Based on the Belgian soil map at 1/20,000, this digital map of Wallonia (DSMW) is composed of a cartographic database describing the soil characteristics of the region. Tool for a better soil management, this database will be integrated in a geographical information system where the soil layer could be used in relation with information concerning other aspects of land development. The different operations include : map drawing finalization of non edited sheets, creation of an image layer, vectorial capture of source objects, building up of the topology, characterization of the objects, geometrical corrections, creation of a continuous layer (edge-matching), creation of a homogeneous legend, integration in a geodatabase. The DSMW in figures corresponds to : 16,000 km2; 600,000 soil polygons delimited by 15 million intermediate points (vertex); 6,000 pedological symbols; 700MB. The advantages of this computerized cartographic database are continuity, legibility, accessibility and many possibilities of thematic analyses. [less ▲]

Tilted thick sections (one-half to several micrometers) of biological specimens observed with medium- to high-voltage electron microscopes are extremely useful for the study of the three-dimensional (3-D) structure of organelles. If high resolution in 3-D visualization and 3-D reconstruction is needed, many images corresponding to various angles of rotation and tilt must be recorded. This necessitates very time-consuming work--including eventual photographic processing--before good positioning of the object is defined. We have developed software which permits very rapid and precise determination of the tilt-axis, the registration of tilted views, 3-D measurements and 3-D visualization. Images are digitized either from negative films or directly with a camera fitted to the microscope. The application of the software is performed in minutes and allows for a rapid check of the quality of the tilt-series and of the features of interest of the object. Application of the software to the study of the 3-D structure of active components of the nucleolus stained with silver is shown. [less ▲]

Dihadron fragmentation functions describe the probability that a quark fragments into two hadrons plus other undetected hadrons. In particular, the so-called interference fragmentation functions describe the azimuthal asymmetry of the dihadron distribution when the quark is transversely polarized. They can be used as tools to probe the quark transversity distribution in the nucleon. Recent studies on unpolarized and polarized dihadron fragmentation functions are presented, and we discuss their role in giving insights into transverse spin distributions. [less ▲]

We present preliminary results for an updated extraction of the transversity parton distribution based on the analysis of pion-pair production in deep-inelastic scattering off transversely polarized targets in collinear factorization. Data for proton and deuteron targets by HERMES and COMPASS allow for a flavor separation of the valence components of transversity, while di-hadron fragmentation functions are taken from the semi-inclusive production of two pion pairs in back-to-back jets in e+e- annihilation. The latter data from Belle have been reanalyzed using the replica method and a more realistic estimate of the uncertainties on the chiral-odd interference fragmentation function has been obtained. After encoding this piece of information into the deep-inelastic scattering cross section, the transversity has been re-extracted by using the most recent and more precise COMPASS data for proton target. This picture represents the current most realistic estimate of the uncertainties on our knowledge of transversity. The preliminary results indicate that the valence up component seems smaller and with a narrower error band than in previous extraction. © 2015 Owned by the authors, published by EDP Sciences.

A simplified model for the prediction of the steady-state outflowthrough a breach in an inland dike is presented. It consists in the application of the mass and momentum conservation principles to a macroscopic control volume. A proper definition of the shape of the control volume enables to take the main characteristics of the flow into account and thus to compensate for the extreme simplification of the spatial representation of the model. At the breach, a relation derived from the shallow-water equations is used to determine the direction of the flow. Developments have been guided by numerical simulations and results have been compared to experimental data. Both the accuracy and the domain of validity of the simplified model are found satisfactory. [less ▲]

Cette étude est consacrée à la formation du graphite dans des fontes à haute teneur en chrome (8%) et spécialement à la détermination des conditions de formation de graphite secondaire par des traitements thermiques adaptés. La solidification de la fonte étudiée a été examinée par analyse thermique différentielle (ATD). Les effets d'un traitement à haute température ont été examinés à la fois par calorimétrie et dilatomètre différentielle. Le graphite primaire se forme vers 950°C. Le graphite secondaire précipite sur le graphite primaire lors du traitement de déstabilisation de l'austénite à haute température. La forme et la quantité de graphite secondaire dépendent de la température de traitement. [less ▲]

The interest of small additions of Cr (< 3 wt %) and Mo (~ 0.2 wt %) in steels for automotive and bearing applications has been recently highlighted. The microstructure of these steels is primarily based on the bainitic phase. In order to optimize their microstructure and their mechanical properties, it is, therefore, of primary importance to gain a better understanding of the influence of Cr and Mo on austenite decomposition in varying temperature regimes with a particular attention to the transition between ferrite, bainite and martensite formation. In the present work, dilatometry, combined with detailed microstructural characterisation, is used in order to obtain a full view of transformation processes and kinetics in two medium-carbon steels with and without Cr and Mo additions.
