Buch. Condizione: Neu. Neuware - There is a great deal of interest in the general subject of porous inorganic materials in regard to their use as sorbents or catalysts. The solids may be microporous, mesoporous, or macroporous. Often there is a range of pore sizes within any given solid, and so there is special interest in the synthesis, characterisation and application of solids having well-defined pores. The first part of the book deals with the theory and practice of the measurement of pore-size distributions. Part II goes into porous crystalline materials. The zeolites are, by definition, microporous, but it is important to understand the mechanisms whereby such crystalline porous materials are formed, so as to suggest methods for the synthesis of mesoporous materials. Pillared layered solids are investigated in Part III. There are clear indications that the current generation of microporous materials may be developed to give PLS which combine micro and mesoporosity, while a totally mesoporous solid may not be far off. part IV covers sol-gel methods, where important new developments mean that oxides can be produced with high purity and with well-defined pore sizes. Methods of characterising the materials are also studied, with solid state NMR (including 27Al-NMR), X-ray and neutron scattering, pulsed ESR, and electrokinetic potential measurements being discussed in Part V. Finally, applications are discussed in Part VI.

This item is printed on demand - it takes 3-4 days longer - Neuware -The work collected in this book represents the results of some intensive recent work on the syntax of natural languages. The authors' differing viewpoints have in common the program of revising current conceptions of syntactic representation so that the role of transformational derivations is reduced or eliminated. The fact that the papers cross-refer to each other a good deal, and that authors assuming quite different fram{:works are aware of each other's results and address themselves to shared problems, is partly the result of a conference on the nature of syntactic representation that was held at Brown University in May 1979 with the express purpose of bringing together different lines of research in syntax. The papers in this volume mostly arise out of work that was presented in preliminary form at that conference, though much rewriting and further research has been done in the interim period. Two papers are included because although they were not given even in preliminary form at the conference, it has become clear since then that they interrelate with the work of the conference so much that they cannot reasonably be left out: Gerald Gazdar's statement of his program for phrase structure description of natural language forms the theoretical basis that is assumed by Maling and Zaenen and by Sag, and David Dowty's paper represents a bridge between the relational grammar exemplified here in the papers by Perlmutter and Postal on the one hand and the Montague 504 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Iterative methods for calculating static fields are presented in this book. Static field boundary value problems are reduced to the boundary integral equations and these equations are solved by means of iterative processes. This is done for interior and exterior problems and for var ious boundary conditions. Most problems treated are three-dimensional, because for two-dimensional problems the specific and often powerful tool of conformal mapping is available. The iterative methods have some ad vantages over grid methods and, to a certain extent, variational methods: (1) they give analytic approximate formulas for the field and for some functionals of the field of practical importance (such as capacitance and polarizability tensor), (2) the formulas for the functionals can be used in a computer program for calculating these functionals for bodies of arbitrary shape, (3) iterative methods are convenient for computers. From a practical point of view the above methods reduce to the cal culation of multiple integrals. Of special interest is the case of inte grands with weak singularities. Some of the central results of the book are some analytic approximate formulas for scattering matrices for small bodies of arbitrary shape. These formulas answer many practical questions such as how does the scattering depend on the shape of the body or on the boundary conditions, how does one calculate the effective field in a medium consisting of many small particles, and many other questions. 140 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book is about metamorphic rocks: the processes involved in their formation and the reasons why they occur at particular places on the continents. It has been written to serve as an elementary text on the subjects of metamorphism and mountain building for non-specialist stu dents of geology. It will be equally useful where geology is either the main or subsidiary subject and could be used by students intending to advance further in geology (the list of advanced texts in the further reading section would be more appropriate to such students). My inten tion in writing this book has been to try to dispel the notion that metamorphism comprises the 'haunted wing' of geology. Admittedly, there are rather a large number of technical terms in the book, but I hope that after working through it you will not find metamorphism an unduly difficult or obscure aspect of geology. Throughout, I have emphasised the strong links between mountain building, plate tectonics and metamorphic processes. The book introduces metamorphic rocks by considering their textures and field relations, then moves on to deal with the factors controlling metamorphism. Case studies of areas of metamorphic rocks are then presented in the context of modern theories of the Earth's activity, and the place of metamorphic rocks in the formation of ancient and young mountain belts is analysed. New technical terms and concepts are explained in context as they are introduced, important terms being emphasised in bold print. 164 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -The advances in the field of anaesthesiology and reanimation have contributed in all developed countries to the decrease in deaths occurring on the operating table (exitus in tabula), from the ratio 1: 100 (in the nineteenth century) down to approximately 1: 1000 (in the first half of the twentieth century) and finally to approxi mately 1: 10 000 (nowadays). Numerous human lives were saved not only through the intro duction of new medicine and methods but even more so by better training for the doctors and nurses who apply these new techni ques. I am happy about the splendid initiative of my student and friend Georg Kamm, which has now made these advances acces sible to the developing countries. He knows very well how to make his colleagues understand the theory and the practical side of modern anaesthesiology, under the most difficult conditions and in a completely different world, to such an extent that to day in his country all of his patients are given the benefit of the advances of medicine. There is nothing more rewarding for an academic teacher than to see how his students continue developing his ideas and spread them far and wide. I am therefore happy and proud to write this foreword for Georg Kamm, one of the pioneers of anaesthesiology in Africa. 176 pp. Englisch.

Huckel NO computations were rapidly succeeded by semiempirical monodeterminantal Self Consistent Field (SCF) MO calculations which now give way to high quality ab initio calculations of the poly-determinantal SCF-MO and Generalized VB variety. By contrast. no analogous progress has been made in the area of the qualitative theo~ of chemical bonding. In fact. more than a half-centu~ after the exposition of HUckel MO theory the conceptual superstructure of chemist~ is still founded on it. This is made glaringly evident by the fact that highly sophisticated computations are still interpreted with primitive HUckel MO theory. despite the fact that most chemists are well aware of its formal deficiencies. The current popularity Qf qual1tati. ve MO theory among experimental i sts is not the resul t ~f fonnai -advances ~Wt, rather the consequence of stimulating application of old MO theoreti~a. 1 ~oncepts. : . .

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The guiding principle in this book is to use differential forms as an aid in exploring some of the less digestible aspects of algebraic topology. Accord ingly, we move primarily in the realm of smooth manifolds and use the de Rham theory as a prototype of all of cohomology. For applications to homotopy theory we also discuss by way of analogy cohomology with arbitrary coefficients. Although we have in mind an audience with prior exposure to algebraic or differential topology, for the most part a good knowledge of linear algebra, advanced calculus, and point-set topology should suffice. Some acquaintance with manifolds, simplicial complexes, singular homology and cohomology, and homotopy groups is helpful, but not really necessary. Within the text itself we have stated with care the more advanced results that are needed, so that a mathematically mature reader who accepts these background materials on faith should be able to read the entire book with the minimal prerequisites. There aremore materials here than can be reasonably covered in a one-semester course. Certain sections may be omitted at first reading with out loss of continuity. We have indicated these in the schematic diagram that follows. This book is not intended to be foundational; rather, it is only meant to open some of the doors to the formidable edifice of modern algebraic topology. We offer it in the hope that such an informal account of the subject at a semi-introductory level fills a gap in the literature. 352 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This textbook, written by a dedicated and successful pedagogue who developed the present undergraduate algebra course at Moscow State University, differs in several respects from other algebra textbooks available in English. The book reflects the Soviet approach to teaching mathematics with its emphasis on applications and problem-solving -- note that the mathematics department in Moscow is called the I~echanics-Mathematics' Faculty. In the first place, Kostrikin's textbook motivates many of the algebraic concepts by practical examples, for instance, the heated plate problem used to introduce linear equations in Chapter 1. In the second place, there are a large number of exercises, so that the student can convert a vague passive understanding to active mastery of the new ideas. Thes~ problems are intended to be challenging but doable by the student; the harder ones have hints at the back of the book. This feature also makes the book ideally suited for learning algebra on one's own outside of the framework of an organized course. In the third place, the author treats material which is usually not part of an elementary course but which is fundamental in applications. Thus, Part II includes an introduction to the classical groups and to representation theory. With many American colleges now trying to bring their undergraduate mathematics curriculum closer to applications, it seems worthwhile to translate Soviet textbooks which reflect their greater experience in this area of mathematical pedagogy. 592 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The origin, dispersal, deposition and burial of natural sediment grains is the central concern of sedimentology. The subject is truly inter disciplinary, commands the attention of Earth scientists, is of consider able interest to fluid dynamicists and civil engineers, and it finds widespread practical applications in industry. Sedimentology may be approached from two viewpoints: a descrip tive approach, as exemplified by traditional petrography and facies analysis, and a quantitative approach through the physical and chemical sciences. Both approaches are complementary and must be used in tandem if the recent remarkable progress in the field is to be sustained. This text aims to introduce such a combined approach to senior undergraduate students, graduate students and to interested professional Earth scientists. Thus the many descriptive diagrams in the text are counterbalanced by the use of basic physical and chemical reasoning through equations. I have tried to construct a text that follows logically on from the origin of sediment grains through fluid flow, transport, deposition and diagenesis (the change from sediment to rock). The text has been written assuming that some basic previous instruction has been given in the Earth sciences and in general physics and chemistry. Certain important derivations are given in appendices. I have avoided advanced mathematical treatment since it is my opinion that recogni tion of the basic physical or chemical basis to a problem is more important to the student than the formal mathematical reduction of poorly gathered data.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Peter C. Ordeshook and Kenneth A. Shepsle If the inaugural date of modern economics is set at 1776 with the publication of Adam Smith's The Wealth of Nations, then the analytical tradition in the study of politics is not even a decade younger, commencing nine years later with the publication of the Marquis de Condorcet's Essai sur l'application de l'analyse iz la probabilite des decisions rendues iz la pluralite des voix. The parallel, however, stops there for, unlike Smith and other classical economists who laid an intel lectual foundation upon which a century of cumulative scientific research pro ceeded, analytical political science suffered fits and starts. Condorcet, himself, acknowledges the earlier work (predating the Essai by some fourteen years) of Borda and, from time to time during the nineteenth century, their contributions were rediscovered by Dodgson, Nanson, and other political philosophers and arithmeticians. But, by century's end, there was nothing in political science to compare to the grand edifice of general equilibrium theory in neoclassical eco nomics. Despite roots traversing two centuries, then, the analytical study of poli tics is a twentieth-century affair. The initial inspiration and insight of Condorcet was seized upon just after World War II by Duncan Black, who wrote several papers on the equilibrium properties of majority rule in specific contexts (Black, 1948a,b). He expanded upon these themes in his now deservedly famous monograph, The Theory of xi PREFACE xii Committees and Elections, and the lesser-known essay with R. A. 228 pp. Englisch.
