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.

X-ray fluorescence spectroscopy, one of the most powerful and flexible techniques available for the analysis and characterization of materials today, has gone through major changes during the past decade.

Fully revised and expanded by 30%, X-Ray Fluorescence Spectrometry, Second Edition incorporates the latest industrial and scientific trends in all areas. It updates all previous material and adds new chapters on such topics as the history of X-ray fluorescence spectroscopy, the design of X-ray spectrometers, state-of-the-art applications, and X-ray spectra.

Ron Jenkins draws on his extensive experience in training and consulting industry professionals for this clear and concise treatment, covering first the basic aspects of X rays, then the methodology of X-ray fluorescence spectroscopy and available instrumentation. He offers a comparison between wavelength and energy dispersive spectrometers as well as step-by-step guidelines to X-ray spectrometric techniques for qualitative and quantitative analysis—from specimen preparation to real-world industrial application.

Favored by the American Chemical Society and the International Centre for Diffraction Data, X-Ray Fluorescence Spectrometry, Second Edition is an ideal introduction for newcomers to the field and an invaluable reference for experienced spectroscopists—in chemical analysis, geology, metallurgy, and materials science.

An up-to-date review of X-ray spectroscopic techniques. This proven guidebook for industry professionals is thoroughly updated and expanded to reflect advances in X-ray analysis over the last decade. X-Ray Fluorescence Spectrometry, Second Edition includes:

• The history of X-ray fluorescence spectrometry—new to this edition.
• A critical review of the most useful X-ray spectrometers.
• Techniques and procedures for quantitative and qualitative analysis.
• Modern applications and industrial trends.
• X-ray spectra—new to this edition.

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.

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.

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.
