This paper presents a multi-scale framework for the failure of periodic quasi-brittle thin planar shells. The failure behavior of textured or periodic heterogeneous materials is strongly influenced by their mesostructure. Their periodicity and the quasi-brittle nature of their constituents result in complex behaviors such as damage-induced anisotropy properties with localization of damage, which are difficult to model by means of macroscopic closed-form constitutive laws. A computational homogenization procedure is used for the in-plane and out-of-plane behavior of such planar shells, and is combined with an acoustic tensor-based failure detection adapted to shell kinematics to detect the structural-scale failure. Based on an assumption of single period failure, the localization of damage at the structural scale is represented by means of mesostructurally informed embedded strong discontinuities incorporated in the macroscopic shell description. A new enhanced scale transition is outlined for shell failure, based on an approximate energy consistency argument to objectively upscale the energy dissipation. The corresponding multi-scale framework results are compared with direct fine-scale modeling results used as a reference for the case of masonry, showing good agreement in terms of the load-bearing capacity, of failure mechanisms and of associated energy dissipation. © 2010 John Wiley & Sons, Ltd.

OBJECTIVE: Telomeres are protected by tightly regulated factors and elongated by telomerase. Short and/or deprotected chromosomes are recombinogenic and thereby cancer prone. MATERIALS AND METHODS: Together with the quantification of telomerase activity (TA), measuring telomere length (TL) and expression of the genes that govern telomere protection and elongation are useful for assessing telomere homeostasis. RESULTS: By these means we demonstrate that TL, hTERT, and TA are in the order acute myelogenous leukemia (AML) > T-cell acute lymphoblastic leukemia (T-ALL) > B-cell acute lymphoblastic leukemia (B-ALL) > T-ALL > AML, and B-ALL > AML > T-ALL. AML0 and AML3 display the lowest amounts of hTERT transcripts, and ALL and AML cells with cytogenetic abnormalities possess the shortest telomeres. hTERT expression includes phenotype-specific RNA maturation and correlates with TA but not with TL. A wide ratio of TA to hTERT expression between leukemia subtypes suggests phenotype-specific hTERT post-transcriptional deregulations. B- and T-ALL overexpress Ku70 and Pinx1, T-ALL PTOP and RAP1, and B-ALL TRF2, the expression of which is significantly higher in cases with abnormal karyotype. hTERT transcription and TL correlate with response to intensive chemotherapy, and hTERT and RAD50 are independent prognostic factors for survival. CONCLUSIONS: Each leukemia subtype possesses specific telomere dysregulations that rely on phenotype, karyotype, response to treatment, and survival. [less ▲]

Environmental and agronomic issues require always more well thought and suited farmer management of agricultural inputs; soil analysis is therefore an essential tool to support decision. However, for a soil analysis to provide valuable information, it is essential for the sample to be representative of the studied field. Without this representativeness, an analytical result, as accurate as it could be, would not be of interest if it could mislead the farmer. In practice, the main difficulty for the sampler is the recognition of soil criteria which are essential to provide a fertility advice, especially in Wallonia (Belgium) where soil variability is very important. With the Digital Soil Map of Wallonia (DSMW), drowned at the scale 1/5,000, it seems appropriate to give these information to the samplers in an useful form for routine works. That is why a mapping tool for decision support, named REQUACARTO, was designed to be used for soil analysis by provincial laboratories, members of the REQUASUD laboratories network. This tool responds to a real requirement in Wallonia: achieving a quality sampling for the development of personalized soil fertility advice. [less ▲]

Quantum cavities or dots have markedly different properties depending on whether their classical counterparts are chaotic or not. Connecting a superconductor to such a cavity leads to notable proximity effects, particularly the appearance, predicted by random matrix theory, of a hard gap in the excitation spectrum of quantum chaotic systems. Andreev billiards are interesting examples of such structures built with superconductors connected to a ballistic normal metal billiard since each time an electron hits the superconducting part it is retroreflected as a hole (and vice versa). Using a semiclassical framework for systems with chaotic dynamics, we show how this reflection, along with the interference due to subtle correlations between the classical paths of electrons and holes inside the system, is ultimately responsible for the gap formation. The treatment can be extended to include the effects of a symmetry-breaking magnetic field in the normal part of the billiard or an Andreev billiard connected to two phase-shifted superconductors. Therefore, we are able to see how these effects can remold and eventually suppress the gap. Furthermore, the semiclassical framework is able to cover the effect of a finite Ehrenfest time, which also causes the gap to shrink. However, for intermediate values this leads to the appearance of a second hard gap-a clear signature of the Ehrenfest time. [less ▲]

Le cours de Médecine Palliative est organisé en avant-dernière année des études médicales de 2e cycle par deux enseignants, Médecin Généraliste et Médecin Hospitalier. Ce cours a été dispensé pendant 10 ans selon un format traditionnel ex cathedra. Il était dispensé par de nombreux intervenants pluridisciplinaires. Une évaluation des enseignements a montré que les étudiants jugeaient les interventions trop théoriques, sans lien avec leurs questions et préoccupations. En conséquence, c’est la discipline « Médecine Palliative et de Soins de Vie » qui ne suscitaient pas d’intérêt. De nouveaux objectifs et de nouvelles modalités pédagogiques ont été introduits en 2010-2011 à l’attention de 100 étudiants. L’objectif principal est le développement chez les étudiants d’une attitude réflexive face à la discipline « Médecine Palliative ». Les outils pédagogiques introduits dans le dispositif sont le portfolio électronique, une vignette clinique évolutive, l’accompagnement à distance de chaque étudiant par un tuteur, des cours en présentiel. La pratique réflexive de chaque étudiant est évaluée au terme du dispositif, conjointement par les 2 enseignants sur base de critères et d’indicateurs. Voici une illustration des critères utilisés : - Intensité des interactions dans le carnet d’apprentissage électronique (et aux cours) - Pertinence des interventions - Engagement dans la tâche - Capacité réflexive (pertinence de l’analyse et de la régulation de la situation décrite dans la vignette) - Qualité de l’auto-évaluation et identification des éléments déclencheurs de progrès - Degré d’apprentissage (Bilan d’atteinte des objectifs fixés par le cours et décrits) La communication orale présentera le dispositif d’évaluation, les critères et les indicateurs utilisés, les premiers résultats de l’évaluation des étudiants, les perspectives de régulation du dispositif d’évaluation.

Thin films of FeSb3 were characterized by electronic transport magnetometry, x-ray diffraction, Fe-57 and Sb-121 nuclear inelastic scattering, and Fe-57 Mossbauer spectroscopy. Resistivity and magnetometry measurements reveal semiconducting behavior with a 16.3(4) meV band gap and an effective paramagnetic moment of 0.57(6) mu(B) respectively. A systematic comparison of the lattice dynamics with CoSb3 and EuFe4Sb12 reveals that the Fe4Sb12 framework is softer than the Co4Sb12 framework, and that the observed softening and the associated lowering of the lattice thermal conductivity in the RFe4Sb12 filled skutterudites are not only related to the filler but also to the Fe4Sb12 framework.
