| horizontal survey | <epidemiology> A study of a community, perhaps stratified by age, sex, ethnicity etc., but at one point in time or over a short time interval. Although a snapshot, horizontal surveys of prevalence and intensity within different age classes of a community can nevertheless provide valuable information on the rate at which hosts acquire infection through time, provided that the host and parasite populations have remained approximately stable for a period of time (i.e. Stable endemicity). Same as cross-sectional study , converse of longitudinal study. (05 Dec 1998) |

| skeletal survey | A radiographic examination of all or selected parts of the skeleton, as for occult fractures, metastases, etc. (05 Mar 2000) |
| survey | 1. To inspect, or take a view of; to view with attention, as from a high place; to overlook; as, to stand on a hill, and survey the surrounding country. "Round he surveys and well might, where he stood, So high above." (Milton) 2. To view with a scrutinizing eye; to examine. "With such altered looks, . . . All pale and speechless, he surveyed me round." (Dryden) 3. To examine with reference to condition, situation, value, etc.; to examine and ascertain the state of; as, to survey a building in order to determine its value and exposure to loss by fire. 4. To determine the form, extent, position, etc, of, as a tract of land, a coast, harbor, or the like, by means of linear and angular measurments, and the application of the principles of geometry and trigonometry; as, to survey land or a coast. 5. To examine and ascertain, as the boundaries and royalties of a manor, the tenure of the tenants, and the rent and value of the same. Origin: OF. Surveoir, surveer; sur, sor, over, E.

| survey line | A line scribed on an abutment tooth of a dental cast by means of a dental surveyor indicating the height of contour of the tooth according to a specific path of insertion, a line which serves as a guide in the proper location of various parts of a clasp assembly for a removable partial denture. Synonym: clasp guideline, Cummer's guideline. (05 Mar 2000) |
| field survey | The planned collection of data among noninstitutionalised persons in the general population. (05 Mar 2000) |
| biological | Pertaining to biology. (18 Nov 1997) |
| biological agent | <microbiology> A disease-causing microorganism or virus, or other toxic biological matter, which is used as a weapon during war. (21 Mar 1998) |
| biological assay | <technique> Once a pharmaceutical protein is isolated from the cells in which it was grown, researchers perform tests to measure the protein's biological activity. It must maintain a certain minimal level of biological activity to be used for animal or clinical testing or, later, for market. Researchers also test to confirm that the isolated protein is identical to the desired protein. (21 Mar 1998) |
| biological assessment | A specific process required as part of an environmental assessment. An evaluation of potential effects of a proposed project on proposed, endangered, threatened, and sensitive animal and plant species and their habitats. (05 Dec 1998) |
| biological availability | The extent to which the active ingredient of a drug dosage form becomes available at the site of drug action or in a biological medium believed to reflect accessibility to a site of action. (12 Dec 1998) |
| biological chemistry | The scientific study of the chemistry of living cells, tissues, organs and organisms. (09 Oct 1997) |
| biological clock | <biology, physiology> An internal biological mechanism which controls certain biological rhythms and biocycles, such as metabolism, sleep cycles, photosynthesis. (21 Mar 1998) |
| biological clocks | The physiological mechanisms that govern the rhythmic occurrence of certain biochemical, physiological, and behavioural phenomena in plants and animals. The pineal gland, which receives input from the optic nerves and connects to the hypothalamus, may be the biological clock in humans. (12 Dec 1998) |
| biological coefficient | Rarely used term denoting the energy expended by the body at rest. (05 Mar 2000) |
| biological containment | <molecular biology> Refers to any number of methods to contain genetically engineered organisms by creating biochemical barriers to prevent them from growing outside the laboratory. In the case of bacteria and yeasts, genes in the organisms may be altered so that they need to have a supply of a nutrient that is normally found only in the laboratory. (21 Mar 1998) |
