Book Description
Since the beginning of the century the technological desire to master the fracture of metals, concrete or polymers has boosted research and has left behind an overwhelming amount of literature. In a field where it seems difficult to say anything simple and new, the editors and authors of this book have managed to do just that.The approach to fracture taken here was not conceived by mechanical engineers or material scientists. It is essentially the by-product of exciting developments that have occurred in the last ten to fifteen years within a branch of theoretical physics, called statistical physics. Concepts such as ``percolation'' and ``fractals'', as models for the properties of fracture are not often considered by engineers. A particular aim of this volume is to emphasize the fundamental role disorder plays in the breaking process.The main scope of the volume is pedagogical and is at the same time an overview of fracture mechanics for physicists and an introduction to new concepts of statistical physics for mechanics and engineers. To this end the first half of the book consists of introductory chapters and the second half contains the results that have emerged from this new approach.

Book Description
Telechelic polymers have garnered a great deal of scientific interest due to their reactive chain-end functions. This comprehensive book compiles and details the basic principles of and cutting-edge research in telechelic polyesters, polycarbonates, and polyethers, ranging from synthesis to applications. It discusses general strategies toward telechelic polymers, centered on the fundamental aspects of polycondensation reactions, of cationic, anionic, coordination-insertion, and activated monomer mechanisms of the metal-, enzyme-, or otherwise organocatalyzed ring-opening polymerization of cyclic monomers, and of postpolymerization chemical modification methods of polymer precursors. All main classes of polymers are covered separately, comprising polyhydroxyalkanoates, poly(ε-caprolactone)s, poly(lactic acid)s, polylactides, polycarobnates, and polyethers, including synthetic approaches as well as some illustrative, up-to-date examples and uses. The book also addresses applications of hydroxyl, thiol, amino, or acrylate/methacrylate end-capped polymers as starting materials for the preparation of diverse polymer architectures ranging from block, graft, and star-shaped polymers and micelles to precursors for ATRP macroinitiators, polyurethane copolymers, shape-memory polymers, or nanosized drug delivery systems. The book will appeal to advanced undergraduate- and graduate-level students of polymer science; researchers in macromolecular science, especially those with an interest in functional and reactive polymers; and polymer chemists in academia and industry.

Book Description
Methods of Foundation Engineering covers the theory, analysis, and practice of foundation engineering, as well as its soil mechanics and structural design aspects and principles. The book is divided into five parts encompassing 21 chapters. Part A is of an introductory character and presents a brief review of the various types of foundation structures used in civil engineering and their historical development. Part B provides the theoretical fundamentals of soil and rock mechanics, which are of importance for foundation design. Part C deals with the design of the footing area of spread footings and discusses the shallow foundation methods. Part D describes the methods of deep foundations, while Part E is devoted to special foundation methods. Each chapter in Parts C to E starts with an introduction containing a synopsis of the matter being discussed and giving suggestions as to the choice of a suitable method of foundation. This is followed by a description of the methods generally used in practice. Simple analyses of structures, presented at the conclusion of each chapter, can be carried out by a pocket calculator. This book will prove useful to practicing civil and design engineers.

Book Description
.For there to be progress in science, there must first be communication between experts of different disciplines. This is particularly true of modern biology which is becoming more and more of an interdisciplinary field. The present situation in cell biology clearly reflects this devel opment and demonstrates that the application of physical techniques was necessary before this field of biological research could be developed on an objective and quantitative basis. The utilization of optical phenomena as measuring parameters at the microscopic level has provided the basis for the development of quantitative cytochemistry. This rapidly growing extension of conventional cytochemistry and histochemistry is based on the visual oberservation of qualitative chemical criteria in correlation with the microscopically resolved structure of cells and tissues. Furthermore, the introduction into cytochemistry of such optical measuring techniques as ab sorption photometry, interferometry, and fluorometry, as well as the measurement of optical anisotropy, diffrac:tion and scattered light, has provided the methodological bridge for the ex change of knowledge between cell biology on the one hand and biochemistry, or molecular biology, on the other.

Book Description
This book provides an inventory of organic materials and products, the major components of all civil engineering projects, in terms of their scientific and technical background, including the regulations that cover their use and their predicted useful life. Such materials include: bitumen on the roads; geotextiles for retaining walls; membranes for bridges; tunnel and reservoir waterproofing; paint binders to protect metallic and concrete structures or to create road markings; injection resins; gluing products; concrete admixtures; and composite materials. The presentation is based on a physicochemical approach, which is essential if these products are to be considered as part of sustainable development: as such, those studying or working in these fields will find this an invaluable source of information.
