A mutual CO2-H2O solubility model was previously reported for application to CO2-enhanced geothermal systems. The ability of this model to predict PVT and caloric properties of the compressed gas phase is investigated. Compressibility factors of pure CO2 and CO2-H2O mixtures can generally be predicted within a few percent of reference and experimental data. Caloric data are also reasonably well...

Lithium-brine is an important potential source of lithium. Much research and investigation has been carried out aimed at lithium recovery from brine. Although the distribution and occurrence status of lithium in brine have important implications for lithium recovery, few reports had correlated to this issue. In this article, a study was carried out to explore the lithium migration behavior duri...

Dr. Class' resignation, which was precipitated, according to his prepared, statement, by "a growing conflict of philosophy between the President (Pitzer) and myself with respect to the practices and policies to be followed in the best interest of Jones College," will take effect at the end of this semester. Dr. Vandiver will serve as Master of Jones for the second semester tefore he assumes dut...

This paper seeks to improve on previous estimates of the impact of immigration on native wages by using an occupational segmentation approach that directly controls for regional migration and other shifts in native-born labor supply. The labor market is segmented by occupation in order to determine which, if any, native workers tend to be vulnerable to increased immigrant competition for jobs. ...

This study investigates the risky positioning behaviour of underground coal mine employees, specifically the behaviour of drivers of remote controlled continuous miners. The patterns of behaviour of these employees are of particular interest, not only because of a series of fatal accidents in New South Wales coal mines with such equipment, but also because of the lack of scientific enquiry of r...
