Life cycle assessment (LCA) of production and processing in the food industry is an important tool for improving sustainability. Environmental assessment and management in the food industry reviews the advantages, challenges and different applications of LCA and related methods for environmental assessment, as well as key aspects of environmental management in this industry sector.Part one discusses the environmental impact of food production and processing, addressing issues such as nutrient management and water efficiency in agriculture. Chapters in Part two cover LCA methodology and challenges, with chapters focusing on different food industry sectors such as crop production, livestock and aquaculture. Part three addresses the applications of LCA and related approaches in the food industry, with chapters covering combining LCA with economic tools, ecodesign of food products and footprinting methods of assessment, among other topics. The final part of the book concentrates on environmental management in the food industry, including contributions on training, eco-labelling and establishing management systems.With its international team of editors and contributors, Environmental assessment and management in the food industry is an essential reference for anyone involved in environmental management in the food industry, and for those with an academic interest in sustainable food production.Reviews the advantages, challenges and different applications of LCA and related methods for environmental assessmentDiscusses the environmental impact of food production and processing, addressing issues such as nutrient management and water efficiency in agricultureExamines environmental management in the food industry, including contributions on training, eco-labelling and establishing management systems

On December 2-5, 1991, a Symposium on Thermal Stresses, Dynamics and Stability honoring Professor Bruno A. Boley on the occasion of his 65th birthday was held in Atlanta, Georgia during the Winter Annual Meeting of the American Society of Mechanical Engineers. The papers presented during the Symposium by some of Professor Boley's former students and colleagues cover those areas of applied mechanics where most of his contributions have been made over the years. These papers have been written in tribute to Professor Boley's distinguished scientific career and out of genuine affection and respect for him. The present volume consists of those Symposium papers that belong to the areas of Dynamics and Stability and constitute recent advances in the field. A special issue of the Journal of Thermal Stresses has been reserved for publication of the Symposium papers on Thermal Stresses, under the editorship of Professor R. B. Hetnarski. The present volume begins with a biographical sketch and bibliography of Professor Boley, along with a list of his doctoral students. Thirteen papers on dynamics and stability follow. The first four papers deal with wave propagation and vibration studies in solids and structures. The next two papers study wave propagation in fluids, while the seventh paper is concerned with the dynamic response of random media. Two papers dealing with structural vibrations exhibiting instability and one dealing with dynamic buckling delamination are presented next. The last three papers are concerned with instability in solids and structures.
