Significant progress has occurred during the last few years in device technologies and these are surveyed in this new volume. Included are Si/(Si-Ge) heterojunctions for high-speed integrated circuits, Schottky-barrier arrays in Si and Si-Ge alloys for infrared imaging, III-V quantum-well detector structures operated in the heterodyne mode for high-data-rate communications, and III-V heterostructures and quantum-wells for infrared emissions.

Physics of Thin Films is one of the longest running continuing series in thin film science, consisting of twenty volumes since 1963. The series contains quality studies of the properties of various thinfilms materials and systems. In order to be able to reflect the development of today's science and to cover all modern aspects of thin films, the series, starting with Volume 20, has moved beyond the basic physics of thin films. It now addresses the most important aspects of both inorganic and organic thin films, in both their theoretical as well as technological aspects. Therefore, in order to reflect the modern technology-oriented problems, the title has been slightly modified from Physics of Thin Films to Thin Films. Key Features * Discusses the latest research about structure, physics, and infrared photoemissive behavior of heavily doped silicon homojunctions and Ge and GaAs-based alloy junctions * Reviews the current status of SiGe/Si quantum wells for infrared detection * Discusses key developments in the growing research on quantum-well infrared photodetectors (QWIPs) * Reviews Chois development of a family of novel three-terminal, multi-quantum well devices designed to improve high-temperature IR detectivity at long wavelengths * Describes recent studies aimed at using multi-quantum well structures to achieve higher performance in solar cell devices based on materials systems

Physics of Thin Films: Advances in Research and Development primarily deals with the influence of ions or optical energy on the deposition, properties, and etching on thin films. The book is a collection of five articles, with one article per chapter. Chapter 1 covers ionized cluster beam deposition; epitaxy; and film-formation mechanism. Chapter 2 discusses the activated reactive evaporation process; the deposition of refractory compounds; the role of plasma in the process; and its applications. Chapter 3 focuses on ion-beam processing of optical thin films; ion sources and ion-surface interactions; and the different kinds of bombardment involved. Chapter 4 deals with laser induced etching - its mechanisms, methods, and applications. Chapter 5 talks about contacts to GaAs devices; Fermi-level pinning; and heterojunction contacts. The book is recommended for physicists and engineers in the field of electronics who would like to know more about thin films and the progresses in the field.

In June 1978 the University of Rhode Island conducted a three-day short course on Recent Advances in Fiber Optics. followed by a two-day conference on the Physics of Fiber Optics. The course contained over a dozen lectures spanning a wide range of subject matter from fundamental theory to operational systems. presented by well-known scientists from industry. government and academic institutions. The conference. on the other hand. emphasized basic research on fiber optics and related subjects. This volume contains both papers presented at the conference. as well as the majority of the lectures from the course (the written versions were solicited on a voluntary basis for this volume). In some cases the papers in this volume represent expanded or otherwise modified versions of the original presentations. One of the principal aims of the conference was promulgation of novel and/or unconventional concepts. For this reason. the papers in this volume cover subjects such as bistable optical switches. fiber acoustic sensors. extruded infrared fibers. compressively coated glass fibers. and soliton propagation in fibers.

Since ancient times, plants have been used as a prime natural source of alternative medicines and have played an important role in our lives. The old tradition of medicinal plant application has turned into a highly profitable business in the global market, resulting in the release of a large number of herbal products. People have tried to find different sources of medicines to alleviate pain and cure different illnesses. Due to severe constraints of synthetic drugs and the increasing contraindications of their usage, there is a growing interest world over in the usage of natural products based on medicinal herbs, hence, there is an ever expanding market of herbs and herbal based medicinal preparations all over the world. This has culminated into an exponential increase in number of research groups in different geographical locations and generation of volume of research data in the field in a short span of time. The path breaking advancement in research methods and interdisciplinary approaches is giving birth to newer perspectives. Therefore, it becomes imperative to keep pace with the advancement in research and development in the field of medicinal herbs. There are a large number of researchers in different parts of the world working on various aspects of medicinal plants and ‘herbal medicines’. The idea is to bring their recent research work into light in the form of a book. The proposed book contains chapters by the eminent researchers in different countries and working with different disciplines of medicinal plants. Articles pertain to different disciplines such as: 1. Resources and conservation of medicinal plants 2. Biosynthesis and metabolic engineering of medicinal plants 3. Tissue culture, propagation and bioreactor technology of medicinal plants 4. Phytochemical research on medicinal plants 5. Herbal medicines and plant-derived agents in cancer prevention and therapy 6. Herbal medicines and plant-derived agents in metabolic syndrome management 7. Herbal medicines and plant-derived agents in modulation of immune-related disorders 8. Herbal medicines and hepatotoxicity The book will prove itself an asset for the researchers, professionals and also students in the area of medicinal plants and mechanism of their action.

From an informal group of a dozen faculty and graduate students at Temple University, the Jean Piaget Society grew in seven years to 500 members who have interests in the application of genetic epistemology to their own disciplines and professions. At the outset Piaget endorsed the concept of a society which bore his name and presented a major address on equilibration at the society's first symposium in May, 1971. Had he not done so the society would no doubt have remained a small parochial group, like so many others throughout the country, interested in Piaget and his theory. With the encouragement of Genevans and the leadership of its first four presidents, Lois Macomber, Barbara Press eisen, Marilyn Appel, and John Mickelson, the society undertook a number of programs to collect and disseminate the results of scholarly work in genetic epistemology. Particular emphasis was placed upon applications of Piaget's theory to developmental psychology, philos ophy, and education. One of these programs was the publication of an annual series on the development of knowing, of which this volume is the first. In 1973, the society asked Hans Furth with the assistance of Willis Overton and Jeanette Gallagher to initiate and plan a series of yearbooks with the result that in addition to this volume, a second volume on education was commissioned, and a third one on the decalage issue was planned.

This book provides a comprehensive update on the latest information and knowledge which emerged from translational and basic science research endeavors, targeting the regeneration of salivary glands. The coverage includes salivary gland growth and development, stem cell therapy, bioengineering of salivary glands, and perspectives on and practical approaches to restoration of secretory function. More specifically, among the individual topics addressed are the various types of stem cell of value for cell replacement therapy, technological advances with respect to 3D printing, gene therapy, organ culture of salivary glands, and surgical aspects of the feasibility and practicality of transplantation. Readers will find helpful practical guidance on functional restorations of damaged salivary glands and stimulating insights into potential future directions in salivary gland regeneration research. The authors are all acknowledged experts from a range of academic and clinical backgrounds. Accordingly, the book will be of interest not only to clinicians, such as general dental practitioners, oral medicine specialists, and surgeons who manage dry mouth patients, but also to biomedical engineers, stem cell researchers, and transplant surgeons.
