Book excerpt: L'INDUSTRIE PETROLIERE S'INTERESSE A LA SIMULATION MOLECULAIRE POUR PREDIRE LES PROPRIETES D'EQUILIBRE (EQUILIBRES DE PHASE) ET LES PROPRIETES DE TRANSPORT (VISCOSITE, COEFFICIENTS DE DIFFUSION, ) DE FLUIDES COMPLEXES DANS UN CADRE THEORIQUE UNIFIE. LA PREMIERE PARTIE DE LA THESE TRAITE DU CALCUL DIRECT DU POINT DE BULLE D'UN FLUIDE MULTICONSTITUANT. ON PROPOSE DE CONSIDERER UN SYSTEME DANS LEQUEL LE NOMBRE DE MOLECULES DE CHAQUE ESPECE EST IMPOSE DANS LA PHASE LIQUIDE ET FLUCTUANT DANS LA PHASE VAPEUR, LE VOLUME GLOBAL ETANT IMPOSE. L'ANALYSE THEORIQUE MONTRE QU'IL NE S'AGIT PAS D'UN ENSEMBLE STATISTIQUE VRAI, MAIS D'UN PSEUDO-ENSEMBLE OU L'EGALITE DES PRESSIONS EST SATISFAITE. IL EST POSSIBLE D'IMPOSER A LA PHASE VAPEUR LE POTENTIEL CHIMIQUE ESTIME PAR DES TESTS D'INSERTION DANS LA PHASE LIQUIDE, AFIN DE SATISFAIRE LA CONDITION D'EQUILIBRE THERMODYNAMIQUE. APPLIQUE A DES MELANGES BINAIRES ET TERNAIRES DE FLUIDES SIMPLES OU D'ALCANES, CET ALGORITHME MONTRE DE BONS RESULTATS. LA DEUXIEME VOIE DE RECHERCHE A CONSISTE A OPTIMISER LES PARAMETRES DU POTENTIEL INTERMOLECULAIRE D'ATOMES UNIFIES ANISOTROPES POUR LES ALCANES LINEAIRES ET RAMIFIES. CHAQUE GROUPE COMME CH 2 OU CH 3 Y EST REPRESENTE PAR UN CENTRE DE FORCE UNIQUE, DONT LE CENTRE EST SITUE ENTRE L'ATOME DE CARBONE ET LES ATOMES D'HYDROGENE. L'OPTIMISATION, EFFECTUEE EN MAINTENANT INCHANGE LE POTENTIEL INTRAMOLECULAIRE, S'EST BASEE SUR LES PRESSIONS DE VAPEUR SATURANTE, LES MASSES VOLUMIQUES ET L'ENTHALPIE DE VAPORISATION DE TROIS ALCANES DANS UN LARGE DOMAINE DE TEMPERATURES. CETTE OPTIMISATION ABOUTIT A UNE TRES BONNE REPRESENTATION DES PROPRIETES THERMODYNAMIQUES DE L'ENSEMBLE DES ALCANES. LES EQUILIBRES DE PHASE DE MELANGES CO 2 - ALCANES ET LES COEFFICIENTS D'AUTO-DIFFUSION EN PHASE LIQUIDE SONT AUSSI BIEN PREDITS. CE BON COMPORTEMENT EST LOGIQUE, PUISQUE LES PARAMETRES OBTENUS PAR OPTIMISATION ONT UN BON SENS PHYSIQUE.

Available in PDF, EPUB and Kindle. Book excerpt: L'étude des propriétés d'équilibre de phases de mélanges moléculaires tels que les hydrocarbures par simulation moléculaire est intéressante à plus d'un titre. Elle permet notamment de modéliser des fluides d'intérêts pétrolier et gazier et de fournir des données à l'industrie dans un domaine de température et de pression difficilement accessible par l'expérience ou lorsqu'il s'agit de composés toxiques où les expériences sont difficiles à réaliser. La détermination et l'utilisation de modèles numériques réalistes et prédictifs pour des systèmes réels restent aujourd'hui des problèmes encore non résolus. Outre les questions de potentiel d'interaction intermoléculaire, l'obtention d'une bonne statistique sur ces systèmes comprenant de nombreux degrés de libertés est très délicate. Ce travail de recherche s'est concentré dans trois directions. La première partie concerne la prédiction de propriétés d'équilibre de phase, par simulation moléculaire de Monte Carlo, de composés particulièrement toxiques présents à l'état de traces dans certains gaz naturels: les composés organomercurés. Sa mise en œuvre passe par le développement d'un potentiel intermoléculaire adapté à ces composés pour ensuite établir des diagrammes d'équilibre liquide-vapeur comme celui du mélange diméthylmercure-pentane. La deuxième partie du travail consiste à calculer les dérivées secondes du potentiel thermodynamique et plus particulièrement le coefficient de Joule-Thomson. Pour obtenir ces propriétés thermodynamiques dérivées, une méthode de calcul direct de ces grandeurs à partir de fluctuations statistiques de données microscopiques a été mise au point. Appliquée aux corps purs puis à des gaz naturels, cette méthode montre de bons résultats. Enfin, la troisième partie de ce travail concerne le calcul préliminaire de certaines grandeurs thermodynamiques, le but étant de reproduire qualitativement et quantitativement leur divergence au voisinage du point critique.

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.

Available in PDF, EPUB and Kindle. Book excerpt: It is estimated that literally billions of residents in urban and peri-urban areas of Africa, Asia, and Latin America are served by onsite sanitation systems (e.g. various types of latrines and septic tanks). Until recently, the management of faecal sludge from these onsite systems has been grossly neglected, partially as a result of them being considered temporary solutions until sewer-based systems could be implemented. However, the perception of onsite or decentralized sanitation technologies for urban areas is gradually changing, and is increasingly being considered as long-term, sustainable options in urban areas, especially in low- and middle-income countries that lack sewer infrastructures. This is the first book dedicated to faecal sludge management. It compiles the current state of knowledge of the rapidly evolving field of faecal sludge management, and presents an integrated approach that includes technology, management, and planning based on Sandecs 20 years of experience in the field. Faecal Sludge Management: Systems Approach for Implementation and Operation addresses the organization of the entire faecal sludge management service chain, from the collection and transport of sludge, and the current state of knowledge of treatment options, to the final end use or disposal of treated sludge. The book also presents important factors to consider when evaluating and upscaling new treatment technology options. The book is designed for undergraduate and graduate students, and engineers and practitioners in the field who have some basic knowledge of environmental and/or wastewater engineering.

Available in PDF, EPUB and Kindle. Book excerpt: In this book, renowned scientists describe the various techniques used to detect and characterize extrasolar planets, or exoplanets, with a view to unveiling the “tricks of the trade” of planet detection to a wider community. The radial velocity method, transit method, microlensing method, and direct imaging method are all clearly explained, drawing attention to their advantages and limitations and highlighting the complementary roles that they can play in improving the characterization of exoplanets’ physical and orbital properties. By probing the planetary frequency at different distances and in different conditions, these techniques are helping astrophysicists to reconstruct the scenarios of planetary formation and to give robust scientific answers to questions regarding the frequency of potentially habitable worlds. Twenty years have passed since the discovery of a Jupiter-mass companion to a main sequence star other than the Sun, heralding the birth of extrasolar planetary research; this book fully conveys the exciting progress that has been achieved during the intervening period.
