| thermonuclear fusion | <radiobiology> Fusion achieved by heating the fuel into the plasma state to the point where ions have sufficient energy to fuse. Also used to characterise fusion between thermal ions as opposed to fusion involving injected beam ions. (09 Oct 1997) |
|---|
| controlled thermonuclear fusion | <radiobiology> The process in which light nuclei, heated to a high temperature in a confined region, undergo fusion reactions under controlled conditions, with associated release of energy which may be harnessed for useful purposes. (09 Oct 1997) |
|---|---|
| controlled thermonuclear research | General label for research on controlled thermonuclear fusion reactions. (09 Oct 1997) |
| thermonuclear | Pertaining to nuclear reactions brought about by nuclear fusion; (e.g., the fusion of hydrogen to helium at temperatures of over 100,000,000°C). (the reaction in the "hydrogen bomb"). (05 Mar 2000) |
| thermonuclear conditions | <radiobiology> Achievement of an adequately confined plasma, having temperature and density sufficiently high to yield significant release of energy from fusion reactions. (09 Oct 1997) |
| thermonuclear reaction | <radiobiology> See thermonuclear fusion, above. (09 Oct 1997) |
| zero energy thermonuclear assembly | <radiobiology> A British fusion device in which scientists observed fusion neutrons in 1958. They were erroneously considered to be thermonuclear (coming from particles with a Maxwellian velocity distribution) and were a cause for the initial optimism that fusion energy would be easy. They were actually due to electromagnetic acceleration during a plasma instability, an effect which cannot be scaled up to produce useful energy. (09 Oct 1997) |
| atrial fusion beat | A beat that occurs when the atria are activated in part by the sinus impulse and in part by an ectopic or retrograde impulse from A-V junction or ventricle. (05 Mar 2000) |
| magnetic confinement fusion | <physics> Method of fusion which uses magnetic fields / magnetic bottles to confine a hot plasma until fusion occurs. (09 Oct 1997) |
| gene fusion | Fusion of structural genes to analyze protein behaviour or fusion of regulatory sequences with structural genes to determine mechanisms of regulation. (12 Dec 1998) |
| ventricular fusion beat | A fusion beat that occurs when the ventricles are activated partly by the descending sinus or A-V junctional impulse and partly by an ectopic ventricular impulse. (05 Mar 2000) |
| recombinant fusion proteins | Proteins that are the result of genetic engineering. A regulatory part or promoter of one or more genes is combined with a structural gene. The fusion protein is formed after transcription and translation of the fused gene. This type of fusion protein is used in the study of gene regulation or structure-activity relationships. They might also be used clinically as targeted toxins (immunotoxins). (12 Dec 1998) |
| vertebral fusion | A procedure that involves fusing together two or more vertebrae in the spine using either bone grafts or metal rods (Harrington rods). This procedure may be used to correct kyphosis or scoliosis. It is also used in those who require spine stabilisation due to vertebral damage from ruptures discs, fractures, osteomyelitis, osteoarthritis or tumour. (27 Sep 1997) |
| viral fusion proteins | Proteins, usually glycoproteins, found in the viral envelopes of a variety of viruses. They promote cell membrane fusion and thereby may function in the uptake of the virus by cells. (12 Dec 1998) |
| cell fusion | <biology, embryology> Fusion of two previously separate cells occurs naturally in fertilization and in the formation of vertebrate skeletal muscle, but can be induced artificially by the use of Sendai virus or fusogens such as polyethylene glycol. Fusion may be restricted to cytoplasm or nuclei may fuse as well. A cell formed by the fusion of dissimilar cells is often referred to as a heterokaryon. (26 Mar 1998) |
| centric fusion | <molecular biology> A special type of nonreciprocal translocation in chromosomes whereby the long arms of two nonhomologous acrocentric chromosomes are attached to a single centromere. The short arms become attached to form a reciprocal structure that however often disappears some divisions after its formation. (17 Dec 1997) |
