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 ▲]

Through a fourteen years retrospective study of all the patients treated at the State University of Liege, we have focused on the survival of 449 patients with, at least, a clinical stage 3 NSCLC disease (NORMS UICC). The whole study was divided in two periods (1972-1978, period 1, and 1979-1985, period 2) because, everything remaining nearly equal as far as the clinical material was concerned, period 2 was characterized by a different therapeutic attitude. Since 1979, the NSCLC stage 3's surgical indications have been widely extended. We have performed surgical resections in patients with NSCLC N2 disease because of positive homolateral mediastinal lymph nodes or with T3 disease. This led the NSCLC stage 3 resection rate to move from 26% in period 1 to 47% in period 2. We report here the effects of such a management on the short and long term survival and the stage 3 NSCLC global prognosis. We noted a modest significant increase in the NSCLC stage 3 global prognosis with a five year survival of 4% and 6% (period 1 and 2 respectively; P = 0.03). The 172 resected patients' outcome did not change (five year survival 11% (P1) and 12% (P2]. Although patients were not randomized, our results suggest that adjuvant therapy should not be added whenever the patient underwent a complete resection. On the other hand, it seems very useful indeed whenever the resection was partial. NSCLC patient at stage 3 who underwent a complete resection achieved a 37% five years survival. [less ▲]

An orthonormal basis of wavelets of $L^2(\R)$ is an orthonormal basis of $L^2(\R)$ of type \[ \psi_{j,k}=2^{j/2}\psi(2^j\cdot-k),\quad j,k\in\Z. \] A classical method to obtain such bases consists in constructing a multiresolution analysis. When the mother wavelet $\psi$ depends on the scale (i.e. the index $j$), a non stationary version of multiresolution analysis is then used. It is for example the case in the general context of Sobolev spaces. We generalize different characterizations in the standard theory of wavelets to the case of multi-scales wavelets and non stationary multiresolution analyses. [less ▲]
