Book Description
Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1 957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 29 (thesis year 1984) a total of 12,637 theses titles from 23 Canadian and 202 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 29 reports theses submitted in 1984, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.

Book Description
Design of packed-tower air-stripping systems for the removal of volatile contaminants from groundwaters requires knowledge of the equilibrium constant relating air and water concentrations (Henry's constant, H), and the applicable mass transfer coefficient (K sub 1a). The objectives of this research were: to evaluate the effects of temperature, ionic strength, and the mutual presence of other organics on the H-values of five volatile compounds of concern to the USAP; and to investigate the effects of temperature, packing size and type, liquid and air loadings, and the mutual presence of other organics on the K sub 1a values of these five compounds--tetrachloroethylene, trichloroethylene, 1,1,1-trichloroethane, chloroform, and methylene chloride. An innovative method for measuring Henry's constants was proposed and evaluated, termed Equilibrium Partitioning In Closed Systems (EPICS). This method relies upon measurement of the ratio of headspace concentrations from two equilibrated bottles containing equal solute masses, but possessing differing liquid volumes. H-values for the five compounds were measured over temperatures ranging from 10 to 30 C using both EPICS and batch, diffused-bubble stripping techniques. Temperature regressions for H were derived. Comparison between methods suggests that EPICS is as precise as the batch-stripping technique, and is probably more accurate, being free of mass transfer limitations. Liquid-phase diffusivity values were measured for the five study compounds at 20 C using a diaphragm diffusion cell.

Book Description
The past thirty years have witnessed a growing worldwide desire that po- tive actions be taken to restore and protect the environment from the degr- ing effects of all forms of pollution—air, water, soil, and noise. Because pollution is a direct or indirect consequence of waste, the seemingly idealistic demand for “zero discharge” can be construed as an unrealistic demand for zero waste. However, as long as waste continues to exist, we can only attempt to abate the subsequent pollution by converting it to a less noxious form. Three major questions usually arise when a particular type of pollution has been id- tified: (1) How serious is the pollution? (2) Is the technology to abate it ava- able? and (3) Do the costs of abatement justify the degree of abatement achieved? This book is one of the volumes of the Handbook of Environmental Engineering series. The principal intention of this series is to help readers f- mulate answers to the last two questions above. The traditional approach of applying tried-and-true solutions to specific pollution problems has been a major contributing factor to the success of en- ronmental engineering, and has accounted in large measure for the establi- ment of a “methodology of pollution control. ” However, the realization of the ever-increasing complexity and interrelated nature of current environmental problems renders it imperative that intelligent planning of pollution abatement systems be undertaken.
