Pausanias states that the most important Parrhasian sanctuaries were duplicated in Megalopolis in the aftermath of its creation in the 4th century B.C. A noteworthy exception is the sanctuary of Despoina at Lykosoura, which was very ancient according to the author. However, the absence of epigraphical or literary evidence concerning Lykosoura and predating the synoecism and the very limited archaeological material dating to the Archaic and Classical periods suggest that it was the site of a minor cult before the synoecism. The presence of Despoina is not attested before, and it is possible that the cult of the goddess was only developed by Megalopolis, which associated to it several other Arcadian deities and gave it an ancient and local flavour, in order to assert its position as the new cult-centre of Arcadia. Similarly, the sanctuary of Demeter Eleusinia at Basilis may have only been created or developed by Megalopolis, despite its alleged antiquity. This phenomenon finds its closest parallel in the sanctuary of Andania, controlled by the city of Messene. The presence of Demeter and deities associated with her in these sanctuaries, as well as the existence of mysteries, may reflect the growing influence of the sanctuary of Eleusis during the Hellenistic period.

Flood risk in urbanized areas raises increasing concerns as a result of demographic and climate changes. Hydraulic modelling is a key component of urban flood risk analysis. Yet, detailed validation data are still lacking for comprehensively validating hydraulic modelling of inundation flow in urbanized floodplains. ln this study, we present an experimental model of inundation flow in a typical European urban district and we compare the experimental observations with predictions by a shallow-water numerical model. The setup is 5 ll\X Sm and involves seven streets along each direction, leading to 49 intersections. Different inflow discharges and flow partitions were tested. The performance ofthe numerical model is assessed and the upscaling ofthe experimental observations to the field is discussed. [less ▲]

Emergency and disaster management is structured by the complex interaction of natural, social, and technological factors, and contingent on features of culture and organization. Our research serves to highlight how these features come into play and shape emergency planning, anticipation, and response. Based on qualitative and quantitative analyses, we devise more resilient, responsive, and adaptive emergency policies for implicated stakeholders (e.g. policymakers, emergency services, regulators) and society at large. Our research foci include citizen science initiatives and stakeholder forums on contaminated goods in the wake of the 2011 Fukushima accident. Our methods are grounded in vulnerability analysis, which accepts that vulnerability is an inherent trait of contemporary societies. [less ▲]

The solubility of ketoprofen and aspirin in subcritical and supercritical CO2 was measured using FTIR absorption spectroscopy in the large range of temperature of 298.2−353.2 K and pressure of 5−35 MPa. The evolution of the solubility of both active pharmaceutical ingredients (APIs) was fitted using the Chrastil’s equation. In addition, the speciation of both APIs in monomeric and dimeric forms was explored by analyzing the characteristic carbonyl stretching vibrations of the carboxylic acid functions assigned to the dimers and monomers, respectively. Moreover, the evolution of the dimerization constant K of the two drugs as a function of the temperature and the pressure of scCO2 has been reported. [less ▲]

The PISA programme was initiated in 1999 within the Belgian Nuclear Research Centre SCK•CEN to study the societal, political, cultural and ethical aspects of the development and use of nuclear technology and applications of ionising radiation. The programme was launched as the result of an internal reflection acknowledging that insights from social sciences and humanities were required to better explore normative concepts such as precaution and sustainable development, and to understand attitudes towards nuclear technologies and its governance. This presentation elaborates on the objectives of PISA and its main research tracks. It shows that through its multi-disciplinary approach, the PISA programme of the Belgian Nuclear Research Centre SCK•CEN opens pathways towards such integration, and thus contributes to rendering nuclear research more reflective and more responsive towards society. It explicates the interactions between science, technology and society, in general, and the complexity of nuclear technology assessment, in particular. Last, but not least, due do its reflexive character, PISA research creates an epistemologically and socially enriching dynamic in the organisation itself. [less ▲]

Chemical crosslinking is an efficient tool to improve or impart new properties to conventional polymers. Especially, crosslinking imparts remarkable shapeememory properties to poly-ε-caprolactone (PCL) materials. Nevertheless, the processing of networks is often tricky due to infusibility and insolubility of cross-linked chains. Therefore, the synthesis of PCL networks including thermo-reversible crosslinks based on (retro)-Diels-Alder (DA) reaction were developed to allowpreserving the melt-processing while keeping the required mechanical properties below the melting point. This paper aims at studying in depth, such thermo-dependent network formation and stability. Besides conventional swelling experi- ments, Raman spectroscopy was revealed as a powerful tool to follow the formation of the DA adduct during the crosslinking. In combination with rheological measurements, we were able to determine the most appropriate temperatures to form the network (DA crosslinking) and to process it (retro-DA re- action) without degradation of the material.

Les séismes, tsunamis et glissements de terrain sous-marins constituent un risque majeur pour les régions côtières. Prédire ces évènements reste très difficile en raison de la complexité des processus impliqués dans leur déclenchement. L’analyse de longues séries temporelles permet d’évaluer leur fréquence et leur éventuelle cyclicité, mais des données de ce type restent rares. J'ai étudié ces processus dans le Golfe de Corinthe en Grèce, où ils constituent une menace majeure pour les populations. Notre approche a consisté en l’étude des sédiments marins de la partie ouest du Golfe via des profils sismiques, sortes d’échographie des fonds marins, et des carottes sédimentaires. Grâce à ces nouvelles données, un inventaire des grands glissements de terrain sous-marins au cours des derniers 130 000 ans a été réalisé. Par l’analyse de carottes sédimentaires, nous avons aussi identifié des périodes d’intense activité sismique au cours du dernier millénaire. Elles témoignent de l’irrégularité des grands séismes dans la région. Enfin, des failles actives localisées en mer ont pu être cartographiées pour la première fois et leur activité a été estimée.

This study investigates the effect of the ultrafiltration process on physicochemical, rheological, microstructure and thermal properties of syrups from male and female date palm sap. All the studied syrups switched from pseudoplastic rheological behaviour (n = 0.783) to Newtonian behaviour (n〰1) from 10 to 50 s‾1 respectively and present similar thermal profiles. Results revealed that the ultrafiltration process significantly affects the rheological behaviour of the male and female syrups. These differences on rheological properties are attributed to the variation of chemical composition between sap and sap permeate syrups. Furthermore, the effect of temperature on viscosity of the syrups was investigated during heating and cooling processes at the same shear rate (50 s 1). This study provides idea of the stability of the syrup by evaluating the area between heating and cooling curves. Actually, the syrup prepared from male sap permeate is the most stable between the four studied syrups. [less ▲]

This research deals with Sartre's early existential philosophy by resituating it in the field of French post-Comtian philosophy in the early twentieth century and by re-establishing an anthropological moment in which the issue of magic is explored in the psychological and social sciences. Following the different paths of the conceptual exchange through which the notion of magic becomes that the magical in Sartre's view, we study three poles of sartrian phenomenological ontology : intentional consciousness, human reality and being-in-the-world. The hypothesis advanced by this thesis is that the magical, according to different modes ranging from topicalization through obliteration, plays a determining role in the elaboration of existentialism whose genesis is traced here from Sartre's very first writings in 1927.  Faced with the legacy of a positivist anthropology in terms of an analytical methodology, Sartre privileges a synthetic approach and conceives consciousness in its affective and irrational aspects. Images of magical thought are called upon for rethinking openness to the world of consciousness and its relationship to itself and to Others. Returning to Sartrian anthropology, we question how consciousness can be grasped as an irreflexive and absolute spontaneity and how human reality is interpreted through its attitudes and behaviours; in particular through the way it faces its own freedom which is fundamentally and irremediably exposed to contradiction. This structure of human reality as existential project leads Sartre to reconsider being-in-the-world as based in originary dispossession through which ontology is brought back to the magical.

Cette communication interroge la notion de figure comme opérateur de publicisation de l'identité singulière, et distingue à cette fin différents régimes de fiction. Il s'agit d'analyser les dynamiques à l’œuvre entre la (re)présentation de soi et sa réception dans la formation de jugements publics, ce qui suppose de considérer ensemble le niveau de l'histoire racontée et le niveau de sa lecture. L'objectif est de proposer, pour l’analyse des scènes de publicisation de la singularité, un outillage qui soit en lien avec les questions de jugement et de responsabilité. [less ▲]
