The main objective of the present paper is a description of two effective numerical 2D models to be used as strategic tools in the process of flood risks assessment and mitigation. The first one is a model for hydrodynamics simplified according to the diffusive assumption while the second one is a complete model based on the shallow water equations. Each of them is solved with an efficient numerical technique (including implicit time integration schemes and GMRES linear solvers) maximizing the convergence rate towards a steady state. A practical case study, for which a high resolution Digital Elevation Model exists, will be presented. The study shows the consequences on structures of a new construction in the floodplain in terms of inundation and erosion. [less ▲]

Experimental and comparative data from subalpine ponds with and without tiger salamanders (Ambystoma tigrinum nebulosum) suggest that this species is a keystone predator on benthic and planktonic prey communities. At our study site in central Colorado, the population size of salamanders has fluctuated cyclically over the past 20 years from fewer than 100 to over 5000 individuals. Here we present long-term benthic data that reveal taxon- and habitat-specific correlations with fluctuations in salamander populations. In temporary habitats, benthic biomass changed little during fluctuations in salamander abundance. In permanent ponds, we observed order-of-magnitude changes in benthic biomass that were negatively correlated with salamander abundance. Among the large-bodied and potentially most vulnerable taxa (odonates, caddisflies, beetles, water bugs), several species exhibited negatively coupled cycles, but others fluctuated little or out of phase with changes in salamander abundance. The absence of major shifts in benthic community composition in permanent ponds is probably a result of conflicting predation pressures exerted by different year classes of salamanders. Data on ontogenetic shifts in salamander diet help explain why cyclic fluctuations in the abundance of this predator had only minor impacts on benthic community composition despite having major effects on invertebrate biomass.

Delineation of protection zones is performed by the use of stochastic simulations integrating all available data. In practice, due to the few available measurements of the main parameters, it can be very useful to integrate other data to reduce the uncertainty of the results. Most of the solute spreading is governed by the hydraulic conductivity (K) spatial variability at different scales. A stochastic approach adding measured piezometric heads and electrical resistivity data is presented. Results are discussed on a synthetic and on a practical case. Delineating the ‘Capture zone Probability Distribution’ (CaPD) for a given time, it is shown how the uncertainty can be reduced. The methodology can be used in real applications when little or no information is available about the hydraulic properties, through the conditioning on other data sets. [less ▲]

This paper presents the essentials of an original geometrically and materially non-linear 3-D tapered beam finite element. The theoretical bases of the element are described, with particular attention paid to the choice of an appropriate displacement field and to the corresponding non-linear axial strains. Specific numerical problems met in the development of the finite element are examined, concerning mainly shear and membrane locking and the handling of rigid body motions. Worked examples on isolated members are presented for various types of analyses: elastic linear, elastic critical and geometrically and materially non-linear analyses. Good accuracy with reference to numerical results is shown, as well as good convergence properties. It is also demonstrated – analytically and numerically – that the use of prismatic beam finite elements for the analysis of tapered beams (segmentation technique) may lead to significant discrepancies when the behaviour is influenced by torsional aspects.

The fatigue behaviour of the welded beam-to-column connections of steel moment resisting frame in seismic area must be evaluated. The cohesive zone model is an efficient solution to study such connections by finite elements. It respects the energetic conservation and avoids numerical issues. A three-dimensional cohesive zone model element has been implemented in the home made finite element code Lagamine [1]. It is coupled with the fatigue continuum damage model of Lemaître and Chaboche [2]. The cohesive parameters are identified by the inverse method applied on a three points bending test modelling.

We explore large-scale nucleotide compositional fluctuations along the human genome through the optics of the wavelet transform mi- croscope. Analysis of the TA and GC skews reveals the existence of strand asymmetries associated to transcription and/or replication The investigation of 14854 intron-containing genes shows that both skews display a characteristic step-like profile exhibiting sharp tran- sitions between transcribed (finite bias) and non-transcribed (zero bias) regions. As we observe for 7 out of 9 origins of replica- tion experimentally identified so far, the (AT+GC) skew exhibits rather sharp upward jumps, with a linear decreasing profile in be- tween two successive jumps. We describe a multi-scale method- ology that allows us to predict 1012 replication origins in the 22 human autosomal chromosomes. We present a model of replica- tion with well-positioned replication origins and random termina- tion sites that accounts for the observed characteristic serrated skew profiles. We emphasize these putative replication initiation zones as regions where the chromatin fiber is likely to be more open so that DNA be easily accessible. In the crowded environment of the cell nucleus, these intrinsic decondensed structural defects actually predisposes the fiber to spontaneously form rosette-like structures that provide an attractive description of genome organization into replication foci that are observed in interphase mammalian nuclei.

The roseate tern (Sterna dougalli) is an oceanic seabird species showing mainly a tropical distribution, with a relatively fragile status worldwide. It was still recently considered as a "near-threatened" (IUCN red list) due to the strong decline in population trends over the last decades. For instance, the annual breeding population found on Aride Island, western Indian Ocean, has fluctuated between a high of 4,000 in the 1970's to a low of 60-1200 pairs from 2000 onwards. As a result, an intensive monitoring program was conducted on Aride between 1998 and 2006 in order to understand how environmental factors may affects this breeding population. This included the estimation of annual productivity (no of chicks fledged per pair), demographic parameters such as survival rate and recruitment (age-specific breeding probabilities), and their affecting co-factors (e.g. food availability, tick parasitism,...). We suggest that these three parameters (productivity, survival, recruitment) constitute the necessary basis to model the life-cycle of this population, and, ultimately, to provide local managers with conservations measures.

The total concentrations of trace elements in soils results from natural and anthropic factors. Knowledge of natural distribution (e.g. bio-geochemical background) helps assessing the impacts of human activities in terms of contaminations. But the processes generated by the modifications of the soil environment may also affect the form of a trace element, that is its distribution through various pools. We investigated the chemical speciation of some metallic trace elements (Cu, Zn, Cr, Ni, Pb, Co, Cd) in soils from various land-use environment: “natural” soils under forest, “typical” cultivated soils, kitchen-garden soils, soils developped on geogenic anomalies and on contaminated areas. The analysis protocol aims at identifying different pools from their reaction to various extraction phases, ordered by increasing intensity in a single sequence. The different fractions are so-called soluble, linked to carbonates, to organic matter, to manganese oxides, to weakly cristallized Fe-Al oxides, to well-cristallized oxides, and residual. The “available” and total fractions have also been measured. The results stress the fact that the comparisons are difficult from one situation to another because each one represents a particular case of human activity without a common logic. The relationships with the classical pedological parameters are therefore difficult to generalize. However some relationships between elements have been found inside the various types of land use, which could be usefull in the risk assesment of transfers from soils to plants. [less ▲]

Multiple cameras and collaboration between them make possible the integration of information available from multiple views and reduce the uncertainty due to occlusions. This paper presents a novel method for integrating and tracking multi-view observations using bidirectional belief propagation. The method is based on a fully connected graphical model where target states at different views are represented as different but correlated random variables, and image observations at a given view are only associated with the target states at the same view. The tracking processes at different views collaborate with each other by exchanging information using a message passing scheme, which largely avoids propagating wrong information. An efficient sequential belief propagation algorithm is adopted to perform the collaboration and to infer the multi-view target states. We demonstrate the effectiveness of our method on video-surveillance sequences. [less ▲]

La construction d’un outil de gestion implique tout à la fois des connaissances, des anticipations, des choix sur les pratiques qu’elles visent à gérer. Dans le cas de la gestion des risques liés à l’usage des pesticides en Belgique, un « outil scientifique » (sous la forme d’un modèle et de ses indicateurs) est mobilisé et transformé afin de participer à une politique publique de diminution des risques. Les experts et modélisateurs d’un institut de recherche publique ont proposé - avec l’aide de chercheurs en sciences humaines - d’ouvrir à la discussion au sein d’un panel de citoyens la pertinence de la construction et de l’usage de leur modèle. Par cette situation expérimentale, plusieurs intérêts peuvent être poursuivis : évaluer la capacité de citoyens à apprendre et à s’approprier une thématique complexe et technique et à faire des propositions visant à « améliorer », voire à « dépasser » le fonctionnement dudit modèle ; mais aussi et surtout à étudier les conditions par lesquelles les experts eux-mêmes peuvent apprendre des remarques et suggestions de citoyens concernant leur pratique. C’est de ce double enjeu qu’est né le projet PEPAM. Cette présente communication vise à rendre compte de ses principaux enseignements lorsqu’ils touchent la question de la construction participative et démocratique d’outils scientifiques et de gestion dans le domaine environnemental.

Les résistances simples ou conjointes à la fluméquine et à l’enrofloxacine sont significativement plus rares chez les oiseaux de compagnie que chez ceux de production et semblent être dues à une sélection directe après traitement. Chez les oiseaux de production la fréquence des souches résistantes n’est influencée ni par l’âge, ni par la possibilité ou non de traiter les animaux (industrielle vs « bio-label »). Ces observations peuvent s’expliquer par le portage de souches résistantes dès la naissance des poussins; souches acquises au départ du cheptel reproducteur, ce dernier jouant un rôle disséminateur majeur lié à l’aspect typiquement pyramidal de la production avicole (faible nombre de parentaux qui produisent un grand nombre de volailles de production).

The role of corticosterone on the hippocampal structure and function is well documented in male rats. More recently research has shown that chronically stressed female rats with elevated corticosterone levels, exhibit significant dendritic alterations in the hippocampus and, paradoxically, enhanced learning and memory performance. Similar changes have been shown with first reproductive experience (primiparity) compared to further reproductive experience (multiparity). We have shown that at the time of weaning, primiparous rats exhibit altered hippocampal morphology (Pawluski and Galea, 2006), decreased hippocampal cell survival (Pawluski and Galea 2006), and improved reference memory performance (Pawluski et al, 2006) compared to multiparous and virgin female rats. Therefore, given the similarities to what has been shown in the chronically stressed virgin female rat, it seems plausible that corticosterone may play an active role in mediating the alterations seen in primiparous rats. The present study aimed to investigate whether there are differences in the level of free circulating corticosterone during late pregnancy and the postpartum period with reproductive experience. Total corticosterone and corticosteroid-binding capacity were assayed from serum in five groups of rats; multiparous, primiparous, pregnant-only, pup-exposed virgins, and nulliparous rats on 6 days (2 days during gestation: days 14 and 19, and 4 days during lactation; days 1, 5, 14, and 21, where applicable). Results show that total corticosterone level on postpartum day 1 was significantly elevated compared to all other days. In addition, primiparous and multiparous rats have significantly lower corticosteroid-binding capacity throughout lactation. This suggests that primiparous and multiparous rats have more free-circulating corticosterone during lactation. Further research is needed to determine the mechanism underlying the changes in hippocampal structure and function with primiparity. [less ▲]

It first reports on 4 full-scale tests performed at RWTH Aachen, on stiffened panels with strong closed stiffeners. As expected, failure in the subpanels has been governing. A devoted FEA shell model is then described and validated towards these results and other experimental sources. Parametric stud-ies led with the numerical tool help pointing out several aspects where the Eurocode 3 Part 1.5 recommenda-tions on stiffened panels in bending and shear may be improved. [less ▲]

This contribution presents the results of an experimental investigation carried out on the shaking table of the National Laboratory of Civil Engineering of Lisbon (LNEC), in order to validate the efficiency of some constructive proposals aiming at improving the structural behaviour of non engineered masonry housing subjected to low to moderate seismic action, with rather low costs compared to traditional North-European practice. Two specimens have been tested. These specimens were two full-scale small houses with two levels. The first one was built as a traditional Belgian house, while the second included some anti-seismic technical details. The main conclusions are that both specimens were still standing at the maximum earthquake level foreseen for Belgium, but that the improved model was much less damaged regarding crack openings in the walls. Therefore the economic consequences and repair costs would be much lower with these improvements. However the maximum ground acceleration that can be sustained by the structures seems to be very little influenced by the constructional detailing. [less ▲]

All farmers receiving direct payments are subject to compulsory cross-compliance which includes standards related to the maintenance and protection of permanent pastures. Questionnaire techniques and spatio-temporal analyses demonstrated that the ratio of permanent pasture area to agricultural land provides a simple tool for monitoring and controlling the protection of permanent pastures at the regional to Member State level. Huge variations in the ratio across Europe were related to the importance of permanent pastures, the interpretation of definitions, sources of information used, differences in calculation, and the presence of protective and/or sensitive zones. Precautionary or complementary measures are in place in most Member States in order to prevent decreases in the ratio. The implementation of GAEC standards related to permanent pastures overlaps with the standard management requirements, national legislation and current agri-environmental programmes. The study advocates the establishment of a comprehensive geo-information platform consisting of a topologically correct inventory of all permanent pasture parcels in a 1:1 geo-referenced relation between IACS and LPIS; ancillary spatially explicit data such as orthophotos, remote sensing images and other thematic geo-databases; and, geodatabases with parcel information compiled for other monitoring purposes such as those within the framework of the Nitrates Directive or 2nd pillar support.

The ALADDIN concept is an integrated Antarctic-based L-band experiment whose purpose is to demonstrate nulling interferometry and to prepare the DARWIN mission. Because of their privileged location, the relatively modest collectors (1 m) and baseline (up to 40 m) are sufficient to achieve a sensitivity (in terms of detectable zodi levels) which is about twice better than that of a nulling instrument on a large interferometer (such as GENIE at the VLTI), and to reach the 20-zodi threshold value identified to carry out the DARWIN precursor science. These numbers are based on a preliminary design study by Alcatel Alenia Space and were obtained using the same simulation software as the one employed for GENIE. The integrated design enables top-level optimization and full access to the light collectors for the duration of the experiment, while reducing the complexity of the nulling breadboard. [less ▲]

Les marges sud et nord du Sahara sont soumises à des processus de dégradation anciens attestés par de nombreux travaux de terrain. Ils coïncident avec l'occurrence d'une sécheresse sévère sur les 3 sites d'étude, débutée dans les années 1970 en Algérie (piémont sud de l'Atlas Saharien), au Maroc (bassin de l'oued Dadès) et en Mauritanie (lac d'Aleg, Brakna). Les suivis diachroniques par télédétection satellitaire (Landsat et SPOT) et aérienne (1954 à 2002) et des observations récentes, montrent la pérennité voire l'extension de certaines zones de dégradation localisées à proximité des agglomérations et points d'eau, malgré le retour des précipitations. Le rythme et les modalités de développement des dynamiques en œuvre, qui prennent la forme d'une dégradation qualitative et quantitative des couverts végétaux steppiques et de savane ainsi qu'une revivification des dunes d'Aleg, attestent du rôle prépondérant de certains activités humaines dans les processus de dégradation de ces milieux, en corrélation avec la crise climatique dont on peut se demander si elle n'est pas devenue un facteur secondaire. Sans ignorer les enjeux socio-économiques de développement, notre démarche vise à comprendre les logiques d'action des dynamiques complexes parfois abusivement désignées sous le terme simplificateur de «désertification».

Most studies that incorporate subsurface heterogeneity in groundwater flow and transport models only analyze and simulate the spatial variability of hydraulic conductivity. Heterogeneity of the other flow and transport parameters is usually neglected. This approach is often justified, but there are however cases in which disregarding the heterogeneity of the other flow and transport parameters can be questionable. In low permeability media, for instance, diffusion is often the dominant transport mechanism. It therefore seems logical to incorporate the spatial variability of the diffusion parameters in the transport model. This study therefore analyzes and simulates the spatial variability of the effective diffusion coefficient and the diffusion accessible porosity with geostatistical techniques and incorporates their heterogeneity in the transport model of a low permeability formation. The calculated output radionuclide fluxes of this model are compared with the fluxes calculated with a homogeneous model and a model with a heterogeneous hydraulic conductivity distribution. This analysis shows that the heterogeneity of the diffusion parameters has a much larger effect on the calculated output radionuclide fluxes than the heterogeneity of hydraulic conductivity.

Isomaltooligosaccharides (IMOs) are non-digestible oligosaccharides, considered as prebiotics and therefore aim to selectively feed probiotics indigenous to the human colon. Recent data obtained in human subjects, support the involvement of dietary oligosaccharides in physiological processes in the different intestinal cell type and also outside the gastrointestinal tract (e.g. hormone production, lipid and carbohydrate metabolism). IMOs consists of glucose monomers linked by at least one α-1-6, or in a lower proportion α -1-3 (nigerose family) or α -1-2 (kojibiose family) glucosidic linkages. In our case they are produced enzymatically from corn starch. It results in a very complex mixture with molecules characterized at the same time by their DP value (from 2 to ~20), linkages types (α-1-2, 3 or 6) and the proportion and position of each type of linkage (only α -1-6 or combined types). The challenge of this study was to find a qualitative and quantitative method to characterize the syrups. In a subsequent study, every unidentified peak could be determined by NMR or Mass spectrometry. Three different chromatographic methods have been tested and compared over their selectivity, sensibility, robustness, applicability and their quantitative power. The HPLC-RID (Refractive Index Detector) used with a Prevail Carbohydrate column (Alltech), adapted for carbohydrates with a certain value of DP, appear to be poorly selective due to the obligation of working in isocratic conditions. The HPLC-ELSD (Evaporating Light Scattering Detector) used with the same column gave a very good separation upon the DP as the Prevail accepts a wide range of solvant changing and even a separation of the different DP 2 molecules. The sensibility was also improved due to the stability of the baseline. The quantitative analysis is a bit more awkward due to the relatively limited linear portion of the calibration curve. High-performance Anion Exchange Chromatography coupled with Pulsed Amperometric Detection (HPAEC-PAD) appeared to deserve a special mention, since it provides selective separation and sensitive detection. In fact, this technique is the only chromatographic one to separate with effectiveness homologue molecules having a difference only in their DP (up to high DPs) or linkage types. This is due to the separation mode based on the difference in ionic force of the sugars in alkaline conditions (mainly due to the DP and the structure of the molecule). However, during the detection, the electrochemical behavior of carbohydrates can be affected by molecular weight as well as by structural differences giving rise to different response factors; as a consequence, HPAEC-PAD is not generally considered as suitable for quantitative studies of complex mixtures of oligosaccharides. In this work a methodological approach is presented in order to get a quantitative response through a rigorous methodology for our IMOs. It also opens the way to the theoretical determination of the response factor for the homologue molecules in relation with their structure and DP. [less ▲]
