The morphology of Jupiter’s ultraviolet aurora is commonly described in terms of components located inside (poleward of) or outside (equatorward of) the main oval emission. These components may also be discriminated by their temporal behaviour, where the narrowest parts of the main “oval” remain relatively stable over time periods of several hours, and the satellite footprints show large variability with timescales of minutes. Inside the main emission the so-called polar aurora, presumably corresponding to the polar cap mixing open and closed magnetic field lines, is characterized by rapid motions taking the form of swirls, giving rise to the “swirl region” and by intermittent brightenings in the “active region”. Coarse analysis of these motions suggests that they are too fast to respond to an equatorial magnetospheric forcing. Instead, they appear to be related to processes taking place in or above the ionosphere where distances travelled by plasma waves match those of the subtended auroral emission. Here, we present a preliminary improved analysis of the auroral motion in the polar region based on the application of an iterative “Advection Corrected Correlation Image Velocimetry” (ACCIV) method (Asay-Davis et al., 2009). This method allows one to build velocity fields quantifying local and overall auroral motions which may then be used to constrain their origin. [less ▲]

La réforme des études de médecine introduite en 2012 en Communauté Française (Belgique) a fortement modifié les programmes de cours, entre autres celui de physique, pour lequel certaines notions sont désormais considérées comme prérequises. Conscientes que celles-ci ne sont pas toujours acquises par les étudiants, les équipes pédagogiques de l'ULg ont élaboré des systèmes de remédiation. Un espace en ligne a notamment été développé, parallèlement au cours présentiel, afin de permettre aux enseignants et aux étudiants d'évaluer les difficultés et lacunes de ces derniers et d’y remédier. Cet outil est conçu pour offrir une aide spécifique adaptée à chacun malgré le nombre important d’étudiants inscrits (800 en 2013). Ils peuvent y travailler, de manière progressive et autonome, les aspects théoriques (notes et tests formatifs) et pratiques (exercices, problèmes décomposés ou non). Des tests diagnostiques en début et fin de parcours permettent aux apprenants d’apprécier leur évolution. De plus, la plate-forme centralise différents outils interactifs (forums, calendrier, annonces, …) accompagnant l’étudiant dans l’organisation de son parcours. Les premières analyses de traces indiquent une corrélation entre travail en ligne et réussite. Une adaptation progressive de l’outil sera basée sur l’analyse des résultats et du ressenti de étudiants. [less ▲]

Spinal cord injury (SCI) treatment represents a critical issue in clinical research and patient care. Stem cell-based replacement therapies have already been proposed worldwide, especially studying stem cells from the adult bone marrow stroma. Previous studies focusing on those cells did not specifically consider their intrinsic embryonic heterogeneity, thus intermingling different stem cells subpopulations to treat experimental SCI or even injured patients. In this study, we decided to compare adult bone marrow neural crest-derived stem cells (NCSC) and mesenchymal stem cells (MSC), and highlight which of their specific properties could be relevant in therapeutic perspectives. In that purpose, we compared NCSC and MSC isolated from adult mouse bone marrow. We then compared the effects that both cell types could exert once grafted inside an injured spinal cord. Cells were injected into the spinal cord of mice that right after a spinal cord contusion at the T11-12 spinal level. Our results indicate that both MSC and NCSC-injected mice recovered locomotion abilities faster than control mice (as assessed by BMS scoring). Additionally, we observed that after 28 days post-injury, the lesion volume tended to decrease in mice that received cell graft compared to control group. Interestingly, it appeared that MSC seemed to be able to modulate inflammation inside the lesion, more than NCSC. Indeed, MSC-graft increased early neutrophil and macrophage recruitment in the bloodstream and inside the spinal cord, and increased the number of arginase-1-expressing cells remaining in the spinal cord after 28 days. In parallel, we compared the secretome of both NCSC and MSC, and noticed some interesting differences: MSC secreted several chemokines reflecting possible immunomodulating properties, while NCSC secreted products might be able to enhance neurite outgrowth. Indeed, preliminary data showed that NCSC induced neuritogenesis on primary neurons in vitro. Altogether, those results should help to improve and optimize cell-based therapies parameters and/or to define precise and efficient pharmacological treatments for SCI patients. [less ▲]

This powerpoint presentation was used as teaching material in a seminar given as part of the course “Compléments de fabrication mécanique et FAO” at Université catholique de Louvain. It outlines important current issues in the developments of additive technologies for the processing of metallic materials by discussing two case studies from researches carried out by the Metallic Materials Science Unit (ULg). In particular, two different metallic alloys, i.e. stainless steel 316L and Ti-6Al-4V, have been processed by laser beam melting under similar conditions, and their microstructures and mechanical behaviours have been compared in details. Under the investigated conditions, Ti-6Al-4V exhibits a more complex behaviour than stainless steel 316L with respect to the occurrence of microstructural and mechanical anisotropy. Moreover, Ti-6Al-4V appears more sensitive to the build-up of internal stresses when compared with stainless steel 316L, whereas stainless steel 316L appears more prone to the formation of “lack of melting” defects. This correlates nicely with the difference in thermal conductivity between the two materials. Thermal conductivity was also shown to increase strongly with increasing temperature. [less ▲]
