Lorsque les signaux embryonnaires de la gestation induisent une modification du côté maternel, une possibilité nouvelle s’ouvre aux chercheurs attentifs au développement de tests pour le diagnostic ou le suivi de la gestation. Dans ce chapitre, nous essayerons de passer en revue les différentes molécules dont le dosage ou la mise en évidence a fait l’objet de publications scientifiques en relation avec le diagnostic de la gestation. Dans la mesure du possible, nous envisagerons les différents marqueurs en suivant la chronologie de leur apparition au cours de la gestation, mais ce critère ne prendra pas un caractère absolu car souvent plusieurs molécules se recouvrent, ou encore leur apparition au niveau de placenta précède largement le moment où elles apparaissent dans le sang maternel en quantités mesurables. Nous essayerons également, de connecter chaque molécule avec l’application que son dosage permet dans la clinique vétérinaire. Pour terminer, nous ferons une description rétrospective de quelques cas cliniques bien documentés qui montrent l’importance de l’association du dosage de protéines associées à la gestation et de la progestérone pour arriver à une meilleure compréhension des échecs observés dans le déroulement de la gestation.

This paper provides information about the numerical simulation of the dynamic behaviour of linear structures including non linear dampers, for which the relation between the damping force and the velocity is described by a power law. A first part of the paper deals with single degree of freedom (SDOF) systems, with a particular emphasis on the resolution of the non linear equation allowing to compute the damping force corresponding to a given velocity. A second part deals with multi degree of freedom (MDOF) systems, and presents a special algorithm to study the behaviour of structures with a very small number of non linear components. [less ▲]

We use the results of numerical modeling, calibrated and verified againsthistorical data from 1960 to 1995 and the most recent data from the 2001 Knorr cruise,to investigate the redox budget of the Black Sea water column and the main processesgoverning this budget. The results can be summarized as follows: (1) Injection of Mediterranean water, through the Bosporus, into the Black Sea results in intrusions of oxygen in the suboxic and anoxic layers; (2) The intensity of ventilation of the CIL andthe export production of organic matter are the primary control on interannualvariations in the thickness of the suboxic zone; (3) The lateral influx of oxygen resultsin oxidation of sulfide inside the anoxic zone. Almost 70% of the total vertical flux of sulfide is oxidized by this oxygen, mainly through redox Mn(II) – Mn(III,IV) cycling;(4) Nitrate seams to be responsible for oxidation of dissolved Mn(II) in the suboxiczone and Mn(III,IV) hydroxides, the end-products of this oxidation, sink and oxidizeabout 25% of the total flux of sulfide; (5) The vertical flux of oxygen at the onset of sulfide may account for consumption of a small fraction (less than 1%) of the total fluxof sulfide; (6) The lateral flux of oxygen also appears to be the main reason for the presence of the suboxic layer.

The slenderness of plated structures together with a generalised use of high strength steel leads to a great importance of stability phenomena. The practical way to deal with such problems is to use rules proposed in design codes. A common alternative to design codes is the use of non linear finite element simulations. One of the most sensitive point in these simulations is the choice of the initial imperfections to be introduced in the model. The present paper discusses the effect of initial imperfections on the calculated collapse load. Several parameters are considered (shape, magnitude and direction). Results of numerical simulations are also compared with those of a design using Eurocode 3 or ECCS Recommendations. Two cases of plate geometry are studied (plate with one single stiffener and plate with multiple stiffeners). [less ▲]

A numerical approach for modeling the coupled hydro-mechanical fracture behavior is proposed. The movement of fluids through rock fractures and consequently the evolution of their hydraulic conductivity is an important subject in many petroleum related activities, mainly concerning the change of well productivity during the reservoir life. It is well known that the flow in the fractures is strongly controlled by the fracture apertures. Recent investigations on the distribution of the apertures in natural fractures suggest that the cubic law can, better than the Darcy law, predict the fluid flux through rough walled fractures as long as the appropriate average fracture aperture is used. A finite element code is developed to predict the influence that the stresses variation in the fracture has on the distributed hydraulic conductivity field. The proposed model combines the stochastic cubic law with a non-linear deformation function (hyperbolic) that is suggested to describe the stress-closure/opening curves of the joints and that allows to couple together the hydraulic and the mechanic fracture behavior. The relationships used and the validity of the present model are tested by means of the comparison between experimental data and numerical predictions (Bart 2000) in various bound-ary and loading conditions. Comparisons between the proposed new model and a no coupled one have also been performed. They show that the proposed coupled model allows for a more realistic description of the fracture behavior.

Classical beam elements are based on the assumption that the cross section of the element re-mains unchanged during the entire loading. However, this can be too simple for modeling the behavior of thin-walled steel profiles, where local and distortional buckling are likely to occur. In this perspective, a spe-cial element taking into account the deformation of the cross section is presented and some examples of com-putations of critical bifurcation loads are presented. [less ▲]

Problems in continuous casting of steel are numerous and have been leading producers to find ever more efficient solutions. Wa have developed a thermomechanical model of continuous casting, using a non-linear finite element code. Since a complete 3D discretization seemed impossible, the model has been based on a generalized plane strain state (2D1/2) and it includes at the same time thermal exchanges, mechanical behaviour of steel at very high temperature, the ferrostatic pressure and contact between the strand and the machine. This paper presents some results of two industrial applications. First results tend to prove the importance of some process factors (such as the mould taper) and local defects of the machine on the quality of cast products, according with observations. [less ▲]

Dam breaching is an important factor that should be included in an embankment break model. Indeed the assumption of instantaneous break is not suitable in case of earth dams, which fail gradually and thus induce a delayed peak outflow, significantly reinforcing the flood wave front. Unlike computations performed classically, WOLF software package deals with the different phenomena (erosion processes, reservoir emptying and downstream wave propagation) in a completely integrated way. This finite volume computer code has been completely developed by the authors at the University of Liege. Transient discontinuities are properly handled thanks to an original splitting of the convective terms. The paper briefly presents WOLF software, which includes a physically based hydrological model, an original 1D flood routing (appropriate for any natural river network) and a 2D shallow-water solver. The latest hydrodynamic model is coupled to a mass balance for bed load sediments. Solid discharges are evaluated with reliable transport capacity laws. Gravity induced solid discharges are taken into account by means of side slope stability analysis. This paper also exhibits how WOLF software package has been successfully applied to the completely coupled computation of a gradual dam breaching process, with a focus on downstream effects on wave propagation. WOLF proves its ability to achieve the integrated computation of solid transport, flows upstream, through the breach, in the scour hole and in the whole downstream valley. Major feedback effects on the upstream part of the reservoir are shown and they demonstrate the relevance of such an integrated approach. [less ▲]

Some authorities (DGPL) of the Walloon Region (Belgium) are involved in the realization of a complete regional coverage (16,844 km²) of natural colour ortho-photomap to be used at large scales (up to 1:4000). These are made of very high-resolution digital ortho-rectified aerial photos presented as raster files. Those rasters are grouped by corresponding administrative boundaries and distributed to the local authorities in order to be used for various land and urban planning purposes. One goal of the DGPL is to provide the local administrations with up to date image data, within the limits of some obvious financial constraints. Because significant changes in the landscape appear at different rates over the time and space, it was suggested to devise a methodology to find out these changes would require a rapid update of the imagery. In regard to this situation, a pilot project has been set up in the year 2000 aiming at detecting the location, the extent and the nature of landscape changes in contrasted areas - urban, suburban, rural - from adequately processed very high resolution (VHR) satellite images - typically Ikonos multi-spectral (4m) and panchromatic (1m) images. Hence, this project had to cope with various issues related to multi-source analysis, geometric and radiometric aspects of the processing VHR data, diachronic analysis, in order to provide the administration with the basic knowledge and the appropriate tools to carry out the proposed task. This communication presents the proposed operational methodology for change detection including all processing steps from the digital image processing (image fusion technique, ortho-rectification analysis, change detection schemes). Along the way it also introduces an assessment of the possible complementarities and convergence of VHR satellite imagery and aerial photography. [less ▲]

This paper presents an initiative, FORMADIS, aiming at producing a critical mass of quality courses and thus, contributing to the dissemination of good practices in ODL. A competitive call has been launched in 2001 and 2002 to select 23 projects to be closely coached and turned into on-line active courses. The teachers, by working on their own course with the support of instructional, technical and graphic specialists move from a traditional way of considering their course to a more open view of what it could be. Applying the principles of isomorphism and transfer, the teacher training program in pedagogy, partly on line and partly face to face, helps in the different stages of development of the course. As anticipated, this setting appears to be an effective way to provide continuing education to teachers. The produced courses illustrate the diversity of implemented strategies and the added-value due to ODL. Over 40 activities have been described and analysed, according to the “7 teaching/learning paradigms” model. [less ▲]

Major threats for the mountain environment and citizens which are connected to mining and processing of the uranium are due to the contamination of the hydrosphere by radio nuclides, and due to the stimulation of dangerous natural and technological processes (landslides, mudflows, destruction of the tailings and dumps) with unfavorable ecological consequences.

This paper presents the parallelization model used for the non-linear finite element software LAGAMINE. The proposed model is based on the use of a coarse grain approach for the parallelization of the assembly of the stiffness matrix. For the solver of the generated linear problem, we used a parallel direct solver of Gauss type. Finally, we present a discussion of the results of our approach on an example of depp drawing.

The finite element code LAGAMINE developed since 1982 has been adapted to numerous finite elements and constitutive laws. The present researches on micro-macro modelling increase the requirement of CPU time. The parallelization of software is often divided into two main approaches: the coarse grain approach and the fine grain approach. For Finite Element software, the coarse grain method is usually characterized by the use of the mesh partitioning. In the fine grain approach, there is no partition of the mesh. The parallel program is made by the parallelization of instructions issued of the nalysis of dependences between the instructions, and the loops. The efficiency of all these approaches depends on the organization of the memory and on the used exchange protocol (MPI, PVM, or OpenMP). Our approach is intermediate between these two main categories of parallelization. It is characterized by the parallelization of the assembly of the stiffness matrix using a coarse grain approach and the use of a parallel direct solver. Because of the architecture of the available parallel computers, which are shared memory, we decided to use OpenMP protocol. [less ▲]

The FUV instrument on IMAGE frequently observes localized ultraviolet emission at high latitudes, poleward of the general auroral oval. These localized emissions occur during northward IMF conditions and there are two different types of them. One type is especially distinct in the observations of Doppler shifted Lyman alpha emission from proton precipitation. This type occurs during high solar wind dynamic pressure. We interpret this emission as the optical signature of proton precipitation into the cusp after lobe reconnection at the magnetopause. The second type of localized emission is distinct in the wide-band (WIC) and oxygen (SI13) images, but is absent in the proton images. This emission occurs during positive IMF By, but very low solar wind density and dynamic pressure. We interpret this emission as the optical signature of electron acceleration in the upward part of a field aligned current circuit after reconnection. [less ▲]

The FUV instrument on the IMAGE (Imager for Magnetopause-to-Aurora Global Ex- ploration) satellite monitors the aurora in three different spectral regions. The Wide- band Imaging Camera (WIC) observes the molecular N2 LBH and the atomic NI emissions at 140-180 nm. The two channels of the Spectrographic Imager (SI) ob- serve the Doppler shifted Lyman- emission at 121.8 nm due to precipitating protons (SI12) and the electron auroral emission of OI at 135.6 nm (SI13). We calculate the Pedersen and Hall ionospheric conductances due to auroral particles based on FUV observations separately for the proton and electron precipitation. We first estimate the electron and proton energy fluxes from the FUV data, relying on energy degradation and auroral emission models. A two-stream model is used for the electron aurora while the proton aurora modeling is based on the direct Monte Carlo method, which gives a stochastic solution to the Boltzmann equations for the H+ - H beam. The electron energy is evaluated by combining observations from the three FUV instruments. For the proton energy, we use a statistical model based on in-situ particle measurements. Second, the particle energy and energy flux are used to estimate the ionization rates separately for protons and electrons, consistently with the energy degradation models. Finally, the electron and ion densities are estimated from ionization profiles, and the Pedersen and Hall conductances are calculated from fundamental equations. Appli- cations of the method to the distribution of the conductance at winter solstice in the course of substorm development over the north polar region will be illustrated. [less ▲]

This paper investigates the dynamical properties of the Eta model, a state-of-the- art nested limited-area model, following the approach previously developed by the present authors. It is first shown that the intrinsic dynamics of the model depends crucially on the size of the domain, with a non-chaotic behavior for small domains, supporting earlier findings on the absence of sensitivity to the initial conditions in these models. The quality of the predictions of several Eta model versions differing by their domain size is next evaluated and compared with the Avn analyses on a targeted region, centered on France. Contrary to what is usually taken for granted, a non-trivial relation between predictability and domain size is found, the best model versions be- ing the ones integrated on the smallest and the largest domain sizes. An explanation in connection with the intrinsic dynamics of the model is advanced. [less ▲]

In order to solve fast dynamic problems, an explicit method is the most adapted. But for slower dynamics, an implicit method is more stable. Typical industrial problems are governed by high frequency, e.g. impact, during short time intervals and slower dynamics, e.g. spring-back, during other time intervals. The optimal solution is then to have both implicit algorithm and explicit methods readily available in the same code and to be able to switch automatically from one to the other. Criteria that decide when to shift from a method to another have been developed here. Implicit balanced restarting conditions that annihilate numerical oscillations resulting for an explicit calculation are also proposed. [less ▲]

Le LabSET accompagne une vingtaine d'enseignants dans le portage à distance de leurs propres cours conventionnels, touchant plusieurs milliers d'apprenants au total. Défenseurs des pédagogies actives, nous prônons l'idée que l'EAD n'est qu'un vecteur, un support dont on peut faire le pire comme le meilleur. L'une de nos actions, FORMADIS , assure l'accompagnement de 13 projets d'EAD (projets sélectionnés en 2001 par appel à propositions) par un minimum de 2 chercheurs, du personnel technique et l'apport d'un graphiste. La formation pédagogique se déroule en partie en ligne et en partie en présentiel de façon à correspondre et donc à servir directement aux différentes étapes d'élaboration d'un cours à distance, selon les principes d'isomorphisme et d'accent systématique sur le transfert. Cet accompagnement nous semble un moyen efficace de participer à la formation continuée des enseignants. Des démonstrations à mi-parcours ont montré la diversité des méthodologies mises en oeuvre dans ces cours et la valeur ajoutée due à l'EAD. Plus de 40 activités sont passées au crible du modèle des 7 paradigmes d'enseignement / apprentissage. Un nouvel appel à propositions d'accompagnements de projets d'EAD est lancé par le LabSET en 2002. [less ▲]

Prior to the commercial availability of Very High Resolution (VHR) satellite imagery, the applicability of Earth Observation data in the urban planning sector was very limited. The spatial resolution of the imagery, supplied by platforms like Landsat TM and SPOT HRV, was too coarse to be of real practical use to urban planners and their applications. Satellite images of urban or sub-urban areas are characterized by large radiometric variations due to the small size and the diversity of the objects. This in turn causes a radiometric contamination between neighbouring pixels which renders object recognition nearly impossible. Satellite images with a higher resolution might alleviate this problem. The dawn of the VHR era was thus anticipated with great aspiration by urban remote sensing researchers. In the framework of a DWTC/OSTC Telsat 4 pilot project we proposed a methodology to employ IKONOS-21 imagery to develop an inventory of built-up, and un-built areas in Belgium’s Flemish region. Such an inventory can be of use to regional planning agencies that are responsible for the implementation of the government’s planning policies. In Flanders, AROHM (Administration of Spatial Planning, Housing, Monuments and landscapes) records, monitors, and evaluates the built-up areas. To do this, they need an extensive data input from the communities, which requires a lot of time and effort. A reliable and swift technique, based on earth observation data, and applicable for each residential area in Flanders, would be of great value to them. Not only would it allow them to make swift assessments more frequently, they could also double-check incoming data from the communities. The aforementioned project consisted of three parts: the visual interpretation of two study areas (Hasselt and Ghent), the automatic classification of these areas using both Maximum Likelihood and Neural Network classifiers, and the development of GIS procedures to transform the classified images into thematic maps like, for instance, a map of building densities.

High Speed Steel (HSS) cast rolls are used in front finishing stands of hot strip mills. Good wear resistance and hardness at high temperatures, are defining features of HSS. Many types of carbides are present in these alloys, each having different effect upon their final properties. As a result, nature, morphology and amount of these carbides are factors of important concern. Identification and characterisation of carbides were realised. MC, M2C, M7C3 carbides were found. Some relationships with mechanical properties were obtained especially in the field of the solidification sequence that affects grain size and carbides dispersion. [less ▲]

Ces dernières années, on a souvent décelé, dans les mythes, des traits initiatiques. Il s'agit là d'une possibilité d'explication utile, mais qui doit être maintenue dans des limites précises afin d'éviter des dérives fâcheuses. En ce qui concerne la mythologie grecque, il semble y avoir une tendance à distinguer deux niveaux d'initiation : 1) celle qui intéresse les adolescents qui doivent passer à l'âge adulte; 2) celle qui concerne un certain nombre de personnages extraordinaires. Dans le premier cas, il s'agit pour le jeune homme d'affirmer sa virilité en tuant un gibier, un ennemi ou un monstre redoutables. Il doit agir seul, mais des maîtres d'initiation peuvent lui apporter une aide secondaire et ils doivent juger de la réussite de l'épreuve. Dans le second cas, un être d'exception connaît une épreuve, souvent une mort réelle ou symbolique. S'il réussit l'épreuve, il acquiert une vertu particulière, éventuellement l'immortalité ou un succédané de celle-ci. Au cours de la seconde épreuve, le candidat peut être aidé par une divinité, dont le rôle est plus ou moins important et parfois décisif. Dans le présent article, on a rappelé qu'Ulysse avait successivement remporté le deux épreuves initiatiques, la première dans sa jeunesse en tuant un sanglier redoutable, et la seconde au cours de son périple qui le conduit dans l'autre monde. Examinant le rôle de son fils, Télémaque, particulièrement dans la Télémachie au début de l'Odysse, on est arrivé à la conclusion qu'apparemment Télémaque avait raté la première épreuve (son rôle à l'Assemblée d'Ithaque) et qu'il avait réussi la seconde (son voyage et son séjour à Pylos, puis à Sparte, est présenté comme un voyage dans l'autre monde, une sorte de réduction du périple de son père).

The stability of the casting process and the wear of the mould as well as the quality of the product depend strongly on the mould design. This is particularly true when considering the production of beam blanks. If the mould is too tight, thermal contraction can generate considerable contact forces between the product and the mould on the inner surfaces of the flanges. If it is not tight enough, the thermal coupling between the mould and the beam blank is not sufficient to allow the solidification of a skin of the required thickness upon exit from the mould. A finite element model was developed to assist in the mould design. This model takes both the thermal and mechanical interaction between the mould and the product into account. The effect of solidification is implicitly included in the (thermal) finite element formulation while the ferro-static pressure is applied by the means of a specially developed element. The model was applied to a medium gage beam blank cast at ProfilARBED Differdange. The skin thickness as well as the localisation of the wear of the mould predicted by the model are in good agreement with observations made in industrial practice. [less ▲]
