The issuance of a drawing from the engineering/design activity to the production activity. In other words, the event when a draft becomes a completed, official document. A stamp on the drawing saying "ISSUED" documents that RTP has occurred. RTV: room-temperature vulcanizing; return to vendor: 1. RTV sealants, a way to seal joints. 2.

The table usually lists only one name and symbol that is most commonly used. The final column lists some special properties that some of the quantities have, such as their scaling behavior (i.e. whether the quantity is intensive or extensive ), their transformation properties (i.e. whether the quantity is a scalar , vector , matrix or tensor ...
A branch of physics that studies atoms as isolated systems of electrons and an atomic nucleus. Compare nuclear physics. atomic structure atomic weight (A) The sum total of protons (or electrons) and neutrons within an atom. audio frequency A periodic vibration whose frequency is in the band audible to the average human, the human hearing range.
Mincer: A software package using FORM to compute massless propagator diagrams with up to three loops. FORM has been the essential tool to calculate the higher-order QCD beta function . The mathematical structure of multiple zeta values has been researched with dedicated FORM programs.
