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
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.

Book Description
Since the introduction of quantum mechanics, the general theory of solid state physics has developed very rapidly. To date, a number of good textbooks on general solid state physics have been written. However, research in solid state physics has become highly specialized and undertaken in narrow fields. There is thus a great need for elementary textbooks that deal in detail with the study of solids in a particular field in order to give students basic knowledge in that field. Metallic solids with an impurity, generally called alloys, are of immense importance from both fundamental and technological points of view. The pioneering work of Bloember gen and Rowland (1953) gave considerable impetus to the study of the electronic structure of metallic alloys. Serious theoretical study in this field started in 1960 and, during the last two decades, considerable success in understanding the electronic structure of simple metal alloys has been achieved. Nonetheless the theoretical study of dilute alloys of transition metals is still in its infancy. At present there are few review articles and original research papers that examine the role of an impurity with respect to the electronic structure and properties of metallic alloys. Because of the absence of an elementary textbook that presents a comprehensive account of different aspects of the electronic structure of metallic alloys, I have written this elementary textbook on the theory of the electronic structure of metallic alloys.

Book Description
This book emphasizes the importance of the fascinating atomistic insights into the defects and the impurities as well as the dynamic behaviors in silicon materials, which have become more directly accessible over the past 20 years. Such progress has been made possible by newly developed experimental methods, first principle theories, and computer simulation techniques. The book is aimed at young researchers, scientists, and technicians in related industries. The main purposes are to provide readers with 1) the basic physics behind defects in silicon materials, 2) the atomistic modeling as well as the characterization techniques related to defects and impurities in silicon materials, and 3) an overview of the wide range of the research fields involved.

Book Description
Impurity of Blood analyzes the proposition of Spanish racial thought in the late 19th and early 20th centuries that racial strength came from a fusion of different groups, rather than from a kind of racial purity. By providing a history of ethnic thought in Spain in the medieval and early modern era, and by studying the formation of racial thought in Spain's nascent human sciences and its political and cultural manifestations leading into the Franco regime, it provides a new view of racial thought in Europe and its connections to the larger twentieth century formation of racial thought in the West.
