The second English-language edition of the Small Fragment Set Manual was enthusiastically received and quickly went into a second printing. In preparing a third edition, we found it necessary to revise the text extensively and partly restructure it. The reasons for this are numerous. Experience of recent years has brought technical refinements in the operative treatment of many types of small fracture. Many of these changes stem from the small-fragment-set training programs conducted in Switzerland since 1980, and also from courses and symposia that have been held in other European countries and the United States. These events were occasions for a fruitful ex change of experience with surgeons who were critical of our methods. As a result of this exchange, we perceived a need both to revise our indications and to give greater attention to alternative techniques. We also felt it necessary to respond to criticisms of the first two editions concerning the catalog-like instrument lists and illustrations, and the attention given to fundamental techniques. Many surgeons who work or would like to work with small implants, especially those practicing abroad, are inexperienced in operations on the larger bones. It is imperative that these colleagues be given a basic introduction to the "biomechanical thinking" of the Swiss Association for the Study of Internal Fixation (ASIF).
This book focuses on common types of polymers belonging to the class of water soluble polymers. It covers a wide range of applications: food, cosmetic, medical, lithography and ink jet printing, agricultural, wastewater cleaning, and oilfield. The text is arranged according to the chemical constitution of polymers and reviews the developments that have taken place in the last decade. Each chapter follows the same template. A brief introduction to the polymer type is given and previous monographs and reviews dealing with the topic are listed for quick reference. The text continues with monomers, polymerization, fabrication techniques, properties, applications, as well as safety issues. Providing a rather encyclopedic approach to water soluble polymers, the Handbook of Engineering and Specialty Thermoplastics: Presents a listing of suppliers and commercial grades Reviews current patent literature, essential for the engineer developing new products Contains an extensive tradenames index with information that is fairly unique Concludes with an index of acronyms and a general index The Handbook of Engineering and Specialty Thermoplastics: Water Soluble Polymers provides a comprehensive reference for chemical engineers and offers advanced students a textbook for use in courses on chemically biased plastics technology and polymer science.
This book presents the state-of-the-art polymerization, fabrication and application methods of high performance industrial polymers, pertaining specifically to recent developments from the chemistry and engineering perspective. All introductory, monomer, polymerization and fabrication techniques are reviewed, and basic information is provided to help demystify the more advanced material. Chapters are arranged according to chemical constitution of the individual classes, starting with main chain carbon-carbon polymers and leading to ether-containing, sulphur-containing, and so on. Special additives, suppliers and commercial grades, safety, environmental impact and recycling are also explained. Commercially available polymers are listed throughout the book. - Presents the state-of-the-art polymerization, fabrication and application methods of high performance industrial polymers - Provides fundamental information for practical engineers working in industries that develop advanced applications (electronic industry, medical instruments, etc) - Discusses environmental impact and recycling of particular polymers - Includes recent journal and patent literature of specific interest to specialists
During the last decades completely new technologies for high speed railway vehicles have been developed. The primary goals have been to increase traction, axle load, and travelling speed, and to guarantee safety of the passengers. However, the new developments have revealed new limitations: settlement and destruction of the ballast and the subgrade lead to deterioration of the track; irregular wear of the wheels cause an increase in overall load and deterioration of passengers comfort; damage of the running surfaces of the rail and the wheel becomes more frequent. This problems have been investigated in the Priority Programme SPP 1015 supported by the Deutsche Forschungsgemeinschaft (DFG), aiming at a better understanding of the dynamic interaction of vehicle and track and the long-term behaviour of the components of the system. The book contains the scientific results of the programme as presented at the concluding colloquium held at University of Stuttgart, Germany, March 13-15, 2002.
