Dispersion
Definition:
(n.) The act or process of scattering or dispersing, or the state of being scattered or separated; as, the Jews in their dispersion retained their rites and ceremonies; a great dispersion of the human family took place at the building of Babel.
(n.) The separation of light into its different colored rays, arising from their different refrangibilities.
Example Sentences:
(1) The results also suggest that the dispersed condition of pigment in the melanophores represents the "resting state" of the melanophores when they are under no stimulation.
(2) Somatostatin inhibited carbachol- and cholecystokinin octapeptide-induced pepsinogen secretion from dispersed gastric mucosal cells in a dose-dependent manner.
(3) The results of the measurements permitted the identification of five main cytologic types, with regard to nuclear size, nuclear area dispersion and irregularity of nuclear profiles.
