| Reynolds number | A dimensionless number that describes the tendency for a flowing fluid, such as blood, to change from laminar flow to turbulent flow or vice versa. (05 Mar 2000) |
|---|---|
| Reynold's number | <physiology> A constant without dimensions that relates the inertial and viscous drag acting to hinder a body moving through fluid medium. For cells the Reynold's number is very small, viscous drag is dominant and inertial resistance can be neglected. (18 Nov 1997) |
| MIM number | The catalog assignment for a mendelian trait in the MIM system. If the initial digit is 1, the trait is deemed autosomal dominant; if 2, autosomal recessive; if 3, then X-linked. Wherever a trait defined in this dictionary has a MIM number the number from the tenth edition of MIM is given in square brackets with or without an asterisk as appropriate e.g., Pelizaeus-Merzbacher disease is a well-established, autosomal, dominant, mendelian disorder.

| wave number | <microscopy> The number of waves or cycles of light flux or radiant energy, measured through a distance of 1 cm. (05 Aug 1998) |
| writhing number | <molecular biology> The number of times the axis of a DNA helix crosses itself while the molecule is in the process of supercoiling. (09 Oct 1997) |
| copy number | The number of molecules of a particular type on or in a cell or part of a cell. Usually applied to specific genes or to plasmids within a bacterium. (18 Nov 1997) |
| Polenske number | The number of milliliters of 0.1 n KOH required to neutralise the nonvolatile fatty acids obtained from 5 g of a saponified fat or oil. (05 Mar 2000) |
| CT number | A normalised value of the calculated X-ray absorption coefficient of a pixel (picture element) in a computed tomogram, expressed in Hounsfield units, where the CT number of air is -1000 and that of water is zero. Synonym: Hounsfield number. (05 Mar 2000) |
| haploid number | <cell biology, genetics> The haploid number is the total number of chromosomes in a single set, such as would be found in a gamete or a haploid somatic cell (such as in fungus or gametophyte plants). In humans, the haploid number would be 23. (09 Oct 1997) |
| Hehner number | The weight or percentage of the nonvolatile fatty acids yielded by 5 g of a saponified fat or oil. Synonym: Hehner value. (05 Mar 2000) |
| saponification number | The number of milligrams of KOH required to saponify 1 g of fat; an approximate measure of the average molecular weight of a fat, with which it varies inversely. Synonym: Koettstorfer number. (05 Mar 2000) |
| Hogben number | Unique personal identifying number constructed by using a sequence of digits for birth date, sex, birthplace, and other identifiers; invented by and named for Lancelot Hogben, British mathematician; Hogben numbers are the basis for identification numbers in many primary care facilities and are used in many record linkage systems. (05 Mar 2000) |
| Hounsfield number | A normalised value of the calculated X-ray absorption coefficient of a pixel (picture element) in a computed tomogram, expressed in Hounsfield units, where the CT number of air is -1000 and that of water is zero. Synonym: Hounsfield number. (05 Mar 2000) |
| hydrogen number | The quantity of hydrogen that 1 g of fat will absorb; it is a measurement of the amount of unsaturated fatty acids in the fat. See: iodine number. (05 Mar 2000) |
| stoichiometric number | The number associated with a reactant or product participating in a defined chemical reaction; usually an integer. (05 Mar 2000) |
