Source reduction

(Environmental Engineering) The elimination or reduction of the waste at the source by modification of the actual process which produces the waste.

Defect amplification

(Software Engineering) when a defect is introduced early in the software process and remains undetected, it often is amplified into multiple defects later in the software process

Reusability

(Software Engineering) the ability to reuse an already-existing program component in another application

Anaerobic process

(Environmental Engineering) A process which only occurs in the absence of molecular oxygen.

Maximum contaminant level (MCL)

(Environmental Engineering) The maximum allowable concentration of a given constituent in potable water.

Total suspended solids

(Environmental Engineering) (TSS) is the amount of suspended (filterable) matter in a water.

Reaeration

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

Absolute Volume

(Concrete Engineering) The volume of an ingredient in its solid state, without voids between individual pieces or particles, in the case of fluids, the cubic content occupied. In concrete, the actual volume occupied by the different ingredients determined by dividing the weight of each ingredient pounds, by ifs specific gravity, times the weight of one cubic foot of water in pounds. Example: Absolute Volume of one sack of cement equals: 94 ๗ (3.15X62.4) = 0.478 cubic feet

Bent Axis Pumps

(english) In this pump, the pistons are at an angle to the drive shaft and Thrust Plate. The piston block shaft is connected to the drive shaft by a universal joint, not shown. The drive shaft, thrust plate, piston block shaft, and piston block all revolve. The connecting rods are attached to the thrust plate and revolve with it, unlike the swash plate pump where the piston rods slide past a stationary swash plate. The outlet ports are semi-circular holes in the Valve Plate, shown on the far right of the animation on edge and in a head-on view below, right. As the pump revolves, half the pistons suck in fluid as they pass over the intake port. The other pistons discharge their fluid through the outlet port. This pump should be compared to the radial piston pump, swash plate pump, and wobble pump.

Line of Action:

(english) The line of action of a force is the infinite line defined by extending along the direction of the force from the point where the force acts.

Elastic Shortening

(Concrete Engineering) The shortening of a member in pre-stressed concrete which occurs on the application of forces induced by prestressing.

Toxicity

(Environmental Engineering) A U.S. EPA hazardous waste characteristic defined with a rigorous test procedure, the TCLP (for Toxicity Characteristic Leaching Procedure). In the procedure, a waste is extracted for 24 hours with an acetic acid solution. The acid extract is then analyzed for the presence of any of the contaminants listed in the procedure.
