Blowhole

(english) A defect in a casting caused by trapped steam or gas.

Mixed liquor suspended solids (MLSS)

(Environmental Engineering) The total suspended solids concentration in the activated sludge tank.

Total dissolved solids

(Environmental Engineering) (TDS) is the amount of dissolved matter in the water.

Make-buy decision

(Software Engineering) determining whether software should be built internally, acquired, contracted or built from reusable components

Billet container

(english) The part of the extrusion press into which the billet to be extruded is placed.

Blue Annealing

(english) Heating hot rolled ferrous sheet in an open furnace to a temperature within the transformation range and then cooling in air, in order to soften the metal. The formation of a bluish oxide on the surface is incidental.

Classes - a basic construct in object

(Software Engineering) oriented methods that categorizes elements of the problem

Aging 2

(english) A change in properties that occurs at ambient or moderately elevated temperatures after hot working or a heat treating operation (quench aging in ferrous alloys), or after a cold working operation (strain aging). The change in properties is often, but not always, due to a phase change (precipitation), but does not involve a change in chemical composition. In a metal or alloy, a change in properties that generally occurs slowly at room temperature and more rapidly at higher temperatures.

Support:

(english) A support contributes to keeping a structure in place by restraining one or more degrees of freedom. In a structural model, supports represent boundary entities which are not included in the model itself, e.g., foundations, abutments, or the earth itself. For each restrained translation degree of freedom at a support, there is a corresponding reaction force; for each restrained rotation degree of freedom, there is a reaction moment.

Component (of a vector):

(english) Any vector can be expressed as a collection of vectors whose sum is equal to the original vector. Each vector in this collection is a component of the original vector. It is common to express a vector in terms of components which are parallel to the x and y axes.

Boron (chemical symbol B)

(english) Element N. 5 of the periodic system. Atomic weight 10.82. It is gray in color, ignites at about 1112 (degrees) F. and burns with a brilliant green flame, but its melting point in a non-oxidizing atmosphere is about 4000 (degrees) F. Boron is used in steel in minute quantities for one purpose only- to increase the hardenability as in case hardening and to increase strength and hardness penetration.
