CO2 Laser Cutting explains and describes how engineering materials are cut using a CO2 laser. Information is given on the cutting of metals and non metals on a wide range of levels from practical advice and processing parameters to explanations of the physical and chemical reactions which take place in the cut zone. In an effort to make the book as readable and informative as possible the subject is treated in a descriptive rather than a mathematical way. The benefit of CO2 Laser Cutting is twofold as it gives practical advice to the operator and technical advice to the researchers or scientist.

The laser has given manufacturing industry a new tool. When the laser beam is focused it can generate one of the world's most intense energy sources, more intense than flames and arcs, though similar to an electron beam. In fact the intensity is such that it can vaporise most known materials. The laser material processing industry has been growing swiftly as the quality, speed and new manufacturing possibilities become better understood. In the fore of these new technologies is the process of laser cutting. Laser cutting leads because it is a direct process substitu tion and the laser can usually do the job with greater flexibility, speed and quality than its competitors. However, to achieve these high speeds with high quality con siderable know how and experience is required. This information is usually carefully guarded by the businesses concerned and has to be gained by hard experience and technical understanding. Yet in this book John Powell explains in lucid and almost non technical language many of these process wrinkles concerning alignment, cornering, pulsing, water jets, material properties, cutting speeds as well as tricks with surface coating and much much more. It is a book which managers and technicians in laser job shops and laser processing facilities would be foolish not to read.

During the past two decades, higher processing temperatures, more efficient engines at higher temperatures, and the use of a vacuum environment have led to the development of a number of important processing, fabrication, and industrial techniques, resulting in new material forms including: matrix composites, nano- and functionally graded structures, plastics, smart piezoelectric materials, shape memory alloys, intermetallics, ceramics, and fullerenes. The second edition of this encyclopedia covers the new materials that have been invented or modified in recent years and updates information on basic materials as well. Encyclopedia of Materials, Parts, and Finishes, Second Edition brings together in one concise volume the most up-to-date information on materials, forms and parts, finishes, and processes utilized in the industry. There is not a handbook currently on the market that incorporates as much materials information in one volume. The coverage of materials usage extends from the breadth of military and aerospace materials to commercial (aircraft, automotive, electronics) and basic materials (wood, rubber, etc.). Each entry provides thorough, straightforward definitions along with examples of corresponding materials, parts, or finishes. Like its predecessor, this encyclopedia will be an invaluable reference that belongs on the desk of every materials scientist and engineer.

This is the second edition of the text "Bioreaction Engineering Principles" by Jens Nielsen and John Villadsen, originally published in 1994 by Plenum Press (now part of Kluwer). Time runs fast in Biotechnology, and when Kluwer Plenum stopped reprinting the first edition and asked us to make a second, revised edition we happily accepted. A text on bioreactions written in the early 1990's will not reflect the enormous development of experimental as well as theoretical aspects of cellular reactions during the past decade. In the preface to the first edition we admitted to be newcomers in the field. One of us (JV) has had 10 more years of job training in biotechnology, and the younger author (IN) has now received international recognition for his work with the hottest topics of "modem" biotechnology. Furthermore we are happy to have induced Gunnar Liden, professor of chemical reaction engineering at our sister university in Lund, Sweden to join us as co-author of the second edition. His contribution, especially on the chemical engineering aspects of "real" bioreactors has been of the greatest value. Chapter 8 of the present edition is largely unchanged from the first edition. We wish to thank professor Martin Hjortso from LSU for his substantial help with this chapter.

This book, first published in 2005, provides students and practising glaciologists with the tools they need to understand modern glaciology. Relatively simple concepts are introduced first, followed by mathematically more sophisticated chapters. A knowledge of basic calculus is assumed, but important concepts of physical processes are developed from elementary principles. Emphasis is placed on connections between modern research in glaciology and the origin of features of glacial landscapes. Student exercises are included. This new edition builds on the successful first edition: it has been completely updated, and important new sections and whole chapters have been added. Principles of Glacier Mechanics is designed to be used as a primary textbook in upper division and graduate courses in glaciology, and can be used as either a primary or supplementary text in courses in glacial geology. Practising glacial geologists and glaciologists will also find it useful as a reference book.
