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 umbrella concept in the common language, typically defined by instantiation by reference to a variety of mental and behavioral states. These range from lust to a sense of liking, from joy to hostile aggression, and from esthetic appreciation to disgust. Emotions are usually considered to be accompanied by some degree of internal, frequently visceral, excitement, as well as strong evaluative components. Emotions are also often described as irrational, that is, not subject to deliberative cogitation, and as interfering with normal thought processes.

Any member of the fish family Gasterosteidae, order Gasterosteiformes. The body may be elongate, naked, or with bony scutes along the sides. Three to 16 well-developed isolated dorsal spines precede a normal dorsal fin having 6 to 14 rays. Additional identifying features are as follows: 12 or 13 caudal fin rays; a single spine and 1 or 2 soft rays in the pelvic fin; 3 branchiostegal rays; circumorbital ring incomplete posteriorly; epineurals present; and 28 to 42 vertebrae. A maximum length of about 18 cm (7 in.) is reached in <i>Spinachia spinachia</i>.

Any observable attribute of rocks, such as overall appearance, composition, or conditions of formation, and changes that may occur in these attributes over a geographic area. The term “facies” is widely used in connection with sedimentary rock bodies, but is not restricted to them. In general, facies are not defined for sedimentary rocks by features produced during weathering, metamorphism, or structural disturbance. In metamorphic rocks specifically, however, facies may be identified by the presence of minerals that denote degrees of metamorphic change.

In a mechanical system the condition under which no acceleration takes place. Newtonian mechanics today is based upon two definitions which modify, but are essentially equivalent to, Newton's three fundamental laws. These definitions postulate the action of forces on particles. A particle is defined as a conceptual volume element that has mass and is sufficiently small to have point location. A body is defined as a system of particles. To develop the mechanics of a body, these definitions are applied to each of its particles and their influences summed.

In 2001 an unusual squid estimated at 7 m (23 ft) in length was reported for the first time. That such a large animal could have gone undetected for so long seems remarkable. This squid, however, was found in the bathypelagic zone of the deep sea, a region that, because of its large size and inaccessibility, has been poorly investigated. The ocean has about 300 times more living space than exists on land. Over two-thirds of this vast aquatic realm lies in the bathypelagic zone, generally ranging from approximately 1000 m (3280 ft) deep down to the ocean floor.

Any of the mold-produced substances that may be injurious to vertebrates upon ingestion, inhalation, or skin contact. The diseases they cause, known as mycotoxicoses, need not involve the toxin-producing fungus. Diagnostic features characterizing mycotoxicoses are the following: the disease is not transmissible; drug and antibiotic treatments have little or no effect; in field outbreaks the disease is often seasonal; the outbreak is usually associated with a specific foodstuff; and examination of the suspected food or foodstuff reveals signs of fungal activity.

Factors of evolution observed today, such as natural selection, migration, and the origin and extinction of species, have operated throughout the history of life, but the characteristic rates of these processes have varied greatly over time and from one group of organisms to another. Because of this variation, evolutionary patterns seen in the fossil record are highly episodic and irregular. Paleontological studies of biological diversity seek to document this nonuniformity and to understand it in the context of geological, environmental, and ecological change.
Industry:Science
Hundreds and possibly thousands of different types of viruses are capable of infecting humans. Viruses are obligate parasites that must enter host cells to replicate. Because of their relatively simple structures, they replicate rapidly (generally in less than a day, sometimes in 2 to 3 h) and prolifically (each infected cell produces 100–10,000 new viruses). The combination of a low fidelity of replicating their genetic information, and, with some viruses, the ability to incorporate host genes into their own genome results in an extraordinary ability to mutate.
Industry:Science
Any separation technique in which a supercritical fluid is used as the mobile phase. For any fluid, a phase diagram can be constructed to show the regions of temperature and pressure at which gases and liquids, gases and solids, and liquids and solids can coexist. For the gas–liquid equilibrium, there is a certain temperature and pressure, known as the critical temperature (<i>T</i><sub><i>c</i></sub>) and pressure (<i>P</i><sub><i>c</i></sub>), below which a gas and a liquid can coexist but above which only a single phase (known as a supercritical fluid) can form.

Bedbugs have been reported from all types of accommodations, including sleeper coaches in trains, camper vans, ships, dormitories, and rooms in hotels and hostels of any standard. Despite the absence of evidence that bedbugs are related to poor hygiene or low socioeconomic status and despite many dozens of studies proving the absence of disease transmission, bedbugs have retained their stigma of poverty, filth, disgust, and disease. The associated shame by human hosts now partly prevents the analysis of why bedbugs are currently spreading and increasing in numbers.
