This item is printed on demand - it takes 3-4 days longer - Neuware -It is estimated that the functionally significant body of knowledge for a given medical specialty changes radically every 8 years. New specialties and 'sub-specialization' are occurring at approximately an equal rate. Historically, established journals have not been able either to absorb this increase in publishable material or to extend their readership to the new specialists. International and national meetings, symposia and seminars, workshops, and newsletters suc cessfully bring to the attention of physicians within developing spe cialties what is occurring, but generally only in demonstration form without providing historical perspective, pathoanatomical corre lates, or extensive discussion. Page and time limitations oblige the authors to present only the essence of their material. Pediatric neurosurgery is an example of a specialty that has de veloped during the past 15 years. Over this period neurosurgeons have obtained special training in pediatric neurosurgery and then dedicated themselves primarily to its practice. Centers, Chairs, and educational programs have been established as groups of neuro surgeons in different countries throughout the world organized themselves respectively into national and international societies for pediatric neurosurgery. These events were both preceded and fol lowed by specialized courses, national and international journals, and ever-increasing clinical and investigative studies into all aspects of surgically treatable diseases of the child's nervous system. 276 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -The energy short-falls of the 1970's made clear both individual and national vulnerability when reliance is on a single energy source such as petroleum. Further, the situation was a sharp reminder that fossil fuels are finite and that their supplies will become limiting. Whether short supplies are for political, economical, or geological reasons, they signal the need to plan for a future with diverse options so.that needs can be met without disruptive consequences when supplies of one source become limiting. Conservation plays a major role in any strategy; however, it should be recognized that such steps can only 'buy time' by extending the supply - not create new energy supplies. Proven petroleum reserves in the United States currently are stated to be equivalent to only 8~ years consumption at current rates assuming no imports or additional petroleum discoveries. Another important strategy is to develop biomass, solar and other alternative energy supplies and integrate their use into contemporary society. A fundamental difference between fossil fuels and biomass involves the concept of stock versus flow resources. For example, the amount of crude oil is basically a fixed or stock level which is being rapidly mined. 684 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -In the last 40 years geophysicists have found that it is possible to construct images and even determine important physical characteristics of rocks that can yield information about oil and gas bearing structures in the earth. To make these images and extract this information requires the application of an advanced understanding of the mathematical physics of wave propagation. The oil and gas industry labels a major collection of the necessary seismic data processing methods by the name seismic 'migration'. This text ist the first to treat many kinds of migration in a unified mahtematical way. The audience is mathematically oriented geophysicists or applied mathematicians working in the field of 'inverse scattering imaging'. The text can serve as a bridge between the applied math and geophysics community by presenting geophysicists with a practical introduction to advanced engineering mathematics, while presenting mathematicians with a window into the world of the mathematically sophistiated geophysicist. 544 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The problem of moment formation in metallic systems lies at the interface of localized and itinerant magnetism. The phenomena observed correspond to destruction rather than to formation of spin-correlations. They give rise to the progression from local ized ground states through Kondo and mixed-valence behaviour to itinerant magnetic or non-magnetic systems. Somewhere in the pro gression superconductivity can occur in the presence of f-moments. To bring together the disparate ideas and methods, previously the subject of intense debate only at a number of topical confer ences, a two-week Advanced Study Institute was held August 21 - September 02, 1983, at Lester B. Pearson College of the Pacific, Vancouver Island. In the stimulating environment provided by the pines and fiord at the site of this remote United World College on the Canadian West Coast, scientists and students from around the globe gathered to hear lectures by experts. The Study Institute involved seventy-six people and followed in the tradition . of pre vious 'Banff' summer schools organized by the Canadian Association of Physicists. It was made possible by grants from the North Atlantic Treaty Organization, the Natural Sciences & Engineering Research Council of Canada and Atomic Energy of Canada. The grants permitted many young scientists from Nato and non-Nato countries to learn the fundamentals as well as the latest results in the field. 352 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book is intended for undergraduates studying the biological and medical sciences. The field of excitable cell physiology is one which is found quite baffling by a significant minority of these students. My aim here is to provide a brief introductory account, based on a conceptual approach, rather than on a mathematical or historical description. Once the student has grasped certain basic ideas concerning excitable cell function, the individual examples which follow fit into a well-defined pattern. No attempt has been made to give credit in appropriate measure to the many scientists who have contributed to this field. The further reading cited has been chosen with the reader alone in mind. I would like to thank Tim Cripps for help and advice, also Charlie Tomson and Michael Hart for their careful reading of the manuscript. Finally I am indebted to Jenny Kenyon for her excellent typing of the work. Part One THE CONCEPT OF EXCITABILITY INTRODUCTION 1 1.1 The Excitable Tissues living organisms are able to respond to changes in their environment. 164 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The papers in this volume were presented at an International Symposium on Optimal Estimation in Approximation Theory which was held in Freudenstadt, Federal Republic of Germany, September 27-29, 1976. The symposium was sponsored by the IBM World Trade Europe/Middle East/Africa Corporation, Paris, and IBM Germany. On behalf of all the participants we wish to express our appreciation to the spon sors for their generous support. In the past few years the quantification of the notion of com plexity for various important computational procedures (e. g. multi plication of numbers or matrices) has been widely studied. Some such concepts are necessary ingredients in the quest for optimal, or nearly optimal, algorithms. The purpose of this symposium was to present recent results of similar character in the field or ap proximation theory, as well as to describe the algorithms currently being used in important areas of application of approximation theory such as: crystallography, data transmission systems, cartography, reconstruction from x-rays, planning of radiation treatment, optical perception, analysis of decay processes and inertial navigation system control. It was the hope of the organizers that this con frontation of theory and practice would be of benefit to both groups. Whatever success th ~ symposium had is due, in no small part, to the generous and wise scientific counsel of Professor Helmut Werner, to whom the organizers are most grateful. Dr. T. J. Rivlin Dr. P.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -From the Preface: 'The material in this book is based on notes for a course which I gave several times at Brown University. The target of the course was juniors and seniors majoring in applied mathematics, engineering and other sciences. My basic goal in the course was to teach standard methods, or what I regard as a basic 'bag of tricks'. In my opinion the material contained here, for the most part, does not depart widely from traditional subject matter. One such departure is the discussion of discrete linear systems. Besides being interesting in its own right, this topic is included because the treatment of such systems leads naturally to the use of discrete Fourier series, discrete Fourier transforms, and their extension, the Z-transform. On making the transition to continuous systems we derive their continuous analogues, viz., Fourier series, Fourier transforms, Fourier integrals and Laplace transforms. A main advantage to the approach taken is that a wide variety of techniques are seen to result from one or two very simple but central ideas. Above all, this course is intended as being one which gives the student a 'can-do' frame of mind about mathematics. Students should be given confidence in using mathematics and not be made fearful of it. I have, therefore, forgone the theorem-proof format for a more informal style. Finally, a concerted effort was made to present an assortment of examples from diverse applications with the hope of attracting the interest of the student, and an equally dedicated effort was made to be kind to the reader.' 388 pp. Englisch.

Neuware -Nanofins Science and Technology describes the heat transfer effectiveness of polymer coolants and their fundamental interactions with carbon nanotube coatings that act as nanofins. Heat transfer at micro/nano-scales has attracted significant attention in contemporary literature. This has been primarily driven by industrial requirements where significant decrease in the size of electronic devices/chips with concomitant enhancement in the heat flux have caused challenging needs for cooling of these platforms. With quantum effects kicking in, traditional cooling techniques need to be replaced with more effective technologies. A promising technique is to enhance heat transfer by surface texturing using nanoparticle coatings or engineered nanostructures. These nanostructures are termed as nanofins because they augment heat transfer by a combination of surface area enhancement as well as liquid-solid interactions at the molecular scale.Springer-Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 84 pp. Englisch.
