and close on every side.
Bowls and dishes of hornbeam lasted forever, and would never leak nor crack.
The European hornbeam was a favorite tree for making the "pleached alleys," of which old-world garden-lovers were proud.
On account of its great toughness the wood of the hornbeam is employed in engineering work for cogs in machinery.
By these hornbeam trees a little streamlet flows out from the copse and under the road by a culvert.

A polymer is a large molecule made up of lots of small molecules. In the natural world, fats and proteins are polymers. A monomer is the name for the small molecule that is part of the chain, in the following example, the monomer is ethene.
The monomers are passed over a heated catalyst and polymerisation occurs. In this example a long chain of molecules called poly(ethene) or polythene is made.
NB: the molecule in square brackets shows the structure of each monomer and the lines coming out show how they are bonded to each other. The letter n denotes that the sequence is repeated many times.
Addition polymerisation is the creation of polymers from monomers containing a C=C bond. As the name suggests it is an addition reaction, and is written as follows:
Above shows the formation of polystyrene, however, many groups could be attached to the C=C, with 4 Fluorenes, Teflon would be made. And a single methyl group results in polypropene.
Polyalkenes are made by the addition polymerization of alkenes. They contain many carbon bonds, which means there is little bond polarity and they are therefore inert which means they are not biodegradable.
Condensation polymers are formed by the reaction of molecules with two functional groups and produces water as a by-product. The first example is the formation of polyesters by the reactions of dicarboxylic acids and diols, forming ester links. For example, in the production of Terylene.
A polyamide is another polyester formed by condensation. It is formed by the reaction of dicarboxylic acids and diamines. This is how Nylon-6,6 is made:
Unlike addition polymers, polyamides and polyesters are biodegradable and can be broken in to their constituent molecules by hydrolysis where water is added to the polymer.
Uses and others
Polymers are very useful, and are used ti replace traditional materials like metals, paper and rubber. The following table shows some other polymers along with their uses.

To the Tashkent Station
Evacuation and Survival in the Soviet Union at War
In summer and fall 1941, as German armies advanced with shocking speed across the Soviet Union, the Soviet leadership embarked on a desperate attempt to safeguard the country's industrial and human resources. Their success helped determine the outcome of the war in Europe. To the Tashkent Station brilliantly reconstructs the evacuation of over sixteen million Soviet civilians in one of the most dramatic episodes of World War II.
Rebecca Manley paints a vivid picture of this epic wartime saga: the chaos that erupted in towns large and small as German troops approached, the overcrowded trains that trundled eastward, and the desperate search for sustenance and shelter in Tashkent, one of the most sought-after sites of refuge in the rear. Her story ends in the shadow of victory, as evacuees journeyed back to their ruined cities and broken homes. Based on previously unexploited archival collections in Russia, Ukraine, and Uzbekistan, To the Tashkent Station offers a novel look at a war that transformed the lives of several generations of Soviet citizens. The evacuation touched men, women, and children from all walks of life: writers as well as workers, scientists along with government officials, party bosses, and peasants. Manley weaves their harrowing stories into a probing analysis of how the Soviet Union responded to and was transformed by World War II.
Over the course of the war, the Soviet state was challenged as never before. Popular loyalties were tested, social hierarchies were recast, and the multiethnic fabric of the country was subjected to new strains. Even as the evacuation saved countless Soviet Jews from almost certain death, it spawned a new and virulent wave of anti-Semitism. This magisterial work is the first in-depth study of this crucial but neglected episode in the history of twentieth-century population displacement, World War II, and the Soviet Union.

It was very difficult for a poor person to gain wealth. The only way to get property was to already have some, and occupations from which a person could get rich were closed to those of lower social standing. Basically, if you were born poor you staid poor. To get ahead, or even meet basic needs in some cases, you would have to rob.
I would argue that in addition to class inequities, Moll Flanders is a story of the inequities between men and women. Women did not have the right to own property, so the only way a woman could gain wealth or social standing was to marry a man who had it. A woman could also not marry if she was not pure, yet many men took advantage of young women who were either servants or otherwise poor, as in Moll's case. A man who had a relationship with a woman "ruined" her and ended her hopes of ever being raised in social class. Moll has this problem, of course. For example, when Moll has to get her husband drunk so he won't realize she is not a virgin.

CFD Novice to Expert Part 4: CFD 101
Great to see that you are sticking with the series. After the previous article "CFD Novice to Expert Part 3: Fluid Dynamics 201" you are now rapidly approaching halfway, with this being part 4 of this 7 part series.
I know - you thought this was going to be a course in CFD. Now with a base of fluid dynamics knowledge, you are ready for the juicy CFD part. As a point of reference, the Reynolds-Averaged Navier-Stokes (RANS) formulation of the governing flow equations is the most popular and practical approach to CFD for typical engineering flows with the current generation of computing resources - this is worth bearing in mind as you progress through the references presented in this section. First stop for a gentle definition and introduction to CFD is the Computational Fluid Dynamics article at Wikipedia. If you prefer your knowledge delivered by video, then try the free Boston University Introduction to CFD on iTunes.
Hopefully you come away from these introductions with an appreciation of key CFD concepts, such as geometry, meshing, material (physical) properties, boundary conditions, numerical schemes, turbulence modeling, accuracy, and flow visualization. If not, then try the more complicated but forthright descriptions in the CFD Online Wiki Reference section.

School security assessments are an invaluable tool to improve school security, school climate and school emergency preparedness. While there are some instances where school officials have no choice to do otherwise, school security assessments conducted when schools are closed are less effective. School security assessments are more effective when they are conducted when assessors can observe students and employees arriving in the morning, departing in the afternoon and moving about the school during the school day.
Having assisted in school security assessments for more than 5,000 public and non-public schools over the years, our analysts have all noted that they have more findings when assessments are conducted when schools are in session. For example, one of the most important aspects of a school security assessment involves the evaluation of student supervision. Improving student supervision helps to reduce the risk of violence, student abductions, arson, vandalism, accidental injury and a range of other crisis situations. Good student supervision also helps school employees more rapidly and effectively shelter students from a gunman, a tornado or a hazardous materials incident.
Schools should try to avoid conducting school security assessments when schools are closed even if this means delaying them until the next school year. This is especially true if major changes such as implementation of new school security technologies will be guided by the school security assessment process. Whether your school organization is an independent school or a large public school system, school security assessments conducted during the school year will yield more useful information and thus value.

Saturn, the sixth planet from the Sun and the second-largest in our solar system, has the most spectacular and complex ring system. Earth may soon have its own set of rings, according to researchers at the University of Utah, US. These rings which may develop around our planet, however, will be made up of space debris. This comes as no surprise with the rising number of defunct satellites and growing anti-satellite tests, including the latest one by Russia.
There are currently 170 million pieces of space junk in orbit around the Earth, according to the European Space Agency (ESA). Most of these are small, but some are large enough to threaten space flights and orbital missions. Space junk, considered a type of pollution, has grown dramatically in the past decades — by about 7,500 metric tonnes.
“Earth is on course to have its own rings,” Jake Abbott, a professor of robotics at the University of Utah, told The Salt Lake Tribune. “They’ll just be made of junk,” he added. Abbott has worked with magnets for years. He and his team of engineers are now working to find ways to clean up the space junk, using magnets.
The researchers say they have figured out how to rapidly spin magnets and manipulate the objects at the centre using magnetic fields, even if they are not made up of magnetic metal — such as space debris. They tested their research by moving a copper ball on a plastic raft in a tank of water. The magnets moved the sphere not only in a square but also rotated the ball.
The researchers say the technology can be used one day to make robots move the junk into a decaying orbit or move it away into space without even having to physically touch it.
The research has been published in a recent article in the Nature journal. Abbott says it is just a question of engineering now: building and launching the technology to create Earth’s own rings.
