This book was released on 1998 with total page 173 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'OBJECTIF DE CE TRAVAIL EST D'OBSERVER LE COMPORTEMENT DE MATERIAUX FILTRANTS TRES DIFFERENTS VIS-A-VIS DE CRITERES DONT DEPEND LA QUALITE D'UNE EPURATION BIOLOGIQUE. LES CRITERES RETENUS SONT L'HYDRODYNAMIQUE DU FILTRE INSATURE, LA CAPACITE D'AERATION DES MASSIFS, AINSI QUE LEUR APTITUDE A ELIMINER LES MATIERES EN SUSPENSION. LES MATERIAUX LES MIEUX ADAPTES POUR UNE REDUCTION GEOMETRIQUE DES FILTRES BIOLOGIQUES UTILISES EN ASSAINISSEMENT AUTONOME SONT RECHERCHES. L'ETUDE HYDRODYNAMIQUE DES MATERIAUX REPOSE SUR LA DETERMINATION DE LEUR CAPACITE DE RETENTION DE L'EAU ET LES TEMPS DE SEJOUR MOYENS DANS LE FILTRE. UNE METHODE SYSTEMIQUE A ETE DEVELOPPEE ET PERMET DE CARACTERISER LA QUANTITE TOTALE D'EAU MISE EN JEU DANS UN MASSIF FILTRANT. LA CARACTERISATION DES MASSIFS SUIVANT LEUR CAPACITE D'AERATION CONSISTE A CALCULER LES CONSTANTES DE TRANSFERT PROPRES A CHACUN DES MATERIAUX. DES MODELES TRADUISANT L'EVOLUTION DES CONCENTRATIONS EN OXYGENE DISSOUS EN FONCTION DE LA CHARGE APPLIQUEE ET DE LA HAUTEUR DU MASSIF SONT PROPOSES. L'APTITUDE DES MASSIFS A ELIMINER (RETENTION MECANIQUE-HYDROLYSE) LES MATIERES EN SUSPENSION A ETE ETUDIEE EN UTILISANT DES PARTICULES SYNTHETIQUES (AMIDON INSOLUBLE DE POMME DE TERRE). UNE ETUDE DU MECANISME DE CAPTURE EST EFFECTUEE SUR DEUX MATERIAUX DISTINCTS (SABLE ET SEPIOLITE) ET UN MODELE DE FILTRATION EN PROFONDEUR EST APPLIQUE. IL FAUT NOTER QUE LES CONDITIONS OPERATOIRES RETENUES S'ECARTENT DE CELLES RENCONTREES DANS LA LITTERATURE. UN MODELE GENERAL COUPLANT LA RETENTION MECANIQUE ET LA DEGRADATION BIOLOGIQUE EST PROPOSE ET DES SIMULATIONS NUMERIQUES SONT PRESENTEES. CES CALCULS ONT ETE EFFECTUES EN UTILISANT DES CONSTANTES CINETIQUES D'HYDROLYSE DES PARTICULES DETERMINEES EXPERIMENTALEMENT. CES DIVERSES ETUDES ONT PERMIS DE SELECTIONNER LA SEPIOLITE ET LES DEUX ZEOLITHES (CLINOMIN ET CHABAMIN). L'EPURATION BIOLOGIQUE D'UN EFFLUENT SEPTIQUE MENEE SUR CES MATERIAUX REVELE D'EXCELLENTS RENDEMENTS EPURATOIRES POUR UNE CHARGE DE 5 CM.J#-#1. UNE ELEVATION DE LA CHARGE HYDRAULIQUE EST PRATIQUEE (25 CM.J#-#1) ET MONTRE QUE DE BONNES PERFORMANCES EPURATOIRES SONT CONSERVEES, CE QUI LAISSE PRESAGER QU'UNE REDUCTION GEOMETRIQUE DES FILTRES GARNIS DE CES MATERIAUX EST POSSIBLE.

Download or read book Spaces and Identities in Border Regions written by Christian Wille and published by transcript Verlag. This book was released on 2015-11-30 with total page 385 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spatial and identity research operates with differentiations and relations. These are particularly useful heuristic tools when examining border regions where social and geopolitical demarcations diverge. Applying this approach, the authors of this volume investigate spatial and identity constructions in cross-border contexts as they appear in everyday, institutional and media practices. The results are discussed with a keen eye for obliquely aligned spaces and identities and relinked to governmental issues of normalization and subjectivation. The studies base upon empirical surveys conducted in Germany, France, Belgium and Luxembourg.

Download or read book The Econometrics of Individual Risk written by Christian Gourieroux and published by Princeton University Press. This book was released on 2011-07-24 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: The individual risks faced by banks, insurers, and marketers are less well understood than aggregate risks such as market-price changes. But the risks incurred or carried by individual people, companies, insurance policies, or credit agreements can be just as devastating as macroevents such as share-price fluctuations. A comprehensive introduction, The Econometrics of Individual Risk is the first book to provide a complete econometric methodology for quantifying and managing this underappreciated but important variety of risk. The book presents a course in the econometric theory of individual risk illustrated by empirical examples. And, unlike other texts, it is focused entirely on solving the actual individual risk problems businesses confront today. Christian Gourieroux and Joann Jasiak emphasize the microeconometric aspect of risk analysis by extensively discussing practical problems such as retail credit scoring, credit card transaction dynamics, and profit maximization in promotional mailing. They address regulatory issues in sections on computing the minimum capital reserve for coverage of potential losses, and on the credit-risk measure CreditVar. The book will interest graduate students in economics, business, finance, and actuarial studies, as well as actuaries and financial analysts.

Download or read book Immersion in the Visual Arts and Media written by and published by BRILL. This book was released on 2015-10-27 with total page 401 pages. Available in PDF, EPUB and Kindle. Book excerpt: Taking an interdisciplinary approach, this volume brings together contributions by distinguished experts from different disciplinary fields for a multidimensional view on immersion in the visual arts and media. In the current media debate, immersion has frequently been linked to the advent of digital technology and its capacity to provide vivid sensations of being placed in or surrounded by an artificial space. The idea of ‘liquidity’ contained in this promise to plunge into another world informs wide areas of contemporary cultural imagination, referring to a myriad of phenomena that relate to experiences of uncertainty and instability, of complexity and change. Considering the fact, however, that the idea of ‘liquid’ spaces appeared long before the digital creation of augmented or virtual environments, the contributors to this volume trace its reemerging throughout the history of the visual arts and media. By focusing on selected works of painting and architecture, photography and cinema, video installation and media art, they explore the variability of immersive experiences according to the different media environments and interfaces that constitute the actual sites of historically shifting relations between media and users. Contributors are: Matthias Bauer, Jörg von Brincken, Robin Curtis, Burcu Dogramaci, Thomas Elsaesser, Ole W. Fischer, Gundolf S. Freyermuth, Ursula Frohne, Henry Keazor, Matthias Krüger, Katja Kwastek, Fabienne Liptay, Karl Prümm, Martin Warnke.

Download or read book Historical Dictionary of Pakistan written by Shahid Javed Burki and published by . This book was released on 1999 with total page 472 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pakistan is unlike most other countries in the emerging world. It is one of the two nations – the other being the state of Israel – founded on the basis of religion. Although it was created to provide a homeland for the Muslim community of British India, in its original form it was able to accommodate only about half of the people of Islamic faith who lived in the subcontinent. Pakistan’s birth in 1947 resulted in one of the largest movements of people in human history when some 14 million people left their homes, with 8 million Muslims leaving India for what is now Pakistan and 6 million Hindus and Sikhs moving in the opposite direction. This was the first large-scale incidence of ethnic cleansing the world was to witness. --
