(1) These results suggest that histamine reduces the reflection coefficient for protein at the capillary wall and are consistent with predictions of the theory of restricted diffusion assuming that 1-2.5% of available pores increase in radious from 40 to 240 A.
(2) Ogston's (1958) fiber model based on Poisson's distribution function gives the average number of fibers making contact and no contact inside a sphere of radius r. The probability of penetration of spherical particles within a fibrous network was derived from the moment generating function [Formula: see text] A is the number of particles that intrude into a sphere of radious r. alpha(mu) is the probability that a particle, whose center is mu units away from the origin, intrudes into a sphere of radius r. A has a Poisson distribution with a mean value E(A) = 4pinualpha(mu)mu(2)dmu.
Radius
Definition:
(n.) A right line drawn or extending from the center of a circle to the periphery; the semidiameter of a circle or sphere.
(n.) The preaxial bone of the forearm, or brachium, corresponding to the tibia of the hind limb. See Illust. of Artiodactyla.
(n.) A ray, or outer floret, of the capitulum of such plants as the sunflower and the daisy. See Ray, 2.
(n.) The barbs of a perfect feather.
(n.) Radiating organs, or color-markings, of the radiates.
(n.) The movable limb of a sextant or other angular instrument.
Example Sentences:
(1) The mobility on sodium dodecyl sulfate-polyacrylamide gel electrophoresis is anomalous since the undenatured, cross-linked proteins have the same Stokes radius as the native, uncross-linked alpha beta gamma heterotrimer.
(2) The radius is estimated to be around 1.7 nm, which shows a moderate degree of hydration.
(3) Eight cases of calcification following anterior dislocation of the head of the radius are described.
(4) Conservatively treated compressed fractures of the distal radius dorsal metaphysis healed despite primarily good reduction and consequent treatment with a decrease in dorsal length.
(5) Modifications in quaternary structure induced by variation of these physicochemical parameters were followed by means of X-ray and quasi-elastic light-scattering and quantified in terms of weight average molecular weight (M), radius of gyration (Rg) and hydrodynamic radius (Rh).
(6) From the different shapes of the scattering curves of the native phosphofructokinase at pH 7.5 in the presence of 15 mM ATP and of the cross-linked tetramer or octamer, it can be inferred that the shapes of the protomers are different: in the presence of ATP the protomers are elongated, having an axial ratio of 1.8 to 2.0; the cross-linked state reveals a spherical protomer of radius 33.0 A, similar to that of the native enzyme at pH 7.5 in the presence of fructose 6-phosphate or fructose 1,6-bisphosphate.
(7) The radius of curvature was shorter in the former than in the latter.
(8) Fluid flow increased approximately 50% for each gauge catheter when the height was raised from 0.91 to 1.75 m. Flow rates increased linearly with increasing catheter radius.
(9) The effect of increasing acetylcholine concentration can best be explained by postulating an increase in the effective channel radius of the water secretion pathway from 0.40 nm to 0.45 nm together with a small increase in the fraction of the total water flow passing through larger non-selective pores.
(10) Recently recovered hominid postcrania from Member 1, Swartkrans Formation include the proximal and distal ends of a right radius attributed to a single individual of Paranthropus robustus.
