| 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) |
| 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). (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) |
| adrenal mass | <radiology> Metastasis, most common (especially lung, melanoma), primary adenocarcinoma, large at diagnosis (greater than 5 cm), usually functional (increased corticosteroids most likely to be Cushing's), rapid growth, benign adrenal adenoma, with or without functional, nonfunctional occurs in 2-8% of population, diff from metastasis: MRI (metastasis bright on T2), biopsy, follow, pheochromocytoma, neuroblastoma, myelolipoma, cyst / pseudocyst see also: adrenal calcification, haemorrhage (12 Dec 1998) |
| apperceptive mass | The already existing knowledge base in a similar or related area with which the new perceptual material is articulated. (05 Mar 2000) |
| atomic mass | <chemistry, physics> The mass of an atom relative to other atoms. The present-day basis of the scale of atomic weights is carbon, the most common isotope of this element has arbitrarily been assigned an atomic weight of 12. The unit of the scale is 1/12 the weight of the carbon atom or roughly the mass of one proton or one neutron. The atomic weight of any element is approximately equal to the total number of protons and neutrons in is nucleus (16 Dec 1997) |
| atomic mass unit | <chemistry> One-twelfth the mass of a neutral atom of the most abundant isotope of carbon. (16 Dec 1997) |
| bilateral adrenal mass | <radiology> Acute granulomatous disease (e.g., TB), metastases (bilateral in 15%), pheochromocytoma (bilateral in 10%), adrenal hyperplasia (adenoma), spontaneous adrenal haemorrhage (12 Dec 1998) |
| body mass index | One of the anthropometric measures of body mass; it has the highest correlation with skinfold thickness or body density. (12 Dec 1998) |
