This volume encompasses and unites all the major topics relating to Insect Chemoreception. Part 1 addresses topics such as plant/insect interactions, pheromones, ultrastructure, electrophysiology and the biochemistry of chemoreceptors. Part 2 embraces applications of plant chemicals and cultivars in insect pest control, host plant resistance and pheromones. A concluding chapter discusses the scope and potential of genetic engineering. This comprehensive account of the major aspects of sustainable insect pest control, together with the key references cited, will point the way to relevant research projects, and provide an up-to-date awareness of recent developments in the field. Audience: Graduate students and researchers in insect chemoreception, chemical ecology and sustainable pest control.

Focusing on the different types of grassland farming and their impact on the environment, Environmental Impacts of Pasture-based Farming takes a broad and interdisciplinary view of the subject. The text is organized into two sections, the first addressing issues facing environmental quality, namely soil, water and air quality and socioeconomic impacts. The second section offers commentary on how the different pastoral sectors influence environmental issues. With highly tuned farm productive systems comes the risk of environmental impacts, and the purpose of this text is to highlight the areas with which these risks are associated and how best to mitigate them. While drawing attention to potential problems, chapter authors always remain conscious of the socio-economic needs of land users and the increasing world population and keep in mind that intense mitigation may be too restrictive on the farming system. This book takes an unbiased approach to improving management of grazed land and incorporates research from environmental science, agriculture, soil science and ecology.

In the last 20 years, there has been a remarkable emergence of innovations and technological advances that are generating promising changes and opportunities for sustainable agriculture, yet at the same time the agricultural sector worldwide faces numerous daunting challenges. Not only is the agricultural sector expected to produce adequate food, fiber, and feed, and contribute to biofuels to meet the needs of a rising global population, it is expected to do so under increasingly scarce natural resources and climate change. Growing awareness of the unintended impacts associated with some agricultural production practices has led to heightened societal expectations for improved environmental, community, labor, and animal welfare standards in agriculture. Toward Sustainable Agricultural Systems in the 21st Century assesses the scientific evidence for the strengths and weaknesses of different production, marketing, and policy approaches for improving and reducing the costs and unintended consequences of agricultural production. It discusses the principles underlying farming systems and practices that could improve the sustainability. It also explores how those lessons learned could be applied to agriculture in different regional and international settings, with an emphasis on sub-Saharan Africa. By focusing on a systems approach to improving the sustainability of U.S. agriculture, this book can have a profound impact on the development and implementation of sustainable farming systems. Toward Sustainable Agricultural Systems in the 21st Century serves as a valuable resource for policy makers, farmers, experts in food production and agribusiness, and federal regulatory agencies.

Protecting the reproductive potential of young patients undergoing cancer therapy is increasingly important. With modern treatment protocols, 80% of patients can be expected to survive. It has been estimated that up to one in 250 young adults will be a survivor of childhood cancer in the future; infertility, however, may be a consequence. As a wide range of fertility preservation methods are increasingly offered by clinicians, this systematic and comprehensive textbook dealing with the cryobiology, technology and clinical approach to this therapy will be essential reading to infertility specialists, embryologists, oncologists, cryobiologists, ObGyns, andrologists, and urologists with an interest in fertility preservation. Fertility Cryopreservation reviews all the techniques of this increasingly important field within reproductive medicine. It covers the basic principles of pertinent cryobiology, and contains major sections on the different therapies available, written by international specialists combining experience from both academic centers and commercial industries.

The accurate measurement of additives in food is essential in meeting both regulatory requirements and the need of consumers for accurate information about the products they eat. Whilst there are established methods of analysis for many additives, others lack agreed or complete methods because of the complexity of the additive or the food matrix to which such additives are commonly added. Analytical methods for food additives addresses this important problem for 26 major additives. In each case, the authors review current research to establish the best available methods and how they should be used. The book covers a wide range of additives, from azorubine and adipic acid to sunset yellow and saccharin. Each chapter reviews the range of current analytical methods, sets out their performance characteristics, procedures and parameters, and provides recommendations on best practice and future research. Analytical methods for food additives is a standard work for the food industry in ensuring the accurate measurement of additives in foods. Discusses methods of analysis for 30 major additives where methods are incomplete or deficient Reviews current techniques, their respective strengths and weaknesses Detailed tables summarising particular methods, statistical parameters for measurement and performance characteristics

In order to meet increasing global demand for meat and animal by-products increasingly intensive animal production is necessary. Creating a sustainable system in animal agriculture that works in different production environments is a major challenge for animal scientists. This book draws together themes on sustainability that have emerged as the most pressing in recent years. Addressing practical topics such as air quality, manure management, animal feeds, production efficiency, environmental sustainability, biotechnology issues, animal welfare concerns, societal impacts and an analysis of the data used to assess the economic sustainability of farms.

The potential for using fusion energy to produce commercial electric power was first explored in the 1950s. Harnessing fusion energy offers the prospect of a nearly carbon-free energy source with a virtually unlimited supply of fuel. Unlike nuclear fission plants, appropriately designed fusion power plants would not produce the large amounts of high-level nuclear waste that requires long-term disposal. Due to these prospects, many nations have initiated research and development (R&D) programs aimed at developing fusion as an energy source. Two R&D approaches are being explored: magnetic fusion energy (MFE) and inertial fusion energy (IFE). An Assessment of the Prospects for Inertial Fusion Energy describes and assesses the current status of IFE research in the United States; compares the various technical approaches to IFE; and identifies the scientific and engineering challenges associated with developing inertial confinement fusion (ICF) in particular as an energy source. It also provides guidance on an R&D roadmap at the conceptual level for a national program focusing on the design and construction of an inertial fusion energy demonstration plant.
