This is the first comprehensive book for all aspects of monodispersed particles, consisting of four parts: Part 1 for the fundamentals of the elementary processes; Part 2 for the preparation of monodispersed particles, including the general principles, explanations of almost all known monodispersed systems on the basis of their classification, and techniques for controlling their mean size, shape, internal structure, composition, heterojunction, surface modification, etc.; Part 3 for the analytical methods for the formation processes and the characterization of monodispersed products; Part 4 for applications of monodispersed particles to fundamental studies and practicle uses, such as photographic materials, ceramics, catalysts, magnetic recording materials, pigments, cosmetics, biological and medical devices, etc. This book not only covers the most of known uniform particles, including inorganic and polymer particles and their composites, from nanometers to a few hundreds of micrometers, but also compiles numerous references about 2000. While this book is organized from the fundamentals to the ultimate levels, the text is replete with new theories, developed for this book, and novel ideas of the author's own interpretation on the formation mechanisms throughout the whole volume. In this sense, this is a unique book, as entirely different from ordinary textbooks. Since the functions and dynamic behaviours of particles strongly depend on their size, well-defined monodispersed particles are ideal particulate materials for advanced devices as well as models for fundamental studies of colloid science. This may be the sheer reason for the persistent demands for the advent of a comprehensive book focussed on this subject.

Ce travail s'inscrit dans le cadre de l'application des lois de comportement des sols à la modélisation de deux barrages en terre et comporte trois parties. La première partie est une étude bibliographique du comportement des argiles compactées et utilisées comme matériaux de construction des barrages, des différents appareils de mesure in situ utilisés dans les barrages afin d'analyser leur comportement aussi bien pendant leur construction qu'après la mise en eau, et enfin des différents types de modèles rhéologiques utilisés en éléments finis. La deuxième partie concerne une étude d'auscultation de deux barrages en Tunisie, El Houareb (Tunisie centrale) et Lebna (région de Nabeul), équipés des dispositifs permettant de s'assurer de la bonne tenue des ouvrages. L'auscultation est orientée de façon à mesurer les grandeurs intéressantes pour les comparaisons futures avec le calcul. La troisième partie traite les étapes suivantes. - Etude générale sur la m odélisation du comportement mécanique et hydraulique des barrages en remblai. - Etude expérimentale obtenue sur les matériaux des barrages El Houareb et Lebna par des essais fiables. Les essais de mécanique des sols classique effectués sur les matériaux constituant les deux barrages sont complétés par des essais triaxiaux dont le déroulement a permis la détermination des paramètres des lois de comportement des sols. - Présentation des modèles utilisés dans le calcul d'une part et détermination des paramètres nécessaires pour le calcul d'autre part. L'identification des paramètres constitue une des parties les plus importantes et les plus délicates de notre étude. - Traitement numérique des deux barrages. L'étude comprend les analyses des déplacements et des contraintes dans le remblai et dans le sol de fondation dont les propriétés sont analogues ou différentes de celles du remblai. L'objet principal est de comparer les résultats des mesures d'auscultation a vec les prédictions fournies par les différents modèles de comportement d'inspirations diverses. Les résultats obtenus sont illustrés par de nombreux graphiques qui peuvent servir de base à d'autres analyses que celles exposées dans cette étude.

This fascinating new book examines strategies for experimental approaches to stiffness, strength and toughness testing of plastic and composite materials. These materials, being non-linear viscoelastic, impose constraints on testing which are absent from other types of material. This book covers the latest testing approaches for providing service-pertinent data within a limited budget and relates the structure of the tests and the functions that they serve to the intrinsic nature of the mechanical properties of plastic materials. Its aim is also to evaluate beneficial approaches to testing in t

This important handbook looks at how high performance fibres are designed and manufactured and covers their capabilities and applications. The high-modulus, high-tenacity (HM-HT) fibres fall naturally into three groups - polymer fibres such as aramids and polyethylene fibres; carbon fibres such as Kevlar; and inorganic fibres based on glass and ceramic fibres. The book shows how high performance fibres are being increasingly used for a wide range of applications including geotextiles and geomembranes, and for construction and civil engineering projects, as well as in specialist fibres within composite materials where their ability to fulfil demanding roles makes them an effective choice for the engineer and materials scientist.
