Concepts of nonlinear physics are applied to an increasing number of research disciplines. With this volume, the editors offer a selection of articles on nonlinear topics in progress, ranging from physics and chemistry to biology and some applications of social science. The book covers quantum optics, electron crystallization, cellular or flow patterns in fluids and in granular media, biological systems, and the control of brain structures via neuronal excitation. Chemical patterns are looked at both in bulk solutions and on surfaces in heterogeneous systems. From regular structures, the authors turn to the more complex behavior in biology and physics, such as hydrodynamical turbulence, low-dimensional dynamics in solid-state physics, and gravity.

Current biological research demands the extensive use of sophisticated mathematical methods and computer-aided analysis of experiments and data. This highly interdisciplinary volume focuses on structural, dynamical and functional aspects of cellular systems and presents corresponding experiments and mathematical models. The book may serve as an introduction for biologists, mathematicians and physicists to key questions in cellular systems which can be studied with mathematical models. Recent model approaches are presented with applications in cellular metabolism, intra- and intercellular signaling, cellular mechanics, network dynamics and pattern formation. In addition, applied issues such as tumor cell growth, dynamics of the immune system and biotechnology are included.

Local and global spatial coupling mechanisms form the basis of transport processes that are of fundamental importance for the occurrence and the dynamic evolution of patterns on a mesoscopic and macroscopic scale. The present volume deals with these concepts and investigates applications in the fields of biophysics and chemistry.

The review articles in this book treat the overall nonlinear and complex behavior of nature from the viewpoint of such diverse research fields as fluid mechanics, condensed matter physics, biophysics, biochemistry, biology, and applied mathematics. Attention is focussed on a broad and comprehensive overview of recent developments and perspectives. Particular attention is given to the so-far unsolved problem of how to capture the mutual interplay between the microscopic and macroscopic dynamics that extend over various length and time scales. The book addresses researchers as well as graduate students.

Von Prof. Dr. HEINRICH MARTIUS, Goettingen. Die Ausbildung der Hebammen krankt heute ebenso wie die der meisten anderen praktischen Berufe an einem vollstandigen Mangel an Lehrbuchern. Bei den Schulerinnen gehen die wenigen noch vorhandenen Exemplare in den knappen Freistunden, die sie neben der praktischen Ausbildung und den Vortragen ihrer Lehrer zum Nachlesen und Lernen zur Verfugung haben, von Hand zu Hand. Vielen schon im Beruf stehenden Hebammen fehlt es uberhaupt an einem Lehrbuch, oder sie mussen sich, wenn sie etwas nachschlagen wollen, mit einer veralteten Auflage begnugen. In Anbetracht dieser Notlage sind wir der Aufforderung des Verlages b.: reitwillig nachgekommen, das alte; Preussische Heb- ammenlehrbuch", das sich stets hoher Wertschatzung erfreute, fur eine neue Auflage vorzubereiten. Das "Preussische Hebammenlehrbuch" ist schon einmal aus der Goettinger Frauenklinik hervorgegangen. Im Jahre 1903 uber- trug der Koeniglich Preussische Minister des Innern die Bearbeitung desselben dem Direktor der Universitats-Frauenklinik in Goettingen, Prof.Dr. MAX RUNGE. Der Entwurf wurde sodann in einer Kommission beraten und der definitive Wortlaut in der Medizinal- abteilung des Ministeriums festgestellt. Bei der Abfassung des Lehrbuches wurde damals schon die Absicht verfolgt, "allmahlich besser vorgebildete Elemente dem Hebammenstande zuzufuhren, ohne dass eine Erweiterung der Befugnisse stattfinden durfe", eine Forderung, die auch heute noch die unsere ist. Das Buch erschien dann in mehreren Auflagen rasch hintereinander. In- zwischen hatte es sich als notwendig erwiesen, wieder eine voll- standige Umarbeitung vorzunehmen, mit der von dem Ministerium fur Volkswohlfahrt folgende Autoren beauftragt wurden: Prof.
