Separation of liquid-liquid dispersions with multiple phases involves different interactions between the different dispersed species present in the system, which makes it difficult to predict e.g. the separation behaviour. Nevertheless such systems are relevant in chemical engineering e.g. for systems involving gas bubbles and simultaneously solid particles like in a fermentation broth. Models for describing the sedimentation behaviour as a basis for settler design are available in principle but have not been systematically validated for variation in size-distribution and e.g. density differences between the various species in the system. Thus, to design technical separation equipment, the separation process has to be better understood, which requires the study of the sedimentation as a first step. This project is focused on the interactions which may occur between each species during the sedimentation e.g. the effect on sedimentation of descending particles when they meet ascending drops. However, a proper study of the sedimentation with fluid phases is difficult due to other phenomena occurring simultaneously, e.g. coalescence. To overcome this issue, the use of gel beads is proposed, which due to their solid interface cannot coalesce. In addition, it is easy to define their parameters which are the density, the hardness and the size distribution. Besides, they can also be preserved during an extended period of time, experiments can thus be reproduced many times with identical beads. During the project, gel beads are designed with different particle size distributions and with different densities. Different batches of the produced gel beads will be mixed to simulate systems with different dispersed phases discriminated via density and different size distributions. With these multiple dispersed phases Experiments will be performed in a settling cell in order to evaluate the overall sedimentation velocity at certain hold up. Simultaneously a new method for measurement of local hold-up profile in the dispersion is tested, which allows hold-up measurement even in opaque systems. Finally sedimentation models found in the literature are compared and adapted to experimental results for predict the sedimentation of systems which involve different dispersed phases. In the presentation the new hold-up measurement will be presented together with an error analysis, experiments on the sedimentation of multiple dispersed phases and the model evaluation will be presented.

This contribution results from a field research by a multidisciplinary group of veterinary and political scientists and gives an analyses of the transformations of an epidemiosurveillance governance system dedicated to animal diseases, when confronted to new emerging threats in the wake of global changes (Fallon et al., in Vertigo 12(3) 2012) . The research field refers to the emergence of bluetongue virus serotype 8 in 2006 in Belgium and it mobilises the results of a survey based on Delphi method involving relevant public servants and scientists, which showed that most of the means proposed by the authorities are based on the logic of known risk management. However we can identify attempts for renewal and organisational learning, especially with the proposal of a new vigilance system, which allows open discussion and reporting through the decision process. In terms of prevention and anticipation of the adverse event), these changes are intended to accommodate the surveillance system reactivity against uncertain and unforeseen events. We question the problems faced by this transformation and its potential for enriching and reconfiguring the conceptualisation of risk management which is currently dominant in the sector. Finally the article identifies two drivers for change in the governance network : by admitting the persistence of unavoidable cognitive uncertainty and by recognizing the importance for opening up arenas of expert knowledge.

In Europe, science research policy is predicated on the understanding that science and technology (S&T) serve societal needs. Accordingly, European Framework Programs urge scientists and technologists to give due attention to societal and ethical aspects of S&T, and to engage with social scientists and humanists when doing research and reaching out to society. Starting from these policy prescriptions and from invitations from befriended life scientists to "get on board," we explore the terms of our involvement as social scientists and humanists in a European Joint Program on radiation protection research (EJP-CONCERT). We illuminate recurring tensions between instrumental, normative, and substantive perspectives on the role of the social sciences and humanities (SSH) in radioprotection research and nuclear S&T. Our aim is to shed light on the controversial and contingent nature of integrating SSH into nuclear S&T, as actors articulate divergent assumptions and expectations about SSH and society. These expectations pertain to the value of SSH research for S&T, issues of trust and legitmacy, and different perspectives on risk and uncertainty. By rendering these tensions explicit we seek to probe the implications for SSH of developing a separate SSH Strategic Research Agenda (SRA) within radiation protection research. [less ▲]

Economic systems and social relationships gain an increasing complexity in prehistoric periods. Despite their symbolic value and their informative potential in these issues, colouring materials (“ochre”, iron oxi(hydrxi)des, cinnabar, etc.) had received scant attention compare to obsidian, flint, metals or igneous rocks. Since the 2000’s, trace elemental analysis (PIXE, XRF, INAA, ICP-MS) and petrographic studies give keys to collect gitological and sourcing data. This methodology has recently improved quantitative knowledge on colouring material’s acquisition modalities and on global technic system itself. Contrasting situations are indeed highlight: archaeological corpus may consist of several raw colouring materials, unequally shared, providing from site range, close diffusion area or far diffusion area. Furthermore, the status of the different geomaterials, the diffusion modalities – direct acquisition, direct or indirect exchanges – and the identity of exporters, transporters and receivers (if any) stay unclear. Two main topics should liven up this session: a fruitful debate on different methodologies depending on geographical contexts and diachronic revue of colouring material procurement through the lens of cultural contexts and site’s status.

The Coma Recovery Scale Revised (CRS-R) is considered as the most sensitive scale to assess patients with disorders of consciousness (DOC). Guidelines recommend repeated assessments because patients might suffer from consciousness fluctuations, but it is not specified how many assessments are needed. The present study included 131 patients with DOC. They have been assessed at least 6 times during a 14-days period with the CRS-R. Results show that 5 CRS-R assessments are needed to reach a reliable diagnosis, and that all the CRS-R subscales are influenced by consciousness fluctuations. We here showed that consciousness fluctuations influence the behavioral diagnosis, and that 5 assessments within a short period of time are needed to get a reliable clinical diagnosis. [less ▲]

Depuis une dizaine d’années, l’Europe développe son propre système de positionnement par satellites (ou Global Navigation Satellites System (GNSS) en anglais), connu sous le nom de Galileo. À la pointe de la technologie, les horloges atomiques embarquées à bord de ses satellites ainsi que les signaux transmis par ces derniers sont extrêmement prometteurs dans beaucoup de domaines. Bien que toujours en phase de test à l’heure actuelle, ce système a déjà conduit à de premières mesures, notamment en matière de positionnement. Parmi ces nouvelles technologies, un signal en particulier semble très prometteur : Galileo E5, aussi appelé Galileo E5a+b ou encore Galileo E5 AltBOC. Ce signal permet d’effectuer des mesures de code et de phase plus précises. Il est également moins sensible au multi-trajet. Grâce à ses caractéristiques innovantes, Galileo E5 devrait permettre d’estimer des positions avec une précision supérieure à tous les autres signaux utilisés aujourd’hui. Une étude comparative des positions estimées avec les systèmes GPS (américain) et Galileo (européen) sur leurs différentes fréquences émises (GPS L1, GPS L2, GPS L5 pour GPS et Galileo E1, Galileo E5a, Galileo E5b et Galileo E5 AltBOC pour Galileo) a été menée dans ce mémoire. Pour ce faire, une combinaison d’observations appelée double différence (DD) est utilisée sous différentes configurations (ligne de base nulle (ZB), courte (SB) et moyenne (MB)) de récepteurs GNSS. Les récepteurs utilisés appartiennent à l’Université de Liège (2 récepteurs Trimble NetR9, 1 récepteur Septentrio XS et un récepteur Septentrio X4). Il ressort de cette étude que Galileo E5 AltBOC présente les observations les plus précises (en ZB, toutes sources d’erreurs éliminées). L’analyse démontre également qu’une précision de l’ordre de quelques décimètres sur la position à déterminer peut être atteinte avec les codes transmis par le signal Galileo E5, et ce jusqu’à 25 kilomètres de distance.

My argument stems from a reading of the fifth study in Cassirer’s The Logic of the Cultural Sciences (1942), devoted to the “Tragedy of Culture.” I contend that this fifth study resolves an observable indecision in Cassirer’s position on cultural productions: to lead man toward greater happiness and freedom, should one strive to uphold traditional forms, or should one abandon old models and create new ones? I believe that Cassirer’s consideration of art historian Aby Warburg’s works (1866-1929) constitutes a defining moment in understanding his answer to that question. This fifth study illustrates the profound impact of Warburg’s model for understanding culture on Cassirer’s philosophy. Contrary to the claims of some exegetes, Cassirer and Warburg’s theoretical positions on the matter are very close. Cassirer’s treatment of the reception of artistic forms (he argues that form reception is never merely a passive act) follows, point by point, Warburg’s theory of the survival (Nachleben) of artistic motifs.

Au terme du cours consacré à la recherche d’informations scientifiques - au programme des bacheliers de la Faculté de Médecine vétérinaire et de la Faculté de Psychologie, Logopédie et des Sciences de l’Éducation (Université de Liège) - les étudiants doivent avoir une vue d’ensemble de la publication scientifique et être capables de (i) mener de manière autonome une recherche d’informations et (ii) de citer correctement leurs sources en respectant des normes bien précises lors de la rédaction de documents. L’évaluation de ce cours est contraignante car il s’agit de cohortes d’étudiants de plus en plus grandes (> 300 étudiants par cursus). Comment évaluer les connaissances ainsi que les savoir-faire de grands groupes d’étudiants ? Jusqu’alors l’examen se composait de questions ouvertes et nécessitait que chaque étudiant ait à sa disposition un ordinateur connecté à Internet. Cette méthode requérait une logistique importante avant et pendant l’examen ainsi que des semaines de correction. Plusieurs alternatives à cette évaluation ont alors été envisagées : travail individuel, travail de groupe, questionnaire à choix multiple… mais elles ne répondaient pas aux exigences fixées par les compétences à évaluer. La piste retenue pour cette nouvelle année académique reste contraignante du point de vue organisationnel (ordinateur pour chaque étudiant) mais permet une correction standardisée, automatisée, fiable et rapide. En effet, le questionnaire combine désormais des questions à choix multiple (QCM ; jusqu’à 9 propositions de réponses) et des questions à choix large (QCL ; jusqu’à 999 propositions). Le QCL présente l’avantage d’être proche de l’évaluation à l’aide de questions ouvertes sans les désavantages de la correction. Nous proposons de présenter ce dispositif évaluatif ainsi que ses avantages et inconvénients par rapport à d’autres méthodes d’évaluation. [less ▲]

La culture constitue pour les migrants et leurs pays d’origine un moyen de maintenir des liens réciproques après la migration. Mais quels sont les enjeux de la mobilisation de la culture d’origine pour l’intégration des migrants dans leurs nouveaux pays de résidence ? Cette présentation analyse le déploiement de la culture du pays d’origine à trois niveaux : celui des pratiques quotidiennes des migrants, des politiques d’intégration et de diaspora et enfin, le niveau des associations, en particulier les centres culturels établis en Europe par les pays d’origine des migrants. Les pratiques culturelles des migrants et les actions et institutions culturelles mises en place par les pays d’origine sont confrontées au cadre légal européen en matière de diversité culturelle mais aussi aux politiques et discours sur l’intégration des migrants. La perspective à la fois anthropologique et sociologique adoptée révèle les processus de domination culturelle qui sont à l’œuvre. Elle permet aussi de questionner l’idée d’identité culturelle en montrant le dynamisme qui caractérise les cultures mais aussi la créativité des communautés locales dans un environnement globalisé. Finalement, on constate qu’une variété de facteurs est en jeu dans les processus d’intégration des migrants, que les dynamiques de la culture elle-même déterminent des appartenances multiples et aussi que les identités se développent au sein des interactions entre cultures. Si on ne peut établir de lien causal et univoque entre les pratiques culturelles liées au pays d’origine et l’intégration des migrants dans le pays de résidence, on peut par contre se référer à la notion d’ethnicité et à sa fonction politique (Comaroff et Comaroff, 2009).

A bosonic many-body system can exhibit the Bose-Einstein distribution in its single-particle eigenstates not only if it is coupled to a heat and particle reservoir, but also if it is subject to a two-body interaction of moderately low strength which couples the single-particle eigenstates with each other. We numerically verify this dynamical thermalization conjecture within disordered Bose-Hubbard rings of finite size whose parameters are chosen such that the dynamics of the system can be expected to be ergodic [1]. This allows one to associate with each many-body eigenstate of the Bose-Hubbard system well-defined (positive or negative) values for the effective temperature and the effective chemical potential which depend on the energy per particle of the eigenstate under consideration [1]. With this information one can then predict the populations of single-particle eigenmodes within each many-body eigenstate of the system according to the Bose-Einstein distribution, without knowing more details about the quantum dynamics of the many-body system.

Non-isocyanate polyurethanes (NIPUs) represent a green alternative to the classical synthesis route of polyurethanes involving toxic isocyanates. This “greener” approach based upon renewable feedstocks and carbon dioxide consists in a two-step reaction. In a first step, carbonated vegetable oils are obtained using an appropriate catalyst by the chemical fixation of CO2 onto vegetable oils formerly epoxidized. Finally, the ring-opening polymerization (ROP) of the carbonated vegetable oil by a diamine provides hydroxy urethanes. In this las step, some organocatalysts have been recently proposed that allows achieving good conversion rates in particular in the case of aromatic diamines. However, the activation mechanism of these organocatalysts is not fully elucidated. In this context, the aim of the present project relies on the theoretical study of a model reaction using DFT calculations. Bicyclic guanidine based catalysts, 1,5,7-triazabicyclo[4.4.0]dec-5-ene (TBD) and 7-methyl-TBD (MTBD), were investigated as catalysts for the reaction between propylene carbonate and aliphatic or aromatic amines. The structural ability of TBD to simultaneously give and receive protons was highlighted by the detailed mechanism investigation. The bifunctional activity of TBD significantly reduces the Gibbs energy of the reaction and allows understanding its higher efficiency compared to its methyl counterpart (MTBD). [less ▲]

Fluctuations in greenhouse gases (GHGs) concentration alter the energetic budget of the climate system. There is high confidence that natural systems related to snow, ice and frozen ground (including permafrost) are affected. Nitrous oxide (N2O) is one of the potent GHG naturally present in the atmosphere, but witch has seen his concentration growing since industrial era. N2O has a lifetime in the atmosphere of 114 years and a global warming potential (GWP) of 298 to be compared to carbon dioxide that has a GWP of 1. N2O is also describe as the dominant ozone-depleting substance emitted in the 21st Century. Yet, there are still large uncertainties and gaps in the understanding of the cycle of this compound through the ocean and particularly in sea ice. Sources and sinks of N2O are therefore still poorly quantified. The main processes (with the exception of transport processes) involved in the N2O cycle within the aquatic environment are nitrification and denitrification. To date, only one study by Randall et al. present N2O measurements in sea ice. Randall et al. pointed out that sea ice formation and melt has the potential to generate sea-air or air-sea fluxes of N2O, respectively. [less ▲]

A la fin des années 90’, les autorités en charge de l’Education dans l’actuelle Fédération Wallonie-Bruxelles ont attribué à l’éducation physique la mission de développer trois domaines de compétences (condition physique, habiletés gestuelles, coopération socio-motrice) pour poursuivre en parallèle quatre finalités (santé, sécurité, expression-communication, éducation sportive). Si les textes officiels semblaient encourager le développement d’un cours d’éducation physique où le sport cédait un peu de terrain à l’activité physique au sens large, force est de constater que, dans les faits, les séances sont restées essentiellement construites par rapport à la pratique de disciplines sportives (dont le choix tend par ailleurs à s’élargir et à se diversifier). Depuis quelques années, sous l’impulsion des formateurs d’enseignants, on constate toutefois une modification très progressive des mentalités. De plus en plus d’initiatives sont ainsi mises en place sur le terrain dans la perspective d’amener les élèves à devenir des citoyens responsables … de leur corps tout au long de leur vie. Cette évolution en faveur de la littératie physique s’accompagne par ailleurs de démarches visant à souligner l’ancrage sociétal de la discipline dont l’apport concret doit impérativement être mis en exergue : le cours d’éducation physique qui présente des liens directs avec ce qui se passe en dehors des murs de l’école. Le professeur d’éducation physique est ainsi de plus en plus présenté comme le potentiel coordinateur de la promotion d’un style de vie actif au sein des établissements scolaires. [less ▲]

Since two decades, a growing number of publications underlines the increase of the sedentariness of the society and, in parallel, that of the number of overweight people. It has been demonstrated that these evolutions will have negative consequences on the health of the citizen at mid and long terms. School is identified as one of the main pillars of the promotion of a physically active lifestyle. By the competences that they acquire during their studies, physical educaiton teachers are considered as the potential corner stone of actions to be implemented in order to allow youth to become citizen responsible of their body and to learn how to use it longlife. That implies reinforcing application of principles that physical educators know very well but that are not necessary integrated systematically in the professional practice. Beforehand to the action on the gym, it means that specific appraoches of teachers education (pre- and in-service) have to be implemented. The presentation proposes to review the current developments and will emphasize the share of good practices in teaching as well as in teacher education. [less ▲]

Bouger plus est un projet visant à encourager la pratique de l'activité physique chez les seniors. Il est né dans le cadre d'une collaboration entre le Service Intervention et Gestion en Activités physiques et sportives de l'Université de Liège, d'une part, la Commune d'Esneux, d'autre part. Après avoir analysé les caractéristiques des habitudes des habitants de la la commune en matière d'activité physique, des interventions ont été implantées auprès d'un public cible particulier: les seniors. Ceux-ci sont considérés comme des personnes de 50 ans et plus. L'exposé retracera les différentes étapes de cette collaboration fructueuse puisque, six ans après le lancement de cette initiative citoyenne, des cycles d'activités sont toujours proposés et rencontrent d'ailleurs toujours plus de succès. Une réflexion sera menée à propos de l'évolution en cours du concept et des options qui se présentent pour la pérennisation de ce projet. [less ▲]

In a context where the classical vision of organizational careers is eroded, this paper explores how Labour Market Intermediaries (LMIs) can secure nonstandard career paths. To characterize LMIs’ emerging roles, we propose a multidimensional grid made up of 6 criteria likely to answer the following questions: 1) where do LMIs come from? 2) who is responsible for the matchmaking process? 3) when do LMIs secure career paths? 4) how do they support professional transitions? 5) what kind of information do they produce and diffuse on the labour market? 6) why do they intervene on the labour market? We validate this analytical framework through its application to five case studies selected to compare the roles LMIs can play in securing careers paths. Beyond the creation of an original grid, results outline two ideal-typical ways of securing transitions. On the one hand, some LMIs offer security by reconstructing internal labour markets and consider workers as ‘quasi-employees’. On the other hand, other LMIs suggest more disruptive solutions in which workers are supported in their job transitions ‘as if’ they were ‘quasi-self-employed’, i.e.: becoming fully responsible for their career. In the conclusion, we discuss societal challenges surrounding these two ideal-typical situations. [less ▲]

Elp3 lysine acetyl-transferase, the catalytic subunit of the Elongator complex, has been assigned multiple roles in gene transcription, DNA methylation and protein translation efficiency. Given the importance of acetylation homeostasis in controlling developmental processes together with recent reports implicating Elp3 in cortical neurogenesis, we investigated its role during inner ear formation. In the inner ear, we detected Elp3 transcript in the sensory epithelia of the entire otic vesicle at embryonic day E11.5. At later stages, Elp3 mRNA is strongly expressed in the vestibular and spiral ganglion neurons. To investigate the role of Elp3 in vivo, we used a conditional knock-out mice (Foxg1Cre) in which the expression of the acetyl-transferase is lost in early otocyst. These mice show obvious vestibular defects as indicated by a stereotyped circling ambulation, head bobbing, retropulsion and the absence of a reaching response in the tail-hanging test. Furthermore, we identified a severe hearing loss in Elp3cKO mice through Auditory Brainstem Responses. We show that Elp3 enzyme is crucial for neuronal survival in the spiral ganglion and in the vestibule and that it ensures a correct innervation pattern in the developing inner ear. In the absence of Elp3, a drastic increase in the number of apoptotic neurons was detected by active Caspase-3 and pH2AX immunostainings, particularly during the early stages of development (between E12.5 and E14.5). Postnatally, the neurons remaining in Elp3cKO cochleae seem to establish synaptic contacts with the sensory cells but show obvious signs of cell damage as evidenced by Transmission Electron Microscopy. Taken together, these data support a role for Elp3 in hearing and balance and point out an important role for acetylation homeostasis during inner ear formation. We are currently investigating the molecular mechanisms underlying Elp3 effect on neuronal survival and pathfinding. [less ▲]

Computerized Adaptive Testing (CAT) has greatly improved the accuracy and efficiency of psychological testing for decades. Multistage Testing (MST) has received much of attention recently. MST is similar to CAT such that it allows the adaptation of the difficulty of the test to the level of ability of a test taker. Specifically, in MST, items are interactively selected for each test taker, but rather than selecting individual items, groups of items are selected and the test is built in stages. Over the last decade, researchers have investigated ways for an MST to incorporate most of the advantages from CAT and linear testing, while minimize their disadvantages. These features include testing efficiency and accuracy, greater control of test content, more robust item review, as well as simplified test assembly and administration. Therefore, MST can be an effective compromise between CAT and linear testing, embedding features and benefits from both designs. Thus, MST becomes of more and more interest to researchers and practitioners as technology advances. This presentation will first provide a general overview of a multistage test (MST) design and its important concepts and processes. It will then present the latest development on CAT and MST using R, the mstR package. The presentation will also illustrate how to simulate MST administrations using mstR package, and discuss some practical issues and considerations for MST from design to applications. [less ▲]

Ancient Egyptian so-called "virtual" relative clauses (VRC) are adverbial clauses that function like relative clauses. Descriptions provided by Late Egyptian grammars inform students of their existence and of the possibility to translate them accordingly. But they are not of a great help if one wants to grasp and describe the Late Egyptian relativization system in a linguistic perspective. The talk, given on the occasion of the international Crossroads V conference, aimed at providing interpretive guidelines based on syntax, pragmatics and Discourse Analysis. In my communication, I showed that Discourse Analysis proved to be very fruitful in clarifying some contexts of use of LEg VRCs as well as some interpretive processes. [less ▲]

The notion of ‘basic vocabulary’ is associated with the linguist and anthropologist Morris Swadesh, who proposed a list of 200 (and later 100) items. These lists, while widely used in historical and comparative linguistics, are based on Swadesh’s intuitions rather than on empirical research. More recently, however, the Leipzig Loanword Typology Project conducted a cross-linguistic survey of loanwords (Haspelmath & Tadmor 2009). One of the results is a 100-item list of basic vocabulary entries — the ‘Leipzig-Jakarta list of basic vocabulary.’ This list is the product of four factors, computed for a database of 1440 meanings in 41 languages: borrowability, representation in the database, analyzability / simplicity, and age. As Tadmor (2009) points out, this is the first list of basic vocabulary items based on extensive cross-linguistic comparison, and it constitutes a ‘full-fledged basic vocabulary’ that ‘comprises the notions normally associated with this concept: stability (our age score), universality (our representation score) and simplicity (our analyzability score), as well as resistance to borrowing (our unborrowed score)’ (2009: 68). In this talk, we examine this list of 100 meanings in order to evaluate the influence of Greek on the Coptic basic vocabulary, or — to put it the other way around — the ‘Egyptian¬ness’ of the Coptic lexicon, which seems to reflect an intense language contact situation. As a first step, Coptic data were collected from Crum (1939), the most extensive Coptic dictionary, for four dialects: Sahidic, Bohairic, Fayyumic, and Akhmimic. All Coptic lexemes associated with a meaning on the list were collected, even if poorly attested. Additionally, a questionnaire was been submitted to Copticists in order to detect Greek loanwords that would also be used for expressing these 100 meanings. Furthermore, we used etymological tools (Černý 1976; Westendorf 1977; Vycichl 1983) in order to attribute an age score (from 0 = Greek loanword to 4 = Old Egyptian) to the lexemes at two levels: the formal level (when is the word first attested in Ancient Egyptian) and the semantic level (when is the Coptic meaning first associated with this word). The vast majority of meanings (ca. 85%) have at least one pre-Coptic Egyptian cognate, most of which are already attested in Old Kingdom texts. As a result of this study, we are able (1) to evaluate the influence of Greek on the basic vocabulary of the main Coptic dialects, (2) to describe the basic vocabulary of Coptic dialects independently and to observe how they differ from one another, (3) to produce a first estimate of the rate of change in basic vocabularies over the course of Egyptian as a whole.

Hooghly estuary and coastal environment in north east coast of India has been strongly affected by the rapid human settlements, intensive boating and tourist activities, deforestation and ongoing agricultural and aquacultural practices. The present work investigated trace elements (TEs, T-Hg, Al, V, Cr, Fe, Mn, Cu, Zn, Co, Ni, Ca, Sr, Li, Be, P, Mo, Ag, Cd, Sn, Sb, Ba, Pb, Bi, U, As, Se) and organohalogen compounds in surface sediment (top 0-10cm) considering 8 sampling sites along the Hugli River Estuary (HRE), India. The studied organic compounds include polychlorobiphenyls (PCBs), hexachlorocyclohexane isomers (HCHs), dichlorodiphenyltrichloroethane and metabolites (DDTs) and polybromodiphenyl ethers (PBDEs). Textural analyses of the sediment reveal an overall dominance of mud. All trace elements could be detected at variable concentrations in the following descending order: Al>Fe>Ca> P>Mn> Cu> Zn> Ba >V >Cr>Sr>Ni> Li >Co >Pb>As >Se >U >Be >Sn>Bi >Ag >Mo >Cd >Sb. A synchronous enrichment of majority of the elements were observed at the site Gangasagar (~100 km south megacity Calcutta), situated at the confluence of Hugli River and Bay of Bengal, which might be attributed to cumulative impact of the physicochemical processes and multiple anthropogenic sources. It is revealed that PCBs and DDTs were the dominant compounds among the organic pollutants accounting concentrations up to 23.5 ng.g-1 and 4.4 ng.g-1 respectively at the site Babughat, adjacent to the megacity Calcutta. The results have implications for pollution in complex estuarine environment in a meso-macrotidal setup where there is significant influx of sediments carrying huge load of inorganic and organic pollutants mainly due to rapid urbanization and industrialization.

In geotechnical engineering, the desiccation cracking of soil is commonly observed. This phenomenon is detrimental to the behavior of earth material and earth structure. Desiccation cracks can lead to the overall failure of many geotechnical structures: • They can affect the slope stability of earth dams or embankments; • They can initiate internal erosion of embankments due to water flow through the cracks; • They can compromise the efficiency of soil barriers such as landfill liners and top covers. Nowadays, the storage of nuclear waste in deep impermeable geological layers is considered. These storages are based on the multi-barrier principle, the last of which being the host rock, typically a clayey material. In this context, maintaining the very low hydraulic conductivity of the host rock is crucial. Unfortunately, the ventilation of excavated galleries causes convective drying of the host material and can lead to crack formation. This work aims to understand in which conditions exactly, during convective drying, does cracking occur in clayey materials. An experimental campaign has been carried out to characterize the drying behavior of Boom clay which is the host rock at the underground research facility in Mol (Belgium). X-Ray micro-tomography has been used to analyze crack development as well as shrinkage. The experiments are used to calibrate the transfer parameters of a convective drying law based on the limit layer model. This calibration is based on agreement of the drying kinetics. A numerical study is then performed and aims at reproducing the behavior observed during the experiments. A thermo-hydro-mechanical coupled model is used to determine the stress distribution during the drying and a tensile failure criterion is suggested to predict crack genesis. Simulations are performed using the in-house built FEM code LAGAMINE. [less ▲]

Most of the foliar primary production of Posidonia oceanica, a major Mediterranean seagrass, sheds in autumn and is exported from the meadow to adjacent areas to form "Exported Macrophytodetritus Accumulations", EMAs. These EMAs are a habitat, shelter and feeding place for an abundant and diverse community of macrofauna. Being very dynamic places and potentially playing a role of transition compartment between water column and sediment, EMAs present high variability in term of physicochemical conditions and more specifically in term of oxygen concentration. Mild to severe hypoxic periods (2 - 0.01 mL O2.L-1) can be observed in situ at different moments of the year, and this variability thus potentially play a structuring role on the macrofauna community. During this study, our main specific questions were (1) Does oxygen stratification occur inside EMAs? (2) If present, how long does it take to observe this stratification? (3) Is the macrofauna impacted and do the dominant species occupy defined positions inside the different micro-habitats? To assess the importance of this impact, an experimental study was conducted in October 2014 near the STARESO oceanographic station (Calvi, Corsica) using an original "layer-sampling" design. The experimental construction was put underwater inside an EMA for 48 hours at a depth of 8m. Samples were collected (N=8) in a 20cm thick EMA using "sealed" boxes to sample every 5cm, from the sediment, to the water column. Oxygen, nutrients and of course the litter itself (containing the macrofauna) were sampled carefully to make sure no exchange occurred between the 4 different layers. After data analysis, the assessment was clear: oxygen stratification occurred in less than 48h and oxygen level inside the layer close to the sediment experienced a fast decrease below the hypoxia threshold (2 mL O2.L-1). Diversity was highly impacted, showing a clear positive link with oxygen concentration. Macrofauna also appeared to follow this oxygen stratification but this response was very species specific. Some species didn't follow oxygen and are present in every layer and most of them were strongly positively linked to oxygen concentration. But a few (Nebalia strausi and Athanas nitescens) were strongly negatively linked to oxygen concentration and were present only in the more hypoxic layers. This experimentation thus confirmed our in situ observations. Oxygen stratification occurred quickly (< 48h) when EMAs were experiencing calm weather. This stratification observed from the water column to the sediment was very marked. Diversity and abundance of most abundant macrofauna species were drastically influenced by this stratification, showing the importance of these micro-habitats in structuring of this macrofauna community.

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.

Laser additive manufacturing techniques – such as laser cladding − were developed in the late 1990s as economic layer-by-layer near-net-shape processes allowing for the production or restoration of complex metallic parts. These techniques are characterised by ultra-fast solidification and cooling rates, thus giving rise to ultra-fine out-of-equilibrium microstructures with potentially enhanced mechanical properties. However, the general quality of a component, as well as its dimensional accuracy, microstructure and final usage properties are strongly influenced by the local thermal history experienced during fabrication. As a consequence, a deeper understanding of the influence of the various processing parameters on the local thermal history during fabrication is of paramount importance, and it can only be reached by combining detailed experimental studies and modeling. Keeping this in mind, the present paper reviews on-going investigations carried out in the Metallic Materials Science Unit of the University of Liege in the laser additive manufacturing of HSS and of stainless steel 316L.

La Maison Aubert et l’esprit d’entreprise de Charles Philipon sont sous la Monarchie de Juillet à l’origine d’un réseau éditorial fructueux et protéiforme fondé sur la diversification des supports (livres, journaux, volumes de pittoresques et petits formats de la littérature panoramique), sur le commerce du produit dérivé (« Muséums », caricatures à la pièce, papiers peints) et sur l’exploitation de l’image pour vendre le texte. On sait que Philipon a lancé les carrières de plusieurs dessinateurs importants comme Daumier et Doré. On sait également qu’il a su attirer des collaborateurs de premier choix dans les équipes rédactionnelles de la petite presse satirique de la Caricature et du Charivari. Ces démarches et la production qui en a résulté ont contribué à fonder autour d’une écurie éditoriale une véritable marque de fabrique, sinon une esthétique. Mais ont-elles pour autant participé à l’émergence de figures d’auteurs ? Louis Huart, Taxile Delord, Edmond Texier, Albert Cler, Arnould Frémy, Maurice Alhoy, James Rousseau et bien d’autres sont demeurés des « petits », attachés aux dépôts de pittoresques et aux panthéons comiques. À travers le cas des productions Aubert, il ne s’agira pas d’examiner comment une figure d’auteur identifiable (de son temps et/ou par la postérité) investit ou bénéficie de la publicité, mais d’envisager la problématique complémentaire et en quelque sorte inverse : les modalités de constitution de la figure auctoriale dans un contexte, un réseau et des supports qui jouent d’emblée et pleinement le jeu publicitaire sous ses formes les plus abouties, s’appuyant sur les stratégies économiques et promotionnelles rendues possibles par l’ère médiatique. L’individualité auctoriale peut-elle prendre forme et statut au sein d’une collectivité prépondérante et ouvertement spéculatrice, celle du commerce de la librairie et de la presse fondé sur la collaboration, le transfert et l’interchangeabilité des identités au profit des fonctions socioprofessionnelles ? En d’autres termes, si l’auteur ne peut se faire un nom sans publicité, (comment) peut-il exister lorsque tout n’est que publicité ? [less ▲]

L’exposé est destiné aux seniors fréquentant l’Université du Temps disponible, soutenue par la Province du Hainaut, Belgique La médecin de famille ou médecine générale (MG/MF) est un métier complexe et méconnu qui demande de solides connaissances fondamentales en sciences de la vie mais aussi en sociologie et en anthropologie autant qu’en épidémiologie. La formation internationale européenne des MG/MF est rythmée dans l’exposé par la définition européenne qu’en donne l’association européenne des Médecins de famille (Wonca Europe) L’exposé, qui débute par une prise de position éthique et politique, est aussi émaillé de diapositives de l’auteur ou d’emprunt à la littérature internationale de médecine de famille et orné de détails de photographies prises par l’auteur. Humanisme et complexité sont les deux thèmes majeurs abordés. La deuxième partie de l’exposé est consacré à la Prévention quaternaire, concept inventé par l’auteur et qui incite les médecins et les patients à chercher une relation constructrice et à se garder des effets pervers de la médecine, tant symbolique que soi-disant scientifique, contrôlée par le profit et génératrice de surmédicalisation de la société.

After attending this presentation, attendees will gain an understanding about specific types of mass murderers and the differences with terrorist offenders. This presentation will impact the forensic science community by providing an in depth psychological and criminological description of mass murderers and terrorist profiles, including warning signs. Pseudocommandos and terrorists kill innocent people. They generally both kill during daytime, plan their offenses and generally expect to be killed during their attack. In a first part and through the study of criminal files, the authors propose a casuistic analysis of a belgian mass murderer. All the aspects of the psychopathology and criminology of this offender will be discussed, including the precise offending sequence. In a second part, the authors will compare the psychopathology of mass murderers and terrorist offenders. Despite their similarities, these two kind of offenders also have strong differences in their psychological and social characteristics.These differences are very important in terms of motivation, state of mind, psychopathology and finally for forensic evaluations. In conclusions, mass murderers and terrorists have common characteristics. Otherwise, their basic psychological and criminological functionings are different. These elements are important and should be considered in forensic evaluations. [less ▲]
