| combustion analysis | <technique> A method for determining the chemical composition of a compound by burning the compound under controlled conditions. Often used to determine the relative amounts of carbon and hydrogen in a compound. (09 Oct 1997) |
|---|---|
| multivariate analysis | A set of techniques used when variation in several variables has to be studied simultaneously. In statistics, multivariate analysis is interpreted as any analytic method that allows simultaneous study of two or more dependent variables. (12 Dec 1998) |
| 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) |
| cost-benefit analysis | A method of comparing the cost of a program with its expected benefits in dollars (or other currency). The benefit-to-cost ratio is a measure of total return expected per unit of money spent. This analysis generally excludes consideration of factors that are not measured ultimately in economic terms. Cost effectiveness compares alternative ways to achieve a specific set of results. (12 Dec 1998) |
| costs and cost analysis | Absolute, comparative, or differential costs pertaining to services, institutions, resources, etc., or the analysis and study of these costs. (12 Dec 1998) |
| half-tetrad analysis | <genetics> The analysis of tetrad chromosomes (a pair of homologous chromosomes, thus four total chromosomes) after recombination when only half of the tetrad (two of the four chromosomes) can be analysed. (13 Nov 1997) |
| predisposition analysis | <genetics> The analysis of how some people are more likely to get certain diseases as a result of their genetic make-up. (31 Dec 1997) |
| saturation analysis | General term for an assay in which a binder competes for labelled versus unlabelled ligand; following separation of free and bound ligand, the ligand (the analyte assayed) is quantitated by relating bound and unbound ratios to known standards. See: enzyme-linked immunosorbent assay, radioreceptor assay, immunoassay, enzyme-multiplied immunoassay technique, radioimmunoassay. Synonym: displacement analysis, saturation analysis. (05 Mar 2000) |
| proximate analysis | An analysis which reports volatile matter, fixed carbon, moisture content, and ash present in a fuel as a percentage of dry fuel weight. (05 Dec 1998) |
| segregation analysis | In genetics, the enumeration of progeny according to distinct and mutually exclusive phenotypes; used as a test of a putative pattern of inheritance, e.g., mendelian, dominant autosomal, epistatic, age-dependent. (05 Mar 2000) |
| self-analysis | Attempted analysis, or psychoanalysis, of one's self. Synonym: self-analysis. (05 Mar 2000) |
| semen analysis | <gynaecology> Laboratory examination of semen to check the quality and quantity of sperm. (09 Oct 1997) |
| sequence analysis | A multistage process that includes the determination of a sequence (protein, carbohydrate, etc.), its fragmentation and analysis, and the interpretation of the resulting sequence information. This information is useful in that it: 1) reveals the similarities of homologous genes, thereby providing insight into the possible regulation and functions of these genes; and 2) leads to a better understanding of disease states related to genetic variation. New sequencing methodologies, fully automated instrumentation, and improvements in sequencing-related computational resources contribute to the potential for genome-size sequencing projects. (12 Dec 1998) |
| sequence analysis, DNA | A multistage process that includes DNA cloning, physical mapping, subcloning, sequencing, and information analysis. New technological advances have led to the automation of certain steps in this process and contribute to the potential for large-scale DNA sequencing efforts. (12 Dec 1998) |
| sequence analysis, RNA | A multistage process that includes RNA cloning, physical mapping, subcloning, sequencing, and information analysis. (12 Dec 1998) |
