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.
Scientists are carefully scrutinizing saponins, which exert a host of biological effects on humans, plants, and animals. The diversity of structures; the challenges of isolation; the pharmacological, biological, and agricultural activities already found and those still to be discovered; and the promise of commercialization are driving the study.
Industry:Science
Lithography is important in making integrated circuits. Semiconductor chips are the building blocks by which advances in communications and transportation are made possible in concert with software technology. The semiconductor chip comprises a silicon wafer printed by lithography equipment, similar in operation to the common photographic camera.
Industry:Science
In mammals, the interval between fertilization and birth. It covers the total period of development of the offspring, which consists of a preimplantation phase (from fertilization to implantation in the mother's womb), an embryonic phase (from implantation to the formation of recognizable organs), and a fetal phase (from organ formation to birth).
Industry:Science
Many plants are grown as fiber crops because of their content or yield of fibrous material which is used for many commercial purposes and for home industry. The production and use of plant fibers date back many centuries and form the basis for one of the earliest industrial processes. Fibers may be extracted from various parts of different plants.

Mobile satellite service (MSS) systems provide voice and data communications service to users over a wide area. MSS systems can serve a whole continent and its coastal waters via one or several Earth-orbiting satellites. In contrast, cellular communications systems use thousands of base transceiver stations to provide communications in desired areas.
Industry:Science
Nucleated, usually filamentous, sporebearing organisms devoid of chlorophyll; typically reproducing both sexually and asexually; living as parasites in plants, animals, or other fungi, or as saprobes on plant or animal remains, in aquatic, marine, terrestrial, or subaerial habitats. Yeasts, mildews, rusts, mushrooms, and truffles are examples of fungi.
Industry:Science
One of the three basic forces of nature, along with the strong nuclear interaction and the gravitational interaction. The terms “force” and “interaction between particles” are used interchangeably in this context. All of the known forces, such as atomic, nuclear, chemical, or mechanical forces, are manifestations of one of the three basic interactions.
Industry:Science
One of the three basic passive components of an electric circuit that displays a voltage drop across its terminals and produces heat when an electric current passes through it. The electrical resistance, measured in ohms, is equal to the ratio of the voltage drop across the resistor terminals measured in volts divided by the current measured in amperes.
Industry:Science
Injury to tissue by physical or chemical means. Mechanical injury includes abrasions, contusions, lacerations, and incisions, as well as stab, puncture, and bullet wounds. Trauma to bones and joints results in fractures, dislocations, and sprains. Head injuries are often serious because of the complications of hemorrhage, skull fracture, or concussion.
Industry:Science
Methods of chemical analysis in which analyte concentration is related to luminescence intensity or some other property of luminescence. Photoluminescence, particularly fluorescence, is the most widely used type of luminescence for chemical analysis. However, there are also important analytical applications of both chemiluminescence and bioluminescence.
