Among natural factors driving the soil content in metallic trace elements (MTE), the geochemical background is often deemed as a sound base for the detection of contaminations. Numerous studies have shown the difficulties to take into account the multi-dimensionnality of the spatial variability of most soil properties. As far as a detailed soil map is available for Belgium, the relevance of its information was investigated at various spatial scales in the Walloon Region (Southern Belgium), from the plot to the entire region, to evaluate the feasibility of a multi-scale mapping of geochemical background. The soil properties of 410 plots from the regional forest soil monitoring and the relationships with informations related to the physical environment (lithology, soil types...) were investigated through multivariate statistical analysis. Some processes of integration of point measurements and qualitative information were also explored. At the regional scale, some long-range spatial structures could be identified. These result mainly from the geological structure of the Walloon region, where the lithological zonation is rather clearly marked. The soil map (texture and nature of stone charge) appears relevant at that scale too but does need a generalization process and fails however to differenciate the intra-type soil spatial variability.

Refractive solar concentrators suffer from important chromatic aberration. To enhance solar cell performance and increase the concentrating ratio, we propose an hybrid (diffractive/refractive) lens which allows a more uniform flux density and an achromatized (in the sense of achromatic doublet) illumination of the cell. To solve the problem of high diffraction efficiency, we turn to multilayer diffractive lenses to have broadband high diffraction efficiency optimized on solar spectrum. Rigorous coupled wave analysis simulations were performed in order to check the validity of scalar theory, they led to a new order of magnitude for the ratio period/wavelength which has been found to be around 100 in place of 10.

Crown rot disease of bananas is widespread in producing countries and is considered as the most important post-harvest disease of exported bananas. Variations of susceptibility to the disease have been noted between bananas but the origins still unknown. The biological responses of the fruit, including physiological change and disease susceptibility are controlled and regulated by gene expression. One way to understanding the reactions involved in variation of banana susceptibility to the disease in relation to their physiological state, is to study the expression of genes involved in these processes. To this purpose, crown sample previously inoculated with C. musae and showing 2 levels of susceptibility (very high and very low) were collected to be compared. Crown sample of each susceptibility level was collected at two different maturity stages: at harvest and 13 days after harvest (3 days after ripening). Collected crowns were immediately freeze-dried, an original method to conserve gene expression. cDNA-AFLP was applied on these 4 cell populations in order to highlight the differential transcription of genes whose function is "a priori" unknown. The cDNA-AFLP result was confirmed using quantitative real-time reverse transcription PCR. Various defence-related genes were identified and will be presented. [less ▲]

Background: Results of nonmyeloablative HCT in pts with HLA-mismatched donors have been disappointing due to high incidence of graft rejection and severe acute GVHD. Recent studies have suggested that infusion of mesenchymal stem cells (MSC) the day of HCT might promote engraftment and prevent acute GVHD after myeloablative allogeneic HCT. However, some studies suggested that MSC co-infusion might abrogate graft-versus-host alloreactivity and graft-versus-tumor effects. This prompted us to investigate whether MSC infusion a few hours before HCT could allow nonmyeloablative HCT from HLA-mismatched donors to be performed safely (i.e. with a 100-day incidence of nonrelapse mortality < 35%). Methods: 20 patients with hematological malignancies were given MSC (1-2 x 10E6 cells/kg) from third party donors a few hours before PBSC from HLA-mismatched unrelated donors, after conditioning with 2 Gy TBI and fl udarabine 90 mg/m. Postgrafting immunosuppression included tacrolimus (day -3 to +180; tapered by day +365) and mycophenolate mofetil (tid days 0 to +42). HLA-compatibility was assessed at the HLA-A, -B, -C, -DRBI and DQBI loci: 13 pairs were mismatched for at least one HLA class I antigen (including 4 pairs who were also mismatched for 1 HLA-class II antigens (n=3) or 1 HLA-class I allele (n=1)), 1 pair was mismatched for 2 HLA class II alleles, while 6 pairs were mismatched for a single HLA class I (n=3) or HLA class II (n=3) alleles. Results: Median follow-up for surviving patients was 288 (range, 76-571) days. One patient with secondary AML had primary graft rejection, while the remaining 19 patients had sustained engraftment. Median donor T-cell chimerism levels on days 28, 100, 180 and 365 after HCT were 90%, 98%, 96%, and 98%, respectively. Grade II, III and IV acute GVHD were seen in 5, 2 and 1 patients, respectively, while 7 experienced NIH moderate/severe chronic GVHD. Three of 7 patients with measurable disease at transplantation achieved complete remission on days 41, 104 and 353 after HCT. Two patients died of nonrelapse causes on days 74 and 114 after HCT, while 3 died of disease progression. Projected 1-yr overall and progressionfree survivals were 77% and 61%, respectively. Conclusions: HLA-mismatched nonmyeloablative HCT with MSC co-infusion appeared to be safe, with MSC co-infusion possibly mitigating graft-versus-host alloreactivity without abrogating graft-versus-tumor effects. Survival is encouraging. [less ▲]

A top-down integration scheme for silicon vertical nanowire (NW) tunnel field-effect transistors (TFETs) with a 35nm nanowire dimension and using state-of-the-art metal gate and high-k gate dielectric is demonstrated. Using the short-gate concept [1], the ambipolar behavior of the TFET is successfully suppressed. The measured TFET performance is not yet beyond that of the MOSFET, most likely due to the use of silicon that has a large bandgap and the use of ion implantation for the formation of the tunnel junction which results in a low junction abruptness. To boost the device performance, a low thermal budget processing could be used on etched nanowires in a substrate with epitaxial grown junction, in order to increase the abruptness of the tunnel junction.

Contact employees play a critical role in creating favorable customer perceptions. We aim to understand to which extent contact employee emotional intelligence relates to customer perceptions of rapport, and their satisfaction and behavioral intentions. We developed a causal model and tested it with PLS. We found that customer perceptions of contact employee emotional intelligence influence their perceptions of rapport. In turn, rapport influences cognitive and emotional satisfaction. Both types of satisfaction lead to behavioral intentions. In order to improve customer perceptions of rapport, managers could focus on contact employees’ emotional intelligence when hiring and training them. [less ▲]

The bonobo, Pan paniscus, an endemic primate of the DRC, forms with the chimpanzee, Pan troglodytes, the pair of species closest to humans. Classified as “Endangered” by the IUCN, it’s seriously threatened by the degradation of the forests. Only the creation of protected areas large enough and properly managed can improve its status but requires a good knowledge of the eco-ethology of the local populations. Our project will focus on studying a bonobo population recently discovered in the region of the Lake Tumba, in the west of the DRC. It is characterized by densities never encountered elsewhere, and a preliminary study has revealed significant differences in habitat and food resources in comparison to these of eastern populations. We will contribute to a recently established WWF conservation program by gathering eco-ethological data on bonobos, data that will allow identifying areas to protect, their boundaries and management measures to implement. To do this, we will study the diet of bonobos via direct and indirect observations of their behavior. We will also study the party size and its composition and identify underlying environmental factors. We will assess the bonobos’ home range size and pattern of displacement, which we will correlate with the abundance of food resources to determine whether there is a pattern of occupation of time and space specific to this population.

The importance of different sources of phenotypic variation, namely adaptation, phenotypic plasticity, environmental maternal effects, ploidy level and genetic drift, were estimated in several life history traits among populations of an invasive plant species within its invasion range. Several common garden experiments were set out, two of which in a reciprocal transplants experiment. The populations considered in this study were located in Belgium, in France and in the native range of the model species. Senecio inaequidens DC. (Asteraceae) is native to Africa. It was introduced in Europe via wool trade in the late 19th century. In the native range, the species occurs at two co-existing cytotypes: diploid and tetraploid. Only tetraploid individuals are reported in Europe. The particular and well-documented invasion history of S. inaequidens makes it an excellent plant model for evolutionary studies. Several life history traits were measured, related to germination, growth and sexual reproduction. The sources of phenotypic variation in those traits were analysed with respect to climatic variation along altitudinal gradients in the invaded areas. The influence of the ploidy level and the range (native vs introduced) on those traits was also analysed. Results showed that diploid and tetraploid populations differed, mainly in winter survival capacity. Along altitudinal gradients, clinal phenotypic differentiations with a genetic basis were observed among populations. However, environmental maternal effects were found to significantly influence phenotypic variation in areas with harsh climatic conditions. Monty A., Mahy G. 2009.

Depuis une dizaine d’années, les eaux côtières corses sont envahies les méduses et en particulier par les Pelagia noctiluca qui présentent une nuisance pour les eaux de baignade, les installations aquacoles et hydrauliques côtières, interfèrent avec la pêche, colmatent les filets et entrent en compétition avec les poissons pour la nourriture. Leurs apparitions dans les eaux côtières sont généralement fortuites, discontinues dans les temps et dans l’espace et souvent sous forme d’essaims. Dans le cadre du programme MEDUSES, subsidié par l’Agence de l’Eau RMC, des observations visuelles directes et des comptages de Pelagia effectués depuis 2003 à partir du quai du port de STARESO montrent une augmentation graduelle de leur abondance de 2004 à 2005 suivie par une augmentation dramatique en 2006 puis une diminution significative les étés 2007 et 2008. La prolifération de Pelagia en 2006 succède à des biomasses particulièrement élevées de mésozooplancton en 2005. On peut émettre l’hypothèse que l’abondance exceptionnelle des proies planctoniques est une des causes de la prolifération. Les Pelagia vivent en essaims dont deux types sont observés en Baie de Calvi: des essaims passifs et des essaims actifs. Les essaims passifs observés dans le port de STARESO contiennent des individus généralement dégradés (perte des tentacules, du manubrium,..), voire moribonds mais qui restent urticants. Parfois réduits à la seule ombrelle, ils se déplacent peu et s’accumulent en grand nombre (parfois plus de 200 par m2), bord à bord, en essaims passifs limités aux trois premiers mètres de la surface. Ces essaims subissent une prédation active par de nombreux poissons sparidés (bogues, sars,...). Ils disparaissent en quelques heures du fait de cette prédation ou par sédimentation massive des animaux morts. Par contre, dans les eaux plus au large, nos mesures in situ de la distribution spatiale de Pelagia noctiluca montrent que durant les pics de 2006, de nombreux organismes sont présents à distance de la côte où ils forment des essaims actifs de 200 m de long et 50 m de large situés entre 10 à 60 m. Dans ces essaims actifs, on observe de 5 à 10 individus par m3. Ceux-ci sont équidistants et nagent activement avec les tentacules étendus, capturant la nourriture. Dans certains cas, des individus moribonds partiellement détruits ou à la fin de leur cycle biologique échappent des essaims actifs et dérivent passivement à la surface, sous l’action du vent et des mouvements de l’eau, vers les zones côtières. Entre ces deux types extrêmes d’essaims, divers cas intermédiaires existent. [less ▲]

A method is presented to create an ensemble of perturbations that satisfies linear dynamical constraints. A cost function is formulated defining the probability of each perturbation. It is shown that the perturbations created with this approach take the land-sea mask into account in a similar way as variational analysis techniques. The impact of the land-sea mask is illustrated with an idealized configuration of a barrier island. Perturbations with a spatially variable correlation length can be also created by this approach. The method is applied to a realistic configuration of the West Florida Shelf to create perturbations of the M2 tidal parameters for elevation and depth-averaged currents. The perturbations are weakly constrained to satisfy the linear shallow-water equations. Despite that the constraint is derived from an idealized assumption, it is shown that this approach is applicable to a non-linear and baroclinic model. The amplitude of spurious transient motions created by constrained perturbations of initial and boundary conditions is significantly lower compared to perturbing the variables independently or to using only the momentum equation to compute the velocity perturbations from the elevation [less ▲]

Time use surveys often are carried out to identify, classify and quantify social behaviour of people by focusing on the activities that people perform. Time use data, in the transportation field often referred to as activity-based data, can be used to study a variety of sociological, economic, and technological phenomena. Studying behaviour, social networks and transport patterns are a few of the topics that can be analysed based on these time use data. This first introductory paper discusses some emerging issues in the collection of travel-related data such as automatic spatial information recording using cell phones and GPS, and survey design experiences. On the one hand new technology offers the opportunity to record at a relative low cost a wide variety of the data, while on the other hand new problems occur. One of such problems for instance is the problems of ‘cold starts’ faced with GPS devices, clouding the first minutes of recording after each restart of the device after it was turned off completely. Notwithstanding, applications of new technologies offer the opportunity for performing detailed space-time analyses in different fields ranging from epidemiology to transportation science. Some of these applications are highlighted in this session. Next to the advantages and potential risks of new technologies, this introductory paper also discusses the combination of different modes to analyze space-time behaviour. In particular, this study investigates potential mixed mode design effects, observed in a large activity-based travel survey, using a PDA application on the one hand, and traditional paper and pencil diaries on the other hand. The mixed-mode effects are analysed using heteroscedastic linear regression models, taking into account not only mode-effects, but also potential fatigue-effects. The results show that in this mixed-mode survey no attrition effects are present, and that the survey mode (PDA versus paper and pencil) has no direct impact on the quantities investigated (number of out-of-home activities reported and number of trips).

Abstract : Here, we aim to develop the conditions of possibility of a collective learning process for the forest ecosystem governance. We argue that stakeholders’ discussion and public debate should be intrinsically interconnected with the expertise of the soil-plant cycle. As Chris Argyris underlines, “[i]t is possible to develop knowledge, both valid and which can be “put into action” in everyday life” and which “provides an opportunity to test it in everyday life”. Primary forest is the most biologically diverse type of vegetation system and is characterized by a balance between biomass production and soil evolution. Soil, as the nutrient source, plays a crucial role in the forest productivity. Currently, only 21% of the world forests are indigenous. Human activities, through the “production paradox”, disrupt this homeostasis between the nutrient source and the vegetal production. The mobility of nutrients in the soil-plant system has to be taken into account for sustainable forest governance. Then, the knowledge of the relationship between soil and plant is a “proper way to compose, decompose, or recompose problem sets” and could also be a proper possibility of “controversy” that allows us to elaborate a collective and critical learning process which “entails an appreciation of complexity and an effort to integrate problems into a more comprehensive whole”. Finally, our governance hypothesis focuses on a critical environmental ethics which integrates both the common sense moral feelings involving stakeholders and the knowledge of causal relationship in a forest ecosystem (i.e. soil-plant cycle). This critical environmental ethics will be established on a “critical knowledge” as Jean Ladrière underlines it into his work on science and rationality. [less ▲]

Spatially-discontinuous Galerkin methods constitute a generalization of weak formulations, which allow for discontinuities of the problem unknowns in its domain interior. This is particularly appealing for problems involving high-order derivatives, since discontinuous Galerkin (DG) methods can also be seen as a means of enforcing higher-order continuity requirements. Recently, DG formulations of linear and non-linear Kirchhoff-Love shell theories have been proposed. This new one-field formulations take advantage of the weak enforcement in such a way that the displacements are the only discrete unknowns, while the C1 continuity is enforced weakly. The resulting one field formulation is a simple and efficient method to model thin structures and can be applied to various computational methods. [less ▲]

Ce texte traite des politiques de lutte contre le travail des enfants au Burkina Faso dans une perspective historique, en cherchant à comprendre comment le travail des enfants a été construit comme « problème » dans les politiques publiques . Le but est d’explorer l’origine des politiques contemporaines de lutte contre le travail des enfants dans ce pays, en remontant aux politiques coloniales françaises en Haute-Volta, actuel Burkina Faso. Nous nous proposons de répondre à la question suivante : Face à l’émergence et au renforcement des politiques publiques de lutte contre le travail des enfants au Burkina Faso, assiste-t-on à un ratissage du modèle de l’enfant du lignage qui percevait l’enfant comme une « richesse » et une force de travail complémentaire? Ceci nous permettra d’analyser l’évolution et la portée de l’intervention des pouvoirs publics pour imposer une nouvelle vision de l’enfant (l’enfant de la Nation). Enfin, nous interrogerons la place réservée à l’ « enfant travailleur » dans ces politiques. [less ▲]

Cette communication porte sur l’analyse des transformations identitaires exprimées dans les discours des enseignants en formation initiale. Cette analyse nous a permis de dégager des axes de transformation qui pourront servir d’outils dans le cadre de séances de réflexivité collective et individuelle avec les futurs enseignants en leur offrant des éléments d’intelligibilité pour les aider à se situer par rapport à leur propre parcours de développement et par rapport aux différentes attentes institutionnelles à leur égard.
