• Digestive System.

  The stomach, located in the upper abdomen just below the diaphragm, is a saclike structure with strong, muscular walls. The stomach can expand significantly to storeall the food from a meal for both mechanical and chemical processing. The stomach contracts about three times per minute, churning the food and mixing it with gastricjuice. This fluid, secreted by thousands of gastric glands in the lining of the stomach, consists of water, hydrochloric acid, an enzyme called pepsin, and mucin (the...

  Her sister, though comparatively but little removed by matrimony, being settled in London, only sixteen miles off, was much beyond her daily reach; and many along October and November evening must be struggled through at Hartfield, before Christmas brought the next visit from Isabella and her husband and their littlechildren to fill the house and give her pleasant society again. Highbury, the large and populous village almost amounting to a town, to which Hartfield, in spite of its separate...

• Jimmy Carter.

  B Election of 1976 Carter apparently decided as early as 1972, halfway through his four-year term as governor, that he would seek the presidency of the United States. Soon after the1972 election, his campaign manager drew up a detailed campaign strategy. Carter followed the plan closely, beginning an exhausting schedule of campaigning as soonas his gubernatorial term ended. When Carter formally announced in January 1975 that he was a candidate for president, he had almost no national reputation...

• Horse Racing.

  interested parties claim the same horse at the same price, lots are drawn to determine the winning offer. Knowledgeable owners and trainers may use claiming races toobtain, at bargain prices, horses whose former owners underestimated the potential of their animals. Two other types of contests are match races and walkovers. A match race pits only two horses, almost always that season’s most successful racers, in a head-to-headduel. A walkover occurs when only one horse has not been scratched (w...

• White House - geography.

  Each Thanksgiving, the pardoning of the turkey takes place in the Rose Garden. This ceremony of rescuing a turkey and sending it to a petting zoo began during HarryTruman’s term, although Abraham Lincoln is said to have set a precedent by sparing his son’s pet turkey from the oven. III INSIDE THE WHITE HOUSE A large complex is needed for the many activities that take place at the White House. The White House has 132 rooms, 4 dining rooms, 35 bathrooms, 8 staircases, 3elevators, a clinic, a den...

• Volcano.

  before eruption. Very violent explosive eruptions are called Plinian eruptions, after Roman naturalist Pliny the Elder. These eruptions can last for several hours to daysand eject a large amount of pyroclastic material. Some volcanoes can produce much more energetic eruptions that eject materials farther from the vents because oftheir andesitic and dacitic composition. Andesitic and dacitic lava is generally thicker than basaltic lava. Stiff lava generally produces more-explosive eruptions. B No...

• Folk Art I INTRODUCTION Carved Native American Figure This figure of a Native American trapper was carved from a single pine log (about 1850-1890).

  that young Native American women were taught to weave by Ursuline nuns. The overall spirit of French-Canadian folk art is colorful, happy, and, at the same time,devout. B Anglo-Canadian Folk Art The English tradition in the Maritime provinces is strong in the decoration of utilitarian objects, in graining, marbling, and incising, and in ship carvings (both figureheadsand stern-board decorations). The emigration to Canada of many New Englanders during and after the American Revolution led to int...

• Iceland - country.

  III PEOPLE Icelanders are one of the most homogenous peoples in the world. They are predominantly of Nordic origin, descendants of the hardy people who emigrated fromNorway to Iceland in the Middle Ages. There are also some Celtic influences from Irish and Scottish immigrants who arrived from the British Isles ( see Celts). The population of Iceland (2008 estimate) is 304,367. Numerous times in its history, Iceland has suffered major population losses due to epidemics, volcanic eruptions, and...

• Labor Unions in the United States - U.

  National Guard troops were used against the strikers, with the result that the strike was lost and the union that conducted it virtually destroyed. In 1894 a strike by theAmerican Railway Union against the Pullman Palace Car Company was defeated by an injunction issued under the Sherman Antitrust Act of 1890, which made acombination or contract in restraint of trade illegal. Thereafter employers used injunctions with increasing frequency and effectiveness as an antistrike weapon. See also Hours...

  blocks in the eastern suburbs and around railway stations elsewhere; and homes on large lots in the outer suburbs, especially those to the northwest. For publichousing, the state government built a number of high-rise apartment blocks in run-down inner suburbs after World War II (1939-1945). These housing projects weresoon deemed unsuccessful and were discontinued because they fostered crime and other social problems. More recently, public housing has taken the form of separateor semidetached ho...

• Television.

  A charge-coupled device (CCD) can be much smaller than a camera tube and is much more durable. As a result, cameras with CCDs are more compact and portablethan those using a camera tube. The image they create is less vulnerable to distortion and is therefore clearer. In a CCD, the light from a scene strikes an array ofphotodiodes arranged on a silicon chip. Photodiodes are devices that conduct electricity when they are struck by light; they send this electricity to tiny capacitors. Thecapacitors...

The estimated growth rate of the population in 2008 was 3.6 percent. The birth rate was 48 per 1,000people and the death rate 12 per 1,000. Th...

• Bosnia and Herzegovina - country.

  Serb military campaigns in 1992 and 1993 and Croat campaigns in 1993 and 1995 were aimed at expelling others from areas claimed by these groups. By the end ofthe war almost all non-Serbs had been expelled from Serb-claimed lands in eastern and northern Bosnia, and non-Croats from Croat-claimed lands in southwesternBosnia. In turn, most non-Muslims had left land under Muslim control in northwestern Bosnia. The largest cities had mixed populations in 1991, but the war and its aftermath made them a...

There are two kinds of metamorphosis, called incompleteand complete. Dragonflies, grasshoppers, and crickets are some insects that go through incomplete metamorphosis asthey grow up. The young insects are called nymphs or naiads. The young insect molts, or crawls out ofits exoskeleton, as it grows bigger. It grows a new, larger exoskeleton. Its body chan...

• Lamia

  reason would tell him that it is not safe enough to depend only on a career as a poet. He saw in himself the ability and didn't let count anything else what could speak against the life of poet. This alike attitude is seen in Lycius when he listens to Lamia not to invite Appolonius to the marriage, even though he had learned everything by Appolonius, had always listen to his advices and obeyed his words. It is as if Keats saw himself turning away from his reason, shutting it out from his dream-l...

• Ecosystem.

  work. The tiny bacteria and fungi feed upon the remains of the salmon. They break down the salmon intochemical nutrients. Nutrients from the salmon go into the soil. The roots of plants along the riverbank take up the nutrients. They use the nutrients to make food. Inthis way, nutrients get recycled back through the ecosystem. WHAT CAN HARM AN ECOSYSTEM? Any change in one living or nonliving part of an ecosystem can cause changes in other parts. Droughts,storms, and fires can change ecosystems....

• From Bulfinch's Mythology: Midas - anthology.

  Gordius, being made king, dedicated his wagon to the deity of the oracle, and tied it up in its place with a fast knot. This was the celebrated Gordian knot, which, in after times it was said, whoever should untie should become lord of all Asia. Many tried to untie it, but none succeeded, till Alexander the Great, in his career ofconquest, came to Phrygia. He tried his skill with as ill success as others, till growing impatient he drew his sword and cut the knot. When he afterwards succeeded i...

• Lenny Wilkens Takes All-Time Victory Record.

  Wilkens showed us that loyalty to one's work is necessary, that it never stops, and that only when such a commitment is made can something good come out of it.There are worse lessons to learn from a public figure.” Four days later Wilkens was denied again when the Hawks lost to the Portland Trail Blazers by 5 points before a relatively small crowd of 8,477 at the Omni.Atlanta's rally from a 17-point deficit in the third quarter fell just short.

• Killer Whale - biology.

  V REPRODUCTION Mating occurs more often among killer whales of different pods to avoid inbreeding within pods. About 16 to 18 months after mating, females give birth to a single calf.Newborn calves weigh about 200 kg (440 lb) and are about 2.5 m (8 ft) long. Mothers nurse their calf for 14 to 18 months, although mothers continue to be protectiveof their young long after the offspring have been weaned. Scientists do not know how long killer whales live in the wild. Scientists estimate that male...

As in 1869, they were worried about title to their river lots, which were unsurveyed and were therefore omitted from the surveyadopted by the Department of the Interior. The Métis demanded a distribution of land and scrip, as had occurred in Manitoba after 1870. The Métis action at Batoche encouraged several bands of indigenous nations (Cree, Assiniboine, and Sioux) to take up arms. Threatened with a general rising across theNorthwest Territories, the Canadi...

• Cobra (snake) - biology.

  Most cobras prey on small rodents or other small mammals. They also eat birds, snakes, lizards, frogs, toads, insects, and even eggs. Water cobras catch fish and kingcobras specialize in eating other snakes. Similar to other venomous snakes, cobras use venom to subdue their prey before swallowing it whole, generally head first. Thevenom may contain substances that also break down the prey for digestion. Despite their potent venom and dramatic threat displays, cobras are hunted and eaten by a num...

• Colorado (river, North America) - Geography.

  sometime between AD 1300 and 1400, but their descendants, the Hopi and Pueblo people, continue to farm and irrigate using the river's waters. The first European to visit the river was probably Spanish soldier and explorer Francisco de Ulloa, who explored the mouth of the Colorado in 1539. In 1540 and 1541another Spaniard, Francisco Vásquez de Coronado, traveled through much of the region around the Colorado River. An exploring party from the Coronado expedition,led by Garcia López de Cárdenas,...

  The Kololo, a Sotho people, entered the same region in the early 1820s after being driven from their homeland south of the Vaal River by the Ngwane-Hlubi wars. In1823 the Kololo clashed with the Griqua and turned north into the Kalahari Desert. They eventually crossed the Zambezi and finally settled in what is now westernZambia after overthrowing the powerful Lozi Kingdom in 1840. D Founding of the Sotho Nation The Ngwane-Hlubi wars also drove loosely organized Sotho communities north into the...

• Development (biology) - biology.

  Understanding the molecular machinery within cells gives biologists a direct basis for understanding growth, because growth is the synthesis of new protoplasm, andbiologists know the basic mechanism of this synthesis. One key gap, however, exists in this knowledge. Biologists want to know not only how substances aresynthesized but also how growth is controlled so that the proportions of an animal or plant remain consistent from generation to generation. The direction and amountof growth, which a...

• Photosynthesis - biology.

  P680 in Photosystem II is now electron deficient because it has donated electrons to P700 in Photosystem I. P680 electrons are replenished by the water that has beenabsorbed by the plant roots and transported to the chloroplasts in the leaves. The movement of electrons in Photosystems I and II and the action of an enzyme split thewater into oxygen, hydrogen ions, and electrons. The electrons from water flow to Photosystem II, replacing the electrons lost by P680. Some of the hydrogen ions maybe...

• Camel - biology.

  of water in the stomach or hump as was once commonly believed. Unlike other mammals, however, the camel can survive as long as three weeks without drinking,depending on the water content of its food. It can survive a water loss of about 40 percent of its normal body weight. In comparison, a loss of 15 percent is usually fatalfor humans. Camels can go without water due to several unique adaptations to their environment. The camel conserves more water in its body than any other mammal. It excretes...

• Aging - biology.

  Different theories have been proposed to explain how SF works. One theory is based on the assumption that aging, and diseases that occur more frequently withadvancing age, are caused by structural damage to cells. This damage accumulates in tiny amounts each time the cell divides, eventually preventing the cell fromcarrying out normal functions. One cause of this damage may be free radicals, which are chemical compounds found in the environment and also generated by normal chemical reactions in...

• Hazardous Wastes.

  A Source Reduction The best way to eliminate hazardous wastes is not to generate them in the first place. For example, improvements have been made in the production of integratedcircuits: The toxic chlorinated hydrocarbons commonly used in the 1970s were replaced in the 1980s by less toxic glycol ethers and in the 1990s by low-toxicity estersand alcohols. B Recycling Recycling is the recovery or reuse of usable materials from waste. About 5 percent of hazardous waste in the United States is re...

• Comedy

  Socrates suffered in the comedy of Aristophanes. Throughout history, opposition to comedy and laughter has been strongest in societies which emphasize physical restraint, decorum and conformity. Many medieval monastic orders had statutes forbidding laughter. The Puritan and Victorian eras saw many condemnations of comedy and laughter. The more authoritarian the regime, the greater its suppression of comedy. Hitler even set up ‘joke courts' to punish those who made fun of his regime - one Berl...

• Air Pollution.

  Several pollutants attack the ozone layer. Chief among them is the class of chemicals known as chlorofluorocarbons (CFCs), formerly used as refrigerants (notably in airconditioners), as agents in several manufacturing processes, and as propellants in spray cans. CFC molecules are virtually indestructible until they reach thestratosphere. Here, intense ultraviolet radiation breaks the CFC molecules apart, releasing the chlorine atoms they contain. These chlorine atoms begin reacting withozone, br...
