Buch. Condizione: Neu. Neuware -What is a number What is infinity What is continuity What is order Answers to these fundamental questions obtained by late nineteenth-century mathematicians such as Dedekind and Cantor gave birth to set theory. This textbook presents classical set theory in an intuitive but concrete manner.To allow flexibility of topic selection in courses, the book is organized into four relatively independent parts with distinct mathematical flavors. Part I begins with the Dedekind-Peano axioms and ends with the construction of the real numbers. The core Cantor-Dedekind theory of cardinals, orders, and ordinals appears in Part II. Part III focuses on the real continuum. Finally, foundational issues and formal axioms are introduced in Part IV. Each part ends with a postscript chapter discussing topics beyond the scope of the main text, ranging from philosophical remarks to glimpses into landmark results of modern set theory such as the resolution of Lusin's problems on projective sets using determinacy of infinite games and large cardinals.Separating the metamathematical issues into an optional fourth part at the end makes this textbook suitable for students interested in any field of mathematics, not just for those planning to specialize in logic or foundations. There is enough material in the text for a year-long course at the upper-undergraduate level. For shorter one-semester or one-quarter courses, a variety of arrangements of topics are possible. The book will be a useful resource for both experts working in a relevant or adjacent area and beginners wanting to learn set theory via self-study.…

Taschenbuch. Condizione: Neu. Neuware - Metal Carcinogenesis Testing explains fundamental principles of metal carcinogenesis as they are currently understood, and provides detailed practical descriptions of rapid and inexpensive in vitro assay methodology presently in use for the detection of potentially carci nogenic metals and their compounds. Mounting experimental evidence has suggested that a number of metals and their compounds are potentially carcinogenic to humans. Since humans are exposed to these potentially carcinogenic metals in industrial situations and through environmental pollution, it is essential that experimental protocols be available to identify the specific metal compounds that are potentially carcinogenic. This book affords a thorough description of the various carcinogenesis test systems available for metals, centering on those that are rapid, inexpensive, and most reliable. The principles are discussed at the level of human exposure, of animal studies, and of research in vitro. Additionally, the molecular mechanisms of metal-induced cancer are considered at each ofthese three levels.In large part, the emphasis rests on the use of in vitro, biochemical and bacterial studies, including tissue culture, because these methods are the basis of the rapid and inexpensive screening of potentially carcinogenic substances.…

All the topics treated hefe are eluci dated in terms of concrete examples, which have been chosen, for the most part, from the Held of analysis of the mechanical properties of steel, wood, and other materials. A necessary prerequisite for any study of correlation equations is so me knowledge of the moments of random variables. In the Appendix, there is provided a brief treatment of moments, as well as a discussion of the simplest methods of computing them. We have paid particular attention in this book to the techniques of computing correlation equations, and to the use of tables for alleviating the computationalload. The mathematical bases of the methods used in setting up correlation equations are expounded in the books cited at the end of this volume. A. M.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Two-fluid dynamics is a challenging subject rich in physics and prac tical applications. Many of the most interesting problems are tied to the loss of stability which is realized in preferential positioning and shaping of the interface, so that interfacial stability is a major player in this drama. Typically, solutions of equations governing the dynamics of two fluids are not uniquely determined by the boundary data and different configurations of flow are compatible with the same data. This is one reason why stability studies are important; we need to know which of the possible solutions are stable to predict what might be observed. When we started our studies in the early 1980's, it was not at all evident that stability theory could actu ally work in the hostile environment of pervasive nonuniqueness. We were pleasantly surprised, even astounded, by the extent to which it does work. There are many simple solutions, called basic flows, which are never stable, but we may always compute growth rates and determine the wavelength and frequency of the unstable mode which grows the fastest. This proce dure appears to work well even in deeply nonlinear regimes where linear theory is not strictly valid, just as Lord Rayleigh showed long ago in his calculation of the size of drops resulting from capillary-induced pinch-off of an inviscid jet. 484 pp. Englisch.…

An attempt is made to survey this field, but primary consideration is given tothreeprob lems under investigation in the Polymer Structure Labaratory of the Institue of High-Molecular Compounds, Academy of Seiences ofthe USSR. The first problern is the genetic coding of the biologically fun.ctional structure of proteins. Its solution is based on physical theories of hydrophobic interactions. The second problern is the conformational properties of pro teins as the factor governing enzyme activity. The most direct methods for experimental investigation of questions in this area are optical, principally those involving natural and magnetic rota tion of the plane of polarization. A substantial portion of the book concerns optical activity; the Faraday effect is discussed in an appendix. The third problern is the manifestation of the cooperative properties of enzymes in the kinetics of enzymatic reactions and the solution of complex kinetic problems. This problern is espe cially pressing in connection with research on allosteric enzymes, which are responsible for feedback in metabolic processes. An appendix describes a new method for solving kinetic problems, based on the theory of graphs. This volume extends and details certain of the ideas ex pressed in my previous book, Molecules and Life: An Introduction to Molecular Biophysics, which was published in this series in 1965. 208 pp. Englisch.…

DoETSCH in 1927 it has been known that the Laplace transform procedure is a reliable sub stitute for HEAVISIDE's operational calculus\*. However, the Laplace transform procedure is unsatisfactory from several viewpoints (some of these will be mentioned in this preface); the most obvious defect: the procedure cannot be applied to functions of rapid growth (such as the 2 function tr-+-exp(t)). In 1949 JAN MIKUSINSKI indicated how the un necessary restrictions required by the Laplace transform can be avoided by a direct approach, thereby gaining in notational as well as conceptual simplicity; this approach is carefully described in MIKUSINSKI's textbook 'Operational Calculus' [M 1]. The aims of the present book are the same as MIKUSINSKI's [M 1]: a direct approach requiring no un-necessary restrictions. The present operational calculus is essentially equivalent to the 'calcul symbolique' of distributions having left-bounded support (see 6.52 below and pp. 171 to 180 of the textbook 'Theorie des distributions' by LAURENT SCHWARTZ). 368 pp. Englisch.…

This item is printed on demand - it takes 3-4 days longer - Neuware -The effects of electromagnetic radiation and high-energy par ticles on semiconductors can be divided into two main processes: (a) the excitation of electrons (the special case is internal ioniza tion, i. e. , the generation of excess charge carriers); and(b) dis turbance of the periodic structure of the crystal, i. e. , the forma tion of 'structural radiation defects. ' Naturally, investigations of the effects of radiation on semiconductors cannot be considered in isolation. Thus, for example, the problern of 'radiation de fects' is part of the generalproblern of crystal lattice defects and the influence of such defects on the processes occurring in semi conductors. The same is true of photoelectric and similar phe nomena where the action of the radiation is only the start of a complex chain of nonequilibrium electronprocesses. Nevertheless, particularly from the point of view of the experimental physicist, the radiation effects discussed in the present book have inter esting features: several types of radiation may produce the same resul t (for example, ionization by photons and by charged particles) or one type of radiation may produce several effects (ionization and radiation -defect formation). The aim of the author was to consider the most typical prob lems. The subjects discussed differ widely from one another in the extent to which they have been investigated. 240 pp. Englisch. …

This item is printed on demand - it takes 3-4 days longer - Neuware -The University of Manitoba Symposium on Pupillometry was held in Winnipeg, Manitoba, October 17-19, 1973. The seed of the idea was planted in 1967 when Raymond Daly of the University of Windsor first interested me in the utility of the pupil as a dependent measure in psychology. From that time on I have read as much as possible about the pupil and in late 1971 it occurred to me that it might be a good idea to bring together those pupil lary investigators whose research had the greatest impression upon me. This book is one of happier consequences of the Symposium. The guiding principle behind the selection of participants was a blend of three considerations: (1) long standing research or scholarly interest in problems associated with the eye and the pupil; (2) outstanding respect of the participant by his colleagues involved in pupillometric research; and (3) significant contributions to the learned literature. 280 pp. Englisch.…

This item is printed on demand - it takes 3-4 days longer - Neuware -Engineering has long been thought of by the public as a profession tra- ditionally categorized into such branches as electrical, mechanical, chemical, industrial, civil, etc. This classification has served its purpose for the past half century; but the last decade has witnessed a tremendous change. A continuous transition from the practical to the theoretical has made technology overlap with science, and the enlargement of scope and broad- ened diversification have smeared the boundaries between traditional engi- neering and scientific fields. Engineering is rapidly becoming a diversified, multidisciplinary field of scientific endeavor. This has prompted us to regard modern engineering as a science, which has as its ingredients materials, energy, and information. In our complex and technologically-oriented society organizations are flooded with an enormous amount of management information. We are now faced with problems concerning the efficient use of communicated knowledge. The steady growth in the magnitude and complexity of informa- tion systems necessitates the development of new theories and techniques for solving these information problems.We demand instant access to pre- viously recorded information for decision making, and we require new meth- ods for analysis, recognition, processing, and display. As a consequence, information science has evolved out of necessity. Concerned with the theoretical basis of the organization, control, stor- age, retrieval, processing, and communication of information both by natural and artificial systems, information science is multidisciplinary in character. It covers a vast area of subject matter in the physical and biological sciences. 368 pp. Englisch.…
