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.

Although GC-MS (gas chromatography-mass spectrometry) finds applications in fields as diverse as the food processing industry, medicine, pharmacology, and environmental analysis, the few works that are dedicated to this use of mass spectrometry are generally highly complex and theoretical. Emphasizing the practical aspects of GC-MS, without neglect

Cet ouvrage illustre de façon claire et pédagogique les méthodes et les concepts qui sont à la base des progrès de la génomique en biologie végétale (grands programmes internationaux de séquençage, outils de la bio-informatique, méthodes d'analyse de l'expression des gènes incluant leurs produits métaboliques finaux et leur spécificité tissulaire et/ou cellulaire). Il rend compte des applications potentielles de la génomique dans les domaines de la génétique et de l'amélioration des plantes, de l'écophysiologie et de l'agronomie. Ce livre s'adresse aux étudiants de fin d'études universitaires ou agronomiques, aux professeurs de l'enseignement supérieur, aux techniciens, aux ingénieurs et scientifiques qui souhaitent acquérir des connaissances en génomique végétale.

With terrorist groups expanding their weapons of destruction beyond bombs and bullets, chemical and biological warfare agents aren't merely limited to the battlefield anymore. In some cases, they are now being used on a new front: major metropolitan cities. And in the Handbook of Chemical and Biological Warfare Agents, emergency response personnel-from HazMat and Police SWAT teams to Explosive Ordinance Disposal units-will find a myriad of information on how to deal with such incidents involving dangerous chemical and biological agents. The 504-page book is formatted into a series of indices developed to facilitate rapid access to key information on chemical, biological and toxin agents, with each index cross-referenced to all others. The wealth of data not only include the physical appearance, odor, signs and symptoms of dangerous materials such as nerve agents and vesicants, but the detection and removal of such agents and the treatment of victims. Author D. Hank Ellison, a former U.S. Environmental Protection Agency emergency responder and officer in the Chemical Corps who provides chemical and biological counterterrorism training to HazMat, Police SWAT and Explosive Ordinance Disposal teams, also includes a litany of guidelines from such sources as the US Army, DOT and other agencies.

This new, third volume of Cohen-Tannoudji's groundbreaking textbook covers advanced topics of quantum mechanics such as uncorrelated and correlated identical particles, the quantum theory of the electromagnetic field, absorption, emission and scattering of photons by atoms, and quantum entanglement. Written in a didactically unrivalled manner, the textbook explains the fundamental concepts in seven chapters which are elaborated in accompanying complements that provide more detailed discussions, examples and applications. * Completing the success story: the third and final volume of the quantum mechanics textbook written by 1997 Nobel laureate Claude Cohen-Tannoudji and his colleagues Bernard Diu and Franck Laloë * As easily comprehensible as possible: all steps of the physical background and its mathematical representation are spelled out explicitly * Comprehensive: in addition to the fundamentals themselves, the books comes with a wealth of elaborately explained examples and applications Claude Cohen-Tannoudji was a researcher at the Kastler-Brossel laboratory of the Ecole Normale Supérieure in Paris where he also studied and received his PhD in 1962. In 1973 he became Professor of atomic and molecular physics at the Collège des France. His main research interests were optical pumping, quantum optics and atom-photon interactions. In 1997, Claude Cohen-Tannoudji, together with Steven Chu and William D. Phillips, was awarded the Nobel Prize in Physics for his research on laser cooling and trapping of neutral atoms. Bernard Diu was Professor at the Denis Diderot University (Paris VII). He was engaged in research at the Laboratory of Theoretical Physics and High Energy where his focus was on strong interactions physics and statistical mechanics. Franck Laloë was a researcher at the Kastler-Brossel laboratory of the Ecole Normale Supérieure in Paris. His first assignment was with the University of Paris VI before he was appointed to the CNRS, the French National Research Center. His research was focused on optical pumping, statistical mechanics of quantum gases, musical acoustics and the foundations of quantum mechanics.

The international fragmentation of economic activities – from research and design to production and marketing – described through the lens of the global value chain (GVC) approach impacts the structure and performance of small and medium-sized enterprises (SMEs) agglomerated in economic clusters. The consolidation of GVCs ruled by global lead firms and the recession of 2008-09 exacerbated the pressures on cluster actors that based their competitive advantage on local systems, spurring an increasing heterogeneity, both across and within clusters, that is still overlooked in the literature. Drawing on detailed studies of different industries and countries, Local Clusters in Global Value Chains shows the co-evolutionary trajectories of clusters and GVCs, and the role of firms and their strategies in organizing manufacturing and innovation activities in the context of ongoing technological shifts. The book explores the tension between place-based variables and global drivers of change, and the possibility for territories containing such clusters to prosper in the new global scenario. By adopting insights from the GVC framework and management studies, the book discusses how the internationalization strategies of firms create opportunities as well as constraints for adaptive upgrading in clusters. This book is of interest to both researchers and policy-makers who are interested in the dynamic sources of competitive advantage in the global economy.
