Nous proposons d'abord une étude comparative des définitions des quartiles données dans la littérature et mettons en évidence les divergences de vues des différents auteurs. Nous nous intéressons également aux méthodes de calcul proposées par différents logiciels de statistique. Ensuite, nous proposons une définition du premier quartile qui permette de rester en cohérence avec la définition de celui-ci dans le cas d'une variable quantitative continue. [less ▲]

Cette étude avait pour objectif de caractériser, qualitativement, les synergies entre associations émargeant aux domaines de compétences de la Communauté française, principalement. Elle a pour objectif de comprendre finement les mécanismes en oeuvre tant dans la mise sur pied d’actions concrètes de collaboration, les synergies, que dans leur financement éventuel, pour ce qui se nomme alors des synergies avec transversalité.

The authors have examined the technological feasibility of laminating small sized logs (girth at breast height between 70 and 150 cm) of European oaks (Quercus robur L. and Quercus petraea LIEBL.). This technique allows indeed to produce from a low grade raw material a product able to compete with solid wood of first choice. The manufacturing of window frames has been taken as an example of the use of laminated oak. The observed output from the sawing of the experimental material seems to point out that only the logs belonging to the girth categories between 105 and 145 cm are really able to be upgraded by this process (output ranging from 19 % up to 28 %). The shrinkage measurements show that the processed raw material is characterized by a low dimensional stability. The effect of the wood species and the kind of glue on the mechanical behaviour of the product has been investigated. Oak has a lower bending strength than merbau but higher than meranti or larch from Oural. Considering the different glues used for this experiment, it has been observed that they give in "dry state" a higher shear strength than solid wood. However, moisture induces to a variable extent a strength loss for all the compared wood adhesives. [less ▲]

In a previous work, we demonstrated that palatine processes treated with 10 micrograms/ml neuraminidase for 30 minutes at 37 degrees C show a delayed fusion in vitro. In order to investigate the effects of neuraminidase, the treated palatine processes were observed with the aid of transmission and scanning electron microscopy. The effect of neuraminidase is exclusively detectable on superficial flat cells of the palatine processes, especially the cells of the medial edge of the process. The epithelial basal cells remain unchanged. Observed with the S.E.M., the superficial epithelial cells show bubbles, become spherical and detached. To explain these observations, we namely propose the following hypothesis: the action of neuraminidase prevents the fusion of the palatine processes because it denudes basal cells bearing a too immature cell coat for ensuring sufficient adherence between the palatine processes.
