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. [less ▲]

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. [less ▲]

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. [less ▲]

Depuis plus d'une dizaine d'années, de nombreux auteurs ont décrit les rôles des tuteurs dans les dispositifs de formation en ligne (Depover et al, 2011 ; Salmon, 2000). La "présence" et les interventions de ces derniers s'avèrent un facteur important dans l'efficacité de tels dispositifs, qu'il s'agisse de maintien de la motivation des apprenants ou du processus d'apprentissage. La variété des méthodologies mises en œuvre dans les scénarios de formation (apprentissage collaboratif, coopératif, individuel...) entraînent des modalités d'interaction différentes entre e-tuteur et apprenants. Se basant sur les étapes de formation au e-tutorat décrites par Denis (2003), un processus original de formation de e-tuteurs est proposé afin de rencontrer la diversité et l'adéquation des profils à adopter selon le contexte considéré. Le scénario de formation au e-tutorat recourt au principe d'isomorphisme en pédagogie (Leclercq, 1998). Outre des apports théoriques relatifs à la problématique traitée et une approche réflexive sur cette dernière, les formés sont amenés à vivre différentes situations d'animation qui pourront (ou non) les inspirer dans leurs futures pratiques de tutorat à distance. Par ailleurs, la formation met l'accent sur le respect d'une triple concordance entre les compétences visées, les activités mises en place et les modalités d'évaluation. [less ▲]

Introduction : Transforming growth factor-beta-induced protein ig-h3 (TGFBI) is extracellular matrix component known to be important for cell-collagen interaction. We and others have reported elevated expression of TGFBI in sev- eral human cancers, where its role remains controversial. Aim Current study aims at clarifying the function of TGFBI to date. Methods &Results : CRC-LM and in liver metastases originating from breast, lung and pancreatic tumors. We have next focused on func- tional aspects and have silenced TGFBI expression in SW1222 human colorectal carcinoma cells. The suppression of TGFBI protein led to a marked decrease in cell migration (-70%) and proliferation (-30%) in vitro. To study the effects in vivo we have developed a novel animal model of colorectal carcinoma based on chicken chorioallantoic membrane (CAM) that mimics human CRC-LM. TGFBI silencing resulted in 50% reduction of tumor volume in the CAM tumor model. Notably, the tumors displayed a marked inhibition of vascularization, suggesting an additional anti-angiogenic effect. Indeed, SW1222 cells silenced for TGFBI expression secreted lower levels of VEGFA in vitro. Finally, we have investigated if TGFBI can be used as systemically reachable target for antibody-drug delivery. For this purpose we have The in vivo data demonstrated that TGFBI is an accessible tumor target. Conclusions : Taken together, the present study shows that TGFBI is essential for promoting the development of CRC- LM and therefore represents a promising target for designing novel therapeutic approaches.

AIM : FDG uptake has been shown to predict the outcome in large series of patients with hepatocarcinoma (HCC) in Asia, but few data are available regarding European populations. Our aim was to evaluate the prognostic value of pretreatment FDG PET-CT in patients treated by liver transplantation. Methods: We retrospectively analyzed the data of 27 patients (24 M and 3 W, mean age 58 ± 9 years). The mean follow-up was 26 ± 18 months (min 1 month, max 66 months). All patients had an FDG PET-CT before the transplantation. The FDG PET/CT was performed according to a standard clinical protocol: 4 MBqFDG/kg body weight, uptake 60 min., low-dose non-enhanced CT. We measured the SUVmax and SUVmean of the tumor and the normal liver. The tumor/liver activity ratios (RSUVmax and RSUVmean) were tested as prognostic factors and compared to the following conventional prognostic factors: MILAN, CLIP, OKUDA, TNM stage, alphafoetoprotein level, portal thrombosis, size of the largest nodule, tumor differentiation, microvascular invasion, underlying cirrhosis and liver function. Results : The DFS was 87.2% at 1y and 72.1% at 3y. The OS was 85.2% at 1y and 80.7% at 3y. According to an univariate Cox model, RSUVmax, RSUVmean and healthy liver were predictors of DFS and RSUVmax, RSUVmean, size of the largest nodule, CLIP, liver involvement>50%, and healthy liver predicted the OS. According to a multivariate Cox model, only RSUVmax predicted DFS and RSUVmax and liver involvement>50% predicted OS. An ROC analysis of the ratios showed that the 1.15 cut-off for RSUVmax was best for predicting both the DFS (Cox regression:HR 14.4, p=0.02) and OS (HR 5.6, p=0.049). The Kaplan-Meier curves and Logrank tests confirmed those results. Even though the MILAN criteria alone were not predictive, it is worth noting that none of the patients outside the MILAN criteria and with RSUVmax<1.15 relapsed. Conclusions: The RSUVmax is a strong prognostic factor for recurrence and death in patients with HCC treated by liver transplantation with a cut-off value of 1,15. further prospective studies should test whether the metabolic index should be systematically included in the preoperative assessment.

Aim: Results of donation after circulatory death (DCD) liver transplantation (LT) are impaired by ischemic bile duct lesions caused by procurement warm ischemia. Donor age is a risk factor in deceased donor LT, and particularly in DCD-LT. At the authors institute, age is not an absolute exclusion criterion to discard DCD liver grafts, controlled DCD donors receive comfort therapy before withdrawal, and cold ischemia is minimized. The aim of the present study was to report on the results of the first 10 years of this experience, and particularly on graft survival and the rate of post-transplant biliary complications, according to DCD donor age. 
 Methods: The authors retrospectively studied a consecutive series of 70 DCD-LT performed from 2003 to 2012, with at least one year of follow-up. This series was divided according to donor’s age, including 32 liver grafts from donors <55years, 20 between 56 and 69 years, and 18 from older donors >69 years. The three groups were compared in terms of donor and recipient demographics, procurement and transplantation conditions, peak laboratory values during the first post-transplant 72 hours, and results at one and four years. Median follow-up was 43 months. 
 Results: Overall graft survival was 98.5%, 91.4% and 69.5% at 1 month, 1 year and 4 years, respectively, without graft loss secondary to ischemic bile duct lesions. Cancer was the primary cause of graft loss and patient death. No difference other than age was noted between the three groups in donor and recipient characteristics, and in procurement conditions. There was no primary non-function but one patient needed re-transplantation for artery thrombosis. Biliary complications occurred similarly in the three groups. Graft and patient survival rates were not different at one and four years between the three groups. During the study period, there was an increasing liver procurement and transplantation activity, and in 2012, 30% of performed LT were DCD-LT, allowing a mean LT waiting time of 66 days. 
 Conclusions: This study shows comparable results between controlled DCD-LT from younger and older donors. Donor age >50 years should not be a contraindication to DCD-LT if other donor risk factors (such as warm and cold ischemia time) are minimized. DCD-LT with short cold ischemia may provide a significant source of liver grafts, decreasing waiting time. [less ▲]

Introduction : Tumor heterogeneity is a major obstacle for developing effective anti-cancer treatments. Recent studies have pointed at large stochastic genetic heterogeneity within cancer lesions, where no pattern seems to exist that would enable a more structured targeted therapy approach. Aim : Because to date no similar information is available at the protein (phenotype) level, we aimed at characterising the proteomic heterogeneity in human colorectal carcinoma (CRC) liver metastases. Methods & Results : We employed MALDI imaging-guided proteomics and explored the heterogeneity of extracellular distribution of over 1000 proteins we found unexpectedly that all liver metastasis lesions displayed a reproducible, zon- ally delineated, pattern of functional and therapeutic biomarker heterogeneity. Peritumoral region featured elevated lipid metabolism and protein synthesis, the rim of the metastasis displayed increased cellular growth, movement and drug metabolism whereas the center of the lesion was characterized by elevated carbohydrate metabolism and DNA- repair activity. From the aspect of therapeutic targeting zonal expression of known and novel biomarkers was evident, reinforcing the need to select several targets in order to achieve optimal coverage of the lesion. Finally we highlight two novel antigens, LTBP2 and TGFBI, whose expression is a consistent feature of CRC liver metastasis. Conclusions : proteome heterogeneity has a distinct, organized, pattern. This particular hallmark can now be used as a part of the strategy for developing rational therapies based on multiple sets of targetable antigens. [less ▲]

Topical application of insecticidal compounds allows directly exposing these substances on insect tissues and measuring their toxicity while ignoring many factors. However, this technique remains difficult to apply on mosquito larvae considering their aquatic lifestyle. Micro-injection could be used for the direct deposition of toxic compounds in the larvae. Capillaries exhibiting an injection tip with an external diameter of 0.5 mm have been designed from silica tubes. For each treatment, a capillary is mounted on a pump connected to a flow rate regulator. Culex quinquefasciatus larvae were injected with 10^7 spores/ml of entomopathogenic fungi (Aspergillus clavatus, Metarhizium anisopliae, Metarhizium sp.). Mortalities were recorded daily during 72h. The distribution of spores stained with methylene blue and injected into the body of larvae was also observed according to the system described. Results showed that spores were distributed over the whole body. The injection of Aspergillus clavatus, Metarhizium anisopliae and Metarhizium sp spores induced corrected mortalities of 62%, 53% and 57% after 72h, and differed statistically from control groups. Finally, post-mortem emergences of filaments from dead larvae were observed in the case of the three fungal strains confirming spore viability. Injection of inactivated spores (or inert bodies of similar size) could help to reject the hypothesis of a response due to the presence of foreign bodies. [less ▲]

We briefly introduce hot subdwarfs and their evolutionary status before discussing the different types of known pulsators in more detail. Currently, at least six apparently distinct types of variable are known among hot subdwarfs, encompassing p- as well as g-mode pulsators and objects in the Galactic field as well as in globular clusters. Most of the oscillations detected can be explained in terms of an iron opacity mechanism, and quantitative asteroseismology has been very successful for some of the pulsators. In addition to helping constrain possible evolutionary scenarios, studies focussing on stellar pulsations have also been used to infer planets and characterize the rotation of the host star.

Hot B subdwarfs (sdB) are hot and compact helium core burning stars of nearly half a solar mass that can develop pulsational instabilities driving acoustic and/or gravity modes. These evolved stars are expected to be chemically stratified with an almost pure hydrogen envelope surrounding a helium mantle on top of a carbon/oxygen enriched core. However, the sdB stars pulsating in g-modes show regularities in their observed period distributions that, surprisingly (at first sight), are typical of the behavior of high order g-modes in chemically homogeneous (i.e., non-stratified) stars. This led to a claim that hot B subdwarfs could be much less chemically stratified than previously thought. Here, we reinvestigate trapping effects affecting g-modes in sdB stars. We show that standard stratified models of such stars can also produce nearly constant period spacings in the low frequency range similar to those found in g-mode spectra of sdB stars monitored with Kepler.

This research aims to formalize the spatiotemporal relationships of membership between individuals and the groups to which they belong. Specifically, we analyze how the membership to a community evolves over time considering past, present and future connections. The framework developed for this research is presented using an ontological approach. We demonstrate a specific domain ontology application for spatiotemporal membership using BFO2, an updated version of the Basic Formal Ontology. Key to this work is the representation of membership, modeled through different kinds of mereological relations possible with a group, for example, pre-member, active member, and alumni that capture how membership evolves and changes over time. The semantic web rule language (SWRL) is used to express the different spatiotemporal events that relate to membership and their consequences on membership such as subscription, graduation and reunion events. Mobility events are also included in the model. SWRL supports reasoning using the ontology and studying the evolution of membership between people and their various groups. We use the environment of a university community as an exemplar to develop and test the formalizations. However, the ideas are generalizable to a wide range of spatiotemporal domains, for example, these ideas hold for citizenship modeling or for consumers shopping at certain retail chains. The study of the evolution of membership connections between these entities and groups lends important insights for many different kinds of event planning. [less ▲]

A six and a half year (January 2005 to May 2011) comparison of CO2 concentration observations has been performed at Jungfraujoch, Switzerland and the city of Bern using two different measurement techniques run by the University of Bern (UBE) and the University of Liege (UL). The UBE systems at Jungfraujoch and Bern are both combined systems for atmospheric oxygen and CO2 measurements. The cryogenically dried air is analysed for CO2 with a Maihak analyser based on the broad-band infrared absorption technique. The measurement frequency is every second but the final reported data are averages of six minute periods. UL is measuring the solar infrared spectrum since 1950 at Jungfraujoch. On its way through the atmosphere, the solar spectrum is modulated depending on the abundant gas species and their amount in the column. Since some gases like CO2 absorb the solar infrared radiation at particular wavelengths and the extinction is proportional to the gas concentration, it is possible to determine the gas concentration in the column above the sensor. At the conference, we will present the three observational records for the six and a half year period. The results show for all three records a distinct, but different seasonality. The seasonalities of the UL and UBE record at Jungfraujoch are lower than the seasonality in the city of Bern, i.e. 4.5 ppm per year and 9 ppm per year for the column and the in- situ record respectively, whereas the seasonality in the city of Bern is 31 ppm per year. Also the maxima and minima of the Jungfraujoch measurements are delayed by several weeks compared to the measurements in the city of Bern. The annual increase of the CO2 concentration of the UBE and UL records of Jungfraujoch are in good agreement with 1.94 ppm per year and 1.90 ppm per year, respectively. The annual increase of the CO2 concentration at the urban site is a bit higher at 2.01 ppm per year. [less ▲]

This paper presents an efficient method for the finite element assembly of high order Whitney elements. We start by reviewing the classical assembly technique and by highlighting the most time consuming part. Then, we show how this classical approach can be reformulated into a computationally efficient matrix - matrix product. We also address the problem of the basis orientation by considering more than one reference space. We conclude by presenting numerical results on a wave guide problem. [less ▲]

We present several examples of partial mode identification for rapidly pulsating subdwarf B stars on the basis of multi-colour observations. Three targets (V391 Per, Balloon 090100001, and EC 11583−2708) were analysed from multi-colour photometry, while studies were conducted from time-series spectrophotometry for two further stars (EC 20338−1925 and EC 01541−1409). In all cases, periodicities strongly dominating the frequency spectrum are associated with radial modes, indicating a clear hierarchy according to visibility when integrating over the visible disk of the star.

Objectifs En Belgique, les mesures de prévention médicalisées restent inéquitablement distribuées dans plusieurs domaines (vaccins, dépistages, conseil cardio-vasculaire, etc.). Une recherche antérieure au moyen d’une échelle d’attitude a mis en évidence trois facteurs pouvant modeler l’attitude des médecins généralistes (MG) envers la prévention : 1. Evaluation de pratique. 2. Sentiment de responsabilité envers la santé des patients. 3. Compétences professionnelles particulières (CPP) : références scientifiques, positionnement dans le système de soins, délégation de tâches à des paramédicaux. Cette étude a cherché à établir des profils de MG par rapport à la prévention, en croisant les scores sur ces trois facteurs et les variables sociodémographiques. Méthode Les réponses des 457 MG répondants à l’échelle d’attitude ont été soumis à des analyses multivariées, en prenant comme variables dépendantes les scores obtenus sur les trois facteurs, et comme variables indépendantes l’ancienneté, le sexe, la langue, le lieu de pratique, le travail dans un centre de prévention (ONE, planning, PSE), le type de pratique (solo ou divers types d’association). Résultats Le type de pratique est le seul déterminant qui influence les 3 facteurs, avec un gradient des pratiques solo vers les maisons médicales, en passant par les associations mono- puis pluridisciplinaires. Les MG ayant moins de 20 ans de pratique ont de meilleurs scores en évaluation et CPP. Les hommes ont de meilleurs scores en évaluation, et les pratiques urbaines se distinguent en CPP. La langue influence tantôt dans un sens tantôt dans l’autre. Il n’y a pas d’influence du fait de travailler dans un centre de prévention. Conclusion Une diffusion plus large et équitable des actes préventifs passe par la prise en compte de facteurs personnels et organisationnels propres aux MG. Les associations pluridisciplinaires semblent mieux préparées pour atteindre cet objectif. [less ▲]

The challenge of OMNISCIENTIS is to develop a community based odour monitoring and information system to mitigate odour annoyance and to foster citizens’ participation in environmental governance. The core is an information system collecting various data of odour emissions obtained by electronic noses and other sensors, meteorological conditions and observations by citizens acting as human sensors. A specific odour dispersion model is developed to use all this information and provide immediate feedback to all stakeholders. This work presents the architecture of the environmental information system, some first results from odour monitoring and model development and validation. [less ▲]

Detailed seismic studies of hot B subdwarf (sdB) stars using the forward modeling approach provide measurements of their fundamental parameters at very interesting precisions. For instance, masses, radii, and log g values derived this way are typically claimed at ∼ 1 − 2%, ∼ 0.5%, and ∼ 0.1 % precision, respectively. However, this method relies on still imperfect stellar models that contains various uncertainties associated with their inner structure and the underlying microphysics. A signature of these imperfections is the inability of current best-fit seismic models to reproduce all the observed oscillation frequencies at the precision of the observations. Therefore, the question of the accuracy (as opposed to the precision) of the derived parameters obtained from this approach is legitimate. Here, we revisit the question of precision and accuracy based on new, third generation, complete static models of sdB stars developed for asteroseismology and applied to the case of the eclipsing system PG 1336-018. This allows us to evaluate the reliability of the method and quantify the impact of various uncertainties in the stellar models on the derived stellar parameters. Finally, we discuss the intrinsic potential of asteroseismology for precise measurements of stellar parameters and show that we are far from having fully exploited this technique in terms of precision that can, in principle, be achieved.

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 ▲]

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.

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 ▲]

Objectifs Les médecins généralistes (MG) jouent un rôle majeur dans la détection et la gestion des abus de substances. L’étude présentée ici investiguait les facteurs qui influencent leur implication concernant la gestion des abus d’alcool, des drogues illégales, des hypnotiques et des anxiolytiques dans la population belge des 18-65 ans. Méthodes 20 MG ont été interrogés par entretiens semi-directifs dans les régions de Liège et d’Anvers. Le I-Change Model de de Vries a été utilisé pour construire le guide d’entretien et analyser les données récoltées. Résultats Parmi les principaux résultats de l’étude, il ressortait que les MG étaient fortement influencés dans leur approche par leurs propres représentations de l’abus, qui oscillait leurs responsabilités professionnelles envers ces patients et la responsabilité de ces derniers quant à la gestion de leur santé, avec l’idée de faute morale en substrat. En ce sens, l’abus de substance était perçu sur un continuum entre l’abus comme forme de maladie chronique d’une part, et la faute morale d’autre part. L’alcool et le cannabis étaient néanmoins mieux acceptés socialement que les autres substances. Les propres expériences personnelles des MG concernant les abus avaient aussi une incidence sur leur volonté de s’investir avec ces patients. Pour autant, les pratiques multidisciplinaires (notamment au forfait) et l’expérience étaient évoqués comme des facteurs importants quant à l’engagement dans la gestion. Les contraintes temporelles et l’investissement demandé étaient, en revanche, considérés comme des barrières. Conclusion Les facteurs motivationnels apparaissaient centraux dans la décision de s’investir dans la gestion des abus de substances, bien davantage que les connaissances théoriques et les formations qui semblaient plus secondaires. La peur du burn-out s’exprimait donc en substrat. La formation des MG devrait tenir compte de ce souhait de se protéger, afin de favoriser simultanément une approche centrée sur le patient. [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 ▲]

Long-lived chlorine-containing source gases, such as chlorofluorocarbons (CFCs), are transported into the stratosphere where they decompose and cause ozone depletion. Increases in chlorine during the 1970s-1990s resulted in long-term ozone decreases, especially in the polar regions. Following the implementation of the Montreal Protocol, the near-surface chlorine loading was observed to peak in 1993 and, since then, to decrease in line with expectations. After release from source gases in the stratosphere, chlorine mainly forms the reservoir HCl, providing an alternative method for monitoring the progress of the Montreal Protocol. A maximum in stratospheric HCl was observed around 1996, followed by decay at a rate close to 1%/year, consistent with the tropospheric chlorine peak and known transport timescales. However, we will present total column observations from ground-based FTIR instruments which show an unexpected and significant upturn in stratospheric HCl around 2007 in the northern hemisphere. Height-resolved observations from satellite instruments (HALOE, MLS, ACE) confirm this increase and show that it occurs in the lower stratosphere. These observations contrast with the ongoing monotonic decrease of near-surface chlorine source gases. Using 3-D model simulations (TOMCAT/SLIMCAT and KASIMA) we attribute this trend anomaly to a slowdown in the NH atmospheric circulation, causing air in the lower stratosphere to become more aged with a larger relative conversion of source gases to HCl. An important conclusion is that the Montreal Protocol is still on track and will still lead to long-term decreases in stratospheric chlorine. This dynamical variability could also significantly affect the evolution of stratospheric ozone and must be accounted for when searching for signs of ozone recovery. [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.

Cataract is the opacity of the lens, causing impairment of vision or even blindness. Today, a surgery is still the only available treatment. The intraocular lens (IOL) is a polymer implant designed to replace the natural lens in the cataract surgery. However, the bioinert materials could not satisfy the unmet need in the secondary cataract control. Posterior capsular opacification (PCO, or Secondary Cataract), characterized by a thick and cloudy layer of lens epithelial cells (LECs), is the most common postoperative complication. In our research, a bioactive molecule is immobilized onto the conventional acrylic hydrophilic polymer pHEMA (Poly(2-hydroxyethyl methacrylate)) using oxygen plasma treatment followed by deposition. The RGD peptide sequence, being well-known for its ability to promote cellular attachment by binding to integrin receptors, is designed to stimulate the adhesion of LECs on the IOL. Our data show the peptide immobilized biomaterial not only exhibits similar optical property, but also reveals enhanced biological properties in cell adhesion and cell morphology maintenance. By means of surface functionalization of IOL to stimulate LECs adhesion, the secondary cataract could be controlled. [less ▲]

The toxicity of Fyto11, a plant resistance elicitor commercial formulation used to increase the natural resistance of Cucurbitaceae (cucumber, zucchini and melon) and Solanaceae (tomato and sweet pepper) against powdery mildew under greenhouse conditions, has been assessed on several beneficial arthropods: the honeybee Apis mellifera, the predatory miteTyphlodromus pyri, the aphid parasitic wasp Aphidius rhopalosiphi and the aphid predator Episyrphus balteatus. Tested at 0.5% and 1.0% spray dilution on plants, Fyto11 did not lead to significant corrected mortalities for E. balteatus larvae and adult wasps of A. rhopalosiphi, with a maximum of 5.4% mortality. No effects on reproduction capacity of the parasitic wasps were observed. The exposure of T. pyri protonymphs to Fyto11 on glass plates lead to corrected mortalities of 1.1% and 32.6% at 0.5% and 1.0% and to a reduction of female fertility of 9.0% and 25.4%, compared to the control performance. When assessed on the honeybee by contact and oral exposure, Fyto11 did not lead to significant effects, with LD50 estimated as > 10 μg a.i./bee (oral) and 12.5 μg a.i./bee (contact), leading to HQ ratio < 50 and classifying the product at no or low risk for honeybees. These results showed that the product was harmless for all beneficials at the proposed commercial rate, except for T. pyri at 1.0% on glass plates, where the product was rated as slightly harmful. Even if all the beneficial species’ diversity has not been assessed with this product, negative effects on non-target organisms are not expected in field conditions and Fyto11 can be considered as compatible with IPM programs.
