Available in PDF, EPUB and Kindle. Book excerpt: L'ETUDE REALISEE AU COURS DE CETTE THESE A POUR OBJET DE PROGRESSER DANS LA CONNAISSANCE DES MECANISMES D'INSTABILITE. IL FAIT UN LIEN ENTRE LES ETUDES EXPERIMENTALES DE FONCTIONNEMENT DES INDUCTEURS ET UN PROGRAMME DE RECHERCHE SUR LA MODELISATION DIPHASIQUE INSTATIONNAIRE DES ECOULEMENTS CAVITANTS AU SEIN DES INDUCTEURS. L'ETUDE DES INSTABILITES DE CAVITATION DANS LES INDUCTEURS EST REALISEE PAR LA CONJUGAISON DE L'EXPLOITATION DE RESULTATS EXPERIMENTAUX POUR DES GEOMETRIES ET DES CONDITIONS DE FONCTIONNEMENT VARIEES ET PAR LA MISE EN UVRE D'UN MODELE DE CAVITATION INSTATIONNAIRE. LE MODELE A ETE APPLIQUE A UNE REPRESENTATION EN GRILLE D'AUBE D'UN INDUCTEUR. LES PREMIERS CALCULS ONT EU POUR BUT DE CARACTERISER LES PERFORMANCES DE LA GRILLE EN REGIME NON CAVITANT ET CAVITANT. LA DESCENTE EN DEBIT A PERMIS CONSTATER UN ECART ENTRE LES PREDICTIONS NUMERIQUES ET LES MESURES EXPERIMENTALES EXPLIQUE PAR LE RAPPORT DES SECTIONS D'ENTREE ET DE SORTIE. LA DESCENTE EN CAVITATION A PERMIS DE CARACTERISER ET D'EXPLIQUER TROIS PHASES DE LA COURBE DE PERFORMANCE CAVITANTE DUES A DES MODIFICATIONS DE L'ECOULEMENT LE LONG DE L'AUBE LORSQUE LA POCHE DE CAVITATION SE DEVELOPPE. LES CALCULS SUIVANT ONT PERMIS DE REALISER UNE CARTOGRAPHIE DES ZONES STABLES ET INSTABLES DE LA GRILLE SUR UNE LARGE PLAGE DE DEBITS ET DE NOMBRES DE CAVITATION. L'ANALYSE DE CES CALCULS A ALORS MIS EN EVIDENCE TROIS CONFIGURATIONS CAVITANTES SE DEVELOPPANT EN FONCTION DE LA VALEUR DU NOMBRE DE CAVITATION. LA COMPARAISON AVEC LES RESULTATS EXPERIMENTAUX A ALORS MONTRE UN BON ORDRE DE GRANDEURS DE L'ETENDUE DE LA ZONE INSTABLE.

Book excerpt: Physics and Chemistry of Interfaces Comprehensive textbook on the interdisciplinary field of interface science, fully updated with new content on wetting, spectroscopy, and coatings Physics and Chemistry of Interfaces provides a comprehensive introduction to the field of surface and interface science, focusing on essential concepts rather than specific details, and on intuitive understanding rather than convoluted math. Numerous high-end applications from surface technology, biotechnology, and microelectronics are included to illustrate and help readers easily comprehend basic concepts. The new edition contains an increased number of problems with detailed, worked solutions, making it ideal as a self-study resource. In topic coverage, the highly qualified authors take a balanced approach, discussing advanced interface phenomena in detail while remaining comprehensible. Chapter summaries with the most important equations, facts, and phenomena are included to aid the reader in information retention. A few of the sample topics included in Physics and Chemistry of Interfaces are as follows: Liquid surfaces, covering microscopic picture of a liquid surface, surface tension, the equation of Young and Laplace, and curved liquid surfaces Thermodynamics of interfaces, covering surface excess, internal energy and Helmholtz energy, equilibrium conditions, and interfacial excess energies Charged interfaces and the electric double layer, covering planar surfaces, the Grahame equation, and limitations of the Poisson-Boltzmann theory Surface forces, covering Van der Waals forces between molecules, macroscopic calculations, the Derjaguin approximation, and disjoining pressure Physics and Chemistry of Interfaces is a complete reference on the subject, aimed at advanced students (and their instructors) in physics, material science, chemistry, and engineering. Researchers requiring background knowledge on surface and interface science will also benefit from the accessible yet in-depth coverage of the text.

The 26 chapters of this book are divided into five parts. The first is devoted to the study of some problems of mass transfer in microchannels, turbulence, waves and plasma, while chapters regarding mass transfer with hydro-, magnetohydro- and electro- dynamics are collected in the second part. The third part deals with mass transfer in food, such as rice, cheese, fruits and vegetables, and the fourth focuses on mass transfer in some large-scale applications such as geomorphologic studies. The last part introduces several issues of combined heat and mass transfer phenomena. The book can be considered as a rich reference for researchers and engineers working in the field of mass transfer and its related topics.

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.

Available in PDF, EPUB and Kindle. Book excerpt: It was with no definite purpose of writing a series of Notes on the Minor Prophets as a whole, that I first began to take up various books of the twelve, in monthly installments in HELP AND FOOD FOR THE HOUSEHOLD OF FAITH. But after penning some notes on Habakkuk, Jonah, and Obadiah, I found my own soul helped, and an interest developed in the further study of these much-neglected portions of Scriptures, and so took up Hosea and the books following. I have sought to press their practical application as giving important teaching for a remnant people in a day of decline, while not neglecting their dispensational bearing. This, I am persuaded, is what is greatly needed at the present moment. If God be pleased to use the Notes for the stirring of His people's consciences and the comfort of their hearts, the desired end will be realized. H. A. IRONSIDE.
