Book excerpt: NOUS AVONS ENTREPRIS UNE ETUDE SYSTEMATIQUE SUR LE COMPORTEMENT RHEOLOGIQUE, LA PERCOLATION ET L'ENDOMMAGEMENT DE MATERIAUX CONTENANT LA PHASE INTERGRANULAIRE EUTECTIQUE. CETTE ETUDE A ETE REALISEE A DES TEMPERATURES ENGLOBANT LA TEMPERATURE DE FUSION DE LA PHASE EUTECTIQUE EN VUE D'OBTENIR DEUX TYPES DE JOINTS: SOLIDE OU LIQUIDE. TOUT AU LONG DE CETTE ETUDE, NOUS NOUS SOMMES ATTACHES A COMPARER LE COMPORTEMENT DU MATERIAU A JOINTS SOLIDES VISQUEUX A CELUI DU MATERIAU A JOINTS LIQUIDES. UN MODELE MORPHOLOGIQUE DES GRAINS AVEC DES POCHES LIQUIDES A ETE PROPOSE, CE QUI PERMET DE DETERMINER LA FRACTION VOLUMIQUE DE L'INTERPHASE. LE COMPORTEMENT DU MATERIAU PEUT ETRE PRESENTE DANS UN DIAGRAMME DE TYPE ASHBY EN PRENANT EN COMPTE LA NATURE DES JOINTS DE GRAINS. LE MECANISME DE DISSOLUTION-DIFFUSION-PRECIPITATION DU A LA CONTRAINTE NORMALE EST IMPORTANT LORSQUE L'INTERPHASE EST LIQUIDE. CECI PROVOQUE UNE CROISSANCE DE LA SURFACE DES CONTACTS ENTRE LES GRAINS LORS DES ESSAIS EN COMPRESSION, NOTAMMENT EN COMPRESSION TRIAXIALE. L'ETUDE DE LA PERCOLATION DE LA PHASE INTERGRANULAIRE MONTRE QUE CETTE PERCOLATION EST PROVOQUEE PAR LE GRADIENT DE LA CONTRAINTE LOCALE ET DEPEND DE LA VISCOSITE DE L'INTERPHASE. L'ENDOMMAGEMENT SE PRODUIT DANS LES JOINTS SOLIDES VISQUEUX OU LIQUIDES ET DEPEND DE LA CONTRAINTE LOCALE EN TRACTION S'EXERCANT SUR CES JOINTS. CETTE CONTRAINTE EN TRACTION PEUT ETRE COMPENSEE PAR LA PRESSION EFFECTIVE AU COURS DE DEFORMATION EN COMPRESSION TRIAXIALE, CE QUI REDUIT L'ENDOMMAGEMENT. COMME LA PERCOLATION EST UN MECANISME D'ACCOMODATION, MOINS IL Y A DE LIQUIDE, PLUS LA PERCOLATION EST DIFFICILE ET PLUS L'ENDOMMAGEMENT EST IMPORTANT

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 excerpt: This publication results from a technical meeting on phenomenology and technologies relevant to in-vessel melt retention (IVMR) and ex-vessel corium cooling (EVCC). The purpose of the publication is to capture the state of knowledge, at the time of that meeting, related to phenomenology and technologies as well as the challenges and pending issues relevant to IVMR and EVCC for water cooled reactors by summarizing the information provided by the meeting participants in a form useful to practitioners in Member States.

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.
