This volume is based on lectures given at the NATO-Advanced Study Institute on Structure and Dynamics of Polymer and Colloid Systems held in Les Houches, France from September 14-24, 1999. The meeting arose from a perceived need to bring together scientists studying the polymer and colloid fields. Although these fields are intertwined and share many techniques (e. g. , light, neutron and x-ray scattering), it is remarkable how little the approaches and concepts used by the one field penetrate the other. For instance, the theory of spherical colloids is very highly developed and many of the concepts developed for these systems can be extended to those with non-spherical morphology, such as solutions of rigid rod polymers. In addition, mixtures of polymers and colloids, both in the bulk and at interfaces, are the basis for many industrial products. Methods are now rapidly being developed for understanding the structure and dynamics in polymer/colloid mixtures at the molecular level, but the point of view of the colloid scientist is often rather different from that of the polymer scientist. The NATO-ASI brought together polymer and colloid scientists, including many young researchers, who presented and discussed recent developments in these fields and the possibilities for cross-fertilization This volume contains articles on a wide variety of topics at the research forefront of the polymer and colloid fields by some of the world's foremost experts at a level accessible to graduate students, post-docs and researchers.

This book, now in its third edition, explores how human populations grow, based on their creative abilities. To reconsider the theory of economic growth from a physicist's perspective, the book analyses the concepts of value and utility and their relationship to thermodynamic concepts. This approach allows the author to include characteristics of technology in descriptions of development and to formulate a phenomenological (macroeconomic, no-price fluctuations are discussed) theory of production as a set of evolutionary equations in one-sector and multi-sector approximations. The theory is proved to be useful for describing both national economies and global production in ancient times. This monograph presents the topics in a compact and consistent manner and can be used by students with a background in physics and other natural sciences who wish to specialize in economics. It explains how the growth of production is connected with advances in technology, consumption of labour and energy and makes it possible to analyse past and present social production systems and to build scripts of future progress. The book is of interest to energy specialists engaged in planning and analyzing the production and consumption of energy carriers, and to economists wanting to know how energy and technology affect economic growth. This third edition has been substantially revised and three brand new chapters have been added. Chapter 8 illustrates the robustness of the theory with the aid of statistical historical data from the Russian economy, while Chapter 12 is devoted to a reconstruction of the global production activity in ancient times. Chapter 13 discusses the principles of the organization of social production.

Polymers are essential to biology because they can have enough stable degrees of freedom to store the molecular code of heredity and to express the sequences needed to manufacture new molecules. Through these they perform or control virtually every function in life. Although some biopolymers are created and spend their entire career in the relatively large free space inside cells or organelles, many biopolymers must migrate through a narrow passageway to get to their targeted destination. This suggests the questions: How does confining a polymer affect its behavior and function? What does that tell us about the interactions between the monomers that comprise the polymer and the molecules that confine it? Can we design and build devices that mimic the functions of these nanoscale systems? The NATO Advanced Research Workshop brought together for four days in Bikal, Hungary over forty experts in experimental and theoretical biophysics, molecular biology, biophysical chemistry, and biochemistry interested in these questions. Their papers collected in this book provide insight on biological processes involving confinement and form a basis for new biotechnological applications using polymers. In his paper Edmund DiMarzio asks: What is so special about polymers? Why are polymers so prevalent in living things? The chemist says the reason is that a protein made of N amino acids can have any of 20 different kinds at each position along the chain, resulting in 20 N different polymers, and that the complexity of life lies in this variety.

Provides the basic background needed by engineers to determine experimentally and interpret the rheological behavior of polymer melts--including not only traditional pure melts but also solutions and compounds containing anisotropic (fiber or disc) or colloidal particles--and apply it to analyze flow in processing operations. Experimental foundations of modern rheology and rheo-optics and the interpretation of experimental data are covered, which also develops the fundamentals of continuum mechanics and shows how it may be applied to devise methods for measurement of rheological properties, formulation of three-dimensional stress-deformation relationships, and analysis of flow in processing operations. Also discusses the structure of polymers and considers rheological behavior in terms of structure. Constitutive equations relating stress to deformation history in non-Newtonian fluids and their applications are discussed. Each chapter presents an overview of the subject matter and then develops the material in a pedagogical manner.

This book covers in great detail the Rouse-segment-based molecular theories in polymer viscoelasticity ? the Rouse theory and the extended reptation theory (based on the framework of the Doi?Edwards theory) ? that have been shown to explain experimental results in a consistently quantitative way. The explanation for the 3.4 power law of viscosity, quantitative line-shape analyses of viscoelastic responses and agreements between different sorts of viscoelastic responses, the consistency between the viscoelasticity and diffusion results, the clarification of the onset of entangelement, the discovery of the number of entanglement strands per cubed entanglement distance being a universal constant and the basic mechanism of the glass transition-related thermorheological complexity are discussed or shown in great detail. The mystery behind the success of the Rouse-segment-based molecular theories over the entropic region of a viscoelastic response is revealed by the Monte Carlo simulations on the Fraenkel chains. Specifically, the simulation studies give a natural explanation for the coexistence of the energy-driven and entropy-driven modes in a viscoelastic response and provide a theoretical basis resolving the paradox that the experimentally determined sizes of Rouse and Kuhn segments are nearly the same. This book starts from a very fundamental level; each chapter is built upon the contents of the previous chapters. Thus, the readers may use the book as a textbook and eventually reach an advanced research level. This book is also a useful source of reference for physicists, chemists and material scientists.

Die Grundlagen und Methoden, die zur theoretischen Modellierung und zur Analyse von Strömungsvorgängen mit nicht-newtonschen Fluiden erforderlich sind, werden in diesem Lehrbuch vorgestellt. Zunächst werden die kinematischen, die kontinuumsmechanischen und die stofflichen Grundlagen ausführlich erläutert. Die Anwendung des Basiswissens erfolgt exemplarisch anhand ausgewählter Strömungsvorgänge, die maßgeblich von den nichtlinearen Fließeigenschaften, von den Normalspannungsdifferenzen oder vom Gedächtnis der Flüssigkeiten beeinflusst werden. Dabei haben sich die Inhalte, die Schwerpunkte und die Beispiele gegenüber der ersten Auflage wesentlich geändert. Erstmalig in einem deutschsprachigen Lehrbuch werden auch die Grundzüge einer numerischen Strömungssimulation unter Berücksichtigung komplexer rheologischer Stoffmodelle behandelt.

may never overcome the effects of hysteresis and stress (see Chapters 6 and 12). The first sentence of the reference work, Handbook of Liquid Crystals, reads: The terms liquid crystals, crystalline liquid, mesophase, and mesomorphous state are used synonymously to describe a state of aggregation that exhibits a molecular order in a size range similar to that of a crystal but acts more or less as a viscous liquid: [2] In other words, molecules within a liquid crystalline phase possess some orientational order and lack positional order; furthermore, the shape of a liquid crystalline sample is determined by the vessel in which it is contained rather than by the orientational order of its aggregated molecules. The authors recognized the limitations and imprecision of this definition but, like others preceding them, could not devise a simple and generally applicable one that is better. Regardless, the terms 'liquid crystal' and 'mesophase' should not be used interchangeably. As mentioned above, all liquid crystals are mesophases, but all mesophases are not liquid crystals. Recent studies, employing elaborate and sophisticated analytical techniques, have permitted finer distinctions between classical crystals and mesophases. At the same time, they have made definitions like that from the Handbook of Liquid Crystals somewhat obsolete for reasons other than terminology. One part of the problem arises from the use of a combination of bulk properties (like flow) and microscopic properties (like molecular ordering) within the same definition.

Die Mechanikvorlesung als zumeist erste Berührung mit der Theoretischen Physik hat in der Grundausbildung besonderes Gewicht. Zum einen führt sie in die klassischen Konzepte der Physik des 18. und 19. Jahrhunderts ein, zum anderen zeigt sie deren Lei- stungsfähigkeit und Bedeutung für die moderne Physik. Das vorliegende Buch geht diesen Weg von der Newtonschen Mechanik bis hin zu modernen Fragestellungen der qualitativen und nichtlinearen Dynamik. Begleitet von einfachen, PC-gestützten Beispielen und in einer Darstellung, die den mehr physikalischen Zugang zur Mechanik mit ihren mathematischen Grundlagen verbindet, beginnt das Buch mit der Newtonschen Mechanik, die bis hin zur Streutheorie und dem Virialproblem geführt wird (Kap.1). Es behandelt die kanonische Mechanik in Lagrangescher und Hamilton-Jakobischer Form, unter Einschluß der symplektischen Struktur des Phasenraums und der Elemente der Störungstheorie (Kap.2). Die Theorie des Starren Körpers (Kap.3) wird ebenso entwickelt wie die Grundlagen der speziellen Relativitätstheorie (Kap.4). Kapitel 5 über die geometrischen Aspekte der Mechanik behandelt ihre mathematisch-geometrischen Grundlagen und schlägt die Brücke zur modernen mechanischen Fachliteratur. Kapitel 6 definiert und illustriert die für das Studium nichtlinearer Dynamik und qualitativer Mechanik wesentlichen Begriffe und diskutiert qualitativ und quantitativ wichtige Beispiele für deterministisches Chaos. Das abschließende Kapitel 7 gibt eine kurze Einführung in kontinuierliche Systeme. Das Buch eignet sich als Begleittext zu den Vorlesungen Einführung in die Theoretische Physik, Allgemeine Mechanik, sowie weiterführende Veranstaltungen und zum Ergänzungs- und Selbststudium.
