As part of our continuing research for anticancer compounds from the Walloon Region forest, EtOAc extract from Carpinus betulus leaves was phytochemically studied, leading to the bioguided isolation of pheophorbide a, which is responsible of anticancer properties of C. betulus young leaves. This compound was identified using nuclear magnetic resonance and mass spectrophotometric data and comparison with a commercial standard. Evaluation of the growth inhibitory activities of pheophorbide a using MTT colorimetric assay and phase-contrast microscopy in various human cancer cell lines confirmed the photoactivable properties of this compound. Our research showed, for the first time, the presence of pheophorbide a, a chlorophyll derived compound, which we quantified in high quantities in young leaves of C. betulus. This is in contrast with the literature which generally describes pheophorbide a as a catabolic product of chlorophyll, then preferentially present in old leaves. [less ▲]

Using first-principles calculations, we investigate the electronic, structural, and vibrational properties of SrZrO3. We start from the high-symmetry cubic perovskite phase, for which the phonon dispersion curves are reported.We point out the coexistence of structural antiferrodistortive instabilities at the R and M zone-boundary points and a ferroelectric instability at the zone center.We showthat the strong antiferrodistortive motions suppress ferroelectricity and are responsible for the orthorhombic ground state as in CaTiO3. The structural properties <br />of possible intermediate phases and of the orthorhombic Pnma ground state are reported. For the latter, an assignment of IR and Raman zone-center phonon modes is proposed. The main features of the ferroelectric instability are also discussed, and we show that a ferroelectric ground state can even be induced in SrZrO3 by strain engineering. [less ▲]

Pseudomonas fluorescens is commonly used as bio-fungicides in agriculture. For this use it requires formulations as either liquid or powder. Formulations have two advantages, storage and transport. Freeze-drying is a commonly used method to preserve bacteria. However, freeze-drying damages the cells, which results in loss of viability. Protective compounds are used to reduce loss of viability during process (freeze-drying and storage). In our study we used flow cytometry analysis to assess the physiological state in which cells are at the end of freeze-drying and Glutathione (GSH) was measured before and during storage. [less ▲]

The present advances in hydro-mechanical analysis of a clayey rock fracturing are presented at a department seminar. The damaged zone existing around galleries composing underground structures is studied through two aspects: rock-atmosphere interaction at gallery wall and rock fracturing modelling. These two aspects are discussed through the numerical results of an in situ ventilation test modelling and a biaxial compression test modelling. [less ▲]

As part of the ICE2SEA project, the regional climate model MAR was forced by the global models HadCM3 and ECHAM5 for making future projections of the Greenland Ice Sheet (GrIS) Surface Mass Balance (SMB) over 1980-2099 at a resolution of 25km. However, the comparison with MAR forced by the ERA-40 reanalysis over 1980-1999 shows that MAR forced by these GCMs is not able to represent reliably the current SMB due to biases in the general circulation and in the free atmosphere summer temperature modelled by these GCMs around the GrIS. <br /> <br /> That is why, we present here first results of MAR forced by the next generation of GCMs from the CMIP5 data base (CanESM2 and NorESM1 here). The comparison with the ERA-40 forced MAR simulations over current climate is a lot of better, which increases the reliability and the interest of these new MAR projections. In addition, the new scenarios (RCP 2.6, 4.5, 6.0 and 8.5) of the next IPCC Assessment Report (AR5) are used here. These new simulations show notably that the response of SMB to rising temperature is not a linear function of the temperature anomalies due to the positive albedo feedback which accelerates the surface melt. For 2100, in case of extreme rising temperature (RCP 8.5 scenario), MAR simulates a surface GrIS mass loss corresponding to a cumulated sea level rise of about 15 cm since 2000! Mainly the changes in SMB and in surface energy balance will be discussed here. [less ▲]

La mémoire du génocide des Juifs est encore vivace dans nos sociétés contemporaines. Ce fait passé apparaît fréquemment dans l’actualité au rythme des commémorations régulièrement organisées. Mais que peut-il signifier aujourd’hui pour de jeunes générations qui en prennent connaissance à l’école, en famille, par la visite de lieux de mémoire ou encore par de multiples œuvres cinématographiques ? Les impacts de ces connaissances sont ainsi très peu étudiés, notamment en termes d’apprentissage d’attitudes et de comportements politiques chez des jeunes amenés à devenir les citoyens de demain. En s’inscrivant dans le champ de la socialisation politique, l’objectif de cette étude est justement d’analyser les conséquences de ces connaissances. Pour ce faire, de jeunes Belges francophones ont été rencontrés dans le cadre de groupes de discussion. L’analyse des échanges montre que ces jeunes ont tenu différentes expressions sociales et politiques à partir de discussions portant uniquement sur le génocide des Juifs. En soulignant l’importance du souvenir, en témoignant de multiples émotions et en mobilisant toute une série de valeurs, ils ont envisagé la transmission de ce fait passé. Par ailleurs, leurs connaissances et leurs perceptions de l’univers politique ainsi que la façon dont ils envisagent leur participation politique interrogent leur rapport au pouvoir politique. En explorant l’univers mental des jeunes à partir de la thématique du génocide des Juifs, leur prise de conscience des cheminements politiques conduisant à un tel fait est mise en perspective. C’est aussi l’éventualité de sa répétition ou encore l’effacement de sa mémoire dans la dynamique des générations qui est mis en questions et en débats. [less ▲]
