La présente communication porte sur la bande dessinée expérimentale contemporaine et se focalise plus particulièrement sur "Travelling Square District" (2010) du jeune dessinateur belge Greg Shaw. Objet très singulier, cet album se présente comme une expérimentation systématique autour du cadre mobile, dans un art fondé sur des successions d'images fixes. En cela, cette œuvre peut être considérée comme relevant d'une para-histoire du cinéma. [less ▲]

The prediction of cereal-crop yield is considered as a priority in most crop research programmes due to the relevance of food grain to feeding the world population. Today, a large number of agrometeorological models for crop yield assessment are available with various levels of complexity and empiricism. But, currently the development of wheat yield forecasting models in conventional operational systems do not reflect the loss of active green leaf area and its relation to biotic and abiotic processes implicated in the crop production situation. In 2009 a large field campaign in the Grand-Duchy of Luxembourg was realized to assess the validity of leaf-green-area approach to further improve yield prediction. Hemispherical photography were taken on winter wheat fields during the crop cycle, preferentially from inflorescence emergence to maturity. The variable of interest, the Green Area Index (GAI), was retrieved after image analyses using the CAN-EYE software. The regression-based models calculated with metrics derived from the decreasing curves of GAI showed that final yield could be better estimated with satisfactory precision: range of the coefficient of determination (R²) varies from 0.73 to 0.86 and RMSE (root mean square error) is varying between 0.43 and 0.56 t/ha. The validation of such approach at the scale of an agricultural zone or region is currently under progress, by using green area index temporal profiles and information on the phenology of winter wheat. Such simple models may be considered as a first step towards yield estimation that may be completed by other agrometeorological models in order to provide a better integrated yield assessment.

The aim of this article is to define the perception of the images of Liège town centre and to find the factors which explain the differences between these images. It is based on an extensive survey carried out in 1978, in 7 different places, with 1 552 people, and continues research work done in 1974. The steps : the integration or rejection of the town centre of places situated in a marginal position in relation to the centre, the delimiting of this centre, the laying down of the advantages and drawbacks of the centre and the choice of a central point.

Summary - Weather-Radar Rainfall Measurement and Simulated Surface Wetness Duration for Septoria Leaf Blotch Risk Assessment. The persistence of free moisture on leaves, mainly as a result of precipitation in the form of rainfall or dew, plays a major role during the process of plant infection by most fungal pathogens. Acquiring rainfall and leaf moisture information is needed for accurate and reliable disease prediction and management. The objective of this research is to contribute to improve forecasting Septoria leaf blotch and other fungal pathogens on winter wheat in Belgium and Luxembourg. In the first part of this work, the potential of weather-radar rainfall estimates for plant disease forecasting is discussed. At first step, we focused on assessing the accuracy and limitations of radar-derived precipitation estimates, compared with rain-gauge data. In a second step, the Septoria leaf blotch prediction model PROCULTURE was used to assess the impact on the simulated infection rate of using, as input data, rainfall estimated by radar instead of rain gauge measurements. When comparing infection events simulated by PROCULTURE using radar-derived estimates and reference rain gauge measurements, the probability of detection (POD) of infection events was high (0.83 on average), and the false alarm ratio (FAR) of infection events was not negligible (0.24 on average). FAR decreased to 0 and POD increased (0.85 on average) for most stations, when the model outputs for both datasets were compared against visual observations of Septoria leaf blotch symptoms. Analysis of 148 infection events observed over three years at four locations showed no significant difference in the number of simulated infection events using either radar assessments or gauge measurements. This suggests that, for a given location, radar estimates are just as reliable for predicting infection events as rain gauges. As radar is able to estimate rainfall occurrence over a continuous space, unlike weather station networks that do observations at only a limited number of points, it has the great advantage of being able to predict the risk of infection at each point within an area of interest with an accuracy equivalent to rain gauge observations. This gives radar an important advantage that could significantly improve existing warning systems. In the second part, a physical model based on the energy balance, known as the Surface Wetness Energy Balance (SWEB), was applied for the simulation of Surface Wetness Duration (SWD) on winter wheat canopy. The model, developed in the United States on grapes canopies, was adapted for the winter wheat cultivars and was applied for use with agrometeorological data easily available from standard weather stations and weather-radar rainfall estimates. The SWEB model simulates surface wetness duration for both dew and rain events. The model was validated with data measured by sensors and with visual observations of SWD conducted in experimental plots during two cropping seasons in 2006 and 2007. The wetness was observed visually by assessing the presence or absence of surface water on leaves. Based on the results, the SWEB model appeared to underestimate surface wetness duration and especially for the dry-off events when compared statistically to visual observations. The error, on average, is generally less than 90 minutes. In order to establish a relationship between the surface wetness periods and Septoria leaf blotch development risk on the top three leaves, the SWEB model SWD outputs were compared with the number of hours of high probability of infection simulated by PROCULTURE as well as with visual plant diseases observations. A minimal surface wetness duration of favourable infection conditions for Septoria tritici was established. It is now required to develop an operational system that would integrate weather radar, surface wetness duration and foliar epidemic model. In this work, we have analyzed the advantages and limitations of the radar system as input to models and its ability for spatial interpolation of rainfall. We also tested the model for the determination of surface wetness periods required for Septoria Leaf Blotch Risk development. The proposed approach could be integrated in the existing system. Finally this approach shows once more the "happy marriage" between agrometeorology and plant disease management. [less ▲]

Des études antérieures ont montré que, en Wallonie, des limites lithologiques de certaines formations primaires peuvent apparaître sur des photos aériennes prises en période de sécheresse. La très haute résolution de certaines images satellitaires actuelles (0,61m en panchromatique et 2,44m en multispectral) permet également de distinguer la structure géologique sur des images saisies dans des conditions de sécheresse similaires. Ainsi, l’image Quickbird couvrant la région de Wellin et Beauraing (provinces de Luxembourg et Namur) et datant du 21 juillet 2006, soit après 51 jours d’absence de précipitations, montre de façon particulièrement visible la structure géologique dans les roches finement litées de l’Eifelien.

Le nationalisme, la xénophobie, le racisme et l’antisémitisme, l’opposition aux élites, la stigmatisation des étrangers, les discours anti-immigrés, mais aussi l’autoritarisme, l’idéologie ‘loi et ordre’ (Law and order), l’antiparlementarisme et l’anticommunisme, entre autres traits caractéristiques, représentent quelques-uns des qualificatifs les plus souvent cités dans la littérature consacrée au populisme et à l’extrême droite. En fonction des partis politiques concernés, des contextes institutionnels et des particularités nationales et géographiques, ces qualificatifs prendront une dimension centrale ou secondaire selon qu’il s’agira de caractériser un courant populiste ou un parti d’extrême droite. A l’appui d’une comparaison entre la France et les Etats-Unis, l’ouvrage vise à démontrer que l’ensemble de ces qualificatifs entretiennent tous à des degrés divers un rapport fondamental avec un ‘imaginaire du complot’, c’est-à-dire avec un monde de significations structuré et cohérent (normes, significations, images, symboles, valeurs et croyances) qui privilégie la théorie du complot pour expliquer la politique et l’histoire.
