Defect and Microstructure Analysis by Diffraction is focused on extracting information on the real structure of materials from their diffraction patterns. The primary features of a powder diffraction pattern are determined by the "idealized" periodic nature of the crystal structure. With the advent of computer automation the techniques for carrying out qualitative, quantitative and structure analysis based on the primary pattern features rapidly matured. In general, the deviations of a particular specimen, from the ideal or perfect crystal structure, cause diffraction peak profiles to broaden and sometimes to become asymmetric. Thus, information on the real structure or microstructure of a specimen can be obtained from a careful study of the diffraction line profiles. The evolving techniques for microstructure analysis from diffraction patterns such as micro-strain, crystallite size, macro-strain and preferred orientation analysis require an ever more detailed understanding of the effects of crystallographic mistakes on peak assymmetry and the effect of the distribution of small crystallites on the tails of diffraction peaks. This book provides a comprehensive analysis of the fundamental theory and techniques for microstructure analysis from diffraction patterns and summarizes the current state of the art. This complete survey lays the foundation for the next and last major development in this field: the extraction of the full information in a powder pattern by the simulation of the full experimental pattern. The goal of this branch of science is to extract all of the information locked in the powder diffraction pattern including: the types and densities of stacking faults, the strain field produced by each, the anisotropic crystallite size and orientation, along with the size and strain distributions of each phase in a specimen. This book provides a complete summary of the developments of the twentieth century and points the way.

First published in 1996, All the Nations Under Heaven has earned praise and a wide readership for its unparalleled chronicle of the role of immigrants and migrants in shaping the history and culture of New York City. This updated edition of a classic text brings the story of the immigrant experience in New York City up to the present with vital new material on the city’s revival as a global metropolis with deeply rooted racial and economic inequalities.All the Nations Under Heaven explores New York City’s history through the stories of people who moved there from countless places of origin and indelibly marked its hybrid popular culture, its contentious ethnic politics, and its relentlessly dynamic economy. From Dutch settlement to the extraordinary diversity of today’s immigrants, the book chronicles successive waves of Irish, German, Jewish, and Italian immigrants and African American and Puerto Rican migrants, showing how immigration changes immigrants and immigrants change the city. In a compelling narrative synthesis, All the Nations Under Heaven considers the ongoing tensions between inclusion and exclusion, the pursuit of justice and the reality of inequality, and the evolving significance of race and ethnicity. In an era when immigration, inequality, and globalization are bitterly debated, this revised edition is a timely portrait of New York City through the lenses of migration and immigration.

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.

Thirty years ago American political life was all relentless, painful, and confounding: the Tet Offensive brought new intensity to the Vietnam War; President Lyndon Johnson would not seek re-election; Martin Luther King, Jr. and Robert Kennedy were assassinated; student protests rocked France; a Soviet invasion ended "socialism with a human face" in Czechoslovakia; the Mexican government massacred scores of peaceful demonstrators; and Richard M. Nixon was elected president. Any one of the events of 1968 bears claim to historical significance. Together they set off shock waves that divided Americans into new and contending categories: hawks and doves, old and young, feminists and chauvinists, straights and hippies, blacks and whites, militants and moderates. As citizens alive to their own time and as reporters responsible for making sense of it, journalists did not stand aside from the conflicts of 1968. In their lives and in their work, they grappled with momentous issues--war, politics, race, and protest.

The future of journalism isn't what it used to be. As recently as the mid-1960s, few would have predicted the shocks and transformations that have swept through the news business in the last three decades: the deaths of many afternoon newspapers, the emergence of television as people's primary news source and the quicksilver combinations of cable television, VCRs and the Internet that have changed our ways of reading, seeing, and listening.The essays in this volume seek to illuminate the future prospects of journalism. Mindful that grandiose predictions of the world of tomorrow tend to be the fantasies and phobias of the present written large-in the 1930s and 1940s magazines such as Scribner's, Barron's, and Collier's forecast that one day we would have an airplane in every garage-the authors of What's Next? have taken a more careful view.The writers start with what they know-the trends that they see in journalism today-and ask where will they take us in the foreseeable future. For some media, such as newspapers, the visible horizon is decades away. For others, particularly anything involving the Internet, responsible forecasts can look ahead only for a matter of years. Where the likely destinations of present trends are not entirely clear, the authors have tried to pose the kinds of questions that they believe people will have to address in years to come.While being mindful of the tremendous influence of technology, one must remember that computers, punditry, or market share will not ordain the future of journalism. Rather, it will be determined by the sum of countless actions taken by journalists and other media professionals. These essays, with their hopes and fears, cautions and enthusiasms, questions and answers, are an effort to create the best possible future for journalism. This volume will be of interest to media professionals, academics and others with an interest in the future of journalism.

The events of 1989 were the material of great reporting. They also revealed the power of journalism. Long before people in Central and Eastern Europe liberated themselves, they discovered democratic freedom, putting to print their own ideas and chronicling events of the day. Indeed, long before they had democracies in law, they had imagined them on paper.In the Solidarity network that produced books and leaflets and news bulletins, in the essays of Václav Havel, in the samizdat publishing house in Budapest that used a portable printing machine, Eastern Europeans demonstrated the organic link between journalism and self-government. They showed how journalism nurtures the imagination, dialogue, and honesty that are basic to democratic life.If history had ended in 1989, there would be cause for easy optimism. The changes that swept Central and Eastern Europe passed with relatively little bloodshed. But agonies of the former Yugoslavia, convulsions of the former Soviet Union, and enduring battles with censors and would-be censors bedevil emerging democracies. Not only does much remain for journalists to cover in Central and Eastern Europe, in some places there the fate of journalism is still an open question. For all these reasons, Reporting the Fall of European Communism explores, not only the events of 1989, but new stories that have emerged in Central and Eastern Europe over the past decade. This volume will be of interest to media professionals, academics and others with an interest in the power of journalism.
