Glycoprotein or protein molecules synthesized by polar and north temperate fishes to enable them to survive in freezing seawater. Similar antifreezes are found in some insects, but relatively little is known about their structure and function.
Industry:Science
Any clouding or opacity of the crystalline lens of the eye. Cataracts vary markedly in degree of density and may be due to many causes, but the majority are associated with aging. Cataracts are the single leading cause of blindness in the world.
Industry:Science
Application of engineering principles to the solution of forestry problems, such as those dealing with harvesting, forest transportation, materials handling, and mechanical silviculture, with regard to long-range environmental and economic effects.
Industry:Science
Any gem variety of the mineral corundum (Al<sub>2</sub>O<sub>3</sub>), except those called ruby because of their medium- to dark-red color. Sapphire has a hardness of 9 (Mohs scale), a specific gravity near 4.00, and refractive indices of 1.76–1.77.
Industry:Science
Compound wireless services (patent pending) represent a future family of services for wireless devices that will evolve from mobile or wireless telephones. These services will have a greater effect on people's lives than current mobile telephones do.
Industry:Science
Consciousness is central to human existence, yet it has proved difficult to define and characterize. A useful criterion in humans is as follows: if one can communicate with others about an event or a perception, it is conscious; otherwise, it is not.
Industry:Science
Devices that serve to vary some property of a light beam. The direction of the beam may be scanned as in an optical deflector, or the phase or frequency of an optical wave may be modulated. Most often, however, the intensity of the light is modulated.
Industry:Science
Heartworm (<i>Dirofilaria immitus</i>) is a nematode parasite that resides within the host's large pulmonary arteries and right heart chambers. It primarily infests dogs but may also infest foxes, wolves, coyotes, ferrets, sea lions, horses, and cats.
Industry:Science
Either highly energetic collisions of elementary particles, namely, leptons and nucleons, which probe the nucleons' internal structure; or collisions between two heavy ions in which the two nuclei interact strongly while their nuclear surfaces overlap.
Industry:Science
Any interaction between particles, aggregates of particles, or rigid bodies in which they come near enough to exert a mutual influence, generally with exchange of energy. The term collision, as used in physics, does not necessarily imply actual contact.
