The objective of this research was to demonstrate that electrokinetics can be used to remove colloidal coal and mineral particles from coal-washing ponds and lakes without the addition of chemical additives such as salts and polymeric flocculants. The specific objectives were: Design and develop a scaleable electrophoresis apparatus to clarify suspensions of colloidal coal and clay particles; Demonstrate the separation process using polluted waste water from the coal-washing facilities at the coal-fired power plants in Centralia, WA; Develop a mathematical model of the process to predict the rate of clarification and the suspension electrical properties needed for scale up.

Much of the authors work over the past five years has been aimed at bridging the gap between the exactly supersymmetric world of string theories and the world that is actually observed. Her report discusses the following subjects: (1) supersymmetry breaking; related work on the mass hierarchy and the relation between supersymmetry and grand unified theories; distinguishing between supersymmetric models; and the fundamental question of how gauge theories arise from D-branes.
