Cette thèse s’attache à éclairer un objet peu investigué par la recherche à et sur Djibouti : les liens entre savoir et pouvoir dans un contexte où interagissent tradition pastorale de type nomade et non-tradition sédentaire d’origine coloniale. A partir de constats d’expérience et de l’hypothèse par eux suggérée que savoir et pouvoir ont des liens, elle examine, selon un cadre théorique multiréférentiel (au sens de Jacques Ardoino), et (entre autres sources) par une approche ethnographique précédée d’une démarche exploratoire par entretiens semi-directifs : l’éducation traditionnelle, l’éducation scolaire d’origine coloniale ainsi que l’impact de la scolarisation sur les rapports sociaux traditionnels. Elle met en lumière les configurations éducatives traditionnelles et repère des liens organisés par l’âge entre savoir non-écrit (savoir ancestral) et pouvoir. Elle pointe l’école et ses configurations éducatives où s’acquiert un savoir qui, selon une logique largement déconnectée de l’âge de ses bénéficiaires, confère du pouvoir. Elle montre que, dans le contexte colonial et postcolonial, la scolarisation, par le savoir qu’elle transmet et le pouvoir lié à ce savoir en termes de possibilités, impacte les rapports sociaux traditionnels. En effet, dans l’espace dominant qu’est la ville coloniale puis post-coloniale, les pasteurs autochtones scolarisés se retrouvent en position haute à l’égard de leurs compatriotes non-scolarisés, y compris lorsque ces derniers sont plus âgés qu’eux. C’est, par exemple, le cas à l’endroit de leurs propres parents si ceux-ci n’ont pas fréquenté l’école. Cela crée un renversement de situation par rapport au postulat traditionnel qui veut que le sujet soit plus ‘’sachant’’ que les moins âgés que lui et donc les parents plus ‘’sachants’’ que leurs enfants. Les résultats de la thèse apparaissent plutôt transposables dans des contextes comparables, notamment en Afrique. Enfin, sont repérés dans cette recherche, non sans quelque relation avec l’objet investigué, des phénomènes sociaux à l’oeuvre à Djibouti, et peut-être pas seulement à Djibouti : effets du changement climatique, une montée de la religiosité, une catachrèse des objets et lieux urbains par les pasteurs, une pratique sociale autour de la consommation du khat que nous appelons le khater, ou encore un sentiment de régression qui, en ville comme à la campagne, traverse les lieux de sociabilité. Ce sont là autant de perspectives intéressantes de recherche. / This thesis is aimed at clarifying a topic poorly investigated by research in and on Djibouti: the links between Knowledge and Power in a context where have been interacting nomadic pastoral tradition and non-tradition of colonial origin. From findings of experience and the hypothesis based on them that Knowledge and Power have links, the thesis examines, in a multi-referential theoretical framework (within the meaning of Jacques Ardoino), and (among other sources) through an ethnographic approach preceded by a semi-structured interview-based exploration: Traditional Education, School Education of colonial origin as well as the Impact of the Schooling on the Traditional Social Relations. It brings to light the Traditional Educational Configurations and reveals age-structured Links between non-written Knowledge (Ancestral Knowledge) and Power. It also points at School and its Educational Configurations where is acquired a Knowledge which, in a way widely disconnected from its recipients’ age, gives Power. It shows that, in the colonial and postcolonial context, Schooling, through the Knowledge it gives and the Power linked to this Knowledge in terms of opportunities, impacts Traditional Social Relations. In fact, in the dominant colonial and postcolonial urban area, i.e the town, the schooled pastoralists are in higher position compared to their non-schooled fellow natives, even if the latter are older than them. It’s, for example, the case toward their own parents if these have not attended school. This creates a reversal situation compared to the Traditional Pastoral Assumption that the Individual knows more than those younger than him and so do the parents with regard to their children. The results of the thesis appear rather transferrable into similar contexts, especially in Africa. Finally, are pointed at in this research, in some relation with the topic investigated, social phenomena at work in Djibouti, and perhaps not only in Djibouti: Climate change effects, Rise of religiosity, Catachresis of Urban Items and Places, a Social Practice around the Consumption of Khat that we call the Khating, or a Sense of Regression which is shared in rural and urban Places of Sociability. These are interesting directions of research.

La mondialisation se manifeste comme une évidence ordinaire, à tous les coins de la planète. Comme beaucoup de nos contemporains, nous sommes persuadés de vivre un phénomène complètement inédit. Pour l’historien économiste, parler de mondialisation au singulier reviendrait à ignorer toutes les autres. Il n’est donc pas question ici de nier la vigueur de l’actuelle mondialisation, mais de bien saisir l’ampleur d’un phénomène permanent désormais lié à la conteneurisation. C’est d’ailleurs à la lumière du passé qu’on peut le mieux comprendre les débats actuels et appréhender l’avenir. Mais l’avenir est en grande partie déterminé par un certain nombre de facteurs de changement. S’il n’est pas possible de prédire l’aboutissement final du jeu de ces facteurs, on peut néanmoins spéculer sur la façon dont chacun d’eux peut influer sur l’avenir de l’économie européenne en général, et sur les conséquences qui peuvent en résulter pour la desserte de l’Europe en trafic conteneurisé. Certains de ces facteurs peuvent directement influer sur les points forts et les points faibles des modèles existants ; d’autres peuvent avoir des impacts indirects.Ce travail de thèse se veut un essai dédié à tous les praticiens et universitaires intéressés par le commerce maritime. Ce n’est pas un écrit de certitudes ou bien encore un concentré d’érudition; il ne cherche pas à traiter de tous les aspects du transport maritime et de l’histoire économique de l’Europe. L’Europe, qui ne représente que 7% des terres émergées, est une péninsule bordée de trois cotés par la mer et qui ne dispose sur le quatrième coté d’aucune limite géographique particulièrement nette la séparant du reste du continent eurasiatique. Cette Europe géographique a d’ailleurs rarement coïncidé avec l’Europe économique. Il faut, en effet, considérer que la vaste région d’Europe de l’est et du Sud-est fut envahie et asservie par des conquérants non européens, dont elle ne fut libérée qu’au bout de plusieurs siècles. En fait, l’Europe a toujours été à géométrie variable, ce qui est normal, car elle est une résultante depuis les temps antiques de toutes les invasions et de tous les échanges eurasiatiques. Après la découverte des Amériques, les Européens ont développé le commerce à l’échelle de la planète et imposé leur hégémonie jusqu’en 1914. Aux épices et autres objets orientaux, se sont ajoutés les produits des « Indes occidentales». Cette position centrale, acquise grâce à une supériorité démographique et technique procède d’un double impérialisme économique et centralisateur d’abord contesté au début du 20ème siècle et aujourd’hui largement condamné. Avec d’énormes capacités de transport et de très bas coûts, la conteneurisation accompagne depuis plus de cinquante ans la mondialisation et a totalement révolutionnée le transport de lignes régulières des marchandises diverses. Dès lors, une question permanente touchant à la globalisation des échanges et à la navigation vient se poser sous différentes formes dans cette thèse à savoir l’accès au marché mondial de L’Europe lié assurément à la performance des infrastructures de l’Europe mais plus encore à la circulation planétaire. L’avenir de l’Europe passe inéluctablement par la Méditerranée et il est contrarié par un « effet de ciseau » mettant en péril l’insertion des pays du sud de cette Méditerranée dans le processus de mondialisation. L’Europe a un rôle majeur à jouer dans cette région mais elle ne fait rien ou presque face à l’émergence des puissances asiatiques et latino-américaines. Si l’on attend qu’elle ait trouvé son «chemin de Damas», le risque est évident de voir à l’horizon 2030 disparaître la position centrale de l’Europe. Inversement, une projection raisonnable laisse prévoir un système global de commerce et de navigation centré sur l’océan Indien et les mers de Chine, les flux de trafics européens devenant graduellement périphériques dans une nouvelle circulation planétaire. / Throughout the world globalisation exists as an everyday reality. Like many of our contemporaries, we are convinced that we are experiencing a completely new phenomenon. For the economic historian, talking about globalisation in the singular would mean ignoring all the others. It is not the purpose of this essay to deny the vigour of the current globalisation, but to grasp the size of a permanent phenomenon, which is now linked to containerisation. In fact, with the benefit of hindsight and a study of the past, we can understand better the current debates and possible future developments. But the future is largely determined by a certain number of change factors. If it is not possible to predict the final outcome of these changes, nonetheless, we can speculate on the way each might influence the future of the European economy, in general, and on the consequences which can result from the provision of containerised transport throughout Europe. Some of these factors can directly influence the strengths and weaknesses of the existing models; others can have indirect impacts.This thesis is an essay which is aimed at all the practitioners and university specialists interested in maritime trade. It is not a text about certitudes, nor a piece of condensed scholarship; the objective is neither to cover every aspect of maritime transport nor the economic history of Europe. Europe, which only represents 7% of the global land mass, is a peninsula bordered on three sides by the seas and does not have a neat geographical border on the fourth side separating it from the rest of the Eurasian continent. This geographical Europe has rarely coincided with an economic Europe. We must consider that the vast regions of east and south-east Europe were invaded and enslaved by non-European conquerors, and were liberated only after many centuries. In fact Europe has always had a variable geometry, which is normal, because, since ancient times it has been the result of all the different invasions and Eurasian trade. After the discovery of the American continent, Europeans developed commerce on a worldwide scale and imposed their hegemony until 1914. Spices and other oriental products were added to the products from the “East Indies”. This central position, obtained because of a demographic and technical superiority, stems from an economic and centralizing imperialism, challenged at the start of the 20th century and today largely condemned.With enormous transport capacities and very low costs, containerisation has accompanied globalisation for more than fifty years and has totally revolutionised the transport on regular lines of different merchandise. Henceforth, a permanent question about the globalisation of trade and navigation appears in different forms in this thesis; this is that access to the global market of Europe is certainly linked to the performance of European infrastructure but even more to global traffic. The future of Europe is inevitably linked to the Mediterranean and is thwarted by the “price scissors effect” which puts at risk the involvement of southern Mediterranean states in the process of globalisation. Europe has a major role to play in this region, but it does nearly nothing in response to the emergence of Asian and Latin American powers. If we wait for Europe to find its “road to Damascus”, there is a risk that by 2030 it will have lost its central role. On the other hand a reasonable prediction is that there will be a global system of trade and navigation centred on the Indian Ocean and the China seas, while European traffic gradually becomes peripheral to a new global containerised transport circulation.

Além disso, pode-se verificar a partir do estudo de utilização desse tipo de tecnologia no mundo que existe uma tendência e perspectiva de utilização crescente nos Sistemas Elétricos de Potência. Desta forma, torna-se cada vez mais importante dispor de técnicas que possibilitem a inclusão dos modelos destes equipamentos em programas de análise de redes de forma eficiente, principalmente no fluxo de potência, com a finalidade de permitir a correta modelagem da rede como um todo nos estudos de planejamento da expansão e operação. A transmissão em corrente contínua vem se tornando amplamente reconhecida no que tange as suas vantagens no transporte de grandes blocos de energia a grandes distâncias, no transporte de potência entre parques eólicos offshore para terra, na interconexão de sistemas com frequências não compatíveis, em travessias subaquáticas, dentre outras questões que a tornam técnica e economicamente viável em algumas situações. Nesse contexto, este trabalho tem por principal objetivo desenvolver e implementar uma metodologia genérica para a representação de Sistemas de Transmissão HVDC Multiterminais no problema de fluxo de potência. Neste sentido, tal metodologia é baseada na solução simultânea de um sistema de equações não lineares composto pelas representações em regime permanente das redes C.C. e C.A., utilizando-se o método de Newton-Raphson para sua solução. A partir deste contexto, são apresentadas as equações que representam a resposta de regime permanente dos conversores, da rede C.C. e das estratégias de controle aplicáveis a esses sistemas. Além disso, são apresentadas as principais configurações existentes de conversores HVDC, suas características e como é feita sua modelagem em regime permanente e no problema de Fluxo de Potência. A metodologia proposta é validada através do estudo de sistemas tutoriais e sistemas teste encontrados como referência na literatura especializada. Os resultados apresentados demonstram que a metodologia proposta é capaz de representar de forma satisfatória os modelos de sistemas HVDC Multiterminais nos estudos de regime permanente em Sistemas Elétricos de Potência. / High Voltage Direct Current (HVDC) technology has characteristics that make it especially attractive for certain transmission applications. Furthermore, it is possible to notice that there is a trend and prospect of increased use of this technology in Electric Power Systems around the world. In this context, it has been increasingly important to have techniques that efficiently include these equipment models in network analysis programs, especially in power flow, in order to allow a correct modeling of the network in studies of expansion planning and operation. The direct current transmission is becoming widely recognized by their advantages in transporting large blocks of power over long distances, to transport power from offshore wind farms to land, in asynchronous interconnection of systems, in underwater crossings, and other issues that make it technically and economically feasible in some situations. In this context, this thesis has the objective to develop and implement a generic methodology for the representation of HVDC Multi-Terminal Systems in the power flow problem. In this sense, this methodology is based on the simultaneous solution of a system of nonlinear equations that represent, in steady state studies, the DC and AC networks, using the Newton-Raphson method to solve the problem. Equations that represent the steady state response of the converters, the DC network and control strategies are presented. In addition, it will be presented the main settings of HVDC converters, their characteristics and how their modelling are set forth in the Power Flow problem. The proposed methodology is validated by studying tutorial and test systems found in the literature. The results show that the proposed methodology is able to represent satisfactorily models of HVDC Multi-Terminal Systems in studies of steady state in Electric Power Systems.

Le développement de systèmes IRM à plus haut champ magnétique statique s'est accompagné d'une interrogation légitime concernant l'effet des champs électromagnétiques RF sur les patients. L'effet peut être renforcé par l'introduction d'éléments conducteurs à l'intérieur de la bobine RF comme c'est le cas pour les capteurs endoluminaux utilisés pour l'analyse des parois digestives. Ces capteurs entraînent des risques d'échauffements locaux élevés pour le patient en raison du TAS local induit par le champ électrique RF en présence d'un fil conducteur. Ces capteurs ayant le potentiel de présenter un bénéfice pour le patient, il est nécessaire de s'affranchir de ces limitations. Le premier objectif de la thèse est le développement d'un capteur endoluminal à liaisons optiques. Un dispositif de découplage actif optique a été développé et caractérisé. Les images RMN in vitro montrent une distribution du RSB comparable au découplage classique, validant ainsi l'efficacité du découplage optique. Concernant la transmission optique du signal RMN, des travaux ont été réalisés afin de s'affranchir des contraintes liées à l'utilisation d'un guide d'onde pour la conversion électro-optique par effet Pockels. Le capteur a été rendu plus compact. En revanche, l'importance de contrôler le TAS local dans des conditions expérimentales données demeure un besoin ne s'arrêtant pas à ceux des capteurs endoluminaux. Le second objectif est donc la validation expérimentale d'une sonde électro-optique pour la mesure du champ électrique RF durant un examen IRM. Cette sonde a permis d'effectuer des mesures du champ électrique dans l'air et dans différents milieux biologiques à 3 T et 4,7 T et estimer le TAS local / The recent advancement in MRI systems and the increase of the static magnetic field strength were accompanied by a strong concern about the effect of RF electromagnetic fields on patients. The effect can be increased by the use of conductive elements inside the volume coil as in the case of endoluminal coils used to analyze digestive walls. These coils lead to an increase of the local SAR which is induced by RF electric field in the presence of the coaxial cable connecting the coil to the MR system, resulting in strong local heating. Giving that these coils have the potential to present a real benefit to the patient, it worth to overcome these limitations. Accordingly, the first objective of the thesis is the development of a fully optical endoluminal receiver coil. An optical active detuning system has been developed and characterized. The NMR images show a signal-to-noise ratio distribution similar to that obtained with conventional detuning techniques, thus validating the efficiency of the optical detuning. Concerning the electro-optical conversion and the optical transmission of the NMR signal, experiments were performed to overcome constraints related to the use of waveguide for electro-optical conversion by Pockels effect. Moreover, the importance of monitoring global and local SAR during MRI exams remains a need which is not limited only to the endoluminal coils. The second objective of the thesis is then the experimental validation of an electro-optical probe for real-time measurements of RF electric field. This probe can measure the RF electric field in air and in biological media at 3 T and 4.7 T MRI systems and allows the estimation of the local SAR

Chronic posterior compartment syndrome (CPCS) of the leg is a pathological condition which is often encountered by participants in exercise related activities such as running. To date no successful conservative treatment approach existed for the condition. The mainstay of the management of the condition at present is the surgical release of the involved fascia that surrounds the compartment. The main aim of the research project was thus to develop a successful conservative treatment approach for the symptoms of CPCS. It was identified that the current theoretical base did not incorporate the continuous and relatively inelastic nature of the fascia which plays an important role in the condition. Based on an extended literature review, muscles which are linked to the posterior compartment via the myofascial tissue were identified. Tightness in these clinically significant muscles is able to induce stresses in the myofascial chain which could ultimately influence stresses in the posterior compartment of the leg. The release of tightness in these muscles external to the posterior compartment through soft tissue mobilization techniques provides an effective conservative treatment approach for the symptoms of CPCS. A revised model for the pathogenesis of CPCS was developed which formed the basis for treatment interventions. The revised theoretical model for the pathogenesis of CPCS was validated based on a mixed-methodological approach which included a series of exploratory as well as explanatory case studies. This qualitative approach was supplemented by quantitative experiments in which the causal relationships of the condition on certain biomechanical aspects were explored. The treatment interventions had a hundred percent success rate and the results of the experimental research conducted also supports the new theoretical model for the pathogenesis of CPCS. / Thesis (DPhil)--University of Pretoria, 2008. / Biokinetics, Sport and Leisure Sciences / unrestricted

First appearing on potsherds around 3300 BC, the Indus script was primarily in use during the Mature Harappan period (ca. 2600-1900 BC) in the Indus Valley region, centred in the north-western region of the Indian Subcontinent. It is one of the last remaining undeciphered scripts of the ancient world. A great number of Indus inscriptions, however, have been uncovered at many archaeological sites in the Persian Gulf, discoveries that corroborate the inclusion of the Indus civilization as an active participant in the Mesopotamian-dominated Gulf trade of the 3rd millennium. In addition to exploring the current state of research surrounding the Indus decipherment attempts, the thesis will examine new perspectives on ancient history, arguing in favour of various possibilities of Mesopotamian, Elamite, and/or pre-dynastic Egyptian (North East African) cultural presences or influences in the ancient Indus River basin.

This work deals with studying a molecular mechanism of anticancer effect of a new platinum - based drug. The qualities of still unknow dinuclear platinum komplex (BBR3571-DACH) were parallelly studied together with clinically time-tested and used mononuclear platinum complex DACH. Earlier essays demostrated, that DNA is the critical target for the cytostatic activity of platinum compounds. Altered properties of DNA and binding characteristics of these two platinum compounds were monitored by several different bioanalytical methods (differential pulse polarography, UV-VIS spectrophotometry, fluorescence spectrophotometry, CD spectroscopy and electrophoresis) after modification of DNA by both of platinum complexes. For the compounds BBR3571-DACH and DACH it was determined that the DNA binding is rapid and bifunctional. The stabilizing effect on DNA was significant particularly after modification of DNA by dinuclear komplex, while denaturating effect wasn´t proved at all. The results also indicate that dinuclear platinum complex BBR3571-DACH probably does not participate on formation of long-range cross-links like other early studied polynuclear platinum complexes.
