Cet article porte sur la traduction intersémiotique du langage pictural dans l’image numérique. En particulier, les paysages analysés appartiennent à une série intitulée Orient et sont des traductions numériques de quelques chefs-d’œuvre de la peinture occidentale (Friedrich, Van Gogh, etc.). Ces images numériques ambitionnent de se poser comme summa de la culture de l’image occidentale et de sanctionner une tradition entière. Si les images numériques d’Orient apparaissent comme une étude diagnostique sur les chefs-d’œuvre picturaux du passé, cette même étude en numérique se révèle comme une pratique iconoclaste, dans la mesure où les stratégies énonciatives des œuvres numériques d’Orient produisent une dé-anthropomorphisation du geste instaurateur de la peinture. Le pouvoir iconoclaste des ces images numériques est directement lié à la pratique productive qui, non seulement efface la figuration de la peinture de l’âge moderne et contemporain, mais en nivelle les genres et les modi operandi.

Downsizing, restructuring and lay-offs have become recurrent practices among companies today. Whilst the consequences of such major changes on individual well-being are well documented, little is known about the nature of work environment changes. confronting workers and how they appraise these events. The objective of the present study was to combine quantitative and qualitative data in order to get a better understanding of organizational changes from a transactional perspective. Fifty-seven workers-from seven companies were interviewed. Interviews were transcribed and analyzed along three axes (a) What were the changes confronting workers ? (b) How did they react to these changes (c) How did they perceive the way their company dealt with these changes ? Results indicate that workers were mainly confronted with changes among colleagues and supervisors, changes in terms of workload as weft as task content. Moreover, it appears that not all changes were appraised negatively. With regard to the. consequences. reported by, workers, the findings reported in existing literature were generally supported by the current data. Workers reported a. general deterioration of their quality of life, a degradation of working climate and an increase in job insecurity as a result of organizational changes. Finally, workers indicated that the way companies managed changes was not really efficient. Workers complained mainly about information. They reported that they were either poorly informed or not informed at all about future changes. In conclusion, this study stresses the need for a qualitative analysis of the experience of workers confronted with organisational changes. [less ▲]

The paper draws on the survey led on 2.500 walloon people in collaboration with IWEPS in 2003-2004. It studies the impact of the belgian law that makes voting compulsory. If it was no longer teh case, who would go on voting ? Results of the survey shows that the constituency would differ rather strongly from what it is now : in particular, amnong the poor people and the less educated would many would drop voting. But it would be the case too of lonely people, for instance or people who feel unsecure. The result would be that the specific demands form those categories would loose much weight in the political process. [less ▲]

The paper studies the properties of a sinusoidally vibrating wedge billiard as a model for 2D impact juggling. It is shown that some periodic orbits that are unstable in the elastic xed wedge become exponentially stable in the (non-)elastic vibrating wedge. These orbits are linked with some classical juggling patterns, providing an interesting benchmark for the study of the frequency-locking properties in human rhythmic tasks. [less ▲]

The paper addresses the stabilization of periodic orbits in a wedge billiard with actuated edges. It is shown how the rich dynamical properties of the open-loop dynamics, e.g. ergodicity properties and KAM curves, can be exploited to design robust stabilizing feedbacks with large basins of attraction.

Multi-walled carbon nanotubes (MWNTs) have been successfully modified by polystyrene, poly(epsilon-caprolactone), and their block copolymers by addition reaction of the alkoxyamine-terminated precursors. Polymer-modified MWNTs are easily dispersed in good solvents for the grafted polymer, such as toluene and THF. This observation has been confirmed by TEM analysis. The grafting ratio of polystyrene chains at the surface of MWNTs depends on the polymer molecular weight. [less ▲]

Dynamical calculations are performed for all isomultiplets of the flavour antidecuplet to which the newly discovered pentaquark Theta(+) belongs. The framework is a constituent quark model where the short-range interaction has a flavour-spin structure. In this model the lowest pentaquarks have positive parity. Each antidecuplet member is described by a variational solution with the Pauli principle properly taken into account. By fitting the mass of Theta(+) of minimal content uudd, the mass of Xi(--), of minimal content ddss (u) over bar, is predicted at approximately 1960 MeV. The influence of the octet-antidecuplet mixing on the masses of the Y = I and 0 pentaquarks is considered within the same model and the role of the hyperfine interaction in this mixing is pointed out.

In the frame of cryogenic test on an off axis ellipsoid, it has been required to set-up an unambiguous method to determine and track the foci position during temperature transitions. This procedure was mandatory to avoid: (1) impact of the operator skills working on triple shift scheme to assure continuously monitoring of the ellipsoid shape during cool down. (2) correctly dissociate the impact of the thermal deformation on the mirror shape with respect to alignment errors. This paper will demonstrate the process, starting from ideal ellipsoid shape, then introducing 3D metrology data in a model, and finally presents the results in a practical situation. [less ▲]

Self-assembly of nonionic amphiphilic poly(ethylene oxide)-b-poly(ε-caprolactone) (PEO-b-PCL) and poly(ethylene oxide)-b-poly(γ-methyl-ε-caprolactone) (PEO-b-PMCL) has been studied in water by dynamic light scattering (DLS). The aqueous solutions have been prepared by three methods, i.e., dialysis of solutions in a common organic solvent against water, rapid addition of water to organic solutions, and rapid addition of organic solutions into water. Several common organic solvents have been used: tetrahydrofuran (THF), dimethylformamide (DMF), dimethylacetamide (DMAc) and dimethylsulfoxide (DMSO). The dialysis method is not reproducible and leads to very large and polydispersed particles (~1µm). In contrast, nanoparticles are formed by the two other methods with a low polydispersity and a size in the 30-10 nm range, depending on the organic solvent used. The particle size increases when the concentration in the organic solvent is decreased. The effect of temperature and length of the hydrophobic block has also been studied. [less ▲]

We discuss oxygen abundances derived from [O I] λ6300s and the O I triplet in stars spanning a wide range in chromospheric activity level, and show that these two indicators yield increasingly discrepant results with higher chromospheric/coronal activity measures. While the forbidden and permitted lines give fairly consistent results for solar-type disk dwarfs, spuriously high O I triplet abundances are observed in young Hyades and Pleiades stars, as well as in individual components of RS CVn binaries (up to 1.8 dex). The distinct behaviour of the [O I]-based abundances which consistently remain near-solar suggests that this phenomenon mostly results from large departures from LTE affecting the O I triplet at high activity level that are currently unaccounted for, but also possibly from a failure to adequately model the atmospheres of K-type stars. These results suggest that some caution should be exercised when interpreting oxygen abundances in active binaries or young open cluster stars.

During the three first months of the AQUATERRA project, the Group of Hydrogeology and Environmental Geology from the University of Liège (HGULg) has performed a general inventory of data sources and availability for the Walloon part of the Meuse basin in Belgium. This deliverable provides the information in the form of a summary table that gives a general description of data types, accessibility (public or confidential, free or charged…) and, if existing, a website with further useful information. In this synthesis, emphasis is put on hydrogeological information. However, general information on surface water is also provided when available. In the following months, needed data will be collected for the Meuse/Basin experimental sites in the Walloon region. Collected datasets will be introduced into the Hydrogeological Database HYGES developed by HGULg. This database is presently updated for the needs of the AQUATERRA Project. This synthesis will be further updated when new information and data sources are available. [less ▲]
