Taschenbuch. Condition: Neu. Neuware -Until recently there was no uniform stability theory. Different approaches to stability problems had been developed in the different branches of mechanics. In the field of elasticity, it was mainly the so called static method and energy method which were used, while in the field of dynamics it was the kinetic method, which found its perfect expression in the theory of Liapunov. During the last few decades there has been a rapid development in the general theory of stability, stimulated, for example, by the investigations of H. ZIEGLER on elastic systems subject to non-conservative loads, and by the problems arising in aeroelasticity which are closely related to those introduced by ZIEGLER. The need was felt for kinetic methods which could also be used in investigating the stability of deformable systems. Efforts were made to adapt such methods, already known and developed in the stability theory of rigid systems, for application in the stability theory of continuous systems. During the last ten years interest was focused mainly on the application of a generalized Liapunov method to stability problems of continuous systems. All this was done in attempts to unify the various approaches to stability theory. It was with the idea of encouraging such a tendency, establishing to what extent a uniform physical and mathematical foundation already existed for stability theory in all branches of mechanics, and stimulating the further deve lopment of a common stability theory, that a IUTAM-Symposium was devoted to this topic.

This item is printed on demand - it takes 3-4 days longer - Neuware -Carbon has always been a unique and intriguing material from a funda mental standpoint and, at the same time, a material with many technological uses. Carbon-based materials, diamond, graphite and their many deriva tives, have attracted much attention in recent years for many reasons. Ion implantation, which has proven to be most useful in modifying the near surface properties of many kinds of materials, in particular semiconductors, has also been applied to carbon-based materials. This has yielded, mainly in the last decade, many scientifically interesting and technologically impor tant results. Reports on these studies have been published in a wide variety of journals and topical conferences, which often have little disciplinary overlap, and which often address very different audiences. The need for a review to cover in an integrated way the various diverse aspects of the field has become increasingly obvious. Such a review should allow the reader to get an overview of the research that has been done thus far, to gain an ap preciation of the common features in the response of the various carbon to ion impact, and to become aware of current research oppor allotropes tunities and unresolved questions waiting to be addressed. Realizing this, and having ourselves both contributed to the field, we decided to write a review paper summarizing the experimental and theoretical status of ion implantation into diamond, graphite and related materials. 216 pp. Englisch.

The reader should therefore be able to gain quickly an insight into the important results and techniques in each area without recourse to the large research literature. Current (unsolved) problems are also described and directions for future research are given. This book is also suitable for professional mathematicians who require a succint and accurate account of recent research in areas parallel to their own, and graduates in mathematical sciences.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 304 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - Print on Demand Titel. Neuware -Volume therapy or infusion therapy is used worldwide for the treatment of hypovolemia caused by surgical blood and plasma losses, trauma, burns, or infections. Interestingly, significant differences exist between countries regarding the use of plasma substitutes. In the United States, crystalloids and albumin are more popular, whereas in Europe artificial colloids such as hydroxyethyl starch are preferred. From an international perspective, it is notable that volume therapy using hydroxyethyl starch is an established therapy for the treatment of cerebral, retinal, otogenic, and peripheral circulation disorders in Germany. In other countries, crys talloids are mostly used to treat dehydration or hypovolemia, for example in brain stroke. In recent years, new data made it possible to overcome national differences and agree on an evidence-based, international con sensus. The efficacy of different plasma substitutes for a volume therapy last ing several days has not been sufficiently studied in the past. Long-term volume therapy of patients with cerebral perfusion disorders is an excel lent model for studying the effects of artificial colloids in detail, because of the high doses of colloids that are administered. Through a compari son of commonly used plasma substitutes, we were able to show that sig nificant differences exist between different colloids, for example in their effect on coagulation. After repeated infusion, hydroxyethyl starches that are difficult to degrade lead to an accumulation of large molecules that are difficult to eliminate. These large molecules impair factor VIII/von Willebrand factor.Springer-Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 164 pp. Englisch.

Neuware -Over the past 15 years, a multitude of new transluminal techniques have been developed, all designed to broaden the range of indications and improve the results of angioplasty. Among these, the implantation of intravascular stents has emerged as the technique with the greatest promise. It has become clear that stenting not only successfully deals with the problem of abrupt closure after angioplasty, but also reduces the incidence of restenosis, the Achilles heel of angioplasty. The reason why restenosis is reduced may be because the immediate gain of luminal diameter is greater with stenting than with any other technique. Even if the late loss of diameter is similar among most currently used transluminal techniques, the end result will stilI be better after stenting because of the nearly ideal primary effect. The aims of this book are twofold: first it presents a state-of-the-art summary of the progress made in stenting so far, and secondly it details some of the prospects for future improvement. The concept of stenting has proved to be a correct one, and therefore alI future efforts wilI be directed towards new, safe, and biologicalIy 'friendly' stents.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 192 pp. Englisch.

New methods which will be more sensitive andspecific in the diagnosis of the infection are beingdeveloped and in this proceedings the first attempt usingPCR technology is published. From the clinical point ofview, a challenging aspect that needs clarification, is theobservation which suggests an appearance of a correlationbetween the presence of the bacteria and abdominal pain andother symptoms in children whereas in old age no suchcorrelation is evident. The relationship of H. pylori andgastric cancer is studied with histopathological data andepidemiological approaches. On the treatment side schemesusing short courses and new antibiotic combinations arebeing investigated and preliminary data are reported. 420 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Harderian glands, first described by Jacob Harder in two species of deer in 1694, are large, intraorbital glands which, with but few exceptions, are found in all land vertebrates. Certainly, their relatively large size, their phylogenetic age, and persistent conservation in all groups as they emerged from an aqueous to an air/land environment lend strong support to the logical deduction that they probably play an important role in the physiological adaptation to terrestrial life. Yet, few biologists know even what or where these glands are. For a variety of reasons, the Harderian glands have not received the attention they deserve and, as a result, the published works available have been scarce and scattered throughout the world literature. The current situation is remarkably similar to that which existed in regard to the pineal gland prior to the mid-1960s, i. e. , scattered literature, unknown function, few investigators, and little interest. Yet, following a few key papers, interest in the pineal gland expanded and soon an explosive increase in the knowledge and understanding of the pineal gland took place and continues today. Will history repeat itself Originally, a few of us discussed the desirability of an informal Symposium on the Harderian glands. 344 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -A Symposium on Aerothermodynamics of Combustors was held at the Institute of Applied Mechanics of the National Taiwan University from 3 to 5 June 1991 and was attended by 130 delegates from eight countries. The topics of the forty formal presentations included measurements and calculations of isothermal simulations and of combusting flows with one and two phases, and with consideration of configurations ranging from simple diffusion to gas-turbine flows. The discussions inside and outside of the Symposium Hall were lively and an open forum session demonstrated the range of opinions currently and strongly held. The International Union of Theoretical and Applied Mechanics initiated the Symposium under the chairmanship of Professor R S L Lee and with the Scientific Committee listed below. It benefited from sponsorship, again as listed below, and from contributors who presented interesting and up-to-date descriptions of their research. Invited lectures were delivered by Professors R Bilger and F Weinberg and set the scene in terms of quality of material and presentation. 368 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Progress in science is often promoted by a new method. Diagnostic cytology, however, developed slowly over a whole century, mainly in differentiating malignant from benign cells from various tissues. The decisive step in this development was the intensive investigation of one local ization by Papanicolaou: The application of cytology for screening in the field of gynecologic oncology made it an acknowledged technique. Consequently, materials inves tigated before were tested again on a larger scale and new ones were included into the program. The possibility of a wide-range application of this diag nostic method, which carries a low risk for the patient and is low in cost, attracted the specialists of many fields. One of the problems which has resulted is the coordination of training and quality assurance for a large group of people from different fields and with different interests and whose experience in morphology varies. In this volume general problems of cytology are dis cussed, as is the question 'who is a medical cytologist ' Education and training are the topics of the contributions by Coleman, Holzner, Jenny, Koss and Muller, cover ing the situation in the European Community, Germany, Austria, Switzerland, and the USA. A special contribu tion by Lange concerns the situation of cytotechnologists, paramedicals important for cytologic screening programs. 180 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The important role that satellites play in the field of communications will be manifested by a large number of new satellite systems to be implemented within the next few years. These new systems will basically belong to two categories: (i) satellite networks for mobile/personal communications, mainly with handheld terminals, and (ii) satellite networks for broadband multimedia communications, mainly for fixed but also for portable and mobile terminals. This book gives an overview of both families of satellite systems. In Part I, the basics of geostationary and non-geostationary satellite constellations are dealt with, as well as the principles of satellite communications. Part II deals with satellite systems for mobile/personal communications and ad dresses various aspects of networking (multiple access, cell structure, routing, etc.); it also deals with technology, regulation, and financing. Part III is ded icated to future satellite systems for broadband communications (Internet, multimedia) and discusses satellite-specific aspects of broadband communi cations, in particular on the basis of ATM and TCP /IP. A survey of existing and planned satellite systems completes the book. The authors of this book are scientists at the German Aerospace Center, DLR (Deutsches Zentrum fiir Luft- und Raumfahrt) and work in the Digital Networks group of the Institute for Communications and Navigation. 452 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book contains a selection of papers presented at the Computer Graphics and Education '91 Conference, held from 4th to 6th Apri11991, in Begur, Spain. The conference was organised under the auspices of the International Federation for Information Processing (IPIP) Working Group 5.10 on Computer Graphics. The goal of the organisers was to take a forward look at the impact on education of anticipated developments in graphics and related technologies, such as multimedia, in the next five years. We felt that at a time when many educational establishments are facing financial stringency and when major changes are taking place in patterns of education and training, this could be valuable for both educators and companies developing the technology: for educators, because they are often too bogged down in day-to-day problems to undertake adequate forward planning, and for companies, to see some of the problems faced by educators and to see what their future requirements might be. 308 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -For many decades scholars from various disciplines have been intrigued by the question whether there are unifying principles or models that have a validity in different disciplines. The building of such analytical frameworks bridging the gaps between scientific traditions is a very ambitious task and has not been very successful up till now. In the past - in a static context - several such principles have been defined and advocated at the edge of the natural sciences on the one hand and social sciences (in particular, economics and geography) on the other hand, mainly based on the paradigm of 'social physics'. Some important contributions to the integration of the spatial systems sciences and physics can be found in gravity theory and entropy theory, which have formed the comer stones of interaction models in space. This book is about spatial interaction models. It describes the origin, the history and the correspondence of such models from a 'social physics' perspective. It is emphasized that such models need a clear behavioural underpinning as a sine qua non for a valid use in spatial systems analysis. This view also explains the use of micro-based disaggregate choice models as a tool for analyzing spatial systems. This is mainly analyzed in Part A of this book. 296 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -Volumes five and six of Bioorganic Marine Chemistry differ from their predecessors in two respects - they deal exclusively with labor atory synthesis of marine natural products and they represent the effort of a single author and his associates. The rationale for these departures is readily perceived. For several decades organic synthesis has without doubt been the most spectacular branch of organic chemistry. While the late R.B. Woodward's dictum - organic compounds can undergo only four basic reactions: they can gain electrons; they can lose electrons; they can be transformed with acid or with base - is still true, the wealth and variety of available reagents which will accomplish chemical transformations has reached staggering proportions. Little wonder then, that synthetic methodology has achieved a high degree of predictability and total synthesis of natural products has been successfully directed toward ever more challenging targets. As for the second point, that of single authorship, multiple authorship would invariably have led to gaps and overlaps, thus making it difficult to assemble and assess recent research in a systematic and comprehens ive fashion. 296 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -This book is the first comprehensive description of development of the Acipenserid fish published in the English language. It con tains the results of more than 40 years of studies by the authors and their colleagues. My own life in science has been intimately related both with the authors and the fish, which are the subject of this book. Therefore, it gives me a great pleasure to present to the English reader an expanded version of the book. Those interested in the history of biology must be well aware of the fact that genetics in the USSR was practically demolished by Lysenko at the session of the Lenin All-Union Academy of Agricultural Sciences in 1948. However, it is much less well known that other fundamental branches of biology were also persecuted at that time, experimental embryology (developmental mechanics) among them. As a result, many embryologists, in cluding the authors of this book, were forced to turn to more ap plied problems, this being the only way to continue research. They had to abandon amphibians and concentrate their efforts on sturgeon. 320 pp. Englisch.

Neuware -This book provides an original legal analysis of child soldiers recruited into armed groups or forces committing mass atrocities and/or genocide as the victims of the genocidal forcible transfer of children. Legal argument is made regarding the lack of criminal culpability of such child soldier 'recruits' for conflict-related international crimes and the inapplicability of currently recommended judicial and non-judicial accountability mechanisms in such cases. The book challenges various anthropological accounts of child soldiers' alleged 'tactical agency' to resist committing atrocity as members of armed groups or forces committing mass atrocity and/or genocide. Also provided are original interpretations of relevant international law including an interpretation of the Rome Statute age-based exclusion from prosecution of persons who were under 18 at the time of perpetrating the crime as substantive law setting an international standard for the humane treatment of child soldiers.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 320 pp. Englisch.

Neuware -Predation is an ecological factor of almost universal importance for the biol ogist who aims at an understanding of the habits and structures of animals. Despite its pervasive nature opinions differ as to what predation really is. So far it has been defined only in negative terms; it is thought not to be par asitism, the other great process by which one organism harms another, nor filter-feeding, carrion-eating, or browsing. Accordingly, one could define predation as a process by which an animal spends some effort to locate a live prey and, in addition, spends another effort to mutilate or kill it. Ac cording to this usage of the word a nudibranch, for example, that feeds on hydroids would be a predator inasmuch as it needs some time to locate col onies of its prey which, after being located, scarcely demand more than eating, which differs little from browsing. From the definition just proposed consumption of the prey following its capture has been intentionally omit ted. Indeed, an animal may be disposed of without being eaten. Hence the biological significance of predation may be more than to maintain nutrition al homeostasis. In fact, predation may have something in common with the more direct forms of competition, a facet that will be only cursorily touched upon in this book.Springer-Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 264 pp. Englisch.

Neuware -The monograph being proposed for the English-speaking research community is concentrated on the atmospheric correction of satellite images as a part of thematic interpretation procedures while processing remote sensing data. For linguistic reasons a large section of the community may have been unaware of the progress made in Russia in this field of science and technology. Meanwhile, Russia was the first country to launch the first artificial satellite in 1957 and to obtain from space for the first time spectra of the Earth's atmosphere in the 1960's. New applications of the radiation transfer theory for the atmosphere underlying surface system appeared first in Russia in the 1970's. Direct and in verse problems of the atmospheric optics were then formulated giving the scientific basis for studies of natural resources from space. Since that time new mathematical treatments for the atmospheric correction procedures have been widely developed in Russia, including both analytical and numerical tech niques to simulate spectral, angular, and spatial distributions of the outgoing radiation in visual and infrared regions. The authors of the book were at the beginning of the scientific approach. A wide range of mathematical im provements to elaborate polinomial approximations for dependencies between atmospheric radiation field and parameters of space surveying was due to the necessity to process satellite images in real time using special software of ex isted computer means for the studies.Springer-Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 496 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - Print on Demand Titel. Neuware -This book is a study of plasma waves which are observed in the earth's magnetosphere. The emphasis is on a thorough, but concise, treatment of the necessary theory and the use of this theory to understand the manifold varieties of waves which are observed by ground-based instruments and by satellites. We restrict our treatment to waves with wavelengths short compared with the spatial scales of the background plasma in the mag netosphere. By so doing we exclude large scale magnetohydrodynamic phenomena such as ULF pulsations in the Pc2-5 ranges. The field is an active one and we cannot hope to discuss every wave phenomenon ever observed in the magnetosphere! We try instead to give a good treatment of phenomena which are well understood, and which illustrate as many different parts of the theory as possible. It is thus hoped to put the reader in a position to understand the current literature. The treatment is aimed at a beginning graduate student in the field but it is hoped that it will also be of use as a reference to established workers. A knowledge of electromagnetic theory and some elementary plasma physics is assumed. The mathematical background required in cludes a knowledge of vector calculus, linear algebra, and Fourier trans form theory encountered in standard undergraduate physics curricula. A reasonable acquaintance with the theory of functions of a complex vari able including contour integration and the residue theorem is assumed.Springer-Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 364 pp. Englisch.

In this work the author has achieved correspondence between sonograms and anatomic sections with a consistency and persuasiveness unequaled in all the previous literature on diagnostic ultrasound. The various planes of section andtheir characteristic features, and indeed the entire format of the text, are designed to provide even the less experienced sonographer with a valuable basis for conducting his examinations. The more experienced reader will find essential information on topographic relations and organ development that is not available in any other work dealing with fetal ana to~y. I am certain that my high estimation of this volume will prove justified, and that it will provice its readers with a useful and stimulating resource. Univ. -Prof. Dr. Walter Thiel (Chairman of the Anatomic Institute of the University of Graz) Foreword Anyone setting this book down after an initial perusal must wonder why such a reference was not available ten years ago. The meticulous and fas cinating juxtaposition of gross anatomic sections with sonograms, together with explanatory drawings and many practical guidelines, should enable even the novice accurately to identify details and interpret sonographic findings with precision.Springer-Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 212 pp. Englisch.

Airline systems are providing faster and more efficient networks for world-wide human transportation. Com puters are now generally accessible to virtually all industries and many households. But perhaps the most important factor is that education systems are expanding the knowledge base for city populations, thus resulting in increased efficiency in the use of computers, telecommuni cations and rapid transportation systems. The revolutionary age of logistical networks is upon lIS. Logistical networks are those systems which facilitate the movement of knowl edge, commodities, money, and people in association with thE; produc tion or consumption of goods and services. Logistical networks form a set of important infrastructure which serve as hard and soft means to sustain all kinds of movement, transactions and diffusion within and between global networks of cities. Major structural changes in the re gional and urban economy, culture and institutions are triggered by slow but steady changes in global logistical systems. 308 pp. Englisch.

Neuware -Secretions and emissions in biological systems play important signaling roles within the organism but also in its communications with the surrounding environment. This volume brings together state-of-the-art information on the role of secretions and emissions in different organs and organisms ranging from flowers and roots of plants to nematodes and human organs. The plant chapters relate information regarding the biochemistry of flower volatiles and root exudates, and their role in attracting pollinators and soil microbial communities respectively. Microbial chapters explain the biochemistry and ecology of quorum sensing and how microbial communities highly co-adapted to plants can aid in bio-energy applications by degrading ligno-cellulosic materials. Other chapters explain the biology of secretions by nematodes, algae and humans, among other organisms. This volume will be a welcome addition to the literature, as no other book covers aspects related to biological secretion in such a holistic and integrative manner.Springer-Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 292 pp. Englisch.

In the 1950s and 1960s, interest in the subject was limited to only a handful of scientists who perceived in dendrochronology a 'l'art pour l'art'. Today, however, specialists from many different fields recognize and are pursuing the problems of dendrochronology. Tree-ring research has acquired a permanent role in the various sciences of archeology, history, geology, ecology, and climatology. The founders of dendrochronology themselves were of varied scientific backgrounds and interests. For example, A. E. Douglass in the United States was an astronomer, B. Huber in Germany a forest-biologist, and F. N. Shvedov in Russia a climatologist. Today the spectrum is even broader. Many den drochronologists are authorities in mathematics, archeology, history, forestry, botany, wood technology, ecology geography, geology, etc. It is, therefore, understandable that it has become almost impossible for one individual to encompass the entire field. Bitvinskas (1974), Fritts (1976), Schweingruber (1983), and Mitsutani (1990) have attempted, each guided by his own interests, to provide at least an overview of the field. Recently, individual aspects have been presented by groups of authors in books edited by Fletscher (1978), Hughes et al. (1982), Jacoby and Hornbeck (1987) and Bradley and Jones (1992). It is very likely that in the future summaries covering each branch of dendrochronology will be published.Springer-Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 416 pp. Englisch.
