| ratio | 1. <mathematics> The relation which one quantity or magnitude has to another of the same kind. It is expressed by the quotient of the division of the first by the second; thus, the ratio of 3 to 6 is expressed by 3/6/ or 1/2; of a to b by a/b; or (less commonly) the second is made the dividend; as, a:b = b/a. Some writers consider ratio as the quotient itself, making ratio equivalent to a number. The term ratio is also sometimes applied to the difference of two quantities as well as to their quotient, in which case the former is called arithmetical ratio, the latter, geometrical ratio. The name ratio is sometimes given to the rule of three in arithmetic. See Rule. 2. Hence, fixed relation of number, quantity, or degree; rate; proportion; as, the ratio of representation in Congress. Compound ratio, Duplicate ratio, Inverse ratio, etc. See Compound, Duplicate, etc. Ratio of a geometrical progression, the constant quantity by which each term is multiplied to produce the succeeding one. Origin: L, fr. Reri, ratus, to reckon, believe, think, judge. See Reason. Source: Websters Dictionary (01 Mar 1998) |

| ratio imaging fluorescence microscopy | <procedure> A method of measurement of intracellular pH or intracellular calcium levels, using a fluorescent probe molecule (see fura-2), in which the two different excitation wavelengths are used and the emitted light levels compared. If emission at one wavelength is sensitive to the intracellular ion level and emission at the other wavelength is not, then standardisation for intracellular probe concentration, efficiency of light collection, inactivation of probe and thickness of cytoplasm can all be performed automatically.

| ration | 1. A fixed daily allowance of provisions assigned to a soldier in the army, or a sailor in the navy, for his subsistence. Officers have several rations, the number varying according to their rank or the number of their attendants. 2. Hence, a certain portion or fixed amount dealt out; an allowance; an allotment.

| rational | 1. Relating to reason; not physical; mental. "Moral philosophy was his chiefest end; for the rational, the natural, and mathematics . . . Were but simple pastimes in comparison of the other." (Sir T. North) 2. Having reason, or the faculty of reasoning; endowed with reason or understanding; reasoning. "It is our glory and happiness to have a rational nature." (Law) 3. Agreeable to reason; not absurd, preposterous, extravagant, foolish, fanciful, or the like; wise; judicious; as, rational conduct; a rational man. 4. <chemistry> Expressing the type, structure, relations, and reactions of a compound; graphic; said of formulae. See Formula. Rational horizon. <astronomy> See Horizon, 2 . <mathematics> Rational quantity, one elicited by the statements of the patient himself and not as the result of a physical examination. Synonym: Sane, sound, intelligent, reasonable, sensible, wise, discreet, judicious. Rational, reasonable. Rational has reference to reason as a faculty of the mind, and is opposed to traditional; as, a rational being, a rational state of mind, rational views, etc. In these cases the speculative reason is more particularly, referred to. Reasonable has reference to the exercise of this faculty for practical purposes, and means, governed or directed by reason; as, reasonable prospect of success.

| rational surface | <physics> Magnetic flux surface where the ratio of toroidal to poloidal field strengths is a rational number, this means that a particle travelling along this surface makes an integer number of turns in each direction and then its orbit closes in on itself. The result is that the particle does not sample the entire flux surface in its motion, which is important for various technical reasons (which mostly result in reduced confinement). See: magnetic island. (09 Oct 1997) |
