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.
Crohn's disease (CD) and ulcerative colitis (UC) are inflammatory disorders of the digestive tract that are characterized by abdominal pain, weight loss, malaise, and diarrhea. Although UC affects only the superficial lining of the colon and is continuous from the rectum proximally (toward the beginning of the colon), inflammation in CD can penetrate deep into the bowel wall and can present with multiple discontinuous lesions that affect both the small intestine and the large intestine.

Generally, environmental events of a challenging sort as well as the body's response to such events. Of particular interest has been the relationship between stress and the body's adaptation to it on the one hand and the body's susceptibility to disease on the other. Both outcomes involve behavioral and brain changes as well as psychosomatic events, that is, changes in body function arising from the ability of the brain to control such function through neural output as well as hormones.

By convention, the component present in the greatest proportion in a homogeneous mixture of pure substances (solutions). Components of mixtures present in minor proportions are called solutes. Thus, technically, homogeneous mixtures are possible with liquids, solids, or gases dissolved in liquids; solids in solids; and gases in gases. In common practice this terminology is applied mostly to liquid mixtures for which the solvent is a liquid and the solute can be a liquid, solid, or gas.

Disturbances in the structure and function of the skeletal system. The musculoskeletal system provides a rigid structural frame that permits locomotion through muscle action and aids in the functioning of the other organ systems. It also houses blood-forming marrow tissue and stores calcium, phosphorus, magnesium, and a variety of other ionic species. Bone is unique among the tissues of the body in that it responds to injury by re-forming itself identically over time, without scarring.

For flying, an upward lift force must be generated to overcome the weight of the aircraft, and the engines must generate a forward thrust force to overcome the drag force produced by the air flowing over the aircraft. These lift and drag forces are closely coupled, and an improvement in one can lead to benefits in the other. A principal contributor to the drag force is boundary-layer skin-friction drag, which results from friction forces generated as air passes over the aircraft surfaces.

Any substance that tends to maintain the physical and chemical properties of a material. Degradation, that is, irreversible changes in chemical composition or structure, is responsible for the premature failure of materials. Stabilizers are used to extend the useful life of materials as well as to maintain their critical properties above the design specifications. Oxygen and water are the principal degradants, but ultraviolet radiation also can have a significant effect (photodegradation).

Diseases and disturbances of the teeth and associated structures, including abnormal formation and growth of the teeth and jaws, tooth decay, inflammation of the tissues housing the roots of the teeth, and various diseases of the jaw bones. Tooth disorders are important because of their integral relationship to general body health, the essential role of the teeth in mastication and speech, and the contribution of normal dental function to the individual's psychological sense of well-being.

Geographic information systems (GIS) are software tools for storing, retrieving, mapping, and analyzing geographic data. Because paper maps depict geographic phenomena in two dimensions (2D), GIS were originally designed to handle 2D data and present visual images in 2D. The digital maps created and visualized with early GIS are thus basically similar to conventional paper maps. For several reasons, there has been dramatic development in three-dimensional (3D) GIS in the past 15 years or so.

In astronomy, the two points in an elliptical orbit that are closest to, and farthest from, the primary body about which the secondary revolves. In the orbit of a planet or comet about the Sun, the apsides are, respectively, perihelion and aphelion. In the orbit of the Moon, the apsides are called perigee and apogee, while in the orbit of a satellite of Jupiter, these points are referred to as perijove and apojove. The major axis of an elliptic orbit is referred to as the line of apsides.
Industry:Science
Any physical system that is bound to a position of stable equilibrium by a restoring force or torque proportional to the linear or angular displacement from this position. If such a body is disturbed from its equilibrium position and released, and if damping can be neglected, the resulting vibration will be simple harmonic motion, with no overtones. The frequency of vibration is the natural frequency of the oscillator, determined by its inertia (mass) and the stiffness of its restoring force.
