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 cool-season biennial crucifer (<i>Brassica oleracea</i> var. <i>gemmifera</i>), which is of northern European origin and belongs to the plant order Capparales. The plant is grown for its small headlike buds formed in the axils of the leaves along the plant stem (see <b>illus.</b>). These buds are eaten as a cooked vegetable. Cultural practices are similar to those used for cabbage; however, monthly mean temperatures below 70°F (21°C) are necessary for firm sprouts. Brussels sprouts are moderately tolerant of acid soils and have a high requirement for boron. Popular varieties (cultivars) are Half Dwarf and Catskill; however, hybrid varieties are increasingly planted. Harvesting begins when the lower sprouts are firm and 1–2 in. (2.5–5 cm) in diameter, usually 3 months after planting. California and New York are important producing states.

A cool-season biennial crucifer, <i>Brassica caulorapa</i> and <i>B. oleracea</i> var. <i>caulo-rapa</i>, of northern European origin belonging to the plant order Capparales. Kohlrabi is grown for its turniplike enlarged stem, which is usually eaten as a cooked vegetable (see <b>illus.</b>). Kohlrabi is a German word meaning cabbage-turnip and reflects a similarity in taste and appearance to both vegetables. Cultural practices for kohlrabi are similar to those used for turnips. White Vienna and Purple Vienna are popular varieties (cultivars). Harvesting, when the enlarged stems are 2–3 in. (5–8 cm) in diameter, is usually 2 months after planting. A common cooked vegetable in Europe, especially Germany, kohlrabi is of minor importance in the United States.

A cool-season biennial crucifer, <i>Brassica oleracea</i> var. <i>acephala</i>, similar to nonheading cabbage. Collard is of Mediterranean origin and is grown for its rosette of leaves which are cooked fresh as a vegetable (see <b>illus.</b>). Kale and collard differ only in the form of their leaves; both have been referred to as coleworts, a name taken from the Anglo-Saxon term meaning cabbage plants.

A cool-season biennial crucifer, <i>Brassica oleracea</i> var. <i>italica</i>, of Mediterranean origin, belonging to the plant order Papaverales. Broccoli is grown for its thick branching flower stalks which terminate in clusters of loose green flower buds (see <b>illus.</b>). Stalks and buds are cooked as a vegetable or may be processed in either canned or frozen form. Cultural practices for broccoli are similar to those used for cabbage.

A cool-season legume with an upright stem, leaves divided into several digitate leaflets, and terminal racemes of pea-shaped blossoms. Three species, yellow, blue, and white, each named for the color of its blossoms, are cultivated as field crops; several hybrids are grown as ornamentals; and many species occur as wild plants. The yellow crop varieties are usually the earliest and smallest, the whites latest and largest. Field crop lupines have been grown in Europe since early Roman times as a soil-improving crop. The older varieties could not be used as forage since the plants contained a bitter, water-soluble, toxic alkaloid. However, since 1912, plant breeders have developed “sweet” varieties with only traces of alkaloid.
Industry:Science
A coordinated group of instruments that provides the flight crew with information about the aircraft and its subsystems. Together with the controls, aircraft instruments form the human–machine interfaces that enable the flight crew to operate the aircraft in accordance with the flight plan. These instruments provide flight data, navigation, power plant performance, and aircraft auxiliary equipment operating information to the flight crew, air-traffic controllers, and maintenance personnel. While not considered as instrumentation, communication equipment is, however, directly concerned with the instrumentation and overall indirect control of the aircraft.
Industry:Science
A coordinating and integrating system which functions in the adaptation of an organism to its environment. An environmental stimulus causes a response in an organism when specialized structures, receptors, are excited. Excitations are conducted by nerves to effectors which act to adapt the organism to the changed conditions of the environment. In animals, humoral correlation is controlled by the activities of the endocrine system. This article considers the morphology, histology, and embryology of the nervous system, including the brain and cranial nerves, and embryology of the sense organs.

A copepod order of crustaceans containing 122 species in five genera, <i>Cymbasoma</i>, <i>Guanabaraenia</i>, <i>Monstrilla</i>, <i>Monstrillopsis</i>, and <i>Thaumatohessia</i>; Monstrillidae is the only family. Previously, the five species of the family Thaumatopsyllidae had been included as a second family of Monstrilloida, but in 2003 this family was removed to its own order, Thaumatopsylloida, and unpublished observations of the development support this decision.
Industry:Science
A copepod order of crustaceans containing four species. <i>Mormonilla minor</i> and <i>M. phasma</i> were described by Wilhelm Giesbrecht in the late 1800s; <i>M. polaris</i> and <i>M. atlantica</i> were described by Georg Ossian Sars and Richard Norris Wolfenden, respectively, in the early 1900s. The status of a fifth species in a second genus, Thomas Scott's <i>Corynuropis tenuicaudatus</i>, remains uncertain. In 1992, males of the order were collected and described for the first time.
Industry:Science
A copepod order of free-living crustaceans made up of 34 species in 16 genera and 3 families. <i>Misophria pallida</i> was the first species described, by Axel Boeck in 1865, from a sample taken close to the sea floor in shallow water. A second genus and species, <i>Benthomisophria palliata</i>, was established by Georg Ossian Sars in 1909 for a bathypelagic species from the North Atlantic Ocean. The remaining species have been described since 1964 and reflect an increased interest by taxonomists in this order of copepods. Many of the recently described species have been recovered during the exploration of anchialine caves, which are coastal marine water bodies with subsurface rather than surface hydrologic connections to the sea. Anchialine caves are one category of crevicular habitat in coastal marine geological formations. The number of known species of Misophrioida is expected to increase significantly, as similar habitats, such as the interstices of coral reefs, are explored more systematically.
