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.
Over the past few years, there has been keen worldwide interest in smart metering. In Europe, this interest has been strongly motivated by the European Union (EU) Energy Efficiency Directive, which among other things aims to minimize the environmental impacts of energy generation and to meet the commitments made on climate change under the Kyoto Protocol.
Industry:Science
One of a group of layer silicate minerals, usually green in color, characterized by a perfect cleavage parallel to (001). The cleavage flakes are flexible but inelastic, with a luster varying from pearly or vitreous to dull and earthy. The hardness on the cleavage is about 2.5. The specific gravity varies between 2.6 and 3.3 as a function of composition.
Industry:Science
Solid solutions of magnesium and aluminum, zinc, manganese, silicon, zirconium, rare-earth metals, thorium, or yttrium. The specific gravity of magnesium alloys ranges from 1.74 to 1.83. This low specific gravity has led to a great many structural applications in the aircraft, transportation, materials-handling, and portable-tool and -equipment industries.

Lipids form a class of compounds composed of neutral fats (triglycerides), phospholipids, glycolipids, sterols, and fat-soluble vitamins (A, D, E, and K). As a group they share the common physical property of insolubility in water. This article describes the assimilation of dietary lipids and the synthesis and degradation of lipids by the mammalian organism.
Industry:Science
Minute corrugations of the skin. They compose a sculpturing, termed dermatoglyphics, which characterizes the palmar and plantar surfaces of humans and the nonhuman primates. These areas lack hair and sebaceous (oil) glands, but sweat glands are numerous. In certain kinds of monkeys, a portion of the undersurface of the tail bears similarly specialized skin.

Like other jellyfish, the box jellyfish have neither a head nor a central brain; but unlike other jellyfish, they have well-developed eyes and display visually guided behavior. Recent findings on their optics indicate that they are at an early phase of eye evolution, where excellent visual performance does not have the same meaning as it does in other animals.

Pluto is both a dwarf planet and a member of the Kuiper Belt, a disk of small planets and planetesimals that surrounds the solar system beyond the orbit of Neptune. The population of dwarf planets far outnumbers the population of large planets, and teaches us that solar system formation predominantly creates small planets, not large planets, as had been thought.
Industry:Science
Solvent removal from the frozen state by sublimation; commonly referred to as freeze-drying. The dried material, a porous solid, is sealed under vacuum or inert-gas atmosphere and retains its physical and biological characteristics indefinitely. When reconstituted for use, the porous product readily readmits solvent; hence the term lyophile, or solvent-loving.
Industry:Science
Literally, a swelling; in the past the term has been used in reference to any swelling of the body, no matter what the cause. Thus a swollen region produced by edema, congestion, or hemorrhage into a tissue has been called a tumor. However, the word is now being used almost exclusively to refer to a neoplastic mass, and the more general usage is being discarded.
Industry:Science
Most cars are powered by gasoline or diesel fuel. There is a massive infrastructure of service stations to provide these fuels in most regions of the world, especially in areas where there are many cars. In the United States alone there are approximately 120,000 service stations, often clustered in larger cities and distributed along interstate and other highways.
