| neutralization | 1. The act or process of neutralising, or the state of being neutralized. 2. <chemistry> The act or process by which an acid and a base are combined in such proportions that the resulting compound is neutral. See Neutral. Origin: Cf. F. Neutralisation. Source: Websters Dictionary (01 Mar 1998) |

| neutralization plate | A metal plate used for the internal fixation of a long bone fracture to neutralise the forces producing displacement. (05 Mar 2000) |
| neutralization test | A test to determine the antimicrobial activity of a serum by inoculating a susceptible animal with a mixture of the serum and the virus or other microbe being tested. Synonym: neutralization test. (05 Mar 2000) |
| neutralization tests | Titration of an antiserum by testing a series of dilutions of virus or immune serum to a given end-point, which is generally the dilution at which tissue cultures inoculated with the serum-virus mixtures demonstrate cytopathology (cpe) or the dilution at which 50% of test animals injected with serum-virus mixtures show infectivity (id50) or die (ld50). (12 Dec 1998) |
| fractional | 1. Of or pertaining to fractions or a fraction; constituting a fraction; as, fractional numbers. 2. Relatively small; inconsiderable; insignificant; as, a fractional part of the population. <chemistry> Fractional crystallization, a process of distillation so conducted that a mixture of liquids, differing considerably from each other in their boiling points, can be separated into its constituents. Source: Websters Dictionary (01 Mar 1998) |
| fractional condensation | A lab technique used to separate the components of a vapor containing a mixture of substances. This is done by taking advantage of the fact that the different chemicals have different boiling points. The mixture undergoes repeated condensations, where the chemical with the highest boiling point condenses out of the vapor first and can be separated from the rest, then the chemical with the next highest boiling point condenses out, etc. (09 Oct 1997) |
| fractional distillation | Distillation of a compound liquid at varying degrees of heat whereby the components of different boiling points are collected separately. (05 Mar 2000) |
| fractional dose | A definite fraction of a full dose; given repeatedly at short intervals so that the full dose is taken within a specified period, usually one day. Synonym: fractional dose. (05 Mar 2000) |
| fractional epidural anaesthesia | Insertion of a catheter into the lumbar or caudal epidural space for the repeated injection of local anaesthetic solutions as a means of prolonging duration of anaesthesia. Synonym: fractional epidural anaesthesia. (05 Mar 2000) |
| fractional 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) |
| fractional sterilization | Exposure to a temperature of 100°C (flowing steam) for a definite period, usually an hour, on each of several days; at each heating the developed bacteria are destroyed; spores, which are unaffected, germinate during the intervening periods and are subsequently destroyed. Synonym: discontinuous sterilization, intermittent sterilization, tyndallization. (05 Mar 2000) |
