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

Download or read book Terra 2008 written by Leslie Rainer and published by Getty Publications. This book was released on 2011-06-14 with total page 438 pages. Available in PDF, EPUB and Kindle. 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 Faecal Sludge Management by : Linda Strande
Download or read book Faecal Sludge Management written by Linda Strande and published by IWA Publishing. This book was released on 2014-08-15 with total page 428 pages. 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.
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 Synopsis How to Design Wastewater Systems for Local Conditions in Developing Countries by : David M. Robbins
Download or read book How to Design Wastewater Systems for Local Conditions in Developing Countries written by David M. Robbins and published by IWA Publishing. This book was released on 2014-03-15 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a practical handbook providing a step-by-step approach to the techniques used for characterizing wastewater sources and investigating sites where collection, treatment and reuse/disposal technologies will be installed. It is intended to help enable local implementation of on-site and decentralized wastewater management system (DWMS)for wide scale use in development settings. How to Design Wastewater Systems for Local Conditions in Developing Countries helps local service providers and regulatory officials make informed decisions through the use of tools, checklists and case studies. It includes a link to a web based community of on-site and decentralized wastewater professionals, which contains related tools and case studies. This handbook serves as a reference for training classes, certification programs, and higher education programs in civil and sanitary engineering. There is an increasing interest on the part of local government officials and private sector service providers to implement wastewater treatment systems to solve sanitation problems. The model presented in this handbook promotes activities that first generate data related to source and site conditions that represent critical inputs, and then applies this information to the technology selection process. Matching the most appropriate technologies to the specific needs of the wastewater project is the key that leads to long term sustainability. How to Design Wastewater Systems for Local Conditions in Developing Countries is an invaluable resource for public sector decision makers and private sector service providers in developing countries. It is also a useful text for students at engineering colleges in developing countries interested in taking a class that teaches the methods of decentralized wastewater management system (DWMS) development.
Book Synopsis Fundamentals of Latex Film Formation by : Joseph Keddie
Download or read book Fundamentals of Latex Film Formation written by Joseph Keddie and published by Springer Science & Business Media. This book was released on 2010-02-18 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book has emerged out of our long-time research interests on the topic of latex film formation. Over the years we have built up a repertoire of slides used in conference presentations, short courses and tutorials on the topic. The story presented in this book has thereby taken shape as it has been told and re-told to a mix of academic and industrial audiences. The book presents a wide body of work accumulated by the polymer colloids community over the past five decades, but the selection of examples has been flavoured by our particular experimental interests and development of mathematical models. We intend the book to be a starting point for academic and industrial scientists beginning research on latex film formation. The emphasis is on fundam- tal mechanisms, however, and not on applications nor on specific effects of formu- tions. We hope that the book consolidates the understanding that has been achieved to-date in the literature in a more comprehensive way than is possible in a review article. We trust that the reader will appreciate the fascination of the topic.
