Peut-on réellement prétendre qu'en contexte de formation à distance (FAD) l'interactivité brise la distance ? En théorie, une démarche de conception de FAD axée à la fois sur le respect de critères ergonomiques, sur des stratégies et des outils stimulant l'activité des apprenants et la communication entre acteurs du dispositif va dans ce sens. Encore faut-il la mettre concrètement en oeuvre. Cet article traite de l'interactivité comme solution aux diverses contraintes rencontrées par les apprenants en situation de FAD. Les auteurs alimentent leurs réflexions au travers de champs disciplinaires variés tels que l'ergonomie des interfaces homme-machine, la psychopédagogie et la communication (synchrone et asynchrone). Dans chacun de ces champs, ils répertorient quelques bonnes pratiques pour la conception d'un dispositif de FAD « interactive ». [less ▲]

The fading of modern laboratory-synthesized and commercial Prussian blue, iron(III) hexacyanoferrate(II), based pigments in a linseed oil medium during exposure to light has been investigated. The Prussian blue pigments were painted from linseed oil, as a pure pigment and mixed with white lead, (PbCO3)2Pb(OH)2, zinc white, ZnO, or titanium white, TiO2, pigment. The samples were subjected to accelerated ageing for 800 hours and the light fastness of the Prussian blue pigment was evaluated by reference to blue wool standards. Pure Prussian blue is extremely light fast whilst it strongly fades when mixed with a white pigment, especially with lead white or zinc oxide. The painted samples were studied by UV-visible, iron K-edge X-ray absorption, iron-57 transmission Mössbauer, and attenuated total reflectance infrared spectroscopy. X-ray absorption results reveal a decrease in the iron coordination number in aged samples in the presence of white pigment. The Mössbauer spectra of the pure Prussian blue and the unaged and aged mixtures of Prussian blue and lead white or zinc oxide at 1:100 and 1:10 dilution ratios, respectively, indicate the presence of iron(II) and iron(III) in a ratio close to one as expected for the bulk stoichiometric KFeIII[FeII(CN)6]; no change in the spectral parameters was observed upon ageing. Combined with the X-ray near edge absorption and infrared studies, these results suggest reduction of the surface iron ions in the Prussian blue with ageing upon exposure to light. [less ▲]

A secoiridoid aglycone with atypical skeleton, named fagraldehyde (1), together with several known secoiridoids (gentiopicroside (2), sweroside (3) and swertiamarin (4)) were isolated from the bark and leaves of Fagraea fragrans collected in Cambodia. The conformations of 1 were evaluated on the basis of molecular modeling and NOESY correlations. A hypothetical biogenesis of fagraldehyde was proposed to explain the unusual skeleton. Compound 1 was weakly active in vitro against Plasmodium falciparum. [less ▲]

From some measurements of pH and hardness in melt-waters of the Marmolada Glacier (Dolomites), it appears that these waters are - or at least were in September 1965 - strongly alkaline and not very aggressive towards their limestone bedrock; pH on the glacier and just nearby are between 8.8 and 7.8. Calculated CO2 pressure is lower in the glacier (3.6 10 -4 atm) than in anyone of four other samples analysed in the region. [less ▲]
