| limit | 1. That which terminates, circumscribes, restrains, or confines; the bound, border, or edge; the utmost extent; as, the limit of a walk, of a town, of a country; the limits of human knowledge or endeavor. "As eager of the chase, the maid Beyond the forest's verdant limits strayed." (Pope) 2. The space or thing defined by limits. "The archdeacon hath divided it Into three limits very equally." (Shak) 3. That which terminates a period of time; hence, the period itself; the full time or extent. "The dateless limit of thy dear exile." (Shak) "The limit of your lives is out." (Shak) 4. A restriction; a check; a curb; a hindrance. "I prithee, give no limits to my tongue." (Shak) 5. <logic> A determining feature; a distinguishing characteristic a differentia. 6. <mathematics> A determinate quantity, to which a variable one continually approaches, and may differ from it by less than any given difference, but to which, under the law of variation, the variable can never become exactly equivalent. Elastic limit. See Elastic. Prison limits, a definite, extent of space in or around a prison, within which a prisoner has liberty to go and come. Synonym: Boundary, border, edge, termination, restriction, bound, confine. Origin: From L. Limes, limitis: cf. F.limite; -or from E. Limit, v. See Limit. To apply a limit to, or set a limit for; to terminate, circumscribe, or restrict, by a limit or limits; as, to limit the acreage of a crop; to limit the issue of paper money; to limit one's ambitions or aspirations; to limit the meaning of a word. <astronomy> Limiting parallels, those parallels of latitude between which only an occultation of a star or planet by the moon, in a given case, can occur. Origin: F. Limiter, L. Limitare, fr. Limes, limitis, limit; prob. Akin to limen threshold, E. Eliminate; cf. L. Limus sidelong. Source: Websters Dictionary (01 Mar 1998) |
| limit dextrin | The polysaccharide fragments remaining at the end (limit) of exhaustive hydrolysis of amylopectin or glycogen by alpha-1,4-glucan maltohydrolase, which cannot hydrolyze the alpha-1,6 bonds at branch points; accumulates in individuals with type III glycogen storage disease. Synonym: dextrin limit. (05 Mar 2000) |
| limit dextrinase | <enzyme> An enzyme with action similar to that of isoamylase; it cleaves 1,6-alpha-glucosidic linkages in pullalan, amylopectin, and glycogen, and in alpha-and beta-amylase limit-dextrins of amylopectin and glycogen. Compare: isoamylase. Synonym: limit dextrinase, pullulanase, R enzyme. (05 Mar 2000) |
| limit dextrinosis | Glycogenosis due to amylo-1,6-glucosidase deficiency, resulting in accumulation of abnormal glycogen with short outer chains in liver and muscle. Synonym: Cori's disease, debranching deficiency limit dextrinosis, limit dextrinosis, Forbes' disease. (05 Mar 2000) |
| limit of resolution | 1. <optics> The resolution of an optical system defines the closest proximity of two objects that can be seen as two distinct regions of the image. This limit depends upon the Numerical Aperture of the optical system, the contrast step between objects and background and the shape of the objects. The often quoted Airy limit applies only to self luminous discs. 2. <genetics> The smallest map distance measurable by an experiment involving a certain number of classified recombinant progency.

| atomic number | <chemistry> Symbol Z. The number of protons in the nucleus of an atom and also its characteristic atomic number. The atomic numbers of the known elements form a complete series from 1 (hydrogen) to 103 (lawrencium). (16 Dec 1997) |
| Avogadro's number | <physics> The number of molecules in a mole (gram molecular weight) of a substance, equals 6.02 x 1023 molecules. (09 Oct 1997) |
| Brinell hardness number | A number related to the size of the permanent impression made by a ball indenter of specified size (usually 10 mm in diameter) pressed into the surface of the material under a specified load: where P = applied load in kg, D = diameter of the ball in mm, and d = diameter of the impression in mm.

| burst number | The number of viral particles that emerge from a cell after a viralinfection has burst it open. (09 Oct 1997) |
| Mach number | A number representing the ratio between the speed of an object moving through a fluid medium, such as air, and the speed of sound in the same medium. (05 Mar 2000) |
| magnetic mach number | <physics> A dimensionless number equal to the ratio of the velocity of a fluid to the velocity of Alfven waves in that fluid. (13 Nov 1997) |
| mass number | The mass of the atom of a particular isotope relative to hydrogen-1 (or to 1/12 the mass of carbon-12), generally very close to the whole number represented by the sum of the protons and neutrons in the atomic nucleus of the isotope (indicated in the name or symbol of the isotope; e.g., oxygen-16, 16O); not to be confused with the atomic weight of an element, which may include a number of isotopes in natural proportion.

| Reichert-Meissl number | An index of the volatile acid content of a fat; the number of milliliters of 0.1 n KOH required to neutralise the soluble volatile fatty acids in 5 g of fat that has been saponified, acidified to liberate the fatty acids, and then steam-distilled. Synonym: volatile fatty acid number. (05 Mar 2000) |
