Book Description
This volume contains the proceedings of the NATO-Advanced Research Workshop (ARW) "Manipulation of atoms under high fields and temperatures: Applications", sponsored by the NATO Scientific Affairs Division, Special Programme on Nanoscale Science. This ARW took place in Summer '92, in the pleasant surroundings of the Hotel des Thermes at Charbonnieres les Bains -Lyon, France. Gathering some fifty experts from different fields, the ARW provided an opportunity to review the basic principles and to highlight the progress made during the last few years on the nanosources and the interactions between atomic-scale probes and samples. The motivation is to use the novel properties attached to the atomic dimensions to develop nanoscale technologies. The perception of the atomic-scale world has greatly changed since the discovery and development, in the early 80's, of Scanning Tunneling Microscopy (STM) by Binnig and Rohrer. Beyond the observation of individual atoms, which is now routine, the concept of playing with atoms has become commonplace. This has lead to the fashioning of tools at the atomic scale, to the deposition, the displacement and the creation of atomic structures and also to the knowledge of interactions and contacts between atoms. Nanotips ending with a single atom are sources of ultra-fine charged beams. They can be unique tools for high resolution observations, for micro fabrications by micro-machining and deposition at a scale not previously attainable, with a working distance less stringent than with STM devices.

Book Description
In this important new book, High argues that poverty reduction policies are formulated and implemented in fields of desire. Drawing on psychoanalytic understandings of desire, she shows that such programs circulate around the question of what is lacking. Far from rational responses to measures of need, then, the politics of poverty are unconscious, culturally expressed, mutually contradictory, and sometimes contrary to self-interest. Based on long-term fieldwork in a Lao village that has been the subject of multiple poverty reduction and development programs, High's account looks at implementation on the ground. While these efforts were laudable in their aims of reducing poverty, they often failed to achieve their objectives. Local people received them with suspicion and disillusionment. Nevertheless, poverty reduction policies continued to be renewed by planners and even desired locally. High relates this to the force of aspirations among rural Lao, ambivalent understandings of power and the "post-rebellious" moment in contemporary Laos.

Book Description
Quantum well devices have been the objects of intensive research during the last two decades. Some of the devices have matured into commercially useful products and form part of modern electronic circuits. Some others require further dev- opment, but have the promise of being useful commercially in the near future. Study of the devices is, therefore, gradually becoming compulsory for electronics specialists. The functioning of the devices, however, involve aspects of physics which are not dealt with in the available text books on the physics of semicond- tor devices. There is, therefore, a need for a book to cover all these aspects at an introductory level. The present book has been written with the aim of meeting this need. In fact, the book grew out of introductory lectures given by the author to graduate students and researchers interested in this rapidly developing area of electron devices. The book covers the subjects of heterostructure growth techniques, band-offset theory and experiments, electron states, electron-photon interaction and related phenomena, electron transport and the operation of electronic, opto-electronic and photonic quantum well devices. The theory as well as the practical aspects of the devices are discussed at length. The aim of the book is to provide a comprehensive treatment of the physics underlying the various devices. A reader after going through the book should find himself equipped to deal with all kinds of quantum well devices.

Book Description
Physical Acoustics: Principles and Methods, Volume V focuses on high frequency sound waves in liquids, solids, and gases, which are powerful tools for analyzing the molecular, domain wall, defect, and other types of motions that can take place in these media. This book discusses the measurements and techniques used for studying the effects of impurities on the anelastic properties of crystalline quartz. Comprised of six chapters, this volume starts with an overview of the various effects that can take place when waves are propagated in solids subject to high magnetic fields. This text then discusses the velocity changes and attenuation in solid and liquid metals. Other chapters consider the transmission of sound waves in superconductors and explore the giant quantum oscillations at high magnetic fields. This book discusses as well the X-ray diffraction topological method for investigating resonant vibrations. The final chapter deals with the transmission of hypersonic sound waves. This book is a valuable resource for physicists and engineers.

Book Description
The International Symposium on Superconductivity, which has been held annu ally since 1988, is a forum for presenting the most up-to-date information about a broad range of research and development in superconductivity, from funda mental aspects to applications. More than 10 years have passed since the discovery of oxide superconductors and since various developments of applications began. It may be said that the prospects for application of oxide superconductors recently have opened up. Great progress has been made toward practical use, for example, of the flywheel, which uses bulk materials, and the high-performance cryo-cooled magnet made of bismuth wire. These were the results of persistent efforts to develop materials from the viewpoint of materials science and engineering. Also important is the progress in comprehensive understanding of high temperature superconductivity. Unique electronic properties of cuprates such as the non-Fermi liquid normal state, spin-charge separation, spin gap, and d-wave symmetry were discussed at the symposium, as were the unique electromagnetic properties resulting from the low dimensionality of cuprates. In the field of new superconductors, many exotic materials have been discovered since 1986. A decade of work with cuprate superconductors is reviewed in this proceedings, and several of the newest materials are presented. These papers will be instructive for many researchers and for students who are to enter this field.
