[more ▼]Bacillus subtilis is a PGPR (Plant Growth Promoting Rhizobacterium) Gram positive bacterium and a model for studying the in vitro formation or disruption of biofilms. At the liquid/air interface of standing cultures, B. subtilis forms thick pellicles of limited lifetimes. Some D-amino acids have been reported among the factors playing a role in the disassembly of B. subtilis biofilms and ylmE or racX mutants (in which the racemases YlmE or RacX are absent) show a delay in pellicle disruption. The racX encoding gene is part of a bicistronic operon in which the second gene (pbpE) codes for a Penicillin-Binding Protein, the PBP4* whose function is not characterized in Bacillus. Our studies aim to produce, purify and characterize the role of the PBP4* and RacX, YlmE racemases in relation with the disassembly of biofilms. Biochemical and structural data have been obtained and the role of the three proteins has been partly solved. X-ray structures will permit us to create inhibitor molecules against Bacillus subtilis biofilm formation or disassembly.

C’est précisément à dégager les enjeux de ce chapitre de son livre De la postcolonie que vise mon intervention. J’avais été très impressionnée, lors de mes recherches doctorales sur le kimbanguisme, par les analyses relatives au christianisme figurant dans Afriques indociles. Ces thèses sont tout à la fois creusées et déplacées dans « Le fouet de Dieu ». L’avant-propos de la deuxième édition du livre suggère brièvement une mise en perspective stimulante de ces pages. Prenant acte de la nécessité de désormais « penser avec et contre Fanon », Mbembe y souligne qu’elles ouvrent sur une conception du rapport éthique à autrui, qui prend chez lui la forme d’une prescription inconditionnelle : « donner la mort à la mort ». Mon interrogation se resserre autour de la thématique de l’altérité. En rassemblant en gerbe les problématiques du désir, de la domination et de la liberté, elle met au jour l’articulation profonde du religieux et du politique.

[more ▼]Les collines cuprocobaltifères du Katanga sont des lieux privilégiés pour étudier la variation des traits fonctionnels le long de gradients de stress métallique. Nous avons étudié la variation de six traits à l’échelle des espèces et de la communauté le long d’un gradient de cuivre et cobalt. D’autres paramètres tels que la concentration en phosphore et l’humidité du sol covarient positivement avec la teneur en métal du sol. Les contributions relatives du remplacement d’espèces et de la variabilité intraspécifique à la variabilité totale des traits dans les communautés ont été déterminées. A l’échelle de la communauté, la hauteur et la surface foliaire diminuent alors que les valeurs des quatre autres traits augmentent le long du gradient. Les espèces montrent des réponses variées, généralement non significatives. Pour tous les traits, le remplacement d’espèce est le moteur principal de la variation au sein des communautés. La concentration en métal du sol implique des réponses variées sur les différents traits et les différentes espèces. Nous montrons que la concentration croissante en métal privilégie le remplacement d’espèce par rapport à la variation intraspécifique et que les espèces répondent par différentes stratégies de tolérance à la concentration en métal du le sol. La variation des traits à l’échelle des communautés est essentiellement le reflet d’un changement dans les abondances des différentes formes de vie. Les espèces à xylopodes sont dominantes sur sol pauvre en métal alors que les annuelles sont dominantes sur sol très enrichi.

[more ▼]This work reports on the influence of -lactoglobulin (β-LGB) and of its denaturation on the adherence of quartz particles, taken as a model of particulate soil, on stainless steel AISI 304 with mirror finish. The substrate was soiled with quartz suspensions in water or in β-LGB solutions as such or previously heated at 75°C, and dried at room temperature or in an oven at 75°C. Cleanability was evaluated after exposure to water in a radial flow chamber. Auxiliary characterizations were the surface tension and protein concentration of the solution, surface analysis of the substrate by X-ray photoelectron spectroscopy (XPS) and contact angle measurements. The contact of stainless steel with -LGB led to adsorption of the protein, which dominated the composition of the organic layer with respect to contaminants initially present, and was not markedly desorbed upon rinsing. The presence of β-LGB at the quartz particle/substrate interface slightly increased the adherence, which was further increased when the protein was denatured. On the other hand, denaturation of -LGB enhanced its surfactant effect at the water/air interface. Comparison with systems investigated before suggests that the influence of protein via droplet spreading and soiling particles aggregation may be of minor importance compared to direct effects on the substrate/quartz interface. Stainless steel does not behave as a hydrophilic substrate owing to its surface contamination with organic compounds. It appears suitable to examine the influence of the initial surface state of stainless steel on its behavior regarding soiling and cleaning.

[more ▼]Printed circuit boards (PCB) are particularly problematic to recycle because of the heterogeneous mix of organic materials, metals, and glass fiber. PCBs are found in almost every electroelectronic equipment and their recycling process involves a pre-treatment to separate the products which contain targeted metals. In this work, a physical processing involving sequential shredding and hammer milling were used to obtain a comminuted sample from scrap printers PCBs. The thus prepared sample was analyzed for particle size distribution and by optical microscopy as well was subjected to pyrolysis, leachabilty and chemical composition determination by XRF. The metals concentration was determined by ICP and AAS. The PCBs have been also analyzed by SEM-EDS (micro-analysis and X-ray mapping). The results show that the studied PCBs are lead free, multilayer with 4 copper layers, have 45% of metals and the copper is present in significantly higher concentration than the rest of the metals.

[more ▼]Background: Patients with hypermobility suffer from joints problems and chronic pain is the most frequently reported symptom. Objective: Eccentric muscle strengthening could be very important to protect hypermobile joints. Design: Case report. Patient: A girl (16 y.o.) affected by an Ehler-Danlos syndrome presented pain in the right elbow and the right wrist after a season of tennis. Interventions: Her training consisted of wrist prono-supination and flexion-extension muscle group reinforcement and proprioceptive training. To protect the wrist against excessive load, the eccentric strengthening exercises of prono-supinator and flexor-extensor muscles of elbow and wrist were undertaken gradually, at increasing speeds within a limited range of motion in flexion and extension, on an isokinetic device after an evaluation. She was also given an orthesis restricting the joint range of motion of the wrist. Main outcome measurements: The evaluation was made by isokinetic evaluation, visual analog scale and MOS-SF36 questionnaire before and after training. Results: The patient rapidly noted a decrease in pain and an increase in the stability of her right arm even when playing tennis. Isokinetic evaluation objectified a significant improvement in maximal torque in flexion-extension muscles of the right elbow. She was also given individualized home exercises. Conclusions: The goal of this eccentric training is to avoid hypermobility by using the muscles as a protective brake in the control of joint positioning. Muscles can be reinforced in eccentric mode with starting position at the maximum length of these muscles when unstreched. The exercises can be carried out safely on an isokinetic device, at slow speed and limited range of joint motion to avoid risk of luxation. Thus, in this case report, the eccentric exercises using an isokinetic device were effective to safely reinforce the muscles as a protective brake for joint hypermobility and prevent pain during practicing tennis.

[more ▼]Common self-heal (Prunella vulgaris) plants are traditionally sown along the border of crops to enhance the biodiversity. Besides enhancing the biodiversity, they can also be a source of interesting compounds which could be important for food, pharmaceutical and cosmetic industries. The seeds of Common Yarrow were investigated for proteins, fatty acid compositions and polyphenolic compounds. The protein content was analyzed according to Dumas method, the extraction of oil was done using a cold extraction technique employing 2:1 chloroform/methanol as solvent, the fatty acid composition was determined using the gas chromatography and the amount of polyphenolic compounds were estimated using the method as described in European Pharmacopoeia, 8th edition. Common self-heal seeds can be of great commercial importance.

[more ▼]Ecomorphology is the study of the relationships between functional design and the environment. One of its aims is to understand how the environmental factors can constraint the performance of an organism or act on its phenotype. Different studies have already showed in different cetaceans that the number and shape of vertebrae can reflect the stiffness of the body and consequently can impact their swimming mode. The aim of this preliminary study is to establish relationships between characteristics of the vertebral column of different cetaceans and their ecology. To this purpose, we have studied meristic and morphometric data on the vertebrae (centrum length, height and width, neural and haemal spine height and the transverse process length) of different species of mysticetes and odontocetes coming from the Aquarium-Museum of Liège and Royal Institute of Natural Sciences of Bruxelles. Preliminary results showed the distinction of three morphotypes: firstly, the active, cruising, fast swimmers with rigid body, secondly, the maneuverers, slow swimmers with flexible body and thirdly, the steady swimmers.

[more ▼]The scarcity of field observations in some parts of the world makes difficult a deep understanding of some ecosystems such as humid tropical forests in Central Africa. Therefore, modelling tools are interesting alternatives to study those regions even if the lack of data often prevents sharp calibration and validation of the model projections. Dynamic vegetation models (DVMs) are process-based models that simulate shifts in potential vegetation and its associated biogeochemical and hydrological cycles in response to climate. Initially run at the global scale, DVMs can be run at any spatial scale provided that climate and soil data are available. In the framework of the BIOSERF project (“Sustainability of tropical forest biodiversity and services under climate and human pressure”), we use and adapt the CARAIB dynamic vegetation model (Dury et al., iForest - Biogeosciences and Forestry, 4:82-99, 2011) to study the Congo basin vegetation dynamics. The field campaigns have notably allowed the refinement of the vegetation representation from plant functional types (PFTs) to individual species through the collection of parameters such as the specific leaf area or the leaf C:N ratio of common tropical tree species and the location of their present-day occurrences from literature and available database. Here, we test the model ability to reproduce the present spatial and temporal variations of carbon stocks (e.g. biomass, soil carbon) and fluxes (e.g. gross and net primary productivities (GPP and NPP), net ecosystem production (NEP)) as well as the observed distribution of the studied species over the Congo basin. In the lack of abundant and long-term measurements, we compare model results with time series of remote sensing products (e.g. vegetation leaf area index (LAI), GPP and NPP). Several sensitivity tests are presented: we assess consecutively the impacts of the level at which the vegetation is simulated (PFTs or species), the spatial resolution and the initial land cover (potential or human-induced). First, we show simulations over the whole Congo basin at a 0.5◦ spatial resolution. Then, we present high-resolution simulations (1 km) carried out over different areas of the Congo basin, notably the DRC part of the WWF Lake Tele – Lake Tumba Landscape. Studied in the BIOSERF project, this area is characterized by a forest-savannah mosaic but also by swamp and flooded forest. In addition, forward transient projections of the model driven with the outputs of about thirty global cli- mate models (GCMs) from the new Coupled Model Intercomparison Project Phase 5 (CMIP5) will permit to outline the likely response of carbon pools to changing climate over the Congo basin during the 21th century.

[more ▼]DINEOF (Data INterpolating Empirical Orthogonal Functions) is a powerful tool based on EOF decomposition developed at the University of Liege/GHER for the reconstruction of missing data in satellite datasets, as well as for the reduction of noise and detection of outliers. DINEOF is openly available as a series of Fortran routines to be compiled by the user, and as binaries (that can be run directly without any compilation) both for Windows and Linux platforms. In order to facilitate the use of DINEOF and increase the number of interested users, we developed a web-based interface for DINEOF with the necessary parameters available to run high-quality DINEOF analysis. This includes choosing variable within selected dataset, defining a domain, time range, filtering criteria based on available variables in the dataset (e.g. quality flag, satellite zenith angle …) and defining necessary DINEOF parameters. Results, including reconstructed data and calculated EOF modes will be disseminated in NetCDF format using OpenDAP and WMS server allowing easy visualisation and analysis. First, we will include several satellite datasets of sea surface temperature and chlorophyll concentration obtained from MyOcean data centre and already remapped to the regular grid (L3C). Later, based on user’s request, we plan to extend number of datasets available for reconstruction.

[more ▼]C/2012 F6 (Lemmon) is a long period comet discovered by the Mount Lemmon Survey on 2012 March 23 at 5 AU from the sun. C/2012 F6 (Lemmon) reached perihelion on March 23, 2013 at 0.73 AU from the sun. In December 2012 the comet was unexpectedly bright, allowing us to make an extensive monitoring during several months with both broadband and narrowband filters to follow the evolution of the comet chemical composition. The monitoring was made with TRAPPIST robotic telescope installed at La Silla observatory [1]. TRAPPIST is a 60-cm telescope dedicated to the study of exoplanets and small bodies in the solar system. The telescope is equipped with a 2Kx2K FLI Proline CCD camera very sensitive in the blue and the red. A set of narrowband cometary filters designed by the NASA for the Hale-Bopp Observing Campaign [2] is permanently mounted on the telescope along with classic Johnson-Cousins B, V, Rc, and Ic filters. We observed the comet from December 11, 2012 to March 4, 2013 (pre-perihelion) and from April 29, 2013 to June 11, 2013 (post-perihelion). At least 2 or 3 observing runs per week were programmed during this period. We collected 1358 images on 52 nights. In January and February the comet visibility allowed us to make several long runs and to detect the comet rotational variability. From the comet images in narrowband filters we studied the gaseous coma chemical composition and activity by deriving OH, NH, CN, C2 and C3 production rates using a classical Haser model [3]. The production and properties of the dust component were studied through the observation of C/2012 F6 (Lemmon) with narrowband continuum filters at 344.2 nm (UC), 444.9 nm (BC), 525.7 nm (GC) and 713.0 nm (RC). We used A(θ)fρ [4] parameter as a proxy for the dust production.

[more ▼]Background Heart-type fatty acid-binding protein (H-FABP) is a low molecular weight protein involved in the intracellular uptake and buffering of long chain fatty in the myocardium. Troponin T is a component of the contractile apparatus of the striated musculature. Both are early markers for acute coronary syndrome. Objective The aim of our study was to compare the results obtained with the H-FABP and the highly sensitive cardiac troponins (hsTnT) and to test their cardiospecificity in healthy runners. Design Prospective, cohort study. Setting Amateur marathon runners. Patients 23 runners (marathon) were enrolled. Interventions We drowned blood samples at three times: just before (T0), just after (T1), and three hours after the end of the race (T3). Main outcome measurements H-FABP and hs-TnT were performed according to the manufacturer's instructions. A linear regression was calculated to observe if there is any correlation between the two biomarkers. Values above the 95th percentile for H-FABP (2.5 ng/mL) and the 99th percentile for hsTnT (14 ng/L) were considered as positive. Results At T0, none of the subjects were positive for hsTnT but 35% were positive for H-FABP; at T1, 83% for hsTnT and 100% for H-FABP; at T3, 83% for hsTnT and 96% for H-FABP. At T0, the regression equation was H-FABP T0=3.9454–0.1001×hsTnT T0; at T1: H-FABP T1=51.838–1.7026×hsTnT T1; at T3: H-FABP T3=47.977–1.6193×hsTnT T3. No correlation was observed between the 2 biomarkers. Conclusion We observed a significant increase of H-FABP and hsTnT in runners. These markers are independent to each other. These values could biologically correspond to a heart ischemia. These biomarkers could be helpful for the screening of cardiac risk among runners.

[more ▼]Gait impairment is considered as an important feature of disability in multiple sclerosis but its evaluation in the clinical routine remains limited. In this paper, we assess, by means of supervised learning, the condition of patients with multiple sclerosis based on their gait descriptors obtained with a gait analysis system. As the morphological characteristics of individuals influence their gait while being in first approximation independent of the disease level, an original strategy of data normalization with respect to these characteristics is described and applied beforehand in order to obtain more reliable predictions. In addition, we explain how we address the problem of missing data which is a common issue in the field of clinical evaluation. Results show that, based on machine learning combined to the proposed data handling techniques, we can predict a score highly correlated with the condition of patients.

[more ▼]The scarcity of field observations in some parts of the world makes difficult a deep understanding of some ecosystems such as humid tropical forests in Central Africa. Therefore, modelling tools are interesting alternatives to study those regions even if the lack of data often prevents sharp calibration and validation of the model projections. Dynamic vegetation models (DVMs) are process-based models that simulate shifts in potential vegetation and its associated biogeochemical and hydrological cycles in response to climate. Initially run at the global scale, DVMs can be run at any spatial scale provided that climate and soil data are available. In the framework of the BIOSERF project (“Sustainability of tropical forest biodiversity and services under climate and human pressure”), we use and adapt the CARAIB dynamic vegetation model (Dury et al., iForest - Biogeosciences and Forestry, 4:82-99, 2011) to study the Congo basin vegetation dynamics. The field campaigns have notably allowed the refinement of the vegetation representation from plant functional types (PFTs) to individual species through the collection of parameters such as the specific leaf area or the leaf C:N ratio of common tropical tree species and the location of their present-day occurrences from literature and available database. Here, we test the model ability to reproduce the present spatial and temporal variations of carbon stocks (e.g. biomass, soil carbon) and fluxes (e.g. gross and net primary productivities (GPP and NPP), net ecosystem production (NEP)) as well as the observed distribution of the studied species over the Congo basin. In the lack of abundant and long-term measurements, we compare model results with time series of remote sensing products (e.g. vegetation leaf area index (LAI), GPP and NPP). Several sensitivity tests are presented: we assess consecutively the impacts of the level at which the vegetation is simulated (PFTs or species), the spatial resolution and the initial land cover (potential or human-induced). First, we show simulations over the whole Congo basin at a 0.5◦ spatial resolution. Then, we present high-resolution simulations (1 km) carried out over different areas of the Congo basin, notably the DRC part of the WWF Lake Tele – Lake Tumba Landscape. Studied in the BIOSERF project, this area is characterized by a forest-savannah mosaic but also by swamp and flooded forest. In addition, forward transient projections of the model driven with the outputs of about thirty global cli- mate models (GCMs) from the new Coupled Model Intercomparison Project Phase 5 (CMIP5) will permit to outline the likely response of carbon pools to changing climate over the Congo basin during the 21th century.

[more ▼]The present study focused on re-cancellation behaviors in unilateral neglect (i.e., the tendency to search repeatedly items located on the right side in visual search tasks), and used a neuropsychological approach to identify the cerebral correlates of this deficit. Fourteen patients suffering from left neglect and 14 elderly age-matched controls performed a cancellation task without visual feedback. Neglect patients cancelled fewer targets than controls, and re-cancelled an abnormally high number of targets. Lesion maps were used to compare the location of brain damage in neglect patients with the highest versus the lowest percentage of re-cancellations. Anatomical data revealed that the right insula is commonly damaged in 5 out of 6 patients with the highest re-cancellation percentage, but is spared in the subgroup of patients with the lowest re-cancellation percentage. These results suggest that damage to the right insula may contribute to pathological visual search in spatial neglect, possibly by reducing interaction between the ventral and dorsal attention network (the latter being more directly involved in spatial processes).

[more ▼]Posée à la littérature, la question du style a, de longue date, suscité engouements et suspicions. Le style littéraire est aujourd’hui considéré comme la trace écrite de l’individu et l’indice d’une distance à l’égard de la langue commune. Une telle conception participe pleinement d’une modernité littéraire ayant érigé la singularité et la nouveauté en valeurs esthétiques. En ce sens, elle est aussi le résultat d’une révision importante, à partir du milieu du XIXe siècle, de l’idéal d’un « style parfait », entendu comme un « bien écrire régi par des règles valables pour tous, respectueux de principes qui semblent défier le temps et les plumes » (Philippe 2013 : 2). Au cours de cette évolution épistémique, de norme, le style devient vecteur de création. La transition a été identifiée tantôt en termes d’« autonomisation » du champ littéraire (Bourdieu), tantôt sous l’angle du « passage d’une littérature-discours à une littérature-texte » (Vaillant) et d’un affranchissement de la rhétorique (Philippe). Dès 1753, Buffon soutient dans son Discours sur le style que « le style est l’homme même », le définissant comme la marque textuelle d’une intériorité auctoriale contrastant avec le caractère commun et extérieur des faits traités. Au cours du XIXe siècle, ces considérations sont passées sous la plume des auteurs eux-mêmes, comme l’attestent la préface d’Edmond de Goncourt à Chérie, qui revendique pour l’écrivain « une langue personnelle, une langue portant [sa] signature », et la conception de Marcel Proust, formulée dans une lettre à madame Straus de 1908, selon laquelle « la seule manière de défendre la langue, c’est de l’attaquer ». L’actualité de la recherche est animée par la question du style à travers de nouvelles perspectives qui proposent de l’étudier de manière extensive, qu’il s’agisse de l’orienter dans une perspective transdisciplinaire empruntant volontiers à l’anthropologie ou de lui conférer une dimension existentielle propre à rendre compte du vécu intime des formes et de leurs significations. Parmi ces approches qui réévaluent la part d’individualité, de créativité ou d’originalité que désigne la notion de style, la sociologie de la littérature n’est pas en reste. Pourtant, le style semble constituer pour elle un point aveugle ou un impensé, sur fond du reproche récurrent qui lui est adressé de négliger la « surface verbale » du texte littéraire (Barthes). C’est donc aux différentes possibilités d’étudier le « style littéraire » en sociologie de la littérature qu’est dédié le présent colloque. Si une place lui a été réservée par la rhétorique et si une discipline à part entière lui a été consacrée, le style semble encore résister à une approche sociologique. Les principaux points d’achoppement concernent l’intégration, dans l’analyse stylistique, des conditions matérielles de production et de réception d’une œuvre, ainsi que les corrélations à établir entre les ordres socio-économique et esthétique. De nombreuses questions restent ainsi posées : comment rendre compte des variations significatives qui engagent à la fois des conceptions artistiques et la structure du champ littéraire ? existe-t-il des définitions concurrentes du style, circulant à un même moment ? comment la sociologie littéraire peut-elle rendre compte des étapes d’une évolution qui va du respect de la norme du bien écrire à la multiplication des expressions individuelles ?

[more ▼]In this article, we propose a robust methodology to select the most appropriate error distribution candidate, in a classical multiplicative heteroscedastic model. In a first step, unlike to the traditional approach, we don't use any GARCH-type estimation of the conditional variance. Instead, we propose to use a recently developed nonparametric procedure (Mercurio and Spokoiny, 2004): the Local Adaptive Volatility Estimation (LAVE). The motivation for using this method is to avoid a possible model misspecification for the conditional variance. In a second step, we suggest a set of estimation and model selection procedures (Berk-Jones tests, kernel density-based selection, censored likelihood score, coverage probability) based on the so-obtained residuals. These methods enable to assess the global fit of a given distribution as well as to focus on its behavior in the tails. Finally, we illustrate our methodology on three time series (UBS stock returns, BOVESPA returns and EUR/USD exchange rates).

[more ▼]The research focuses on the case study of the Belgian fair-trade milk “Fairebel”, which was created by dairy farmers a few months after the 2009 European milk crisis. This innovation is overseen by the “Fair Milk” programme set up by the European Milk Board (EMB), a European organization of dairy farmers, which has established five fair-trade milk labels in European countries (Austria, the Netherlands, Belgium, Luxembourg, and France). At the Belgian level, the case study of the “Fairebel” project shows how the dairy system is institutionally, politically, and technically locked in. In such an irreversible system, the developers of “Fairebel” have had to use cunning and espouse some contradictions (even inconsistencies) in order to build their idea of fair-trade milk and to achieve its commercialization in the real world of commodities. Also, the “Fairebel” project is trying to increase the market power of dairy farmers and by-passes entirely the dairy industry in Belgium, which refused to support the project. For example, the developers of “Fairebel” stock up on the spot market and the Fairebel” milk cartons are produced and filled by the Luxembourg co-operative dairy Luxlait. On this level, the “Fairebel” project is more a “reorientation of trajectories” than a radical transition of the system: It uses internal resources of the main system to try to change some of its detrimental consequences, such as the prices paid to dairy farmers, without forcing through associated structural transitions. On the European level of the EMB, in which “Fairebel” participates, the transition of the system is radicalized by changing the character and the structure of the regime itself (e.g. CAP): reversal of the balance of power between dairy farmers and dairy processors, re-appropriation of the means of production by the farmers, and modification of the economic and trade rules of the dairy products (e.g., monitoring agency). Taken together, these two levels of this fair-milk innovation strengthen each other, so that the transition that “Fairebel” has inspired is more radical than it would seem when the Belgian level is considered alone.

[more ▼]Quasi-loss of nationality : “is this a loss I see before me?” Prof. Gerard-René de Groot (University Maastricht, Aruba and Hasselt) Prof. Patrick Wautelet (University Liège) This paper focuses on situations in which a person is said never to have had the nationality of a country, even though (s)he assumed (and in many cases the authorities of the country concerned shared that assumption) that (s)he possessed that nationality. Contrary to situations of loss of nationality, where something is taken away which existed, those situations involve a decision that a nationality was never acquired. This subtle distinction between loss and non-acquisition will in most cases be lost on the persons concerned who will experience the decision as a loss of nationality. The central question of this paper is, whether these situations of quasi-loss differ so much from loss cases, that they have to be treated differently. If and insofar as this would be the case, a next question is, whether a person should under certain circumstances be protected against quasi-loss of her or his nationality. In order to answer these questions, the paper will first attempt to map out situations of quasi-loss in EU member states. Typical cases will be described in which a person did never acquire the nationality of the country, although (s)he was considered as a national before certain facts happened. Drawing on this taxonomy, the paper will offer a first attempt at uncovering whether national, European and international law offer some protection, and if yes, to which extent, for situations of quasi-loss. This paper will conclude with outlining best practices which Member States should comply with in handling quasi-loss situations.

[more ▼]Background Cardiac troponins (cTn) are considered as the best biomarkers for detection of myocardial cell injury and NT-proBNP as the best for the cardiac insufficiency. Objective Our aim was to compare cTnT and NT-proBNP levels before and after the stress tests, in sportive subjects. Design Prospective, cohort study. Setting Amateur marathon runners and ultrarunners. Patients 28 subjects (26 men, 42.5±11 yrs) were enrolled. Interventions Subjects ran the Maasmarathon (42.195 kilometers) and 33 subjects (33 men, 45.7±9.3 yrs) ran the Ultratour of Liège (Belgium; 67 km). All subjects gave their informed consent. We took blood sample before (T0), just after (T1) and 3 hours after the race (T3). Main outcome measurements cTnT concentrations were measured by high sensitive methods (hsTnT, Roche Diagnostics) on heparin plasma. The NT-proBNP was also determined with the kit Roche on heparin plasma. All statistical analyses were performed using Medcalc version 8.1 for Windows. P-value <.01 was regarded as statistically significant. Results A significant difference between hsTnT concentrations at T0 and T1 (P<.001), and between T0 and T3 (P<.001) for NT-proBNP have been observed, but not between T1 and T3. This observation appeared only after a strenuous exercise. However, up to now this type of exercise is not reproducible easily in a laboratory. Moreover, nobody knows if these observations would have cardiac consequences at long terms. Conclusion Measurement of cardiac troponins by high sensitive methods allows detecting significant release of biomarkers from the heart during exercise. The value of NT-proBNP are also significant but less than TnThs. We think that the TnThs could be an interesting tool in the future to help sport medicine to detect risk of developing a cardiac problem in the future or a sudden death.

[more ▼]Background: Even if eccentric exercises appear favourable in primary prevention of tendons lesions and, especially, in secondary prevention after tendinopathy, the biomechanical changes to the tissue are not yet clear. Objective: We aimed to better define the biomechanical changes that affect healthy tendon after eccentric and concentric training. Design: Randomised controlled trial. Participants: Eighteen Sprague-Dawley rats of 2 months. Interventions: The six rats in the control group (U) were not subjected to physical exercise. The 12 remaining rats (6 in each group) ran on a treadmill set at a +15° incline for concentric training (C) or a -15° incline for eccentric training (E), at a speed of 17 m/min for 1 h, three times per week for 5 weeks. Main Outcome Measurements: The tricipital, patellar and Achilles tendons were subsequently removed to perform a traction test until rupture, and a histological analysis was performed. Results: There was a significant improvement in the rupture force of the patellar and tricipital tendons between the U and E groups. The tricipital tendons in the control group presented a significantly smaller cross-section than the E- and C-trained groups, but none between E and C groups. No significant difference was observed for the mechanical stress at rupture per surface unit between the three groups for all three tendons. However, a tendency towards improvement these values was observed between the trained and the U groups for the patellar tendon. Histological studies demonstrated the tendency of the development of a greater number of blood vessels and a larger quantity of collagen in the eccentric group. Conclusions: The mechanical properties of tendons in rats improve after specific training, especially following eccentric training. Our results partly explained how mechanical loading, especially in eccentric mode, could improve the tendon structure.

[more ▼]Background: Difficulties in everyday life activities are core features of persons diagnosed with schizophrenia. Moreover, patients seem to demonstrate particular difficulties during complex and multitasking activities, such as cooking a meal (Semkovska et al., 2004). Multitasking refers to activities where the person has to: carry out and alternate between different tasks that vary in terms of priority, difficulty and duration; define the tasks’ targets; and where the person is faced with unexpected problems during the realization of these tasks (Burgess, 2000). However, at present, patients’ multitasking capacities have not been adequately examined in the literature due to an absence of suitable assessment strategies. We thus recently developed a computerized real-life activity task designed to take into account the complex and multitasking nature of certain everyday life activities where participants are required to prepare a room for a meeting – the Computerized Meeting Preparation Task (CMPT) Methods: Twenty-one individuals diagnosed with schizophrenia and 20 matched healthy controls completed the CMPT. During the CMPT, participants found themselves in a virtual room that they had to prepare for a meeting while respecting a list of instructions (the placement of the guests, the needed objects, the desired drinks, etc.). Patients were also evaluated with an extensive cognitive battery (assessing executive functions, attention, processing speed and memory), measures of symptomatology and real world functioning. To examine the ecological validity of the CMPT, 14 others patients were recruited and were given the computerized version and a real version of the meeting preparation task. Results: Results demonstrated that performance on the CMPT significantly differentiated patients and healthy controls for the total time to complete task, planning efficiency, and the respect of the instructions. Moreover, these variables were significantly correlated with executive functioning (i.e. cognitive flexibility and planning), suggesting the major implication of these cognitive processes in multitasking activities. Performance on the CMPT also significantly predicted up to 50% of real world functioning. Finally, performances on the computerized version and the real version of the meeting preparation task were highly correlated, suggesting good ecological validity. Discussion: In this study, we created a novel task involving the multitasking nature of real world activities. The results demonstrated that this approach provides a good indication of the real world functioning in patients diagnosed with schizophrenia. Moreover, results suggest a particular implication of executive functioning in multitasking activities. These findings suggest the importance of evaluating multitasking capacities in patients diagnosed with schizophrenia in order to predict real world functioning.

[more ▼]It is widely acknowledged that scientific research and science, technology and innovation (STI) policies within the US and the EU have gone through deep changes for about 30 years. Many scholars from science and technology studies and innovation studies have investigated these policy changes, and the publication of “The New Production of Knowledge” (Gibbons et al., 1994) paved the way for vigorous debates on regimes of knowledge production (Hessels & Van Lente, 2008). While different general models were proposed to describe a transition (see, e.g. “mode 2 production of knowledge”, “post normal science”, “strategic science”, “academic capitalism”), these models often posit a dichotomous history, stating that a new regime simply succeeded the previous one (Rip, 2000). In a nutshell, the old regime characterized by strong public intervention and a linear conception of innovation is replaced by a new regime where research and innovation are conceived in systemic terms, regarding their strategic interest for the economy and their societal relevance. This dichotomous conception of STI policy change has been criticized regarding its historical accuracy, e.g. with Pestre (2003), showing that the autonomy of research that characterizes the old regime, or “mode 1” is While the diagnosis of these various science and technology policy studies is not to be dispraised concerning the different effects they emphasize, These macro-perspectives are of little use when it comes to study a local situation they lack acuteness to properly describe and compare empirical observation of such policy changes. This issue is even more salient for empirical work to be conducted in states where multi-level policies are crafted on different, sometimes overlapping national and regional polities. In Belgium, the case in point in my PhD researches, the above-mentioned studies are of little use to characterize the actual state and interplay of Walloon and Flemish STI systems. Hence, there is a need to develop theoretical approaches paying greater attention to local specificities and nuances. My proposal builds on an analysis of STI policies based on coexisting, and sometimes competing “narratives”. In the vein of Stone (1989) and Radaelli (2000), this paper aims at comparing the different policy narratives that circulates as rationale for STI policies in Wallonia, to identify their variants and to study their interplay. Policy narratives give meaning to complex realities, they help making sense of things, but they also contain a plot; they are articulating elements in a logical sequence (with, e.g., causalities, cf. Stone, 1989). As such, they are resources for action: they are descriptive and prescriptive. The broad literature of innovation studies, and its diffusion through the EU or the OECD already provides the Walloon STI stakeholders with different master-narratives (Sum & Jessop, 2013). So far, I could distinguish four different master-narratives in the literature as well as in Walloon stakeholders ‘discourses: • “The Knowledge-based economy” (KBE). KBE seems to be the “dominant” master-narrative today. In a nutshell, this narrative runs as follow (see OECD, 1996): knowledge is the source of economic growth. Since innovation and market success are better encountered through network management and the intertwinement of industry and university, STI institutions must be organized accordingly, in order to achieve a sustained growth and a “better competitiveness” o Variants of this narrative are, e.g. the triple-helix model (Etzkowitz & Leydesdorff, 2000), or National innovation system (Freeman, 1987, Lundvall, 1988). • Grand societal challenges: This recent master-narrative is being promoted by the OECD and the EU (see, e.g., Lund Declaration, 2009). It states that scientific research should benefit of high (public) funding in certain areas, or regarding certain issues. High means for strategic research should help to solve major problems such as climate change, ageing population, energy supply and consumption, cancer, etc. This narrative calls for mission oriented STI policy, so the concern here is not (solely/primarily) economic (Kallerud et al 2013). • “Science, the endless frontier” - continued: famously reported by V. Bush (1945), this master-narrative is still of common use among STI stakeholders. With this narrative, science is considered a public good, the state has to fund it because the linear conception of innovation and serendipity assure technological and economic progress in the end – the rationale is based on economic aspects (the state must fund research because it is a special kind of good and the market efficiency will not work, and basic research is the source of marketable innovation). • “Science for the sake of science”: in this narrative, science is considered as common good regardless of the potential economic impacts (and usefulness to address other societal issues) – we can make a parallel with the idea that artistic creation is worth it: for the beauty, for the critique, science here is considered as a superior activity that brings rationality and knowledge to the society as long as it is independent from “external influences” (Bonneuil & Joly, 2013) – cf. “mertonian Ethos” of Communalism, Universalism, Disinterestedness, Originality and Skepticism. Other examples / variants of this narrative include the idea that science contributes to the greatness of Nation, that science fights obscurantism, and so on and so forth. (examples : peer review, excellence, Copernican revolution are compatible storylines with science for the sake of science : a self-supporting system) While these master-narratives are present in international, academic literature, this paper focuses on their local manifestations. This study compares three critical moments: in different situations, various STI stakeholders (government, researchers, administrative staff, journalists, academic authorities, etc.) publicly expressed their views on the organization and funding of scientific research and innovation activities, and the role of STI within the region. I analyzed the discourses in press articles, policy documents, public statements, allocutions and opinion paper, blogs, etc. I intentionally sampled for heterogeneity since I’m looking for variations and multiple use of narratives. The analysis of the Walloon case permits to overcome the double dichotomy of dominant vs. counter narrative and old vs. new regime. The different narratives, in context, are concurrent but they are not mutually exclusive: while the narratives purport different ideologies, different visions of the role of science and of the state intervention, one is not being erased by the advent of another. Rather, I could find out that narratives “overlap”, and one narrative does not constitute the only resource of a (group of) actors. In situation, the actors use one or multiple narratives, regarding the context, the public, the goal of a policy, etc., in a dynamic of conflict or compromise. This description of the transition is more accurate than the one provided with a sequence of two regimes, since the flexible use of multiple narratives accounts for the continuity of certain institutions (justified by, e.g., a version of “science for the sake of science”) as well as for certain reforms in STI policy (that are inspired by the KBE narrative, for example).

For realistic ocean systems, only a relatively small number of ensemble members can be calculated. A localization of the ensemble increment is thus necessary to filter out spurious long-range correlations. However, the conservation of the global property will be lost if the assimilation is performed locally since the conservation requires a coupling between model grid points, which is filtered out by the localization. In the ocean, the distribution of observations is highly inhomogeneous. Systematic errors of the observed parts of the ocean state can lead to spurious systematic adjustments of the non-observed part of the ocean state due to data assimilation. As a result, global properties which should be conserved, increase or decrease in long-term simulations. We propose an assimilation scheme (with stochastic or deterministic analysis steps) which is formulated globally (i.e. for the whole state vector) but where spurious long-range correlations can be filtered out. The scheme can thus be used to enforce global conservation properties and non-local observation operators. Both aspects are indeed linked since one can introduce the global conservation as a weak constraint by using a global observation operator. The conserved property becomes thus an observed value. The proposed scheme is tested with the Kuramoto-Sivashinsky model which is conservative. The benefit compared to the traditional covariance localization scheme (with an ad-hoc step enforcing conservation) where observations are assimilated sequentially is shown. The assimilation scheme is suitable to be implemented on parallel computers where the number of available computing cores is a multiple of the ensemble size.

[more ▼]In België bestaat er een nauwe band tussen talen (Nederlands-Frans) en regionale identiteiten (Vlaming-Waal). Echter, de aanwezigheid van Franstaligen in Vlaanderen en van Nederlandstaligen in Wallonië laat zien dat deze band niet automatisch is. Deze twee (onder)bevolkingsgroepen lijken dus een ideaal studiemateriaal om de ingewikkelde relatie tussen taal (talen) en identiteit(en) te bestuderen. Ondanks de belangstelling van verschillende disciplines (onder meer politieke wetenschappen, geschiedenis, sociologie en taalkunde) voor dit onderwerp, valt het toch op dat deze bevolkingsgroepen nog nooit onderzocht werden. In dit onderzoeksproject willen we daarom aan de hand van biografische gesprekken nagaan (i) hoe deze minoriteitsgroepen in een anderstalige context hun identiteit opbouwen, en (ii) in hoeverre ze identiteitsstrategieën gebruiken naargelang van de communicatiecontext waarin ze zich bevinden. Om deze vragen te beantwoorden, zullen biografische gesprekken verzameld worden die die vanuit het interdisciplinaire perspectief van de sociologie, de sociale psychologie, de sociolinguïstiek en de taalkunde geanalyseerd zullen worden. In deze bijdrage zullen we specifieker ingaan op de methodologie die wij zullen gebruiken om deze biografische gesprekken te analyseren. We zullen meer bepaald uitgaan van een tweeledige analyse van identiteitsmarkeerders. Ten eerste zullen we een semantische studie van de identiteitscategorieën verrichten, door de lexicale eenheden te bestuderen die door de informanten gebruikt worden om hun identiteit te omschrijven. Het is hiermee de bedoeling om de sociale categorieën die de respondenten gebruiken verder in kaart te brengen. Ten tweede zullen wij een psychosociale studie van de identiteitsstrategieën van de informanten verrichten. Vanuit dit perspectief kan een identiteit beschouwd worden als het resultaat van de interactie tussen een “identiteit voor zichzelf” en een “identiteit voor de anderen”. In dit onderdeel van onze studie willen we de persoonlijke identiteitsstrategieën van de informanten aan het licht brengen onder meer door hun identiteitskeuzes, zoals bijvoorbeeld de keuze voor een taalvariëteit in een bepaalde communicatiecontext, nauwkeurig te bestuderen. Deze tweedelige methode zal het mogelijk maken om de relatie tussen taal en identiteit in België beter te begrijpen en nauwkeuriger te kunnen omschrijven.

[more ▼]The thymus may be compared to a computer highly specialized in the programming of central immunological self-tolerance. A unique thymus first appeared some 500 million years ago in cartilaginous fishes, at the same time or shortly after the emergence of the adaptive immune system. A new paradigm of neuroendocrine self-peptides has been proposed, together with the definition of neuroendocrine self. Neuroendocrine self-peptides are secreted by thymic epithelial cells (TECs) not according to the classic model of neurosecretion, but are processed for presentation by the thymic major histocompatibility complex (MHC) machinery. The autoimmune regulator (AIRE) gene/protein controls the transcription of neuroendocrine genes in TECs. Presentation of neuroendocrine self-peptides in the thymus is responsible for the clonal deletion of self-reactive T cells directed toward neuroendocrine antigens, which emerge during the random recombination of gene segments encoding variable parts of the T cell receptor for the antigen (TCR). Quite paradoxically, neuroendocrine self-peptide presentation in the thymus also generates regulatory T (tTreg) cells that inhibit, in the periphery, those self-reactive T cells having escaped thymic negative selection. Several arguments indicate that the origin of autoimmunity directed against neuroendocrine glands results from a primary defect in the intrathymic programming of self-tolerance to neuroendocrine principles. This defect may be genetic or acquired, for example during a viral infection. This novel knowledge of normal and pathologic functions of the thymus constitutes a solid scientific basis for the development of a novel type negative self-vaccination against type 1 diabetes.

[more ▼]That a modern Dutch poet should have found inspiration in Classical Chinese poetry and philosophy may seem rather unlikely. Yet, the contents of his personal library and a number of statements made in interviews reveal how Hans Faverey (1933-1990) had a great interest in oriental literature, art and thought (especially Taoism and Buddhism). Although many articles have been devoted to the use and function of intertext in Faverey’s poetry, scant attention has been paid to the possible influence of Chinese philosophers and poets on his work. I will argue that Faverey’s obsession with themes like emptiness, stillness and silence may be interpreted as an attempt to integrate some fundamental Taoist and Buddhist ideas into his writing. Taking Faverey’s oriental library as my starting point, and contextualizing it with reference to Tang dynasty poets such as Wang Wei and Li Shang-Yin, and quotations from Kung Sun Lung and the School of Names, I aim to shed a clearer light on those possible connections. The first part of my paper will focus on a number of general concepts from Chinese literature and philosophy, and discuss how Faverey assimilated these concepts into his own poems. The second part of my presentation will be devoted to a comparison between the Tao as text and a selection of Faverey’s work in order to highlight possible parallels in their use of symbols and imagery. Since Faverey, as a poet, was constantly working with and thinking about the written word, he may have been struck not only by Chinese philosophy itself but also by the way in which these thoughts had found their expression in language. The structure of the Chinese language and its penchant for paradoxical turns of phrase may have held an additional appeal for the Amsterdam poet, renowned for his pithy, hermetic writing style that abounds in paradoxes and uncommon allusions.

[more ▼]In comparison with the wood charcoals uncovered in the soils of the temperate regions, charcoals from the tropical regions remain little studied yet, in particular those from the dense humid forests of Central Africa. Here we aim at showing the interest of the analysis of soil charcoals so as to understand the current environments through some examples of taxonomical identifications conducted on charcoals sampled in several soil pits in Cameroon and in the Republic of the Congo. These charcoals were hand-split then observed under an incident light microscope. The anatomical features that are hold in the charcoals and described according to a standard method were compared to wood samples from the reference collection of the RMCA. Results demonstrated that the identified species are still present in the vegetal environment today and that only limited changes occurred over the past two millennia. Charcoal analysis can thus allow a better understanding of the past history of the forests in relationship with the ancient disturbances. The temporal and spatial framework of human settlements as well as the impact of the colonial period on the evolution of the forest is also discussed.

[more ▼]In the seventeenth century, the Roman proclamations of beatification or canonization generated a large number of festivities and spectacular events in many parts of the Monarchy of Spain. Yet, in the Netherlands, they received a fainter echo and left a limited number of sufficiently documented testimonies. Two cases, however, are exceptions: the canonization of Ignatius of Loyola and Francis Xavier triumphantly celebrated by the Belgian Jesuits in 1622, and the beatification of Francisco Borgia in 1624, i.e., the elevation to the Catholic pantheon of three Spanish saints rejoiced by an order marked by its hispanophile nature, in provinces recently returned to the Spanish Crown. I will seek to define the Hispanic features of these events and I will particularly stress the very noticeable way how the Spanish communities, present in the Low Countries, committed themselves in these festivities.

[more ▼]Our doctoral research is conducted at the University of Liege, under the supervision of Professor Philippe Raxhon (Contemporary History). This work falls within the interuniversity and interdisciplinary project “commemorating WWI” launched by the Fédération Wallonie-Bruxelles (French Community), the Steering Group of which is led by Professor Laurence Van Ypersele (Université Catholique de Louvain). The research focuses on the following topic: Experiences and remembrance of Belgian jurists on issues of international law during the First World War (1914-1918). Belgium, that had been neutral since its independence in 1831, soon became an active reflection centre and a land of innovation for international law, as shown by the foundation of the Institute of International Law (IDI) in Ghent in 1873. Belgium’s neutrality was violated in August 1914 and its territory, the only one, was occupied at 90% by the Germans, putting the country in a unique position that encouraged its International Law experts to revise their practices in view of their experiences and their remembrance of war. As a matter of fact, between 1918 and 1940, they held a prominent position on a global scale (LN, etc.). How the field of these law experts, its practices, its networks (European/American) and its international influence (1873-1940) evolved as a result of WWI lies at the heart of our thesis.

The wavelet leaders method enables us to exhibit the monofractal nature of these signals. Then, we define a climate classification relying on the Zygmund-Hölder spaces and show that it matches the Köppen classification. By doing so, we evidence the existing relation between the regularity of the temperature data (obtained through functional spaces) and the type of climate.

[more ▼]Multifractal analysis is concerned with the study of very irregular signals. For such functions, the pointwise regularity may change widely from a point to another. Therefore, it is more interesting to determine the spectrum of singularities of the signal, which is the Hausdorff dimension of the set of points which have the same Hölder exponent. The spectrum of singularities of many mathematical functions can be determined directly from its definition. However, for many real-life signals, the numerical determination of their Hölder regularity is not feasible. Therefore, one cannot expect to have a direct access to their spectrum of singularities and one has to find an indirect way to compute it. A multifractal formalism is a formula which is expected to yield the spectrum of singularities from quantities which are numerically computable. Several multifractal formalisms based on the wavelet coefficients of a signal have been proposed to estimate its spectrum. The most widespread of these formulas is the so-called thermodynamic multifractal formalism, based on the Frish-Parisi conjecture. This formalism presents two drawbacks: it can hold only for spectra that are concave and it can yield only the increasing part of the spectrum. This first problem can be avoided using Snu spaces. The second one can be avoided using a formalism based on wavelet leaders of the signal. In this talk, we propose a new multifractal formalism, based on a generalization of the Snu spaces using wavelet leaders. It allows to detect non concave and non increasing spectra. An implementation of this method is presented in the talk "A new multifractal formalism based on wavelet leaders: detection of non concave and non increasing spectra (Part II)" of T. Kleyntssens.

[more ▼]For several years, mesenchymal stem cells (MSC) have been evaluated in vivo and in vitro for their immunomodulatory, anti-inflammatory, anti- ischemia-reperfusion injury and “tissue repair” properties. These characteristics could make them interesting in various clinical applications, and particularly in organ transplantation. Taking advantage of our centre expertise and experience concerning MSC use in graft-versus-host disease after bone marrow transplantation and using already functioning GMP-compliant laboratory able to produce clinical-grade MSC, we initiated in 2011 a first trial exploring safety and tolerability of third party MSC infusions after kidney or liver transplantation in a prospective phase I-II study. In this study, after successful transplantation, 10 liver and 10 kidney transplant recipients under standard immunosuppressive treatment (tacrolimus, mycophenolate, steroids) receive an intravenous infusion of 1.5 - 3x106/kg of third-party MSC, on post-operative day 3+/-2. These patients are prospectively compared to the same number of liver and kidney transplant recipients who meet inclusion criteria but do not receive MSC infusion. Safety is assessed by recording side effects, including opportunistic infections and cancers. Immunosuppressive potential is evaluated by rejection episode rates, graft/patient survivals, immunohistology of 3-month (kidney) and 6-month (liver) graft biopsies, and in vitro evaluation of recipient immunity profile. In a second step, reduction (kidney) and progressive weaning (liver) of immunosuppression is attempted in recipients who received MSC. Inclusion of liver patients is now complete, and to date 3 kidney patients received MSC. Primary results will be presented, and complete 6-month liver results are expected for the end of 2014. The next step will be to assert the immunosuppressive potential of MSC after organ transplantation, and the opportunity to develop larger randomised, controlled, phase III trials.
