| two-parted | <biology> Divided from the border to the base into two distinct parts; bipartite. <botany> Divided from the border to the base into two distinct parts; bipartite. Source: Websters Dictionary (01 Mar 1998) |

| two-ranked | <botany> Alternately disposed on exactly opposite sides of the stem so as to from two ranks; distichous. Source: Websters Dictionary (01 Mar 1998) |
| two-sided | 1. Having two sides only; hence, double-faced; hypocritical. 2. <biology> Symmetrical. Source: Websters Dictionary (01 Mar 1998) |
| two-step exercise test | A test used mainly for coronary insufficiency; significant depression of RS-T in the electrocardiogram is considered abnormal and suggests coronary insufficiency. (05 Mar 2000) |
| two-step procedure | <surgery> When surgical biopsy and breast surgery are performed in two separate surgeries. (09 Oct 1997) |
| two-stream amplifier | <radiobiology> Microwave amplifier based on the two-stream instability. (09 Oct 1997) |
| two-stream instability | <radiobiology> Instability which can develop when a stream of particles of one type has a velocity distribution with its peak well separated from that of another type of particle through which it is flowing. A stream of energetic electrons passing through a cold plasma can, for example: excite ion waves which will grow rapidly in magnitude at the expense of the kinetic energy of the electrons. (09 Oct 1997) |
| two-sympathin theory | A theory, now obsolete, advanced by Cannon and Rosenblueth that two different types of substances (sympathin E and I) diffuse into circulation when adrenergic nerves are stimulated, although the mediator itself is the same. (05 Mar 2000) |
| two-tail test | A statistical test based on the assumption that the data are distributed in both directions from some central value. (05 Mar 2000) |
| two-way catheter | A catheter with two lumens, allowing irrigation and aspiration. Synonym: two-way catheter. (05 Mar 2000) |
| ambipolar diffusion | <radiobiology> Diffusion process in which buildup of spatial charge creates electric fields which cause electrons and ions to leave the plasma at the same rate. (Such electric fields are self-generated by the plasma and act to preserve charge neutrality.) (09 Oct 1997) |
| anomalous diffusion | <radiobiology> Diffusion in most plasma devices, particularly tokamaks, is higher than what one would predict from understood causes. The observed, typical diffusion is referred to as anomalous because it has not yet been explained. Anomalous diffusion includes all diffusion which is not due to collisions and geometric effects. While such effects were not understood when the term was coined, and most still are not, diffusion due to well-understood wave phenomena is still 'anomalous'. Classical diffusion and Neo-classical diffusion are the two well-understood diffusion theories, although neither is adequate to fully explain the observed anomalous diffusion. See: entries for classical diffusion and neoclassical diffusion. Anomalous resistivity (09 Oct 1997) |
| bohm diffusion | <radiobiology> A rapid loss of plasma across magnetic field lines caused by microinstabilities. Theory formulated by the physicist David Bohm. Semiempirical formula for the diffusion coefficient given by Bohm in 1946 (noted by Bohm, Burhop, and Massey, who were developing a magnetic arc for use in uranium isotope separation). Bohm diffusion was proposed (not derived from first principles) to scale as 1/B rather than the 1/B^2 scaling predicted by classical diffusion. A 1/B scaling results from assuming that particles diffuse across field lines at an optimum rate (effective collision frequency=cyclotron frequency). The 1/B scaling is observed (approximately) in most reactors. See: diffusion, microinstabilities, field lines. (09 Oct 1997) |
| passive diffusion | See: facilitated transport. (05 Mar 2000) |
| classical diffusion | <radiobiology> In plasma physics, diffusion due solely to scattering (collisions) of charged particles (with unlike charges) via electrical (Coulomb) interactions. (See also diffusion.) (09 Oct 1997) |
