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.
The technological area involving the manipulation of voltages and electric currents through the use of various devices for the purpose of performing some useful action with the currents and voltages. This large field is generally divided into two primary areas, analog electronics and digital electronics.
Industry:Science
The planning and implementation of sustainable production of forest crops and other forest resources and uses. Key decisions include land allocation to different uses or combination of uses, silvicultural method and practices, intensity of management, timber harvest scheduling, and environmental protection.
Industry:Science
The scientific discipline that deals with understanding how rocks deform and fail due to natural and human-induced forces at scales ranging from micrometers to kilometers. Rock mechanics is also the engineering discipline for designing and stabilizing underground and surface excavations and rock foundations.
Industry:Science
The study of the propagation of light, and associated phenomena, in crystalline solids. The propagation of light in crystals can actually be so complicated that not all the different phenomena are yet completely understood, and not all theoretically predicted phenomena have been demonstrated experimentally.
Industry:Science
The process whereby a bulk liquid is transformed into a multiplicity of small drops. This transformation, often called primary atomization, proceeds through the formation of disturbances on the surface of the bulk liquid, followed by their amplification due to energy and momentum transfer from the surrounding gas.
Industry:Science
The name applied to arthropods in sections Anomura and Brachyura of the reptantian suborder of the order Decapoda, class Crustacea. The term crab is also sometimes used for two species of sucking lice (order Anoplura) which prey upon humans. <i>Phthirus pubis</i> is the crab louse which inhabits the pubic region.
Industry:Science
The time rate of change of position of a body without regard to direction. It is the numerical magnitude of a velocity and hence is a scalar quantity. Linear speed is commonly measured in such units as meters per second, miles per hour, or feet per second. It is the most frequently mentioned attribute of motion.
Industry:Science
The study of the structure and chemical composition of tissues of animals and plants as related to their function. The primary aim is to understand how tissues are organized at all structural levels, including the molecular and macromolecular, the entire cell and intercellular substances, and the tissues and organs.
Industry:Science
The radiological imaging of breast tissue. This procedure is used to identify cancer, preferably when still impalpable. Because of improved resolution in high-contrast film, only minor exposure of skin to x-rays is required, so that national screening programs have been set up in many western industrialized countries.
Industry:Science
The potential difference through which a bound electron must be raised to free it from the atom or molecule to which it is attached. In particular, the ionization potential is the difference in potential between the initial state, in which the electron is bound, and the final state, in which it is at rest at infinity.
