Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Oata Analysis and Synthesis (CINOAS) * 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 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 33 (thesis year 1988) a total of 13,273 theses titles from 23 Canadian and 1 85 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 33 reports theses submitted in 1988, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.

Although extensive work addressing petrology, diagenesis and depositional environment of the Catahoula Formation in south and central Texas has been completed, limited information is present for units of east Texas, specifically Jasper County, Texas. Through field investigation, optical microscopy of thin sections, XRPD of clay sized fraction, and SEM, this study examines the petrology, diagenetic history, and depositional environment of the Catahoula Formation in Jasper County, Texas. Sandstone units are dominantly mature medium-fine grained sub-litharenites consisting of approximately 85% quartz, 4% feldspar, and 11% rock fragments (mean %). Quartz types are monocrystalline, 95%; and polycrystalline, 5%. Monocrystalline quartz types consist of undulose extinction, 36%; straight extinction, 39%; rutilated quartz, 17%; and coarse-medium silt sized quartz, 8%. Feldspars are 97% alkali and 3% plagioclase. Rock fragments are 88% sedimentary (SRF) and 12% volcanic (VRF). SRF consist of 66% chert and 34% lithic grains. VRF are vitric air-fall tephra. Devitrification of volcanic tephra and dissolution of feldspars are the primary sources of authigenic montmorillonite, kaolinite, and opal-CT cements. Units were never buried to significant depth based on absence of illite, quartz overgrowths, and solution contacts. Depositional facies are crevasse splay, floodplain, lacustrine, and fluvial channel.

With more than 500 species distributed all around the Northern Hemisphere, the genus Quercus L. is a dominant element of a wide variety of habitats including temperate, tropical, subtropical and mediterranean forests and woodlands. As the fossil record reflects, oaks were usual from the Oligocene onwards, showing the high ability of the genus to colonize new and different habitats. Such diversity and ecological amplitude makes genus Quercus an excellent framework for comparative ecophysiological studies, allowing the analysis of many mechanisms that are found in different oaks at different level (leaf or stem). The combination of several morphological and physiological attributes defines the existence of different functional types within the genus, which are characteristic of specific phytoclimates. From a landscape perspective, oak forests and woodlands are threatened by many factors that can compromise their future: a limited regeneration, massive decline processes, mostly triggered by adverse climatic events or the competence with other broad-leaved trees and conifer species. The knowledge of all these facts can allow for a better management of the oak forests in the future.
