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.
Antibody proteins that bind to a specific target molecule (antigen) at one specific site (antigenic site). Monoclonal antibodies are produced by a laboratory culture of cells (a cell line), grown from a single antibody-secreting cell. Development of the technology for making monoclonal antibodies has had an impact in both science and medicine; applications include experiments in basic immunology, medical diagnostics, and therapeutics.

Characterization of tissue mechanical properties, particularly the elasticity or tactile stiffness of tissue, has important medical applications because these properties are closely linked to tissue health. Palpation is a traditional example by which abnormal tissue is detected through sensing its stiffness with touch. However, palpation is subjective and may not be feasible when the target region of evaluation is deep within the body.

Electronegativity, according to L. Pauling, is “the power of an atom in a molecule to attract electrons to itself.” With the concept of electronegativity, a vast number of observations of chemical and physical properties have been either correlated or predicted. Quantitative definitions and scales of electronegativity have been based not on electron distribution itself but on properties which were assumed to reflect electronegativity.
Industry:Science
Any of a group of diseases involving connective tissue; formerly termed collagen vascular disease. These diseases are clinically and pathologically discrete but have overlapping features. The group includes lupus erythematosus, systemic vasculitis, scleroderma (and systemic sclerosis), polymyositis, and Sjögren's syndrome. Each of the diseases can involve multiple organ systems and is often coupled with various immunologic abnormalities.

Devices that use the fact that the polarization in any real medium is a nonlinear function of the optical field strength to implement various useful functions. The nonlinearities themselves can be grouped roughly into second-order and third-order. Materials that possess inversion symmetry typically exhibit only third-order nonlinearities, whereas materials without inversion symmetry can exhibit both second- and third-order nonlinearities.

In 2001, space flight continued its momentum of preceding years, with extraordinary activity in the exploration, utilization, and commercialization of space. However space endeavors did occur at a considerably reduced rate. Launch activity in 2001 reached its lowest point since 1963, with only 57 flights successfully placing payloads into orbit, compared to 81 in the preceding year. There were two launch failures (down from four in 2000).
Industry:Science
Any of several elementary machines, one or more of which is found in practically every machine. The group of simple machines usually includes only the lever, wheel and axle, pulley (or block and tackle), inclined plane, wedge, and screw. However, the gear drive and hydraulic press may also be considered as simple machines. The principles of operation and typical applications of simple machines depend on several closely related concepts.
Industry:Science
Common name for a member of the family Macropodidae, the largest living marsupials. The 61 species in this family also include the wallabies, wallaroos, quokka, and pademelons. In Australia, the term kangaroo is applied only to the largest species of kangaroos, while all small and medium-sized ground-dwelling kangaroos are called wallabies. Except for their size, wallabies are practically the same as kangaroos in appearance as well as habits.
Industry:Science
Impaired health caused by a dietary deficiency, excess, or imbalance. To support human life, energy (from fat, carbohydrate, and protein), water, and more than 40 different food substances must be obtained from the diet in appropriate amounts. Malnutrition can result from the chronic intake of any of these substances at levels above, as well as below, ranges that are adequate and safe, but commonly, the term refers only to deficient intake.
Industry:Science
Defined narrowly, a science that is concerned with the nature and arrangement of horizons in soil profiles; the physical constitution and chemical composition of soils; the occurrence of soils in relation to one another and to other elements of the environment such as climate, natural vegetation, topography, and rocks; and the modes of origin of soils. Pedology so defined does not include soil technology, which is concerned with uses of soils.
