Повний текст джерелаHigh Resolution (infra-metric) topographic data, including LiDAR photo-interpreted datasets, are becoming commonly available at large range of spatial extent, such as municipality or industrial site scale. These datasets are promising for High-Resolution (HR) Digital Elevation Model (DEM) generation, allowing inclusion of fine aboveground structures that influence overland flow hydrodynamic in urban environment. DEMs are one key input data in Hydroinformatics to perform free surface hydraulic modelling using standard 2D Shallow Water Equations (SWEs) based numerical codes. Nonetheless, several categories of technical and numerical challenges arise from this type of data use with standard 2D SWEs numerical codes. Objective of this thesis is to tackle possibilities, advantages and limits of High-Resolution (HR) topographic data use within standard categories of 2D hydraulic numerical modelling tools for flood hazard assessment purpose. Concepts of HR topographic data and 2D SWE based numerical modelling are recalled. HR modelling is performed for : (i) intense runoff and (ii) river flood event using LiDAR and photo-interpreted datasets. Tests to encompass HR surface elevation data in standard modelling tools ranges from industrial site scale to a megacity district scale (Nice, France). Several standard 2D SWEs based codes are tested (Mike 21, Mike 21 FM, TELEMAC-2D, FullSWOF_2D). Tools and methods for assessing uncertainties aspects with 2D SWE based models are developed to perform a spatial Global Sensitivity Analysis related to HR topographic data use. Results show the importance of modeller choices regarding ways to integrate the HR topographic information in models

Повний текст джерелаThis thesis aims at improving our knowledge of the near and distant sources controlling the exceedance of the regulatory thresholds of air quality, as detected by the air quality monitoring networks, at the strongly industrialized and urban site of Great Dunkirk Area (GDA). This appreciation is notably based on the calculation of a mixing state index of the particles, taking into account the heterogeneity of their elementary composition, this one being related to their residence time in the atmosphere and the distance between the sources and the studied receptor site. To do that, it was firstly necessary to develop a time resolved cascade impactor with high temporal resolution, named "TRAPS", which answered the need to follow the rapid changes observed within the atmospheric particles during pollution episodes. Coupled with a particle size analyser and after individual analysis of the collected particles by electron microscopy (SEM-EDX), TRAPS allows to report the physicochemical evolution of atmospheric particles over time. In the first part of this thesis, laboratory experiments and a field campaign allowed to validate our prototype, to report the dynamics of particle deposition on the impaction stages and to verify the cut-off diameters of the coarse and fine stages of TRAPS, determined respectively at 1.32µm and 0.13µm. A statistical study of PM₁₀ pollution episodes occuring over the GDA was then carried out over 3 years, between 2018 and 2020. It allowed us to identify 12 main types of episodes based on their spatial extent, but also on the local conditions of pollutant dispersion. We were able to identify local episodes and regional episodes observed, either in stationary or dispersive atmospheric conditions. While 78% of the PM₁₀ exceedance days correspond to local episodes, the remaining 22% correspond to pollution plumes with at least a regional extent, with an equal proportion of exceedance days in dispersion and stationary conditions. Except for very localized episodes, a detailed study of these pollutions episodes shows the systematic presence of a period of pollutant accumulation, of about 10 hours, characterized by an important contribution of fine particles (PM₂.₅) except for episodes of limited spatial coverage. The last part of this work consisted in the study of the composition and mixing state of the individual particles collected during pollution events in the GDA in 2021. The campaign allowed the sampling and characterization of 5 pollution episodes, during which TRAPS was deployed in parallel with other instruments providing complementary information on aerosol granulometry, or atmospheric dynamics. Nearly 28000 individual particles were characterized by SEM-EDX. With more than 90% of the samples associated with values of the mixing state index higher than 0.5, it can be said that the particles collected in the GDA during pollution episodes are in general of very heterogeneous composition at the particle scale (internal mixing). Nevertheless, the results show an influence of the local or transported origin of the particles on their chemical composition, but also on the mixing state index. An increasing evolution of this index with the particles residence time during these events is observed

Повний текст джерелаPhthalates and alkylphenols are organic molecules generated by the chemical industry, entering the composition of plastics, for phthalates, and detergents for alkylphenols. Their worldwide productions are around 6 million tons and 500,000 tons, respectively. It is now obvious from the concentrations and contents measured in the various environmental compartments that phthalates and alkylphenols are ubiquitous environmental contaminants. Indeed, they are found in all environmental compartments (from the atmosphere to the natural environment) at significant levels. These contaminants are also recognized as endocrine disrupting compounds and can cause damages to fauna and flora present in the natural environment. This work has identified levels of wastewater contamination of phthalates and alkylphenols in various environmental compartments in urban areas. Thus, samples taken, during dry weather periods, were used to determine the quality of raw water for global parameters, phthalates and alkylphenols within industrial and domestical discharges as well as the sewer network and a major Parisian sewage treatment plant (Seine Centre, Colombes, 92). These results reflect certain characteristics and disparities of the sewer network, including both high variability of the sampling and the contamination levels by these micropollutants. For industrial discharges, significant disparities have been observed between the different sectors listed (textile manufacturing, surface treatment, metallurgy, pharmaceutical industries, etc.). Overall, the results confirm that household inputs correspond to the first source of contamination in Parisian conurbation. Indeed, the contribution of industrial inputs is less than 5%, for all compounds, whatever the industrial sector. The study of the Parisian sewer network showed some temporal stability of wastewaters in the downstream part. This work however also highlighted disparities and similarities between the sub-watersheds drained by the sewer network. Thus, the northern part of the Parisian network (SDA and CAA) appears to be more contaminated than the Southern part (CAB and SAR).The results obtained for Seine Centre wastewater treatment plant (WWTP) confirms the effectiveness of the treatment processes on the removal on the routine water quality parameters. Additionally, the results on the elimination of phthalates and alkylphenols in sewage treatment plant (yields above 83% for all compounds) confirm that even if WWTP are initially not designed for reducing and/or eliminating micropollutants, they proceed significantly. During primary treatment, physicochemical lamellar clarification underlined the removal of hydrophobic pollutants such as DEHP, NP, DnBP and BBP. During the secondary treatment, biofiltration highlighted its effectiveness in eliminating all pollutants, as well as volatile compounds (DEP) and other contaminants

Повний текст джерелаPort Gentil is an industrial and harbour town relatively young. After having been the principal way of penetration of the interior of the country during the fifteenth century, Mandji remained a long time the stronghold of wood before becoming the economic capital of Gabon thanks to and especially oil which covers more 70% of the receipt of Gabon. This industrialization involved flows of populations to meet the industrial requirements in labour. Thus, Port-Gentil ast since the years 1950, the second most populated city country, in spire of the natural conditions unfavorable to the installation of the men. The city thus developed of its site initial towards the marshy west and whose altitude of the grounds is very in lower part of the sea level. Blow, the populations are victims of the floods. In addition, the installation of industries along bay of the Cape-Lopez and especially the infrastructures oil (pipelines and gas pipelines) became spaces at the risks. Because, the current urban development largely crossed these limits. Beyond the fact that Port-Gentil always does not receive on behalf of the State the rebate which it deserves, the city is today confronted with the problems of floods, anarchistic urbanization, an insufficiency maintenance of the network cleansing, of pollution industrial, and especially of a coastal erosion. All these risks are responsible for morphodynamic urban, harm pubic health and obstruct extension continues urban fabric. The stablishment of the men and the management of environment of Port-Gentil thus imply the control of these instabilities. That implies an application of the plan; installation and cleansing, the protection of the emissary of urban drainage and, the rigorous management of waste

Повний текст джерелаFine airborne particulate matter (PM₂.₅) can be inhaled and retained in deep lung for long periods, leading to onset or exacerbation of cardio-respiratory diseases. However, the complex composition of PM₂.₅ makes difficult the study of their mechanisms of action. This work fits into a global approach aiming to identify the toxicity mechanisms involved in a putative PM₂.₅ carcinogenicity, in association with PM composition. We study six PM samples collected either under industrial, urban or rural area, in spring-summer 2008 or autumn-winter 2008-2009 seasons. Biological fraction analysis revealed numerous and diverse bacterial and fungal components. We carried out Ames tests revealing a high mutagenic potency for PM samples, presumably linked to their nitro-aromatic content. Based on previous cytotoxicity assays, we studied PM effect on bronchial epithelial cell line BEAS-2B, at two concentrations (3.75 and 15µg/cm²). We demonstrated gene induction of several xenobiotic metabolizing enzymes involved in polycyclic aromatic hydrocarbons metabolic activation. This was associated with an increase in their catalytic activity, leading to bulky DNA-adducts formation in exposed cells. Furthermore, PM₂.₅ lead to DNA single- and double-strand breaks, micronuclei formation, and disturbed telomerase activity. In addition to these genotoxic effects, our study revealed epigenetic alterations such as P16ᴵᴺᴷ⁴ᴬ promoter hypermehylation, histone 3 post-translational modifications, and miRNAs expression changes. Considering the impact of chemical composition on PM toxicity, organic compounds lead to the highest genotoxicity, whereas metals seem to induce more pronounced epigenetic modifications. Altogether, our results indicate that the studied PM₂.₅ samples, through cooperative action of organic and inorganic fractions, may lead in vitro to multiple alterations involved in initiation and promotion steps toward pulmonary carcinogenesis

Повний текст джерелаThe main goal of this PhD was to evaluate the impact of the anthropogenic activities (urban, industrial or agricultural activities) on aquatic systems. The Fez metropolitan area and its impacts on the Sebou River, the main Moroccan river, were chosen as a case study. The Fez agglomeration (~1M hab), is surrounded by the Fez River, receiving the wastewaters of this developing city and then flowing into the Sebou. This work was performed on two sites along the Sebou River (upstream and downstream from the confluence with Fez River), and one site in the Fez River, downstream from the Fez city. One sampling campaigns of sediment cores and eleven sampling campaigns were performed during low flow conditions to quantify nutrients, organic carbon and trace metals and to study the dynamic and the transport of trace elements in the Sebou and Fez rivers. The obtained results revealed a global increase of studied elements in the Sebou River from upstream to downstream sampling site, in both sediments and water column. A moderate level of contamination by butyltins was observed, with monobutyltin being the dominant species across all sites and depths. The lowest level of metal pollution was identified in the Sebou's sediments upstream Fez city. Whilst the Fez' sediments were heavily polluted and exhibited bottom-up accumulation trends, which clearly evidence recent inputs from the untreated wastewaters of Fez city. The increase of metal levels in Sebou downstream sediments reflects a significant contribution of polluted particles from the Fez River. Dissolved and particulate concentrations of most of the analyzed elements in the Sebou, upstream from Fez city, are close to the natural rivers, except Cl-, Cr, Na+ et NO3- probably due to untreated urban inputs from several small/medium-size towns located upstream Fez. In the opposite On the contrary, high dissolved and particulate trace metals concentrations in the Fez River clearly indicated strong anthropogenic inputs from Fez city. Most of the studied trace metals originated from anthropogenic sources, underwent significant changes of Kd and behaved non-conservatively in the Sebou/Fez waters mixing due to drastic changes of the waters quality (anoxic condition, high concentration, high organic matter content). Dissolved/particulate partitioning were correctly assessed by WHAM-VII modeling for Cu, Pb and Zn, depicting significant differences in chemical speciation in Fez River when compared to Sebou one

Повний текст джерелаThe past forty years have been deeply impacted by the triumph of the neoliberal doctrine on a global scale, as much on the political as on the economic level. Overall, the mechanisms of market deregulation and the reorganization of social compromises induced by this doctrine are well known. But urban geography is still struggling to identify and qualify their importance for the city's local production, particularly in France where the planning tradition and public institutions remain strong. Concomitant with the emergence of urban planning by project and with the dissemination, on a great diversity of local contexts, of generic urban models such as the “sustainable city” or the “creative city”, etc., neoliberalization raises the question of a radical transformation of the production system of the city as a whole. This transformation does not only affect planning policies, but it concerns more generally a significant portion of the standards and values which preside over the design, the representations and the appropriations of the contemporary city. In other words, it has an effect on principles which serve as a guide for evaluating and legitimizing urban policies and the class compromises that allow them. By analyzing and articulating these local transformations in four former industrial districts of medium-sized French and German cities which have undergone an intense process of urban renewal for almost thirty years, this work questions the processes of urban revaluation in areas that were nevertheless strongly devalued at the beginning of the 1990s. This review, which covers a long period of time (1990-2020), aims to show that this revaluation takes the form of a process of recapitalization of the urban space which articulates symbolic values and Market value, according to a precise cycle of subordination of the first to the second, which appears typical of the neoliberal destruction / creative process; and in which a new class compromise is cemented between the real estate bourgeoisie and fractions of the middle classes, strongly endowed with cultural capital

Повний текст джерелаDriving a truck is a complex professional activity that takes place in a dynamic and constant changing environment. It needs a specific learning and it is set in a strict regulated framework including French labour code (Code du travail) as road regulation. Strong spatio-temporal pressure should be added to those characteristics. These constraints entail to drivers the use of operative strategies to achieve the main objective of their activity: respect of delivery time in optimal conditions of safety, security and productivity.This thesis deals with the contribution of cognitive psychology to the design of driving assistance systems for trucks. Works are intended to integrate, from the design of new systems, the demands of human cognitive functioning in real situation and the needs and expectations of drivers so that adapted and usable technological solutions could be proposed to them.Applied part shows two major dimensions of truck driving activity: productivity through the issue of the eco-driving assistance (“Conduite Economique Assistée, ADEME- RENAULT TRUCKS” project) and safety through the issue of the assistance to detection and protection of vulnerable road users (“VIVRE2, ANR-PREDIT05-LUTB” project).From a scientific point of view, the thesis ends with a proposal of a model of human functioning in finalized activities, of which is added an adapted model of the truck driving activity. The analysis performed in real environment enhance knowledge, on the one hand, on the applied driving strategies to the eco-driving of a truck in extra-urban environment and, on the other hand, on the components of the activity of drivers doing deliveries in urban environment. Moreover, works performed in VIVRE2 project allowed to specify representations and risky behaviours of vulnerable users with relation to trucks in town.From an applicative and ergonomic point of view, works on driving dynamic simulator allowed the evaluation of an innovative man-machine interface which could be adapted to eco-driving and the proposal as well as the evaluation of assistance systems to guarantee safety of vulnerable users during low speed manoeuvres in urban environment
