This book was released on 2012-12-06 with total page 407 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 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.

Download or read book Biodegradation written by W.B. Betts and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 245 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two major problems encountered as we approach a new century are the availability of resources for chemicals and energy, and environmental pollution. This book highlights the importance of biotransformation as a solution to these problems and considers traditionally separate areas as one interdependent discipline, in terms of the underlying mechanistic biochemistry and the research techniques employed. The provision of resources has largely centred around non-renewable materials, especially oil. Diminishing reserves of these, together with uncertainties of supply and cost have stimulated great interest in renewable resources. These are largely lignocellulosic materials (e.g. wood and straw) which are available through natural biomass turnover, farming and forestry and from wastes generated by industrial processes. An excellent example is that of kraft lignin, a by-product of pulp and paper production, amounting to 60 million tonnes per annum and which is largely wasted by burning or landfilling. This aromatic polymer has enormous potential as a feedstock to the chemical industry. Environmental pollution is no longer accepted as inevitable for a technological society. Over the past decade there has been a tremendous increase in awareness of the effects of pollution and public pressure has influenced both industry and government. However, to be realistic, it is not possible to replace all processes generating polluting wastes with clean alternatives. Instead, treatments of pollution, both at source and after an incident, are alternatives in many instances and a great deal of emphasis is currently being placed on these.
Download or read book Herbicide Residue Research in India written by Shobha Sondhia and published by Springer. This book was released on 2018-10-30 with total page 475 pages. Available in PDF, EPUB and Kindle. Book excerpt: Herbicides constitute about 60% of the total pesticides consumed globally. In India, the use of herbicides started initially in tea gardens and picked up in the 1970s, when the high-yielding varieties of rice and wheat were introduced. Presently, 67 herbicides are registered in the country for controlling weeds in crops including cereals, pulses, oilseeds, fibre and tuber crops, and also in the non-crop situations. These chemicals are becoming increasingly popular because of their efficiency and relatively low cost compared with manual or mechanical weeding operations. The contribution of herbicide to total pesticide use, which was only 10-15% during the first decade of the 21st century, has now increased to about 25% with an annual growth rate of 15-20%, which is much higher than insecticides and fungicides. Though the application of herbicides is minimizing yield loss to a great extent, their residues in the food chain and surface and groundwater create some environmental nuisance particularly to non-target organisms. Research on pesticide residues in India was started during 1970s, when such chemicals were introduced on a greater scale along with high-yielding variety seeds, irrigation and chemical fertilizers for increasing food production. However, the herbicide residue research was not given much emphasis until 1990s. The Indian Council of Agricultural Research initiated a national level programme known as All India Coordinated Research Project on Weed Management through the NRC-Weed Science as the main centre along with some centers of ICAR Institutes and state agricultural universities. Over the last two decades, adequate information was generated on estimation, degradation and mitigation of herbicide residues, which were documented in annual reports, bulletins, monographs and scientific articles. However, there was no consolidated compilation of all the available information providing a critical analysis of herbicide residues. Accordingly, an effort has been made in the publication to compile the available information on herbicide residues in India. This is the first report of its kind which presents the findings of herbicide residues and their interactions in the biotic and abiotic environment. There are 16 chapters contributed by the leading herbicide residue scientists, each describing the present status of herbicide use, crops and cropping systems, monitoring, degradation and mitigation, followed by conclusions and future lines of work. This book will be useful to the weed scientists in general and herbicide residue chemists in particular, besides the policy makers, students and all those concerned with the agricultural production in the country.

Download or read book Herbicides and Environment written by Andreas Kortekamp and published by BoD – Books on Demand. This book was released on 2011-01-08 with total page 764 pages. Available in PDF, EPUB and Kindle. Book excerpt: Herbicides are much more than just weed killers. They may exhibit beneficial or adverse effects on other organisms. Given their toxicological, environmental but also agricultural relevance, herbicides are an interesting field of activity not only for scientists working in the field of agriculture. It seems that the investigation of herbicide-induced effects on weeds, crop plants, ecosystems, microorganisms, and higher organism requires a multidisciplinary approach. Some important aspects regarding the multisided impacts of herbicides on the living world are highlighted in this book. I am sure that the readers will find a lot of helpful information, even if they are only slightly interested in the topic.
