Taschenbuch. Condizione: Neu. Neuware - Writing this second edition of Biochemical Genetics proved to be more difficult than I had anticipated. The fixed format of the series meant that the addition of new material was made possible only by the dele tion of old. Since the book is intended for a student audience, I have retained the historical approach of the first edition and added new material only when it demonstrates a principle more effectively. At the time of writing, we are witnessing an information explosion resulting from the application of recombinant DNA technology to all manner of problems. I have added a sixth chapter indicating the impact of this work on our concepts of gene structure. I should like to thank Ed Byard, Bill Evans, Charles Schorn and Ed Ward, colleagues in the Biology Department at the University of Winnipeg, and Andrew Spence, a student in the department, for their comments on the manuscript of the second edition, and to reiterate my thanks to all those in the Department of Genetics at the University of Sheffield who commented on the first edition.

Buch. Condizione: Neu. Neuware - The present volume is a product of an international research program 'Foundations of Science and Ethics', launched in 1976 by the Inter University Centre of Post-Graduate Studies, Dubrovnik, Yugoslavia, with the financial support of the V olkswagen Foundation. According to the outline ofthe program, formulated in 1976 by a committee consisting of Professors Dagfinn F~llesdal, Rudolf Haller (coordinator), Lorenz Kruger, Karel Lambert, Keith Lehrer, Kuno Lorenz, Gunther Patzig, Ivan Supek and Paul Weingartner, its general purpose was to investigate the interplay of various internal and external factors in the development of science. Generous financial support from the Volkswagen Foundation made it possible to plan four annual conferences, the first of which was held in Dubrovnik on March 6-12, 1978. This volume contains the majority of the papers presented in the first Dubrovnik conference; the main theme of this conference was 'Rationality in Science and Ethics' (Some of the papers appear here in a thoroughly revised form. ) Further results of the research program will be discussed in three other conferences, to be held in Dubrovnik in 1979-1981; the papers presented in these conferences will be published separately. Professor Rudolf Haller of the University of Graz assumed the burden of the practical planning and organization of the first conference (as well as that of the other three conferences). I wish to thank Professor Haller on behalf of all participants for carrying out this demanding and time-consuming task.

Buch. Condizione: Neu. Neuware - Why should the story of a woman's role in the development of a scientific theory be written Is it to celebrate, as some have done, the heroism of a woman's struggle in a man's world Or is it, rather~to demonstrate that gender is irrelevant to the march of scientific ideas This book hopes to do neither. Rather, it intends to do justice both to the professional life of a woman in science and to the development of the theory with which she was engaged. Technically, this essay centers on Sophie Germain's analysis of the modes of vibration of elastic surfaces, work which won a competition set by the French Academy of Sciences in 1809. It also evaluates related work on the mathematical theory of elasticity done by men of the Academy. Biographically, it is about a woman who believed in the greatness of science and strove, with some measure of success, to participate in that noble, but wholly male-dominated, enterprise. It explores her failures, analyzes her success, and describes how the members of the Parisian scientific community dealt with her offerings, contributions and demands.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The year 1978 marked the thirtieth anniversary of Professor C. J. Ham son's 'Summer course for foreign lawyers' and of his untiring efforts not only to introduce the civil lawyer to the mysteries of the Common law but also to bring closer together lawyers from both sides of the Channel. The same year saw the beginning of the 'Cambridge-Tilburg Law Lectures' wh ich developed indirectIy from the 'Summer course' and which seek to achieve similar aims by different methods. The idea of inviting two Cambridge scholars to assist their Dutch col leagues in the teaching of the Common law as a regular option for under graduate studies is novel and, to judge from first reactions, has so far been successful. The immediate objects are to achieve closer links be tween lawyer and Civillawyer; to encourage the further systematic teach ing of the Common law; and to produce aseries of lectures, two of which will be published annually in the hope that they may be of inter est to a wider public. 84 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Wilhelm His, one of the founders of developmental neurobiology, was convinced 'that the processes of generation and development obey fundamental and simple laws and submit to the general laws of nature' (His 1901). Therefore, we should be able to find immediate conditions, dependencies and rules determining the de velopment of an organic form. With this in mind, His (1874) defined the task of embryology as follows: 'Developmental biology is essentially a physiological science; it has not only to describe how each individual form develops from the egg, it has to derive this development in such a way that each developmental stage together with all its specialities appears as a necessary consequence of the immediately pre ceding stage . . . Only if developmental biology has given a perfect physiological deriva tion for any given form, has it the right to say that it has explained this individual form. ' The ultimate aim of a physiological derivation would be that laws of growth valid for organic ,beings can be expressed as mathematical formulae (His 1874). To exemplify this, he formulated a universal and purely formal law of growth in mathematical terms making the comment: 'I now suggest that the body form follows immediately from germinal growth and can be derived from the given germinal form according to the laws of growth. My interest is, therefore, firstly to detect the law of growth empirically and secondly to derive consecutive forms of the developing or ganism by applying this law. 104 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -These Proceedings have been assembled from papers presented at the Conference on Models of Biological Growth and Spread, held at the German Cancer Research Centre Heidelberg and at the Institute of Applied Mathematics of the University of Heidelberg, July 16-21, 1979. The main theme of the conference was the mathematical representation of biolog ical populations with an underlying spatial structure. An important feature of such populations is that they and/or their individual com ponents may interact with each other. Such interactions may be due to external disturbances, internal regulatory factors or a combination of both. Many biological phenomena and processes including embryogenesis, cell growth, chemotaxis, cell adhesion, carcinogenesis, and the spread of an epidemic or of an advantageous gene can be studied in this con text. Thus, problems of particular importance in medicine (human and veterinary), agriculture, ecology, etc. may be taken into consideration and a deeper insight gained by utilizing (more) realistic mathematical models. Since the intrinsic biological mechanisms may differ considerably from each other, a great variety of mathematical approaches, theories and techniques is required. The aims of the conference were (i) To provide an overview of the most important biological aspects. (ii) To survey and analyse possible stochastic and deterministic approaches. (iii) To encourage new research by bringing together mathematicians interested in problems of a biological nature and scientists actively engaged in developing mathematical models in biology. 528 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Isoenzymes were 'discovered' 20 years ago and were at first regarded as interesting but rare occurrences. Since then a wealth of information on enzyme heterogeneity has accrued and it now seems likely that at least half of all enzymes exist as isoenzymes. This is important in many areas of biological and medical science. Thus isoenzyme studies have provided the main experimental substance for the neutral drift controversy in genetics and evolution; they have greatly extended our understanding of metabolic regulation not only in animals but also in bacteria and plants; their existence has made available a multitude of highly sensitive markers for the study of differentiation and development, as well as providing indices of aberrant gene expression in carcinogenesis and other pathological processes. Iso enzymes are also being used increasingly in diagnostic clinical bio chemistry. It is surprising that this phenomenon which affects such a high pro portion of enzymes and is clearly important in biochemistry should receive such scant attention in the standard textbooks of that subject, the formal treatment of isoenzymology in these rarely exceeding one or two pages. This may be because the 'pure biochemist' has tended to regard variation in enzyme properties between tissues more as an unwanted complication than as a potential source of insight into diversity of biological function. 84 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -While there are many books available on methods of organic and biochemical analysis, the majority are either primarily concerned with the application of a particular technique (e.g. paper chromatography) or have been written for an audience of chemists or for biochemists work ing mainly with animaltissues. Thus, no simple guide to modern metho ds of plant analysis exists and the purpose of the present volume is to fill this gap. It is primarily intended for students in the plant sciences, who have a botanical or a general biological background. It should also be of value to students in biochemistry, pharmacognosy, food science and 'natural products' organic chemistry. Most books on chromatography, while admirably covering the needs of research workers, tend to overwhelm the student with long lists of solvent systems and spray reagents that can be applied to each class of organic constituent. The intention here is to simplify the situation by listing only a few specially recommended techniques that have wide currency in phytochemical laboratories. Sufficient details are provided to allow the student to use the techniques for themselves and most sections contain some introductory practical experiments which can be used in classwork. 292 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Combinatorics may very loosely be described as that branch of mathematics which is concerned with the problems of arranging objects in accordance with various imposed constraints. It covers a wide range of ideas and because of its fundamental nature it has applications throughout mathematics. Among the well-established areas of combinatorics may now be included the studies of graphs and networks, block designs, games, transversals, and enumeration problem s concerning permutations and combinations, from which the subject earned its title, as weil as the theory of independence spaces (or matroids). Along this broad front,various central themes link together the very diverse ideas. The theme which we introduce in this book is that of the abstract concept of independence. Here the reason for the abstraction is to unify; and, as we sh all see, this unification pays off handsomely with applications and illuminating sidelights in a wide variety of combinatorial situations. The study of combinatorics in general, and independence theory in particular, accounts for a considerable amount of space in the mathematical journais. For the most part, however, the books on abstract independence so far written are at an advanced level, whereas the purpose of our short book is to provide an elementary in troduction to the subject. 160 pp. Englisch.

As this difficult genus was never before monographed, a revisional study was much needed. The data presented are mainly based on the study of herbarium specimens and in some cases of living ones. The picture was completed, as far as possible, with data from various literature sources. A short survey is given of the taxonomic history of Origanum, which goes back as far as Linnaeus, and shows that genus and species concepts of various authors have much differed. A morphological outline of Origanum is given, from which it can be concluded that most generic characters are rather variable. Origanum is characterized in the following ways. Medium sized, subshrubby Labiatae, rich in volatile oils, with subsessile, ovate, glandular punctate leaves and paniculate inflorescences; few flo wered verticillasters arranged in (dense) spikes with distinct, often coloured, bracts; calyces variable: 5-toothed, subregular or 2-lipped or I-lipped, with developed or reduced teeth; corollas 2-lipped, sometimes saccate or flattened. 168 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In this book we present a largely biochemical look at the metals of life and their functions, which we hope will be of interest to chemists and biologists as well as biochemists. The field of 'inorganic bio chemistry' is one of rapid change. Recent developments in our know ledge of the activity of calcium, and of the iron-sulphur proteins, are two examples, and increasing attention is being paid to non-metals as well [3]. For reasons of space, we shall restrict ourselves to the normal biological activities of metals. We must ignore, on the one hand, the gross physiological effects of metal deficiency or toxicity, and on the other, the many model studies which have been stimulated by the unusual properties of metals in biological systems. Usually the synthesis of model metal compounds follows rather than anticipates the dis covery of novel biological configurations. However, such studies give us a firm basis for an understanding of the biological systems, and sometimes answer questions that cannot be tackled any other way (for instance, what is the net charge on an iron-sulphur cluster ). As a result, we can refer to new and interesting information on the metals oflife at a chemical level. We gratefully acknowledge the help of Professor P. Banks and Dr D. Fenton who have read and criticized the manuscript, though any errors or misconceptions remain our own responsibility. We thank Mr P. Elliot for preparing Fig. 5.2. 84 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The emergence of Mossbauer spectroscopy as an important experi mental technique for the study of solids has resulted in a wide range of applications in chemistry, physics, metallurgy and biophysics. This book is intended to summarize the elementary principles of the technique at a level appropriate to the advanced student or experienced chemist requiring a moderately comprehensive but basically non-mathematical introduction. Thus the major part of the book is concerned with the practical applications of Mossbauer spectroscopy, using carefully selected examples to illustrate the concepts. The references cited and the bibliography are intended to provide a bridge to the main literature for those who subseouent ly require a deeper knowledge. The text is complementary to the longer research monograph, 'Mossbauer Spectroscopy', which was written a few years ago in co-authorship with Professor N.N. Greenwood, and to whom I am deeply indebted for reading the preliminary draft of the present volume. I also wish to thank my many colleagues over the past ten years, and in particular Dr. R. Greatrex, for the many stimu lating discussions which we have had together. However my greatest debt is to my wife, who not only had to tolerate my eccen tricities during the gestation period, but being a chemist herself was also able to provide much useful criticism of the penultima te draft. 264 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Informal discussions in 1977 among a number of scientists asso ciated with solar and interplanetary physics revealed a need for a dialogue between the two often-divergent groups. It was clear that the latter group was dependent essentially on the sun for its raison d'etre. On the other hand it was also clear that the former group could benefit in its search for insight vis-a-vis solar activity by looking beyond the shell of the inner corona. Needless to add that the combined solar/interplanetary topic is relevant to astrophysics when one considers stellar winds and binary star flows. It was felt, there fore, that a symposium was essential to bring together, for the first time, leading solar and interplanetary physicists from the interna tional community to discuss and record herein their own research. The fundamental physical processes underlying our own capricious star's activity can be understood only by the coupling of solar and interplan etary topics in an intimate observational and theoretical structure. This book, intended for active research scientists and advanced grad uate students, is an important step in this direction. The background of solar and interplanetary dynamics is provided in Part I (The Life History of Coronal Structures and Fields) and Part II (Coronal and Interplanetary Responses to Long Time Scale Phenomena). 580 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book has grown from nine hours oflectures, and about the same time in tutorial classes, that attempt to give first-year students of biology some understanding of statistics. I am convinced that such a short course should not be mathematical (though it can employ basic mathematical symbolism), and that it should give students an appreciation of statistical argument, even though this limits the amount of detailed instruction in techniques of analysis that can be included. A statistical cookery book would have been easier to write and much easier to read, but lacking in true educational content. I am more concerned to show 'why' than to present methods and rules. A further constraint, that of remaining within a reasonable price range, prevents reiteration of explanations: the reader is expected to remember what he has read, for he will not find standard terms and ideas explained afresh on each occasion of use. Many books that introduce statistics to biologists blur distinctions and evade logical issues, for example by failing to emphasize the distinction between a parameter and an estimator from a sample or by neglecting the role of randomization. On this, I aim to be un compromisingly correct - at least until reviewers point out my errors - but to do so through realistic examples rather than abstract symbolism. 176 pp. Englisch.

Oswaldo Chateaubriand, Ronald Haver, Paul Horwich, Bernie Katz, Norman Kretzmann, Stanley Martens, Stephen Pink, Michael Stokes, Eleanor Stump, Bill Ulrich, Celia Wolf, and a lot of other people questioned or criticized or helped reformulate one or another of the arguments and interpretations along the way. In spite of (maybe partly because of) their efforts, the book is full of mistakes. At least, induction over previous drafts indicates that irresistibly. But I do not, right now, know of any particular mistakes. All but a couple of the translations are mine (the exceptions are noted). That is not because existing translations are bad, but because some uniformity was essential. The translations often make unpleasant reading. So, often, does Aristotle; I have tried to be literal. A text and translation of the passage on which the book centers is in Appendix III. Footnotes cite literature by author and (sometimes abbreviated) title. Details are in the bibliography. I do not profess to have covered all the literature. An enormous amount of editorial work was done by Margaret Mundy. She was not able to undo the errors that remain. In particular, the footnotes are often numbered oddly: '4', '4a', '4b', etc. 204 pp. Englisch.
