| content analysis | Any of a variety of techniques for classification and study of the verbal products of normal or of psychologically disabled individuals. (05 Mar 2000) |
|---|
| AT content | <molecular biology> The percentage of nitrogenous bases on a DNA molecule which are either adenine or thymine (from a possibility of four different ones, also including cytosine and guanine). See: GC content. (09 Oct 1997) |
|---|---|
| carbon dioxide content | The total carbon dioxide available from serum or plasma following addition of acid; measured routinely in hospital laboratories as a component of electrolyte profiles. (05 Mar 2000) |
| GC content | <molecular biology> The percentage of nitrogenous bases on a DNA molecule which are either guanine or cytosine (from a possibility of four different ones, also including adenine and thymine). See: AT content. (20 Mar 1998) |
| manifest content | Those elements of fantasy and dreams which are consciously available and reportable. (05 Mar 2000) |
| moisture content | (MC) The weight of the water contained in wood, usually expressed as a percentage of weight, either oven-dry or as received. (05 Dec 1998) |
| content | 1. That which is contained within something else, usually in this sense in the plural form, contents. 2. In psychology, the form of a dream as presented to consciousness. 3. Ambiguous usage for concentration; e.g., blood haemoglobin content could mean either its concentration or the product of its concentration and the blood volume. Origin: L. Contentus, fr. Con-tineo, pp. -tentus, to hold together, contain (05 Mar 2000) |
| content validity | The extent to which the items of a test or procedure are in fact a representative sample of that which is to be measured; e.g., items relating to ability in arithmetic and defining words are appropriate content for an intelligence test. (05 Mar 2000) |
| latent content | The hidden, unconscious meaning of thoughts or actions, especially in dreams or fantasies. (05 Mar 2000) |
| accumulation analysis | A technique in which an intermediate of a metabolic pathway accumulates due to selective inhibition of a particular step in that pathway or in a mutant that is deficient in a certain step. The intermediate is then isolated, analyzed, and identified. (05 Mar 2000) |
| activation analysis | <radiobiology> Method for identifying and measuring chemical elements in a sample of material. Sample is first made radioactive by bombardment with neutrons, charged particles, or gamma rays. Newly formed radioactive atoms in the sample then give off characteristic radiations (such as gamma rays) that tell what kinds of atoms are present, and how many. (09 Oct 1997) |
| actuarial analysis | The application of probability and statistical methods to calculate the risk of occurrence of any event, such as onset of illness, recurrent disease, hospitalization, disability, or death. It may include calculation of the anticipated money costs of such events and of the premiums necessary to provide for payment of such costs. (12 Dec 1998) |
| amino acid analysis | Determination and identification of amino acid content of a macromolecule, identification of a specific amino acid in macromolecules, often a mutated protein, identification and quantitation of amino acid content in blood plasma or urine; a key diagnostic aid. (05 Mar 2000) |
| analysis | <technique> The separation into component parts or elements, the act of determining the component parts of a substance. Origin: Gr. Lysis = dissolution (18 Nov 1997) |
| analysis of variance | A statistical technique that isolates and assesses the contributions of categorical independent variables to variation in the mean of a continuous dependent variable. (12 Dec 1998) |
| base sequence analysis | <molecular biology> A method, sometimes automated, for determining the base sequence. (09 Oct 1997) |
