Two studies were conducted to quantify biological and behavioral effects resulting from exposure to controlled doses of marijuana smoke. In one study, puff volume (30, 60 and 90 ml) and in a second study, breathhold duration (0, 10 and 20 sec) were systematically varied while holding constant other smoking topography parameters (number of puffs = 10, interpuff interval = 60 sec and inhalation v...

Abnormal grain growth was studied in an Fe-1%Si alloy using automated Electron Backscattered Diffraction (EBSD). Industrially processed samples were temper rolled to reductions of 0%, 1.5% and 8% and then annealed in a range of atmospheres for various times followed by quenching in water. Abnormal grain growth was observed regardless of atmosphere although a moist hydrogen-nitrogen mixture resu...
