Modern polymer materials are designed by applying principles of correlation between chemical structure, physical macrostructure and technological properties. Fundamentals of polymer physics are explained in this book without excessive use of calculations. Four main sections treat relaxation of polymers, melting and crystallization, the mechanism of deformation in thermoplastics, elastomers and multiphase systems, and thermodynamics of mixing and swelling of polymers and polymer networks. The book presents the theoretical models of polymer physics in a comprehensive style and relates their applicability to real polymer systems in terms of the available experimental observations.

Pedagogical Cases in Physical Education and Youth Sport is a completely new kind of resource for students and practitioners working in physical education or youth sport. The book consists of 20 richly described cases of individual young learners, each written by a team of authors with diverse expertise from across the sport, exercise and movement sciences. These cases bring together knowledge from single sub-disciplines into new interdisciplinary knowledge to inform best practice in physical education, teaching and coaching in youth sport settings. At the heart of each case is an individual young person of a specified age and gender, with a range of physical, social and psychological characteristics. Drawing on current research, theory and empirical data from their own specialist discipline, each chapter author identifies the key factors they feel should be taken into account when attempting to teach or coach the young person described. These strands are then drawn together at the end of each chapter and linked to current research from the sport pedagogy literature, to highlight the implications for planning and evaluating teaching or coaching sessions. No other book offers such a rich, vivid and thought-provoking set of pedagogical tools for understanding and working with children and young people in sport. This is an essential resource for any student on a physical education, coaching, kinesiology or sport science course, and for any teacher, coach or instructor working in physical education or youth sport.

Plastics are used worldwide in everyday life, e.g. as food packaging, electronics, construction, automotive parts, and household appliances. To produce these products with the desired service lifetimes the use of suitable stabilizers is necessary. This book provides a concise and comprehensive overview of the basic mechanisms of plastic degradation processes caused by heat and light. At its core is a detailed description of the stabilization of different polymers, including an explanation of stabilization mechanisms and the influence of commonly used additives such as fillers, flame retardents and pigments on the stability of plastic. Every polymer scientist, material technologist, or application engineer dealing with the design of the properties of plastics will benefit from this new overview.

The fourth Nishinomiya-Yukawa Memorial Symposium, devoted to the topic of dynamics and patterns in complex fluids, was held on October 26 and 27, 1989, in Nishinomiya City, Japan, where ten invited speakers gave their lectures. A one-day meeting, comprising short talks and poster sessions, was then held on the same topic on October 28 at the Research Institute for Fundamental Physics, Kyoto University. The present volume contains the 10 invited papers and 38 contributed papers presented at these two meetings. The symposium was sponsored by Nishinomiya City, where Prof. Hideki Yukawa once lived and where he wrote the celebrated paper describing the work that was later honored by a Nobel prize. The topic of the fourth symposium was chosen from one of the most vigorously evolving and highly interdisciplinary fields in condensed matter physics. The field of complex fluids is very diverse and still in its infancy and, as a result, the definition of a complex fluid varies greatly from one researcher to the next. One of the objectives of the symposium was to clarify its definition by explicitly posing a number of potentially rich problems waiting to be explored. Indeed, experimentalists are disclosing a variety of intriguing dynamical phenomena in complex systems such as polymers, liquid crystals, gels, colloids, and surfactant systems. We, the organizers, hope that the symposium will contribute to the increasing importance of the field in the coming years.

This volume contains the proceedings of the first ISSP International Symposium on the Physics and Chemistry of Organic Superconductors, which was held at the Komaba Eminence Hotel in Tokyo, August 28-30, 1989. This symposium was attended by 205 scientists from 12 countries. In total 106 papers were presented: 61 as posters, and 39 original papers and 6 review papers in oral sessions. Of these, 102 papers are included in these proceedings. These contributions cover the interdisciplinary field of physics and chemistry of organic superconductors with particular emphasis on the following subjects and materials: - superconducting properties, - spin density waves, - electronic and structural properties, - TMTSF salts and their derivatives, - BEDT -TTF salts and their derivatives, - metal coordinated organic conductors. The contributions to this volume are arranged in 11 categories. The Organizing Committee would like to acknowledge all participants, who contributed to the great success of this symposium on a growing field in both physics and chemistry. The editors express their gratitude to the members of the Organizing and Executive Committees for their cooperation. We also wish to thank Dr. H. Lotsch of Springer-Verlag for his management of the publication and Miss S. Shibata for her assistance in editing this volume.

In this volume, the shock compression technology of materials is described in parallel with the latest research results and their background. In the past, this type of technology was developed in connection with military techniques by certain particular research organizations. For this reason, researchers of materials in general have had less opportunity to make use of the technology. The conventional technology of shock compression has now been established, and is recognized as being remarkably useful as a means of materials science study. The feasibility of shock compression technology is dealt with in this book, as well as the latest research results for general material scientists. The shock synthesis of ceramics and intermetallic compounds, as well as shock compression behavior, are also described. In contrast to conventional works of this kind, this book describes shock compression studies performed by material scientists.

This publication presents the proceedings of ICPMSE-4, the fourth international conference on Protection of Materials and Structures from the Low Earth Orbit Space Environment, held in Toronto April 23-24, 1998. The conference was hosted and organized by Integrity Testing Laboratory Inc. (ITL), and held at the University ofToronto's Institute for Aerospace Studies (UTIAS). Twenty two industrial companies, six universities and fourteen government agencies from Canada, USA, United Kingdom, France, Israel, Russia, Ukraine and the Netherlands were represented by over 75 participants indicating increasing international co-operation in this critical arena of protection of materials in space. Twenty-seven speakers, world experts in their fields, delivered talks on a wide variety of topics on various aspects of material protection in space. Representatives from the Canadian, American, European and Israeli space agencies as well as from leading space research laboratories ofmajor aerospace industries gathered at UTIAS to discuss the latest developments in the field of material and structure protection from the harsh space environment.

Polymers continue to show almost amazing versatility. We have always known that polymers could be used for trinkets, toys and dishes. Now, however, we are no longer surprised to encounter these adaptable mate rials in almost every place we look. We find them in our cars, tools, electronic devices, building materials, etc. The use of polymeric mate rials in medicine is also well documented in previous books by one of the Editors (Gebelein) and by others. Likewise, the use of polymeric mate rials in pharmaceutical applications, especially in controlled release systems, is also well established. Nevertheless, the use of these ubiquitous chemicals is far less ob vious in the field of cosmetics, although modern cosmetic preparations rely heavily on polymers and this trend is certain to increase. This book brings together much of the basic information on polymers in cosmetics and compares this usage with similar applications in pharmaceutical and medical applications. Cosmetics, like medicine and pharmacy, dates back to antiquity. We can find uses of perfumes, balms and ointments in various old books, such as the Bible. For example, the use of ointments and balms is noted more than thirty eight times, and perfumes and related materials are cited at least twenty nine times in the Bible."

This volume summarizes the papers presented at the First Osaka University Macromolecular Symposium OUMS'93 on "Ordering in Macromolecular Systems," which was held at Senri Life Science Center, Osaka, Japan, on June 3 through June 6, 1993. The symposium covered the three topics, (1) Crystallization and Phase Transitions, (2) Polymer Liquid Crystals and (3) Block Copolymers, Polymer Blends and Surfaces, and invited leading scientists in these fields. At present any of these topics is a hot issue in itself and frequently taken up separately in many occasions. It is noted however that all these topics are correlated with each other with the keyword "Ordering" and their combination provides a unique feature of the present symposium in reflecting the interactions among investigators working in these important fields with the common ground expressed by the keyword "Ordering." Nineteen invited lectures and 40 posters of both experiment and theory were presented at the symposium, and the eighteen lectures and ten poster presentations contribute to this volume. In the first topic crystal structures and their transitions were discussed from kinetic as well as static points of view; attention was paid to give a molecular-level interpretation of the structure, phase transition and physical properties, using theories and simulations. The second topic was mainly concerned with static structures and thermodynamic properties of polymer liquid crystals including phase behaviours.

Diamond-based composites, with their advantages of hardness, high Young's modulus and the like, have demonstrated new and unusual features, such as stability to high temperatures and pressure shocks and a large internal surface that can be controlled to offer customised electrical, magnetic and optical properties, leading to efficient filters, absorbents, sensors and other tools for environmental control and monitoring. The current book covers the synthesis of materials, their characterization and properties, trends in high pressure and high temperature technologies, low pressure technologies, basic principles of DBC material science, and future developments in electronics, optics, industrial tools and components, biotechnology, and medicine. Wide band-gap materials are considered, ranging from molecular clusters, nanophase materials, growth, processing and synthesis. The processing of composite based materials can be classified into six basic methods: in situ growth, high pressure/high temperature catalytic conversion; mix and sinter (c-BN plus metal-ceramic polymer mix); direct sintering; direct polymorphic conversion; shock detonation; and SHS sintering.

These volumes, 7 and 8, of Fracture Mechanics of Ceramics constitute the proceedings of an international symposium on the fracture mechanics of ceramic materials held at Virginia Polytechnic Institute and State University, Blacksburg, Virginia on June 19, 20 and 21, 1985. These proceedings constitute the fourth pair of volumes of a continuing series of conferences. The theme of this conference, as the previous three, focused on the mechanical behavior of ceramic materials in terms of the characteristics of cracks, particularly the roles which they assume in the fracture process. The 78 contributed papers by over 100 authors and co-authors represent the current state of the field. They address many of the theoretical and practical problems of interest to those concerned with brittle fracture. The program chairmen gratefully acknowledge the financial assistance for the Symposium provided by the EXXON Foundation, the Army Research Office, the Natio~al Science Foundation, and the Office of Naval Research. Without their support, this conference simply would not have been possible. The suggestions of Drs. J. C. Hurt, R. C. Pohanka, and L. Toth were particularly helpful in assuring the success of this symposium. Special appreciation is extended to Professor J. I. Robertson, C. P. Miles Professor of History. whose presentation following the banquet on the American Civil War was very well received by the audience. Finally, we wish to also thank our joint secretaries, especially Karen Snider, for their patience and help in finally bringing these proceedings to press.

Liquid-crystalline phases are now known to be formed by an ever growing range of quite diverse materials, these include those of low molecular weight as well as the novel liquid-crystalline polymers, such phases can also be induced by the addition of a solvent to amphiphilic systems leading to lyotropic liquid crystals. Irrespective of the structure of the constituent molecules these numerous liquid-cl)'Stailine phases are characterised by their long range orientational order. In addition certain phases exhibit elements of long range positional order. Our understanding, both experimental and theoretical, at the molecular level of the static behaviour of these fascinating and important materials is now well advanced. In contrast the influence of the long range order; both orientational and positional, on the molecular dynamics in liquid Cl)'Stais is less well understood. In an attempt to address this situation a NATO Advanced Study Institute devoted to liquid ctystal dynamics was held at n Ciocco, Barga, Italy in September 1989. This brought together experimentalists and theoreticians concerned with the various dynamical processes occurring in all liquid crystals. The skills of the participants was impressively wide ranging; they spanned the experimental techniques used in the study of molecular dynamics, the nature of the systems investigated and the theoretical models employed to understand the results. While much was learnt it was also recognised that much more needed to be done in order to advance our understanding of molecular dynamics in liquid Cl)'Stais.

Experiments showinga rapid and reversible change ofcolor s eem likemagic and are always fascinating. The process involved, photochromism, has a few real and many potential applications. Photochromic glasses thatdarken int he s unlight (protecting eyes from excessive light intensity) and bleach ind im lighta re today a part ofe v eryday life. Organic photochromic compounds in plastic ophthalmic lenses, more comfortable to wear, are now competing with silversalts in glasses, despite the longer lifetime oft he inorganic system. This successful commercial application has given a new impetus to research in the general field of photo chromism, which had its most recent revival in the early eighties. The storyo forganic photochromism with its ups anddowns, from the breakthroughs oft he pioneering periodi n the fifties, through the hardtimes dueto the drawbacks of photodegradation, tot he recent successes is in many ways a saga. The upsurges in this domain were marked by an increasing flow of articles in scientific journals andt he publication of several books (in 1971, 1990, and 1992) that have collectedt he important accumulatedknowledge. Over this period, a considerable number ofpatents have been issued. International meetings have accompanied this activity, the most recent being held in 1993 (ISOP 93 atLes Embiez Island, France) and in 1996 (ISOP 96 inClearwater, Florida). Remark ably, these meetings had good representation from both academia and industry. The next ISOP is planned for 1999 in Fukuoka, Japan.

Gellan gum, a microbial polysaccharide, consisting of tetra-saccharide unit, glucose, glucuronic acid, glucose and rhamnose, forms a transparent gel which is heat-resistant in the presence of divalent cations. Since 1989, the collaborative research group was organised in the Research Group of Polymer Gels affiliated to the Society of Polymer Science, Japan, consisting of various laboratories with different disciplines to clarify the mechanism using the common purified sample. This special issue contains 19 papers on the molecular conformation, gel-sol transition, interaction of gellan and water, cations and sugar, based on rheology, NMR, ESR, DSC, light scattering, osmotic pressure, small angle x-ray scattering, dielectric measurement, atomic force microscopy and the industrial application of gellan gum presented at the 4th International Conference on Hydrocolloids - OCUIS '98 by the collaborative group members and by international experts.

Although polypropylene has been marketed since the 1950s, research and development in this area is still vigorous. The consumption of polypropylene over the years has been relatively high, mainly due to the steady improvement of its property profile. Polypropylene: Structures, Blends and Composites, in three separate volumes, reflects on the key factors which have contributed to the success of polypropylene, dealing with all aspects of structure-performance relationships relevant to thermoplastic polymers and related composites. Volume 1, Structure and Morphology, deals with polymorphism in polypropylene homo- and copolymers, where molecular and supermolecular structures are covered, and the processing-induced structure development of polypropylene, showing the interrelation between the processing-induced morphology and mechanical performance. Volume 2, Copolymers and Blends, contains comprehensive surveys of the nucleation and crystallisation behaviour of the related systems. It includes the development of morphology and its effects on rheological and mechanical properties of polypropylene-based alloys and blends and a review of polypropylene-based thermoplastic elastomers. Volume 3, Composites, gives a comprehensive overview of filled and reinforced systems with polypropylene as a matrix material, with the main emphasis on processing-structure-property-interrelationships. Chapters cover all aspects of particulate filled, chopped fibre-, fibre mat- and continuous fibre-reinforced composites. Interfacial phenomena, such as adhesion, wetting and interfacial crystallisation, are also included as important aspects of this subject.

This book is about thin films; what they are, how they are prepared, how they are characterized, and what they are used for. The contents of this book not only showcase the diversity of thin films, but also reveals the commonality among the work performed in a variety of areas. The chapters in this volume are based on invited papers presented by prominent researchers in the field at a Symposium on "Thin Films: Preparation, Characterization, Applications" at the 221st National Meeting of the American Chemical Society held in San Diego, California. The coverage of the symposium was extensive; topics ranged from highly-ordered metal adlayers on well-defined electrode surfaces to bio-organic films on non-metallic nanoparticles. An objective of this book is for the readers to be able to draw from the experience and results of others in order to improve and expand the understanding of the science and technology of their own thin films systems.

This volume contains written versions of the papers presented at the Second Inter national Conference on Amorphous and Crystalline Silicon Carbide and Related Materials (ICACSC 1988), which was held at Santa Clara University on Decem ber 15 and 16, 1988. The conference followed the First ICACSC held at Howard University, Washington DC, in December 1987 and continued to provide an in ternational forum for discussion and exchange of ideas and results covering the current status of research on SiC and related materials. ICACSC 1988 attracted 105 participants from five countries. The substantial increase in the number of papers compared with the previous year is an indication of the growing interest in this field. Of the 45 papers presented at the conference, 36 refereed manuscripts are included in this volume, while the remaining 9 appear as abstracts. The six invited papers provide detailed reviews of recent results on amorphous and crystalline silicon carbide materials and devices, as well as diamond thin films. The volume is divided into six parts, each covering an important theme of the conference.
