L’herpèsvirus bovin 4 (BoHV-4) est un gammaherpèsvirus appartenant au genre Rhadinovirus. Récemment, une étude phylogénique a démontré que le gène Bo17 du BoHV-4 codant pour un homologue fonctionnel de la C2GnT-M cellulaire a été acquis d’un ancêtre direct ou indirect du buffle africain (Syncerus caffer) il y a quelques 1,5 millions d’années (Markine-Goriaynoff, N. et al. 2003. The core 2 beta-1,6-N-acetylglucosaminyltransferase-mucin encoded by bovine herpesvirus 4 was acquired from an ancestor of the African buffalo. J Virol 77:1784-92). Dans la présente étude, deux objectifs ont été poursuivis. Premièrement, dans le but de préciser l’origine du gène Bo17 du BoHV-4, le gène de la C2GnT-M de diverses sous-espèces de buffles a été séquencé. Les sous-espèces sélectionnées appartiennent aux espèces Syncerus caffer (pour les sous-espèces caffer, aequinoctialis et nanus) et Bubalus bubalis (pour les sous-espèces River, Swamp et Murrah). L’analyse phylogénique des séquences obtenues démontre que le BoHV-4 a acquis son gène Bo17 à partir d’un ancêtre direct de la sous-espèce Syncerus caffer caffer, soit bien après la séparation des Syncerus et des Bubalus. Le second but de cette étude était de déterminer si les souches de BoHV-4 isolées en Afrique à partir de buffle africain forment un groupe phylogénétiquement distinct au sein de l’espèce BoHV-4. Dans ce but, neuf souches représentatives de l’espèce BoHV-4 (dont trois isolées de buffle africain) ont été sequencées au niveau de 5 régions réparties sur l'entièreté du génome viral. L’analyse phylogénique de ces sequences démontre l’existence d’événements de recombinaisons inter-souches survenus récemment au cours de l’évolution. En conclusion, cette étude phylogénique a permis d’étabir que (i) le gène Bo17 du BoHV-4 a été acquis d’un ancêtre direct de la sous-espèce Syncerus caffer caffer de buffle africain, et (ii) que le génome du BoHV-4 a subi par la suite des phénomènes de recombinaisons inter-souches.

More than 21,500 harbour seals were killed by Phocine Distempter Virus in the North Sea and adjacent waters in 2002. Of those more than 3,340 seals were found dead on the coast of Schleswig-Holstein. After the second seal die-off had ceased, seals were captured alive for a health check and also stranded seals were examined for their health status. Blood status and chemistry tests were performed, microbiological, parasitological, histological, serological and cytological investigations were conducted. During the first catch after the seal die-off animals seemed to be in clinically good condition although hematological disturbances (leucocytosis as well as leucopenia) were detected. Bacteriologically, Bordetella bronchisptica was isolated, a bacterium which was exclusively cultured during the seal die-off. At later catches hematological values normalized and also the normal bacterial flora was cultured from vagina and anus. The serological investigations for morbillivirus-specific antibodies revealed positive titers in 100% of the seals. Morphologically, there was no evidence for a continuing morbillivirus infection by both, histology and immunocytochemistry. The pathomorphological changes were similar to those before the epizootic including the predominance of parasitic and bacterial bronchopneumonia, emaciation and dermatitis. Contrary to the first seal die-off in 1988/89 an increased number of large skin wounds on the ventral side and infections of the umbilicus were not seen. This may indicate that the seal population in Schleswig-Holstein was generally in better health condition at the second seal die-off compared to the first one. The continued investigations will allow a further assessment of the development of the seal population in the Wadden Sea. [less ▲]

The liquid sheet characteristics as a function of the adjuvant were measured using digital images. The droplet size distribution was measured using a Malvern particle size analyser. It appears that the dynamical surface tension plays a critical role in the spray formation. Spray formulation containing Li-700, Silwet L-77, Flofix and Actirob are characterised by a lower dynamical surface tension than those containing Tensiofix D03, Trend 90, Frigate and Break-thru S240. For the three agricultural spray nozzles tested and in comparaison with pure water, the first group shortened the length of the liquid sheet before a perforation break-up mode when the second group lengthened it slightly before a wave disintegration break-up mode. The lengthening of the liquid sheet, is followed by a diminution of the VMD. [less ▲]

Until now, little attention has been paid to the processes controlling the production, dissolution and fate of biogenic calcium carbonate in the oceans. It is however well known that net deposition rates of inorganic carbon to the sediments are comparable to those of organic matter. There remains still large uncertainties concerning the production and redissolution of biogenic carbonate in the marine system and thus about the role of the carbonate pump in response to anthropogenic CO2 perturbations. The understanding of these processes is also a prerequisite to predict the response of marine organisms to global environmental changes. In the framework of the Belgian global change programme, we have developed a project devoted to the study of the inorganic carbon cycle in the Bay of Biscay where coccolithophorid blooms occur frequently. The study focuses on processes associated with the oceanic production and dissolution of calcium carbonate, by combining field investigations, laboratory experiments and modelling efforts. Remote sensing demonstrates a close relationship between vertical mixing along the continental margin and the development of the phytoplankton bloom. We will present here, results of 14C incorporation experiments used to evaluate the rate of production of organic and inorganic particulate carbon, obtained during a coccolithophorid spring bloom in the investigated area. A tentative mass balance of the carbon fluxes for this area will be presented, confirming the importance that the calcium carbonate pump may play in the oceanic system. [less ▲]

In the framework of flexible multibody systems simulation, the stability and the accuracy of the time integration process can be guaranteed by a family of implicit integrators derived from the Newmark scheme (Hilber-Hughes-Taylor and Generalized- methods). This paper deals with the extension of those reliable integrators for the simulation of mechatronic systems. In order to account for the strong coupling between the mechanism and the control system, the coupled set of equations contains mechanical and control variables. The generation of those equations, their numerical treatment and their time integration may become unmanageable for realistic control systems. In many cases, it is however sufficient to consider a weak coupling, which means that the action of the control system is treated as an external force disturbing the dynamic equilibrium. The weak coupling assumption is fully justified when a digital controller is present in the control loop. Then, the control actions exhibit discontinuous transitions at each sampling instant. The standard form of the Newmark scheme assumes continuity of the acceleration variables, and is thus not appropriate for this situation. Therefore, we propose an adapted Newmark scheme which achieves an explicit treatment of the acceleration jumps throughout the integration process, so that the proper simulation of the mechatronic system is guaranteed. The paper describes the detailed modifications of the integration algorithm. Illustrative examples are used to point out the critical situations where they prevent from substantial integration errors. [less ▲]

Optical and structural elements made of silicon carbide are increasingly found in space instruments. Chemical vapor deposited silicon carbide (CVD-SiC) is used as a reflective coating on SiC optics in reason of its good behavior under polishing. The advantage of applying ion beam figuring (IBF) to CVD-SiC over other surface figure-improving techniques is discussed herein. The results of an IBF sequence performed at the Centre Spatial de Liège on a 100 mm CVD-SiC mirror are reported. The process allowed to reduce the mirror surface errors from 243 nm to 13 nm rms . Beside the surface figure, roughness is another critical feature to consider in order to preserve the optical quality of CVD-SiC . Thus, experiments focusing on the evolution of roughness were performed in various ion beam etching conditions. The roughness of samples etched at different depths down to 3 m was determined with an optical profilometer. These measurements emphasize the importance of selecting the right combination of gas and beam energy to keep roughness at a low level. Kaufman-type ion sources are generally used to perform IBF but the performance of an end-Hall ion source in figuring CVD-SiC mirrors was also evaluated in this study. In order to do so, ion beam etching profiles obtained with the end-Hall source on CVD-SiC were measured and used as a basis for IBF simulations. [less ▲]

An enterprise network is analyzed from the viewpoint of an end-product manufacturer who receives customer orders and organises his production and supply policy so as to minimize the sum of his average holding cost and average stock-out cost. For each main component to be ordered, the producer has several possible suppliers. The arrivals of customers’ orders are random and delivery times from suppliers are also supposed random. This supply system is represented as a queuing network and the producer uses a base-stock inventory control policy that keeps constant the position inventory level (current inventory level + pending replenishment orders). The decision variables are the reference position inventory level and the percentages of orders sent to the different suppliers. In the queuing network model, the percentages of orders are implemented as Bernoulli branching parameters. A close-form expression of the expected cost criterion is obtained as a complex non-linear function of decision variables. A decomposed approach is proposed for solving the optimization problem in an approximate manner. The quality of the approximate solution is evaluated by comparison to the exact solution, which can be computed numerically in some simple cases, in particular in the two-supplier case. Numerical applications show the important economic advantage for the producer of sending orders to several suppliers rather than to a single one. [less ▲]

The Solar Atmospheric Imaging Assembly (AIA) aboard the Solar Dynamics Observatory will characterize the dynamical evolution of the solar plasma from the chromosphere to the corona, and will follow the connection of plasma dynamics with magnetic activity throughout the solar atmosphere. The AIA consists of 7 high-resolution imaging telescopes in the following spectral bandpasses: 1215Å. Ly-a, 304 Å He II, 629 Å OV, 465 Å Ne VII, 195 Å Fe XII (includes Fe XXIV), 284 Å Fe XV, and 335 Å Fe XVI. The telescopes are grouped by instrumental approach: the MAGRITTE Filtergraphs (R. MAGRITTE, famous 20th Century Belgian Surrealistic Artist), five multilayer EUV channels with bandpasses ranging from 195 to 1216 Å, and the SPECTRE Spectroheliograph with one soft-EUV channel at OV 629 Å. They will be simultaneously operated with a 10-second imaging cadence. These two instruments, the electronic boxes and two redundant Guide Telescopes (GT) constitute the AIA suite. They will be mounted and coaligned on a dedicated common optical bench. The GTs will provide pointing jitter information to the whole SHARPP assembly. This paper presents the selected technologies, the different challenges, the trade-offs to be made in phase A, and the model philosophy. From a scientific viewpoint, the unique combination high temporal and spatial resolutions with the simultaneous multi-channel capability will allow MAGRITTE / SPECTRE to explore new domains in the dynamics of the solar atmosphere, in particular the fast small-scale phenomena. We show how the spectral channels of the different instruments were derived to fulfill the AIA scientific objectives, and we outline how this imager array will address key science issues, like the transition region and coronal waves or flare precursors, in coordination with other SDO experiments. We finally describe the real-time solar monitoring products that will be made available for space-weather forecasting applications. [less ▲]

At the microscale, classical bearings such as ball bearings, sliding bearings and other pivots may be difficult to manufacture. Among all possible solutions to replace them, the notch hing seems to be very attractive through its many advantages. The major limitation is on the rotation angle. This paper presents a new simplified analytical model for the prediction of the maximum angular displacement and the angular stiffness of a notch hinge. To validate our model, an experimental set-up has been developed. [less ▲]

Predicting terminals movements in mobile networks is useful for more than one reason, in particular for routing management. A way to do such prediction is to learn the movement patterns of mobile nodes passing by an access router. In this paper, the information (e.g. layer 2 measurements) related to the different paths followed by mobiles are learned using a hidden Markov model. Simulations have been done using this method and show it can handle different layer~2 signals and collect statistical information when no such signal is available. Furthermore, the method works when no information is available and can be extended so as to guess the timing of the handoffs. [less ▲]

DBP reduction in the last 6 h of the once-daily dosing interval and 24-h mean DBP control when a dose is missed are significantly superior with telmisartan than with valsartan. Thus, telmisartan due to its longer half-life offers more sustained BP control, especially at the end of the dosing period and provides sustained efficacy in poorly compliant patients. [less ▲]

L’objectif des études synthétisées dans cette communication consiste à mettre au point une méthode in vitro, simple, fiable et respectueuse du bien-être animal, pour mesurer la fermentation des fibres dans le gros intestin du porc. Les travaux ont été réalisés en adaptant la méthode de BOISEN et FERNANDEZ à la pepsine-pancréatine pour simuler la digestion des aliments dans la première partie du tube digestif. La méthode d’incubation en seringues de MENKE et STEINGASS a ensuite été utilisée pour quantifier la production de gaz des résidus de la prédigestion. Les expériences, réalisées au moyen de porcs en croissance, ont porté sur la quantité et le mode de filtration des substrats prédigérés par la pepsine-pancréatine, l’identification d’un aliment de référence, la dilution des inoculi dans la solution tampon en seringues et la comparaison des fermentations, en utilisant comme inoculi des contenus d’intestin ou des matières fécales. Les résultats montrent que la répétabilité de la digestion in vitro par la pepsine-pancréatine est satisfaisante et que les quantités d’aliment incubées peuvent être augmentées par rapport à la méthode de référence. La filtration des résidus peut être réalisée sur creusets filtrants ou sur toile Nylon. La pulpe de betterave constitue un aliment témoin idéal. Après 24 h d’incubation, la production de gaz obtenue à partir d’inoculi fécaux dilués 20 fois dans la solution tampon est identique à celle enregistrée à partir d’inoculi intestinaux dilués 10 fois dans le même tampon.

The implantable programmable micropump is an interesting solution to treat chronic diseases such as diabetes with regular micro-injections of medicine. However, current applications of micropumps are limited by their rather expensive cost. The challenge is therefore to develop a low cost alternative by reducing the number of parts and by simplifying the assembly. As the pump and its tank will be placed under the skin in order to increase comfort, such a system should be small and reliable. In this paper, we present the micropump we developed within the framework of the 4M-µ pump interuniversity project (Methods and Means for the Miniaturization of Machines). [less ▲]

Apprendre à lire dans une langue n’interfère pas avec l’apprentissage de la lecture dans une autre langue mais prépare plutôt le terrain pour apprendre à lire dans une autre langue. Comme dans le langage oral, il peut y avoir quelques « mixing » de prononciation au niveau des mots qui disparaissent progressivement au fur et à mesure que les langues se compartimentalisent. Avec le temps, l’enfant apprendra également que des mots qui s’écrivent de la même manière dans les deux langues peuvent se prononcer de manière différente. Une recherche menée sur des enfants francophones Belges suivant un programme d’immersion scolaire en anglais et ayant appris à lire en anglais confirment ces observations. 150 enfants âgés de 7 à 12 ans fréquentant ce programme ont été testés sur leurs compétences en lecture du français (décodage et compréhension). Leurs performances (type et nombre d’erreurs, vitesse de lecture) ont été comparées à celles d’enfants francophones fréquentant un enseignement unilingue. Leurs habiletés métaphonologiques (manipulation de la rime et du phonème) ont également été testées. [less ▲]

For delta Scuti stars, phase differences and amplitude ratios between the relative effective temperature variation and the relative radial displacement can be derived from multicolor photometric observations. The same quantities can be also calculated from theoretical non-adiabatic pulsation models. We present here these theoretical results, which indicate that non-adiabatic quantities depend on the mixing length parameter alpha used to treat the convection in the standard Mixing Length Theory (MLT). This dependence can be used to test and to constrain, through multicolor observations, the way MLT describes convection in the outermost layers of the star. We will use the equilibrium models provided by the CESAM evolutionary code. The pulsational observables are calculated by using a non-adiabatic pulsation code developed by R. Garridon and A. Moya. In the evolutionary and pulsation codes, a complete reconstruction of the non-grey atmosphere (Kurucz models) is included. The interaction between pulsation and atmosphere, as described by Dupret et al. (2002), is also included in the code. [less ▲]

Asteroseismology is one of the major important science topics in astrophysics in the coming decade. Several recent breakthroughs have indeed been made in Europe in this field. The observational data will improve significantly in the near future, as upgraded ground-based instruments are being built and two European asteroseismic space missions are planned for launch between 2005 and 2008. They will provide us for the first time with ultra-high-accuracy, high-temporal resoluton data from space for stars other than the Sun. A successful asteroseismic study involves many different steps, from state-of-the-art raw data treatment to theoretical physical modelling of the oscillation frequencies. Our network is set up to meet the needs of combining and exchanging the different expertises of the participating institutes, of training PhD students and of both training and exchanging post-doctoral researchers. This will guarantee the most fruitful and efficient exploitation of the very substantial investments that are being made in Europe in future observations of stellar oscillations, strengthening Europe's leading position in this research field. Also, it will be a test-bed for the development of efficient procedures for collaboration across the internet, involving a vast range of procedures and skills, as well as extensive common use of a broad variety of data. Furthermore, procedures will be incorporated for the joint training of students, which is an essential part of our project. [less ▲]

The coronal abundances of chromospherically active binaries have come under close scrutiny in recent years thanks to several X-ray satellites such as XMM or Chandra. Unfortunately a detailed analysis of the chemical fractionation processes that are possibly operating between the photosphere and the corona is plagued by the lack of reliable and accurate photospheric abundance determinations. In particular a detailed investigation of the photospheric metal content seems worthwhile in the light of several studies that have questioned the customary use of photometric indices as effective temperature indicators in active binaries. We shall present our ongoing effort to determine in a self-consistent way accurate physical parameters and photospheric abundances for a large number of systems and discuss the implications of our results on their abundance patterns and evolutionary status. Preliminary results suggest that these systems are not as iron-deficient as found in previous studies and indicate an overabundance of several key elements (e.g. Na Mg Al Ca) with respect to the solar pattern.

Space experiments which are aiming towards asteroseismology and the detection of exoplanets, like COROT or MOST, Eddington and Kepler, are designed to deliver high precision photometric data. Obviously, they can be used also for other purposes than the primary science goals and in addition many other targets can or will be automatically observed simultaneously with the primary targets. As a consequence, fascinating possibilities for additional (parallel, secondary) science projects emerge. For COROT a dedicated working group was thus established with the goal to contribute any useful information which may optimize the scientific output of the mission. [less ▲]
