|---|---|
| tritium | <physics, radiobiology> Long lived radioactive isotope of hydrogen (half life 12.26 years). Weak emitter, very suitable for autoradiography and relatively easy to incorporate into complex molecules. (18 Nov 1997) |
| tritium inventory | <radiobiology> Total quantity of tritium stored in a facility. Minimising this radioactive inventory is a key reactor design issue. (09 Oct 1997) |
| tritium-breeding ratio | <radiobiology> The amount of tritium generated by the breeding blanket of a D-T fusion reactor, divided by the amount of tritium burned in the reactor. A tritium breeding ration greater than unity is necessary for self-sufficient fueling. (09 Oct 1997) |
| tritocaline | 7-amino-4,5,6-triethoxy-3-(5,6,7,8-tetrahydro-4-methoxy-6-methyl-1,3-dioxolo[4,5-g]isoquinolin-5-yl)phthalide;an antihistaminic. Synonym: tritocaline. (05 Mar 2000) |
| tritolyl phosphates | Phosphoric acid tri(methylphenyl) ester. A mixture of isomeric tritolyl phosphates. Used in the sterilization of certain surgical instruments and in many industrial processes. (12 Dec 1998) |
| triton | <radiobiology> The nucleus of a tritium atom, tritium ion. See: tritium. (09 Oct 1997) |
| triton burnup | <radiobiology> Tritons produced in fusion reactions may fuse with other plasma particles as they slow down, thus burning up and (for D-T burnup reactions in a D-D plasma) emitting 14.7 MeV neutrons which can be measured, distinct from other sources. Measurements of the burnup of tritons (predominantly formed in the hot core of the plasma) can provide a test of particle transport in the plasma. (09 Oct 1997) |
| triton tumour | A peripheral nerve tumour with striated muscle differentiation, seen most often in neurofibromatosis; named after Masson's theory of transformation of motor nerve fibres into muscle in triton salamanders. (05 Mar 2000) |
| Triton X 100 | <chemical> Nonionic detergent used in isolating membrane proteins: the detergent replaces the phospholipids that normally surround such a protein. Other detergents of the Triton group are occasionally used so the full name should be quoted. (18 Nov 1997) |
| tritoqualine | 7-amino-4,5,6-triethoxy-3-(5,6,7,8-tetrahydro-4-methoxy-6-methyl-1,3-dioxolo[4,5-g]isoquinolin-5-yl)phthalide;an antihistaminic. Synonym: tritocaline. (05 Mar 2000) |
| tritovum | <zoology> An embryonic insect which has twice cast its skin previous to hatching from the egg. Origin: NL, fr. Gr. Third + L. Ovum egg. Source: Websters Dictionary (01 Mar 1998) |
| tritozooid | <zoology> A zooid of the third generation in asexual reproduction. Origin: Gr. Third + an animal. Source: Websters Dictionary (01 Mar 1998) |
| tritrichomonas | A genus of flagellate protozoans possessing three long anterior flagella. (12 Dec 1998) |
| tritrichomonas foetus | A species of flagellate parasitic protozoa. It possesses a long undulating membrane that is bordered on its outer margin by a flagellum that becomes free posteriorly. This organism causes infections in cows that could lead to temporary infertility or abortion. (12 Dec 1998) |
