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 ▲]

This paper offers a critical discussion of the so-called argument from the transparency of experience. We recall of the argument against the historical background of phenomenal anti-dualism (Natorp, Wundt, Russell) and identify three difficulties of it. Eventually, we propose an alternative view, which we call phenomenological dualism. On the proposed view, there is a sense in which our mental states may be said to appear to us, hence there is a sense to say that there are mental phenomena. [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 ▲]

The EU-funded 'Odour monitoring and information system based on citizen and technology innovative sensors' (http://www.omniscientis.eu/, OMNISCIENTIS) project has made significant inroads in this regard with the aim of mitigating odour annoyance. To begin with, documents were developed describing the desired specifications for odour measurement, dispersion modelling and information technologies. In parallel, the needs and expectations of all stakeholders, including citizens, regulatory authorities and industrial bodies, were taken into consideration. Citizens' feedback on odour acceptability levels were gathered through smartphones and using the living lab approach. They were further combined with measurements from e-nose and odour dispersion models. Project members developed an Odour Information System that produces validated monitoring statistics and impact levels for local authorities to support environment-related decision-making and for citizens to give them feedback on their complaints. A mobile application is also available, used by citizens to perform odour related observations. Over 5000 observations were sent until now. Besides, two in-situ e-nose sensors and a meteorological station were installed and calibrated in the industrial site in Belgium, serving as pilot. Further 18 industrial parameters are collected in real time and 15 odour field surveys have been performed to understand odour sources and characteristics. The e-nose technology was optimised through tests and improvements to better understand relevant odour parameters at the second pilot site, a pig farm in Austria. Researchers adapted the GRAL-System pollutant dispersion model to develop a fast odour dispersion modelling system using harmonised real-time meteorological data and industrial emission measurements. It was validated with the odour emission rates, olfactometry campaigns and citizens observations. Most of the GRAL-solver components were implemented in Cuda with a speed improved by a factor superior of 100. Project activities were disseminated via project website and factsheets, 3 scientific papers, 13 international conferences and 3 user workshops involving selected citizens, technicians and authorities. Local environmental governance was enhanced through citizen empowerment via monthly meetings and specific methodologies. Better and timely feedback on undesirable odours arising from certain emissions will help in setting evidence-based acceptable odour limits. Ultimately, a particular attention have been addressed by all partners and in particular by involved SMEs in order to ensure the exploitation of the results and enabling the identification of concrete commercial opportunities that may be pursued after the project.
