The paper explores the interaction between different kinds of social agents in the funding and management of cult foundations for the dead in the late-classical and Hellenistic period. Textual and archaeological dossiers will be discussed in order to 1) investigate the occupation of sacred space in existing sanctuaries and other public spaces as well as the creation of new sacred places, specifically meant to host ritual practice for dead individuals or groups; 2) provide a comparative analysis of the patterns of establishment, funding and management of cult foundations pertaining to civic, royal, individual or groups' initiatives; 3) explore the forms of interaction between various agents involved, e.g. between civic and private initiative in funding and management. When possible, these considerations will also be integrated with an evaluation of the religious status attributed to the honoured persons, with particular attention to the semantic fields of heroization and deification. Thus an attempt will be made at tracking down possible general trends of religious administration beyond local particularities, and at schematizing these configurations in a model taking into account four factors: the social status of ritual agents and recipients; the religious status acknowledged to cult recipients; the methods of funding and management; the degree of monumentalization and social impact of the cult foundations.

Structural fire engineering has long relied on a prescriptive approach based on isolated member behavior under continuously heating standard fire. By definition, this approach does not allow comprehending the effects of interaction between members of a complete structure nor the effects of real fire exposure. Yet, such effects can have a significant influence on the response of real buildings to fire. Notably, when a structure has survived a fully developed fire, the cooling phase that inevitably follows generates effects that may endanger the structure stability. This has been attested by real structural collapses and poses a specific threat to firefighters. However, the behavior of structures under natural fire and the causes of failure during cooling are still not well understood. This research investigates the response of steel-framed structures to natural fires with the aim to analyze the possible collapse mechanisms during cooling. Numerical simulations by nonlinear finite element method are conducted for different fire scenarios and structural designs. The simulations model the thermo-mechanical behavior of the frames accounting for the interaction between members during the entire fire duration until burnout. Different collapse mechanisms during cooling are highlighted and discussed, including connection failure and progressive collapse under localized fire. In the latter case, collapse of members not directly affected by the fire occurs during the cooling phase. These mechanisms result from a complex combination of several factors, such as the recovery of thermal elongation, the recovery of stiffness, and the prior development of permanent strains in the heated members. The results show that steel-framed structures are subject to collapse during the cooling phase of natural fires. Therefore, natural fires with heating-cooling sequences represent a loading case that should be considered in structural fire analyses and could lead to specific design provisions to prevent the occurrence of collapse during cooling.

Les études consacrées aux interventions de Sartre dans les médias dressent le portrait d’un philosophe frileux à l’égard de la radio, un médium réputé « à sens unique » conformément aux commentaires qu’il en aurait livré dans sa Critique de la raison dialectique. Il n’est pas étonnant dès lors que ces études se satisfont d’une approche essentiellement textuelle de ces interventions et manquent ainsi les usages singuliers que Sartre a fait de ses passages en radio. Partant d’extraits d’interventions enregistrées entre 1946 et 1973, la conférence et projection sonore Réagir à l’archive. Sartre et la radio entend contester l’image d’un philosophe rétif au médium radiophonique tout en dépassant la réduction de ses interventions sonores à leur seule retranscription textuelle. Le rythme des réponses du penseur, leur longueur, le jeu avec l’interviewer dont elles portent les traces, mais aussi les multiples références au direct de l’entretien radiophonique et à la réalité du moment de la diffusion témoignent en effet d’un usage extrêmement lucide d’un médium dont Sartre a tenté d’exploiter toutes les potentialités intellectuelles et politiques propres. On découvrira ainsi qu’avant d’être un matériau d’archive effacé par le texte, les interventions radiodiffusées du philosophe ont été autant de tentatives de (se) jouer de la spécificité radiophonique pour inscrire la pensée critique au cœur même du dispositif médiatique.

Le travailleur du futur et la loi A quoi ressemble le travailleur de demain dans un monde où règnent toujours davantage les technologies de l’information ? Cette question est envisagée sous deux angles. Tout d’abord, l’économie numérique a fait naitre de nouvelles formes de production et d’emploi, telles que « l’économie des plateformes » (Uber, Deliveroo, ….). Celle-ci présente divers atouts pour les entreprises et pour les travailleurs, notamment en termes de flexibilité, mais elles est aussi la source de nouvelles formes de travail précaire. Le travailleur de demain est-il un travailleur du numérique sans protection sociale ? Le deuxième angle est celui du travailleur hyperconnecté. Faut-il envisager de créer un droit à la déconnexion ?

Intense deforestation over large areas is an important component of global models which aim to quantify the transfer of terrestrial siliceous material from the continent to the coast. Hence, there is a need for improved understanding of land use impact on Si export. We present a model that simulates the kinetic dissolution of biogenic Si in a forest soil. A kinetic equation was calibrated based on leaching experiments of soil columns at constant water flux. The calibrated equation was then used to simulate the Si export from a forest soil under varying atmospheric conditions and provided realistic Si concentrations in soil water. The same model was used to simulate the impact of reduced evapotranspiration due to deforestation and consequently increased soil water fluxes on the Si export. Results showed that lower amounts of biogenic silicon dissolved and higher Si fluxes were released to the system once water flux increased. The use of the kinetic dissolution equation for biogenic Si improves our understanding and the modelling of the Si release from soils towards the hydrographic system. [less ▲]

Comme les écosystèmes dulçaquicoles, les écosystèmes marins sont soumis à une pression humaine croissante qui altère la qualité de l’eau et les communautés aquatiques. Près de 98 pourcents de l’eau de notre planète bleue est contenue dans les océans qui constituent le réceptacle final de tout ce que nous rejetons comme déchets (volontairement ou non). Moins accessible, les océans sont méconnus, souvent oubliés ou négligés et considérés comme une zone inépuisable et où tout se dilue ; actuellement encore 80% des eaux usées sont rejetées en mer sans traitement préalable, à peine 2 % des surfaces marines sont protégées. La Méditerranée est particulière à plus d’un égard, bassin de concentration, de faible surface (1% des océans) abritant pourtant plus de 10% de la biodiversité mondiale. Cette petite mer est un modèle pour les océanographes : en mesurant ce qui s’y passe, nous pouvons prédire ce que se déroulera à court ou moyen terme dans le reste des océans. Le laboratoire d’Océanologie est activement impliqué depuis une quinzaine d’années dans la mise au point d’indice de la qualité des masses d’eau côtières. Ces indices sont construits sur base des connaissances du milieu (variations naturelles), par la mesure des niveaux de contamination et des effets (observation et contamination en mésocosme) de cette pollution sur les communautés. Nous avons développé et validé des indices biologiques (PREI : Posidonia Rapid and Easy Index, ICAR Indice Caulerpa cylindracea ; espèce envahissante), de pollution (TEPI : Trace Element Pollution Index, TESVI : Trace Element Spatial Variation Index), de qualité paysagère (LIMA LIttoral MArin) … Ces indices sont utilisés actuellement dans le cadre de la DCE (Directive Cadre Eau), la DCSMM (Directive Cadre Stratégie pour le Milieu Marin) et dans des réseaux de surveillance en Méditerranée, ils sont un relais et un moyen de communication entre les scientifiques et les politiques, les gestionnaires. L’exportation et l’apprentissage de l’utilisation de ces indices sont un atout pour une gestion globale de l’eau à l’échelle de la Méditerranée. Leurs applications sur l’ensemble de la façade méditerranéenne ont, entre autre, mis en évidence l’impact positif de l’application de directives européennes en matière de gestion des eaux par rapport aux côtes de Nord de l’Afrique.

Sixteen weaned male Alpine kids (Capra hircus) were subjected to a 21-day oral daily exposure of 0.05 mg kg 1 BW. d 1 of chlordecone (CLD) and 0.30 mg kg 1 BW. d 1 of each non-dioxin-like polychlorinated biphenyls (NDL-PCBs, congeners 28, 52, 101, 138, 153 and 180). Four kids, identified as the CONTA group, were slaughtered at the end of the exposure, while the remaining animals (n ¼ 12) were fed with specific diets for an additional 21-day decontamination period before slaughtering. Kids from the DECONTA (n ¼ 4) group were fed a control diet, while those from the AC10% and PO8% group received pellets supplemented with 10% activated carbon (AC) and 8% paraffin oil (PO), respectively. CLD and NDL-PCB levels in blood, liver, peri-renal fat and muscles from different groups were analysed to compare the decontamination dynamics of the pollutants and to determine the efficiency of AC and PO to decrease the body levels of pollutants. After the decontamination period, the CLD levels considerably decreased (more than 60%) in blood, liver, muscles and fat. Concerning NDL-PCBs, the decontamination process was much lower. Overall, CLD appeared to be less retained in kids’ organism compared with NDL-PCBs, and the decontamination dynamics of these pollutants appeared to be different because of their specific physicochemical properties and lipophilicity. Furthermore, the dietary supplementation with AC or PO did not significantly affect the decontamination dynamics. [less ▲]

Surface-enhanced Raman spectroscopy (SERS) is a sensitive analytical tool used in the pharmaceutical field in recent years. SERS keeps all the advantages of classical Raman spectroscopy while being is more sensitive allowing its use for the detection and the quantification of low-dose substances contained in pharmaceutical samples. However, the analytical performance of SERS is limited due to the difficulty to implement a quantitative methodology correctly validated. Nevertheless, some studies reported the development of SERS quantitative methods especially in pharmaceutical approaches. In this context, this review presents the main concepts of the SERS technique. The different steps that need to be applied to develop a SERS quantitative method are also deeply described. The last part of the present manuscript gives a critical overview of the different SERS pharmaceutical applications that were developed for a non-exhaustive list of pharmaceutical compounds with the aim to highlights the validation criteria for each application.
