Le travail effectué dans ce mémoire se situe dans le cadre de l'étude des transferts dans les sols non saturés. On porte une attention particulière au phénomène de dissolution d'un constituant gazeux dans l'eau d'un sol. A prés avoir fait l'état de la question dans la partie I, on élabore dans la partie II un modèle mathématique des transferts dans un sol non saturé. Ce modèle, basé sur la Mécanique des milieux hétérogènes et la Thermodynamique des Processus Irréversibles Linéaire, permet d'établir la relation phénoménologique de dissolution d'un constituant gazeux dans l'eau d'un sol. La partie III est consacrée à la vérification expérimentale de la relation de dissolution établie dans la partie II et à la mesure du coefficient phénoménologique de dissolution dans le cas du bromure de méthyle. Les matériaux utilisés sont pour ces expériences une porcelaine poreuse et une argile frittée partiellement saturées. La partie IV est consacrée à l'étude numérique de la pénétration par diffusion gazeuse et de la fixation paar dissolution du bromure de méthyle dans une colonne de sol.

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.

This dual-language dictionary lists over 20,000 specialist terms in both French and English, covering architecture, building, engineering and property terms. It meets the needs of all building professionals working on projects overseas. It has been comprehensively researched and compiled to provide an invaluable reference source in an increasingly European marketplace.

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.

Trade can dramatically improve women’s lives, creating new jobs, enhancing consumer choices, and increasing women’s bargaining power in society. It can also lead to job losses and a concentration of work in low-skilled employment. Given the complexity and specificity of the relationship between trade and gender, it is essential to assess the potential impact of trade policy on both women and men and to develop appropriate, evidence-based policies to ensure that trade helps to enhance opportunities for all. Research on gender equality and trade has been constrained by limited data and a lack of understanding of the connections among the economic roles that women play as workers, consumers, and decision makers. Building on new analyses and new sex-disaggregated data, Women and Trade: The Role of Trade in Promoting Gender Equality aims to advance the understanding of the relationship between trade and gender equality and to identify a series of opportunities through which trade can improve the lives of women.
