Texte intégralThis thesis dissertation provides a summary of the place and evolution of lithic industries in northern France, between the 3rd millennium and the first half of the 2nd millennium BC. This work is based on research carried out for twenty-five years in the Nord, Pas-de-Calais and Somme and is based on some thirty series bringing together more than 70,000 objects in siliceous materials from sites attributed to the Deûle-Escaut, the Bell Beaker and the Early Bronze Age. Beyond the techno-functional characterization of the stone industries from the Late Neolithic and the beginning of the Bronze Age, this work addresses the place and the role - utilitarian as well as symbolic - occupied by this technical subsystem and its evolution, in a context marked by the development of metallurgy. Evolutionary trends are defined from the components specific to each lithic series and from the analysis of common features and discriminating traits. The dynamic reading of the methods of acquisition, manufacture and consumption of stone tools is made possible by approaching the operating processes (technical and functional) from a global point of view and by varying the scales. A change in the status of the lithic industry marks the transition to a new tradition from the onset of the Bronze Age. This cultural technology approach aims, beyond the study of the object per se, to reveal the society that produced it by attempting to establish relationships between technical phenomena and socio-cultural phenomena. The conditions for change, continuity and rupture are questioned; hypotheses and interpretations are proposed by seeking insights beyond the limits specific to material documentation
Lebeau, Boris. « L' intercommunalité francilienne : le cas nord parisien ». Paris 13, 2006. http://www.theses.fr/2006PA131021.
Texte intégralAfter ten years of an unprecedented development of intercommunlity with is own tax system in Ile-de-France, a question is raised, i. E. The ability of that new institutional network to make the management of the metropolitan area more rational. Subordinated to the political decisions of the elected representatives in charge of its implementation and competing with the more standard institutional players, intercommunality struggles to assert itself as a relevant frame public policy. Far from confining itself to an inventory of the shortcomings of governance in Ile-de-France, this thesis also insists on a core problem facing a geographer: is it possible or not to provide a system of administrative division both coherent and efficient in a metropolitan area of such a large dimension? We will both use geographical concepts (of territory, boundary, discontinuity) and minutely analyse the political, economic, social and territorial aspects of intercommunality in order to emphasize that the different territories of the city are always changing. The geographical point of view therefore suggests that functional and institutional territories can only be partially consistent with each other and that beyond intercommunality some paradigms of urban development probably have to be rethought

Texte intégralTaking into consideration the fact that the complex and tragic characteristic of the North-Transylvanian Holocaust can only be expressed through a systematic and impartial research of both written sources and the live testimonies of those who lived this history, the purpose of the present work is, by using the methodology of oral history, to offer an image of the individual and collective Jewish life in the period before and during World War II, as well as that occurred after the returning from the concentration camps. The research campaign comprised the northern-Transylvanian counties affected by the Holocaust. The present study is a reference work, because the interviewees are direct victims of the Nazi extermination politics as well as various witnesses, Hungarian or Romanian, who were part of the historical evolution

Bloqueadores de Canal de Cálcio (BCC) representam um grupo de agentes terapêuticos utilizados no tratamento de problemas cardiovasculares, incluindo hipertensão e angina. Todos esses fármacos agem como antagonistas dos canais de cálcio que são responsáveis pela ativação dos músculos cardíaco e liso vascular. Teoricamente, várias técnicas de Relação Estrutura-Atividade (SAR) têm sido usadas para propor novas drogas. O objetivo de presente trabalho é o estudo teórico da relação estrutura-atividade para BCC – derivados do oxadiazol-3-ona – utilizados em tratamento de doenças cardiovasculares. Estudos anteriores têm mostrado uma melhor atividade farmacológica para a série de 8-aril-8-hidroxil-5-metil-8H-[1,4] tiazino [3,4-c] [1,2,4] oxadiazol-3-ona, quando comparado ao conhecido bloqueador de entrada de cálcio tipo L Diltiazem. Neste trabalho, utilizou-se a Metodologia dos Índices Eletrônicos (MIE) na investigação sistemática de uma série de moléculas proposta na literatura. Este estudo pretende estabelecer uma correlação entre a atividade biológica destas moléculas com sua estrutura molecular e suas propriedades eletrônicas. Cálculos teóricos usando técnicas baseadas em métodos semi-empíricos (AM1), e Teoria do Funcional da Densidade (DFT) - BLYP e B3LYP na base 6-31G - foram realizados no intuito de obter a geometria molecular e as propriedades eletrônicas dessa classe de fármacos. A análise das curvas eletrostáticas calculadas tornou possível a determinação da região de interesse para a aplicação da MIE. Nossos resultados indicam alguma relação entre os índices eletrônicos e atividade biológica para a classe de compostos estudados.

Texte intégral"Société du Canal de Provence" has been managing its hydraulic network thanks to the dynamic regulation for more than thirty years. The integration of a multivariable automatic controller, based on optimal control, will allow an overall optimization of the system. The development is made on the "Aix Nord" subsystem of the "Canal de Provence". A non-linear model is built, calibrated and validated with field measurements. The controller is proposed in two versions: an asymptotic one, and another one with a non-asymptotic component allowing to take into account predictions on future disturbances or objectives. A state observer and a perturbation observer are also defined. Robustness of both controller and observer is tested. A method for discrete control of pumping station is also defined. Classical tests on model allow studying of the behaviour of the controller. Finally, the new controller is compared to the current one in use on an example extracted from the backup files

Texte intégralThe problematic exploitation of border-line rivers, the use of underground water sources in the Lower Sahara and the pollution of cross-border waterways are issues currently of great importance in the Maghreb. The present study, which addresses the questions globally by using an integrated approach, aims to clarify and broaden our knowlegge of the matter in the hope of resolving these shared problems, encouraging a rational managment of such rare and unstable resources and establishing more active co-operation. Tackling the question of water appears indispensable if peace is to be maintained an consolidated in the region

Texte intégralThis work concerns the territories of four civitates located between Rhine and Meuse and their organisation during Roman times : the Leuci and the Mediomatrici in Mosellan Gaul, the Triboci and the Rauraci on the left bank of the Rhine. From the point of view of ancient writers, we have observed that this space has been appropriated since the Conquest, with the Rhine as a real or a symbolic frontier. We have established a hierarchy between the towns that structures these civic territories. The organisation of the civitates seems to correspond with a model based on a civitas capital in the centre of the territory, with other important towns all around the territory, like relays of the capital. If some of those towns, but not the majority, have a latenian origin, this model may be compatible with the will of the Roman authority. During late Antiquity, the organisation of the civitates have sometimes been deeply modified

Texte intégralDuring the past decades, major novel pathogenic roles of the steroid hormone,aldosterone, via the Mineralocorticoid Receptor (MR) have been identified in heart. Collectively,experimental studies and clinical trials, suggest a detrimental association between aldosteroneand life threatening arrhythmias that may be prevented by MR blockade. However, the signalingpathways and underlying mechanisms still remain elusive. We have accumulated evidence thatmodulation of Ca2+ signaling, especially Ca2+ influx via L-Type Ca2+ channel (LTCC), might bethe primary aldosterone/MR target in ventricular cardiomyocytes. Yet, the molecularmechanisms by which MR regulates expression of LTCC remain to be defined. Here, weinvestigated, in primary cultures of neonatal rat ventricular myocytes, the molecular eventscritical for aldosterone-Mediated cardiac effects on CaV1.2, the pore-Forming main subunit ofLTCC, which is encoded by the CaCNA1C gene.We showed that cardiac MR are functional as demonstrated by aldosterone-Induced MRnucleocytoplasmic trafficking observed by time-Lapse imaging of transfected GFP-Labeled MRusing confocal microscopy. Aldosterone exposure for 24 hours, induced a dose-Dependentincrease in CaV1.2 expression at both mRNA and protein levels. Analysis of the CaCNA1Cpromoter activity using luciferase reporter assays, revealed a dose- and time-Dependent activationby aldosterone. These effects were inhibited in the presence of either RU28318, a selective MRantagonist, or MR siRNA. In silico analyze enabled us to identify five putative GlucocorticoidResponse Elements (GRE) within the CaCNA1C promoter sequence. The mutation of the mostdistal GRE from Transcription Start Site (TSS) did not altered responses either elicited by theconstitutively active human MR (hMRΔ5,6) or dose-Dependent effects of aldosterone anddexamethasone (a synthetic glucocorticoïd with minimal MR effect). Mutations of the three nextones decreased responses to hMRΔ5,6 and aldosterone, whereas dexamethasone responses wereeither unchanged or increased. In sharp contrast, the mutation of the most proximal GRE fromTSS, increased responses to hMRΔ5,6, aldosterone and dexamethasone.These results provide new insights into the molecular mechanisms associated with cardiacMR activation, and suggest that LTCC is a primary MR target, with subsequent molecular andfunctional consequences that could lead to MR-Related cardiac dysfunction

Texte intégralThe precious Mediterranean red coral Corallium rubrum (L. 1758) is a long–lived colonial sessile octocorallian which develops a red calcareous skeleton well–appreciated since antiquity for its value in jewellery and ornamentation. Professional harvesting, poaching and mass mortality events associated with positive thermal anomalies are the major sources of disturbance for this species. These disturbances have caused a marked decrease both in the abundance and size of colonies in the present populations. The persistence of these populations is linked to management and conservation plans constructed using reliable information about both main life history traits and population dynamics. Despite its value meaning, little is known about the biology and ecology of red coral. The main goals of this study is to provide data about significant life history traits (growth and reproduction) of red coral populations dwelling along the Mediterranean French rocky coasts in order to contribute our understanding of the biology and ecology of this species. In addition, this study will provide information about the effects of mass mortality events on red coral populations in order to better understand how these disturbances affect its population dynamics. The mean growth rate of red coral colonies was 0. 15 mm per year in diameter. Despite the large number of populations studied, growth rates remained stable across a wide variety of habitats analysed. Habitat comparisons were made between cave entrance vs cave interior, 20 vs 40 m depth and Calanques region vs west coast of Corsica Island. However, fecundity (number of mature gonads per polyp) analysed on the same populations seems only to be influenced by food availability. Thus, red coral populations dwelling at the entrance of caves showed larger fecundity than populations dwelling at the interior of the same caves. On the other hand, populations dwelling in contrasted depths (18 – 22 m vs 39 – 42 m) did not show any significant differences on fecundity. The study of reproduction biology of red coral has been completed by studies on reproductive cycle, sex ratio (1:1 overall studied populations), age and size at first reproduction (less than 3 cm corresponding to 7 – 10 years), differential gonad maturity in contrasted locations in both cave and depth factors analyses, inter-annual variability on fecundity (it seems to be low along three years) and the effects of mass mortality events on red coral fecundity. Finally, experiments on thermal tolerance in aquaria have been performed using two populations dwelling at contrasted depths (11 – 14 vs 39 – 42 m). The upper thermal limit was 25 °C. At this temperature, red coral colonies showed necrosis after 10 – 15 days. Polyp activity and calcification was also affected by increase of seawater temperature. Three experiments indicate that colonies from shallow populations had greater thermal tolerance to elevated temperatures than those from the deeper ones. In conclusion, this study furnished data to complete information about population dynamics of red coral. It is the aim of this study is to contribute to the development of mathematical models that can be used to explore the response of red coral populations under different disturbance regimes, as well as to facilitate future research about genetic or environmental factors which can modulate responses of these populations to environmental changes associated to climate change. Finally, these informations will help to improve both management and conservation plans

Texte intégralPicoplankton includes planktonic microbes ranging from 0.2 to 3 μm in diameter. Among photosynthetic groups are cyanobacteria, and microbial eukaryotes whose ecology and diversity are poorly known. These picophytoplankton contribute significantly to oceanic carbon fixation and primary production. The objective of this thesis was to investigate the relative importance of autotrophic plankton along with heterotrophic picoeukaryotes. The study focused on samples of surface and subsurface chlorophyll maximum collected in the Gulf of Maine (July 2010) and the Scotian Shelf (April and October 2009). The combination of molecular techniques clone libraries and pyrosequencing, targeting 18S rRNA genes and transcripts as well as the functional gene psbA, which codes for a protein D1 of photosystem II were used. It was apparent that the picoeukaryotes are dynamic communities with distinct assemblages during the spring blooms compared to late summer - autumn conditions, and between regions near shore vs offshore. Differences in distribution, species composition and community structure were associated with hydrographic changes, where the temperature, which strongly influences the stratification, seemed to play a major role. Overall the study revealed the diversity of haptophytes and the high relative abundance of Mamiellophyceae (Chlorophyta). Heterotrophic flagellates varied over time for some taxa (Choanoflagellates, MAST-1, -4, -7) while others persisted. Comparisons between rRNA genes rRNA provided a new perspection on the status of communities and highlighted the potential of using both approachesto describe the state of the ecosystem.

Texte intégralThis work has the object to explain, with the thematic method, the importance of "the North" in the aesthetic and artistic theory of 19th century french poet Charles Baudelaire (1821-1867). There are two texts of 1846 which permit to know that Baudelaire is interested in the schematic relation between the romanticism and the North, since Madame de Stae͏̈l. But this role of schema the Middle / the North in his aesthetic and artistic theory was neglected until now in these Baudelaire's studies. This work aims to define the relations between the romanticism and the North, and that between the artist's temperament and the North, in analysing his articles about the art and the literature, and the poem "The Lighthouses". This point of view permits especially to explain the choice of artists and their order in the poem "The Lighthouses" and equally to know the Baudelaire's idea of history against the 19th century Progress

Resumo: Gastrópodes marinhos apresentam grande variação individual nas taxas de crescimento, que parece ser determinada em grande parte por fatores ambientais, bióticos e abióticos. Nesse sentido, o principal objetivo deste projeto foi comparar as taxas de crescimento do caramujo predador Stramonita haemastoma sob condições laboratoriais ótimas (sem predadores, competidores interespecíficos, ação de ondas, flutuações de maré e com suprimento alimentar ilimitado), e em condições naturais, onde um ou mais destes fatores ocorrem. Dois experimentos laboratoriais adicionais foram realizados para verificar os efeitos de 1) restrição alimentar periódica, e 2) densidade dos caramujos, nas taxas de crescimento de Stramonita. Ainda, o padrão de atividade deste gastrópode foi observado no campo. Indivíduos sob condições ótimas e naturais tiveram seus tamanhos medidos a cada quinze dias por seis meses. Os dois experimentos laboratoriais adicionais foram realizados por três meses, com os caramujos sendo medidos quinzenalmente. O padrão de atividade de Stramonita foi observado a intervalos de uma hora durante dois dias em um ciclo de maré de sizígia. As taxas de crescimento foram mais elevadas para os indivíduos sob condições ótimas do que para aqueles sob condições naturais, indicando que o crescimento sofre restrições no campo. Animais jovens apresentaram taxas de crescimento maiores que os adultos. Os indivíduos privados de alimento por períodos mais prolongados tiveram suas taxas de crescimento reduzidas, significando que circunstâncias desfavoráveis como tempestades, que impedem a atividade de forrageamento, podem afetar o crescimento de Stramonita. Caramujos sob condições de alta densidade cresceram menos e apresentaram maiores taxas de mortalidade que aqueles em baixas densidades. A maior atividade de Stramonita no campo foi observada durante períodos de imersão, provavelmente uma estratégia para minimizar os efeitos de dessecação
Abstract: Marine gastropods show great individual variation in growth rates, which seems to be determined mainly by environmental factors. The main goal of this project was to compare individual growth rates of the predatory snail Stramonita haemastoma under optimal laboratory conditions (without predators, interespecific competitors, wave action, tidal fIuctuations, and with unlimited food supply), and natural conditions, where one or more of these factors occur. Two additional laboratory experiments were made to examine the effects of 1) periodical starvation and 2) different snail densities on Stramonita growth rates. Individuais under optimal and natural conditions were measured every fifteen days for six months. The two additionallaboratory experiments were run for three months with snails being measured every fifteen days. Stramonita activity was observed hourly during two days in one spring in tidal cycle. Growth rates were higher under optimal conditions than under natural conditions, indicating growth limitation in the field. Young animais had higher growth rates than adults. Individuais that starved for longer periods had their growth rates reduced, suggesting that unfavourable circumstances, like storms which prevent foraging activity may affect Stramonita growth. Snails at higher density conditions grew less and had higher mortality rates than those at lower densities. Higher Stramonita activity in the field was observed during immersion periods, which is probably a strategy to minimize desiccation

Texte intégralIn the second half of the 19th century, the inner parisian suburb has been touched by a brutal development of industry. Under the weight of a strong demographic pressure, the inner north-east outskirt got violently urbanized, without physical planing or territorial organization. A large part of suburbanite industries produced classified goods coming under regulation established by the 15th october 1810 decree. This regulation has been enforcing for more than hundred fifty years. This regulation has been implemented in a specific way in the department of Seine. State and departmental authorities used it in order to discharge insalubrius activities and undesirable productions out of the capital. Prestigious parisian ambitions came true to the detriment of inner suburb. The north-east quarter received all kinds of productions needed by Paris and saw it landscape changing gradually. The inner suburb has been reacting to the situation little by little and denouncing it since 1880

Texte intégralLa Sous-province d’Opinaca, située dans le craton du Supérieur, est un important bassin néoarchéen de sédiments métamorphisés. Les modèles tectoniques disponibles pour la formation puis l’évolution de l’Opinaca sont variés, allant du prisme accrétionnel au bassin d’arrière-arc. L’étude tectonométamorphique proposée permet de définir le parcours prograde de la région et ainsi discriminer les modèles probables, chacun impliquant une progression du métamorphisme distincte. Dans le nord-ouest de la Sous-province d’Opinaca, des isogrades tracés à partir de minéraux indicateurs du métamorphisme soulignent une progression du faciès des schistes verts dans le nord-ouest au faciès supérieur des amphibolites au sud-est. L’étude de la chimie minérale des minéraux métamorphiques révèle une homogénéisation généralisée des zonations chimiques. Les relations texturales observées dans le secteur au nord de l’Opinaca et une modélisation de l’équilibre des phases indiquent un chemin P-T-t en sens horaire avec un segment en décompresson de 6 à 4 kbar, à ~ 600 °C. Dans la partie sud du secteur d’étude, le chemin PTt est caractérisé par une décompression isothermique suparsolidus de 9 à 5 kbar, à ~ 800 °C, L’âge de la sédimentation est définie par les populations de zircons détritiques et le recoupement d’intrusifs felsiques entre 2712 Ma et >2690 Ma selon les secteurs. La géochronologie U-Pb sur des monazites indiquent deux pics de métamorphisme, à ~ 2670 et ~ 2645 Ma. La datation des grenats avec le système Lu-Hf indique que la croissance du grenat correspond à la plus jeune génération de monazite, circa 2645 Ma. La première génération de monazite est interprétée comme liée à un événement métamorphique de basse pression n’impliquant pas la croissance de grenat. Ces résultats permettent de proposer pour l’évolution du bassin d’Opinaca un polymétamorphisme dans un environnement géodynamique d’inversion tectonique d’un basin. Après la sédimentation, un premier épisode métamorphisme de haute température affecte le bassin en extension vers 2670 Ma. Vers 2645 Ma, la fermeture du bassin et l’épaississement crustal provoque un deuxième épisode de métamorphisme, de type barrovien, caractérisé par une décompression isothermale possiblement aidée par un certain degré d’extrusion ductile
The Opinaca Subprovince, in the Superior craton, is an important Neoarchean metamorphosed sediments basin. Various models are proposed to explain the formation and evolution of the Opinaca, ranging from accretional prism to back-arc basin. The proposed tectonometamorphic study allows the determination of the prograde evolution of the basin and hence the selection of the most probable regional model, each being characterized by contrasting styles of metamorphic progression. In the north-western Opinaca Subprovince, isograds traced from index minerals highlight a progression from greenschist facies in the north-west to upper amphibolites facies in the south-east. The chemistry of metamorphic minerals shows a global homogenisation of growth zonation. In the northernmost Opinaca Subprovince, textural relations and phase equilibrium modelling indicate a clockwise PTt path with an isothermal decompression segment from 6 to 4 kbar at ~ 600 °C. In the southern part of the study region, the clockwise PTt path is characterized by stronger, suprasolidus isothermal decompression from 9 to 5 kbar at ~ 800 °C. We constrain deposition of the Opinaca greywacke from 2712 to 2690 Ma with the youngest detrital zircon population and crosscutting felsic intrusions. U-Pb monazite geochronology indicates two pulses of metamorphism, at ~2670 and ~ 2645 Ma. Lu-Hf dating of garnet supported by textural analysis and trace element mineral chemistry indicates that garnet growth is coeval with the younger population of monazite, circa 2645 Ma. The first generation of monazite around 2670 Ma is thus interpreted as a low-pressure metamorphic event that did not involve garnet growth. These results point towards a polymetamorphic evolution for the Opinaca Subprovince consistent with the tectonic inversion of a rift-like basin. Clastic sedimentation between 2712 to 2690 Ma in a magmatically active, rift-like basin was followed by regional low-P metamorphism at 2670 Ma. The onset of crustal shortening and thickening in the basin by 2645 Ma resulted in Barrovian-type metamorphism, and involved isothermal decompression that could have been accommodated by some degree of ductile extrusion.

Texte intégralOne new sociological reality have started in the Brazilian after the 1980's years. We observe that the originality theses mobilizations consist in the fact that these have been based in discourse ethnic. In short worlds, this populations claiming the access the land throughout an ethnic belonging to Black slaves, cimarrones, that have been present during the colonial period. Since this moment, we have verified a mobilization that culminates in the recognition institutional of communities traditional. Before, theses populations there were politically nonexistences, today they represent more of five millions of people. It is interesting to note that the strategy employed by these communities reproduces the preceding mobilization of the peasants of Northwest which declare themselves populations autochtones and in the 1980's years also are recognized by the State like traditional populations. Analyzing the significance of these transformations of categories, we made an ethnographic study about Mocambo the Porto da Folha localized in Brazilian Northwest. Our propose is analyze the significance of change theses categories. So we need explain as they construct their identity, as well as the incidences on the production of the ethnic language in Brazil
