Повний текст джерелаComposé principalement de monoxyde de carbone (CO) et d'hydrogène (H2), le gaz de synthèse est un vecteur énergétique polyvalent, qui peut être converti en un combustible liquide ou gazeux ou peut servir à la production d'électricité. La capacité du CO ou de gaz de synthèse à servir comme unique donneur d'électrons dans la production d'électricité dans une pile à combustible microbienne (PCM) ayant été récemment démontrée, la présente étude visa l'obtention d'un gain d'éfficacité de production, avec soit du CO ou du gaz de synthèse comme combustible, grâce à un aménagement amélioré de la PCM. L'étude visa aussi à élucider les communautés microbiennes et voies de biotransformation liées à la production d'électricité à partir de CO ou de gaz de synthèse dans une PCM.Un des principaux défis à une hausse d'efficacité de bioconversion de CO ou de gaz de synthèse est la faible solubilité en phase aqueuse de ces substrats gazeux. Le premier volet de ce travail démontra l'applicabilité de systèmes à membrane de silicone pour réaliser un transfert accru de CO vers l'anode liquide du PCM. L'intégration d'une membrane plane en silicone ou de tube en silicone à parois minces dans la chambre anodique d'une PCM alimentée en CO, a permis d'atteindre une éfficacité de transformation de CO accrue, et par conséquente une performance améliorée de la PCM. Une efficacité de transformation de CO de 77% et une puissance maximale de 18 mW/L furent obtenues pour une PCM équipée d'une membrane en silicone. Une efficacité de transformation de CO comparativement plus élevée (98%) fut obtenue pour une PCM équipée de tube en silicone à parois minces, mais la concentration éleve de CO dissoute dans le liquide anodique enraya en partie l'activité microbienne, baissant ainsi la puissance maximale à 13 mW/L . Un transfer gazeux efficace permetta de mettre l'accent sur le processus microbiologique. En un second volet, les communautés microbiennes et voies de biotransformation prévalentes dans deux PCM mésophiliques alimentées en CO furent élucidés. L'identification de microorganismes appartenants aux genres Geobacter, Desulfovibrio, et Clostridium, ainsi que la détection d'acétate comme principal produit métabolique dans les deux PCM, confirma notre hypothèse que la production d'électricité à partir de CO ou de gaz de synthèse dans une PCM mésophilique s'opère principalement en deux étapes: (i) le CO ou gaz de synthèse est premièrement converti en acétate par des carboxydobactéries et bactéries homoacétogéniques, puis (ii) l'acétate est oxydé par des microorganismes électrigènes tolérants au CO. Le gaz de synthèse étant principalement un gaz chaud, la bioconversion de CO ou de gaz de synthèse dans une PCM fut évalue sous des condition thermophiles à 50°C. Une puissance volumétrique accrue (33-35 mW/L) et une éfficacité de conversion de gaz de synthèse de 87-98% furent atteintes. De plus une efficacité coulombienne (EC) de 26% fut atteinte. Dans le dernier volet de cette étude, la faisabilité d'une configuration à multiples électrodes visant à permettre des PCMs consommant du gaz de synthèse à obtenir une puissance volumétrique et une EC accrue, fut évaluée à des températures de 37°C à 50°C. L'influence de la position dans laquelle les anodes et cathodes furent disposées sur la puissance générée fut évalue. Une densité de puissance maximale de 33 mW/L et une CE de 43 % furent atteintes à une température de fonctionnement de 37 °C. La densité de puissance d'une PCM fut largement influencée par la disposition et le nombre des anodes de cathodes. Un arrangement trois anodes-deux cathodes (3A-2C) offrant la plus grande puissance.

Повний текст джерелаMultiple sclerosis (MS) is a neuro-inflammatory disease of the central nervous system (CNS). Causes are multifactorial enrolling both genetic predisposition and influence of environmental factors. In 85% of cases, patients experience relapse corresponding to the occurrence of neurologic signs, followed by a phase of partial or total remission. Several studies put forth the hypothesis that relapses rate varies across season, mainly occurring during spring and summer. This temporal fluctuation raised the question of season-dependent parameters influence such as sunlight exposure and vitamin D, melatonin level or ambient air pollution. Considering this variation of air pollution, we explored the short-term impact of fine particles (PM10), benzene (C6H6), nitrogen dioxide (NO2), carbon monoxide (CO) and ground-level ozone (O3), on the risk of relapse triggering, separately for "cold" (i.e., October-March) and "hot" (April-September) season. This work has drawn from data of patients provided by the alSacEP network. We included 424 patients affected with remitting MS onset who experienced 1,783 relapses over the 2000-2009 period. Daily level of air pollution was modeled through ADMS-Urban software at the census block scale of the Strasbourg metropolitan area (AASQA ATMO Grand Est). Furthermore, an individual survey was conducted among all the patients (PT) in order to collect individual socioeconomic (SES) and lifestyle features. Finally, the census block SES position was estimated using a composite deprivation index - created from the INSEE census data. A short-term (3 days preceding the relapse) seasonal adverse effect was observed in PT, in particular during exposure to O3 in "hot" season and PM10 and NO2 in "cold" season. Results also suggest that the SES context might exacerbate these associations, in particular among patients who were living in deprived neighborhood with exposure to PM10, NO2, C6H6 and CO ("cold) and those who were living in most well-of and deprived places with exposure to O3 ("hot"). Finally, we observed among Ps that low education level, average family income, smoking and lack of physical activity are more associated with the risk of relapse triggering when patients were exposed to air pollution. This work shows the need to investigate environmental exposure such as air pollution along the SEP course using a holistic approach integrating individual and contextual factors

Повний текст джерелаSouth Durban is in the province of Kwazulu-Natal in South Africa and is home to two international petro-chemical refineries, a paper mill, sewage works, an international airport, a chemical tank farm with approximately 970 tanks, a number of landfill sites, an airport, various processing and manufacturing industries which are all in close proximity to residential and recreational areas. This area is known as the South Durban Industrial Basin (SDIB). Serious concerns have arisen about the potential health impacts that could arise from ambient air pollution from these industries. Learners and staff at the Settlers Primary School situated in Merebank, a suburb in the SDIB, perceived themselves to be at risk for air pollutant related health effects owing to the schools’ geographic location. The aims of this study was a) to determine the prevalence of asthma among learners from Grades 3 and 6 and staff at Settlers Primary School and b) To investigate whether outdoor air pollutant concentrations of sulphur dioxide (SO2), oxides of nitrogen (NOx), ozone (O3), total reduced sulphur (TRS), carbon monoxide (CO) and respirable particulate matter less than 10 microns (PM10) were associated with increased signs and symptoms of asthma in the study population.

Повний текст джерелаThe Infrared Atmospheric Sounding Interferometer (lASI), operational in polar-orbit since 2006 on the European MetOp-A satellite, is the most advanced of its kind in space. It has been designed to provide soundings of the troposphere and lower stratosphere at nadir in a spectral interval of 0.25 em" across the range 645-2 760 em". Fine spectral sampling such as this is imperative in the sounding of trace gases. Since its launch, the routine retrievals of greenhouse, species from IASI measurements have made a valuable contribution to atmospheric chemistry studies at a global scale. The main contribution of this thesis is the development of a new trace gas retrieval scheme for IASI measurements. The goal was to improve on the global operational scheme in terms of the algorithm complexity, speed of calculation and spatial resolution achieved in the final solution. This schemedirectly retrieves column integrated trace gas densities at single field-of-view (FOV) from IASI measurements within a 10% accuracy limit. The scheme is built on the Bayesian framework of probability and based on the assumption that the inversion of total column values, as apposed to gas profiles, is a near-linear problem. Performance of the retrieval scheme is demonstrated on simulated noisy measurements for carbon monoxide (CO). Being a linear solution, the scheme is'highly dependent on the accuracy of the a priori. A statistical estimate of the a priori was computed using a principal component regression analysis with 50 eigenvectors. The corresponding root-mean-square (RMS) error of the a priori was calculated to be 9.3%. In general terms, the physical retrieval improved on the a priori, and sensitivity studies were performed to demonstrate the accuracy and stability of the retrieval scheme under a numberof perturbations. A full system characterization and error analysis is additionally preformed to elicidate the nature of this complex problem. The hyperspectral IASI measurements introduce a significant correlation error in the retrieval. The Absorption Line Cluster (ALC) channel selection method was developed in this thesis, to address the correlation error explicitly. When a first neighbour correlation factor of 0.71 is assumed in the measurement error covariance for the clusters of ALC channels, then most of the correlation error is removed in the retrieval. In conclusion, the total column trace gas retrieval scheme developed here is fast, simple, intuitive, transparent and robust. These characteristics together make it highly suitable for implementation in an operational environment intended for air quality monitoring on a regional scale.
