The purpose of this paper is to examine the cross-country relationship between income inequality and selected socioeconomic variables reflecting the level of economic development. The first chapter introduces some theoretical approaches to income distribution and poses problems regarding income inequalities across countries. The second chapter surveys cross-country studies of income inequalities conducted by previous researchers. The third chapter covers statistical methodology. Chapter four analyzes statistical results of multiple regression. The final chapter is intended for summary, conclusion, and recommendations.

A study was undertaken to examine the desorption/ iffusion of benzene after simulated ground water remediation in aquifer material of differing carbon content using column experiments and comparing the results to batch experiments and adsorption empirical relationships. It was hypothesized that the organic carbon of the aquifer material will affect desorption/diffusion. Results from the column experiment indicated no significant difference in the increase benzene concentrations after remediation between aquifer materials of differing carbon content, however, a significant increase in benzene concentration was observed for all aquifer material. Fair agreement of retardation factors was observed between empirical relationships and batch and column experiments. However, the desorption phase of the batch experiment showed hysteresis and seemed to differ from the column experiment.
