| leg length inequality | A condition in which one of a pair of legs fails to grow as long as the other. (12 Dec 1998) |
| length | 1. The longest, or longer, dimension of any object, in distinction from breadth or width; extent of anything from end to end; the longest line which can be drawn through a body, parallel to its sides; as, the length of a church, or of a ship; the length of a rope or line. 2. A portion of space or of time considered as measured by its length; often in the plural. "Large lengths of seas and shores." (Shak) "The future but a length behind the past." (Dryden) 3. The quality or state of being long, in space or time; extent; duration; as, some sea birds are remarkable for the length of their wings; he was tired by the length of the sermon, and the length of his walk. 4. A single piece or subdivision of a series, or of a number of long pieces which may be connected together; as, a length of pipe; a length of fence. 5. Detail or amplification; unfolding; continuance as, to pursue a subject to a great length. "May Heaven, great monarch, still augment your bliss. With length of days and every day like this." (Dryden) 6. Distance. "He had marched to the length of Exeter." (Clarendon) at length. At or in the full extent; without abbreviation; as, let the name be inserted at length. At the end or conclusion; after a long period. See Syn. Of At last, under Last. At arm's length. See Arm. Origin: OE. Lengthe, AS. Leng, fr. Land, long, long; akin to D. Lengte, Dan. Laengde, Sw.

| length-breadth index | The ratio of the maximal breadth to the maximal length of the head, obtained by the formula: (breadth × 100)/length. Synonym: length-breadth index. (05 Mar 2000) |
| length-height index | The relation of the height to the length of the skull: (height × 100)/length. Synonym: height-length index, length-height index, transversovertical index. (05 Mar 2000) |
| length of stay | The period of confinement of a patient to a hospital or other health facility. (12 Dec 1998) |
| anovulatory cycle | A sexual cycle in which no ovum is discharged. (05 Mar 2000) |
| Born-Haber cycle | <physics> This is a mathematical description of the relationship between the electron affinity, heats of atomisation, ionisation energy and lattice energy of ionic compounds. (09 Oct 1997) |
| bottoming cycle | A cogeneration system in which steam is used first for process heat and then for electric power production. (05 Dec 1998) |
| brain wave cycle | The complete upward and downward excursion of a single wave, complex, or impulse as seen on an electroencephalogram. (05 Mar 2000) |
| c3 cycle | <biochemistry> The part of the photosynthesis process where carbon dioxide is converted into three-carbon compounds, which can then be turned into six-carbon sugars. (07 Nov 1997) |
| c4 cycle | <plant biology> An alternative, very efficient pathway used by plants living in areas with low levels of carbon dioxide, to convert carbon dioxide into a form usable by the plants during photosynthesis. (09 Oct 1997) |
| Calvin Benson cycle | <biochemistry, plant biology> Metabolic pathway responsible for photosynthetic carbon dioxide fixation in plants and bacteria. The enzyme that fixes carbon dioxide is RuDP carboxylase. The cycle is the only photosynthetic pathway in C3 plants and the secondary pathway in C4 plants. The enzymes of the pathway are present in the stroma of the chloroplast. (18 Nov 1997) |
| calvin cycle | In plants, a cyclical series of carbon-fixing, sugar-producing reactions in the chloroplasts. Some of the sugars (triose phosphates) are recycled, others are stored as carbohydrates. Light is not needed for these reactions, they use the carbon dioxide and energy produced in the light reactions of photosynthesis. (09 Oct 1997) |
| carbon dioxide cycle | First, an organism which can photosynthesise (such as a plant or some bacteria) will absorb carbon dioxide (CO2) from the air and incorporate it into its body or turn it into organic matter. Then, other organisms which cannot photosynthesise will eat the organic matter, or the photosynthesising organism, and release carbon dioxide gas as a waste product back into the air. (09 Oct 1997) |
