| continuous processing | A method of bioprocessing in which new materials are added and products removed continuously at a rate that maintains the volume at a specific level. (14 Nov 1997) |
|---|---|
| continuous random variable | Continuous variable that may randomly assume any value in its domain but any particular value has no probability of occurring, only a probability density. (05 Mar 2000) |
| continuous spectrum | A spectrum in which there are no absorption bands or lines. (05 Mar 2000) |
| continuous spinal anaesthesia | Insertion of a catheter into the spinal subarachnoid space and leaving it in situ to permit serial intermittent injection of local anaesthetic solution for prolonged spinal anaesthesia. Synonym: fractional spinal anaesthesia. (05 Mar 2000) |
| continuous suture | An uninterrupted series of stitches using one suture; the stitching is fastened at each end by a knot. Synonym: spiral suture, uninterrupted suture. (05 Mar 2000) |
| continuous time model | <epidemiology> A model in which the system changes continuously over time. Derivatives (e.g. DY/dt ) are the mathematical formalism for describing such continuous change. The differential equation which embodies a model provides the values of these derivatives at any particular time point; calculus or a computer can then be used to move the state of the model forwards in time. Continuous models have the advantage over discrete time models in that they are more amenable to algebraic manipulation, although they are slightly harder to implement on a computer. The same as a differential equation model. (05 Dec 1998) |
| continuous tremor | A tremor that is constant, whether the subject is at rest or moving. Synonym: continuous tremor. (05 Mar 2000) |
| continuous variable | A variable that may take on any value in an interval or intervals (its domain). (05 Mar 2000) |
| artificial passive immunity | See: acquired immunity. (05 Mar 2000) |
| passive | Neither spontaneous nor active, not produced by active efforts. Origin: L. Passivus (18 Nov 1997) |
| passive agglutination | Agglutination of particles that have been coated with soluble antigen, by antiserum specific for the adsorbed antigen. Synonym: indirect agglutination. (05 Mar 2000) |
| passive-aggressive behaviour | Apparently compliant behaviour, with intrinsic obstructive or stubborn qualities, to cover deeply felt aggressive feelings that cannot be more directly expressed. (05 Mar 2000) |
| passive-aggressive personality | A personality disorder in which aggressive feelings are manifested in passive ways, especially through mild obstructionism and stubbornness. (05 Mar 2000) |
| passive-aggressive personality disorder | A personality disorder characterised by an indirect resistance to demands for adequate social and occupational performance; anger and opposition to authority and the expectations of others that is expressed covertly by obstructionism, procrastination, stubbornness, dawdling, forgetfulness, and intentional inefficiency. (12 Dec 1998) |
| passive anaphylaxis | A reaction resulting from inoculation of antigen in an animal previously inoculated intravenously with specific antiserum from another animal, a latent period being required between the two inoculations. Synonym: antiserum anaphylaxis. (05 Mar 2000) |
