  • end of the spectrum are the reds and oranges. These gradually shade into yellow, green, blue, indigo and violet. The colors have different wavelengths, frequencies, and energies. Violet has the shortest wavelength in the visible spectrum. That means it has the highest frequency and energy. Red has the longest wavelength, and lowest frequency and energy. LIGHT IN THE AIR Light travels through space in a straight line as long as nothing disturbs it. As light moves through the atmosphere, it continues to go straight until it bumps into a bit of dust or a gas molecule. Then what happens to the light depends on its wave length and the size of the thing it hits. Dust particles and water droplets are much larger than the wavelength of visible light. When light hits these large particles, it gets reflected, or bounced off, in different directions. The different colors of light are all reflected by the particle in the same way. The reflected light appears white because it still contains all of the same colors. Gas molecules are smaller than the wavelength of visible light. If light bumps into them, it acts differently. When light hits a gas molecule, some of it may get absorbed. After awhile, the molecule radiates (releases, or gives off) the light in a different direction. The color that is radiated is the same color that was absorbed. The different colors of light are affected differently. All of the co

  • THE BLACK SKY AND WHITE SUN On Earth, the sun appears yellow. If you were out in space, or on the moon, the sun would look white. In space, there is no atmosphere to scatter the sun's light. On Earth, some of the shorter wavelength light (the blues and violets) are removed from the direct rays of the sun by scattering. The remaining colors together appear yellow. Also, out in space, the sky looks dark and black, instead of blue. This is because there is no atmosphere. There is no scattered light to reach your eyes. WHY IS THE SUNSET RED? As the sun begins to set, the light must travel farther through the atmosphere before it gets to you. More of the light is reflected and scattered. As less reaches you directly, the sun appears less
  • The sky around the setting sun may take on many colors. The most spectacular shows occur when the air contains many small particles of dust or water. These particles reflect light in all directions. Then, as some of the light heads towards you, different amounts of the shorter wavelength colors are scattered out. You see the longer wavelengths, and the sky appears red, pink or orange.
  • RE ABOUT:THE ATMOSPHERE WHAT IS THE ATMOSPHERE? The atmosphere is the mixture of gases and other materials that surround the Earth in a thin, mostly transparent shell. It is held in place by the Earth's gravity. The main components are nitrogen (78.09%), oxygen (20.95%), argon (0.93%), and carbon dioxide (0.03%). The atmosphere also contains small amounts, or traces, of water (in local concentrations ranging from 0% to 4%), solid particles, neon, helium, methane, krypton, hydrogen, xenon and ozone. The study of the atmosphere is called meteorology. Life on Earth would not be possible without the atmosphere.
  • d increases with increasing altitude. The increase is caused by the absorption of UV radiation by the oxygen and ozone. · The temperature increase with altitude results in a layering effect. It creates a global "inversion layer", and reduces vertical convection. Mesosphere - Extends out to about 100 km (65 miles) · Temperature decreases rapidly with increasing altitude. Thermosphere - Extends out to about 400 km ( 250 miles)
  • hes the Earth, 30% is reflected back into space by clouds and the Earth's surface. The atmosphere absorbs 19%. Only 51% is absorbed by the Earth's surface. We are not normally aware of it but air does have weight. The column of air above us exerts pressure on us. This pressure at sea level is defined as one atmosphere. Other equivalent measurements you may hear used are 1,013 millibars, 760 mm Hg (mercury), 29.92 inches of Hg, or 14.7 pounds/square inch (psi). Atmospheric pressure decreases rapidly with height. Pressure drops by a factor of 10 for every 16 km (10 miles) increase in altitude. This means that the pressure is 1 atmosphere at sea level, but 0.1 atmosphere at 16 km and only 0.01 atmosphere at 32 km. The density of the lower atmosphere is about 1 kg/cubic meter (1 oz./cubic foot). There are approximately 300 billion billion (3 x 10**20, or a 3 followed by 20 zeros) molecules per cubic inch (16.4 cubic ce

The density of air also decreases rapidly with altitude. At 3 km (2 miles) air density has decreased by 30%. People who normally live closer to sea level experience temporary breathing difficulties when traveling to these altitudes. The highest permanent human settlements are at about 4 km (3 miles). LAYERS OF THE ATMOSPHERE The atmosphere is divided into layers based on temperature, composition and electrical properties. These layers are approximate and the boundaries vary, depending on the seasons and latitude. (The boundaries also depend on which "authority" is defining them.) LAYERS BASED ON COMPOSITION Homosphere

  • ORIGIN OF THE CELEBRATION Section: Festival The start of the New Year has been celebrated in China for more than 3,000 years. New Year was a time when the farmers gave thanks for the harvest and prayed to the gods for a good harvest in the coming year. This was the one period in the busy farming year when there was time to have a celebration and when the family could get together, relax, and be merry. Chinese New Year begins with a New Moon. The Lunar Year is calculated from the time it takes for the Moon to travel around the Earth, while the Western (Gregorian) calendar is based on the time it takes for the Earth to circle the Sun. The orbits of the Moon bear no relation to the time it takes for the Earth to go around the Sun, which is why the Chinese Lunar New Year is celebrated on a different date each year. In China the New Year was renamed the Spring Festival, in 1911, when the Western calendar was officially accepted in China. However, it is still commonly known around the world as the Chinese New Year. Chinese years are named after one of twelve animals. These have been used in the same order to name the years since the sixth century A.D. Each animal is said to have its own personality and emotions, which are present in people born within its year. ~~~~~~~~By Sarah Moyse This article is copyrighted. All rights reserved.Source: Chinese New Year (0-7613-0374-X)
  • RELIGIONS AND RITUALS Section: Festival Although the New Year celebration is not mainly a religious one, many Chinese will visit a temple at this time of the year to make an offering to the Buddha or to the gods in the hope of making the New Year a good one. Ancestors and gods are honored with ceremonies in the home around a family altar decorated with flowers. Incense and candles are burned at the altar. At important family banquets the ancestors may be recognized as "spiritual guests" and first offered food that is afterward eaten with the meal. The Chinese have three main systems of ideas that are important to them: Confucianism, Daoism, and Buddhism. Although these systems are very different, many Chinese follow some or all of the rituals associated with them just to be safe. Confucius lived in the fifth century B.C. and spoke about the value of good behavior in private life and in government. He said that politeness, honesty, courage, and loyalty were what made good people. He believed in self-development through education and thought that people gain in wisdom as they grow older. It is part of the Confucian tradition to honor parents and ancestors.
  • Daoism comes from the teachings of Laozi, who lived at the same time as Confucius. His book, the Dao De Jing (The Way and Its Power), describes the way (dao means "way") to live at peace with nature so as not to upset natural balances. The Way involves balance between opposite forces. They are called yin and yang. While yin is dark and female, yang is the opposite, being light and male. When yin and yang are balanced, there is perfect harmony with nature. Unlike Confucianism and Daoism, which started in China, Buddhism came from India and is based on the teachings of the Buddha -- a holy man. Buddha taught that people need to let go of earthly desires and become fully aware of what they are doing in the present. Buddhists believe that after death each soul moves on to another body, which may be animal or human. What one is chosen for in the next life depends on how good or bad the person has been in this life. The Chinese also pray to other gods, holding the view that the more gods who can look after them the better. The important ones are the Kitchen God, who watches the family in the home, the Jade Emperor, who is the most important god in heaven, the God of Wealth, who determines how wealthy people are, and the Door Gods. ~~~~~~~~By Sarah Moyse This article is copyrighted.

  • HOLIDAY CELEBRATIONS On New Year's Eve, Chinese families have a special feast of seafood and dumplings. Dessert is always Nian Gao- a special New Year's Cake. Everyone stays up late to watch the midnight fireworks. On New Year's Day families go door to door to visit. They exchange gifts with their relatives and neighbors. It is thought to be bad luck to fight or argue at the start of a New Year. Everyone is warm and friendly toward each other. Fireworks light the night sky during a New Year celebration in Hong Kong. ~~~~~~~~By Kieran Walsh Kieran Walsh is a winter of children's nonfiction books, primarily on historical and social studies topics.

The dope on steroids: Why some athletes take the risk : UMNews : University of Minnesota - 0 views

shared by anonymous on 03 Dec 08 - Cached
  • The stakes in Athens are fierce. The difference between an Olympic gold or silver medal could be a one hundredth of a second on the track or in the pool; an inch on the pole vault or shot put.
  • The athletes who make the Olympic cut are blessed with the right combination of physical and psychological traits, including an intense competitive drive and an unrelenting determination to be the best. This is the stuff of champions.
  • Steroids are not just for elite athletes--they can be used by anyone who wants to change his or her body image. The Centers for Disease Control's Youth Risk Behavior Surveillance report shows more than a million youth taking steroids, and the numbers have been rising every year.
  • ...13 more annotations...
  • Unfortunately, sometimes so are steroids. For decades, athletes have used anabolic (meaning muscle-building) steroids and other performance-enhancing drugs to build strength and endurance. And those drugs are getting more and more sophisticated in an effort to evade detection. Doping, as the practice is called, is illegal and, by most people's standards, unethical. Athletes who have been caught using these drugs have been stripped of their Olympic medals and world records and banned from their sports, sometimes for years, and on occasions for a lifetime.
  • "There are rights and wrongs in life, and if it's against the rules, it's cheating to do it," says Wiese-Bjornstal. "I love sports, but some athletes treat elite sports as if they are life itself, more important than their health, their loved ones, and even their lives."
  • In addition, steroids mess with your body. Potential side effects include high blood pressure, strokes, nausea, sleep problems, increased aggressiveness, and severe mood swings. In men, steroids can reduce sperm count and cause impotence, breast growth, and shrunken testicles. In women, side effects can include reduced breast size, increased body and facial hair, a deepened voice, and menstrual problems.
  • With the risks and consequences of steroid use so high, why do some athletes continue to dope?
  • "The major underlying factor [with steroids use] is that winning at all costs is the most important thing," says Diane Wiese-Bjornstal, associate professor in the School of Kinesiology.
  • She says that athletes that use steroids often have the mindset that "they are demonstrating that they are as highly committed to their sport as they can be and are doing whatever it takes to prove to themselves, their coaches, and to the world that they are true athletes who will do anything to win."

      Diane Wiese-Bjornstal's Comment
  • From a moral and ethical framework, Wiese-Bjornstal believes this is twisted thinking. "There are rights and wrongs in life, and if it's against the rules, it's cheating to do it," she says. "I love sports, but some athletes treat elite sports as if they are life itself, more important than their health, their loved ones, and even their lives."

      Wiese-Bjornstal's Comment
  • She also says there is pressure to dope because of the belief that everyone else is doing it, and that if an athlete wants to compete at the highest level, she or he has to do it, too.
  • Nancy Cullen, a sports psychology consultant for the University, says the temptation to use steroids and other performance-enhancing drugs simply comes down to the rigors and pressure of elite competition and the desire to win. She cites an alarming poll taken in 1995 of 198 sprinters, swimmers, power lifters and others, most of whom were Olympians or aspiring Olympians. The poll asked if the athletes would take a banned performance-enhancing substance if they knew if would help them win and they wouldn't be caught--195 responded, yes.
  • Most athletes train for perfection," says Cullen. "The drive to achieve and win is so strong. If the difference between winning or losing is a hundredth of a second, and there is a drug that might give you the edge, the temptation can be great."
  • For some Olympic events, steroid scandals have cast a pall over the games, leaving viewers to wonder after each win, "Did he take drugs? Did she?"
  • Both Wiese-Bjornstal and Cullen agree that education, beginning with young athletes, is important in the fight against steroid use, as are drug testing and stiffer penalties for those who are caught. They also believe that coaches and parents play an important role in supporting the healthy ambitions of developing athletes.
  • "It's important to teach athletes to know what the consequences are and to learn other training practices that are legal and don't involve taking drugs," says Cullen. "Strive to win, strive for perfection, but do it within the rules of the game."

shared by Bibin John on 03 Dec 08 - Cached
  • An aircraft is a vehicle which is able to fly through the Earth's atmosphere or through any other atmosphere. Rocket vehicles are not aircraft if they are not supported by the surrounding air. All the human activity which surrounds aircraft is called aviation.
  • Heavier-than-air aircraft must find some way to push air or gas downwards, so that a reaction occurs (by Newton's laws of motion) to push the aircraft upwards. This dynamic movement through the air is the origin of the term aerodyne. There are two ways to produce dynamic upthrust: aerodynamic lift, and powered lift in the form of engine thrust. Aerodynamic lift is the most common, with aeroplanes being kept in the air by the forward movement of wings, and rotorcraft by spinning wing-shaped rotors sometimes called rotary wings. A wing is a flat, horizontal surface, usually shaped in cross-section as an aerofoil. To fly, the wing must move forwards through the air; this movement of air over the aerofoil shape deflects air downward to create an equal and opposite upward force, called lift, according to Newton's third law of motion. A flexible wing is a wing made of fabric or thin sheet material, often stretched over a rigid frame. A kite is tethered to the ground and relies on the speed of the wind over its wings, which may be flexible or rigid, fixed or rotary. With powered lift, the aircraft directs its engine thrust vertically downwards. The initialism VTOL (vertical take off and landing) is applied to aircraft that can take off and land vertically. Most are rotorcraft. Others, such as the Hawker Siddeley Harrier, take off and land vertically using powered lift and transfer to aerodynamic lift in steady flight. Similarly, STOL stands for short take off and landing. Some VTOL aircraft often operate in a short take off/vertical landing regime known as STOVL. A pure rocket is not usually regarded as an aerodyne, because it does not depend on the air for its lift (and can even fly into space), however many aerodynamic lift vehicles have been powered or assisted by rocket motors. Rocket-powered missiles which obtain aerodynamic lift at very high speed due to airflow over their bodies, are a marginal case.

Includes the important class of delta wings. Location of the horizontal stabiliser, if any. Dihedral angle - positive, zero or negative (anhedral). A variable geometry aircraft can change its wing configuration during flight. A flying wing has no fuselage, though it may have small blisters or pods. The opposite of this is a lifting body which has no wings, though it may have small stabilising and control surfaces.

  • Depending on the species, bats can be gray, brown, white or reddish brown.
  • Bats have teeth and chew their food. Seventy percent of all bats eat insects. One bat can eat more than a thousand insects in one hour!
  • The largest bats have a wingspan of more than six feet. However, most are smaller.
  • Many people do not like bats and are afraid of them because they think all bats have rabies. Rabies is a virus that is transmitted to animals and people through animal bites. A study by the University of Florida has shown less than one-half of 1 percent of all bats have rabies. It is more likely for a person to be bitten by an unvaccinated dog or cat.
  • People also think vampire bats will try to attack humans. That is simply not true.
  • Bats are not a danger to people and are actually quite valuable. Very few carry rabies, and they help to control the insect population. They also help seed new plants and pollinate our crops!

However, it is still commonly known around the world as the Chinese New Year. Chinese years are named after one of twelve animals. These have been used in the same order to name the years since the sixth century A.D. Each animal is said to have its own personality and emotions, which are present in people born within its year. ~~~~~~~~By Sarah Moyse This article is copyrighted.

  • Holidays are very important to the French. The French begin the year with a celebration of the Jour de l'An, which is New Year's Day. They greet each other by saying "Bonne Annee!" (Happy New Year). On January 6th there is la Fete des Rois (the Festival of the Three Kings), where people have a King's Cake. Whoever finds the special toy that has been baked into the cake gets to be king or queen for the day. In February, the French celebrate la Saint-Valentin or Valentine's Day by giving, valentines and chocolates. Also the French mark the start of Lent (a religious time when people fast) with Mardi Gras celebrations. On the 1st of April people play tricks on each other and say "Poisson d'avril!" which means "April fish!" People have little paper fishes that they cut out and try to stick on the backs of their friends that day. Easter is an important holiday in France. On the morning of Easter Sunday, most French people go to church. Afterwards, they carry home candles that have been blessed by priests. For Easter, which is called Le Pacques, omelettes, (an egg dish) are usually eaten for breakfast. People also give each other chocolate eggs and chocolate bunnies.

During the summer months, there is the Tour de France, which is a bicycle race. The 14th of July is France's Independence Day, called Bastille Day. There are parades and fireworks, and people decorate their houses and celebrate all day. Christmas is a favorite holiday in France for the young and old. On Christmas Eve, families often attend midnight mass. After church, they return home for a big dinner called le reveillon. Dinner often consists of such foods like soup, turkey, goose, and oysters. A popular dessert at Christmas time is buche de Noel, a cake filled with chocolate and rolled into the shape of a log. The cake represents the Yule log that burns in the fireplaces of the French people during Christmas.

  • ?Eres lo que lees?. You are what you read. The sentence, written with dog food, was displayed on the white wall of an art gallery. Close to that wall, an abandoned and diseased street dog was left tied to a rope and a wire string. An incense burner was placed nearby where, allegedly, crack and cannabis was burnt during the inauguration. Without food and water, the animal died in the gallery during the next day.It happened in Nicaragua. It was an ?installation? by artist Guillermo Vargas, known as Habacuc.The situation, documented with several images, received a lot of attention on the web and originated an online petition against it?s author that gathers, as I write these words, close to 50.000 signatures.

  • Thanksgiving Feast of 1621, but few realize that it was not the first festival of its kind in North America. Long before Europeans set foot in the Americas, native peoples sought to insure a good harvest with dances and rituals such as the Green Corn Dance of the Cherokees.
  • The first Thanksgiving service known to be held by Europeans in North America occurred on May 27, 1578 in Newfoundland, although earlier Church-type services were probably held by Spaniards in La Florida. However, for British New England, some historians believe that the Popham Colony in Maine conducted a Thanksgiving service in 1607 (see Sources: Greif, 208-209; Gould, and Hatch). In the same year, Jamestown colonists gave thanks for their safe arrival, and another service was held in 1610 when a supply ship arrived after a harsh winter. Berkley Hundred settlers held a Thanksgiving service in accordance with their charter which stated that the day of their arrival in Virginia should be observed yearly as a day of Thanksgiving, but within a few years an Indian uprising ended further services (Dabney). Thus British colonists held several Thanksgiving services in America before the Pilgrim's celebration in 1621.
  • In 1623, the Pilgrims at Plymouth Plantation, Massachusetts, held another day of Thanksgiving. As a drought was destroying their crops, colonists prayed and fasted for relief; the rains came a few days later. And not long after, Captain Miles Standish arrived with staples and news that a Dutch supply ship was on its way. Because of all this good fortune, colonists held a day of Thanksgiving and prayer on June 30. This 1623 festival appears to have been the origin of our Thanksgiving Day because it combined a religious and social celebration.

  • estivals of Thanksgiving were observed sporadically on a local level for more than 150 years. They tended to be autumn harvest celebrations. But in 1789, Elias Boudinot, Massachusetts, member of the House of Representatives, moved that a day of Thanksgiving be held to thank God for giving the American people the opportunity to create a Constitution to preserve their hard won freedoms. A Congressional Joint Committee approved the motion, and informed President George Washington. On October 3, 1789, the President proclaimed that the people of the United States observe "a day of public thanksgiving and prayer" on Thursday, the 26th of November. The next three Presidents proclaimed, at most, two days of thanksgiving sometime during their terms of office, either on their own initiative or at the request of a joint Resolution of Congress. One exception was Thomas Jefferson, who believed it was a conflict of church and state to require the American people hold a day of prayer and thanksgiving. President James Madison proclaimed a day of Thanksgiving to be held on April 13, 1815, the last such proclamation issued by a President until Abraham Lincoln did so in 1862.
  • Thanksgiving holiday may be given to Sarah Josepha Hale. Editor of Ladies Magazine and Godey's Lady's Book, she began to agitate for such a day in 1827 by printing articles in the magazines. She also published stories and recipes, and wrote scores of letters to governors, senators, and presidents. After 36 years of crusading, she won her battle. On October 3, 1863, buoyed by the Union victory at Gettysburg, President Lincoln proclaimed that November 26, would be a national Thanksgiving Day, to be observed every year on the fourth Thursday of November. Only twice has a president changed the day of observation. President Franklin D. Roosevelt, in order to give depression-era merchants more selling days before Christmas, assigned the third Thursday to be Thanksgiving Day in 1939 and 1940. But he was met with popular resistance, largely because the change required rescheduling Thanksgiving Day events such as football games and parades. In 1941, a Congressional Joint Resolution officially set the fourth Thursday of November as a national holiday for Thanksgiving.

  • Cats are very important subjects in cancer research. Leukemia is perhaps the most infamous of the diseases shared by cats and people. In cats, it is caused by an AIDS-like retrovirus. A recently discovered vaccine against feline leukemia may act as a model for an AIDS vaccine. Mammary cancer is also common in the cat, and many features of feline mammary cancer resemble the human breast cancer which, among the human cancers, is the greatest killer of women.

  • The burakumin (people of the village) are ethnically the same as the majority of Japanese. However, their ancestors were members of the former outcast class. The burakumin are often treated unfairly.
  • Shinto is based on the worship of local spirits in nature.
  • Japan has a rich and complex culture. Native Japanese traditions have been mixed with cultural styles adapted from China and, later, from the West. Japanese culture and art emphasize understated simplicity, elegance, and grace. For example, the traditional Japanese tea ceremony, flower arranging, and garden design are highly stylized and refined. On the other hand, contemporary Japanese society fully embraces Western-style popular culture—influenced by television, motion pictures, and advertising.
  • modern Japanese writers include Soseki Natsume, Ryunosuke Akutagawa, Osamu Dazai, Jun'ichiro Tanizaki, and Yukio Mishima.
  • Poetry plays a central role in Japanese culture.
  • The carefully composed paintings used few brush strokes to suggest a scene in nature.
  • Japanese No plays are generally short, stylized, and heroic.
  • Today the martial arts are more important as competitive sports and as aids to physical and mental fitness.
  • The Japanese economy grew remarkably throughout the 1960s, '70s, and '80s.
  • Historical records, however, show that Japan was not united as one state until the late 4th or early 5th century AD. It was ruled by the Yamato dynasty.
  • Meanwhile, Japan was developing trade contacts with the outside world.
  • By the mid-19th century the Tokugawa shogunate was unable to keep European and United States traders away.
  • A new government was established under the young emperor Mutsuhito, who took the name of Meiji, meaning “enlightened government.”
  • Japan soon sought to build an empire. It successfully fought a war with China (1894–95) and with Russia (1904–05).
  • The Japanese government believed that expansion through military conquest would help the economy.
  • Under the terms of surrender, Japan had to give up all the territory it had acquired since 1895.
  • Japan rebuilt its ruined economy, using new technology in every major industry.

    Good for body Some of the studies show that owning a pet can have very real physical benefits for their owners. These include: * Pet owners have lower blood pressure. It has long been known that the act of stroking a pet can reduce blood pressure. But a study at the State University of New York at Buffalo found that the beneficial effects continue even when the pet is not present. The study, which looked at a group of stockbrokers with hypertension, concluded that just owning a pet can help lower blood pressure -and keep it lower, even in stressful settings. * Pet owners have lower blood cholesterol levels. A study of more than 5,400 people conducted by Australia's Baker Medical Research Institute found that pet owners had not only lower blood pressure, but also lower levels of blood cholesterol and triglycerides in comparison to the non-pet owners, reducing the risk of heart disease. * Pet owners have a higher survival rate after serious illness. Two studies have found that heart attack patients who owned the pets were significantly more likely to be alive a year after they were discharged from the hospital than those who didn't. What's more, a study conducted at City Hospital in New York found that the presence of a pet affected survival rate even more than having a spouse or friends. Patients in hospitals or nursing homes who have regular visits from their pets have shown to be more receptive to treatment. The need to care for their pet gives them reason to recover and the will to live. * Pet owners have fewer doctors' visits. Studies conducted by Cambridge University in England and at the University of California at Los Angeles have found that pet ownership corresponds to overall improved health and fewer medical care visits. A study of Medicare patients also found that seniors who own dogs go to the doctor less than those who do not. Even the most highly-stressed older dog owners in the study had 21 % fewer physician's visits than non-dog ow
