This book was released on 1992 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: CE TRAVAIL CONCERNE L'ETUDE DES PHENOMENES DE SURFACE PENDANT LE SECHAGE D'UN MILIEU POREUX: INTERACTIONS ENTRE L'ETAT DE SURFACE DU SOLIDE ET LA COUCHE LIMITE. LES EXPERIENCES SONT EFFECTUEES DANS UNE BOUCLE DE SECHAGE FERMEE. LES RESULTATS PERMETTENT DE SUIVRE L'EVOLUTION DE LA TEMPERATURE ET DE L'HUMIDITE DE SURFACE EN PARALLELE AVEC LA CINETIQUE DE SECHAGE. LES DONNEES DE SURFACE SONT OBTENUES A PARTIR D'UN ANALYSEUR D'HUMIDITE OPTIQUE ET D'UN PYROMETRE A INFRA-ROUGE. L'EFFET DE REDUCTION DE SURFACE HUMIDE, EN PREMIERE PHASE DE SECHAGE, EST ANALYSE POUR DIVERSES CLASSES DE MATERIAUX POREUX. UN MODELE DIFFUSIF DE SECHAGE UNIDIRECTIONNEL D'UN MILIEU POREUX NON HYGROSCOPIQUE EST MIS EN PLACE. SUIVANT LES HYPOTHESES CONSIDEREES SUR LE COEFFICIENT DE DIFFUSION, DEUX TYPES DE SOLUTION SONT PROPOSES ET COMPARES: ANALYTIQUE ET NUMERIQUE. ON ETUDIE, ENSUITE, LE SECHAGE BIDIMENSIONNEL D'UN LIT CONSTITUE PAR DES BRIQUES POREUSES. LES PROFILS DE VITESSE, DE TEMPERATURE ET D'HUMIDITE RELATIVE DE L'AIR DANS LA COUCHE LIMITE SONT ETABLIS EN UTILISANT, RESPECTIVEMENT, DES ANEMOMETRES (CTA ET CCA) ET DES SONDES CAPACITIVES. LES COEFFICIENTS DE TRANSFERT DE CHALEUR ET DE MASSE, OBTENUS PAR DIFFERENTES METHODES, SONT COMPARES. LE PROFIL DE TENEUR EN EAU LE LONG DU MILIEU POREUX, OBTENU PAR MESURE ELECTRIQUE, PERMET DE SUIVRE LE DEPLACEMENT DU FRONT DE SECHAGE. LE MODELE DIFFUSIF EST APPLIQUE AU CALCUL DE CE PROFIL. ON DEMONTRE QUE LA PREMIERE PERIODE DE LA PHASE DECROISSANTE EST L'EFFET D'UN ASSECHEMENT PARTIEL DE LA SURFACE

This book was released on 2019 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dans le secteur de l'énergie nucléaire, le séchage des matériaux irradiés (combustible usagé, déchets métalliques, ...) avant son transport ou stockage est une étape nécessaire. Ce séchage permet d'éviter tous risques liés à la présence d'eau résiduelle. En effet, même en faible quantité, l'eau peut être à l'origine de la formation d'hydrogène par radiolyse. Elle peut également provoquer une corrosion des matériaux présents (l'enceinte de confinement, la gaine du combustible, ...) ou encore une montée en pression par sa vaporisation. Dans le procédé mis en œuvre et préconisé par Orano, le chargement du contenu radioactif dans l'emballage qui servira au transport a lieu sous eau dans la piscine contenant le combustible usé. Une fois vidangée de son eau, l'emballage est mis sous vide primaire, cette baisse de pression provoque la vaporisation de l'eau résiduelle. La compréhension des phénomènes mis en jeu lors de ce séchage à basse pression, notamment les transferts de chaleur et de masse, a été identifiée comme un des verrous à l'optimisation de cette étape. Aussi, l'objectif principal de cette thèse est d'observer, comprendre et quantifier les phénomènes de transfert de chaleur et de masse dans des conditions opératoires similaires à celles du procédé Orano. Pour atteindre ces objectifs, deux approches complémentaires ont été mises en place. Dans un premier temps, un banc d'essai ad hoc a permis d'observer et de quantifier l'influence de paramètres (pression, température, surface d'évaporation, volume d'eau) sur les débits d'évaporation et coefficients d'évaporation obtenus. Pour aller plus loin dans la compréhension de ces observations, un modèle original a été développé sous le logiciel COMSOL. Ces simulations numériques ont permis de hiérarchiser les phénomènes prédominants suivant le mode opératoire choisi pour le séchage.

Download or read book Geologic Carbon Sequestration written by V. Vishal and published by Springer. This book was released on 2016-05-11 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: This exclusive compilation written by eminent experts from more than ten countries, outlines the processes and methods for geologic sequestration in different sinks. It discusses and highlights the details of individual storage types, including recent advances in the science and technology of carbon storage. The topic is of immense interest to geoscientists, reservoir engineers, environmentalists and researchers from the scientific and industrial communities working on the methodologies for carbon dioxide storage. Increasing concentrations of anthropogenic carbon dioxide in the atmosphere are often held responsible for the rising temperature of the globe. Geologic sequestration prevents atmospheric release of the waste greenhouse gases by storing them underground for geologically significant periods of time. The book addresses the need for an understanding of carbon reservoir characteristics and behavior. Other book volumes on carbon capture, utilization and storage (CCUS) attempt to cover the entire process of CCUS, but the topic of geologic sequestration is not discussed in detail. This book focuses on the recent trends and up-to-date information on different storage rock types, ranging from deep saline aquifers to coal to basaltic formations.

Download or read book Being Alive Well written by Naomi Adelson and published by University of Toronto Press. This book was released on 2000-12-15 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: 'Being Alive Well': Health and the Politics of Cree Well-Being is a critical medical anthropological analysis of health theory in the social sciences with specific reference to the James Bay Cree of northern Quebec. In it the author argues that definitions of health are not simply reflections of physiological soundness but convey broader cultural and political realities. The book begins with a treatise on the study of health in the social sciences and a call for a broader understanding of the cultural parameters of any definition of health. Following a chapter that outlines the history of the Whapmagoostui (Great Whale River) region and the people, Adelson presents the underlying symbolic foundations of a Cree concept of health, or miyupimaatisiiun. The core of this book is an ethnographic study of the Whapmagoostui Cree and their particular concept of "health" (miyupimaatisiiun or "being alive well"). That concept is mediated by history, cultural practices, and the contemporary world of the Cree, including their fundamental concerns about their land and culture. In the contemporary context, health – or more specifically, "being alive well" – for the Cree of Great Whale is an intimate fusion of social, political, and personal well-being, thus linking individual bodies to a larger socio-political reality.

Download or read book Agricultural English written by Georgeta Raţă and published by Cambridge Scholars Publishing. This book was released on 2012-04-25 with total page 385 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agricultural English is a collection of essays on the English of Agriculture. The approach is a linguistic one: the different aspects of the English used in the field of agriculture (agricultural practices, agricultural systems) and in some fields related to agriculture (agricultural zoology, agri-tourism, biology, botany, ecology, entomology, gastronomy, land measurement, plant pathology, zoology) are analysed from a morphological (combination, derivation), syntactical (nominal phrases, verbal phrases), lexical and lexicographical, semantic (homonymy, semantic fields, synonymy, terminology), pragmatic (academic discourse, idiom, metaphor), etymological (etymon, Latin heritage), and contrastive (English–Croatian, English–French, English–German, English–Romanian, Romanian–English) points of view. The book will appeal to agriculturists, animal breeders, professors, researchers, students, and translators from Croatian-, English-, French-, German-, and Romanian-speaking countries, active in their own countries or abroad. The types of academic readership it would appeal to include academic teaching staff, researchers and students in the fields of agriculture and related fields – agricultural zoology, agri-tourism, biology, botany, ecology, entomology, gastronomy, land measurement, plant pathology, and zoology.

This book was released on 2011-12-15 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Cambridge Yearbook of European Legal Studies provides a forum for the scrutiny of significant issues in EU Law, the law of the European Convention on Human Rights, and Comparative Law with a 'European' dimension, and particularly those issues which have come to the fore during the year preceding publication. The contributions appearing in the collection are commissioned by the Centre for European Legal Studies (CELS) Cambridge, a research centre in the Law Faculty of the University of Cambridge specialising in European legal issues. The papers presented are at the cutting edge of the fields which they address, and reflect the views of recognised experts drawn from the University world, legal practice, and the institutions of both the EU and its Member States. Inclusion of the comparative dimension brings a fresh perspective to the study of European law, and highlights the effects of globalisation of the law more generally, and the resulting cross fertilisation of norms and ideas that has occurred among previously sovereign and separate legal orders. The Cambridge Yearbook of European Legal Studies is an invaluable resource for those wishing to keep pace with legal developments in the fast moving world of European integration.
