The Aquapôle of the University of Liège has been involved in environment modelling for more than 20 years. Its R&D unit focused on the domain of surface water, targeted to water quality. One of its environmental models, called PEGASE (Planification Et Gestion de l’ASsainissement des Eaux), French acronym for ―Planning and management of water purification‖ is devoted to the characterization of the environmental state of surface water, at the scale of a whole watershed, basin and district. The software has been used operationally in several countries like France and Benelux, but several calculations have also been performed at international level for the international commissions in charge of the Scheldt and the Meuse. PEGASE model requires as input, at least data like digital terrain models, water flow, water level and other hydrodynamic measurements in some geo-localized points, diffuse loads properties, ecological model data (to characterize bacteria, phytoplankton, zooplankton, macrophytes, shells, etc…), chemical discharges (from industry and cities) and treatment plant effect. The output of the software consists in tables, graphs and maps, showing the state of various calculated parameters of quality (DO, BOD, COD, N, P, Chla,… + indices) either at a specified time, along the river, or the temporal evolution at a given point. It provides printed maps or animations of the evolution of the results on the basin. The software is able to simulate non stationary scenarios from a local scale, up to a global scale i.e. a few km² to hundreds of thousands km² and handles the entire river tree (hundreds to thousands of water bodies). Some results of the model are already used to populate the SoE-Wise databases. On another hand, the model is a tool to validate and check consistency of SoE-Wise data at district (and thus international) level. The flexibility of the model enables to choose the time (daily to yearly periods) and spatial (watershed, water body, district, region, country …) scales of the expected results. PEGASE is also a full-scale operational tool for WFD implementation and WISE databases. This means that our partners handle a software (also known as the model) directly usable – and of direct help – in the implementation of the WFD and other water related directives. The model allows the member states to compare efficiently the collected international WISE data and populate database with relevant model results. We propose not only to read the data directly from the database to avoid manipulation mistakes, but also we propose to generate output data in a format directly exploitable by WISE databases administration.

Dehydration and major diarrhea in young infants is mainly linked to infectious diseases. However in case leading to denutrition and growth retardation, metabolic causes or malabsorption should be evocated. We report here the case of a few days old infant admitted for early recurrence of liquid stools and vomiting. XX is born at term (3450 grams, 51 cm) after an uneventful pregnancy. Consanguinity has been reported in the family. He was breastfed but presented rapidly liquid stools and vomiting. At 10 days old he was first admitted for dehydration, loss of weight below his birth weight (2900 grams) and severe hypernatremia. Semi elementary diet led to some improvement but he was readmitted at the age of one month for similar even worse symptoms including abdominal distension and explosive stools. Complementary investigations have excluded infection, parasitosis, malformation and immune deficits. Different diet formulas were tried with no significant benefit what led to the placement of parenteral nutrition thanks to which weight was gained. Hypothesis of peculiar carbohydrate malabsorption was made and the following tests have been carried out: -Clinitest: presence of reducing substances in the stools. -Lactose Breath test: between 15 and 90 ppm H2 with a peak value at 90 ppm H2 after 90 minutes. -Duodenal biopsy: normal histology; normal activity of lactase, maltase, saccharase-isomaltase. Considering the normality of these enzyme activities, hypothesis of “Na-dependant glucose-galactose transporter” deficit was put forward. This was confirmed according to the results of HGPO and glucose breath test. Search for SGTL1 gene mutation is still in progress. In conclusion despite of the huge progresses made at molecular biology level, clinical observation remain essential to the diagnosis of malabsorption. Precise reporting of the used milk formula and comparative analysis of their composition can orient the diagnosis and help to select the most accurate molecular test. Here, analyses exclude every enzyme activity deficiencies. Carbohydrate malabsorption from first days of live can be linked to a glucose-galactose transporter deficiency due to a SGLT1 mutation (chr 22). This autosomal recessive disorder has only been reported 200 times until now. [less ▲]

Mon intention est de revenir sur un aspect tout à fait particulier du débat entre la phénoménologie et la psychologie de Natorp, à savoir l’écart entre une théorie « statique » et une théorie « génétique » des essences (eidè) ou, pour reprendre l’expression de Natorp, entre un « platonisme statique » et un « platonisme génétique ». Avec cette opposition en tête, j'examine le contentieux qui oppose Reinach à Natorp, à partir de la recension de la "Psychologie générale" rédigée par Reinach. Je focalise mon attention sur les thèses natorpiennes suivantes: (1) Le Je pur est inobjectivable et ne peut être décrit – à quoi Reinach objecte que le Je pur est une donnée phénoménologique, un phänomenologischer Befund; (2) La distinction entre acte et contenu est relative – à quoi Reinach objecte qu’elle est absolue; (3) La distinction entre contenu et objet est également relative – à quoi Reinach objecte que cette distinction est utilisée de façon équivoque mais doit être entendue comme absolue en un sens au moins.

In opposition to traditional machining in which part is manufactured by material removal, rapid prototyping techniques allow parts manufacturing by material addition. The part is built layer-by-layer and the sum of all layers creates the part. Currently, several techniques exist. They use different kind of materials (metals, ceramics, polymers) and technologies (laser melting, laser polymerising, 3D-printing, cladding, ...). Some of these techniques can deal with nanometric particles. In the case of which a near net shape part is built and must be sintered after shaping, the addition of nano-particles can be useful for sintering by increasing specific surface and reactivity of the batch or by improving the properties of the material. An overview about techniques of rapid prototyping allowing the processing of nanomaterials will be discussed. Tests have been done using Optoform process. This process uses a laser to polymerize a paste made of photo-curable resin loaded with powdered material. Nano-particles can be added and stabilized in the paste. In this presentation, the results obtained with both systems Al2O3 + nano Zr02 and SiC + Nano SiC will be discussed. [less ▲]

The main source of atmospheric mineral dust is the Sahara and its desertified margins that produce about half of the yearly global mineral dust. Saharan dust is often transported far away to the sources and causes air quality deterioration impacting northwards the Mediterranean and Europe, westwards crossing the Atlantic Ocean to the United States, the Caribbean and South America, and southwards to the Gulf of Guinea. Saharan dust storms can lead to particulate levels that exceed internationally recommended levels and transport allergens, including bacteria and fungi. Therefore special attention is paid to dust storms as such mineral particulate matter air pollution may be a serious health threat in various regions of the world because it may promote respiratory infection, cardiovascular disease and other ailments.

Recent advances in the development of interferometric instruments coupled to long baseline facilities such as the VLTI allow us to observe astronomical targets at the milli-arcsecond scale. In the context of the study of massive stars, this new tool is likely to provide crucial information on the multiplicity of massive stars, and on interactions in colliding-wind binaries. In this context, our group is leading observation campaigns with the VLTI aiming at investigating massive multiple systems. I will briefly present these campaigns and discuss prospects for observations with next generation instruments such as the VLTI-Spectro-Imager (VSI). [less ▲]

Simbol-X is a mission initially driven by the French and Italian space agencies. This is a formation flying satellite whose main interest is an unprecedented imaging and spectral capability, with a high sensitivity at energies between 10 and 80 keV. This space observatory is especially designed to study acceleration processes in astrophysical sources, along with extreme physics under relativistic conditions. I will briefly present the current status of the mission. I will also discuss prospects for future observations of massive stars with Simbol-X, aiming at probing the physics of particle acceleration in colliding-wind massive binaries. [less ▲]

In various species a relationship between oocyte maturity and morphological characteristics of oocytes has been established. To our knowledge, immature oocyte aspect under light microscopy has been paid little attention in the equine. The aim of the study is to give a general description and analyse microscopic parameters of immature oocytes. Follicles from abattoir ovaries are punctured after measurement of their diameter and their cumulus-oocyte complexes are recovered. Different characters such as oocyte diameter, cumulus aspect, granulosity and polarity of ooplasm are observed under light microscopy. No correlation between estral activity, follicle maturity, cumulus cells aspect, polarity and granulosity of ooplasm was observed. Thickness of zona pellucida differs between oocytes with polar or non polar ooplasm. No correlation was observed between follicle diameter and oocyte diameter and none of the other studied parameters showed an influence on oocyte diameter. Results show that no character of oocytes observed under light microscopy can be related to follicular origin or to any other character. Further studies have to be done to compare these immature oocytes with mature oocytes and to find the ultra-structural origin of characters observed under light microscopy. [less ▲]

Deux caractéristiques importantes de l’investissement en exploration ou production pétrolière sont les montants financiers très importants en jeu et les incertitudes élevées. Pour ces raisons, l’analyse du risque devrait être mise en oeuvre dans le processus d’évaluation et de sélection des projets. En fonction de leurs ressources disponibles, les compagnies pétrolières sélectionnent un ensemble de projets sur la base de certains critères : la valeur actuelle nette, le taux de rendement interne, l’indice de profitabilité, etc . . . Cependant, ces critères se révèlent insuffisants vu, d’une part, l’absence de la notion du risque qui est un élément essentiel de l’industrie pétrolière, et d’autre part, l’omission des interactions entre les différents projets. Dans ce travail, afin de pallier aux insuffisances de l’approche traditionnelle, nous appliquons une variante de la méthode de Markowitz afin de déterminer le portefeuille optimal de projets d’exploration ou production qui assure le meilleur compromis risque minimum-rendement maximun sous les diverses contraintes auxquelles l’entreprise est confrontée. Un cas pratique d’application de cette méthode à la sélection de projets d’exploitation pétrolière en Mer du Nord est présenté. Ce cas pratique permet d’illustrer l’influence du facteur prix du brut sur le choix du portefeuille. [less ▲]

L’exploration et le développement d’un champ pétrolier font face à de nom- breuses incertitudes liées aux rendements et aux coûts tout au long du cycle de vie du pro jet. A titre d’exemple les réserves, les investissements, les coûts opératoires, la production et le prix du pétrole sont souvent incertains. En conséquence, Il difficile de prévoir les cash-flows même pour les pro jets pétroliers les plus simples. Différentes méthodes sont disponibles pour aider les décideurs à évaluer les incertitudes, et réduire le risque des opportunités d’investissement en amont pétrolier. La simulation a été reconnue comme un outil d’analyse de risque et de prise de décision en évaluation de pro jets d’investissement en amont pétrolier au début des années 60. Aujourd’hui pra- tiquement toutes les grandes compagnies pétrolières ont incorporé la simulation dans leurs études de pro jets. Dans cet article, nous essayons d’expliquer les critères d’évalua- tion et d’analyse du risque de pro jets d’investissement en amont pétrolier basés sur les cash-flows et de montrer comment la simulation de Monte Carlo peut être utile dans ce cadre.

This work considers the problem of the optimal design of an hydrogen transmission network. This design problem includes the topology determi- nation and the dimensioning problem. We define a solution method that simultaneously looks for the least cost topology of the network and for the optimal diameter of each pipe. These two problems were generally solved separately these last years. The application to the case of development of future hydrogen pipeline networks in France has been conducted on several urban areas. [less ▲]

Two important characteristics of petroleum exploration and production investment are the high nancial amounts and uncertainties. For these rea- sons, the risk analysis should be implemented in the projects evaluation and the selection process. Depending on their available resources, petroleum companies choose a number of projects on the basis of some criteria: the net present value, internal rate of return, pro tability index However, these criteria appear to be insu cient if we consider, on the one hand, the ab- sence of risk idea which is an essential element of the petroleum industry, on the other hand the omission of the correlations and interactions between di erent projects. In this paper, in order to make up for the lacks of the traditional approach, we apply a variant of Markowitzs method to deter- mine the e cient portfolio exploration and production projects that insure the best compromise minimum risk-maximum return under the di erent constraints faced by the company. A practical application of this method about selection of petroleum exploration projects in the North Sea is pre- sented. This practical case illustrates the in uence of the crude price in the choice of the portfolio. [less ▲]

Compared to bright star searches, surveys for transiting planets against fainter (V = 12 18) stars have the advantage of much higher sky densities of dwarf star primaries, which afford easier detection of small transiting bodies. Furthermore, deep searches are capable of probing a wider range of stellar environments. On the other hand, for a given spatial resolution and transit depth, deep searches are more prone to confusion from blended eclipsing binaries. We present a powerful mitigation strategy for the blending problem that includes the use of image deconvolution and high-resolution imaging. The techniques are illustrated with Lupus-TR-3 and very recent IR imaging with PANIC on Magellan. The results are likely to have implications for the CoRoT and KEPLER missions designed to detect transiting planets of terrestrial size. [less ▲]

From recent high-accuracy transit timings measurements, we discard the 5 M_earth planet recently proposed by Ribas et al. (2008). Thanks to a combined radial-velocity and transit timings overview we also define a mass/period domain in which a secondary planet may be found in the system. We also show that timings obtained until now, although not sufficient to remove degeneracies on mass and period, can still restrict the parameter space of the potential secondary planet. [less ▲]

We have analysed rotation modulated light-curves of active giants observed with CoRot using spots model. Preliminary results suggest an increase of the surface spot coverage with decreasing rotation period. A maximum of the surface spot coverage seems to occur on giants with effective temperature around 5100 K. Confirmation and interpretation of these preliminary results require groundbased follow-up observations to measure activity indicators, to identify binary systems, and to determine the stellar parameters and evolutionary status of the sample giants.

The Vocontian Basin of SE France was formed along the northwestern border of Tethys during Mesozoic times. Mainly known for its rich ammonite fauna, this basin has also yielded Jurassic and Cretaceous ichthyosaur fossils. The specimens discussed here were discovered in lower Toarcian limestone and marl successions in the vicinity of Digne-les-Bains, High-Provence Alps. One of best-preserved specimens is identified as Suevoleviathan sp., a relatively rare genus previously reported only in the German basins. The specimen is fairly complete but crushed and embedded in limestone from the Falciferum ammonite zone. Because the skull is too damaged to see bone sutures, assignation to this genus is mostly based on fin and coracoid morphology. Along with this specimen, a premaxilla and paddle elements of Eurhinosaurus longirostris and possible Stenopterygiidae centra were found in nearby black marls of the Exaratum ammonite subzone (Falciferum zone, Lower Toarcian; see Floquet et al., 2003 for a detailed stratigraphy). These soft marls were deposited in anoxic waters and are coeval with the Posidonia shales of southwest Germany, the Jet rock formation of northeast England and Grandcourt shales of Luxembourg, which allows faunal comparisons between these basins. The localities from the Vocontian Basin are closer to the Tethys than other sites where Toarcian identifiable ichthyosaurs have been found in Europe. Nevertheless all identifiable specimens from the Vocontian Basin are also identified in other basins across Europe. It suggests that Toarcian ichthyosaurs had wide palaeogeographical distributions and were highly mobile swimmers, perfectly adapted to open marine environments. [less ▲]

The tropical rain forest is maintained thanks to a precarious balance placed under the yoke of interactions between the various animal and plant species which compose it. Among them we can find those implying plants and frugivores. Although its diet is largely frugivorous, the pigtailed macaques (Macaca nemestrina leonina) have often been categorized as seed predators. However their morphology, behaviour and ecology suggest they could actually be a key-species in the dispersion of many plant species. A preliminary study by Latinne & al (2007) supported this hypothesis. The study we are planning now in continuity of Latinne’s study will take place in the Khao Yai National Park, Thailand, for three years and will focus on a troop habituated to humans. In order to establish the importance of the pigtailed macaques in the maintenance and the regeneration of the tropical rain forest, we will try to evaluate their capacity of being good seed dispersers. To do so, we will study: 1) the spatiotemporal distribution, the productivity and the characteristics of the plant species present on the home range of the studied troop, 2) the ranging patterns of the macaques within their home range, 3) their feeding behaviour, notably the fruit selection and the various modes of processing seeds, and finally 4) their impact on the viability and the germination potential of seeds. This study will require both direct observations of the macaques and semi-experimental procedures in the field, as well as laboratory control of some seed parameters. We hope the clarification of the macaques’ seed dispersal behaviour would help to re-evaluate their conservation status by recognizing them a paramount role in the maintenance of the tropical rainforest.

This paper addresses image annotation, i.e. labelling pixels of an image with a class among a finite set of predefined classes. We propose a new method which extracts a sample of subwindows from a set of annotated images in order to train a subwindow annotation model by using the extremely randomized trees ensemble method appropriately extended to handle high-dimensional output spaces. The annotation of a pixel of an unseen image is done by aggregating the annotations of its subwindows containing this pixel. The proposed method is compared to a more basic approach predicting the class of a pixel from a single window centered on that pixel and to other state-of-the-art image annotation methods. In terms of accuracy, the proposed method significantly outperforms the basic method and shows good performances with respect to the state-of-the-art, while being more generic, conceptually simpler, and of higher computational efficiency than these latter.

The B1.5 II-III star HD 180642 is the only known Beta Cephei star in CoRoT’s core programme. To complement the space data of this target, both ground-based photometric and spectroscopic data were collected, to which we added several archival observations. In this talk, we describe our results from a full integration of CoRoT and intensive ground-based observations. The star is a non-linear dominant radial mode pulsator for which low-amplitude modes are detected for the fi rst time. A few of the latter are observed in our ground-based datasets so that a mode identifi cation for them is possible. To this end state-of-the-art techniques are adapted to be applied to a star with a highly non-linear behaviour of the radial mode. Additionally, a careful interpretation of the CoRoT lightcurve helps to identify the wavenumbers. Besides this outcome, the Van Hoof effect for the dominant mode is investigated and the stellar parameters and chemical abundances are determined. All this information is to be used as additional constraints to the CoRoT pulsation frequencies, for asteroseismic modelling of this Beta Cephei star. Additional abstracts cover the lightcurve modelling of this pulsator (Degroote et al.) as well as seismic modelling (Thoul et al.). [less ▲]
