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: In the first BACOMET volume different perspectives on issues concerning teacher education in mathematics were presented (B. Christiansen, A. G. Howson and M. Otte, Perspectives on Mathematics Education, Reidel, Dordrecht, 1986). Underlying all of them was the fundamental problem area of the relationships between mathematical knowledge and the teaching and learning processes. The subsequent project BACOMET 2, whose outcomes are presented in this book, continued this work, especially by focusing on the genesis of mathematical knowledge in the classroom. The book developed over the period 1985-9 through several meetings, much discussion and considerable writing and redrafting. Our major concern was to try to analyse what we considered to be the most significant aspects of the relationships in order to enable mathematics educators to be better able to handle the kinds of complex issues facing all mathematics educators as we approach the end of the twentieth century. With access to mathematics education widening all the time, with a multi­ tude of new materials and resources being available each year, with complex cultural and social interactions creating a fluctuating context of education, with all manner of technology becoming more and more significant, and with both informal education (through media of different kinds) and non­ formal education (courses of training etc. ) growing apace, the nature of formal mathematical education is increasingly needing analysis.

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: 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. Researchers also can find value in the foundations laid down by the text, es­ pecially in regard to the needs and concerns of the processing industry. Also, consultants and marketing personnel will be greatly helped by understanding the concepts of this volume. Persons in related industries also will find many applications that can be easily adapted to their needs.

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: Over the last 20 years there have been a large number of technical advances and changes in the field of educational and psychological testing. According to Anne Anastasi, The decade of the 1980's has been a period of unusual advances in ,psychological testing. Technological progress, theoretical sophistication, and increasing pro­ fessional responsibility are all evident in the fast-moving events in this field (A. Anastasi, Psychological Testing, Sixth Edition. New York: Macmillan, 1988). On the psychometric front, advances in topics such as item response theory, criterion-referenced measurement, generalizability theory,· analy­ sis of covariance structures, and validity generalization are reshaping the ways that ability and achievement tests are constructed and evaluated, and that test scores are interpreted. But \Jsychometric advances, as substantial and important as they have been, are only a fraction of the major changes in the field of testing. Today, for example, the computer is radically chang­ ing the ways in which tests are constructed, administered, and scored. Computers are being used to administer tests "adaptively." That is, the sequence of questions an examinee is administered depends upon his or her performance on earlier administered items in the test. Tests are "adapted" to the ability levels of the examinees who are being assessed. One result is shorter tests with little or no loss in measurement precision. Computers are also being used to store or bank test items. Later, items of interest can be selected, and the computer is used to print copies of the test.

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: Public concern about the safety and healthfulness of the food supply grew markedly during the 1980s. 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 topic to which this book is devoted is reductionism, and not reduction. The difference in the adoption of these two denominations is not, contrary to what might appear at first sight, just a matter of preference between a more abstract (reductionism) or a more concrete (reduction) terminology for indicating the same sUbject matter. In fact, the difference is that between a philosophical doctrine (or, perhaps, simply a philosophical tenet or claim) and a scientific procedure. Of course, this does not mean that these two fields are separated; they are only distinct, and this already means that they are also likely to be interrelated. However it is useful to consider them separately, if at least to better understand how and why they are interconnected. Just to give a first example of difference, we can remark that a philosophical doctrine is something which makes a claim and, as such, invites controversy and should, in a way, be challenged. A scientific procedure, on the other hand, is something which concretely exists, and as such must be first of all described, interpreted, understood, defined precisely and analyzed critically; this work may well lead to uncovering limitations of this procedure, or of certain ways of conceiving or defining it, but it does not lead to really challenging it.

Abstract: Human existence is marked by pain, limitation, disability, disease, suffering, and death. These facts of life and of death give ample grounds for characterizing much of the human condition as unfortunate. A core philosophical question is whether the circumstances are in addition unfair or unjust in the sense of justifying claims on the resources, time, and abilities of others. The temptation to use the languages of rights and of justice is und- standable. Faced with pain, disability, and death, it seems natural to complain that "someone should do something", "this is unfair", or "it just isn't fight that people should suffer this way". Yet it is one thing to complain about the unfairness of another's actions, and another thing to complain about the unfairness of biological or physical processes. If no one is to blame for one's illness, disability, or death, in what sense are one's unfortunate circumstances unfair or unjust? How can claims against others for aid and support arise if no one has caused the unfortunate state of affairs? To justify the languages of fights to health care or justice in health care requires showing why particular unfortunate circumstances are also unfair, in the sense of demanding the labors of others. It requires understanding as well the limits of property claims. After all, claims regarding justice in health care or about fights to health care limit the property fights of those whose resources will be used to provide care.

Abstract: This collection is the final volume of a four book survey of the state of phenomenology fifty years after the death of Edmund Husserl. Its publication represents a landmark in the comprehensive treatment of contemporary phenomenology in all its vastness and richness. The diversity of the issues raised here is dazzling, but the main themes of Husserl's thought are all either explicitly treated, or else they underlie the ingenious approaches found here. Time, historicity, intentionality, eidos, meaning, possibility/reality, and teleology are the main concerns of this collection devoted to studies in aesthetics, metaphysics and literary interpretation, written by such authors as, among others, R. Cobb-Stevens, C. Moreno Marquez, J. Swiecimski, Sitansu Ray and M. Kronegger. These original studies of phenomenological aesthetics and literary theory by scholars from all parts of the world were gathered by the World Institute for Advanced Phenomenological Research and Learn­ ing during the year 1988/89 during its assessment of the phenomeno­ logical movement, fifty years after Husserl's death.

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: 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: This book grew out of my confusion. If logic is objective how can there be so many logics? Is there one right logic, or many right ones? Is there some underlying unity that connects them? What is the significance of the mathematical theorems about logic which I've learned if they have no connection to our everyday reasoning? The answers I propose revolve around the perception that what one pays attention to in reasoning determines which logic is appropriate. The act of abstracting from our reasoning in our usual language is the stepping stone from reasoned argument to logic. We cannot take this step alone, for we reason together: logic is reasoning which has some objective value. For you to understand my answers, or perhaps better, conjectures, I have retraced my steps: from the concrete to the abstract, from examples, to general theory, to further confirming examples, to reflections on the significance of the work.

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.

Falk and William Hughes for helping us with the translation. We also owe thanks to Professor Herbert Spiegelberg, Dr. Walter Biemel and the Husser! Archives at Louvain for checking it and we are especially indebted to Professor Dorion Cairns, many of whose suggestions we incorporated in the final draft. WILLIAM P. ALSTON GEORGE NAKHNIKIAN January 1964 CONTENTS V Preface Introduction IX The train of thoughts in the lectures I Lecture I 13 Lecture II 22 Lecture III 33 Lecture IV 43 Lecture V 52 INTRODUCTION From April 26 to May 2, 1907, Husserl delivered five lectures in Gottingen. They introduce the main ideas of his later pheno­ menology, the one that goes beyond the phenomenology of the Logische Untersuchungen. These lectures and Husserl's summary of them entitled "The Train of Thoughts in the Lectures" were edited by Dr. Walter Biemel and first published in 1950 under the 1 title Die Idee der Phiinomenologie. Husserl wrote the summary on the night of the last lecture, not for formal delivery but for his own use. This accounts for the fact that the summary contains incomplete sentences. There are some discrepancies between Lecture V and the corresponding passages in the summary. We may suppose that the passages in the summary are a closer approximation to what Husserl wanted to say.

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: The world is increasingly becoming . one. It is, at the same time, one endangered ecosystem and one thriving market place with material and spiritual goods on competitive display. And the good and evil things of life cannot easily be sorted out. The world is becoming one also in the sense that it is better understood today than it was in earlier times, that the material good and the spiritual good, though seemingly belonging to different realms of fact defined by their respective modes of existence, together constitute effectively one and the same reality: the modem world of science, technology, computerized administration and power, that calls upon humankind to struggle for a 'just, participatory and sustainable society' * , and to strive for a society of the future that will be the world over both long-lived and worth living. The Second European Conference on Science and Religion, held on 10-13th. March, 1988, on the campus of the Universiteit Twente, Enschede, The Netherlands, was meant to be a modest market place, a forum, where standpoints and opinions could be presented and criticized. It was meant to offer an opportunity to meet and to make acquaintances in the expectation that the exchange of thoughts would lead to new conceptual horizons that would challenge what so far had been considered as hard fact or what until now had been looked upon as a distinctive feature of a well-established view either of the kingdom of the sciences or of the realm of religion.

Abstract: lt is a commonplace that law and morality intersect and interpenetrate in all the areas of legal decision-making; that in order to make sense of constitutional, statutory or common-law questions, judges and other legal decision-makers must first resolve certain philosophical issues which include moral judgments of right and wrang_ This is particularly evident with regard to constitutional interpretation, especially when constitutions give a mandate for the protection of the substantive norms and values entrenched as constitutional rights. In these Situations, as a leading contemporary legal philosopher observed, the "Constitution fuses legal and moral issues, by making the validity of a law depend on an answer to complex moral 1 problems". But the need for substantive value elucidation is not confined, of course, only to constitutional interpretation under Bills of Rights. This, however, immediately raises a dilemma stemming from the moral diversity and pluralism of modern liberal societies. How can law remain sensitive to this pluralism and yet provide clear answers to the problems which call for a legal resolution? Sharply conflicting values in modern societies clash in the debates over the death penalty, abortion, homosexuality, separation of state and religion, the scope of the freedom of the press, or affirmative action. lt would often be difficult to discern a broader consensus within which these clashes of values operate, unless this consensus were described in such vague terms as to render it practically meaningless.

Abstract: I: Characterization of Interface -- II: Surface of Reinforcements -- III: Controlled Interphase -- IV: Interfacial Theories -- V: Influence of Interface on Mechanical and Physical Properties -- Author Index.

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: 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: 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: 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: 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: 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 essays in this collection are written by students, colleagues, and friends of Nuel Belnap to honor him on his sixtieth birthday. Our original plan was to include pieces from fonner students only, but we have deviated from this ever so slightly for a variety of personal and practical reasons. Belnap's research accomplishments are numerous and well known: He has founded (together with Alan Ross Anderson) a whole branch of logic known as "relevance logic." He has made contributions of fundamental importance to the logic of questions. His work in modal logic, fonnal pragmatics, and the theory of truth has been highly influential. And the list goes on. Belnap's accomplishments as a teacher are also distinguished and well known but, by virtue of the essential privacy of the teaching relationship, not so well understood.

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: 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: 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: 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: 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: 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.
