Applied Process Design for Chemical and Petrochemical Plants: Volume 3

An Introduction to Field Quantization is an introductory discussion of field quantization and problems closely related to it. Field quantization establishes a commutation relation of the field and finds an operator in such a manner that the Heisenberg equation of motion is satisfied. This book contains eight chapters and begins with a review of the quantization of the Schroedinger field and the close relation between quantized field theory and the many-body theory in quantum mechanics. These topics are followed by discussions of the quantization of the radiation field and the field of lattice vibrations in a solid. The succeeding chapter deals with the familiar linear equations in relativistic field theory and the deduction of certain spin independent theories, which these fields have in common. Other chapter explores the derivation technique of the conservation laws for fields with arbitrary spin directly from the field equations without explicit recourse to Noether's theorem using a configuration space version of the generalized Ward identity. The discussion then shifts to the relativistic quantization method applicable to any field with arbitrary spin; the transformation of various fields under the Lorentz transformation; and a general method for constructing wave functions explicitly, as well as the application of this method to several examples. The concluding chapter focuses on the quantization of interacting fields. This book will prove useful to physicists and researchers.

"Insect Pests of Potato: Biology and Management provides a comprehensive source of up-to-date scientific information on the biology and management of insects attacking potato crops, with an international and expert cast of contributors providing its contents. This book presents a complete review of the scientific literature from the considerable research effort over the last 15 years, providing the necessary background information to the subject of studying the biology management of insect pests of potatoes, assessment of recent scientific advances, and a list of further readings. This comprehensive review will be of great benefit to a variety of scientists involved in potato research and production, as well as to those facing similar issues in other crop systems. Key Features. Written by top experts in the field, this is the only publication covering the biology, ecology and management of all major potato pests. Emphasizes ecological and evolutionary approaches to pest management. Summarizes information from hard-to-get publications in China, India, and Russia"

"Neither pest management nor resistance management can occur with only an understanding of pest biology. For years, entomologists have understood, with their use of economic thresholds, that at least a minimal use of economics was necessary for proper integrated pest management. IRM is even more complicated and dependent on understanding and using socioeconomic factors. The new edition of Insect Resistance Management addresses these issues and much more. Many new ideas, facts and case studies have been developed since the previous edition of Insect Resistance Management published. With a new chapter focusing on Resistance Mechanisms Related to Plant-incorporated Toxins and heavily expanded revisions of several existing chapters, this new volume will be an invaluable resource for IRM researchers, practitioners, professors and advanced students. Authors in this edition include professors at major universities, leaders in the chemical and seed industry, evolutionary biologists and active IRM practitioners. This revision also contains more information about IRM outside North America, and a modeling chapter contains a large new section on uncertainty analysis, a subject recently emphasized by the U.S. Environmental Protection Agency. The final chapter contains a section on insecticidal seed treatments. No other book has the breadth of coverage of Insect Resistance Management, 2e. It not only covers molecular to economic issues, but also transgenic crops, seed treatments and other pest management tactics such as crop rotation. Major themes continuing from the first edition include the importance of using IRM in the integrated pest management paradigm, the need to study and account for pest behavior, and the influence of human behavior and decision making in IRM. Key Features. Provides insights from the history of insect resistance management (IRM) to the latest science. Includes contributions from experts on ecological aspects of IRM, molecular and population genetics, economics, and IRM social issues. Offers biochemistry and molecular genetics of insecticides presented with an emphasis on recent research. Encourages scientists and stakeholders to implement and coordinate strategies based on local social conditions"

Available water disinfection systems rely mainly on large-scale filtration and the combination of filtration (to remove solids), and subsequent application of chemical disinfectants. This has proven to produce water of acceptable quality. Important points for application in household systems are low complexity, few training requirements, and easy transportation and distribution as well as a sufficiently high acceptance by the user. Written and endorsed by the European Federation of Food Science and Technology this book compares a variety of purification systems. There is a growing evidence base on targeting water quality improvements to maximize health benefits, and it is believed that 4% of the global disease burden could be prevented by improving water supply, sanitation, and hygiene. Better tools and procedures to improve and protect drinking-water quality at the community and urban level, for example, through Water Safety Plans include the availability of simple and inexpensive approaches to treat and safely store water at the household-level.

"Understanding the causes and contributing factors leading to outbreaks of food-borne illness associated with contamination of fresh produce is a worldwide challenge for everyone from the growers of fresh-cut produce through the entire production and delivery process. The premise of The Produce Contamination Problem is that when human pathogen contamination of fresh produce occurs, it is extremely difficult to reduce pathogen levels sufficiently to assure microbiological safety with the currently available technologies. A wiser strategy would be to avoid crop production conditions that result in microbial contamination to start. These critical, problem-oriented chapters have been written by researchers active in the areas of food safety and microbial contamination during production, harvesting, packing and fresh-cut processing of horticultural crops, and were designed to provide methods of contamination avoidance. Coverage includes policy and practices in the United States, Mexico and Central America, Europe, and Japan. Key Features. Addresses food-borne contaminations from a prevention view, providing proactive solutions to the problems. Covers core sources of contamination and methods for identifying those sources. Includes best practice and regulatory information"
