Short abstract Based on ethnographic fieldwork conducted among Moroccan women living in Milan hinterland in Italy, this paper aims at exploring the negotiated ways of performing both cultural and social belongings through food and at pointing out how these two dimensions can diverge or overlap in practice. Long abstract Migration constitutes for human beings an opportunity – among others – to develop a reflexive gaze upon one’s own habits (Rodier 2010), food habits in the case under study. In fact, not only changes that may occur in the ways of eating, cooking and supplying of produces, but also new relationships push individuals to question their everyday practices, which are associated with specific meanings. These meanings are socially and culturally oriented and performative, since they permit to state belongings as well as to take part to differently defined groups. In order to study these dynamics, I will present some ethnographic data collected during a research among Moroccan women living in Milan hinterland in Italy, mainly focusing on the history of two of them. The description of food practices, embedded in the narration of the migration experience and its consequences, which in its turn interacts with contextual discourses around immigrants and cultural diversity, reveals unexpected strategies to take social and cultural positionings within the collectivity. The theoretical framework upon which my analysis relies consists of a praxeological approach to subjectivation (Warnier 2001) combined with the consideration of the multi-dimensionality of the self which is derived from the intersectional perspective on identity (Crenshaw 1989; Anthias 2002; Yuval-Davis 2006). Through concrete practices involving food, individuals – women in this case – define their self as a layered complex of belongings, and they do that at both social and cultural level; thus proving how these two dimensions can diverge or overlap.

Drug counterfeiting is a sad and worrisome reality, especially in developing countries where quality control is not effective and sometimes not existing at all despite political will of governments. The consequences are harmful in particular for substandard medicines that pose more threats to populations in those countries due to their direct negative impact on patients such as failure of medical treatment including development of drug resistance and even death. Socio-economic consequences and negative reputation concerning the pharmaceutical industry are also observed. Unfortunately accurate detailed data on such medicines are not easy to obtain. Most of the time available data are often estimated from case reports or studies carried out in a specific area and during a defined period.Health authorities’ in the Democratic Republic of Congo are trying to identify this scourge by set up several strategies to fight against. One of them is built on the best knowledge of drugs from several horizons through the assessment of their quality to allow appropriate measurement. In this context, we have focused our study towards amoxicillin alone and/or combined with potassium clavulanate since it is one the very used medicines in pediatric medications. The formulations are powder for suspension. Two analytical methods were developed based on the USP monography, applying isocratic liquid chromatography. Prior to their application in routine, we evaluated the suitability of these methods through validation applying the accuracy profile of total error. Since it was planned to transfer the methods to DRC, several operating factors were taken into account namely operator, day and equipment. Interesting results were obtained in terms of trueness (relative biases below than 2.3%), precision (RSD of Intermediate precision below 2.8%), accuracy (beta-expectation tolerance intervals between -6.0% and 3.8%) for the concentration levels of interest. The latter were able to allow monitoring the quality of the two active ingredients here above in the 65 samples from Congolese market. They were collected in Kinshasa, Lubumbashi, Matadi and Kolwezi at official and non-official medicines distributors, in peripheral area. The dramatic results obtained confirm that substandard and counterfeit medicines remain a crucial problem on public health in low-income countries. Appropriate measures are really needed to set up the drug quality improvement. [less ▲]

Understanding consciousness remains one of the greatest mysteries for science to solve. How do our brains work? How can we know if some patients in coma have any consciousness left and how could we communicate with them? What are near-death experiences? What is brain death? What happens in our brains during dreaming, hypnosis or meditation? At present, nobody understands how matter (our trillions of neural connections) becomes perception and thought. We will here briefly review some neurological facts on consciousness and impaired consciousness. Thanks to recent advances in (neuroimaging) technology, the mapping of conscious perception and cognition in health (e.g., conscious waking, sleep, dreaming, hypnosis, meditation, sleepwalking and anesthesia) and in disease (e.g., coma, near-death, “vegetative” state, seizures, hallucinations etc) is providing exiting new insights into the functional neuroanatomy of human consciousness. Our perception of the outside world (sensory awareness; what we see, hear, etc.) and our awareness of an inner world (self-awareness; the little "voice" inside that "speaks" to ourselves) seemingly depend on two separate networks we could recently identify. Philosophers might argue that the subjective aspect of the mind will never be sufficiently accounted for by the objective methods of reductionistic science. We here prefer a more pragmatic approach and remain naively optimistic that technological advances might ultimately lead to an understanding of the neural substrate of human consciousness. [less ▲]

Plasma membranes are complex entities common to all living cells. The basic principle of their organization appears very simple, but they are actually of high complexity and represent very dynamic structures. The interactions between bioactive molecules notably peptides, and lipids are important for numerous processes, from drug bioavailability to viral fusion. The cell membrane is a carefully balanced environment and any changes inflicted upon its structure by a bioactive peptide must be considered in conjunction with the overall effect that this may have on the function and integrity of the membrane. As a general concept, understanding the mechanism at the molecular level by which bioactive molecules interact with cell membranes is of fundamental importance. Lipid specificity is a key factor for the detailed understanding of the penetration and/or activity of lipid-interacting peptides and of mechanisms of some diseases. Further investigation in that way should improve drug discovery and development of membrane-active molecules in many domains such as health, plant protection or microbiology. In this talk, we propose to overview some complementary “in vitro” and “in silico” biophysical approaches that can give information about lipid specificity at a molecular point of view. Our strategy is illustrated on different bioactive peptides such as antimicrobial peptides, peptides involved in human diseases or in plant cell signalling. [less ▲]

Although aging is related to decline in recollection as measured by so-called objective measures, older adults’ subjective experience of recollection remains sometimes stable. Such dissociation could suggest that younger and older adults use details with different diagnosticity to make subjective recollection judgments. However, the type of details that are reported as bases for recollective experiences by younger adults can also vary as a function of context. Here, we directly investigated age-related changes in recollection and familiarity in different memorability context. Participants studied one set of words in a medium level of processing (LOP) task, and another set of words with either a shallow or deep LOP task (i.e., low vs. high memorability context, respectively). At test, participants discriminated between old and new words and provided information about the basis of their recollective experiences. In both age groups, medium items received more recollection judgments in low (vs. high) memorability context. These recollections seem to be associated with internal information (thought, image, emotion). In contrast, external details (list source, appearance, list position) more often accompanied recollection of medium items in high (vs. low) memorability context. We discuss this effect in terms of Gruppuso et al.’s (1997) functional account. Like younger adults, what older adults deem to be an experience of remembering arises from the functional utility of the recollected information for accomplishing the task. In the low (vs. high) memorability context, the information recollected for medium items more easily met the functional definition of remembering established by participants during the test.

In the rural areas of Bolivia, where about a third of the people lacks access to reliable electricity, both a complex geography and a scattered population make the costs of extending the national grid prohibitively high. As an alternative, we evaluate the feasibility of an isolated micro-grid, composed by Li-ion batteries and Photovoltaic (PV) panels, for a Bolivian remote community living without access to electricity. We surveyed two remote rural villages to assess the potential electricity consumption patterns of the population once provided access to electricity. We estimated the average demand profile using the tool LoadProGen, and we collected local techno-economic and solar irradiation data of the zone. We employed such data as inputs in a robust linear programming-based optimization tool to determine the capacities of the Li-ion battery bank and the PV array thatminimize the net present cost (NPC) of the system.

INTRODUCTION: Following severe acute brain damage, patients typically evolve from coma to an unresponsive wakefulness syndrome/vegetative state (UWS/VS; wakefulness without awareness) and later to a minimally conscious state (MCS; fluctuating but consistent nonreflex behaviors). MCS is subcategorized in MCS+ (i.e., command following) and MCS- (i.e., visual pursuit, localization of noxious stimulation or contingent behaviours). Reliable and consistent interactive communication and/or functional use of objects indicate the next boundary – emergence from MCS (EMCS). To date, there is still no reliable predictive model of recovery from the UWS/VS and the MCS. A better understanding of patients' outcome would help in decisions regarding patients’ care and rehabilitation, as well as end-of-life decisions. METHODS: We collected demographic information, acute care history and longitudinal follow-up of patients in UWS/VS and MCS admitted in 15 expert centers in Belgium (via the Belgian Federal Public Service Health). Patients were evaluated at 1, 3, 6, 12 and 24 months post injury with the Coma Recovery Scale-Revised and the diagnosis was based on internationally accepted criteria of UWS/VS, MCS or EMCS. Results were considered significant at p<0.001. RESULTS: 24 months follow-up was available for 476 patients including 261 diagnosed in UWS/VS (88 traumatic, 173 non-traumatic) and 215 diagnosed in MCS (80 traumatic, 135 non-traumatic) one month after the injury. Patients who were in MCS one month after the insult were more likely to recover functional communication or object use after 24 months than patients in UWS/VS. Moreover, functional recovery occurred more often in MCS+ (79%) as compared to MCS- (29%), and mortality rate was more important in MCS- patients (68%) as compared to MCS+ (21%). Comparisons within UWS/VS and MCS groups based on etiology showed that traumatic patients had a better outcome at 24 months than non-traumatic patients. Among non-traumatic patients, no difference was found between anoxic patients and patients with other etiologies regarding functional recovery. CONCLUSION: Our study highlights that the outcome is significantly better for patients who are in MCS one month post-injury as compared to patients who remain in UWS/VS at that time. Concerning MCS patients, the outcome is significantly better for patients who are MCS+ one month post-injury as compared to patients who are MCS- at that time. This study also confirms that patients with traumatic etiology have better prognosis than patients with non-traumatic causes. [less ▲]

While the aggregation process of superparamagnetic colloids in strong magnetic eld is well known on short time since a few decades, recent theoretical works predicted an equilibrium state reached after a long time. In this talk, we present experimental observations of this equilibrium state with a twodimensional system and we compare our data with the predictions of a pre-existing model. Above a critical aggregation size, a deviation between the model and the experimental data is observed. This deviation is explained by the formation of ribbon-shaped aggregates. The ribbons are formed due to lateral aggregation of chains. An estimation of the magnetic energy for chains and ribbons shows that ribbons are stable structures when the number of magnetic grains is higher than N=30. [less ▲]

Graft-versus-host disease (GVHD) remains a major cause of morbidity and mortality after allogeneic hematopoietic stem cell transplantation. Several studies have suggested that rapamycin (RAPA), an mTOR inhibitor with immunosuppressive properties, may reduce GVHD severity and mortality, possibly by promoting regulatory T cells (Tregs). However, few data have been reported about the impact of this drug on overall T cell population. The present work aims at investigating the mechanisms by which RAPA impacts GVHD in a humanized mouse model of GVHD (NSG mice infused with human PBMCs). We observed that RAPA injections significantly reduced xenogeneic GVHD lethality and severity. RAPA dramatically reduced human cells chimerism in RAPA mice and increased CD4+/CD8+ T cells balance due to a lower proliferation of CD8+ T cells. In addition, the frequencies of naive CD4+ and CD8+ T cells were higher and the CD4+ T cells showed a reduced effector phenotype (CD45RO+CD27-). Further, the differentiation of helper T cells (Th1, Th2 and Th17) was significantly decreased in treated mice. Tregs were positively affected as RAPA up-regulated their expression of BCL-2 and KI67 as well as their STAT5 phosphorylation level, leading to higher Treg frequency in treated mice. Altogether these data suggest that RAPA ameliorates GVHD by lowering cytotoxic and effector CD4+ T cells frequency as well as promoting Tregs. [less ▲]

Ethylene is an unconjugated monomer difficult to copolymerise in a controlled fashion using common radical or coordination-insertion polymerisation. Cobalt-mediated radical polymerisation (CMRP) provides a powerful means to radically copolymerise ethylene in a controlled fashion under mild conditions.[1][2] In addition, different copolymer structures, such as block or alternating, can be accessed. ACO2-based cyclic carbonate was chosen as a promising comonomer but conflicting reports on the copolymer structure have been reported.[3][4] To better understand the copolymerisation behaviour of this monomer, model copolymerisations with vinyl acetate were performed and are reported below with the aim of gaining insights into the copolymersiation behaviour, which will allow us to better tackle ethylene copolymerisations.

Continuous-flow micro- and mesofluidic reactors come with inherent properties that can be advantageously utilized for expanding the horizon of synthetic organic chemistry. Accurate control over local process parameters, even under extreme conditions, inherent safety, production homogeneity and seamless scale-up are amongst the most important assets of continuous-flow chemistry. Besides, flow chemistry enables the design of efficient multistep processes with significantly reduced footprints. In this lecture, we will discuss some of the most fascinating aspects of continuous-flow micro- and mesofluidic reactors in the specific context of preparative organic chemistry. Multiple examples illustrating the development and implementation of continuous-flow multistep strategies for the synthesis of high-value added organic targets will be presented. [less ▲]

It is now commonly accepted that, in ageing, recollection processes are impaired and familiarity seems to be relatively preserved. In this study, we were interested in the differences between younger and older participants regarding cerebral activity during encoding depending on whether the item later elicited recollection or familiarity. Twenty young volunteers and 19 older volunteers were presented visual stimuli depicting objects. After a first fMRI session in which the items were encoded, they underwent a recognition memory task in which they judged whether items were Remembered, Familiar or New. Data were analysed using SPM8, with an event-related design comparing modifications in cerebral activity between the two subjects groups during encoding (1) for the items leading to recollection compared to those leading to familiarity, and (2) for the items associated with familiarity compared to those which were not recognized. Results showed that older adults displayed a heightened activity in regions of the default-mode network for subsequent recollection. As it does not appear to be deleterious, it could stem from a more frequent use of self-referential appraisal as an encoding strategy in older adults. Furthermore, they show supplementary contralateral activations in frontal and temporal regions, which could be indicative of dedifferentiation or attempted compensation. To conclude, it appears that despite relying less on elaborative encoding, older adults seem to be able to perform recollection using qualitatively different strategies than young adults. [less ▲]

Short C fibres–Mg matrix (AZ91D) composites have been produced by friction stir processing sandwiches made of a layer of C fabric stacked between two sheets of Mg alloy. The process parameters have been optimized to ensure a good fiber distribution. 3D X-ray tomography reveals that the fibers orient like onion rings. Thermal treatments have allowed to modify the flow stress level of the matrix material. Tensile testing inside the scanning electron microscope have revealed the decohesion at the fiber/matrix interface if the fibers are preferentially oriented perpendicularly to the loading direction. Modelling allows to estimate the stress needed to initiate this decohesion is about 250 MPa, i.e. appearing early in heat treated samples. To compare with different loading conditions, micro-compression and instrumented micro-indentation testing have also been performed. The consequence of the loading path on the decohesion is discussed. [less ▲]

Biomass Combined Heat and Power (CHP) plants connected to district heating networks (DHN) are recognized as a very good opportunity to increase the share of renewable sources into energy systems. However, as CHP plants are not optimized for electricity production, their operation is profitable only if a sufficient heat demand is available throughout the year. On the other hand, these plants often work for baseline operation and back-up boilers are used to supply the peak demand. To extend the use of the CHP plants and reduce costs, conventional fuel use and emissions, it is proposed to study the feasibility of using additional high temperature heat storage as retrofit of an existing CHP plant. This work is based on a simple and effective methodology that provides accurate estimations of economic, environmental and energetic performances of CHP plants connected to district heating networks. The DHN of the University in Liège (Belgium) is used as an application framework to demonstrate the effectiveness of the selected approach. The potential energy and pollutant emissions savings and resulting energy costs are estimated and the current policy limitations will be discussed. [less ▲]

Several energy efficiency concepts and comfort models emerged in the last 15 years seeking high performance buildings and optimal occupant comfort conditions. The aim of high performance buildings is to reduce the carbon footprint and energy consumption of buildings while maintain a fit to purpose comfort. In this context, this work raises the question of fir to purpose comfort models that can from one side reduce the energy consumption of typical office buildings in hot climates (cooling dominated) while on the other side ensuring indoor thermal comfort. Indeed, studies that address energy efficiency are many, however it is in most cases applied to temperate or cold climates and barely explored for hot climates. The objective of this paper is to (1) combine several comfort models for a net zero energy building in hot climates, (2) select the comfort model that shows the optimal comfort quality of indoor environment and (3) compare the building's annual energy consumption for each used comfort model. To respond to our research problems, a methodology has been established, which goes through several phases. First identifying the different comfort models comfortable to use in hot climates (ISO 7730 / EN 15251 / adaptive ASHRAE / Givoni), secondly selecting a typical validated office building model as a reference building and finally selecting representative cities in the Mediterranean arid and hot climate (Algiers / Sicily / Cairo / Dubai). The study used building performance simulation to generate the different results on the energy consumption and the operative temperatures of the different models of comfort in each city. The paper ultimately identifies the fit to purpose comfort models for a medium size net zero energy office building in hot climates. The paper presents a comparison that can help building professional to identify the most appropriate comfort model that allows optimizing energy consumption, ensuring thermal comfort for robust perfromnce of net zero energy buildings in hot climates.

Use of Information Technologies in Egyptology can be traced back to the early 1960s, when first efforts were made in documenting Meroitic scripts or emblematic corpora such as the Pyramid Texts. With the rise of the Digital Humanities in the mid-2000s, many new academic projects that implement IT solutions not only as a way to manage and present data, but also to produce, process and analyse the material, have come to light in the field. The aim of this paper is to give a survey of current digital projects related to the study of ancient Egyptian and Coptic texts. Our goal is not to be exhaustive, but to discuss the methods and tools that are being used and to describe the variety of scholarly practices. The first set of projects to be examined are those related to digital text editions and annotated corpora (including the types of representation format). Second, the question of how to handle the complex writing systems of Ancient Egypt will be addressed by looking at projects that focus on encoding (Manuel de Codage vs Unicode), on establishing hieroglyphic sign-lists (the Thot-Sign-List), on palaeographical databases and on ways to OCRize original texts efficiently. The issue of interoperability and data sharing will then be investigated through a presentation of several related projects working on a XML/TEI interchange format as well as on digital resources for enabling a Linked Open Data approach to the ancient Egyptian written material (http://thot.philo.ulg.ac.be/). Finally, we will argue in favour of a coherent data model so that encoding of data and metadata is done in the most effective way. [less ▲]

In order to quickly reach incident locations, emergency services have to fairly distribute their resources on the territory. This distribution is based on an analysis which depends on heterogeneous spatial data like past interventions (recurring risk), specific geographical places (sporadic risk), road network or socio-economic variables. On the other hand, Spatial Online Analytical Processing (SOLAP) tools are designed for the collection and the analysis of large spatial data sets. In this study, an original raster SOLAP model is implemented for emergency services of Brussels agglomeration. It allows decision-makers to freely generate risk maps (continuous fields), depending on several dimensions (time, intervention type, risk type, etc.), and to compare them with the accessibility of firefighters and ambulances. Simulations can also be performed on resources locations to see their impact on the main accessibility. [less ▲]

Le dispositif du remembrement-relotissement, aussi appelé « Association Foncière Urbaine » en France, est un outil foncier qui permet de réaménager le maillage parcellaire et les espaces publics. Il a pour finalité de matérialiser un projet urbain et il est associé au transfert à une structure de copropriété des droits de propriété relatifs aux terrains nécessaires à la réalisation du projet en question. Il revient ensuite à cette structure de copropriété de gérer le développement du périmètre. À l’issue de l’aménagement, les propriétaires sont rétribués proportionnellement à la valeur de leurs apports fonciers respectifs. Le remembrement-relotissement est considérée comme une « Belle endormie » de l’aménagement . En effet, alors que ce dispositif présente de nombreux avantages (mobilisation du foncier à faible coût, développement de projets intégrés…), il n’est que très rarement appliqué sur le terrain . C’est dans ce cadre que se situe notre proposition, dont l’objectif est de chercher à comprendre les raisons qui limitent l’usage de cette procédure ainsi que les leviers susceptibles d’enfin banaliser sa pratique. Notre intervention sera structurée en trois parties. En première partie, nous développerons les résultats d’une analyse ayant cherché à comprendre la non-utilisation du dispositif au sein du contexte wallon . Ce travail a mis en avant que le remembrement-relotissement souffre d’une mauvaise image auprès des experts wallons de l’aménagement du territoire. Le problème fondamental réside dans la faible faisabilité liée à l’incapacité de mobiliser de concert un nombre suffisamment élevé de propriétaires. La seconde partie de notre intervention sera consacrée à la situation néerlandaise. Aux Pays-Bas, le remembrement-relotissement n’est pas non plus un outil fréquemment utilisé, ce qui s’explique par la tradition de production foncière publique. En effet, il est inutile de chercher à travailler avec les propriétaires lorsque les collectivités locales sont directement à la manœuvre pour mettre en place les projets de développement. Pour autant, en raison de la crise du modèle néerlandais de la production foncière publique, le remembrement-relotissement est aujourd’hui considéré par les autorités néerlandaises comme un outil très important afin de continuer à contrôler les montages opérationnels tout en limitant l’implication financière des collectivités. Il ressort de la comparaison entre les Pays-Bas et le Wallonie que le différentiel de confiance entre acteurs est une explication fondamentale de l’opposition entre les deux contextes. Dans ce cadre, la troisième partie de notre intervention rendra compte d’une recherche en cours qui vise à objectiver l’impact des cultures d’aménagement sur les montages opérationnels. Ce projet, qui s’appuie sur le champ de l’économie comportementale , vise en particulier à traiter des thématiques de l’aversion face aux risques et de l’importance de la confiance dans le développement des partenariats et des coopérations.

The criterion of 3% of stuttered disfluencies – (part-)word repetitions, sound prolongations and blocks – is often suggested to diagnose the stuttering in children (e.g., Boey et al., 2007; Yairi & Ambrose, 2005). There is a long-lasting debate among scholars about the relevance of considering monosyllabic word repetitions as stuttered disfluencies, given their high frequency in typically developing children (e.g., Howell, 2013; Wingate, 2001). Yet, these are the prime characteristics that prompt identification of early stuttering by parents (Yairi & Ambrose, 2013). Nevertheless, very few normative data exist concerning the disfluencies occurring in the speech of normally fluent children (Tumanova et al., 2014), and none exist in French. The aim of this study is to examine the need for reference data in French in order to distinguish typical developmental disfluency from stuttering. We used the CHAT transcription system and the coding conventions of FluencyBank to transcribe and analyse the speech disfluencies of twenty monolingual, French speaking children who do not stutter, aged 4 years. FluencyBank (Bernstein-Ratner & MacWhinney) is a shared database for the study of the development of fluency in both normal and disordered populations. It is a project of Talkbank that seeks to archive and facilitate sharing of data relevant to fluency research. [less ▲]

High performance buildings including net zero energy buildings (NZEB) are facing difficulty to become market mainstream in warm and hot climates. Beside the economic there are serious technical and design challenges that hampers design teams design, construct and operate NZEB in mixed and cooling dominated climates. There is a difficulty to make the Passive House standard cross the heating dominated climatic zones in Northern and Central Europe to get implemented in mixed or cooling dominated climates as an ultra-energy efficient building concept. There is a need for setting new climate adaptive energy efficiency target metrics for NZEBs in warm and hot climates. This paper presents guidance and recommendations on the necessary performance target metrics for NZEBs and makes them explicit. Results are based on cross analysis of several case studies, presenting an overview of challenges and providing recommendations based on available empirical evidence to further lower those barriers Worldwide with a focus on the European construction sector. By defining the performance thresholds for NZEBs including the metrics we offer design team the possibility of verification and design assessment during early design decision making phases to instil a kind of practical, evidence based and quantifiable guidance for high performance buildings and in particular NZEBs.

Regulation in terms of greenhouse gas emissions becomes more and more stringent and the fuel consumption targets decrease. In order to meet these demands, vehicle electrification has increased over the last decade. With the arrival of plug-in hybrids and battery electric vehicles, efficient battery cooling system becomes a necessity and has to be integrated into the vehicle thermal management. One of the possibility is to integrate a chiller in the air conditioning system for extreme operating points. Moreover, this kind of system can be dedicated to luxury or large passenger cars for which a secondary evaporator is present to guarantee the comfort for rear passengers. The main challenge of this air-conditioning architecture is to maintain simultaneously the cabin thermal comfort via one or two evaporators on one hand and to maintain the battery cells in an ideal temperature range on the other hand.

The use of foraminifers as bioindicators of pollution in coastal and paralic environments has undergone a very fast development. Among various criteria, morphological anomalies are sometimes considered as pollution indicators. This paper presents a synthesis of the studies correlating foraminiferal assemblages and environmental concerns. Sediment cores retrieved along the northern coast of Sfax (Tunisia) are used to monitor the response of benthic foraminifera to modern pollution and environmental stress. Sediment samples were separated immediately after collection for benthic foraminifera analysis. Binocular microscope and the Scanning Electron Microscope (SEM) were carried out to identify the most significant, normal or deformed, specimens. All observations confirmed that foraminifera may be used as indicators of pollution after deconvoluting from natural impacts. The most sensitive foraminifera identified in the study area are Ammonia tepida, Ammonia beccarii, Elphidium crispum, Peneroplis pertususles Miliolidae, Peneroplis pertusus et Rosalina sp and Peneroplis planatus. The morphological study of benthic foraminifera from surface sediments attests for the pollution of the actual coast. This pollution is recorded in the benthic foraminifera tests mainly as shell deformations, chambers or streaks or abnormal colors. [less ▲]

INTRODUCTION: Sessile serrated adenoma/polyp (SSA/p) is a precancerous lesion, mostly located in the right side of the colon (cecum, ascending and transverse colon). The difficulty is to visualize this lesion during colonoscopy because of its subtle appearance. MATERIAL AND METHOD: We compared proteomes of serrated polyps (SSA/p) and conventional adenomas using residual human formalin fixed paraffin embedded (FFPE) samples. FFPE-FASP method was applied on samples before label free proteomic analysis. Immunohistochemistry (IHC) characterisation of one candidate marker was performed for tissue validation on an independent set of samples including: conventional adenomas (low and high-grade dysplasia), serrated polyps (hyperplastic polyps, SSA/p and traditional serrated adenoma) and finally normal colon (taken at the margin of colorectal cancer (CRC) or of diverticular disease). RESULTS: Proteomics provided 765 proteins (out of 5992 proteins identified) significantly discriminating conventional adenomas from serrated lesions. We selected 53BP1 (Tumor suppressor p53-binding protein 1) among these for IHC validation, because of its tumor suppressor gene function and role as a mediator of DNA damage checkpoint. 53BP1 appeared significantly up-regulated in proteomes of low and high grade adenomas compared to these of normal tissue and SSA/p. 53BP1 IHC signal was located in the nucleus and the percentage of positive nucleus decreased in serrated polyps, especially in crypts and in the border epithelium, confirming part of the proteomic results. CONCLUSION: This study highlights potential marker proteins, including 53BP1 from which IHC signal was strongly decreased in some serrated polyps. The loss of 53BP1 has been associated with tumour progression and poor prognosis, while little is currently known about its involvement in precancerous CRC lesions. 53BP1 decrease of expression in the nucleus and therefore possible loss of function in some epithelial cells could reflect important changes occurring during dysplasia to neoplasia progression in serrated lesions.

Depuis le milieu des années 2000, nombreux sont les musées d’ethnographie à avoir développé une politique d’ouverture à l’art contemporain, consacrant même dans leur programmation des espaces réservés à des résidences d’artistes ou à des expositions carte blanche. C’est le cas notamment du Weltkulturen Museum de Francfort, du Musée national des cultures du monde de Göteborg en Suède, du Pitt Rivers Museum d’Oxford, du Musée de la Civilisation à Québec, du Tropenmuseum à Amsterdam ou, plus récemment encore, du Musée de Tervuren et du Musée du quai Branly à Paris. Pour comprendre ce qui s’apparente à un véritable phénomène de mode – cette ouverture à la création vivante concernant par ailleurs l’ensemble du monde muséal –, il convient de s’intéresser aux premières interventions d’artistes dans les musées d’ethnographie, lesquelles remontent au milieu des années 1980, un moment charnière dans l’histoire de ces insitutions. Sous l’impulsion des Postcolonial Studies, les musées d’ethnographie extra-occidentale entrent progressivement dans une phase de redéfinition de leur mission et dans un processus d’auto-évaluation aux conséquences plus ou moins grandes sur les dispositifs d’exposition et de réception des objets ethnographiques. En axant notre attention sur trois expositions pionnières – celles d’Eduardo Paolozzi au Museum of Mankind à Londres (1985), de Fred Wilson au Maryland Historical Society à Baltimore (1992) et de Toma Muteba Luntumbue au Musée royal de l’Afrique centrale à Tervuren (2000) –, nous voudrions non seulement comprendre le rôle joué par l’art contemporain dans le procesus de refondation et les stratégies d’exposition des musées d’ethnographie extra-occidentale, mais saisir aussi la nature à la fois féconde et ambiguë des liens tissés entre le monde des anthropologues et celui des artistes. Le célèbre article d’Hal Foster, L’artiste comme ethnographe, servira de base à nos réflexions. [less ▲]

During the middle Palaeolithic, the northern France was only occupied by Neanderthals groups. However, successions of glacial and interglacial cycles explain a complex and discontinuous settlement, raising complication in the study of its dynamics at a regional scale. Therefore, some aspects of Neanderthals behaviour are still mischaracterize: in most cases, the function of the site and its territorial management over the northern France have to be specified. The spatial analysis of open air sites from northern France will help us to answer those questions. However, for Middle Palaeolithic sites, we can't see systematically on the field the spatial organisation directly, we sometimes need modelization. Therefore, we started to build a spatial analysis protocol adapted to this site and applied to such sites. The sites of Caours (Somme, France) and Beauvais (Oise, France) are two open air sites that are exceptionally well preserved and displaying a large amount of faunal and lithic rests. Both are perfect candidate to apply and test the new protocol. First results proved that for each site the existence of a spatial organisation as remains concentration zones. Then, we characterize this areas – number, distribution. Finally, we were able to associate them to human activity areas like hearths, butchery or knapping areas. [less ▲]

Chronic colonic inflammation in ulcerative colitis (UC) may induce dysplasia, which can itself progress and transform into neoplasia. Diagnosis of dysplasia in UC remains difficult particularly when tissue inflammation is present. The aim of this retrospective pilot study was to highlight proteins specifically associated with inflammation induced dysplasia in UC. We performed a pilot experiment on 15 Formalin-Fixed, Paraffin-Embedded (FFPE) samples isolated from 5 cases of UC patients with a Polypoïd Pedunculated dysplasia (UC-PP). We compared the proteomes of the UC-PP, the inflammatory (UC-I) and the normal (UC-NL) tissues of each patient. We performed Laser Capture Microdissection (LCM) in order to collect only epithelial cells, avoiding inflammatory infiltrating ones. Label free proteomic analysis using a 2D-nanoUPLC coupled with a hybrid Quadrupole-Orbitrap was applied, as well as differential analysis on the paired samples. Immunohistochemistry (IHC) characterisation of one of the selected proteins of interest was used for validation. Out of 985 quantified proteins, 7 were found significantly more abundant in UC-PP compared to UC-I tissues, with 6 being only detected in UC-PP using proteomics. One of these is Solute Carrier Family 12 member 2 (SLC12A2), also known as Na-K-2Cl co-transporter 1 (NKCC1), a protein involved in ionic balance, in T-cell migration promotion and in some features involved in cancer development like proliferation, migration or invasion. IHC results obtained were in correlation with proteomic results and showed that SLC12A2 was more abundant in UC-PP tissue than in UC-I and UC-NL tissues, with a signal clearly delimiting the dysplastic region from the surrounding inflammatory tissue. This pilot experiment shows a different proteomic profile in inflammation-associated dysplasia and simple inflammation. This should be replicated using other types of dysplasia in IBD. SLC12A2 could be a potential biomarker of inflammation-associated dysplasia. [less ▲]

The notion of Landscape Observatory (ELC 2000), in the work of LabVTP at the Faculty of Architecture in the University of Liège (Wallonia-BE), has been linked with the concept of Landscape Laboratory (R. Gustavsson) in order to enhance and underline perceptive, experiential and active dimensions of sites, responding to the Universities’ missions required by the ELC: education and sensitization. Lab Pay(s)age, as a new typology of landscape laboratory, has developed methodological tools for landscape research, based on a multi-scale and diachronic reading of the territory, where natural and artificial traces are the complementary elements to be reinterpreted and relaunched in new participative scenarios. The Meuse valley, reshaped by deep transformations, is the main topic for researches, concerning specific morphological, typological and social characters. All along the river, the scars of industries mark the territory as a land in search of new cycle of life1. The regeneration of abandoned industrial sites, as a practice of territorial recycle, is part of sustainability policies in urban planning, based on the enhancement of local resources. The Observatory Lab Pay(s)age, is intended as a structure for site-specific study and continuous fieldwork, concerning both the evolutionary processes of natural structures and the involution of built environment. Starting from these materials, many different regeneration methodologies and temporalities have been imagined. Following the logic promoted by the ELC, the work has started by monitoring some specific areas and by contacting different local representatives with the aim of collecting data and experiences to construct a shared knowledge of the places. Then the project has become an on-going tool including all phases in the regeneration process: observation, analysis, interpretation and re-launch of new hypothesis are fundamental elements to increase the public knowledge about the cultural factors characterizing the landscape discipline. Thus, the notion of « observatory » is a strategic device, monitoring the evolution of places in time through actions of dialogue and awareness raising, in order to get citizens re-acquire a consciousness of their territory. The collected qualitative data, describe the peculiar features of the sites, based on the local actors experience and knowledge. These elements are the basis for new scenarios, used as progressive steps leading the recovery process. For this reason, the « observatory » is also a « laboratory », as the experimental projects accompany the transformation of the places through intermediate phases. Understanding and accepting mutability as a character of landscape is a preliminary step towards a co-action, where the project accords with natural dynamics. Lab Pay(s)age, according to the ELC principles, is using the earliest local answers as re-launch factors for consecutive projects, taking into account the territorial temporalities as priority in transformation process. The presentation concerns the ongoing projects and obtained reactions, such as the earliest re-naturalization programs, some selected sites for monitoring activities and Phd researches on new regeneration methods using vegetation as an active element in reclamation of industrial sites. 1 Occhiuto, R. 2016.

This presentation focuses on multiple-choice items without any correction or control for guessing. Most often, item responses are recoded as binary outcomes so that dichotomous logistic item response models (such as the 2PL or 3PL models) can be used to estimate ability levels. This is however at the cost of loosing information from collapsing all distractors into a single FALSE category. Polytomous IRT models could be considered to overcome that drawback but none of the classical models are suitable to incorporate guessing into account. The purpose of this talk is to introduce a modification to the graded response model (Samejima, 1969) that can take guessing into account. The modification consists in introducing lower and upper asymptotes to the cumulative probability curves. After a brief theoretical and technical description, practical implementation using the R package mirt (Chalmers, 2012) is discussed. Primary results from a simulation study are eventually presented and compared to traditional IRT scoring methods for scoring multiple-choice items. [less ▲]

Bacterial peptidoglycan-derived peptides and muropeptides are soluble unique fragments acting as messengers in diverse cell-signalling events. As the bacterial peptidoglycan wall is a major target of antibiotics, bacteria have developed specific resistance mechanisms based on the detection of such fragments. In addition, the muropeptides sensing is involved in the innate immune response toward bacterial invasion and is therefore of major importance in the eukaryotes self-defence functions. In Bacillus licheniformis 749/I, the peptidoglycan dipeptide m-A2pm-D-Glu triggers beta-lactam resistance via the induction of a beta-lactamase, BlaP. This induction process relies on a complex regulation system for which the nature and the concentration of peptidoglycan fragments leading to the formation of dipeptide moiety inside the cytoplasm are unknown. In this context, the development and the validation of a reliable method to identify and quantify those cytoplasmic fragments is of major interest. Conventionally, the peptidoglycan is first digested by mutanolysin in order to generate muropeptides which are subsequently analyzed by reversed-phase liquid chromatography (RP-LC, C18). However, this technique is not effective enough to separate the peptides that, as a result, are eluted in the flow through . In this work, we developed two novel analytical separation methods, namely capillary electrophoresis (CE) and zwitterionic hydrophilic interaction liquid chromatography (ZIC-HILIC) both coupled to mass spectrometry (MS), aiming at overcoming the drawbacks encountered in traditional separation techniques. Both methods show great results in the identification of peptidoglycan fragments in complex samples. CE analysis lead to muropeptides and peptides separation whereas ZIC-HILIC only retains peptides. Nevertheless, the latter has been optimized and validated for the cytoplasmic peptidoglycan peptides identification and quantification. Althogether, ZIC-HILIC-MS and CE-MS have proved to be powerful analytical tools for the identification and quantification of peptidoglycan fragments in complex matrix samples. Further optimizations are still ongoing for the analysis of muropeptides, which hopefully will lead to the identification and quantification of cytoplasmic peptidoglycan fragments composition during the Bacillus licheniformis 749/I BlaP beta-lactamase induction process.

Dans son ouvrage bien connu consacré au « Latin de Polybe », M. Dubuisson s’efforça de relever de façon exhaustive les traits de langue qui trahissaient l’influence du latin chez l’historien grec. Mais au-delà, il s’agissait également de tirer toutes les conséquences historiques des conclusions tirées de l’analyse philologique, afin de mieux comprendre l’œuvre de Polybe. M. Dubuisson fut ainsi l’un des promoteurs d’une approche plus qualitative du bilinguisme gréco-latin, approche qu’il élargit ensuite à d’autres champs d’étude. Ce faisant, il contribua à l’affinement de nos connaissances sur les rapports que Rome entretenait avec la Grèce et sa langue, et vice-versa. Et sa démarche fut féconde, tant à l’Université de Liège, où elle s’enracinait dans une tradition solide, qu’à l’extérieur. [less ▲]

En 1916, l’archéologue Vittorio di Cicco entreprenait des fouilles sur le site de la « Vigna Manzi », à Garaguso, en Basilicate. Il y découvrit les vestiges d’un temple qui contenait encore une partie de son mobilier et différentes offrandes dont la statuette en marbre d’une déesse trônante accompagnée d’un tempietto. Cette découverte ramenait à la lumière un site de premier ordre pour l’étude des relations qu’entretenaient, dans ces territoires d’Italie méridionale, les populations indigènes et les Grecs des cités de Grande Grèce. Dans le courant du XXe siècle, d’autres fouilles se sont succédé dans le sanctuaire de la « Vigna Manzi » – sans grand résultat. Durant l’été 2008, l’archéologue Jean-Marc Moret a cherché à identifier l’emplacement de la fouille de Vittorio di Cicco. Ce sondage lui a permis de retrouver d’autres structures monumentales augurant une découverte d’envergure. La publication de cette entreprise a ensuite été confiée à Thomas Morard, professeur à l’Université de Liège. Dans cette perspective, une campagne de documentation a été menée durant l’automne 2016. S’en suivra la reprise de l’enquête de terrain, un nouveau projet archéologique pour l’Université de Liège [less ▲]

La première, intitulée Conversation à « La Cathédrale » (1973), est l'œuvre de Sylvie Léger et Bernard Sesé ; la deuxième, Conversation à La Catedral (2015), est signée Albert Bensoussan et Anne-Marie Casès. Notre analyse porte tant sur l'« épitexte » — en particulier, sur les essais d'Albert Bensoussan à propos son travail de traducteur — que sur le « péritexte » (Genette). Ces éléments fournissent en effet de précieuses informations, non seulement pour déterminer la stratégie globale adoptée par les traducteurs par rapport au texte source, mais aussi pour observer l'évolution des « normes de traduction » (Toury) à l'œuvre dans chacune des versions françaises. Les notes du traducteur, notamment, soulèvent les questions de l'implicite et de l'explicite, des connaissances supposées du lecteur cible et de la visibilité du traducteur. [less ▲]

Today, anthropogenic pressures are posing major challenges to Asian primates, forced either to adapt ecologically and behaviourally to the human massive encroachment into natural habitats, or to disappear. Species ability to survive in human-modified habitats greatly varies, with generalist species, such as Cercopithecines, being more likely to thrive. Several macaque species in particular proliferate in situations of commensal association with humans, which leads sometimes to local overpopulation. High density of primates, resulting from the combined effect of population spatial compression and positive demographics, systematically induces conflicts with humans over crop-raiding and nuisance issues. Different management strategies have been deployed these last decades, going from culling or trapping programmes to sterilization campaigns. Sterilization is an ethical and flourishing solution to mitigate the human-macaque conflict by limiting the population expansion, but very few empirical data are available about their efficiency and potential side effects. We propose here to review various macaque sterilization programmes conducted in Asia, highlighting the pros and cons as well as the short- and long-term effects. As a study case, we will present data on population dynamics and side behavioural effects, as the base for an ongoing sterilization programme in a population of long-tailed macaques (M. fascicularis) in Bali (Indonesia). This population has experienced a tenfold increase over the last 30 years. Vasectomy undergone by several males in a former approach was not efficient to limit births. With others, we argue that macaque’s reproductive profile requires female sterilization. The goal here is to stimulate discussion over management of forced coexistence scenarios between human and primates, since this phenomenon is an integrative part of conservation in this rapidly changing world.
