The aim of this book is to introduce the use of green solvents throughout chemistry and to provide a comprehensive reference for solvents currently applicable in green chemistry. The first section covers solvents in chemical perspective, and the second section is a guide to green solvents. Overall, this volume defines characteristics of green solvents and their current usage, and explores their importance ecologically and economically. It includes a full range of commercial, industrial, and academic green solvents, and discusses solvents in specific commercial and non-commercial practices. Green Solvents for Chemistry differs from other works on solvents in that only solvents for green chemistry are included along with their chemical properties and toxicological issues.
Prepared by the Task Committee on Recent Advances in Canal Automation of the Irrigation Delivery and Drainage Systems Committee of the Irrigation and Drainage Council of the Environmental and Water Resources Institute of ASCE Canal Automation for Irrigation Systems focuses on the technical aspects of modernizing irrigation systems through use of automated canal control systems. Canal automation has always offered an opportunity to save water and improve the efficiency of irrigation water supply projects or irrigation district operations. Recent technological and engineering advances now enable more accurate control of water deliveries throughout all parts of an irrigation project. Using information collected from irrigation systems around the world in conjunction with new advances in control theory research, this Manual of Practice examines how and when to implement canal automation within the context of canal modernization. Topics include: the modernization process, constraints, and concepts; survey of irrigation physical infrastructure; SCADA systems; control operation concepts; canal hydraulic properties; control methods; verification of controller performance; and implementation of control systems. MOP 131 is an essential reference for professionals in agricultural and irrigation engineering, as well as owners, managers, and operators of irrigation water delivery systems.
Military demolitions are the destruction by fire, water, explosive, and mechanical means of areas, structures, facilities, or materials to accomplish a military objective. The U.S. Army Explosives and Demolitions Handbook is a guide to the use of explosives in the destruction of military obstacles from the Department of the U.S. Army. This guide includes information on types, characteristics, and uses of explosives and auxiliary equipment; preparation, placement, and firing of charges; safety precautions; handling, transportation, and storage of explosives; deliberate and hasty demolition methods; and much more. Applicable to nuclear and nonnuclear warfare, and having offensive and defensive uses, the knowledge one will come away with from reading this handbook is invaluable.
Ten years after the publication of the first edition of Fundamentals of Food Process Engineering, there have been significant changes in both food science education and the food industry itself. Students now in the food science curric ulum are generally better prepared mathematically than their counterparts two decades ago. The food science curriculum in most schools in the United States has split into science and business options, with students in the science option following the Institute of Food Technologists' minimum requirements. The minimum requirements include the food engineering course, thus students en rolled in food engineering are generally better than average, and can be chal lenged with more rigor in the course material. The food industry itself has changed. Traditionally, the food industry has been primarily involved in the canning and freezing of agricultural commodi ties, and a company's operations generally remain within a single commodity. Now, the industry is becoming more diversified, with many companies involved in operations involving more than one type of commodity. A number of for mulated food products are now made where the commodity connection becomes obscure. The ability to solve problems is a valued asset in a technologist, and often, solving problems involves nothing more than applying principles learned in other areas to the problem at hand. A principle that may have been commonly used with one commodity may also be applied to another commodity to produce unique products.

Mechanical and electrical systems in architecture, engineering, and construction is intended for everyone involved in the construction industry. The book contains materials for those interested in the design of building electrical, lighting, plumbing, HVAC, fire protection, and telecommunications systems to those who must understand building mechanical and electrical materials and equipment in order to successfully envision, design, draw, construct, or operate a building or project.
This book discusses occupational health and safety, including occupational policies, legislative acts, and laws for protection of workers. Epidemiology and toxicology are examples of two fields that make contributions to exposure assessments and illuminate the adverse health effects associated with work-related exposures. Among the adverse health outcomes that have been linked with the work environment are cancer, respiratory illness, and reproductive abnormalities. Unintentional injuries are one of the leading causes of work-related morbidity and mortality, but the psychological and social environment can also affect the health of workers by influencing levels of stress and morale. Methods have been developed to reduce exposures to hazards and increase occupational safety through redesign of the work environment, introduction of engineering controls, and limiting exposures to physical, microbial, and chemical agents. --
