In the powder metallurgical process, diamond material composites are produced by pressing and sintering of a mixture, consisting of diamond and metal powder like cobalt. Due to the high hardness of diamond, the surface of press die is easily damaged. To increase the life time of press dies, thin layers, deposited by PVD, has been employed. First, the standard tests, such as scratch test and pin-on-disc, were performed in order to characterize the adhesion and the tribology of the coatings. The r...

Flood based irrigation in particular spate irrigation relies on variable flood scenarios occurring every year. Management of spate flood for spate irrigation must cope with the variability and uncertainty of water supply. Coping with water supply risks is often the only way to harness the opportunities for a productive use of water in arid environment. Integrating and strengthening community responses into irrigation policies and improvement plans could ensure sustainable and productive spate ir...

Management of sludge is one of the most pressing issues in sanitation provision. The situation is especially complex when large quantities of fresh sludge containing various contaminants are generated in onsite sanitation systems in urban slums, emergency settlements and wastewater treatment facilities that require proper disposal of the sludge. The application of fast and efficient sludge management methods is important under these conditions. This study focused on the development of an innova...

Small Signal Audio Design is a highly practical handbook providing an extensive repertoire of circuits that can be assembled to make almost any type of audio system. The publication of Electronics for Vinyl has freed up space for new material, (though this book still contains a lot on moving-magnet and moving-coil electronics) and this fully revised third edition offers wholly new chapters on tape machines, guitar electronics, and variable-gain amplifiers, plus much more. A major theme is the us...

The Workplace Walk-Through is the first volume in a series dedicated to providing physicians with more advanced tools for performing not only the routine tasks involved in occupational medicine, but also the most unusual and challenging assignments.

The 4th edition of the handbook Refractory Materials has been completely revised and expanded. It also appears in a new format (A5) with pictures (four colors) and e-book (disc). The reader obtains an extensive and detailed overview focusing on design, properties, calculations, terminology and testing of refractory materials thus providing important information for daily work. In the new edition of this standard work several chapters were revised with the assistance of new authors. The appendix...

Process Technology provides a general overview about chemical and biochemical process technology. It focuses on the structure and development of production processes, main technological operations and the important aspects of process economics. The theoretical foundations in each chapter are supplemented by case studies and examples in a clear and instructive manner to illustrate the practical aspects. The author highlights operating principles, reasons for application and available industrial e...

For decades, science and technology (sci-tech) have influenced world trade, world economy, and international finance. However, their specific impacts are seldom known and related empirical studies are rare. Thus, we must quantify and empirically explore how sci-tech influences such areas as mentioned above. The purpose of this book is to explore how sci-tech influences world trade, foreign exchange, and currency internationalization in various ways through quantifying science & technology first....

The series of International Symposiums on Mining with Backfill explores both the theoretical and practical aspects of the application of mine fill, with many case studies from both underground and open-pit mines. Minefill attendees and the Proceedings book audience include mining practitioners, engineering students, operating and regulatory professionals, consultants, academics, researchers, and interested individuals and groups.The papers presented at Minefill symposiums regularly offer the nov...

The author presents single screw extrusion technology together with the relevant polymer fundamentals, with an emphasis on screw design. The presentation begins on a physical level, providing an in-depth conceptual understanding, followed by an analytical level with mathematical models. Practical applications of the mathematical models are illustrated by numerous examples. A brief description of twin screw extrusion technology is also presented. The second edition includes new chapters on die d...

The selection of the proper materials for a structural component is a critical activity that is governed by many, often conflicting factors. Incorporating materials expert systems into CAD/CAM operations could assist designers by suggesting potential manufacturing processes for particular products to facilitate concurrent engineering, recommending various materials for a specific part based on a given set of characteristics, or proposing possible modifications of a design if suitable materials f...

Originally published in 1993, over 16,000 tradename surface-active agents for industrial applications, manufactured worldwide, are contained in this edition. General-use surfactants, such as emulsifiers, wetting agents, foaming agents, detergents, dispersants, and solubilizers are included, as well as detergent raw materials, defoamers, and antifoaming agents. The types and quantities of surfactants available commercially are numerous and the difficulty in making choices between products may be...
