Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The philosophical papers comprising this volume range from process metaphysics and theology, through the phenomenological study of intentionality, to the foundations of geometry and of the system of real numbers. New light, it is thought, is shed on all these topics, some of them being of the highest interest and under intensive investigation in contemporary philosophical discussion. Metaphysi cians, process theologians, semanticists, theorists of knowledge, phenomenologists, and philosophers of mathematics will thus find in this book, it is hoped, helpful materials and methods. The categoreal scheme of Whitehead's Process and Reality is discussed rather fully from a logical point of view in the first paper [I] in the light of the author's previous work on the logico-metaphysical theory of events. The clarification that results is thought to provide a new depth and precision to the problem of interpreting one of the most difficult books in the recent history of metaphysics and cosmol ogy. A detailed examination of some aspects of Hartshorne's recent Creative Synthesis and Philosophic Method is given in II. This book is perhaps the most significant work on process philosophy since Process and Reality itself, and its logical underpinnings thus merit a full critical discussion. 168 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In view of the enormous number of works on Marxism in general and in light of the many books and articles touching on the relationship of Marxism to religion in particular, it may fairly be asked why yet another such work should be produced. My reply is that in eliciting answers to the kinds of questions posed by the methodology I have used, it was necessary to go to the primary sources almost exclusively. This is not to bemoan a sad fate but to affirm that there are notable deficiencies in the secondary sources relevant to my topic. By way of general indictment, I contend that the major difficulty with existing studies of the Marxist critique of religion is that their authors, whether expositors or critics, have failed both to specify their own presuppositions concerning religion and to approach the subject with an adequate comprehension of its many dimensions. Since, in most cases, the reader is equally unprepared, anthropologically, sociologically, psychologically, and historically, for clear and informed thought in this vast and nebulous area, the result has been widespread confusion. As if this were not enough, numerous writers with little more than polemical interests have compounded the confusion by failing to distinguish between religion in general and their own brands of faith in particular. Others have not discriminated between the concepts of metaphysics and the supernatural items of religious belief. 188 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The systematic use of propaganda is very much a phenomenon of the 20th century. Through the years, kings, political leaders, and statesmen have often made use of what might now be called 'propaganda tech niques' but it is only within the present century that the use of pro paganda has been developed as a systematic instrument of national and foreign policy. Nonetheless, since World War II propaganda has become a regular peacetime instrument of foreign policy for most states, be they large or small. While some considerable attention has been given to the propaganda organisations and activities of the United States and certain Com munist nations, especially the U.S.S.R., relatively little has been done on the British approach to propaganda. The present study attempts to at least partially fill that vacuum. A history of the overseas Informa tion Services is not undertaken and I will leave that important task to future scholars. Instead I have examined the British approach to the organisation of propaganda and the mechanics they have developed to utilize this instrument of foreign policy. 132 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book is intended to provide an introductory text of Nonlinear and Dynamic Programming for students of managerial economics and operations research. The author also hopes that engineers, business executives, managers, and others responsible for planning of industrial operations may find it useful as a guide to the problems and methods treated, with a view to practical applications. The book may be considered as a sequel to the author's Linear Programming in Industry (1960, 4th revised and enlarged edition 1974), but it can be used independently by readers familiar with the elements of linear programming models and techniques. The two volumes con stitute an introduction to the methods of mathematical programming and their application to industrial optimization problems. The author feels that the vast and ever-increasing literature on mathematical programming has not rendered an introductory exposition super fluous. The general student often tends to feel somewhat lost if he goes straight to the special literature; he will be better equipped for tackling real problems and using computer systems if he has acquired some previous training in constructing small-scale programming models and applying standard algorithms for solving them by hand. The book is intended to provide this kind of training, keeping the mathematics at the necessary minimum. The text contains numerous exercises. The reader should work out these problems for himself and check with the answers given at the end of the book. The text is based on lectures given at the University of Copenhagen. 168 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -More than 150 years have passed since involvement of the nervous system in leukemia was first reported by BURNS, while the possibility of the primary brain tumor derived from the lymphoreticular tissue was recognized much later. BAILEY in 1929 described such neoplasms under the term perithelial sarcoma. Later these tumors of the nervous system have been variously designated as 'Perivascular of perithelial sarcomas, reticulum cell sarcomas or microgliomas', as controversy has evolved and still exists on the definition of this group of neoplasms and on the nature of their cells of origin. Much of the unfortunate confusion concerning the neoplastic lesions attributed to 'microglia' and other derivations of the RE system arose because their close relationship to extra neural cells has been ignored. On the other hand, communication in the field of malignant lymphomas has become increasingly difficult because of the termino logic maze and conceptual diversities of traditional morphological classifica tions that have limited valid comparisons. Although at present we are still far from a precise recognition of the basic features of lymphoproliferative processes and from a fairly general agreement on the terminology of non-Hodgkin lymphomas, there is encouraging evidence recently of some enlightment on the nature of tumor cells that provides the basis for a reasonable and generally acceptable lymphoma classification. 316 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This monograph is based, in part, upon lectures given in the Princeton School of Engineering and Applied Science. It presupposes mainly an elementary knowledge of linear algebra and of topology. In topology the limit is dimension two mainly in the latter chapters and questions of topological invariance are carefully avoided. From the technical viewpoint graphs is our only requirement. However, later, questions notably related to Kuratowski's classical theorem have demanded an easily provided treatment of 2-complexes and surfaces. January 1972 Solomon Lefschetz 4 INTRODUCTION The study of electrical networks rests upon preliminary theory of graphs. In the literature this theory has always been dealt with by special ad hoc methods. My purpose here is to show that actually this theory is nothing else than the first chapter of classical algebraic topology and may be very advantageously treated as such by the well known methods of that science. Part I of this volume covers the following ground: The first two chapters present, mainly in outline, the needed basic elements of linear algebra. In this part duality is dealt with somewhat more extensively. In Chapter III the merest elements of general topology are discussed. Graph theory proper is covered in Chapters IV and v, first structurally and then as algebra. Chapter VI discusses the applications to networks. In Chapters VII and VIII the elements of the theory of 2-dimensional complexes and surfaces are presented. 204 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The first edition of this book appeared in 1953; the second, revised and enlarged, in 1960. The present, third edition is essentially a reprint of the second, except for the correction of a few misprints and the following remarks, which refer to some recent publications\* and replace the brief preface to the second edition. Neither Eudemus nor Theophrastus, so I said (p. 208£. ) knew a branch of theoretical philosophy the object of which would be something called 0'. 1 ~ 0'. 1 andwhich branch wouldbedistinct from theology. And there is no sign that they found such a branch (corresponding to what was later called metaphysica generalis) in Aristotle. To the names of Eudemus and Theophrastus we now can add that of Nicholas of Damascus. In 1965 H. J. Drossaart Lulofs published: Nicolaus Damascenus On the Philosophy of Aristotle (Leiden: Brill), Le. fragments of his m:pr. njc; 'ApLO''t'o't'&AOUC; qJLAOO'OqJLiXC; preserved in Syriac together with an English trans lation. In these fragments we find a competent presentation of Aristotle's theoretical philosophy, in systematic form. Nicholas subdivides Aristotle's theoretical philosophy into theology, physics, and mathematics and seems to be completely unaware of any additional branch of philosophy the object of which would be 0'. 1 ~ 0'. 1 distinct from theology with its object (the divine). 276 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book is first of all designed as a text for the course usually called 'theory of functions of a real variable'. This course is at present cus tomarily offered as a first or second year graduate course in United States universities, although there are signs that this sort of analysis will soon penetrate upper division undergraduate curricula. We have included every topic that we think essential for the training of analysts, and we have also gone down a number of interesting bypaths. We hope too that the book will be useful as a reference for mature mathematicians and other scientific workers. Hence we have presented very general and complete versions of a number of important theorems and constructions. Since these sophisticated versions may be difficult for the beginner, we have given elementary avatars of all important theorems, with appro priate suggestions for skipping. We have given complete definitions, ex planations, and proofs throughout, so that the book should be usable for individual study as well as for a course text. Prerequisites for reading the book are the following. The reader is assumed to know elementary analysis as the subject is set forth, for example, in ToM M. APOSTOL's Mathematical Analysis [Addison-Wesley Publ. Co., Reading, Mass., 1957], orWALTERRUDIN's Principles of Mathe matical Analysis [2nd Ed., McGraw-Hill Book Co., New York, 1964]. 492 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -The term isoenzyme is used to describe enzymically active proteins, catalysing the same reaction and occurring in the same species, but differing in certain of their physico-chemical properties. Although the occurrence of enzymes in multiple molecular forms has been recognized for several decades, the application of electrophoretic and, to a lesser extent, chromatographic techniques has led to rapid developments in recent years. Since the discovery of the heterogeneity of lactate dehy drogenase, reported almost simultaneously by Vesel I and Beam and by Wieland and Pfleiderer in 1957, the multiple forms of this enzyme have become the subject of an extensive literature, and the techniques introduced have been applied to investigations of other isoenzymes. Isoenzymes, especially those of lactate dehydrogenase and alkaline phosphatase, have found many applications as diagnostic agents in clin ical chemistry, while others, such as those of cholinesterase and glucose 6-phosphate dehydrogenase, exhibit a biological polymorphism of con siderable interest in genetics. Recent additions to our understanding of the chemical structure of the lactate dehydrogenase isoenzymes have indicated their great potential in fields as diverse as immunology, em bryology and comparative anatomy. These remarkable developments suggest that the time is opportune for present knowledge to be surveyed, and I have compiled this monograph in the hope that it will be found useful by biochemists, pathologists, clinicians, geneticists and others with interests in enzymology. 384 pp. Englisch.
