| convalescence | The stage of recovery following an attack of disease, a surgical operation or an injury. Origin: L. Convalescere = to become strong (18 Nov 1997) |
|---|---|
| convalescent | 1. Getting well or one who is getting well. 2. Denoting the period of convalescence. (05 Mar 2000) |
| convalescent carrier | An individual who is clinically recovered from an infectious disease but is still capable of transmitting the infectious agent to others. (05 Mar 2000) |
| convalescent serum | Serum from patients recently recovered from a disease; useful in preventing or modifying by passive immunization the same disease in exposed susceptible individuals. (05 Mar 2000) |
| convallaria | The flower, rhizome, and roots of Convallaria majalis (family Liliaceae), lily of the valley; they contain glycosides with digitalis-like action (e.g., convallatoxin). Origin: L. Convallis, an enclosed valley (05 Mar 2000) |
| convection | Transmission of energy or mass by a medium involving movement of the medium itself. The circulatory movement that occurs in a fluid at a nonuniform temperature owing to the variation of its density and the action of gravity. (12 Dec 1998) |
| convective heat | Heat conveyed by a warm medium, such as air or water, in motion from its source. (05 Mar 2000) |
| convenience form | The changes needed outside the basic outline form to enable proper instrumentation for the cavity preparation and insertion of a dental restoration. (05 Mar 2000) |
| conventional | Following what is traditional or customary. (18 Nov 1997) |
| conventional animal | An animal colonised by the burden of resident microorganisms normally associated with its particular species. (05 Mar 2000) |
| conventional forest products | Any commercial roundwood product (boards, dimension lumber, pulp and paper products) except fuelwood. (05 Dec 1998) |
| conventional signs | Sign's that acquire their function through social (linguistic) custom; e.g., words, mathematical symbols. See: symbol. (05 Mar 2000) |
| conventional tomography | <procedure, radiology> The recording of internal body images at a predetermined plane by means of the tomograph, also called body section roentgenography. Origin: Gr. Graphein = to write (18 Nov 1997) |
| Conventional Transmission Electron Microscopy | <technique> A term applied to 'normal' transmission electron microscopy imaging. The electron beam is passed through a thin film sample (typically ~1-200 nm thick). Bright field diffraction contrast images are formed with the direct (undiffracted) beam. Dark field images are formed with a selected diffracted beam. CTEM imaging is used in the general observation of samples and careful selection of the diffracting conditions of the sample will allow the analysis of defect structures within the sample. (05 Aug 1998) |
| convergence | <microscopy> In colour video cameras and monitors, the precise alignment of the images or pictures in the three primary colours (red, green and blue). A lack of convergence gives rise to asymmetrically coloured fringes. (05 Aug 1998) |
