Le boire caché des femmes et hommes alcooliques. Le genre sous la normalisation et la dissimulation

2022

Alors que la cachette est perçue socialement comme un trait général de l’alcoolisme, celle-ci peut basculer comme une spécificité de l’alcoolisme féminin. À partir d’une série de récits de vie et d’observations recueillies au sein d’un Centre de Soins de Suite et de Réadaptation en Addictologie, ce travail se concentre sur les discours de différenciation de genre mais aussi sur les pratiques liées à la dissimulation des alcoolisations. L’alcoolisation cachée reste la clé de voûte de l’ensemble des contradictions que comporte le système de représentations genrées sur l’alcoolisme. Aussi, il importe de mieux cerner dans les pratiques ce que l’on cache, comment on le cache, à qui l’on cache et…

Dynamics of hydrofracturing and permeability evolution in layered reservoirs

2015

International audience; A coupled hydro-mechanical model is presented to model fluid driven fracturing in layered porous rocks. In the model the solid elastic continuum is described by a discrete element approach coupled with a fluid continuum grid that is used to solve Darcy based pressure diffusion. The model assumes poro-elasto-plastic effects and yields real time dynamic aspects of the fracturing and effective stress evolution under the influence of excess fluid pressure gradients. We show that the formation and propagation of hydrofractures are sensitive to mechanical and tectonic conditions of the system. In cases where elevated fluid pressure is the sole driving agent in a stable tec…

Inhibition of Protein Isoprenylation Impairs Rho-Regulated Early Cellular Response to Genotoxic Stress

2000

Activation of c-Jun N-terminal kinases (JNKs) and nuclear factor-kappaB (NF-kappaB) are early cellular responses to genotoxic stress involved in the regulation of gene expression. Pretreatment of cells with the hydroxymethyl glutaryl-CoA reductase inhibitor lovastatin blocked stimulation of JNK1 activity by UV irradiation and by treatment with the alkylating compound methyl methanesulfonate but did not affect activation of extracellular signal-regulated kinase 2 by UV light. Lovastatin also attenuated UV-induced degradation of the NF-kappaB inhibitor IkappaBalpha. The effects of lovastatin on UV-triggered stimulation of JNK1 as well as on IkappaBalpha degradation were reverted by cotreatmen…

Pavement Management System model using a LCCA- microsimulation integrated approach

2014

The maintenance and the rehabilitation of the urban road pavements are not often based on systematic program and scheduling but rather on emergency or on other not identified reasons. Moreover the Life Cycle Cost Analysis (LCCA), the only peculiar procedure for the management pavement, finds its own application for highway and motorway, even if it is possible to search the best investment for the urban interstate and arterials. By the light of the quantity of the involved resources, it seems necessary to define an operative methodology for programming the maintenance and rehabilitation activities for the urban pavement. The paper is oriented towards the development of a multidisciplinary ap…

A multidisciplinary approach using LCCA and micro-simulation 10 model for the management of the urban pavements

Experimental Observation of a Large Low-Frequency Band Gap in a Polymer Waveguide

2018

The quest for large and low-frequency band gaps is one of the principal objectives pursued in a number of engineering applications, ranging from noise absorption to vibration control, and to seismic wave abatement. For this purpose, a plethora of complex architectures (including multiphase materials) and multiphysics approaches have been proposed in the past, often involving difficulties in their practical realization. To address the issue of proposing a material design that enables large band gaps using a simple configuration, in this study we propose an easy-to-manufacture design able to open large, low-frequency complete Lamb band gaps exploiting a suitable arrangement of masses and stif…
