| melting | Liquefaction; the act of causing (something) to melt, or the process of becoming melted. <chemistry> Melting point, the degree of temperature at which a solid substance melts or fuses; as, the melting point of ice is 0 deg Centigrade or 32 deg Fahr, that of urea is 132 deg Centigrade. Melting pot, a vessel in which anything is melted; a crucible. Source: Websters Dictionary (01 Mar 1998) |
|---|---|
| melting point | The temperature at which a solid becomes a liquid, the temperature at which 50% of a macromolecule becomes denatured. (05 Mar 2000) |
| melting sign | <radiology> Regression of consolidation from periphery to centre, seen in pulmonary infarction, appears within days to weeks (12 Dec 1998) |
| melting temperature | The midpoint in the change in optical properties (absorbance, rotation) of a structured polymer (e.g., DNA) with increasing temperature. Synonym: melting temperature. (05 Mar 2000) |
| melting temperature of DNA | That temperature at which, under a given set of conditions, double-stranded DNA is changed (50%) to single-stranded DNA; under standard conditions, the base composition of the DNA can be estimated from the denaturation temperature, since the greater the denaturation temperature, the greater the guanine-plus-cytosine content (i.e., GC content) of the DNA. Synonym: melting temperature of DNA. (05 Mar 2000) |
| DNA melting | <molecular biology> Denaturation of a DNA molecule with heat. The double-stranded molecule breaks up into two single-stranded molecules as a result of heat. (09 Oct 1997) |
| thermal melting profile | In general a record of the phase state of a system over a temperature range. Phase changes can be detected by exothermy or endothermy. Valuable in studying lipid and DNA structures. (18 Nov 1997) |
| range | The set of conditions throughout which an organism (for example, plant species) naturally occurs. (09 Oct 1997) |
| range, normal | Normal results can fall outside the normal range. By convention, the normal range is set to cover ninety-five percent (95%) of values from a normal population. Five percent (5%) of normal results therefore fall outside the normal range. (12 Dec 1998) |
| range of accommodation | The distance between an object viewed with minimal refractivity of the eye and one viewed with maximal accommodation. (05 Mar 2000) |
| range of convergence | The distance between the near point and far point of convergence. Synonym: range of convergence. (05 Mar 2000) |
| range of motion | The range through which a joint can be moved, usually its range of flexion and extension. Due to an injury, the knee may for example lack 10 degrees of full extension. (12 Dec 1998) |
| range of motion, articular | Range through which a joint can be extended and flexed. This is frequently assessed following surgery of the joint. (12 Dec 1998) |
| motion, range of | The range through which a joint can be moved, usually its range of flexion and extension. Due to an injury, the knee may for example lack 10 degrees of full extension. (12 Dec 1998) |
| host range | The range of host species or cell types which a particular virus, bacteria, or parasite is able to infect or parasitise. (09 Oct 1997) |
