Constat : De nombreux professeurs sont confrontés aux difficultés d’enseigner des cours dont l’intitulé et le contenu suscitent peu d’adhésion a priori de la part de certains étudiants (inintérêt personnel pour la matière donnée et non perception de la place de cet enseignement dans le programme). Objectifs : - Identifier les raisons d’un manque d’intérêt ou d’enthousiasme pour une matière ainsi que les freins à l’engagement pour son apprentissage - Prendre connaissance de différentes interventions de nature à impacter d’emblée et entretenir la perception de la valeur d’un cours - Réfléchir à la mise en oeuvre de stratégies visant à résorber ce déficit d’intérêt ou d’implication.

We investigate the nucleation of superconductivity in a superconducting Al strip under the influence of the magnetic field generated by a current-carrying Nb wire, perpendicularly oriented and located underneath the strip. The inhomogeneous magnetic field, induced by the Nb wire, produces a spatial modulation of the critical temperature Tc, leading to a controllable localization of the superconducting order parameter (OP) wavefunction. We demonstrate that close to the phase boundary Tc(Bext) the localized OP solution can be displaced reversibly by either applying an external perpendicular magnetic field Bext or by changing the amplitude of the inhomogeneous field.

An energy-based method is proposed to identify damping parameters from time histories of responses to sets of single-frequency harmonic excitation. The method is intended to be practically applicable to real structures and is able to identify the value of viscous damping, Coulomb friction and eventually other forms of non-linear damping models in aeroelastic systems. The inputs required are simply the accelerometer signals and the forces applied. It will be shown that if the system is undergoing Limit Cycle Oscillations, no external force is required for the identification process. [less ▲]

In numerous river basins, climate projections converge towards conditions leading to a significant increase in peak discharges both in terms of intensity and frequency. Therefore, managing flood risk will remain an issue of primary importance. Besides, it is currently shifting from the search for full protection against flooding towards the management of the impacts of flooding. In this respect, the elaboration of effective flood management strategies should rely on an integrated risk-based approach, encompassing not only hydraulic criteria but also economic, social and environmental factors. In addition, the considered level of detail in the analysis should be relevant given the available data and the expected outcomes. While such risk analyses have so far been mostly undertaken at a macro- or meso-scale, the herein described analysis is performed at a micro-scale, meaning that the considered assets are the individual buildings, parcels or facilities.

L'étalement de la ville est reconnu comme un enjeu social et environnemental majeur. Il convient de rappeler à cet égard que la ville actuelle est le fruit d'une longue maturation, qui prend ses germes à la révolution industrielle et qui a connu connaître une accélération spectaculaire au cours des dernières décennies. Deux questions se posent alors aujourd'hui. Sommes-nous en mesure d'engager, de manière collective, une transition vers un nouveau modèle de ville ? Quel pourrait être ce modèle de ville ? Ces deux questions sont, à notre sens, directement liées. [less ▲]

We report the discovery of three extrasolar planets that transit their moderately bright (Vmag = 12-13) host stars. WASP-44b is a 0.89-MJup planet in a 2.42-day orbit around a G8V star. WASP-45b is a 1.03-MJup planet which passes in front of the limb of its K2V host star every 3.13 days. Weak Ca H+K emission seen in the spectra of WASP-45 suggests the star is chromospherically active. WASP-46b is a 2.10-MJup planet in a 1.43-day orbit around a G6V star. Rotational modulation of the light curves of WASP-46 and weak Ca H+K emission in its spectra show the star to be photospherically and chromospherically active. We imposed circular orbits in our analyses as the radial velocity data are consistent with (near-)circular orbits, as could be expected from both empirical and tidal-theory perspectives for such short-period, Jupiter-mass planets. We discuss the impact of fitting for eccentric orbits for these type of planets when not supported by the data. The derived planetary and stellar radii depend on the fitted eccentricity and further studies use these quantities in attempts to understand planet structure, the interdependence of parameters and the relevant physics for extrasolar planets. As such, we recommend exercising caution in fitting the orbits of short period, Jupiter-mass planets with an eccentric orbital model when there is no evidence of non-circularity. [less ▲]

This work seeks to analyze the C balance of a Belgian grassland grazed by the “Blanc Bleu Belge” breed of cattle. The site is located at Dorinne in the Belgian Condroz (50° 18’ 44’’ N; 4° 58’ 07’’ E; 248 m asl.). It is permanent grassland of ca. 4.2 ha with a moderate slope of 1 to 2 %. Homogeneity and topography criteria are met to ensure high quality turbulent flux measurements. The experimental field was equipped with an eddy covariance system. Flux correction, quality control and data gap filling were performed following standardised procedures. This device was completed by a micrometeorological station that measured temperature and humidity respectively in the air and within the soil, radiation, atmospheric pressure and precipitations. Carbon exported through mowing (CNBP,export), imported through compost application (CNBP,import) or through complementary feeds for cattle (CNBP,complement) was also measured. In addition, the vegetation development was followed in order to estimate herbage production and dry matter intake by grazing animals. Carbon lost through CH4 emissions (CNBP,CH4) was finally estimated, allowing the establishment of a full C budget. After one year of measurements (May 2010 - May 2011), the grassland was a net CO2 source (Net Ecosystem Exchange (NEE) = 172 ± 94 g C m-2 year-1). Net Biome Productivity (NBP) was calculated from NEE by taking into account imports and export of organic C and losses of carbon as CH4. Contribution of CNBP,CH4 to NBP was small as it was 12 ± 1 g C m-2 year-1. The balance between CNBP,import and CNBP,export created not such a large departure of NBP from NEE, which is not the case of CNBP,complement. The NBP was finally estimated at 102 ± 95 g C m-2 year-1. At this stage, it is premature to conclude about the sink or source behaviour of the plot because the NBP value is very close to its uncertainty. Moreover, this result was obtained under particular climate conditions, characterised by drought during summer 2010 and spring 2011. First year full carbon budget will be discussed in relation with climate conditions and management practices. A second year of measurements will be also presented. [less ▲]
