Des séries de cas de myopathies atypiques ont été décrites entre 1986 et 1995 chez des chevaux au pré en Grande-Bretagne et en Allemagne. En automne 2000, l’examen nécropsique de 5 poneys et de 7 chevaux présentés à notre Faculté avec une anamnèse soit de signes cliniques suggestifs de cette pathologie, soit de mort subite, a mis en évidence des lésions similaires à celles précédemment décrites. De même, en avril 2001, deux poneys morts au pré après avoir présenté des symptômes évocateurs de myopathie atypique nous ont été référés pour autopsie, et des lésions de même nature ont été mises en évidence. Au total, entre les mois de novembre 2000 et avril 2001, outre ces 14 animaux présentés à notre Faculté, nous avons recensé, suite aux contacts téléphoniques avec les vétérinaires praticiens, 29 cas suspects de myopathie atypique en Belgique. Tous les chevaux et poneys atteints étaient au pré au moment du début des signes cliniques et aucun d’entre eux n’avait été récemment soumis à un exercice. Dans différents cas, la pathologie atteignait, simultanément ou à quelques jours d’intervalle, plusieurs chevaux pâturant sur un même pré. Ils étaient d’âge, de race et de sexe variables. A notre connaissance, la Belgique n’a été touchée que dans sa partie Sud et la pathologie semble associée à des conditions météorologiques particulières. Les animaux étaient le plus souvent retrouvés couchés et présentaient des difficultés importantes voire une incapacité à se relever. La conscience semblait toujours intacte, l’appétit était en général conservé et les chevaux présentaient de la tachycardie, de la polypnée et une myoglobinurie importante. Certains chevaux présentaient de la dysphagie et/ou un souffle ou une arythmie cardiaque. Lorsqu’une analyse de sang a été réalisée, elle a démontré une augmentation très sévère des enzymes musculaires. De la congestion et de l’œdème pulmonaires, une dégénérescence des fibres musculaires squelettiques atteignant surtout les muscles respiratoires et posturaux, et une dégénérescence plus modérée des fibres cardiaques ont été mis en évidence à l’examen histopathologique . Tous les examens virologiques, bactériologiques et toxicologiques réalisés post-mortem se sont jusqu’à présent révélés négatifs. Ces observations concordent avec les cas de myopathie myoglobinurique atypique décrits jusqu’ici en Grande-Bretagne et en Allemagne, dont l’étiologie demeure à ce jour inconnue. [less ▲]

Background: Emergence of erythromycin (Er) and clindamycin (C) resistance (R) observed in GBS, is currently becoming recognized. Methods: Clinical isolates were obtained from a Belgian surveillance for invasive GBS disease in newborns and adults in 1996-1998 (N1=235) and from consecutive specimens submitted, during 1999-2000, to the University hospital of Liege (N2=165). MICs of Er were determined buy using Etest® strip (interpretive criteria of NCCLS). Furthermore, for the ErR isolates, the inducible (iMLS), constitutive (cMLS) and M phenotypes were assessed by disk diffusion and by a double-disk test; the distribution of genes encoding RNA methylases and efflux pumps was investigated by PCR. Results: Of the N1 and N2 isolates, 16 (6.8%) and 19 (11.5%) were respectively R to Er. Among these 35 ErR isolates, 21 (60%) exhibited the cMLS phenotype. They demonstrated a high level R to Er with MICs ranging from 16 to >256 mg/L. The ermB gene was harbored by 19/21 isolates, the ermTR gene by 1 isolate and both ermB and ermTR were present in another isolate. The iMLS phenotype was observed in 10 (29%) ErR isolates; the ermTR gene was present in all isolates except one harboring an ermTR gene. These strains demonstrated low level of R to Er, with MICs of 1-12 mg/L. All 4 isolates (11%) expressing an M phenotype, displayed low level R to Er alone (MICs, 2 mg/L) and were positive for the mefA/B gene. Conclusion: In Belgium, by year 2000, prevalence of R to macrolide in GBS exceeded 10%. R was mainly caused by target-site modification (ermB, ermTR) mechanisms; efflux (mefA/B) R mechanism was also prevalent among the isolates tested. These results indicate the possibility of inappropriate prophylaxis or therapy using C or E as the recommended alternatives in penicillin-allergic patients. [less ▲]

We show an active application to build bidirectional multicast trees, based on the dynamic deployment of agents on top of an active network infrastructure, and interconnected by unicast. Such trees are used to build a repair service that seeks to maintain application-level connectivity in the presence of network-level multicast failures. Reflector trees are built on demand in a decentralized way, using three elementary agent operations: clone, migrate, and merge. They terminate automatically when no longer needed. In this paper we show how agents make decisions on which set of operations to use in order to produce a low cost tree configuration, taking node and link resources into account. [less ▲]

The design and the follow-up of a once-through circulation boiler differs from the design and the follow-up of a conventional boiler. A specific thermodynamic model has to suit very high pressure, sub- and supercritical steam properties. Mathematical models have to be adapted to account for the disappearance of the conventional economiser, boiler and superheater. Empirical equations corresponding to each part of the traditional boiler are no more possible. In a once-through heat recovery boiler the location of the boiling point is no more fixed. General equations have to be used for each tube of the boiler. The mathematical complexity as well as the number of equations is increased. This paper presents one subcritical 180 bar once-through heat recovery boiler model. Comparison with usual boilers in terms of mathematical results are presented, including the description of a specific mathematical model, especially developed, using the Belsim-VALI software, to represent a once-through boiler.

Les difficultés d'acquisition et de développement du langage oral des personnes retardées mentales, et plus particulièrement, de celles atteintes d'un retard mental d'origine génétique, sont, à l'heure actuelle, reconnues mais malheureusement encore mal connues. Il existe en effet une grand variabilité inter- et intra-syndromes qu'il est aujourd'hui important d'étudier et ce dans une perspective d'intervention adaptée et efficace. Les recherches menés depuis quelques années dans le domaine de la spécificité syndromique suggèrent que les développements et les fonctionnements cognitif, langagier, mnésique, perceptuel et attentionnel diffèrent considérablement d'un syndrome à l'autre. Jusqu'au début des années 1990, on envisageait le développement des personnes présentant un retard mental (plus particulièrement modéré) en référence à un modèle dit "prototypique" : le syndrome de Down ou trisomie 21.

We propose an improvement of our RLS (Receiver-driven Layered multicast with Synchronization points) protocol, called CIFL for “Coding-Independent Fair Layered mulaticast”, along two axes. In CIFL, each receiver of a layered multicast transmission will try and find the adequate number of layers to subscribe to, so that the associated throughput is fair towards TCP and stable in steady-state. The first improvement is that CIFL is not specific to any coding scheme. It can work as well with an exponentially distributed set of layers (where the throughput of each layer i equals the sum of the throughputs of all layers below i), or with layers of equal throughputs, or any other scheme. The second improvement is the excellent stability of the protocol which avoids useless join attempts by learning from its unsuccessful previous attempts in the same (or better) network conditions. Moreover, the protocol tries and reaches its ideal TCP-friendly as soon as possible by computing its target throughput in a clever way when an incipient congestion is confirmed. [less ▲]

System identification methods for nonlinear dynamical systems could find uses in many applications such as condition monitoring, finite element model validation and stability determination. The effectiveness of existing nonlinear system identification techniques is limited by various factors such as the complexity of the system under investigation and the type of nonlinearities present. In this work, the Constant Level Identification approach, which can identify multi degree-of-freedom systems featuring any type of nonlinear function, including discontinuous functions, is validated experimentally. The method is shown to yield accurate identifications of an experimental dynamical system featuring two types of stiffness nonlinearity. The full equations of motion are accurately extracted, even in the presence of a discontinuous nonlinearity. [less ▲]

The PACS Grating Assembly consists of a flat ruled grating of 320x80 mm²; its positioning mechanism; and launch-locking system. The Grating Assembly is part of the PACS Focal Plane Unit (FPU) and is operated at liquid helium temperature (4K). It is remote-controlled from the Detector & Mechanism Controller (DEC/MEC), which is located on the Herschel Service Module. The grating shall be capable of accurate positioning (4 arcsec) within a large angular throw (40 arcdeg) and restricted dissipation to the 4K heat sink (< 5 mW). The development of the Grating mechanism controller has urged the need for a cryogenic simulator of the Grating Assembly with regard to the large change in value of mechanical and electrical characteristics between room temperature and liquid helium temperature. The simulator consists of a functional prototype of the Grating Assembly and a dedicated helium cryostat with appropriate interfaces. The test cryostat is a homemade facility (CSL) designed to cool down the prototype (and subsequent models) to liquid helium temperature. The test set-up also provides relevant instrumentation such as cryogenic temperature read-out, electrical feedthroughs toward the payload and optical viewport. [less ▲]

A number of different identification methods are considered as candidate approaches to undertake online flight flutter testing. Rather than flying the test aircraft to a new flight condition and then performing a data analysis at a constant flight condition, it is shown how it is feasible to track changes in frequencies and damping ratios as the flight speed is increased. It is also possible to provide an updated estimate of the predicted flutter speed, giving the flight engineers added confidence in the margin of safety. Both frequency and time domain methods are evaluated on a simulated 3 DOF aeroelastic system. These preliminary results show that such an approach is feasible although further work is required to determine the best testing and analysis approach. [less ▲]

A new spectral approach for identification of multi-degree-of-freedom nonlinear systems, called the conditioned reverse path method, has recently been introduced. The key idea of this method is to eliminate the distortions caused by the presence of non-linearities in frequency response functions. Conditioned frequency responses are then computed and yield the underlying linear properties without influence of non-linearities. The non-linear coefficient is estimated in a second step. The aim of the paper is twofold. Firstly, the conditioned reverse path method is described in details together with the spectral conditioning techniques. Secondly, the ability of this technique to identify the behaviour of an experimental cantilever beam with a geometrical non-linearity is tested. [less ▲]

In order to investigate the soot reduction potentialities of DMM (called also methylal) addition in an overall lean diffusion flame, tests have been carried out on our experimental fuel oil boiler fitted with a burner equipped with a spill-return atomiser. The tests have been performed in steady-state regime without and with DMM addition (4% on mass basis). The two firing rates (low and high firing rates) of the burner have been adjusted successively. The flame emission was recorded by means of a photodiode, sensible in the visible region of the wavelength spectrum. The axial profiles of the flame emission obtained show clearly that an addition of DMM in the fuel oil leads to a decrease in the flame emission and thus a soot reduction. The NOx and CO emissions (measured at the chimney) and the thermal efficiency of the boiler were not significantly affected. [less ▲]

This paper proposes a time domain simulation tool combining Full Time Scale (FTS) simulation in the short-term period following a contingency and Quasi Steady-State (QSS) approximation for the long-term phase. A criterion is devised to automatically switch from FTS to QSS simulation as soon as sufficient damping of short-term dynamics is reached. Various comparisons with FTS simulations have been performed on the Hydro-Qn6bec system. The proposed method is shown to combine accuracy of FTS with computational efficiency of QSS. Sensitivity of simulations to load model and the need for updating the whole model with frequency variations are also discussed. [less ▲]

In this paper, we address the problem of transporting vital commodities and emergency personnel during the response stage of a disaster relief operation by integrating fuzzy linear optimization and the principles of scenario analysis. We treat this transportation system as a probabilistic multi-commodity multi-modal network flow problem and first develop a fuzzy model that allows the satisfaction of demand requirements through different supply nodes over a fuzzy network. Since the available information in case of disasters is generally vague and imprecise about the values of model parameters, fuzzy linear optimization is employed to deal with this uncertainty and to generate different scenarios depending upon the preferences of the decision maker. Then these scenarios are handled within the framework of the scenario analysis by defining a scenario as a joint realization of the uncertain parameters. Here, scenario analysis method can be considered as a search for a robust solution that guarantees the maximum satisfaction of demands with the minimum transportation cost. [less ▲]

Microlensing consists in two major effects: (1) variation in the apparent position of the background sources (astrometric component) and (2) flux variations of the background sources (photometric component). While the latter has been extensively used in the search for dark objects in the Galactic disk and halo (projects like MACHO (Alcock et al, 1997), EROS (Derue et al, 1999), OGLE (Paczynski et al, 1994)), the first effect has not yet been part of a systematic observational program, simply because the observations of very slight displacements in the positions of background sources requires an astrometric accuracy which current telecopes do not yet provide. We investigate here whether the astrometric accuracy of GAIA could enable such measurements and, as a consequence, enable new, direct and original measurements of the mass of nearby stars. [less ▲]

Within the Southern Ocean, amphipods have achieved a conspicuous adaptative radiation which gave rise to the development of numerous feeding strategies (Jazdzewski et al. 1996; Dauby et al. in press; De Broyer et al. in press). The discrepancy between the ecological significance of amphipods in the Antarctic and our poor knowledge of their ecofunctional role calls for a more detailed investigation of their importance in this ecosystem trophodynamics. This study focused on the eight amphipods species which were collected and from which isotopic and lipidic (when available) (Graeve et al. in press) compositions were compared to their respective gut contents previously described (Dauby et al. in press). The interest of both first techniques rely upon the direct relationship between the isotopic signatures and the lipid composition of organisms and those of their diet (De Niro and Epstein 1978, 1981; Peterson and Fry 1987; Graeve et al. 1994; Cripps et al 1999). Amphipod stable isotope ratios and fatty acids composition correspond rather accurately to the trophic classification based on gut contents and attest to their high spectrum of feeding types. Since the fundamental difference between the approaches to diet studies is the time scale each method addresses, this coincidence indicates that there would be no significant changes in feeding strategies over time. Three levels of the food web are covered by the eight species and, instead of belonging strictly to one trophic category, amphipods display a continuum of values from the suspension-feeder to scavengers.

The PC software AMCE proposes building actors a Multiple Criteria Decision Aid procedure (MCDA) to optimise the building envelope about cost and energy performances, during the sketch design. Two main modules are linked, where the user interactively goes: - a first one manages parameters describing the project requirements; - a graphic pen-based module allows to draw the sketch; it calculates geometric parameter values and put them back in the first module. Permanently informed on foreseeable performances, the user can any time search for optimal scenario giving best satisfaction to one actor or most preferred compromise to the set of actors. [less ▲]

We present the properties of all the galaxies detected by ISO at 7, 15 and 90 microns in ELAIS northern fields. The spectral energy distribution (SED) of those 20 galaxies with IRAS detections can generally be well fitted by a predominant cirrus component plus a modest starburst contribution. Follow-up spectroscopy has shown that all the objects are emission-line galaxies but without a very intense star formation event. Most of the galaxies analyzed by means of optical R band photometry result to host an important exponential disk component, in good agreement with the SED IR modelling. We note that galaxies with morphological signs of perturbations seem to show slightly higher f[SUB]15[/SUB]/f[SUB]6.7[/SUB] ratios, indicating that star formation could be more important in them. One of the objects is a broad-line, radio-quiet quasar at z=1.099; its spectral energy distribution indicates that it is a hyperluminous infrared galaxy (HLIG), the first HLIG detected in the ELAIS areas.

A holographic camera is presented, which uses a sillenite crystal as dynamic recording medium. The camera operates in a pulse regime and is used to provide vibration analysis of an object. A 4 pulse real-time holographic technique was implemented to measure the amplitude and phase of the vibration. The implementation of this technique required bringing under control a Q-switched YAG laser. We present the experimental results for a metallic plate driven by a vibrating loud speaker. [less ▲]
