This paper aims at validating pressure and velocity measurements conducted in two physical scale models of an ogee spillway crest operating at heads largely greater than the design head. The design head of the second model is 50% smaller than the one of the first model. No piles effect or air entrance is considered in the study. The velocity field is measured by Large Scale Particle Image Velocimetry. The relative pressure along the spillway crest is measured using pressure sensors. Comparisons of measured velocities between both spillways indicate low scale effects, the scaled-profiles collapsing in most parts of the flow. By contrast, measurements of relative pressure along the spillway crest differ for large heads. A theoretical velocity profile based on potential flow theory and expressed in a curvilinear reference frame is then fitted to the velocity measurements, considered as reference, for extrapolating the velocity at the spillway crest. Comparing the extrapolated velocity at the spillway crest and the velocity expressed from the relative pressure finally emphasizes that bottom pressure amplitudes are overestimated for the large spillway, while an averaging effect might operate for the pressure measurements on the small spillway.

Algorithmic and computer programming in the bachelor’s degree is a course that demands a large involvement of students in performing non-standard exercises. This practical aspect is incompatible with classical ex cathedra course. It is the reason why we implement a blended learning approach much more responsive to students in a bachelor class of Bio Engineering at the Gembloux Agro Bio Tech Faculty (University of Liege, Belgium). This course alternates theoretical classes, take-home lessons with the help of online pedagogical resources and video and debriefing sessions where students have the possibility to benefit from teacher’ support. In doing so, the students are better prepared for the examination. They also gain in confidence and motivation. The teacher no longer simply transmits the knowledge but assists the students in their reflection process and their mastering of programming tools [less ▲]

Parmi ses multiples dispositions tendant à canaliser une France perçue comme expansionniste, le congrès de Vienne a entériné la naissance d’un Royaume uni des Pays-Bas, amalgamant des territoires aujourd’hui répartis entre la Belgique, le Luxembourg et les actuels Pays-Bas. Qu’on y voie une barrière contre la France, une sentinelle plantée au nord ou un boulevard pour l’Europe, les Low countries ont un rôle stratégique majeur. Mais la logique militaire ne peut faire abstraction des hommes et les réalités politiques, religieuses, linguistiques conduiront, en 1830, à la fin d’une expérience que peu de diplomates considéraient d’ailleurs, dès ses prémisses, comme viable. Dans cette contribution, nous entendons faire le point sur la période post-française dans l’actuelle Belgique. En quoi les années 1814-1830 ont-elles été une étape cruciale dans l’affirmation d’une identité nationale ou d’un patriotisme belge ? Pourquoi la politique de Guillaume Ier s’est-elle heurtée, dans les provinces méridionales, à une opposition plurielle et parfois paradoxale ? Pourquoi peut-on dire que les questions de liberté d’enseignement, de liberté religieuse et de liberté linguistique se sont intimement liées pour constituer la matrice des événements de 1830, une matrice alimentée bien sûr également par des revendications de nature économique ?

Like all Herpesviruses VZV expresses two conserved proteins forming the nuclear egress complex (NEC), namely ORF24p and ORF27p, respectively homologous to UL34 and UL31 in HSV-1. Many works described the role of this complex and viral kinases, the Alpha-herpesvirus specific kinase US3p, and hCMV UL97p (conserved in all Herpesviruses and homolog to UL13p in HSV-1), in the nuclear capsids translocation to the cytoplasm. Indeed, using a very complex mechanism, not yet fully characterized, nuclear capsids bud through the internal nuclear membrane, stay briefly in the perinuclear space and finally free the capsids into the cytoplasm through fusion of the primary envelope with the external nuclear membrane. In the cytoplasm, virions acquire the second and last envelopment before being released outside the cells. In order to better characterize the nuclear egress in the context of VZV, we focused our work on the NEC and on both viral kinases ORF47p and ORF66p respectively homologous to HSV-1 UL13p and US3p. By co-immunoprecipitation we identified a protein complex containing ORF24p, ORF27p and both viral kinases and are currently trying to determine the role of each kinase in the formation of this complex. We are also characterizing the phosphorylation status of these proteins depending on ORF66p and/or ORF47p. Immunofluorescence studies of cells infected with a deleted ORF66 or ORF47 virus showed mislocalisation of some viral proteins such as ORF24p as described for HSV-1. Finally electron microscopy analyses are in progress and will help to determine the role of both VZV kinases in the nuclear egress. [less ▲]

Temporal and spatial monitoring of soil water potential and soil water content are necessary for quantifying water flow in the domains of hydrology, soil science and crop production as knowledge of the soil water retention curve is important for solving Richards’ equation. Numerous measurement techniques exist nowadays that use various physical properties of the soil-water complex to record changes in soil water content or soil water potential. Laboratory techniques are very useful to determine static properties of the soil water retention curve, and have been used to show the impacts of hysteresis. Yet, other spatiotemporal dynamics resulting from for example growing root systems, biological activity, periodic tillage and their impact on the soil structure cannot satisfactory be quantified in static setups in the laboratory. ). To be able to quantify the influence of soil heterogeneity, and spatiotemporal dynamics on the soil water retention curve, an in situ approach combining soil moisture and soil water potential measurements could provide useful data. Such an in situ approach would require sensors that can measure a representative part of the soil water retention curve. The volumetric soil water content is often measured using time domain reflectometry, and has gained widespread acceptance as a standard electronic means of volumetric water content measurement. To measure the soil water potential, water filled tensiometers are used in most studies. Unfortunately, their range remains limited due to cavitation. Recently, several new sensors for use under in situ conditions have been proposed to cover a wider range of pressure head: Polymer tensiometers, MPS (Decagon) and pF-meter (ecoTech). In this study, we present the principles behind each measurement technique. Then we present the results of a fully controlled experiment where we compared two MPS sensors, two pF-meter sensors and two POT sensors in the same repacked soil. It allows us to discuss advantages and disadvantages of each method. A CS616 volumetric water content probe was installed to compare in situ measured retention curves with laboratory measured retention curves for each method. [less ▲]

In the present paper, isolated response curves in a nonlinear system consisting of two masses sliding on a horizontal guide are examined. Transverse springs are attached to one mass to provide the nonlinear restoring force, and a harmonic motion of the complete system is imposed by prescribing the displacement of their supports. Numerical simulations are carried out to study the conditions of existence of isolated solutions, their bifurcations, their merging with the main response branch and their basins of attraction. This is achieved using tools including nonlinear normal modes, energy balance, harmonic balance-based continuation and bifurcation tracking, and global analysis. [less ▲]

Holzkirchen full scale dynamic experiments were conducted in the framework of IEA Annex 58 research program with the aim to obtain and apply a high quality experimental dataset for model validation of full scale buildings. A first experiment was conducted in August 2013. Two identical houses were submitted to a side by side experiment, one with blinds up, one with blinds down. That first experience lasted 42 days including an initialization period, a Randomly Ordered Logarithmic Binary Sequence of heat inputs (ROLBS), and a re-initialization followed by a free-float period. A second experiment was conducted in April 2014 in one of the two houses, with higher levels of heating power in the South oriented zones and imposed indoor temperatures in the North oriented zones. Simulations were performed with EES Engineering Equation Solver using simplified RC dynamic models. The discrepancies observed between simulated results and measured data were first explained through a deeper analysis of thermal bridges, a better assessment of solar heat gains and a better assessment of the air duct heat losses. In the second experiment, the results revealed an underestimation of the building transmission heat losses. A candidate explanation might be the air stratification which would enhance heat losses on the ceiling side. A modelization of the upper and lower room air layers was introduced. The resulting simulated indoor temperature profiles were in accordance with the measurements. A complete breakdown of heat losses and heat gains was computed for both houses, using measured temperatures as input data for the simulation. [less ▲]

The seagrass Posidonia oceanica is widely recognized as an effective bioindicator of the health status of Mediterranean coastal waters. Chlorophyll fluorescence measurements, in particular through the Pulse Amplitude Modulated (PAM) fluorometry method, are performed to study aquatic plant ecology and vitality and to assess their responses to diverse stressful factors. However, the current understanding of P. oceanica photosynthetic responses to environmental stresses does only allow scientists to use the PAM-method as a complementary tool to other more-robust monitoring techniques. Consequently, a more in-depth knowledge of the natural causes of variability of P. oceanica photosynthetic responses are a prerequisite to any surveys relying on that time and cost-effective method. In the framework of the STARECAPMED project, this work aimed to determine the influence of several environmental (depth, daytime, season) and plant-specific characteristics (leaf age, leaf part analyzed, epiphytic coverage) on the photosynthetic responses (Y, ETR, RLC) of P. oceanica. Water temperature, irradiance and several biochemical parameters of the seagrass (chl.a, chl.b, C, N, P, micronutrients such as Fe, Cu) were measured as well. The field survey was performed in a pristine meadow in the Calvi Bay, Corsica. Environmental and plant-physiological characteristics deeply influenced P. oceanica photosynthetic responses. As an example, ETR decreased with depth, contrary to Y that mostly increased. ETR was lower in the basal part of leaf blade, and the epiphytic coverage of leaf tips slightly increased their ETR compared to leaf tips cleaned of epiphytes. Depth and leaf part-related variations in RLC were also observed. Because of this natural variability, it appears essential to develop a consensual protocol of chlorophyll fluorescence measurements to publish reliable and comparable results between studies. We therefore notably suggest to perform measurements close to midday, when photosynthetic responses are the highest; at 10-15 m depth in order to avoid, among others, low depth light irradiance variability; on the middle part of the 3rd-4th external leaf, well developed, highly photosynthetic, and little epiphyted. Finally, because P. oceanica fluorescence was correlated with N, P and chl.b leaf contents, the PAM-method could afterwards be used as bioindicator technique, according to the protocol proposed.

Electrical resistivity tomography (ERT) has often been put forward as a promising tool to quantify soil water and solute fluxes in a non-invasive way. In our experiment, we wanted to determine preferential flow processes along a forested hillslope using a saline tracer with ERT. The experiment was conducted in the Houille watershed, subcatchment of the Meuse located in the North of Belgian Ardennes (50˚1’52.6”N, 4˚53’22.5”E). The climate is continental but the soil under spruce (Picea abies (L.) Karst.) and Douglas fire stand (Pseudotsuga menziesii (Mirb.) Franco) remains quite dry (19% WVC in average) during the whole year. The soil is Cambisol and the parent rock is Devonian schist covered with variable thickness of silty loam soil. The soil density ranges from 1.13 to 1.87 g/cm3 on average. The stone content varies from 20 to 89% and the soil depth fluctuates between 70 and 130 cm. The ERT tests took place on June 1st 2012, April 1st, 2nd and 3rd 2014 and May 12th 2014. We used the Terrameter LS 12 channels (ABEM, Sweden) in 2012 test and the DAS-1 (Multi-Phase Technologies, United States) in 2014. Different electrode configurations and arrays were adopted for different dates (transect and grid arrays and Wenner – Schlumberger, Wenner alpha and dipole-dipole configurations). During all tests, we systematically faced technical problems, mainly related to bad electrode contact. The recorded data show values of contact resistance above 14873 Ω (our target value would be below 3000 Ω). Subsequently, we tried to improve the contact by predrilling the soil and pouring water in the electrode holes. The contact resistance improved to 14040 Ω as minimum. The same procedure with liquid mud was then tested to prevent quick percolation of the water from the electrode location. As a result, the lower contact resistance dropped to 11745 Ω. Finally, we applied about 25 litre of saline solution (CaCl2, 0.75g/L) homogeneously on the electrode grid. The minimum value of contact resistance reduced to 5222 Ω. This improved the contact resistance substantially, but complicates the execution of a pulse tracer experiment. To date we did not find any better solution to this problem and we keep searching a way to improve the contact resistance in stony forested soils with very low bulk density. We would like to exchange on these questions with EGU attendees in order to improve the experimental design or point out a new research path for these specific conditions. This could lead to enhance the use of ERT in soils with low density and high stone content. [less ▲]

We present high-resolution Cassini/UVIS (Ultraviolet Imaging Spectrograph) observations of Saturn's aurora during May 2013 (DOY 140-141). The observations reveal an enhanced auroral activity in the midnight-dawn quadrant in an extended local time sector (~02 to 05 LT), which rotates with an average velocity of ~ 45% of rigid corotation. The auroral dawn enhancement reported here, given its observed location and brightness, is most probably due to hot tenuous plasma carried inward in fast moving flux tubes returning from a tail reconnection site to the dayside. These flux tubes could generate intense field-aligned currents that would cause aurora to brighten. However, the origin of tail reconnection (solar wind or internally driven) is uncertain. Based mainly on the flux variations, which do not demonstrate flux closure, we suggest that the most plausible scenario is that of internally driven tail reconnection which operates on closed field lines. The observations also reveal multiple intensifications within the enhanced region suggesting an x-line in the tail, which extends from 02 to 05 LT. The localised enhancements evolve in arc and spot-like small scale features, which resemble vortices mainly in the beginning of the sequence. These auroral features could be related to plasma flows enhanced from reconnection which diverge into multiple narrow channels then spread azimuthally and radially. We suggest that the evolution of tail reconnection at Saturn may be pictured by an ensemble of numerous narrow current wedges or that inward transport initiated in the reconnection region could be explained by multiple localised flow burst events. The formation of vortical-like structures could then be related to field-aligned currents, building up in vortical flows in the tail. An alternative, but less plausible, scenario could be that the small scale auroral structures are related to viscous interactions involving small-scale reconnection. [less ▲]

We report Cassini/UVIS observations of auroral vortices at Saturn propagating from midnight to noon via dawn. The emission in the dawn auroral sector is observed to consist of several detached features that swirl with time. They have a diameter of 6000 km in the ionosphere, which would correspond to plasma vortices in the magnetosphere of 12 to 15 Rs. ENA enhancements are observed simultaneously. However, they do not show any clear vortices. We estimate the velocity of the UV auroral feature to decrease from 85% of rigid corotation (28o/h) in the most equatorward part of the aurora to 68% of rigid corotation (22o/h) in the poleward part and we demonstrate that such velocity gradient could result in swirling auroral features. Particle velocities derived from magnetospheric data in previous studies, confirm large variations of the corotation fraction as a function of radial distance. We suggest that the auroral vortices could be the ionospheric footprints of hot dynamic populations containing strong velocity gradients. Alternatively, we consider another scenario that could generate auroral vortices based on field line deformation from the magnetosphere to the ionosphere, like it is proposed for the Earth. In that case the auroral spiral is the result of some processes that occurred in the transition region between the centers of vortices where strong shear flows existed. Finally, a third possibility is considered, according to which the auroral vortices reported here are the direct optical signatures of the plasma vortical flows in the magnetopause related to Kelvin-Helmholtz instabilities. However, this might be less possible due to the very different spatial scales of the auroral features (12-15 Rs) and the observed plasma vortices in the magnetopause (1 Rs). [less ▲]

Matériels et méthodes : l’étude porte sur un crâne déformé provenant d’Ancón au Pérou, inventorié au Muséum National d’Histoire Naturelle (MNHN) de Paris en 1889. L’étude est géographique, historique, macroscopique et tomodensitométrique. Résultats : situé sur la côte à 40 km au nord de Lima, la capitale du Pérou, le site d’Ancón est un site archéologique de la période lithique, et un lieu de sépulture depuis l’époque Chavín (1250 à 250 av. J.-Chr.). Dès l’époque Chavín, les peuples du Pérou ancien construisaient des centres cérémoniels dirigés par une élite théocratique, et déformaient le crâne des enfants dès les premiers jours de la vie, à l’aide de moyens de pression variés. La déformation du crâne d’Ancón est une déformation antéro-postérieure oblique, brachycéphale, bilobée et asymétrique, sans trépanation ni déformation dentaire associée. C’est une variante bilobée du type Huaura de déformation crânienne, qui est associé aux régions de Chancay-Ancón et Lima. L’étude tomodensitométrique des variations d’épaisseur de la voûte, avec amincissement en regard des zones de pression, a montré que la déformation était intentionnelle, et caractérisée par une pression fronto-pariéto-temporale bilatérale surtout antérieure et dégressive d’avant en arrière, associée à une pression frontale, occipitale, et sagittale médiane. En l’absence de contexte et de datation, l’ancienneté du crâne étudié ne peut pas être précisée au long d’une période de presque trois millénaires, jusqu’à la domination Inca et l’arrivée des Espagnols (1532). Le crâne pourrait appartenir à l’une ou l’autre des cultures successives du site d’Ancón : Chavín, Baňos de Boza o Miramar, Lima, Wari, et Chancay (1200 à 1470), dont les céramiques représentent la déformation bilobée. Le crâne est probablement celui d’une femme âgée de plus de 45 ans à son décès, de statut social élevé, faisant partie de l’élite magico-religieuse, politique et économique dirigeante. L’étude de l’endocrâne a permis d’observer la déformation des veines superficielles et des lobes du cerveau. Il existe des signes de parodonpathie chronique à un stade avancé. Un abcès d’origine dentaire pourrait avoir été la cause du décès. Conclusions et perspectives : en ce qui concerne la pratique des déformations crâniennes, la région d’Ancón-Chancay et de Lima paraît être remarquable à trois égards : par le grand nombre de crânes déformés, par le grand nombre de crânes bilobés, et par la proportion importante de femmes, dont on peut supposer qu’elles étaient nées de familles nobles, et destinées dès l’enfance à faire partie de l’élite théocratique. La reconstitution 3D de l’épaisseur de la voûte crânienne a permis pour la première fois à notre connaissance de caractériser ce type de déformation, et pourrait permettre de reconstituer l’appareil déformateur. Seule la reprise des exhumations programmées sur le site d’Ancón, dans le cadre d’un projet prospectif pluridisciplinaire, pourrait permettre de mieux préciser la proportion d’individus à crâne déformé, la proportion des crânes bilobés, et le sex ratio, dans chaque contexte historique et socio-culturel de ce type de déformation crânienne intentionnelle ; et, peut-être, de retrouver in situ l’appareil déformateur correspondant.

Europe Wide Views (EWV) on Sustainable Consumption is a cross-European citizen consultation providing unique insights into the views of ordinary citizens across Europe on sustainable consumption and policies connected to this complex issue. The consultation took place simultaneously in 11 EU member states on October 25th 2014 and involved 1035 European citizens. Throughout the day, the participating citizens deliberated with fellow citizens and voted on issues relating to future policy-making on sustainable consumption. Overall, EWV was framed as a participatory Technology Assessment (pTA) exercise. Following the hypothesis that TA practitioners do not enough question the design of their projects’ and their own normative assumptions, we suggest to put the consultation we organised in Wallonia (Belgium) to the test. The aggregated results of the consultations point to the fact that “citizens are [now, after the EWV] strongly in favour of policy-makers taking ambitious steps in order to foster a more sustainable consumption in society, and want to personally take action in this process”. Relying on our previous work on dystopia as empowerment, we suggest a self-reflexive experiment to inquire into how much the design of the consultation (including the materials that were circulated) and the messages that we conveyed pictured a threatening present that would lead to an apocalyptic future ‘if nothing was done’, thereby potentially biasing the results that will are to be translated into political recommendations. Our analysis will benefit from cross-breeding future studies and science and technology studies to think afresh invisible normativities induced by pTA of sustainable governance. [less ▲]

In this work, an electricity zone with 100% renewables is simulated to determine the optimal sizing of generation and storage capacities in such a zone. Using actual wind output data, the model evaluates the economic viability of a power-to-fuel storage technology that combines water electrolysis, CO2 capture and methanol synthesis. The main advantage of using methanol as an energy carrier is that liquid fuels are suitable for (long-term) energy storage thanks to their high energy density. The levelized electricity cost projection by 2050 equals 83.4 €/MWh in the base case configuration. The effects of storage round-trip efficiency and the storage unit lifetime are quantified and their impacts on the electricity cost discussed. Additional benefits of using methanol as a fuel substitute may be taken into account in further work. [less ▲]

Lot of soil survey focused on agricultural soils. For practical reasons, those soils have a low stone content. So, most of the soil water content sensors are placed on low stone content soils and the calibration equations are developed for them. Yet some researches take an interest in forest soils that are often much different from the previous ones. The differences lie in their stone content and their slope. Lots of studies have proved the importance of making soil specific calibration of the soil water content sensor. As our lab use regularly the 10HS sensors (Decagon Devices, United States) in forested soil, we decided to evaluate the importance of the stone content in the soil moisture measurement. The soil used for this experimentation comes from Gembloux (50◦33’54.9”N, 4◦42’11.3”E). It is silt that has been sieved at 2 mm to remove the gravel. The stones used to form the samples come from an experimental site located in the Belgian Ardennes (50◦1’52.6”N, 4◦53’22.5”E). They are mainly composed of schist with some quartz and sandstone elements. Initially, only five samples were constructed with three replications each. The size and the proportion of stones were the variables. Stones were classified in two groups, the first contains gravels whose size is less than 1,5 cm and a the second contains gravels whose size is comprised between 2 and 3 cm. The proportions of stone selected for the experiment are 0, 20 and 40%. In order to generate validation data, two more samples were constructed with intermediate proportion of stone content (30%). The samples were built in PVC container which dimensions are slightly bigger than the sensor volume of influence (1.1-1.3l). The soil samples were saturated and then dried on a thermal chamber set at about 32◦C. During at least 14 days, the samples soil water content was determined by the sensor measurement with the Procheck read-out system (Decagon Devices, United State) and by weighting the samples thrice a day. The evolution of the soil sample height was monitored as well. As first result, the stone content is a parameter that seems to influence soil water content. The stone size is no important. Because soil moisture deserves to be measured accurately in every soil and to confirm the first results the experiment is going on with more samples, different stone proportions, other sensor positioning and a natural air drying.

Some scholarly works on legal mobilization have highlighted the diffusion of litigious policies to address social problems in Europe, considering that a rights’ revolution was underway. While many of these studies have examined the diffusion of litigious policy at European level or in the United Kingdom, I suggest paying attention to Belgium and Sweden, two countries that have been under-examined by the socio-legal literature. Focusing on the implementation of anti- discrimination policy and norms, this paper explores the litigious activity of national equality agencies in the domestic labor court. The analysis of organizations’ litigious policy in Continental Europe invites to integrate another variable to the analysis of the structure of legal opportunities: the relationship between the State and interests groups. I suggest here that labor unions shape the access to labor courts by equality agencies in each national setting. This contribution aims to highlight equality agencies’ structure and agency within different labor contexts, current anti- discrimination policies and legal culture. It relies on open-ended interviews conducted with lawyers from equality agencies and labor unions in Belgium and Sweden. More broadly, this contribution examines the processes of policy implementation of European directive within member states. [less ▲]

In the literature, the political impact of metaphors has often been taken for granted from metaphor analysis in political discourse. However, a more global understanding of what this political impact could consist of, is still lacking from the current research agenda. To be able to account for how metaphors, through discourses, actively shape the political reality, it is important to look at the relationships between metaphorical discourses and their environment. Based on the idea that metaphors do not only reflect the perceived reality, but also function as cues through which citizens come to understand complex political processes (Bougher 2012), the aim of this study is precisely to look at how specific metaphors might impact on the citizens’ framing of Belgian federalism. To measure the impact of metaphors on the citizens’ political representations and attitudes, we conducted a first experiment among 493 citizens based on an article (including a text and an image) published in the newspaper Le Soir (13-14 July 2013) in which Belgian federalism was deliberately compared to a Tetris game (AUTHORS, submitted). The participants were distributed into four experimental conditions according to the type of input they had been exposed to (respectively no input, text and image, image only, text only), and were asked to perform three interrelated tasks (a free description task, a picture association task and a questionnaire measuring their attitude towards Belgian federalism). The productions of the participants in the description task have been analyzed using keyword analyses and content analyses. The results suggest that the participants who had been exposed to the experimental text tend to differently frame their perception of Belgian federalism (among other things, by highlighting the notion of transfer of competences from the federal state to the sub-national entities). Whereas these results suggest that reading the text might have an impact on the representations of the citizens, they do not allow us to pinpoint the specific role played by the Tetris metaphor itself on these different representations. To further determine to what extent the observed influence of the text on the citizens’ representations can be attributed to the Tetris metaphor, we developed a follow-up experiment for which we produced two versions of the experimental text, namely a version in which the Tetris metaphor remained explicit and a version in which it had been left out. We conducted the experiment among 600 citizens distributed into 3 experimental conditions (respectively no input, original text, original text without explicit reference to the Tetris metaphor). They were asked to achieve the same three tasks as in the original experiment. The results are currently being analyzed and will be the main subject of our contribution. This experimental design should allow us (i) to observe the specific influence of the Tetris metaphor on the integration of textual information and (ii) to assess to what extent it shapes the citizens’ representations of Belgian federalism.

Face à une situation de manque de terre et de pression démographique sans aucune amélioration des techniques de production, le choix des cultures à pratiquer permettant de rentabiliser la petite surface agricole disponible devient donc crucial pour les producteurs de Matongo en particulier et du Burundi en général. C'est dans ce contexte que le fruit de la passion est intégré dans les systèmes de production de certains ménages de Matongo dans le but d'améliorer leurs conditions de vie grâce à un supplément de revenu. Vu l'état actuel de la vulnérabilité de l'agriculture et de l'économie dans cette commune, il s'avère important de connaître les contraintes rencontrées par les adoptants du fruit de la passion en tenant compte de l'environnement dans lequel se pratique sa culture.

Difficulties in everyday life activities are core features of persons diagnosed with schizophrenia, and in particular for those activities requiring multitasking capacities. Multitasking refers to activities (e.g. preparing a meal) where the person has to: (a) carry out and alternate between different tasks that vary in terms of priority, difficulty and duration; (b) define the tasks’ targets; (c) and face unexpected problems during the realization of these tasks. Moreover, schizophrenia is characterized by a great heterogeneity in regard to their everyday life difficulties and cognitive functioning. 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 (i.e. the Computerized Meeting Preparation Task, CMPT). The aim of this study was to examine the multitasking abilities in persons diagnosed with schizophrenia and in particular the existence of subgroups of patients in regard to their performances on cognitive measures and on the CMPT. Sixty-two patients diagnosed with schizophrenia and 39 paired healthy controls completed the CMPT and a cognitive battery. The results reveal that the CMPT possesses good sensitivity and suggest three underlying constructs of multitasking (Memory, Planning and Intent), which were found to be underpinned by several cognitive functions and multitasking aspects. Moreover, cluster analyses revealed subgroups of patients differing in terms of their cognitive and CMPT performances. Taken together, these results show the need for a cognitive model of multitasking abilities in persons diagnosed with schiozphrenia. Taken together, this cognitive model and the CMPT, could be a good basis for cognitive interventions of multitasking abilities in schizophrenia. Finally, the results underline the heterogeneity of schizophrenia. [less ▲]

Monitoring tropical forest carbon stocks changes has been a rising topic in the recent years as a result of REDD+ mechanisms negotiations. Such monitoring will be mandatory for each country willing to benefit from these financial incentives in the future. Aerial and satellite remote sensing technologies offer cost advantages in implementing large scale forest inventories. Despite the recent progress made in the use of airborne LiDAR for C stocks estimation, no widely operational and cost effective method has yet been delivered for central Africa forest monitoring. Within the Maï Ndombe region of DRC, the EO4REDD project develops a method combining satellite, aerial and ground measurements. This combination is done in three steps: [1] mapping and quantifying forest cover changes using an object-based semi-automatic change detection (deforestation and forest degradation) methodology based on very high resolution satellite imagery (RapidEye), [2] developing an allometric linear model for above ground biomass measurements based on dendrometric parameters (tree crown areas and heights) extracted from airborne stereoscopic image pairs and calibrated using ground measurements of individual trees on a data set of 18 one hectare plots and [3] relating these two products to assess carbon stocks changes at a regional scale. Given the high accuracies obtained in [1] (> 80% for deforestation and 77% for forest degradation) and the suitable, but still to be improved with a larger calibrating sample, model (R2 of 0.7) obtained in [2], EO4REDD products can be seen as a valid and replicable option for carbon stocks monitoring in tropical forests. Further improvements are planned to strengthen the cost effectiveness value/REDD+ suitability in the 2nd phase of EO4REDD. This 2nd phase will include [A] specific model developments per forest type; [B] measurements of afforestation, reforestation and natural regeneration processes and [C] study of Sentinel data series potential use.

Plus que toute autre industrie, les carrières entretiennent un lien étroit avec les écosystèmes. L’exploitation d’une carrière crée des conditions abiotiques propices au développement d’une mosaïque d’habitats comme les falaises et arènes rocheuses, les plans d’eau temporaires ou les pelouses pionnières, favorables à certaines espèces protégées en Europe comme le hibou grand-duc et le crapaud calamite. Nombre d’entre eux sont d’intérêt communautaire et sont devenus rares dans le Nord de l’Europe. Ces habitats temporaires s’installent souvent spontanément pendant l’exploitation d’une carrière mais une action conservatoire peut s’avérer nécessaire pour leur conservation sur le long terme. En fin de vie de la carrière une restauration écologique adéquate pourra favoriser l’installation de milieux plus permanents d’intérêt. Afin de promouvoir le développement de cette biodiversité, une planification réfléchie des plans d’exploitation et de réhabilitation est nécessaire. La fédération des industries extractives belge FEDIEX s’est engagée en 2012 avec la Région wallonne dans une charte sectorielle « carrières et biodiversité », définissant un plan d’action basé sur trois axes principaux : (1) la sensibilisation des membres ; (2) la diffusion de recommandations pratiques pour intégrer la protection et la gestion de la biodiversité dans les plans l’exploitation ; (3) la formation du personnel des carrières. Dans ce cadre, l’unité Biodiversité et paysage de la Faculté de Gembloux Agro-Bio Tech (Université de Liège) collabore depuis 2012 avec la FEDIEX. Notre présentation portera sur les réalisations de cette collaboration ; notamment les formations « Carrières et Biodiversité » organisées à l’attention du secteur carrier, les résultats des actions concrètes mise en place en carrière, les documents de vulgarisation réalisés afin de donner aux gestionnaires les clés pour gérer et restaurer différents habitats et espèces protégées et notre collaboration à la rédaction d’un projet LIFE Biodiversity «LIFE in quarries » qui a été présenté à l’union européenne.

The increasing number of crane accidents recorded over the last years might be understood as a need for progress on crane modeling. The induced risk of self-excited vibrations has already been investigated through numerous experiments. This work presents a simple numerical model of a crane in a turbulent wind field, in order to support the available experimental approaches. First, the problem is defined with the necessary assumptions of the model. Second, the equation of motion is developed and wind characteristics are detailed. This equation presents several specificities requiring dedicated resolution methods. In a first analysis, the crane model is simplified in order to approach the behavior of the parametric pendulum and enable a general comparison of both responses. Indeed, the parametric pendulum is a well-known problem that is already widely described in the literature. In a second step, the response of the crane is studied under a realistic stochastic wind load with the full model. [less ▲]

The use of Geographic Information Systems within the field of archaeology has been demonstrated through numerous scientific studies in the past. However, such systems do not usually encompass all the characteristics of the archaeological data. Since 2009, the Geomatics Unit of the University of Liège works on the development of a robust, flexible and dynamic Archaeological Information System. The interdisciplinary research group focuses on the development of a conceptual data model based on the general characteristics of archaeological data namely its spatio-temporal, heterogeneous, multimodal and imperfect character. The following paper exposes latest output and especially the integration of archaeological data ambiguity [less ▲]

No Indo-iranian formula was coordinating gods with demons, but another one, welle attested, was linking mortal men with gods. Initially, it was saying the solidarity between both groups, who were meeting on the sacrificial ground. Its use in Rigvedic and Avestan texts shows divergent evolutions. In India, men and gods go away from each other. In Iran, the original coordination, whose negative meaning is appearing, is inserted ina an always wider demonic list, which is included in a sentence using another inherited formula, whose theme was the crossing of enmities. During the evolution process of this formula, men go with the ancient *daiva- to demonisation. [less ▲]
