Stiffness:

(english) This is a general term which may be applied to materials or structures. When a force is applied to a structure, there is a displacement in the direction of the force; stiffness is the ratio of the force divided by the displacement. High stiffness means that a large force produces a small displacement. When discussing the stiffness of a material, the concept is the same, except that stress substitutes for force, and strain substitutes for displacement; see modulus of elasticity.

Back-up Balance

(english) Cylinders that supply the force used to hold the back-up rolls up in place.

Brake Press Bending

(english) An operation which produces various degree bends when fabricating parts from steel.

Reaeration

(Environmental Engineering) The dissolving of molecular oxygen from the atmosphere into the water.

Portability

(Software Engineering) the ability to transport software from one target environment to another

Spall

(Concrete Engineering) A fragment, usually of flaky shape, detached from a larger mass by pressure, expansion from within the larger mass, a blow, or by the action of weather.

Colloids

(Environmental Engineering) Small particles which have a negligible settling velocity. These particles have a very small mass so gravitational force is low compared to surface frictional forces. Typical colloidal sizes range from 10-3 mm to 1 mm.

Gas stripping

(Environmental Engineering) Gas transfer of an undesirable gas from a water stream to the atmosphere.

Producers

(Environmental Engineering) Autotrophic organisms which produce protoplasm using inorganic carbon and energy from the sun.

Biosynthesis

(Environmental Engineering) Catabolism, the production of new cellular materials from other organic or inorganic chemicals.

Anabolism

(Environmental Engineering) Biosynthesis, the production of new cellular materials from other organic or inorganic chemicals.

Chemotroph

(Environmental Engineering) Organisms which obtain energy from the metabolism of chemicals, either organic or inorganic.
