Описание: In 2%-7% of all bone fractures, union is delayed or fails. Nonunions of the bones represent a challenge for orthopedic surgeons and can have a severe psychological impact on these patients. Moreover, the social cost of managing these lesions, often requiring multiple procedures, may be very high, and complications related to improper treatment are not rare. This text is based on the development over many years of the devices and operative techniques of monofocal, bifocal, and multifocal compression-distraction osteosynthesis, in cooperation with the CITO Institute of Moscow and the LNIITO Institute of Riga, and on hundreds of operative procedures on noninfected and infected nonunions personally performed by the authors both in the former Soviet Union, Russia and Italy. The primary purpose of this book is to discuss currently available tools for diagnosing long bone nonunions, to illustrate the means of prevention, and to specify the indications for management using compression-distraction techniques.
This book introduces two of the most exciting heat pumping technologies, the coabsorbent and the thermal recovery (mechanical vapor) compression, characterized by a high potential in primary energy savings and environmental protection. New cycles with potential applications of nontruncated, truncated, hybrid truncated, and multi-effect coabsorbent types are introduced in this work.
Thermal-to-work recovery compression (TWRC) is the first of two particular methods explored here, including how superheat is converted into work, which diminishes the compressor work input. In the second method, thermal-to-thermal recovery compression (TTRC), the superheat is converted into useful cooling and/or heating, and added to the cycle output effect via the coabsorbent technology. These and other methods of discharge gas superheat recovery are analyzed for single-, two-, three-, and multi-stage compression cooling and heating, ammonia and ammonia-water cycles, and the effectiveness results are given.
The author presents absorption-related topics, including the divided-device method for mass and heat transfer analysis, and truncation as a unique method for a better source-task match. Along with advanced gax recovery, the first and second principles of COP and exergy calculation, the ideal point approaching (i.p.a.) effect and the two-point theory of mass and heat transfer, the book also addresses the new wording of the Laplace equation, the Marangoni effect true explanation, and the new mass and heat exchangers based on this effect.
The work goes on to explore coabsorbent separate and combined cooling, heating, and power (CHP) production and advanced water-lithium bromide cycle air-conditioning, as well as analyzing high-efficiency ammonia-water heat-driven heating and industrial low-temperature cooling, in detail.
Readers will learn how coabsorbent technology is based on classic absorption, but is more general. It is capable of offering effective solutions for all cooling and heating applications (industry, agriculture, district, household, etc.), provided that two supplying heat-sink sources with temperatures outdistanced by a minimum of 12-15 C are available. This book has clear and concise presentation and illustrates the theory and applications with diagrams, tables, and flowcharts.

Описание: Still Image Compression on Parallel Computer Architectures investigates the application of parallel-processing techniques to digital image compression. Digital image compression is used to reduce the number of bits required to store an image in computer memory and/or transmit it over a communication link.
