    Abstract: Beverage production is among the oldest, though quantitatively most significant, applications of biotechnology methods, based on the use of microorganisms and enzymes. Manufacturing processes employed in beverage production, origi­ nally typically empirical, have become a sector of growing economic importance in the food industry. Pasteur's work represented the starting point for technological evolution in this field, and over the last hundred years progress in scientifically based research has been intense. This scientific and technological evolution is the direct result of the encounter between various disciplines (chemistry, biology, engineering, etc.). Beverage production now exploits all the various features of first and second-generation biotechnology: screening and selective im­ provement of microorganisms; their mutations; their use in genetic engineering methods; fermentation control; control of enzymatic processes, including industrial plants; use of soluble enzymes and immobilized enzyme reactors; development of waste treatment proc­ esses and so on. Research developments involving the use of biotechnology for the purpose of improving yields, solving quality-related problems and stimulating innovation are of particular and growing interest as far as production is concerned. Indeed, quality is the final result of the regulation of microbiological and enzymatic processes, and innovation is a consequence of improved knowledge of useful fermentations and the availability of new ingredients. The Council of Europe's sponsorship of the work which led to the contributions to this volume is clear evidence of the growing need for adequate information about scientific and technological progress.

    Abstract: THE SENSE OF SMELL The nose is normally mistakenly assumed to be the organ of smell reception. It is not. The primary function of the nose is to regulate the temperature and humidity of inspired air, thereby protecting the delicate linings of the lungs. This is achieved by the breathed air passing through narrow passageways formed by three nasal turbinates in each nostril. The turbinates are covered by spongy vascular cells which can expand or contract to open or close the nasal pathways. The olfactory receptors, innervated by the 1st cranial nerve, are located at the top of the nose. There are about 50 million smell receptors in the human olfactory epithelia, the total size of which, in humans, is about that of a small postage stamp, with half being at the top of the left and half at the top of the right nostril. The receptive surfaces of olfactory cells are ciliated and extend into a covering layer of mucus. There is a constant turnover of olfactory cells. Their average active life has been estimated to be about 28 days.

    Abstract: In the last few years there has been a tremendous increase in the number of Pascal courses taught at various levels in schools and universities. Also with the advances made in electronics it is possible today for the majority of people to own or have access to a microcomputer which invariably runs BASIC and Pascal. A number of Pascal implementations exist and in the last two years a new Pascal specification has emerged. This specification has now been accepted as the British Standard BS6192 (1982). This standard also forms the technical content of the proposed International Standard IS07185. In addition to a separate knowledge of electronic engineering and programming a marriage of engineering and computer science is required. The present method of teaching Pascal in the first year of electronic engineering courses is wasteful. Little, if any, benefit is derived from a course that only teaches Pascal and its use with abstract examples. What is required is continued practice in the use of Pascal to solve meaningful problems in the student's chosen discipline. The purpose of this book is to make the use of standard Pascal (BS6192) as natural a tool in solving engineering problems as possible. In order to achieve this aim, only problems in or related to electrical and elec­ tronic engineering are considered in this book. The many worked examples are of various degrees of difficulty ranging from a simple example to bias a transistor to programs that analyse passive RLC networks or synthesise active circuits.

    Abstract: The Sources and Nature of the Statistics of the United Kingdom, produced under the auspices of the Royal S~atistical Society and edited by Maurice Kendall, filled a notable gap on the library shelves when it made its appearance in the early post-war years. Through a series of critical reviews by many of the foremost national experts, it constituted a valuable contemporary guide to statisticians working in many fields as well as a bench-mark to which historians of the development of Statistics in this country are likely to return again and again. The Social Science Research Council* and the Society were both delighted when Professor Maunder came forward with the proposal that a revised version should be produced, indicating as well his willingness to take on the onerous task of editor. The two bodies were more than happy to act as co-sponsors of the project and to help in its planning through a joint steering committee. The result, we are confident, will be judged a worthy successor to the previous volumes by the very much larger 'statistics public' that has come into being in the intervening years.

    Abstract: While preparing the first edition of this textbook I attended an extension short course on writing agricultural publications. The message I remember was "select your audience and write to it. " There has never been any doubt about the audience for which this textbook was written, the introductory course in crop breeding. In addition, it has become a widely used reference for the graduate plant-breeding student and the practicing plant breeder. In its prepa­ ration, particular attention has been given to advances in plant-breeding theo­ ry and their utility in plant-breeding practice. The blend of the theoretical with the practical has set this book apart from other plant-breeding textbooks. The basic structure and the objectives of the earlier editions remain un­ changed. These objectives are (1) to review essential features of plant re­ production, Mendelian genetic principles, and related genetic developments applicable in plant-breeding practice; (2) to describe and evaluate established and new plant-breeding procedures and techniques, and (3) to discuss plant­ breeding objectives with emphasis on the importance of proper choice of objec­ tive for achieving success in variety development. Because plant-breeding activities are normally organized around specific crops, there are chapters describing breeding procedures and objectives for the major crop plants; the crops were chosen for their economic importance or diversity in breeding sys­ tems. These chapters provide a broad overview of the kinds of problems with which the breeder must cope.

    Abstract: The role of the European Community in developing environmental legislation has focused the minds of pollution control agencies and industrialists on the need for, and the evidence to support, water quality standards. This is particularly so for the Dangerous Substances Directive which has led to European standards for cadmium, mercury and lindane. Additionally the United Kingdom has published standards for six other non-ferrous metals. In this book I have sought to review the aquatic toxicity information for these and other metals, not just by the collation of the results of all the published toxicity tests, but by the critical consideration of the test techniques. A surprising proportion of the reported toxicity studies for aquatic organisms are based on unsatisfactory chemical or biological methods. That such weaknesses persist at a time of limited resources for environmental research is disappointing, especially when sound metho­ dologies are extensively documented and widely published. Evaluation of the critically reviewed and vetted data indicates that many of the previously accepted generalisations about the toxicity of metals to aquatic life are invalid: for instance the assumption that salmonid species of fish are more susceptible to these metals than coarse fish, or that increased water hardness decreases toxicity. Too few studies have actually sought to test such hypotheses.

    Abstract: a priori, and what is more, to a rejection based ultimately on a posteriori findings; in other words, the "pure" science of nature in Kant's sense of the term had proved to be, not only not pure, but even false. As for logic and mathematics, the decisive works of Frege, Russell, and White­ head suggested two conclusions: first, that it was possible to construct mathematics on the basis of logic (logicism), and secondly, that logical propositions had an irrevocably analytic status. But within the frame­ work of logicism, the status of logical propositions is passed on to mathematical ones, and mathematical propositions are therefore also conceived of as analytic. All this creates a situation where the existential presupposition contained in the Kantian question about the possibility of judgements that are both synthetic and a priori must, it seems, be rejected as false. But to drop this presupposition is, at the same time, to strike at the very core of Kant's programme of putting the natural sciences on a philosophical foundation. The failure of the modern attempt to do so suggests at the same time a reversal of the relationship between philosophy and the individual sciences: it is not the task of philosophy to meddle with the foundations of the individual sciences; being the less successful discipline, its task is rather to seek guidance from the principles of rationality operative in the individual sciences.

    Abstract: How quickly the technological 'flavour of the month' changes. At the beginning of the 1980's many saw 'robotics' as being something of a pana­ cea for those problems in the manufacturing industries which had been exacerbated by the world recession. Those working at the time in the field of robotics stressed that robots themselves were only part of the solution. Yet in many quarters the 'hype' for the new technology apparently knew few bounds, resulting, inexorably, in many industries painfully discover­ ing for themselves a new realism, closely followed by disillusionment. In its wider sense the term 'robotics' covers an extremely broad spec­ trum of technologies ranging from extremely flexible, highly sensory and integrated systems capable of handling a very diverse product range, through to comparatively inflexible, high volume systems which can merely handle slightly different variations of the same basic product. As a result of the one 'buzzword' referring to such a variety of actual system­ types, the disillusionment which started to become apparent during the early 1980's acted as something of a double edged sword. A given com­ pany might consider a particular robotics-based technological solution to its production problems, find that it was unsuitable, and so renounce all robotics approaches as inappropriate. Yet just because one position on that spectrum of technological solutions was unsuitable for the company should not have led them to assume that there was no other robotics solu­ tion that was appropriate.

    Abstract: A preface should justify the existence of the book it precedes and this is invariably done in scientific texts by reference to the explosive growth of the field since the last such volume appeared. In molecular biology, most fields can be justifiably described as growing explosively, as should be the case for a young and vigorous science, but the study of membrane proteins stands out as one which has taken giant strides in the last few years. Ignorance of the structure and function of membrane proteins at the molecular level was certainly not due to lack of interest but rather was a result of lack of appropriate techniques. It has above all been the development of new experimental methods which has wrenched membrane biochemistry out of what Anthony Martonosi fetchingly called its 'romantic phase' (Le. lots of ideas and few facts), into an era when the determination of membrane protein structure and mechanism is a reasonable goal. Membrane proteins are generally classified as peripheral or integral. Peripheral proteins are relatively easily dissociated from membranes by mild treatments whence their study is essentially no different to that of soluble proteins. This book therefore concentrates on integral proteins which are strongly bound to the membrane by hydrophobic interactions with lipids. A crucial step in their study is of necessity the d~velopment of methods of solubilization and purification under non-denaturing conditions.

    Abstract: H, as it is often said, mathematics is the queen of science then algebra is surely the jewel in her crown. In the course of its vast development over the last half-century, algebra has emerged as the subject in which one can observe pure mathe­ matical reasoning at its best. Its elegance is matched only by the ever-increasing number of its applications to an extraordinarily wide range of topics in areas other than 'pure' mathematics. Here our objective is to present, in the form of a series of five concise volumes, the fundamentals of the subject. Broadly speaking, we have covered in all the now traditional syllabus that is found in first and second year university courses, as well as some third year material. Further study would be at the level of 'honours options'. The reasoning that lies behind this modular presentation is simple, namely to allow the student (be he a mathematician or not) to read the subject in a way that is more appropriate to the length, content, and extent, of the various courses he has to take. Although we have taken great pains to include a wide selec­ tion of illustrative examples, we have not included any exer­ cises. For a suitable companion collection of worked examples, we would refer the reader to our series Algebra through practice (Cambridge University Press), the first five books of which are appropriate to the material covered here.

    Abstract: The preface of a book often provides a convenient place in which the author can tender his apologies for any inadequacies and affords him the facility to excuse himself by reminding the reader that his art is long but life, or at least the portion of it in which he has the opportunity for writing books, is short. I, too, am deeply conscious that I have undertaken a task which I could not hope to complete to my own satisfaction but I offer, in self­ defence, the observation that, inadequate though it is, there is no other book extant, so far as I am aware, which provides the information contained herein within the covers of a single volume. Often during the last decade, in discharging my responsibilities for the environmental aspects of the water authority's operations and works, I should have been deeply grateful to have had access to a compendium such as this. The lack of a convenient source of data made me aware of the need which I have attempted to fill and in doing so I have drawn on my experiences of the kinds of problem which are presented to biologists in the water industry. The maxim 'half a loaf is better than none' seems particularly apt in this context.

    Abstract: Semiconductors have been used widely in signal-level or "brain" applications. Since their invention in 1948, transistors have revolutionized the electronics industry in computers, information processing, and communications. Now, however, semiconductors are being used more and more where consid­ erable "brawn" is required. Devices such as high-power bipolar junction tran­ sistors and power field-effect transistors, as well as SCRs, TRlACs, GTOs, and other semiconductor switching devices that use a p-n-p-n regenerative effect to achieve bistable action, are expanding the power-handling horizons of semicon­ ductors and finding increasing application in a wide range of products including regulated power supplies, lamp dimmers, motor drives, pulse modulators, and heat controls. HVDC and electric-vehicle propulsion are two additional areas of application which may have a very significant long range impact on the tech­ nology. The impact of solid-state devices capable of handling appreciable power levels has yet to be fully realized. Since it first became available in late 1957, the SCR or silicon-controlled rec­ tifier (also called the reverse blocking triode thyristor) has become the most popular member of the thyristor family. At present, SCRs are available from a large number of manufacturers in this country and abroad. SCR ratings range from less than one ampere to over three thousand amperes with voltage ratings in excess of three thousand volts.

    Abstract: I have tried in this book to introduce the basic concepts of electromagnetic field theory at a level suitable for students entering degree or higher diploma courses in electronics or subjects allied to it. Examples and applications have been drawn from areas such as instrumentation rather than machinery, as this was felt to be more apt for the majority of such readers. Some students may have been following courses with a strong bias towards prac­ tical electronics and perhaps not advanced their understanding of the physics of electric and magnetic fields greatly since '0' level or its equivalent. The book there­ fore does not assume that 'A' level physics has been studied. Students of BTEC courses or 'A' level subjects such as technology might also find the material useful. At the other extreme, students who have achieved well on an 'A' level course will, it is hoped, find stimulating material in the applications discussed and in the marginal notes, which suggest further reading or comment on the deeper implica­ tions of the work.

    Abstract: There is a rapidly expanding literature on the economics of the so­ called 'new technologies' - especially on those using microelectronic systems. Dr. Jacobsson's book deals with microelectronics-based innovation in machine tools: with the production and use of computer numerically controlled machine tools in the world economy and especially in the Third World. Jacobsson is mainly interested in the implications which CNC machine tools may be expected to have for users and producers in the Newly Industrialising Countries. He approaches this as a problem in applied economics and the book will have a primary interest for those economists whose concern is with the problems of industrialisation in developing countries. It will be parti­ cularly valuable to those who are preoccupied with the role of local capital goods manufacture and with the technological preconditions for this kind of production. Jacobsson is able to give detailed and specific arguments on these matters as far as CNC machine tools are concerned. In my view, the book has a considerably wider interest and relevance than its specification may at first sight suggest. Jacobsson's achieve­ ment is not just that he has provided valuable and convincing quantita­ tive arguments about policy in setting up production of CNC machine tools. In addition, he has set a new and much needed methodological standard for analysis of the impacts of 'new technologies' on the international economy.

    Abstract: This book is about selectively toxic agents. That is to say, it is about those substances that affect certain cells without harming others, even when they are close neighbours. Toxicity need not be fatal. It can be made easily reversible, as is the case with general anaesthetics. Selective toxicity covers an immense field: most of the drugs used for treating illness in man and his economic animals, as well as all of the fungicides, insecticides, and weed killers that are used in agriculture. Essentially, this book is a discussion of the physical and chemical means which contribute to selectivity, and this is the basis of molecular pharmacology. _Selective Toxicity began as a course of lectures that Professor F. G. Young encouraged me to give in University College London, in 1948 and again in 1949. The first edition appeared in 1951, as a very small book because little was then known about the factors that provide selectivity. Since those early days, the subject has undergone tremendous development. At first, industry was un­ receptive to the word 'toxicity', however qualified! Yet the market was being supplied with biologically powerful substances of which several had the potential to cause harm. This aspect was brought to light by two events of the early 1960s. The first of these was the discovery that a sedative, thalidomide, administered to expectant mothers, after what was then considered to be adequate testing, had caused permanent deformities in about 10000 children.

    Abstract: Remote sensing using aircraft and satellites has helped to open up to intensified scientific scrutiny the cold and remote regions in which snow and ice are prevalent. In this book, the utility of remote sensing for identifying, mapping and analyzing surface and subsurface properties of worldwide ice and snow features is described. Emphasis is placed on the use of remote sensing for developing an improved understanding of the physical properties of ice and snow and understanding the interrelationships of cryospheric processes with atmospheric, hydrospheric and oceanic processes. Current and potential applications of remotely sensed data are also stressed. At present, all-weather, day and night observations of the polar regions can be obtained from sensors operating in different portions of the electromagnetic spectrum. Because the approaches for analysis of remotely sensed data are not straightforward, Chapter 1 serves to introduce the reader to some of the optical, thermal and electrical properties of ice and snow as they pertain to remote sensing. In Chapter 2 we briefly describe many of the sensors and platforms that are referred to in the rest of the book. The remaining chapters deal with remote sensing of the seasonal snow cover, lake and river ice, permafrost, glacier ice and sea ice.

    Abstract: In recent years there has been a rapid increase in the understanding of communication between animals and this is perhaps especially true of bio-acoustics. In the last 35 years a completely new branch of bio­ acoustics, involving ultrasounds, has been made possible by technical developments that now allow these inaudible sounds to be detected and studied. This subject has a personal fascination for the authors, perhaps because of the novelty of 'listening in' to these previously unknown sig­ nals, perhaps because of the wide variety of ways in which different animals use them. Many studies of different aspects of animal ultrasound have now been published and a review of them all seems to be timely. Ultrasound is is biologically arbitrary; other animals defined in human terms and may produce similar signals at lower frequencies for similar purposes. This book attempts to be comprehensive but the limits of the subject are rather difficult to define. It should be read in conjunction with other books on audible bio-acoustics. Each chapter has been written and may be read as a separate entity, although there is considerable cross-referencing. Chapters 1 and 2 form a common introduction and may help in understanding the later sections. The Appendix is not essential but is included for those who may be interested in the quanti­ tative aspects of the echo-location phenomena described in Chapters 3 and 8.

The scope of the subject matter necessitated a narrow and slippery path be­ tween over-simplification and excessive detail, but the balance adopted is based upon the experience of many years of teaching at all levels, and of examining for the London G.C.E. Board. The maps, combining outcrop dis­ tribution with palaeogeography, presented some difficulty, especially for periods of continuously changing geography, such as the Cretaceous. It was necessary in these cases to make an arbitrary choice of one small part of the period, the geography of which could be illustrated. Candidates are advised not to spend time learning every detail of the outcrop patterns, but to con­ centrate upon the main areas of outcrop. I am indebted to Mrs. Jean Fyffe for the cartographic work.

    Abstract: During the last decade the techniques of non-linear optim­ ization have emerged as an important subject for study and research. The increasingly widespread application of optim­ ization has been stimulated by the availability of digital computers, and the necessity of using them in the investigation of large systems. This book is an introduction to non-linear methods of optimization and is suitable for undergraduate and post­ graduate courses in mathematics, the physical and social sciences, and engineering. The first half of the book covers the basic optimization techniques including linear search methods, steepest descent, least squares, and the Newton-Raphson method. These are described in detail, with worked numerical examples, since they form the basis from which advanced methods are derived. Since 1965 advanced methods of unconstrained and constrained optimization have been developed to utilise the computational power of the digital computer. The second half of the book describes fully important algorithms in current use such as variable metric methods for unconstrained problems and penalty function methods for constrained problems. Recent work, much of which has not yet been widely applied, is reviewed and compared with currently popular techniques under a few generic main headings. vi PREFACE Chapter I describes the optimization problem in mathemat­ ical form and defines the terminology used in the remainder of the book. Chapter 2 is concerned with single variable optimization. The main algorithms of both search and approximation methods are developed in detail since they are an essential part of many multi-variable methods.

    Abstract: This book is a new attempt to interrelate the chemistry of the non-metals. In the early chapters, simple compounds of the non-metals with the halogens, hydrogen, and oxygen are surveyed, permitting a large area of chemistry to be discussed without the burden of too many facts. The structural relationships in the elemental forms of the non-metals are then used as an introduction to the catenated compounds, including the boron hydrides. In the concluding chapter, selected heteronuclear chain, ring, and cage compounds are con­ sidered. In some chapters, we have thought it useful to outline important features of a topic in relation to chemical theory, before giving a more detailed ac count of the chemistry of individual elements. The book is certainly not comprehensive and the bias in the material selected probably reflects our interest in volatile, covalent non-metal compounds. Suggestions for furt her reading are presented in two ways. A selected bibliography lists general textbooks which relate to much of our subject matter. References in the text point to review articles and to a few original papers which we consider to be of special interest. Although there are few difficult concepts in the text, the treatment may be appreciated most by students with some previous exposure to a Group by Group approach to non-metal chemistry. We have assumed an elementary knowledge of chemical periodicity, bonding theory, thermodynamics, and spectroscopic methods of structure determination.

    Abstract: This publication, in two volumes, includes most of the scientific papers presented at the first meeting of the International Society for the Study of the Origin of Life (lSSOL), held on June 25-28, 1973 in Barcelona, Spain. The first volume contains the invited articles and the second volume the contributed papers, which also appear in the 1974 and 1975 issues, respectively, of the new journal Origins of Life, published by D. Reidel. A relatively large number of meetings on the subject of the origin of life have been held in different places since 1957. In terms of its organization, scope, and number and nationality of participants, the Conference celebrated last year in Barcelona closely followed the three international conferences held earlier in Moscow, U.S.S.R., 1957, Wakulla Springs, U.S.A., 1963, and Pont-a-Mousson, France, 1970. For this reason the first ISSOL meeting was also named the 4th International Conference on the Origin of Life.

    Abstract: The following pages are meant for those who wish to use thyristors. The details of the physics of semiconductor materials or the design of thyristors themselves are unnecessary here but a general description of the device may help to avoid pitfalls during electric circuit design. Thyristor is the internationally recognized name for a particular semi­ conductor device. The name is derived from the Greek, the first part meaning switch and the second part an association with the transistor family. It has a trade name, viz. SCR (silicon controlled rectifier) and it got this name principally because it is a silicon device and it is used as a rectifier which can be controlled. As a controlled switch it forms a group together with the electromagnetic relay, the thyratron and the mercury arc rectifier. The advantages and disadvantages of the thyristor become apparent in the process of describing the device and its range of application. However, the present general interest, development and use of the thyristor, indicates that for many cases its many advantages make it superior to other devices. Control of rotating electric machines is a major interest of the author so that in this book the applications of the thyristor are towards this end. Thyristors are used so much in connection with the control of machines that it is worthwhile to go into some details of both the electric drive to be controlled and the possible thyristor control units.

    Abstract: I have tried to provide an introduction, at an elementary level, to some of the important topics in real analysis, without avoiding reference to the central role which the completeness of the real numbers plays throughout. Many elementary textbooks are written on the assumption that an appeal to the complete­ ness axiom is beyond their scope; my aim here has been to give an account of the development from axiomatic beginnings, without gaps, while keeping the treatment reasonably simple. Little previous knowledge is assumed, though it is likely that any reader will have had some experience of calculus. I hope that the book will give the non-specialist, who may have considerable facility in techniques, an appreciation of the foundations and rigorous framework of the mathematics that he uses in its applications; while, for the intending mathe­ matician, it will be more of a beginner's book in preparation for more advanced study of analysis. I should finally like to record my thanks to Professor Ledermann for the suggestions and comments that he made after reading the first draft of the text.

    Abstract: This book is primarily intended for graduate chemists and chemical physicists. Indeed, it is based on a graduate course that I give in the Chemistry Depart­ ment of Southampton University. Nowadays undergraduate chemistry courses usually include an introduction to quantum mechanics with particular reference to molecular properties and there are a number of excellent textbooks aimed specifically at undergraduate chemists. In valence theory and molecular spectroscopy physical concepts are often encountered that are normally taken on trust. For example, electron spin and the anomalous magnetic moment of the electron are usually accepted as postulates, although they are well understood by physicists. In addition, the advent of new techniques has led to experimental situations that can only be accounted for adequately by relatively sophisticated physical theory. Relativis­ tic corrections to molecular orbital energies are needed to explain X-ray photo­ electron spectra, while the use oflasers can give rise to multiphoton transitions, which are not easy to understand using the classical theory of radiation. Of course, the relevant equations may be extracted from the literature, but, if the underlying physics is not understood, this is a practice that is at best dissatisfy­ ing and at worst dangerous. One instance where great care must be taken is in the use of spectroscopically determined parameters to test the accuracy of elec­ tronic wave functions.

    Abstract: This work sets out to provide an up-to-date account of the physical properties and structure of polymers in the glassy state. Properties measured above the glass transition temperature are therefore included only in so far as is necessary for the treatment of the glass transition process. This approach to the subject therefore excludes any detailed account of rubber elasticity or melt rheology or of the structure and conformation of the long chain molecule in solution, although knowledge derived from this field is assumed where required. Major emphasis is placed on structural and mechanical properties, although a number of other physical properties are included. Naturally the different authors contributing to the book write mainly from their own particular points of view and where there are several widely accepted theoretical approaches to a subject, these are sometimes provided in different chapters which will necessarily overlap to a significant extent. For example, the main theoretical presentation on the subject of glass transition is given in Chapter 1. This is supplemented by accounts of the free volume theory in Chapter 3 and in the Introduction, and a short account of the work of Gibbs and DiMarzio, also in Chapter 3. Similarly, there is material on solvent cracking in Chapters 7 and 9, though the two workers approach the subject from opposite directions. Every effort has therefore been made to encourage cross-referencing between different chapters.

    Abstract: Linear programming is a relatively modern branch of Mathe­ matics, which is a result of the more scientific approach to management and planning of the post-war era. The purpose of this book is to present a mathematical theory of the subject, whilst emphasising the applications and the techniques of solution. An introduction to the theory of games is given in chapter five and the relationship between matrix games and linear programmes is established. The book assumes that the reader is familiar with matrix algebra and the background knowledge required is covered in the book, Linear Equations by P.M. Cohn, of this series. In fact the notation used in this text conforms with that intro­ duced by Cohn. The book is based on a course of about 18 lectures given to Mathematics and Physics undergraduates. Several examples are worked out in the text and each chapter is followed by a set of examples. I am grateful to my husband for many valuable suggestions and advice, and also to Professor W. Ledermann, for encourag­ ing me to write this book.

    Abstract: This book contains a rigorous coverage of those topics (and only those topics) that, in the author's judgement, are suitable for inclusion in a first course on Complex Functions. Roughly speaking, these can be summarized as being the things that can be done with Cauchy's integral formula and the residue theorem. On the theoretical side, this includes the basic core of the theory of differentiable complex functions, a theory which is unsurpassed in Mathematics for its cohesion, elegance and wealth of surprises. On the practical side, it includes the computational applications of the residue theorem. Some prominence is given to the latter, because for the more sceptical student they provide the justification for inventing the complex numbers. Analytic continuation and Riemann surfaces form an essentially different chapter of Complex Analysis. A proper treatment is far too sophisticated for a first course, and they are therefore excluded. The aim has been to produce the simplest possible rigorous treatment of the topics discussed. For the programme outlined above, it is quite sufficient to prove Cauchy'S integral theorem for paths in star-shaped open sets, so this is done. No form of the Jordan curve theorem is used anywhere in the book.
