1696 Microstructural distribution of sulfur during the retorting and oxidation of oil shale1982-11Oil shale; Retorting; Combustion; Sulfur; Microstructural distributionWe report here the first direct observations of the mineralogical and chemical changes in oil shale caused by retorting and combustion. Electron microprobe and scanning electron microscopy techniques were used to examine a portion of the surface area of a sample in the raw shale state, the same area...
1697 Migration in Utah1988-08For many years Utah has been among the fastest growing states in the country. Although the primary reason for Utah's high growth is the rate of natural increase caused by Utah's high birth rate, migration is the other component of population change. This report examines some of the major sources of ...
