The central plains region, also known as the Channel Country, is interlaced by a network of rivers.

Through Jung’s Psych\bl\bgy and Alchemy—an exposition of “the problem of individuation” and “normal development . . . in a highly intelligent person”—depth psychologists have known the Nobel laureate’s dreams, not his professional genius.

Public two-way radios with severalfrequency options are widely available as well. Usually limited in range to a few miles, these units are great aids for such mobile professionals as construction workers,film crews, event planners, and security personnel. Simpler two-way radios, called walkie-talkies, have been popular children’s toys for years. Most walkie-talkiesb...

  compensator (or control) device (BCD or BC), which the diver wears as a vest. By adding air to the BCD, the diver becomes more buoyant and rises. By releasing air,the diver becomes less buoyant and sinks. With minor adjustments of air, the diver can achieve neutral buoyancy. A third hose attaches to pressure gauges that diversuse to monitor how much air remains in the tank. A fourth hose attaches to a backup breathing device called an alternate air source, or octopus. Divers also wear a belt w...

Archaeologists have found primitive, handmade toys such as wooden or cloth dolls, clay marbles, and terracotta figures that date back thousands of years. In ancientEgypt, Greece, and Rome, people placed dolls or clay figures in the graves or tombs of children for them to play with in the afterlife.

• Japanese Literature I INTRODUCTION Japanese Literature, literature of Japan, in written form from at least the 8th century AD to the present.

  The Man’yō’sh ū contains about 4,500 poems, most of them composed in the Nara period (710-784). Some of the poems are far older, however, and some of the verses date to earlier collections that have not survived. The work demonstrates a gradual change from basic verses on simple subjects to more sophisticated expressions with a broad range of subject matter. This text also shows the development of poetic forms such as the tanka (short poem), a form structured around alternating lines of 5 an...

• Astronomy - astronomy.

  Telescopes may use either lenses or mirrors to gather visible light, permitting direct observation or photographic recording of distant objects. Those that use lenses arecalled refracting telescopes, since they use the property of refraction, or bending, of light ( see Optics: Reflection and Refraction ). The largest refracting telescope is the 40-in (1-m) telescope at the Yerkes Observatory in Williams Bay, Wisconsin, founded in the late 19th century. Lenses bend different colors of light by d...

  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...

  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.

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...
