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 primary reserve polysaccharide of the animal world. It is found in the muscles and livers of all higher animals, as well as in the cells of lower animals. Because of its close relationship to starch, it is often called animal starch, although glycogen is found in some lower plants, fungi, yeast, and bacteria. A polysaccharide similar to glycogen was isolated in one case from a higher plant, Golden Bantam sweet corn (<i>Zea mays</i>).

The study of atomic masses has significantly contributed to understanding the basic properties of matter. The development of new and precise experimental methods in this field has led to an extension of knowledge far into the region of exotic nuclei and toward the limits of nuclear stability. This experimental progress is also reflected by a revolution in precision mass measurements by frequency analysis of stored and cooled exotic nuclei.

The study of fluids at rest; that is, at every point in the fluid, the velocity and acceleration are zero. The only force acting at a point on the surface of a small volume of fluid is due to the pressure at that point, and the force is perpendicular to the surface. Application of Newton's second law shows that the pressure is independent of the orientation of the surface on which it is acting, and that the pressure increases with depth.
Industry:Science
The measurement or estimation of temperatures at which geologic processes take place. Methods used can be divided into two groups, nonisotopic and isotopic. The isotopic methods involve the determination of distribution of isotopes of the lighter elements between pairs of compounds in equilibrium at various temperatures, and application of these data to problems of the temperature at which these compounds (commonly minerals) form in nature.

The mechanisms that ensure that particular cell types differentiate in the correct location within the embryo and that the layers of cells bend and grow in the correct relative positions. Pattern formation is one of four processes that underlie development, the others being growth, cell diversification, and morphogenesis. Pattern formation can more easily be understood by first briefly clarifying the importance of the other three processes.

The study of geological evidence for past earthquakes. This is a scientific discipline that has contributed greatly to modern understanding of the nature of earthquakes. The patterns of earthquakes, in both space and time, evolve over centuries and millennia and cannot be discovered by modern instruments. Knowledge of these patterns is important for understanding the physics of earthquakes and for forecasting future destructive earthquakes.
Industry:Science
The process of managing the timing and the quantities of goods to be ordered and stocked, so that demands can be met satisfactorily and economically. Inventories are accumulated commodities waiting to be used to meet anticipated demands. Inventory control policies are decision rules that focus on the trade-off between the costs and benefits of alternative solutions to questions of when and how much to order for each different type of item.

The mechanical excitation of an elastic medium. Originally, sound was considered to be only that which is heard. This admitted questions such as whether or not sound was generated by trees falling where no one could hear. A more mechanistic approach avoids these questions and also allows acoustic disturbances too high in frequency (ultrasonic) to be heard or too low (infrasonic) to be classed as extensions of those events that can be heard.
Industry:Science
The scientific study of past material culture. The initial objective of archeology is to construct cultural chronologies, attempting to order past material culture into meaningful temporal segments. The intermediate objective is to breathe life into these chronologies by reconstructing past lifeways. The ultimate objective of contemporary archeology is to determine the cultural processes that underlie human behavior, both past and present.

The last two decades have seen an unprecedented interest in understanding the medicinal properties of naturally occurring compounds. A wide variety of these agents are under scrutiny for their clinical potential in disease prevention and treatment. Among these compounds is a family of plant antibiotics (phytoalexins) named viniferin whose members exhibit strong antifungal properties. One remarkable compound in this family is resveratrol (RSV).
