McGraw Hill Financial, Inc. is an American publicly traded corporation headquartered in Rockefeller Center in New York City. Its primary areas of business are financial, publishing, and business services.
A self-pollinated, one- to six-seeded legume. It is cultivated throughout the tropical and temperate climates of the world. The oil, expressed from the seed, is of high quality, and a large percentage of the annual world production is used for this purpose. In the United States some 65% goes into the cleaned and shelled trade, the end products of which are roasted or salted peanuts, peanut butter, and confections.

A semiaquatic, carnivorous mammal in the family Mustelidae. The American mink (<i>Mustela vison</i>) is found in Alaska and Canada and throughout most of the United States. The range extends southward in the western United States to northern New Mexico, northern Nevada, and central California. This species was deliberately introduced into the former Soviet Union, and escaped animals have established populations in France, Spain, Portugal, Germany, Poland, Ireland, Great Britain, and Scandinavia, as well as in Iceland.
Industry:Science
A semiconductor device with electrical characteristics that are light-sensitive. Phototransistors differ from photodiodes in that the primary photoelectric current is multiplied internally in the device, thus increasing the sensitivity to light. For a discussion of this property
Industry:Science
A semiconductor electrical junction device which directly and efficiently absorbs the radiant energy of sunlight and converts it into electrical energy. Solar cells may be used individually as light detectors, for example in cameras, or connected in series and parallel to obtain the required values of current and voltage for electric power generation.
Industry:Science
A semiconductor two-terminal component with electrical characteristics that are light-sensitive. All semiconductor diodes are light-sensitive to some degree, unless enclosed in opaque packages, but only those designed specifically to enhance the light sensitivity are called photodiodes.
Industry:Science
A semienclosed basin adjacent to the North Pacific Ocean, bounded on the north, east, and west by continental Russia, the Kamchatka Peninsula, and northern Japan (see <b>illus.</b>). On its southeast side the Sea of Okhotsk is connected to the North Pacific via a number of straits and passages through the Kuril Islands. The sea covers a surface area of approximately 590,000 mi<sup>2</sup> (1.5 million km<sup>2</sup>), or about 1% of the total area of the Pacific, and has a maximum depth of over 9000 ft (3000 m). Its mean depth is about 2500 ft (830 m). Owing to the cold, wintertime Arctic winds that blow to the southeast, from Russia toward the North Pacific Ocean, the Sea of Okhotsk is partially covered with ice during the winter months, from November through April.
Industry:Science
A semienclosed brackish sea located in a humic zone, with a positive water balance relative to the adjacent ocean (the North Sea and the North Atlantic). The Baltic is connected to the North Sea by the Great Belt (70% of the water exchange), the Øresund (20% of the water exchange), and the Little Belt. The total area of the Baltic is 147,414 mi<sup>2</sup> (381,705 km<sup>2</sup>), its total volume 4982 mi<sup>3</sup> (20,764 km<sup>3</sup>), and its average depth 181 ft (55.2 m). The greatest depth is 1510 ft (459 m), in the Landsort Deep.
Industry:Science
A semi-viny annual legume with slender tufted and branched stems 18–22 in. (46–56 cm) long. The lentil plant (<i>Lens esculenta</i>) was one of the first plants brought under cultivation. They have been found in the Bronze Age ruins of the ancient lake dwellings of St. Peter's Island, Lake of Bienne, Switzerland. Lentils have been discovered in Poland dating back to the Iron Age. In the Bible the “red pottage” for which Esau gave up his birthright to his brother, Jacob, was probably lentil soup. Large-seeded lentils originated in the Mediterranean region; medium-sized lentils originated in the inner mountains of Asia Minor; and Afghanistan was the original home of the smallest-seeded lentils.
Industry:Science
A sensitive reaction used in serology for the detection of either antigen or antibody, as in the diagnosis of many bacterial, viral, and other diseases, including syphilis. It involves two stages: stage I is the binding or fixation of complement if certain antigen-antibody reactions occur, and stage II is detection of residual unbound complement, if any, by its hemolytic action on the sensitized erythrocytes subsequently added. This is shown in the <b>illustration</b>.
Industry:Science
A sensor that is based on a thick-film circuit. Thick-film circuits are formed by the deposition of layers of special pastes onto an insulating substrate. The pastes are usually referred to as inks, although there is little resemblance to conventional ink. The printed pattern is fired in a manner akin to the production of pottery, to produce electrical pathways of a controlled resistance. Parts of a thick-film circuit can be made sensitive to strain or temperature. The thick-film pattern can include mounting positions for the insertion of conventional silicon devices, in which case the assembly is known as a thick-film hybrid. The process is relatively cheap, especially if large numbers of devices are produced, and the use of hybrid construction allows the sensor housing to include sophisticated signal conditioning circuits. These factors indicate that thick-film technology is likely to play an increasing role in sensor design.
