Full text

Abstract:

The core of this project was the development of a column flotation dynamic model that can reasonably predict the changes in the concentrations of all solid and bubble species, along the full column height. A dynamic model of a process is normally composed of a set of partial or ordinary differential equations that describe the state of the process at any given time or position inside the system volume. Such equations can be obtained from fundamental material and/or energy balances, or from phenomenological derivations based on knowledge about the behavior of the system. A phenomenological appr

Abstract:

When foundations are designed on weak clay layers, it is a common practice to modify the subgrade by installing stone columns. Currently used methods for determining the level of ground modification, represented by the percentage of soil replaced (replacement ratio), assume a rigid foundation. These analytical methods provide the designer with the potential settlement reduction based on the compressibility parameters of the subgrade and the replacement ratio. The deficiencies of these methods are the assumption of rigidity of the foundation and the consideration of the settlement reduction as

Abstract:

La séparation des C8 aromatiques par Lit Mobile Simulé (LMS) permet d'obtenir du paraxylène (PX) pur. Les autres composés du mélange sont recyclés dans un réacteur afin d'être isomérisés puis séparés à nouveau. La charge du LMS est composée à environ 75% par ce flux de recyclage. L'intégration de la réaction dans le LMS, réalisée en intercalant des réacteurs d'isomérisation entre les lits d'adsorbant de la zone 3 (procédé LMS Réactif, LMSR), doit permettre une réduction de ce flux de recyclage.L'objectif de cette thèse est de développer une méthodologie d'étude des procédés de type Lit Mobile

Abstract:

This thesis proposes two forms of external confinement for concrete filled steel tubular (CFST) columns. The confinement efficiency is studied by examining the axial strength enhancement and ductility improvement of the CFST columns with external confinement. Due to the heavy demand of confining steel to restore the column ductility in seismic regions, it is more efficient to confine these columns by hollow steel tube to form CFST column. Compared with transverse reinforcing steel, steel tube provides a stronger and more uniform confining pressure to the concrete core, and reduces the stee

Cette thèse est une monographie de l'œuvre romanesque de Colson Whitehead (1969– ) replacée dans la perspective de la tradition littéraire noire américaine. Elle pose une question d'ordre esthétique et politique : Whitehead est-il un écrivain postracial ? Dans The Intuitionist (1999), la rivalité entre les personnages noirs et le jeu de masques mettent à mal une politique identitaire qui repose sur la race. La déconstruction du discours mythique qui célèbre le sacrifice d'un travailleur acharné désacralise le héros noir de John Henry Days (2001). Apex Hides the Hurt (2006) offre une réflexion
