Abstract: The Regulated Chemicals Directory"lM is meant to be a convenient source of information for everyone who needs to keep up-to-date regarding the regulations and recommendations that pertain to chemical substances. The RCD™ is designed to be the first reference book to consult when beginning compliance efforts. Every regulatory or advisory list used in the RCD™ is keyed to its source, to help readers who need more detailed information on regulations, recommendations, or guidelines readily locate source documents. Some organizations now center their compliance efforts on computerized information stored in cross-referenced databases. A unique feature of the RCDTM is the availability of an electronic version suitable for use on IBM-compatible personal computers, download onto mainframes and CD-ROM players. Both the print and electronic versions are updated with the same timeliness. For more information on the electronic versions of the Regulated Chemicals DirectoryTM, contact Chapman & Hall directly (One Penn Plaza, New York, NY 10119, fax-212-564-1505). Many companies working on product development need information on what may be regulated in the future. The RCD™ provides selected information on pending regulations and in-progress testing lists, which can provide a starting place for tracking future regulatory considerations. Information for the RCD™ is continually gathered and updated. Suggestions from readers for information that should be added to the RCD™ or for other ways to improve the book are welcomed by Chapman & Hall. - Patricia L. Dsida, Pres.

Abstract: Flavorwise and texturewise pecans are the "Queen of the Edible Nuts. " This has been verified by salters, bakers, confectioners and ice cream manufacturers in America and western Europe. Hickory nuts and macadamia nuts are close behind, but are available only in limited supply. Pecans are among the nuts highest in oil content. In general, the varieties of nuts with the highest oil content are also rich in flavor and tender in texture. Some varieties of pecans (i. e. , Schley and Curtis) have been shown to contain as much as 76% oil. The oil in pecans is highly unsaturated, which means it is desirable from a nutritional standpoint but that it is also highly susceptible to oxidation which can cause pecans to tum stale and rancid. Pecans used in confections, bakery goods, cereals, or in snacks are more subject to staleness and rancidity than most nuts because these products are often stored at ambient temperatures. For this reason, pecans are considered to be semi-perishable and are not used in some "fine" products due to their limited shelf-life. Research at the Georgia Experiment Station has shown that raw pecans or most pecan products may be held in good condition for more than 20 years if freezing is the mode of preservation. However, development of new products demands that pecans be stored at ambient temperatures for extended intervals. Pecan 'meat' is easily bruised during shelling and handling.

Abstract: This book was inspired by the revolution in geographical information systems during the late 1970s and 1980s which introduced to many the concept of computer-based information systems for spatially referenced data. The map, the aerial photograph and the satellite image were wedded to a database of textual information through the rapidly developing technology of powerful graphics workstations. This brought the skills of the geographer to a wide range of disciplines and specialists. But this book is not about the basic concepts of geographical information systems themselves. It is not about hardware or software per se, nor the integral concepts of geo-referenced data handling built into such systems; these are to be found in a growing number of introductory texts on the subject. Instead the focus of this book is on of geo-information management. the much wider issues While an understanding of the systems, their capabilities and limitations is necessary, of greater importance to the long term application of geographical understanding to problem solving is the wider context of information handling. Spatial data are becoming increasingly important in understanding the issues that confront the world. Chapter 1 is a discussion of the general issues which relate to management and information systems. It concludes with review of spatial decision support systems which are of increasing importance to the GIS community.

Abstract: This edition of over 60 000 entries, including significantly more than 20% new or revised material, not only updates its predecessor but also continues the policy of extending coverage to areas dealt with only sparsely in previous editions. Special attention has been paid to the Far East, Australasia and Latin America in general, and to the People's Republic of China in particular. The cross-referencing between a defunct organization and its successor (indicated by ex and now) introduced into the last edition, has been extended. Otherwise the policies adopted in previous editions have been retained. All kinds of organizations are included - international, national, governmental, individual, large or small - but strictly local organizations have been omitted. The subject scope includes activities of all kinds, in the fields of commerce and industry, education, law, politics, public administration, religion, recreation, medicine, science and technology. 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 deduced readily from the title itself. Acronyms of parent bodies of subsidiary organizations are also added in brackets. Equivalences are used to link acronyms in different languages for the same organization. A select bibliography guides the reader to specialist works providing more detailed information.

Abstract: This book has passed through a number of editions each involving some modifications while retaining the general character of the first. The most substantial changes occurred in the fifth (1983), but that is now out-of-date. Mycology has not been immune from the rapid evolution of biology in the past decade and the preparation was a long way beyond the capacity of the older writer (C.T.I.). So a younger one (H.J.H.) has collaborated with him. Substantial changes have been made throughout, particularly in relation to taxonomy but in general Chapters 1-7 have undergone relatively little revision. However, this is not true of Chapters 8-12 where the influence of the younger author is paramount. The basic idea of the book remains, namely to present fungi as living organisms profoundly affecting the lives of other kinds of living organisms, especially Man. Their study is of the greatest importance and what is more it is great fun. Many of the diagrams have been retained, but some have been redrawn and new ones added. Weare pleased to acknowledge the patience and artistic skills of Mrs Lindsay J. Wilson in producing these. Some coloured plates have also been introduced from photographs taken by H.J .H.

Abstract: A long and varied experience in many areas of electronic circuit design has convinced me that capacitors are the most misunderstood and misused electronic component. This book provides practical guidance in the understanding, construction, use, and application of capacitors. Theory, combined with circuit application advice, will help to under­ stand what goes on in each component and in the final design. All chapters are arranged with the theory of the dielectric type discussed first, followed by circuit application information. With all chapters arranged in the same manner, this will make reading and using this book for reference easier. A practical glossary of terms used in the capacitor industry is included. The first chapter covers basic information that applies to all types of capacitors. Each following chapter addresses a different capacitor dielectric. This book could have been titled: 'Everything You Wanted To Know About Capacitors, But Were Afraid To Ask .. .' ix Preface THE CAPACITOR HANDBOOK Chapter 1 Fundamentals For All Capacitors For all practical purposes, consider only the parallel plate capacitor as illustrated in Fig. 1.1-two conductors or electrodes separated by a dielectric material of uniform thickness.

Abstract: The term 'converting' is in widespread use yet there is no general agreement on its precise definition and scope. The converting industry is notoriously diffuse, encompassing wide web coating operations in paper and plastics packaging, trimming, sheeting and the intricate details of high quality bound book production. A bewildering array of jargon is in use, much of it based on customs and practices passed down for several generations and, increasingly, on new terms originating from the USA or mainland Europe. This book aims to satisfy the wishes of many converters for a standard reference work which can be used for education and as an aid to communication. The dictionary gives definitions of terms which may be encountered in any of the diverse group of technologies that is included under the general heading 'converting' which is defined as 'the process of transforming one or more preformed raw materials, usually in web or sheet form, to a state suitable for end use or further processing'. Thus both calendering and coating are included but only with reference to operations which are carried out separately from the paper machine, otherwise known as 'off-machine processes'. Also in­ cluded are methods of production of cartons, books, finished and coated papers, boards and laminates, and many other items of relevance to the paper and board, film, laminating, packaging and allied industries.

Abstract: Eutrophication is a problem which became widely recognised by the scientific community in the 1940s and 1950s. It raised public concern, resulting in increased research effort and expenditure on management techniques through the 1960s and 1970s, recognised as a distinct problem of water pollution, though linked with the more gross effects of organic pollution. In the 1980s it became less fashionable - replaced in the public's eye and the politician's purse by newer problems such as acid rain. It remains however, one of the biggest and most widespread problems of fresh waters, particularly of lakes and an increasing problem for estuaries and coastal waters. It is one with which almost all water scientists and engineers in urbanised areas of the world have to cope. Technical methods for the reversal of eutrophication, such as nutrient removal, have been developed and applied successfully in some instances. They are not widespread however, and where they are feasible, they are often expensive and may be politically difficult to implement. In the last decade, attention has focussed upon less expensive lake manipula­ tion techniques, such as destratification and biomanipulation, which aim to minimise rather than elimininate the detrimental effects of eutrophication. These are becoming more widely applied. Prediction of the potential problems in lakes and catchments which have not yet suffered the full effects of eutrophication is now accurate enough to be of direct benefit to river basin management.

Abstract: The decision to write a book about the practical aspects of the baculovirus expression system stems from the numerous phone calls for help we have had, and from the many visitors to our labora­ tories requiring assistance to find the elusive polyhedrin-negative virus containing their favourite gene. We have also organized two expression system workshops and from the manuals we wrote for these, it seemed a logical progression to extend them into book form. We appreciate that those who are 'old-hands' at the baculovirus expression system may have differing views on some of our procedures, but the methods in this book are presented in the light of our own experiences in the laboratory and from our practical workshops, and we hope that the book will be especially useful to those new to the system. The first three chapters give the background information to the baculovirus expression system, and includes advice on how to choose the right transfer vector and discusses the various methods that are available to select recombinant viruses. The practical chapters concentrate on those aspects which are novel to the baculovirus system (insect cell culture, virus amplification and titration, etc. ) and, in general, leave the standard molecular biological techniques to the other excellent laboratory manuals that are available. However, for completeness sake and to avoid constant reference to other manuals, we have included brief details of some standard techniques where they are integral to the success of the baculovirus protocols.

Abstract: As I write this short preface, the red orb of Mars is high in the eastern sky, and is brighter than it has been for many years. Last night my telescope again revealed the strange polar hood which is a feature of the planet at this time in its cycle. Because of its current prominence in the night sky, it is a very appropriate time to bring together and reappraise what we know of Mars and look forward to the next wave of planetary exploration. The initial notion of writing a book about Mars is an exciting one; the practicalities involved in working through and completing the project are, however, more than a trifle exacting. The first problem I encountered was the sheer vastness of the library of information about Mars which now exists. The second was the natural extension of the first, that is, how best to analyse it and reach widely acceptable interpretations. I have tried to write the story of Mars in a logical and unbiased way, however, we all have our individual prejudices, and I would be less than truthful if I did not admit to personal bias here and there. With this in mind, I apologise to any authors who may feel either misinterpreted or less than adequately acknowledged. The project is now completed and has been superbly prepared by Chapman & Hall.

Abstract: There are many excellent books on general statistical methods in agricul­ tural and biological research. These books cover a broad range of methods without going into detail on specialized topics. A number of topics including regression analysis, design of experiments, biological assay and categorical analysis have received in-depth treatment in specialized texts. Little appears in standard textbooks on experiments in which observations form sequences. The live weights of animals during a long-term experiment provide a familiar example of data forming a sequence, but many others occur: for example, moisture content of segments of soil cores, successive counts of insects in an orchard and hormone levels in blood over a period. Correla­ tions are likely to be found among the observations in all these examples. The book by Goldstein (1979) provided the first systematic coverage of the principles involved in longitudinal studies, but is mainly concerned with observational studies on humans. The main aims of this book are to provide research workers with methods of analysing data from comparative experiments with sequential obser­ vations and to demonstrate special features of the design of such experi­ ments. These aims are achieved by working through sets of data.

Abstract: Analysis of reliability and risk is an important and integral part of planning, construction and operation of all technical systems. To be able to perform such analyses systematically and scientifically, there is usually a need for special methods and models. This book presents the most important of these. Particular emphasis has been placed on the ideas and the motivation for the use of the various methods and models. It has been an objective to compile a book which provides practising engineers and engineering graduates with the concepts and basic techniques for evaluating reliability and risk. It is hoped that the material presented will make them so familiar with the subject that they can carry out various types of analyses themselves and understand and make use of the more detailed applications and additional material which is available in the journals and publications associated with their own discipline. It has also been an objective to put reliability and risk analyses in context - how such analyses should be used in design and operation of components and systems. The material presented is modern and a large part of the book is at research level. The book focuses on analysis of repairable systems, not only non-repairable systems which have traditionally been given most attention in textbooks on reliability theory. Since most real-life systems are repairable, methods for analysing repairable systems are an important area of research. The book presents general methods, with most applications taken from offshore petro­ leum activities.

Abstract: It would be difficult to imagine a more appropriate means of marking the Jubilee of the Dairy Research Laboratory, Division of Food Processing, CSIRO, than a publication on whey and lactose processing. The genesis of the Laboratory in 1939 was when the Australian dairy industry was very largely based on the supply of cream from farms to numerous butter factories, the skim milk being fed to pigs. By the mid-1940s, when Geof­ frey Loftus-Hills was appointed in charge ofthe fledgling Dairy Research Section, the main objective of the Section-the full utilization of the con­ stituents of milk for human food-had been firmly established. Over the next two decades progress towards this objective was exemplified by the scientific and technological contributions made in specialized milk powders for use in recombining and in the manufacture of casein and cheese. Meanwhile farming practices changed from cream production to the supply of refrigerated whole milk to the factories. By the late 1960s the increasing production of cheese and casein had re­ sulted in almost 2 million tonnes of whey per annum. This represented not only a waste disposal problem, but also under-utilization of over 100000 t of milk solids. The Laboratory had now grown to a staff of around 70, so it was possible to allocate some resources to this extra challenge.

Abstract: Most politicians have jumped on the conservation bandwagon, and nobody running for public office these days can afford to take an overtly anti­ environment stand. The fascination that children have for nature, the gen­ erous donations people make to conservation organizations, the votes cast for 'Green Parties,' the continuing popularity of zoos and wildlife films, and the strong sales of books about the environment all provide evidence to politicians that the general public supports the idea of conservation. Conservation has become a major issue for governments. No longer is it necessary for conservationists to campaign for getting the cause on the agenda: it is already there, at least as a talking point. The issue now is how to convert this generalized interest into real action. And among the many priorities competing for attention, how is a govern­ ment (or a private organization) to decide wh at to do first? From a very limited budget - for budgets will always be limited - what is the package of activities that is most likely to lead to the results that the public wants? lan Spellerberg attempts to address these questions which are at the he art of modern conservation action. It is relatively easy to prescribe useful activities that will benefit both the environment and the public at large.

Abstract: At the time that we decided to begin work on this book, several other volumes on the free-electron laser had either been published or were in press. The earliest work of which we were aware was published in 1985 by Dr T. C. Marshall of Columbia University [1]. This book dealt with the full range of research on free-electron lasers, including an overview of the extant experiments. However, the field has matured a great deal since that time and, in our judgement, the time was ripe for a more extensive work which includes the most recent advances in the field. The fundamental work in this field has largely been approached from two distinct and, unfortunately, separate viewpoints. On the one hand, free-electron lasers at sub-millimetre and longer wavelengths driven by low-energy and high-current electron beams have been pursued by the plasma physics and microwave tube communities. This work has confined itself largely to the high-gain regimes in which collective effects may play an important role. On the other hand, short-wavelength free-electron lasers in the infrared and optical regimes have been pursued by the accelerator and laser physics community. Due to the high-energy and low-current electron beams appropriate to this spectral range, these experiments have operated largely in the low-gain single-particle regimes. The most recent books published on the free-electron laser by Dr C. A.

Our thanks go to all those who, since the fifth edition, have helped in this revision by suggestions. In particular the authors express their gratitude to Jane M. Jerrard who, with enthusiasm, put the text into a computer and eliminated the editorial scissors and paste and simplified the onerous and long task of producing a text from the fragmented material of the revision. In the preface to the fifth edition it was suggested that the book provided at that time the most complete and up-to-date information of its kind available. The authors again make the same claim for this sixth edition. H. G. JERRARD D. B. McNEILL Warsash Newtownards Southampton Northern Ireland England Preface to the first edition The intense specialization that occurs in science today has meant that scientists working in one field are often not familiar with the nomenclature used by their colleagues in other fields. This is particularly so in physics. This dictionary is designed to help overcome this difficulty by giving information about the units, dimensionless numbers and scales which have been used, or are still being used, throughout the world. Some four hundred entries are provided and these are supplemented by about five hundred references. The definition of each entry is given together with relevant historical facts.

Abstract: ENVIRONMENTAL MANAGEMENT SERIES The current expansion of both public and scientific interest in environ­ mental issues has not been accompanied by a commensurate production of adequate books, and those which are available are widely variable in approach and depth. The Environmental Management Series has been established with a view to co-ordinating a series of volumes dealing with each topic within the field in some depth. It is hoped that this Series will provide a uniform and quality coverage and that, over a period of years, it will build up to form a library of reference books covering most of the major topics within this diverse field. It is envisaged that the books will be of single, or dual authorship, or edited volumes as appropriate for respective topics. The level of presentation will be advanced, the books being aimed primarily at a research/consultancy readership. The coverage will include all aspects of environmental science and engineering pertinent to manage­ ment and monitoring of the natural and man-modified environment, as well as topics dealing with the political. t:conomic, legal and social con­ siderations pertaining to environmental management.

Abstract: A technological book is written and published for one of two reasons: it either renders some other book in the same field obsolete or breaks new ground in the sense that a gap is filled. The present book aims to do the latter. On my return from industry to an academic career, I started writing this book because I had seen that a gap existed. Although a great deal of information appeared in the published literature about various technical aspects of advanced manufacturing technology (AMT), surprisingly little had been written about the systems con­ text within which the sophisticated hardware and software of AMT are utilized to increase efficiency. Therefore, I have attempted in this book to show how structured approaches in the design and evaluation of modern manufacturing plant may be adopted, with the objective of improving the performance of the factory as a whole. I hope this book will be a contribution to the newly recognized, multidisciplinary engineering function known as manufacturing sys­ tems engineering. The text has been designed specifically to demonstrate the systems aspects of modern manufacturing operations, including: systems con­ cepts of manufacturing operation; manufacturing systems modelling and evalua­ tion; and the structured design of manufacturing systems~ One of the major difficulties associated with writing a text of this nature stems from the diversity of the topics involved. I have attempted to solve this problem by adopting an overall framework into which the relevant topics are fitted.

Abstract: This second edition of Satellite Communications is a revised, updated, and improved version of the first edition (Van Nostrand, 1984) and has been extended to include many newer topics that are rapidly becoming important in modem and next-generation satellite systems. The first half of the book again covers the basics of satellite links, but has been updated to include additional areas such as Global Positioning and deep space satellites, dual polarization, multiple beaming, advanced satellite electronics, frequency synthesizers, and digital frequency generators. The second half of the book is all new, covering frequency and beam hopping, on-board processing, EHF and optical cross­ links, and mobile satellites and VSAT systems. All of these latter topics figure to be important aspects of satellite systems and space platforms of the twenty-first century. As in the first edition, the objective of the new edition is to present a unified approach to satellite communications, helping the reader to become familiar with the terminology, models, analysis procedures, and evolving design directions for modem and future satellites. The presentation stresses overall system analysis and block diagram design, as opposed to complicated mathematical or physics descriptions. (Backup mathematics is relegated to the appendices where a reader can digest the detail at his own pace. ) The discussion begins with the simplest satellite systems and builds to the more complex payloads presently being used.

Abstract: This book contains the fundamentals of a discipline, which could be called Structural Analysis in Microelectronics and Fiber Optics. It deals with mechanical behavior of microelectronic and fiber-optic systems and is written in response to the crucial need for a textbook for a first in-depth course on mechanical problems in microelectronics and fiber optics. The emphasis of this book is on electronic and optical packaging problems, and analytical modeling. This book is apparently the first attempt to select, advance, and present those methods of classical structural mechanics which have been or can be applied in various stress-strain problems encountered in "high technology" engineering and some related areas, such as materials science and solid-state physics. The following major objectives are pursued in Structural Analysis in Microelectronic and Fiber-Optic Systems: Identify structural elements typical for microelectronic and fiber-optic systems and devices, and introduce the student to the basic concepts of the mechanical behavior of microelectronic and fiber-optic struc­ tures, subjected to thermally induced or external loading. Select, advance, and present methods for analyzing stresses and deflections developed in microelectronic and fiber-optic structures; demonstrate the effectiveness of the methods and approaches of the classical struc­ tural analysis in the diverse mechanical problems of microelectronics and fiber optics; and give students of engineering, as well as practicing engineers and designers, a thorough understanding of the main princi­ ples involved in the analytical evaluation of the mechanical behavior of microelectronic and fiber-optic systems.

Abstract: The impetus to create this book originated from several concerns. One of these was the perceived value to the industry of a collection in one volume of a wide range of information pertinent to the reasons and techniques for de fluxing printed wiring assemblies (PWAs). This book is expected to be of use not only to those engaged in the electronics packaging industry but also to those in related fields seeking information concerning viable methods of dealing with one of the en­ vironmental issues of our time: the destruction of the ozone layer surrounding and protecting the planet with which we have been entrusted. The volume of information relative to providing PW As free of residues ad­ versely impacting operation, reliability, and life of electronic products is grow­ ing, and it will continue to expand at an accelerated rate as we seek to match our technology needs and desires with our environmental responsibilities. At the time ofthis writing, which has spanned the latter portion of 1989 and early 1990, the issue of choosing a new approach to producing PW As free of detrimental residues while using environmentally acceptable manufacturing techniques ap­ peared to be the major concern of the vast majority of those involved in the printed wiring assembly industry. To many this meant the use of different clean­ ing media and/or process or equipment enhancements; to others it meant the elimination of the need to clean through materials or process changes.

Numerous government, academic, interest group, and media reports questioning the adequacy of the food safety regulatory system formed the basis for this increase in concern. While public concern focused most directly on pesticide residues in food, scientists emphasized the risks of illness associated with microbiological contamination of food. Much additional attention was focused on the food supply as a result of the striking consensus on dietary recommendations that emerged in the late 1980s based on increased scientific knowledge of linkages between diet and health. Relatively little research on the economic aspects of food safety and nutrition issues had been conducted up to the mid-1980s. These aspects are complex. On the consumer demand side, they include consumers' perceptions of the risks associated with particular food products, how demographic characteristics influence consumers' processing of risk information and subsequent changes in food demand behavior, and the monetary value consumers might place on changes in the risk profiles of products. The economic benefits and costs associated with current food consumption patterns are a major determinant of demand for improved food safety and dietary change through government regulation. While a more complete picture of risks, benefits, and costs has been emerging recently, much is yet unknown.

Abstract: The most critical part of the modern switching-mode power supply is the regulated dc/dc converter. Its dynamic behavior directly determines or influences four of the important characteristics of the power supply: • Stability of the feedback loop • Rejection of input-voltage ripple and the closely-related transient re­ sponse to input-voltage perturbation • Output impedance and the closely-related transient response to load perturbation • Compatibility with the input EMI filter Due to the complexity of the operation of the converter, predicting its dynamic behavior has not been easy. Without accurate prediction, and depending only on building the circuit and tinkering with it until the operation is satisfactory, the engineering cost can easily escalate and schedules can be missed. The situation is not much better when the circuit is built in the computer, using a general-purpose circuit-simulation program such as SPICE. (At the end of this book is a form for obtaining information on a computer program especially well suited for dynamic analysis of switching-mode power converters: DYANA, an acronym for "DYnamic ANAlysis. " DYANA is based on the method given in this book. ) The main goal of this book is to help the power-supply designer in the prediction of the dynamic behavior by providing user-friendly analytical tools, concrete results of already-made analyses, tabulated for easy application by the reader, and examples of how to apply the tools provided in the book.

Abstract: The sequence of events which led to the writing of this book started at a seminar on Manufacturing Technology in the Electronics Industry given by the Institution of Production Engineers in 1987. The seminar identified that the field of manufacturing engineering for the electronics industry was effectively missing from the vast majority of production engineering degree courses. The reason for this was that production engineering departments typically spring from mechanical engineering departments. This leads to a mechanical bias in the practical aspects of such courses. The consequence of this was that electronics companies could not recruit graduates with both relevant production engineering and electronic engineering backgrounds. This necessitated either recruiting production engineering graduates and giving them the necessary electronic engineering training, or giving production engineering training to electronic engineering graduates. A consequence of the lack of courses in a subject is that there is also a lack of relevant textbooks in the area, as most textbooks are intended to tie into courses. In the field of manufacturing technology for the electronics industry, existing textbooks tend to be highly specialized and mainly concerned with the fabrication of semiconductor devices.

Abstract: During the Inaugural Meeting of the European Association of Acarol­ ogists (EURAAC), held in Amsterdam in 1987, it was decided that the holding of a Symposium at regular intervals should be a major objective. With this in view, it was agreed that Professor Reinhart Schuster, the senior editor, be invited to accept the Presidency of the Association and, arising from that Office, to organize the first Symposium in Austria in 1988. There was strong support for a main theme focused on a particular aspect of acarology. From these discussions there emerged the proposal that emphasis be placed on aspects of reproduction, development and life-history strategies of the Acari. These were topics in the forefront of the discipline with exciting developments of interest not only to acarologists but to a wider audience because of the light they cast on fundamental processes in physiology, ecology and evolutionary biology. The object then was to invite a small number of key workers to present extended papers related to the main theme. There were seven of these all of which appear in the book. The remaining 51 contributions were offered papers a number of which fit within the framework of the Symposium theme.

Abstract: The purpose of this technical seminar was to evaluate the present state of the art in matter of advanced separation techniques like solvent extraction, ion-exchange, chemical precipitation, membrane and electrical processes for the treatment of radioactive liquid waste and a selection of some specific industrial non-radioactive effluents. Through this initiative, the organisers aimed at promoting the exchange of information between scientists from various origins (universities, research centres and industries) while contributing to the necessary overcoming of the artificial barriers which too often limit the "technology transfer" between the nuclear and non-nuclear sectors.

Abstract: The central theme of this book is that systems of cell-cell signalling via nerves, hormones, local mediators and growth factors are not distinct phenomena, but branches of one general mechanism. These topics therefore can and should be discussed in an integrated manner, and the division of cell signalling studies into separate pigeonholes such as neuroscience, endocrinology or cancer biology is unnecessary, if not counterproductive. I also believe it to be unfortunate that there is not a collective term to describe neurotransmitters, hormones, local mediators and growth factors, other than clumsy phrases such as "extracellular signal molecule". The lack of a short and distinctive word for these entities genuinely hampers people from thinking about them in an integrated way. Having decided that it was presumptuous to invent a new term, I have chosen in this book the term first messenger to cover all types of extracellular signal molecule, because of the widespread acceptance of the term second messenger to represent the intracellular signal molecules that are produced in response to many of them. I have given the book the title "biochemical messengers", which is a global term to cover both first and second messengers. The impetus for writing the book came, as must often be the case, when I had to put together a course on cell-cell signalling for biochemistry students at the University of Dundee.

Abstract: In writing this book, our goal was to produce a much needed teaching and reference text with a fresh approach to c1eanroom technology. The most obvious technological reason for bringing this book into being is that c1ean­ rooms have become vital to the manufacture and development of high­ technology products in both the commercial and military sectors, and there­ fore people have to develop an understanding of them. Examples of c1ean­ room applications include the manufacture of integrated circuits and other electronic components, preciSion mechanical assemblies, computer disks and drives, compact disks, optical components, medical implants and prostheses, pharmaceuticals and biochemicals, and so on. The book is written for anyone who is currently involved, or intends to become involved, with c1eanrooms. We intend it to be used by a wide range of professional groups including process engineers, production engineers, plant mechanical and electrical engineers, research engineers and scientists, managers, and so on. In addition, we believe it will be beneficial to those who design, build, service, and supply c1eanrooms, and may be used as a training aid for students who intend to pursue a career involving controlled environments and others such as c1eanroom operators and maintenance staff. We have attempted to steer clear of complex theory, which may be pursued in many other specialist texts, and keep the book as understandable and applicable as possible.

Abstract: Blood-sucking insects are the vectors of many of the most debilitating parasites of man and his domesticated animals. In addition they are of considerable direct cost to the agricultural industry through losses in milk and meat yields, and through damage to hides and wool, etc. So, not surprisingly, many books of medical and veterinary entomology have been written. Most of these texts are organized taxonomically giving the details of the life-cycles, bionomics, relationship to disease and economic importance of each of the insect groups in turn. I have taken a different approach. This book is topic led and aims to discuss the biological themes which are common in the lives of blood-sucking insects. To do this I have concentrated on those aspects of the biology of these fascinating insects which have been clearly modified in some way to suit the blood-sucking habit. For example, I have discussed feeding and digestion in some detail because feeding on blood presents insects with special problems, but I have not discussed respiration because it is not affected in any particular way by haematophagy. Naturally there is a subjective element in the choice of topics for discussion and the weight given to each. I hope that I have not let my enthusiasm for particular subjects get the better of me on too many occasions and that the subject material achieves an overall balance.

Abstract: Although aspects of mineral deposit evaluation advantages and disadvantages of each technique are covered in such texts as McKinstry (1948), so that a judgement can be made as to their Peters (1978), Reedman (1979) and Barnes applicability to a particular deposit and the min­ (1980), no widely available in-depth treatment of ing method proposed or used. Too often, a lack the subject has been presented. It is thus the of this expertise results in the ore-reserve calcula­ intention of the present book to produce a text tion being undertaken at head-office or, indeed, by the survey department on the mine, and being which is suitable for both undergraduate and treated as a 'number crunching' or geometric postgraduate students of mining geology and exercise divorced from geology. It is essential mining engineering and which, at the same time, that mine ore-reserves are calculated at the mine is of use to those already following a professional by those geologists who are most closely associ­ career in the mining industry. An attempt has ated with the local geology and who are thus best been made to present the material in such a way able to influence and/or constrain the calculation.

Abstract: Citrus juices constitute the majority of the fruit juices consumed in the United States and around the world. Along with the rest of the fruit juice industry, they playa major role in the entire food industry as well. In spite of this prominence, few texts have been written on quality control technology; and most of the texts have been written by researchers who may possess great technical skill but generally are less familiar with daily routine quality control problems and con­ cerns than quality control technologists are. On the other hand, quality control technologists and managers generally do not have the time and/or the talent to write books or communicate through scientific literature. The author recognized the need for an updated, comprehensive, and easily understood text on citrus quality control. This text has been designed to be used not only by processors, bottlers, canners, and others involved in the citrus in­ dustry, but it can be of value to instructors and students of citrus technology.

Abstract: It is 25 years since Dr Burgess wrote his invaluable book on hops and in the intervening period there have been very many advances in hop research and hop production techniques. When invited to produce a replacement for that book, therefore, the problem was not finding enough new material but deciding on what to include. People interested in reading about the hop are likely to fall into very diverse categories. Hop growers will be looking for practical advice on production methods while research workers with specialist knowledge in one field may want detailed information about research in other disciplines. In addition, there are many people for whom hops are of much more general interest and for them a source of basic information about the crop will be required. The aim has not been to produce a detailed growers' handbook, since techniques vary considerably from district to district and I believe that it is better to obtain advice from neighbouring growers or from specialist advisers than from any book. What I have attempted is to outline the basic principles upon which production methods should be based. At the same time, I have tried to include material that will be of general interest both to those who work with hops and to those to whom they might otherwise remain a complete mystery. In doing this my own personal interests have inevitably played an important part.

Abstract: After many years of teaching circuit theory and analogue electronic circuits the author believes that for most students the main path to obtaining a good understanding of the principles involved, as measured by their ability to apply them in a correct and intelligent manner, is through problem solving and design exercises. In an ideal world the student would be able to construct the circuit being analysed or designed, and so directly test the calculated or pre­ dicted results. Indeed, experience leads to the conclusion that typical students like to see their own circuits perform as intended, with a con­ sequent increase in motivation. At present, however, time and facility constraints mean that most of this work is of the pencil and paper variety, students having few opportunities to see the consequences of their efforts in a practical situation. At best they have to accept sample solutions or simply num­ erical answers. This path can seem tedious to all but the most motivated of students, so an alternative which can provide many of the benefits of direct circuit testing within the time and resources available is of im­ mediate interest. This is where the MINNIE and HSpice simulation package can assist the undergraduate teaching activity.

Abstract: As the developments in engineering production techniques have resulted in an increasing dependence on automation, the increasing complexity of these systems has made the reliability of the machines a matter of great importance. An unexpected breakdown can be a very expensive experience for the company. Further, in the aerospace industry, problems of reliability, maintainability and availability are critical. For a long time industrial research and training centres have been interested primarily in the problems of design, manufacture and production; recently, however, there has been a growing interest in the study of maintenance and reliability. The concept of maintainability, for example, first appeared in 1954 in the US army. Since then a variety of techniques and methodologies have been developed and implemented to meet the challenge of the new needs. The aim of this book is to present these methods and investigate their effectiveness, and in so doing to help practising engineers gain a better understanding of the problems. The many examples and applications given here should make it a valuable teaching aid to students taking courses in engineering maintenance. This second edition has been revised and enlarged to take account of the most recent developments and illustrate their application to the solution of problems. It should also help to orient the reader to the modern concept of computer-aided maintenance. Introduction A maintenance service exists to keep equipment in running order and also to reduce the number of breakdowns.

Abstract: Plastics are part of everyday life and contribute immensely to the benefit of humanity. When failures occur, they are due in part either to inferior properties (resulting from poor design or badly controlled processing), or to an incomplete understanding of the properties and applications of plastics materials. Since publication of the first edition, the plastics industry has increas­ ingly adopted advanced business procedures and automation (such as closed loop control and robotics), to combat the effects of recession, and has moved increasingly towards methods based on sound scientific and technological principles. Plastics have increasingly been used in appli­ cations once dominated by the use of metals and ceramics. For instance, in the automotive industry, the modern car now contains a much higher proportion of polymers, including commodity plastics and more spec­ ialized materials. In addition, compact discs are being made from new injection-moulding grades of polycarbonate, which meet the requirements of a demanding process. This second edition has been thoroughly revised and extended to include new materials, technologies and design concepts. Chapters on thermoplastics reflect the development of polymer blends and alloys, whilst the chapters devoted to thermosets have been reorganized to accommodate the renaissance in the applications of phenolics and to cover the growing importance of polyurethanes. The related two­ component process technologies are now included; having undergone major developments in the last decade, they have become important shaping processes.

Abstract: Life has shaped the Earth, and the Earth has moulded the history of life. That history, the co-evolution of our ancestors and their horne, has much to teach us about our place on the planet today. We are part of the fabric of the biosphere. As we change that fabric we would be wise to understand how our horne was built. Our planet is neither a hotel nor a colony. It is not a place which life briefly inhabits during a transient occupation. Instead, it is our horne, designed by the deeds of our ancestors and suited to our own needs. The history of life on Earth is held in the geological record, which is composed of the rocks, water and air that are available for study on the planet's surface. These rocks, the oceans and the atmosphere are not simply stores of information for the excitement of fossil hunters and geochemists, or resources to exploit without thought. Their cre­ ation and continued existence form an integral part of the development and management of the Earth as the horne of life.

Abstract: Marketing communications is a subject which has become popular in both marketing and public relations circles, but sometimes with different parameters. There are those who prefer to confine marketing communications to promotional activities, which is mostly an academic point of view, and there are those who see the subject in broader terms, embracing every form of communication used in marketing, which is how the subject is practised in the business world. While the author has long experience as a teacher and examiner, he also continues to be a professional practitioner. Consequently, the book aims to serve those concerned with both the academic and the professional in terpreta tions of marketing comm unica tions. I t is of course hoped that those who adopt the academic approach to the subject will eventually acknowledge that there is more to marketing communi­ cations than advertising, sales promotion, selling, marketing research and public relations. It is also necessary to realise that public relations embraces much more than the 'publicity' in the 4Ps promotion box. Without wishing to be contentious, this broad approach is proposed so that communications of all kinds throughout the marketing strategy can have maximum effect. Very little has been published on this subject, and the book is therefore a pioneer attempt to establish the practical parameters of modern marketing communications. There are so many broad and narrow interpretations of marketing communications, but it is hoped that this book will be useful to teachers, students and practitioners of the subject.

Abstract: This book is the second edition of Design to Test. The first edition, written by myself and H. Frank Binnendyk and first published in 1982, has undergone several printings and become a standard in many companies, even in some countries. Both Frank and I are very proud of the success that our customers have had in utilizing the information, all of it still applicable to today's electronic designs. But six years is a long time in any technology field. I therefore felt it was time to write a new edition. This new edition, while retaining the basic testability prin­ ciples first documented six years ago, contains the latest material on state-of-the-art testability techniques for electronic devices, boards, and systems and has been completely rewritten and up­ dated. Chapter 15 from the first edition has been converted to an appendix. Chapter 6 has been expanded to cover the latest tech­ nology devices. Chapter 1 has been revised, and several examples throughout the book have been revised and updated. But some­ times the more things change, the more they stay the same. All of the guidelines and information presented in this book deal with the three basic testability principles-partitioning, control, and visibility. They have not changed in years. But many people have gotten smarter about how to implement those three basic test­ ability principles, and it is the aim of this text to enlighten the reader regarding those new (and old) testability implementation techniques.

Abstract: Yeasts are the active agents responsible for three of our most important foods - bread, wine, and beer - and for the almost universally used mind/ personality-altering drug, ethanol. Anthropologists have suggested that it was the production of ethanol that motivated primitive people to settle down and become farmers. The Earth is thought to be about 4. 5 billion years old. Fossil microorganisms have been found in Earth rock 3. 3 to 3. 5 billion years old. Microbes have been on Earth for that length of time carrying out their principal task of recycling organic matter as they still do today. Yeasts have most likely been on Earth for at least 2 billion years before humans arrived, and they playa key role in the conversion of sugars to alcohol and carbon dioxide. Early humans had no concept of either microorganisms or fermentation, yet the earliest historical records indicate that by 6000 B. C. they knew how to make bread, beer, and wine. Earliest humans were foragers who col­ lected and ate leaves, tubers, fruits, berries, nuts, and cereal seeds most of the day much as apes do today in the wild. Crushed fruits readily undergo natural fermentation by indigenous yeasts, and moist seeds germinate and develop amylases that produce fermentable sugars. Honey, the first con­ centrated sweet known to humans, also spontaneously ferments to alcohol if it is by chance diluted with rainwater. Thus, yeasts and other microbes have had a long history of 2 to 3.

Abstract: The last twenty years or so have seen a flurry of activity in the synthesis of new polymer systems. This interest has developed largely as a result of the increased need for advanced materials. Despite the emergence of a number of outstanding polymers, it is the polyimides that have captured the imagination of scientists and engineers alike as materials that offer outstanding promise for the high technology applic­ ations of the future. The reputation of the polyimide has been established on the bases of outstanding thermal stability, excellent mechanical properties and the ability to be fabricated into useful articles. Polyimides offer a versatility unparalleled in most other classes of macromolecules. Polymers can be prepared from a variety of starting materials, by a variety of synthetic routes. They can be tailor-made to suit specific applications. By judicious choice of starting materials, polymers can be made that offer variations in such properties as glass transition tempera­ ture, oxidative stability, toughness, adhesion, and permeability. It is this versatility that has led to the use of polyimides in a wide variety of applications. The electronics industry makes extensive use of poly imide films in, ior example, semiconductor applications. The leading polymer matrices for high temperature advanced composites are polyimides. High temperature adhesive systems for the bonding of metals or composites are often based on polyimides. In addition, polyimides are now finding use as fibres, foams, sealents and even membranes for the low energy separation of industrial gases.

Abstract: A question often asked of those of us who work in the seemingly esoteric field of fish vision is, why? To some of us the answer seems obvious - how many other visual scientists get to dive in a tropical lagoon in the name of science and then are able to eat their subjects for dinner? However, there are better, or at least scientifically more acceptable, reasons for working on the visual system of fish. First, in terms of numbers, fish are by far the most important of all vertebrate classes, probably accounting for over half (c. 22 000 species) of all recognized vertebrate species (Nelson, 1984). Furthermore, many of these are of commercial importance. Secondly, if one of the research aims is to understand the human visual system, animals such as fish can tell us a great deal, since in many ways their visual systems, and specifically their eyes, are similar to our own. This is fortunate, since there are several techniques, such as intracellular retinal recording, which are vital to our understanding of the visual process, that cannot be performed routinely on primates. The cold­ blooded fish, on the other hand, is an ideal subject for such studies and much of what we know about, for example, the fundamentals of information processing in the retina is based on work carried out on fish (e. g. Svaetichin, 1953).

Abstract: The third International Conference on Composite Interfaces (ICCI-III) was held under the auspecies of ASM International, The Aluminum Company of America (Alcoa), The Edison Polymer Innovation Co. (EPIC), Case Western Reserve University, Nippon Glass Fiber Co., Nitto Boseki Co., Office of Naval Reserach (ONR), SAMPE Japan, Teijin Co., Mobay Co., Union Carbide Co., and Vetrotex Sain-Gobain. The underlying philosophy of the conference continues to be the promotion of fundamental understanding of the structure and role of composite interfaces. With the growth of composite interface studies, the research direction naturally changes from characterization and understanding of interfacial structure to controlling this structure. For this reason, the conference was subtitled, "Controlled Interphase Structure." The rather unfamiliar phrase "interphase" is used to emphasize the interfacial region whose properties are different from the bulk. The importance of the interphase to the mechanochemical properties has been rapidly recognized among composite researchers in recent years. The conference incorporated nine sessions. No concurrent sessions were planned because of the strong interest among panicipants and organizers to intennix researchers from different disciplines. Papers presented were redistributed in Pans I throught V. Because of this, both the conference and proceedings are not organized based on the traditional disciplines or materials, but rather around concepts.

Abstract: Landscapes viewed from afar have a timeless quality that is soothing to the human spirit. Yet a tranquil wilderness scene is but a snapshot in the steady stream of surficial change. Wind, water and human activities reshape the landscape by means of gradual to catastrophic and usually irreversible events. Much of this change destroys past landscapes, but at some times and places, landscapes are buried in the rock record. This work is dedicated to the discovery of past landscapes and their life through the fossil record of soils. A long history of surficial changes extending back almost to the origin of our planet can be deciphered from the study of these buried soils, or paleosols. Some rudiments of this history, and our place in it, are outlined in a final section of this book. But first it is necessary to learn something of the language of soils, of what happens to them when buried in the rock record and which of the forces of nature can be confidently reconstructed from their remains. Much of this preliminary material is borrowed from soil science, but throughout emphasis is laid on features that provide most reliable evidence of landscapes during the distant geological past. This book has evolved primarily as a text for senior level university courses in paleopedology: the study of fossil soils.

Abstract: This book originated from my Publisher's request for anew, concise account of PVC plastics in terms of their nature, properties, process­ ing, and applications. There is thus, inevitably, an extensive thematic overlap with my-still relatively recent-PVC Technology (4th edi­ tion), and I have drawn liberally on that source for a substantial amount of relevant basic material. However, the present book is by no means merely an abridgement of the earlier one: whilst indeed considerably shorter, it is not only comparable in scope and general coverage of the subject, but also contains much new information. I have made a point of again strongly featuring the numerous standards relevant-and in many cases cardinal-to the testing and characterisa­ tion of PVC materials and products, and to the evaluation of their properties and performance: these standards are an indispensable part of the technology of PVC plastics, and nobody concerned with any aspect of this complex subject should fail to recognise that fact. It is ever a pleasure to express appreciation and thanks where they are due. I am grateful to Dipl-Ing. H. E. Luben of Brabender OHG, Duisburg, FRG, not only for the up-to-date information he provided on Brabender equipment, but also most particularly for his exception­ ally friendly, helpful attitude in all our contacts, and for the trouble he took to make some illustrations and figures available in the form convenient for direct reproduction.

Abstract: This book presents a circumspective overview and update of the present existing knowledge of the biology, chemistry and pathophysiology of the dental pulp. It details numerous observations of a group of highly specialized investigators who have united in the common purpose of presenting their observations for the benefit of clinicians, teachers, researchers and students. Fortunately, the dental literature presents abundant research findings about pulp biology and the pulp's responses to various stimuli. This abundance has resulted in an increased interest and expansion of research on this subject. For example, publications abound on the response of pulp tissue to various medications and to a variety of types of dental materials which may be placed near to or at some distance from the pulp through the medium of dentine. One of the reasons the pulp is of such interest is that it not only provides the vitality to the teeth but also produces the dentine - both the primary and secondary, as well as reparative. The latter-type dentine is a result of the pulp's functions in response to disease as the former dentine is in response to health. As an example, some investigators have reported the effects of cutting of dentine and the placement of restorations in dentine which in turn reflect changes on the pulp tissue. These reports have raised a number of questions, which in turn have created a need for answers.

Abstract: One of the most exciting prospects for optical fibres made from fluoride glasses is the possibility of providing long distance optical communication systems without the need for repeaters. This objective has stimulated much of the work into fluoride glasses over the past ten years, and has prompted the writing of this book. It has also emerged that fluoride fibres can transmit both visible and infrared energy (from about 0.5 to 5 ,urn) and that they have many applications outside the field of telecommunications. These include optical fibre sensors (particularly in remote infrared spectroscopy), laser surgery and fibre lasers. Several companies are now established in the field, and good quality fluoride fibres are available from sources throughout the USA, Europe and Japan. Moreover, the first commercial instruments based on fluoride fibres are finding their way to the market place and these fibres will undoubtedly form the basis of many more instruments yet to be developed. The work presented in this book represents the field both from an academic understanding of the materials and ways to convert them into fibre, and from a practical and commercial viewpoint. The principal author and some of the co­ authors are based at the British Telecom Research Laboratories in the UK.

Abstract: The Handbook of Electronics Packaging Design and Engineering has been writ­ ten as a reference source for use in the packaging design of electronics equip­ ment. It is designed to provide a single convenient source for the solution of re­ curring design problems. The primary consideration of any design is that the end product meet or exceed the applicable product specifications. The judicious use of uniform design practices will realize the following economies and equipment improvements: • Economics of design. Uniform design practices will result in less engineering and design times and lower costs. They will also reduce the number of changes that may be required due to poor reliability, maintainability, or producibility. • Improved design. Better designs with increased reliability, maintainability, and producibility will result from the use of uniform design practices. • Production economies. Uniform designs employing standard available tools, materials, and parts will result in the cost control of manufacturing. The Handbook is intended primarily for the serious student of electronics packaging and for those engineers and designers actively engaged in this vital and interesting profession. It attempts to present electronics packaging as it is today. It can be used as a training text for instructional purposes and as a reference source for the practicing designer and engineer.

Abstract: We first discussed the possibility of organizing a symposium on helminth communities in June, 1986. At that time, we were engaged in writing a joint paper on potential structuring mechanisms in helminth communities; we disagreed on a number of issues. We felt the reason for such debate was because the discipline was in a great state of flux, with many new concepts and approaches being introduced with increasing frequency. After consider­ able discussion about the need, scope and the inevitable limitations of such a symposium, we decided that the time was ripe to bring other ecologists, engaged in similar research, face-to-face. There were many individuals from whom to choose; we selected those who were actively publishing on helminth communities or those who had expertise in areas which we felt were particularly appropriate. We compiled a list of potential participants, contacted them and received unanimous support to organize such a symposium. Our intent was to cover several broad areas, fully recognizing that breadth negates depth (at least with a publisher's limitation on the number of pages). We felt it important to consider patterns amongst different kinds of hosts because this is where we had disagreed among ourselves.

Abstract: Planar Processing Primer is based on lecture notes for a silicon planar process­ ing lecture/lab course offered at the University of Illinois-UC for over fifteen years. Directed primarily to electrical engineering upperclassmen and graduate students, the material also has been used successfully by graduate students in physics and ceramic and metallurgical engineering. It is suitable for self-study by engineers trained in other disciplines who are beginning work in the semiconductor fields, and it can make circuit design engineers aware of the processing limitations under which they must work. The text describes and explains, at an introductory level, the principal processing steps used to convert raw silicon into a semiconductor device or integrated circuit. First-order models are used for theoretical treatments (e.g., of diffusion and ion implantation), with reference made to more advanced treatments, to computer programs such as SUPREM that include higher order effects, and to interactions among sequential processes. In Chapters 8, 9, and to, the application of silicon processes to compound semiconductors is discussed briefly. Over the past several years, the size of transistors has decreased markedly, allowing more transistors per chip unit area, and chip size has increased.

Abstract: This book is intended to be a companion volume to 'Protein Nutrition in Ruminants' (1982, Academic Press), which emphasized both the role of proteins and new systems for their evaluation. Here the focus is on energy-yielding nutrients and problems involved in evaluating them. Nonetheless in both volumes there is explicit recognition of the interdependence of energy and protein nutrition. I have not attempted to review comprehensively all the literature relating to ruminant energy nutrition and must apologize to colleagues whose work is not fully reported. Where possible tables and figures are taken from the studies of our group at the Rowett Research Institute since, if for no other reason, I am most familiar with these data. I have first considered the nutrition of the newborn and have stressed the role of behaviour 'in determining whether nutrients enter or bypass the rumen. The development of the rumen, the of anaerobic fermentation and the roles of various principles . species of rumen bacteria, protozoa and fungi in relation to different substrates, are summarized. This is followed by accounts of the factors affecting the utilization of different substrates and the v vi Preface absorption and metabolism of the end-products of fermentation and digestion, together with estimates of digestive capacity in various segments of the gut. The ruminant's requirements for energy-yielding nutrients is considered in relation to the per­ formance of various activities and to environmental conditions, particular attention being paid to the requirement for glucose precursors.

Abstract: The main aim of this book is to present a broader view of scientific software than has been common in the past. The provision of scientific software is no longer a matter of just writing 'good computer programs', but rather it is concerned with the development of an integrated software system wI-,ich offers the user facilities which approach all that he needs in terms of speed, accuracy and convenience. This means that due account must, for example, be taken of the high-speed computing capabilities of parallel processors, the exact computing features of symbolic mathematical systems, the presentational potentialities of computer graphics, and the advisory aspects of knowledge-based and expert systems. When suites of numerical software programs or routines are supported by such ranges of facilities, then they can be justly described as 'scientific software systems', and that is why we have adopted such a title here. The assembly of this book was a direct consequence of the running of a one-day international symposium, with the same broad aim of advocating a 'systems approach', under the title 'Scientific Software and Systems'. This Symposium was held at the Royal Military College of Science (RMCS) in Shrivenham on July 11, 1988 and was attended by 85 people. A very busy but most enjoyable day included invited talks, poster presentations and demonstrations of software products, not to mention various social activi­ ties.

Abstract: During the last two decades, the production of polymers and plastics has been increasing rapidly. In spite of developing new polymers and polymeric materials, only 40-60 are used commercially on a large scale. It has been estimated that half of the annual production of polymers is employed outdoors. Increasing the stability of polymers and plastics towards heat, light, atmospheric oxygen and other environmental agents and weathering conditions has always been a very important problem. The photochemical instability of most of polymers limits them to outdoor application, where they are photo­ degraded fast over periods ranging from months to a few years. To the despair of technologists and consumers alike, photodegrada­ tion and environmental ageing of polymers occur much faster than can be expected from knowledge collected in laboratories. In many cases, improved methods of preparation and purification of both monomers and polymers yield products of better quality and higher resistance to heat and light. However, without stabilization of polymers by applica­ tion of antioxidants (to decrease thermal oxidative degradation) and photostabilizers (to decrease photo-oxidative degradation) it would be impossible to employ polymers and plastics in everyday use.

Abstract: During the past decade there have been many changes in the perfumery industry which are not so much due to the discovery and application of new raw materials, but rather to the astronomic increase in the cost of labour required to produce them. This is reflected more particularly in the flower industry, where the cost of collecting the blossoms delivered to the factories has gone up year after year, so much so that most flowers with the possible exception of Mimosa, have reached a cost price which has compelled the perfumer to either reduce his purchases of absolutes and concretes, or alternatively to substitute them from a cheaper source, or even to discontinue their use. This development raises an important and almost insoluble problem for the perfumer, who is faced with the necessity of trying to keep unchanged the bouquet of his fragrances, and moreover, to ensure no loss of strength and diffusiveness. Of course, this problem applies more especially to the adjustment of formulae for established perfumes, because in every new creation the present high cost of raw materials receives imperative con­ sideration before the formula is approved.

Abstract: It is now fifteen years since the last edition of this reference volume appeared and during this time new materials have appeared and some have fallen into disuse. The present edition is the result of much revision and some deletion and an effort has been made to bring the information up-to-date and in conformity with current practice. Of recent years several speciality materials have appeared, and a number of these are included where their chemical composition is known. Speciality materials of vague composition are not included. For many of the compounds listed several alternative names are in use, some of which from the chemist's point of view are either inadequate, ambiguous, or occasionally actually misleading. In this edition the compounds have been listed under names which are considered to be chemically satisfactory and which, at the same time, should be reasonably familiar to perfumers; they do not necessarily contain full information as to the structure of the com­ pound and they make free use of widely accepted trivial names. In most of the entries this is followed by a systematic name which defines the chemical structure, while synonyms which are in use, though sometimes chemically unsatisfactory, are given in brackets, with a cross-reference to the main entry. Prefixes denoting structural features, such as n-, iso-, cis-, trans-, 0-, m-, p-, and so on are disregarded in the alphabetical listing.

Abstract: This book is intended as a practical manual for chemists, biologists and others whose work requires the use of pH or metal-ion buffers. Much information on buffers is scattered throughout the literature and it has been our endeavour to select data and instructions likely to be helpful in the choice of suitable buffer substances and for the preparation of appropriate solutions. For details of pH measurement and the preparation of standard acid and alkali solutions the reader is referred to a companion volume, A. Albert and E. P. Serjeant's The Determination of Ionization Constants (1971). Although the aims of the book are essentially practical, it also deals in some detail with those theoretical aspects considered most helpful to an understanding of buffer applications. We have cast our net widely to include pH buffers for particular purposes and for measurements in non-aqueous and mixed solvent systems. In recent years there has been a significant expansion in the range of available buffers, particularly for biological studies, largely in conse­ quence of the development of many zwiUerionic buffers by Good et al. (1966). These are described in Chapter 3.

Abstract: THE NATURE OF THE PROBLEM THIS book results from an attempt to explain on a basis of experimental physics some of the many strange phenomena produced by the natural movement of sand over the dry land of the Earth. The subject is but one aspect of a far wider problem which is still very imperfectly grasped-the transport of solid particles of any kind by fluids in general. Here the difficulty has been, and still is, that no one branch of science has attempted to deal with the problem as a whole, or to co-ordinate the vast amount of piecemeal work by students of different outlook in many unrelated fields. The carriage of silt by rivers has received a great deal of attention from engineers. But owing to the difficulties of direct measurement, to the expense and labour of conducting full-scale experiments, and to a failure to find agreement as to the basic quantities upon which a theoretical edifice may be built, the published results are far from satisfactory. Little has emerged except empirical formulae; and these are rarely capable of reliable application to conditions other than those under which they were evolved. The drifting of snow is of direct interest to transport authorities in many countries, to meteorologists engaged in the study of rainfall, to ski-runners and to mountaineers. Yet no means has been found whereby the precipitation can be gauged, or the rate of drift related to the strength of the wind.

Abstract: In this book we have described the major events of embryonic development and considered the underlying mechanisms which result in the production of a viable hatchling. We have, as the subtitle of the book indicates, con­ centrated on behavioural and physiological topics: it is not our purpose to consider the early embryology of the bird - which is adequately covered by other texts - but we have included morphogenetic information where appropriate. The form of the book was dictated by a belief that interest in this aspect of development is not confined to embryologists, biochemists and physiolo­ gists. Therefore after describing the conditions in which the egg normally develops we have considered first the whole embryo: what it is like at different stages, what it does, how it gets from one position to another within the shell and how, later, it comes to interact with the wider environ­ ment of the nest. Only after this have we considered the development of the nervous and sensory mechanisms on which this transformation depends and on the problem of the level of behavioural maturity with which the chick emerges from the egg. With the main lines of development described we have, in the second part of the book, turned to a detailed consideration of the physiology of development: ranging from what may be conveniently described as the 'life-support' systems - gaseous exchange, provision of energy, etc. - to the of hormones in avian development.

Abstract: Notwithstanding its title, the reader will not find in this book a systematic account of this huge subject. Certain classical aspects have been passed by, and the true title ought to be "Various questions of elementary combina­ torial analysis". For instance, we only touch upon the subject of graphs and configurations, but there exists a very extensive and good literature on this subject. For this we refer the reader to the bibliography at the end of the volume. The true beginnings of combinatorial analysis (also called combina­ tory analysis) coincide with the beginnings of probability theory in the 17th century. For about two centuries it vanished as an autonomous sub­ ject. But the advance of statistics, with an ever-increasing demand for configurations as well as the advent and development of computers, have, beyond doubt, contributed to reinstating this subject after such a long period of negligence. For a long time the aim of combinatorial analysis was to count the different ways of arranging objects under given circumstances. Hence, many of the traditional problems of analysis or geometry which are con­ cerned at a certain moment with finite structures, have a combinatorial character. Today, combinatorial analysis is also relevant to problems of existence, estimation and structuration, like all other parts of mathema­ tics, but exclusively forjinite sets.

Abstract: Vacuum apparatus is widely used in research and industrial establishments for providing and monitoring the working environments required for the operation of many kinds of scientific instruments and process plant. The vacuum conditions needed range from the relatively coarse vacuum requirements in applications covering diverse fields such as food packaging, dentistry (investment casting), vacuum forming, vacuum metallur­ gical processes, vacuum impregnation, molecular distillation, vacuum drying and freeze drying etc. to the other extreme involving the highest possible vacuum as in particle accelerators, space technology -both in simulation and outer space, and research studies of atomically clean surfaces and pure condensed metal films. Vacua commence with the rough vacuum region, i.e. from atmosphere to 100 Pa * passing 6 through medium vacuum of 100 Pa to 0·1 Pa and high vacuum of 0·1 Pa to 1 J.lPa (10- Pa) until ultra high vacuum is reached below 1 J.lPa to the limit of measurable pressure about 12 I pPa (10- Pa).

Abstract: Books on engineering design, like designs them­ selves, are highly individual. In this one, the author emphasizes the importance of a visual approach to machine design and makes his point by including a large number of illustrations. He also stresses the need for clear objectives in all design work. Professor Leyer is an experienced designer and an inspiring teacher, and his book is based on his own lecture course in the subject. Throughout, he shows be the goal to which mathematics, mech­ design to anics and engineering drawing are the means. His book complements the usual range of engineering texts and can be read to advantage by students at any stage of their studies. In addition, he gives clear descriptive accounts of some important topics (such as stress concentration and the torsion of non­ circular sections) which are often omitted from textbooks because of their mathematical complexity. In controversial matters-the merits of the patent system, for example-Professor Leyer leaves us in no doubt as to his own views. In editing this translation I have used SI units for physical quantities and I urge readers to make their own calculations in this system whenevet they have the choice. It will be some years, however, before the familiar inch, foot and pound disappear alto­ gether and I have added the corresponding values in these units.

Abstract: While there are many books available on methods of organic and biochemical analysis, the majority are either primarily concerned with the application of a particular technique (e.g. paper chromatography) or have been written for an audience of chemists or for biochemists work­ ing mainly with animaltissues. Thus, no simple guide to modern metho ds of plant analysis exists and the purpose of the present volume is to fill this gap. It is primarily intended for students in the plant sciences, who have a botanical or a general biological background. It should also be of value to students in biochemistry, pharmacognosy, food science and 'natural products' organic chemistry. Most books on chromatography, while admirably covering the needs of research workers, tend to overwhelm the student with long lists of solvent systems and spray reagents that can be applied to each class of organic constituent. The intention here is to simplify the situation by listing only a few specially recommended techniques that have wide currency in phytochemical laboratories. Sufficient details are provided to allow the student to use the techniques for themselves and most sections contain some introductory practical experiments which can be used in classwork.

Abstract: One day in the summer of 1921 a postal delivery brought me a little packet of reprints from the periodical "Djawa" : articles about Indonesian music by Dr. JAAP KUNST, which until that moment had not come to my notice. A cursory glance was enough to convince me that the author was a very gifted man, who had made a sound and absolutely scientific study of the subject, and thereby made a valuable contribution, by means of careful observation and actual tone-measurements, to the facts known from the older studies by GRONEMAN, LAND and ELLIS. These measure­ ments were particularly satisfying to me personally, since they constituted an astonishing confirmation of a hypothesis concerning the genesis of tone­ systems (through the "cycle of blown fifths"), which I had propounded two years previously, without, however, having published it. At the same time it was proved, through the perfect conformity existing between the measured and the theoretical absolute pitches (vibration frequencies), that Indonesian gamelan tuning, too, belongs to the radius of ancient Chinese culture - much the same as is the case with Pan-pipes and xylo­ phones all over· the world. The first contact between Dr. KUNST and myself led to a regular cor­ respondence, which especially contributed to a further development of the above-mentioned theory of tone-systems.

Abstract: The history of printing, books, and libraries, is confined only to a limited extent within the boundaries of individual countries. There are, indeed, few historical developments which have played a more universal role, in reaction against all kinds of particularism, than type design, printing, book production, publishing, illustration, binding, librarianship, journal­ ism, and related subjects. Their history should be assessed and studied primarily in an international, not in a local, context. The bibliographical resources, however, which the historian of these sub­ jects has at his disposal correspond hardly at all to the essentially inter­ national character of the object of his studies. Since the appearance of the retrospective bibliography of BIG MORE and WYMAN, covering the subject comprehensively up to r88o, the only current bibliography has been the lnternationale Bibliographie des Buck-und Bi­ bliothekswesens. Covering a representative part of newly published liter­ ature, it appeared from rgz8, but did not survive the Second World War. More recently, several useful, but limited, bibliographies have appeared.

Abstract: This little book is written in the first place for students in technical colleges taking the National Certificate Courses in Applied Physics; it is hoped it will appeal also to students of physics, and pernaps chemistry, in the sixth forms of grammar schools and in the universltIes. For wherever experimental work in physics, or in science generally, is undertakcn the degree of accuracy of the measurements, and of the res,!lts of the experiments, must be of the first importance. Every teacher of experimental physics knows how "results" given to three or four decimal plaees are often in error in the first place; students suffer from "delusions of accuracy. " At a higher level too, more experieneed workers sometimes claim a degree of accuracy which cannot be justified. Perhaps a considera­ tion of the topics discussed in this monograph will stimulate in students an attitude to experimental results at onee more modest and more profound. The mathematical treatment throughout has been kept as simple as possible. It has seemed advisable, however, to explain the statistical concepts at the basis of the main considerations, and it is hoped that Chapter 2 contains as elementary an account of the leading statistical ideas involved as is possible in such small compass. It is a necessary link between the simple introduction to the nature and estimation of errors given in Chapter 1, and the theory of errors discussed in Chapter 3.

Abstract: This book brings together information which is used by engineers, and needed especially by students of engineering, but difficult to find in a collected form. In this respect engineering, perhaps because it is more often divided into separate branches, has so far been less well served than the other physical sciences; we hope to have in part redressed the balance. The contents are designed chiefly for engineering students of all kinds in universities and colleges, but they should also prove useful to practising engineers as a general reference. There was some difficulty in choosing numerical values for parts of the section Properties of Matter. Information was culled from a range of sources which sometimes show an alarming lack of consistency. Given a choice, we have used values which are either average or more likely to be reliable. The degree of tolerance required varies very widely between, for example, the precision to which thermodynamic proper­ ties of steam are known and the uncertainty in those mechanical properties of solids which depend strongly on quality and preparation.

Abstract: From prehistoric times man has had a pecial s relationship with seed plants - as a source of food, materials for tools, buildings, clothing and pharmaceuticals, and for ornamenting his surroundings for his own delight (probably in that chronological order which, incidentally, also gives some indication ofthe priorities oflife). Today man's most important staple foods are derived directly from seeds as they have been since neolithic times. (It is a sobering thought, as Harlan* has pointed out, that nothing significant has been added to his diet since then. ) From those times he must have learned to collect, conserve and cultivate seeds; and the accumulated experience has been handed down. This book then is part of an ancient tradition, for here we are still primarily concerned with these skills. Seeds are plant propagules comprised of embryos in which growth has been suspended, usually supplied with their own food reserves and protected by special covering layers. Typically they are relatively dry structures compared with other plant tissues and, in this condi­ tion) they are resistant to the ravages of time and their environment. But resistant is a relative tenn and seeds do deteriorate: the type, the extent and the rapidity of the deterioration, and the factors which control it are important to agronomists, horticulturalists, plant breeders, seedsmen, seed analysts, and those concerned with the conservation of genetic resources.

Abstract: INSECTS PROVIDE an ideal medium in which to study all the problems of physiology. But if this medium is to be used to the best advantage, the principles and peculiarities of the insect's organization must be first appreciated. It is the purpose of this book to set forth these principles so far as they are understood at the present day. There exist already many excellent text-books of general ento­ mology; notably those of Imms, Weber, and Snodgrass, to mention only the more recent. But these authors have necessarily been preoccupied chiefly with describing the diversity of form among insects; discussions on function being correspondingly condensed. In the present work the emphasis is reversed. Struc­ ture is described only to an extent sufficient to make the physiological argument intelligible. Every anatomical peculiarity, every ecological specialization, has indeed its physiological counterpart. In that sense, anatomy, physiology and ecology are not separable. But regarded from the standpoint from which the present work is written, the endless modifications that are met with among insects are but illustrations of the general principles of their physiology, which it is the aim of this book to set forth. Completeness in such a work is not possible, or desirable; but an endeavour has been made to illustrate each physiological characteristic by a few concrete examples, and to include sufficient references to guide the student to the more important sources. The physiology of insects is to some the handmaid of Economic Entomology.

Abstract: HIS BOOK IS INTENDED TO PROVIDE A COURSE IN PRACTICAL Geometry for engineering students who have already received some instruction in elementary plane geometry, graph plotting, and the use T of vectors. It also covers the requirements of Secondary School pupils taking Practical Geometry at the Advanced Level. The grouping adopted, in which Plane Geometry is dealt with in Part I, and Solid or Descriptive Geometry in Part II, is artificial, and it is the intention that the two parts should be read concurrently. The logical treatment of the subject presents many difficulties and the sequence of the later chapters in both parts is necessarily a compromise; as an illustration, certain of the more easy inter­ sections and developments might with advantage be taken at an earlier stage than that indicated. In Part I considerable space has been devoted to Engineering Graphics, particularly to the applications of graphical integration. The use of graphical methods of computation is fully justified in most engineering problems of a practical nature-especially where analytical methods would prove laborious -the results obtained being as accurate as the data warrant.
