If this problem happens to be essentially identical to a previous problem, which you were trained to solve, clearly you will have no difficulty. The chance is small that a given problem will be an exact replica of a familiar problem.

We have attempted to provide a concise and up to date account of human viruses in the environment with attention to basic tools now available for monitoring viruses. We have aimed this introductory volume at young students, teachers and investigators in microbiology, virology, environmental engineering and health sciences. As the routes for virus dissemination become more varied, there is an enhanced potential for causing infection in humans. Improvement in the development of control strategies will alleviate the magnitude of viral pollution of the environment. This volume will introduce the reader to an area of science which of necessity must utilize a variety of disciplines. V.CHALAPATIRAO JOSEPH L.

This short book attempts to give a reader who has a basic biochemical and microbiological background (one to two years at University level) an idea of the ecological, biochemical, physiological and biotechnological importance of methane, methanol and related compounds in the microbial world.

The engineering designer is always limited by the properties of available materials. The engineer must know this if he is to make intelligent use of the data on properties of materials that he finds in handbooks and tables, and if he is to exploit successfully new materials as they become available.

Materials Science has now become established as a discipline in its own right as well as being of increasing importance in the fields of Physics, Chemistry and Engineering. Electrical engineers working in the field of materials applications may well find it useful as a guide to modern thinking about materials and their properties.

After the death of Dr. Littlefield it was decided that I should undertake the revision ofthe whole of Atomic and Nuclear Physics: an Introduction for the third edition, and it was soon apparent that major changes were necessary.

A significant list of fiber optics terms and definitions, NBS Handbook 140, Optical Waveguide Communications Glossary, was issued in 1982 by the National Bureau of Standards, now the National Institute of Standards and Technology.

It covers systems used throughout the world in chapters detailing the latest on basic system design, baseband transmissions, and digital radio and cable systems.

This book provides practical, up-to-date information that helps in the successful management of diseases on food, fibre and landscape plants for students who do not have a strong background in the biological sciences.

This guide provides information on terms used in basic and clinical nutrition and diet therapy, including charts of RDAs and dietary guidelines. Nearly 4000 terms are covered, ranging across all topics in nutrition, including sports nutrition. There are entries on various diets, past and present.

This book is intended as a tool for architects, interior designers and other professionals to identify the space requirements for domestic or commercial kitchens and food preparation areas.

During the years 1987 and 1988 we published a series of articles on the molding of thermoplastics materials in the magazine British Plastics and Rubber (B P & R).

Created by the Joint Photographic Experts Group (JPEG), the JPEG is the first colour still image data compression international standard. It consists of 20 explicitly defined processes to encode or decode continuous tone still images.

Fundamentals of Dairy Chemistry has always been a reference text which has attempted to provide a complete treatise on the chemistry of milk and the relevant research.

Packaging is an essential feature of modern life. The science and art of packaging is so vast that no single book or even a multivolume work could hope to cover the entire scope of topics, from Artwork to Zipper.

The annual cost of medical care in the U niled States is rapidly approaching a trillion dollars. Incineration technology has largely been developed for disposing mu nicipal solid waste (MSW) and hazardous waste (HW).

Volume II covers antenna theory and design, describing a number of antenna types, including receiving, wire and loop, horn, frequency-independent, microstrip, refelector, and lens antennas. This section also includes arrays, providing array theory as well as exploring waveguide-fed slot arrays, peiodic arrays, and aperiodic arrays.

This book was written with a dual purpose, as a reference book for practicing engineers and as a textbook for students of prestressed concrete.

Provides an introduction to general field work through selected topics that illustrate specific techniques and methodologies. This book includes one hundred and twenty-three main entries that deal with aspects of exploration surveys, geotechnical engineering, environmental management, field techniques, mapping, prospecting, and mining.

Written by experts in the field and filled with the latest research data, this comprehensive work presents important information on the nutritional properties of fish oils for human health and the analysis of fatty acids.

Environmental legislation is relatively new as an independent field of the law: the laws themselves are primarily a conglomeration of older legal doctrines from other fields of law, modified and adapted for particular situations (Landau and Rheingold 1971).

As the electronics industry continues to pro vide products that operate faster than their predecessors in a smaller space with a reduced cost per function, the role of electronic packaging technology will assume an even greater role in the development of cost-effective products.

Soils and Foundations for Architects and Engineers provides in-depth, yet simplified, information on the more commonly encountered aspects of soils mechanics and foundations.

Far from being the passive containers for semiconductor devices of the past, the packages in today's high performance computers pose numerous challenges in interconnecting, powering, cooling and protecting devices.

In addition, new bioprocessing practices arising from the exciting recent advances in biotech nology, including innovative fermentation cell culture and enzyme based operations, are rapidly extending the frontiers of bioprocessing.

These advantages have been recognized for precast concrete raft pavement units (raft units) since their introduction in the 1930s.

The rapid development of electronics and its engineering applications ensures that new topics are always competing for a place in university and polytechnic courses. vii Preface The basic principles of radar do not change, but the design and technology of practical radar systems have developed rapidly in recent years.

In view of rapidly advancing technology and an appreciation for the systems approach in industry and agriculture, this third book has been restructured to provide the student and practitioner with an integrated concept of pork production.
