Les cyanobactéries (ou algues bleues) sont des organismes procaryotes photosynthétiques considérés comme les ancêtres des plastes des végétaux eucaryotes. Présentes dans différents types d’habitats terrestres ou aquatiques, elles peuvent produire des composés bioactifs d’intérêt pour des industries pharmaceutiques, ou encore des toxines présentant un risque potentiel pour la santé humaine et animale. Il est donc important de pouvoir caractériser différentes espèces et différents génotypes de ces organismes de manière indubitable pour pouvoir détecter leur présence/absence, évaluer leur rôle au sein de leur écosystème, ainsi que l’influence des facteurs environnementaux sur leur cycle de vie. La caractérisation taxonomique des cyanobactéries a longtemps été réalisée par l’étude des critères morphologiques. Cependant cette approche s’avère délicate quand ces critères peuvent être altérés par la mise en culture. De plus, cette approche requiert une expérience importante et ne permet pas de différencier des génotypes toxiques. La séquence du gène codant pour l’ARN ribosomique 16S est utilisée pour différencier les cyanobactéries jusqu’au genre et parfois jusqu’à l’espèce. Mais, dans certains cas, elle ne coïncide ni avec la description morphologique spécifique, ni avec la production de certaines toxines. Dans le cadre de cette étude, nous proposons d’évaluer l’information taxonomique et génotypique de marqueurs génétiques singuliers présents dans les génomes de cyanobactéries séquencés d la base de données Genbank. Les distances génétiques entre les parties de 32 génomes suffisamment conservées pour être alignées ont été mesurées. Ces distances ont ensuite été comparées par régression linéaire aux distances génétiques de différents loci précis (ARNr 16S, kaiC, lexA, rpoC1, recA). Les résultats préliminaires montrent un R2 de 0,9141 pour la régression linéaire entre les distances génétiques du gène recA et des régions conservées des génomes séquencés appartenant au genre Prochlorococcus. Ce résultat suggère que recA serait potentiellement un bon marqueur pour génotyper des organismes du genre Prochlorococcus. [less ▲]

This paper presents a cogeneration system composed of a biomass-fuelled boiler and of an Organic Rankine Cycle (ORC). The first part of the paper describes the model of the system. This model is built by interconnecting the sub-models of the different components: heat exchangers, pump, boiler and scroll expander. In the second part, the results of an experimental study are presented : this study aimed at evaluating the performances of an ORC working with refrigerant R-123 and using scroll expander. The above models are validated using test results. The last part of the paper investigates, through simulations, the performances of the cogeneration system and points out some possible improvements.

This paper relates to the development of a new concept of 220.000 m³ LNG designed by AKERYARDS France. This work is performed in the framework of FP6 IMPROVE project. The first phase of the activity related to the identification of stakeholder’s requirements and the definition of key performance indicators. In parallel, several calculations have been performed to test the existing tools and to evaluate the potential gain at the concept design. These activities, associated with the definition of a 220000 m³ QuatarFlex prototype, including the aspects related to the naval architecture and general arrangement, have been re-grouped in the so-called “first design loop”. The second phase concerns the development of new modules to be integrated in the optimization tools in order to satisfy the requirements defined in the first phase. The final phase will be the application of the new (improved) optimization tools for the final LNG product. We highlight that the main target will be the multi-objective structural optimization of the prototype defined by “the first design loop”. However, some feed-back concerning the naval architecture point of view could be expected in this phase. The aim of the paper is to present the results of the first phase, as well as an overview of the analyses carried out during the “first design loop”. Details about the different methodologies proposed for the second phase of the development are given. [less ▲]

The major sources of fluorine in the stratosphere are CFC-11 and CFC-12. During the decomposition process, fluorine is first present in the form of carbonyl compounds (e.g. carbonyl fluoride (COF2)). Given its long life time, COF2 is the second most abundant stratospheric fluorine reservoir. Earliest, COF2 vertical distributions were derived from occultation measurements performed by the ATMOS instrument during the SPACELAB-3 Space Shuttle mission in 1985. The Canadian FTIR spectrometer ACE-FTS, onboard the SCISAT-1 satellite, is the first instrument since the last ATMOS flight in 1994, to record COF2 vertical profiles from space. Four years of ACE-FTS occultation measurements are presently available. Several COF2 IR absorption lines located either in the so-called InSb (1-5 µm) and MCT (2-16 µm) spectral ranges can be used to determine its total column from ground-based high-resolution FTIR observations. In addition, we have proposed, during the EGU General Assembly 2007, an original retrieval procedure that allows us to derive information on the COF2 vertical distribution, between 17 and 30 km, from ground-based FTIR spectra recorded at Jungfraujoch. This “multi-microwindows multi-spectra” approach, using the SFIT-2 v3.91 algorithm, has been completely characterized in terms of fitting strategy and information content. Some examples of COF2 vertical profiles inversions were also presented. This year, we will complete the characterization of the multi-microwindows multi-spectra fitting procedure by exposing the full error budget affecting our COF2 partial and total columns products. Also, comparisons with COF2 model runs generated by the 3D CTM KASIMA (KArlsruhe SImulation model of the Middle Atmosphere) will be presented and critically discussed. [less ▲]

The purpose of this study is to identify the dimensions of beliefs among students choosing a university town and investigate if brand concept mapping (BCM) is applicable to cities. The city brand image is captured through Zaltman’s Metaphor Elicitation Technique (ZMET), BCM and importance-performance ratings. The authors identified six categories of criteria used by students when selecting a university town. In applying the results to Liege, a Belgian university town, the authors showed that Liege is recognized for its nightlife, its young population and its historical heritage. This paper proposes a useful framework for city councils to assess how to compare the perception of different segments regarding cities; how to improve the city brand image; how to compare different university towns and how to attract students. Finally, the research validates earlier studies on BCM, confirms the improvement of the methodology and widens its applications to city brands. [less ▲]

Survival from Schistosoma mansoni infection requires the development of a finely regulated TH2-polarized immune response driven by the parasite egg antigens. A number of studies have proposed that S. mansoni egg antigens induce peripheral FoxP3-expressing regulatory T cells involved in the modulation of pro-inflammatory T helper immune responses (1-3). However, the tight regulation between antagonistic TH1, TH2 and Treg developmental programs in response to S. mansoni egg-antigens remains poorly understood. In this study, we demonstrated in vitro that IL-4 strongly inhibits TGF1-induced FoxP3 expression by naive T cells and this inhibition is dependent on IL-4R expression on T cells. Surprisingly, wild-type mice that developed a strong TH2 immune response to S. mansoni egg antigens were able to modulate the magnitude of egg-induced inflammation in contrast to mice disrupted of IL-4R globally or specifically on T cells. The TH2 response developed by wild-type mice also prevented the induction of FoxP3-expressing CD4+ T cells in the draining lymph node. This was not apparent in LckcreIL-4R-/lox or IL-4R-/- mice. In addition, IL-4 neutralization in vivo promoted the induction of FoxP3+CD4+ cells in the draining lymph node. Finally, IL-4 responsiveness by T cells induced a CD103-expressing CD4+ T cell population which produced IL-10 in response to egg antigens. Consequently, our study shows that the modulation of egg-induced inflammation is independent of FoxP3-expressing regulatory T cells but highlights a potential role of CD103-expressing CD4+ T cells as IL-10 producing regulatory T cells.

Hybrid Hydraulic Vehicle (HHV) technology is an alternative solution to classical Hybrid Electric Vehicles (HEV). The authors’s previous studies of hybrid hydraulic systems clearly demonstrated that HHV can lead to fuel savings even though smaller than HEV. Hydraulic energy recovery systems are well adapted for heavy urban vehicles with frequent starts and stops because the weight penalty of the hydraulic system can be mitigated while taking benefit of their high specific power property for power assist. This recent work investigates and compares, from an economical and technical point of view, both HHV and HEV buses using batteries or super capacitors as energy storage systems. The fuel consumption of different hybrid busses is simulated using ADVISOR on the basis of three European SORT driving cycles. The results show that HHV and HEV with super capacitors can not rival from the consumption point of view with the HEV using batteries as energy storage system. But they can be economically interesting because of their lower cost and the longer service life of their energy storage system. [less ▲]

The sighting frequency (SF), site fidelity, home-range and group composition of bottlenose dolphins (Tursiops truncatus) were assessed during a photo-identification study in 2006-2007. This study aims to provide first data on this unknown austral bottlenose dolphin population to answer to their increasing conservation needs. Data and pictures were collected during 132 surveys with an average observation effort of 2.8h (SD=1.6) per survey. All clear pictures were analysed using the automatic identification systems FinEx and FinMatch (EuroPhlukes Initiative). The SF was obtained dividing the number of sightings by the amount of effort. Site-fidelity was estimated using the Capture Mark Recapture method and the degree of residency by the re-identification frequency following Culloch (2004). In total, 377.4h were spent searching for bottlenose dolphins of which 57.3h were spent in the presence of 126 dolphin groups divided in 105 sightings. The SF was 0.28/h with and average duration of 43.2min/sighting (SD=0.76). A total of 43 dolphins were classified into an identification catalogue. These recognizable dolphins were re-identified up to 10 days with 44% (n=43) showing a degree of residency (resighting frequency (RF)¿4). The average group size was 6.1 (SD=7.9) ranging from one to fifty animals. Group size increased significantly with the presence of calves and with the distance from the coast. Nevertheless, all dolphins were seen in inshore waters ¿20m deep. The most frequent group formation was loose (34.5%), variable (29.8%), disperse (20.2%) and tight (15.5%). At least 6 identified dolphins, including one mother with her calf, were photographed in the mouth of the Rio Negro 250km from the study area indicating that their home-range is far from limited to Bahia de San Antonio. Data indicate that it concerns a resident but yet unknown population of bottlenose dolphins with a high commercial potential and an urgent need of conservation measurements. [less ▲]

It should allow us to describe located dialectal forms and progressively define groups of them, according to the way they resemble each other (e. g., from an etymological, morphological or phonetic point of view). The software-assisted process would then conform to methodological requirements of traditional scientific work, as it has thus far.

Appartenant à la famille des Caliciviridae, les norovirus sont des virus non enveloppés. Leur génome est composé d’un ARN monocaténaire de polarité positive d’approximativement 7,5 kb. Trois cadres ouverts de lecture (ORFs) y sont décrits et l’ORF 2 code pour l’unique protéine composant leur capside. Les norovirus infectent l’homme et les animaux (bovins, porcins, murins). Chez l’homme, ils sont des agents majeurs de gastroentérite sporadique ou épidémique d’origine souvent alimentaire. Chez le bovin, ils seraient également les agents d’entérite bénigne bien qu’à l’heure actuelle aucune épidémie à norovirus n’ait été décrite chez cette espèce. La voie d’infection des norovirus est habituellement oro-fécale, ils sont très résistants dans l’environnement et une infection peut survenir même avec une très faible dose infectieuse. Les norovirus humains et animaux sont relativement proches génétiquement et coexistent parfois de manière très étroite dans nos pays d’Europe du nord. Il est donc logique d’envisager le risque zoonotique lié aux norovirus animaux et plus particulièrement celui lié aux norovirus bovins. Ces derniers sont considérés comme endémiques dans des pays proches de la Belgique et une forte séroprévalence apparente a été montrée dans ce pays. Ce travail avait pour but l’étude moléculaire des souches de norovirus bovins ayant circulé au cours de l’année 2007. L’investigation préliminaire de leur potentiel zoonotique a également été étudiée au travers des interactions virus-cellules. Une banque d’échantillons de matières fécales bovines en provenance d’un laboratoire d’analyse et de diagnostic vétérinaire installé en Région Wallonne (ARSIA) a été constituée tout au long de l’année. Un diagnostic rapide par RT PCR a été effectué pour détecter des séquences de norovirus bovins des deux génotypes décrits actuellement. Les couples d’amorces utilisés, JV12-13, BEC et CBECu s’hybridaient dans les régions codant pour la polymérase virale et dans le début de l’ORF2, régions assez conservées. Ces séquences ont été analysées comparativement à celles isolées dans les années précédentes. Parallèlement, des pseudoparticules d’une souche de norovirus bovin (B309) et d’une souche de norovirus humain (HV) ont été produites comme décrit précédemment avec de légères modifications. Leur concentration protéique a été obtenue par BCA et des lapins ont été immunisés avec ces antigènes. Trois injections de 25 µg d’antigènes dilués dans du PBS et complétées avec les adjuvants complet et incomplet de Freund ont été réalisées. La production d’un sérum hyperimmun dirigé contre la protéine de capside des norovirus a été contrôlée par ELISA. Les pseudoparticules ont ensuite été utilisées pour des études de liaisons sur différents types cellulaires dont les Caco2, cellules connues pour exprimer à leur surface des oligosaccharides proches de ceux des systèmes ABO et de Lewis, ces oligosaccharides étant impliqués comme récepteurs cellulaires pour de nombreux norovirus humains. L’attachement des pseudoparticules a été mis en évidence par immunofluorescence indirecte en utilisant les sérums polyclonaux et un anticorps secondaire anti-lapin couplé à l’Alexa fluor 488. Des séquences de norovirus bovins ont pu être identifiées dans les prélèvements de matières fécales bovines tout au long de la période de constitution de la banque, ces séquences étant proches de celles des norovirus bovins de génotype 2. Une prévalence apparente dans les cheptels bovins de Wallonie a put être déterminée. Au cours de premiers tests réalisés, si les pseudoparticules de HV se sont liées aux cellules Caco2, aucun attachement des pseudoparticules du norovirus bovin à ces mêmes cellules n’a pu être démontré. Nous avons donc montré que les norovirus sont largement répandus en Belgique et leur diagnostic tout au long de la période d’échantillonnage prouve un certain caractère endémique de ces virus en Belgique ; cette constatation rejoignant celles en provenance de pays proches (Grande Bretagne, Allemagne) et de séroprévalence.

The diluted combustion (called also flameless oxidation) has been already applied in furnaces technology to get high process thermal efficiency with low NOx emissions. The aim of this work is to assess the technical feasibility and highlight the specific problems of application of diluted combustion in a medium scale boiler. The main difficulty is due to the high geometrical confinement and heat losses of a typical boiler combustion chamber, which could prevent from getting the minimum level of reactants dilution and temperature needed to reach diluted combustion regime. The idea is to perform direct injection of the air and the gas in the combustion chamber in order to get a high dilution of the reactants and a mixture temperature above the auto-ignition threshold. Our test bench consists in a Viessmann hot water boiler whose nominal output power is 370 kW. The combustion chamber of this boiler is cylindrical (length = 1.41 m, diameter = 0.56 m) and is watercooled. A preliminary CFD study (Fluent ®) has first been performed to select on the market a jet burner (to be used for the preheating of the combustion chamber) and to determine the position of the air and gas injectors able to generate the requirements of diluted combustion. The selected burner has been purchased and fitted on the boiler. Then, the boiler-burner set has been characterized experimentally in normal combustion regime in order to adapt the boundary conditions to the heat balance. The temperature and the CO concentration will be measured in several locations in the combustion chamber at different firing rate and air excess. In short, the selected burner provides as expected the required preheating and the generated flame doesn’t impact the bottom of the combustion chamber. The results obtained experimentally confirm the simulation results in normal combustion regime. The last part of this work will consist in the determination of the feasibility of the diluted combustion in this boiler. [less ▲]

Les systèmes de coordonnées sont des systèmes distribués ayant pour but, à partir de mesures de distance (par exemple RTT) entre certaines paires de noeuds, d’associer des coordonnées à chaque noeud dans un espace métrique. Toutefois, de tels systèmes ne fonctionnent pas correctement lorsque les distances mesurées ne respectent pas les inégalités triangulaires. Or, les violations de ces inégalités, appelées TIV, sont fréquentes dans l’Internet. Nous proposons une étude approfondie de l’impact des TIV sur le système de coordonnées Vivaldi. Nous quantifions et expliquons les erreurs de prédiction de distance et l’instabilité des coordonnées causées par les TIV selon leur fréquence et leur sévérité. Nous montrons aussi que la distance entre deux noeuds, mesurée par le RTT, est corrélée à la probabilité d’existence d’une TIV. Enfin, nous recommandons un système de coordonnées hiérarchique, et nous montrons, par des simulations sur une matrice de délais réelle, qu’une telle approche réduit l’impact des TIV. [less ▲]

The electric vehicles (EV) and sometimes the hybrid electric vehicle (HEV) technologies are environmentally very efficient but can not succeed on the market because of a smaller ability to satisfy customer’s requirements. Comparison of clean technologies in automotive and transportation systems has been measured using different analysis tools such as LCA (life cycle analysis). However, these instruments never account for the user’s satisfaction which partly explains the market acceptance problems. The Eco efficiency is a global index which accounts for both environment impacts and user satisfaction. The main objective of vehicle powertrain hybridization is to improve the fuel consumption and environment pollutants impact (Eco-score) without decreasing the vehicle performances and other user satisfaction criteria. The objective of this study is to minimize the Eco-score indicator of HEV with respect to the user satisfaction criteria. The approach is formulated as a multidisciplinary optimization problem. At first the EV or HEV are modeled and simulated using ADVISOR (advanced vehicle simulator) with respect to several driving situations. Then emissions can be determined and the Ecoscore indicator can be calculated. User Satisfaction can be evaluated based on performance criteria extracted from ADVISOR simulation and on simple evaluation tools relying on the state-of-the art of technological information for safety, reliability and daily cost. In this study the design problem is stated as follows: select mechanical and electric components (like engine, motor and battery sizes) to minimize the Ecoscore indicator and to maximize user satisfaction criteria subject to catalogue constraints on the choice of the components. The approach is illustrated on applications dealing with parallel hybrid electric vehicles. [less ▲]
