| Fick's laws of diffusion | The direction of movement of solutes by diffusion is always from a higher to a lower concentration and the diffusive flux JA of solute A across a plane at x is proportional to the concentration gradient of A at x; i.e., JA = -D(CA/x), the increase of concentration of solute A with time, CA/t, is directly proportional to the change in the concentration gradient, i.e., CA/t = D(fl2/x2).

| Fick method | In 1870 A. Fisk proposed that cardiac output can be calculated as the quotient of total body oxygen consumption divided by the difference in oxygen content of arterial blood and mixed venous blood. In the direct Fick method all variables are measured. The indirect Fick method employs a variety of means to avoid measuring mixed venous oxygen content. By extension, the Fick method may be used to measure cardiac output or organ blood flow with any indicator substance for which the rate of uptake or consumption, and the arterial and mixed venous concentrations, can be measured, provided the indicator does not enter or leave the system by any route not being measured. Synonym: Fick principle. (05 Mar 2000) |

| Ambard's laws | <physiology> Obsolete law's for output of urea: 1. With the urinary urea concentration constant, urea output varies directly as the square of the concentration of the blood urea. 2. With the blood urea concentration constant, urea output varies inversely as the square root of its urinary concentration. (05 Mar 2000) |
| antitrust laws | Those federal and state laws, and their enforcement, that protect trade and commerce from unlawful restraints and monopolies or unfair business practices. (12 Dec 1998) |
| Mendel's laws | <genetics> The two basic principles of genetics proposed by Gregor Mendel. The law of segregation, which states that the alleles governing a trait are separated during the creation of gametes (meiosis). The law of independent assortment, which states that the genes controlling different traits are distributed separately from each other during meiosis. (13 Nov 1997) |
| Rubner's laws of growth | The law of constant energy consumption: the rapidity of growth is proportional to the intensity of the metabolic processes, the law of the constant growth quotient: in most young mammals, 24% of the entire food energy, or calories, is utilised for growth; in humans only 5% is utilised. (05 Mar 2000) |
| scaling laws | <radiobiology> These are mathematical rules explaining how variation in one quantity affects variations in other quantities. For instance, in a tokamak reactor its generally believed that energy confinement depends on the size of the device and the strength of the magnetic field, but the precise nature of the dependence is not fully understood, so empirical scaling laws are tested to see what the dependence is. Scaling laws are useful for extrapolating from parameter regimes where the mathematical relationships between the various quantities are known, into unexplored regimes. (09 Oct 1997) |
| Thoma's laws | The development of blood vessels is governed by dynamic forces acting on their walls as follows: an increase in velocity of blood flow causes dilation of the lumen; an increase in lateral pressure on the vessel wall causes it to thicken; an increase in end-pressure causes the formation of new capillaries. (05 Mar 2000) |
| Faraday's laws | The amount of an electrolyte decomposed by an electric current is proportional to the amount of the current, when the same current is passed through several electrolytes, the amounts of the different substances decomposed are proportional to their chemical equivalents. (05 Mar 2000) |
| laws of association | Principles formulated by Aristotle to account for the functional relationships between ideas; the law of contiguity (association) proved most useful to experimental psychologists, culminating in modern studies of respondent conditioning. (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) |
