An annular coral reef, with or without small islets, that surrounds a lagoon without projecting land area.
Industry:Science
An anomalous rise in water elevations caused by severe storms approaching the coast. A storm surge can be succinctly described as a large wave that moves with the storm that caused it. The surge is intensified in the nearshore, shallower regions where the surface stress caused by the strong onshore winds pile up water against the coast, generating an opposing pressure head in the offshore direction. However, there are so many other forces at play in the dynamics of the storm surge phenomenon, such as bottom friction, Earth's rotation, inertia, and interaction with the coastal geometry, that a simple static model cannot explain all the complexities involved. In fact, the problem of predicting storm surges is so complex that scientists and engineers have dedicated many years in the development and application of sophisticated computer models to accurately predict the effects of storm surges.
Industry:Science
An antibody that reduces or abolishes some biological activity of a soluble antigen or of a living microorganism. Thus, diphtheria antitoxin is a neutralizing antibody that, in adequate amounts, abolishes the pathological effects of diphtheria toxin in animals. This is only one characteristic; the other general properties of the antibody are those of the immunoglobulin family (IgG, IgA, or IgM) to which it belongs.
Industry:Science
An antibody that will combine with and generally neutralize a particular toxin. When the manifestations of a disease are caused primarily by a microbial toxin, the corresponding antitoxin, if available in time, may have a pronounced prophylactic or curative effect. Apart from this, the other properties of an antitoxin are those of the antibody family (IgG, IgA, IgM) to which it belongs.
Industry:Science
An antigenically distinct member of the herpesvirus group of viruses, whose genome is deoxyribonucleic acid (DNA). Under electron-microscopic observation, the mature virus is indistinguishable in size and structure from the other human herpesviruses; that is, it has a nucleocapsid about110 nanometers in diameter, and when an envelope is present, the particle diameter is about 180 nm. The 78-nm central core, which is often observed in other herpesviruses, is not clearly visible in Epstein-Barr (EB) particles within infected cells, and few of the intracellular particles possess an envelope. Only about 10% of the extracellular virus particles are enveloped.
Industry:Science
An anxiety disorder in some individuals who have experienced an event that poses a direct threat to the individual's or another person's life. The characteristic features of anxiety disorders are fear, particularly in the ongoing absence of a real-life threat to safety, and avoidance behavior.
Industry:Science
An aphanitic (microscopically crystalline) to very fine-grained igneous rock, with more or less altered appearance, resembling basalt but composed of albite or oligoclase, chlorite, epidote, calcite, and actinolite.
Industry:Science
An apparatus consisting of an energy source, a method of converting that energy to heat, and a transport system to convey the energy and heat to the point of use. Most heating systems include some manual or automatic method of controlling the heat output and delivery.
Industry:Science
An apparatus used widely for countercurrent contacting of vapor and liquid to effect separations by distillation or absorption. In general, the apparatus consists of a cylindrical vessel with internals designed to obtain multiple contacting of ascending vapor and descending liquid, together with means for introducing or generating liquid at the top and vapor at the bottom.
Industry:Science
An apparatus with which force is measured between current-carrying conductors. The purpose of the measurement was to establish the value of the ampere in terms of its International System (SI) definition; therefore the relative locations of the conductors had to be measured so that the force between them could be computed from their geometry. The difficulty of this measurement limited the accuracy of even the best instruments to a few parts in a million. Therefore, current balances have now been superseded by other methods.
