The operational techniques and the activities that sustain the quality of a product or service in order to satisfy given requirements. Quality control is a major component of total quality management and is applicable to all phases of the product life cycle: design, development, manufacturing, delivery and installation, and operation and maintenance.
Industry:Science
The study of the etiologies, mechanisms, and manifestations of disease. Techniques and knowledge gained from other disciplines, including anatomy, physiology, microbiology, biochemistry, and histology, are utilized. The information obtained from the study of pathology is necessary prior to developing methods with which to control and prevent disease.
Industry:Science
The study of the glands of internal secretion, the endocrine glands, and the hormones which they synthesize and secrete. These glands are ductless; the hormones are secreted directly into the blood to be carried to the target tissue or organ. The hormones, or chemical messengers, are highly specific and their action may be selective or generalized.
Industry:Science
The thin film of living organisms and their environments at the surface of the Earth. Included in the biosphere are all environments capable of sustaining life above, on, and beneath the Earth's surface as well as in the oceans. Consequently, the biosphere overlaps virtually the entire hydrosphere and portions of the atmosphere and outer lithosphere.
Industry:Science
The name given to the electrons originating at the cathodes of gaseous discharge devices. The term has now been extended to include low-pressure devices such as cathode-ray tubes. Furthermore, cathode rays are now used to designate electron beams originating from thermionic cathodes, whereas the term was formerly applied only to cold-cathode devices.

The oldest archeological cultures of the New World, the ancestors of modern Native Americans, are termed Paleoindian. These colonizing populations of the Americas were <i>Homo sapiens sapiens</i> who arrived during the late Pleistocene (Ice Age) from Asia, though precisely when, and whether in a single or multiple pulses of migration, are not yet known.
Industry:Science
The process of producing organoboranes by the addition of diborane to unsaturated organic compounds. In ether solvents the addition of diborane to such molecules is exceedingly rapid and essentially quantitative. This reaction therefore makes the organoboranes readily available. Such organoboranes find application as intermediates for organic synthesis.
Industry:Science
The science of the chemistry of the universe, particularly that beyond the Earth. As currently practiced, cosmochemistry is concerned primarily with inferences on pre-solar-system events, solar nebular processes, and early planetary processes as deduced from minerals in meteorites and from chemical and isotopic compositions of meteorites and their parts.
Industry:Science
The study of gases in motion. In general, matter exists in any of three states: solid, liquid, or gas. Liquids are incompressible under normal conditions; water is a typical example. In contrast, gases are compressible fluids; that is, their density varies depending on the pressure and temperature. The air surrounding a high-speed aircraft is an example.
Industry:Science
The third largest order of insects, containing the sawflies, ants, wasps, bees, and related forms. There are some 15,700 described species, subspecies, and varieties from America north of Mexico. Conservative estimates suggest that the world fauna may comprise well over 100,000 described species of this order, with many thousands still to be described.
