This book was released on 1998 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: LA MODELISATION DU ROLE DES IONS CHLORURES A L'INTERFACE ACIER INOXYDABLE / SOLUTION NECESSITE DE CONNAITRE LA REPARTITION DES CHARGES ET DES POTENTIELS A TRAVERS TOUTE L'INTERFACE. DES MESURES DE SPECTROSCOPIE D'IMPEDANCE ELECTROCHIMIQUE ET DE PHOTOELECTROCHIMIE ONT PERMIS DE CONNAITRE CES REPARTITIONS DANS LE FILM PASSIF. LES MESURES DE POTENTIEL D'ECOULEMENT EFFECTUEES DANS CE TRAVAIL ONT POUR BUT DE PROPOSER DES REPARTITIONS A L'INTERFACE FILM PASSIF / SOLUTION. LES MESURES ONT ETE EFFECTUEES A L'ABANDON, C'EST-A-DIRE SANS IMPOSER DE PERTURBATION ELECTRIQUE EXTERIEURE. DES L'IMMERSION DE L'ACIER EN SOLUTION, IL SE DEVELOPPE ENTRE LE FILM PASSIF DE L'ACIER ET LA SOLUTION UNE INTERPHASE. EN MILIEU NACL, CETTE INTERPHASE EST CONSTITUEE NOTAMMENT DE CATIONS METALLIQUES HYDRATES DU SUBSTRAT ET D'IONS DE L'ELECTROLYTE. LE DEVELOPPEMENT DE L'INTERPHASE, QUI SE FAIT PARALLELEMENT A SON CHARGEMENT EN CHLORURES, EST LIMITANT DURANT LES PREMIERES HEURES D'IMMERSION ET DEPEND, AINSI QUE LES CARACTERISTIQUES DE L'INTERPHASE, DE L'ETAT DE SURFACE DE L'ACIER. L'INTERPHASE PARTICIPE AU SIGNAL DE POTENTIEL D'ECOULEMENT, CONTRAIREMENT A CE QUI EST OBSERVE POUR UN MATERIAU INERTE COMME LE VERRE, QUI NOUS A SERVI DE REFERENCE TOUT AU LONG DE CE TRAVAIL. CETTE PARTICIPATION EST A L'ORIGINE D'UN COMPORTEMENT PARTICULIER DES ACIERS INOXYDABLES VIS-A-VIS DE LA PRESSION IMPOSEE DANS LES MESURES. ICI, NOUS PROPOSONS UNE NOUVELLE METHODE DE CALCUL DU POTENTIEL ZETA QUI PREND EN COMPTE L'EXISTENCE DE CETTE INTERPHASE. NOUS AVONS ETUDIE EGALEMENT LES PROPRIETES ACIDO-BASIQUES DE SURFACE DE DIFFERENTS ETATS DE SURFACE D'ACIERS. LES PH ISOELECTRIQUES DETERMINES VARIENT, SELON L'ETAT DE SURFACE, ENTRE 2 ET 5. ILS SONT PLUS ACIDES QUE LES PH ISOELECTRIQUES DES OXYDES DE FER ET DE CHROME. LES RESULTATS DE MESURES XPS ONT MIS EN EVIDENCE QUE LE RAPPORT CHROME SUR FER DANS LA COUCHE PASSIVE AUGMENTAIT AVEC LE PH ISOELECTRIQUE.

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.
Download or read book First RILEM International Conference on Concrete and Digital Fabrication Digital Concrete 2018 written by Timothy Wangler and published by Springer. This book was released on 2018-08-29 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: Digital fabrication has been termed the “third industrial revolution”, and is promising to revolutionize many disciplines, including most recently the construction sector. Both academia and industry see immense promise in cementitious materials, which lend themselves well to additive manufacturing techniques for digital fabrication in construction. With this recent trend and high interest in this new research field, the 1st RILEM International Conference on Concrete and Digital Fabrication (Digital Concrete 2018) was organized. Since 2014, ETH Zurich has been host for the Swiss National Centre for Competence in Research (NCCR) for Digital Fabrication in Architecture, which is highly interdisciplinary and unique worldwide. In 2018, this NCCR opened the “DFAB House”, which incorporates many digital fabrication principles for architecture. It is also responsible for the 600 m2 Robotic Fabrication Lab and the first robotically built roof in the world. Held in tandem with Rob|Arch 2018, the leading conference for robotics in architecture, RILEM deemed it the right time to combine forces at this new conference, which will be the first large conference to feature the work of the recently created RILEM Technical Committee on Digital Fabrication with Cement-based Materials, among other leaders in this new field worldwide. This conference proceedings brings together papers that take into account the findings in this new area. Papers reflect the varying themes of the conference, including Materials, Processing, Structure, and Applications.

Download or read book Four Laws That Drive the Universe written by Peter Atkins and published by OUP Oxford. This book was released on 2007-09-06 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: The laws of thermodynamics drive everything that happens in the universe. From the sudden expansion of a cloud of gas to the cooling of hot metal, and from the unfurling of a leaf to the course of life itself - everything is directed and constrained by four simple laws. They establish fundamental concepts such as temperature and heat, and reveal the arrow of time and even the nature of energy itself. Peter Atkins' powerful and compelling introduction explains what the laws are and how they work, using accessible language and virtually no mathematics. Guiding the reader from the Zeroth Law to the Third Law, he introduces the fascinating concept of entropy, and how it not only explains why your desk tends to get messier, but also how its unstoppable rise constitutes the engine of the universe.
