Introduction: Spectroscopic and polarimetric observations are of fundamental importance in order to derive information about the surface properties of asteroids. In 2006, the asteroid (234) Barbara was found to possess a pecular polarimetric response characterized by an abnormaly large value of the inversion angle. Later on, several other similar asteroids were discovered. They were called Barbarian asteroids in reference to (234) Barbara. Spectroscopically, all the Barbarian asteroids belong to the L, Ld and in a few cases K types in the Bus and Binzel visible taxonomy. When a classification extended to near-infrared is considered, all those known to date group into the L class. The most commonly accepted explanation for the polarimetric anomaly is the high abundance of Spinel-bearing, fluffy (type A) CAIs (Calcium-Aluminium rich Inclusion) whose optical properties could reproduce the observed polarimetry. If this hypothesis is confirmed, Barbarian asteroids could contain an anomalous amount of the first minerals condensed after the formation of the Solar system. Based on these motivations, we organized a systematic campaign of spectroscopy and polarimetry of Barbarians/L-type asteroids. Observations: 35 asteroids were observed using spectroscopy or polarimetry, or both. These asteroids include members of Watsonia, Henan and Klumpkea families which are known to be made of Barbarian and/or L type asteroids. The polarimetric data were obtained with the ToPol instrument at the Calern station of the Observatoire de la Côte d’Azur. The spectroscopic data were obtained at the IRTF NASA facility. Data analysis: The phase-polarization curve of the polarimetric data was analysed to derive the inversion angle of the asteroids. The spectroscopic data were analysed using a Hapke spectral mixing model. This method combines end-member spectra in order to fit the asteroid spectrum and derive its composition. The end-members used are the Allende matrix from which CAIs were removed, MgO rich olivine, and fluffy type A CAI. A Hapke space-weathering model was used in order to simulate the space-weathering effect on the spectra of asteroids. Results: The polarimetric data allowed us to discover 3 new Barbarian asteroids and to remove 4 asteroids from the Barbarian candidate list. We found that the inversion angle of Barbarian asteroids ranges from 26° to 30°. High CAI abundances ranging from 5 to 50% were found in L type asteroid spectra. We find for the first time a link between the abundance of CAIs and the polarimetric response. Spaceweathering also appears to play a role in polarimetry, showing an aging effect on the granularity of the surface regolith. [less ▲]

Writer-musicians in translation, or how to deal with artistic hybridity? The case of Leonard Cohen. Amazon.com is just one of the many websites that has a separate category for writer-musicians in its books section: singers who are also authors – or vice versa. Leonard Cohen, Patti Smith, Ry Cooder, Nick Cave and Bob Dylan are just a few examples, and while they tend to be known and recognised as musicians, their literary works are generally well-received and translated into a number of languages. To what extent are the different mediums treated differently; are separate translation strategies employed; do literary and musical institutions elbow each other out the way when it comes to the reception and creation of a translation? Leonard Cohen is an example par excellence. France saw not only his (complete) literary works translated into French, but also many of his albums. That is notable, as Susam-Saraeva has previously argued that popular music is generally not translated. Using a discourse analysis of reviews and critical writings on Cohen in the French media (Rock et Folk, Pop Music, Extra, etc.) from the early 1970 (which was when his career as a singer truly skyrocketed in France and the rest of Western Europe), I will determine which arguments were used to justify both the initiative to translate his work as well as the various translation strategies (Franzon 2008). This line of argumentation is then compared with a number of other translations. For some songs – which were often first released as poems – there were even different translations in circulation. Secondly, I shall compare these findings to a more recent body of work – the reception and translation of his collection of poems, Book of Longing (2006) [Le Livre du Désir] and the album Ten New Songs (2001). The album was a compilation of a selection of poems from Book of Longing that Cohen set to music. In France all the lyrics were translated and included on the album’s insert. Using this quasi-simultaneous double-translation, I shall assess how the same text was translated and received in the musical and literary systems (in France) and whether the politics of translation with respect to Cohen’s work has changed over the years.

Based on a corpus of texts that are used to teach seminars in translation into the foreign language, the present paper argues that for future translators good reading skills are almost as important as high-level proficiency in both languages. The corpus comprises texts that share a common topic (travelling) but differ in terms of genre, so that the specific characteristics of each text can be described in relation to the other component texts rather than to abstract text types included in text typologies. The exercises in the seminars, before actually starting to translate, aimed at reading a text at different levels, i.e. the text as a whole, its discursive dynamics, and its component parts, while trying to connect it to the other texts included in the corpus. The preparatory exploration of the source text as well as the actual process of translation can be conceptualized as the Game of the Goose (or Snakes and Ladders): translators have to find their way through the text, taking advantage from short cuts and anticipating pitfalls they already know from past experiences.

The last eruption of Mt Fuji (Japan) occurred in A.D. 1707. The eruption lasted 16 days from 16 December 1707 to 1 January 1708 (Tsuya, 1955) and 1.8 km3 of volcanic materials were ejected in total (Miyaji et al., 2011). Lake Yamanaka, a very shallow lake (max. 14. 3 m depth) located at the foot of the east-north-eastern flank of Mt Fuji, was heavily impacted by the eruption. A thick scoria layer entirely covered the catchment of Lake Yamanaka. The thickness of the deposit varies from 5 to 37 cm around Lake Yamanaka and reaches up to 149 cm at the south-west extremity of the catchment (Miyaji et al., 2011). In order to study the influence of Hoei eruption on Lake Yamanaka, 5 gravity cores were taken during the 2014 QuakeRecNankai campaign. The Hoei scoria was present at the bottom of the one core and in the core catcher of the four other cores. High resolution magnetic susceptibility, XRD, XRF, LOI, C/N and 210Pb/137Cs analyses were performed on the gravity cores. The results shows three distinct periods of sedimentation: (1) From Hoei eruption to A.D. 1900; (2) From A.D. 1900 to A.D. 1990; (3) From A.D. 1990 to A.D. 2014. The first period is characterized by a very low sedimentation rate (~0.07 cm/yr). During this period, the sediments of the catchment were trapped below the thick Hoei scoria layer. However, peaks of terrigenous input are recorded. We link such detrical signals with violent typhoons that hit the Fuji Five Lakes region. The water from the heavy rains percolated through the porous thick scoria layer and saturated it. As a result, surface runoffs carried the sediments from the catchment into Lake Yamanaka. The second period (from A.D. 1900 to A.D. 1990) is defined by an increase of the sedimentation rate (~0.16 cm/yr). The development of soil and the agriculture (e.g. pastureland, rice field, mulberry plantations) reduced the impact of Hoei scoria. The terrigenous inputs are higher than previously but remained more or less constant during this period of time. As the thickness of the scoria layer is partially reduced or covered by new soil, rains triggered by smaller typhoons could drain the sediments from watershed and transport them into the lake. The most recent period representing the last 27 years is characterized by a very high sedimentation rate (~1.036 cm/yr). The transition between period 2 and period 3 corresponds to the development of mass tourism and the urbanization around Lake Yamanaka. It is marked by an increasing of atmospheric pollution (Pb, Zn). In the upper part of the cores, a peak of 137Cs is observed. Such peak is related to cesium fall-out after Fukushima incident in 2011. In addition to the fingerprint of human impact, the lake also record a terrigenous signal related to the 2007 Fitow typhoon which provoked damage in the area. This study highlights the influence of eruptions and typhoons on the sedimentation of Lake Yamanaka. In the present day, the sedimentation recovery after a major eruption is accelerated by human activity. References: Miyaji N., Kan'no A., Kanamaru T., Mannen K. 2011.

Human mobility affects land use and human density distribution. Unfortunately, this rarely takes into account the real and potential changes induced by hazards on the natural systems. Thus, migration and natural hazards should be constantly analyzed through cross-sectional and global studies to reduce disastrous consequences resulting from their mutual interactions. In a multi-risk and demographic sprawl context, the study focused on the cross-analysis of human density and natural hazards in Bujumbura. The results show that migration of people should ideally be guided by knowledge of the area's sensitivity to natural hazards, taking into account other parameters such as hazards susceptibility maps and production opportunities. While the migration of people toward overcrowded centers constitutes a big challenge, it is an important asset when it concerns areas in need of manpower. It also allows the balance in relieving saturated areas, reducing human pressure on the environment. Therefore, there is a need that policymakers comply with those aspects, finding the right balance for a better situation. [less ▲]

Damit die Lernenden als zukünftige verantwortliche Bürger eine authentische Vision der Wissenschaft und ihrer Grenzen gewinnen, heben die Rahmen- und Lehrpläne immer mehr die Notwendigkeit hervor, sie mit wissenschaftlichen Modellen und derer Erarbeitung vertraulich zu machen. Die chemische Kinetik bietet einen günstigen Rahmen, solche Modellierungskompetenzen zu fördern. Das didaktische Ziel kann wie folgt zusammengefasst werden: Eine chemische Reaktion als das Resultat wirksamer Stöße zwischen Molekülen beschreiben, um den Einfluss verschiedener experimenteller Faktoren auf die Reaktionsgeschwindigkeit zu erklären. Dies verlangt eine Modellierung, bei der die vier Ebenen (empirisch, makroskopisch, symbolisch, mikroskopisch) des didaktischen Tetraeders von Kermen und Méheut (2009) (Chemistry Education Research and Practice, 10, 24-34) erörtert werden. In diesem Vortrag werden verschiedene Aktivitäten (z.B. Versuche über molekulare Diffusion, Einführung des Begriffes des Übergangszustandes anhand angepasster, selbstgebauter Molekülmodelle) präsentiert und didaktisch ausgewertet. Großes Gewicht wird darauf gelegt, dass die Lernenden sich der erklärenden Rolle der Modelle bewusst werden, dass ihre Autonomie gefördert wird, indem der Schwierigkeitsgrad der sogenannten Zone der nächsten Entwicklung (Wygotski) entspricht, und dass das vorgestellte didaktische Modellierungsverfahren die Denkweise der Wissenschaftler reflektiert.

The existing literature in fire engineering is mostly based on single component study of structures, as opposed to system level building performance. In current practice, fire does not need to be considered as part of the structural design of the building. The required fire protection for steel components in a building is based on prescriptive design guidelines, which are based on standard fire tests on individual structural members. In addition, the fire-structure engineering has primary focused on deterministic analysis, while the field is moving towards performance-based design in recent years. Meanwhile, the scenarios leading to a fire event and the performance of the structure at elevated temperatures involve a great level of uncertainty. This work focuses on fire-structure interaction with the objective of developing fire fragility functions that capture fire damage uncertainty for the entire building (i.e., at the system-level). A fragility function provides the probability of exceeding a damage state for a given intensity measure of a given hazard. Fire fragility functions can be developed to measure the expected losses based on performance of a building structural system, rather than a single component. Different functions can be developed for buildings with different typologies (e.g. high-rise steel building with moment resisting frame, low rise steel building with bracing). This presentation derives fragility functions based on stochastic analyses of prototype buildings. In developing the fragility functions, uncertainties in the fire model, the heat transfer model and the thermo-mechanical response should be considered; but such a large number of random variables adds to the complexity of analysis and the computational time. Based on a sensitivity analysis for steel gravity frames, this work identifies the most important input parameters to be considered as random variables when developing fire fragility functions for an entire building. The sensitivity analysis for a multi-story steel building prototype is completed considering uncertainties at the compartment and building levels. At the compartment level, uncertainty in the fire scenario, compartment geometry, applied load, thermal and mechanical properties of steel and insulating materials are considered. At the building level, the influence of fire-resistance rating, building height, and occupancy type are studied. The results of this study identify the local and global parameters needed as part of deriving system-level fire fragility functions for a steel building. [less ▲]

This paper aims at building a critical reflection on the valuation of design experimentation in architectural research and its impact on knowledge production. These considerations are rooted in the observation of a hybrid and prospective research experience led at the University of Liège (Revisiting the apartment building 2015-2016), combining documentary research, field investigation, and a research-by-design international design studio gathering 40 architects and students in architecture. We first position the essay on the issue of harnessing design activity for the benefit of architectural research. Secondly we report on the investigation observed and the distinct knowledge production modalities involved in the project. The particular implication of the act of designing is highlighted, among other steps of the investigation, and we put forward some characteristic features of the research process. We particularly consider the different design techniques, tools and representational processes involved in four distinct architectural experimentations and their impact in the emergence of design strategies or spatial interventions. We finally open a discussion on the questions raised by the valuation of these proposals in the research, and stress the inherent tension between opening new perspectives and redefining the scope of inquiry.

Covering problems are traditional issues in mathematics. For instance, a natural covering problem in the n-dimensional euclidean space is to ask for the minimal number of identical spheres needed to cover a large volume. The same issues can be considered in graphs. The corresponding covering problem is to determine the minimal number of r-balls that can be placed in such a way that every vertex of the graph is contained in at least one of them. In this talk, we consider coverings that satisfy special multiplicity conditions, called (r,a,b)-covering codes. These codes generalizes the notion of perfect codes in graphs that correspond to tilings of the graph with r-balls. We focus our attention on the multidimensional infinite grid and discuss the periodicity of (r,a,b)-codes in this case. Finally, for the dimension 2, we determine the possible values of the constant a and b. [less ▲]

Sever fires in buildings can lead to local failures, instability, partial or total collapse of the structure. In majority of the times, fire is a secondary event, after blast or impact, while the building has experienced some damage. Examples of widely known events include the 1968 Ronan Point collapse in the UK, the 1995 Oklahoma City bombing, the World Trade Center Collapse in New York in 2001, the 2014 collapse of a building at New York’s Harlem neighborhood due to a gas explosion, and the recent 2015 collapse of a building at New York’s East Village also due to a gas explosion. The initial shock to the building can be conservatively modeled by removing an intermediate vertical supporting element (i.e. loss of load-carrying capacity in a critical element), leading to an increased span for composite floor slabs. In a lowrise building, if there is enough reinforcement throughout the slab and enough continuity and restraint, despite large deflections that will develop, the slab is capable of carrying the loads by membrane action. Fundamentally, the floor system behaves as an inverted dome structure with radial tensile forces and a compressive hoop stresses. This holds true at ambient temperature, yet a similar resisting mechanism forms during fire. Previous research and experimental work shows that fire performance of composite floor slabs can be used to reduce the fire protection requirement of the steel elements, i.e. the designer should take advantage of reserve capacity in the composite floor slab membrane action. The utilization of membrane action in the design of composite floor slabs has been used, to some extent, for mitigating collapse from single events (blast or fire only). Given that, often the initial blast is followed by a secondary fire event, this work investigates the system-level performance of low-rise damaged buildings subject to post-blast fires. The hypothesis is that, when incorporated in the design, low-rise buildings can withstand the post-blast fires through membrane action of composite floor slabs. Application of this concept, within a performance-based framework, can be used to avoid progressive collapse, or at the minimum increase fire resistance to allow for safe evacuation. This work investigates the design requirements for beam sizes, fire protection, concrete reinforcement and cover thickness to develop membrane action for a pre-defined fire resistance rating under cascading post-blast fires.

In the last fifteen years, Belgian prisons have been characterized by an increase of managerial and legal regulations. This rise of “inscribed knowledge” (Freeman & Sturdy, 2015) however leads to a sharper need of prison governors for “practical wisdom” (Chia and Holt, 2009). Firstly, because law and policy don't apply automatically, but must always be interpreted by human actors in relation to the situation. Secondly, because the increase of legal and managerial inscriptions reinforces prison governors’ more general inclinations to “satisficing” decisions (March and Simon, 1958). Drawing on four years of qualitative research with 40 Belgian prison governors, this empirically based paper analyses how they cope with complex, uncertain and ambiguous situations where neither epistemic nor technical knowledge is available. In doing so, we assume that they – at least marginally – “enact” prison organisations and prison policy (Weick, 1988). [less ▲]

Revenant sur les appels à la « fierté collective », au « patriotisme économique » et au « nationalisme d’ouverture » réitérés par les derniers Ministres-Présidents à la tête de la Wallonie, la communication s’attache à montrer comment ces tentatives de revitalisation d’un sentiment d’attachement identitaire, tout en relevant des manifestations du « nationalisme banal » (M. Billig), entretiennent le déficit d’imaginaire régional, réduit au développement de la « marque Wallonie » et de sa promotion auprès de ses habitants et des investisseurs. L’insistance sur la seule valeur économique et instrumentale de la communauté, visant à améliorer la compétitivité de la région sur son marché global et intérieur, fait d’autant mieux ressortir, par contraste, la dimension narrative sous-jacente à l’imagination nationaliste, particulièrement mise en évidence dans la nouvelle économie de l’enrichissement (L. Boltanski et A. Esquerre), fondée sur la patrimonialisation et l’exploitation du passé comme gisement de valeur. Du croisement des deux axes ainsi dégagés (nationalisme de faible ou forte intensité ; recours plus ou moins appuyé au storytelling), émerge une conception élargie du nationalisme, qui en fait apparaître de nouvelles modalités et permet d’ouvrir à une autre compréhension de doctrines comme le national-libéralisme ou le projet post-national. Dans la continuité des observations de M. Billig, notre cadre d'analyse structurale tend à faire des mouvements nationalistes (au sens le plus courant du terme dans l’analyse politique) un simple cas particulier parmi d’autres modes de participation plus ordinaires, infra-conscientes et naturalisées, à la communauté nationale.

Background For the documentation of the clinical data, the International Classification of Primary Care (ICPC-2) is used, often in conjunction with the more granular International Classification of Diseases (ICD). For retrieval of scientific bibliographic information in GP/FM, Medical Subject Headings (MeSH) are used. With over 25,000 available MeSH descriptors, indexing is not easy, and yet not all aspects of the broad field of GM/FM are covered . ICPC-2 has been developed to identify reasons for encounter, symptoms, acts performed or requested and diagnosis in daily practice: It captures clinical encounters for epidemiological research. But, it was not constructed to reflect the non-clinical aspects of the profession, such as organizational, managerial, educational, and investigational aspects. Recently, a new taxonomy of organizational aspect of GM/FM has been developed to ameliorate this situation. The purpose of this development was to provide tools to exploit modern technology in terminology for information storage and retrieval systems , such as machine learning, semantic web techniques and natural language processing (NLP). The 182 concepts identified were thoroughly described in terminology records, which are freely accessible on the web (www.hetop.eu/Q). All concept and definitions were translated into 8 languages and are available online. (http://3cgp.woncaeurope.org). A book is available in 6 languages To develop the Q-codes 1700 abstracts of GP/FM congresses have been carefully analyzed. This has been the basis of the work.

L’appel au peuple contre des élites (politiques, économiques,…) constitue le cœur de la rhétorique populiste. Cependant, cette invocation du peuple, des hommes de la rue, des citoyens ordinaires n’est pas un acte strictement populiste. En effet, si la démocratie peut se définir, entre autre, comme le pouvoir au peuple, n’induit-elle pas alors un nécessaires recours à sa mobilisation ? Comment distinguer l’appel au peuple du discours populiste, d’un discours démocratique ? Plus précisément, comment pouvons-nous définir le peuple ? Et quels sont les enjeux politiques et idéologiques qui sous-tendent sa mobilisation dans la rhétorique populiste ? Pour répondre à cette interrogation, nous proposons, dans un premier temps, en nous appuyant sur la littérature scientifique, de clarifier la notion de peuple et de populisme. Dans un second temps, nous étudierons le discours politique du Front national français tout en mobilisant les apports théoriques précédemment analysés. Pour ce faire, nous concentrerons notre attention sur le programme du parti, les communications orales de ses principaux représentants ainsi que les différents éditoriaux publiés sur leurs sites internet. L’analyse est discursive. En guise de conclusion, nous reviendrons sur la classification du Front national en tant que parti populiste tout en essayant de dégager les points communs et les divergences que nous pouvons observer entre la notion de peuple telle que définie par la littérature scientifique sur la démocratie, le populisme et dans les discours du FN. À terme, nous espérons ainsi mieux comprendre la notion de peuple dans l’argumentaire frontiste ainsi que ses différents éléments constituants. [less ▲]

Food is often source of conflict between humans and wildlife in Gabon with elephants being the worst crop-raiders and “problem animals”. Damages to crops drastically reduce income, amplifying poverty and creating a negative perception of wild animals among rural people. Using beehives has been proposed as one of the best non-lethal methods to deter elephants from crop raiding; so we experienced whether the presence of the African honey bees species Apis mellifera adansonii deterred forest elephants (Loxodonta Africana cyclotis) from feeding on fruit trees on the one hand and if local people could perform modern beekeeping. We found that beehives can be effective deterrents of crop raiding by elephants, but rural people must actively manage hives to keep them at the optimum activity level. Most interestingly, modern beekeeping benefits wild bees preservation (because local people destroy them to collect honey), agriculture through pollination and could be effectively used as a bush-meat trade alternative. We learned from those experiences that conservation is performed and assumed daily by people sharing spaces and resources with wildlife. For that we need to transfer knowledge and capacities to them in order to achieve effective long lasting conservation outcomes. We also must go beyond aspirin (symptomatic) treatments by investigating elephant crop raiding root causes with multidisciplinary ecophysiological approaches. In animals ecophysiology examines the relevance of physiological processes to social, behavioural and ecological constraints with an eco-centric view. Thus, they will help get better understanding of what lead elephant to face threats such as bees or what could explain nutritional behavior and crop selection of elephants. [less ▲]

Cette contribution porte un intérêt singulier à la construction de l’action publique par les intermédiaires privés et publics de l’emploi, au travers de leur mission d’accompagnement des demandeurs d’emploi. Elle porte sur l’analyse des tensions intra professionnelles qui résultent de la mise en oeuvre d’une politique d’activation, dans un contexte de gestion mixte du marché du travail, en Belgique francophone. Elle prend pour objet l’accompagnement des demandeurs d’emploi, en tant que mesure destinée à assurer la réinsertion socioprofessionnelle des demandeurs d’emploi par une lutte contre le chômage de longue durée et l’exclusion sociale (Orianne, 2006). Elle s’appuie sur recherche empirique de nature qualitative (N=233 séquences d’observation ; N=40 entretiens semi-directifs), effectuée entre janvier 2013 et juin 2014 en Fédération Wallonie-Bruxelles auprès du service public régional de l’emploi Bruxellois et d’un prestataire privé. Face à la nécessité croissante de fournir des services à un marché du travail flexible et en évolution constante, d’impérieux besoins de transparence et de modernisation des services publics de l’emploi belges sont apparus. Cette transformation de l’action publique s’est notamment apparentée à une décentralisation partielle de leurs ressources et de leurs responsabilités auprès de partenaires privés (agences d’emploi privées commerciales ou opérateurs non-marchands) afin d’assurer conjointement la réinsertion socioprofessionnelle des demandeurs d’emploi par la dispense d’un accompagnement ciblé et personnalisé (Aubert et Patry, 2004). Par cette collaboration, les opérateurs privés participent désormais activement à la construction de l’action publique par le pouvoir qu’ils détiennent via l’exercice – par délégation – des fonctions étatiques alors que jusque dans les années 80, l’État orientait, contrôlait et assurait seul la régulation du marché du travail (Muller et Surel, 1998). En échange, tant les services publics de l’emploi que les prestataires privés sont amenés, dans le cadre de leurs activités d’accompagnement, à devoir rendre des comptes sur la réalisation effective de leurs pratiques. Cette exigence d’accountability comporte un double but : être transparent et légitimer l’utilisation de l’argent public. S’inscrivant dans une sociologie de l’action publique, cette contribution tend à rendre compte que cette forme de gouvernance de l’action publique (Lascoumes et Le Galès, 2012 ; Yaya, 2005) repose sur une gestion par les procédures et sur une pression aux résultats, transformant dès lors le travail quotidien des intermédiaires de l’emploi sous couvert d’une rationalisation de l’action publique. Ce faisant, elle démontre la présence d’un conflit entre l’implémentation d’une mesure d’activation et l’évaluation de son efficacité par les pouvoirs publics. [less ▲]

Background: GPR101 is an orphan G protein-coupled receptor (GPCR) that is duplicated in patients with X-linked acrogigantism (X-LAG) and over-expressed in their GH- and PRL-secreting tumors. GPR101 is a constitutively active GPCR that strongly activates the cAMP pathway. To elucidate the mechanisms through which GPR101 causes GH over-secretion we generated HEK293 and GH/PRL-secreting (GH3) cells with stable GPR101 expression. Methods: Both cell lines were created via direct integration of a human GPR101-coding sequence into their genome. In HEK293 cells this was achieved by transient transfection of a GPR101-expressing plasmid, while GH3 were transduced with GPR101 lentiviral particles. Cells were selected with appropriate antibiotics and the surviving clones expanded. GPR101 expression was quantified by RT-qPCR and immunofluorescence/western blotting. Cell proliferation (MTT assay), cAMP levels (125I-labeled cAMP tracer), and calcium signaling (FURA 2 AM) were determined. RNA was extracted from both cell lines and subjected to RNA-seq. Differential gene expression between control and GPR101-expressing cells and pathway analysis was carried out with the Stirplate and MetaCore softwares, respectively. De-regulated genes were validated by RT-qPCR. Results: High GPR101 expression was achieved in both cell lines and confirmed at the mRNA and protein level. GPR101-expressing cells proliferated at different rates from the respective controls: GPR101-HEK293 cells were slow-dividing, while GPR101-GH3 divided faster. cAMP production was enhanced in GPR101-GH3 and accompained by increased excitability of cells. Differential expression analysis in HEK293 cells revealed several up-regulated and few down-regulated genes. Among the genes with high expression, several were linked to the cAMP pathway: CGA, PCK1, LINC00473 and PDE3A. Enrichment analysis ranked cytoskeleton remodeling and cell cycle regulation (inhibition of G1/S transition) as the most relevant pathways. In GH3 cells most of the genes with a significantly different expression encoded for membrane-localized proteins, among which were ion channels (Trpm8, Kcnj1), GPCRs (Trhr), and calcium sensors (Syt4, Anxa1). Biological processes associated with these genes are: vesicle transport and fusion, cytoskeleton organization, and energy homeostasis. Conclusions: These results show that the intrinsic activity of GPR101 strongly stimulates cAMP production and this in turn facilitates voltage-gated calcium influx. Changes in cAMP/calcium signaling are accompanied with faster/slower cell division depending on the cell type. Accordingly, several genes associated with these and related pathways are differentially expressed. The establishment of these cell lines will be of paramount importance to validate putative GPR101 ligands and to conduct functional studies. [less ▲]

The intense ultraviolet auroral emissions of Jupiter are currently being monitored in the frame of a large Hubble Space Telescope (HST) program meant to support the NASA Juno prime mission. The present study addresses the three first Juno orbits (PJ03, 04 and 05) during which HST obtained parallel observations. These three campaigns basically consist of a 2-week period bracketing the time of Juno’s closest approach of Jupiter (CA). At least one HST visit is scheduled every day during the week before and the week following CA. During the ∼12-hour period centered on CA and depending on observing constraints, several HST visits are programmed in order to obtain as many simultaneous observations with Juno-UVS as possible. In addition, at least one HST visit is obtained near Juno’s apojove, when UVS is continuously monitoring Jupiter’s global auroral power, without spatial resolution, for about 12 hours. We are using the Space Telescope Imaging Spectrograph (STIS) in time-tag mode in order to provide spatially resolved movies of Jupiter’s highly dynamic aurora with timescales ranging from seconds to several days. We discuss the preliminary exploitation of the HST data and present these results in such a way as to provide a global magnetospheric context for the different Juno instruments studying Jupiter’s magnetosphere, as well as for the numerous ground based and space based observatories participating to the Juno mission.

Het domein van de zorg voor geïnterneerde personen kent internationaal een omslag. Naast de “criminalisering” van personen met een psychiatrische stoornis die criminele feiten begaan, ontwikkelen er zich nieuwe visies en zorgperspectieven op de kwaliteit van leven en de re-integratie in de maatschappij van zowel personen met psychische kwetsbaarheid als geïnterneerde personen.1 Tot zeer recent werden geïnterneerde personen bijna exclusief benaderd als personen die misdaden of misdrijven hebben gepleegd waar ze door hun psychische stoornis niet voor verantwoordelijk konden worden gesteld. De onderliggende logica van de aanpak was sterk geënt op een model waarbij opsluiting en isolatie van de maatschappij centraal stonden omwille van misdaad. Geïnterneerde personen werden om die reden opgesloten in een gevangenissysteem volgens een justitiële benadering. Het behandelings- en zorgperspectief raakte hierbij ondergesneeuwd. De “criminalisering” van personen met psychische stoornissen heeft in België historisch geleid tot inadequate aanpak en begeleiding van deze groep patiënten. Meerdere veroordelingen van de Belgische Staat door het Europees Hof voor de Rechten van de Mens (EHRM), overvolle gevangenissen, het gebrek aan somatische en psychiatrische gezondheidszorg binnen gevangenissen en psychiatrische annexen en aanbevelingen van het Europees Comité voor de Preventie van Foltering en Onmenselijke of Vernederende Behandeling of Bestraffing (CPT) zijn directe aanleidingen voor het Masterplan Internering (juni 2016)2 en de wet van 5 mei 2014 betreffende de internering van personen3.

Field data for validating hydraulic models remain scarce, They are often limited to inundation extents and water marks, which provide little insights into the dynamic features of the flow in urbanized floodplains, such as the discharge partition in-between the streets and the velocity fields. To address this issue, a unique experimental setup representing a whole urban district was built in the laboratory ICube in Strasbourg and the state-of-the-art shallow- water model Wolf 2D was tested against the experimental measurements (An'ault et al, 2016), The numerical model was also used to extend and refine the analysis of the laboratory observations. The experimental model (5 m >< 5 m) represents a square urban district with a total of l4 streets of different Widths and 49 intersections (crossroads). The inflow discharge can be controlled in each street individually and the outflow discharges were measured downstream of each street. The numerical model Wolf was developed at the University of Liege and has been extensively used in flood risk research (Beckers et al, 2013, Bruwier et al. 2015, Detrembleur et al. 2015). Several lessons could be learned from this combined experimental and numerical analysis. First, we found that the discharge partition in—between the streets is primarily controlled by the street widths. Second, although the standard shallow-water equations reproduce satisfactorily tnost of the flow characteristics, adding a turbulence model improves the prediction of the shape and length of the flow recirculations in the streets. Yet, this has little influence on the discharge partition because the computed recirculation widths are hardly affected by the turbulence model. The experiments and the numerical model also show that the water depths in the streets remain fairly constant in~between two intersections, while they drop suddenly downstream of each intersection as a result of complex flow interactions at the intersections. This hints that friction has little influence on the water depths obtained in the experiments. However, tailored numerical tests demonstrate that this is a direct consequence of the distorted nature of the experimental setup. Indeed, the ratio between the water depth and the street width is close to 1 in the experiments, while it would be at least one order of magnitude lower in real-world conditions, even for extreme floods. Finally, remote sensing data, such as digital elevation models, are generally available on a regular grid, which makes it convenient to use also a Cartesian grid for hydraulic modelling, We show here that the discretization of the geometry of the buildings on such a Cartesian grid has a major influence on the modelling accuracy (overestimation of the overall flow resistance). An extended shallow-water model based on non-isotropic porosity parameters is shown to improve substantially the prediction of the discharge partition in-between the streets. It is therefore considered as a valuable tool to advance urban flood modelling in practice. From the lessons learned here, we recommend that future research focuses on the design and exploitation of a less distorted experimental model, as well as on the analysis of extra flow processes such as transient conditions and interactions between overland flow and pressurized flow in underground passages.

Marine waters of semi-enclosed seas are affected by a major environmental issue which is oxygen depletion in bottom waters. Deoxygenation is one of the most widespread man-induced consequences which can be catastrophic for living species. Between 1970 and 1990, the benthic compartment of the Black Sea underwent modifications due to the occurrence and increase of hypoxia. Indeed, these changes might cause a deterioration of the structure and functioning of the ecosystems. Nowadays, some regions, such as the north-western shelf, are still affected seasonally by this phenomenon.Within the framework of the BENTHOX project, a biogeochemical study focusing on the early diagenesis is conducted in the Black Sea. It aims (1) to obtain a better understanding of the impact of benthic hypoxia on the diagenetic pathways, (2) to contribute to a new dataset of biogeochemical measurements in the sediments including porewaters. During a cruise (Emblas II – May 2016), on board the RV Mare Nigrum, sediment cores were taken at 4 stations on the Ukrainian shelf. Porewaters were extracted on board the ship using Rhizon technique under N2 atmosphere and will be analyzed for dissolved nutrients and major ions. In addition, sediments were sliced and will be determined for major solid phases and trace element contents. A multi-proxies (biological, sedimentological, mineralogical and geochemical) approach will be used to identify the hypoxic events and to reconstruct the history of bottom hypoxia. The results obtained will be presented and discussed with emphasis on the first outcomes and the major biogeochemical processes involved in the early diagenesis. [less ▲]

Juno obtained low altitude space environment measurements over Jupiter’s poles on 27 August 2016 and then again on 11 December 2016. Particle distributions were observed over the poles within the downward loss cones sufficient to power nominally observed auroral emissions and with the characteristic energies anticipated from remote spectroscopic ultra-violet auroral imaging. However, the character of the particle distributions apparently causing the most intense auroral emissions were very different from those that cause the most intense aurora at Earth and from those anticipated from prevailing models of magnetosphere-ionosphere coupling at Jupiter. The observations are highly suggestive of a predominance of a magnetic field-aligned stochastic acceleration of energetic auroral electrons rather than the more coherent acceleration processes anticipated. The Juno observations have similarities to observations observed at higher altitudes at Saturn by the Cassini mission suggesting that there may be some commonality between the magnetosphere-ionosphere couplings at these two giant planets. Here we present the Juno energetic particle observations, discuss their similarities and differences with published observations from Earth and Saturn, and deliberate on the implications of these finding for general understanding of magnetosphere-ionosphere coupling processes.

Most glaciers in Svalbard (High Arctic) have been retreating and thinning since the end of the Little Ice Age in the late 19th century. As a glacier retreats, it exposes new terrestrial habitats for the colonization by pioneering (micro)organisms. Here we report on the successional trajectories of cyanobacterial communities along a 100-year deglaciation gradient in the Ebba- and Hørbyebreen glacier forefields (Petunia Bay, central Svalbard). Cyanobacterial biomass and community composition were evaluated by epifluorescence microscopy and pyrosequencing of partial 16S rRNA gene sequences. Pseudanabaenales was the most abundant order in both forefields, followed by Chroococcales, Oscillatoriales, Synechococcales, Nostocales and Gloeobacterales. Succession was characterized by a decrease in phylotype richness and a marked turnover in community structure, resulting in a separation between initial (10–20 years since deglaciation), intermediate (30–50 years), and advanced (80–100 years) communities. Community turnover was explained by a combination of temporal and environmental factors, which accounted together for 46.9% of the variation in community structure. Interestingly, phylotypes associated with initial communities were related to potentially novel taxa (i.e. <97.5% similar to sequences currently available on GenBank) and sequences predominantly restricted to polar biotopes, suggesting that the initial colonization is performed by cyanobacteria from glacial and periglacial habitats. Advanced communities, on the other hand, included genotypes with a wider geographic distribution, which are likely able to establish only after the microenvironment has been modified by pioneering taxa.

Pliosaurids are iconic marine reptiles that dominated marine ecosystems during the Jurassic and the Cretaceous. These giant predators met their demise during the early Late Cretaceous but the final chapter of their long evolutionary history remains barely documented. Prompted by the discovery of a peculiar and very well preserved new taxon from Russia, we compute the evolution of pliosaurid disparity from their Early Jurassic radiation to their Late Cretaceous extinction. Despite a patchy Early Cretaceous fossil record, we show pliosaurids reached their maximal disparity during the Hauterivian-Barremian interval, suggesting a strong Early Cretaceous recovery from the apparently low phenotypic disparity of Late Jurassic pliosaurids. By using cladistic and ecomorphological data, we show that pliosaurids have repeatedly evolved slender-snouted polycotylid-like morphologies in each of their temporal radiations (Early Jurassic, Middle Jurassic and Early Cretaceous), demonstrating a more complex evolutionary history than their traditional representation as gigantic apex predators of Mesozoic marine ecosystems suggests. The extinction of pliosaurids during the Turonian (early Late Cretaceous) appears preceded by a late Early Cretaceous contraction of their disparity, the trajectory documented in ichthyosaurs, another successful marine reptile clade that disappeared during the Cenomanian-Turonian interval.

This study investigates the upper sediments infilling the central part of the Amik Basin in Southern Turkey. The Amik Basin is located in a tectonically active area: it is crossed by the Dead Sea Fault, a major neotectonic structure in the Middle East extending from the Red Sea in the South to the East Anatolian Fault Zone in the North. Continuous human occupation is attested since 6000-7000 BC in the Amik Basin. The study focuses on the sedimentary record of the Lake Amik occupying the central part of the Basin. Our objective is to constrain major paleo-environmental changes over the last 4000 years. The lake has been drained and progressively dried up since the mid-50s. The absence of water column during the summer season allows to collect lacustrine samples along a 5 meter depth trench with a sampling resolution of 1 to 2 cm. Diverse complementary methods were applied to characterize the sedimentary record: i.e. magnetic susceptibility, grain size, organic and inorganic matter by loss-of-ignition, mineralogy by X-ray diffraction and core scanner X-ray fluorescence (XRF) geochemistry. The age of the record is constrained combining radionuclide and radiocarbon datings. Structural disturbances observed in the lacustrine sediments record are linked with major historical earthquakes from the 6th to the 9th century AD due to the Hasipasa Fault rupture. In addition to the tectonic influence, the sedimentary record clearly shows two periods indicating strong soil erosion in the lake catchment: (1) the most recent erosion phase occurs over the Roman period to Present; (2) the oldest one would have occurred during the Late Bronze period. Such changes are most probably related to change in land use. In term of climate influences, the mineralogical and geochemical results allow to evidence variations in chemical weathering conditions in the watershed and lake water level fluctuations, respectively. The clay mineral assemblages attest for significant pedogenesis transformations, especially during the Islamic/Ottoman period. Based on XRF results, an increase in potassium is attributed to a lake development phase during a wet phase An overflow of the Orontes River would be responsible for clay deposition. By contrast, increased calcium and strontium rather correspond to a low lacustrine level and a drier period. The Bronze and Iron/Hellenistic periods are both characterized by low lake level with limited contribution from the watershed. To conclude, our multiproxy study of the Lake Amik allows to decipher between tectonic, human and climate influences over the last 4000 years. Further step would be to compare the Amik record with other regional archives to evidence local and regional events. [less ▲]

This presentation focuses on the role of social and management sciences researchers in enacting knowledge for social action, in the specific field of trade unionism. It draws on our experience, as researchers from two different research centres of the University of Liège2, in conducting a short-term intervention research ordered by a Belgian trade union. Our objective was to provide trade union delegates with educational and methodological support for launching a strategic reflexion on the union’s positioning regarding the challenges brought about by the digitalisation of work. We describe both the methodological framework implemented by the researchers (a questionnaire survey and focus groups) and the educational device settled by the union, which was aimed at enhancing the trade union delegates’ experience of digitalisation. This process that stimulates knowledge production and circulation is analysed on the basis of the phenomenology of knowledge defined by Freeman and Sturdy (2014). We first discuss the nature of our relationship with trade union executives who ordered the research. We particularly emphasise the role of three factors, namely trust (taming between two organizational cultures), time (strong pressure due to the preparation of the congress) and contingency (due to the lack of decision-making power of the steering committee), in (re- )framing the research project and thereby influencing knowledge production. Then, we describe the role performed by researchers as a role of methodological sifting that consists in imposing different frames on the trade union delegates’ experience of digitalisation. Ranging from « meeting frame » to questionnaires, the researchers’ sifts give different forms (inform) to delegates’ knowledge – which was inscribed in documents meant at circulating the union’s official position on digitalisation; enacted through different events as focus groups and conferences; and embodied by the union delegates who took part in the process.

Urban flood risk is influenced by many factors such as hydro-meteorological drivers, existing drainage systems as well as vulnerability of population and assets. The urban fabric itself has also a complex influence on inundation flows. In this research, we performed a systematic analysis on how various characteristics of urban patterns control inundation flow within the urban area and upstream of it. An urban generator tool was used to generate over 2,250 synthetic urban networks of 1 km². This tool is based on the procedural modelling presented by Parish and Müller (2001) which was adapted to generate a broader variety of urban networks. Nine input parameters were used to control the urban geometry. Three of them define the average length, orientation and curvature of the streets. Two orthogonal major roads, for which the width constitutes the fourth input parameter, work as constraints to generate the urban network. The width of secondary streets is given by the fifth input parameter. Each parcel generated by the street network based on a parcel mean area parameter can be either a park or a building parcel depending on the park ratio parameter. Three setback parameters constraint the exact location of the building whithin a building parcel. For each of synthetic urban network, detailed two-dimensional inundation maps were computed with a hydraulic model. The computational efficiency was enhanced by means of a porosity model. This enables the use of a coarser computational grid , while preserving information on the detailed geometry of the urban network (Sanders et al. 2008). These porosity parameters reflect not only the void fraction, which influences the storage capacity of the urban area, but also the influence of buildings on flow conveyance (dynamic effects). A sensitivity analysis was performed based on the inundation maps to highlight the respective impact of each input parameter characteristizing the urban networks. The findings of the study pinpoint which properties of urban networks have a major influence on urban inundation flow, enabling better informed flood-proof urban design. [less ▲]

Shallow reservoirs are often used in hydraulic engineering as sediment traps or storage basins, Sedimentation within these reservoirs depends on the flow pattern, which in turn depends on the shape of the reservoir. For short rectangular reservoirs, the main jet flows straight from the inlet to the outlet with on both sides identical recirculation zones. In longer reservoirs, however, the main jet reattaches to the side of the reservoir leading to a small and a large recirculation zone. Previous studies have found an empirical geometric relation describing the switch between these two different flow patterns. In this study, we demonstrate that this switch in flow pattern coincides with a maximization of energy dissipation in the shear layer between the main jet and the recirculation zones. To show this we described the power received from the jet by the recirculation zone as the product of a fluid-fluid friction coefficient and the square of the velocity difference times the shear velocity of the recirculation zone. This power is balanced by the bottom friction of the recirculation zone. Energy dissipation in the shear layer is then determined as the difference between the power performed by the jet and the power received by the recirculation zone. In this setup, energy dissipation is maximized by optimizing the friction coefficient. We show that for short reservoir lengths, energy dissipation is higher in the case of a symmetric flow pattern, while for longer reservoir the energy dissipation is higher for asymmetric flow patterns. The simulated switch between the two flow patterns appears to be very close to the empirical relation. This suggests that the flow pattem adapts in order to maximize energy dissipation between the jet and recirculation zones. The strength of this approach lies in the fact that no detailed knowledge of small scale processes is needed, while large scale structure formation can still be predicted. [less ▲]

Uncertainties in sea-level rise projections are mostly due to uncertainties in Antarctic ice-sheet predictions (IPCC AR5 report, 2013), because key parameters related to the current state of the Antarctic ice sheet (e.g. sub-ice- shelf melting) and future climate forcing are poorly constrained. Here, we propose to improve the predictions of Antarctic ice-sheet behaviour using new uncertainty quantification methods. As opposed to ensemble modelling (Bindschadler et al., 2013) which provides a rather limited view on input and output dispersion, new stochastic methods (Le Maître and Knio, 2010) can provide deeper insight into the impact of uncertainties on complex system behaviour. Such stochastic methods usually begin with deducing a probabilistic description of input parameter uncertainties from the available data. Then, the impact of these input parameter uncertainties on output quantities is assessed by estimating the probability distribution of the outputs by means of uncertainty propagation methods such as Monte Carlo methods or stochastic expansion methods. The use of such uncertainty propagation methods in glaciology may be computationally costly because of the high computational complexity of ice-sheet models. This challenge emphasises the importance of developing reliable and computationally efficient ice-sheet models such as the f.ETISh ice-sheet model (Pattyn, 2015), a new fast thermomechanical coupled ice sheet/ice shelf model capable of handling complex and critical processes such as the marine ice-sheet instability mechanism. Here, we apply these methods to investigate the role of uncertainties in sub-ice-shelf melting, calving rates and climate projections in assessing Antarctic contribution to sea-level rise for the next centuries using the f.ETISh model. We detail the methods and show results that provide nominal values and uncertainty bounds for future sea- level rise as a reflection of the impact of the input parameter uncertainties under consideration, as well as a ranking of the input parameter uncertainties in the order of the significance of their contribution to uncertainty in future sea-level rise. In addition, we discuss how limitations posed by the available information (poorly constrained data) pose challenges that motivate our current research. [less ▲]

A challenging aspect for experimental modelling of fluvial dike breaching is the continuous monitoring of the transient breach geometry. In dam breaching cases induced by flow overtopping over the whole breach crest (plane erosion), a side view through a glass wall is sufficient to monitor the breach formation. This approach can be ex- tended for 3D dam breach tests (spatial erosion) ifthe glass wall is located along the breach centreline. In contrast using a side view does not apply for monitoring fluvial dike breaching, because the breach is not symmetric in this case. We present a non-intrusive, high resolution technique to record the breach development in experimental models of fluvial dikes by means of a laser profilometry (Rifai et al. 2016). Most methods used for monitoring dam and dike breaching involve the projection of a pattern (fringes, grid) on the dam or dike body and the analysis of its deformation on images recorded during the breaching (e.g., Pickett et al. 201 1, Frank and Hager 2014). A major limitation of these methods stems from reflection on the water surface, particularly in the vicinity of the breach where the free surface is irregular and rippled. This issue was addressed by Spinewine et al. (2004), who used a single laser sheet so that reflections on the water surface were strongly limited and did not hamper the accurate processing of each image. We have developed a similar laser profilometry technique tailored for laboratory experiments on fluvial dike breaching. The setup is simple and relatively low cost. It consists of a digital video camera (resolution of 1920 >< 1080 pixels at 60 frames per second) and a swiping red diode 30 mW laser that enables the projection of a laser sheet over the dike body. The 2D image coordinates of each defomied laser profile incident on the dike are transformed into 3D object coordinates using the Direct Linear Transformation (DLT) algorithm. All 3D object coordinates computed over a swiping cycle of the laser are merged to generate a cloud of points. The DLT-based image processing method uses control points and reference axes, so that no prior knowledge is needed on the position, orientation and intrinsic characteristics of the camera, nor on the laser position. Refraction of the light and laser rays across the water surface needs to be taken into account, because the dike is partially submerged during the experiments. An ad hoc correction is therefore applied using the Snell-Descartes law. For dtis purpose, planar approximations are used to describe the shape of the water surface. In the presen- tation, we will discuss the resulting uncertainty and will detail the validation of the developed method based on configurations of known geometry with various complexity. The presented laser profilometry technique allows for a rapid non-intrusive measurement of the dike geometry evolution. It is readily available for laboratory experiments and has proven its performance (Rifai et al. 2017). Further adjustments are needed for its application to cohesive dike material due to the reduced visibility resulting from the higher turbidity of water. [less ▲]

Introduction: Patients in a minimally conscious state (MCS) have been subcategorized in MCS plus and MCS minus, respectively with and without command following capacity. Here we aim to characterize differences in MCS plus as compared to MCS minus by means of functional connectivity (FC). Method: Resting state functional magnetic resonance imagery (fMRI) was acquired in 292 MCS patients and a seed-based analysis was conducted on a convenience sample of 19 MCS patients (10 MCS plus and 9 MCS minus) and 35 healthy controls. We investigated the left and right frontoparietal networks (FPN), the auditory network and the default mode network (DMN). We employed a ROI-to-ROI analysis to investigate the inter-hemispheric connectivity and we investigated inter-group differences in grey and white matter volume by means of voxel-based morphometry. Results: We found a higher FC in MCS plus as compared to MCS minus in the left FPN, specifically between the left dorso-lateral prefrontal cortex and the left temporo-occipital fusiform cortex (TOFC). The FC of auditory network, right FPN and DMN, inter-hemispheric connectivity and structure of grey and white matter did not show differences between patients groups. Discussion: Our results suggest that the clinical sub-categorization of MCS is sustained by FC differences in a language-related executive control network. MCS plus and MCS minus patients are not differentiated by networks involved in auditory processing, perception of surroundings and internal thoughts, nor by differences in inter-hemispheric connectivity and in morphology.

Projectile points have recently taken a prominent position in debates on the complexity of Paleolithic human behavior. While the appearance of hunting weapons in the archaeological record was a central element in early discussions, the debate has shifted towards the appearance of specific projecting modes. Given that the organic propulsion tools (bow, spear-thrower) are only rarely preserved, energy has been invested in experiments to explore how the projecting mode can be identified based on the analysis of stone points. These experiments usually attempt to control selected parameters in projectile use (e.g., speed, target, angle of impact), but the ballistic parameters that are used are generally based on heterogeneous and not commonly reported studies. Little research has focused on the measurement of the complete ballistic performance of prehistoric weapons. We present the first results of a systematic ballistic study that quantifies and compares different modes of propulsion. [less ▲]

Polyolefins are an inexpensive class of compounds that can be used to prepare a plethora of different materials. Poly(ethylene) is the worldwide most produced polymer and is mostly synthesised by free radical polymerisation or catalytic coordination insertion using high temperature and pressure. The controlled radical polymerisation of ethylene is very difficult to achieve because of secondary reactions of this unconjugated monomer, e.g. chain transfer and termination reactions. Cobalt-mediated radical polymerisation (CMRP) represents a solution to control its polymerisation in mild conditions: in a reversible deactivation mechanism, a cobalt complex reversibly traps the active growing chains and converts them into dormant species, avoiding side reactions and allowing for a controlled polymerisation. Using CMRP, statistical copolymers of ethylene and vinyl acetate (VAc) have been synthesised, as well as block-like and block copolymers. Furthermore, functionalisation of the α- and ω-chain ends are now possible. Polymerising a vinyl bio-based monomer using CMRP has also been investigated, with the goal of forming ethylene copolymers. The copolymerisation behaviour of this novel monomer was investigated using vinyl acetate as a model and the structure and thermal properties were analysed. The monomer is very promising and copolymerisations with ethylene are undergoing. It is expected, that these completely new and highly interesting materials may act as compatibilisers for the dispersion of natural polymers, such as cellulose, into various polymer matrices.

La dégradation considérable de la qualité de l’eau et les utilisations concurentielles de cette ressource par tous les secteurs s’accèlèrent, notamment en région méditerranéenne. Certains pays souffrant déjà de la rareté de leurs ressources en eau seront de plus en plus menacés dans un futur proche. Cette situation de pénurie serait aggravée par les dérèglements climatiques qui menacent les ressources en eau par l’augmentation de l’évaporation des reservoirs et des plans d’eau et par la fréquence des inondatons et des sécheresses. La Tunisie fait partie des pays les plus vulnérables de la région méditerranéenne. Le pays est classé selon l’indice de Falkenmark parmi les pays en pénurie d’eau, ce qui rend la disponibilité naturelle de cette ressource insuffisante pour satisfaire une demande en hausse. En effet, selon l’organisation des nations unies pour l’alimentation et l’agriculture (FAO, 2014), les disponibilités en eau douce de la Tunisie baisseraient à 450 m3/habitant/an en 2030 et à 427 m3/habitant/an en 2050. En 2015, les apports cumulés aux barrages ont enregistré une baisse de 66% par rapport à la moyenne. Cette baisse a le plus affecté la région du Nord, forte contributrice au stockage d’eau de surface (plus de 80% des ressources en eau de surface). Le barrage Joumine était parmi les barrages les plus affectés par cette baisse enregistrant une perte de stockage de 37 Mm3 en une année, soit 30% de sa capacité utile actuelle. A cette baisse de la ressource s’associe la vulnérabilité à la pollution diffuse. En effet, le bassin versant de l’oued Joumine est un bassin versant agricole dominé par les cultures céréalières très exigeantes en intrants (192 milles tonnes d’Ammonitrate, 25,9 milles tonnes de superphosphate 45 et 82 milles tonnes de DAP pour le total des surfaces céréalières emblavées du pays) (DGPA, 2016). Dans ce travail, on estime ces apports issus des terres agricoles et évalue sa réponse face aux nombreuses pressions dans un contexte de changement climatique. La méthodologie adoptée implique, en plus des observations et prospection terrain, la représentation mathématique de la relation « pression – impact », modélisée par le logiciel PEGOPERA, outil de simulation numérique de l’écosystème rivière développé par l’Unité R&D de l’Aquapôle de l’Université de Liège. Le but étant de fournir une image de la qualité de l’eau de l’oued Joumine dans des conditions hydrologiques particulières, à un pas de temps journalier et en tout point du réseau en assurant des simulations physiquement basées avec un outil dédié au calcul déterministe des écosystèmes rivières à partir des données des débits mesurés, la température de l’eau, les insolations solaires et les rejets (Deliège et al., 2009; Deliege et al 2014 ; Grard et al 2014). La mise en place du modèle a nécessité la construction d’une base de données géographique à partir des informations relatives à l’occupation des terres et le relief, le tracé digitalisé des rivières et le découpage administratif par délégation. Des algorithmes de pré-processing PEGASE ont été appliqués pour la construction et la vérification de la topologie du réseau hydrographique, la génération des profils altimétriques des rivières et de la connectivité. Une méthode d’interfaçage a été par ailleurs définie avec le modèle agro-hydrologique SWAT en vue du calcul déterministe et explicite des apports diffus des sols tout en s’assurant de la cohérence des échelles temporelle et spatiale entre les deux modèles et des processus modélisés. Le modéle a été paramétré pour simuler l’état du systéme depuis l’année hydrologique 2015/2016 et des scénarios prospectifs sont en cours d’étude pour simuler la réponse du système dans des situations particulières, notamment les projections climatiques futures.

La mort de Raphaël Sanzio survenue à Rome le 6 avril 1520 provoqua un électrochoc au sein du milieu culturel romain. Célébré de son vivant, cet artiste incontournable le fut tout autant dans la mort. En attestent particulièrement les témoignages de contemporains, qu’ils soient hommes de lettres ou ambassadeurs. Cette communication sera à la fois l’occasion de se pencher sur ces précieux témoignages mais également d’appréhender comment cette disparition brutale fut perçue à travers l’historiographie ancienne et moderne. Ensuite, on analysera les conséquences de cet événement sur les développements artistiques de la première moitié du XVIe siècle. En effet, durant le printemps 1520, Raphaël était sollicité de toute part. Mais l’artiste n’était pas seul, et était secondé par une myriade de collaborateurs. Une fois le maître mort, qu’advint-il des commandes en cours ? Et surtout, quel tournant prit alors la carrière de ses élèves ?
