• Venus (planet) - astronomy.

  level winds circle the planet at 360 km/h (225 mph), making a complete rotation in only four days. These winds are said to super-rotate because they travel muchfaster than the rotation of the planet itself. These high-speed winds cover the planet completely, blowing toward the west at virtually every latitude from equator topole. The motions of descending probes, however, have shown that the bulk of Venus’s tremendously dense atmosphere, closer to the planet’s surface, is almoststagnant. From th...

  D Coat Colors The domestic cat's original coat color was probably grayish-brown with darker tabby stripes, a color that provides excellent camouflage in a variety of environments. Allother coat colors and patterns are the result of genetic mutations; for example, solid coat colors such as black and blue are the result of a gene that suppresses tabbystripes; an orange coat is the result of a gene that transforms black pigment to orange; and a solid white coat is the result of a gene that complet...

• Stem Cell.

  The medical profession used adult stem cells to treat diseases long before anyone isolated one. In 1968 scientists performed the first successful bone marrowtransplant, a procedure in which a patient receives an infusion of healthy bone marrow cells. The purpose of such transplants is to restore the blood-making capabilitiesof the patient’s diseased bone marrow after extremely strong chemotherapy has destroyed that bone marrow. From the beginning investigators suspected that stemcells in the inf...

  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...

A varying number of line judges sit around the courtbeyond the path of the players. Line judges determine whether serves and shots are good or out. A net-cord judge may be employed to determine when a ball touchesthe top of the net, and a foot-fault judge may watch for that specific infraction. In the 1980s electronic devices began to be used in some professional tournaments...

• 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...

• Acting I INTRODUCTION Lee Strasberg American acting teacher Lee Strasberg was best known for his association with the Actors Studio, of which he became the artistic director in 1951.

  truthfully felt those emotions at the moment they expressed them. Finding the true feeling in the proper place and time on stage, however, was a problem that Aristotleaddressed less well. He concluded that acting was an occupation for the gifted or insane. How to cross the artistic boundary beyond feigned emotions and flat imitation obsessed many Greek actors. In 315 BC the tragedian Polus carried the real ashes of his recently deceased son in an urn to stimulate a sense of genuine grief when h...

  formulas of some logical language, and that the reasoning tasks underlying this intelligence can then be accomplished by means of logical deduction. Both the idea of using logic as an underlying representation language for artificial intelligence and the emphasis on formalizing common-sense knowledge are present even in McCarthy's very early work (for example, McCarthy 1959 ), but the project receives its clearest articulation in a paper jointly authored by McCarthy and Patrick Hayes (1969 )...

• Wolfgang Amadeus Mozart.

  including the sacred style of church music and the so-called galant (courtly) idiom. The elegant though often superficial galant style dominated much instrumental music of the 1760s and 1770s. Mozart’s mastery often demonstrates itself in an ability to expand and deepen the stylistic possibilities of the time. The manner in which heextended the character and form of the concerto, for instance, owes much to his experience in writing operatic arias. A Musical Expressiveness In the masterful Je...

Because Roosevelt himself was satisfied that Taft's election would ensure that his reform programs were continued, he used hisinfluence with each state's Republican Party to get Taft the nomination.

Some peoplehave genetic traits that help them resist malaria. Sickle-cell anemia and thalassemia, for example, are inherited blood disorders linked to malaria resistance. Travelers who lack immunity to malaria should take precautionary measures when visiting areas where the disease is prevalent. Such measures include using insectrepellents,...

L’œuvre d’Arvid Järnefelt (1861-1932) est placée quant à elle sous la figure tutélaire de Léon Tolstoï, avec lequel il partage la haine du matérialisme, une certaine exaltation de la nature, et une critique sociale ( les Fils de la terre — Maaemon Lapsia, 1905). Le naturalisme littéraire est représenté par les œuvres des romanciers Joel Lehtonen (1881-1934) et Toivo Pekkanen (1902-1957). Le premier se détache progressivement du roma...

  Ses travaux ont porté sur la pesanteur, le vide et la pression, l'hydrostatique ( voir Fluides, mécanique des), la géométrie, l'arithmétique, les probabilités et les mathématiques. Dès son Essay pour les coniques (1640), Pascal utilisa la méthode projective pour déduire les propriétés des coniques du théorème sur l'hexagramme. À la suite de Torricelli, disciple de Galilée, il se livra à l'étude de la question du vide : « la nature a horreur du vide » pensait-on depuis le Moyen Âge. En 16...

• X-Ray Astronomy - astronomy.

  Some neutron stars have weaker magnetic fields that allow incoming material to settle onto the entire surface of the neutron star. Eventually, so much material buildsup that the surface layer becomes dense enough to set off a vast thermonuclear explosion, called an outburst. The explosion heats gas to produce X rays. Such aneutron star—called an X-ray burster—can increase its X-ray production by a million times during an outburst. The X-ray glow fades over time, and the binary systementers a lon...

• Election.

  majority systems usually reduce the number of competitive political parties—for example, the mostly two-party system in the United States. Proportional representation systems boost participation by increasing the value of a vote to smaller or more marginal portions of a national population. In the UnitedStates, plurality or majority systems have reduced the incentive to vote of citizens who do not identify closely with the Democratic or Republican Party. Disillusionmentwith the major parties and...

• Suicide.

  C Sociological Theories Most social scientists believe that a society’s structure and values can influence suicide rates. French sociologist Émile Durkheim argued that suicide rates are related tosocial integration —that is, the degree to which an individual feels part of a larger group. Durkheim found suicide was more likely when a person lacked social bonds or had relationships disrupted through a sudden change in status, such as unemployment. As one example of the significance of social bond...

  III SURGICAL PROCEDURES Surgical procedures are classified as optional, required, elective, urgent, and emergent based on the patient’s medical condition. Optional surgery consists of operationsthat are not required but which the patient chooses to undergo as with some types of cosmetic surgery.

• Sleep - biology.

  V FUNCTIONS OF SLEEP Although no one knows for sure why we sleep, there are a number of theories. Sleep may have evolved to protect animals from their predators by reducing theiractivity during the times when they are most vulnerable. Research has shown that REM and NREM sleep may serve specific biological functions. Sleep deprivation studies reveal that humans and other animals respond to sleeploss in the same way. When study subjects are deprived of REM sleep, they tend to spend longer period...
