Book excerpt: NOUS PRESENTONS DANS CE MEMOIRE UNE ETUDE DE L'UTILISATION DES CRISTAUX LIQUIDES EN PHASE SMECTIQUE, CONFINES ENTRE DEUX FIBRES OPTIQUES, POUR DES APPLICATIONS EN TELECOMMUNICATIONS OPTIQUES. LES CRISTAUX LIQUIDES PRESENTENT LES AVANTAGES DE POSSEDER UN IMPORTANT EFFET ELECTRO-OPTIQUE, DE PRESERVER LA CONTINUITE DE TRANSMISSION SUR FIBRE ET D'ETRE PEU COUTEUX. QUANT AU RECOURS A L'OPTIQUE FIBREE, LES PERTES D'INSERTION ET L'ENCOMBREMENT SONT DAVANTAGE LIMITES. L'ASSOCIATION DES DEUX EST DONC POTENTIELLEMENT INTERESSANTE MAIS CONSTITUE DES INCONNUES QUANT A LA FAISABILITE TECHNOLOGIQUE. NOUS AVONS ETUDIE DEUX APPLICATIONS POUR LES TELECOMMUNICATIONS OPTIQUES, LA COMPENSATION DE LA DISPERSION MODALE DE POLARISATION (PMD) PAR UN CONTROLEUR DE POLARISATION A CRISTAL LIQUIDE ET LE ROUTAGE OPTIQUE DE L'INFORMATION PAR UN COUPLEUR DIRECTIONNEL MACH-ZEHNDER A CRISTAL LIQUIDE. POUR CES APPLICATIONS, LE COMPOSANT ELEMENTAIRE RESTE IDENTIQUE. SEULS LE TYPE DE FIBRES MONOMODES (MONOCUR OU BICURS), LE TYPE ET L'EPAISSEUR DE CRISTAL LIQUIDE ENTRE LES DEUX FIBRES DIFFERENT DES DEUX APPLICATIONS. PARALLELEMENT, NOUS AVONS DEVELOPPE UNE TECHNOLOGIE DE CONFINEMENT DE CRISTAL LIQUIDE ENTRE DEUX FIBRES FERULEES. L'ETUDE DES PREMIERS PROTOTYPES A PERMIS DE VALIDER LA FAISABILITE TECHNIQUE CAR LA CAPACITE D'ALIGNEMENT DU CRISTAL LIQUIDE ENTRE DEUX FIBRES OPTIQUES ET DE COMMUTATION ONT ETE DEMONTREES. NEANMOINS CES PROTOTYPES NE SONT PAS OPTIMAUX EN CE QUI CONCERNE LE CONTROLE DE L'EPAISSEUR. L'ANALYSE DES DIFFERENTS FACTEURS NOUS A PERMIS D'IDENTIFIER TOUTEFOIS UN PROTOCOLE QUASI-DEFINITIF POUR LA REALISATION DE COMPOSANTS FIBRES.

Book Synopsis Introduction to Glass Science and Technology by : James E Shelby
Download or read book Introduction to Glass Science and Technology written by James E Shelby and published by Royal Society of Chemistry. This book was released on 2015-11-06 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a concise and inexpensive introduction for an undergraduate course in glass science and technology. The level of the book has deliberately been maintained at the introductory level to avoid confusion of the student by inclusion of more advanced material, and is unique in that its text is limited to the amount suitable for a one term course for students in materials science, ceramics or inorganic chemistry. The contents cover the fundamental topics of importance in glass science and technology, including glass formation, crystallization, phase separation and structure of glasses. Additional chapters discuss the most important properties of glasses, including discussion of physical, optical, electrical, chemical and mechanical properties. A final chapter provides an introduction to a number of methods used to form technical glasses, including glass sheet, bottles, insulation fibre, optical fibres and other common commercial products. In addition, the book contains discussion of the effects of phase separation and crystallization on the properties of glasses, which is neglected in other texts. Although intended primarily as a textbook, Introduction to Glass Science and Technology will also be invaluable to the engineer or scientist who desires more knowledge regarding the formation, properties and production of glass.

Book excerpt: Earthen architecture constitutes one of the most diverse forms of cultural heritage and one of the most challenging to preserve. It dates from all periods and is found on all continents but is particularly prevalent in Africa, where it has been a building tradition for centuries. Sites range from ancestral cities in Mali to the palaces of Abomey in Benin, from monuments and mosques in Iran and Buddhist temples on the Silk Road to Spanish missions in California. This volume's sixty-four papers address such themes as earthen architecture in Mali, the conservation of living sites, local knowledge systems and intangible aspects, seismic and other natural forces, the conservation and management of archaeological sites, research advances, and training.

Book Synopsis Adhesion between polymers and concrete / Adhésion entre polymères et béton by : H. R. Sasse
Download or read book Adhesion between polymers and concrete / Adhésion entre polymères et béton written by H. R. Sasse and published by Springer. This book was released on 2013-11-27 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Preface Adhesion is a phenomenon architects and civil engineers are not very familiar with. In other disciplines knowledge about surface properties and the background of bonding energies is also far from satisfactory; nevertheless there are many important· applications in concrete engineering, where adhesion is necessary for success and durability. These include: - coating and painting - repair of concrete surfaces - bonding of fresh to old concrete - crack injection - glueing of precast elements - glueing of steel to concrete, etc. In 1981 RILEM established the technical committee 52-RAC 'Resin Adherence to Concrete'. The main aims of the committee's work were - to collect research results and practical experiences - to initiate and coordinate research programs - to develop, on a scientific base, test methods for field and for laboratory purposes. One of the results of the committee's work is a state-of-the-art report, which will be presented orally as a General Report at the International Symposium ISAP '86, and will be printed either in the RILEM journal Materials and Structures or separately. Several test recommendations have been elaborated and will be prepared as drafts for the participants ofISAP '86. These are: - direct tensile test - pull-off test - direct shear test - slant shear test - four-point bending test - dynamic loading test - thermal compatibility test (two versions) - injectibility test.

Book excerpt: Cet ouvrage répond aux questionnements scientifiques posés sur les effets biologiques des phytomicronutriments (polyphénols, phytostérols, caroténoïdes, glucosinolates…), dans le double contexte de transition nutritionnelle et du vieillissement de la population, et dans le cadre du rôle potentiel de notre alimentation dans la gestion de notre santé. Fruit d'un travail collectif initié par l'Institut français pour la nutrition (IFN) Les phytomicronutriments présente : - une classification des différentes familles de phytomicronutriments, - les principaux facteurs de variation impactant sur les quantités ingérées et sur leur biodisponibilité, car les effets santé des phytomicronutriments dépendent de leurs niveaux de consommation et de leur biodisponibilité, - leur fonctionnalité puis leur impact dans des populations spécifiques (femmes ménopausées, sportifs et personnes âgées), - les bénéfices/risques de quelques classes de molécules, les plus étudiées : phyto-oestrogènes, phytostérols et caroténoïdes, - une illustration de la composition en phytomicronutriments dans des menus types et la possibilité de les repérer dans les aliments sur la base de la couleur de ces derniers. Cet ouvrage s'adresse aux scientifiques, aux professionnels de l'industrie alimentaire, aux professionnels de la santé, aux enseignants et aux étudiants dans le domaine de la nutrition et de la santé.
