Taschenbuch. Etat : Neu. 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.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 236 pp. Englisch.

Buch. Etat : Neu. Neuware -The present text aims at helping the reader to maximize the reuse of information. Topics covered include tools and services for creating simple, rich, and reusable knowledge representations to explore strategies for integrating this knowledge into legacy systems. The reuse and integration are essential concepts that must be enforced to avoid duplicating the effort and reinventing the wheel each time in the same field. This problem is investigated from different perspectives. in organizations, high volumes of data from different sources form a big threat for filtering out the information for effective decision making. the reader will be informed of the most recent advances in information reuse and integration.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 416 pp. Englisch.

Taschenbuch. Etat : Neu. Neuware -The decision of Harvey Cushing to leave general surgery and concentrate on the infant field of central nervous system surgery was in retrospect a landmark in the history of neurosurgery. His concentrated work, and also that of his colleague Walter Dandy, originated with the desires of both pioneers to understand surgical anatomy and neurophysiology. The fundamental knowledge and surgical techni ques that they provided became the standard of excellence for several generations of neurosurgeons; so much so that the general belief was that the surgical techniques could not be improved upon. Twenty-five to thirty years ago microtechniques began to appear in a few surgical research centers, they were then gradually applied to clinical neurosurgery and have contributed to a new level of understanding in surgical anatomy and neurophysiology. We are now fortunate to have a new standard of morbidity and mortality in the surgical treatment of intrathecal aneurysms, angiomas, and tumors. It has been said that microneurosurgery was reaching its limits, especially when treating lesions in and around the cavernous sinus and skull base; those lesions notorious for involvement of the dural and extradural compartments, with a tendency to infiltrate adjacent nerves and blood vessels. The dangers of uncontrollable hemorrhage from the basal sinuses and post-operative CSF rhinorrhea appeared unsurmountable. The lateral aspects of the petro-clival region have been of interest to a few pioneering ENT surgeons and neurosurgeons but the cavernous sinus in most respects has remained the final unconquered summit.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 360 pp. Englisch.

Taschenbuch. Etat : Neu. Neuware -Oft wird nur jenes anerkannt, was 'wissenschaftlich beweisbar' ist. 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. Etat : Neu. 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.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 228 pp. Deutsch.

Taschenbuch. Etat : Neu. 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.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 232 pp. Deutsch.

Taschenbuch. Etat : Neu. Neuware -Dieses Werk ist das erste umfassende deutschsprachige Handbuch über Diabetes und Schwangerschaft und den zugehörigen physiologischen und pathophysiologischen Besonderheiten des Stoffwechsels. Das Buch stützt sich auf langjährige Erfahrungen, da Diabetes und Schwangerschaft an der Grazer Frauenklinik seit mehr als 25 Jahren ein permanenter Forschungsschwerpunkt ist. Die klinischen Erfahrungen beruhen auf ca. 1400 insulinbehandelten und rund 1200 diätbehandelten Diabetikerinnen. Neben den Forschungsarbeiten der Klinik haben zahlreiche Publikationen der internationalen Fachliteratur in die verschiedenen Kapitel Eingang gefunden.Im Buch werden gleichermaßen die klinische Routine, klinische Probleme und Forschungsbereiche behandelt. Es ist als Nachschlagwerk für alle jene gedacht, die in der Praxis, am Krankenbett oder in der Forschung mit Diabetes und Schwangerschaft befasst sind und damit auch mit ausgefallenen Fragen konfrontiert werden.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 848 pp. Deutsch.

Taschenbuch. Etat : Neu. Neuware -VI Dagegen kann in diesem Rahmen auf eine ausführliche Darstellung von Bau und Aussehen des Kehlkopfes, seiner Muskeln, Nerven und Gefäße oder der übri gen Sprechorgane verzichtet werden. Es dürften durchwegs einige anatomische Vorbemerkungen genügen, um die Verbindung mit den entsprechenden Lehr büchern der Anatomie oder Laryngologie herzustellen. Um so wichtiger war jedoch die Mitarbeit von Prof. Dr. phi! FRIEDRICH KAINZ und Dr. phi! EDELTRuD BAAR in den psychologischen Kapiteln. Zahlreiche phoniatrische Arbeiten befaßten sich in den letzten Jahren damit, die bislang gewonnenen experimental-phonetischen Erkenntnisse durch röntgeno logische und klanganalytische Untersuchungen zu überprüfen und zu ergänzen. Mit Hilfe der neuen Geräte zur elektrischen Klanganalyse gelingt es denn auch, das Problem der phonischen Leistungen des Kehlkopfes weiter zu klären. Ebenso verspricht die moderne, durch die Röhrentechnik weitgehend verbesserte Strobo skopie genauere Einblicke in den schwer enthüllbaren Mechanismus des Stimm organes. Zu diesem großen Aufgabenkreis ist zuletzt noch die Erbbiologie getreten. Neben bedeutsamen theoretischen Ergebnissen erlaubt sie auch, praktische Schluß folgerungen zu ziehen. Spielt doch die erbliche Herkunft der Stimme, die Form und Größe des Kehlkopfes oder die Konstitution der Schleimhaut, z. B. für den Sänger, eine lebenswichtige Rolle. Zwar sieht es so aus, als ob die sinnvolle Methodik unserer Arbeitsweise weit gehend spezialisiert sei; sie führt aber immer wieder zur Gesamtmedizin zurück. Man denke bloß an den untrennbaren Zusammenhang der Atmung mit den Stimmstörungen, an die pathognomonisch wichtigen oder lebensbedrohenden Kehlkopflähmungen oder an die endokrin bedingten Veränderungen der Stimme.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 504 pp. Deutsch.

Taschenbuch. Etat : Neu. Gratzer, J.; Schimek, H. (illustrateur). Neuware -1,9 Millionen Deutsche sind vom Morbus Dupuytren betroffen. Eine Rezidivrate von über 50% nach chirurgischen Therapieversuchen zeigt, dass die Erkrankung nicht ausschließlich chirurgisch behandelbar ist. In diesem Werk werden daher zwei Wege eingeschlagen: Einerseits wird durch eine Beschreibung der biochemischen und molekularbiologischen Veränderungen des erkrankten Bindegewebes der systemische Charakter des Morbus Dupuytren im Kontext mit anderen Bindegewebserkrankungen hervorgehoben. Andererseits werden die unterschiedlichen therapeutischen Ansätze aus einer differenzierten Darstellung der anatomischen Gegebenheiten hergeleitet. Neben den Grundzügen konservativer Therapie werden alle gängigen chirurgischen Verfahren inklusive verfahrensspezifischer Komplikationen beschrieben sowie zeichnerisch in ihren wesentlichen Zügen vorgestellt. Das Buch wendet sich an alle, die eine aktuelle Übersicht zum Morbus Dupuytren wünschen und über die etablierten Therapiekonzepte instruktiv unterrichtet werden wollen.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 260 pp. Deutsch.

Taschenbuch. Etat : Neu. 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. Etat : 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. Etat : 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. Etat : 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.
