The effect of variety and moisture content on some engineering properties of five improved paddy rice varieties was investigated within moisture content range of 10% and 30% dry basis (d.b.). Increase in moisture content was found to increase the linear dimensions, mass of 100 seeds, surface area, apparent volume, true volume, arithmetic mean diameter, effective geometric diameter, sphericity, ...

Table des matières Résumé. Nous présentons dans cet article un outil de visualisation 3D, reposant sur des méthodes usuelles de construction de sous-espaces de représentation (ACP, MDS). L'originalité de notre approche repose sur l'utilisation de ce type de représentation dans le but de déterminer une métrique appropriée dans un cadre d'apprentissage supervisé : nous montrons en effet que l'org...

We show that, when a mixture of small and large grains is simply poured in a g̀ranular Hele± Shaw cell’ (two transparent slabs separated by a gap of about 5mm), the grains spontaneously stratify in alternating layers of small and large grains parallel to the surface of the pile. The spontaneous self-strati® cation occurs only when the large grains have a larger angle of repose than the small gra...

Résumé. Cet article présente la méthode et le système C3R pour vérifier de façon semi-automatique la conformité d’un projet de construction par rapport à des normes du bâtiment. Les projets de construction sont représentés par des graphes RDF et les normes par des requêtes SPARQL ; le processus de contrôle consiste en l’appariement des requêtes et des graphes. Son efficacité repose sur l’acquis...

We observe the formation of heaps of repulsive microspheres, created by flowing a colloidal microsphere suspension towards a flat-topped ridge placed within a quasi two-dimensional microfluidic channel. This configuration allows for both shear and normal forces on the microspheres in contact with the ridge. The heaps, which are formed against the ridge, are characterized by two distinct phases:...

Pressure ulcer prevention is expensive and at times difficult to achieve. Formation, or the potential formation, of pressure ulcers can lead to delayed patient discharge, particularly when the appropriate equipment is unavailable on the day of discharge. This article reviews the potential of Repose, an inflatable mattress overlay, to be an inexpensive and clinically effective alternative to alt...
