  • 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)

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.

    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

  • I have always talked to my cats. I say their name when I see them, when I pet them and when I feed them. They know their names and come when called. The human voice is calming to a cat. Some cats will respond when talked to, others just look at me, but at least I have their attention. I've had other cats that would answer every question with different sounds. Since I don't speak "cat" it was impossible to understand, though. Cats can remember us by our voices as well. One of our cats named "Graceful Mowser" was sold to some friends of ours and a year and a half later had kittens. They called her "Mouse". We were invited to see the kittens, but the momma kept standing over them so we couldn't see them. I talked to her, "Hi Gracie, what beautiful babies" and she stood back as if she was proud and looked at me intently. I always called her "Gracie". When other people came to see the kittens she still tried to cover them. Later, whenever we stopped by, Gracie would come to greet us as soon as she heard my voice. Otherwise she was naturally shy and would hide whenever anyone came in the house.

  • 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.

  • 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.

The study established a positive association between an increased risk of explains health outcome measures at various distances from storm drains. For example, the study found a 1-in-14 chance of fever for swimmers in front of the drain versus a 1-in-22 chance at 400 or more yards away.

  • The three primaryactivities used in these programs include efforts to characterizestorm water runoff; BMPs aimed at reducing pollutants in stormwater runoff to the maximum extent practicable; and reportingprogram activities, monitoring results, and costs of implementingthe program.

  • Several officials in the cities we visited said that their annualcosts are likely to increase. A number of factors could affectthe costs. For example, a Baltimore City official explained thatthe anticipated, future program costs depend on several factors,including (1) requirements in watershed- management planscurrently being developed, (2) pollution-reduction goals the citywill be required to achieve, (3) requirements of the stateregulatory agency in future permits, and (4) requirements thecity may have to meet if TMDLs or numeric effluent limits areincorporated into NPDES storm water permits. Other city officialsalso expressed concern about the extent to which TMDLs couldaffect their future costs. These city officials are concernedthat when and if TMDLs are established, their future storm waterpermits may require that storm water runoff meet specific waterquality standards. For example, Los Angeles County's trash TMDLcould potentially drive the county's storm water management costsupward, and the county expects additional TMDLs to be imposed. Onthe other hand, Worcester officials estimated that their futurestorm water costs would be about the same as they were at thetime of our review-about $4.5 million per year.

  • The health benefits of pet ownership are obvious for people who like animals, and most of us doat on friendly, clean, non-threatening animals. Dogs and cats are generally more affectionate and entertaining as pets than, say, fish or birds or ferrets, though many delight in those animals, too.
  • Besides that, a pet gives you something to care for and thus provides some structure for your life.

  • Without an accurate assessment of the extent of the remaining oil, subsistence food-gatherers, consumers of commercial fish products from the area, and tourists have used mostly anecdotal evidence as the basis for economic decisions regarding resource utilization in the affected area.
  • Consequently, the Auke Bay Laboratory (ABL) with funding from the EVOS Trustee Council, took on the task of assessing the remaining oil along the shorelines of Prince William Sound during the summer of 2001
  • The primary objective of the project was to measure the amount of oil remaining in the intertidal zone of Prince William Sound.  Secondary objectives include determining the rate of decline of oil on these beaches, estimating the persistence of the remaining oil, and correlating the remaining oil with geomorphological features.
  • heavily and moderately oiled
  • The 2001 survey adopted a stratified random/adaptive sampling (SRAS) design. Two random pits were excavated to a depth of 0.5 m (1.6 feet) in every stratified block (0.5-m verticle drop in tide height) within a grid system established at each site. If subsurface oil was discovered in any of the randomly stratified origin pits, then additional adaptive pits were excavated above, below, to the right, and to the left of the origin pit until the extent of the oil patch was determined.
  • Buried or subsurface oil is of greater concern than surface oil.
  • Subsurface oil can remain dormant for many years before being dispersed and is more liquid, still toxic, and may become biologically available.
  • A disturbance event such as burrowing animals or a severe storm reworks the beach and can reintroduce unweathered oil into the water.
  • The toxic components of this type of surface oil are not as readily available to biota, although some softer forms do cause sheens in tide pools.
  • 1) Surface oil was determined to be not a good indicator of subsurface oil. 2) Twenty subsurface pits were classified as heavily oiled.  Oil saturated all of the interstitial spaces and was extremely repugnant. These “worst case” pits exhibited an oil mixture that resembled oil encountered in 1989 a few weeks after the spill - highly odiferous, lightly weathered, and very fluid. 3) Subsurface oil was also found at a lower tide height than expected (between 0 and 6 feet), in contrast to the surface oil, which was found mostly at the highest levels of the beach (Table 3).  This is significant, because the pits with the most oil were found low in the intertidal zone, closest to the zone of biological production, and indicate that our estimates are conservative at best.

  • 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.

  • Ader kept working to perfect his airplane, and finally, with the financial backing of the French Army, he built Avion III, a flying machine similar in design to the Eole but with a longer wingspan and two four-blade propellers. On Oct. 14, 1897, Ader tested his Avion at Satory with a military observer team present. Ader claimed that that day he had again flown, but three witnesses disagreed with each other about whether Ader actually took off and flew the Avion before it crashed.

  • In 1898, at President William McKinley's instigation, the U.S. Army awarded Langley $50,000 to develop a plane that would carry a man aloft. In December, 1903, nine days before the Wrights' test at Kitty Hawk, Langley tried out his new gasoline-powered experimental model. A mishap with the catapult caused the airplane to plunge to the bottom of the Potomac, and Langley gave up his experiments after being criticized by the press for the great expense to the taxpayers.

  • Feral cats can minimize rodent problems. While cats cannot hunt rats and mice into extinction, they can keep their populations in check and discourage new rodents from moving into the area. Often feral cats fill in a gap in the current ecosystem. For example bob cats or lynx used to live up and down the East Coast but were hunted ruthlessly and driven away by development. Feral cats are similar in size and behavior to these native feline predators and help to control the same species of small prey animals. Many people enjoy watching feral cats and observing animals has been shown to lower blood pressure in medical studies. People who help to care for feral cats by feeding them and taking them to the vet enjoy many benefits. Often cat caretakers are elderly and live alone, a population at risk for depression, loneliness, and isolation. Cats relieve these conditions and often bring a sense of happiness and purpose to people who help them. Just as companion animals have been shown extend life expectancies, lower blood pressure, and relieve stress, caring for feral cats improves the health of their caretakers. Individuals who cannot take on the full time commitment of adopting a companion animal can participate in programs to help feral cats. This provides a viable alternative to irresponsibly purchasing an animal one is not prepared to care for. An established, stable, vaccinated, and sterilized colony of feral cats will deter other stray and feral cats from moving into the area. This actually decreases the risk that residents will encounter an unvaccinated cat, and will virtually eliminate problem behaviors like fighting and spraying.

Outrage at 'starvation' of a stray dog for art | Art and design | The Observer - 0 views

  • Chaining up a dog and forcing it to go without food and water in the name of art is a surefire way of making yourself unpopular with animal lovers. The furore created by Damien Hirst's pickled sheep and Tracey Emin's dirty bed pales into insignificance against the international outrage Guillermo 'Habacuc' Vargas has unleashed. The Costa Rican has been called an animal abuser, killer and worse over claims that a stray dog called Natividad died of starvation after he displayed it at an exhibition last year at the Códice Gallery in Managua, Nicaragua. Vargas tethered the animal without food and water under the words 'Eres Lo Que Lees' - 'You Are What You Read' - made out of dog biscuits while he played the Sandinista anthem backwards and set 175 pieces of crack cocaine alight in a massive incense burner. More than a million people have signed an online petition urging organisers of this year's event to stop Vargas taking part. Vargas, 32, said he wanted to test the public's reaction, and insisted none of the exhibition visitors intervened to stop the animal's suffering. He refused to say whether the animal had survived the show, but said he had received dozens of death threats. Juanita Bermúdez, director of the Códice Gallery, insisted Natividad escaped after just one day. She said: 'It was untied all the time except for the three hours the exhibition lasted and it was fed regularly with dog food Habacuc himself brought in.'

Thanksgiving - 0 views

  • The history of Thanksgiving goes much further back than Plymouth and 1621. In fact, people across the world from every culture have been celebrating and giving thanks for thousands of years. In this country, long before English colonists arrived, Native People celebrated many different days of thanksgiving. “Strawberry Thanksgiving” and “Green Corn Thanksgiving” are just two of kinds of celebrations for the Wampanoag and other Native People. In 1621, the English colonists at Plymouth (some people call them “Pilgrims” today) had a three-day feast to celebrate their first harvest. More than 90 native Wampanoag People joined the 50 English colonists in the festivities. Historians don­t know for sure why the Wampanoag joined the gathering or what activities went on for those three days. Form the one short paragraph that was written about the celebration at the time, we know that they ate, drank, and played games. Back in England, English people celebrated the harvest by feasting and playing games in much the same way. The English did not call the 1621 event a “thanksgiving.” A day of “thanksgiving” was very different for the colonists. It was a day of prayer to thank God when something really good happened. The English actually had their first thanksgiving in the summer of 1623. On this day they gave thanks for the rain that ended a long drought.

  • Cat ownership helps children to learn responsibility and develop a greater capacity for empathy at an early age. In addition, pets provide unconditional love and acceptance, which can help children through difficult times.
  • Cats also offer protection against certain physical conditions. If adopted before or shortly after a child is born, owning a cat reduces the risk of developing animal allergies, asthma, and possibly other illnesses as well. One study found that children living with pets were 13-18% less likely to miss school due to illness than children without pets. Researchers who measured the salivary immunologobulin levels of young pet owners found that their immune function was less likely to be in the sub-normal range than that of non-pet-owners. Additionally, cats can provide particular therapeutic benefits for children with conditions such as autism, especially those who suffer from motor coordination problems.

braille blind dots system

  • Born on January 4, 1809, Coupvray, France, Braille was accidentally blinded in one eye at the age of three. Within two years, a disease in his other eye left him completely blind.
  • Captain Charles Barbier invented sonography, or nightwriting, a system of embossed symbols used by soldiers to communicate silently at night on the battlefield. Inspired by a lecture Barbier gave at the Institute a few years later, the fifteen-year-old Braille adapted Barbier's system to replace Haüy's awkward embossed type, which he and his classmates had been obliged to learn.
  • In his initial study, Braille had experimented with geometric shapes cut from leather as well as with nails and tacks hammered into boards. He finally settled on a fingertip-sized six-dot code, based on the twenty-five letters of the alphabet, which could be recognized with a single contact of one digit. By varying the number and placement of dots, he coded letters, punctuation, numbers, diphthongs, familiar words, scientific symbols, mathematical and musical notation, and capitalization. With the right hand, the reader touched individual dots and, with the left, moved on toward the next line, comprehending as smoothly and rapidly as sighted readers. Using the Braille system, students were also able to take notes and write themes by punching dots into paper with a pointed stylus which was aligned with a metal guide.

  • Many of us celebrate Thanksgiving and just assume since we do that everyone else does as well. The answer to whether Thanksgiving is celebrated nationally or not is that it is. Most families celebrate Thanksgiving each and every year and individuals from all over the country make plans to eat turkey and give thanks. Thanksgiving is a nationally recognized holiday. Kids dont go to school, most businesses arent open, and politics are briefly put on hold. The most important Thanksgiving activities include eating, watching sports, and spending time with family and friends. No matter where you are in the nation you will find that most people celebrate Thanksgiving pretty much the same. Some families will celebrate at lunchtime and others at dinner and still others may go out to dinner or not celebrate at all. But, for the most part, celebrating Thanksgiving is an American tradition and one that all Americans enjoy taking part in. Parades Around the Country Even if you cant travel the entire country to see how Thanksgiving is celebrated you can get a pretty good idea. There are Thanksgiving Day parades all over the country and many of them are televised. One of the most popular and well known parades is the Macys Thanksgiving Day Parade. This parade has been around for decades and continues to be a hit with New Yorkers as well as individuals around the country who make watching the parade on television part of their celebration. You may choose to attend a parade on Thanksgiving day in your town or perhaps you will choose to watch one on TV. Regardless, parades around the country really make up part of the Thanksgiving culture we have all become so accustomed to. In fact, when you turn the television on Thanksgiving Day you will more than likely see a parade or a football game! Thats just part of Thanksgiving Day culture in our country.
