Book excerpt: Ce travail est motivé par le besoin de nouveaux matériaux transparents dans l’infrarouge pour satisfaire aux exigeantes spécifications de l’imagerie thermique. La synthèse d’une nouvelle génération de verres transparents du visible au lointain infrarouge a été réalisée par addition d’halogénures d’alcalins au système GeSe2-Ga2Se3. Nous avons démontré que des vitrocéramiques transparentes dans l’infrarouge lointain pouvaient être obtenues de façon reproductible. Des cristaux, dont la taille inférieure à 100 nm peut être contrôlée, permettent une augmentation de la résistance aux chocs thermiques. L’aptitude à combiner le processus de céramisation et le moulage de verres est démontré. Afin d’améliorer les propriétés mécaniques des verres, des échanges ioniques entre alcalins ont atteint une profondeur de 15 μm dans le verre. Les changements d’indices surfaciques laissent entrevoir des possibilités d’application de couches anti-reflets ou de guide d’onde planaire.

Book excerpt: Ce travail de thèse s’inscrit dans un contexte de recherche de nouveaux matériaux composites: les vitrocéramiques transparentes dans l’infrarouge. Située entre les domaines de la chimie des matériaux vitreux de la mécanique et de l’optique, cette étude s’articule autour du développement d’un matériau transparent entre 3 et 12 μm ayant des propriétés mécaniques supérieures aux matériaux vitreux commercialisés. L’exploration de nombreux diagrammes vitreux à base de GeSe2-Ga2Se3 avec addition d’halogénures d’alcalin a été effectuée. Le dépôt de couches anti-reflets a été optimisé sur une composition spécifique, les propriétés optiques de ce verre ont été déterminées. De nouvelles vitrocéramiques possédant un faible coefficient de dilatation dans le système Ge-Ga-Se ont ensuite été réalisées et les mécanismes de cristallisation ont été étudiés par une étude structurale. Enfin, des essais d’échange ionique ont été développés, proposant ainsi une autre voie pour l’amélioration des propriétés mécaniques des verres de chalcogénures.

Available in PDF, EPUB and Kindle. Book excerpt: Afin de pouvoir collecter les rayonnements émis par les corps chauds dans les 2nde et 3ème fenêtres atmosphériques (3-5 μm et 8-12 μm), les caméras thermiques doivent être équipées de lentilles transparentes dans l'infrarouge. Les matériaux actuellement utilisés pour la conception des lentilles sont chers et leur mise en forme est complexe. Les verres de chalcogénures sont moins chers, possèdent une large transmission dans l'infrarouge et leur mise en forme est aisée. Cependant, leurs propriétés mécaniques relativement faibles et leur méthode de synthèse complexe et coûteuse en ampoule de silice limitent leur utilisation. Ce travail de thèse a consisté à l'exploration de nouvelles méthodes de synthèse pour ces verres et au développement de vitrocéramiques aux propriétés mécaniques renforcées. Une méthode combinant la mécanosynthèse et le frittage par Spark Plasma Sintering a été développée. Des verres et des vitrocéramiques de dimensions importantes ont été produits dans des temps réduits et à des températures moins élevées que par la méthode de synthèse classique. La possibilité de déposer des traitements antireflets efficaces sur des vitrocéramiques 80GeSe2-20Ga2Se3 a été démontrée, renforçant leur intérêt pour la production d'optiques infrarouges. De nouvelles applications potentielles pour ces vitrocéramiques ont également été étudiées. Une attaque chimique a permis la création de matériaux poreux en surface intéressants pour des applications de détection. L'addition de Pb et d'In aux verres GeSe2-Ga2Se3 a conduit à l'exploration de nouveaux diagrammes vitreux. Enfin, la luminescence dans l'infrarouge de vitrocéramiques dopées par les ions de terres rares a été étudiée.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1 957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 28 (thesis year 1 983) a total of 10,661 theses titles from 26 Canadian and 197 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 28 reports theses submitted in-1983, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Once treated as the absence of knowledge, ignorance today has become a highly influential topic in its own right, commanding growing attention across the natural and social sciences where a wide range of scholars have begun to explore the social life and political issues involved in the distribution and strategic use of not knowing. The field is growing fast and this handbook reflects this interdisciplinary field of study by drawing contributions from economics, sociology, history, philosophy, cultural studies, anthropology, feminist studies, and related fields in order to serve as a seminal guide to the political, legal and social uses of ignorance in social and political life.

Available in PDF, EPUB and Kindle. Book excerpt: This classic text, now in its sixth edition, combines a thorough coverage of the basic principles of civil engineering hydraulics with a wide-ranging treatment of practical, real-world applications. It now includes a powerful online resource with worked solutions for chapter problems and solution spreadsheets for more complex problems that may be used as templates for similar issues. Hydraulics in Civil and Environmental Engineering is structured into two parts to deal with principles and more advanced topics. The first part focuses on fundamentals, such as hydrostatics, hydrodynamics, pipe and open channel flow, wave theory, physical modelling, hydrology and sediment transport. The second part illustrates engineering applications of these principles to pipeline system design, hydraulic structures, river and coastal engineering, including up-to-date environmental implications, as well as a chapter on computational modelling, illustrating the application of computational simulation techniques to modern design, in a variety of contexts. New material and additional problems for solution have been added to the chapters on hydrostatics, pipe flow and dimensional analysis. The hydrology chapter has been revised to reflect updated UK flood estimation methods, data and software. The recommendations regarding the assessment of uncertainty, climate change predictions, impacts and adaptation measures have been updated, as has the guidance on the application of computational simulation techniques to river flood modelling. Andrew Chadwick is an honorary professor of coastal engineering and the former associate director of the Marine Institute at the University of Plymouth, UK. John Morfett was the head of hydraulics research and taught at the University of Brighton, UK. Martin Borthwick is a consultant hydrologist, formerly a flood hydrology advisor at the UK’s Environment Agency, and previously an associate professor at the University of Plymouth, UK.
