| colligation | 1. A combination in which the components are distinguishable from one another. 2. The bringing of isolated events into a unified experience. Origin: L. Cum, together, + ligo, to bind (05 Mar 2000) |
|---|---|
| colligative | 1. Depending on numbers of particles. 2. Referring to properties of solutions that depend only on the concentration of dissolved substances and not on their nature (e.g., osmotic pressure, elevation of boiling point, vapor pressure lowering, freezing point depression). (05 Mar 2000) |
| colligative properties | <chemistry> Properties (such as freezing-point depression) of solutions that vary according to how much solute is in the solution. (09 Oct 1997) |
| collimating lens | <physics> A lens used to produce a collimated beam from a light source. With a true point source on the axis the beam would be an axial tube of parallel rays With practical sources having real area the beam will be a diverging cone of parallel rays from each light point, this beam still has special properties and can be collected again by a good lens. (05 Aug 1998) |
| collimation | <microscopy> The operation of controlling a beam of radiation so that if the light source were a point, the light rays would become parallel. The total bundle of rays diverge as the source size increases. (05 Aug 1998) |
| collimator | A device of high absorption coefficient material used in collimation. (05 Mar 2000) |
| collinearity | The phenomona that the orderings of the corresponding elements of DNA, the RNA transcribed from it, and the amino acid translated from the RNA are identical. Origin: L. Collineo, to direct in a straight line (05 Mar 2000) |
| Collins, Edward Treacher | <person> English ophthalmologist, 1862-1919. See: Treacher Collins' syndrome. (05 Mar 2000) |
| colliotomy | An obsolete term for adhesiotomy. Origin: G. Kolla, glue, + G. Tome, incision (05 Mar 2000) |
| Collip, James | <person> Canadian endocrinologist, 1892-1965. See: Noble-Collip procedure, Anderson-Collip test. (05 Mar 2000) |
| colliquation | 1. Excessive discharge of fluid. 2. Liquidification in the process of necrosis. Origin: L. Col-, together, + liquo, pp. Liquatus, to cause to melt (05 Mar 2000) |
| colliquative | Denoting or characteristic of colliquation. (05 Mar 2000) |
| colliquative albuminuria | An albuminuria that is at first slight in degree, but unexpectedly becomes greatly increased during convalescence from highly febrile disease, e.g., typhoid fever. (05 Mar 2000) |
| colliquative degeneration | An obsolete term for liquefaction degeneration. (05 Mar 2000) |
| colliquative diarrhoea | Diarrhoea associated with excessive discharge of fluid. (05 Mar 2000) |
