Steep Trails by John Muir

2019-12-5 ensp 0183 ensp The frost was intense and drifting snow dust made breathing at times rather difficult The snow was as dry as meal and the finer particles drifted freely rising high in the air while the larger portions of the crystals rolled like sand I frequently sank to my armpits between buried blocks of loose lava but generally only to my knees...

METHOD FOR PRODUCING BETA

2019-10-31 ensp 0183 ensp Specifically after rough crushing the composition may be crushed to a prescribed particle size with a usual crushing machine such as a ball mill a jet mill or a vibration mill Excessive crushing may cause defects on the surface of the fluorescent material particles and may result in a decrease in emission intensity...
