Morel, Sophie. „Complexes d'intersection des compactifications de Baily-Borel : le cas des groupes unitaires sur Q“. Paris 11, 2005. http://www.theses.fr/2005PA112250.
Der volle Inhalt der QuelleIn this work, we calculate the trace of a power of the Frobenius endomorphism on the fibers of the intersection complex of the Baily-Borel compactification of a Shimura variety associated to a unitary group over Q. Our main tool is Pink's theorem about the restriction to the strata of the Baily-Borel compactification of a local system on the Shimura variety. To use this theorem, we give a new construction of the intermediate extension of a pure perverse sheaf as a weight truncated of the full direct image. More generally, we are able to define analogs in positive characteristic of the weighted cohomology complexes introduced by Goresky, Harder and MacPherson

Der volle Inhalt der QuelleThe first part of this thesis dealing with the study of the contract of leasing concerning bankruptcy or winding-up emphasizes the weakness of leasers co-contracting creditors. The demonstration can be proved by the established fact that the control of his contract is missing. He cannot choose to break the relationships granted by contact, pleading his partner's bandruptcy or winding-up. He cannot either stand in opposition to the transfer of his contract to the buyers of his indebted firm. The risks of non-payment debits previous to the opening judgment of the buyer's bandruptcy or winding-up are great. Even if the solution deserves some touches, the established payment garanties to the benefit of creditors, subsequent to the opening judgment, will be, in most cases, a lark-mirror. The rule of unreliability characterizes the payment of the creditor leaser. The second part of this thesis put forward the powes of the leases co-contracting ownes. His overwhelming power is, however, submitted to the condition of opposability of his patent rights. Since the law of the 10th of june 94 this has been reduced as a regular publication of its contract to the record-office having juridiction, which, howeres, remains the weak spot of the leaser. Once his opposability right on ownerships has been laid down the leaser can carry it out with a certain adaptability. Moreover, the legislator protects the leaser from the daywhen his ownership right was transferred

La Rochelle, 2009. http://www.theses.fr/2009LAROS266.
Der volle Inhalt der QuelleThe littoral zone contains ecosystems featuring high and diversified primary production which constitute the base for complex food webs. Among the producers, seagrass beds produce matter which in general is poorly consumed, thus contributing to the detritus food web. Furthermore, seagrasses form a support for high epiphyte production. This work was carried out to verify these general patterns for the functioning of an intertidal Zostera noltii seagrass bed. Biomasses of different producer and of consumer compartments were estimated and their spatial and temporal variations assessed. The fate of the produced matter was studied by a multi-tracer method using natural isotope tracing and fatty acid profiling. It is shown that epiphyte biomass was low, thus comprising a negligible resource for consumers. Among the macrofaunal consumers, grazers dominated (73% of macrofaunal biomass). Conversely, the meiofauna represented 30% of the total biomass of benthic consumers. When epiphytes were lacking, microphytobenthos was the principal food resource for most of the macrobenthic species (deposit feeders, grazers). The seagrass itself is not much used by the invertebrate consumers and its fate in the food web remains poorly understood. In conclusion, the results demonstrate the minor role of epiphytes in the trophic web of this intertidal seagrass bed. The benthic invertebrates exploit another algal resource: the microphyobenthos

Der volle Inhalt der QuelleThis PhD dissertation, devoted to evaluate the impact of an invasive species on ecosystem functioning, presents two originalities: first, the choice of an indigenous species as biological model. This a priori paradoxical option allows us to further investigate the concept of biological invasion, and propose to include native and exotic species within the definition of invasive species. Second, a systemic approach. Based on an interdisciplinary approach, this research took into account simultaneously the three components of effects caused by invasive species described in the conceptual framework of Crooks (2002). This study, which deals with the invasion of salt marshes of the Mont-Saint-Michel Bay by the sea couch grass Elymus athericus Link, demonstrates that a single invasive species can significantly alter three fundamental functions of an ecosystem

Der volle Inhalt der QuelleThe purpose of this PhD thesis was to evaluate the potential of coastal sediment in recording environmental changes. With this aim in view, three coastal environments have been chosen along the French Atlantic coast: the Arçay sandspit for past wave climate record; the Marennes-Oléron Bay and Arcachon Lagoon to decipher among the multiple forcing parameters controlling estuaries sediment-fill. The Arçay Spit is a compound spit displaying an elongation mean rate of 26 m. Yr-1. Morphological and wave modeling approaches since 1979, show that energetic swells seem to cause massive sand accumulation and spit elongation, whereas less energetic swells appear to be responsible for small sand accumulation and spit curvature. Such mechanism seems to be responsible of the successive hook ridges accretion observed along the Arçay Spit since the second half of the 20th century. The Marennes-Oléron Bay and Arcachon Lagoon have been successively analyzed and compared following a combination of VHR seismic, sediment cores and historical and present-day bathymetries. The sediment-fill of the Marennes-Oléron Bay is rapid since the 19° century and complex since 8000 yrs BP, due to multiple forcing parameters. The sediment-fill of the Arachon Lagoon displays a balanced budget since the 19th century and seems to be mainly controlled by the partial closure of this lagoon since 2500 yrs BP. Numerous differences observed in those two estuarine environments give insight on relative influence of local forcing parameters including bedrock morphology, tide, waves, sediment supply and human impact

Der volle Inhalt der QuelleÀ l’heure actuelle, la MRC de Kamouraska se demande si elle devrait renaturaliser plusieurs des marais salés endigués depuis le siècle dernier. Les digues, ou aboiteaux, ont été mises en place principalement pour permettre aux agriculteurs d’agrandir la superficie de leurs terres et ainsi augmenter leurs revenus. À l’heure où l’on parle de protection de l’environnement, de changements climatiques, de développement durable et où les discours de certains scientifiques portent sur l’érosion et le coincement des marais, on se demande si le renversement de l’ancienne politique d’endiguement et l’adoption d’une politique de renaturalisation des berges ne seraient pas des avenues à envisager. Mais à quel état faudrait-il renaturaliser les marais? À quel moment dans le passé exactement? La période pré-contact? Préindustrielle? Pour répondre à cette question, il faut effectuer un retour dans le temps, avant les premières modifications anthropiques importantes du milieu. Ce retour se fera à l’aide de cartes anciennes, de textes, de photographies aériennes et d’ArcGIS afin de mieux saisir l’évolution biophysiques du marais avant, pendant et après son endiguement. Le marais choisi pour cette recherche est celui de la baie de Kamouraska, situé près du village de Saint-Denis-de-Kamouraska, dans la MRC de Kamouraska. Les résultats de la recherche démontrent que l’impact de l’aboiteau est important : il a amputé plus de 70 % de la surface du marais et réduit de manière importante certaines zones de végétation, affectant ainsi l’habitat de la faune et de la flore. Les conclusions tirées de l’étude sont qu’il faut, dans une optique de développement durable, reconsidérer l’utilité de l’aboiteau et l’usage du marais.

Baux, Noemie. „Dynamique d'habitats benthiques sous contraintes anthropiques : le cas du site de dépôt de dragage d'Octeville“. Thesis, Normandie, 2018. http://www.theses.fr/2018NORMC243/document.
Der volle Inhalt der QuelleThe aim of this thesis is to assess the impact of dumping by Le Havre harbour on the faunistic and sedimentary environment near the Octeville dumping site (Eastern part of the bay of Seine). This thesis propose an original scientific approach, including an integrated view (1) by the use of geochemical markers coupled with a sedimentary study (2) a study of the spatial and temporal benthic macrofauna dynamics with an experimentation in situ (3) the creation of a new multicriteria specific indicator of the dumping pressure and (4) a study of the food web with the development of an ECOPATH model. On the one hand, the results showed the existence of a sedimentary equilibrium area in the north-west, with two opposite TOC gradients, controlled by tidal and swell. Harbour sediments can be identified by their different chemical compositions. The area impacted by the dumping is limited. On the other hand, the benthic macrofauna appears less impacted by the dumping. The community is adapted in the bio-hydro-sedimentary environment of the study area. Variations in abundance and dominance have been observed since 2003.In addition, a new indicator allows the classification of dumping impact. The food web is currently stable in both impacted and not impacted areas

Der volle Inhalt der QuelleThe Marennes-Oléron Bay, Europe’s major oyster production zone, receives direct particle and water inputs by the Charente and the Seudre Rivers. The bay is also indirectly influenced by inputs from the Gironde Estuary, depending on hydrological and meteorological forcing. Fluvial trace metal inputs via the Charente and Seudre Rivers were evaluated during 2006-2007. Trace metal fluxes in the Seudre River were negligible due to its low mean annual freshwater discharge. Dissolved (<0.2µm) and particulate Cd and Cu concentrations and specific fluxes in the Charente River were similar or higher than those in the Garonne River. The reactivity of trace metals in the Gironde/Charente Estuaries, in the coastal zone and in the Marennes-Oléron Bay was investigated by 20 oceanographic campaigns and by a monthly monitoring (2007) of the Southern Marennes-Oléron Bay. The major parts (>90%) of total dissolved Cd, V and U concentrations along the turbidity and the salinity gradients were present in the labile fraction. In contrast, 30-70% of dissolved Co concentrations and 50-60% of dissolved Cu were strongly-bound to dissolved complexes. Based on 15 dissolved trace metal profiles, we evaluated the variability of dissolved trace metal distributions and speciation in the Gironde Estuary and proposed an empirical model for the estimation of dissolved trace metal annual net fluxes exported to the coastal ocean. Coupling ADCP measurements with geochemical data obtained at the Gironde Estuary mouth during entire tidal cycles and for contrasting conditions, we determined the residual particulate trace metal daily net fluxes. Comparison of our results with a hydro-sedimentary model allowed estimating the particulate trace metal net fluxes of the Gironde Estuary at the annual scale for 2007. Characteristic trace metal ratios in the residual particulate fraction of SPM and sediment were identified to trace particle transfer from the Gironde to the Marennes-Oléron Bay. This approach and the study of the shape of the turbid plume by satellite imaging suggest that the Gironde Estuary contributes 50-75% of the total annual SPM inputs into the bay via the Maumusson inlet. Based on these original results and combining in situ measurements and desorption experiments we proposed an annual budget of Cd and Cu fluxes into the Marennes-Oléron Bay. Dissolved Cd fluxes of the Charente Estuary accounted for ~61% of the total Cd inputs into the Marennes Oléron Bay, while ~60% of the total Cu inputs were transported by the particles from the Gironde Estuary

Der volle Inhalt der QuelleThe sale of a business is one of the most important insolvency solutions.However it’s a hard task to determinate creditor’s rights under these circumstances.Insolvency law has deeply changed consequently to main reforms (Act of July 26, 2005 called the “Safeguard Act”, Order of December 18, 2008 and to a lesser extent Order of March 12, 2014).At the same time, guarantee law has been modified by lots of reforms too (Order of March 23, 2006, Act of February 19, 2007, Act of August 4, 2008, Order of January 30, 2009).These reforms were fragmented. Furthermore they have been built without guideline. As a result, the articulation between insolvency law and guarantee law is very difficult.The theoretical and practical questions generate a real legal insecurity.The goal of this research work is to make insolvency practitioners propositions based on, amongst others, doctrine’s comments and criticism. The objective of these propositions is to establish a better balance between the pluralities of interests involved

Der volle Inhalt der QuelleCarrageenan (Car) is a polysaccharide extracted from red algae and is widely used as thickener, stabilizer and gelling agent in various products. Properties of Car extracted from different algae species cultured at Cam Ranh Bay in Vietnam were characterized. Kappa car extracted from K. alvarezii and iota Car from E.denticulatum were selected to study the rheological properties and the microstructure of individual and mixed car solutions in presence of CaCl2 and KCl. Mixtures showed a two-step gelation process with gelation temperatures that coincided with those of corresponding individual kappa and iota Car solutions. However, the stiffness of the mixed gels was much higher than the sum of the corresponding individual gels. Confocal laser scanning microscopy and turbidity measurements showed that the kappa Car gel was always more heterogeneous than the iota Car gel, but less in the mixture than in the individual system. The results show that microphase separation of iota and kappa Car in mixed gels is highly unlikely.The mobility of Car chains in individual gels of kappa and iota Car and their mixtures was determined using fluorescence recovery after photobleaching. Slow recovery was observed for the gels showing that a fraction of the Car chains remained mobile. The fraction of mobile chains in the gels varied between 25% and 75% depending on the type of Car and the type and concentration of salt. The fraction of mobile chains in gels was not correlated to the gel stiffness. These results were confirmed by the release of Car from gel fragments into excess solvent. It was found that released Car chains were smaller than the average size of the initial Car sample

Der volle Inhalt der QuelleThis study considers the period between the collapse of the Palace of Knossos (end of 14th c. B.C.) and the birth of the Greek city-state (mid 7th c. B.C.) in the region of the Mirabello Bay, in eastern Crete. It aims to define the formation process of the polis in this part of the island. Evaluating results of archaeological surveys and excavations conducted in the region, the study analyzes and interprets patterns of occupation and settlement structure from archaeological and geographical perspectives. Significant changes in material patterns and transformations of material culture are characterized for each chronological phase, following thematic threads of religious, funerary, residential, and political contexts. The results are combined in a new synthesis which emphasizes the main traditions and innovations from which the polis arose in the Mirabello region. The research is presented in three volumes : Volume I gives the detailed results of an archaeological and geographical exploration of the region ; these data are further analysed in Volume II ; maps produced for the study are gathered in Volume III

Der volle Inhalt der QuelleComprehensive contracts in public procurement constitute a class of contracts that have been formed gradually since their creation and play a major role, for instance in the action of public entities and local authorities. Partnership agreements became the main element of this family of legal instruments. They superimposed to compose a group that is hardly comprehensible by territorial authorities, which minimise their utilisation and success. Analyses of the case of Lourdes, of projects led by local authorities as well as the use of comprehensive agreements by the government are all examples that highlight the necessity of carrying out a real overview of the situation. After a decade of practicing and observing the use of public-private partnerships, it appears that the necessity of translating the achieved assessment into a real clarification of the different types of public procurements is more important than ever. The adoption of public procurement directives and concession directives in 2004 and the order relating to public procurement setting up in 2015 bring out the pertinence of the subject as well as the importance of proceeding to a major reorganisation of the French public procurement law

Der volle Inhalt der QuelleSince 1979 the bay of Mont-Saint-Michel in France has been listed by UNESCO as a world heritage site for its cultural and natural elements. This “nature-culture” duality is easily observed at the site as well as in the thousands of images representing the Mont-Saint-Michel (MSM). On one side there is the mount, a granitic rock surrounded by water at high tide and surmounted by an abbey. On the other, there are vast expanses of tidal marshes and flats. The beauty of this landscape has made it a world-renowned touristic destination, endowing it with an important role in the regional economy with an estimated three million annual visitors. However, this popular landscape is in danger of transformation as a result of the progressive encroachment of the salt marshes separating MSM from the continent. The insularity of MSM is thus under threat of disappearing in the next forty years without human intervention. Because such a loss of insularity would be catastrophic for the tourist economy of the region, French authorities launched the project Restore the Maritime Character of Mont-Saint-Michel (Rétablissement du Caractère Maritime du Mont-Saint-Michel, or RCM) to “restore the natural ecosystem” of the bay by limiting siltation around MSM. In an attempt to better understand the ecological repercussions of the RCM project, this study relies on social and natural science methods. Using archaeological and historical information, as well as data gleaned from sedimentological studies, aerial photographs, LiDAR and tide gauges, it is possible to present an integrated vision, both natural and cultural, of the evolution of this heritage bay. The results suggest that the work carried out within the framework of the RCM project have drastically altered the ecological trajectory of the southern half of the bay, creating a suspended state of natural development that this study interprets as an anthropogenic climax.
Parlier, Emmanuel. „Approche quantitative de la fonction de nourricerie des systèmes estuaires-vasières : cas du bar européen (Dicentrarchus labrax, L. 1758 ; a.k.a. Morone labrax) dans cinq nourriceries du Ponant : estuaire de la Seine, estuaire de la Loire, baie du Mont Saint-Michel, baie de Saint-Brieuc et baie de l'Aiguillon“. La Rochelle, 2006. http://www.theses.fr/2006LAROS169.
Der volle Inhalt der QuelleCoastal fish populations settle more or less frequently, at different stages, estuarine systems. Tidal marshes are one of the components of these mosaics of habitats. The first part of this work describes fish assemblages through the utilisation of these systems by fishes analysed in order to propose revised functional classification of ecological guilds. This new classification is used to compare four fish communities of estuarine system of the western coast of France : the Mont Saint-Michel Bay, the Saint-Brieuc Bay, the Loire estuary and the Aiguillon Bay. The second part aims at characterizing the nursery function as defined by Beck et al. (2001). A combinative approach based on gut content analysis, and stable isotope analysis shows that YoY sea bass (Dicentrarchus labrax) that are caught in tidal marshes feed actively in situ and that the salt marsh's preys contribute significantly to the first year's food resources. An examination of the microstructure of the YoY sea bass otoliths using SEM shows characteristic marks, which are interpreted as fingerprints of the passage in the salt marsh. The microstructural analysis showed that sea bass recruit in estuarine areas after variable length of time (33 days to 126 days) spent in marine waters during migration from spawning areas to estuaries. After entry into estuarine complexes, growth rate increases. Microchemical analysis of the whole otolith using ICPMS technology revealed characteristic signatures of each of the studied estuarine systems. This suggests that the chemical composition of trace elements in the otolith can be used as chemical tag of the fish. After a synthesis of this combinative approach, a reflection is committed concerning the effectively of these approach in order to advise managers. The same though is engaged to evaluate the sustainability of these studies that mix strong field investments and theoretical ecology (guilds, life history traits. . . )

Electronic Thesis or Diss., Avignon, 2024. http://www.theses.fr/2024AVIG0621.
Der volle Inhalt der QuelleThe health benefits of fruit and vegetables are partly due to their richness in phytochemicals such as carotenoids. The aim of this thesis was to combine several disciplines to analyze the relationship between growing conditions, carotenoid sequestration and the health value of fruit. The health value of fruit is assessed at various levels: I) the micronutrient composition of mature fruit; II) the bioaccessibility of carotenoids in an in vitro digestion model; III) the metabolic phenotype of C57BL/6JRj mice supplemented with fruit powder for 12 weeks in a model of induced obesity; IV) the vascular function of hyperglycemic Wistar rats fed with high antioxidant capacity fruits. Two types of fruit described as carotenoid rich matrix, namely six tomato genotypes (Solanum lycopersicum, 'industrial tomato' type genotypes: H1311, M82, IL2-5, IL54, IL6-2 and IL12-4) and a lycium genotype more commonly known as 'goji' (Lycium barbarum, cultivar FPW07), were grown in a controlled environment with two water regimes. A 'Control Irrigation' (CI) regime with complete restoration of evapotranspiration, and a stressed 'Deficit Irrigation' (DI) regime, in which irrigation volumes were halved from anthesis to harvest compared with the CI treatment. We hypothesized that water deficit and/or post-harvest treatments (steaming, drying, etc.) may modulate the health value of the fruits by affecting their micronutrient composition and the bioaccessibility of carotenoids. The results of this work showed that in an in vitro digestion model, DI globally decreases carotenoid bioaccessibility. In vivo, the results suggested that tomato or goji berry consumption may be associated with positive health effects in a metabolic and vascular context, with effects largely dependent on genotype and post-harvest treatment studied, but not necessarily water treatment. Thus, this work suggests that genotype and/or post-harvest treatment are major levers to improving the health value of fruit throughout the production chain
Racine, Calypso. „Écologie des foraminifères benthiques en domaine arctique dans un contexte de changements climatiques : cas des mers de Chukchi, Barents et Baffin“. Thesis, Bordeaux, 2019. http://www.theses.fr/2019BORD0008/document.
Der volle Inhalt der QuelleBenthic foraminifera are widely used in oceanography as paleoclimate and paleoenvironmental bio-indicators due to their presence in all marine environments, their sensitivity to environmental changes and their great capacity to fossilize. However, the use of benthic foraminifera as paleoenvironmental proxies requires a good knowledge of the ecological conditions and the parameters controlling species distribution. Although knowledges about the ecology of benthic foraminifera are improving, they remain sporadic in Arctic area, a complex ecosystem characterized by multiple interactions between the atmosphere, the ocean and the cryosphere and particularly sensitive to change and vulnerable to global warming. Temperatures in the Arctic have risen twice as fast as the global average over the past decades, a phenomenon that has been dubbed the “polar amplification of global warming”. In this context, this thesis aims at better understanding the ecology of living benthic foraminifera in Arctic regions and at defining the importance of environmental controls on fauna such as water mass properties, primary productivity, organic matter flux as well as sea-ice dynamics. Living benthic foraminifera were identified in the first centimetres of 21 surface sediment cores collected in three Arctic areas during summer in 2014 and 2015: Baffin Bay and the Barents and Chukchi Seas. These three regions present specific characteristics in terms of sea-ice cover, water mass circulation or primary productivity. Our results suggest that these factors influence the distribution of benthic foraminifera. The flux of organic matter resulting from primary productivity intensified during spring and summer periods near hydrographic polar fronts, sea-ice edges (marginal ice zones) and in the north water polynya (Baffin Bay) increases the fauna’s densities and diversity and favours the development of specific species. Nonionellina labradorica in cold Arctic waters and Cassidulina neoteretis associated with Atlantic waters respond to fresh supply of organic matter while Melonis barleeanus is found in environment rich in degraded organic matter. In deeper oligotrophic environments, Oridorsalis tenerus is a ubiquitous species associated with Cibicidoides wuellerstorfi on the west continental margin of Barents Sea and Ioanella tumidula in the deeper basin in the north of the Chukchi Sea. Physical and chemical water mass properties also affect the distribution of living benthic foraminifera. In the Baffin Bay and the continental shelf of the Chukchi Sea, corrosive waters lead to carbonate dissolution, favouring the dominance of agglutinated species. This thesis hence contributes to calibrate the benthic foraminifera to their environment and to improve their application as paleoclimate and paleoenvironmental proxies in the Arctic. Finally, a preliminary study about fossil benthic foraminifera in three cores of Barents Sea allowed to show variations of environmental conditions during the last two centuries
