The Extreme Ultraviolet Imager (EUI) on-board the Solar Orbiter mission will provide full-sun and high-resolution image sequences of the solar atmosphere at selected spectral emission lines in the extreme and vacuum ultraviolet. After the breadboarding and prototyping activities that focused on key technologies, the EUI project has completed the design phase and has started the final manufacturing of the instrument and its validation. The EUI instrument has successfully passed its Critical Design Review (CDR). The process validated the detailed design of the Optical Bench unit and of its sub-units (entrance baffles, doors, mirrors, camera, and filter wheel mechanisms), and of the Electronic Box unit. In the same timeframe, the Structural and Thermal Model (STM) test campaign of the two units have been achieved, and allowed to correlate the associated mathematical models. The lessons learned from STM and the detailed design served as input to release the manufacturing of the Qualification Model (QM) and of the Flight Model (FM). The QM will serve to qualify the instrument units and sub-units, in advance of the FM acceptance tests and final on-ground calibration. [less ▲]

The seasonal storage should allow reaching a nearly 100 % solar fraction for space heating of a "low energy" building". The selected adsorbent and adsorbate are respectively bromide strontium and water. The studied system, including the building and the ground exchanger, is simulated using the dynamic simulation software TRNSYS. Results show that expected performances are reached with a borehole of 100 m. The evaporation temperatures computed are really close to 0°C which might cause some problems. But an advanced research would maybe impose a deeper borehole to avoid cooling the ground on the long term. [less ▲]

Les nouvelles "Holunderblüte" (1863) de Wilhelm Raabe et "Ein Bekenntnis" (1887) de Theodor Storm allient psychologie, maladie et narration. Les deux textes racontent l’histoire de médecins qui à la fin de leur vie se questionnent sur leur propre responsabité dans un épisode du passé qui changea définitivement le cours de leur existence: la maladie et la mort de l’être qui leur était le plus cher (une jeune fille chez Raabe, l’épouse chez Storm). Par rapport aux études psychanalytiques très nombreuses dans la recherche sur Storm, cette étude souhaite montrer que la profondeur psychologique des textes doit être décrite par une analyse tenant compte du rôle anthropologique de la narration. Au niveau des narrateurs, la narration a ainsi une valeur curative pour ces deux médecins souffrant de sentiments de culpabilité et souhaitant retracer leur vie comme un sentier linéaire, cohérent et imbibé de sens. Les fonctions anthropologiques de la narration (production de sens, réduction de la contingence et de l’angoisse) auxquelles font appel ces individus sont toutefois relativisées par les textes eux-mêmes qui par leur forme et par le motif du labyrinthe évoquent l’aléatoire, la contingence et l’absence de sens.

Ce travail vise à interroger la manière dont les jeux vidéo et les dynamiques de détournement qu’ils suscitent chez les joueurs redéfinissent la traditionnelle opposition entre consommation et création. Dans ce but, nous étudierons un usage spécifique du médium vidéoludique qui s’est institué en véritable pratique créative sur internet : le speedrun (et son dérivé, le tool-assisted speedrun). L’analyse se déroulera en deux temps : une première partie envisagera les déplacements concrets qu’opère le speedrun dans les notions liées au pôle de la réception (qu’est-ce qu’être un joueur ou un spectateur au sein de ce domaine ?) ; la seconde étudiera la façon dont cette pratique participe à redéfinir le pôle de la production (que deviennent les notions d’auteur, d’œuvre et de création dans le cadre de cette activité ?).

the field data come from plot scale studies, the watershed scale seems to be more appropriate to understand them. Currently, small unmanned aircraft systems and images treatments are improving. In this way, 3D models are built from multiple covering shots. When techniques for large areas would be to expensive for a watershed level study or techniques for small areas would be too time consumer, the unmanned aerial system seems to be a promising solution to quantify the erosion and deposition patterns. The increasing technical improvements in this growth field allow us to obtain a really good quality of data and a very high spatial resolution with a high Z accuracy. In the center of Belgium, we equipped an agricultural watershed of 124 ha. For three years (2011-2013), we have been monitoring weather (including rainfall erosivity using a spectropluviograph), discharge at three different locations, sediment in runoff water, and watershed microtopography through unmanned airborne imagery (Gatewing X100). We also collected all available historical data to try to capture the “long-term” changes in watershed morphology during the last decades: old topography maps, soil historical descriptions, etc. An erosion model (LANDSOIL) is also used to assess the evolution of the relief. Short-term evolution of the surface are now observed through flights done at 200m height. The pictures are taken with a side overlap equal to 80%. To precisely georeference the DEM produced, ground control points are placed on the study site and surveyed using a Leica GPS1200 (accuracy of 1cm for x and y coordinates and 1.5cm for the z coordinate). Flights are done each year in December to have an as bare as possible ground surface. Specific treatments are developed to counteract vegetation effect because it is know as key sources of error in the DEM produced by small unmanned aircraft systems. The poster will present the older and more recent changes of relief in this intensely exploited watershed and notably show how unmanned airborne imagery might be of help in DEM dynamic modelling to support soil conservation research.

To extend its photocatalytic activity to visible light, TiO2 has been doped in situ through the cogelation sol-gel proces with two dyes : free metal tetra(4-carboxyphenyl)porphyrin and nickel tetra(4-carboxyphenyl)porphyrin. DR and FT-IR spectroscopies have been performed to determine the interaction between porphyrins and TiO2. Cristallinity and specific surface area have been measured by XRD and N2 adsorption. The photoactivity of the doped TiO2 xerogels has been evaluated for p-nitrophenol (a model water pollutant) degradation under visible light and a kinetic study has been performed. The samples allow the degradation of 40% of p-nitrophenol in 6 h which makes them very promising for water decontamination under natural light. A kinetic study of p-nitrophenol degradation with the Ni-doped catalyst has shown that the best kinetic model involves one type of active site corresponding to the hole h+ of electron-hole pairs created at the TiO2 surface by light. The rate determining step consists of the surface reaction between adsorbed p-nitrophenol and adsorbed OH• radicals. [less ▲]

We introduce a new formalism for computing expectations of functionals of arbitrary random vectors, by using generalised integration by parts formulae. In doing so we extend recent representation formulae for the score function introduced in \cite{nourdin2013entropy} and also provide a new proof of a central identity first discovered in \cite{guo2005mutual}. We derive a representation for the standardised Fisher information of sums of i.i.d. random vectors which {we} use to provide rates of convergence in information theoretic central limit theorems (both in Fisher information distance and in relative entropy) {and a Stein bound for Fisher information distance.} [less ▲]

Bisphenol A (BPA) is documented in several studies to be a well-known source of food contamination. Recently, the European Union took a series of measures, including a ban for the import and sale of polycarbonate (PC) baby bottles to reduce BPA exposure of infants. Plastic alternatives to PC, which have massively appeared on the Belgian market, include polypropylene (PP), silicone, polyamide (PA) and polyethersulfone (PES). In a recent opinion (No. 8697, 11.03.2010), the Belgian Superior Health Council issued its concern regarding the alternatives to PC currently used. Furthermore, they asked to investigate the possible risks associated with the use of these alternatives. In this study, a screening towards the endocrine activity of chemicals migrating from PC alternatives, identified by the group of Simoneau, was performed by using different reporter gene assays. Furthermore, the genotoxic potential of these compounds was also assessed with the Vitotox assay, an indicator test for DNA damage. The aim of the screening was to select the substances that may present a risk for human health and thus require further characterization. [less ▲]

Continuous Ventricular Stroke Work (VSW) estimation requires accurate estimate of both stroke volume and aortic pressure. However, accurate beat-to-beat stroke volume measurement is highly invasive and thus typically unavailable in clinical practice. This study analyses the accuracy of a model-based method estimating relative change in VSW using only aortic pressure measurements. Using data from porcine experiment, the correlation coefficient was determined between the relative change of VSW from directly measured data and the model-based estimate of VSW. The result showed good agreement with, R=0.71. The model accurately captured the trend of VSW using only aortic pressure measurements and thus offers significant clinical value in early diagnosis and improving care for cardiovascular dysfunction.

Understanding the formation of sdB stars is one of the remaining challenges of stellar evolution theory. Competing scenarios have been proposed to account for the existence of such evolved objects. They give quite different mass distributions for resulting sdB stars. Detailed asteroseismic analyses, including mass estimates, of 15 pulsating hot B subdwarfs have been published in the past decade. Masses have also been reliably determined by light curve modeling and spectroscopy for 7 sdB components of eclipsing or reflection binaries. We present here the empirical mass distribution of sdB stars on the basis of these samples. Implications are also briefly discussed. [less ▲]

Monolithic, large grain, (RE)Ba2Cu3O7 high-temperature superconductors (where RE denotes a rare-earth ion) are known to be able to trap fields in excess of several teslas and represent thus an extremely promising competing technology for permanent magnet in several applications, e.g. in motors and generators. In any rotating machine, however, the superconducting permanent magnet is subjected to variable (transient, or alternating) parasitic magnetic fields. These magnetic fields interact with the superconductor, which yields a reduction of the remnant magnetization. In the present work we quantify these effects by analysing selected experimental data on bulk melt-textured superconductors subjected to AC fields. Our results indicate that the non-uniformity of superconducting properties in rather large samples might lead to unusual features and need to be taken into account to analyse the experimental data. We also investigate the evolution of the DC remnant magnetization of the bulk sample when it is subjected to a large number of AC magnetic field cycles, and investigate the experimental errors that result from a misorientation of the sample or a mispositioning of the Hall probe. The time-dependence of the remnant magnetization over 100000 cycles of the AC field is shown to display distinct regimes which all differ strongly from the usual decay due to magnetic relaxation.

Complex non-linear and dynamic processes lie at the heart of the planet formation process. Through numerical simulation and basic observational constraints, the basics of planet formation are now coming into focus. High resolution imaging at a range of wavelengths will give us a glimpse into the past of our own solar system and enable a robust theoretical framework for predicting planetary system architectures around a range of stars surrounded by disks with a diversity of initial conditions. Only long-baseline interferometry can provide the needed angular resolution and wavelength coverage to reach these goals and from here we launch our planning efforts. The aim of the "Planet Formation Imager" (PFI) project is to develop the roadmap for the construction of a new near-/mid-infrared interferometric facility that will be optimized to unmask all the major stages of planet formation, from initial dust coagulation, gap formation, evolution of transition disks, mass accretion onto planetary embryos, and eventual disk dispersal. PFI will be able to detect the emission of the cooling, newlyformed planets themselves over the first 100 Myrs, opening up both spectral investigations and also providing a vibrant look into the early dynamical histories of planetary architectures. Here we introduce the Planet Formation Imager (PFI) Project (www.planetformationimager.org) and give initial thoughts on possible facility architectures and technical advances that will be needed to meet the challenging top-level science requirements. © 2014 SPIE.

This work addresses the computation of the set of reachable configurations of linear hybrid automata. The approach relies on symbolic state-space exploration, using acceleration in order to speed up the computation and to make it terminate for a broad class of systems. Our contribution is an original method for accelerating the control cycles of linear hybrid automata, i.e., to compute their unbounded repeated effect. The idea consists in analyzing the data transformations that label these cycles, by reasoning about the geometrical features of the corresponding system of linear constraints. This approach is complete over Multiple Counters Systems (MCS), and is able to accelerate hybrid transformations that are out of scope of existing techniques. [less ▲]

Objectives: Brain mechanisms underlying executive processes are regulated by circadian and sleep homeostatic processes. Furthermore, during sleep deprivation (SD), cognitive performance and neural responses are differentially modulated by a clock gene PERIOD3 polymorphism. Here, we investigated interindividual differences on executive brain responses under SD. Critically, we focused on the circadian evening wake maintenance zone (WMZ), a key time-point for sleep-wake regulation. Methods: Thirty healthy young volunteers, genotyped for the PER3 polymorphism (10 PER3 5/5; 20 PER3 4/4 homozygotes), underwent 42-h SD under constant routine conditions. They performed a 3-back working memory task in 13 successive fMRI sessions. To compare neural activity in the WMZ before and during SD, sessions were realigned according to individual dim light melatonin onset. Results: We tested for a group (PER3 5/5 > PER3 4/4) by session effect (WMZ before vs. during SD). From the fi rst evening WMZ (i.e. during a normal waking day) to the second (i.e. following 40 h of continuous waking), PER3 5/5 individuals relative to PER3 4/4 showed significantly larger increase in responses in the left mid-cingulate, bilateral precuneus and thalamus. Interestingly, these regions are involved in executive processes and arousal regulation (thalamus). Conclusions: These results show that the strong circadian wake-maintenance signal depends on sleep pressure, in a PER3-genotype dependent manner. Interestingly, pronounced genotype differences were observed in the thalamus, an area that compensates potential lower cortical activity under SD. [less ▲]

Validation of the erosion models requires field data. To date, many authors continue to highlight the paucity of accurate field observations and long-term enough studies. The fields observations are often put aside because these measures are difficult to obtain: weighty experimental devices, climatic dependence, . . . Hence the models are evolving and propose refined calculation procedures including for instance the calculation of landscape evolution. The need of field data therefore increases and new measuring strategies should arise. In the centre of Belgium we choose an agricultural watershed quite representative of the local context. It covers 124 ha of loamy soil with more than 90% of arable land and a weak proportion of forest and artificial lands. The slope ranges between 0 and 9%. Instrumentation on the watershed includes meteorological observations and discharge measurement coupled with water sampling at different outlets. The weather data (radiation, temperature, wind velocity, relative humidity and rainfall) and discharge measurement (comparison between Doppler and pressure sensors) will allow us to model the hydrological behaviour of the catchment. Rainfall readings (tipping buckets) are completed with erosivity readings (disdrometer). Erosivity, together with soil data, land use and agricultural practices observations on field, will be used as entry in the Landsoil model. The sediment samplings at 3 points in the catchment will give an insight of the sediment delivery of 3 subcatchments. The Landsoil model calculates the evolution of the DTM through time. This cannot be compared to measurements at the outlet and requires further data collection. Older elevation data and/or archaeological data are a possible source of information even if their precision remains scarce in our context. 1950’s soil surveys are on the contrary really informative since they detail the horizons depth in a spatial way and can be compared to new observation across the watershed. Coupled with unmanned aerial system, they should allow us to test the model performances and improve our knowledge of the spatial patterns of erosion and deposition. [less ▲]

CoRoT and Kepler observations of red giants reveal rich spectra of non-radial solar-like oscillations allowing to probe their internal structure. An important question comes from the observation of mixed modes : When during the star’s ascension on the RGB are mixed-modes more likely to be detectable ? We follow the evolution of a star on the RGB and investigate the effect of its ascension on theoretical power spectrum. Equilibrium models (computed with the code ATON) represent four different stages of a star on the RGB. The mass of the star (1.5M") is in the typical mass range of stars observed by CoRoT and Kepler. We used a non-radial non-adiabatic code to compute the theoretical solar-like oscillations of these models. An important output of these calculations is the theoretical lifetimes of the modes. Then we computed the oscillation amplitudes through a stochastic excitation model. These computations allow us to draw theoretical power spectrum and discuss the possibility to observe mixed-modes at different evolutionary stages on the RGB. We found that structure modifications in a star ascending the RGB have an important impact on theoretical power spectrum of solar-like oscillations. Efficiencies of trapping and lifetimes of mixed modes are indeed strongly affected by this evolution. [less ▲]

Introduction: Donation after circulatory death (DCD) donors have been proposed to partially overcome the organ donor shortage. DCD-LT remains controversial, with reported increased risk of ischemic cholangiopathy leading to graft loss. The authors retrospectively reviewed a single centre experience with DCD-LT in a 9-year period. Patients and Methods: 70 DCD-LT were performed from 2003 to November 2012. All DCD procedures were performed in operative rooms. Median donor age was 59 years. Most grafts were flushed with HTK solution. Allocation was centre-based. Median total DCD warm ischemia was 19.5 min. Mean follow-up was 36 months. No patient was lost to follow-up. Results: Median MELD score at LT was 15. Median cold ischemia was 235 min. Median peak AST was 1,162 U/L. Median peak bilirubin was 31.2 mg/dL. Patient and graft survivals were 92.8% and 91.3% at one year and 79% and 77.7% at 3 years, respectively. One graft was lost due to hepatic artery thrombosis. No PNF or graft loss due to ischemic cholangiopathy was observed in this series. Causes of death were malignancies in 8 cases. Discussion: In this series, DCD LT appears to provide results equal to classical LT. Short cold ischemia and recipient selection with low MELD score may be the keys to good results in DCD LT, in terms of graft survival and avoidance of ischemic cholangiopathy. [less ▲]

Une des missions fondamentales d’une formation universitaire est de permettre aux futurs professionnels d’identifier et de traiter efficacement les informations nécessaires aux prises de décisions parmi un nombre toujours croissant de documents disponibles. Pour atteindre cet objectif, le recours à l’Evidence-Based Practice (EBP) s’avère une approche méthodologique permettant d’acquérir les savoirs et savoir-faire requis pour, notamment, la recherche d’informations probantes. L’EBP doit donc logiquement faire partie de la formation initiale des futurs orthophonistes en restant en adéquation avec les besoins et pratiques des professionnels. À cette fin, il est important d’identifier les questions que se posent les cliniciens dans leur pratique quotidienne, la manière dont ils trouvent des réponses et s’ils ont recours ou non aux données issues de la recherche scientifique. Une enquête a été lancée en mai 2012 auprès d’orthophonistes travaillant en Communauté française de Belgique. La présente communication exposera les principaux résultats, recueillis auprès de 410 orthophonistes, qui conduiront à des pistes d’action pour l’enseignement universitaire et la formation continue.

Background: Donation after circulatory death (DCD) donors > 55 years are usually not considered suitable for liver transplantation (LT). At our institute, age is not an absolute exclusion criterion to refuse DCD liver grafts. We retrospectively compared the transplant outcome of patients receiving older DCD liver grafts to the younger ones. Methods: 70 DCD liver transplants have been performed from 2003 to 2012, which includes 32 liver grafts from younger donors <55y (group A), 20 between 56 and 69 years (group B), and 18 from older donors ≥70 years (group C). The three groups were compared in terms of donor and recipient demographics, procurement and transplantation conditions, peak laboratory values during the first post-transplant week and results at one and three years. Results are expressed as median IQR. Results: No difference other than age in donor and recipient characteristics as well as procurement conditions was noted between both groups. Median donor age of the group A was 44 (38-45) years, in group B 62 (60-64) years and 73 (71-75) in group C. Median primary warm ischemia time (WIT) were 20 (17-22), 21 (19-25) and 19 (16-23) min, respectively (NS). Median cold ischemia time (CIT) was 236 (229-294), 245 (227-290) and 210 (195-277) min, respectively (NS). Peak AST (UI/ml) was 1162 (1072-3971), 1416 (1006-2752), and 1067 (902-4037), respectively (NS). There was no primary nonfunction and one patient needed retransplantation for artery thrombosis. Biliary complications occurred similarly in both groups, without graft loss secondary to ischemic cholangiopathy. Graft and patient survivals were not different at one and three years. Conclusion: This study shows comparable results between DCD liver transplants from younger and older donors. Therefore donor age >55 years should not be a contraindication to DCD liver transplantation if other donor risk factors (such as WIT, CIT) are minimized. [less ▲]

We present a brief summary of what is currently known about white dwarf stars, with an emphasis on their evolutionary and internal properties. As is well known, white dwarfs represent the end products of stellar evolution for the vast majority of stars and, as such, bear the signatures of past events (such as mass-loss, mixing phases, loss and redistribution of angular momentum, and thermonuclear burning) that are of essential importance in the evolution of stars in general. In addition, white dwarf stars represent ideal testbeds for our understanding of matter under extreme conditions, and work on their constitutive physics (neutrino production rates, conductive and radiative opacities, interior liquid and solid equations of state, partially ionized and partially degenerate envelope equations of state, diffusion coefficients, line broadening mechanisms) is still being actively pursued. Given a set of constitutive physics, cooling white dwarfs can be used advantageously as cosmochronometers. Moreover, the field has been blessed by the existence of four distinct families of pulsating white dwarfs, each mapping a different evolutionary phase, and this allows the application of the asteroseismological method to probe and test their internal structure and evolutionary state.

Background: There is a controversy on the possibility to increase the organ donor pool by donation-after-circulatory-death (DCD) and the possible decrease in donation-after-brain-death (DBD) by DCD programs. Our aim is to report the DCD experience at the University Hospital of Liege, Belgium, from 2002 through 2012, in a donor region of about 1 million inhabitants. Methods: The prospective organ donor and recipient databases were retrospectively reviewed. Results: 94 and 331 procurements were performed from controlled DCD and DBD donors in the time period, respectively. DCD donors contributed to 22.1% of the deceased donor (DD) organ procurement activity from Jan 2002 to Dec 2012, and up to one-third annually since 2009. DCD liver and kidneys contributed 23.7% and 24.2% of the DD liver and kidney transplantation activity, respectively. There was no decrease of the DBD procurement in the study period. In 2012, overall 54 DD were procured in the Liege region, reaching a high procurement activity.Conclusions: Controlled DCD donors are a valuable source of transplantable liver and kidney grafts, and in our experience do not adversely affect DBD organ procurement activity.

The global description of a nonlinear system through the linear Koopman operator leads to an efficient approach to global stability analysis. In the context of stability analysis, not much attention has been paid to the use of spectral properties of the operator. This paper provides new results on the relationship between the global stability properties of the system and the spectral properties of the Koopman operator. In particular, the results show that specific eigenfunctions capture the system stability and can be used to recover known notions of classical stability theory (e.g. Lyapunov functions, contracting metrics). Finally, a numerical method is proposed for the global stability analysis of a fixed point and is illustrated with several examples. [less ▲]

Observations from space with CoRoT and Kepler have revealed the rich pulsation spectra that characterize the long period hot B subdwarf (sdB) pulsators of the V1093 Her type. These evolved and compact helium core burning stars can develop low amplitude oscillations with periods in the range ∼ 1 − 4 hours that correspond to low degree, mid to high order g-modes. These modes have the property to penetrate deep inside the star, down to the boundary of the central convective core. They are consequently particularly interesting as asteroseismic probes. Here we briefly review how the g-modes behave in sdB stars, focusing in particular on the seismic signatures coming from the core itself. We also briefly summarize the first seismic results obtained from space data in pioneering efforts to exploit the potential of long period sdB pulsators as deep probes of the core structure.

The determination of the location of the theoretical ZZ Ceti instability strip in the log g − Teff diagram has remained a challenge over the years, due to the lack of a suitable treatment for convection in these stars. We report here a detailed stability survey over the whole ZZ Ceti regime, including the very low masses where three pulsators have recently been found. We computed to this aim 29 evolutionary sequences of DA models with various masses and chemical layering. These models are characterized by the so-called ML2/α=1.0 convective efficiency and take into account the important feedback effect of convection on the atmospheric structure. We pulsated these models with the Liege nonadiabatic pulsation code MAD, which is the only one to conveniently incorporate a full time-dependent convection treatment and, thus, provides the best available description of the blue edge of the instability strip. On the other hand, given the failure of all nonadiabatic codes to account properly for the red edge of the strip, including MAD, we tested the idea that the red edge is due to energy leakage through the atmosphere. Using this approach, we found that our theoretical ZZ Ceti instability strip accounts remarkably well for the boundaries of the empirical strip. [less ▲]

The mixed symmetric positive and negative parity baryons are described in a similar way in the $1/N_c$ expansion method of QCD by using a procedure where the permutation symmetry is incorporated exactly.

L’admissibilité d’une preuve, à savoir la vocation à être prise en considération comme élément de preuve, s’apprécie de manière différente selon qu’il s’agit d’un litige en matière pénale ou en matière civile au sens large. On distingue le système de la preuve libre (matière pénale) et celui de la preuve réglementée (matière civile). L’admissibilité est une question de fond. La question de l’admissibilité des preuves est, depuis plusieurs années, dominée par la jurisprudence de la Cour de cassation initiée par le célèbre arrêt Antigone du 14 octobre 2003, et selon laquelle les preuves irrégulièrement obtenues sont désormais admissibles, sauf si certains vices sont constatés. La circonstance qu’une preuve ou un élément de preuve a été obtenu illicitement n’entraîne pas l’exclusion de la preuve, même si cette irrégularité consiste dans une violation de droits fondamentaux garantis par les Conventions internationales ou la Constitution. Si le vice dans l’obtention de la preuve produite aux débats n’est pas sanctionné de nullité par la loi, c’est au juge qu’il appartient d’apprécier les conséquences de l’irrégularité sur la recevabilité de ce moyen de preuve : celui-ci ne sera pas pris en considération par le juge pour forger sa conviction si l'irrégularité commise a entaché la fiabilité de la preuve ou si elle compromet le droit à un procès équitable. L’arrêt de la Cour de cassation du 10 mars 2008 a, selon la grande majorité des commentateurs, étendu la jurisprudence Antigone à la matière civile, réalisant ainsi une unification de la jurisprudence afférente à ce question. Que le procès soit civil ou pénal, le droit au procès équitable et le principe de proportionnalité se sont substitués au principe de la légalité de la preuve. La tâche du juge s’en trouve complexifiée mais en contrepartie, il dispose de plus de moyens de réconcilier la vérité vraie et la vérité déclarée. Cette jurisprudence a été adoptée sous l’influence des droits étrangers. Le droit comparé révèle que d’autres systèmes juridiques considèrent que la justice serait parfois bien plus discréditée par un refus de prendre en considération des éléments de preuve recueillis de manière illégale que par leur admission et confient au juge le pouvoir de veiller à préserver cette image de la justice en sauvegardant l’équité du procès.

The sympatric relationship between humans and other primates in interface zones is a contemporary widespread phenomenon. The expanding landscapes anthropization leads to an intensification of human-other primate interactions ranging from conflict to co-operation scenarios. Our study investigated the commensal relationships between long-tailed macaques and humans at the tourist Padangtegal Monkey Forest. We present here results related to human-macaque interactions and local people’s perceptions and attitudes towards the latter. We used ethological methods to quantify the nature of the interactions and we conducted a questionnaire survey to identify the macaques’ status in local public opinion. 99 respondents (62 males and 37 females) were selected in a radius of 2km around the Monkey Forest. Perceptions and attitudes were explicitly measured on self-reports and were attributed to a 4 point score. Macaques interacted with humans for 1.1% of their activity budget and these interactions were mostly aggressive (0.6%), food-related (0.4%) or neutral (0.1%). 80% of the aggressive interactions were initiated by humans but the majority aimed at protecting crops and properties from macaques’ incursions. Overall, most of the respondents had positive perceptions and attitudes towards macaques, except neighbouring landowner farmers who suffered from crop damage. Despite nuisances caused by macaques, the majority of the interviewees reported to derive compensatory economic and cultural benefits from their relationships with macaques. The religious and economic contexts might explain the high tolerance level towards macaques that represents a source of hope for a sustainable coexistence, although some management strategies minimizing crop damage still need to be reinforced.

The determination of nitrogen isotopic ratios in solar system objects is important for a good understanding of their origin. The measurements of [SUB]14[/SUB]N/[SUB]15[/SUB]N isotopic ratio done so far in various solar system objects and molecules have revealed a great diversity (from 50 to 441), all of them, except Jupiter, being enriched in [SUB]15[/SUB]N compared to the protosolar nebula. Different explanations have been proposed to explain this enrichement. One of them suggests that these differences reflect the different interstellar N reservoirs from which N-bearing molecules are originating (Hily-Blant et al., 2013). These authors, from observations of H[SUB]13[/SUB]CN and HC[SUB]15[/SUB]N in two prestellar cores, suggest that the molecules carrying the nitrile- (-CN) functional group would be more enriched in [SUB]15[/SUB]N than the molecules carrying the amine (-NH) functional group. Comets are interesting targets to test this theory because they contain both HCN and NH[SUP]3[/SUP] molecules. So far the [SUB]14[/SUB]N/[SUB]15[/SUB]N ratio has only been measured in CN (Arpigny et al., 2003; Manfroid et al., 2009) and HCN (Bockelée-Morvan et al., 2005, 2008) in comets, leading for both species to [SUB]14[/SUB]N/[SUB]15[/SUB]N ≈ 150. Our work aimed at measuring the [SUB]14[/SUB]N/[SUB]15[/SUB]N isotopic ratio in NH[SUP]2[/SUP], which comes from NH[SUP]3[/SUP]. We have determined accurately the wavelengths of [SUB]15[/SUB]NH[SUP]2[/SUP] emission lines with the AILES beamline spectrometer at synchrotron SOLEIL by Fourier transform spectroscopy. The analysis of this spectrum has permitted to extract the [SUB]15[/SUB]NH[SUP]2[/SUP] emission lines wavelengths and to search for [SUB]15[/SUB]NH[SUP]2[/SUP] cometary emission lines. Thanks to a collection of spectra of 12 different comets obtained from 2002 to 2011 with the UVES spectrometer at the VLT ESO 8-m telescope (Manfroid et al., 2009), it has been possible to search for [SUB]15[/SUB]NH[SUP]2[/SUP] emission lines with a high sensitivity. We will present the results obtained from these data. Arpigny et al., Science, 301, 1522-1525, 2003 Bockelée-Morvan et al., in Comets II, ed. M. C. Festou, H. U. Keller, & H. A. Weaver (Tucson: Univ.

Oxygen is an important element in the chemistry of the solar system objects given its abundance and its presence in many molecules including H2O 80% of cometary ices). The analysis of oxygen atoms in comets can provide information not only on the comets themselves but also on the solar system. These atoms have been analyzed using the 3 forbidden oxygen lines [OI] observed in emission in the optical region at 5577.339 Å (the green line), 6300.304 Å and 6363.776 Å (the red lines) (Swings, 1962). Our analysis is based on a sample of 12 comets of various origins. The observing material is made of 53 high signal-to-noise spectra obtained with the high-resolution UVES spectrograph at the ESO VLT from 2002 to 2012 (Manfroid et al, 2009). After noticing that the green line is blended with one C2 line, we built synthetic spectra of C2 for each observing circumstances and we subtracted its contribution to the cometary spectra in order to ensure the decontamination of the 5577 Å line. Then, we measured the intensity of the 3 [OI] lines at different heliocentric distances. By comparing the green to red lines ratio (G/R) with the Bhardwaj & Raghuram (2012) effective excitation rates, we found that H2O is the main parent molecule when the comet is observed at 1 au. When the comet is located beyond 2.5 au from the Sun, CO2 also contributes to the production of oxygen. Studying forbidden oxygen lines could be a new way to estimate the abundances of CO2 in comets, a very difficult task from the ground (Decock et al. 2013). In order to estimate the effect of the quenching on our results, we analyzed the evolution of the G/R ratio at different nucleocentric distances. For nearby comets, we divided the extended 2D spectrum into several zones in order to analyze the oxygen lines as close as possible to the nucleus (down to ~10 km for the closest comets). Their analysis will allow us to study the link of the oxygen lines with the nucleocentric distance. We found a clear variation of the G/R ratio close to the comet nucleus that is in agreement with a contribution from CO2 as predicted by Raghuram & Bhardwaj (2013). [less ▲]

Objectives: To investigate the epidemiological determinants responsible for the high number of anthropophilic dermatophytes received by the National Reference Center for Mycosis of Liege (NRCL) during the year 2012. To perform a genotypic characterization by the Diversilab® system focusing on the two main isolated species, Microsporum audouinii and Trichophyton violaceum. To present a preliminary study preceding the national survey launched in 2013. Methods: A total of 51 strains of M. audouinii (50 clinical + 1 reference (ref.) strains) and 15 strains of T. violaceum (14 clinical + 1 ref. strain) originating from different locations through Belgium were included in the study. The fungal strains were first cultivated on Malt agar, then sub-cultured in Sabouraud liquid medium (Fluka). The grown mycelium was processed for DNA extraction following recommendations of the manufacturer (Ultra Clean® DNA Microbial isolation kit, MoBio laboratories). Genotypic analysis was performed using the DiversiLab® system (BioMérieux) for DNA fingerprinting and analysis. Results: Regarding M. audouinii, four different genotypic groups of strains were separated. Group 1 includes 11 strains and is only found in the Liège surroundings. Group 2 includes only one strain with little differences compared to group 1 and collected from the Liège area. These two groups may be related to each other. Group 3 contains 36 strains and the reference strain. This genotype is distributed in different Belgium locations. The last group, group 4, contains only 3 isolates sharing low similarities in comparison with the 3 other groups. Concerning T. violaceum, 6 different genotypic groups with a mixed geographical distribution were determined. Group 1 includes 8 clinical isolates and the ref. strain. The other five isolates are all different and seem not to be related to each other. Conclusion: The automated typing DiversiLab® system proved to be an easy and efficient method to investigate the molecular epidemiology of dermatophytes infections. Preliminary results of the study show that, through Belgium, several groups of isolates co-exist for M. audouinii and T. violaceum providing evidence of genetic heterogeneity. This variation can be related to acquired mutations due to environmental adaptation. Further investigations are necessary to better understand the impact of this genotypic variation. [less ▲]

On May 4 2013, Pluto passed in front of a 14 star and the shadow was well observed from multiple occultation groups. This paper presents results from the three light curves observed at Las Cumbres Observatory Global Telescope Network (LCOGT) from their Cerro Tololo site. The three LCOGT telescopes have 1.0 m apertures and used identical frame-transfer cameras. The cameras currently have a 2 second readout time therefore autonomous observations were scheduled with different exposure times to give good time resolution of the event. We will present results of this occultation and compare occultation results from 1988 to 2013 with volatile transport models. [less ▲]

We performed high-dispersion near-infrared spectroscopic observations of comet C/2010 G2 (Hill) at 2.5 AU from the Sun using NIRSPEC (R ~ 2.5x10^4) at the Keck II telescope on UT 2012 Jan 9 and 10. The comet had been in outburst. Over the two nights of our observations, prominent emission lines of CH4 and C2H6 along with weaker emission lines of H2O, HCN, CH3OH and CO were detected. The gas production rate of CO was comparable to that of H2O. The mixing ratios of CO, HCN, CH4, C2H6, and CH3OH with respect to H2O are higher than those for normal comets by a factor of five or more. Hyper-volatile species such as CO and CH4 were enriched in the coma of comet Hill suggesting that the sublimation of these hyper-volatiles could sustain the outburst of the comet. Based on a comparison with optical observations, some fraction of water in the inner coma existed as icy grains. Those icy ice grains were likely ejected from nucleus by the sublimation of hyper-volatiles. [less ▲]

Objective: Jumper’s knee is a frequent chronic overuse syndrome of the upper part of the patellar tendon. Platelets contain lots of growth factors which could enhance the healing process of tendons. Infiltration of platelet-rich plasma (PRP) could be a new therapy for such chronic tendinopathies. Materiel and methods: Twenty patients with chronic upper patellar tendinopathy were enrolled. Assessments were made before infiltration of PRP, and 6 weeks and 3 months after the infiltration, using a 10-point Visual Analogic Scale, clinical examinations with a pressure algometer, algofunctional scores (IKDC and VISA-P), functional assessments (isokinetic and optojump evaluations) and imagery (ultrasounds and MRI). The PRP was obtained with an apheresis system (COM.TEC, Fresenius). Six millilitres of PRP were injected without local anaesthetic. One week after infiltration, patients started a standardised sub-maximal eccentric reeducation. Results: Pain during daily activities significantly decreased with time (especially after 6 weeks and continued to a lesser extend up to 3 months). During functional evaluation, it decreased as well, but without significant functional improvement. No improvements in the imagery measurements were observed. Younger patients seemed to be more susceptible to have an improvement of pain by the PRP infiltration. Discussion: This study demonstrates that a local infiltration of PRP associated with a submaximal eccentric protocol is efficient to improve symptoms of chronic jumper’s knee in patients non-responsive to classical conservative treatments.
