The daily atmospheric circulation patterns classification is founded on a 100 km regular grid centred on Belgium. The geopotential heights of 500, 850 and 1000 hPa levels were extracted <br />from the ERA-40 database on the period 1958-2002 and from ECMWF operational analysis until the end of year 2007. The classification was based on a similarity index calculated on the orientation of exaggerated slopes of different daily geopotential fields. Wildfire occurrences were analyzed in April and September (which are the two months with the most frequent wildfire-days in Belgium) together with monthly frequencies and persistences of daily atmospheric circulation pattern classes as well as with yearly variability of weather climate conditions.

Results from atmosphere-ocean general circulation models (AOGCM's) for the IPCC 4th Assessment Report are used to investigate surface mass balance (SMB) future projections of the Greenland ice sheet (GrIS). The most efficient models for the GrIS climate modeling are chosen by comparison between the 1970-1999 outputs (averages and trends) from the 20C3M Experiment outputs, and the reanalyses (ECMWF, NCEP) as well as climatologies. The SMB is estimated from the summer temperature (from which is deduced the run-off) and annual snowfall from the well-adapted AOGCM's. It is validated with 1970-1999 results from the regional climate model MAR by interpolating the AOGCM's outputs on the MAR grid. However, large uncertainties remain in these SMB projections due to the simplified physic and coarse AOGCM's resolution. High resolution simulations made with the MAR model (which simulates explicitly the SMB by taking into account the surface feedbacks) forced at its boundaries by a GrIS well-adapted AOGCM could bring more precise brief replies.

In the context of an ESA-funded study on an air separation device intended to provide in-flight Oxygen Collection capability to future launchers, experimental and system level investigations are performed. The project consortium is run by the Université Libre de Bruxelles and includes the Belgian Defence, Techspace Aero (Safran Group) and Liège university among others. In-flight Oxygen Collection has already been described in previous publications, mainly as a conceptual approach. The improvement potentials have been studied and possible uses of the technology go beyond the concept presented here. That is in the aerospace field and also outside, in a much wider range of applications. Hardware work on compact separation are seldom described. As the setup was nearing completion, design know how improved. The last problems were solved and the setup was made fully operational and subject to testing. The following review summarizes the work with latest information on the technological and experimental aspects. In the vehicles using air separation and collection, the cooling capacity of the fuel, liquid hydrogen, is used during a first air breathing phase of the flight to enrich in oxygen and liquefy a fraction of the incoming air. Compact and light weight heat exchanger, coupled to the separator, perform that task. The main advantages of the concept, applied in our preferred concept to TSTO’s, are a much reduced take off mass, a reduced mass for the liquid rocket engines and a much increased operational flexibility in terms of reachable orbit and launch window. Moreover, unlike scramjet propulsion, separation does not rely on high technology material but on readily available material and hardware used with proper design know how and appropriate expertise. The experimental setup development follows a somewhat different route. Liquid and saturated gaseous air are prepared in special heat exchangers before the separator can be fed, the cold source used being liquid nitrogen. The experimental separator itself is, in reality, a 'section' of a real separator. Disposing of the fluids in this machine deserves special care, since pressure has to be controlled while a liquid seal has to be kept stable in most of the operating conditions. Some workarounds had to be developed for that last problem and different solutions were kept available during the testing. Separating is an aspect, interactively measuring -required to tune to proper performance- is another. The operating fluids, that are supposed to be liquid or gaseous in the simple modeling, are in practice often two phase, which is difficult to asses during test and which can strongly impact flow and concentration measurements. High temperature gradients, low temperatures had to be considered for mechanical, sealing and bearing design, nevertheless, strong uncertainty remained before separation results are presented and demonstrate the concept. Most result went above expectations and much further compactification potentials are present. The know how gathered from testing experience allows to foresee improvement directions, both in the global concept and the detail design of a real unit. Those results will allow to extrapolate the real potentials of the separator design developed by our laboratory to the bigger units required for a real concept. [less ▲]

Ile de La Réunion is a complementary site in the Network for the Detection of Atmospheric Composition Change (NDACC), situated in the southern tropics, at 21°S, 55°E. In support of a better understanding of atmospheric chemistry and physics above tropical regions, we have implemented new ground-based MAX-DOAS (multi-axis DOAS) and FTIR (Fourier transform infrared) observations at this site, on a campaign basis since 2002. At present, we have data from 2002 (month of October), 2004 (August to October) and 2007 (end of May until the end of October). Additional campaigns are planned until the availability of a new infrastructure for permanent observations at the Maido (~ 2000 masl), around 2010. Here, we report on the available time series for a number of tropospheric species (CO, H2CO and CH4,) and stratospheric halogen species, comparisons between MAX-DOAS and FTIR data of H2CO, and comparisons of ground-based and satellite data.

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 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 ▲]

This paper revisits the traditional return-based style analysis (RBSA) in presence of time-varying exposures and errors-in-variables (EIV). We first apply a selection algorithm using the Kalman filter to identify the more appropriate benchmarks for the analyzed fund return. Then, we compute their corresponding higher moment estimated errors-in-variables, i.e. the measurement error series introducing the (cross) moments of order three and four. We adjust the selected benchmarks by subtracting their higher moments estimated EIV from the initial return series, to obtain an estimate of the true uncontaminated benchmarks. We finally run the Kalman filter on these adjusted regressors. Analyzing EDHEC alternative indexes styles, we show that this technique improves the factor loadings and permits to identify more precisely the return sources of the considered hedge fund strategy.

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 ▲]

We investigated whether the use of perceptual fluency as recognition cue by patients with Alzheimer disease (AD) depends on whether fluency is perceived as relevant to the recognition decision. In normal subjects, enhanced perceptual fluency increased positive recognition responses when study and test stimuli were presented in the same sensory modality but not when stimuli were presented in different modalities (Westerman et al., J. of Mem. & Lang., 47, 2002). These results suggest that the use of perceptual fluency as a heuristic in recognition memory depends on the correspondence between study and test modalities and thus on the perceived usefulness of fluency. We investigated this change of sensory modality between study and test phases in 16 AD patients and 16 matched normal controls by using a verbal recognition task. The perceptual fluency of recognition test items was enhanced by briefly presenting a prime that matched the subsequent test item. We observed that changes in modality attenuated the contribution of fluency to the recognition decision in both subjects groups. In addition, we noted a positive correlation between fluency use and metamemory self-evaluation. These results suggest that the fluency heuristic is subject to metacognitive control in AD patients, exactly in the same way as normal subject, since patients’ attributions of perceptual fluency depend on expectations about relevance of fluency as memory cue.

Chronic kidney disease is a worldwide growing problem, especially nowadays due to 3 factors very often encountered together (old age, diabetes mellitus and arterial hypertension) A multidisciplinary approach is needed to reduce this epidemic with important health implication. This needs of course well trained health partners. On the occasion of the world kidney day on March 2008, five lectures were given on the topic. The lecturers have insisted on the up to date management of chronic kidney insufficiency, a serious problem of public health. [less ▲]

Dans cette communication, G. Simons émet différentes hypothèses susceptibles d'expliquer l'hétérogénéité croissante des niveaux de maîtrise en langue dans le secondaire et en Bac 1 à l'Université et propose quelques pistes de solution pour tenter de gérer celle-ci. Il se penche ensuite sur le niveau de maîtrise des élèves en langues étrangères dans le secondaire, fournit quelques éléments pouvant expliquer une "baisse de niveau", et esquisse quelques solutions pour améliorer ce niveau. La conclusion de cette communication présente une liste de mesures qui pourraient être prises pour optimiser l'enseignement des langues dans le secondaire et donc faciliter la transition des étudiants dans l'enseignement supérieur/universitaire.

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 ▲]

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.

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 ▲]
