Ein solches Vorurteil vergisst, dass es auch andere Wirklichkeiten gibt. Ist unsere Welt ein Blick durch ein Kaleidoskop Wie kann es sein, dass man eine mehr oder minder große Auswahl panoramenhafter Wirklichkeiten vor sich hat Ist es möglich, solche Wirklichkeiten zu verlassen und in andere überzuwechseln Anhand konkreter Beispiele wird dieser Wirklichkeits-Pluralismus beleuchtet. Das erste Beispiel, ein astronomisches, zeigt in aller Ausführlichkeit, auf welche Weise Wirklichkeit entstehen kann. Dann ist von anderen naturwissenschaftlichen Wirklichkeiten die Rede, vom Licht und von der Farbe sowie von einer fremden heilkundlichen Wirklichkeit.Ein zentrales Anliegen von Gerhard Fasching ist ein Denken, welches in einen Wirklichkeitspluralismus mündet. Unser monokulturelles Wirklichkeitsverständnis hat nämlich schon viele Wirklichkeiten unserer eigenen Kultur und fremder Kulturen missachtet und dadurch verloren. Unser humanistisches Weltbild benötigt also ein breiteres Fundament.Das Buch findet zu einem überraschenden Ergebnis: Man selbst gehört nicht zur Wirklichkeit, sondern man steht stets außerhalb jeder Wirklichkeit.GERHARD FASCHING. Geb. 1933 in Wien, Univ.-Prof. Dipl.-Ing. Dr. techn., 1966 Habilitation, seit 1970 Ordinarius an der Technischen Universität Wien, Österreich.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -As an addition to the European postgraduate training system for young neurosurgeons we began to publish in 1974 this series devoted to Advances and Technical Standards in Neurosurgery which was later sponsored by the European Association of Neurosurgical Societies. The fact that the English language is well on the way to becoming the international medium at European scientific conferences is a great asset in terms of mutual understanding. Therefore we have decided to publish all contributions in English, regardless of the native language of the authors. All contributions are submitted to the entire editorial board before publication of any volume. Our series is not intended to compete with the publications of original scientific papers in other neurosurgical journals. Our intention is, rather, to present fields of neurosurgery and related areas in which important recent advances have been made. The contributions are written by specialists in the given fields and constitute the first part of each volume. In the second part of each volume, we publish detailed descriptions of standard operative procedures, furnished by experienced clinicians; in these articles the authors describe the techniques they employ and explain the advantages, difficulties and risks involved in the various procedures. This part is intended primarily to assist young neurosurgeons in their post graduate training. However, we are convinced that it will also be useful to experienced, fully trained neurosurgeons. 280 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Our common interest in surgery of the vertebral artery was born in 1976, when as residents in the same hospital, we attended an attempt by two senior surgeons to treat an aneurysm of the vertebral artery at the C 3 level. Long discussions had preceded this unsuccessful trial, to decide if surgery was indicated and to choose the surgical route. Finally a direct lateral approach was performed, but access was difficult and correct treatment was impossible, resulting in only partial reduction of the aneurysmal pouch. Following this experience, we decided to seek a regular and well defined approach for exposition of the vertebral artery. Review of the literature indicated some surgical attempts, but the descriptions did not give the impression of safety and reproducibility. No landmark on the described surgical route appeared sufficiently reliable. Henry's anatomical work (1917) gave the only accurate description on vertebral artery anatomy, and it became the basis for our work. When the same patient was referred again one year later, after a new stroke in the vertebro-basilar system, we had behind us repetitive experience on cadavers of an original approach to the distal vertebral artery. 272 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book attempts to combine many different threads into a comprehensible whole. Since the subject is the Gamma Knife and the author is a neurosurgeon, the field of clinical interest is restricted to intracranial pathology. The discipline of radiosurgery now applies to patients who may reasonably be referred by internists, neurologists, otolaryngologists, endocrinologists and several others. Some of the topics, touched upon, such as stereotaxy and the construction of a radio surgical instrument are unfamiliar to the majority of medical men. Other topics, such as those pertaining to the reactions between radiation and living tissue, are not exactly unfamiliar and yet, for most of us, they are not comfortable areas of expertise: in that we have some basic knowledge but not enough to draw conclusions and interpret. In particular, it is not easy to answer the very sensible questions that patients ask, when being considered for this particular form of treatment. The author has attempted to describe the basic relevant phenomenology in terms that should be readily understandable to a non-specialist physician. To do this, he has been heavily dependent on the expertise of a number of mathematically sophisticated collaborators, who have checked his manuscript. They are named in the acknowledgments section. The relevance of the different sections of this book will naturally be assessed differently, according to the experience and interest of the reader. To simplifY access to the information that is required, the book is divided into three main sections. 232 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Es war mir sehr willkommen, dag mir der Springer-Verlag angeboten hat, eine Neuauflage dieses Hingst vergriffenen Buches zu bringen. Denn es waren an ihm wesentliche Verbesserungen und Erganzungen notwendig, die ich nun in einer eingreifenden Neubearbeitung gege ben habe. Das Buch ist zum gr6geren Teil neu geschrieben. Ich habe mich bemuht, die in der ersten Auflage fehlende Literatur nach zutragen. Fur die Literatur zur Anwendung der Arithmetik in der Naturwissenschaft kann ich auf das ungemein reiche Literatur verzeichnis bei BR. ELLIS, Basic Concepts of Measurement, 1966, S.207-215, verweisen. Gleichwohl finden die letzten Grundlagen der Anwendung sowohl der Mathematik wie der Logik nicht das gebuhrende Interesse. Ich bin Herrn Kollegen Professor B. JUHOS fur die Durchsicht des mathematischen Teiles sehr zu Dank verpflichtet und auch Herrn Dr. R. HINK yom Springer-Verlag fur die groge Miihe, die er sich mit der Herrichtung des Manuskriptes fur den Druck gegeben hat. Wie meine 'Erkenntnislehre' zu meinem 80. Geburtstag k6nnte ich diese Neubearbeitung als Festgabe zu meinem 90. nehmen. Hoffentlich errege ich damit aber nicht ein Vorurteil gegen sie. 120 pp. Deutsch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Es ist schon lange bekannt, daB Kurbelwellenbriiche der Verbrennungskraftmaschine in der Regel Dauerbriiche sind, sofern sie nicht als Folgen von Lagerschaden auftreten. Die Dauer briiche werden durch Biege- und Torsionswechselbeanspruchungen hervorgerufen, die zu einer tiberschreitung der vom Material dauernd ertragbaren Beanspruchung fiihren. Deshalb sind die Ermittlung und die Begrenzung der dynamischen Beanspruchung des Motortriebwerks ein schwin gungstechnisches Problem von permanenter Aktualitat, das bei jeder Entwicklung eines neuen Motors immer wieder gelOst werden muB. Mit der Losung dieses Problems beschaftigen sich Ingenieure schon seit mehr als 60 Jahren, und neue Impulse, sich mit der Dynamik des Motor triebwerks zu beschaftigen, lOsen in letzter Zeit die gesetzlichen Forderungen nach dem um weltfreundlichen und gerauscharmen Motor aus. Sowohl die Festigkeitsprobleme als auch das Problem, die Korper- und Luftschallemission des Motors zu reduzieren, sind ohne Grundkennt nisse der Schwingungslehre nicht lOsbar. Der vorliegende Band 3 in der Neuen Folge der von H. LIST und A. PISCHINGER herausgegebe nen Buchreihe 'Die Verbrennungskraftmaschine' befaBt sich mit den Grundlagen der mechani schen Schwingungen, deren Kenntnisse erforderlich sind, urn das Entstehen und die Wirkungs weise der Triebwerksschwingungen verstehen zu konnen. Die Torsionsschwingungen der Kurbel welle, das bedeutendste Schwingungsproblem des Motortriebwerks, werden im Band 4 dieser Buchreihe behandelt. Ein GroBteil der dort verwendeten Bewegungsgleichungen, Algorithmen und FORTRAN-Programme wird bereits in diesem Band entwickelt. Trotz dieser speziellen Thematik kann der Band 3 auch als Einfiihrung in die Schwingungsprobleme des Maschinenbaus verwendet werden. 228 pp. Deutsch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Die SCHWARTzschen Distributionen, mit deren Hilfe eine Legalisierung idealisierter Begriffe wie Punktladung, Punktmasse, Einzelkraft, Linienkraft usw. sowie damit in Verbindung stehender Rechenoperationen erreicht wurde, kann man heute zum mathematischen Allgemeingut rechnen. Fur die Theorie und Anwendung der Distributionen und Operatoren gibt es hervorragende Bucher in deutscher Sprache, wie etwa die von BERG [2], GELFAND und SCHILOW [8], MIKUSINSKI [16] und WLADIMIROW [26]. Trotzdem wird auch heute noch vielfach empirisch mit den oben genannten physi kalischen GroBen gearbeitet, und die Kenntnis der exakten mathematischen Theorien ist auf einen relativ kleinen Kreis von Anwendern beschrankt. Das Anliegen des vorIiegenden Buches besteht darin, die genannte Theorie in einer Weise darzubieten, daB ein sehr breiter Leserkreis angesprochen wird. Es entstand auf der Grundlage von Vorlesungen, die die Autoren vor interessierten Mitarbeitern vor aHem technischer Wissenschaftsdisziplinen gehalten haben, und stiitzt sich auf die oben genannten Lehrbucher. Beweise, die tiefere mathematische Kenntnisse voraussetzen, wurden weggelassen. In vielen Fallen kann sich der Leser mit den Kenntnissen aus Fachschullehrbuchern ([1] und [15]) an die dargebotenen Zu sammenhiinge herantasten. Das Buch ist so aufgebaut, daB er sich mit der einfachsten Einfuhrung der Distributionen als eindimensionale Theorie ausfuhrIich vertraut machen kann. Durch entsprechende Erlauterungen und Bilder wird versucht, den Stoff so anschauIich wie nur moglich zu vermitteln und eine rezeptartige Anwendung zu ermoglichen. Die Beispiele wurden so ausgewahlt, daB man direkte Anwendungs moglichkeiten in der Praxis erkennen kann. Die mehrdimensionale Theorie, die gewiB nur einen kleineren Leserkreis interessiert, ist zur Information im Anhang kurz dargeboten. 284 pp. Deutsch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Als urn die Mitte des vorigen Jahrhunderts die Wettervorhersage durch Ein fUhrung der synoptischen Wetterkarte auf eine erfolgversprechende Grundlage gestellt wurde, sah sich die meteorologische Wissenschaft mit einer groBen Anzahl von Problemen konfrontiert, die es zu bewaltigen galt. Reute, rund hundert Jahre spater, konnen wir feststellen, daB viele der erwachsenen Aufgaben gelost werden konnten, daB aber viele noch der Losung harren. Dabei reicht das Spektrum der anstehenden Probleme von rein organisatorischen Fragen (Errichtung und MeB Betreuung des synoptischen Beobachtungsnetzes) iiber Methoden der technik bis zu wissenschaftlich-theoretischen Untersuchungen, die als Grundlage der Wetterprognose dienen. Das vorliegende Buch befaBt sich nur mit dem letztgenannten Fragenkomplex. Der Wetterablauf wird als physikalischer ProzeB betrachtet, der sich aus einem Anfangszustand - dargestellt durch eine mit hinreichend vielen Wetterbeobach tungen ausgestattete Wetterkarte - zu einem Endzustand entwickelt, den es mit theoretischen oder empirischen Methoden vorauszusagen gilt. Der physika lische Endzustand ist durch die (prognostizierte) Feldverteilung verschiedener meteorologischer Elemente gegeben. Die sprachliche Formulierung der Wettervor hersage stellt eine Interpretation solcher Vorhersagekarten dar. Bei dieser Vor gangsweise solI ein Maximum an Objektivitat erreicht werden. 232 pp. Deutsch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The take-over of the philosophy of mathematics by mathematical logic is not complete. The central problems examined in this book lie in the fringe area between the two, and by their very nature will no doubt continue to fall partly within the philosophical re mainder. In seeking to treat these problems with a properly sober mixture of rhyme and reason, I have tried to keep philosophical jargon to a minimum and to avoid excessive mathematical compli cation. The reader with a philosophical background should be familiar with the formal syntactico-semantical explications of proof and truth, especially if he wishes to linger on Chapter 1, after which it is easier philosophical sailing; while the mathematician need only know that to 'explicate' a concept consists in clarifying a heretofore vague notion by proposing a clearer (sometimes formal) definition or formulation for it. More seriously, the interested mathematician will find occasional recourse to EDWARD'S Encyclopedia of Philos ophy (cf. bibliography) highly rewarding. Sections 2. 5 and 2. 7 are of interest mainly to philosophers. The bibliography only contains works referred to in the text. References are made by giving the author's surname followed by the year of publication, the latter enclosed in parentheses. When the author referred to is obvious from the context, the surname is dropped, and even the year of publication or 'ibid. ' may be dropped when the same publication is referred to exclusively over the course of several paragraphs. 176 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Biologists ask how the growth, development and behaviour of organisms happen, how these processes are co-ordinated and how they are regulated by the environment. Today the questions are phrased in terms of the genes involved, their structure and the control of their expression. Mutations (recognised by a change in phenotype) label genes and can be used to study gene structure, gene function and the organisation of the genome. This is 'Genetics'. Study of phenotypes down to the level of the enzymes and structural proteins coded for by genes is 'Biochemistry'. It is self evident that only by studying phenotype ('Biochemistry') can we do 'Ge netics' and that 'Genetics' (perturbation of the phenotype) is the key to understanding the 'Biochemistry'. There can surely be no better argu ments for a more holistic approach to biology than the massive output of knowledge from microbial 'Biochemical Genetics' and the more recent revelations from 'Molecular Genetic' studies of development in Droso phila. 312 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -There has been recent rapid progress in the transformation of plants with foreign DNA, making use either of the natural routes of genetic invasion that viruses and bacteria have developed, or of chemical, mechanical and electrical tricks to make plant protoplast membranes permeable to nucleic acids. Genes integrated into plant virus genomes can be carried systemi cally from the initial site of infection into the rest of the plant. Genes placed between the borders of Agrobacterium tumefaciens T-DNA can be transferred into single cells or plant tissue, which then divides to produce wound calli, or as in the case of an Agrobacterium rhizogenes infection, grow out into new roots. Calli and roots can be grown into whole plants. If virus genomes are placed between the T-DNA borders, a very effective infectious route, termed 'agroinfection', is established. Once inside a pro toplast, DNA finds its way into the nucleus where it can finally integrate into the resident chromosome and be expressed. Whether it can also find its way into chloroplasts is not yet clear, but at least translation products can be targeted into this organelle. Regeneration of whole organisms from single cells is a special feature of plants and offers a unique tool to study genes in a multicellular organism. In addition, as in animal cells, transcription and translation of trans forming genes can be studied in plant cells during 'transient expression'. 368 pp. Englisch.

Zechmeister, have appeared under the Springer imprint ever since the series was founded in 1938. The volumes contain contributions on various topics related to the origin, distribution, chemistry, synthesis, biochemistry, function or use of various classes of naturally occurring substances ranging from small molecules to biopolymers. Each contribution is written by a recognized authority in his field and provides a comprehensive and up-to-date review of the topic in question. Addressed to biologists, technologists and chemists alike, the series can be used by the expert as a source of information and literature citations and by the non-expert as a means of orientation in a rapidly developing discipline. 332 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -Whereas two-dimensional semiconductor process simulation has achieved a certain degree of maturity, three-dimensional process simulation is a newly emerging field in which most efforts are dedicated to necessary basic developments. Research in this area is promoted by the growing demand to obtain reliable information on device geometries and dopant distributions needed for three-dimensional device simulation, and challenged by the great algorithmic problems caused by moving interfaces and by the requirement to limit computation times and memory requirements. A workshop (Erlangen, September 5, 1995) provided a forum to discuss the industrial needs, technical problems, and solutions being developed in the field of three-dimensional semiconductor process simulation. Invited presentations from leading semiconductor companies and research Centers of Excellence from Japan, the USA, and Europe outlined novel numerical algorithms, physical models, and applications in this rapidly emerging field. 212 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -As an addition to the European postgraduate training system for young neurosurgeons we began to publish in 1974 this series devoted to Advances and Technical Standards in Neurosurgery which was later sponsored by the European Association of Neurosurgical Societies. The fact that the English language is well on the way to becoming the international medium at European scientific conferences is a great asset in terms of mutual understanding. Therefore we have decided to publish all contributions in English, regardless of the native language of the authors. All contributions are submitted to the entire editorial board before publication of any volume. Our series is not intended to compete with the publications of original scientific papers in other neurosurgical journals. Our intention is, rather, to present fields of neurosurgery and related areas in which important recent advances have been made. The contributions are written by specialists in the given fields and constitute the first part of each volume. In the second part of each volume, we publish detailed descriptions of standard operative procedures, furnished by experienced clinicians; in these articles the authors describe the techniques they employ and explain the advantages, difficulties and risks involved in the various procedures. This part is intended primarily to assist young neurosurgeons in their postgraduate training. However, we are convinced that it will also be useful to experienced, fully trained neurosurgeons. 208 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The objective of this ASI was to bring together specialists in several complex variables (many of whom have contributed to complex potential theory) and specialists in potential theory (all of whom have contributed to several complex variables) together with young researchers and graduate students for an interchange of ideas and techniques. Not only was the status of current research presented, but also the relevant background, much of which is not yet available in books. The following topics and interconnections among them were discussed: 1. Real and Complex Potential Theory. Capacity and approximation, basic prop erties of plurisubharmonic functions and methods to manipulate their singularities and study their growth, Green functions, Chebyshev-type quadratures, electrostatic fields and potentials, propagation of smallness. 2. Complex Dynamics. Review of complex dynamics in one variable, Julia sets, Fatou sets, background in several variables, Henon maps, ergodicity, use of potential theory and multifunctions. 3. Banach Algebras and Infinite Dimensional Holomorphy. Analytic multi functions, spectral theory, analytic functions on a Banach space, semigroups of holomor phic isometries, Pick interpolation on uniform algebras and Von Neumann inequalities for operators on a Hilbert space. The basic notion of complex potential theory is that of a plurisubharmonic function. 516 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -Plant growth and development is controlled by various environmental cues that are sensed by the plant via various signal transduction pathways coupled to specific response. Some of these pathways are conserved from yeast to plants being regulated by various kinases and phosphatases. In addition, plants have many unique pathways that transduce to specific signals such as light, phytohormones and oligosaccharides. This volume highlights some of the examples of the plant signal transduction machinery opening new vistas in research on plant growth and development. The new technologies including the use of bacteria, yeast and Arabidopsis as functional complementation systems are providing proof of function of many of the proteins that show homology to those from other organisms. These studies will eventually lead to improvement of crop plants and use of plants as a new resource for producing desirable products to meet the growing needs of mankind. 340 pp. Englisch.

This series was first discussed in 1972 at a combined meeting of the Italian and German Neurosurgical Societies in Taormina, the founding fathers of the series being Jean Brihaye, Bernard Pertuiset, Fritz Loew and Hugo Krayenbiihl. Thus were established the principles of European co operation which have been born from the European spirit, flourished in the European Association, and have throughout been associated with this series.

Sehr viele wis senschaftliche Untersuchungen beschaftigen sich daher mit dieser Erkrankung. In der medizinischen Datenbank MEDLINE finden sich uber 6000 Eintrage unter den Begriffen 'panic' und 'agoraphobia'. In diesem Buch wurde versucht, die groRe Zahl wissenschaftlicher Befunde zu sichten und eine moglichst umfas sende Darstellung des Krankheitsbildes zu erstellen. Welche Rolle spielen fruhkindliche Traumata, elterliches Interaktionsverhalten, Lernerfahrungen, Vererbung und Neurobiologie bei der Entstehung von patholo gischer Angst und Panik In dem vorliegenden Buch wird ein neues neurobiolo gisch-psychosoziales Modell zur Entstehung von Panikattacken und Agoraphobie entwickelt, das versucht, die Vielzahl der teilweise widerspruchlichen Befunde zu diesem Thema zu integrieren. In den letzten Jahren hat es fur die Menschen, die unter Panikattacken und Agoraphobie litten, positive Veranderungen gegeben: das Krankheitsbild wird zunehmend haufiger erkannt, die Hypothesen zu ihrer Entstehung wurden genauer und die Behandlung wurde auf dem Boden wissenschaftlicher Unter suchungen immer weiter verbessert. Mit Hilfe von psychotherapeutischen und medikamentosen MaRnahmen konnte die Lebensqualitat der Patienten entschei dend verbessert werden. Welches sind die optimalen psychotherapeutischen MaRnahmen, welche Rolle spielen Psychopharmaka Welche neuen Behandlungsformen gibt es Mit einem Anspruch auf Vollstandigkeit werden aile verfugbaren kontrollierten Studien zu diesem Thema referiert. Streng den Regeln der 'evidence based medicine' folgend, wird eine Strategie zur Therapie der Panikstorung entwickelt.
