centrifuge classification des sables

 · Centrifuge modelling is a powerful tool for the study of geotechnical structures using reduced scale physical models. It is particularly relevant when stress gradient or free surface is important, like in arching phenomenon. In centrifuge modeling, the similarity of the conditions between the model (reduced scale) and the prototype (full scale) is guaranteed by the scaling .

Abstract. Centrifuge modelling is an advantageous technique to simulate the behaviour of helical anchors in sand. The uplift capacity of a singlehelix anchor is the sum of the helix bearing resistance plus the shaft resistance; therefore, recommendations to avoid the grainsize effect of previous model tests on plate anchors and on regular piles appear to be reasonable for helical .

 · A CNS echolaminergic cell line,, was established by targeted oncogenesis in transgenic mice. cells express neuronal properties but lack neuronal morphology. Here, we describe a variant of, called CAD (), in which reversible morphological differentiation can be initiated by removal of serum or exogenously added protein from the .

The centrifuge tests consisted of layers of compacted clay slabs separated by free draining layers. The study revealed that while the sandbentonite mixture possessed the potential to swell significantly, the time required to do so was impractical for centrifuge studies. It was however found that the approach used to create a scaled down fissured structure in the naturally .
