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 1957, 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 thougtit 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 31 (thesis year 1986) a total of 11 ,480 theses titles trom 24 Canadian and 182 United States universities. We are sure that this broader base tor these titles reported will greatly enhance the value ot this important annual reterence work. While Volume 31 reports theses submitted in 1986, on occasion, certain univer sities do re port theses submitted in previousyears but not reported at the time.

Book Description
The ocean has absorbed a significant portion of all human-made carbon dioxide emissions. This benefits human society by moderating the rate of climate change, but also causes unprecedented changes to ocean chemistry. Carbon dioxide taken up by the ocean decreases the pH of the water and leads to a suite of chemical changes collectively known as ocean acidification. The long term consequences of ocean acidification are not known, but are expected to result in changes to many ecosystems and the services they provide to society. Ocean Acidification: A National Strategy to Meet the Challenges of a Changing Ocean reviews the current state of knowledge, explores gaps in understanding, and identifies several key findings. Like climate change, ocean acidification is a growing global problem that will intensify with continued CO2 emissions and has the potential to change marine ecosystems and affect benefits to society. The federal government has taken positive initial steps by developing a national ocean acidification program, but more information is needed to fully understand and address the threat that ocean acidification may pose to marine ecosystems and the services they provide. In addition, a global observation network of chemical and biological sensors is needed to monitor changes in ocean conditions attributable to acidification.

Book Description
The book presents chapters from world leaders on water desalination advances with respect to processes, separations materials, and energy and environmental considerations. It provides a balanced discussion of the mature and newer desalination technologies and provides a fundamental assessment of the potential of emerging approaches. Realistic assessments for the feasibility of energy extraction from salinity gradients, desalting high salinity source water, membrane distillation, capacitive deionization, are among the topics discussed. Also, among the topics discussed in the book are recent advances in the desalination application of nanomaterials, carbon nanotubes, and surface structuring of membranes.

Book Description
Over the past few decades, dissolved organic carbon (DOC) concentrations in headwater streams in the northern hemisphere changed. Because these changes in DOC coincided with decreased acid deposition, a potential link was proposed early on. More recent research indicated that catchment attributes, especially soil characteristics and the presence of Ca-bearing minerals, play an important role in modulating DOC release from watersheds, but further research is necessary. To investigate the role of catchment characteristics on DOC dynamics, I use several watersheds in the Northeastern United States with similar attributes and well-constrained differences. Sleepers River Research Watershed (SRRW) has naturally occurring Calcium (Ca) bearing minerals versus Hubbard Brook Experimental Forest (HBEF) which has experimentally added Ca minerals in one watershed. To assess differences in long-term stream DOC trends in response to shifts in acid deposition, I use stream pH and flow-adjusted DOC stream water concentrations and performed Seasonal Kendall tests. I complement these analyses with experiments on soil cores across watersheds at SRRW and HBEF, seasons (SRRW only), and landscape positions. Despite similar increasing pH trends, SRRW and HBEF have contrasting long-term DOC responses. My results show that all watersheds show a significant increase in DOC, but the timing and magnitude of this increase vary. My soil experiments with simulated acidification and recovery treatments indicate SRRW varies significantly by season, and generally, recovery solutions extract more DOC. In contrast HBEF soils, landscape positions largely influenced DOC export (and aggregate sizes). I also investigate these findings with a conceptual lens of resistance and resilience as these are widely used concepts to evaluate response to disturbances. In this context, I discuss the long-term data for all watersheds and provide ideas for integrating experimental data in the timeline of changes in atmospheric deposition.
