• Cheetah - biology.

  animals such as zebras. Unlike most cats, cheetahs hunt during the day, when lions and hyenas that compete with them for prey are less likely to be active. Still,scientists in Tanzania have observed that cheetahs lose 10 to 13 percent of their kills to lions and hyenas. Alerted by the panic of a gazelle herd or by the circling ofvultures, lions and hyenas close in and easily drive the more timid cheetah away from a fresh kill. A cheetah usually stalks prey to within about 10 m (about 33 ft) and...

• Arithmetic I INTRODUCTION Arithmetic, branch of mathematics that arises from counting, the most basic mathematical operation.

  Subtract the units: 6 - 3 = 3. Then subtract the tens column: 6 – 2 = 4. The results of these two single-digit subtractions, written side by side, provide the answer: Subtraction is a bit more complicated if we need to subtract a larger digit from a smaller one. For example, when subtracting 47 from 92, the units value (7) of 47 isgreater than the units value (2) of 92. We can handle this situation using a procedure called borrowing, which is like carrying in reverse. Ten units can be borrowe...

• American Literature: Drama I INTRODUCTION American Literature: Drama, literature intended for performance, written by Americans in the English language.

  American plays, while still a minority, began to appear in the theater repertory in the 19th century.

In the United States as in Britain, many plays reflected the influence of romanticism , a European literary and artistic movement. Melodrama, with its outpourings of emotion, was the most prevalent dramatic form in the 19th century. Gothic melodramas...

• Psychotherapy.

  Other managed-care companies pay therapists a set fee to meet with a client for up to a specified maximum number of sessions depending on the nature of theproblem, free of interference from case reviewers. For example, a managed-care firm may pay a therapist $200 to hold up to eight sessions with a person. If the clientuses all eight sessions, the therapist normally loses money. But if treatment stops after two or three sessions, the therapist makes a profit. This relatively new system iscontrov...

  2 U-curve of adjustment. The idea is quite simple: if the level of adjustment, adaptation and well-being over time is drawn, a U- shape appears. Upon tasting the new culture he is in good spirits, but gradually encounters more and more problems eventually leading to the lowest point of despair and disappointment. In the middle of the crisis (cultur e shock), there seems to be no way out. The student has hit the botto...

• W. L. Mackenzie King. I INTRODUCTION W. L. Mackenzie King (1874-1950), tenth prime

  V SECOND TERM AS PRIME MINISTER By the election of 1925 most of the rifts in the Liberal Party were healed. Little had been achieved by King's government except for some tariff reduction and thereorganization of Canadian railroads, but no mistakes had been made. The real issue of the election was the personalities of the party leaders, King and the brilliant butarrogant Conservative, Arthur Meighen. The Conservatives swept English-speaking Canada, and they won 116 seats. The Liberals won 101, a...

• Spanish-American War.

  A Blockade of Cuba The Navy’s basic job was to blockade the island of Cuba. If the Spanish army could be cut off from seaborne supplies from Spain, it could not maintain itself for longagainst the Cuban insurgents, let alone prepare to fight the U.S. forces. To maintain a successful blockade, the U.S. Navy would have to control the sea approaches toCuba. To accomplish this, the United States determined that the Spanish navy had to be destroyed wherever it was found. Thus the U.S. war objectives...

• Asteroid - astronomy.

  Asteroids of the S type, related to the stony iron meteorites, make up about 15 percent of the total population of asteroids that can be seen from Earth. Much rarer arethe M-type objects, corresponding in composition to the meteorites known as “irons.” These objects are made up of an iron-nickel alloy and may represent the cores ofbodies that were large enough to differentiate into layers and to melt deep inside. Their rocky outer layers may have been removed by impacts with other asteroids . A...

• Electoral College.

  III HISTORY OF THE ELECTORAL COLLEGE A Origins One thing is clear about the political theory underpinning the electoral college: The framers of the Constitution could not agree on one. From the outset, the framerswere uncertain about how the president should be chosen. Meeting in the Constitutional Convention in Philadelphia, Pennsylvania, in 1787, the framers originally decidedto have Congress choose the president, and that there should be no popular vote to elect the president. Then the Con...

• Physics I INTRODUCTION Physics, major science, dealing with the fundamental constituents of the universe, the forces they exert on one another, and the results produced by these forces.

  Starting about 1665, at the age of 23, Newton enunciated the principles of mechanics, formulated the law of universal gravitation, separated white light into colors,proposed a theory for the propagation of light, and invented differential and integral calculus. Newton's contributions covered an enormous range of naturalphenomena: He was thus able to show that not only Kepler's laws of planetary motion but also Galileo's discoveries of falling bodies follow a combination of his ownsecond law of m...

Codified/uncodified are better description than written/unwritten to better distinguish the UK constitution from that of other countries because most of the UK constitution is written but has never been codified into one single document. Yet flexibility should not be unrestrained, that is to say an ability to evolve can be constrained by existi...

• Penguin - biology.

  B Parents and Offspring Once female penguins lay their eggs, both the parents incubate the eggs. The incubation period varies according to species, ranging from 33 days for the little penguinto about 63 days for the emperor penguin. In most medium-sized penguins incubation takes 35 to 38 days. The incubation routine is highly variable among penguinspecies, although in general both sexes participate in incubation and feeding of young. Male and female Adélie penguins take turns incubating their e...

  pectoral fins provide fine movements, add forward thrust, or, together with the pelvic fins, serve as brakes. Typically, fins consist of a thin membrane stretched over afanlike series of thin rods called spines or rays. Most fish breathe underwater with the help of special respiratory organs called gills. Gills are made of a series of thin sheets or filaments through which blood circulates.As water moves into a fish’s mouth and passes over the gills, dissolved oxygen passes across the thin gill...

Less powerful punches often serve the important role of settingup the fighter’s chief “weapons,” as boxing analysts sometimes call a boxer’s main offensive skills.

A smart boxer will first test the opponent by trying different feints, noting the reaction to each onebefore deciding which will b...

• Extrasolar Planets - astronomy.

  When a planet passes in a front of the star it orbits—an event called a transit—it causes a small dip in the brightness of the star. Measuring the slight change in thebrightness can be used not only to directly detect a planet, but to determine its size and orbit. However, the planet needs to orbit in a plane that lies in a telescope’sline of sight on the star. Despite long odds, Earth-based telescopes have detected and studied a few exoplanets using this method. The first space telescope design...

  There are two standard methods of recording chess moves: the algebraic system and the descriptive system. In both systems, the pieces are designated by capitalinitials: K for king, Q for queen, R for rook, B for bishop, and N for knight. The initial P for pawn is used in the descriptive system only. Castling is noted as either 0-0(“short” castling on the king’s side) or 0-0-0 (“long” castling on the queen’s side). Each square is part of both a file and a rank, and in the algebraic system, that u...
