Glossary

Thickness of a liquid; determines its internal resistance to shear forces. The tendency of a fluid to resist flowing because of molecular attraction (cohesion).

A fluid property that relates the magnitude of fluid shear stresses to the fluid strain rate, or more simply, to the spatial rate of change in the fluid velocity field.

The part of the electromagnetic spectrum with wavelengths between 380 nm and 750 nm and perceived by the human eye.

Identification number of the protocol visit for which the investigational products are intended.

Term coined in 1911 (vita, Latin word for life, and the chemical term amine) by polish biochemist, Casimir Funk, represents one of a group of organic substances, some of which are of unknown composition, present in minute amount in natural foodstuffs which are essential to normal metabolism. A lack of vitamins in the diet causes deficiency diseases.Vitamins are commonly classified into two groups, the fat-soluble, and the water-soluble. Vitamins A, D, E, and K are fat-soluble. Vitamin C and members of the vitamin B complex group are water-soluble. In general, the vitamins play catalytic and regulatory roles in the body’s metabolism. Among the water-soluble vitamins, the B vitamins apparently function as coenzymes. Vitamin’s C coenzyme role, if any, has not been established. Part of the importance of vitamin C to the body may result from its strong antioxidant action. The actions of the fat-soluble vitamins are less well understood. Some of them, too, may contribute to enzyme activity, and some of them are essential to the functioning of cellular membranes.

A large group of water soluble vitamins that function as co-enzymes, including thiamine (B1); riboflavin or vitamin G (B2); niacin or nicotinic acid (B3); pantothenic acid (B5); pyridoxine (B6); cyanocobalamin (B12); biotin or vitamin H; folic acid or vitamin M (Bc); inositol; choline; and others.

An enclosure, container, or structure adapted or prepared for keeping or raising and observing animals under semi natural conditions, especially for laboratory research.

The maximal rate of an enzyme-catalyzed reaction. Vmax is the product of Eo (the total amount of enzyme) times the value of Keat (the catalytic rate constant).

Virtual Memory System

A short DNA sequence that is present as tandem repeats and in highly variable copy number.

Volatile Organic Compound

A measure of how quickly a substance forms vapors at ordinary temperatures. The more volatile the substance is, the faster it evaporates, and the higher the concentrations of vapor (gas) in the air.

The conversion of a solid or liquid into a gas or vapor.

(ANSI) A portion of data, together with its data carrier, that can be handled conveniently as a unit; e.g., a reel of magnetic tape, a disk pack, a diskette.

Testing designed to challenge a system's ability to manage the maximum amount of data over a period of time. This type of testing also evaluates a system's ability to handle overload situations in an orderly fashion.

The water content of a compressed gas may be specified as mass per unit volume (mg-m-3) at 1013 mbar and at either 15 or 20 °C (59 or 68 °F)(also see: Moisture Content)

Free of coercion, duress, or undue inducement. Used in the research context to refer to a subject's decision to participate (or to continue to participate) in a research activity.
