Arburg practical guide to injection moulding / par Goodship,, V. Publication : [S.l.] : Smithers Rapra Press, 2004 . 276 p. ; , This Practical Guide to Injection Moulding is based on course material used by ARBURG in training operators of injection moulding machines. It comes from many years of experience in this field and has been edited by an expert injection moulder at Warwick University. It will be of use to experts looking to fill gaps in their knowledge base and to those new to the industry. The factors involved in injection moulding, from material properties and selection to troubleshooting faults, are all examined in this book. It covers the equipment types in use and machine settings for different types of plastics. Material flow is critical in moulding and there are sections covering rheology and viscosity. High temperature can lead to poor quality mouldings due to material degradation and this is discussed. There are an exceptional number of figures in this text, with many photographs of machinery and mouldings to illustrate key points. There are also numerous tables listing key properties and processing parameters. Flow charts are included in the chapter on troubleshooting to indicate what can be changed to resolve common problems. Injection moulding in the Western World is becoming increasingly competitive as the manufacturing base for many plastics materials has moved to the East. Thus Western manufacturers have moved into more technically difficult products and mouldings to provide more added value and maintain market share. Technology is becoming more critical, together with innovation and quality control. There is a chapter on advanced processing in injection moulding covering multi-material and assisted moulding technologies. This Guide will assist progress in developing good technical skills and appropriate processing techniques for the range of plastics and products in the marketplace. 30 cm.

Archaeological chemistry / par Pollard,, A. Mark. Publication : [S.l.] : Royal Society of Chemistry, 1996 . 392 p. ; , The application of chemistry within archaeology is an important and fascinating area. It allows the archaeologist to answer such questions as "what is this artefact made of?", "where did it come from?" and "how has it been changed through burial in the ground?", providing pointers to the earliest history of mankind. Archaeological Chemistry begins with a brief description of the goals and history of archaeological science, and the place of chemistry within it. It sets out the most widely used analytical techniques in archaeology and compares them in the light of relevant applications. The book includes an analysis of several specific archaeological investigations in which chemistry has been employed in tracing the origins of or in preserving artefacts. The choice of these investigations conforms to themes based on analytical techniques, and includes chapters on obsidian, ceramics, glass, metals and resins. Finally, it suggests a future role for chemical and biochemical applications in archaeology. Archaeological Chemistry enables scientists to tackle the fundamental issues of chemical change in the archaeological materials, in order to advance the study of the past. It will prove an essential companion to students in archaeological science and chemistry, field and museum archaeologists, and all those involved in conserving human artefacts. 22 cm.

Atomic physics : an exploration through problems and solutions / par Budker, Dmitry. Publication : [S.l.] : Oxford University Press, USA, 2004 . 456 p. ; , This book is intended for advanced undergraduate, graduate students and researchers who are interested in Atomic, Molecular and Optical (AMO) Physics. Written as a collection of problems, hints and solutions, the book will provide help in learning about both fundamental and applied aspects of this vast field of knowledge, where rapid and exciting developments are currently taking place. The authors tough upon a broad spectrum of phenomena and techniques and adopt an experimentalist's approach, by avoiding formal calculations whenever possible in favor of "back-of-the-envelope" estimates, symmetry arguments and physical analogies. While complete coverage of all AMO Physics is not attempted, there are chapters on atomic structure, behavior of atoms and molecules in external electromagnetic fields, atomic collisions and experimental techniques. Special attention is given to a discussion of ideas and experimental methods in several "hot areas", a few of these being cold atoms and Bose-Einstein condensates, tests of fundamental symmetries, atomic magnetometers and frequency comb metrology with ultra-short laser pulses. 24 cm.

Binding and dissociation kinetics for different biosensor applications using fractals par Sadana, Ajit. Publication : [S.l.] Elsevier Science 2006 . 384 p. , The application of biosensors is expanding in different areas. These are portable and convenient devices that permit the rapid, accurate, and reliable detection of analytes of interest present either in the atmosphere or in aqueous or in liquid phases. The detection of glucose levels in blood for the effective management of diabetes is one. Though different biosensors have been designed for an increasing number of applications, the kinetics of binding (and dissociation) of analytes by the receptors on the biosensor surfaces has not been given enough attention in the open literature. This is a very important area of investigation since it significantly impacts biosensor performance parameters such as stability, sensitivity, selectivity, response time, regenerability, etc. Binding and Dissociation Kinetics for Different Biosensor Applications Using Fractals addresses this critical need besides helping to correct or demonstrate the need to modify the present software available with commercial biosensors that determines the kinetics of analyte-receptor reactions on biosensor surfaces. * first book to provide detailed kinetic analysis of the binding and dissociation reactions that are occuring on the biosensor surface * addresses the area of analyte-receptor binding and dissociation kinetics occurring on biosensor surfaces * provides physical insights into reactions occuring on biosensor surfaces. 24 cm.

Biofuels and bioenergy : processes and technologies / par Lee, Sunggyu. Publication : Boca Raton, FL : Taylor and Francis , 2012 . xvii, 323 pages : , "Preface Humans have a long history of using a wide variety of biomass resources as sources of energy and fuel. The discovery and use of fossil energy, represented largely by coal, natural gas, and petroleum, have drastically reduced the utilization of biomass fuels. The technologies of generating electricity using biomass, producing bioliquid fuels, and powering motor vehicles using bioalcohols and blended gasolines have been developed and practiced since the early twentieth century. Up until recently, however, development interest in biofuels had lessened due to the availability of relatively inexpensive fossil energy resources as well as the handling and transportation convenience of these conventional fuel sources. Due to the strong growth of global transportation fuel demand, sharply escalating worldwide fossil energy prices, fear over the dwindling supply of petroleum and natural gas for the near future, and credible evidence linking global warming and climate change issues with the emission of greenhouse gases, global interest and R&D efforts in renewable alternative fuels have become intense and fiercely competitive, targeting both short- and long-term solutions to alternative energy needs. Although there are a number of options and routes for energy sustainability and independence via renewable alternative energy, bioenergy and biofuels certainly possess outstanding potential to provide solutions and relief to many of the immediate, intermediate, and long-term societal needs of clean energy and their associated challenges"-- 25 cm.

Biotransformations in organic chemistry : a textbook / par Faber, Kurt. Publication : [S.l.] : Springer, 2004 . 454 p. ; , The use of biocatalysts, employed either as isolated enzymes or whole microbial cells, offers a remarkable arsenal of highly selective transformations for state-of-the-art synthetic organic chemistry. Over the last two decades, this methodology has become an indispensable tool for asymmetric synthesis, not only at the academic level, but also on an industrial scale. This well-established textbook on biocatalysis provides a basis for undergraduate and graduate courses in modern organic chemistry, as well as a condensed introduction into this field. After a basic introduction into the use of biocatalysts ? principles of stereoselective transformations, kinetics and enzyme properties ? the different types of reactions are explained according to the 'reaction principle', such as hydrolysis, reduction, oxidation, C-C bond formation, etc. Special techniques, such as the use of enzymes in organic solvents, immobilization techniques and the use of modified enzymes, are treated in a separate section. A final chapter deals with the basic rules for the safe and practical handling of biocatalysts. In this revised and corrected 5th edition, emphasis has been given to an improved didactic style in order to facilitate a deeper understanding of the underlying principles. New developments, such as dynamic resolution, stereo-inversion and enantio-convergent processes are included. 23 cm.
