A qui appartiennent les espaces publics ? Les visions contemporaines de la gouvernance s’accordent sur l’importance de développer chez les citoyens le sens des responsabilités à l’égard de ce qui nous est commun. En matière d’espaces publics, et en référence aux travaux d’H. Gardner sur les intelligences multiples, ce sens des responsabilités mis en actes pourrait témoigner d’une intelligence commune du territoire, dont cette fiche présente quelques caractéristiques.

Le mémoire concerne l’étude de l’hydrodynamique des écoulements dans des lits fixes parcourus par un écoulement à contre courant de gaz et de liquide. Il est plus particulièrement consacré à l’analyse par tomographie à rayons X de la distribution spatiale des phases liquide et solide dans des empilages de distillation et de distillation réactive. Le principe de la distillation réactive est de réaliser, dans une même colonne, une réaction chimique exothermique et la séparation des produits par distillation. L’industrie chimique marque beaucoup d’intérêt pour ce type d’appareil en raison des nombreux avantages qu’il offre : une réduction des investissements, puisqu’un seul appareil est utilisé au lieu de deux ; une très grande intégration énergétique des étapes de réaction et de séparation, puisque la chaleur générée par la réaction est directement utilisée pour la distillation ; la possibilité d'augmenter la conversion dans le cas des réactions limitées à l'équilibre ; … Les empilages utilisés en distillation réactive présentent généralement une structure modulaire. Chaque élément comporte une ou plusieurs zones catalytiques, dans lesquelles la réaction se déroule et une ou plusieurs zones de séparation, où la distillation peut être réalisée. Vu la structure extrêmement complexe de ces empilages, la compréhension et la description des écoulements en leur sein sont des tâches particulièrement ardues que très peu d’équipes de recherches ont entamées jusqu’à présent. Le but du présent travail de thèse est de collecter une information expérimentale aussi précise et aussi complète que possible, permettant de déterminer les mécanismes hydrodynamiques qui interviennent dans les empilages de distillation réactive. La tomographie à rayons X est utilisée pour mesurer la distribution des phases à différentes échelles, depuis l’échelle locale des détails de l’empilage, jusqu’à l’échelle de la colonne dans son ensemble. Les résultats obtenus permettent non seulement de quantifier les grandeurs hydrodynamiques macroscopiques comme la rétention ou l’aire interfaciale mais, ils permettent également et surtout d’expliquer leur évolution en fonction de la structure de l’empilage et des conditions opératoires.

The European transport policy has focused on sustainable transport solutions. One of its objectives for freight transport is to restore the balance between modes and to develop intermodality. Among the various types of intermodal transports, this research is concerned with rail-road container terminals embedded in a hub-and–spoke network. These terminals will further be referred to as hubs. Hub-and-spoke networks have been implemented in a number of transportation systems when it is favourable to consolidate and disseminate flows at certain locations called hubs. The efficiency of such a network depends on the location of the hubs. The problem is to find the optimal hub locations and to allocate the remaining nodes to these hubs. This problem is known as the p-hub median problem (p-HMP) where p is the number of hubs to locate. This location-allocation problem is proved to be NP-hard. The time needed to solve it increases as the number of nodes exponent three. Thus, in order to model rail-road transport on the trans-European networks, a subset of nodes that can be considered as good potential locations is needed. We applied the p-HMP to a set of potential locations obtained by both spatial aggregation of demand nodes using hierarchical clustering methods and by a flow-based approach which takes the flows of commodities and their geographic spread into account. They showed that the latest method gives better results and that is why it is retained to determine a set of potential locations. The set of potential locations is used as input for an iterative procedure. One of the main contributions of this research is to propose this iterative procedure based on both the p-HMP and the multi-modal assignment problem. Moreover, the objective function of our p-hub median formulation includes the costs for pre- and post-haulages by road, trans-shipment (according to the number of handled containers into account) and rail haulage. Furthermore, in the p-hub median problem, the total demand is assigned to the hubs. In this research however, the demand can be assigned over all the transportation modes, with the possibility (but not the obligation) of using the trans-shipment facilities. Finally, we presents a methodology able to compare road and rail-road intermodal market areas that takes the network structures, the operation costs and the location of the rail-road terminals into account. This methodology is applied to the optimal configurations obtained by the resolution of the p-HMP and the p-hub centre problem (p-HCP) for the whole trans-European network. Indeed, p-HMP has an efficiency goal by minimizing the total transportation cost. The hub network design obtained by this method can sometimes lead to unsatisfactory results when worst-case origin-destination pairs are separated by a very large distance. Therefore, the p-HCM meets the equity objective by minimizing the maximum cost of a combined transport. [less ▲]

L’insuffisance cardiaque (IC) et celle frappant les reins (IR) constituent deux pathologies au sommet d’un iceberg, cachant un grand nombre de candidats à ces complications redoutables. Souvent, trois facteurs de risque sont retrouvés très précocement dans l’histoire de ces patients, à savoir l’hypertension artérielle, le diabète sucré et le vieillissement. [less ▲]

At present, sensory evaluation is not yet integrated in all labels and standards. After comparison and interpretation of the weaknesses and the strengths of the several existing methods, a methodology has been elaborated. Previous experience in off-odour measurements for environmental field investigations help us to propose a methodology based on the assessment of odour intensity and hedonic tone. Various floor covering materials were tested in the lab with a self-made instrument. The sampling procedure is based on a "Field and Laboratory Emission Cell" (FLEC). The odour of the material is compared to a 8-level butanol intensity scale generated through a vaporization chamber and 8 stainless steel capillaries distributing the diluted n-butanol to 8 sniffing ports. First results shows generally a correlation between bad hedonic tone and odour intensity. On the contrary, there are no systematic relations between VOC levels and odour perception. The less odorous materials (PVC) are also the ones with the higher level of total VOC and the linoleum had a strong odour with a low level of total VOC. The explanation lies in the chemical family composition of the emission. The PVC emission contains mainly alkanes compounds (non odorous family) whereas the linoleum contains also odorous chemical families like carboxylic acids and aldehydes. [less ▲]

This research aims to explain and understand the organisational diversity observed in the field of Fair Trade Social Enterprises or Fair Trade Organisations (FTOs). The transversal hypothesis is that such a diversity in organisational forms may be linked to the multidimensional (economic, social and/or political) nature of Fair Trade. First, since there are virtually no typologies focused on FTOs, it is necessary to look at how organisational diversity in FT can be categorised. A typology with five categories of organisational forms is suggested. Secondly, this work explores the reasons behind organisational diversity, using both an external, explanatory perspective, and an internal, interactionist perspective. A third key issue is to explore whether FTOs experience tensions between the different dimensions of FT, and how these tensions are managed in the different types of FTOs. These issues are examined under the light of different theoretical approaches linked to “new institutionalism” (economic, sociological and entrepreneurial) and resource dependence theory. The empirical material is provided by interviews with the leaders of 57 FTOs in four European regions: Belgium, France (Rhône-Alpes), the United Kingdom (England) and Italy (Rome). Eight of these FTOs, reflecting the different categories of organisational forms, are analysed more in depth. [less ▲]

The genetic diversity among Tunisian pomegranate cultivars has been investigated. Using universal primers, the random amplified polymorphic DNA (RAPD) method was used to generate banding profiles from a set of twelve cultivars. Data was then computed with appropriate programs to construct a dendrogram illustrating the relationships between the studied cultivars. Our data proved the efficiency of the designed method to examine the DNA polymorphism in this crop since the tested primers are characterized by a collective resolving power of 12.83. In addition, the cluster analysis has exhibited a parsimonious tree branching independent from the geographic origin of the cultivars. In spite of the relatively low number of primers and cultivars, RAPD constitutes an appropriate procedure to assess the genetic diversity and to survey the phylogenetic relationships in this crop.
