À partir de la pratique photographique Cédric Martigny, cet article s’intéresse à représentation du travail par photographie. A travers plusieurs séries photographiques, j’analyserai deux modes opératoires mis en place le photographe : décontextualisation et transfiguration. Ces procédés permettent au s’appuyer sur les tenues gestes travailleur pour élaborer des mises-en-scène photographiques p...

In thermally enhanced recovery processes like cyclic steam stimulation (CSS) or steam assisted gravity drainage (SAGD), continuous steam injection entails changes in pore fluid, pore pressure and temperature in the rock reservoir, that are most often unconsolidated or weakly consolidated sandstones. This in turn increases or decreases the effective stresses and changes the elastic properties of...

Many mechanical and physical processes are associated with the generation of acoustic waves produced by the rapid release of energy from localized sources within a material. Acquiring and processing these waves allows non-destructive control of phenomena such as the extension of cracks in a structure under stress, plastic deformation, phase transitions, etc. Few works were devoted in past to ac...
