Trace elements (TEs) remain contaminants of concern because of their persistence, ability to concentrate in organisms and toxicity. The Mediterranean mussel Mytilus galloprovincialis Lamarck, 1819 is a relevant bioindicator of TE coastal contamination. However, little research has studied the combined influence of environmental condition changes and physiological processes on their kinetics in that species. Caged M. galloprovincialis were thus immerged in 2 contrasted pristine Corsican (France) coastal environments, the semi-enclosed Diane salty pond and the open Calvi Bay, from February to June 2011. Mussels were regularly sampled to study the kinetics of 19 TEs in their flesh; dissolved and particulate TEs were also monitored. The primary production and the water physico-chemical variables were measured, and meteorological data were purchased from Météo-France. TE kinetics in mussels differed between sites. Mussel spawning, a temperature and saline-induced physiological process that occurred about 10 days later in the Diane pond, was followed by a short time increase of TE levels in the mussel flesh. Mussel contamination also evolved according to changes of their respective environmental TE levels. Raining events temporary led, in the Diane pond, to the water enrichment with TEs, nutrients and detrital material, to peaks of primary production and to the increase of TE concentrations in the mussel flesh. This step by step evolution of TE levels in the environment and mussels was afterwards followed by a rapid return to initial conditions. In the open Calvi Bay, these fast and balanced kinetics were not so obvious, because of the rapid dilution of environmental constrain effects in the Bay. Mussels are often used as bioindicator in estuaries and coastal enclosed meadows with rapidly changing environmental conditions. In such conditions, the influence of the environment on TE kinetics in mussels must be considered, in addition to physiological processes, when monitoring the TE coastal contamination. [less ▲]

Nowadays, the knowledge of the marine ecological quality status of an environment is essential and soft-bottom macrobenthos is one of the indicators used. Studies of soft-bottom macrobenthos are time consuming and need expertise for organisms’ identification. Simplifications of these studies are tried and Taxonomic Sufficiency (TS) proposed by Ellis (1985) is one of research axes. For example, some studies highlight that family level identification could be sufficient to identify perturbed area (e.g: Bacci et al., 2009; De-La-Ossa-Carretero et al., 2012; Forde et al., 2013). Nevertheless, identification at species level could be recommended to have more precise information about the existing situation (Ajmal Khan, 2006) or to complete information from others levels (Conde et al., 2013). In Corsican waters where human impacts are less important than in main land waters, we present TS based on STARESO research studies between 2006 and 2012. This work is within the frameworks of the STARE-CAPMED program dedicated to STAtion of Reference and rEsearch on Change of local and global Anthropogenic Pressures on Mediterranean Ecosystem Drifts. After Permanova analysis and Canonical analysis of principal coordinates, eight habitat types have been identified along Corsican coastal water. Their own reference conditions and ecological class boundaries have been evaluated. Those reference conditions and ecological status have been identified for species, genus and family level. A highly significant correlation of calculated values between species and genus levels (R²=0.93) has been determined and a significant correlation between species and family level (R²=0.75). Genus and family levels have a significant Spearman correlation with species level (p<0.05). An application of these reference conditions on the macrobenthos assemblages sampling on 14 stations in spring 2011 and late summer 2012 in Calvi Bay highlights areas with high, good or moderate ecological status. In conclusion, family level is sufficient to follow spatial and/or temporal ecological status. [less ▲]

The Pyrenean desman (Galemys pyrenaicus) is a small semi-aquatic mammal endemic to the Pyrenean Mountains and the northern half of the Iberian Peninsula where it lives in mountain streams of cold and well-oxygenated flowing waters (Nores et al. 2007). This species is currently considered as vulnerable in the IUCN Red List (Fernandes et al. 2008) and has been suffering from habitat loss and fragmentation for decades, inevitably impacting its distribution. The ecology and biology of this species are poorly known, notably because of its elusive behavior and its primarily nocturnal activity (Stone 1987, Bertrand 1994). Its distribution area is even not definitively established. Furthermore, a recent genetic study, based on mitochondrial and intronic sequences (Igea et al. 2013), showed that the genetic variability of the Pyrenean desman is very low in the Pyrenees. In this study we investigated the potential existence of a genetic structure and gene flow at a smaller scale using 24 polymorphic microsatellites loci. As the Pyrenean desman is a very elusive species, we completed our sample collection of tissues with faeces samples coming from the French distribution area of this species. Doing so, we successfully identify 70 individuals out of 355 faeces samples. Bayesian analyses revealed a cryptic genetic structure in our data set. Three clusters were evidenced (one western, one central and one eastern) and gene flow appears to be limited between these clusters (min. Fst value of 0.2). [less ▲]

Many applications require the use of multiple cameras to cover a larger volume. In this paper, we evaluate several pair-wise calibration techniques dedicated to range cameras. We compare the precision of a self-calibration technique based on the movement in front of the cameras to object based calibration. While the self-calibration method is less precise than its counterparts, it yields a first estimation of the transformation between the cameras and permits to detect when the cameras become mis-aligned. Therefore it is useful in a practical situations. [less ▲]

Ductile damage is a physical phenomena which involves progressive deterioration of mechanical properties of metals, when undergoing high deformations. Compared to plasticity, the physical mechanisms behind damage are more complex and the microscale is not longer negligible. In mathematical damage models, founding an optimal set of material parameters can be a hard task due to the strong coupling and non-linearity of the equations. An identification strategy is then crucial to arrive to a general set of parameters. Therefore, we address the fully characterization of a ferritic steel sheet, involving the elasto-plastic and damage parameters. This poster presents an hybrid experimental-numerical procedure, coupling numerical simulations, optimization algorithms and digital image correlation measurements, over a set of representative experimental and numerical results of tensile, shear and plane strain tests in different material directions. Due to the small thickness of the sheet, the constitutive model is very prone to localization into a shear band difficulting the damage parameters identification. It is found that a porosity induced inhomogeneity plus a mixed hardening can delay localization and represent the entire deformation range of the tests, leading to acceptable results. Different set of parameters are also obtained and then validated with experimental results. This localization phenomena should be carefully considered in applications involving complex strain paths.

There is literature aplenty concerning the rescue of Jewish children in Belgium during the Second World War. However, it appears that some questions have remained unanswered to his day about the consequences and the memory processes of these rescues by the Catholic clergy of Liege. After a brief overview of said rescue activities (1942-1944), this contribution will broach, supported by hitherto unexplored archives, three issues: 1. what are the consecutives stages of the memory process from 1944 to 2010? 2. How was this recognition expressed and what were its manifestations or why did it fail to occur? 3. Who are the protagonists –Christians, Jews, Israelis- of this process and what are their interests?

The protection of historical concrete structures is a challenge for the coming years. Hydrophobic treatment may reduce the deterioration process while providing protection against water penetration. Existing commercial products —mainly silane or siloxane in either water or solvent based formulations– were submitted to different ageing processes including UV radiation, dry-wet cycles, thermal shocks, freeze-thaw cycles, carbonation and their effectiveness has been evaluated on the basis of contact angle, vapour and chloride permeability and, capillarity water absorption. The results obtained clearly show that hydrophobic treatments display a good behaviour under the main ageing conditions. [less ▲]

A la fin de "Baader", le seul biopic à être entièrement dédié au fondateur de la Fraction Armée Rouge, le réalisateur Christopher Roth prend certaines libertés explicites avec l’histoire de la RAF pour proposer une singulière relecture de l’arrestation du personnage titre : pris au piège comme ce fut effectivement le cas en juin 1972 dans un garage francfortois qui lui servait de planque d’armes et d’explosifs, et que le film prend soin de reproduire fidèlement, Baader n’est pas arrêté par la police . Il fait d’abord mine de se rendre, avant de saisir deux pistolets pour tirer sur les agents qui l’encerclent. Se trouvant complètement à découvert, le terroriste est immédiatement criblé de balles et s’effondre. Le président de la police judiciaire Herold alias Krone accourt, le regard empli de tristesse et d’effroi. Il prend le corps sans vie de Baader dans ses bras, tient son visage vers le ciel, et transforme ce tableau final en une Pietà . Notre texte montre d'abord que, sur fond de rapports « tendus » entre années de plomb allemandes et historiographie, cet écart par rapport aux faits avérés est pour le moins remarquable car, exception faite du film de Roth, tous les films biographiques consacrés aux cadres de la RAF se caractérisent par leur constance et leur uniformité dans la construction du personnage d’Andreas Baader. Cet article identifie en outre quelques-uns des effets politiques et historiographiques de cette invariabilité, en s’intéressant notamment aux personnages des deux principales camarades de lutte du terroriste, Ulrike Meinhof et Gudrun Ensslin. L’ensemble des éléments dégagés tout au long d'une déambulation parmi quelques fictions nous permet enfin de mesurer la portée critique du "showdown" imaginé par Christopher Roth. [less ▲]

Faisant suite à une première phase (2006-2008), le projet pilote Développement d’Alternatives Communautaires à l’Exploitation Forestière Illégale (DACEFI-2, de 2010 à 2014) s’est employé à tester au Gabon la mise en oeuvre des forêts communautaires, promues par le code forestier gabonais en 2001 (loi n°016/01). Pour cela, le projet a appuyé les communautés rurales désireuses de gérer elles-mêmes une portion de forêt et les a accompagnées tout au long du processus de création d’une forêt communautaire. Ce processus, adapté dans la mesure du possible aux communautés rurales, est jalonné de multiples étapes et peut paraitre parfois long et fastidieux. Présentant des méthodologies d’action et des cartes, cet atlas a été développé à la fin des 5 années d’exécution dans l’idée de capitaliser la démarche adoptée par le projet pour aboutir à la délimitation d’une forêt communautaire. Il vient également synthétiser pour le lecteur les travaux cartographiques réalisés dans les villages et regroupements de villages, que le projet a appuyés tout au long de sa mise en oeuvre. Par ailleurs, la loi indique qu’une « forêt communautaire est une portion du Domaine Forestier Rural (DFR) affectée à une communauté villageoise ». Dans le contexte local, lors du projet DACEFI-2, l’absence de définition précise du DFR a poussé l’équipe à mener une étude complémentaire pour déterminer l’espace nécessaire et l’espace disponible pour la mise en place de forêts communautaires. Cet atlas est donc également l’occasion de présenter cette synthèse. [less ▲]

Carbon dioxide flux measurements in ecosystem science are mostly conducted over terrestrial areas by eddy covariance technique or the closed chamber method. Both methods are becoming more frequently used over ice and snow covered surfaces. Comparisons between eddy covariance and chamber methods have been carried out over terrestrial surfaces, but carefully designed inter calibration experiments over sea ice and snow are still needed to assess differences and uncertainties. Here we present one of the first comparisons of fluxes over snow covered sea ice estimated from the eddy covariance technique and the chamber method. The measurements were carried out at Young Sound in Northeast Greenland from May 28th to June 28th 2014 starting just before snow started to melt. The comparison shows in general higher fluxes obtained by the eddy covariance method however the disagreement varies depending on meteorological and surface parameters. The flux divergence in relation to varying parameters will be presented and possible causes will be discussed. [less ▲]
