    Abstract: The islands of the Pacific and East Indies made an enormous and fateful impact on the minds of Charles Darwin and Alfred Wallace, the fathers of modem evolutionary theory. Since then island floras and faunas have continued to playa central role in the development of evolutionary, and more recently ecological thought. For much ofthis century island ecology was a descriptive science and a wealth of information has been amassed on patterns of species distributions, on the composition of island floras and faunas, on the classification of islands into types such as oceanic and continental, on the taxonomic description of insular species and sub-species and on the adaptations, often bizarre, of island creatures. However, biologists are not satisfied for long with the mere collection of data and the description of patterns, but seek unifying theories. Island ecology was transformed into a predictive science by the publication, in 1967, of MacArthur and Wilson's Theory of Island Biogeography. This, perhaps the most influential book written on island ecology, has been the stimulus for a generation of theoretical ecologists and gifted field workers. The books listed below in the bibliography will indicate to the reader the vast scope of island ecology and the changes in approach that have taken place over the years.

    Abstract: Vegetation dynamics is an important subject. A knowledge and under­ standing of it is central to the science of vegetation management-in grassland, range and nature reserve management, and in aspects of wildlife management, forestry and agricultural crop production. It is also a large and diffuse subject. In a small book such as this I had to be highly selective, and could not do equal justice to all aspects. I have had therefore to condense many examples, and more regrettably, many arguments. While I have tried to present a broad selection of topics and examples, the content inevitably reflects my own special interests and experience. The study of vegetation and its dynamics does not lend itselfto neat and tidy divisions, and the way of allotting material into different chapters here is arbitrary. I have used Chapter I to introduce a number of ideas, beginning with the nature of vegetation in space, then passing to an introduction to the nature of changes in vegetation with time, in particular those generally known as successions. The book also contains a number of asides to the text's central arguments; I hope the reader finds these interesting rather than disconcerting.

    Abstract: There are good reasons why the subject of electric power engineering, after many years of neglect, is making a comeback in the undergraduate curriculum of many electrical engineering departments. The most obvious is the current public awareness of the "energy crisis. " More fundamental is the concern with social responsibility among college students in general and engineering students in particular. After all, electric power remains one of the cornerstones of our civilization, and the well-publicized problems of ecology, economy, safety, dependability and natural resources management pose ever-growing challenges to the best minds in the engineering community. Before an engineer can successfully involve himself in such problems, he must first be familiar with the main components of electric power systems. This text­ book will assist him in acquiring the necessary familiarity. The course for which this book is mainly intended can be taken by any student who has had some cir­ cuit analysis (using discrete elements, and including sinusoidal steady state) and elementary electromagnetic field theory. Most students taking the course will be in their junior or senior years. Once the course is completed, students may decide to go more deeply into the design and operation of these components and study them on a more advanced level, or they may direct their attention to the problems of the system itself, problems which are only hinted at briefly at various points herein.

    Abstract: Plants, in addition to their role as primary synthesizers of organic com­ pounds, have evolved as selective accumulators of inorganic nutrients from the earth's crust. This ability to mine the physical environment is restricted to green plants and some microorganisms, other life forms being direct1y or indirect1y dependent on this process for their supply of mineral nutrients. The initial accumulation of ions by plants is of ten spatially separated from the photosynthetic parts, necessitating the transport to these parts of the inorganic solutes thus acquired. The requirement for energy-rich materials by the accumulation process is provided by a transport in the opposite direction of organic solutes from the photosynthetic areas. These transport phenomena in plants have been studied at the cellular level, the tissue level, and the whole plant level. The basic problems of analysing the driving forces and the supply of energy for solute transport remain the same for alI systems, but the method of approach and the type of results obtained vary widely with the experimental material employed, reflecting the variation of the solute transporting properties which have se1ectively evolved in response to both internal and external environmental pressures.

    Abstract: between the organ systems of cephalopods and those of less ambitious molluscs. Octopus does, as we would predict, live close to the limits set by its own physiology. The circulation, to take one example, is barely adequate for such an active animal, mainly because of the absence of any system for pack­ aging the blood pigment; haemocyanin in solution is a poor oxygen carrier. Cephalopod blood can transport less than 5 millilitres of oxygen per 100 ml of blood (compared with about 15 vol% in fish) and the whole supercharged system of triple hearts, high blood pressure and pulsating blood vessels succeeds only in returning blood that retains less than 30% of its dissolved oxygen by the time it reaches the gills. This at rest; the effect of exercise is immediate and surprisingly long­ lasting even in octopuses as small as 300 g, which must very swiftly run into oxygen debt when they flee from predators or pursue their prey (Sections 3.2.2, 3.2.4). Digestion, too would seem to be limiting. As with other molluscs, digestion in Octopus is based on secretion­ absorption cycles by a massive diverticulum of the gut, an adequate system in a less hectic past, but scarcely appropriate in a predator that must be an opportunist in the matter of feeding. Octopus feeds mainly at night, and spends a great deal of every day sitting at home.

    Abstract: In a mathematical programming problem, an optimum (maxi­ mum or minimum) of a function is sought, subject to con­ straints on the values of the variables. In the quarter century since G. B. Dantzig introduced the simplex method for linear programming, many real-world problems have been modelled in mathematical programming terms. Such problems often arise in economic planning - such as scheduling industrial production or transportation - but various other problems, such as the optimal control of an interplanetary rocket, are of similar kind. Often the problems involve nonlinear func­ tions, and so need methods more general than linear pro­ gramming. This book presents a unified theory of nonlinear mathe­ matical programming. The same methods and concepts apply equally to 'nonlinear programming' problems with a finite number of variables, and to 'optimal control' problems with e. g. a continuous curve (i. e. infinitely many variables). The underlying ideas of vector space, convex cone, and separating hyperplane are the same, whether the dimension is finite or infinite; and infinite dimension makes very little difference to the proofs. Duality theory - the various nonlinear generaliz­ ations of the well-known duality theorem of linear program­ ming - is found relevant also to optimal control, and the , PREFACE Pontryagin theory for optimal control also illuminates finite dimensional problems. The theory is simplified, and its applicability extended, by using the geometric concept of convex cones, in place of coordinate inequalities.

    Abstract: viii homology groups. A weaker result, sufficient nevertheless for our purposes, is proved in Chapter 5, where the reader will also find some discussion of the need for a more powerful in­ variance theorem and a summary of the proof of such a theorem. Secondly the emphasis in this book is on low-dimensional examples the graphs and surfaces of the title since it is there that geometrical intuition has its roots. The goal of the book is the investigation in Chapter 9 of the properties of graphs in surfaces; some of the problems studied there are mentioned briefly in the Introduction, which contains an in­ formal survey of the material of the book. Many of the results of Chapter 9 do indeed generalize to higher dimensions (and the general machinery of simplicial homology theory is avai1able from earlier chapters) but I have confined myself to one example, namely the theorem that non-orientable closed surfaces do not embed in three-dimensional space. One of the principal results of Chapter 9, a version of Lefschetz duality, certainly generalizes, but for an effective presentation such a gener- ization needs cohomology theory. Apart from a brief mention in connexion with Kirchhoff's laws for an electrical network I do not use any cohomology here. Thirdly there are a number of digressions, whose purpose is rather to illuminate the central argument from a slight dis­ tance, than to contribute materially to its exposition.

    Abstract: Materials Science has now become established as a discipline in its own right as well as being of increasing importance in the fields of Physics, Chemistry and Engineering. To the student meeting this subject for the first time the combination of disciplines which it embraces represents a formidable challenge. He will require to understand the lan­ guage of the physicist and chemist as well as appreciate the practical uses and limita­ tions of solid materials. This book has been written as an introduction to the Physical Properties of Materials with these thoughts in mind. The mathematical content has been limited deliberately and emphasis is placed on providing a sound basis using simplified models. Once these are understood we feel that a mathematical approach is more readily assimilated and for this purpose supplementary reading is suggested. While the authors are deeply aware of the pitfalls in attempting such a treatment this is meant to be an essentially simple book to point the many avenues to be explored. We anticipate that the book will appeal to first and second year degree students in a variety of disciplines and may not prove too difficult for those studying appropriate Higher National Certificate and Diploma courses. Electrical engineers working in the field of materials applications may well find it useful as a guide to modern thinking about materials and their properties. The book begins with an introduction to some basic ideas of modern physics.

    Abstract: The present scientific and technical revolution has brought science into the range of the most effective forces of production. The formula "science= production force" applies also to the social sciences whose explorations of human relationships and drives have reached previously unsuspected depths. Objectives, such as higher living standards and full employment, economic growth and stability, social equity and security, have both called for and provided a basis for the exploitation of possibilities offered by the natural and technical sciences. In today's agriculture, age-old traditions are in the process of disintegra­ tion, but the heredity of a century (or that of even a millennium as in Hungary) does not get dissolved without defending itself. Technical progress and social restratification, the emergence of new scales of values and preferences, the adjustment of the rural communities to their new tasks and conditions - all these have transformed farm operations and farming techniques. But agriculture, even under its revolutionized surface, still hides deep, almost untouched layers. If economists and agriculturalists are perplexed by the multitude and variety of the visible farm problems, there exist many others about which they can only guess, which they must follow up. In formulating and solving these problems, agricultural economists have professional tasks: (1) facilitating the most efficient use of agricultural resources from the standpoint of the national economy, and (2) helping farmers and farm people to attain their stated, socially feasible objectives.

    Abstract: by Ronald Fletcher To devote a volume to Freud in a series on 'The Making of Sociology' might seem, to some readers, very strange. Freud, they might argue, was not only (and very explicitly) a psychologist, but also (and equally explicitly) a clinical psychologist, whose most immediate preoccupation was that of trying to cure the mental illnesses of his patients. Furthermore, he was a psychologist who insisted on relating his theories as closely as possible to biological and physiological facts. All this, of course, is true. But to adopt this view as one which distinctly marks Freud off from sociology is a basic mistake, and one which shows how sadly subjects which were once seen as being essentially interrelated have been forced into false separation by the current vogue of'specialization'-necessary and correct when it is soundly conceived, but intellectually disastrous when it is not. It is worthwhile to recall that all the major thinkers who contributed to the making of sociology-from Comte and Spencer to Ward, Giddings, Tonnies, Durkheim, Hobhouse, Weber, Simmel, Pareto (this could be a very long list I)-were, in fact, convinced about the close relationships between biology, psychology and sociology. The same is true of all the major anthropologists. The simple truth is that all these men were critically and creatively participating in the revolution which was taking place in man's approach to his knowledge of nature, and of his own nature and place within it.

    Abstract: Since the first statement of the aims and methods of the Cambridge Growth Project, which appeared in 1962 as the first number of our former series A Programme for Growth, we have produced a volume on the state ofthe model and on projections derived from it at roughly five year intervals: Exploring 1970 (1965), Exploring 1972 (1970) and now the present book. A comparison of these publications shows the directions in which we have developed our model. First, we have been able to model more parts of the economy and to model them better; and, second, by adopting a targets-and-instruments approach, we have been able to tackle questions of policy. As a consequence of the first of these improvements, the model has become more closely knit and variables which were previously exogenous have become endogenous; and, as a consequence of the second, the model has become less rigid and can be used to suggest policies for correcting some ofthe undesir­ able features that emerge from the projections.

    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.

    Abstract: This book is primarily intended to assist candidates studying geology for the Ordinary Level of G.c.E., and examinations of comparable standard, but it should also be found useful by the" reader requiring a rapid conspectus of the geological history of Britain, and as forming a basis for more advanced work. 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: 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: 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: 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: 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: 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: 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.
