Book Description
L'objectif de cette thèse est d'élargir les connaissances des propriétés thermophysiques et thermodynamiques des liquides ioniques ainsi que leurs mélanges avec d'autres fluides. Sept liquides ioniques ont été sélectionnés -le1- butyl-3- méthylimidazolium tetrafluoroborate, le 1-butyl-3- méthylimidazolium hexofluorophosphate, le 1-butyl-3-méthylimidazolium bis (trifluorométhylsulfonyl)imide, le 1-éthyl-3-méthylimidazolium bis(trifluorométhylsulfonyl)imide, le triméthyl- butylammonium bis(trifluorométhylsulfonyl)imide, le 1-éthyl-3-méthulimidazolium éthylsulfatee et le butyl-méthylpyrrolidinium bis(trifluorométhylsulfonyl)imide- afin d'étudier l'impact du cation et de l'anion sur les propriétés mesurées. La première des mesures réalisées a été consacrée à l'étude thermophysique (masse volumique et viscosité) des liquides ioniques et de leurs mélanges avec l'eau en fonction de la température comprise entre 293 et 423 K et de la composition à pression atmosphérique. L'étude de la masse volumique des liquides ioniques purs s'est poursuivie en fonction de la pression jusqu'à 40 MPa, ce qui a permis d'accéder à leurs coefficients mécaniques. La deuxième étape de mesure a consisté en l'étude des propriétés thermodynamiques d'équilibres entre phase associant un liquide ionique à un autre fluide.Tout d'abord la solubilité de huit gaz - le dioxyde de carbone, l'éthane, le méthane, l'azote, l'oxygène, l'argon, l'hydrogène et le monoxyde de carbone - a été étudiée expérimentalement dans des liquides ioniques en fonction de la température comprise entre 283 et 343 K avec des pressions proche de l'atmosphérique. Finalement, la miscibilité des liquides ioniques avec l'eau et avec trois alcools - le hexan-1-ol , le hexan-1,2-diol et le cyclohexanol - a été déterminée à différentes températures

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.

Book Description
Until recently, the chemical industry has been dominated by the manufacture of bulk commodity chemicals such as benzene, ammonia, and polypropylene. However, over the last decade a significant shift occurred. Now most chemical companies devote any new resources to the design and manufacture of specialty, high value-added chemical products such as pharmaceuticals, cosmetics, and electronic coatings. Although the jobs held by chemical engineers have also changed to reflect this altered business, their training has remained static, emphasizing traditional commodities. This ground-breaking text starts to redress the balance between commodities and higher value-added products. It expands the scope of chemical engineering design to encompass both process design and product design. The authors use a four-step procedure for chemical product design - needs, ideas, selection, manufacture - drawing numerous examples from industry to illustrate the discussion. The book concludes with a brief review of the economic issues. Chemical engineering students and beginning chemical engineers will find this text an inviting introduction to chemical product design.

Book Description
"Dietary fibre is of interest to both science and industry, and yet despite growing awareness of its benefits to health and nutrition, intakes remain below the recommended level. Industry has responded by developing new applications, products and processes to help consumers increase their fibre intake in a convenient way. While regulations on health claims are being developed for example in the EU, some countries have allowed the use of health claims to help promote consumer awareness of the benefits of a higher fibre intake, and to inform consumers of good sources of fibre. At the same time science is developing the concept of dietary fibre. The mechanisms and actual components behind the physiological effects are of particular interest, and so are the analytical tools to measure these. The fate of dietary fibre in the gut, where certain fibre components are fermented and converted by microbes gains a great deal of attention. The role of molecular weight and viscosity of dietary fibre components in determining the health benefits are also discussed. This book is essential reading for all researchers and those who concern themselves with bioprocesses and food technology. 'Dietary fibre components and functions' covers the most up-to-date research available on dietary fibre and will be an indispensable tool for all scientists involved in research and development in this field."
