This book was released on 2009-09-09 with total page 211 pages. Available in PDF, EPUB and Kindle. Book excerpt: Premier ouvrage spécifiquement consacré à ce couplage, La spectrométrie de masse en couplage avec la chromatographie en phase gazeuse se différencie des autres publications scientifiques dédiées à la spectrométrie de masse en abordant la technologie avec une réelle volonté didactique. Ce manuel propose une démarche ancrée dans la pratique et offre des atouts décisifs pour gagner en temps et en qualité : une approche simple et précise du principe de fonctionnement des spectromètres de masse utilisés en couplage GC-MS, avec un minimum d'équations mathématiques, un comparatif des différents types de sources, d'analyseurs et de détecteurs, une mise en avant des aspects pratiques tels que la stratégie de mise au point d'une méthode de dosage ou l'utilisation d'une bibliothèque de spectres, un inventaire des problèmes et des "pièges" habituellement rencontrés par les utilisateurs de couplage GC-MS, un recueil des erreurs les plus communément commises et les solutions claires pour s'en affranchir. Ces conseils sont illustrés par de nombreux exemples choisis dans des domaines aussi divers que la toxicologie ou l'analyse environnementale avec toujours un double objectif pour les utilisateurs : leur permettre de tirer rapidement le meilleur parti de leur spectromètre de masse, les assister dans la détermination du matériel et des méthodes les plus appropriés à un contexte analytique donné (identification structurale, dosages multi-résidus, détermination de composés à l'état de traces en matrices complexes, etc.).

This book was released on 2012-09-04 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: C’est avec une réelle volonté didactique que cet ouvrage aborde l’interprétation des spectres de masse pour confirmer ou élucider des structures chimiques. Les publications scientifiques dédiées à la spectrométrie de masse sont souvent complexes et présentent une approche très théorique, souvent difficile à comprendre et à mettre en pratique. Ce livre se fait fort, grâce à sa simplicité et à sa démarche ancrée dans la pratique, d’offrir aux débutants comme aux spécialistes du domaine, les clés de cette technique. Un premier chapitre présente des rappels de chimie organique nécessaires à une bonne compréhension des réactions impliquées. Dans un deuxième chapitre, les mécanismes de formation et de dissociation des ions sont détaillés : ruptures simples et réarrangements, fragmentations secondaires, etc. Ces mécanismes sont illustrés de nombreux exemples concrets. La seconde partie de cet ouvrage propose une cinquantaine d'exercices corrigés permettant d'acquérir maîtrise et autonomie. À la fois manuel universitaire et guide pratique quotidien, L’interprétation des spectres de masse en couplage GC-MS constitue une référence pour tous les utilisateurs de couplage GC-MS tels que les ingénieurs, techniciens, chercheurs, étudiants, etc., débutants ou confirmés, désireux d'interpréter judicieusement leurs spectres de masse. Outre l'élucidation structurale, la compréhension des mécanismes qui régissent l'interprétation des spectres permet l'amélioration des méthodes analytiques et la fiabilisation des résultats.

This book was released on 2020-02-20 with total page 556 pages. Available in PDF, EPUB and Kindle. Book excerpt: Food composition data are useful throughout the food system for nutrition-sensitive agriculture, improved processing methods that ensure greater nutrient retention in foods, nutrition labelling, and to inform, educate and protect consumers through food-based dietary guidelines, nutrition education and communication, and legislation. The FAO/INFOODS Food Composition Table for Western Africa (WAFCT 2019) is an update of the West African Food Composition Table of 2012, which lacked some important components, foods and recipes. WAFCT 2019 contains almost three times as many food entries and double the number of components, with increased overall data quality. Many of the data points from WAFCT 2012 have been replaced with better data – mostly analytical data from Africa, with a special emphasis on Western Africa. These improvements are essential to understanding the nutrient composition of foods in the region and to promoting their appropriate use. WAFCT 2019 is the result of four years of collaboration among INFOODS network researchers in Africa and the Nutrition and Food Systems Division of FAO, and was developed as part of the International Dietary Data Expansion (INDDEX) Project, implemented by Tufts University’s Gerald J. and Dorothy R. Friedman School of Nutrition Science and Policy, with funding from the Bill & Melinda Gates Foundation. These new data from WAFCT 2019 will support further research towards an expanded and improved evidence base and will support better, more informed decisions and effective policies and programmes for improved nutrition in Africa.

Available in PDF, EPUB and Kindle. Book excerpt: Since the end of World War II isotope geology has grown into a diversi fied and complex discipline in the earth sciences. It has progressed by the efforts of a relatively small number of specialists, many of whom are physi cists, chemists, or mathematicians who were attracted to the earth sciences by the opportunity to measure and to interpret the isotopic compositions of certain chemical elements in geological materials. The phenomenal growth of isotope geology during the last 25 years is an impressive indi cation of the success of their efforts. We have now entered into a new phase of development of isotope geology which emphasizes the application of the new tools to the solution of specific problems in the earth and planetary sciences. This requires the active participation of a new breed of geologists who understand the nature and complexity of geological problems and can work toward their solution by a thoughtful application of the principles of isotope geology. It is there fore necessary to explain these principles to earth scientists at large to enable them to make use of the new information which isotope geology can offer them.

Available in PDF, EPUB and Kindle. Book excerpt: The sheer volume of topics which could have been included under our general title prompted us to make some rather arbitrary decisions about content. Modification by irradiation is not included because the activity in this area is being treated elsewhere. We have chosen to emphasize chemical routes to modification and have striven to pre sent as balanced a representation of current activity as time and page count permit. Industrial applications, both real and potential, are included. Where appropriate, we have encouraged the contributors to include review material to help provide the reader with adequate context. The initial chapter is a review from a historical perspective of polymer modification and contains an extensive bibliography. The remainder of the book is divided into four general areas: Reactions and Preparation of Copolymers Reactions and Preparation of Block and Graft Copolymers Modification Through Condensation Reactions Applications The chemical modification of homopolymers such as polyvinylchlo ride, polyethylene, poly(chloroalkylene sulfides), polysulfones, poly chloromethylstyrene, polyisobutylene, polysodium acrylate, polyvinyl alcohol, polyvinyl chloroformate, sulfonated polystyrene; block and graft copolymers such as poly(styrene-block-ethylene-co-butylene block-styrene), poly(I,4-polybutadiene-block ethylene oxide), star chlorine-telechelic polyisobutylene, poly(isobutylene-co-2,3-dimethyl- 1,3-butadiene), poly(styrene-co-N-butylmethacrylate); cellulose, dex tran and inulin, is described.

Available in PDF, EPUB and Kindle. Book excerpt: Techniques of performing applied mineralogy investigations, and applications and capabilities of recently developed instruments for measuring mineral properties are explored in this book intended for practicing applied mineralogists, students in mineralogy and metallurgy, and mineral processing engineers. The benefits of applied mineralogy are presented by using in-depth applied mineralogy studies on base metal ores, gold ores, porphyry copper ores, iron ores and industrial minerals as examples. The chapter on base metal ores includes a discussion on the effects of liberation, particle sizes and surfaces coatings of Pb, Cu, Fe, Ca and So4- on the recoveries of sphalerite, galena and chalcopyrite. The chapter on gold discusses various methods of determining the quantities of gold in different minerals, including 'invisible' gold in pyrite and arsenopyrite, so that a balance of the distribution of gold among the minerals can be calculated. This book also discusses the roles of pyrite, oxygen, moisture and bacterial (thiobacillus ferrooxidans) on reactions that produce acidic drainage from tailings piles, and summarizes currently used and proposed methods of remediation of acidic drainage.

Download or read book Flexoelectricity in Liquid Crystals written by Agnes Buka and published by World Scientific. This book was released on 2013 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book intends to give a state-of-the-art overview of flexoelectricity, a linear physical coupling between mechanical (orientational) deformations and electric polarization, which is specific to systems with orientational order, such as liquid crystals. Chapters written by experts in the field shed light on theoretical as well as experimental aspects of research carried out since the discovery of flexoelectricity. Besides a common macroscopic (continuum) description the microscopic theory of flexoelectricity is also addressed. Electro-optic effects due to or modified by flexoelectricity as well as various (direct and indirect) measurement methods are discussed. Special emphasis is given to the role of flexoelectricity in pattern-forming instabilities. While the main focus of the book lies in flexoelectricity in nematic liquid crystals, peculiarities of other mesophases (bent-core systems, cholesterics, and smectics) are also reviewed. Flexoelectricity has relevance to biological (living) systems and can also offer possibilities for technical applications. The basics of these two interdisciplinary fields are also summarized.

This book was released on 2019-01-28 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: Food composition data provides food and nutrition sector, both private and public with the important guidelines in food labelling, assessment of nutrient intake to determine nutrition adequacy, diet formulation as well as in research and breeding. The information generated is also used to establish food-based dietary guidelines for dietary diversification and food fortification. They also help program managers in determining the relationships between disease outcome and nutrient intakes. The resultant information provides the evidence base for nutrition and health & agricultural policies in establishing how to meet the nutrient requirements in the population through diet. The Kenya Food Composition Tables [FCT] (2018) was developed following international guidelines from INFOODS considering all the required quality checks. It has three main sections: the first part of the book contains an introduction and user notes; the second section presents the actual food composition tables; the third section features photographies and descriptions of foods, to facilitate food identification. This publication will guide both county and national authorities in setting priorities in the implementation of food-based approaches to reduce the burden of malnutrition in the population and support nutrition-sensitive agricultural production.

Book excerpt: Chemistry explores the way atoms interact, the constitution of the stars, and the human genome. Knowledge of chemistry makes it possible for us to manufacture dyes and antibiotics, metallic alloys, and other materials that contribute to the necessities and luxuries of human life. In Transforming Matter, noted historian Trevor H. Levere emphasizes that understanding the history of these developments helps us to appreciate the achievements of generations of chemists. Levere examines the dynamic rise of chemistry from the study of alchemy in the seventeenth century to the development of organic and inorganic chemistry in the age of government-funded research and corporate giants. In the past two centuries, he points out, the number of known elements has quadrupled. And because of synthesis, chemistry has increasingly become a science that creates much of what it studies. Throughout the book, Levere follows a number of recurring themes: theories about the elements, the need for classification, the status of chemical science, and the relationship between practice and theory. He illustrates these themes by concentrating on some of chemistry's most influential and innovative practitioners. Transforming Matter provides an accessible and clearly written introduction to the history of chemistry, telling the story of how the discipline has developed over the years.

Book excerpt: Thickening Fat: Fat Bodies, Intersectionality, and Social Justice seeks to explore the multiple, variable, and embodied experiences of fat oppression and fat activisms. Moving beyond an analysis of fat oppression as singular, this book will aim to unpack the volatility of fat—the mutability of fat embodiments as they correlate with other embodied subjectivities, and the threshold where fat begins to be reviled, celebrated, or amended. In addition, Thickening Fat explores the full range of intersectional and liminal analyses that push beyond the simple addition of two or more subjectivities, looking instead at the complex alchemy of layered and unstable markers of difference and privilege. Cognizant that the concept of intersectionality has been filled out in a plurality of ways, Thickening Fat poses critical questions around how to render analysis of fatness intersectional and to thicken up intersectionality, where intersectionality is attenuated to the shifting and composite and material dimensions to identity, rather than reduced to an “add difference and stir” approach. The chapters in this collection ask what happens when we operationalize intersectionality in fat scholarship and politics, and we position difference at the centre and start of inquiry.
