(Software Engineering) a technique that distributes control and work in a top-down manner within a software architecture (used a part of structured analysis)
(english) Joining metals by fusion of nonferrous alloys that have melting points above 800 F (425C), but lower than those of the metals being joined. May be accomplished by a torch. Filler metal is ordinarily in rod form in torch brazing; whereas in furnace and dip brazing the work material is first assembled and the filler metal may then be applied as wire, washers, clips, bands, or may be bonded, as in brazing sheet.
(english) The resultant of a system of forces causing rotation without translation. A moment can be expressed as a couple.
(Environmental Engineering) Treatment of a waste in place, as opposed to pumping or digging the waste up and then treating it.
(english) A process for cleaning or finishing metal objects by use of an air blast or centrifugal wheel that throws abrasive particles against the surface of the work pieces. Small, irregular particles of steel or iron are used as the abrasive in grit blasting, and steel or iron balls in shot blasting.
(english) The mineral zircon silicate, ZrSiO4, a very high melting point acid refractory material used as a molding material in steel foundries.
(Concrete Engineering) A device for determining the consistency of fresh concrete. It is sometimes used as an alternative to the slump test.
(Concrete Engineering) A tool having a serrated face, as rows of pyramidal points, used to develop an architectural finish for concrete surfaces.
(Environmental Engineering) The National Pollutant Discharge Elimination System. The discharge criteria and permitting system established by the U.S. EPA as a result of the Clean Water Act and its subsequent amendments or the permit required by each discharger as a result of the Clean Water Act.
(Environmental Engineering) A submicroscopic genetic constituent which can alternate between two distinct phases. As a virus particle, or virion, it is DNA or RNA enveloped in an organic capsule. As an intracellular virus, it is viral DNA or RNA inserted into the host organisms DNA or RNA.
(english) The displacement and / or detachment of metallic particles from a surface as a consequence of being exposed to flowing fluids or gases.
(english) Appeaars like a series of waves and are created during rolling as a result of mechanical misalignment or cross-section irregularities in supply coil.
