We explored rates and stoichiometry (C: N: P ratios) of sinking particles in a temperate reservoir during a 2-yr period. Plankton was sampled weekly, and a sediment trap placed below the metalimnion collected sinking particles. There were no significant relationships between the stoichiometry of entrapped material and seston or zooplankton stoichiometry. However the differences in the entrapped C: P and N: P ratios between consecutive trap samplings were negatively correlated with the time variations of the zooplankton C: P and N: P ratios. Zooplankton C: P and N: P ratios were positively correlated with the percentage of copepod biomass in total zooplankton biomass > 250 mu m and negatively correlated with the percentage of cladocerans. Zooplankton biomass > 250 mu m reduced the fraction of N and P primary production lost to sinking (export ratio). The residuals of the N export ratio versus zooplankton biomass relationship were negatively correlated with the zooplankton N: P ratio, whereas there was a positive relationship with the residuals of the P export ratio relationship. These observations support the hypothesis that the regulation of elemental homeostasis in the herbivorous zooplankton consumers occurs at least partly at the assimilation/egestion level. Elements ingested in excess-P for the herbivorous copepods and N for many cladocerans-are concentrated into sinking feces, whereas the deficient elements are captured into biomass. [less ▲]

The economic and climate contexts require to use more electricity from wind farms. However this kind of production is intermittent, therefore it is necessary to forecast this resource at least 1 day ahead. Our laboratory has developed a forecasting model of wind-based electricity generation based on a global meteorological model (GFS) with a resolution of 50 km and 3 h. But this model has a resolution too coarse for a wind farm. So we have configured the regional model WRF with resolution of 2 km and 15 min to obtain better forecasts. Finally, the WRF model provides better forecasts, but both must be adjusted to take into account the direct environment of the wind farm. [less ▲]

Investigated the influence of methodological conditions (i.e., time-blind evaluation, chronological vs random order, and suppression of the time gap between evaluations) on the objectivity and sensibility of quantitative evaluation of psychopathology. Different evaluations of videotaped interviews did not demonstrate systematic effects of these temporal conditions. It is suggested that other variables (monotony, order of sequences, verbal inertia, contingencies) may play a greater role. Within the methodological limits of the present study, the time-blind evaluation was the most sensitive [less ▲]

au bout du compte, l'offre d'emploi faite aux femmes et les débuts de trajectoires professionnelle auxquelles elles ont accès jouent plus sur leurs carrières que les facteurs familiaux. Si les femmes peu diplômées restent aujourd'hui particulièrement exposées au non emploi (sans comparaison avec ce qui se passe pour les hommes dans ce cas), l'ensemble des femmes connait un risque élevé de commencer leur trajectoire professionnelle dans des emplois atypiques et de s'y enliser (significativement beaucoup plus que les hommes)....

We examine the variation in the radius of the auroral oval, as measured from auroral images gathered by the Imager for Magnetopause-to-Aurora Global Exploration (IMAGE) spacecraft, in response to solar wind inputs measured by the Advanced Composition Explorer (ACE) spacecraft for the two year interval June 2000 to May 2002. Our main finding is that the oval radius increases when the ring current, as measured by the Sym-H index, is intensified during geomagnetic storms. We discuss our findings within the context of the expanding/contracting polar cap paradigm, in terms of a modification of substorm onset conditions by the magnetic perturbation associated with the ring current.

Physical and chemical properties vary with temperature. In a sliding contact between a pair of materials, high speeds can provoke a rise of the temperature of these materials due to the heat produced by friction. Consequently, the increase of temperature can modify physical and chemical properties affecting their tribological behaviour. Tribological tests performed on polyimide resins sliding against austenitic stainless steel indicate that there is a friction transition which is temperature dependent. A wear transition accompanying the friction transition was not observed. The tests were performed during a research campaign developed in order to investigate the behaviour of some pairs of materials which can be used in a tightness or a bearing function for valves in aerospace applications.
