This book deals with the new and now-expanding field of friction, wear, and other surface-related mechanical phenomena for polymers. Polymers have been used in various forms such as bulk, films, and composites in applications where their friction, wear resistance, and other surface-related properties have been effectively utilized. There are also many examples in which polymers have performed extremely well, such as in tyres, shoes, brakes, gears, bearings, small moving parts in electronics and MEMS, cosmetics/hair products, and artificial human joints. Around the world, much research is currently being undertaken to develop new polymers, in different forms, for further enhancing tribological performance and for finding novel applications. Keeping in view the importance of tribology of polymers for research and technology as well as the vast literature that is now available in research papers and review articles, this timely book brings together a wealth of research data for an understanding of the basic principles of the subject.

Small Animal Diagnostic Ultrasound outlines the basic physical principles of ultrasound, as well as imaging artifacts and the use of ultrasonography, in a logical body-systems approach. This second edition is completely revised and up-to-date, detailing current developments in ultrasonography. Two completely new chapters on thoracic and musculoskeletal ultrasound, as well as revised coverage of cardiology, CT/MR, and the reproductive system make this edition even more useful and clinically relevant. Full-color illustrations and color Doppler images of abdominal organs enhance and clarify discussions in the text.
