(a.) Especially, emitting or darting rays of light or heat; issuing in beams or rays; beaming with brightness; emitting a vivid light or splendor; as, the radiant sun.
(a.) Beaming with vivacity and happiness; as, a radiant face.
(a.) Giving off rays; -- said of a bearing; as, the sun radiant; a crown radiant.
(a.) Having a raylike appearance, as the large marginal flowers of certain umbelliferous plants; -- said also of the cluster which has such marginal flowers.
(n.) The luminous point or object from which light emanates; also, a body radiating light brightly.
(n.) A straight line proceeding from a given point, or fixed pole, about which it is conceived to revolve.
(n.) The point in the heavens at which the apparent paths of shooting stars meet, when traced backward, or whence they appear to radiate.
Example Sentences:
(1) The thermoregulatory effects of isothermogenic doses of isoproterenol (Iso) and a novel beta-agonist (BRL 35135) were tested in rats at 22 degrees C and in rats trained to bar press for radiant heat at -8 degrees C. BRL 35135 produced hyperthermia at 22 degrees C and reduced operant responding for heat at -8 degrees C, whereas Iso reduced body temperature and increased operant responding.
(2) During five of the treatments skin cooling, by means of initiating air flow through the radiant heating device, was necessary during the plateau phase because rectal temperature exceeded the target value.
(3) It has been found that the UV radiation-induced extreme state of the cells in a radiant culture produces distantly in an intact detector culture, which has only an optic contact with it, the cytopathic effect (CPE) as a repercussion of a specificity of morphological manifestations imprinted in the affected culture.
(4) Extracellular activity of single WDR neurons in the spinal dorsal horn, which was evoked by a radiant heat stimulus (51 degrees C), was recorded in decerebrate, spinally transected cats.
