Clamp-on device can detect gas flow at a lower pressure than previous devices Designed for applications such as natural gas, compressed air, and high-purity gas transmission and distribution, the ...

A new equation for accurate approximation of the Moody friction factor in the general gas-flow equation better approximates a wide range of Reynolds numbers than previously published equations. Other, ...

Hydrogen sulfide gas can induce a state of suspended animation in mice while maintaining normal blood pressure, a finding that researchers hope will one day help treat critically-ill patients and ...
