Full textThis study offers the first full-length translation of eight texts written by Ben Jonson for Jacobean court masques. The masque, a cross-disciplinary genre and the counterpart of the French ballet de cour and Italian intermezzo, was short-lived (1605-1640), but dazzling. The first volume traces its origins and the work of the two artists who improved it over its predecessors : Jonson, by the quality of his texts, and Inigo Jones, whose lavish stage designs reduced the text to a mere foil in the next reign. Then, a critical overview of the genre shows that, far from being only a royal panegyric, masques often voiced complex political issues. The spirit and principles of this translation are also put forward : the aim was to express both the ideological and historical outdatedness of these texts (especially by translating into rhymed Alexandrine verse the iambic pentametres of the main masque – the panegyric part proper), but also their more modern dimension, especially in the comic passages of the antimasque. Lastly, there are many chronological, biographical and iconographical documents appended to this volume. The second volume includes the English text and French translation facing each other, accounts for the choice of the editions used (Herford & Simpson, Orgel), presents the historical context and main thematic lines of each masque, and provides numerous notes, taking into account the work of the previous commentators and the most recent critical contributions. This unprecedented translation aims at making Jonson’s masques available to the francophone community ; yet the updating work and interpretations offered in the substantial critical apparatus may prove useful to the specialists of the period

Full textThe poems written for court festivals in the second half of the Sixteenth century have long been considered unworthy of the attention of scholars of French literature. However, these colourful traces of famously splendid court festivities involved many of the poets of the generation of the “Pléiade”, remembered today mostly for its classic collections of poetry. Nonetheless, these poets also participated in the practice of composing impromptu poetical pieces, which effectively made them the masters of court entertainment. These poets did not restrict their activities to their study or their “librarie”, but designed the sets and organised the saging of their masques – sometimes even playing some of the parts – and collaborating with other artists. The part played by the poet in these festivals is far from being solitary: it is essentially collaborative. His verses are not a mere ornament of the festivities, but are their very life, giving them shape and colour. Poetry plays a part in all aspects of the festivals at court: it is sung, but also inscribed on elements of the décor and showered down on the monarch when he arrives. In this sense, poetry is the “légende” of the celebrations, serving as a caption and as a way creating a legendary, sacred and dramatic representation of power. This poetry also participates in the aesthetic of the maraviglia characteristic of manneristic and baroque festivals. The poetic genres that they involve (masques, mummeries, cartels etc.) mutually influenced each other and developed as hybrid forms which were grew out of the intertwining of many different poetic traditions

Full textDealing with the iconography of fetes in the Renaissance means investigating into humanism and the neo Platonist currents of thought which influenced the artists of the time and led to the syncretism of arts in court celebrations.In the ephemeral art of revels -entries, masquerades, balls and ballets- the costumes of mythical figures from the Bible or the Antiquity were then brought back to the fashion of the sixteenth century with a playful twist and updated through the new themes inspired by the Great Explorations, such as the contrast between the exoticism of the New World and the traditions of the Old World. Along with those codes, the establishment of a new decorum allowed the evolution of the notion of performance and of the places best suited for theatricals. Social and political issues of a time fraught with religious wars, alliances and peace, also contributed in paving the way for such changes.Celebrations thus proved the quintessential instrument of the assertion of royal power, which turned them into vectors of communication, not to say communion. Both sumptuous and innovative, they foreshadowed the magnificent fetes of the following centuries

Full textJumping high necessitates complex motor skill, who requires different strategies of motor control. Mass-spring models are usually used to describe human or animal locomotion, like jumping tasks. Two main questions are asked: Is leg stiffness used to regulate human behavior ? Does a signature between athletes performing in varied sports exist? In an experiment on running single-leg jump performed by different athletes in varied sports, we have shown that a minimal value of leg stiffness is necessary to jump high, but there is no significant correlation between stiffness and vertical jump performance. During drop jump, it is possible to regulate leg stiffness through instructions about the knee flexion. These results confirm the idea that jumping high could be performed with different levels of stiffness. A signature of athletes performing in varied sports has been confirmed during running single-leg jump and counter-movement jump. These jumps could be captured by a temporal and a force component and allow to differentiate athletes from their sport origin (volley-ball, basket-ball, hand-ball, Fosbury-flop et novices)

Full textResearch and development (R&D) in the pharmaceutical industry is a crucial step for the discovery of new drugs or biomarkers. The development of new innovative treatments is a key driver of progress in the management of many diseases, such as periodontitis or immuno-oncology. This thesis work is initially interested in the place of mass spectrometry imaging using a matrix-assisted laser desorption ionization source (MALDI-MSI) during the development of new drugs, followed by its evolution reviewed (matrices, instruments and software) before illustrating several developments made with this technology to improve the detection of the compounds of interest (drugs / biomarkers), but also the quality of the results (quality of the samples or the quality of the analyze) with a view to standardization. Also, the implementation of quality controls and the validation of the quantification method improves the quality of the results. These developments then help pharmaceutical industries in the R&D stages, allowing them to combine this technology with their arsenal, in order to save time and money during the development stages of new drug candidates

Full textThe replication of the defective parvovirus AAV depends on a co-infecting “helper” virus (HSV, Ad). We tried to precise the results of previous studies that had suggested that AAV could replicate without a helper virus in cells exposed to diverse stresses, but we never observed a clear AAV replication. Our data suggest that the replication previously described was due to the synergy between stresses and transforming viral factors. We then studied the interaction between AAV and its helper virus HSV-1. We first precised the helper functions provided by several HSV-1 factors a priori involved in AAV replication; we then purified and identified by MS/MS the cellular and HSV factors associated with Rep during AAV replication. We showed that at least 10 HSV-1 factors participate to its helper effect for AAV, and identified about 50 cellular factors potentially involved in AAV replication

Full textObesity - characterized by lipid accumulation in adipose tissue and in peripheral tissues such as liver and skeletal muscles - leads to metabolic dysfunction of these tissues. In the long term, although it is frequently reported an increase in lean mass, obesity is accompanied by a loss of muscle mass. Weight loss has a positive impact on comorbidities associated with obesity. However, when it was induced by dietary restriction, it may be associated with muscle mass loss. The association of physical activity to food restriction may limit muscle mass loss. Metabolically, muscle mass depends essentially on proteins turnover, i.e. protein synthesis and breakdown. Therefore, the aim of the thesis work was to characterize changes in muscle protein metabolism, especially changes in protein synthesis, during obesity development and weight loss induced by a low-fat-diet with or without endurance exercise. The first study has shown that there are two distinct phases in the development of obesity in rats. The first is associated with body weight and muscle mass gains and an increase in myofibrillar and mitochondrial proteins synthesis rate (FSR), specifically in glycolytic muscle tibialis anterior, in postabsorptive state. Oxidative muscle soleus was not affected. The second phase is associated with body weight stabilization, reduced muscle mass and a decrease in the mitochondrial proteins FSR in the tibialis anterior. The second study has shown that isocaloric low-fat-diet or the practice of regular endurance exercise do not prevent muscle mass loss induced by obesity, unlike the combination of both treatments. Exercise alone or associated with high-fat diet stimulates the FSR of myofibrillar proteins actin in tibialis anterior muscle, but exercise stimulates the FSR of myofibrillar and mitochondrial proteins in the oxidative muscle soleus only when it is associated with lipid restriction. In conclusion, this study has shown firstly that muscle protein synthesis in postabsorptive state and muscle mass are differently affected depending on the stage of obesity development, and, secondly that muscle protein synthesis in postabsorptive state is differently affected depending on muscle typology. On the other hand, exercise has a beneficial effect on muscle mass and protein synthesis, but this "anabolic" effect is limited by the high-fat, high-sucrose diet. To transpose these data in humans, a clinical study that examines the effect of weight loss induced by bariatric surgery on muscle protein metabolism has been established and is currently underway

Full textThe thesis sets itself in the framework of the study of core-collapse supernovae (CCSN). First, the modeling of the composition of the core of a massive star during its collapse has been investigated. To this aim, we have built a new treatment of the nuclear statistical equilibrium starting from a single-nucleus approximation equation of state (Lattimer and Swesty, LS). This allows a more realistic description of the nuclear distribution inside the core and, more specifically, to quantify the role of the nuclear masses. The distributions obtained with the original mass functional (LS) and those obtained with HFB-24 and DZ10 mass models have been compared for several thermodynamic conditions of a typical CCSN trajectory. The differences in the composition could lead up to ∼25% deviations in the electron-capture rate, thus showing the need to identify a proper mass model to use in CCSN simulations. Therefore, we performed high precision mass measurements in the nuclear mass region of interest, via a double Penning trap at the IGISOL facility (Jyväskylä, Finland). Five new mass excess were determined for the following nuclei : 69m,70Co, 74,75Ni and 76mCu. The precision has been improved for five others : 67Fe, 69Co, 76,78Cu and 79mZn. Finally, we have confirmed the values obtained by recent studies for 77Cu and 79Zn. The experimental values of the nuclear gaps for Z=28 and N=50 have been compared with the results predicted by DZ10 and HFB-24. The latter model better reproduces the evolution of these gaps. Therefore, HFB-24 was used in our new statistical treatment, that we implemented in an existing CCSN hydrodynamical simulation. We have observed a moderated impact of the mass model on the composition of the collapsing core. Moreover, we found that the differences in composition have small effect on the collapse dynamics, which appears to be more sensitive to the electron-capture model. Further studies should thus focus on this parameter

Full textCombustion of carbon black (CB) in the crucible of a thermobalance is controlled by both carbon reactivity and oxygen transport from the oxidizing flux to the surface of the bed and within the porous bed.The experiments conducted by changing the mass of CB showed that the oxygen concentration can fall to zero before the bottom of the bed. Thus, at a given time, only a part of the bed is burning. This mass, called critical mass (mc), depends to temperature. It went from 35 mg at 570°C to 17.5 mg at 650°C.An oxygen gradient is thus established in the bed. The Modelling of the internal transport of oxygen showed that the Fick diffusion is a good approximation to represent the transport.Advices to correctly extract a kinetic constant using thermogravimetric experiments are given. The procedure is adjusted depending to the precision desired.Thus, the use of low masses to best reduce the mass and exothermic reaction effects is strongly recommended. The influence of stagnant gas can be reduced by using crucibles with very low height, or by placing the sample closest to the mouth of the crucible by filling the bottom of the crucible with an inert material

Several Sb and Sn known isotopes beyond the Z=50 and N=82 shell closures will be briefly presented in the first chapter, aswell as some of the problems arising from the current shell model descritpion of nuclei in this region. Reader will also find in the same chapter a brief description of the most important tools needed to understand such calculations. Excited state of 136Sb have been populated at the Institut Laue-Langevin (Grenoble) through thermal neutron-induced fission on a 241Pu target. Fission fragments produced were separated with the Lohengrin mass spectrometer. Conversion electrons and gammas from 136Sb were measured and confirmed the previously proposed schemed. A new 31(7) ns isomer has been measured and assigned to the 4- state. Details of the experiment and analysis are presented in the first part. The second part is devoted to the 136,138Sn isotopes, produced via in-flight fission of 238U on a 9Be target at the RIBF of the RIKEN (Tokyo). Mass separators BigRIPS and ZDS allowed separation and identification of produced fragments, before implantation in the higly segmented silicon detector WAS3ABi surrounded by the germanium array EURICA. The first energy measurement of the 6+ -> 4+, 4+ -> 2+ and 2+ -> 0+ transitions has been performed for each of the 136,138Sn isotopes, aswell as an 46(7) and 219(58) ns half-life for the 6+ state of the 136Sn and 138Sn respectively

Full textAfter the beginning of a fire in a closed room, the oxygen rate in the atmosphere decreases. This implies an incomplete combustion and unburnt gases production. These ones may accumulate in the room or in ventilation pipes, and, after mixing with fresh air, auto-ignite. This could trigger a thermal accident such as backdraft. This present work, conducted for AREVA, aims to analyse this hazard and provide some methods to predict and prevent it. First, a bibliographical research, was carried on to define a mixture’s auto-ignition parameters. This study was based on Frank-Kamenetskii’s model: after establishing the energetics balance between the heat produced by combustion, and the one consumed by conduction, an auto-ignition critical parameter, δC, was defined. It reunites the system’s geometry, temperature (or the room temperature) and composition.Then, the High Density Polythene degradation in a Controlled Atmosphere Cone Calorimeter was studied. The effect on the material’s degradation of under-ventilation and of the energy brought has been tested through the oxygen concentration in the atmosphere and the incident heat flux.During this work many different gas mixtures were analyzed. On the ground of δC formula, the final step was to set the volume, through the radius (characteristic size of the system), as an auto-ignition parameter. Making the concentration of each combustible varying between the LFL and UFL and imposing the temperature allowed to predict this hazard

Full textPolymeric membranes can be prepared using different phase separation processes (i) temperature induced phase separation (TIPS) (ii) dry cast (iii) non solvent induced phase separation (NIPS). In the latter case, the demixion of the solution can be achieved by a direct immersion in a non solvent bath (wet process) or by the exposure to non solvent vapours (vapour induced phase separation process - VIPS). The aim of this work was to study the mass transfert phenomena (solvent evaporation and non-solvent absorption) during the VIPS process. Different polymer/solvent/non-solvent systems were studied. Dynamic characterizations were conducted using gravimetric measurements, and spectroscopic methods (near infrared and raman spectroscopy). Numerical simulation of the mass transfers was realised in order to draw with time the concentration profiles in the bulk polymer solution. Numerical results have been validated by in-situ experimental data et discussed in relation with the obtained membrane morphology

Full textAlterations of physiological functions and notably of immune function are a hallmark of ageing. So we interested of two oxidative modifications with age, protein glycation (AGE) and conjugation of proteins to lipid peroxydation products (4-HNE), in peripheral blood lymphocytes (PBL). Proteins from young and old donors were analyzed by a proteomic approach. Proteins are separated by 2D electrophoresis and then blotted on a nitrocellulose membrane before to be analyzed by Western Blot with antibodies raised against AGE and HNE. Thus, we detected 7 spots modifîed by glycation with age and 7 spots HNE-modifîed with age too. Some of them were identified by mass spectrometry: they are proteins from cytosqueleton and proteins implicated in transduction pathways or in proteins control quality. In the second part of this work, we have studied the effects of 4-HNE on structure and function of the protein chaperon Hsc70 (one target of 4-HNE identified ex vivo). Concerning thé amino acid composition of Hsc70, after 16h of incubation of Hsc70 with 100 μM of 4-HNE, 2 cysteines over 4,2 histidines over 7 and 4 lysines over 54 are modified. Six of these residus were identified by mass spectrometry. They are in N terminal ATPase domain and in the C-terminal oligomerization domain of Hsc70. However, the ATPase activity of Hsc70 is not altered. At the contrary, the abilities of Hsc70 to bind protein substrate and to oligomerize are decreased. At last, like native Hsc70, Hsc70 modified by the 4-HNE is not a better substrat for 20S proteasome but its effect on the proteolysis of casein, one substrate of 20S proteasome, is different

Full textLn freshwater systems, metals are known to have a particular affinity for the solid fraction. Consequently, the latter may constitute a potential toxic risk for aquatic organisms. Sustainable management in the Seine River Basin requires characterizing particulate carrier phase of metals in order to determine its geochemistry, identify urbanization impact of the Greater Paris Region and deduce the sources of metals and their mobility. To achieve these objectives, suspended particulate matter (SPM) was studied in relative to the water column and zoomed upon until the metal's molecular environment. Ln agreement to previous studies, lead (Pb) was associated mostly to the solid fraction while nickel (Ni) was found mostly in the dissolved phase. As for the rest of the metals such as cobalt (Co), chrome (Cr), copper (Cu), manganese (Mn) and zinc (Zn), there seems to be a shared preference for the solid and dissolved phase. Downstream Paris, not only did solid lsolution partitioning of Co, Cu and Ni decrease, but also temporal variation of the partitioning during monthly observations, indicating more stable forms of carrier phases. As for cadmium (Cd), Pb and Zn, it was their oxidizable fraction in the SPM that increased downstream, particularly associated with iron oxides (FexOy). An identified source of these oxides would be the bed sediment. Ln the case of intense storm episode, the combined wastewater system would overload and a large volume of direct wastewater would overflow to the Seine River. Calculation using a mixing model suggested that bed sediment contributed from 30-50% of particulate metal found in the overflow plume. This is a relatively high contribution compared to the 10-30% of particulate metal which would originate from the overflow itself. Besides iron oxides, reduced environment in bed sediment and CSO would also contribute to ZnS found in the water column. These ZnS are identified as single or clustered amorphous nanoparticles. This species is rather stable as they are found to persist in oxic environment

Full textAbstract : sFlt1 appears to be a good biomarker of preeclampsia (PE). The impact on pregnancy outcomes of close monitoring of women identified as "at risk" at 24 and 29 weeks of gestation (weeks) by a high level of plasma sFlt1, was evaluated in a randomized controlled trial (MOMA). 939 nulliparous women were included in 2 arms (sFlt1 known or unknown). Our results do not show any improvement of pregnancy outcomes and suggest that the inefficiency of the intervention (close follow-up) is the most likely cause. Thus, routine sFlt1 screening to predict the occurrence of PE does not seem useful until effective treatment is available. Abnormalities of placental steroidogenesis have been associated with PE. 90 samples from the MOMA cohort divided into three groups (25 intra-uterine growth retardation (IUGR) without PE, 25 PE and 40 controls) were used to assess by the reliable GC / MS technique, the steroid profile (between 24 and 29 weeks)before the development of clinical signs. In the PE group, we showed abnormal androgen aromatization, by calculating the estradiol/Δ4-Dione ratio (blood), and a lack of expression of placental aromatase. Similarly to the significantly low levels of pregnenolone sulfate found, this lack of aromatization seems specific to PE as they are not found in the IUGR group. These modifications are part of a deregulation of the overall steroid profile. In the PE and IUGR groups, we observed an excess of 20α-dihydroprogesterone (20α-DHP) and a significantly high 20α-DHP/Progesterone ratio. Sex steroids share common signaling pathways with angiogenic factors which easily integrate the "steroidogenesis abnormalities" hypothesis in the current concepts in the pathophysiology of PE. Links between disturbances of steroidogenesis and preeclampsia are discussed

Full textThe structuration of biotic communities is generally caused by an interplay between stochastic and deterministic processes. Species sorting, i.e. environmental filtering coupled with biological interactions, and dispersal processes are particularly important divers of communities, however, their relative influence are constrained by the effects of spatial scale and therefore poorly understood. Quantitative multi-scales approaches are thus recommended to better understand how local and regional processes affect communities. However, few studies have actually implemented quantitative scale-explicit frameworks to explore such relationships. This is one of our aims here, to quantify the relative contributions of local community assembly processes vs. stochastic processes in driving benthic diatom communities, and to assess how spatial scale and anthropogenic disturbance interact to dictate which driver dominates. Using French and US databases encompassing more than 4 000 spatially distinct localities, this work provides strong evidences stating that nutrient supply mediated community structuring whatever the scale considered. Nutrient enrichment was associated with an overall decline in diatom beta-diversity and a shift in assembly processes from species sorting to dispersal. Dispersal limitation and mass effect are the two major dispersal processes acting on diatom communities. While dispersal limitation can be detected by experimental or modeling techniques, mass effect is more challenging to detect as it can allow species to persist in unfavorable habitats, i.e. far away from their environmental optimum. Here, we developed an innovative and robust method for the detection of this process for passive dispersers, such as diatoms. Beyond its importance in the taxonomic homogenization, causing extensive impairment of freshwater ecosystems, mass effect is also evoked for its potential impact on bio-assessment methods. Our results largely supported the idea that mass effect may induce a biased evaluation of water quality, since taking into account this process for the calculation of the Biological Diatom Index leads to a more acute assessment of river ecological status. We then advocate for a better integration of spatial mechanisms in any diatom-based indices, and by extension in any biotic index based on passive dispersers

Full textPlantain is a fruit commonly consumed in Congo - Brazzaville in its cooked form, as an accompaniment. The process of deep frying plantain is a widespread practice, often poorly mastered, given the prolonged use of frying oils, leading to the formation of compounds harmful to health. Indeed, for a number of years, the consumption of local oils (soybean, palm) and their degradation after heating are cause of major concern for consumer safety. The objectives of this study were to investigate the influences of the deep frying process applied on the Musa AAB plantain of "harton" variety, maturity level 7, as consumed in sliced form. We initially applied response surface methodology (RSM) to the deep frying process to determine the influence of three parameters (time / temperature / quantity) on different responses (color, hardness, oil uptake and water content) according to the type of oil used (soybean, palm, Frial oils). Once optimal conditions were obtained from the plantain in domestic conditions, the study focused on the evolution of frying oil stability, by monitoring physicochemical parameters of the degradation of the aforementioned (total polar compounds, free fatty acids, primary and secondary oxidation products). Analyses of color, crystallization point and viscosity, were added to the study and helped establish the optimal duration of use for these oils depending on the quantity of plantains fried. Lastly, the mechanisms of water transfer and oil uptake in the matrix has been studied and modeled according to temperature, thickness and immersion time

Full textPersistent Organic Pollutants (POPs), largely present in the environment via sewage wastewater (WWTP) and anthropogenic activities are a source of contamination of the aquatic environment. The environmental risk assessment of these compounds involves their specific and quantitative chemical analysis and estimation of their origin next to the contaminated areas. This study was a qualitative and quantitative analysis, internationally, for about thirty organic compounds representative in terms of use and relevant in terms of environmental impact. The approach used incorporates a detection step and a step for evaluating the toxicity of the compounds targeted to estimate their level of ecological risk. The detection of these compounds in the sediment matrix required the development of a Soxhlet extraction method and the development of a method of detection by GC-MS. Validation of this method allowed to carry out a sampling campaign of 54 stations spread over four watersheds (Arc, Huveaune, the Durance, the Etang de Berre and Oued Medjerda), to assess the level of contamination by POPs. This work intends to carry out a guided sampling (before and after major works such as STEP, industries ...) sediments of different rivers in the Mediterranean area and study both infection rates and the origin of POPs. At the regional and international levels, the subject responds to a strong societal demand. Indeed, it is essential to characterize the quality of streams and to estimate their contamination. This work has allowed a consistent inventory level of contamination. The PAH analysis is done by gas chromatography-mass spectrometry (GC / MS)

Full textAs an answer to cycles of mass violence in Burundi, a transitional justice process has been opened. The Burundian case study presents some particularities among this kind of process. Whereas the Arusha peace and reconciliation agreement for Burundi in 2000 decided setting up two transitional justice instruments, a special court and a Truth Reconciliation Commission, the transitional justice process has not begun yet. Only National Consultations were organized in 2009. The negotiations and the mediation occurred during the ongoing war. There were no winners and no losers but just armed men who decided to discuss in order to conquer the power and then to keep it. That may explain why negotiations were so longer and staggered. A sort of consociativisme system was set up in Burundi as the model organization of power-sharing. Inside the politic game of power-sharing the peace-justice dilemma appears through instrumentalization of retributive justice which is assimilated to justice and the truth and pardon which claim referring to peace. Another particularity is found regarding numerous judicial and legal reforms relatively to children rights, lands conflict, electoral law or Criminal Code. On the eve of the implementation of the Truth Reconciliation Commission, the global nature of the transitional justice process is obvious. The Burundian context appears as an illustration of the extensive meaning of transitional justice which represents a justice in transition. The global nature of the matter is emerging through its temporal and disciplinary versatility. On one hand, transitional justice seems to be past justice, currently justice and future justice at the same time and on the other hand it may take several forms out of the official one, initially predicted. In a legalist and normative view, global nature of justice in transition might cause deadlock regarding the case of Burundi. In a systemic and multidisciplinary perspective, global nature of justice in transition reveals change capacities according to the case of Burundi. What really matter in such transitional justice process is relieving victims and perpetrators’sufferings which are undeniably linked and bringing answers to each protagonist of the crime as to the society with the permanent and ambitious aim of reconciliation

Full textMercury is a very particular element conferred by its high density and vapor pressure. It is a ubiquitous element in the environment and considered as global pollutant. Mercury is among the most hazardous environmental pollutants, given by its organic form, methylmercury (MeHg or CH3Hg). In natural waters, mercury is present at very low concentrations. For this reason, most analytical techniques do not achieve accurate direct measurement of Hg which necessitates preconcentration to meet their limit of detection. The first part of this study focuses on the development of analytical methods for the measurement of mercury by solid phase extraction. Two analytical methods have been developed; one based on the anion exchange mechanism using ICP-MS (Inductively Coupled Plasma Mass Spectrometry) and the other one based on the solid phase extraction of mercury using 5-phenylazo-8- hydroxyquinoline and detection by CV-AFS (Cold Vapor Atomic Fluorescence Spectroscopy). Part of this work also includes the distribution and biogeochemical behavior of mercury in rivers of the Deûle and Lys (Northern France). The results have showed high concentrations of total mercury (HgT) in the Deûle contaminated by a former smelter "Metaleurop". The concentrations of HgT measured in the Lys are much lower. Although Deûle sediments are highly burdened with HgT as compared to Lys sediments, much higher percentage of methylmercury is found in Lys River. Suspended particles are the major Hg carrier phase and transporters of Hg pollution from Deûle to Lys River

Full textBeing able to adjust food intake according to the energy density of food is one way to self-regulate energy intake and maintain a healthy energy balance. In the context of the prevalence of overweight in children, it appears crucial to identify early factors that may affect caloric adjustment abilities. During the complementary feeding process, the amount consumed, and in turn, the caloric adjustment abilities depend in part on the quality of the caregiver-infant interaction. An epidemiological study suggests that caloric adjustment abilities might deteriorate around one year old; a time when the transition from baby-foods towards adult like foods occurs in the infant diet.In this work, we performed a laboratory-based assessment of the infants’ caloric adjustment ability by adapting the preload paradigm. By using a longitudinal approach, we first described the developmental changes in infants’ caloric adjustment ability between 11 and 15 mo. Then, we explored whether some factors related to the infants’ characteristics, the type of foods consumed or the mother-infant interaction during the meal were linked to the caloric adjustment ability.We showed that, at 11 and 15 mo, the infants under-compensated their energy intake after consuming a food preload more or less caloric. However, we observed large inter-individual variation in this ability. The level of caloric adjustment was not better when considering the total food intake during the 24 h following the food preload consumption. At 11 mo, infants had better caloric adjustment ability when the mother adapted the spoonful pace to the spoonful weight content; this dynamic during the meal could reflect a responsive feeding. At 15 mo, the infants exhibited a volumetric adjustment rather than a caloric adjustment. Regardless of the studied age, no significant links were found between the infants’ feeding experience (milk and complementary foods) and their caloric adjustment ability. Regarding the developmental changes, we observed that the infants’ caloric adjustment ability deteriorated from 11 to 15 mo. The more this deterioration, the more the infants were perceived as ‘attracted by food’ by their mothers. Moreover, the more this deterioration, the more the z-BMI increased between 11 and 15 mo, and the higher the z-BMI was at 24 mo. In addition, the more the infants were exposed to a wide range of energy density for the vegetable-based recipes between 8 and 11 mo, the lower their z-BMI was at 8 and at 11 mo. This work highlights that caloric adjustment ability is associated with various early factors related to the mother-infant dyadic functioning and the infants’ weight status. These results open up a new research field to understand the causality underpinning these links. In fine, this would allow to assist parents to support an optimal development of their infant’s caloric adjustment abilities during the key period of the first 1000 days

Full textCriminal qualification is conventionally considered as a sub-category of the legal qualification and shares with it the same definition and the same characteristics. It is actually conceived as an intellectual operation and, as a consequence, thought out in its own dimension. This qualifying operation appears as a translation of the facts in law by the use of legal language. The researcher who intends using this qualification process as his purpose of study is necessarily confronted with subjects that are unfamiliar to him such as linguistics and cognitive psychology. To circumvent the difficulties inherent to these subjects, it is possible to make a paradigm shift to the approach of the criminal qualification. It can be forseen in the terms of the process. This concept allows to give the criminal qualification its institutional dimension and to consider it as the product of micro-decisions of actors in a network. Their respective actions form different stages of this complex process which ultimately leads to the criminal definition of a situation. This research proposes to implement the concept of process of criminal qualification in mass litigation, areas that are favorable to the observation of qualification practices. The analysis of these practices observed from empirical work has permitted to verify the hypothesis that criminal qualification is formed through networking. It therefore appears as the product of various actors/participants dealing with objectives and institutional constraints. From the concept to the exact qualification, criminal designation is the result of a multifactorial process

Full textGiven the limits of the international literature on the environmental disparities in obesity prevalence (focused on the residential neighborhood) and considering the lack of empirical studies conducted in France, we were interested in the relations between, on the one hand, the characteristics of residential and professional neighborhood characteritics and the work economic sector, and on the other hand, two body fat indicators: the Fat Mass Index (FMI) and the percentage of Fat Mass (%FM). Then we compared the effects of the work economic sectors on several cardiovascular risk factors. Finally using a longitudinal study, we evaluated the links between socioeconomic variables and the evolution of the anthropometric parameters among participants of the RECORD Study. Simultaneously, our methodological objective was to explore the attrition biases due to missing data in longitudinal studies.To conclude, we could by those empirical works highlight the effect of the individual and the residential characteristics, and the work economic sectors on the accumulation of body fat as well as on cardiovascular risk factors. Regarding the methodological part of this work, firstly we were able to take into account in the analysis the residential geographical environment commonly considered. Secondly, differentiating us from the transversal literature on the social determinants of obesity, we show that depending on the missing data mechanism, the statistical methods commonly used can not circumvent the potential bias introduced by attrition in longitudinal analyses

Full textSilicon carbide (SiC) has higher critical electric field for breakdown and lower intrinsic carrier concentration than silicon, which are very attractive for high power and high temperature power electric applications. In this thesis, a new 3.3kV/20A SiC-4H JFET is designed and fabricated for motor drive (330kW). This breakdown voltage is beyond the state of art of the commercial unipolar SiC devices. The first characterization shows that the breakdown voltage is lower (2.5kV) than its theoretical value. Also the on-state resistance is more important than expected. By means of finite element simulation the origins of the failure are identified and then verified by optical analysis. Hence, a new layout is designed followed by a new generation of SiC-4H JFET is fabricated. Test results show the 3.3kV JFET is developed successfully. Meanwhile, the electro-thermal mechanism in the SiC JFETs under short circuit is studied by means of TCAD simulation. The commercial 1200V SIT (USCi) and LV-JFET (Infineon) are used as sample. A hotspot inside the structures is observed. And the impact the bulk thickness and the canal doping on the short circuit capability of the devices are shown. The physical models validated by this study will be used on our 3.3kV once it is packaged

Full textContinuous Positive Airway Pressure (CPAP) is the first-line treatment for moderate to severe Obstructive Sleep Apnea (OSA) syndrome. Unintentional leakage and its annoying consequences are the most frequently reported adverse effects. However, the causes of unintentional leaks are poorly understood. This thesis aimed at identifying the determining factors of unintentional leaks during CPAP treatment in OSA and developping innovative strategies for the selection of masks and leaks management.In our systematic review we have arbitrarily split the potential determining factors of leaks into two categories: 1) the non evolving factors overnight: nasal obstruction, age, high body mass index, central fat distribution and male sex were potential contributing factors associated with unintentional leakage. The oronasal mask was associated with higher unintentional leaks than the nasal mask; and 2) the evolving factors overnight such as sleep stages, body position, mouth opening and CPAP level. We studied these evolving factors in 74 OSA patients treated with auto-adjusting CPAP: mouth opening, CPAP level, body position and REM sleep were independently associated with an increased risk of unintentional leakage. We also highlighted that oronasal masks reduced the risk of unintentional leaks in cases of mouth opening and REM sleep. Since the CPAP level is a determining factor of leakage we evaluated through an ancillary analysis of a randomised controlled trial whether the type of CPAP (fixed versus auto-adjusting) could contribute to leakage. In this study, there was no effect of type of CPAP on leaks or the type of interface used after 4 month of treatment. Finally, in 214 patients, we prospectively evaluated the relevance of the Nasal Obstruction Syndrom Evaluation (NOSE) score as a simple decision-making tool to guide the choice of mask during CPAP initiation. A NOSE score > 50/100 at the initiation was independently associated with the use of an oronasal mask at 4 month. This score could be a simple tool for the objective assessment of nasal obstruction related to symptoms, facilitating the choice of an appropriate interface. As a conclusion, during this thesis we have developed a novel methodology to characterise and analyse the overnight determinants of unintentional leakage. Its clinical application could lead to individualised corrective measures of leaks. Further studies are needed to prospectively validate this model, as well as the clinical relevance of the NOSE score to guide the choice of mask in daily practice
