La place du sport à l'école fait l'objet de nombreuses discussions et réflexions. Surtout à l'approche de grands rendez-vous électoraux ou à l'issue d'événements sportifs planétaires tels que les Jeux Olympiques. D'aucuns considèrent que le sport devrait être plus largement soutenu et intégré à la formation scolaire. Dans cet exposé, nous attirerons l'attention des participants sur la nécessité de s'intéresser encore davantage à un concept qui dépasse le sport et est ancré dans le développement d'une société plus saine: l'activité physique.

Numerous B stars on the main sequence are found to be variable. These stars have a relatively simple structure, and yet they present some very interesting challenges. It is important to understand these stars before we can expect to be able to understand stars which have a more complicated internal structure. Asteroseismology of B stars has made considerable progress in the last few years, thanks to the observations obtained from large multisite campaigns, and it is now possible to determine global parameters for these stars such as their masses, ages, metallicities, with very high accuracy. Many variable B stars are also observed with the CoRoT space mission, and statistical studies may become possible in the near future. Detailed studies of the oscillation spectra of β Cephei stars have already allowed to put some limits on the overshooting parameter, and this overshooting parameter is found to vary from one star to the next. Some β Cephei stars are found to present differential rotation in their envelopes, while others are compatible with solid body rotation. Some B stars present nitrogen enhancement, even though they are very slow rotators. The instability strips of B stars differ depending on the composition and the opacity tables adopted. Microscopic diffusion and radiative accelerations could produce an accumulation of iron-group elements in some layers of these stars. Hybrid pulsators, showing both β Cephei and SPB pulsations have been observed. Some of the best observed stars have pulsation spectra which still cannot be reproduced by modelling. Here I review the present status of the observations and of the modelling of β Cephei stars, emphasizing both the successes reached and the questions and problems which remain open today. [less ▲]

In the study of stars, the high energy domain occupies a place of choice, since it is the only one able to directly probe the most violent phenomena: indeed, young pre-main sequence objects, hot massive stars, or X-ray binaries are best revealed in X-rays. However, previously available X-ray observatories often provided only crude information on individual objects in the Magellanic Clouds. The advent of the highly efficient X-ray facilities XMM-Newton and Chandra has now dramatically increased the sensitivity and the spatial resolution available to X-ray astronomers, thus enabling a fairly easy determination of the properties of individual sources in the LMC.

The gaseous giant planets WASP-4b and WASP-5b are transiting 12-magnitude solar-type stars in the Southern hemisphere. The aim of the present work is to refine the parameters of these systems using high cadence VLT/FORS2 z-band transit photometry and high-resolution VLT/UVES spectroscopy. For WASP-4, the new estimates for the planet radius and mass from a combined analysis of our VLT data with previously published transit photometry and radial velocities are R[SUB]p[/SUB] = 1.30[SUP]+0.05[/SUP][SUB]-0.04[/SUB] R[SUB]J[/SUB] and M[SUB]p[/SUB] = 1.21[SUP]+0.13[/SUP][SUB]-0.08[/SUB] M_J, resulting in a density rho[SUB]p[/SUB] = 0.55[SUP]+0.04[/SUP][SUB]-0.02[/SUB] rho_J. The radius and mass for the host star are R_* = 0.87[SUP]+0.04[/SUP][SUB]-0.03[/SUB] R_o and M_* = 0.85[SUP]+0.11[/SUP][SUB]-0.07[/SUB] M_o. Our ground-based photometry reaches 550 ppm at time sampling of ~50 s. Nevertheless, we also report the presence of an instrumental effect on the VLT that degraded our photometry for the WASP-5 observations. This effect could be a major problem for similar programs. Our new estimates for the parameters of the WASP-5 system are R[SUB]p[/SUB] = 1.09 ± 0.07 R_J, M[SUB]p[/SUB] = 1.58[SUP]+0.13[/SUP][SUB]-0.10[/SUB] M_J, rho[SUB]p[/SUB] = 1.23 [SUP]+0.26[/SUP][SUB]-0.16[/SUB] rho_J, R_* = 1.03[SUP]+0.06[/SUP][SUB]-0.07[/SUB] R_o, and M_* = 0.96[SUP]+0.13[/SUP][SUB]-0.09[/SUB] M_o. The measured size of WASP-5b agrees well with the basic models of irradiated planets, while WASP-4b is clearly an ``anomalously'' large planet. Based on data collected with the FORS2 imager at the VLT-UT4 telescope and with the UVES spectrograph at the VLT-UT2 telescope (Paranal Observatory, ESO, Chile) in the programme 280.C-5003. [less ▲]

Cette publication offre un tour d’horizon des soins aux personnes souffrant de démence : un inventaire de l’offre de soins, un aperçu des problèmes, une sélection de quelques initiatives novatrices et enjeux pour l’avenir. Le premier chapitre dépeint le contexte général au sein duquel se déroulent les soins aux personnes atteintes de démence. Il décrit d’abord les évolutions démographiques en cours. Parmi ces dernières, le vieillissement de la population joue évidemment un rôle important, auquel viennent s’ajouter des phénomènes tels que la diminution de la taille des ménages ou le nombre croissant de personnes isolées. Il traite ensuite de sept tendances sociétales et scientifiques qui déterminent dans une large mesure la forme que prendront, à l’avenir, les soins aux personnes atteintes de démence. Le deuxième chapitre dresse un état des lieux de l’offre de soins disponible en termes de services, d’intervenants et de structures pour personnes souffrant de démence. L’offre de services ou de structures tant extra-muraux, trans-muraux qu’intra-muraux est riche et variée. Certains d’entre eux sont nés des besoins des personnes souffrant de démence et de ceux de leurs aidants proches et leur sont spécifiquement destinés. D’autres services s’adressent à un groupe cible plus vaste, mais s’avèrent dans la pratique d’un grand secours dans le cas de la démence. La programmation de ces soins doit suffisante. Le troisième chapitre complète le chapitre précédent, davantage axé sur l’aspect qualitatif, par des informations quantitatives. Les données chiffrées sur la programmation de l’offre de soins mettent en lumière les services réalisés en Belgique, mais aussi en Région flamande, en Région wallonne et dans la Région de Bruxelles-Capitale. Les soins aux personnes atteintes de démence constituent aussi une préoccupation pour nos décideurs politiques. Le quatrième chapitre décrit les compétences et les mesures politiques prises aux différents niveaux de pouvoir (fédéral et régional). Il présente également les principales études qui ont été menées en vue de préparer et de soutenir les politiques en matière de démence. Dans le cinquième chapitre du rapport, les auteurs se tournent vers l’avenir. Quels projets créatifs, quelles initiatives innovantes peuvent constituer des sources d’inspiration pour les soins de demain ? Une petite sélection de bonnes pratiques dans les soins aux personnes souffrant de démence y est présentée. Il s’agit de formes d’habitat et de soins à petite échelle, de groupes de rencontre pour personnes présentant un début de démence et d’initiatives novatrices dans les soins de santé mentale.

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.

The Internet has seen a proliferation of specialized middlebox devices that carry out crucial network functionality such as load balancing, packet inspection or intrusion detection, amongst others. Traditionally, high performance network devices have been built on custom multi-core, specialized memory hierarchies, architectures which are well suited to packet processing. Recently, commodity PC hardware has experienced a move to multiple multi-core chips, as well as the routine inclusion of multiple memory hierarchies in the so-called NUMA architectures. While a PC architecture is obviously not specifically targeted to network applications, it nevertheless provides high performance cheaply. Furthermore, a few commodity switch technologies have recently emerged offering the possibility to control the switching of flows in a rather fine grained manner. Put together, these new technologies offer a new network commodity platform enabling new flow processing and forwarding at an unprecedented flexibility and low cost. [less ▲]
