Réunion éducative annuelle 2010 organisée par le GNFB. Sont passées en revue les principales nouveautés concernant l'hypertension artérielle,en tenant compte de la mise à jour des recommandations de la Société Européenne d'Hypertension parue en octobre 2009.L'hypertension est-elle rare chez l'enfant? Comment la diagnostiquer et la prendre en charge? Quelles sont les causes et les particularités de son traitement? A l'autre extrême, faut-il traiter l'hypertension de la personne âgée, voire très âgée et avec quel objectif? L'adage "the lower ... the better" est-il toujours d'actualité ou faut-il craindre des tensions artérielles trop basses? La courbe en J existe-t-elle et faut-il en tenir compte? Quels sont les progrès récents dans la thérapeutique? Est-il logique d'initier le traitement par une association de 2 molécules chez certains patients? Certaines associations sont-elles préférables à d'autres? Que va nous apporter l'inhibition directe de la rénine? Doit-on s'orienter vers des thérapeutiques non médicamenteuses pour juguler certains cas d'hypertension réfractaire? Enfin, que penser des mesures ambulatoires de PA mais aussi de la rigidité artérielles proposés en première ligne, dès aujourd'hui pour les unes, demain pour les autres. Ces techniques sont-elles suffisamment validées pour être intégrées à notre pratique clinique? Quelle est leur valeur ajoutée pour le patient individuel? Les appareils fournis sont-ils tous fiables? Et la télémétrie? Telles sont quelques-unes des questions auxquelles cette réunion s'efforcera de répondre, tout en laissant une large place à l'interactivité, au partage de nos expériences respectives et aux questions posées.

Différenciation sémiologique entre les troubles de l'attention avec ou sans hyperactivité et la bipolarité dans la petite enfance. Le diagnostic de bipolarité reste peu connu des pédopsychiatres. Après les premiers symptômes il faut en moyenne 10 ans et 3 à 5 médecins avant qu'un diagnostic correct ne soit posé. Notre étude, se rapportant à 170 enfants de 18 mois à 10 ans, met en évidence une sémiologie nuancée qui permet un diagnostic rapide et précoce d'un "tempérament maniaque bipolaire" comportant sept axes sémiologiques : 1. une forme "super-énergétique", 2. la clinique du sommeil, 3. un "mal-être en situation d'être seul", 4. des couleurs affectives expressives, 5. une tendance à l'excitabilité-désinhibition-appétence, 6. la prépondérance de l'attention divergente sur l'attention convergente, 7. la tendance à l'hyperactivité. Nous évoquons pour ces sept axes leur évolution développementale jusqu'à la vie adulte. La mise en évidence d'une clinique du "mal-être en situation d'être seul" est l'élément le plus original de notre recherche, il correspond à un déficit de la capacité à demeurer seul avec soi-même au calme. Ce mal-être est à distinguer de l'angoisse de séparation, même s'il peut y avoir un continuum ; il n'est pas pathognomonique de la bipolarité mais semble en faire systématiquement partie. Dans l'ADHD (déficit d'attention avec ou sans hyperactivité) on ne retrouve que les points 1, 6 et 7, par contre les points 2, 3, 4, 5 sont spécifiques de la bipolarité. Nous proposons 4 sous-groupes sémiologiques des états bipolaires et unipolaire dans l'enfance. Différentes comorbidités possibles pourront s'ajouter, ce qui apportera d'autres accentuations cliniques. Selon le temps imparti, nous pouvons également évoquer : des métaphores explicatives et thérapeutiques ; des réflexions neurophysiologiques jointes à cette sémiologie; le pronostic qui peut radicalement changer avec une prise en charge précoce.

The aim of the present study is to compare two delignification methods (formic/acetic acid1 and soaking in aqueous ammonia) on Miscanthus x giganteus and to assess the suitability to produce cellobiose and other oligosaccharides after enzymatic hydrolysis. Oligosaccharides have recently gotten attention for their health benefits. Two methods were compared in order to quantify lignin: the acid detergent lignin method (procedure of Van Soest most commonly employed by animal scientist and agronomists for analysis of forages) and the Klason lignin procedure. Lignin concentrations in raw material determined by both methods were different; Klason lignin value (23.5%) was greater than the acid detergent lignin concentration (12.9%). Possible reasons of these results will be discussed. Pretreatment by the formic/acid mixture showed a better deliginification rate compared to the soaking in aqueous ammonia method. Results were based on Klason lignin. Analysis of the structural carbohydrates revealed that untreated miscanthus was mainly composed of glucose and xylose. Extracted pulps by both delignification methods were hydrolysed by commercial cellulases and hemicellulases. A major challenge is the characterisation of complex mixtures of lignocellulosic hydrolysates. In this study, the hydrolysis products were separated and quantified by highperformance anion exchange chromatography with pulsed amperometric detection (HPAECPAD). This method was successfully applied to the quantitative analysis of monosaccharides (glucose and xylose) and disaccharides (cellobiose and xylobiose) formed by the enzymatic hydrolysis of pretreated miscanthus. The influence of the pretreatments on the oligosaccharides yields will be presented. [less ▲]

Cette étude vise à examiner les raisons pour lesquelles la sémiotique a toujours éprouvé de grandes difficultés à élaborer une théorie des mécanismes généraux de la signification — la transversalité du sens par rapport aux différents médias est un de plus grands défis qu’elle s’est donnés — qui, en même temps, rende les énoncés analysables (en effet, le sens de ces derniers ne peut être établi que si on prend en compte la spécificité des substances de leur expression et de leur fonctionnement des culturel). D’un côté, les dernières décennies ont vu surgir des « théories de champ » (théorie de la peinture, de la photographie, du cinéma, etc.) mettant en avant la spécificité des différentes formes expressives ; de l’autre la sémiotique a produit des théories de la signification si générales qu’elles sont impuissantes à mener l’analyse de ces formes expressives (ce qui l’a amené à étudier les organisations discursives indépendamment du parcours génératif de l’expression). Les travaux du Groupe μ démontrent la possibilité de dépasser cette contradiction. S’ils y arrivent, c’est parce qu’ils affrontent la question générale de la perception — manifestation matérielle des signifiants des énoncés textuels — et la question pratique de la production du signe, sans pour autant réifier la spécificité matérielle des énoncés.

Contribution of the root system to the flowering process remains poorly studied. Part of the problem resides in its difficult isolation from the substrate, especially on adult plants. Taking advantage of an hydroponic device that allows synchronous growth and flowering of Arabidopsis thaliana (Tocquin et al., 2003), we performed global transcript profiling of roots during induction of flowering by a single long day (LD). Results were validated by real-time RT-PCR, and the expression patterns of selected probes were further analyzed in shoots and roots. Some of the genes that were identified in the microarray experiment were already known to be involved in the photoperiodic pathway of flowering in Arabidopsis, and hence were activated in both roots and shoots during the LD. These genes include, for example, components of light signaling or circadian machinery (e.g. GIGANTEA). Other genes providing new insights into the control of flowering at the whole plant level will be presented. Tocquin et al., (2003). BMC Plant Biology, 3: 2. [less ▲]

In response to ESO's call for proposals for second generation instruments for the Very Large Telescope Interferometer (VLTI), a consortium has proposed to design and develop the VLTI-Spectro-Imager (VSI). In the context of the Phase A study, a science group has prepared a science case taking advantage of the expected performances of VSI. Among several science topics, the case of dust making Wolf-Rayet binaries producing the so-called pinwheel nebulae has been considered. Here, we review the main specifications of VSI, and we provide preliminary results expected to illustrate the imaging capabilities of VSI, and the interest for the study of pinwheel nebulae similar to those formed close to well-known systems such as WR98a and WR104.

Mesozooplankton faecal pellets participate in the carbon and nutrient cycles, in the nutrition of marine organisms, and in the transport of toxins, pollutants, and sediments. The importance of this role depends on their nature and production, which are highly variable parameters that, in turn, depend on many factors. For example, a phytoplankton bloom may significantly change the nature of mesozooplankton faecal pellets because it affects their shape, content, density, and volume. The aim of the present study is to compare the eutrophic Southern North Sea and the oligotrophic Bay of Calvi in the Meditenanean Sea with respect to the seasonal variability of faecal pellet characteristics (shape, size, sinking speed, density) during bloom conditions.

Massive binaries are crucial laboratories that allow us to investigate processes occurring in quite extreme conditions, such as particle acceleration, high-energy emission, or even dust formation. All these processes are intimately dependent on binarity. Our understanding of the underlying physics strongly requires preliminary multiplicity studies likely to uncover still undetected binaries, and determine their orbital parameters. However, classical spectroscopic approaches sometimes fail to provide a solution to this issue. Long baseline interferometry turns out to be a promising complementary technique to address the question of the multiplicity of massive stars. A campaign has been initiated with the VLTI to take benefit of this technique. [less ▲]

Emerging concerns about competitiveness induce a growing number of firms to outsource their outbound transportation operations to third-party logistics providers. The resulting increase in the number of actors often leads to sub-optimal supply chain actions due to the antagonistic nature of the economic objectives of the partners. With the aim of determining possible deviations from the optimal system performance in such supply chains, this study analyzes the contractual relation between a retailer and a third-party logistics provider (carrier) using game theoretical approaches. The partners of the studied supply chain play a Stackelberg game in which the retailer is the leader and the carrier is the follower. The retailer faces an uncertain demand and needs to supply his store from his warehouse. he has the option of not meeting all the demand but must satisfy at least a minimum proportion of the fi nall demand. On the other hand, the carrier has to determine the number of trucks needed to satisfy this demand before uncertainty is resolved. Once demand is realized, if the reserved transportation capacity is insufficient, the carrier also has the possibility to requisition trucks at a higher price. We modelise the problem and propose a contract having two parameters : the quantity of transported items and the number of truck used. In our settings, the retailer is the one that submits the contract and the carrier decides if he accepts it or not. We compare this situation with a centralized model where a single decision maker takes all the decisions. [less ▲]

We currently use several advanced NMR techniques in order to fully characterize actinide ions and their complexes in water or in organic solvents. The dispersion of the longitudinal relaxation time T1 of solvent nuclei with the magnetic field (NMRD) yields information on the magnetic properties and on the dynamic behavior of paramagnetic species. 17O NMR allows the measurement of the water exchange times and 1H and 13C spectra yield information on the solution structures of the complexes and on the covalency of their coordination bonds. The application of NMR in actinide science will be illustrated with studies on the U, Np, Pu and Cm ions in different oxidation states and on their complexes. For instance, Cm3+ ion is the actinide analogue of Gd3+ but is not in a pure 8S state as indicated by much lower relaxation rates and much shortened electronic relaxation rates. In keeping with EPR studies1, Cm3+ does not have a perfectly spherical distribution of its unpaired electronic spins because of a much stronger spin-orbit coupling. Moreover, the Cm3+ relaxivity originates from three different processes: a dipolar coupling between the nuclear and electronic spins, a delocalization of unpaired electronic spins into the solvent orbitals (contact interaction) and a Curie contribution. Each process gives rise to an inflection point in the NMRD curves and the contact interaction reflects the partial covalency of the coordination bonds formed by Cm3+. A contact contribution is also observed in the NMR spectra of Cm3+ complexes. The sensitivity of NMR to the exact nature of the ground state of actinide ions is also illustrated by detailed studies on the U, Np and Pu ions in different oxidation states. For instance, a comparison of the NMRD curves of the 5f2 ions U4+, NpO2+ and PuO22+ indicates that the two dioxo cations have abnormally long electronic relaxation times. However, well-resolved 1H NMR spectra of their complexes can be obtained provided the solution species are sufficiently rigid. It will be shown that NpO2+ and PuO22+ induce dipolar paramagnetic shifts from which the solution structure can be deduced. [less ▲]

At present, sensory evaluation is not yet integrated in all labels and standards. After comparison and interpretation of the weaknesses and the strengths of the several existing methods, a methodology has been elaborated. Previous experience in off-odour measurements for environmental field investigations help us to propose a methodology based on the assessment of odour intensity and hedonic tone. Various floor covering materials were tested in the lab with a self-made instrument. The sampling procedure is based on a "Field and Laboratory Emission Cell" (FLEC). The odour of the material is compared to a 8-level butanol intensity scale generated through a vaporization chamber and 8 stainless steel capillaries distributing the diluted n-butanol to 8 sniffing ports. First results shows generally a correlation between bad hedonic tone and odour intensity. On the contrary, there are no systematic relations between VOC levels and odour perception. The less odorous materials (PVC) are also the ones with the higher level of total VOC and the linoleum had a strong odour with a low level of total VOC. The explanation lies in the chemical family composition of the emission. The PVC emission contains mainly alkanes compounds (non odorous family) whereas the linoleum contains also odorous chemical families like carboxylic acids and aldehydes. [less ▲]

Small scale farmers, in developing and in some developed countries, are faced to actual difficulties of applying pesticides accurately and safely on vegetables crops. They mainly use hand operated sprayers. As an issue, a small direct injection system based on a five meter's parallel boom layout was designed to improve chemical application. The boom layout was optimised to obtain the same minimal lag time response for the ten nozzles. The dynamic of the system was modelled using SimulinkTM as first order model with delay. Two control strategies were implemented using PID feedback control loops to monitor tracer injection (fluorescing) proportionally to simulated forward speed (from 0.6 to 1.2 m/s) and to control the constant operating pressure (constant carrier flow strategy) or the variable operating pressure proportionally to the injected chemical amount (variable total flow strategy). Different forward speed changes were induced using steps up and down, ramps, sine waves and sweeps solicitations to evaluate the control feedback. The system stability was tested for its ability to maintain the expected concentration and application rate. The results show that the lag time remains less than 3 s (dead time < 2s , time constant < 1s) and the system keeps stable for the maximal speed variation and acceleration tested (∆V=200%, a= 0.48 m/s2) which induce less than 10% variation of application rate.

Three reasons have urged the Walloon Forest Administration (Walloon Public Service) on to solicit the help of forest researchers to bring practical responses to the adaptation of its current forests management: (i) the progression of research in applied autecology, (ii) the development of software for the management and the analysis of georeferenced data (GIS technologies) and, (iii) the awareness of the potential negative impacts of climate change on forests. To answer to this request, this research aims to model the autecology of the main forest tree species at the Walloon Region scale (Beech, Oak, Norway Spruce, Douglas-fir and valuable broadleaves species). The results will be used to update current practical tools to assess the adequacy of forest tree species on sites, especially in the climate change context. The research is built into three main steps: • update the autecology knowledge for the targeted forest tree species through a state of the art; • compile and create different ecological parameters that can explain the major part of trees growth such as climatic, topographic, geologic, edaphic and phytosociological data gathered from forest plots or geodatabases. In the context of climate change, a particular attention will be brought on bioclimatic and soil moisture conditions because of their narrow link with the potential risk of trees ecophysiological stress; • model tree species reaction to environmental conditions with tree growth indicators. Three types of indicators with different spatio-temporal scales are foreseen: stand site index (30-50 years), periodic diameter growth (5-10 years) and tree-ring growth (1-3 years). The use of these three scales is justified by the interest presented by their cross-validations which are necessary for an accurate extrapolation of results to the entire region. Results should indicate the tree species behaviour, especially towards stress conditions. The integration of climatic data, provided by global climate models based on IPCC's climate scenarios, in autecological models could be used to assess the behaviour of forest stands in future climate conditions. From those results, we expect to identify and assess accurately the risky “sites-species pairs” to avoid in the context of a sustainable silviculture. Finally, results will be used to provide autecological synthesis and practical tools to help forest managers and foresters to identify the best “site-species pairs” (tree-site adequacy maps, sites catalogue and computer platform).

Electrical resistivity tomography (ERT) and self-potential (SP) investigations are currently conducted in carboniferous limestones in Belgium. The aims of this study are (1) to characterize and (2) to monitor the groundwater flow in fractured or karstic area and (3) to use these geophysical data as a help for groundwater flow model conceptualisation and inverse calibration. Large ERT profiles (320 meters) allow us to image the electrical resistivity distribution of the first 60 meters of the subsurface and to detect and characterize (in terms of direction, width and depth) some fractured and/or karstic zones expected to be less resistive. Data errors as well as indicators of resolution (resolution matrix, sensitivity matrix and DOI index) are analysed in order to calculate the depth of investigation of ERT and to avoid the misinterpretation of the resulting images. Self-potential measurements are performed along the electrical profiles and permit us to find some negative anomalies possibly related with groundwater preferential flow pathways. Since SP signals are related with the groundwater flow when taking into account the electrokinetic effect, we are able to estimate a first distribution of the water table along our profiles. These geophysical data concurrently with ‘ground truth’ geological and hydrogeological data give us a way to better understand the groundwater flow in limestone synclines of the Dinant Synclinorium geological structure. Still, further efforts are needed (1) to fully cover the syncline area and (2) to couple the SP, ERT and hydrogeological data through a more complex forward model of the electrokinetic effect of the self-potential method.

Soil respiration is a process which results in CO2 release from the soil to the atmosphere. It comprises two main components. The first one is heterotrophic respiration: CO2 is produced by soil microorganisms while decomposing the substrate. The second one is autotrophic respiration in which CO2 originates from roots and rhizospheric organisms. All the CO2 is then transported to the surface by diffusion (see Goffin et al., this session). Many biotic and abiotic factors play a role in soil respiration, making this process complex to analyze and understand. Temperature often appears as the most important driving variable. Besides that, interest in the future CO2 emissions from agricultural soils has been growing. Indeed, these ecosystems are a major concern from environmental, economic and social points of view. In particular, the choice of cultural practices and residue management techniques has a strong influence on CO2 emissions from agricultural systems. This work aims at getting to a better understanding of soil respiration in agricultural soils. To reach this goal, many semi-mechanistic models have been previously developed at very different spatio-temporal scales. We intend to adapt such an existing model to crop soils, within a spatial scale of a cultivated field and an annual temporal scale. The model will be validated by using flux measurements carried out at three different crop sites situated in the Hesbaye region in Belgium (Lonzée) and in the South West of France (Lamasquère, Auradé). The study was focused first on soil heterotrophic respiration. Within this part, short term sensitivity of this component to temperature was studied by means of a laboratory incubation experiment. This one was performed with soil samples taken at the Lonzée site. Among the many interesting results we got, it showed a clear sensitivity of soil heterotrophic respiration to short term temperature changes. In parallel, the soil heterotrophic model was calibrated on soil chamber measurements taken at the Lonzée site (Belgium). Next steps in this part of the work will be to calibrate the model using the data from the French sites, and finally to validate the model on the three sites. Afterwards, an autotrophic respiration submodel will be implemented and the results compared to field measurements carried out at the three sites. A further development could consist in simulating agricultural practices to take their impacts on CO2 emissions from crops into account. [less ▲]

The mean electron energy may be significantly different in different auroral zones. The Io tail CR is remarkably low in comparison with the high-latitude aurora and independent of its brightness (<E> ~ 50 keV or less). This is consistent with a model where the tail corresponds to an upward field aligned current closing the magnetospheric circuit in Jupiter’s ionosphere. The CR in the main oval is associated with electron energies from ~50 to several 100 keV. It is statistically positively correlated with the intensity. Brightness increase in the main oval is accompanied by hardening of the electron energy spectrum. This result is consistent with acceleration by potential drops accompanying upward field-aligned currents which carry a nearly constant particle number flux. The electron mean energy is also variable in the polar spots but it is not correlated with the main oval brightness nor its own intensity, suggesting different, uncorrelated mechanisms. Polar brightenings (duration ~ 50-100 sec, rise time ~30 sec) have been observed. They are not necessarily associated with an increase of the mean electron energy. The mean electron energy can even decrease during the intensification. No correlation is observed between changes in main oval and high latitude (polar cap) features. [less ▲]
