| strain fracture | The tearing off, by a sudden force, of a piece of bone attached to a tendon, ligament, or capsule; the force may be exogenous or endogenous. (05 Mar 2000) |
|---|---|
| strain gauge | A device, employing the Wheatstone bridge principle, used for accurate measurement of forces such as strain, stress, or pressure. (05 Mar 2000) |
| stress-strain curve | A curve showing the ratio of deformation to load during the testing of a material in tension. (05 Mar 2000) |
| inbred strain | Any strain of animal or plant obtained by a breeding strategy that tends to lead to homozygosity. Such breeding strategies include brother sister mating and back crossing of offspring with parents. See: congenic. (18 Nov 1997) |
| isogenic strain | A strain of animals inbred for many generations and with high probability homozygous for certain specified genes. (05 Mar 2000) |
| type strain | The nomenclatural type of a species or subspecies. (05 Mar 2000) |
| Flury strain rabies virus | <organism, virology> Species of the Rhabdoviridae that causes rabies in humans. The virus infects the cells in the brain, causing a fatal encephalomyelitis. It is found all over the world, but strict quarantine regulations have excluded it from Britain and Australia. The virus infects a number of domestic and wild mammals, whose saliva is infective. Some bats and small mammals can carry the virus without showing any symptoms of disease. (18 Nov 1997) |
| Flury strain vaccine | An inactivated virus vaccine, used for preexposure immunization to persons at high risk of exposure, e.g., veterinarians, and in conjunction with rabies immunoglobulin, for postexposure prophylaxis. The official preparation is human diploid cell vaccine produced from rabies virus grown in cultures of human diploid embryo lung cells and inactivated with propriolactone. It has a much lower incidence of adverse reactions than the previously used duck embryo vaccine. (12 Dec 1998) |
| lysogenic strain | A strain of bacterium that is infected with a temporate bacteriophage. See: lysogeny. (05 Mar 2000) |
| activation energy | <chemistry> The amount of energy (expressed in joules) that is needed to convert all the molecules in one mole of a reacting substance from a ground state to the transition state. (06 May 1997) |
| binding energy | <chemistry, radiobiology> The binding energy of a nucleus is the minimum energy required to dissociate it into its component neutrons and protons. Neutron or proton binding energies are those required to remove a neutron or proton, respectively, from a nucleus. Electron binding energy is that required to remove an electron from an atom or a molecule. (16 Dec 1997) |
| bioelectric energy sources | Implantable devices which convert biological energy (chemical energy of the metabolism of continuously regenerating body fluids or mechanical energy of periodic movements) to electrical energy. The sources include biogalvanic cells, biofuel cells, and ionic concentration cells. (12 Dec 1998) |
| biomass energy | See Bioenergy. (05 Dec 1998) |
| bond dissociation energy | This is the energy needed to break the bonds between two linked atoms. (09 Oct 1997) |
| bond energy | The energy needed to break a molecular bond. (09 Oct 1997) |
