For the hydrological modeling of forested watersheds, the understanding of the forest hydrodynamic is essential. This study focusses on the hydrology of a Belgian forested plot with high stoniness and steep slope. The soil water content is monitored at several positions on the toposequence and at different depth. During rain events, peak in soil water content are observed in different depth depending on the position along the toposequence. [less ▲]

Le photogramme est, au cinéma, la plus petite unité de prise de vue. Image fixe, unité élémentaire du film, le photogramme forme la cellule figée d’un mouvement qui se reconstitue sous l’effet d’un défilement réglé (24 photogrammes/seconde) par le dispositif technique du cinéma. Image paradoxale en ce qu’elle reste invisible au spectateur malgré sa force iconique, le photogramme trouve cependant, dans le flux qui le conduit insensiblement à la disparition, certaines zones de visibilité qui en révèlent le caractère à la fois fragile et intensif. Nous allons donc envisager certaines pratiques ou certains usages du photogramme cinématographique, tout en essayant de dégager, au départ de ces pratiques, les éléments d’une théorie du photogramme, que Roland Barthes et Sylvie Pierre appelaient déjà de leurs vœux. Des protos-photogrammes et de leur usage scientifique chez Muybridge et Marey, aux usages artistiques contemporains, en passant par des pratiques publicitaires, promotionnelles ou analytiques, nous allons voir que le photogramme reste un objet singulier.

This text focuses on how teachers and other institutional actors (such as headmasters, psychologists and social workers) offer guidance to pupils in secondary schools. It stresses the epistemological and empirical challenges inherent in a study of decisionmaking in school guidance as used by teachers, based on field theory. The text begins with a presentation of several sociological studies of how teachers construct their judgments about pupils. It emphasizes the strength of the concept of field as a key to understanding the role played by teachers in the formal process of educational (school) guidance, specifically in the case of the French "Grandes Ecoles". This section goes on to show that, with the weakening of the autonomy of (the) educational institutions, (the) French sociology of education moved away from (the) Bourdieu’s perspective, (and) to focus(ed) on the moral pluralism inherent in education and the ethical tensions that institutional actors face. The second part of the text discusses the findings of socioanthropological fieldwork undertaken in secondary schools in the French Community of Belgium. This section argues that the dynamics of judgments made by teachers today canbest be understood through their structural linkages with the structure of the field of secondary education. [less ▲]

L’utilisation de la Blattmaske dans les décors pariétaux peints se fait selon diverses modalités. Pour en comprendre pleinement le sens, il convient de considérer le motif dans son contexte ornemental et architectural. Il s’agit tout d’abord de préciser le mode d’insertion des « têtes végétalisées » dans le reste de la décoration de la paroi. Car s’il est vrai qu’elles peuvent faire l’objet d’un jeu formel, elles ne doivent pas pour autant être considérées comme de purs éléments décoratifs. La mise en série dans des bandes « ornementales », l’isolement dans un cadre, ou encore le positionnement stratégique à un endroit clef d’une composition, accordent en effet au motif différents niveaux de lecture. L’analyse conjointe du décor ambiant permet par ailleurs de préciser davantage l’interprétation de l’image. Les Blattmasken se voient effectivement associées à différents motifs, parmi lesquels les êtres hybrides, ou encore les scènes marines ou dionysiaques. Enfin, il convient de préciser le contexte architectural dans lequel le motif est employé, la portée du message véhiculé par le programme décoratif dépendant de la fonction de la pièce et du bâtiment.

The copolymerization of ε-caprolactam with ethyl 4-(butylamino)benzoate was shown to occur in the presence of sodium salts and an acyllactam as activator in a one-step bulk reaction. The mechanism is based on the deprotonation of the two monomers yielding activated species able to attack an acyllactam or an ester group at the polymer chain ends. Novel copolyamides with different percentages of aromatic/aliphatic units were synthesized in a one-step bulk copolymerization within a few minutes at 140 °C and characterized by NMR spectroscopy, size exclusion chromatography, and thermal analysis (DSC). This methodology, combining simultaneous anionic ring-opening and condensation reactions, affords a new synthetic pathway to introduce an aromatic unit in an aliphatic polyamide backbone, and more specifically a polyamide 6 containing about 20 mol % of N-alkyl aromatic amides was prepared.

Context. It is now generally accepted that the near-infrared excess of Herbig AeBe stars originates in the dust of a circumstellar disk. Aims. The aims of this article are to infer the radial and vertical structure of these disks at scales of order one au, and the properties of the dust grains. Methods. The program objects (51 in total) were observed with the H-band (1.6micron) PIONIER/VLTI interferometer. The largest baselines allowed us to resolve (at least partially) structures of a few tenths of an au at typical distances of a few hundred parsecs. Dedicated UBVRIJHK photometric measurements were also obtained. Spectral and 2D geometrical parameters are extracted via fits of a few simple models: ellipsoids and broadened rings with azimuthal modulation. Model bias is mitigated by parallel fits of physical disk models. Sample statistics were evaluated against similar statistics for the physical disk models to infer properties of the sample objects as a group. Results. We find that dust at the inner rim of the disk has a sublimation temperature Tsub~1800K. A ring morphology is confirmed for approximately half the resolved objects; these rings are wide delta_r>=0.5. A wide ring favors a rim that, on the star-facing side, looks more like a knife edge than a doughnut. The data are also compatible with a the combination of a narrow ring and an inner disk of unspecified nature inside the dust sublimation radius. The disk inner part has a thickness z/r~0.2, flaring to z/r~0.5 in the outer part. We confirm the known luminosity-radius relation; a simple physical model is consistent with both the mean luminosity-radius relation and the ring relative width; however, a significant spread around the mean relation is present. In some of the objects we find a halo component, fully resolved at the shortest interferometer spacing, that is related to the HAeBe class. [less ▲]
