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 28 (thesis year 1 983) a total of 10,661 theses titles from 26 Canadian and 197 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 28 reports theses submitted in-1983, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.

The use of plastics in agriculture – to increase crop output, improve food quality and improve sustainability – has grown substantially in both quantity and the range of applications. Many of the early researchers that conducted field research in the use of plastics in agriculture have either retired or are deceased. These early pioneers in plasticulture research, the basis of plant production using plastics, were very creative and persistent in discovering uses of plastics in agricultural applications. A Guide to the Manufacture, Performance, and Potential of Plastics in Agriculture contains both references not only to their accomplishments but also their publications. The book discusses plasticulture-the basis of plant production using plastics – including topics such as plastic mulch, row covers, drip irrigation, and high/low tunnels. It covers the process of producing polyethylene and polypropylene plastics that are used in plant and animal production agriculture, and the many uses of plastics in all aspects of agriculture, including plastic greenhouses, rigid mold plastics, disposal of plastics, and plastics in animal production. This book introduces a range of academics and industrial practitioners to the impact of plastics in agriculture, both historically and in a range of current applications. It also provides new perspectives on future developments to enable further research and application. It is an invaluable reference on the use of polyethylene, polypropylene films, and such products in all aspects of agricultural production. Discusses plasticulture, the basis of plant production using plastics, including topics such as plastic mulch, row covers, drip irrigation, and high/low tunnels Contains 10 chapters that cover the process of producing polyethylene and polypropylene plastics that are used in agriculture Covers the many uses of plastics in all aspects of agriculture, including plastic greenhouses, rigid mold plastics, disposal of plastics, and plastics in animal production
