L’étude de Feyens (2006) met en évidence une série de problèmes liés à la mise en œuvre du cours « Usages de l’ordinateur et apports des médias et des TIC en enseignement » dans le cadre de la formation de futurs enseignants (instituteurs et professeurs de l’enseignement secondaire inférieur) en Communauté française de Belgique. Par exemple, l’absence de curriculum officiel de formation, pas de titre spécifique requis chez les enseignants en charge de ce cours, … Un des axes du projet HETICE (Hautes Écoles et Technologies de l’Information et de la Communication pour l’Éducation) mené par le Centre de Recherche sur l’Instrumentation, la Formation et l’Apprentissage (CRIFA) de l’Université de Liège s’attelle actuellement à la mise au point d’un tel curriculum, à la formation des enseignants dispensant ce cours et à l’évaluation de son impact sur leurs pratiques de formation. Cet article traite d’une série d’actions entreprises pour développer ce curriculum et de leurs premiers résultats : une analyse des besoins, une contextualisation de la problématique de la formation initiale des futurs enseignants, une réflexion sur les usages et la plus-value des TIC, un sondage sur les pratiques des TIC effectives des enseignants dans leurs activités d’enseignement/apprentissage et l’élaboration d’une première mouture du curriculum tenant compte de différentes facettes et de la triple concordance entre les objectifs poursuivis, les activités d’apprentissage proposées et l’évaluation.

Several droplets, bouncing on a vertically vibrated liquid bath, can form various types of bound states, their interaction being due to the waves emitted by their bouncing. Though they associate droplets which are individually motionless, we show that these bound states are self- propelled when the droplets are of uneven size. The driving force is linked to the assymetry of the emitted surface waves. The direction of this ratchet-like displacement can be reversed, by varying the amplitude of forcing. This direction reversal occurs when the bouncing of one of the drops becomes sub-harmonic. As a generalization, a larger number of bouncing droplets form crystalline rafts which are also shown to drift or rotate when assymetrical. [less ▲]

Epithelial metaplasia (EpM) is an acquired tissue abnormality resulting from the transformation of epithelium into another tissue with a different structure and function. This adaptative process is associated with an increased frequency of (pre)cancerous lesions. We propose that EpM is involved in cancer development by altering the expression of adhesion molecules important for cell-mediated antitumor immunity. Langerhans cells (LCs) are intraepithelial dendritic cells that initiate immune responses against viral or tumor antigens on both skin and mucosal surfaces. In the present study, we showed by immunohistology that the density of CD1a LCs is reduced in EpM of the uterine cervix compared with native squamous epithelium and that the low number of LCs observed in EpM correlates with the down-regulation of cell-surface E-cadherin. We also demonstrated that transforming growth factor- 1 is not only overexpressed in metaplastic tissues but also reduces E-cadherin expression in keratinocytes in vitro by inducing the promoter activity of Slug and Snail transcription factors. Finally, we showed that in vitro-generated LCs adhere poorly to keratinocytes transfected with either Slug or Snail DNA. These data suggest that transforming growth factor- 1 indirectly reduces antigenpresenting cell density in EpM by affecting E-cadherin expression, which might explain the increased susceptibility of abnormal tissue differentiation to the development of cancer by the establishment of local immunodeficiency responsible for EpM tumorigenesis.

We consider a three dimensional (3D) finite element modeling of high temperature superconductors (HTS) submitted to a uniform magnetic field varying linearly with time. HTS are characterized by a non linear conductivity described by a power law with the critical exponent, n. We implement an A- phi weak formulation into the opensource solver GetDP. Backward Euler method is used for the temporal resolution and is coupled to a non linear Picard iteration scheme for dealing with the non linear resistivity of HTS.We consider single- and multiple-time step methods and show that the single time step method produces an accurate result in a drastically reduced calculation time for HTS with large pinning strength (or similarly, with large values of n). The finite element formulation is validated by comparing the magnetization of a HTS tube calculated either with our finite element formulation or with other well-known techniques. The numerical method is then applied for comparing the magnetization of cylinders that are drilled by different periodic arrangements of columnar holes parallel to the cylinder axis. [less ▲]
