| ergodic | <radiobiology> A mathematical term meaning space-filling. If a magnetic field is ergodic, any field line will eventually pass arbitrarily close to any point in space. Closely related to chaotic. (09 Oct 1997) |
|---|---|
| ergodic regime | <radiobiology> In this regime, a given magnetic field line will cover every single point on a magnetic surface (see magnetic surface or flux surface) if the rotational transform (or q) is not rational. (09 Oct 1997) |
| ergodynamograph | An instrument for recording both the degree of muscular force and the amount of the work accomplished by muscular contraction. Origin: ergo-+ G. Dynamis, force, + grapho, to write (05 Mar 2000) |
| ergoesthesiograph | An apparatus for recording graphically muscular aptness as shown in the ability to counterbalance variable resistances. Origin: ergo-+ G. Aisthesis, sensation, + grapho, to record (05 Mar 2000) |
| ergogenic | Tending to increase work. (05 Mar 2000) |
| ergograph | An instrument for recording the amount of work done by muscular contractions, or the amplitude of contraction. Origin: ergo-+ G. Grapho, to write Mosso's ergograph, an instrument consisting of pulleys, weights, and a recording lever, which is used to obtain a graphic record of flexion of a finger, hand, or arm. (05 Mar 2000) |
| ergographic | Relating to the ergograph and the record made by it. (05 Mar 2000) |
| ergolines | A class of drugs with prominent agonistic or antagonistic actions on dopamine receptors. Agents belonging to this group include bromocriptine, pergolide, and lisuride. (05 Mar 2000) |
| ergoloid mesylates | <chemical> Dihydroergotoxine monomethanesulfonate. A mixture of the mesylates of dihydroergocornine, dihydroergocristine, and the alpha- and beta-isomers of dihydroergocryptine. The substance produces a generalised peripheral vasodilation and a fall in arterial pressure and has been used to treat symptoms of mild to moderate impairment of mental function in the elderly. Pharmacological action: adrenergic alpha-antagonists, nootropic agents, vasodilator agents. Chemical name: Ergotoxine, dihydro-, monomethanesulfonate (salt) (12 Dec 1998) |
| ergometer | Synonym: dynamometer. Origin: ergo-+ G. Metron, measure (05 Mar 2000) |
| ergometrine | Synonym: ergonovine. (05 Mar 2000) |
| ergometrine maleate | ergonovine maleate |
| ergometry | Any method of measuring the amount of work done by an organism, usually during exertion. Ergometry also includes measures of power. Some instruments used in these determinations include the hand crank and the bicycle ergometer. (12 Dec 1998) |
| ergon | <unit> A unit used to measure or represent the stability of a gene over the lifetime of a given organism. It is a function of the ratio of the adenine-thymine to the guanine-cytosine content of the gene, and is evidenced by the continual physical expression of the trait coded by the gene. (11 Nov 1997) |
| ergonomics | A branch of ecology concerned with human factors in the design and operations of machines and the physical environment. Origin: ergo-+ G. Nomos, law (05 Mar 2000) |
