Book Description
A Science of Impurity is the first detailed history of the mobilization of chemistry (and later bacteriology) to meet the public demand for good water. It also offers a perspective on understanding how modern physical sciences are tapped to ensure public good. A Science of Impurity explores the social framework in which chemists came to work on problems of water quality, the strategies they used to study the environment, their conclusions and their role in dealing with a fearful public. For historians of science, researchers and planners in the water industry.

Book Description
Recent regulations on heavy metal testing have required the pharmaceutical industry to monitor a suite of elemental impurities in pharmaceutical raw materials, drug products and dietary supplements. These new directives s are described in the new United States Pharmacopeia (USP) Chapters , , and , together with Q3D, Step 4 guidelines for elemental impurities, drafted by the ICH (International Conference on Harmonization of Technical Requirements for Registration of Pharmaceuticals for Human Use), a consortium of global pharmaceutical associations, including the European Pharmacopeia (Ph.Eur.), the Japanese Pharmacopeia (JP) and the USP. This book provides a complete guide to the analytical methodology, instrumental techniques and sample preparation procedures used for measuring elemental impurities in pharmaceutical and nutraceutical materials. It offers readers the tools to better understand plasma spectrochemistry to optimize detection capability for the full suite of elemental PDE (Permitted Daily Exposure) levels in the various drug delivery categories. Other relevant information covered in the book includes: The complete guide to measuring elemental impurities in pharmaceutical and nutraceutical materials. Covers heavy metals testing in the pharmaceutical industry from an historical perspective. Gives an overview of current USP Chapters and and ICH Q3D Step 4 Guidelines. Explains the purpose of validation protocols used in Chapter , including how J-values are calculated Describes fundamental principles and practical capabilities of ICP-MS and ICP-OES. Offers guidelines about the optimum strategy for risk assessment Provides tips on how best to prepare and present your data for regulatory inspection. An indispensable resource, the fundamental principles and practical benefits of ICP-OES and ICP-MS are covered in a reader-friendly format that a novice, who is carrying out elemental impurities testing in the pharmaceutical and nutraceutical communities, will find easy to understand.

Book Description
A discussion of the different mechanisms responsible for contamination together with a survey of their impact on device performance. The author examines the specific properties of main and rare impurities in silicon, as well as the detection methods and requirements in modern technology. Finally, impurity gettering is studied along with modern techniques to determine gettering efficiency. Throughout all of these subjects, the book presents only reliable and up-to-date data so as to provide a thorough review of recent scientific investigations.

Book Description
The United States Food and Drug Administration (FDA) and other regulatory bodies around the world require that impurities in drug substance and drug product levels recommended by the International Conference on Harmonisation (ICH) be isolated and characterized. Identifying process-related impurities and degradation products also helps us to understand the production of impurities and assists in defining degradation mechanisms. When this process is performed at an early stage, there is ample time to address various aspects of drug development to prevent or control the production of impurities and degradation products well before the regulatory filing and thus assure production of a high-quality drug product.This book, therefore, has been designed to meet the need for a reference text on the complex process of isolation and characterization of process-related (synthesis and formulation) impurities and degradation products to meet critical requlatory requirements.It's objective is to provide guidance on isolating and characterizing impurities of pharmaceuticals such as drug candidates, drug substances, and drug products. The book outlines impurity identification processes and will be a key resource document for impurity analysis, isolation/synthesis, and characterization. - Provides valuable information on isolation and characterization of impurities. - Gives a regulatory perspective on the subject. - Describes various considerations involved in meeting regulatory requirements. - Discusses various sources of impurities and degredation products.

Book Description
Introduces the central issues in the philosophy of chemistry. Mobilizing the theme of impurity, this book explores the tradition of chemistry's negative image. It argues for the positive philosophical value of chemistry, reflecting its characteristic practical engagement with the material world.

Book Description
Although Francisco Franco courted the Nazis as allies during the Spanish Civil War in the late 1930s, the Spanish dictator's racial ideals had little to do with the kind of pure lineage that obsessed the Nazis. Indeed, Franco's idea of race -- that of a National Catholic state as the happy meeting grounds of many different peoples willingly blended together -- differed from most European conceptions of race in this period and had its roots in earlier views of Spanish racial identity from the late nineteenth and early twentieth centuries. In Impurity of Blood, Joshua Goode traces the development of racial theories in Spain from 1870 to 1930 in the burgeoning human science of anthropology and in political and social debates, exploring the counterintuitive Spanish proposition that racial mixture rather than racial purity was the bulwark of national strength. Goode begins with a history of ethnic thought in Spain in the medieval and early modern era, and then details the formation of racial thought in Spain's nascent human sciences. He goes on to explore the political, social, and cultural manifestations of racial thought at the dawn of the Franco regime and, finally, discusses its ramifications in Francoist Spain and post--World War II Europe. In the process, he brings together normally segregated historiographies of race in Europe. Goode analyzes the findings of Spanish racial theorists working to forge a Spanish racial identity in the late nineteenth and early twentieth centuries, when race and racial sciences were most in vogue across Europe. Spaniards devised their own racial identities using scientifically substantiated racial ideas and confronted head-on the apparent limitations of Spain's history by considering them as the defining characteristics of la raza española. The task of the Spanish social sciences was to trace the history of racial fusion: to study both the separate elements of the Spanish composition and the factors that had nurtured them. Ultimately, by exploring the development of Spanish racial thought between 1870 and 1930, Goode demonstrates that national identity based on mixture -- the inclusion rather than the exclusion of different peoples -- did not preclude the establishment of finely wrought and politically charged racial hierarchies. Providing a new comprehensive view of racial thought in Spain and its connections to the larger twentieth-century formation of racial thought in the West, Impurity of Blood will enlighten and inform scholars of Spanish and European history, racial theory, historical anthropology, and the history of science.

Book Description
Personal impurity caused by childbirth, menstrual blood or death is an issue of concern prevalent in many cultures. In Japan, the generic term for these kinds of impurities is kegare and death impurity, a sub-type of kegare, is known as shi-e. The major topic of this book is death impurity. The definition and genesis of shi-e are explained. In addition, details of the influence shi-e had on ancient Japanese society as well as its continuing influence on modern Japanese society are given. Three hypotheses are stated and supported: (1) the shi-e concept began in Japan during the Yayoi period (300 BC - 300 AD) rather than at a later date as previously hypothesized; (2) the basis for the aversion to dead bodies, i.e. shi-e, is that corpses remind people of the fact that they will soon die; (3) Buddhism and Shintoism merged in Japan because of the impact of shi-e on Shintoism. This book concludes with some comments on the relevance of knowledge of the death impurity for students of Japanese history, culture and society.
