Polyvinylpyrrolidone is widely used in medicine, pharmaceuticals, cosmetics, foods, printing inks, textiles, and many more diverse applications. This book describes the 50 years of research, published and unpublished, on the absorption, distribution, storage, and excretion of PVP. The toxicology of PVP is critically evaluated.The author's involvement in the recent reevaluation of PVP by the Joint Expert Committee on Food Additives of the World Health Organization (WHO) and the Food and Agriculture Organization (FOA) led them to undertake this comprehensive review of all the information on the subject. This book will be invaluable for anyone who is involved with polyvinylpyrrolidone. Included is a broad review of the toxicological studies performed on PVP, including acute, subchronic, chronic, reproductive, mutagenicity, and carcinogenicity studies. There is also an appendix listing the key studies, with references, on the absorption, renal elimination, distribution, acute toxicity, subchronic toxicity, chronic toxicity, teratogenicity, mutagenicity, and carcinogenicity of PVP.

The aim of this book is to characterize certain multiplicative and additive arithmetical functions by combining methods from number theory with some simple ideas from functional and harmonic analysis. The authors achieve this goal by considering convolutions of arithmetical functions, elementary mean-value theorems, and properties of related multiplicative functions. They also prove the mean-value theorems of Wirsing and Halász and study the pointwise convergence of the Ramanujan expansion. Finally, some applications to power series with multiplicative coefficients are included, along with exercises and an extensive bibliography.

Design automation of electronic and hybrid systems is a steadily growing field of interest and a permanent challenge for researchers in electronics, computer engineering and computer science. "System Design Automation" presents results in design automation of different types of electronic and mechatronic systems. It deals with various topics of design automation, ranging from high level digital system synthesis, through analogue and heterogeneous system analysis and design, up to system modelling and simulation. Design automation is treated from the aspects of its theoretical fundamentals, its basic approach and its methods and tools. Several application cases are presented in detail. The book consists of three chapters: high-level system synthesis (digital hardware/software systems), here embedded systems, distributed systems and processor arrays as well as hardware-software codesign are treated. Also three special application cases are discussed in detail; analog and heterogeneous system design (system approach and methodology).This chapter copes with the analysis and design of hybrid systems comprised of analog and digital, electronic and mechanical components; and system simulation and evaluation (methods and tools).In this chapter object-oriented modelling, analog system simulation including fault-simulation, parameter optimization and system validation are regarded. The contents of the book is based on material presented at the Workshop System Design Automation (SDA 2000) organized by the Sonderforschungsbereich 358 of the Deutsche Forschungsgemeinschaft at TU Dresden.

This updated and revised textbook presents a broad overview on topics concerning cellular electrophysiology – ranging from bioelectric phenomena recognized as far back as ancient Egypt to popular topics on the dangers of electrosmog. Without sacrificing scientific precision, this clear and concise work presents on the one hand the different methods and modern applications, on the other hand the biophysical fundamentals of ion-channel and carrier proteins. Numerous and carefully selected illustrations and diagrams supplement the text. Each chapter is extended by a detailed table of Take-Home Messages. Questions at the end of each chapter allow readers to test their understanding. Each section also includes references to relevant original literature for further reading. The book offers a valuable resource for students of biology, chemistry and physics with a special interest in biophysics.

Dieses Lehrbuch bietet einen umfassenden Überblick zur zellulären Elektrophysiologie. Die Themen reichen von bioelektrischen Phänomenen, die schon im antiken Ägypten beschrieben wurden, bis hin zu aktuellen Streitfragen wie der Gefahr durch Elektrosmog. Dieses kurz und prägnant geschriebene Werk beschreibt wissenschaftlich präzise verschiedene Methoden und Anwendungen der Elektrophysiologie sowie die biophysiologischen Grundlagen von Ionenkanälen und Carrier-Proteinen. Zahlreiche sorgsam ausgewählte Illustrationen und Grafiken ergänzen das Geschriebene, während Fragen am Ende jedes Kapitels dem Leser die Möglichkeit zur Selbstkontrolle bieten. Jeder Abschnitt enthält zudem Verweise auf relevante Publikationen und Literaturstellen, die für ein tieferes Verständnis zu Rate gezogen werden können. Das Buch stellt somit eine wertvolle Informationsquelle für Studierende der Biologie, Chemie und Physik dar, die sich speziell für Biophysik interessieren.

Erinnern Sie sich an eine Alltagssituation, in der es Ihnen gelungen ist, aus einem Problem eine Aufgabe zu machen, die Sie erfolgreich bewältigen konnten? Und haben Sie dabei vom Einsatz geeigneter Werkzeuge profitiert?Solche Szenarien prägen den beruflichen Alltag aller Studierenden mathematischer Fachrichtungen. Man sieht sich permanent mit mathematischen Problemen konfrontiert, zu deren Lösung es einer guten Idee bedarf; oft findet man diese aber nicht, weil man sich der Werkzeuge nicht bewusst ist, mit denen man die Lösungsidee freilegen kann.Dieses Buch soll hier Abhilfe schaffen. Anhand von ca. 70 Beispielen aus der Diskreten Mathematik, der Arithmetik, der Zahlentheorie, der Stochastik, der Geometrie, der Linearen Algebra, der reellen Analysis, der Funktionentheorie, der Kombinatorik und der Mathematikgeschichte wird eine umfangreiche Auswahl heuristischer Vorgehensweisen erläutert, denen die Rolle des Werkzeugs in Problemlöseprozessen zufällt.Die heuristischen Strategien des Problemlösens werden strukturell systematisiert und nach Möglichkeit prozessual den verschiedenen Phasen des Problemlöseprozesses nach Pólya zugeordnet; dadurch entsteht nicht nur Ordnung im heuristischen Werkzeugkasten, sondern auch eine Verfeinerung des Pólya'schen Phasenmodells des Problemlösens.

„Problemlösen durch Mathematik? Mathematik ist doch das Problem …“Dass Mathematik als sinnfällig und nachvollziehbar, als ein praktisches Instrument zur Erreichung der eigenen Ziele erlebt wird, stellt in der Bildungsbiographie eine Ausnahme dar. Tatsächlich ist Mathematik wohl das unbeliebteste und ‚schwierigste‘ Fach in der Schule – und oft kommt vorwurfsvoll die Frage hinzu: Wozu brauche ich das überhaupt?Die Situation ist dabei weder Zufall noch schicksalhaft, sondern Folge einer verfehlten Didaktik. Nur ein Neudenken schulischen Unterrichts und eine gründliche Rückbesinnung auf das, was Mathematik ihrem Wesen und Ursprung nach ist, wird für Lernende wie Unterrichtende den lange schwelenden Konflikt auflösen und endlich Wege für alle in die Welt der Mathematik weisen können. Und dabei kann die Heuristik der Schlüssel sein.
