Lateral mobility of Ardenne rivers has been studied at different scales using three complementary methods. We firstly compared the layout of channels on topographic maps (since the 18th century) and aerial pictures. Given that these documents have different scales and projection systems, they were transformed into a common referencing system. This method allowed us to study the lateral shifting of channels, however, as the mobility of Ardenne rivers is relatively low, the errors of geometric rectifications are often more important than lateral displacements. Therefore, to visualize these deformations, georeferenced documents were overlaid with a regular grid of points. We represented the imprecision vector based on x and y residual components for each point. These vectors show the direction of the deformation and its amplitude. Large quantities of iron slag are present in the sediments of Ardenne rivers. These waste products come from hundreds of ironworks built close to rivers since the 14th century. Analyses of slag concentrations in alluvial deposits allowed us to delimitate the sectors of floodplains eroded by rivers during the last centuries. In these sectors, slag elements are present at the contact with the gravel sheet. Finally, we analysed the topography of floodplains from a DEM-LIDAR. This digital elevation model has been established by the Walloon Region for the cartography of flood risk in floodplains. It presents a Z mean error of only 15 cm and a X-Y resolution of 1 m. In order to reveal paleochannels and topographic alluvial units, we subtracted a surface, corresponding to the longitudinal water surface slope, extracted from the DEM. By using this method, we are able to obtain the relative height of any point of the floodplain with regard to the water surface, projected perpendicularly to the layout, on this point. This procedure reveals paleochannels even if they are almost infilled and allows us to delimitate, for several kilometres, alluvial units, which have been formed at different periods. [less ▲]

Steroid receptors such as estrogen receptors alpha and beta and androgen receptors are transcription factors involved in the transcriptional regulation of a large number of target genes. Steroid-dependent expression in the brain controls a large array of biological processes including spatial cognition, copulatory behavior and neuroprotection. The discovery of a competition, or squelching, between two different nuclear receptors introduced the notion that common cofactors might be involved in the modulation of transcriptional activity of nuclear receptors. These cofactors, which are now known as coactivators, are involved in chromatin remodeling and stabilization of the general transcription machinery. Since the characterization of the steroid receptor coactivator 1 or SRC-1, more than 100 different cofactors have been identified. Although an increasingly large amount of information has been collected about the in vitro function of these coregulatory proteins, relatively little is known regarding their physiological role in vivo, particularly in the brain. Our laboratory and others have demonstrated the importance of SRC-1 in the differentiation and activation of steroid-dependent sexual behaviors and the related neural genes. In Japanese quail, the inhibition of SRC-1 expression by intracerebroventricular antisense injections blocked the activating effects of exogenous testosterone on male sexual behaviors and the steroid-dependent vasotocine expression and increase of the median preoptic area volume defined by Nissl staining as well as by aromatase immunoreactivity. These data therefore strongly suggested that SRC-1 is required to modulate estrogen receptor dependent gene-expression. It is however interesting to note that steroid receptors and SRC-1 are not always colocalized. For example, both glial cells and neurons in the hippocampus express estrogen receptor alpha but SRC-1 is rarely observed in glia. It is therefore possible that estrogen receptor alpha in glial cell require another coactivator or set of coactivators to induce estrogen-dependent gene transcription. It has been suggested very recently that SRC-1 is associated with neuronal differentiation of neural stem cell derived from the ganglionic eminence of mouse embryos. These stem cells differentiating into glial cell (GFAP-positive) did not express SRC-1. The presence of a specific coactivator could therefore determine a specific cell phenotype (neuronal vs glial). Another coactivator, the coactivator-associated arginine methyl transferase 1 or CARM-1 seems to be important to keep progenitor cells in a dividing state. The inhibition of CARM-1 expression leads to neuronal differentiation. Neurogenesis can therefore offers an excellent model to define the spatio-temporal role of different coactivators. It is indeed possible to study a subset of coactivators associated to various stages phenotype determination (proliferation vs. differentiation). The study of neurogenesis in the dentate gyrus of the hippocampus in female adult rats shows that around 40 % of proliferative cells express SRC-1 or CARM-1. Interestingly, 70% of proliferative cells express SRC-1 but only a very few cells (<5%) express CARM-1. We are currently investigating the temporal pattern of expression of these two coactivators during the neurogenesis in the hilus and dentate gyrus. The expression of the coactivators CARM-1 and SRC-1 is analyzed in proliferating and differentiating cells. We expect that proliferating and differentiating cells will differentially express the two coactivators. It seems that the presence of a precise subset of coactivators could help defining the phenotype of the cell by modulating a specific downstream pathway after steroid receptor activation. The very large number of coactivators and their association into preformed complexes potentially allows the determination of hundreds of different phenotypes. The study of the expression of the coactivator and their function in vivo is required to fully understand steroid action and specificity in the brain. [less ▲]

This paper is devoted to nonlinear numerical modeling of reinforced concrete columns subjected to fire. In this work we analyze reinforced concrete columns loaded by eccentric compressive forces and exposed to a standard fire. That the columns have an extremely important role in building, the verification of fire resistance in fire conditions is crucial. The analysis is divided into two steps. In the first step we make the thermal study of column. It follows the temperatures depending of time that we use in the second stage for the mechanical study, where we get the variation of different parameters such as bending moment, stresses, displacements and tangent modulus.

In accordance with the water Framework Directive (WFD, European Parliament & The Council of the European Union, 2000) defining the overall ecological status of rivers, many hundred sites were analysed in the Walloon network. Within each sample, macroalgae data were gathered at species/or at genus level and the main water quality parameters were collected several times per year from 2005 to 2009. <br /><br />Seventeen species and genera cited in the French and English lists of macrophyte methods used to assess the ecological quality of rivers were considered. Within these sites, the ratio of the macroalgae among the contributory species was examined and the impact of these on the final scores of the River Macrophytes Nutrient index (United Kingdom, Wilby et al.,2006) and the biological macrophytic index in rivers (France, Haury et al., 2006) was analysed.At the same time, a ranking of these macroalgae along a trophy gradient has been established thanks to a principal component analysis of the physico-chemical parameters and a weighting of the species presence in a given waterbody by its abundance.The relationships between macroalgae scores and those found in France and in United Kingdom were studied using the Spearman rank correlation coefficient. <br /><br />Literature: <br /><br />European Parliament & The Council of the European Union, 2000.

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 ▲]

Experimental investigations have demonstrated the importance of platelets and their activation for bone regeneration around oral implants. This study aimed to numerically demonstrate the key role of activated platelets which is controlled by implant surface characteristics. The cellular activities involved in the process of peri-implant endosseous healing can be represented by migration, proliferation, differentiation, removal, extracellular matrix synthesis and degradation, and growth factor production/release and decay. These activities are described by a system of highly coupled non-linear partial differential equations of taxis–diffusion–reaction type. Moreover, cell–biomaterial interactions were treated by including surface-specific model parameters. A well-designed in vivo model that looked at healing around oral implants with different surface properties was selected from literature to validate the results. Numerical simulations agreed well with the experimentally observed healing response and demonstrated that platelet-related model parameters, which were dependent on implant surface characteristics, modulate the pattern of healing.

Experiments were conducted in a 0.25 m diameter bubble column to investigate the effect of animal cell culture medium composition on oxygen transfer rate. Air is used as the dispersed phase. The gas superficial velocity is varied between 0.4 and 2 cm/s (aeration rate ranging between 0.05 and 0.25 vvm) and the bubble column is thus operated in the homogenous regime. Aqueous solutions the composition (electrolyte, protein concentrations) of which mimics a mammalian cell culture medium) are used as the continuous phase. In particular, the effect on oxygen transfer rate of additive such as PVP, Pluronic F-68 which are usually used to protect cells against local hydrodynamic stresses induced by bubble coalescence and bursting is addressed. For each composition, the mass transfer coefficient is measured by the "gas in – gas out" method using a fast response dissolved oxygen probe. Its increase with gas velocity is measured. The liquid viscosity and surface tension are experimentally determined as a function of culture medium composition. Bubble size distribution is measured at different scales using three experimental techniques: gas disengagement technique, two dual optical probes and photography, which lead to results in good qualitative agreement one with each other. The integrated analysis of these data allows to decouple the effects of the different additive on coefficient kL and on the interfacial area, a. [less ▲]

This study was aimed at investigating whether the recognition of familiar faces is more likely to be associated with an experience of Remembering than the recognition of familiar names. Using the Remember/Know paradigm the proportions of episodic memories recalled following the recognition of famous faces and names (Conditions) were assessed. Presented faces and names were previously judged by an independent group of participants as eliciting an equivalent level of familiarity. Nevertheless significant differences between the two conditions appeared in hit and false alarm rates. However, present results showed no significant difference in the recollection of personal memories (Remember responses conditionalized on the hits), following familiar faces compared with familiar names recognition. This finding contrasts with recent accounts assuming that faces are more prone to yield episodic memories than other cues to person identity. These results and their implications for current Interactive Activation and Competition person recognition models are discussed. [less ▲]

The north European plain appears to have been abandoned during the Last Glacial Maximum. However, beginning with the Dryas I, evidence for population movement and re-colonisation of Belgium and Germany can be observed with the establishment of Magdalenian populations. Cultural traits are identical to those observed in Northern France. Later, regional traditions develop during the Bölling (Hamburgian, Creswellian). Finally, a very early Mesolithic appears during the Alleröd and Dryas III. [less ▲]

The concept of the ‘active school’ emerged a decade ago as the role with increasing recognition of the role of schools in the promotion of physical activity. The purpose of this paper is to present the findings of a study which, drawing on Cale’s ‘Active School’ model, aimed to compare the nature and extent of physical activity promotion in secondary schools in three European regions. In so doing, it aimed to establish whether there were cultural differences in the strategies and approaches adopted by schools. [less ▲]

Fear-related stimuli (e.g. spiders) seem to be prioritized during visual selection when they are actively searched for. This is especially true if the observers fear them. It remains unclear whether such stimuli capture attention automatically when they are task-irrelevant. To answer that question, we used the additional singleton paradigm (Theeuwes, 1992) in which participants searched for a shape singleton (a circle among diamonds) while a fear-related stimulus (a spider) or a fear-unrelated stimulus (a butterfly) was also present in the display. To assess whether fear affects the extent of a possible bottom-up capture, we compared performance of participants that scored high or low on the Fear of Spiders Questionnaire (Szymanski & O'Donohue, 1995). Results showed that both types of task-irrelevant animals captured covert attention. Importantly, both types of animals produced larger interference in high-fear than in low-fear participants. This study suggests that fear as an individual characteristic influences bottom-up capture. [less ▲]

DINEOF (Data Interpolating Empirical Orthogonal Functions) is a method to reconstruct missing data in geophysical data sets, such as gaps originated by the presence of clouds in infrared satellite sensors. Based on Empirical Orthogonal Functions (EOFs), DINEOF uses an iterative procedure to calculate the missing values. DINEOF has been compared to Optimal Interpolation, showing that more accurate results are achieved, with up to 30 times less computational time (tests made with sea surface temperature of the Adriatic Sea, and validated with in situ data). Another advantage of this technology is that there is no need for a priori knowledge of the reconstructed data set statistics (such as covariance or correlation length). The technique can be applied to a broad range of data (physical, biological, chemical), and to a variety of platforms (satellite data, in situ data...). Given the nature of the EOFs, it is not necessary that data sets are regularly distributed in time. Irregularly distributed data sets, however, may lead to discontinuities in the temporal EOFs calculated from them, and these discontinuities can affect in turn the quality of the DINEOF reconstruction. In satellite data, some images can present a large amount of cloud cover, and only a few pixels with valid data. EOF projection to such images can also lead to discontinuities in the temporal modes, as there might be an over-fitting to the scarce information present in those images. After briefly describe DINEOF and its applications, we present a study aiming to reduce these discontinuities by including a time constraint to the covariance matrix used in the EOF decomposition. The approach is tested with sea surface temperature data of the Black Sea, and the results are compared to independent data. [less ▲]

In the Ardenne massif, floodplains have recorded fluctuations in the production of sediment and several periods of increased sediment deposition have been identified. Before the first deforestations rivers developed multiple channels in alluvial forests. Floodplains were not well-developed and probably very humid, which explains the presence of peat layers within the alluvial sequences. In the Amblève catchment, the first increased sedimentary deposition of the Holocene occurred during the Bronze Age (3200 BP), in relation to deforestation and the first crop cultures in the area. An organic deposition has occurred around 2700 BP and could correspond with a period of climatic degradation. Several peat layers have also been dated to around 1000 BP and probably indicate very low anthropogenic pressure. From the 11th Century onwards, there was an increase in sedimentation and a greater concentration of charcoal is present in the alluvial deposits. In many catchments there is an important increase in the sedimentation at the end of the 14th century, which can be related to the development of many iron factories. Analyses of slag concentration produced in these former factories allow us to reconstruct the evolution of the floodplain topography since the inception of the iron industries, in relation to the periods of activity. Total sedimentation in the smaller valleys since the initiation of iron industries amounts 0.5 to 1.0 m, which is in most cases about 50% of the total sediment present in the floodplains and corresponds to a mean sedimentation rate ranging between 10 and 20 cm/century. Such values are explained by various former agricultural practices and forest clearings associated with the huge demand for charcoal by the iron industry. About 20 ha of forest were cleared for the yearly consumption of a refining forge or a blast furnace and more than three hundred iron factories existed in the Ardenne Massif between the 14th and the 19th century.

The operational management of rivers during low flows periods needs a best knowledge of the hydrological processes involved. Therefore a study aiming at the regionalization of low flows discharges in the Walloon Region has been started. Its first objective is to characterise the lowest flows throught existing monitoring network. Homogeneous regions will be defined on the basis of the results obtained. For each one, regression equations will be build in order to permit the computation of low flow discharge at any point of an ungauged river. [less ▲]
