Taschenbuch. Condizione: Neu. Neuware -Many historians have concerned themselves with the founding of the German Empire in 1871 and the means used to unite the disparate sections of Germany, many of which had older traditions than did Bismarck's Prussia. Understandably writers have given more attention to the victor than to the vanquished. Except for polemicists who seek to prove the wrong done or to vindicate the action taken, scholars have been interested in writing about trends which were to become significant in the new Reich, about the new governmental structure itself, and about the diplomacy and statesmanship which were used to form the new German nation-state. But the consolidation of many diverging strands of political, economic, and social traditions in the new state left many issues unsolved and in fact seemed to create new ones. Many of these problems, while not overtly affecting the basic outline of German history, have nonetheless influenced it and have become at times serious matters of concern for the Reich Chancellor. One of the problems was the threat of particularist sentiment to the national unity which Bismarck was trying to create. Although there was an awareness among some nineteenth century Ger mans of a specific German nationality, the majority of people did not think in terms of a German unity but regarded themselves as Bavarians, Saxons, or belonging to some other Stamm, or tribal subdivision of the Germans.…

Taschenbuch. Condizione: Neu. Neuware -The design and assessment of modern high temperature plant demands an understanding of the creep and rupture behaviour of materials under multi axial stress states. Examples include thread roots in steam turbine casing bolts, branch connections in nuclear pressure vessels and blade root fixings in gas or steam turbine rotors. At one extreme the simple notch weakening/notch strengthening characterization of the material by circumferentially vee-notched uniaxial rupture tests, as specified in many national standards, may be sufficient. These were originally intended to model thread roots and their conservatism is such that they frequently are considered adequate for design purposes. At the other extreme full size or model component tests may be employed to determine the safety margins built into design codes. This latter approach is most commonly used for internally pressurized components, particularly where welds are involved. However, such tests are extremely expensive and the use of modern stress analysis techniques combined with a detailed knowledge of multiaxial properties offers a more economic alternative. Design codes, by their nature, must ensure conservatism and are based on a material's minimum specified properties. In the case of high temperature components the extension of life beyond the nominal design figure, say from 100000 to 200000 h, offers very significant economic benefits. However, this may require a more detailed understanding of the multiaxial behaviour of a specific material than was available at the design stage.…

Taschenbuch. Condizione: Neu. Neuware -Technology transfer has a long history, but only recently has it become the subject of study and action. The rapid rate of scientific and technical advance in both Europe and the United States and the existence of large technology gaps among nations has brought the importance of the process into sharper focus, and has c~used technology transfer to have implications for countless aspects of both national and international develop ment. Technology transfer has been variously defined as: the process of information transfer between science, technology and actual utilization of scientific data and ideas, to wit: production of goods and services; the process by which science and technology are diffused throughout human activity; the transfer of research results into operations; the process by which technical information originating in one setting is adapted for use in another setting. Collectively, these and other definitions share a common theme which characterizes the process as one of bringing technology i'ilto widespread use in solving mankind's problems in the shortest practical time. The first NATO Advanced Study Institute (ASI) on Technology Transfer in July, 1973, brought together many of the individuals dealing with quantitative data, based on empirical research. This conference had both the advantages and disadvantages of a somewhat detached point of view. The ASI also had lectures contributed by representatives from government agencies and corporations (and a few university-based scholars) who had been active as practitioners or consultants in policy-making and organizational design for technology transfer.…

Motivation This book is based on the view-tx)int that both public and private decision making, in practice, can often be ilrproved upon by means of fonnal (nonnative) decision nodels and methods. To sane extent, the validity of this statement can be measured by the irrpressive number of su=esses of disciplines as operations research and management science. Hcwever, as witnessed by the many discussions in the professional journals in these fields, many rrodels and methods do not completely meet the requirements of decision making in prac tice. Of all possible origins of these clear shortcomings, we main- ly focus on only one: the fact that nost of these nodels and methods are unsuitable for decision situations in which multiple and possi bly conflicting objectives playa role, because they are concentra ted on the (optimal) fulfilment of only one objective. The need to account for multiple goals was observed relatively early. Hoffman [1955], while describing 'what seem to be the prin cipal areas (in linear prograrrrning) where new ideas and new methods are needed' gives an exanple with conflicting goals. In this pro blem, the assignrrent of relative weights is a great problem for the planning staff and is 'probably not the province of the mathemati cian engaged in solving this problem'. These remarks were true pre cursors of later develor:nents. Nevertheless, the need for methods dealing with multiple goals was not widely recognized until much later. 276 pp. Englisch. …

This item is printed on demand - it takes 3-4 days longer - Neuware -Until the nineteenth century Jacques-Auguste de Thou (1553-1617) was among the most famous and most valued of historians. While his first fame was a succes de scandale - the History of His Time was placed on the Index in 160g - de Thou's work quickly found favor with the humanistically-educated learned class throughout Europe. The esteem in which the History was held transcended religious divisions. The historian received letters of praise from staunchly orthodox Spain and Portugal as well as from heretic England and Germany; through the seventeenth and eighteenth centuries his History was read with enthusi asm by certain cardinals at the very curia which condemned it; and so staunch a champion of orthodoxy as Bishop Bossuet did not hesitate to appeal to 'such a great author' for support in his own historical works. ! To the philosophe of the Enlightenment de Thou's impartiality in de scribing the impassioned times through which he lived and the exact yet eloquent style with which he wrote the History of His Time were familiar touchstones. Voltaire appealed to the 'truthful and eloquent de Thou' again and again in his works,2 William Pitt rose in the House of Commons to quote the words of the 'great historian of France' during the early years of the French Revolution,3 Lessing 4 and Herder 5 praised him with poetic hyperbole, and Edward Gibbon re ferred to 'the authority of my masters, the grave Thuanus and the philosophic Hume . . . . 368 pp. Englisch.…

This item is printed on demand - it takes 3-4 days longer - Neuware -When in 1925 the initiative was taken by the Kern Institute Leiden to start the publica tion of an Annual Bibliography of Indian Archaeology, the Board of the Institute could do so with confidence, as it was sure of the assistance of scholars all over the world as to the supply of publications as well as of information. With the help of this material a bibliography could be compiled by a small team of highly skilled archaeologists who could devote part of their time and attention to such a task for the benefit of their colleagues in all parts of the world. Times since then have changed, and circumstances have become less and less favourable. To find classified labour for the compilation and editing of such a bibliography has become extremely difficult, and this the more so as this work cannot be paid in accordance with the standards for this branch of classified documentation. The work has to be done as a part of the daily routine work even a scholar in today's time is expected to perform, and which he cannot but consider as being detrimental to the performing of those parts of his work, that demand the use of those qualifications that actually make him the expert. 192 pp. Englisch.…

Present problems are aggravated by aging and neglected facilities, by inadequate financing and by water management institutions reflecting the needs of an earlier era. Service needs to be provided for expanding populations, at the same time that corrective measures must be taken for decaying older urban centers, resulting both from neglect and expiring service life. These needs exist within the framewode of other competing and conflicting uses for existing and yet to be developed water sources. The problems have generated some highly visible national debates over financing due to the large sums involved. Despite differences in the age of the North American, European and other societies, the technological ages of water supply and storm water systems are much the same and provide a common denominator in the worldwide trend to urbanization. Examination of approaches to urban water management also indicates that they are generally based on past experience and institutions created in a non-urban era. The physical, financial and institutional alternatives are consequently often out-of-step with current urban environment. Historically, the supply of adequate water and efficient storm water management have also been top priority items with water quality and other aspects of environmental protection assuming a lower priority after basic supply needs have been met. 320 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The history of modern helioseismology is only ten years old. In 1975 F-L Deubner separated for the first time the spatial and temporal pro perties of the solar five-minute oscillations, and was thus able to measure the dispersion relation for high-degree acoustic modes (p modes). The diagnostic value of these observations was appreciated immediately. Indeed, by comparing the observed relation with computations that had already been carried out by R.K. Ulrich, and subsequently by H. Ando and Y. Osaki, it was recognised that contemporary solar models that had been constructed with the low observed neutrino flux in mind were too hot in their outer layers. Moreover, their convection zones were too shallow. Since that time the observations have improved. There is now good reason to suppose that a sufficiently careful analysis will lead to a direct determination of the helium abundance in the solar convection zone, especially when foreseeable further improvements in the observations have been achieved. The data will also provide useful diagnostics of the uncertain equation of state of partially ionized plasmas, and they might also enable us to measure the large-scale structure of the convec tive flow. 496 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book is intended to be a reference text on hydrostatic extru sion, a multidisciplinary technology involving the forming process of materials, tribology, high pressure engineering and so forth. Until now only one book bearing the title of hydrostatic extrusion, by Prof. Alexander and Dr. Lengyel, has been published since 1971. Although there are chapters on hydrostatic extrusion in such books as THE MECHANICAL BEHAVIOUR OF MATERIALS UNDER PRESSURE edited by Dr. Pugh, METAL FORMING by Prof. Avitzur and HIGH PRESSURE TECHNOLOGY by Drs. Spain and Paauwe, it is regrettable that no up~to-date reference books on hydro static extrusion are available. As is well known, hydrostatic extrusion is a nearly-ideal lubricated extrusion. Its advantages have been demonstrated by laboratory research in the past two decades, yet many manufacturers, however, still hesitate to adopt the technology in their plants. Their hesitation is certainly due to the lack of exact information on the process and its equipment and also to 'their unfamiliarity with the actual method of operation. In order to provide a useful introduction to the subject for engi neers who work in industries which plan to employ this technique and also to give exact and reliable information on the durability and perfo- ance of production facilities, as well as the capabilities of the process and the properties of extruded products, we decided to publish this book. Starting with theories and computational methods, the processes of cold, warm and hot hydrostatic extrusion are described by experts in their respective fields. 396 pp. Englisch. …

The Scandal of Father 'The Hermit Clad in Crane Feathers' in R. Brown 'The point of a Pin'. van Gulik's The Chinese Maze Murders. Growing specialization and diversification have brought a host of monographs and textbooks on increasingly specialized topics. However, the 'tree' of knowledge of mathematics and related fields does not grow only by putting forth new branches. It also happens, quite often in fact, that branches which were thought to be completely disparate are suddenly seen to be related. Further, the kind and level of sophistication of mathematics applied in various sciences has changed drastically in recent years: measure theory is used (non-trivially) in regional and theoretical economics; algebraic geometry interacts with physics; the Minkowsky lemma, coding theory and the structure of water meet one another in packing and covering theory; quantum fields, crystal defects and mathematical programming profit from homotopy theory; Lie algebras are relevant to filtering; and prediction and electrical engineering can use Stein spaces. And in addition to this there are such new emerging subdisciplines as 'experimental mathematics', 'CFD', 'completely integrable systems', 'chaos, synergetics and large-scale order', which are almost impossible to fit into the existing classification schemes. They draw upon widely different sections of mathematics. 492 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The photosynthetic process of higher plants converts carbon dioxide, water, and, light quanta into reduced sugars. The enzymes which catalyze this conversion are contained within the chloroplasts and can be thought of as split into two distinct groups. In one group are the enzymes of the IIlightll reactions, which harvest the light, oxidize water and generate two energy-rich intermediates, ATP and NADPH. These two intermediates plus carbon dioxide are the substrates for the second group, the IIdarkll reactions or Cal vi n cycle, which produce the reduced sugars. The chloroplast is completely bounded by an outer membrane. There is a separate, highly convoluted membrane system, the thyla koid system, enclosed within the chloroplast. The enzymes of the light reactions are physically associated with the thylakoid mem branes, while the Calvin cycle enzymes are free-floating within the stroma, or soluble part of the chloroplast (Fig. 1).

Leo Blitz (now at the University of Maryland) and I decided that there was a need, and agreed that we would organize one in Vancouver in the Spring of 1982. The purpose of the workshop was to have an intensive exchange of ideas between some of the most active workers in the field regarding the recent work which has been significantly changing our concepts of the Milky Way. To achieve this we limited the number of participants, and planned the program so that there was ample time for discussion. The meeting appeared to work very well, both scientifically and socially, and this volume contains 50 of the 55 papers that were The discussion was very lengthy, but since the papers were presented. written up after the meeting many of the points raised have been in the publications, and it seems pointless to reproduce it incorporated here.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In the last ten years, the chemistry and physics of materials with layered structures became an intensively investigated field in the study of the solid state. Research into physical properties of these crystals and especially investigations of their physical anisotropy related to the structural anisotropy has led to remarkable and perplexing results. Most of the layered materials exist in several polytypic modifications and can include stacking faults. The crystal structures are therefore complex and it became apparent that there was a great need for a review of the crystallographic data of materials approximating two-dimensional solids. This second volume in the series 'Physics and Chemistry of Materials with Layered Structures' has been written by specialists of different classes of layered materials. Structural data are reviewed and the most important relations between the structure and the chemical and physical properties are emphasized. The first three contributions are devoted to the transition metal dichalcogenides whose physical properties have been investigated in detail. The crystallographic data and crystal growth conditions are presented in the first paper. The second paper constitutes an incisive review of the phase transformations and charge density waves which have been observed in the metallic dichalcogenides. In two contributions the layered structures of newer ternary compounds are de scribed and the connection between structure and non-stoichiometry is discussed. 384 pp. Englisch.…

The dedication of the meeting to Alexander von Humboldt presented partici pants with the challenge that the discussions during the week should reflect the spirit of that great scientist of the last century, that the very many interesting ideas presented and developed during the sessions should be interpreted in the light of a broad v~ew of astron omy and astrophysics. The topics of the meeting ranged from astrometric questions relating to the specification of inertial reference systems, motion of planets (including minor planets) and satellites, with the recurring topic of the search for criteria of stability of the systems, resonances, periodic orbits, and to the origin of the systems. Each session began with one or more invited review papers, followed by offered contributions and discussion. Three evening discussions were held, devoted respectively to inertial systems, to numerical integration techniques, and to cosmogonic problems and ring systems.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The production of rice has increased considerably in recent years due to the release of improved varieties and the adoption of better fertilization practices. Nevertheless, the production and use of inorganic N fertilizer involves costly investments in terms of energy and transport, the need for complex manufacturing plants, as well as the potential for environmental pollution. The use of agricultural systems that include dinitrogen fixing organisms appears to be an economically sound cultural practice. In the particular case of rice, biological nitrogen fixation by Azolla, blue-green algae (BGA), and heterotrophic microorganisms has long been recognized, in southeast Asia, as a fertilizer for rice culture. The Azolla-Anabaena association has the unique property of being able to retain a significant amount of nitrogenase activity in the presence of combined nitrogen, making the system compatible with inorganic nitrogen fertilization. Researchers working with Azolla (N fixation) are dispersed in 2 countries of southeast Asia, Africa, Europe and Latin America, making it difficult to share ideas, concepts and research results on a more personal basis. Considering the potential positive impact of growing rice in association with Azolla, and the lack, to date, of an international gathering of scientists dedicated to Azolla research, the First International Workshop on 'Practical Applications of Azolla for Rice Production' was organized by the University of Puerto Rico-Mayaguez Campus. 240 pp. Englisch.…

This item is printed on demand - it takes 3-4 days longer - Neuware -These proceedings are based upon introductory talks, research reports and discussions from the NATO Advanced Workshop on the 'Morphology and Dynamics of the Polar Cusp', held at Lillehammer, Norway, 7-12 May, 1984. The upper atmosphere at high latitudes is called the 'Earth's win dow to outer space'. Through various electrodynamic coupling process es as well as through direct transfer of particles many geophysical effects displayed there are direct manifestations of phenomena occurring in the deep space. The high latitude ionosphere will also exert a feedback on the regions of the magnetosphere and atmosphere to which it is coupled, acting as a momentum and energy source and sink, and a source of particles. Of particular interest are the sections of the near space known as the Polar Cusp. A vast portion of the earth's magnetic field envelope is electrically connected to these regions. This geometry results in a spatial mapping of the magnetospheric pro cesses and a focusing on to the ionosphere. In the Polar Cusps the solar wind plasma has also direct access to the upper atmosphere. The polar regions are thus of extreme importance when it comes to under standing the physical processes in the near space and their effect on our environment. The Introductory Talks given at this workshop provided a common background for discussing and understanding the physics of the Polar Cusp. By this book we will make the information which thus was provid ed to the participants of the workshop accessible to a wider audience. 444 pp. Englisch. …

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The geometrical theory of nonlinear differential equations originates from classical works by S. Lie and A. Bäcklund. It obtained a new impulse in the sixties when the complete integrability of the Korteweg-de Vries equation was found and it became clear that some basic and quite general geometrical and algebraic structures govern this property of integrability. Nowadays the geometrical and algebraic approach to partial differential equations constitutes a special branch of modern mathematics. In 1993, a workshop on algebra and geometry of differential equations took place at the University of Twente (The Netherlands), where the state-of-the-art of the main problems was fixed. This book contains a collection of invited lectures presented at this workshop. The material presented is of interest to those who work in pure and applied mathematics and especially in mathematical physics. 356 pp. Englisch.…

This item is printed on demand - it takes 3-4 days longer - Neuware -This book comprises the essential records from a Boerhaave course given in June 1971 for specialists in cardiology and other fields of internal medicine interested in the subject of quantitation in cardiology. It is evident that in the wide field of medicine, and particularly in cardiology, there is a growing need for exact and detailed information in conjunction with existing diag nostic methods. This is apparent in the greater precision in anatomical and haemodynamic details required by the thoracic surgeon as the number of available heart operations gradually increases. In retrospect it is hardly surprising that the high initial mortality after the introduction of each operation depended to a large extent upon the degree of accuracy with which the diagnosis was made. Another urgent need for precise and quantitative information became apparent when monitoring of high-risk patients, in order to forestall compli cations and/or death, became routine. The same applies for the diagnostic procedures used to estimate the patient's chances of surviving an operation and/or rehabilitation after a serious incident, such as myocardial infarction. In these fields there is a vast amount of data to be handled and - in modern diagnostic procedures - it must be processed so rapidly that the human mind cannot suffice and computer equipment has becomeindispensable. 256 pp. Englisch.…

Elliot, V. L. Ginzburg, B. Peters, Y. Sekido, and J. A. Simpson met together as a dinner party devoted to the enjoyment of Japanese cuisine and reminiscences of our younger days. This pleasant occasion called to of our own age as well as some eminent seniors not present at the mind the many friends conference whose recollections would have further enriched and enlivened our evening. By the time the dinner came to an end we had agreed that the compilation of a more extensive collection of personal reminiscences would be an interesting and worthwhile undertaking. Accordingly, the next day we held an editorial meeting to draw up a list of potential authors and two of us, the present editors, started work on the project. In putting the book together our intention has been to try to capture and record through these personal accounts something of the atmosphere, the excitement and the frustrations of research in cosmic rays as experienced at first hand by some of the practi tioners in the field. It has never been our intention that it should comprise a systematic history of the subject. Neither, unfortunately, can it be a fully representative collection since practical limits to the size of the volume alone would preclude that. 464 pp. Englisch. …

While primary emphasis will be placed upon theoretical, conceptual, and epistemological aspects of these problems and domains, empirical, experimental, and methodological studies will also ap pear from time to time. The present volume provides a collection of studies that focus on some of the central problems within the domain of artificial intelligence. These difficulties fall into four principal areas: defeasible reasoning (including the frame problem as apart), ordinary language (and the representation prob lems that it generates), the revision of beliefs (and its rules of inference), and knowledge representation (and the logical problems that are encountered there). These papers make original contributions to each of these areas of inquiry and should be of special interest to those who understand the crucial role that is played by questions of logical form. They vividly illustrate the benefits that can emerge from collaborative efforts involving scholars from linguistics, philosophy, computer science, and AI. J. H. F. 452 pp. Englisch. …

In the year 1988, the University of Bologna celebrated its 900th Anniversary. ZIRCONIA '88 was one of the celebration events which brought together academics and researchers from allover the world. Under the chairmanship of Prof. C. Palmonari, Director of the Italian Ceramic Center of the University of Bologna, the Organizing Committee consisting of J. Castaing (C.N.R.S. Meudon, France), S. Meriani (University of Trieste, Italy), V. Prodi (Un-iversity of Bologna, Italy) and J. Routbort (U.S. Dept. of Energy, Washington, USA) conducted a conference program of 47 contributions presented to the 220 enrolled Zirconia participants, out of the 775 enlisted within the main SIMCER framework. The aim of ZIRCONIA '88 was to follow the stream of the well known International Conferences on the Science and Technology of zj rconia held in Cleveland, Ohio (1980), Stuttgart, Federal Republic of Germany (1983) and Tokyo, Japan (1986). SIMCER's goal was to bring together not only scientists and engineers directly involved with 'advanced' ceramics but also a larger audience connected to the nearby Italian Ceramic District of Sassuolo. 396 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -It has not been my intention to write a definitive study of appeasement. Such a work would have to include the French variety, Stalin's appeasement of Hitler between 1939 and 1941, or the appeasement of Japan in 1938 and 1939. I chose the British case for a number of reasons. The opportunity of a comparative model was a challenge, British appeasement was well known, and the structure of the British government remained rather the same in the intervening period between Waterloo and Dunkirk. I admit that Amiens and Munich represent the most dramatic episodes in the story of appeasement, but then the British struggles against Bonaparte and Hitler were of epic proportions. It was of course unnecessary 'to prove' appeasement at Munich, but very few historians had looked at the treaty of Amiens in this way. Much of my research effort was therefore devoted to examining the published material of the earlier period. While I have used some original Addington documents, this work is not primarily an inquiry into unpublished sources but a rein terpretation of well known events that were made public long ago. The flood of publications and revelations of the 1930's continues unabated. I have tried to use the latest studies, especially those that have benefited from the thirty year rule. My debts of gratitude extend over a long period since two stints as chairman of the department have delayed this book by at least four years. 168 pp. Englisch.…

This item is printed on demand - it takes 3-4 days longer - Neuware -The food technologist who wishes to produce a gelled product is faced with two basic options for achieving the desired effect; whether to use a protein or a polysaccharide. Although a gel can be formed by either a protein or a polysaccharide, the resultant gels have different characteristics: - Polysaccharide gels are characterised by their fine texture and transparency which is achieved at a low polymer concentration. They can be formed by heating and cooling, pH adjustment or specific ion addition . - Protein gels are characterised by a higher polymer concentration (5-10%) and are formed almost exclusively by heat denaturation. Before reaching a final decision, the technologist must take a number of factors into consideration. The purpose of this book is to help the technologist in his choice by providing fundamental practical information, in one book, on the properties of gels (and factors which influence them) for both types of biopolymer. To help the reader, each chapter is (wherever possible) organised in the same way so that, for example, information on structure will always be available in section 2. The examples in the Applications section of each chapter are not meant to be exhaustive, but to illustrate the various ways in which the particular polymer can be used to form a gelled product. 492 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -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. 636 pp. Englisch.…

This item is printed on demand - it takes 3-4 days longer - Neuware -The present work constitutes an effort to approach the subject of symbol ic logic at the elementary to intermediate level in a novel way. The book is a study of a number of systems, their methods, their rela tions, their differences. In pursuit of this goal, a chapter explaining basic concepts of modern logic together with the truth-table techniques of definition and proof is first set out. In Chapter 2 a kind of ur-Iogic is built up and deductions are made on the basis of its axioms and rules. This axiom system, resembling a propositional system of Hilbert and Ber nays, is called P +, since it is a positive logic, i. e. , a logic devoid of nega tion. This system serves as a basis upon which a variety of further sys tems are constructed, including, among others, a full classical proposi tional calculus, an intuitionistic system, a minimum propositional calcu lus, a system equivalent to that of F. B. Fitch (Chapters 3 and 6). These are developed as axiomatic systems. By means of adding independent axioms to the basic system P +, the notions of independence both for primitive functors and for axiom sets are discussed, the axiom sets for a number of such systems, e. g. , Frege's propositional calculus, being shown to be non-independent. Equivalence and non-equivalence of systems are discussed in the same context. The deduction theorem is proved in Chapter 3 for all the axiomatic propositional calculi in the book. 372 pp. Englisch. …
