The aim of this study is to compare the effect of different homogenization treat- 12 ments on the physicochemical properties and the hydrolysis rate of a pure bleached 13 cellulose. Results obtained show that homogenization treatments improve the enzymatic 14 hydrolysis rate of the cellulose fibers by 25 to 100 %, depending of the homogenization 15 treatment applied. Characterization of the samples showed also that homogenization had an 16 impact on some physicochemical properties of the cellulose. For moderate treatment inten- 17 sities (pressure below 500 b and degree of homogenization below 25), an increase of water 18 retention values (WRV) that correlated to the increase of the hydrolysis rate was highlighted. 19 Result also showed that the overall crystallinity of the cellulose properties appeared not to be 20 impacted by the homogenization treatment. For higher treatment intensities, homogenized 21 cellulose samples developed a stable tridimentional network that contributes to decrease 22 cellulase mobility and slowdown the hydrolysis process.

A previous study highlighted the effect of vocal technique on the singing voice accuracy of trained singers (1). The intervals' precision between the notes of the tune was altered when the singers used Western operatic singing technique. In order to better understand these results, we have recorded two different melodies sung with two different vocal techniques. A large panel of trained singers (N = 50) participated in the study. The analytical method described in the reference paper (1) has been applied. The results confirm the effect of vocal technique on the vocal accuracy of trained singers. In addition, these results provide an answer about the melodic effect and guide future work on the perception process of operatic voices. [less ▲]

In North Kivu, D.R. Congo, cattle are raised in extensive systems based on local breeds and crossbreds. This farming method affects the performance of dairy animals and mortgages the level of milk consumption in population. An improved farming system, including feed supplementation, Friesian cross-breeding and the sheltering of animals in stalls at night, was studied to evaluate its effect on milk production by Ankole x Friesian crossbreds. The study was performed in Beni, D.R. Congo, on two groups of 15 animals (control group-CoG and improved group-IG), homogeneous according to Friesian blood and parity levels. The improved system, Friesian blood and parity levels increased significantly milk production (P<0.001). Farming system increased milk production by 1.6 l/d (5.2 l/d vs 6.8 l/d respectively in CoG and IG). Milk production ranged from 5.3±0.04 l/d to 6.6±0.02 l/d and from 4.9±0.02 l/d to 7.2±0.02 l/d according, respectively, to Friesian blood level and parity. A significant interaction was observed between farming system and Friesian blood level, and between farming system and parity (P<0.001). The two groups were characterized by a fair adaptation to forage availability associated to climatic factors. The study showed the importance of genetic and environmental factors on the milk production of crossbred dairy cows of the region. [less ▲]

Cet article expose le développement d’une méthodologie automatique pour la détection des changements du bâti en vue d'une mise à jour semi automatique des cartes urbaines. L'approche est basée sur la comparaison entre une carte existante et une image à très haute résolution spatiale (THRS) récente. Elle s'enchaine sur 4 étapes. D'abord l'image est segmentée pour produire des primitives. Ces dernières sont caractérisées par 4 catégories d'attributs. Des classifieurs avancés par apprentissage supervisé (CAAS) ont été utilisés dans l'étape de la classification. Le paramétrage optimal de ces classifieurs est obtenu automatiquement par validation croisée en se référant au meilleur taux d'erreur. La prédiction finale des objets est déduite par un combineur de multiples classifieurs (CMC) conçu à partir des 3 meilleurs CAAS. Enfin, une étape de détection des changements permet d'identifier les primitives qui représentent les changements du bâti. Les données utilisées concernent la ville de Rabat (Maroc). Une image QuickBird a été utilisée avec un plan existant à l'échelle 1:10,000. Indépendamment de la qualité de la forme des bâtiments détectés, la méthode offre des meilleurs taux en exhaustivité (91.7%) et en exactitude (81.5%). [less ▲]

L’image, sous ses divers aspects, a joué un rôle essentiel dans la vie des anciens Grecs, en particulier dans le domaine religieux, puisque elle était l’une des modalités de perception du divin. En Grèce, la figuration anthropomorphe des dieux est largement majoritaire. Toutefois, en se tournant vers un support particulier, le vase peint, et un type de représentation particulier, la statue divine, on montrera ici que l’anthropomorphisme a pu amener une certaine ambiguïté. Dans la céramique, les représentations de statues fonctionnent sur plusieurs modes, selon la chronologie. C’est ce que l’on propose d’analyser, en examinant un groupe de vases décorés d’un thème semblable et sur lesquels une divinité est représentée, mais soit sous la forme d’une figure « vivante », soit d’une statue plus ou moins bien caractérisée. Cette étude permettra d’aborder les concepts de « fixité » et de « mouvement » de/dans l’image, mais aussi d’explorer quelques pistes de réflexions sur l’image divine et, plus largement, sur les modes de représentation du divin en Grèce ancienne.

The presence of pulsations influences the local parameters at the surface of massive stars and thus it modifies the Zeeman magnetic signatures. Therefore it makes the characterisation of a magnetic field in pulsating stars more difficult and the characterisation of pulsations is thus required for the study of magnetic massive stars. Conversely, the presence of a magnetic field can inhibit differential rotation and mixing in massive stars and thus provides important constraints for seismic modelling based on pulsation studies. As a consequence, it is necessary to combine spectropolarimetric and seismic studies for all massive classical pulsators. Below we show examples of such combined studies and the interplay between physical processes. [less ▲]
