A deepening crisis in accountability in developing democracies has triggered much debate on accountability and the mechanisms needed for overcoming deficiencies of democracy. This book analyzes a wide variety of contemporary efforts to reform accountability systems in developing countries. It makes an original contribution to the debate by dealing with a variety of novel approaches to accountability and it combines these approaches in both a systematic and analytic fashion. The book also includes case study material on successful accountability initiatives.

When bombarded with X-rays, solid materials produce distinct scattering patterns similar to fingerprints. X-ray powder diffraction is a technique used to fingerprint solid samples, which are then identified and cataloged for future use—much the way the FBI keeps fingerprints on file. The current database of some 70,000 material prints has been put to a broad range of uses, from the analysis of moon rocks to testing drugs for purity.

Introduction to X-ray Powder Diffractometry fully updates the achievements in the field over the past fifteen years and provides a much-needed explanation of the state-of-the-art techniques involved in characterizing materials. It covers the latest instruments and methods, with an emphasis on the fundamentals of the diffractometer, its components, alignment, calibration, and automation.

The first three chapters outline diffraction theory in clear language, accessible to both students and professionals in chemistry, physics, geology, and materials science. The book's middle chapters describe the instrumentation and procedures used in X-ray diffraction, including X-ray sources, X-ray detection, and production of monochromatic radiation. The chapter devoted to instrument design and calibration is followed by an examination of specimen preparation methods, data collection, and reduction. The final two chapters provide in-depth discussions of qualitative and quantitative analysis.

While the material is presented in an orderly progression, beginning with basic concepts and moving on to more complex material, each chapter stands on its own and can be studied independently or used as a professional reference. More than 230 illustrations and tables demonstrate techniques and clarify complex material.

Self-contained, timely, and user-friendly, Introduction to X-ray Powder Diffractometry is an enormously useful text and professional reference for analytical chemists, physicists, geologists and materials scientists, and upper-level undergraduate and graduate students in materials science and analytical chemistry.

X-ray powder diffraction—a technique that has matured significantly in recent years—is used to identify solid samples and determine their composition by analyzing the so-called "fingerprints" they generate when X-rayed. This unique volume fulfills two major roles: it is the first textbook devoted solely to X-ray powder diffractometry, and the first up-to-date treatment of the subject in 20 years.

This timely, authoritative volume features:

• Clear, concise descriptions of both theory and practice—including fundamentals of diffraction theory and all aspects of the diffractometer
• A treatment that reflects current trends toward automation, covering the newest instrumentation and automation techniques
• Coverage of all the most common applications, with special emphasis on qualitative and quantitative analysis
• An accessible presentation appropriate for both students and professionals
• More than 230 tables and illustrations

Introduction to X-ray Powder Diffractometry, a collaboration between two internationally known and respected experts in the field, provides invaluable guidance to anyone using X-ray powder diffractometers and diffractometry in materials science, ceramics, the pharmaceutical industry, and elsewhere.

As communities in the United States and Europe confront shortages of disposal capacity, the growing solid waste stream increasingly threatens the environment.This important new book addresses a major policy question regarding the solid waste crisis: should municipalities charge households user fees for solid waste services? In her study of this issue, Professor Jenkins draws on a unique data set which relates the quantities of waste discarded and the prices charged to households for waste services in nine US communities. She thoroughly analyses the relationship between the quantity of waste that individuals discard and such socio-economic variables as household income, the age of individuals and the population density of the community. In addition she develops a utility maximization model that suggests that user fees do encourage people to recycle waste. Finally she provides simple instructions for forecasting the quantity of waste discarded by a particular community. This unique book will be essential reading not only for social scientists with an interest in the environment but also for government officials and community activists concerned with the solid waste crisis.

Gynecology is principally an operative specialty and the range of gynecologic procedures managed is constantly expanding due to improved instrumentation and minimally invasive techniques. Covering the entire spectrum of gynecologic surgery through a case-based, digestible format, procedures such as vaginal, transvaginal, hysteroscopic, laparoscopic, robotic, and abdominal procedures are included, as well as common surgical challenges and complications. For each case, a clinical vignette outlines the situation and the clinical context of the patient, followed by a comprehensive discussion of the evidence-based management approach and key teaching points. The decision to operate, contraindications, alternatives to surgery and preoperative counseling is discussed in detail along with the level of care needed for each case. Readers will improve their knowledge base of gynecologic surgery and gain multiple tools to overcome common surgical obstacles.

This straightforward introduction looks at the properties and reactions of main group organometallic compounds, placing particular emphasis on their applications in synthesis. Written in a simple, readable style, the book adopts a logical approach to this important area of organic chemistry, and provides the student with a clear account of all aspects of the field. Study problems are included at chapter ends, along with many suggestions for further reading.

In 1945 some experts still considered the so-called sound barrier an impenetrable wall, while winged rocket planes remained largely relegated to science fiction. But soon a series of unique rocket-powered research aircraft and the dedicated individuals who built, maintained, and flew them began to push the boundaries of flight in aviation's quest to move ever higher, ever faster, toward the unknown. Beyond Blue Skies examines the thirty-year period after World War II during which aviation experienced an unprecedented era of progress that led the United States to the boundaries of outer space. Between 1946 and 1975, an ancient dry lakebed in California's High Desert played host to a series of rocket-powered research aircraft built to investigate the outer reaches of flight. The western Mojave's Rogers Dry Lake became home to Edwards Air Force Base, NASA's Flight Research Center, and an elite cadre of test pilots. Although one of them-Chuck Yeager-would rank among the most famous names in history, most who flew there during those years played their parts away from public view. The risks they routinely accepted were every bit as real as those facing NASA's astronauts, but no magazine stories or free Corvettes awaited them-just long days in a close-knit community in the High Desert. The role of not only the test pilots but the engineers, aerodynamicists, and support staff in making supersonic flight possible has been widely overlooked. Beyond Blue Skies charts the triumphs and tragedies of the rocket-plane era and the unsung efforts of the men and women who made amazing achievements possible.
