• Camping.

  Commercial campgrounds serve as campsites for RV and car campers on the outskirts of national and state parks and along highways throughout North America.Owners of commercial campgrounds charge campers on a daily or weekly basis, and provide campsites equipped with hookups for electricity and water. They may alsoprovide such amenities as showers, laundry facilities, or a swimming pool. Many commercial campgrounds belong to a club or network that allows its members toreserve campsites in advance....

• Artificial intelligence

  justice to the normativeness that is integral to the judgment. The issue of the intersubjective validity of a judgmentof artistic value - whether such a judgment can be valid for all people, and, if so, what validates it - has still notbeen adequately resolved. Non-artistic values There are many interesting questions about the relations between artistic value and other kinds of value, especially cognitive value and ethical value. For example: Is there an inherent link between the kindand deg...

• Water Pollution.

  Cryptosporidium in the water supply of Milwaukee, Wisconsin, sickened more than 400,000 people and killed more than 100. H Thermal Pollution Water is often drawn from rivers, lakes, or the ocean for use as a coolant in factories and power plants. The water is usually returned to the source warmer than when itwas taken. Even small temperature changes in a body of water can drive away the fish and other species that were originally present, and attract other species in placeof them. Thermal pol...

• Sydney (Australia) - geography.

  kept pace with demand, mostly through the outward expansion of the metropolitan area. More housing has been created recently in inner areas, including the CBD, onredeveloped industrial sites and in converted commercial buildings. Several outlying areas are part of the greater Sydney conurbation (a large urban area formed by urban sprawl). To the west are areas of commercial strip development extending from Penrith through the Blue Mountains; to the north are the Central Coast area centered on...

• Ocean and Oceanography.

  of sediment. When studied in sedimentary core samples, which can represent many millions of years of deposits, they provide a detailed and continuous history of theearth’s environmental changes. The record is particularly informative for the most recent 2 million to 5 million years, during which major fluctuations in global climatehave occurred. Successive ice ages can be traced by the relative scarcity or abundance of the shells of warm-water and cold-water diatoms in various layers of asedimen...

• 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...

• 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...

• Monkeys.

  Female monkeys usually give birth to only one baby at a time. The baby stays with its mother while itfeeds on her milk. In many species, the females stay with their mother’s family group for life. Malesoften leave their mother’s family group when they grow up. Compared to other animals, monkeys live a long time. It’s hard to know how long a monkey in the wildwill live. But some monkeys in zoos have lived to be more than 50 years old. WHAT DO MONKEYS EAT? What a monkey eats depends on the size of...

• Central America - Geography.

  F Animal Life Most of the animal life of Central America is similar to that of South America, but some animals have ties with North America. The marley and opossum have links withSouth America, as do the jaguar, ocelot, jaguarundi, and margay, which are members of the cat family. In contrast, the puma, gray fox, and coyote are of NorthAmerican origin. The armadillo, anteater, and sloth have ties to the south, deer to the north. The large manatee, an aquatic plant eater, survives in the isolated...

• Metabolism (chemistry) - biology.

  nearly perfect balance. Although much remains to be revealed about metabolic processes, biochemists now agree that regulatory, or rate-limiting, enzymes figure largely in the reactionsinvolved ( see Enzyme). Affecting metabolic pathways at the earliest steps, each enzyme molecule has a specific, or active, site that matches, or “fits,” its particular substrate—the compound with which the enzyme forms a product. The precision with which rate-limiting enzymes and substrates join to set off a parti...

• Encyclopedia of Philosophy: Adverbs

  arguments to a predicate actually function as adverbial modifiers. Perhaps the best known account of this type isRoderick Chisholm's discussion of a certain class of statements about appearances. Chisholm suggests that a manwho ‘sees spots before his eyes' should be thought of as ‘sensing in a spotty manner' or as someone whom things‘appeared to spottily' ( 1957 ). This philosophical move is designed to rid the locution of any implication that in sensing spots before his eyes the man is...

• Electric Motors and Generators.

  the armature. It is often desirable to generate as high a voltage as possible, and rotating armatures are not practical in such applications because of the possibility of sparkingbetween brushes and slip rings and the danger of mechanical failures that might cause short circuits. Alternators are therefore constructed with a stationary armaturewithin which revolves a rotor composed of a number of field magnets. The principle of operation is exactly the same as that of the AC generator described,...

• Andes - geography.

  smaller trees lies above the zone of rain forest. Among the smaller trees is found the wild cinchona, a source of quinine, a drug used to treat malaria. In the southernAndes, broadleaf and coniferous trees cover the lower slopes. Coniferous forests are found above 2,000 m (6,500 ft), and the timberline is generally about 3,000 m(about 10,000 ft) above sea level. Above the timberline are treeless highland meadows, but the high plateaus of the central Andes support only a sparse covering ofgrasses...

• Burundi - country.

  D Way of Life Most Burundians live in self-contained compounds of small round grass huts scattered over the country’s many hills. The rugo , the traditional Tutsi hut, is divided into sections and surrounded by an enclosure and cattle corrals. Families farm scattered plots of land on different soils at different altitudes to minimize crop failure. Thefloors of valleys are avoided due to higher temperatures and tsetse fly infestation. Social roles are largely determined by ethnicity, with the T...

• Rhinoceros - biology.

  Male and female rhinos have a similar physical appearance, although male rhinos are usually larger than females, with the size difference varying between species. Inthe wild, some rhinos probably live into their late 40s, and they have survived into their 30s in captivity. IV TYPES OF RHINOCEROSES Until recently, mammalogists divided the rhinoceros family into three subfamilies, each with different characteristics. Scientists now believe that living rhinos belong to asingle subfamily, although...

• Tom Jones (1749) Henry Fielding Book I -- Chapter 1 An author ought to consider himself, not as a gentleman who gives a private or eleemosynary treat, but rather as one who keeps a public ordinary, at which all persons are welcome for their money.

  True wit is nature to advantage drest; What oft was thought, but ne'er so well exprest. The same animal which hath the honour to have some part of his flesh eaten at the table of a duke, may perhaps be degraded in another part, and some of his limbs gibbeted, as it were, in the vilest stall in town. Where, then, lies the difference between the food of the nobleman and the porter, if both are at dinner on the same ox or calf, but in the seasoning, the dressing, the garnishing, and the setting for...

• Koala - biology.

  V REPRODUCTION Female koalas become sexually mature around 18 to 24 months of age. They can produce one offspring a year until they reach about 13 years of age. Males begin toproduce sperm around age 2 and, in the absence of older, stronger males, they may breed at that young age. More often, however, a male must grow big enough tocompete with other males for females, and mating generally begins for males at about 4 years of age. The breeding season for koalas is from October to May, during the...

• Reproductive System.

  in which the young develop, and a thinner channel, the vagina, which opens exteriorly. V GENITALS In animals that lay their eggs and discharge their sperm into water, the spermatozoa reach the eggs by chemical attraction; the eggs of individuals of a species attractonly the sperm of members of the same species. When eggs and sperm are deposited at great distances from each other, the number of eggs fertilized is small. Manyamphibians and aquatic vertebrates solve this problem by attaching thems...

• Antelope - biology.

  antelopes still display complex patterns of behavior, although much of it is instinctive rather than learned. In open habitats, antelopes run a high risk of predation (being preyed upon). To survive they use several kinds of defensive strategy, including living in herds. Herd living ensures that many pairs of eyes and ears are on the alert for danger. Herd living also gives individuals a better chance of avoiding attack, because predators canchoose from many potential targets. When danger thre...

• Valley.

  Except in mountainous terrain, rivers are almost always flanked by floodplains. Floodplains are flat wide deposits of alluvium, river-deposited sediment, on either side of the river channel. During floods, a river overflows its banks and spreads out the sediment near the river to form a floodplain. Floodplains of large rivers, such as thoseof the Mississippi River, can be flat areas tens of kilometers across. River channels migrate back and forth across their floodplains as alluvium is repeate...

• Bird - biology.

  B Physical Adaptations for Flight The internal body parts of all birds, including flightless ones, reflect the evolution of birds as flying creatures. Birds have lightweight skeletons in which many of themajor bones are hollow. A unique feature of birds is the furculum, or wishbone, which is comparable to the collarbones of humans, although in birds the left and rightportions are fused together. The furculum absorbs the shock of wing motion and acts as a spring to help birds breathe while they...

• Comparative Anatomy.

  In comparing two species, anatomists have to be careful to differentiate between homologous structures, which are ones that have evolved from a shared ancestor, andanalogous structures, which have developed from different origins. Homologous structures are built on the same underlying plan. A human arm, a bat’s wing, and awhale’s flipper look quite different from the outside, but the bones inside reveal that these limbs all have the same basic structure. Analogous structures, by contrast,often l...
