This book was released on 2012-12-06 with total page 411 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 32 (thesis year 1987) a total of 12,483 theses titles from 22 Canadian and 176 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 32 reports theses submitted in 1987, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.

This book was released on 2013-11-11 with total page 532 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Fifth International Biomineralization Symposium was held in May 1986 at The University of Texas at Arlington, Arlington, Texas. The chosen theme was the origin, evolution and modern aspects of biomineralization in plants and animals. Thus, the symposium was designed to bring together experts in ocean and atmospheric chemistry, geochemistry, paleontology, biology, medicine and related fields to share accumulated knowledge and to broaden research horizons. The contents of this volume reflect the diversified interests and views of contributors from these fields. Topics range from contrasting views of the origin of ocean chemistry, the cause or causes for the biomineralization among plants and animals, the evolution of style and structure of biomineralization, and the role of inorganic and organic compounds in biomineraliza tion. It was clear from those gathered in Arlington that the efforts of all researchers in any aspect of biomineralization can be strengthened and extended by greater exposure to the work of others in allied fields. At the time of this printing, several collaborative efforts have grown from interest and contacts developed during the symposium. Rex E. Crick viii ACKNOWLEDGEMENTS The symposium would not have occurred with the financial support of The Organized Research Fund of The University of Texas at Arlington and The Sea Grant Program administered by Texas A & M University. The staff of the Department of Geology of The University of Texas at Arlington were largely responsible for providing a pleasant atmosphere for learning.

Available in PDF, EPUB and Kindle. Book excerpt: Late Quaternary histories are investigated here for sediment cores from Lakes Huron and Michigan, using the oxygen- and carbon-isotope compositions of biogenic carbonates and the oxygen- and hydrogen-isotope compositions of porewater. Age models for these cores are based on sedimentological information, and where possible, radiocarbon and pollen dates. The Michigan Basin cores provide a thick record of the late Pleistocene, whereas the Huron Basin cores primarily record Holocene deposition. Taken together, the histories recorded in biogenic carbonates from these sediments provide a clear account of lakewater isotopic changes - and their significance - over much of the history of the Great Lakes Basin. Biogenic carbonates, and ostracodes in particular, serve as excellent recorders of lakewater!18O values. Modern specimens from Lake Huron have been used to assess non-equilibrium oxygen- and carbon-isotope fractionation effects during shell formation within this setting. This information provides improved ability to calculate the oxygenisotopic compositions of paleolakewater using fossil biogenic carbonates from the cores. The fossil shell compositions indicate intervals characterized by low!18O meltwater originating from the retreating Laurentide Ice Sheet and/or associated proglacial lakes, and periods dominated by higher!18O water that are more reflective of regional precipitation, runoff and climatic conditions. Differences in the oxygen- and carbonisotope compositions of deep- versus shallower-water ostracode species in the Michigan Basin cores suggest isotopic stratification of its lakewater during the late Pleistocene. Results for previously unstudied parts of the Huron Basin suggest that sub-basins acquired different oxygen-isotope compositions during periods of very low lake levels, reflecting different water sources and/or different conditions at such times. Early Holocene influxes of glacial meltwater into the Huron Basin, and to a lesser extent the Michigan Basin, correlate with major global climate perturbations that were likely triggered by release of large volumes of glacial meltwater into the Arctic and/or North Atlantic Oceans. Porewater did not preserve original lakewater!18O and!D values. These compositions are largely controlled by downward diffusion of modern lakewater.
