Book Description
Chemistry seeks to provide qualitative and quantitative explanations for the observed behaviour of elements and their compounds. Doing so involves making use of three types of representation: the macro (the empirical properties of substances); the sub-micro (the natures of the entities giving rise to those properties); and the symbolic (the number of entities involved in any changes that take place). Although understanding this triplet relationship is a key aspect of chemical education, there is considerable evidence that students find great difficulty in achieving mastery of the ideas involved. In bringing together the work of leading chemistry educators who are researching the triplet relationship at the secondary and university levels, the book discusses the learning involved, the problems that students encounter, and successful approaches to teaching. Based on the reported research, the editors argue for a coherent model for understanding the triplet relationship in chemical education.

Book Description
The subject of jamming and rheology is a broad and interdisciplinary one that is generating increasing interest. This book deals with one of the oldest unsolved problems in condensed matter physics - that of the nature of glass transition in supercooled liquids. Jamming and Rheology is a collection of reprinted articles from several fields, ranging from structural glasses to foams and granular materials. Glassy relaxation and constrained dynamics (jamming) occur at all scales, from microscopic to macroscopic - in the glass transition of supercooled liquids, in fluids confined to thin films, in the structural arrest of particles such as granular materials, and in foams which must be driven by an applied stress in order to flow. Because jamming occurs at the transition between where a flow occurs and where motion stops, it is hoped that there may be a universal feature that describes this transition in all systems. This volume shows that the systems described above share many common phenomenological features, and covers work done by a wide range of scientists and technologists working in areas from physics to chemistry to chemical and mechanical engineering.

Book Description
Fundamentals of Friction, unlike many books on tribology, is devoted to one specific topic: friction. After introductory chapters on scientific and engineering perspectives, the next section contains the necessary background within the areas of contact mechanics, surfaces and adhesion. Then on to fracture, deformation and interface shear, from the macroscopic behavior of materials in frictional contact to microscopic models of uniform and granular interfaces. Lubrication by solids, liquids and gases is presented next, from classical flow properties to the reorganization of monolayers of molecules under normal and shear stresses. A section on new approaches at the nano- and atomic scales covers the physics and chemistry of interfaces, an array of visually exciting simulations, using molecular dynamics, of solids and liquids in sliding contact, and related AFM/STM studies. Following a section on machines and measurements, the final chapter discusses future issues in friction.

Book Description
Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 120. Earthquakes in urban centers are capable of causing enormous damage. The January 16, 1995 Kobe, Japan earthquake was only a magnitude 6.9 event and yet produced an estimated $200 billion loss. Despite an active earthquake prediction program in Japan, this event was a complete surprise. Similar scenarios are possible in Los Angeles, San Francisco, Seattle, and other urban centers around the Pacific plate boundary. The development of forecast or prediction methodologies for these great damaging earthquakes has been complicated by the fact that the largest events repeat at irregular intervals of hundreds to thousands of years, resulting in a limited historical record that has frustrated phenomenological studies. The papers in this book describe an emerging alternative approach, which is based on a new understanding of earthquake physics arising from the construction and analysis of numerical simulations. With these numerical simulations, earthquake physics now can be investigated in numerical laboratories. Simulation data from numerical experiments can be used to develop theoretical understanding that can be subsequently applied to observed data. These methods have been enabled by the information technology revolution, in which fundamental advances in computing and communications are placing vast computational resources at our disposal.

Book Description
Excerpt from Microscopic and Macroscopic Models in Plasma Physics One is frequently presented with the alternative of studying a physical problem with a detailed and difficult microscopic model or a less cluttered and simpler, but not so clearly applicable, macroscopic model. The microsc0pic detail can be not only burdensome but, on occasion, even irrelevant; we recall from statistical mechanics the existence of macroscopic laws that are almost independent of particular molecular properties or motions. For classical fluids, we have recourse to experiment and to the (quite difficult and easily misinterpreted) theoretical derivation of macroscopic laws. For a plasma, unfortunately, experimental knowledge is not yet comprehensive enough to provide any significant degree of synthesis. Thus theoretical derivation of macroscopic laws (at least as difficult and as risky as for an ordinary gas) is our only alternative at present.

Book Description
Designed to be used as a graduate-level text and as an engineering reference work, "Continuum Electromechanics" presents a comprehensive development of its subject--the interaction of electromagnetic forces and ponderable media, the mechanical responses to electromagnetic fields, and the reciprocal effects of the material motions produced by those fields. The author's approach is highly interdisciplinary, and he introduces fundamental concepts from such subjects as electrohydrodynamics, magnetohydrodynamics, plasma physics, electron beam engineering, fluid mechanics, heat transfer, and physical chemistry.The applications of continuum electromechanics are also remarkably diverse, and many of them are treated in the book, both because of their intrinsic engineering importance and as a means of illustrating basic principles. Among these applications are the design of rotating machines and synchronous generators, polymer processing, magnetic melting and pumping in metallurgical operations, the processing of plastics and glass, the manufacture of synthetic fibers, inductive and dielectric heating, thermal-to-electrical energy conversion, the control of air pollution, the design of controlled-fusion devices, image processing and printing, the magnetic levitation and propulsion of vehicles, the study of films and membranes, and the analysis of the complex electrokinetic and physicochemical processes that underlie the sensing and motor functions of biological systems. Many of these applications are presented in the form of problems.The book consists of eleven chapters, entitled Introduction to Continuum Electromechanics; Electrodynamic Laws; Approximations, and Relations; Electromagnetic Forces, Force Densities, and Stress Tensors; Electromechanical Kinematics; Energy-Conversion Models and Processes; Charge Migration, Convection, and Relaxation; Magnetic Diffusion and Induction Interactions; Laws, Approximations, and Relations of Fluid Mechanics Statics and Dynamics of Systems Having a Static Equilibrium; Electromechanical Flows; Electromechanics with Thermal and Molecular Diffusion; and Streaming Interactions.
