This book is devoted to the problem of inelastic light scattering in semiconductors, i.e., to processes in which a photon impinges upon a serniconductor, creating or anihilating one or several quasi-particles, and then emerges with an energy somewhat different from that of the incident photon. In light scattering spectroscopy the incident photons are monochromatic; one measures the energy distribution of the scat tered photons with a spectrometer. Because of its monochromaticity, power, and collimation, lasers are ideal sources for light scattering spectroscopy. Consequently, developments in the field of light scattering have followed, in recent years, the developments in laser technology. T...
"The six modules aim to help skilled practitioners think critically and make effective decisions on the basis of solid knowledge and understanding of these complications. When using the modules for basic midwifery programmes, it is understood that students should already be competent in most of the basic skills such as measuring blood pressure, performing a vaginal examination, conducting a normal delivery and prevention of infection. The modules were released in 1996 and have now been updated in line with recent evidence and the WHO clinical guidelines. Each module can be taught independently of the other modules. It is however advisable to work through all of them."--World Health Organization website.
The work is intended especially as a supplement to the author's Sanskrit Grammar giving a fullness of detail that was not there practicable, nor admissible as part of the grammar itself, all the quotable roots of the language, with the tense and conjugation-systems made from them and with the noun and adjective (infinitival and participial) formation that attach themselves most closely to the verb and further with the other derivative noun and adjective-stems usually classed as primary. Everything given is dated with such accuracy as the information thus far in hand allows. In the indexes of stems given at the end of the volume, a classification is adopted which is intended to facilitate the historical comprehension of the language, by distinguishing what belongs respectively to its older and to its later periods from that which forms a part of it through the whole history.
This is the first book to describe thoroughly the many facets of doping in compound semiconductors. Equal emphasis is given to the fundamental materials physics and to the technological aspects of doping. The author describes various doping techniques, including doping during epitaxial growth, doping by implantation, and doping by diffusion. The key characteristics of all dopants that have been employed in III-V semiconductors are discussed. In addition, general characteristics of dopants are analyzed, including the electrical activity, saturation, amphotericity, autocompensation, and maximum attainable dopant concentration. Redistribution effects are important in semiconductor microstructur...
In the 1950s Shockley predicted that SiC would quickly replace Si as a result of its superior material properties. In many ways he was right and today there is an active industry based on SiC, with new achievements being reported every year. This book reviews the progress achieved in SiC research and development, particularly over the past 10 years. It presents the essential properties of 3C-, 6H- and 4H-SiC polytypes including structural, electrical, optical, surface and interface properties; describes existing key SiC devices and also the challenges in materials growth and device fabrication of the 21st century. Overall it provides an up-to-date reference book suitable for a broad audience of newcomers, graduate students and engineers in industrial R&D.

It is known that composites have insufficient transversal strength and rigidity, and low longitudinal shear modulus, compression and shear strength. This book describes methods to avoid these disadvantages by hybridization and spiral reinforcement of composites at the micro-level during the production stage. Mathematical models and design methods have been developed for various composites. The authors discuss the technology of spiral reinforcement and fillers, the structures and properties of spirally reinforced composites, binders, the manufacture of such composites, and the application of new materials and constructions. This informative text will be of interest to researchers, teachers and students in academia and also to industrial scientists and engineers involved in the development and application of new materials.
Sociopragmatics is a rapidly growing field and this is the first ever handbook dedicated to this exciting area of study. Bringing together an international team of leading editors and contributors, it provides a comprehensive, cutting-edge overview of the key concepts, topics, settings and methodologies involved in sociopragmatic research. The chapters are organised in a systematic fashion, and span a wide range of theoretical research on how language communicates multiple meanings in context, how it influences our daily interactions and relationships with others, and how it helps construct our social worlds. Providing insight into a fascinating array of phenomena and novel research directions, the Handbook is not only relevant to experts of pragmatics but to any reader with an interest in language and its use in different contexts, including researchers in sociology, anthropology and communication, and students of applied linguistics and related areas, as well as professional practitioners in communication research.
