Full textContext: the main function of HDLs is the reverse transport of cholesterol from the tissues back to the liver, thus conferring a cardiovascular protective role. HDL also DISPLAY other endothelioprotective properties, in particular anti-inflammatory, antioxidant, anti-apoptotic, anti-infectious and antithrombotic effects. During certain states of chronic inflammation, such as atherosclerosis, changes in HDL function and structure have been previously described, which can have negative consequences on morbidity and mortality. The objective of this thesis was to investigate the structural and concentration changes occurring in human sepsis a model of exacerbated acute inflammation. In addition, we tested the effects of injecting human reconstituted HDLs in several experimental sepsis models. Results: first part, by comparing two exacerbated inflammatory conditions, we showed that the plasma HDL concentration was drastically decreased in patients at the acute phase of sepsis while it was not modified in polytrauma patients. A second part focused on comparing patients in septic shock and non-septic ICU patients. We confirmed these differences in HDL concentration. In addition, septic patients had more large HDL particles compared to control patients who had more small functional particles. A kinetic study of HDL concentration in 205 septic ICU patients showed a drastic decrease at the acute phase and then an increase at patient's recovery without returning to the basal concentrations observed before the hospitalization. HDL concentration was associated with certain morbidity criteria (SOFA score, days alive without mechanical ventilation), but no link to mortality was found in this work. A proteomic analysis of plasma from septic patients found a drastic decrease in many apolipoproteins compared to plasma from non-septic patients. Finally, the injection of human reconstituted HDLs in three mouse models of sepsis showed a decrease in mortality, as well as a decrease in many markers of inflammation and bacterial concentrations in both plasma and tissues. Conclusion: during sepsis, there are both quantitative and qualitative modifications of HDLs with a significant decrease in their concentrations, but also increased particle size and changes in the composition of these particles. The quantitative aspect alone does not seem sufficient to predict patient outcomes; evaluation of HDL dysfunction could represent a better biomarker. In addition, injection of functional HDL has proven its effectiveness in several mouce models. Further studies to characterize these dysfunctions are needed before completing a randomized trial evaluating therapeutic injection of HDL during sepsis in patients

Full textWith the rise of globalization, changes in the working environment are greater than ever and more difficult to foresee. The majority of today’s working population is compelled to change jobs often, necessitating retraining, perhaps more than once, in the course of professional life. As a result, the support provided by career advisors during these various transitions should evolve to take into account all areas related to the professional sphere (familial, personal and social) as well as the individual’s situation and development. However, the methods to achieve this remain to be defined. The main aim of this dissertation is to suggest methodological solutions to meet the goals of lifelong guidance. To this end, it proposes constructionist career counseling methods based on the Multistage Investigator of Social Identity (Zavalloni & Louis-Guérin, 1984), which is routinely used in social psychology studies. This method has been adapted for the context of professionals in career transition and computerized as the Multistage Investigator of Social Identity for counseling (MISIc). Its potential was then tested on recipients of an in-depth skills assessment (bilan de compétences approfondi or BCA) as part of a career review. The MISIc allowed a better grasp of the information required for a comprehensive understanding of the issues affecting professionals in retraining. An experimental protocol was then used to evaluate the performance of the MISIc, revealing that its use had an effect on the ability to develop a career plan during a career review. Other objectives were then added to the development of the MISIc, such as the modeling of professional transitions and the evaluation of a career advisor’s methods. During career transitions, events arise in the professional’s environment that can impact their self-concept and their self-esteem in both linear and nonlinear ways. The use of idiographic protocols, combined with time series and verbatim analysis, quantitatively and qualitatively identify factors that impact the development of a career plan. In conclusion, new methods should continue to be developed in order to meet the global and contemporary challenges relating to the adaptation of individuals to their personal and professional situation, with, as a corollary, a dedicated academic field and a well-defined set of professional methods

Full textTo day's educators are being questioned by the increasing amount of literature and talk about evaluation. School authorities themselves are busy setting up evaluation processes on a wide scale at the end of the third grade. In this study, within the framework of our own practice, we have done some research on our own evaluation processes in order to fulfill the needs of our pedagogical action which we want to be both active and cooperative. We have found that only formative evaluation answered that purpose. The learner should be helped, informed and assisted all through his her school years. He she should never be eliminated, selected, ranked if we want to reduce inequalities at school. To do so, we had to implement our evaluation processes in many ways and make them function. What we have achieved will be described in our thesis. It means that teachers have to be self-trained too, to reach that goal and the theoretical feedback involved in the process lead us to unravel and face lift the theoretical models. These models are being criticized nowadays by many people who wish to limit their scope by giving formative evaluation a logical bias which has no place there in

Full textThis thesis is part of a study that explores automatic transcription potential for the instrumentation of educational situations.Our contribution covers several axes.First, we describe the enrichment and the annotation of COCo dataset that we produced as part of the ANR PASTEL project.This corpus is composed of different lectures' videos. Each lecture is related to a particular field (natural language, graphs, functions ...).In this multi-thematic framework, we are interested in the problem of the linguistic adaptation of automatic speech recognition systems (ASR).The proposed language model adaptation is based both on the lecture presentation supports provided by the teacher and in-domain data collected automatically from the web.Then, we focused on the ASR evaluation problem.The existing metrics don't allow a precise evaluation of the transcriptions' quality.Thus, we proposed two evaluation protocols.The first one deals with an intrinsic evaluation, making it possible to estimate performance only for domain words of each lecture (IWER_Average).The second protocol offers an extrinsic evaluation, which estimates the performance for two tasks exploiting transcription: information retrieval and indexability.Our experimental results show that the global word error rate (WER) masks the gain provided by language model adaptation.So, to better evaluate this gain, it seems particularly relevant to use specific measures, like those presented in this thesis.As LM adaptation is based on a collection of data from the web, we study the reproducibility of language model adaptation results by comparing the performances obtained over a long period of time.Over a collection period of one year, we were able to show that, although the data on the Web changed in part from one month to the next, the performance of the adapted transcription systems remainedconstant (i.e. no significant performance changes), no matter the period considered.Finally, we are intersted on thematic segmentation of ASR output and alignment of slides with oral lectures.For thematic segmentation, the integration of slide's change information into the TextTiling algorithm provides a significant gain in terms of F-measure.For alignment of slides with oral lectures, we have calculated a cosine similarity between the TF-IDF representation of the transcription segments andthe TF-IDF representation of text slides and we have imposed a constraint torespect the sequential order of the slides and transcription segments.Also, we have considered a confidence measure todiscuss the reliability of the proposed approach

Full textExcessive daytime sleepiness represents the major complaint of patients with obstructive sleep apnea (OSA). As a result, daytime vigilance is the most frequently examined component of attention in this disorder. The overall aim of this work was to establish the depth of attention deficits in OSA patients, in order to investigate whether sleepiness alone could explain cognitive deficits in these patients. Our results show that all attentional functions were altered, vigilance but also selective and divided attention as well as executive control of attention could be specifically altered. In addition, our work in a real automobile driving setting showed that OSA patients exhibited a marked increase in their reaction time while driving and that these performances were correlated with a laboratory setting divided attention test. Our findings indicate that OSA patients suffer from a multiple attentional deficit which does not implicate daytime vigilance exclusively

Full textInternal assessment is not often studied as a form of assessment although it is the teacher daily school activity. This thesis focuses on the most explicit part of this assessment i.e. all the tasks given to the pupils by their teacher in order to assess them. These tasks are used for evaluative judgment written in the « school report book». More precisely, we study this assessment validity depending on three distinct issues: a conformity issue that allows us to understand how assessing may fulfill the institutional specifications; a psycho-didactics issue that allows us to see how each task is likely to fulfill the assigned goals' or not; a didactics issue that allows us to grasp how the tests may conceptually cover the concerned disciplinary fields. This thesis explores internal assessments in French and Mathematics conducted by 1st grade teachers during the first and third terms. We particularly focus on reading, numeracy and arithmetic that are subfields with high socio-educational stakes. In order to examine the first issue, we explain the reference frameworks used by teachers when giving the test. French school programs are central in this area. We investigate how those reference frameworks and school reports are linked. It shows how assessment conforms to the academic institution. When focusing on our main issue, the psycho-didactic one, we emphasize for each task on the elements that could have been missed by the conceptual analysis of the task but yet could turn out to be key factors in the pupils answering behaviors. It means a new reference framework needs to be accounted for: the psycho-didactic approach brings the analysis tools for each task and for the potential cognitive functioning of the pupils who perform those tasks. In order to construct the validity analysis of the test from our third issue (test cover validity), we point out the didactic (or epistemo-didactic) frameworks that allows us to analyze the content of the tests given by each teacher. In combining the psycho-didactic and didactic approaches of assessment validity, we are able to conduct a double analysis, a global one and a local one, of both tasks and tests. The validity of a test depends on the validity of its tasks. The results mainly show that the tasks validity and the tests validity are often not ensured, which leads to question the value of evaluative judgment following the assessment. This advocates for a validity analysis combining a didactic approach of the test content to a psycho-didactic approach of the tasks

Full textWithin the general framework of simultaneous engineering, the work presented in this PhD thesis concerns the maintainability evaluation of a mechanical product during its design. Thus, our objective is to identify a method and tools enabling the maintenance expert to evaluate and measure the maintainability of the future product, and all this as soon as possible in the design process. We propose a redefinition of the maintainability criteria according to a hierarchical structure with three levels; we thus introduce the concepts of elementary criterion and under criterion of maintainability. Then we have presented a model of design data which makes it possible to preserve in the final index of maintainability the uncertainty and inaccuracy of initial design data, it is also possible to compute a confidence index of for the evaluation. In order to evaluate the maintainability index we have proposed an approach integrated in advanced CAD systems, thus simplifying the exchange of information between the maintainability evaluator and the designers. The numerical value of the maintainability index is determined by the aggregation of several maintainability criteria. We drew up the specifications for a product maintainability evaluation tool at the design stage; this tool is interfaced with an advanced CAD system. Finally we presented the application of our evaluation method in the case of redesigning an engine dedicated to model making

However, what is the quality of the measured data and what are the impacts of poor data quality on the objectives pursued during real-time water quality monitoring? Therefore, this master thesis proposes automatic data quality assessment tools to tackle this issue. These tools are general and simple, which means that they can be applied to any type of water and that they are based on easy-to-implement univariate methods. Following the application of these tools, data quality will be improved and known as such and will allow to better achieve the objectives of a real-time water quality monitoring project. The application of these tools is demonstrated on data collected during real-time water quality monitoring of an urban river performed using a monEAU station.

Full textIn a global change context, ecosystems are subjected to more and more severe human pressures. In this context, optimizing the biomonitoring of natural ecosystems has become a major scientific, political and societal issue. In the early 2000th, most of the freshwater bioassessment methods did not succeed in fulfilling the requirements of the European Water Framework Directive, for efficiently evaluating the ecological status of rivers with the main objective to maintain or to reach the good ecological status for all the water bodies. In the same time, a major advance in community ecology was the explicit consideration of the biological and ecological attributes of species (i.e. their ?traits?) to better explain the role of habitat characteristics in community assembly. The main goal of this PhD work was to establish how trait-based approaches, at different biological scales, could enhance the bioassessment of French streams. We have first focused on the utilization of potential bio-ecological traits of macrobenthic communities for (i) evaluating the ecological quality of rivers, (ii) assessing the risk of significant alteration of benthic assemblages by specific pressure categories and (iii) appraising the human pressure-drived functional homogenization process in benthic communities. We examined the potential of new traits (derived from stable isotopy, stoichiometry and proteomics) for depicting the benthic invertebrate responses to 'simple' anthropogenic pressures (i.e. acidification and organic contamination). We have demonstrated that using potential bio-ecological traits efficiently enhances the ecological monitoring of wadeable rivers, at large spatial scale (e.g. on National survey networks). The stable isotope and stoichiometry analyses, when applied at reach scale, have allowed to link biological traits (i.e. diet and development) to ecological functions provided by macrobenthic communities, such as nutriment and organic matter flows in rivers. Finally, the proteomic analysis, performed along an acidification gradient, has brought out very interesting perspectives for the development of an integrative ?expert system? that early detects the biological effects of water quality alteration on benthic invertebrate assemblages

Full textThe Improvement of the therapeutic management of HIV-infected patients, reducing the causes of morbidity and mortality due to HIV and increasing the life expectancy of patients, yielded to an emergence of the issue of tobacco smoking. We have conducted our research around two axes; the main results are as follows. 1) Burden of tobacco smoking (frequency and complications). Smoking prevalence is higher among HIV-infected patients (51), compared to the general population (27%), and tobacco consumption continues to older ages, increasing the risk of tobacco-related complications. We also show that smoking cessation is beneficial in preventing bacterial pneumonia whatever the level of immunodeficiency. 2) Prevention of tobacco smoking. If 40% of HIV-infected patients are motivated to quit smoking, they face major obstacles such as high dependency with frequent co-dependencies and depressive symptoms. Nearly 90% of HIV-infected smokers motivated need a specialized medical management to quit smoking. We also show that smoking cessation attempts are frequent in HIV-infected patients and that they are not related to the severity of infection. These results enabled us to identify the most adapted preventive measures and to implement a randomized double-blind clinical trial aiming at evaluating the efficacy and safety of varenicline for smoking cessation in HIV-infected patients, with a systematic management of depressive symptoms

Therefore, the purpose of this study is to evaluate the ESP course (for the faculty of agriculture) by investigating the reasons behind the ineffectiveness of the ESP course. This evaluation process covers : the teachers performance, the learners, the designated syllabus and methods of teaching applied. This study is conducted on a sample of students and a sample of the English language teachers at the faculties of agriculture. The designated syllabus and the methodology applied in teaching are also investigated by means of class observations, and questionnaires addressing both teachers and students. The questionnaires cover the needs of the learners and their motivation, the syllabus, and the methodology

Full textLa première partie de ce mémoire propose un cadre conceptuel pour l'estimation des dommages comme élément d'aide à la décision, notamment dans une perspective économique intégrant le risque et l'incertitude.
La deuxième partie considère l'échelle élémentaire de l'habitat, et se base sur des enquêtes réalisées sur différents sites auprès des ménages sinistrés. Après une analyse de l'occupation des zones inondables, on caractérise les composantes du facteur humain, et en particulier les réponses à l'annonce de crue et à la montée des eaux. Ces réponses et leurs effets sur les dommages sont étudiés par des techniques d'analyses de données, qui intègrent d'autres facteurs significatifs.
La troisième partie du mémoire traite de l'estimation des dommages sur une aire géographique, par des approches de modélisation. À partir d'une analyse conceptuelle de ces modélisations, est défini puis développé un modèle informatisé d'estimation des dommages sur un secteur inondable. Ce modèle local exploite, selon des procédures descriptives explicites, toutes informations et expertises existantes. Il est mis en œuvre sur 245 secteurs, à partir d'une base de données constituée sur les grandes vallées du bassin de la Loire. Une procédure de simulation permet de quantifier les incertitudes sur les estimations de coûts, en analysant les contributions des différentes sources d'incertitude. À échelle régionale, on analyse les effets des cohérences spatiales des crues et des sources d'incertitudes.
La quatrième partie conclut sur les méthodes développées et propose des perspectives ultérieures de recherches.

Full textThis investigation aims at analysing teachers and students’ activity and is based on what they experimented for one scholar year of non-rated assessment. This study was carried out in the light of the scientific and technological research programme of the Course of action (Theureau, 2006). The course of life of the participants in the study (4 teachers and 4 students) was rebuilt thanks to the collection of experience data. The analysis and the comparison of these courses of life enabled us to highlight teachers’ and students’ (1) typical concerns, (2) a dynamics of these typical concerns during the scholar year and (3) the endorsement of typical knowledge elements. These results were enhanced by a comparative textual analysis of the teachers’ comments on the school reports from rated and non-rated assessing contexts. The results make it possible to define the appropriation process by the actors of the new assessing environment through similar kinds of activities: investigative activity, transformative activity and the quest for efficiency activity. On this basis, the outlines of an enactive conception of the academic assessment can be considered

Full textThis thesis demonstrates that a systematic experimental approach of increasing complexity allows reassessing the meaning of the redox potential (EH), and provides an update on the interpretation of its value in complex assemblages of mineral matrices, microbial consortiums, nutrients, and contaminants under dynamic, redox-oscillating conditions. To study the usefulness of EH measurements in water-saturated environmental systems a full redox cascade from +500 to -350 mV (pH ∼7.4) was reproduced in the laboratory. The experiments revealed that conventional Pt redox electrode responds to physical, chemical, and microbial processes to a different extent depending on oxygenation and on the presence of a redox buffer. The measurements of EH in argillaceous matrices depleted in the redox buffer, such as the electroactive Fe3+/Fe2+ couple, thus, are shown to have limited usefulness. In such environments, the abundant redox-sensitive couples, yet non-electroactive, such as O2/H2O, CrO42-/Cr(OH)3, NO3-/NO2-/NH4+, Sb(OH)6-/Sb2O3, and HAsO42-/H3AsO3 do not impact measured EH. To quantify the effect of oxidizing perturbations on the mobility of oxyanions in the argillaceous matrix, I performed batch experiments under controlled redox oscillations. Successive cycles of oxic and anoxic conditions were imposed on the argillaceous suspensions amended with a mixture of oxidized As(V), Sb(V), Cr(VI), and N(V). Oxyanion mobility was investigated under sterile conditions, with the addition of labile organic carbon (ethanol), and with the addition of soil microbial inoculum. Speciation analyses revealed irreversible reduction reactions with and without ethanol additions. Freshly reduced As(III), Sb(III), Cr(III), and N(III) were not re-oxidized during subsequent oxic periods demonstrating non-oscillating behavior. Microbially induced reduction transformations decreased aqueous concentrations of Sb and Cr via precipitation, removed N via volatilization, while preserved As in the solution. Depending on microbial diversity, altered by the addition of soil inoculum, two types of contaminant interplays are characterized as inhibitory and non-inhibitory reductions. These data, the representative of saturated subsurface environment (subsoil > 20 m), is further compared to oxyanion mobility in the near-surface environment (topsoil < 0.15 m). The key differences between the topsoil and subsoil systems are in the fraction of oxyhydroxide Fe-, Mn-, and Al- minerals, microbial diversity, pCO2, and the range of EH values developed during redox cycles. For example, the EH range over 900 mV (from +500 to -300 mV) in the topsoil suspension is contrasted to the EH range of 100 mV (from +350 to +250 mV) in the subsoil suspension. Furthermore, in the topsoil suspension, strong redox cycling of Fe and Mn is coincident with the oscillating mobility of As and Sb. This correlation suggests the crucial role of oxyhydroxide minerals acting not only as major sorbents, but also as catalysts for oxidation reactions eventually controlling the reversibility of contaminant sequestration. Therefore, depleted in oxyhydroxide minerals, argillaceous matrix is shown to be suitable environment for contaminant retention, as it can stand periodical redox oscillations without releasing contaminants back to the aqueous phase on the experimental time scale

Full textPeople living with HIV (PLHIV) have to take antiretroviral treatment (ART) for the rest of their lives to control the viral load and prevent HIV transmission. While many interventions have targeted PLHIV’s individual behaviour in taking their ART, very few have focused on the professional practice of nurses, even though they are key actors in the healthcare provided to PLHIV. Nurses have a social and professional responsibility to respect continuing education standards, to refresh their skills, and to acquire new ones so as to provide their clients with safe, quality care. Technology is a promising avenue for digital training and delivery of care. Two systematic reviews of systematic reviews were conducted to examine the effects of information and communication technologies as well as e-learning on nursing care. This doctoral project has two general goals: 1) Develop a virtual simulation; 2) Quantitatively and qualitatively assess the simulation’s acceptability to nurses. Two objectives were achieved to reach the first goal (simulation development): 1.1) Explore nursing practice to help PLHIV adhere to ART, and the challenges faced by nurses; and 1.2) Describe the simulation codevelopment process and the lessons learned. The second goal (simulation assessment) was met by pursuing the following three objectives: 2.1) Measure the nurses’ perceptions of the simulation’s design elements, its overall quality and technology acceptance, the simulation’s role in supporting the professional practice, and the achievement of the learning objectives; 2.2) Explore nurses’ learning experience; and 2.3) Understand how the digital simulation can contribute to nurses’ uptake of relational skills, learning progress, and transfer into practice. A qualitative study was performed to explore the nursing practice and its challenges. Among the challenges identified, one was salient: the lack of resources to help patients whose treatment-taking was suboptimal. This challenge was turned into a learning opportunity in a clinical scenario simulating a virtual patient having difficulty taking their ART. A collaborative approach helped codevelop this virtual simulation, informed by motivational interviewing. A nurse-patient consultation with preprogrammed communication schemes was scripted to encourage the nurses to apply relational skills with the virtual patient. The active learning is supported by quizzes and feedback that help nurses learn from their mistakes. A convergent mixed methods study was conducted to evaluate the simulation. A pre-experimental study with a one-group post-test design was used to describe 27 nurses’ perceptions of the simulation through an online questionnaire (80 items). Five of the 27 nurses participated in the qualitative component, sharing their learning experience in an online focus group. A narrative approach facilitated the integration of the quantitative and qualitative findings to better understand what contributed to learning progression. The nurses favourably assessed the simulation’s acceptability, including its overall quality, technology acceptance, and role in supporting practice. They stated that the simulation made them reflect about their practice as a whole, and helped improve their communication skills and the quality of the therapeutic relationship. Four themes illustrate the learning experience: 1) Motivations to engage in the simulation-based research; 2) Learning in a realistic, immersive, and non-judgmental environment; 3) Perceived utility of the simulation regarding knowledge, reflection, and relational skills (importance of communicating, listening, being present); and, 4) Perceived difficulty in engaging in the simulation-based research. The mixed methods study’s interpretative findings are as follows: 1) Influence of the simulation’s fidelity on nurses’ impression of getting real practice and of having an immersive learning experience; 2) Simulation’s perceived flexibility, efficacy, and control over one’s learning led to a positive learning experience; 3) Self-awareness and reflection in relational practice; and 4) Consolidation of the knowledge acquired and greater confidence in their abilities.

Full textWhat does it imply to govern through the concept of sustainable development the sitting of polluting industries in developing countries? To answer this question, the thesis traces, in an STS approach, a history of the govemment of the globalization of the paper industry since the 1980s. The inquiry focuses on the instruments to achieve the promise of sustainable development, including environmental impact assessment and the best available techniques. Building on the narrative as a methodology adapted to the analysis of collective action, the thesis follows the trajectories of the controversies about manufacturing technologies of pulp and their impacts on the environment, from their origins in Europe and the United States to the banks of the River Uruguay. The case of pulp mills on the River Uruguay in the 2000s offers the opportunity to study the confiieting confluence of larger trajectories: the globalization of the paper industry, the forestry development in Uruguay, the conflict between Uruguay and Argentina around the good government of the River Uruguay and the approach of the International Court of Justice to the resolution of environmental disputes. Thus, starting from this récent case of a rare richness, the thesis offers an original analysis, focused on the structural constraints, of struggles that unfold in a large number of local, national, international and transnational arenas around controversial projects and in the light of that empty political signifier they seek substantiate : sustainable development

Full textBenthic macroinvertebrates have always been recognized as better tools for bio-assessment of the ecological quality of streams in both tropical and temperate areas. The main objective of this work was to evaluate the water quality of the Western region of Cameroon most degraded by various and multiple anthropogenic activities. From these communities of macroinvertebrates benthic and their ecological preferences at the mesohabitat scale, we resulted to the construction of a bio-assessment index of the ecological quality of streams adapted to this region. From multivariate analyzes, a stream biotypology into the sampled sites, allowed us to identify different distribution patterns, with on the one hand reference sites or non-impacted and the other hand, impacted sites based on the level of urbanization and the nature of the effluents in the different sub-watersheds. A multimetric index of biological quality (MMIWC), measuring the deviation from the reference, could be created, thanks to these two groups of stations. Among the 18 candidate metrics (transformed into Ecological Quality Ratio), we selected metrics with high discrimination efficiency and a low coefficient of variation in the reference conditions. The best performing index include two metrics derived to the taxonomic diversity (Shannon index) and taxonomic composition (1-GOLD). From a test dataset different to learning dataset, we were able to verify that MMIWC was stable in the reference conditions and sensitive to the full range of anthropogenic pressures present in this region, thus confirming its generalist character

Full textThe objective of this study was to evaluate water quality of the lower Litani River and assess its feasibility for multi-purpose usage as one of the solutions to the aggravated water problems in Lebanon, To identify possible sources of metals (i.e. geological and/or anthropogenic) and then to characterize the chemical behavior of these metals in water and bed sediments, water and bed load sediments were sampled at six representatives sites which are investigated over three seasons of the year 2011-2012 (i.e. rainy, mid-rainy and dry seasons), The PCA (principal component analysis) method was used to interpret the elemental concentrations in the river water. Results show that among 18 variables, which were evaluated to characterize their physic-chemistry and metals, there are only 4 (Fe, NO2-, CaCO3, Cu) that were determined the type of environmental studied; Three groups were identified and differentiated by PCA according to the seasons. The first group includes all statements made in the mid rainy season and has a dialogue rich in Fe and NO2, and low in NH4 and EC. The second group formed in dry season, and surveys show physicochemical characteristics opposite to those in the first group, the third group formed in mid rainy, and showed the low concentration of K+, PO43- and Cl-. Sediments were characterized by a set of cations exchange capacity, granulometric, diffraction (XRD) and Fourier transformed infrared spectroscopy (FTIR( The FTIR analysis shows that the amount of montomorillonite is less than kaolinite and very much less than quartz and calcite. Pearson’s correlation was also performed in this study to compare to and determine the correlation between heavy metals in the sediments. Geo-accumulation (Igeo) index, Contamination Factor (Cf), and contamination degree (Cd) were also applying to assess the level of contamination in the sites. The results shows that the concentration of Pb, Fe are high in the site S5, S6 and the value of Cr ,Ni, are high in the S6, this results suggest that special attention must be given to the issue of element re-mobilization, because a large portion of elements in sediments are likely to release back into the water column. All the sites are characterized by moderate to highly microbial polluted range. The degree of contamination was increased in dry season. However, no critical physicochemical pollution has been reported in this part of the river; except the high concentration of Fe and NO2- in all investigated sites due to the reject of wastewater and to the distribution of touristic activities in the LLRB, the Concentrations of seven heavy metals is high(Cu, Fe, Cd , Mn , Cr, Zn, Ni and Pb) for sediment is higher according to Consensus-based sediment quality guidelines of Wisconsin (Wisconsin Department of Natural Resources, 2003) were applied to assess metal contamination in sediment

Full textDriving accidents are the leading cause of death in young people. One of the entry points to help reduce this phenomenon is to take an interest in the development of driving competence in trainees during an initial training course. This thesis proposes an original theoretical and methodological approach to apprehend the development of several dimensions of competence in trainees, based on contributions from ergonomic psychology and social psychology. Two developmental studies are carried out. The first is a transverse study based on a questionnaire used with 150 trainees. It aims to account for the development of efficacy beliefs in trainees, by comparing the assessment of their driving ability by the trainees themselves, and by trainers, at several stages of an initial training course in driving. The second is a more qualitative longitudinal study. It involved filming four “trainer-trainee” dyads, each of them five times between the beginning and the end of the driving course. It was expected that trainees’ self-efficacy beliefs would become increasingly positive, but that the trainees would not overestimate their driving ability at the end of training. These beliefs would develop jointly with other dimensions of trainee competence during the course. By the end of the course, trainees would still not be self-sufficient. It was expected that their driving activity would still be disorganized in the main training situations. We discuss these results with respect to the literature. In conclusion, we propose some lines of thinking to improve the tools used by trainers

Full textThe experimental studies conducted in the LOMC on the manufacturing of composite materials by use of the RTM (Resin Transfer Molding) process, show the appearance of bubbles at different scales, during the diffusion of the resin into the fiber matrix. They move during the process, a few are absorbed; others persist and alter the overall quality of the finished product. The subject of this thesis is to study the appearance of bubbles along fibers enclosed in a production channel. The liquid front is followed as it moves by ultrasound techniques. The appearance and the evolution of the bubbles are related, through these measures, to the processes that generate them in order to try and find improvements to the fabrication techniques. The bubbles are detected by signals processing and their evolution is followed in the flow path of the resin. Three main parts are discussed in this thesis: in the first part the behavior of ultrasonic waves interacting with the resin during polymerization is studied. The conditions for bubbles detection within the resin, by use of a phased array transducer, are discussed in the second part. The last part presents the monitoring of the evolution of the bubbles in the composite material during the manufacturing process was also performed. The aim is to quantify the concentration of bubbles relative to the rate amount of fiber and resin. In perspective, imaging techniques using the Doppler effect or nonlinear ultrasonic properties could be considered. The development of control techniques of NDT (Nondestructive Evaluation) during the production of composite materials is to should lead to a better understanding of the phenomena and to complete the feeding of the databases used in numerical simulations

Full textCaspase-2 (CASP-2) is unique among Caspases since its involved in a plethora of physiological processes and in severe and chronic neurodegenerative processes. In this context, recent studies have indicated that CASP-2 is a potential therapeutic target for Alzheimer’s disease. It is therefore necessary to develop specific inhibitors which would constitute pharmacological tools to better understand the role of this protease in the physiology and pathology of the neuron. The current Caspases inhibitors are mostly tetra or pentapeptide sequences that reproduce the patterns preferentially recognized by these enzymes. During this thesis project, we used three identification strategies ; (i) a rational design approach of peptides targeting the active site, (ii) in silico design of peptides of the dimerization interface, (iii) rational an random screening of small organic molecules. Among these strategies, inhibition of the active site has been shown to be the most productive one. We have been able to demonstrate that the variation of the Alanine residue in P2 on the pattern VDVAD increased efficiency and selectivity parameters. Based on this observation, a serie of peptides “LJ” with various inhibitory mechanisms has been developed. Two compounds LJ2 and LJ3, demonstrated excellent inactivation and selectivity parameters toward CASP-2. In neuronal networks reconstructed in vitro, LJ2 and LJ3 protect against synapse loss. This thesis project opens the field to new perspectives on the functional level as well as on the therapeutic plan

Full textLebanon has abundant water, but its river is polluted. The Litani River is the largest one, draining from north to south in the central core of the country (Bekaa Valley) before turning west to the sea. It crosses down a rather deep valley and passes by several urban agglomerations and industrial zones, which use its water as a discharge system of their waste. This study shows the impact of the anthropic activities on the water quality of this river. Physical (pH, T°, TDS, Ec), chemical (Na+, Ca2+, Mg2+, Cl?, SO2?4, NH3+, NO?3, PO2?4, K+, BOD5 and COD), heavy metals (Fe, Ni, Zn, Cu, Cr, Al, Ba, Pb, Mn) and microbiological parameters of water quality assessment and sediment for the Upper Litani River Basin was performed. They were investigated during three seasons of rainy, mid-rainy spring and wet season, during the years 2010-2013 to determine correlation between chosen chemical water parameters and bottom sediments parameters. Microbiological and physico-chemical analyses are performed in accordance International methods (e.g. European Standard Methods, WHO). In addition, Multivariate statistical methods (Hierarchical Clustering Analysis: HCA, and Principal Component Analysis: PCA) and Pearson’s correlation were applied to figure out the influence of pollutants disposal in the Lake and the River as well. Sediments were characterized by a set of chemical analyses, cations exchange capacity, mineralogical X-ray diffraction (XRD), Fourier transformed infrared spectroscopy (FTIR). To assess metal contamination in sediments, Consensus-Based Sediment Quality Guidelines of Wisconsin (CBSQG) were applied. The metals contamination in the sediments was also evaluated by contamination factor (Cf), and the results showed that the effect of seasonal variations was important in the Upper Litani River Basin and the degree of contamination was increased in dry season. All the sites are characterized by moderate to highly microbial polluted range and some site was highly polluted and contaminated

Full textAgainst the backdrop of population ageing and medical progress, the prevalence of long-term disorders is rising worldwide. As a consequence, an increasing number of patients need to take medications daily. Medication adherence, which can be defined as the extent to which patients’ medication-taking behaviors coincides with medical prescriptions, may become ever harder to achieve. Non-adherence is a main challenge for physicians and for researchers, especially given its complexity and its dynamic evolution over time. First, we developed a new instrument to assess medication adherence to each individual medication taken by patients undergoing long-term treatment, taking into account different types of medication-taking behavior. We assessed the instrument’s validity and reliability among 243 outpatients and inpatients taking 961 medications, in France. Second, we focused on the discordance between medication adherence as reported by patients and drug importance as reported by their physicians. We compared the opinions of 128 patients and physicians and showed that some drugs considered important by the physicians were not correctly taken by patients, a situation that may lead to potential severe consequences. On the contrary, some drugs considered less important by physicians were correctly taken by physicians, which may lead to potential overprescription and avoidable burden of treatment. Third, we used a crowd sourcing approach to assess physicians’ estimation of the threshold for unacceptable risk of non-adherence, for two distinct types of behavior (episodic missing doses and drug holidays) for the most prescribed drugs in France. Physicians’ estimations varied considerably according to the drugs assessed, suggesting that according to physicians, some drugs are “more forgiving” than others. Our findings confirm that medication adherence is a complex phenomenon that should not be simply dichotomized into « good adherence » and « bad adherence ». Future work will consist in developing and validating a new online tool inspired from our first study. We will try to sharpen our understanding of the results in our third study by comparing physicians’ estimations to patients’ adherence data. Future interventions are still needed to improve patient-physician discussion about medications in order to reach an “optimal adherence” rather than a "perfect adherence", taking into account patients’ perspectives

We first evaluated the predictive value of susceptibility vessel sign (SVS) on T2* MRI sequence after intravenous thrombolysis and studied course of SVS using sequential MRI assessment. We confirm that SVS is a strong predictor of no recanalisation, and underline discrepancies between MR angiography and T2* data. In the second part, we assessed the usefulness of near-infrared spectroscopy (NIRS) to monitor recanalisation during mechanical thrombectomy. NIRS is a reliable tool, but still suffer of challenging limitations

A device delivers nasal airflow at a sufficient pressure level to prevent UA collapse during sleep. New technologies provides this treatment with an auto adjusted pressure to adapt to patient needs. The principles of these devices is based on two steps. An event detection step and a reaction one. We developed a bench test for such devices. It includes a Starling resistor to take into account the UA resistance and a flow generator. Thus, it can simulate different events as those observed on patients. This bench test allow to evaluate differnet algorithms before clinical studies
