Glossary

A packaged functional hardware unit suitable for use with other components.

A container which can be transported by truck or railway and which is equipped with the equipment necessary to perform the operation for which it is designed.

A major section of a plant resulting from a series of remote assembly operations and may include portions of many systems; usually the largest transportable unit or component of a facility.

A table which provides a graphic illustration of the data elements whose values are input to and output from a module.

(IEEE) Testing of an individual hardware or software components or groups of related components.

A measure of the rigidity of metal. Ratio of stress, within proportional limit, to corresponding strain. Specifically, the modulus obtained in tension or compression is Young's modulus, stretch modulus or modulus of extensibility; the modulus obtained in torsion or shear is modulus of rigidity, shear modulus or modulus of torsion; the modulus covering the ratio of the mean normal stress to the change in volume per unit volume is the bulk modulus. The tangent modulus and secant modulus are not restricted within the proportional limit; the former is the slope of the stress-strain curve at a specified point; the latter is the slope of a line from the origin to a specified point on the stress-strain curve. Also called elastic modulus and coefficient of elasticity.

Force which would be required to stretch a substance to double its normal length, on the assumption that it would remain perfectly elastic, i.e., obey Hooke's Law throughout the twist. The ratio of stress to strain within the perfectly elastic range.

One of the portions into which something is divided; a component, part, or fraction. In chemistry, a specific section of a molecule, usually complex, that has a characteristic chemical effect or pharmacological property.

A binary mixture of dry air and water vapor. Each component behaves as if the other is not present and each occupies the complete volume of the mixture.(also see: Dry Air)

Abbreviation for gram molecule.

The number of mols of the component in question divided by the total mols of all components present.

Pertaining to or characterized by molality.

The concentration of a solution expressed in mols per kilogram of pure solvent.

A concentration of 1 gram-molecular weight (1 mol) of solute per liter of solution.

The concentration of a solution expressed in mols per liter of solution.

Excess material that is greater than the designed geometry of a part that is formed in the molding process.

A seal that is manufactured by forming in a mating cavity.

Filamentous fungi that have a mycelial structure.

One gram molecular weight of a compound.

The study of the structure, function, and makeup of biologically important molecules.

Molecular (chemical, non-particulate) substances that can have a deleterious effect on the product, process or equipment.

The development of transgenic animals to produce human proteins for medical use.

Deals with the study of the nature and biochemistry of genetic material. Includes the technologies of genetic engineering.

The weight of a molecule that may be calculated as the sum of the atomic weights of its constituent atoms. Atomic weight is the weight of an element in relation to some element taken as the standard, usually oxygen (16) or carbon (12).
