| continuity | Absence of interruption, a succession of parts intimately united, e.g., the unbroken conjunction of cells and structures that make up a single bone of the skull. Compare: contiguity. Origin: L. Continuus, continued (05 Mar 2000) |
|---|---|
| continuity of patient care | Health care provided on a continuing basis from the initial contact with a physician or clinic and following the patient through all episodes of his medical care needs. (12 Dec 1998) |
| Haldane's evolutionary unit | <unit> A unit of measurement, given in darwins, which measures the increase in body size of a chronospecies over evolutionary time. (13 Nov 1997) |
| solution of continuity | Division of bones or soft parts that are normally continuous, as by a fracture, a laceration, or an incision. Synonym: dieresis. (05 Mar 2000) |
| synthesis of continuity | Healing of the edges of a wound or fracture. (05 Mar 2000) |
| evolutionary computation | <genetics> Evolutionary computation, genetic algorithms, and genetic programming are all computer disciplines involved with modeling genetic inheritance and/or biological evolution in computers. (09 Oct 1997) |
| evolutionary distance | <botany> In phylogenetic trees, the sum of the physical distance on a tree separating organisms, this distance is inversely proportional to evolutionary relatedness. (09 Oct 1997) |
| evolutionary fitness | The probability that the line of descent from an individual with a specific trait will not eventually die out. (05 Mar 2000) |
| active principle | A constituent of a drug, usually an alkaloid or glycoside, upon the presence of which the characteristic therapeutic action of the substance largely depends. (05 Mar 2000) |
| antianaemic principle | The material in liver (and certain other tissues) that stimulates haemopoiesis in pernicious anaemia; for practical purposes, the antianaemic effect of extracts from such tissues is approximately equivalent to the content of vitamin B12. (05 Mar 2000) |
| azygos vein principle | A principle based on the observation that animals can survive prolonged vena caval occlusion without sequelae: if blood from the azygos vein alone is permitted to enter the heart, patients are perfused during cardiac and pulmonary bypass at flows much less than the normal resting cardiac output. Synonym: low flow principle. (05 Mar 2000) |
| Bernoulli's principle | <physics> When friction is negligible, the velocity of flow of a gas or fluid through a tube is inversely related to its pressure against the side of the tube; i.e., velocity is greatest and pressure lowest at a point of constriction. Synonym: Bernoulli's principle, Bernoulli's theorem. (05 Mar 2000) |
| pain-pleasure principle | A psychoanalytic concept that, in a human's psychic functioning, he/she tends to seek pleasure and avoid pain; a term borrowed by experimental psychology to denote the same tendency of an animal in a learning situation. Synonym: pleasure principle. (05 Mar 2000) |
| reality principle | The concept that the pleasure principle in personality development is modified by the demands of external reality; the principle or force that compels the growing child to adapt to the demands of external reality. (05 Mar 2000) |
| Pauli's exclusion principle | The theory limiting the number of electrons in the orbit or shell of an atom; that it is not possible for any two electrons to have all four quantum numbers identical. (05 Mar 2000) |
