YBa2Cu3O7-δ thick films have been deposited onto Ag substrates by the Electrophoretic Deposition (EPD) technique. Different microstructures and electrical behaviours were observed depending on the starting powder. Coatings prepared from commercial powder displayed significant porosity and the superconducting transition width was found to be magnetic-field dependent. Films produced from home-made coprecipitated powder are denser but contain some secondary phases. No dependence of the resistive transition as a function of magnetic field (H ≤ 20 Oe) was observed in that case. [less ▲]

This article presents the validation results of a chiral liquid chromatographic (LC) method previously developed for the quantitative determination of R-timolol in S-timolol maleate samples. A novel validation strategy based on the accuracy profiles was used to select the most appropriate regression model, to assess the method accuracy within well defined acceptance limits and to determine the limits of quantitation as well as the concentration range. The validation phase was completed by the investigation of the risk profiles of various acceptable regression models in order to ensure the risk of obtaining the future measurements outside the acceptance limits fixed a priori. On the other hand, the present paper also shows how data used in this validation approach can be used to estimate the measurement uncertainty. The uncertainty derived from beta-expectation tolerance interval (sigma(Tol)(2)), which is equal to the uncertainty of measurements as well as the expanded uncertainty (U(x)) using a coverage factor k=2 was estimated. The uncertainty estimates obtained from validation data were finally compared with those obtained from interlaboratory and robustness studies. [less ▲]

De manière très schématique, on peut définir l'apprentissage en tandem de la manière suivante : il s'agit de mettre en contact deux élèves qui ne partagent pas la même langue maternelle et qui souhaitent apprendre la langue de l'autre. L'idée de base est que chacun des élèves "enseigne" sa propre langue à son partenaire. On distingue deux formes d'apprentissage en tandem. 1) le tandem à distance ou tandem virtuel qui consiste à demander aux élèves de s'échanger des lettres, des e-mails et/ou divers autres documents (articles de journaux/revues, photos, cassettes vidéo/audio, CD, etc.) 2) le tandem physique qui permet aux élèves de se rencontrer physiquement dans un, voire dans les deux pays partenaires. L'originalité de l'apprentissage en tandem se situe avant tout dans la démarche de systématisation des échanges et dans la méthodologie préconisée pour amener les élèves partenaires à apprendre la langue étrangère de et avec l'autre.

A routine and low cost method to collect pore water in a seagrass meadow in situ and underwater is here proposed. The method consists of direct-suction filtered sampling allowing the determination of nutrient concentrations in the sampled water. Data ranges of nutrient (NO2-+NO3-; HPO4 2- and NH4+) concentrations in a P. oceanica meadow are also discussed [less ▲]

This communication reports experimental results on the superconducting properties of YBaCuO thick films prepared by electrophoretic deposition on silver substrates. The magnetic shielding properties of the coatings were characterised by various methods. First, the electrical resistance and the transport critical current density, Jc, were determined. Our coatings exhibit a superconducting transition at a temperature of 90 K. Next, shielding characterisations were carried out at 77 K for samples having either a slab or a cylindrical geometry. In both cases, the frequency of the applied magnetic field was 103 Hz; the field behind the shielding wall was measured by a pick-up coil connected to a lock-in amplifier. In the case of cylindrical samples and for an applied induction lower than 1 G, the field inside the shielding enclosure is reduced by a factor greater than 106 (i.e. 120 dB) with respect to the applied field.

We showed previously that the proneural genes Neurogenin1 (Ngn1) and Ngn2 are required to specify the phenotypes of early- and not late-born neurons in the neocortex, acting in part through repression of Mash1, a third cortically expressed proneural gene. The precise timing of Ngn1/2 specification activity was unexpected given these genes are expressed throughout cortical development, prompting us to search for a later function. Here we reveal that Ngn2 and Mash1 are expressed in a dynamic fashion, acquiring a cell cycle-biased, nonoverlapping distribution, with preferential expression in prospective basal progenitors, during mid corticogenesis. We also identified a new function for Ngn2 during this latter period, demonstrating that it is required to regulate the transit of cortical progenitors from the ventricular zone (VZ) to the subventricular zone. Notably, Ngn2 regulates progenitor maturation at least in part through repression of Mash1 as misexpression of Mash1 strongly enhanced progenitor cell exit from the VZ. Significantly, the ability of Mash1 to promote progenitor cell maturation occurred independently of its ability to respecify cortical cells and is thus a novel function for Mash1. Taken together, these data support a model whereby Ngn2 and Mash1 function together to regulate the zonal distribution of progenitors in the developing neocortex. [less ▲]
