Abstract: "This book is an edited collection of papers by leading experts on the population genetics and evolutionary biology of malaria, a disease which results in three million deaths each year in the world. ""Malaria Hypothesis"" refers to the hypothesis, which was proposed by J.B.S. Haldane at the 8th International Congress of Genetics in Stockholm in 1948, that the identical geographic distribution of both falciparum malaria and thalassemia in the mediterranean region suggests that the heterozygous individuals for thalassemia (or microcythemia as it was called then) might have greater resistance to malarial infection. Haldane, later in the same year, expanded his theory to infectious disease in general at another international conference, at Pallanza in Italy. Haldane's hypothesis was subsequently confirmed in the African populations by A.C. Allison and later by others during the last fifty years, although at first for sickle cell anemia and later for thalassemia with varying degrees of success. The malaria hypothesis still remains today a unique example of that kind of balanced polymorphism, not only in genetics but in all of biology. It opened up new insights into our perspective of the genetics and population dynamics of disease prevalence, particularly infectious disease."

Abstract: Masters Theses in the Pure and Applied Sciences was first conceived, published, and dis­ seminated by the Center for lnformation and Numerica/ Data Analysis and Synthesis (C/NDAS) * at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the ac­ tivity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficia! to the academic and general scientific and technical community. After fi ve years of this joint undertaking we had concluded that it was in the interest of ali concerned if the printing and distribution of the volume were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and App/ied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. Ali back issues can also be ordered from Plenum. We have reported in Volume 21 (thesis year 1976) a total of 10,586 theses titles from 25 Canadian and 219 United States universities. We are sure that this broader base for theses titles reported will greatly enhance the value of this important annual reference work.

Abstract: 3 nant expression systems have been used to make MHC molecules con­ taining a single peptide of interest. To date, fifteen single peptide class I structures (incorporating three different HLA and two different H-2 allotypes/isotypes) and four additional class II structures (two single peptide complexes and two superantigen complexes) have been reported. These advances have enabled us to study the atomic detail of antigen presentation and the general mechanisms behind peptide binding, and begin to construct models of T cell recognition. Another area of research which has exploded over the past five years has been the identification of MHC-associated peptides. There are several methods one can use to determine the sequence identity of MHC restricted peptides. Historically, the most successful technique, albeit crude and encumbered with serious limitations, has been the use of overlapping synthetic peptides and T cell clones. Unfortunately, this method absolutely requires: (i) knowledge of the target antigen; (ii) availability of T cell clones; and (iii) a relatively short overall length for the target source protein, such that a set of overlapping pep tides can be affordably synthesized. Briefly, the entire sequence of the tar­ get protein is chemically synthesized using overlapping peptides which are then screened for biological activity using standard T cell presen­ tation assays. Despite its limitations, this method was used to identify the first immunodominant epitopes reported in the literature and con­ tinues to be used successfully today.

Abstract: The field of "Oxygen Activation" has attracted considerable interest recently, not only because it presents challenges in those fields of basic research that aim to understand the fundamental aspects of chemical and biological reactions that involve dioxygen, but also because of its wide range of practical implications in such diverse fields as medicine, synthesis of pharmaceuticals and other organic compounds, materials science, and atmospheric science. This is the second of two volumes that focus on the subject of oxygen activation, the first slanted toward chemistry and the second toward biological chemistry. We planned these volumes to be more general than many monographs of this sort, not as detailed summaries of the authors' own research but rather as general overviews of the field. Our choice of topics was strongly influenced by our syllabus for a course entitled "Oxygen Chemistry," which two of us have twice taught jointly at UCLA. Definition of important issues, horizons, and future prospects was an important goal, and, although totally comprehensive coverage was not possible, we believe that we have chosen a representative selection of research topics current to the field. We have targeted this work to a diverse audience ranging from professionals in fields from physics to medicine to beginning graduate students who are interested in rapidly acquiring the basics of this field.

Abstract: The present collection is devoted to algorithmic methods, and computer algorithms, for the synthesis of digital computers and controlling machines. The work reported in the papers collected here was performed at the Institute for Prob­ lems of Information Transmission of the Academy of Science of the USSR, in the section for computational techniques of the Institute of Mathematics of the Siberian Division of the Academy of Science of the USSR, and in the Problem Laboratory of Computing Devices of the Siberian Physics -Engineering Ins titute. The paper by A. D. Zakrevskii is devoted to the discussion of ways of solving basic prob­ lems in the area of computer solution of logical problems, including the problem of automata synthesis. In the paper by E. I. Piil' a methodology is presented for coding internal states and input states of finite automata which is suitable for computer realization. The suggested coding al­ gorithms permit one to take account simultaneously of constraints on inadmissible critical races of memory elements, speed and simplicity of structure of the automaton's logical transformer. E. N. Turuta's paper investigates certain methods of synthesizing reliable automata, based on the introduction of redundancy into the automaton's memory block. The paper by Ya. I. Fet contains a solution to the problem of synthesizing schemes of minimal depth for one of the most widely used bases of elements in computer technology.

Abstract: The great majority of papers on brain research that have been published in Mainland China in recent years have appeared in the Chinese language (only a small fraction of the work has appeared in English in the journal Scientia Sinica), and hence they have remained inacces­ sible to other workers, since there have been no translation programs of publications in this field in Chinese of the types that have existed, for example, for Russian-language materials. Accordingly, most investigators are not aware of the work of their Chinese colleagues in this field. Yet the field has been an active if small one in China, and has covered a variety of topics that include electrophysiology, neurochemistry, neuropharmacology, neuropsychology, and in­ strumentation. Standard techniques and instruments, a number of Chinese manufacture, have been employed. Moreover, Chinese workers have been quite familiar with the publications of other investigators, as is readily apparent from the bibliographies of the papers (see Index).

Abstract: The mathematical theory of wave propagation along a conductor with an external coaxial return is very old, going back to the work of Rayleigh, Heaviside, and J. J. Thomson. These words were written by S. A. Schelkunoff back in 1934. Indeed, those early works dealt with signal propagation along the line as well as electromagnetic shielding of the environment inside and/or outside the metallic enclosures. Max­ well himself developed pioneering studies of single-layer shielding shells, while a paper with such a "modern" title as "On the Magnetic Shielding of Concentric Spherical Shells" was presented by A. W Rucker as early as 1893! * Such "state of the art" shielding theory created in the last century is even more amazing if you think that at almost the same time (namely, in 1860s), a manuscript of Jules Verne's book, Paris in the. xx Century, was rejected by a publisher because it pre­ dicted such "outrageously incredible" electrotechnology as, for example, FAX service by wires and the electrocutioner's chair. (With regard to the last invention, I suspect many readers would rather Jules Verne has been wrong. ) However, although the beginning of electromagnetic shielding theory and its implementation to electronic cables date back more than a century, this dynamic field keeps constantly growing, driven by practical applications.

Abstract: are often lined with garages in front of houses that are clearly more internalized in design, some even taking on a fortress-like appearance. Today's new homes are technically superior in construction; i.e., they are more energy efficient, weather resistant and maintenance free. However, they also seem to lack the warmth and charm of prewar homes, for which more construction dollars were spent on quality veneers, buUt-in features and other human-scale details. The postwar need for massive amounts of "affordable" housing for returning GIs helped to encourage buUding practices that could reduce on-site labor and material costs in houses. The accommodation of the automobile, cost-cutting movements and a variety of other trends caused a gradual decline in the human, social and emotional qualities of postwar residential architecture. This book will attempt to look at the issues and choices facing today's residential designers and home buUders and ask: How can we make our new houses and neighborhoods more responsive to humanistic needs, partlcularly in light of constant pressures to keep housing costs down? This question will generally be addressed by comparing historical designs to those of today, to see if we might be able to reconsider some "old-fashioned" ideas in new housing designs.

Abstract: We define biomagnetism broadly as the science of processes and functions in living organisms induced by static magnetic fields. Biomagnetic research has greatly increased since the publication of the first volume of this series. While much of this work has been reported in various international journals, there exists a need for this work to be collected together in one place. This book covers a rather wide area of research, both with respect to the strength of the field, ranging from "zero" to 150,000 oersteds, and with respect to the various specimens and their biological functions. It is designed primarly to help clarify the action of magnetic fields on biological systems with the hope of achieving a better understanding of the fundamental physiological processes occurring in them. In some chapters it is suggested that magnetic fields could ultimately be used in the treatment of disease. I would like to take this occasion to thank the contributors for their generous interest and willing cooperation. M. F. B. June 1969 Chicago, Illinois v CONTRIBUTORS Robert A.

Abstract: During the translation, the author had the opportunity to re­ view several chapters, taking into consideration the more recent literature. As far as possible all new theoretical concepts and experi­ mental data published before 1963 have been quoted and discussed under the theoretical viewpoint of this book. A new chapter "Passivity and Inhibition During High-Tempera­ ture Oxidation" was introduced. Section 4.8 was enlarged by a dis­ cussion of the transition from internal to external oxidation. The author very much appreciates the cooperation of the trans­ lator and of Plenum Press. Gottingen, April 1.965 Karl Hauffe v Preface The number of publications concerned with oxidation and cor­ rosion processes has become so copious that many engineers and scientists find it practically impossible to obtain an overall view of the growing body of knowledge and to bring order to the confusing multiplicity of experimental data. As a result the need for a compre­ hensive survey of the present state of research in this field has be­ come more and more urgent.

Abstract: The necessity of prediction and fine control in the food manufacturing process is becoming more important than ever before, and food researchers and engineers must confront difficulties arising from the specificity of food materials and the sensitivity of human beings to taste. Fortunately, an overview of world research reveals that the mechanisms of the many complex phenomena found in the food manufacturing process have been gradually elucidated by skilful experiments using new analytical tools, methods and theoretical analyses. This book, the proceedings of the 6th International Congress on Engineering and Food (ICEF6), held for the first time in Asia - in Chiba, Japan May 23 -27, 1993 - summarizes the frontiers of world food engineering in 1993. Congress was joined by the 4th International Conference on Fouling and Cleaning. There were 476 active members from 31 countries participating in the Congress. The editors hope that readers will find this book to be a useful review of the current state of food engineering, and will consider future developments in this research field. The editors extend thanks to the members of the organizing committee of ICEF6, and the advisors, Dr. Ryozo Toei, Professor Emeritus of Kyoto University and Dr. Masao Fujimaki, Professor Emeritus of the University of Tokyo. They also acknowledge the international advisory board members who helped the organizing committee in many ways, and the 10 foundations and 66 companies that financially supported the ICEF6. Finally, the editors are indebted to the reviewers of the manuscripts of these proceedings.

Abstract: The use oflubricants began in ancient times and has developed into a major international business through the need to lubricate machines of increasing complexity. The impetus for lubricant development has arisen from need, so lubricatingpractice has precededan understandingofthescientificprinciples. This is not surprising as the scientific basis of the technology is, by nature, highly complex and interdisciplinary. However, we believe that the under­ standing of lubricant phenomena will continue to be developed at a mol­ ecular level to meet future challenges. These challenges will include the control of emissions from internal combustion engines, the reduction of friction and wear in machinery, and continuing improvements to lubricant performanceand life-time. More recently, there has been an increased understanding ofthe chemical aspects of lubrication, which has complemented the knowledge and under­ standing gained through studies dealing with physics and engineering. This book aims to bring together this chemical information and present it in a practical way. It is written by chemists who are authorities in the various specialisations within the lubricating industry, and is intended to be of interest to chemists who may already be working in the lubricating industry or in academia, and who are seeking a chemist's view of lubrication. It will also be of benefit to engineers and technologists familiar with the industry who requirea more fundamental understanding oflubricants.

Abstract: The Just-in-time (JIT) manufacturing system is an internal system in use by its founder, Toyota Motor Corporation, but it has taken on a new look. Toyota Production System, Second Edition systematically describes the changes that have occurred to the most efficient production system in use today. Since the publication of the first edition of this book in 1983, Toyota has integrated JIT with computer integrated manufacturing technology and a strategic informa­ tion system. The JIT goal of producing the necessary items in the necessary quantity at the necessary time is an internal driver of production and operations management. The addition of computer integrated technology (including expert systems by artificial intelligence) and information systems technology serve to further reduce costs, increase quality, and improve lead time. The new Toyota production system considers how to adapt production schedules to the demand changes in the marketplace while satisfying the goals of low cost, high quality, and timely delivery. The first edition of this book, Toyota Production System, published in 1983, is the basis for this book. It was translated into many languages including Spanish, Russian, Italian, Japanese, etc., and has played a definite role in inspiring production management systems throughout the world.

Abstract: It is now more than twenty years since a proposal was first mooted to hold an international tunnelling symposium in Britain. At the time of the first symposium, held in London in 1976, the Channel Tunnel pro­ ject had just been shelved. Last weekend a charity walk was held in the finished tunnel, which will be open for business later in the year. Tunnels have figured prominently, and at times spectacularly, in the development of national and international links and it is hoped that such links gather pace in the future. It is particularly pleasing that Alastair Biggart of Storebrelt has agreed to deliver the twenty-sixth Sir Julius Wernher Memorial Lecture of the Institution of Mining and Metallurgy, entitled 'The changing face of tunnelling', at the start of this event. * Although almost every edition of the technical journals on tunnelling reports another £1 billion scheme somewhere in the world, it would be unfair of me to suggest that tunnelling is restricted to these prestigious schemes for major transport links. Much of the work that makes mod­ ern life possible receives hardly a mention outside the technical press and one suspects that society at large applies the 'out of sight, out of mind' attitude even more readily to underground construction than it does to other forms of engineering. Clearly, there is a contiiming need to improve the capacity and performance of our infrastructure, while hav­ ing a careful regard for the environment.

Abstract: This book attempts to explain the scientific basis for UHT sterilization and aseptic filling, as well as describe the processes and equipment used. I have tried to avoid producing merely a catalogue of sterilizers and aseptic fillers. Instead I have attempted to explain the principles on which the different types of plant operate, and discuss the factors which influence performance, so that information given by manufac­ turers may be assessed by readers in relation to their own processing requirements. Statements are generally supported by references. Where no re­ ference is given, personal experience or my interpretation of the work of others is my justification. Although the book deals mainly with milk and milk products, I hope that the information it contains will be useful to those dealing with other products, since the principles of processing are in general the same. The book is based on more than 30 years' involvement with research into UHT processing and aseptic filling. During this time I have been fortunate to work with and to talk to many people from whom I have learned a great deal. I benefited from conta.cts with Dr T. R. Ashton (England) and Professor H. Hostettler. (Switzerland), who were pioneers in the commercial development of UHT milk. More recently I have been privileged to know and work with research workers in many countries having a common interest in UHT processing. Of these, I should mention particularly Professors E. L. Thomas, V. A.

Abstract: Climate, climate change, climate fluctuations and climatic trends are only a few of the terms used today, in not only conferences, scientific symposia and workshops, but also parliaments and in discussions throughout society. To climatologists these terms may be well known; to the vast majority of people, however, they are new, and they require definition and explanation. The World Meteorological Organization (WMO) inherited an interest and involvement in the studies of climate and climate change from its predecessor, the International Meteorological Organization (IMo), which was established in 1873. By 1929 the IMO had set up a Commission for Climatology to deal with matters related to climate studies. When, in 1950, the World Meteorological Organization assumed the mantle of the IMO, it retained the commission which, among other responsibilities, had already recognized the need for the definition and explana­ tion of terms used in climatology. It must also be said that much of what we now know about climate derives from the scientific and technical programmes co­ ordinated by IMO and now, to a much greater extent, by WMO. In 1979, the First World Climate Conference made an assessment of the status of knowledge of climate and climate variability, and recommended the establishment of a World Climate Programme. This recommendation was fully endorsed by the Eighth World Meteorological Congress, and the World Climate Programme was subse­ quently established by WMO in co-operation with the International Council of Scientific Unions (ICSU) and the United Nations Environment Programme (UNEP)

Abstract: We live in the silicon age, and the quintessential item that defines our world is the computer. Silicon chips power the computer as well as many other products for work and leisure, such as calculators, radios, and televisions. In the forty years since the transistor was invented, the solid state revolution has affected the lives of almost everyone in the world. Based on silicon, solid state devices and integrated circuits have revolutionized electronics, data processing, communica­ tions, and the like. The computer, especially the personal computer, would be impossible without silicon devices. Only one computer was ever built using vacuum tubes, and the tubes had to be constantly replaced because they generated too much heat and burned out. Silicon devices allowed for reliable switching operations in arrays of hundreds and thousands of discrete devices. As a result, the very substantial industrial base that existed for producing vacuum tubes disappeared -with one exception. That exception is, of course, the CRT, which is evident in televisions, computer displays, and a host of other information display terminals. Until recently, there was nothing that could take its place, and it seemed that the CRT would remain as the electronic medium for all except the simplest displays. The CRT is about to go the way of the other vacuum tubes. It's dead, but doesn't know it yet.

Abstract: This book gives x86 assembly language programmers a view about how to use the resources and features provided by the i386/i486 processor, the newest and most advanced microprocessor from the Intel x86 family. Because the i386/i486 processor is entirely compatible with its predecessor, the 8086/88 processor, this book concentrates on the enhanced features compared to its predecessor. We assume the reader is already familiar with the concepts of 8086/88 assembly language programming. Our goal is to show you the programming methods that apply to powerful features of the i386/i486. The i387 math coprocessor is not discussed in this book. A detailed explanation about how to use each i386/i486 instruction is not covered in this book. However, we list the complete i386/i486 instruction set in Appendix B. Organization of the Book This book is divided into sections to help readers start learning from the concepts that are similar to the 8086/8088 processor. Then, the discussion shifts to the resources and environment of the i386/i486 processor. Throughout the book, real-life program examples are used to illustrate in detail how you can use the enhanced features or functions of the processor. Chapter 1 introduces the i386/i486 architecture and its enhanced features. The discussion includes the operation mode, general registers, segment registers, system registers, and system data structures. Chapter 2 discusses the method that the i386/i486 processor uses to make itself fully compatible with the 8086/88 processor and to define the interrupt vector table address, which is different from the 8086/88 processor.

Abstract: Microelectronics packaging and interconnection have experienced exciting growth stimulated by the recognition that systems, not just silicon, provide the solution to evolving applications. In order to have a high density/ performance/yield/quality/reliability, low cost, and light weight system, a more precise understanding of the system behavior is required. Mechanical and thermal phenomena are among the least understood and most complex of the many phenomena encountered in microelectronics packaging systems and are found on the critical path of neatly every design and process in the electronics industry. The last decade has witnessed an explosive growth in the research and development efforts devoted to determining the mechanical and thermal behaviors of microelectronics packaging. With the advance of very large scale integration technologies, thousands to tens of thousands of devices can be fabricated on a silicon chip. At the same time, demands to further reduce packaging signal delay and increase packaging density between communicat­ ing circuits have led to the use of very high power dissipation single-chip modules and multi-chip modules. The result of these developments has been a rapid growth in module level heat flux within the personal, workstation, midrange, mainframe, and super computers. Thus, thermal (temperature, stress, and strain) management is vital for microelectronics packaging designs and analyses. How to determine the temperature distribution in the elec­ tronics components and systems is outside the scope of this book, which focuses on the determination of stress and strain distributions in the electronics packaging.

Abstract: As the aquaculture industry has expanded throughout the world, it has embraced the experiences of many fields of study to meet increasing technological challenges. The complexities of modern hatchery methodology, more intensive growout systems, and the application of diverse biological and physical sciences to aquatic animal husbandry have reached beyona the ability of most aquaculturists to enjoy an in-depth knowledge of all phases of the aquaculture process. More importantly, in order for tne culturist to have at hand the information necessary to make basic decisions, it requires an extensive library of textbooks and scientific literature. The Aquaculture Desk Reference serves as a concise compila­ tion of tables, graphs, conversions, formulas and design specifica­ tions useful to the aquaculture industry. It also provides examples, in a straightforward manner, of how information in tabulature can be used to derive values for specific system design and process strategies. Tables and graphs in this volume also provide back­ ground documentation and authority for further reference. The Aquaculture Desk Reference is a convenient source book that will alleviate the need for an extensive personal library to access basic information useful for practicing aquaculturists. Many thanks to Mrs. Ruth Aldrich for her assistance in the preparation of this book. My family, friends and associates also deserve my special appreciation for their encouragement and sup­ port.

Abstract: In the past decade, the field of trenchless technology has expanded rapidly in products, equipment, and utilization. This expansion would not have occurred without a strong increase in economic incentives to the user. Because the operating environment has changed, trenchless technology is often the preferred alternative to traditional methods of digging holes and installing conduits. The infrastructure in which we live has become more congested and has to be shared by several users. In addition, the cost of restoring a road or landscaped area after construction may be higher than the cost of installing the conduit. These factors add to the need for trenchless technology-the ability to dig holes without disturbing the surface. In some ways, trenchless technology is a futuristic concept. Ruth Krauss in a children's book of definitions wrote, "A Hole .. .Is to Dig." But this statement is not necessarily true. Today, a hole could be to bore.

Abstract: The fourth annual International Industrial Symposium on the Super Collider, rrssc held March 4-6, 1992, in New Orleans was a great success. Present at this year's conference were 839 attendees representing 24 universities and colleges, 34 states, 13 countries, 17 national laboratories, 11 research centers, many government entities at the local, state and federal levels, and 235 businesses and companies. This year's symposium also included 101 exhibits by 78 organizations. In all categories, this year's participation exceeded the totals of previous years and is an example of the growing support for the Superconducting Super Collider Program. This year's program had many highlights. One of the best was a message from President George Bush, read by Linda Stuntz, Acting Deputy Secretary, Department of Energy. President Bush said that each of us "can be proud of the role that you are playing in building the Collider and in setting the stage for a new era of research and discovery in high energy physics. " The 1992 IISSC's theme was "SSC-Discovering the Future. " This theme was chosen in commemoration of the SOOth anniversary of Columbus's voyage of discovery and the relationship of the SSC with discovery. This theme was articulated by all the speakers in the opening plenary session. Progress on the program was also very evident at this year's symposium. In the pictorial session, 66 photographs from all over the world were displayed to highlight progress in making the SSC a reality.

Abstract: This present text has emerged from the lecture notes for a one semester, first year, graduate level course which has been offered yearly since fall 1985 here in the Electrical and Computer Engineering Department at the University of Colorado at Boulder. Enrollment in the course, however, has not been limited to first year graduate electrical engineering students, but has included seniors, as well as more advanced students, from a variety of disciplines including other areas of engineering and physics. Although other Physical Optics texts exist, the most up-to-date ones are written primarily for undergraduate courses. As is discussed in slightly more depth in the introduction in the beginning of Chap­ ter 1, up-to-dateness is important in a Physical Optics text, as even classical optics has been greatly rejuvenated by the events of the last 30 years, since the demonstration of the laser. The perception of this author is that the needs of a graduate level text are quite different from that of an undergraduate text. At the undergraduate level, one is generally pleased if the student can qualitatively grasp a portion of the concepts presented and have some recollection of where to look them up if need be later in his/her career. A deeper insight is necessary at the graduate level and is generally developed through qualitative analysis of the problems within the subject area.

Abstract: As device dimensions decrease, hot-carrier effects, which are due mainly to the presence of a high electric field inside the device, are becoming a major design concern. On the one hand, the detrimental effects-such as transconductance degradation and threshold shift-need to be minimized or, if possible, avoided altogether. On the other hand, performance­ such as the programming efficiency of nonvolatile memories or the carrier velocity inside the devices-need to be maintained or improved through the use of submicron technologies, even in the presence of a reduced power supply. As a result, one of the major challenges facing MOS design engineers today is to harness the hot-carrier effects so that, without sacrificing product performance, degradation can be kept to a minimum and a reli­ able design obtained. To accomplish this, the physical mechanisms re­ sponsible for the degradations should first be experimentally identified and characterized. With adequate models thus obtained, steps can be taken to optimize the design, so that an adequate level of quality assur­ ance in device or circuit performance can be achieved. This book ad­ dresses these hot-carrier design issues for MOS devices and circuits, and is used primarily as a professional guide for process development engi­ neers, device engineers, and circuit designers who are interested in the latest developments in hot-carrier degradation modeling and hot-carrier reliability design techniques. It may also be considered as a reference book for graduate students who have some research interests in this excit­ ing, yet sometime controversial, field.

Abstract: The use oflubricants began in ancient times and has developed into a major international business through the need to lubricate machines of increasing complexity. The impetus for lubricant development has arisen from need, so lubricatingpractice has preceded an understanding ofthe scientific principles. This is not surprising as the scientific basis of the technology is, by nature, highly complex and interdisciplinary. However, we believe that the under­ standing of lubricant phenomena will continue to be developed at a mol­ ecular level to meet future challenges. These challenges will include the control of emissions from internal combustion engines, the reduction of friction and wear in machinery, and continuing improvements to lubricant performanceand life-time. More recently, there has been an increased understanding of the chemical aspects of lubrication, which has complemented the knowledge and under­ standing gained through studies dealing with physics and engineering. This book aims to bring together this chemical information and present it in a practical way. It is written by chemists who are authorities in the various specialisations within the lubricating industry, and is intended to be of interest to chemists who may already be working in the lubricating industry or in academia, and who are seeking a chemist's view of lubrication. It will also be of benefit to engineers and technologists familiar with the industry who require a more fundamental understanding oflubricants.

Abstract: TOTAL QUALITY MANAGEMENT (TQM) - A COMPETITIVE EDGE In the context of the European and Western manufacturing challenge being set by the 'Far Eastern Machine', it is of critical importance that manufacturing competitiveness is improved in Western companies. The ability to export successfully is becoming even more critical to the economic well-being of developed countries worldwide. The Japanese domination of the motor cycle and domestic consumer markets has had a significant impact on the balance of payments in Western Europe and the USA. All the signs are that Japanese companies are ready and able to enter other markets aggressively, through takeovers, acquisitions and off-shore manufacturing facilities. In Western Europe, the creation of the 'Single Market' in 1992 has provided major opportunities for companies to increase their market share. Unfortunately, many companies in the West have shown an inability to succeed even in their market when faced with tough, well-organized opposition, such as that from the Far East. There is very little time left for Western companies to catch up - the challenge is becoming more fiercely competitive daily. The time to improve competitive edge may be too late for many companies, as the European frontiers are dismantled and the Japanese companies continue to build off-shore plants in Europe. For example, it is a fact that companies are increasingly x PREFACE being forced to achieve world class manufacturing capability in order to compete and, in many cases, survive.

Abstract: This book is written as a result of a personal conviction of the value of incorporating historical material into the teaching of chemistry, both at school and undergraduate level. Indeed, it is highly desirable that an undergraduate course in chemistry incorporates a separate module on the history of chemistry. This book is therefore aimed at teachers and students of chemistry, and it will also appeal to practising chemists. While the last 25 years has seen the appearance of a large number of specialist scholarly publications on the history of chemistry, there has been little written in the way of an introductory overview of the subject. This book fills that gap. It incorporates some of the results of recent research, and the text is illustrated throughout. Clearly, a book of this length has to be highly selective in its coverage, but it describes the themes and personalities which in the author's opinion have been of greatest importance in the development of the subject. The famous American historian of science, Henry Guerlac, wrote: 'It is the central business of the historian of science to reconstruct the story of the acquisition of this knowledge and the refinement of its method or methods, and-perhaps above all-to study science as a human activity and learn how it arose, how it developed and expanded, and how it has influenced or been influenced by man's material, intellectual, and even spiritual aspirations' (Guerlac, 1977). This book attempts to describe the development of chemistry in these terms.

Abstract: TriComm '92 was the fifth in the series of Research Triangle conferences on Computer Communications. This series emerged from a need to provide a forum for the people who are actively involved in Research and Development in the Research Triangle area in which they could present and discuss new ideas in Computer Communications. TriComm '92 was dedicated to High Speed networks. In particular, the program was developed around the following themes: local ATM, preventive and reactive congestion control. routing. transport protocols. traffic measurements, software engineering for telecommunication systems. and standards. I would like to thank all the speakers who agreed to present a paper. and the members of the program committee who patiently refereed the papers despite their busy schedules. I would also like to thank Mr. Ed Bowen, IBM, Research Triangle Park, for covering the expenses for the preparation of the pre-conference proceedings. and Dr. Raif Onvural. IBM, Research Triangle Park, for overseeing the photocopying of the proceedings. I would also like to thank my "Guardian Angel" Ms. Margaret Hudacko. Center for Communications and Signal Processing. State University, who made all the local arrangements. North Carolina Without her help, this conference would have been a complete disaster. Many thanks also go to Norene Miller. Center for Communications and Signal Processing. North Carolina State University. Finally. I would like to thank Mr. Charles Lord, Eastern NC Chapter of the IEEE Communications SOCiety. for providing us with mailing lists.

Abstract: This book addresses an important, but so far neglected, topic: the application of sensory evaluation to quality control. Although several articles have been pub­ lished that have discussed concepts of quality control/sensory evaluation (QC/sen­ sory) programs, Sensory Evaluation in Quality Control is the first publication that addresses this topic in a comprehensive and practical way. This book is com­ prehensive, in that it presents the sensory and statistical information that is needed to design and implement several types of QCfsensory programs at the plant level. The book is practical, in that it provides a step-by-step description of the complete process to implement such programs, and it illustrates this process through real examples encountered by various consumer products companies (e. g. , foods, personal care products, paper products). With this practical information, sensory and quality professionals can design and implement sound QC/sensory programs at the plant level. This book was developed to provide the sensory and quality professional with an overview and guide to apply, in a production facility, the unique techniques that are used to measure sensory responses. Therefore, the book is intended for QC and/or R&D personnel (e. g. , sensory managers and analysts, and quality profes­ sionals) in charge of implementing an in-plant program, as well as for the plant management and plant technical personnel (sensory coordinator and quality pro­ fessionals) who are ultimately responsible for the routine operation of the estab­ lished program.

Abstract: Historical Background lowe my interest in the lactic acid bacteria (LAB) to the late Dr Cyril Rainbow, who introduced me to their fascinating world when he offered me a place with him to work for a PhD on the carbohydrate meta­ bolism of some lactic rods isolated from English beer breweries by himself and others, notably Dr Dora Kulka. He was particularly interested in their preference for maltose over glucose as a source of carbohydrate for growth, expressed in most cases as a more rapid growth on the disaccharide, but one isolate would grow only on maltose. Eventually, we showed that maltose was being utilised by 'direct fermen­ tation' as the older texts called it, specifically by the phosphorolysis which had first been demonstrated for maltose by Doudoroff and his associates in their work on maltose metabolism by a strain of Neisseria meningitidis. I began work on food fermentations when I came to Strathclyde University, and I soon found myself involved again with the bacteria which I had not touched since completing my doctoral thesis. In 1973 lG. Carr, C. V. Cutting and G. c. Whiting organised the 4th Long Ashton Symposium Lactic Acid Bacteria in Beverages and Food and from my participation in that excellent conference arose a friendship with Geoff Carr. The growing importance of these bacteria was subsequently confirmed by the holding, a decade later, of the first of the Wageningen Conferences on the LAB.

Abstract: With a jolt you pull your car to the side of the road, and read the job sign that can't be over one day old: New Home of ABC Inc.; General Contractor, XYZ Construction Co. You think out loud, "I knew the property had been sold," and your eyes roam over the real estate sign with the angled "sold" sticker pro­ claiming to all that the agent has been successful. "Thought the job would have come out on the bid list by now," you mutter as you move back onto the road and head for your office. Later in the day you get the agent on the phone: "Jim, how did XYZ get the ABC job? I saw nothing on the builders' exchange about it." "John, XYZ has been negotiating with ABC for the past six weeks. They did one fine job of selling on old McDuff. Understand they just called on him out of the blue asking for a chance. They put the whole package together, plans and all." "Didn't that tightwad McDuff get another price, Jim?" "Sure did; two, as a matter of fact. He asked me to get two other contractors capable of doing design-build projects. He liked XYZ better. I don't know the prices, but I really feel those boys impressed McDuff by going to him. Were you planning to bid the job?" "Thinking about it," you answer, trying to sound very casual.

Abstract: Within the past decade there has been a veritable explosion of interest in the relationship between food and human behavior. It seems that there is an insatiable desire to find connections between what we eat and what we do. A clear example of this is the proliferation of books, magazine and newspaper articles, and television and radio programs devoted to the topic. More important, however, is the increased attention the scientific community is giving to the study of nutrition and behavior as evidenced by the growth of research, the development of undergraduate and graduate programs, and the number of scientific conferences addressing the prob­ lems in this area. The burgeoning scientific interest in this field makes it a very appropriate time for this book. The principal goal of Nutrition and Behavior: New Perspectives is to provide a comprehensive examination of the scientific evidence dealing with relationships between nutritional variables and behavior. Although findings in research using experimental animals will be introduced, the primary emphasis will be on investigating the nutrition-behavior relation­ ship in our own species. The first chapter provides a historical introduction to the area and examines the techniques used in the scientific assessment of nutrition and behavior. This material gives the reader the necessary background to place recent research on nutrition and behavior within a wider perspective and to evaluate its reliability and validity

Abstract: We have designed and written this book. not as a text nor for the professional mathematician. but for the general reader who is naturally attracted to mathematics as a great intellec­ tual challenge. and for the special reader whose work requires him to have a deeper understanding of mathematics than he acquired in school. Readers in the first group are drawn to mental recreational activities such as chess. bridge. and various types of puzzles. but they generally do not respond enthusiastically to mathematics because of their unhappy learning experiences with it during their school days. The readers in the secondgrouptum to mathematics as a necessity. but with painful resignation and considerable apprehension regarding their abilities to master the branch ofmathematics they need in their work. In either case. the fear of and revulsion to mathematics felt by these readers usually stem from their earlier frustrating encounters with it. vii viii PREFACE This book will show these readers that these fears, frustrations, and general antipathy are unwarranted, for, as stated, it is not a textbook full of long, boring proofs and hundreds of problems, rather it is an intellectual adventure, to be read with pleasure. It was written to be easily accessible and with concern for the mental tranquilityofthe reader who willexperience considerable fulfillment when he/she sees the simplicity of basic mathematics. The emphasis throughout this book is on the clear explanation of mathematical con­ cepts.

Abstract: This edition of well over 50,000 entries not only updates its predecessor but considerably increases the coverage of Latin America and Eastern Europe. I have been aided in this work by two colleagues at Glasgow University Library, Dr Lloyd Davies and Barbara MacMillan, and in general revision by Kate Richard. Close on 20% of the text has been altered. The equivalences, introduced into the last edition, linking acronyms in different languages for the same organization, have been extended. New to this edition is the cross-referencing between a defunct organization and its successor. Otherwise the policies adopted in previous editions have been retained: strictly local organizations are omitted, but the subject scope includes activities of all kinds; the country of origin of a national organization is given in brackets, unless it is the home country of the title language or can be readily deduced from the title itself. Acronyms of parent bodies of subsidiary organizations are also added in brackets. A select bibliography guides the reader to specialist works providing more detailed information. Particularly at a time of such widespread political change affecting organizational structures in so many countries, it is impossible to ensure complete up-to-date accuracy in a work of this kind. Readers are earnestly invited to inform me of any errors and omissions for attention in a later edition of this work. H. H. Bibliography Acronyms, Initialisms and Abbreviations Dictionary. 13th edn.

Abstract: The study of insects at low temperature is a comparatively new field. Only recently has insect cryobiology begun to mature, as research moves from a descriptive approach to a search for underlying mechanisms at diverse levels of organization ranging from the gene and cell to ecological and evolutionary relationships. Knowledge of insect responses to low temperature is crucial for understanding the biology of insects living in seasonally varying habitats as well as in polar regions. It is not possible to precisely define low temperature. In the tropics exposure to 10-15°C may induce chill coma or death, whereas some insects in temperate and polar regions remain active and indeed even able to fly at O°C or below. In contrast, for persons interested in cryopreservation, low temperature may mean storage in liquid nitrogen at - 196°C. In the last decade, interest in adaptations of invertebrates to low temperature has risen steadily. In part, this book had its origins in a symposium on this subject that was held at the annual meeting of the Entomological Society of America in Louisville, Kentucky, USA in December, 1988. However, the emergence and growth of this area has also been strongly influenced by an informal group of investigators who met in a series of symposia held in Oslo, Norway in 1982, in Victoria, British Columbia, Canada in 1985 and in Cambridge, England in 1988. Another is scheduled for Binghamton, New York, USA (1990).

Abstract: The procedures in this manual distill six years of learning about the most efficient acquisition and construction methods in this country for high volume production of housing affordable to low-income people. The people in the Rehab Work Group at The Enterprise Foundation have gathered this information first-hand and conveyed it in training workshops on production management throughout the country. Over 2000 participants in the workshops have included rehab specialists from city housing departments, con­ struction managers of single and multifamily rehab projects, program managers from both nonprofit housing development organizations and city rehab depart­ ments, as well as students in colleges and universities. They are becoming the backbone of a new cadre of effective producers of affordable housing. In the 30 cities and several rural areas where we have both learned and applied these production management techniques, they have resulted in savings of 5, 10, even 25 percent of the cost of housing development. The Enterprise Foundation is a national, nonprofit organization that my wife Patty and I launched in 1982. The Foundation's mission is to see that all very low-income Americans have the opportunity for fit and affordable housing within a generation, and work their way up and out of poverty into the main­ stream of American life.

Abstract: The primary purpose of the first edition of this book was to provide inventors and those who manage technology with sufficient understanding of the patent system to permit them to make use of it with the greatest possible degree of comfort. From the comments that I have received from readers of the first edition, it seems that this purpose was achieved to an appreciable extent. In fact, the audience for the book went beyond this and has been of use to those entering the patent profession and general attorneys who have technology-based clientele. This second edition discusses important changes in the law since the first, including the enactment of new laws as well as new insights into or inter­ pretations of already existing statutes. Along with updating material, I have expanded certain discussions including more examples to illustrate some of the more complex issues covered. In writing this book, I have tried not to lose sight of the underlying philosophy of the patent laws as expressed in ARTICLE 1, SECTION 8 of the United States Constitution: The Congress shall have the power to promote the sciences and useful arts, by securing for limited time to authors and inventors the exclusive right to their respective writings and discoveries. Encouragement of communication between an inventor and the general public is, therefore, the primary purpose and objective of the patent laws.

Abstract: This book is one of the few English language texts devoted to the subject of quality costing. The material is based on research work carried out by the authors at the Manchester School of Managememt, UMIST, over the last nine years or so. The research has been mainly in manufac­ turing organizations but work has also been conducted in non-manufac­ turing concerns (e. g. marketing and service operations, and commerce). The book will provide managers with sound practical advice on how to define, collect, analyse, report and use quality costs. The text covers all the main aspects of quality costing and an attempt has been made to structure the book in the sequence by which organizations should set about a quality costing exercise. The book opens by examining the background of quality costing. This is followed by chapters on definitions of quality costs, collection of quality costs, analysis and reporting of quality costs, and the uses of quality costs. Examples from manufacturing organizations and non­ manufacturing situations are used throughout the first five chapters to illustrate the key points discussed in the text.

Abstract: Within the last decade, the high and continuing demand for gold has prompted a global gold rush on a scale never before seen, not even in the heady days of Ballarat, California and the Yukon. Gold is being sought on every continent and, with very few exceptions, in every country around the world. Such interest and fierce competition has demanded considerable innovation and improvement in exploration techniques paralleled by a rapid expansion of the geological database and consequent genetic modelling for the many different types of gold deposits now recognized. This proliferation of data has swamped the literature and left explorationist and academic alike unable to sift more than a small proportion of the accumulating information. This new book represents an attempt to address this major problem by providing succinct syntheses ofall major aspects ofgold metallogeny and exploration, ranging from the chemical distribution of gold in the Earth's crust, and the hydrothermal chemistry of gold, to Archaean and Phanerozoic lode deposits, epithermal environments, chemical sediments, and placer deposits, and culminates in chapters devoted to geochemical and geophysical exploration, and the economics of gold deposits. Each chapter is written by geoscientists who are acknowledged internationally in their respective fields, thus guaranteeing a broad yet up-to-date coverage. In addition, each chapter is accompanied by reference lists which provide readers with access to the most pertinent and useful publications.

Abstract: I am pleased to present the Fifth Edition of the Plastics Engineering Handbook. Last published in 1976, this version of the standard industry reference on plastics processing incorporates the numerous revisions and additions necessitated by 14 years of activity in a dynamic industry. At that last printing, then-SPI President Ralph L. Harding, Jr. anticipated that plastics pro­ duction would top 26 billion pounds in 1976 (up from 1.25 billion in 1947, when the First Edition of this book was issued). As I write, plastics production in the United States had reached almost 60 billion pounds annually. Indeed, the story of the U.S. plastics industry always has been one of phenomenal growth and unparalleled innovation. While these factors make compilation of a book such as this difficult, they also make it necessary. Thus I acknowledge all those who worked to gather and relate the information included in this 1991 edition and thank them for the effort it took to make the Plastics Engineering Handbook a definitive source and invaluable tool for our industry.

Abstract: 1 Sweetness and food selection -- 2 The carbohydrate—sucrose -- 3 Non-sucrose carbohydrates -- 4 Sugar alcohols -- 5 Intense sweeteners -- 6 Natural high potency sweeteners -- 7 Sweetener markets, marketing and product development -- 8 Sweeteners and dental health -- 9 Sweeteners and metabolic disorders -- 10 Sweeteners and body weight -- 11 Sweeteners: statutory aspects.

Abstract: The study of sweetness and sweeteners has recently been an area well­ served by books at all levels, but this volume was planned to fill what we perceived as a gap in the coverage. There appeared to be no book which attempted to combine a study of sweetness with a thorough but concise coverage of all aspects of sweeteners. We set out to include all the important classes of sweeteners, including materials which do not yet have regulatory approval, so that clear comparisons could be made between them and their technological advantages and disadvantages. To achieve our first aim, of sufficient depth of coverage, the accounts within this volume are comprehensive enough to satisfy the requirements of a demanding readership, but cannot be exhaustive in a single volume of moderate proportions. The second aim, of breadth and conciseness, is satisfied by careful selection of the most pertinent material. For the purposes of this book, a sweetener is assumed to be any substance whose primary effect is to sweeten a food or beverage to be consumed, thus including both the nutritive and non-nutritive varieties, from the ubiquitous sucrose to the lesser known, newer developments in alternative sweeteners. The volume has its contents structured in a logical manner to enable it to be used in an ordered study of the complete subject area or as a convenient reference source.

Abstract: We are witnessing an increased awareness of the earth's environment. Examples are easily seen in the rise of 'Green Parties' across Europe, North America, Australasia, and lately Eastern Europe. The public outcry following industrial mishaps in Alaska, Chernobyl, Basel, and Bhopal, as well as the renewed legislative activity, such as the Clean Air Act in the USA and the European Community directive to member nation concerning the control of release of genetically engineered organisms are further examples of the general interest in the biosphere. The 'Ozone hole', 'Greenhouse gases', and 'Genetically engineered Microorganisms' have gained public profiles, and are discussed widely in newspapers, magazines and the electronic media. A recent educational survey of nations, belonging to the Organisation for Economic Co-operation and Development (OECD) showed that school children are more literate with ecological terms (as listed above) than with 'pure' scientific terms, like 'phloem', 'mitosis', 'proton', or 'Jurasic period'. Perhaps the increase in awareness is cyclical, being fed by non-scientific, sociological and economic advances. The late 1960s/early 1970s saw a major increase in environmental consciousness. Anti-pollution groups were founded, healthfood shops and naturopathy became acceptable as did recycling, the use of lead-free gasoline, and the reduced usage of environmental toxins, like DDT and PCB. For example, Monsanto Chemical Company instigated a self-imposed halt to the manufacture of PCB in the mid-seventies. Chemical companies started to look at biodegradable herbicides, slow release fertilizers, and specifically targeted pesticides.

Abstract: We live in a changing world; one in which there is much concern and discussion about the topics of global change, loss of biodiversity, and increasing threats to the sustainability of ecosystems. The effects these changes may have on the environment have lead governments and sCientists to make predictions as to how soon changes might occur, where, and with what impact for large and small regions of the Earth. Along with this concern for change in various regions has come the need to understand the role of boundaries between these regions and between landscape elements. Much previous ecological research has dealt with processes within relatively homogeneous landscape units or even the collective characteristics of a composite landscape. Now, however, there is an appreciation that abiotic and biotic components move across heterogeneous landscapes and that the boundaries between these units take on important control functions in this dynamic spatial system. Furthermore, landscape boundaries (or ecotones) are important not only in satisfying life-cycle needs of many organisms, but generally are characterized by high biological diversity.

Abstract: Most practitioners and students of polymer chemistry are familiar, in general terms at least, with the established methods of polymer synthesis - radical, anionic, cationic and coordination addition polymerization, and stepwise con­ densation and rearrangement polymerization. These methods are used to synthesize the majority of polymers used in the manufacture of commercially important plastics, fibres, resins and rubbers, and are covered in most introduc­ tory polymer chemistry textbooks and in most undergraduate and graduate courses on polymer science. Fewer polymer chemists, however, have much familiarity with more recent developments in methods of polymer synthesis, unless they have been specifically involved for some time in the synthesis of speciality polymers. These developments include not only refinements to established methods but also new mechanisms of polymerization, such as group transfer and metathesis polymerization and novel non-polymerization routes to speciality polymers involving, for example, the chemical modification of preformed polymers or the linking together of short terminally functionalized blocks.

Abstract: The procedures in this manual distill six years of learning about the most efficient acquisition and construction methods in this country for high volume production of housing affordable to low-income people. The people in the Rehab Work Group at The Enterprise Foundation have gathered this information first-hand and conveyed it in training workshops on produQtion management throughout the country. Over 2000 participants in the workshops have included rehab specialists from city housing departments, con­ struction managers of single and multifamily rehab projects, program managers from both nonprofit housing development organizations and city rehab depart­ ments, as well as students in colleges and universities. They are becoming the backbone of a new cadre of effective producers of affordable housing. In the 30 cities and several rural areas where we have both learned and applied these production management techniques, they have resulted in savings of 5, 10, even 25 percent of the cost of housing development. The Enterprise Foundation is a national, nonprofit organization that my wife Patty and I launched in 1982. The Foundation's mission is to see that all very low-income Americans have the opportunity for fit and affordable housing within a generation, and work their way up and out of poverty into the main­ stream of American life.

Abstract: Following their recognition by GUmbel (1874), lamprophyres were treated for an entire century as little more than obscure curiosities. Although this situation has changed recently, with a flowering of publications and active workers, lamprophyres remain almost the only group of igneous rocks which have not yet received attention in a dedicated monograph. In five exploratory reviews (1977-1987), the writer aimed to set out what was known about these rocks. The lUGS Subcommission on igneous rock systematics had meanwhile presented its nomenclatural framework (Streckeisen 1979). All this has now been overtaken by a recent explosion of interest, epitomized not least by lamprophyres' greater prominence in the 4th International Kimberlite Conference Proceedings. More data have become available since 1985 than over the entire previous century, and it is obviously impossible for such an extraordinary outpouring to be fully reviewed in this first, preliminary book. At the risk of dissatisfying some readers, therefore, this book concentrates on factual matters, and on a broad overview rather than minutiae. Because not even a world map of known lamprophyres was previously available, almost half the book is deliberately taken up by the first global lamprophyre compilation, and its commensurately extensive Bibliography. Such a compendium of largely objective information is believed to be of more immediate interest and lasting value than a premature pottage of petrogenetic polemic. Chapters 1-7 bring previous studies up to date, and concentrate on factual information.

Abstract: In the field of compressed gases and related equipment, there is an expanding core of essential knowledge that people handling and using these materials should be familiar with or should know where to find when necessary. The focus of this book concerns the properties and the accepted means of trans­ portation, storage, and handling of compressed gases. This Handbook is simul­ taneously intended as an overview of the subject and a source of supplementary information. It is also intended to serve as a guide to pertinent federal regulatory requirements and published standards of the Compressed Gas Association and other standards-writing bodies. Readers are advised that the CGA technical pamphlets remain the official state­ ment of policy by the Association on a particular matter. Reference is made throughout this text to the numerous technical pamphlets published by the Com­ pressed Gas Association. Some of these publications have been incorporated by reference into federal, state, provincial, and local regulations. Since these pam­ phlets are reviewed on a periodic basis, wherever the text of this Handbook may be found in conflict with corresponding information in the CGA technical pam­ phlets, the latter shall take precedence.

Abstract: Most of the topics in applied mathematics dealt with in this handbook can be grouped rather loosely under the term analysis. They involve results and techniques which experience has shown to be of utility in a very broad variety of applications. Although care has been taken to collect certain basic results in convenient form, it is not the purpose of this handbook to duplicate the excellent collections of tables and formulas available in the National Bureau of Standards Handbook of Mathematical Functions (AMS Series 55, U.S. Government Printing Office) and in the references given therein. Rather, the emphasis in the present handbook is on technique, and we are indeed fortunate that a number of eminent applied mathe­ maticians have been willing to share with us their interpretations and experiences. To avoid the necessity of frequent and disruptive cross-referencing, it is expected that the reader will make full use of the index. Moreover, each chapter has been made as self-sufficient as is feasible. This procedure has resulted in occasional duplication, but as compensation for this the reader may appreciate the availability of different points of view concerning certain topics of current interest. As editor, I would like to express my appreciation to the contributing authors, to the reviewers, to the editorial staff of the publisher, and to the many secretaries and typists who have worked on the manuscript; without the partnership of all of these people, this handbook would not have been possible.

Abstract: Processing of fine particles has presented numerous challenges to scientists and engineers for many years. Considerable progress has al ready been made in meeting these challenges across various fields of applications around the world. Research on every aspect of fine particle processing has gained momentum in recent years, resulting in the development of new processes, improved products, and better understanding of the science and engineering fundamentals of fine particles. This symposium addressed the recent progress in fine particles processing, particularly in the production of minerals for chemicals, pigments and metal production, ceramic materials, and fossil fuels. This book represents the edited proceedings of the International Symposium on Advances in Fine Particles Processing, where selected peer-reviewed papers describe current practices, review the state of the art and report original fundamental and applied research on fine particle production, sizing, characterization of the interface, fluid flow, and interparticle colloidal interactions, leading to dispersion, flocculation and flotation. Processing of fine particles by multi-chemical, physical and biological phenomena has also been addressed. Accordingly, the book consists of seven parts, with each part addressing a specific topic. Part One deals with production of fine particles by comminu­ tion methods where different milling practices, mathematic modeling and physical­ chemical control methods are reported. Part Two covers particle flow properties in various fluids. Part Three addresses surface and colloidal phenomena in fine particle processing, while Part Four continues this topic but with emphasis on clay minerals.

Abstract: This volume records the papers presented in Warsaw on the meeting of the International Society of Arterial Chemoreception (LS. A. C. ) organized as a Satellite Symposium of the XXXI International Congress of the Union of Physiological Sciences (I. U. P. S. ) in Helsinki in July 1989. It is a 30 years old tradition to hold periodically international meetings on recent developments in chemoreceptor research and to exchange information between those of us interested in chemoreception. The first meeting was organized by B. B. Lloyd in Oxford in 1959. Later on, similar international meetings were held at irregular intervals. In 1966, R. W. Torrance organized the second meeting again in Oxford. In 1973, the third meeting was organized in Bristol (U. K. ) by M. J. Purves. In 1974, a fourth meeting combined with the XXVI I. U. P. S. Congress in Delhi was organized by A. S. Paintal in Srinagar (Kashmir, India). In 1976, H. Acker organized the fifth meeting in Dortmund (F. R. G. ), and in 1979, C. Belmonte in Valla­ dolid (Spain) organized the sixth international meeting commemorating the 50th anniversary of Fernando de Castro publishing his classical work on the structure and possible function of the carotid body. In 1982, the seventh meeting was due to D. J. Pallot in Leicester (U. K. ), in 1985 - the eighth one due to A. J.

Abstract: This book is designed to fulfill a dual role. On the one hand it provides a description of the rheological behavior of molten poly­ mers. On the other, it presents the role of rheology in melt processing operations. The account of rheology emphasises the underlying principles and presents results, but not detailed deriva­ tions of equations. The processing operations are described qualita­ tively, and wherever possible the role of rheology is discussed quantitatively. Little emphasis is given to non-rheological aspects of processes, for example, the design of machinery. The audience for which the book is intended is also dual in It includes scientists and engineers whose work in the nature. plastics industry requires some knowledge of aspects of rheology. Examples are the polymer synthetic chemist who is concerned with how a change in molecular weight will affect the melt viscosity and the extrusion engineer who needs to know the effects of a change in molecular weight distribution that might result from thermal degra­ dation. The audience also includes post-graduate students in polymer science and engineering who wish to acquire a more extensive background in rheology and perhaps become specialists in this area. Especially for the latter audience, references are given to more detailed accounts of specialized topics, such as constitutive relations and process simulations. Thus, the book could serve as a textbook for a graduate level course in polymer rheology, and it has been used for this purpose.

Abstract: Although catfish have been farmed for about 30 years and catfish farm­ ing is the most successful aquacultural enterprise in the United States, there are those who contend that catfish farming is still as much of an "art" as it is a science. This position is difficult to refute completely, particularly considering that some practices used in catfish farming ap­ pear to have little scientific basis. Skill coupled with a small dose of mysticism certainly playa role in the culture of catfish, and the catfish producer is faced with the unenviable task of rearing an animal in an environment that requires considerable management. Certain aspects may still be an "art" because research and technical information needed to support the industry have lagged behind industry growth; however, the basic principles underlying catfish farming are based on sound scientific evidence whose foundation was laid in the 1950s by work conducted at state and federal fish hatcheries in the southeastern and midwestern United States. Since that time, several university and government laboratories have expanded the scientific base for catfish farming. As a result, considerable information is available, but it is gen­ erally fragmented and exists in a multitude of diverse scientific and trade journals. The material is often too technical or abstract to be com­ prehensible to fish culturists and personnel in allied industries. This book fits the definition of the term handbook in the sense that it is intended as a book of instruction or guidance as well as a reference.

Abstract: A recent national survey of geology students indicated that, In a subject so fundamental and yet so varied, every although they saw the need for a basic training in map­ geologist will have his own views on geological maps - the work, the three-dimensional aspects involved formed the matters needing emphasis, the best methods of interpreta­ single most difficult part of an introductory geology tion, good examples of maps, and so on. Instructors may course, and that it was generally taught in a way both ab­ therefore urge in their taught courses different priorities stract and dull. At the same time, there was no book which from those given here, and, although a wide range of maps puzzled students could turn to for explanations; no book and map exercises is included, will prefer to continue to which told them more about real geological maps. This use their own 'pet' examples. But this is meant primarily to book is an attempt to fill that need. It is based on the view be a book for the student - to turn to for clarification, for that in these days of increasing specialisation the geological further information, and simply to learn a little more about map remains the vital coordinating document, and that the geological maps.

Abstract: It was a compliment to me to be asked to prepare the fourth edition of Westcott's Plant Disease Handbook, and the decision to accept the responsi­ bility for the fourth edition and now the fifth edition was not taken lightly. The task has been a formidable one. I have always had a great respect professionally for Dr. Cynthia Westcott. That respect has grown considerably with the completion of the two editions. I now fully realize the tremendous amount of effort expended by Dr. Westcott in developing the Handbook. A book such as this is never finished, since one is never sure that everything has been included that should be. I would quote and endorse the words of Dr. Westcott in her preface to the first edition: "It is easy enough to start a book on plant disease. It is impossible to finish it. " This revision of the Handbook retains the same general format contained in the previous editions. The chemicals and pesticides regulations have been updated; a few taxonomic changes have been made in the bacteria, fungi, and mistletoes; the changing picture in diseases caused by viruses and/or viruslike agents has been described. A few new host plants have been added, and many recently reported diseases as well as previously known diseases listed now on new hosts have been included. In addition, photographs have been replaced where possible, and the color photograph section has been retained.

Abstract: Matrix analysis of structures is a vital subject to every structural analyst, whether working in aero-astro, civil, or mechanical engineering. It provides a comprehensive approach to the analysis of a wide variety of structural types, and therefore offers a major advantage over traditional metho~ which often differ for each type of structure. The matrix approach also provides an efficient means of describing various steps in the analysis and is easily programmed for digital computers. Use of matrices is natural when performing calculations with a digital computer, because matrices permit large groups of numbers to be manipulated in a simple and effective manner. This book, now in its third edition, was written for both college students and engineers in industry. It serves as a textbook for courses at either the senior or first-year graduate level, and it also provides a permanent reference for practicing engineers. The book explains both the theory and the practical implementation of matrix methods of structural analysis. Emphasis is placed on developing a physical understanding of the theory and the ability to use computer programs for performing structural calculations.

Abstract: The Gramineae, or grass family, is second in size only to the Compositeae, or sunflower family. It is among the most important plant families in the world. The major food crops of the world are found in the grass family. From time immemorial, grasses have provided food and shelter for humanity, domesticated livestock, and wildlife; without grasses, these forms of life might cease to exist. The grass family is large in size, diverse in habit, and ubiquitous in distribution. Earth would be bleak and bare, indeed, in the absence of this life-sustaining plant family. In addition to its economic and industrial value, the grass family has some ornamental value. It provides us with physical sustenance and gives us much pleasure and satisfaction in its ornamental forms. The purpose of this book is to point out the value and usefulness of grasses as ornamentals and to deline:tte their attributes and uses in the home, in the garden, and in the landscape. Ornamental grasses serve a unique and significant purpose in ornamental horticulture. Horticulturists, other plant scientists, and nursery personnel are more fully aware of the value and usefulness of grasses as ornamentals than is the general public. It is mainly for this reason that this work is directed toward the home gardener and the scientist alike, in the hope of enhancing reader appreciation of the roie grasses play in ornamental horti­ culture.

Abstract: At the time of the writing of the fourth edirion of this textbook, the agricultural economy in the United States and Canada was depressed. The prices paid to farmers for their grain crops were very low, and consequently most farmers in North America could not afford to buy a new tractor when needed; there­ fore, the sales of tractors and other farm machines were much below normal. The farmer who was the victim of the depressed economy was forced to "make do." Instead of purchasing a new tractor when the old one needed to be replaced, the farmer usually purchased a used or second-hand tractor or repaired the old one. In a strict sense, tractors usually do not wear out; instead, they become obsolete. The farmer who owns an obsolete tractor would prefer to replace it with one having more power, more speeds, more conveniences, a better hydraulic system, lower operating cost, or all of the above. But farmers in the United States, Canada, and other industrial nations will continue to want to purchase tractors that have all of the features, in­ cluding microprocessors, found on other vehicles.

Abstract: During the past decade there has been a dramatic change in the nature of mobile communications technology and its impact on the general communic­ ations environment. In the 1970s, mobile radio was a minority activity in communications, based on relatively unsophisticated technology. The 1980s, however, have seen the emergence of analogue cellular systems and the definition of future digital systems, and the predicted demand for these services is such that investigations into the use of higher frequency bands have already begun. It is predicted that, by the late 1990s, the 'personal communications' world will have resulted in the majority of adults in Europe and North America being dependent on radio-connected terminals of various kinds for more than 50% of their total telecommunications needs. The technology which will form the basis of this revolution has now been defined, at least in outline, and the fixed and mobile equipment that will be used in systems of the future will bear little resemblance to that available even ten years ago. It is impossible within the confines of a single, relatively short book to cover all the subject areas needed for a study of this exciting and expanding field of technology. We have, perforce, been selective and have chosen those topics which we believe to be of primary importance at the present time.

Abstract: In the era of Information Technology, the computer is the machine-tool. Designers and planners are information workers and many have turned to CAD technology, hoping to find something that will ensure survival in the increasingly competitive business climate. The new problem relates not to any limitations of systems, but to the lack of knowledge on how to implement, manage and control the CAD technology. This book is aimed at design professionals, planners and managers. Although references and examples relate to building and construction work, most of the principles are unlikely to differ whatever the application. As a result, it should be useful in the fields of mechanical engineering and manufacturing industry too. Chapter 13 deals with applications in construction planning, space planning and facilities management. Emphasis throughout is on people, responsibilities, applications, organisation and procedures. The design process is highly interactive. Manual drawing, or use of a computer drafting system to mimic this, inevitably leads to inconsistencies within in the design information. Computer modelling of projects presents better opportunities and the many techniques range from 2-D modelling to solid modelling. A blend of 2-D and 3-D methods to suit the application is essential today. System planning itself requires a carefully managed feasibility study comprising preliminary and detailed phases. Objectives and requirements of the office must be set down. Then there is something to compare the available systems with. The chosen system must be capable of evolving to meet an ever-changing future.

Abstract: RajB KNRao Conference Director, Birmingham Polytechnic Condition Monitoring and Diagnostic Engineering Management (COMADEM) is a relatively new field that has already made its mark in a wide range of industries. But all the signs are that even more will be required of researchers in the field over the next decade, for COMADEM directly addresses a whole range of issues that are likely to become increasingly important to companies as competitiveness increases along with the uncertainties resulting from rapid technological change. Already for example, businesses are having to scrutinize the economics of plant and machinery in greater detail than ever before; reliability is becoming a crucial factor as the costs of unscheduled breakdowns rise and there is increasing pressure on companies to demonstrate and assure improved health and safety conditions, especially in light of the growing number of catastrophic accidents that have occured throughout the world. Because it offers solutions to these and similar problems, COMADEM is now gaining an international reputation as a problem-solving, user-friendly and financially beneficial multi-discipline with immense potential. Many people at the senior management level are now convinced that COMADEM has much to offer and are wasting no time in reaping maximum benefit from the latest developments. The fact that the first UK informal seminar on COMADEM - COMADEM 88 - proved to be a great success and had a truly international flavour reflected this growing interest in the new field.

Abstract: Ralph A. LewiQand Lanna Cheng In physics, the discovery of new (more properly, hitherto undetected) particles has often resulted from a search: like the discovery of America, their existence had been postulated but their actual existence awaited confirmation. In biology, new discoveries are rarely made in this way. The existence of an alga like Prochloron, as a putative ancestor of chloro­ plasts, had been postulated, but in fact its discovery was a consequence of fortuitous events. Green algal symbionts in didemnid ascidians had been known for decades to a few marine zoologists who had worked in coral reef areas, but nobody had bothered much about them. When we happened to find them, under boulders on a seashore in Baja California, Mexico, where we were taking part in a student expedition, we didn't bother much either at first, though they worried us a little. With our portable microscope we could see no nuclei in the cells, which, according to the dogma accepted at the time, indicated that they were blue-green algae-yet they didn't look blue-green. They were leaf-green, like green algae and higher plants. We made desultory attempts to grow them in culture, in variously enriched seawater media, but failed. (This proved to be a frustrating experience, all too frequently repeated on subsequent expeditions. ) We collected enough for electron microscopy, though, and transmission electron microscopy (TEM) studies indicated that the cells were unequivocally prokaryotic.

Abstract: Communications * Standard Dictionary is a comprehensive compilation of terms and definitions used in communications and related fields. Communications is defined as the branch of science and technology concerned with the process of representing, transferring, and interpreting the meaning as­ signed to data by and among persons, places, or machines. Communication is defined as the transfer of information between a source (trans­ mitter, light source) and a sink (receiver, photodetector) over one or more chan­ nels in accordance with a protocol, and in a manner suitable for interpretation or comprehension by the receiver; or as a method or means of conveying informa­ tion of any kind from one person or place to another. In short, communications is a branch of science and technology, whereas com­ munication pertains to the actual transfer of information. Thus, the word com­ munication should be used as a modifier, as in communication center, communi­ cation deception, and communication line, just as in the field of electronics one speaks of electronic devices and electronic circuits.
