It is and begin with the answers. Then one day, that they can't see the problem. perhaps you will find the final question. G. K. Chesterton. The Scandal of Fother 'The Hennit Clad in Crane Feathers' in R. Brown 'The point of a Pin'. van GWs The Chinese More 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. 268 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -A hundred years have now gone by since in the midsummer of 1882 Pierre Duhem, a graduate of College Stanislas, completed with brilliant success his entrance exams to the Ecole Normale Superieure and embarked on his career as a theoretical physicist. His father, a textile salesman, hoped that Hierre would pursue a career in business, one of the few professional fields where perhaps he would not have succeeded. Not that young Duhem lacked sense for the practical. He could have easily made a name for himself as an artist had he developed professionally his skill to draw portraits and landscapes. His ability to make a point and his readiness to join in a debate, could have earned him fame as a lawyer. A potential actor was in sight when he entertained friends with mimicry. That as a student of physics he entered and stayed first in his class at the Ecole Normale, did not thwart his talents for the life sciences. No less a biologist than Pasteur tried to obtain Duhem for assistant. His command of Greek and Latin would have secured him a career as a classicist. He was a Frenchman, not to be met too often, whose rightful ad miration for and mastery of his native tongue, did not prove a barrier to the major modern languages. As one who taught himself the complex art of medieval paleo graphy, he could easily have mastered the many auxiliary sciences needed by a consummate historian. 488 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The Symposium was held at the Great Wall Sheraton Hotel in Beijing, China in the period August 25-30, 1986. The decision to concentrate on the observational aspects of modern cosmology was taken in part because this conference has come in a period when there have been several international meetings on one aspect of modern cosmology, namely the early universe and its possible relationship to particle physics. While that approach is extremely exciting, it has the disadvantage that its connection with much of observational cosmology is very indirect. Thus there has been little opportunity to discuss critically the wealth of new data that are now becoming available which bear on the structure and evolution of the Universe but not always on its early history. This Symposium was planned to cover all aspects of observational cosmology, with only comparatively minor excursions into theory. Nearly 200 participants attended from 21 countries. A total of 26 invited papers and 73 contributed papers were given. This meant that everyone worked hard and long from 9 A.M. to about 5:30 P.M. for five of the six days of the conference. In addition to oral contributions, space was made available for poster papers and 56 of these were available for study for the duration of the conference. 884 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This is an inadvertent book, though it did arise naturally enough from a course I give in theoretical ecology. But I wouldn't have given the course at all if one colleague in my department hadn't left for a leave of absence, while another abruptly resigned. This propelled me to the fore where this teaching responsibility was concerned, one I had never had any intention of discharging. Then it turned out that one of my students was regularly unable to make half the classes. As a result, I began giving him my lecture notes each week. As I knew that someone else would be reading them, I began to write my notes more carefully. Naturally enough, the other students soon began to demand the notes too. Eventually they were indulged. Thus I found myself writing a textbook manuscript. By the next year, the students were handed all their notes in one package at the outset. But these were still just hand-written. Inevitably, the demand that they be typed arose. This I didn't want to do until I found a publisher. As it turned out, Tim Hardwick of Croom Helm was willing to have his firm fill this role, to my great satisfaction. - and his considerable frustration. I have been a desultory author about producing this final text, and can only express my gratitude for his enduring patience over more than 18 months of delays. 220 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The importance of CAD to electronics technology Computer-aided design (CAD) is one way of coping with the problem of how to design and build very complex systems. This problem is particularly acute in electronics technology. Designs are now (1984) said to be design-limited, rather than technology-limited. It can take months to generate a design for a chip, so that it might be obsolete before it can be manufactured. Manual design of large-scale integration (LSI) chips (circa 10,000 gates) is almost impossible. However, using current technology it is possible to produce chips having 250,000 gates. It is understandable, therefore, that there is great interest in improving existing CAD systems. Designers of CAD systems are concerned with formalizing and automating as much of the design task as possible. Automating design of any kind has long been acknowledged as a project fraught with intractable problems. A human designer has to have an understanding of the nature of the materials used in manufacture, a knowledge of common problems and well-tried solutions, and above all, creativity in producing new designs. Understanding, knowledge and creativity are three properties even the most artificially intelligent of computer programs have been entirely lacking in until very recently. Some people would deny computers these qualities entirely, on philosophical grounds (eg Dreyfus 1979; Searle 1981). There are few theories in cognitive psychology which can help. 120 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The use of sensor's with machines, whether to control them continuously or to inspect and verify their operation, can be highly cost-effective in particular areas of industrial automation. Examples of such areas include sensing systems to monitor tool condition, force and torque sensing for robot assembly systems, vision-based automatic inspection, and tracking sensor's for robot arc welding and seam sealing. Many think these will be the basis of an important future industry. So far, design of sensor systems to meet these needs has been (in the interest of cheapness) rather ad hoc and carefully tailored to the application both as to the transducer hardware and the associated processing software. There are now, however, encouraging signs of commonality emerging between different sensor application areas. For instance, many commercial vision systems and some tactile systems just emerging from research are able to use more or less standardized techniques for two-dimensional image processing and shape representation. Structured-light triangulation systems can be applied with relatively minor hardware and software variations to measure three-dimensional profiles of objects as diverse as individual soldered joints, body pressings, and weldments. Sensors make it possible for machines to recover 'sensibly' from errors, and standard software proce dures such as expert systems can now be applied to facilitate this. 184 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The contemporary industrial robot is the focal point of a wide variety of elements in modern technology. It is a collection of parts, some of which act as drives and some of which act as architectural materials that give the robot body strength. This book is a thorough inventory of the technologies involved and the way in which they meet and work together in order to produce a functional robot arm. The authors have striven to describe thoroughly the components that make up robot arms. This gives both the student and the practitioner a complete view of the principles involved in such components and the differences between existing technologies. However, it is not only the student who benefits from this approach but also the potential robot user who, at the moment, may be faced with a bewildering choice of combinations of different types of components in the robots that are available to him. For example, it is difficult for a production manager to appreciate the differences between robots that use direct current motors, stepping motors and pneumatic actuators. The authors have succeeded in structuring the book so that the reader can weigh up the pros and cons of these different techniques at whatever level of depth he requires. Certainly, the book aims to provide as much depth as there is in these topics without assuming a detailed knowledge of specialized areas of engineering. 348 pp. Englisch.

If your heels are nimble dnd light, You may get there by candle-light. Any philosopher who takes more than a fleeting interest in the sciences and their development must at some stage confront the issue of incommensurability in one or other of its many manifes tations. For the philosopher of science concerned with problems of conceptual change and the growth of knowledge, matters of incommensurability are of paramount concern. After many years of skating over, skimming through and skirting round this issue in my studies of intertheory relations in science, I decided to take the plunge and make the problem of incommensurability the central and unifying theme of a book. The present volume is the result of that decision. My interest in problems of comparability and commensurability in science was awakened in the formative years of my philosophi cal studies by my teacher, Jerzy Giedymin. From him I have learnt not only to enjoy philosophical problems but also to beware of simpleminded solutions to them. The vibrant seminars of Paul Feyerabend held at Sussex University in 1974 left me in no doubt that incommensurability was, and would remain, a major topic of debate and dispute in the philosophical study of human knowledge. 276 pp. Englisch.

Buch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The following pages attempt to develop the main outlines of an existential phenomenology of law within the context of Maurice Merleau-Ponty's phe nomenology of the social world. In so doing, the essay addresses the rather narrow scholarly question, If Merleau-Ponty had written a phenomenology of law, what would it have looked like But this scholarly enterprise, although impeccable in itself, is also transcended by a more complicated concern for a very different sort of question. Namely, if Merleau-Ponty's phenomenological descriptions of the social world are correct-as I believe they largely are-then what are the philosophical consequences for an adequate understanding of law Such a project may well occasion a certain surprise amongst observers of the contemporary philosophical landscape, at least in what concerns the terrain of continental thought, and for two different reasons. The first is that, although interest in Merleau-Ponty's work remains strong in the United States and Can ada, his philosophical standing in his own country has been largely eclipsed! by that of, first, his friend/estranged acquaintance, Jean-Paul Sartre; by various Marxist philosophies and critical social theories; and finally by those doing her meneutics of language. In my view, current neglect of Merleau-Ponty's thought in France is most regrettable. 260 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The idea for an international symposium on the interstellar medium was first discussed at the University of Wyoming during the summer of 1984. It was obvious that the outstanding natural beauty of the Teton mountain range in northwestern Wyoming must be matched by a meeting with the broadest appeal to the astronomical community. If the meeting was to produce a book, it must likewise be an important contribution to the astronomical literature. It was for these reasons that early in the discussions, it was decided that the University should host a 'school'. with the invited speakers presenting tutorials on a broad range of topics involving the interstellar medium. The symposium proceedings would then be a compilation of the written versions of these presentations. It has been nearly a decade since Lyman Spitzer published his classic text on the interstellar medium and we felt the need for a school and book that would focus on the recent developments in our understanding of the inter stellar medium. Thus, we view this two-volume set as an adjunct text to Spitzer's book. 824 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -There is little more than a decade left before the bells allover the world will be ringing in the first hour of the twenty-first century, which will surely be an era of highly advanced technology. Looking back on the century that we live in, one can realize that generations of people who have already lived in it for the better parts of their lives have begun to ask the same question that also every individual person thinks about when he is faced with the first signs of the end of his life. It is the question: 'Why did everything in my life happen the way it did ' Or, 'It would have been so easy to have channelled events into directions other than the way they went. ' Or, 'Why, in all the world, is my life coming to an end as it does, or, why must all of us face this kind of end of our century ' Whenever human beings take retrospective views of their lives and times - when they are faced with their own personal 'fin du siecle' - there appears to be an increasing anxiety throughout the masses asso ciated with a somber feeling of pessimism, which may even be mixed with a slight degree of fatalism. There is quite another feeling with those persons who were born late in this century and who did not share all the events the older generation experi enced. 164 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Some fifteen years ago, research on generalized quantifiers was con sidered to be a branch of mathematical logic, mainly carried out by mathematicians. Since then an increasing number of linguists and philosophers have become interested in exploring the relevance of general quantifiers for natural language as shown by the bibliography compiled for this volume. To a large extent, the new research has been inspired by Jon Barwise and Robin Cooper's path-breaking article 'Generalized Quantifiers and Natural Language' from 1981. A concrete sign of this development was the workshop on this topic at Lund University, May 9-11, 1985, which was organized by Robin Cooper, Elisabet Engdahl, and the present editor. All except two of the papers in this volume derive from that workshop. Jon Barwise's paper in the volume is different from the one he presented in connection with the workshop. Mats Rooth's contribution has been added because of its close relationship with the rest of the papers. The articles have been revised for publication here and the authors have commented on each other's contributions in order to integrate the collection.

Although the life cycles of most helminths of zoonotic importance are well known, there are still major gaps in our knowledge especially in the fields of epidemiology, diagnosis and treat ment The International Colloquium on Helminth Zoonoses held at the Institute of Tropical Medicine, Antwerp, 11-12 December 1986, laid emphasis on more recent advances made in the control and epidemiology of these zoonotic diseases. The disease complexes echinococcosis/hydatidosis, taeniasis/cysticercosis and the larva migrans-syndrome were dealth with in considerable detail. In the first chapter the phenomenon of strain variation in Echinococcus spp. is examined in the light of newer findings. The progress made in recent years towards a more specific diagnosis and drug targeting in hydatidosis is reported. In the second chapter recent advances in immunisation and treatment of cysticercosis are dealt with. The possibili ty of the existence of strain differences in Taenia saginata is also dis cussed. The third chapter is devoted to trematode zoonoses with particular reference to the situation in South-east Asia, Senegal (schistosomiasis) and Liberia (paragonimiasis). In the last chapter the larva migrans syndrome is treated in detail with special attention to its etiology and and diagnosis. Reports on lesser known nematode zoonoses like mammomono gamosis and oesophagostomiasis are included. 260 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -This NATO-ASI on BIOPOLYMERS STRUCTURE AND DYNAMICS held between 22nd June 4th July 1986 at Erice (Italy) has brought together scientists from a broad variety of biophysical disciplines - polymer physics, biophysics and physical chemistry, structure and dynamics of polynucleotides, proteins, and polysaccharides - to present the current state of knowledge in their fields, both experimental and theoretical. This Advanced Study Institute was indeed a successfull attempt to enhance the possibility of intersection of a number of research lines that currently are progressing well but are still running largely in parallel with one another: protein folding, single-polymer phase transitions, DNA condensation into liquid crystalline-like arrays, packaging in viruses, and polysaccharide gel formation. Although each phenomenon is distinctive, an awareness of similarities may lead to new ic;leas. The program has emphasized 'condensed' forms of biopolymers. We are universally confronted in biology by chain polymers folded on themselves or interlinked in gel-like assemblies, whether we look at the native structure of proteins, the role of polysaccharides in connective tissue, or the genetic apparatus. A number of lectures have been devoted to condensed forms of DNA - closed circular supercoils, toruses, chromatin. 282 pp. Englisch.

Buch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This publication contains a collection of 22 manuscripts by authors invited to write review articles. They are based on lectures presented on the First and Second Training Course in Radiopharmacy and Radiopharmacology. These courses were organized under the auspices of the 'Joint Committee on Radiopharmaceuticals' of both European Societies of Nuclear Medicine (ENMS and SNME) and were sponsored by the European Society of Nuclear Medicine (ENMS). Recent developments in radiopharmacy and radiopharmacology have been very complex; they cannot be overlooked by the medical staff in nuclear medical departments. This book has been written to provide access to recent research and to practical daily routine in patients' investigations. It provides a wide-ranging and topical overview of radiopharmacology in cluding chapters on basic chemistry and physics, incorporation dosimetry, interference of drugs in radiopharmacokinetics, legal aspects and stable isotope-labelled pharmaceuticals. Style of presentation is not uniform. Par tial overlapping concerning the content of papers has not been avoided in order to ensure different views and aspects of the same subject. We hope that the interdisciplinary approach will be stimulating and thought-provok ing for the reader. Consequently, this book is designed for specialists work ing in nuclear medical centres which involve different disciplines such as pharmacists, radiochemists, physicists, biochemists, biologists, mathemati cians, electronic engineers, physicians with different specialities, and tech nicians. 266 pp. Englisch.

In order to understand his metaphysics, it would he better to read The Theory of Categories; in order to master the finer points of his psychology, it would be better to read Psychology From an Empirical Standpoint; in order to appreciate his ethical theory, it would be better to read The Origin of Our Knowledge of Right and Wrong or, for a more thorough treatment, The Foundation and Construction of Ethics. But in order to see what it was that gave Brentano the enthusiasm and dedication to do all that work and much more besides, it is necessary to find out what Brentano believed the philosophical enterprise itself to be; and this comes forth most vividly when he bends his philosophical efforts to the subject he considered most important of all, namely, natural theology. For, like Socrates, Brentano brought a kind of religious fervor to his philosophy precisely because he saw it as dealing much better than religion does with the matters that are closest to our hearts. 372 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -The Milky Way Galaxy offers a unique opportunity to study the structure and contents of a major stellar system in three dimensions, at high spatial and spectral resolution, and to very large galactocentric distances. This potential can be realised only by statistical surveys of large areas of the sky, and by detailed study of specific regions with exceptional properties, such as the Galactic centre, and of specific classes of object, such as the globular clusters. The acquisition of such data from a variety of ground-based and satellite surveys has been a primary topic of Galactic research for some years. Several such surveys have been completed recently, and have led to a substantial modification of our understanding of Galactic structure and evolution. The importance of the ability of satellite observatories to survey and to study wavelengths which are inaccessible from the ground is evident in the wealth of data discussed and analysed in this volume which is derived from satellites, specifically COS-B, HEAD-I, HEAO-3, IRAS, PIONEER-lO, SAS-2, and TENMA. The cru cial role of ground-based observations to complement and comprehend the satellite data is also well evident. Similarly, the major ground-based studies whose results are reported here illustrate the necessity for carefully conceived and executed very large scale surveys of many types of object and many parts of parameter space before a coherent picture of the Galaxy will be available. 456 pp. Englisch.

Prechtl with the help of the International Cerebral Palsy Society organized an international conference on 'New develop ments in the assessment of early brain damage' in Bled, Yugo slavia. I was invited as a speaker at this conference and I went there, curious, but without too much knowledge about the central theme: cerebral palsy. During the conference and a satellite meeting I became impressed by the quality of various contributions and also by the great variety of problems related to the etiology, early diagnosis, management and psychosocial aspects of cerebral palsy. Today, in many areas of biology and medicine, progress seems to require concentration on a very narrow field. As a consequence many conferences are highly specialized and most (young) scientists rightly consider this as most useful for their own work. On the other hand the care of patients and counselling of parents and other close relatives require a multidisciplinary approach. Also, advances in the study of complicated un resolved medical biological pr'oblems are often made unex pectedly by using ideas, theories, approaches or methods from other disciplines. 164 pp. Englisch.

The workshop was financed by the Commis sion of the European Communities from its budget for the coordina tion of Community Agricultural Research and the Agricultural Uni versity of Wageningen (The Netherlands). Its aim was to bring together experts from different disciplines all having in common that in one way or another they were involved in stress research. Such a multidisciplinary encounter should not only provide an interesting description of present day knowledge on stress, but also promote a more integrated view on stress phenomena as they occur in higher vertebrates. In the course of this workshop the following fields of research were related to stress: endocrinology, immunology, pathology, neurobiology, ethology and theoretical bio logy. Each of these relationships was introduce& by one speaker presenting a concise state of the art. The same relationship was elaborated by a second speaker implementing the available knowledge as far as possible to the farm animal situation. Therefore in this book each discipline is represented by a duo and introduced by some integrating remarks. 212 pp. Englisch.

Failure, faults, seismic waves and all processes involving inertial terms will not be dealt with. In general such scientists (graduate students beginning a Ph. D. for instance) have too small a background'in continuum mechanics and in numerical computation to model conveniently these problems, which are not elementary at all. Most of them are not linear, and therefore seldom dealt with in treatises. If the study of reality were clearly cut into two successive steps: first to make a physical model, setting up a well-posed problem in thermo-mechanics, and second to solve it, the obvious solution would be to find a specialist in computational mechanics who could spend enough time on a problem which, although maybe crucial for on-going fundamental research, has little practical interest in general, and cannot be considered properly as a noteworthy progress in Mechanics. But this is not the way Science develops. There is a continuous dialectic between the building up of a model and its mathematical treatment. The model should be simple enough to be tractable, but not oversimplified. Its sensitivity to the different components it is made of should be investigated, and more thought is needed when the results contradict hard facts. 534 pp. Englisch.
