Shearography is a growing optical technique in the field of non-destructive testing (NDT). Hololab developed an out of plane, in line and almost common path interferometer based on polarization states separation using a coated prism for digital phase-shifting shearography. This setup is efficient but does not allow varying the shearing direction, that is an important parameter for defects detection and quantification. To overcome this disadvantage, the coated prism is substituted by a Savart plate device that allows scanning several shearing directions by rotating the device around the light propagation axis. Many advantages of the prism substitution are discussed. The behaviour of the Savart plate as a shearing device is experimentally analyzed to optimize its integration within the interferometer. Recorded phasemaps in NDT for different shearing directions are presented. [less ▲]

In the context of a non linear quasi-steady wind loading, this paper shows the importance of the non linearity of the wind loading. More particularly, it focuses of the influence, on the structural response, of the non linearity of the aerodynamic coefficients. It is shown that, in case of 2-D turbulent flow, the influence of this kind of non linearity may be significant. To do so, statistical characteristics of the loading as well as those of the response are computed in such a turbulent flow. [less ▲]

When submitted to mercury porosimetry, some materials are penetrated by mercury whereas others, among the most porous, are densified by the isostatic pressure. Notably, this is the case for materials whose structure is made of particles aggregated into filament-like clusters that are interconnected in a 3-D array. Indeed, that kind of material undergoes a volume variation due to hierarchical pore collapse. In the case of intrusion, the mercury porosimetry data are classically analyzed by the Washburn equation. In the case of hierarchical pore collapse, data can be correctly analyzed by the collapse model equation. Using an equation that does not correspond to the mechanism leads to large errors in the pore size distribution. Thus, an accurate data analysis requires prior determination of the mechanism leading to the volume variation recorded as a function of the pressure. The present work particularly examines the complex and unusual behavior of partially pyrolyzed resorcinol-formaldehyde gels when submitted to mercury porosimetry. The unusual behavior encountered complicates the mechanism identification and, therefore, the equation selection. However, the major part of the volume distribution as a function of the pore size can be determined with a good accuracy. [less ▲]

Elevated free fatty acid concentrations are known to decrease insulin-mediated glucose uptake, glucose oxidation and glycogen synthesis. In order to determine whether free fatty acids inhibit glycogen synthesis at the level of liver cells, the effects of an infusion of lipids on carbohydrate metabolism were investigated in healthy subjects during a two-step (16.7 and 33.4 mumol/(kg.min) 13C-fructose infusion. Fructose infusion dose-dependently stimulated fructose (measured from 13CO2 production) and net carbohydrate oxidation (measured with indirect calorimetry). It also stimulated systemic 13C glucose appearance, indicating a dose-dependent stimulation of gluconeogenesis. Net glucose output (measured with 6,6 2H glucose) was however not altered. Lipid infusion significantly reduced fructose oxidation (measured from 13CO2 production) at both rates of fructose infusion, but did not alter plasma fructose or lactate concentrations, nor plasma 13C glucose appearance or net glucose production. Non oxidative fructose disposal was increased by 31% (p < 0.05) at the lowest, and by 18% (p < 0.01) at the highest infusion rate. Since nonoxidative fructose disposal corresponds mainly to liver glycogen deposition, these results suggest that lipid infusion increased hepatic glycogen synthesis, and hence that hepatic glycogen synthase is not inhibited by fatty acids.

(Extrait) : On envisagera ici le médium artistique de la performance sous l’angle de sa non-performativité1. En tant que courant historiquement identifiable, dont le happening constitue un ancêtre reconnu, la performance se définit minimalement par l’exécution d’actions élevée au statut de proposition artistique. Afin de respecter la liberté d’interprétation du spectateur, l’artiste performeur se met délibérément en condition de n’avoir pratiquement pas de prise sur les effets qu’il produit. La conséquence directe d’une telle mise en suspens concerne bien entendu la réception de l’œuvre : le spectateur n’est pas guidé par l’artiste dans la lecture de ses intentions. En sapant volontairement les effets de maîtrise généralement liés à l’exercice artistique, les performeurs génèrent des événements dont la portée critique est non négligeable. La performance, en particulier dans le cas des performances collectives dites «open sessions»2, produit des événements sauvages et anarchiques sur lesquels l’imagination peut venir se greffer librement et exercer sa puissance de manière débridée. Une théorie renouvelée de la réception, basée sur l’identification du rapport critique de la non-performativité à l’imagination, devrait pouvoir s’élaborer à partir de ce médium. [less ▲]
