À l’heure où les débats politiques se cristallisent autour du multiculturalisme, de la peur de la mondialisation et des récentes arrivées de migrants, ceci dans une Europe qui développe un repli sur soi, il semble important de redonner une profondeur historique aux échanges de toutes sortes entre les différentes rives de la Méditerranée. La cuisine en tant qu’objet d’analyse montre comment différents pays ont pu s’influencer mutuellement culturellement au point qu’il est difficile aujourd’hui de déterminer exactement l’origine d’une recette. Cependant, il existe toujours des résistances à certains traits culturels de l’Autre et ceci se voit à travers les habitudes alimentaires. Ce travail de recherche étudie les relations gastronomiques entre la France et le Maroc en utilisant le paradigme du transfert culturel. Il montre comment un aliment ou une recette passe ou non les frontières (culturelles et géographiques) et pourquoi. Pour cela, trois contextes ont été définis. La colonisation provoque une des grandes « rencontres » ayant marqué les deux sociétés jusqu’à aujourd’hui. L’alimentation est en effet au cœur des rapports de pouvoir en contexte colonial. Le deuxième facteur de la « rencontre » entre ces deux sociétés est le phénomène migratoire. Après avoir déterminé ses propres stratégies pour se nourrir lui-même en tant qu’individu, le migrant a un rôle dans les transferts culturels gastronomiques entre son pays et la France, notamment lorsque l’on sait que le secteur de l’alimentation est choisi par beaucoup de migrants marocains pour s’installer en France. Le migrant a un rôle d’innovateur en matière gastronomique pendant que l’on voit aussi évoluer les pratiques des sociétés française et européenne au regard de cette migration. En somme, à travers les pratiques alimentaires, les notions d’intégration, d’assimilation et d’acculturation sont réinterrogées. La recherche se termine enfin par une vision d’ensemble qui est celle de la mondialisation et de la volonté politique du Maroc d’utiliser ses ressources d’ordre gastronomique pour se placer sur la scène internationale. / At a time when political debates are crystallizing around multiculturalism, fear of globalization and furthermore the recent arrival of migrants in a Europe which is developing a withdrawal into itself, it seems important to restore some historical depth to the exchanges between the various shores of the Mediterranean area. Food as an object of analysis shows how different countries have so much culturally influenced one another that it is difficult today to determine exactly from where does a recipe comes. However, there is still resistance to certain cultural traits of “the Other” and this is reflected in one’s eating habits. This research studies the gastronomic relations between France and Morocco using the cultural transfer paradigm that shows how recipes could or couldn’t cross borders (in the cultural and geographical meaning) and why. Three context typologies have been defined. Colonization causes one of the great "meetings" that have marked the two societies until today given that in a colonial context food is in the center of power relations. The second factor of the "encounter" between those two societies is the the context of international migration. Migrants and immigrants have a role in cultural gastronomic transfers between their origin country and France, especially because it is chosen by many Moroccan migrants to settle in France by opening restaurants. The migrant has a role of innovator in gastronomic matters while we also see evolving the French and European companies practices towards this migration. Briefly, through eating practices, notions of integration, assimilation and acculturation are re-examined. Finally, the research concludes with an overall vision of globalization and Morocco's political will to use its gastronomic resources to position itself on the international stage.

Bulbuls (Pycnonotidae) are a biologically diverse group of songbirds that produce a variety of vocalisations. Their songs are very audible, yet the vocal behaviour of the majority of bulbul species has not been formally described or subject to bioacoustical study. The Philippine bulbul (Ixos philippinus) is a sedentary and endemic species of the Philippine archipelago. This thesis presents the first detailed descriptions of its song. The songs were recorded on five islands locations that covered eight different habitats. Nine song features of these species were compared, in order to understand song variations between different islands. In searching for correlations, habitat types and geographical distances between the islands were also measured. The songs of the species found on five islands were readily split up into three groups based on end frequency, syllable number and song duration. The correlations possibly relate to a late Pleistocene connection between the islands and colonization routes of the species. It was found that song frequency parameters in bulbul species is primarily affected by habitat, whilst the effect of current distances between islands was shown to be weak.

Artificial ponds are excellent for the study of phytoplankton ecology. They permit repeatable initial conditions and sufficient replication of independent experimental units in complex experiments to test hypotheses about the control of structure and function in natural communities. There were 20 experimental ponds constructed in Kokoř nsko Protected Landscape Area, from which samples were taken and analyzed. This study was part of the EU BIOPOOL. During the first two years after the filling of the ponds the colonization and the seasonal development of phytoplankton communities in the ponds were examined. The phytoplankton species composition was determined, then species richness and relative abundance of individual taxa were quantified. Species composition data were compared with the environmental parameters measured (temperature, oxygen concentration, pH, transparency, conductivity, depth, chlorophyll-a concentration, and zooplankton). In the spring 2007, the ponds were periodic, and followed a similar trend over time (February- April). There were dominated by the following taxonomic groups: Dinophyta, Chrysophyta, Cryptophyta, and Euglenophyta. After installing foil on the bottom of the ponds, the ponds were of permanent character. In terms of environmental parameters, the individual ponds...

Clostridium difficile est une bactérie anaérobie stricte responsable de diarrhées consécutives à une antibiothérapie et de colites pseudomembraneuses. La destruction du microbiote intestinal de barrière favorise l’implantation de C. difficile, qui se multiplie, adhère aux cellules épithéliales et produit les toxines TcdA et TcdB. Les infections à C. difficile sont devenues un problème majeur de santé publique. En particulier les nombreuses rechutes posent un problème thérapeutique. L’immunisation active est une des approches permettant de prévenir les rechutes et réduire l’incidence des infections. Plusieurs essais de vaccination ciblant les toxines sont en cours de développement mais sont sans action sur la première étape de l'infection à C. difficile, la colonisation intestinale. Notre objectif a été de développer une stratégie vaccinale par voie muqueuse pour lutter contre la colonisation intestinale. Des protéines de surface de C. difficile ainsi que la toxine TcdB ayant un rôle dans la pathogénicité ont été sélectionnées et utilisées comme cibles vaccinales. Certains candidats vaccinaux ont été encapsulés afin de pouvoir délivrer les antigènes au niveau de la muqueuse intestinale par voie orale. De plus, pour induire une réponse immunitaire localisée au niveau de la muqueuse intestinale, différents adjuvants ont été testés. Nous avons analysé après vaccination la réponse immunitaire induite au niveau local et systémique. Pour identifier de nouveaux candidats vaccin, le rôle de différentes protéines de surface dans la colonisation intestinale de C. difficile a été caractérisé. L'ensemble des essais in vivo a été mené dans deux modèles animaux de référence pour les infections à C. difficile : la souris et le hamster, pour suivre respectivement la colonisation intestinale par C. difficile et le taux de survie après infection. / Clostridium difficile is an anaerobic bacterium that is responsible for post-antibiotic diarrhea and pseudomembranous colitis. The disruption of the intestinal microbiota barrier effect promotes the establishment of C. difficile, which multiplies, adheres to epithelial cells, and produces the toxins TcdA and TcdB. C. difficile infections are considered as a major public threat. In particular, the multiple recurrences are difficult to treat. Active immunization is one of the new approaches to reduce recurrences and the incidence of these infections. Several vaccine targeting toxins are in development. However, these vaccines have no effect on the first step of C. difficile infection, the host colonization. The objective was to develop a mucosal vaccine strategy to act on intestinal colonization. Surface proteins of C. difficile and TcdB involved in the pathogenicity process were selected and used as vaccine targets. These antigens were produced and encapsulated to deliver them to the intestinal mucosa. Furthermore, to induce a gut mucosal immunity, different adjuvants were tested. After vaccination, we analyzed the local and systemic immune response by immunoassays. Finally, in order to characterize new vaccine candidates, the role of different surface proteins in C. difficile colonization was evaluated. These vaccine trials were conducted in two animal models of reference for C. difficile infections: the mouse and the hamster models, which permit to follow the colonization and the survival rate after infection, respectively.

The Agua Caliente Band of Cahuilla Indians Reservation was established in 1876, the same year as the transcontinental Southern Pacific Railroad completed a station in Palm Springs. These overlapping events would both enable and problematize the settler colonization of the Agua Caliente’s land, creating a checkerboard pattern of “fragmented jurisdiction” that was fundamental for its transformation into one of the wealthiest resorts in the United States. The territorial conflict between the Tribe and the U.S. would only begin to be legally resolved in 1977, when the Agua Caliente won the right to zone and plan their own lands. This dissertation examines how architecture, urbanism, and infrastructure mediated the technical, legal, and ideological struggles that took place in this period; sometimes enabling Imperial dispossession, other times structuring Tribal assimilation and decolonization. The dissertation historicizes and theorizes these processes by examining the modern architecture and urbanism of Palm Springs as a specific settler-colonial, “post-industrial” mode of development which was made possible by the particular territorial configuration that emerged out of nineteenth century Imperialism. It posits a correlation between settler colonialism and the settler imaginaries and material processes of technological progress, capitalist accumulation, natural resource extraction, and cultures of leisure that were uniquely developed in Palm Springs through modern architecture. Critically dismantling the connections between modern architecture, “post-industrial society,” and settler colonialism, this dissertation argues, is a necessary condition for the development of decolonial epistemologies and strategies of anti-colonial, anti-capitalist resistance.

The purpose of this study was to investigate the impact of access roads on the process of spontaneous colonization of virgin forest land in the tropical lowlands of Bolivia. An access road in the Department of Santa Cruz serving an area opened up by spontaneous colonization was studied. The interpretation of aerial photographs and data collected in the area were used to illustrate the importance of access roads for successful spontaneous colonization. General conclusions were drawn with regard to the role that spontaneous colonization as a dynamic force was playing in the development of Bolivia's tropical lowlands.

In form of 3D animation the thesis depicts the steps of mankind towards the expansion of civilization beyond planet Earth. Chronologically it exposes essential moments of technological development (in major) preceding the journey for the distant planets. Images of today's state of civilization are combined with constructions of former theoretical concepts and with fully fictitious elements to form visuals illustrating the roadmap to extraterrestrial expansion.
