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.
An insulated, cooled compartment. If it is large enough for the entry of a person, it is termed a walk-in box; otherwise it is called a reach-in refrigerator. Cooling may be by mechanical or gas refrigeration, by water or dry ice, or by brine circulation. Temperatures maintained depend upon the requirements of the product stored, generally varying from 55°F (13°C) down to 0°F (−18°C), and sometimes lower.
Industry:Science
An integrated arrangement of fixed facilities for protection from combustion by use of water extinguishment. The system comprises an adequate water supply, hydraulically designed internal piping, and sprinklers connected in a systematic pattern over the protected area; the system is activated by a fire to discharge a fine spray of water over the heat.
Industry:Science
An integrated device consisting of a biological recognition element and a transducer capable of detecting the biological reaction and converting it into a signal which can be processed. Ideally, the sensor should be self-contained, so that it is not necessary to add reagents to the sample matrix to obtain the desired response. There are a number of analytes (the target substances to be detected) which are measured in biological media: pH, partial pressure of carbon dioxide (pCO<sub>2</sub>), partial pressure of oxygen (pO<sub>2</sub>), and the ionic concentrations of sodium, potassium, calcium, and chloride. However, these sensors do not use biological recognition elements, and are considered chemical sensors. Normally, the biological recognition element is a protein or protein complex which is able to recognize a particular analyte in the presence of many other components in a complex biological matrix. Recently this definition has been expanded to include oligonucleotides. The recognition process involves a chemical or biological reaction, and the transducer must be capable of detecting not only the reaction but also its extent. An ideal sensor should yield a selective, rapid, and reliable response to the analyte, and the signal generated by the sensor should be proportional to the analyte concentration.
Industry:Science
An integrative science that studies the basic structural and functional relationships within and among living populations and their physical–chemical environments in marine ecosystems. Although an outgrowth of natural history and the life sciences, marine ecology draws on all the major fields within the biological sciences as well as oceanography, physics, geology, and chemistry.

An intelligence analyst's job is to answer policymakers' questions on a given subject. The questions may be broad and open-ended (for example: What economic factors shape the foreign policy of another country?) or they may be very specific (for example: Is a terrorist planning to strike a particular target?). Answering these questions often requires the analyst to predict future events. There are thousands of pieces of information available on each subject, and they invariably contain incomplete and contradictory evidence on the situation. Making reliable predictions with limited and contradictory evidence is an incredibly challenging task. Many analysts are turning to new graph-based analysis approaches to help them better make predictions. These new approaches are an interdisciplinary combination of mathematical graph theory, anthropology, and sociology.
Industry:Science
An intense columnar vortex (not necessarily containing a funnel-shaped cloud) of small horizontal extent, over water. Typical visible vortex diameters are of the order of 33 ft (10 m), but a few large waterspouts may exceed 330 ft (100 m) across. In the case of Florida waterspouts, only rarely does the visible funnel extend from parent cloudbase to sea surface. Like the tornado, most of the visible funnel is condensate. Therefore, the extension of the funnel cloud downward depends upon the distribution of ambient water vapor, ambient temperature, and pressure drop due to the vortex circulation strength.
Industry:Science
An intense irrational fear that often leads to avoidance of an object or situation. Phobias (or phobic disorders) are common (for example, fear of spiders, or arachnophobia; fear of heights, or acrophobia) and usually begin in childhood or adolescence. Psychiatric nomenclature refers to phobias of specific places, objects, or situations as specific phobias. About one in two individuals report that they are afraid of public speaking; in very severe cases, this is considered a form of social phobia. Social phobias also include other kinds of performance fears (such as playing a musical instrument in front of others; signing a check while observed) and social interactional fears (for example, talking to people in authority; asking someone out for a date; returning items to a store). Individuals who suffer from social phobia often fear a number of social situations.
Industry:Science
An intentional difference in sizes of two mating parts. With running or sliding fits, in which mating parts move relative to each other, allowance is a clearance, usually for a film of oil. In this sense, allowance is the space “allowed” for motion between parts. To avoid binding between parts, a minimum clearance is critical for a running fit.
Industry:Science
An interaction between two species that benefits both. Individuals that interact with mutualists experience higher sucess than those that do not. Hence, behaving mutualistically is advantageous to the individual, and it does not require any concern for the well-being of the partner. At one time, mutualisms were thought to be rare curiosities primarily of interest to natural historians. However, it is now believed that every species is involved in one or more mutualisms. Mutualisms are thought to lie at the root of phenomena as diverse as the origin of the eukaryotic cell, the diversification of flowering plants, and the pattern of elevated species diversity in tropical forests.
Industry:Science
An interconnection of electronic devices, an electronic device being an entity having terminals which is described at its terminals by electromagnetic laws. Most commonly these are voltage–current laws, but others, such as photovoltaic relationships, may occur.
