Book Description
L'ETUDE DU CHANGEMENT D'ETAT LIQUIDE-SOLIDE D'UNE SOLUTION AQUEUSE D'IODURE DE POTASSIUM ET D'UNE SOLUTION ORGANIQUE DE 1,2 ET 1,4 CHLORONITROBENZENE RETENUES AU SEIN DE CORPS POREUX A ETE REALISEE A L'AIDE DE LA TECHNIQUE DE CALORIMETRIE DIFFERENTIELLE A BALAYAGE. SELON LA PROCEDURE EXPERIMENTALE MISE EN UVRE LORS DU REFROIDISSEMENT, LES SOLUTIONS DONT LA DIVISION EST REALISEE PAR IMPREGNATION DE CORPS POREUX DE TEXTURE CONNUE PEUVENT PRESENTER: SOIT UN COMPORTEMENT METASTABLE: LA RUPTURE DE METASTABILITE ENTRAINE UNE SOLIDIFICATION AVEC RETARD DU MELANGE A L'EXTERIEUR DES PORES ET DU CONDENSAT CAPILLAIRE; SOIT UNE CRISTALLISATION A L'EQUILIBRE: LA SUCCESSION DES TRANSFORMATIONS OBSERVEES INDIQUE QUE LA SOLUTION DANS LES PORES EVOLUE TOUJOURS VERS LA COMPOSITION EUTECTIQUE. LA MIGRATION, DANS SON INTEGRALITE, DU CONSTITUANT EN DEFAUT DANS LES PORES LORS DU REFROIDISSEMENT, CONSTITUE UN MOYEN DE MAITRISER LA COMPOSITION DU CONDENSAT CAPILLAIRE LORSQU'IL COMMENCE A CRISTALLISER. IL A ETE AINSI POSSIBLE D'ETABLIR LE DIAGRAMME DE PHASE DES DEUX MELANGES CONSIDERES, ET RETENUS DANS LES PLUS GROS PORES DE CORPS POREUX DONNES. LES COURBES D'EQUILIBRE OBTENUES, SONT D'ALLURE IDENTIQUE A CELLES DES SOLUTIONS NON DIVISEES ET D'AUTANT PLUS ABAISSEES QUE LA DIVISION DU CONDENSAT CAPILLAIRE EST PLUS IMPORTANTE

Book Description
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 Description
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 Description
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.
