3Tracer-gas leak testing method — As part of the recommended leak testing methods for nondestructive testing several tracer gas leak testing ones exist among which the methods of choice are: * Helium mass spectrometer or helium leak detection, providing the highest sensitivity *… …
4Pump leak model — The pump leak model is a mechanism for the reabsorption of sodium in the kidney nephrons, in order to achieve the euvolemic state.The pump is the active transport of sodium from the tubular cell into the interstitial space at the basolateral… …
5Gaseous diffusion — is a technology used to produce enriched uranium by forcing gaseous uranium hexafluoride, UF6, through semi permeable membranes. This produces a slight separation between the molecules containing uranium 235 and uranium 238. By use of a large… …
