• African American History - U.

  In their day-to-day lives, slaves and servants shared similar grievances and frequently formed alliances. Advertisements seeking the return of slaves and servants whohad run away together filled colonial newspapers. When a slave named Charles escaped in 1740, the Pennsylvania Gazette reported that two white servants, a 'Scotch man' and an Englishman, escaped with him. Sometimes interracial alliances involved violence. During Bacon's Rebellion in 1676, slaves and servants took up armsagainst Na...

• Executive Branch.

  Popular pressure for increased regulation of businesses increased in the early 20th century. This pressure led to laws such as the Pure Food and Drug Acts, and the1906 Meat Inspection Act. Pressure for reform also led to creation of the Federal Trade Commission in 1914 to prevent unfair business practices. Worldwide depressionin the 1930s brought new demands that government take a more activist role in regulating businesses, protecting workers, and ensuring national economic stability. Aspart of...

• Puppets I INTRODUCTION Punch and Judy Punch and Judy are characters in an English hand puppet show that first appeared in 1662.

  Rod puppets are controlled by rods attached to their limbs, heads, and bodies. Although the traditional rod puppets of Belgium and Sicily are worked from above, likemarionettes, most contemporary rod figures are operated from below. In theaters, rod puppeteers are frequently concealed from view by drapery or stage flats (fabric stretched across frames). On television and in films, rod and hand puppeteers usually hold their figures either above their heads or in front of their faces. In the lat...

• Moon - astronomy.

  B Volcanic Features Maria, domes, rilles, and a few craters display indisputable characteristics of volcanic origin. Maria are plains of dark-colored rock that cover approximately 40 percent ofthe Moon's visible hemisphere. The maria formed when molten rock erupted onto the surface and solidified between 3.16 billion and 3.96 billion years ago. This rockresembles terrestrial basalt, a volcanic rock type widely distributed on Earth, but the rock that formed the maria has a higher iron content an...

• 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...

• Bicycle.

  narrow as possible to minimize weight and interference with pedaling. F Specialty Bicycles Many other types of bicycles are designed for special purposes. Although not as common as standard single-rider racing, touring, mountain, or recreational bicycles,they nonetheless have significant niches. Recumbent bicycles are bicycles on which the rider sits upright as if in a chair, with legs and feet stretched out in front. Because they support the rider’s lower back,recumbents allow the rider far mo...

• 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...

• Elementary Particles I INTRODUCTION Structure of Matter Modern physics has revealed successively deeper layers of structure in ordinary matter.

  The most fundamental particles that make up matter fall into the fermion category. These fermions cannot be split into anything smaller. The particles that carry theforces acting on matter and antimatter are bosons called force carriers. Force carriers are also fundamental particles, so they cannot be split into anything smaller.These bosons carry the four basic forces in the universe: the electromagnetic, the gravitational, the strong (force that holds the nuclei of atoms together), and the wea...

• Hungary - country.

  Northern Hungary lacks sufficient water, especially between July and October, when precipitation levels are typically low. Canals irrigate the Great Hungarian Plain,which is subject to drought. Because of the country’s mainly flat terrain, only limited water resources can be harnessed for hydroelectric power. F Environmental Issues Rapid industrialization in Hungary following World War II contributed significantly to a number of major environmental problems, including air, water, and soil pollu...

• The Saponification

  // III.)The energy needed With the surface tension decreased, the soapy water needs some energy to form bubbles. This energy comes from us blowing, waving, or even when the tap is flowing. This puts air into the bubble and the bubble is created. The bubble is mostly spherical because it is the shape that consumes the less energy. Plus it needs less air than a cube or a pyramid. Bubbles are generally small because it takes less energy and less molec...

• Helium - chemistry.

  the bends. This synthetic atmosphere is also used in medicine to relieve sufferers of respiratory difficulties because helium moves more easily than nitrogen throughconstricted respiratory passages. In surgery, beams of ionized helium from synchrocyclotron sources are proving useful in treating eye tumors, by stabilizing or evenshrinking the tumors. Such beams are also used to shrink blood-vessel malformations in the brains of patients. Helium is used in inert-gas arc welding for light metals, s...

Among his secular illustrations were those for an edition of Thomas Gray’s poems and the 537 watercolors for Ed...

• Republic (government).

  South African Republic (1852) and the Orange Free State (1854), were finally annexed by Britain after the Boer War (1899-1902). Both in the United States and otherrepublics, however, the passage of the century was generally marked by democratization of the electoral process through the enlargement of the electorate. Two waves of new-state formations occurred in the 20th century—the first one after World War I, the second after World War II. Most of the newly independent statesestablished themsel...

• Programming Language.

  Logic languages use logic as their mathematical base. A logic program consists of sets of facts and if-then rules, which specify how one set of facts may be deducedfrom others, for example: If the statement X is true, then the statement Y is false. In the execution of such a program, an input statement can be logically deduced from other statements in the program. Many artificial intelligence programs are writtenin such languages. IV LANGUAGE STRUCTURE AND COMPONENTS Programming languages use...

• Arab Music I INTRODUCTION Umm Kulthum Egyptian singer Umm Kulthum was revered throughout Egypt, North Africa, and the Near East for her powerful voice and improvisational skill.

  The rhythmic structure of Arab music is similarly complex. Rhythmic patterns have up to 48 beats and typically include several downbeats (called dums ) as well as upbeats (called taks) and silences, or rests. To grasp a rhythmic mode, the listener must hear a relatively long pattern. Moreover, the performers do not simply play the pattern; they elaborate upon and ornament it. Often the pattern is recognizable by the arrangement of downbeats. The Rhythm in Arab Music illustration demonstratesa...

• Business.

  The most common form of ownership is a sole proprietorship —that is, a business owned by one individual. At the beginning of the 21st century, there were more than 17 million sole proprietorships in the United States. These businesses have the advantage of being easy to set up and to dissolve because few laws exist to regulatethem. Proprietors, as owners, also maintain direct control of their businesses and own all their profits. On the other hand, owners of proprietorships are personallyrespon...
