Within the periurban areas of big cities, soils are often contaminated by heavy metals spread by human activity: atmospheric fallouts due to industry and traffic, recycling of urban wastes (directly or after water treatment), fertilizers and pesticides used in agriculture… This is, among others, verified in the surroundings of Kunming (Yunnan, PR China) and Lille (Nord-Pas de Calais, France), areas with high density of population and traditional metallurgical industries. These areas have also intensive agricultural activities characterized by important vegetable productions, and are generally known as the "green belts" of the cities. These cultures, with short vegetative period, need high biodisponibility of nutrients, biodisponibility which may also occur for other unwanted elements existing in the soil, such as heavy metals. For evident human health reasons the quality of the crops must be ensured and their heavy metal content kept as low as possible, at least under the values of relevant legal thresholds. Thus, vegetables are particularly sensitive to the presence of heavy metals in the soils where they are growing. It is therefore necessary to manage these soils in order to preserve public health or, more basically, the income of the farmers, as contaminated vegetables would not be marketable. Thus, for these large areas contaminated by diffuse pollution, bioremediation looks to be appropriate. But the kind of the bioremediation which will be applied has to be adapted to the severity of the soil pollution and to the intended land use. In this project, we have assessed the contents of Pb, Cd, Zn and Cu of soils and vegetables within the Chenggong county (near Kunming), and compared the results to the already known situation of the surroundings of two lead and zinc smelters located close to Lille. Then goals and ways of bioremediation have been discussed and the first steps of implementation experimented. [less ▲]

The objective of the present study was to compare transrectal ultrasonography and pregnancy associated glycoprotein (PAG) tests for determination of pregnancy in 72 Holstein-Friesian heifers imported from Holland to Croatia. All heifers came to Croatia with written confirmation of pregnancy. During caranteen we preformed rectal and ultrasound exploration of heifers and simultaneously collected blood samples from each heifer. PAG concentrations were determined by a RIA immunoassay using bovine PAG 67 KDa as a tracer and standard. In our study 68 heifers were confirmed to be pregnant by both methods and 4 cows were confirmed for abortion by PAG test and nonpregnant according to ultrasound checking. Transrectal ultrasonography is accurate test for pregnancy diagnosis in pregnant heifers but it is impossible to say only on basis of ultrasound examination if heifers conceived and aborted or they failed to conceive in the first place. PAG RIA test is not only highly accurate and reliable method to distinguish between pregnant and nonpregnant heifers on the market. It is also useful to determine whether heifers were pregnant and embryo died and was absorbed during the transfer or heifers failed to conceive. It is possible because level of PAG persists in circulation after abortion or embrional death. In doubtful cases it can be used as a proof of pregnancy existence in heifers later confirmed to be nonpregnant. [less ▲]

The electromagnetic interaction between Io and Jupiter's magnetic field leads to single or multiple UV spots in both jovian hemispheres. Variations of the multiplicity of the spots and the inter-spots distances have been observed and are linked to the position of Io in its plasma torus. These morphological changes have a timescale of a few hours. We have studied the footprint evolution with a time resolution of a few tens of seconds using the HST/STIS camera in the time-tag mode. This approach resulted in an evaluation of the impact of the rapid evolution of the jovian magnetic field lines when measuring the dimensions of the spots with a longer exposure time. More basically, evidence of strong brightness variations of the main spots (up to 40%) have been observed with a typical growth time of 1 minute. Finally, unexpected simultaneous fluctuations of both primary and secondary spots have also been found in the southern hemisphere. In conclusion, the characterisation of the variations mentioned herein provides clues for a complex and rapidly evolving energetic electrons precipitation mechanism. [less ▲]

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.

Solar absorption measurements using Fourier transform infrared (FTIR) spectrometry carry information about the atmospheric abundances of many constituents, including information about their vertical distributions in the troposphere and the stratosphere. Such observations have regularly been made since many years as a contribution to the NDSC (Network for the Detection of Stratospheric Change). They are the only ground-based remote sensing observations available nowadays that carry information about key atmospheric trace species in the free troposphere, among which the most important greenhouse gases. The European UFTIR project (Time series of Upper Free Troposphere observations from a European ground-based FTIR network, http://www.nilu.no/uftir) has focused on maximizing the information content of FTIR long-term monitoring data of some direct and indirect greenhouse gases (CH4, N2O, O3,HCFC-22, and CO and C2H6, respectively). The UFTIR network includes six NDSC stations in Western Europe, covering the polar to subtropical regions. At several stations of the network, the observations span more than a decade. Existing spectral time series have been reanalyzed according to a common optimized retrieval strategy, in order to derive distinct tropospheric and stratospheric abundances of the abovementioned target gases. A bootstrap resampling method has been implemented to evaluate trends of the tropospheric and total burdens of the target gases, including their uncertainties. In parallel, simulations of the target time series have been made with the Oslo CTM2 model: comparisons between the model results and the observations provide valuable information to improve the model, and in particular, to optimize emission estimates that are used as inputs to the model simulations, and to explain the observed trends. The final results of the project will be presented, and ways to proceed will be discussed. [less ▲]

Results of FEM simulations predicting the mechanical behavior at room temperature of test specimens of ultrafine-grained aluminum produced by ECAE are presented. The constitutive law is either based on a Hill model or on the Minty micro-macro model and coupled with an isotropic hardening law and/or kinematic hardening law. The yield locus shape, its size and its position during tension, compression and torsion tests have been studied. Initial texture measurements allow the identification of a constitutive law based on a set of representative crystals and crystal plasticity approach using a Full- Constraint Taylor model. Finite element simulations using the previous constitutive laws are compared with experimental investigations. The results show that applying an initial back stress identified by tensile and compression tests to the yield locus predicts the initial flow stress in torsion test. The Minty micro-macro model coupled with a Voce type hardening model gives a good agreement with experimental results for the prediction of the shape at different stages of deformation of a compressed test specimen. The simulation of tensile tests underline the need of inverse modeling as, due to the test specimen shape, the test is far from being homogeneous. The link between test specimen length and the necking appearance is studied. [less ▲]

In many plants, flowering is promoted by a long exposure to cold, a process known as ‘vernalisation’. In Arabidopsis, the vernalisation pathway was shown to promote flowering via the repression of the FLOWERING LOCUS C (FLC) gene, which encodes a repressor of flowering. As far as we know, the genetical control of flowering is conserved among Brassicaceae, and we reported elsewhere cloning of flowering times genes of the photoperiodic pathway in Sinapis alba, based on sequence similarity with Arabidopsis. However, little is known about vernalisation in Sinapis. We therefore undertook a physiological and molecular study of this process. Plants of Sinapis were grown in non inductive short days and vernalised at 7°C, at the seedling stage. Vernalisation was found to accelerate flowering and an increasing effect was observed for vernalisation treatments longer than 2 weeks. We cloned an FLC-like sequence (SaFLC) by screening a cDNA library, and used it as a probe to perform expression analyses. We observed that SaFLC was almost completely repressed after 1 week of vernalisation, but repression was stable only after 2 weeks, which is consistent with the fact that 2-week is the minimal duration of vernalisation that promotes flowering. Hence the molecular mechanisms of vernalisation seem to be conserved in Sinapis and Arabidopsis. [less ▲]

The space mission PEGASE, proposed to the CNES (Centre National d'Etudes Spatiales = French Space Agency) in the framework of its call for scientific proposals : "formation flying missions", is a 2-aperture interferometer, composed by 3 free flying satellites (2 siderostats and 1 beam combiner), allowing baselines from 50 to 500 m in both nulling and visibility modes. With an angular resolution of a few mas and a spectral resolution of several tens in the spectral range 2.5-5 microns, PEGASE has several goals:science : spectroscopy of hot jupiters (Pegasides) and brown dwarves, exploration of the inner part of protoplanetary diskstechnology : validation in real space conditions of formation flying, nulling and visibility interferometry concepts.PEGASE has been studied at a 0-level. In this paper, we summarize the scientific program and associated technological and mission trade-off coming from this 0-level study. We also discuss how PEGASE can be considered as a TPF/DARWIN pathfinder in an international roadmap towards more complex space interferometry missions such as DARWIN/TPF. [less ▲]

Même si elles peuvent contribuer de manière très spectaculaire à la maîtrise de la qualité microbiologique des aliments, les techniques de conservation elles-mêmes ne sont pourtant qu’un moyen de maîtrise parmi d’autres… Deux facteurs principaux sont tout simplement la qualité initiale –en particulier la qualité microbiologique- des aliments ou des ingrédients qui les constituent et l’hygiène observée au cours de leur production, de leur transformation et de leur distribution. De plus, un effet « obstacle » n’est reproductible que dans des conditions précises, par exemple pour ce qui concerne le nombre de microorganismes, la composition de l’aliment, les conditions d’ambiance, etc… Une technique de conservation doit donc être validée dans des conditions données (p.ex. par validation de la durée de vie microbiologique permettant d’estimer la D.L.C. d’un produit). Toute modification de ces conditions ne permet plus de garantir la maîtrise de la qualité microbiologique. Il convient par ailleurs d’évaluer l’effet d’une contamination accidentelle de la denrée par un microorganisme pathogène, au cours de sa production, de sa transformation ou de sa distribution (test de croissance après inoculation artificielle de la denrée, encore appelé « challenge testing »). L’établissement et le respect de critères microbiologiques, de bonnes pratiques de fabrication et de procédures d’assurance qualité sont des points clés de la maîtrise de la qualité et de la sécurité sanitaire des aliments. Des progrès significatifs sont en cours et sont encore attendus dans les prochaines années. [less ▲]

This study investigates the relative data value of different types of secondaryinformation to estimate the flow and transport parameters in low-permeability media. Data from four boreholes in two different clay formations are analyzed. Cross-validation is used to estimate the relevance of the different types of secondary data. The flow and transport parameters (hydraulic conductivity, diffusion coefficient and diffusion accessible porosity) are first estimated by kriging using primary information only and then estimated by co-kriging using primary information and one type of secondary information (grain size, gamma ray and resistivity). The kriging residuals, i.e. the difference between the estimated and the measuredvalues, of the different kriging and co-kriging variants are compared to evaluate the relevance of each type of secondary information. This analysis shows that in the different clays and the different boreholes, different types of secondary information result in the largest improvement of the estimates of the flow and transport parameters. It is not possible to determine the "best" type of secondary information for improving the estimation of the flow and transport parameters of low-permeability media. This probably depends on local factors such as the quality of the loggings and the amount of nearby primary and secondary data. [less ▲]

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.

Supplied by the Ganga–Brahmaputra fluvial system, the Bengal Fan provides an integrated record of the Himalayan basin history through time. The active channel-levee system of the middle fan documents the last glacial/interglacial cycle. Organic geochemistry studies have shown that the organic matter contained in the Bengal Fan sediments is mainly of terrestrial origin. We analysed terrestrial n-alkanes (C27–C33) from Bengal Fan sediments and modern Ganga–Brahmaputra sediments. Comparison of compound specific hydrogen and carbon isotopic ratios in these samples allow us to follow the evolution of paleoenvironmental conditions since the Last Glacial Maximum. Carbon molecular isotopic data on the odd-HMW n-alkanes show a shift of 4&, corresponding to an evolution in the Himalayan system from a C4-dominated vegetation at LGM to a C3- dominated vegetation during the Holocene. It is now well known that C4 plants are more adapted than C3 plants to low atmospheric CO2 concentrations and to relatively hot and dry climate. In the same time, molecular D/H isotopic ratios measured on the same samples show an increase of the deuterium content of about 20& during the Holocene, which is consistent with lower temperature at the end of the LGM in the Himalaya. As low temperature should favored C3 plants, the predominance of a C4 vegetation have to be linked with dryer conditions at the end of the LGM. Afterwards, the increase of the C3/C4 ratio in the Himalayan system is related to a concomitant increase of humidity and pCO2 during the Holocene. [less ▲]

YBa2Cu3O7-δ thick films have been deposited onto Ag substrates by the Electrophoretic Deposition (EPD) technique. Different microstructures and electrical behaviours were observed depending on the starting powder. Coatings prepared from commercial powder displayed significant porosity and the superconducting transition width was found to be magnetic-field dependent. Films produced from home-made coprecipitated powder are denser but contain some secondary phases. No dependence of the resistive transition as a function of magnetic field (H ≤ 20 Oe) was observed in that case. [less ▲]

Le béton est réputé durable. L’expérience de cette durabilité est toutefois fort limitée en termes d’échelle temporelle : nombreux sont les facteurs – internes et externes - qui peuvent amener une dégradation parfois très rapide du matériau. Fort heureusement, ces dégradations n’ont que très peu souvent d’effet irrémédiable sur le comportement structurel de l’ouvrage en béton. Les réparations permettent en général de prolonger la durée de vie des structures, en réhabilitant le comportement du matériau : l’adhérence du système de protection ou de réparation constitue dans ce cas une condition nécessaire mais pas toujours suffisante. Définir les conditions d’ « appétence » est la première étape du processus : quelles sont les conditions minimales à rencontrer pour que les matériaux « adhèrent », dans un environnement donné ? Ces conditions sont-elles suffisantes pour garantir la durabilité des réparations ? De plus, l’évaluation de l’adhérence pose problème en soi : traction, cisaillement, torsion sont autant de sollicitations censées représenter le comportement réel d’une interface : quel type d’essai employer ? Comment allier facilité et efficacité ? Laboratoire et chantier ? [less ▲]

Approximated genetic correlations between direct longevity and type traits were computed for a sire Holstein population. Data were based on results for type traits (77,965 records) and for direct longevity (74,289 records) from the INTERBULL routine run of November 2005. Most of type traits presented a high relationship with direct longevity (from 0.06 up to 0.29). The strongest positive correlation with longevity was for udder depth (0.29) and the strongest negative correlation was for chest depth (-0.21). According the different results, an animal with a good direct longevity seemed to be smaller and less heavy than an animal with a shorter longevity. [less ▲]

Les débats médiatiques sur la mondialisation s’articulent autour de deux thèses apparemment antagonistes. Pour les partisans du libéralisme économique et les représentants des milieux d’affaires, il s’agit de condamner l’interventionnisme et le dirigisme politique dans le libre-jeu de l’économie de marché. Les chefs de file syndicaux et dirigeants réformistes de l’« altermondialisme », entendent, quant à eux, défendre, bec et ongles, l’idée d’un personnel politique victime de la bourse et des pressions de divers lobbies industriels et financiers. Dans les deux cas pourtant, on procède à une dissociation artificielle et trompeuse de l’économique et du politique. Cette représentation dominante de la mondialisation est à l’origine d’une censure, celle qui, derrière le paravent de l’Etat « victime » ou « bourreau » des marchés, refuse la parole aux critiques dénonçant les liens organiques entre pouvoirs économique, politique et médiatique.

Cet article porte sur un corpus de photographies écrites et peintes et concerne les relations (contractuelles et contrastives) entre texte photographique, écriture manuelle et gestualité picturale. L’écriture dans l’image est étudiée comme : 1) stratégie d’authentification de l’objet-photo (autographie de l’objet photographique unique), 2) comme notation, 3) comme gestualité, 4) comme effet-texture de l’image. L’écriture entendue comme stratégie d’authentification du texte photographique permet de réfléchir sur la problématique de l’original, de la reproductibilité et du statut hybride de la photographie écrite, à mi-chemin entre autographie et allographie (« texte autographique à objet multiple »).

This paper addresses the design of algorithms for the collective optimization of a cost function defined over average quantities in the presence of limited communication. We argue that several meaningful collective optimization problems can be formulated in this way. As an application of the proposed approach, we propose a novel algorithm that achieves synchronization or balancing in phase models of coupled oscillators under mild connectedness assumptions on the (possibly time-varying and unidirectional) communication graphs.
