| stream class | Classification of streams based on the present and foreseeable uses made of the water, and the potential effects of on-site changes on downstream uses. Four classes are defined (05 Dec 1998) |
| stream-type fish | Fish that rear for a year or more in a stream. (09 Oct 1997) |
| two-stream amplifier | <radiobiology> Microwave amplifier based on the two-stream instability. (09 Oct 1997) |
| two-stream instability | <radiobiology> Instability which can develop when a stream of particles of one type has a velocity distribution with its peak well separated from that of another type of particle through which it is flowing. A stream of energetic electrons passing through a cold plasma can, for example: excite ion waves which will grow rapidly in magnitude at the expense of the kinetic energy of the electrons. (09 Oct 1997) |
| biological clock | <biology, physiology> An internal biological mechanism which controls certain biological rhythms and biocycles, such as metabolism, sleep cycles, photosynthesis. (21 Mar 1998) |
| circadian clock | <physiology> A biological timing mechanism that controls cell synchronisation (a entire population of cells divides simultaneously). (09 Oct 1997) |
| molecular clock | This term has two separate uses. 1. <molecular biology> The rate of fixation of mutations in DNA and thus times the rate of genetic diversification. 2. <cell biology> A biological system capable of maintaining up a timing rhythm or pulse. All such clocks are thought to be entrained by a natural oscillator such as the diurnal rhythm. (18 Nov 1997) |
| ten-o'clock | <botany> A plant, the star-of-Bethlehem. See Star. Source: Websters Dictionary (01 Mar 1998) |
| four-o'clock | 1. <botany> A plant of the genus Mirabilis. There are about half a dozen species, natives of the warmer parts of America. The common four-o'clock is M. Jalapa. Its flowers are white, yellow, and red, and open toward sunset, or earlier in cloudy weather; hence the name. It is also called marvel of Peru, and afternoon lady. 2. <zoology> The friar bird; so called from its cry, which resembles these words. Source: Websters Dictionary (01 Mar 1998) |
| lens clock | A device for measuring the radii of the curvature of a spectacle lens. Synonym: lens clock. Origin: Geneva, Switzerland (05 Mar 2000) |
