Fuel temperature coefficient of reactivity — is the change in reactivity of the nuclear fuel per degree change in the fuel temperature. The coefficient quantifies the amount of neutrons that the nuclear fuel (uranium 238) absorbs from the fission process as the fuel temperature increases.… … Wikipedia
Virtual reality cue reactivity — (VRCR) is an innovative computer enhanced methodology used to assess behavioral and physiological reactivity to drug and alcohol triggers (cues). Studies indicate that cue reactivity a response to the presentation of various visual, auditory,… … Wikipedia
Standard enthalpy change of formation (data table) — These tables include heat of formation data gathered from a variety of sources, including the primary and secondary literature, as well as the NIST Chemistry WebBook.
