Abstract: A very large number of organo derivatives is formed by the Group IV ele­ ments silicon, germanium, tin, and lead. In comparing the general properties of these elements, Table 1. 1 shows that the first ionization energies decrease (though not in a regular way) with increase in size and atomic number, con­ sistent with the general increase in metallic character of the elements. Electro­ negativity values (which have been the subject of considerable controversy) show no clear trend. Although purely inorganic compounds of tin(n) and leaden) are well known, almost all organo Group IV derivatives show an oxidation state of IV. Bonds to carbon become weaker on passing from silicon to lead, as do the element-element bonds themselves. With any particular element M (M = Si, Ge, Sn, or Pb), there is a small decrease in bond energy in the order: M-Ph 〉 M - Me 〉 M - Et. Although accurate data for organo derivatives are lacking, strengths of bonds to other elements probably decrease in the order: M-F〉 M-O 〉 M-CI 〉 M-H ~ M-N ~ M-S ~ M-Br 〉 M-I, while for a particular element X, the order is: Si-X 〉 Ge-X 〉 Sn-X 〉 Pb-X. It is therefore understandable that reactions leading to Si-F, Si-O, or Si-CI bonds are especially favoured in a thermodynamic sense.

Abstract: Our aim in writing this book is to try to show how igneous rocks can be persuaded to reveal some ofthe secrets of their origins. The data of igneous rocks consist of field relations, texture, mineralogy, and geochemistry. Additionally, experimental petrology tells us how igneous systems might be expected to behave. Working on this material we attempt to show how hypotheses concerning the origins and evolution of magmas are proposed and tested, and thus illuminate the interesting and fundamental problems of petrogenesis. The book assumes a modest knowledge of basic petro­ graphy, mineralogy, classification, and regional igneous geology. It has a role complementary to various established texts, several of which are descriptively good and give wide coverage and evaluation of petrogenetic ideas in various degrees of detail. Existing texts do not on the whole, however, deal with methodology, though this is one of the more important aspects of the subject. At first sight it may appear that the current work is a guidebook for the prospective research worker and thus has little relevance for the non-specialist student of geology. We hope this will prove to be far from the case. The methodological approach has an inherent interest because it can provide the reader with problems he can solve for himself, and as an almost incidental consequence he will acquire a satisfying understanding.

Abstract: Shuichi Kato's two-volume history of Japanese literature is impressive for its critical and comparative grasp as well as for its historical scholarship. It is also a unique contribution to the subject insofar as it incorporates the vast spread of kambun (classic Chinese) literature written by Japanese authors. By moving beyond the discussion of literary forms and style into the social background which has shaped the works, Professor Kato provides the first real history of Japanese literature in its context; in fact, given the importance of literature in Japanese cultural history in general, Professor Kato's work could equally be viewed as a study of Japan's intellectual history through literature

Abstract: This advanced text focuses on a set of key themes and issues of particular relevance and topicality in understanding contemporary Chinese politics, economy and society. Following an overview of the historical background - with a particular emphasis on economic developments - it provides a comprehensive and detailed account of rural and urban policy, the law and policing, intellectual life, families and gender relations, and minority nationalities in China today

Abstract: Learn the laws of inheritance and teach them to the people; for they are one half of useful knowledge. t·1ohannned (Fyzee 1955: 329) When the prophet created this aphorism he had in mind the rules of in­ heritance law revealed to him by Allah. We could apply it to social an­ thropology as well sincethe inheritance of property and the succession to positions of socio-political authority are among the most important elements of social organization. They are the vehicles of continuity which maintain property and authority through time. In many societies, and particularly in those generally studied by anthropologists, inherit­ ance and succession are closely interconnected with kinship and descent and provide the economic and political substance for the existence and continuity of kinship- or descent-based social groups. They are, as it were, the flesh on the bare bones of kinship relations. The importance of inheritance has, of course, not escaped the notice of social and legal anthropologists, and in recent years several studies have ably demonstrated the point (Radcliffe-Brown 1952, Goodenough 1951, Leach 1961 b, Goody 1962, Lloyd 1962, Gray and Gulliver (eds. ) 1964, Derrett (ed. ) 1965, Gluckman 1972, Moore 1969, Burling 1974). Yet in general, property and inheritance have rather been treated as an appendix to economic and kinship studies.

Abstract: In 1972, Dr Margaret Pollak published her book Today's Three-Year­ Oids in London. This was a sensitive study of family life and the social environment of a large number of London children, together with an account of their developmental assessment by various test methods. She showed that variations of developmental performances were more closely related to the quality of family life than to social and economic factors. Dr Pollak has now re-investigated the same children at nine years of age and this book is a record of her findings. The differences in development which were noted at three years of age remain in the older children. Those children who, at three years of age, were underachievers, particularly in verbal and adaptive abilities, are the children who, at nine years, can still be identified by lower achieve­ ment at school. These results must be of important relevance to educationalists, and all concerned with the psychologists as well as to paediatricians welfare of children. We must all be disturbed by the failure of any children in our urban city centres to benefit from education and our anxieties must be heightened if, amongst the underachievers, there are particular groups who can be identified by their ethnic identities. In Britain, education in school occupies a relatively small part of a child's life. Dr Pollak has identified some of the factors in a child's wider experience and, especially, in the total home environment which are associated with the persistence of inferior performance.

Abstract: The Handbook of Electronics Formulas, Symbols and Defini­ tions has been compiled for engineers, technicians, armed forces personnel, commercial operators, students, hobbyists, and all others who have some knowledge of electronic terms, symbols, and theory. The author's intention has been to provide: A small, light reference book that may be easily carried in an attache case or kept in a desk drawer for easy access. A source for the majority of all electronic formulas, sym­ bols, and definitions needed or desired for today's passive and active analog circuit technology. A format in which a desired formula may be located almost instantly without the use of an index, in the desired trans­ position, and in sufficiently parenthesized linear form for direct use with any scientific calculator. Sufficient information, alternate methods, approximations, schematic diagrams, and/or footnotes in such a manner so that technicians and hobbyists may understand and use the majority of the formulas, and that is acceptable and equally useful to engineers and others very knowledgeable in the field. iii ACKNOWLEDGMENTS Much of the material is this Handbook is based upon a small loose-leaf notebook containing formulas and other reference material compiled over many years. With the passage of time, the sources of this material have become unknown. It is impos­ sible therefore to list and give the proper credit.

Abstract: When Wolfgang Friedmann died there was a great outpouring of grief, affection and admiration from his friends all over the world. These deeply felt sentiments were soon channelled into a number of projects to honor him. The initiative towards the preparation of this volume in tribute to Wolfgang Friedmann was taken by his colleague, Hans Smit, of Columbia University, who also arranged for its publication. Judge Philip C. Jessup was the chairman, and Professors John N. Hazard, Louis Henkin, Oliver Lissitzyn, Willis L. M. Reese and Hans Smit of Columbia University Law School, A. A. Fatouros of Indiana University Law School (Bloomington), and Gabriel M. Wilner of the University of Georgia Law School were members of the editorial committee. The authors of the essays are a group of distinguished legal scholars from many countries and who hold widely diverse views. All of them had many ties with Professor Friedmann, including those of friendship and shared interest in problems that were of the greatest concern to him. The number of eminent jurists from countries around the world, and particularly from the United States, who would have wished to participate in this tribute to Wolfgang Friedmann is large; however, several important considerations made it necessary to limit the number of contributions. Thus, for example, the work of several members of the editorial committee is not represented in the volume.

Abstract: More than a decade has passed since economist Richard N. Cooper reflected upon the trend toward increasing economic interdependence in the international community: During the past decade there has been a strong trend toward economic interdependence among the industrial countries. This growing interdependence makes the successful pursuit of national economic objectives much more difficult. Broadly speaking, increas­ ing interdependence complicates the pursuit of national objectives in three ways. First, it increases the number and magnitude of the disturbances to which each country's balance of payments is subjected, and this in turn diverts policy attention and instruments of policy to the restoration of external balance. Second, it slows down the process by which national authorities, each acting on its own, are able to reach their domestic objectives. Third, the response to greater integration can involve the community of nations in counter-acting motions which leave all countries worse off than they need be . . . J Nothing has occured in the 1970s to suggest that Cooper's assessment is inaccurate. Indeed, the process which he identified has accelerated. By the mid-1970s, if one is to mention but one example, exports accounted for twenty per cent of the combined gross national product of the Member States of the European Communities, and exports provided seven per cent of the 2 gross national product of the United States.

Abstract: This is a collection of original papers, each by an expert in his field. They deal with different sectors of recent geophysical development. It may be, at first, difficult to see what else unites them, and how these several technologies can contribute to an integrated exploration process. What brings these writers together is that they have all contributed to the improvement of what comes to the eye of the geophysical interpreter. Some of the improvement is achieved at the data-gathering stage, some of it in processing, and in presentation. For all of this improvement interpreters in general are most grateful. The editor is appreciative in a quite personal way, not only of the advances in technology, but also of the effort in writing which has been made by these busy contributors, and so created this collection. Something can be said here about interpretation and the environment in which it is carried out, since it represents the field where the results of these technical developments are ultimately tested. In the commercial world it is from the geophysical interpreter that management learns the results of a large sector of exploration expenditure, and learns them in a form on which still larger expenditures on later phases of exploration can be based.

Abstract: To English-speaking historians, the author of this book, a Dutchman who for many years now finds his base at the University of Florida, became well known when his The Dutch in the Caribbean and on the Wild Coast, 158~I680 was published in 1972. At that time Professor Goslinga, who prior to his academic career in the United States, lived for an extended period in Cura~ao, Netherlands Antilles, had already acquired a solid reputation among Dutch Caribbeanists by his manifold publications on social, political and maritime aspects of Dutch West Indian history. By his training, interests and present position, Dr. Goslinga would seem to me to be singularly well-equipped to write a comprehensive history - geared to an English-speaking university public - of what was once known as the Netherlands West Indies. The present book is the product of this professional equipment and of his long teaching experience. It should go a long way in filling the old and wide gap in historical information on this part of the former Dutch empire, and I hope an equally wide but younger audience will appreciate it.

Abstract: For some years I have felt there was a need for a single, comprehen­ sive, reference book on exploration geology. Numerous textbooks are available on subjects such as geophysical prospecting, exploration geochemistry, mining geology, photogeology and general economic geology, but, for the geologist working in mineral exploration, who does not require a specialist's knowledge, a general book on explora­ tion techniques is needed. Many undergraduate university courses tend to neglect economic geology and few deal with the more prac­ tical aspects in any detail. Graduate geologists embarking on a career in economic geology or mineral exploration are therefore often poorly equipped and have to learn a considerable amount 'on the job'. By providing a book that includes material which can be found in some of the standard texts together with a number of practical aspects not to be found elsewhere, I hope that both recent graduates and more experienced exploration geologists will find it a useful reference work and manual. In addition, students of economic geology and personnel working in related fields in the mining and mineral extraction in­ dustries will find it informative. J. H. REEDMAN v Acknowledgements The author would like to thank Dr K. Fletcher, geochemist with the Department of Geology, University of British Columbia, and Kari Savario, geophysicist with Finnish Technical Aid to Zambia, for reading the original drafts and offering constructive criticism and advice on the chapters on geochemical and geophysical prospecting respectively.

Abstract: The present book is an exp]oration of some basic issues of Kant's moral phi­ losophy. The point of departure is the concept offreedom and the self-legisla­ tion of reason. Since self-Iegislation is expressed in the sphere of practice or morality, it is meant to overcome some of the vulnerable aspects of Kant's theoretical philosophy, namely that which Kant himself pointed to and called the 'lucky chance,' in so far as the application of reason to sensuous data is concerned. The book attempts to show that Kant's practical or moral philosophy faces questions which are parallel to those he faced in the sphere ofhis theore­ tical philosophy. The problematic situation of realization of practice is parallel to the problematic situation of application of theory. It is in the line of the problems emerging from Kant's practical philosophy that the present book deals with some of Kant's minor writings, or less-known ones, in­ cluding his writings in the sphere of politics, history and education. The limitations of self-Iegislation - this is the theme of the book. The book is parallel to the author's previous one on Kant: 'Experience and its Systema­ tization - Studies in Kant" (Nijhoff, 1965, 2nd edition 1973), as well as to: "From Substance to Subject -Studies in Hegel" (Nijhoff, 1974).

Abstract: Since publication of the first English edition this book has become the standard reference work on paint film defects throughout the world. The very considerable advances in coatings technology since the second English edition was published in 1965 have necessitated a revision of the book, a task which from the outset was recognized as formidable. The very wide field to be covered required specialist knowledge as well as wide experience, and we were fortunate in being able to enlist the services of a group of contributors who were well qualified for the task. Due to his advancing age Mr Manfred Hess, the originator of this work, felt unable to take an active part in the preparation of the new edition. He entrusted not only a large part of the necessarily extensive revision of the text, but also the editorial work, the planning and compilation of the index to us jointly. A variety of causes has prevented the main contributors to the second edition, Mr W.A. Edwards and Mr T .W. Wilkinson, from revising their sections. Nevertheless, much of what they and others have contributed to previous editions has enabled us to build on valuable foundations. Much new material has been added; the illustrations section has been expanded and enhanced by the addition of several colour plates. Mr S.T. Harris revised the sections concerned with industrial finishes and in particular powder coatings, and Dr T.A. Banfield contributed the sections on marine paints and compositions.

Abstract: A system of philosophy of the sort presented in this and the following volumes begins with logic. Philosophy properly speaking is characterized by the kind oflogic it employs, for what it employs it assumes, however silently; and what it assumes it presupposes. The logic stands behind the ontology and is, so to speak, metaphysically prior. One word of caution. The philosophical aspects of logic have lagged behind the mathematical aspects in point of view of interest and develop­ ment. The work of N. Rescher and others have gone a long way to correct this. However, their work on philosophical logic has been more concerned with the logical than with the philosophical aspects. I have in mind another approach, one that would call attention to the ontological (systematic meta­ physics) or metaphysical (critical ontology) aspects, whichever term you prefer. It is this approach which I have pursued in the following chapters. Since together they stand at the head of a system of philosophy which has been developed in some seventeen books, a system which ranges over all of the topics of philosophy, the chosen approach can be seen as the necessary one.

Abstract: Electronics is essentially an experimental subject and enables a wealth of experimental work to be undertaken at relatively low cost. In any modestly equipped electrical engineering or physics laboratory. it is possible to plan interesting experiments to study active and passive com­ ponents, basic circuit functions, modular encapsulations and monolithic integrated circuits. The work may range from the formal investigation of a device new to the student to the design and construction of quite advanced, modern measurement and control systems. There are few books which guide experimental work in electronics. This text aims to rectify this by giving detailed descriptions of a series of experiments all of which have been thoroughly tested by students in physics, electronics, electrical engineering and instrumentation at The Polytechnic of Central London. Moreover, several of these experiments would seem to be appropriate for the current development of interest in courses in electronics in schools because several of them have been undertaken with considerable success by first-year sixth-form students who have come to Central London for special courses. They would also assist an introductory course in electronics for students from other disciplines and have been tried out in this way at The Polytechnic.

Abstract: "Dialectic" is a fulcrum word. Aristotle attacked this belief, saying that the dialectic was only suitable for some purpose- to enquire into men's beliefs, to arrive at truths about eternal forms of things, known as Ideas, which were fixed and un­ changing and constituted reality for Plato. Aristotle said there is also the method of science, or "physical" method, which observes physical facts and arrives at truths about substances, which undergo change. This duality ofform and substance and the scientific method of arriving at facts about substances were central to Aristotle's philosophy. Thus the dethronement of dialectic from what Socrates and Plato held it to be was ab­ solutely essential for Aristotle, and "dialectic" was and still is a fulcrum word . . . I think it was Coleridge who said everyone is either a Plato­ nist or an Aristotelian . . . Plato is the essential Buddha-seeker who appears again and again in each generation, moving on­ ward and upward toward the "one. " Aristotle is the eternal motorcycle mechanic who prefers the "many. " R.

Abstract: 1 Introduction -- 2 Lettuce -- 3 Celery -- 4 Cabbage -- 5 Endive and Chicory -- 6 Spinach -- 7 Lesser Salad Vegetables.

Abstract: Leafy salad vegetables are among the most universally used vegetable crops grown today. Their prominence as important crops has been heightened through the last several decades due to an awareness on the part of consumers of the nutrient, and other obvious values they offer to the diet as "fresh greens" which, at least in the United States, have become a daily table staple. As a result, acreage planted to leafy salad vegetable crops has expanded to a remarkable degree over the past few decades, making these crops an important segment of the agricultural and marketing industries. Published information on leafy salad vegetables has been-and is­ widespread and scattered. This book brings together all up-to-date information and is amply referenced throughout for further study and information. Similarities and differences among the species are discussed and provide insight into the place these species hold in the world cropping system and in the human diet. This approach in text organiza­ tion was made in an effort to be helpful to the widest type of readership: professional researchers and teachers, graduate and undergraduate stu­ dents, extension workers, farmers and other members of the horticultural community, and, perhaps, even lay readers who are the ultimate consumers.

Abstract: My first thanks must go to the Electors to Ford's Lectureship in English History in the University of Oxford, who honoured me with the invitation to discharge that formidable responsibility in 1969, generously interpreting the statute so as to allow me to deal with a subject which contained nearly as much Netherlands as it did English history. To Hugh Trevor-Roper, Regius Professor of Modern History in the University of Oxford, and his fellow­ Electors, I am grateful for much encouragement, guidance and hospitality. The colleagues and pupils upon whom I have from time to time inflicted discussion of problems arising from my subject are far too numerous to be thanked individually. Two must nevertheless be singled out. Vivian Fisher of Jesus College, Cambridge, very kindly read the completed manuscript, and I have benefited by a number of characteristically penetrating comments and suggestions which he made. Geoffrey Parker, Fellow of Christ's College, generously allowed me to make use of his unique knowledge of the Spanish, French and Italian archives to check and supplement my own information. I am deeply grateful to both. Finally, it will be evident that quite apart from my own researches these lectures owe a heavy debt to many scholars, Dutch, Belgian, American and British especially, who have worked in this or related fields of inquiry. I am not less indebted to those from whose interpretations I have ventured to differ than to those with whom I have found myself in agreement.

Abstract: The engineering designer is always limited by the properties of available materials. Some properties are critically affected by variations in com­ position, in state or in testing conditions, while others are much less so. The engineer must know this if he is to make intelligent use of the data on properties of materials that he finds in handbooks and tables, and if he is to exploit successfully new materials as they become available. He can only be aware of these limitations if he understands how pro­ perties depend on structure at the atomic, molecular, microscopic and macroscopic levels. Inculcating this awareness is one of the chief aims of the book, which is based on a successful course designed to give university engineering students the necessary basic knowledge of these various levels. The material is equivalent to a course of about eighty to a hundred lectures. In the first part of the book the topics covered are mainly fundamental physics. The structure of the atom, considered in non-wave-mechanical terms, leads to the nature of interatomic forces and aggregations of atoms in the three forms-gases, liquids and solids. Sufficient crystallography is discussed to facilitate an understanding of the mechanical behaviour of the crystals. The band theory of solids is not included, but the basic concepts which form a preliminary to the theory-energy levels of electrons in an atom, Pauli's exclusion principle, and so on-are dealt with.

Abstract: In compiling this volume the editors have aimed to gather together, in one volume, as many of the important political facts as possible for a critical period of European history. In addition this book has also been designed as a companion volume to the existing European Political Facts 1918-1973 and to the forthcoming European Political Facts 1789-1848. Once again the editors have taken all the countries of Europe, from Portugal and Spain to Tsarist Russia and the Ottoman Empire ✅.

Abstract: From 1970 to 1977 a major project to uncover source material for students of contemporary British history and politics was undertaken at the British Library of Political and Economic Science. Fiananced by the Social Science Research Council, and under the direction of Dr Chris Cook, this project has attempted a unique and systematic operation to locate, and then to make readily available, those archives that provide the indispensable source material for the contemporary historian. This volume (the fifth in the series) provides a guide to the papers of propagandists who were influential in British public life. Included in this volume are the papers of such persons as newspaper editors, leading economists, social reformers, socialist thinkers, trade unionists, industrialists and a variety of theologians and philanthropists. In all, this volume not only completes the findings of the project but opens up the archive sources of a hitherto neglected area of research into contemporary social and political history

Abstract: This book was written to provide an integrated account of barley, induding its cultivation, nature and uses. An attempt has been made to cut across the unjustified and obstructive divisions between pure science, applied science, technology, botany, biochemistry, agronomy, and so on. Limitations of space preclude the use of more illustrative material or references, or even complete accounts of various topics. However sufficient information is given to enable the reader to understand the general principles and to find his or her way readily into the literature to obtain further information. Emphasis has been placed on general principles rather than details. In becoming familiar with the literature one becomes acquainted with the effects of the cereal or religion, the English language and the development of agriculture and biochemistry. The comparison between 'parallel literatures' is often stimulating also. For example one is forced to conclude that many of the agricultural problems of poor 'seed vigour' would be overcome if seedsmen used the maltsters techniques for breaking dormancy and speeding 'post-harvest maturation'. Barley is the world's fourth most important cereal after wheat, rice, and maize. It is the most widely cultivated, being grown from the equator to 700N (Scandinavia), from the humid regions of Europe and Japan to the Saharan and Asiatic Oases, and from below sea level in Palestine to high up mountains in the Himalayas, E. Africa and S. America. Some­ where in the world it is being sown or harvested at every time of the year.
