| van der Waals attraction | <chemistry> Electrodynamic forces arise between atoms, molecules and assemblies of molecules due to their vibrations giving rise to electromagnetic interactions, these are attractive when the vibrational frequencies and absorptions are identical or similar, repulsive when nonidentical. Other interactions originally proposed by van der Waals were included in this name, but these are usually separated into the Coulomb's force, the Keesom force and the London force. Only the last is of electrodynamic nature. Probably important in holding lipid membranes into that structure and possibly in other interactions, for example cell adhesion. Electrodynamic forces between large scale assemblies can be of relatively long range nature. (18 Nov 1997) |
| van der Waals' forces | First postulated by van der Waals in 1873 to explain deviations from ideal gas behaviour seen in real gases; the attractive force's between atoms or molecules other than electrostatic (ionic), covalent (sharing of electrons), or hydrogen bonding (sharing a proton); generally ascribed to dipolar and dispersion effects, π-electrons, etc.; these relatively nondescript force's contribute to the mutual attraction of organic molecules. Synonym: London forces. (05 Mar 2000) |

| van't Hoff's law | In stereochemistry, all optically active substances have one or more multivalent atoms united to four different atoms or radicals so as to form in space an unsymmetrical arrangement, the osmotic pressure exerted by any substance in very dilute solution is the same that it would exert if present as gas in the same volume as that of the solution; or, at constant temperature, the osmotic pressure of dilute solutions is proportional to the concentration (number of molecules) of the dissolved substance; i.e., the osmotic pressure, π, in dilute solutions is π = RTσci, where R is the universal gas constant, T is the absolute temperature, and ci is the molar concentration of solute i, the rate of chemical reactions increases between two-and three-fold for each 10°C rise in temperature.

| Canavan-van Bogaert-Bertrand disease | Autosomal recessive degenerative disease of infancy; mostly in Jewish infants; onset typically within first 3-4 months of birth, consisting of blindness, psychomotor regression, enlarged head, optic atrophy, hypotonia, spasticity, increased N-acetylaspartic acid urinary excretion. MRI shows enlarged brain, decreased attenuation of cerebral and cerebellar white matter, and normal ventricles. Pathologically, there is increased brain volume and weight, and spongy degeneration in the subcortical white matter. See: leukodystrophy. Synonym: Canavan's sclerosis, Canavan-van Bogaert-Bertrand disease, spongy degeneration of infancy. (05 Mar 2000) |
| van | The front of an army; the first line or leading column; also, the front line or foremost division of a fleet, either in sailing or in battle. "Standards and gonfalons, twixt van and rear, Stream in the air." (Milton) Origin: Abbrev. Fr. Vanguard. 1. A fan or other contrivance, as a sieve, for winnowing grain. 2. [OF. Vanne, F. Vanneau beam feather (cf. It. Vanno a wing) fr. L. Vannus. See Etymology above] A wing with which the air is beaten. "[/Angels] on the air plumy vans received him. " "He wheeled in air, and stretched his vans in vain; His vans no longer could his flight sustain." (Dryden) Origin: L. Vannus a van, or fan for winnowing grain: cf. F. Van. Cf. Fan, Van a wing Winnow. <chemical> A shovel used in cleansing ore. Origin: Cornish. <chemical> To wash or cleanse, as a small portion of ore, on a shovel. Source: Websters Dictionary (01 Mar 1998) |
| van Bogaert encephalitis | <neurology> Chronic progressive illness seen in children a few years after measles infection and involving demyelination of the cerebral cortex. Virus apparently persists in brain cells: usually considered a slow virus disease. (18 Nov 1997) |
