The paper presents some applications of a local second gradient theory used to describe the mechanical behavior of a continua. This theory has been developed in order to avoid some well known drawbacks of classical theories, when softening and/or localization occur in a computation. This theory is extended and then applied in a hydromechanical coupled problem, in the case of fully saturated geomaterials. The corresponding finite element method taking into account the geometrical non linearities is detailed. Preliminary results using the finite element code developed in this context are then discussed and allow to study post localization behavior. [less ▲]

This paper describes the main concepts of the stress-strain interpolation model that has been implemented in the non-linear finite element code Lagamine. This model consists in a local description of the yield locus based on the texture of the material through the full constraints Taylor’s model. The prediction of the Swift effect is investigated: the influence of the texture evolution is shown up. The LAMEL model is also investigated for the Swift effect prediction. [less ▲]

Two competitive design studies for the Ground-based European Nulling Interferometer Experiment (GENIE) have recently been initiated by the European Space Agency and the European Southern Observatory. A major issue in these studies is the influence of atmospheric turbulence on the performance of the instrument, and how atmospheric effects can be compensated in order to reach the goal performance (detection of faint exozodiacal clouds). In this paper, we review the main atmospheric processes affecting a nulling interferometer and discuss possible ways to reduce them by means of real-time control systems. Preliminary performance estimates of GENIE are then presented. The effects of the thermal background and its fluctuations (Absil & Bakker 2004) are not considered here. [less ▲]

L'exploitation des nouvelles technologies dans la mise sur pied d'un enseignement à distance s'accompagne nécessairement d'une réflexion pédagogique structurée. Cette réflexion fait souvent fi de la mise en oeuvre de véritables stratégies motivationnelles. Pourtant, lorsqu'on demande à un enseignant pourquoi il souhaite mettre un cours en ligne, il invoque souvent le fait de chercher à motiver ses étudiants. Nous distinguerons ici le maintien de la motivation, du renforcement de la motivation des étudiants. Les risques de démotivation et d'abandon sont très nombreux dans l'enseignement à distance, même avec le soutien des nouvelles technologies. Il est donc essentiel de veiller à maintenir constamment la motivation initiale de l'apprenant. Si le maintien de cette motivation fait appel à des moyens, des trucs, des recettes de tutorat, il n'en va pas de même du renforcement de la motivation. En effet, il s'agit ici de mettre au point, dès la phase de conception du cours, de véritables stratégies motivationnelles. Quels sont les risques de démotivation des étudiants ? Comment les éviter ? Quelles bases théoriques peuvent nous guider dans notre mise au point des stratégies motivationnelles ? Quelles pistes motivationnelles le concepteur peut-il emprunter, et dans quelles perspectives ? Sur base des théories de la motivation, notre recension des données bibliographiques vise à préciser les questions que doivent se poser les concepteurs de cours à distance. De même, elle débouche, pour chaque question, sur des pistes concrètes à explorer. [less ▲]

Students’ motivation is a major concern of physical education teachers as well as it interest the others educators. Understanding of that complex variable increased during the last two decades. In the physical education domain, many studies were focused on isolated variables related to motivation and on their relationship with pupils’ behaviours. More recently, qualitative researches were conducted to enter in the class specificity and to integrate the complexity and diversity of the variables that influence students’ motivations. Combining questionnaires interviews and observation, some researchers have confirmed that student’s motivation depends on a package of dispositional as well as individual and collective situational factors. They pointed out also the determining role of the teacher in the development of a motivated class climate. This paper will describe a couple of qualitative studies designed to analyse students’ motivation and will underline their contribution in the understanding of the phenomena related to the development of motivation by students. Moreover, as teachers need research directly focused to their concerns, we must now provide them more support helping them to apply research data. The action research design is proposed as an appropriate approach in that way. The description of a pilot action research focused on the improvement of the students’ motivation in a secondary school level girls class will also proposed. The main results should provide the starting point of a reflective process about the strategies that teachers could plan on the gym. As it has been underlined above, the goal of the paper was to share useful information with practitioners and researchers and to encourage them to involve themselves in personal research on students’ motivation.

This paper models the sea bottom evolution. This model is built up on three main parts. The first one describes the wave propagation, taking simultaneously into account the refraction, the diffraction and the reflection but also the energy dissipation caused by wave breaking. This model is solved by the numerical method of the finite volumes, using an iterative resolution (the GMRES method). Several validations of this model have been carried out on many examples such as harbors of various geometries and depths, beaches,… The wave induced currents are computed in the second part based on the concept of the radiation stresses describing the excess of the flux momentum caused by the waves. A model based on the complete Navier-Stokes equations integrated on the depth and associated with appropriated forcing and friction terms is used. This model is computed as an update of WOLF software (HACH, ULg) and is applied to some examples such as beaches with or without coastal structures. Finally, the third part is about the sediment transport. It exhibits the topographic modifications of the coastal sea bottom caused by the waves and their currents. A loop execution of these three models ends this work. It gives us an operational tool to describe the topographic evolution of the coastal areas caused by the incident waves, the induced currents and then the resulting sediment transport, fulfilling the objectives of this paper.

L’objectif de ce travail est d’étudier, dans les conditions réelles de production, la variabilité de la qualité technologique, organoleptique et microbiologique de la viande de porc et d’objectiver les relations qui peuvent exister entre les variables évaluées. L’analyse en composantes principales a permis de mettre en évidence des groupes de variables et de visualiser les relations qui peuvent exister entre ces variables. La première composante principale est corrélée aux variables relatives à la qualité technologique et organoleptique de la viande. Elle met en opposition le pH45 d’une part et les paramètres L*, b* et Cond45 d’autre part. La deuxième composante principale peut être considérée comme un axe de qualité microbiologique.

The significance of a Salmonella serological technique has been evaluated in 91 batches from 9 pigs fattening herds. Samples for bacteriology (method based on motility of Salmonella in semi-solid medium) were taken at different steps during fattening: 2, 3 and 4 months after the beginning of the fattening period. The serological test (Salmotype Pig-LPSElisa) has been applied on meat juice obtained after thawing of diaphragm meat cuts taken on the slaughter line. The performances of the serological method were evaluated by choosing microbiological method as reference. Correlations were practiced by comparing results of optical densities of samples with cut-off values corresponding to 4 different antibody concentrations. Forty-eight different possibilities have thus been created depending on the percentage of positive samples above the cut-off value and in function of arithmetic and geometric means. The results have shown that negative predictive values ranged from 52.8 and 100 % and that the relative sensitivity varied between 4.5 and 100 %. One classification model appeared better than the others due to maximization of Kappa, negative predictive and relative sensitivity values: batch considered positive when at least 50 % of samples were characterized by an optical density higher than OD20% (optical density corresponding to an antibody concentration of 20 %). The present experiment showed the importance of good classification of individual serological results in order to strengthen the on-farm bacteriological surveillance of herds. [less ▲]

Near Earth Object 2003 EH_1, first seen by LONEOS on 2003 March 6, was identified in early December as the parent of the Quadrantid shower based on the orbit calculated from 48 days of observations following its discovery [1]. The Quadrantids is our most intense annual shower and was until now the only major shower with no parent body. The orbit matches the inclination, semi-major axis, and argument of perihelion of the Quadrantid meteoroids, but has a perihelion distance outside of Earth orbit. It was shown that frequent close encounters with Jupiter result in a rapid dispersion of perihelion distances, accounting for the current orbit of the parent body. The dispersion of orbits in the meteor shower implies a young ˜ 500 year age and the large mass in the stream suggests formation during a comet breakup. This leaves open the possibility that comet C/1490 Y1 was a sighting of the object shortly after it broke up near aphelion, but to match the perihelion time with that of the backward integrated orbit of 2003 EH_1, a better orbit solution is needed. In December and January of 2003, we recovered the object with the ESO New Technology Telescope and computed a much improved orbit. We used that new orbit to study the formation of the Quadrantid stream for various epochs of ejection. In the context of evaluating the NEO impact hazard, those meteoroids trace the orbital evolution of other possible fragments from the breakup 500 years ago that may now be on a collision course with Earth.

In the global framework of safety, the study of the hydraulic consequences of a dam breaking, sudden and instantaneous for concrete structures, gradual for earth ones, is of major interest in the scope of prevention policies or protection plans for populations and goods. Suitable numerical models, coupled with contemporary computational possibilities, allow engineers to forecast these complex situations with a great reliability. In this field, WOLF 2D is an efficient analysis and optimisation tool, which has been completely developed by the Applied Hydrodynamics and Hydraulic Constructions team (HACH – http://www.ulg.ac.be/hach) of the University of Liege. It is part of WOLF free surface flows computation package, which includes in the same development environment the resolutions of the 1D Saint-Venant equations, the 2D shallow-water equations as well as a physically based hydrological model and powerful optimisation capabilities based on Genetic Algorithms. The interactive and unique user-interface, with high performance pre- and post-processing, allows monitoring 3-D large-scale runs graphically while they proceed, as well as generation of 3D videos. Each code handles general multiblock meshes, dealing with natural topography and mobile bed simultaneously, for any unsteady situation with mixed regimes and moving hydraulic jumps. By this way, WOLF deals with all free surface hydraulic phenomena, from hydrological runoff and river propagation to extreme erosive flows on realistic mobile topography, such as gradual dam breaching processes. It has moreover proved its efficiency and reliability for years by numerous real applications. The first part of this paper covers a brief description of the 2D multiblock flow solver WOLF 2D and the underlying mathematical model. The second part depicts the application of WOLF computation capabilities to the well-known Malpasset dam break (France, 1959), which induced a catastrophic almost instantaneous release of 48 millions m³ of water in the Reyran river valley down to the town of Frejus and the Mediterranean sea. Data available thanks to the CADAM EU-project are used to assess the results. [less ▲]

Radiometric dates, typology and sedimentology suggest an autochthonous origin for the Gravettian culture in the Middle Danube. Its complex development is marked by tool specialisation, a demographic increase and an apparent sedentism. Subsequently, this key region spread to the east or the west by autonomous migratory movements during each phase (Bayacian, Kostenkian). The form of religiosity that is finally associated with this culture constitutes the first artistic creation evidencing a matriarchal system. Through the artistic forms, this belief system is also modified through time and across space: it is characterised as well by recognisable artistic “styles”. The broad Gravettian entity, in its distribution and the finesse of its adaptation, was a product of continental Europe, for which it constitutes the origin of later cultures and populations. At the same time, its plastic expressions seem to result in an Aurignacian acculturation, and its anatomy a blend of Neandertals with incoming modern humans. Curiously, recent phases are limited to the eastern Danube Basin. The Pleniglacial B seems to have interrupted western contacts, where the Magdalenians would soon appear, until Moravia. From then on, Europe as a whole would no longer be unified. In consequence, new approaches to the study of the Danubian Gravettian should be oriented towards the eastern plains, Moldavia and The Crimea. [less ▲]
