Reforming Infrastructure
Electricity, natural gas, telecommunications, railways, and water supply, are often vertically and horizontally integrated state monopolies. This results in weak services, especially in developing and transition economies, and for poor people. Common problems include low productivity, high costs, bad quality, insufficient revenue, and investment shortfalls. Many countries over the past two decades have restructured, privatized and regulated their infrastructure. This report identifies the challenges involved in this massive policy redirection. It also assesses the outcomes of these changes, as well as their distributional consequences for poor households and other disadvantaged groups. It recommends directions for future reforms and research to improve infrastructure performance, identifying pricing policies that strike a balance between economic efficiency and social equity, suggesting rules governing access to bottleneck infrastructure facilities, and proposing ways to increase poor people's access to these crucial services.
Electron-beam Processes
Operation of the electron-beam process for welding, melting, and achining is described. The different classes of equipment for each of the 3 processes are dicussed, and commercialy available equipment, both domestic and foreign, is described and illustrated.
The Rotating Disc Electrode
Important advances in a subject are as often promoted by a new technique as by new concepts and theories. In the study of electrode reactions which involve diffusion in a primary or a secondary step, the development and use of techniques involving rotating disc electrodes and derived instrumentation based on ring-disc and split-ring systems has enabled advances of great importance to be made in the quantitative examination of diffusion processes at electrodes and their role in electrode processes generally. The technique allows precisely defined mass-transport conditions to be set up which can be subjected to exact mathe matical analysis so that quantitative treatment of hydrodynamic and dif...
Magnetic Nanomaterials
The book series Nanomaterials for the Life Sciences, provides an in-depth overview of all nanomaterial types and their uses in the life sciences. Each volume is dedicated to a specific material class and covers fundamentals, synthesis and characterization strategies, structure-property relationships and biomedical applications. The series brings nanomaterials to the Life Scientists and life science to the Materials Scientists so that synergies are seen and developed to the fullest. Written by international experts of various facets of this exciting field of research, the series is aimed at scientists of the following disciplines: biology, chemistry, materials science, physics, bioengineering, and medicine, together with cell biology, biomedical engineering, pharmaceutical chemistry, and toxicology, both in academia and fundamental research as well as in pharmaceutical companies. VOLUME 4 - Magnetic Nanomaterials This volume takes the reader on a tour showing how magnetic nanomaterials are used in the fields of diagnosis and therapy, as well as in tissue engineering and environmental applications.
Family Matters
Nariman Vakeel is a seventy-nine-year-old Parsi widower beset by Parkinson's disease and haunted by memories of the past. He lives with his two middle-aged step-children. When Nariman's illness is compunded by a broken ankle, he's forced to take up residence with his daughter Roxana, her husband Yezad and their two young sons. This new responsibility for Yezad, who is already besieged by financial worries, proves too much and pushes him into a scheme of deception - with devastating consequences.Wise and compassionate, Family Matters has all the richness, the gentle humour and the narrative sweep that have earned Rohinton Mistry the highest accolades.'It is rare to discover a novel in which the characters are so well drawn that you feel wrapped up in their problems, rather than just privy to them.' Independent on Sunday 'A brilliant novel from one of India's finest living novelists.' Observer
Molecular Beam Epitaxy Growth and Characerization of ZnO-based layers and Heterostructures
In semiconductor research a reliable epitaxial growth technique for growing high quality thin films and heterostructures is necessary. In the case of ZnO one of the main difficulties is the absence of suitable substrate material for ZnO epitaxial growth. Although special oxide material (for example ScAlMgO4) and ZnO bulk crystal can serve as lattice matched substrates, the quality of the substrates themselves, the size of the available wafer, and the expense do not encourage to use these lattice matched substrates for ZnO epitaxial growth. In the current research, a widely used low cost commercial substrate sapphire was employed to develop a reliable epitaxial growth technique and growth pro...
3D Imaging in Endodontics
This book is designed to provide the reader with a full understanding of the role of cone beam computed tomography (CBCT) in helping to solve many of the most challenging problems in endodontics. It will shorten the learning curve in application of this exciting imaging technique in a variety of contexts: difficult diagnostic cases, treatment planning, evaluation of internal tooth anatomy prior to root canal therapy, nonsurgical and surgical treatments, early detection and treatment of resorptive defects, and outcomes assessment. The ability to obtain an accurate 3D representation of a tooth and the surrounding structures by means of noninvasive CBCT imaging is changing the approach to clinical decision making in endodontics. Clinicians long accustomed to working in very small, three-dimensional spaces are no longer constrained by the limitations of two-dimensional imaging. The challenges of mastering the new technology can, however, be daunting. The detailed guidance contained in this book will help endodontists to take full advantage of the important benefits offered by CBCT.
