Génération et détection sans contact des ondes de Rayleigh par méthodes ultrasons-laser et EMAT en mode statique et dynamique : application à la détection de défauts surfaciques dans le champignon du rail, Non-contact generation and detection of Rayleigh waves by laser-ultrasonics and EMAT methods in static and dynamic modes : application to the detection of surface defects in rail heads

Bada Ndao

Les squats et les head-checks sont des défauts générés par l’endommagement des rails dû à la fatigue de contact de roulement, ils sont localisés à la surface du champignon du rail. La possibilité de les détecter en modes statique et dynamique lorsque leur profondeur se situe sous le seuil critique…, Squats and head-checks are a form of near surface rolling contact fatigue damage found in rail heads. The ability to detect these defects in static and dynamic modes when their depth is under the critical threshold of 5 mm represents a major challenge for the rail industry. Conventional inspection…

Experimental study of acoustic noise correlation technique for passive monitoring of rails

Laïd Sadoudi, Emmanuel Moulin, Jamal Assaad, Farouk Benmeddour, Michael Bocquet, Yassin El Hillali

The work presented in this paper aims at investigating the ability of acoustic noise correlation technique for railway infrastructure health monitoring. The principle of this technique is based on impulse responses reconstruction by correlation of random noise propagated in the medium. Since wheel-…

Rayonnement des ondes ultrasonores guidées dans une structure mince et finie, métallique ou composite, en vue de son contrôle non-destructif, Guided wave radiation in a finite-sized metallic or composite plate-like structure for its non-destructive testing

Mathilde Stévenin

Différents modèles sont développés de façon à constituer des outils génériques pour la simulation de méthodes de contrôle non-destructif par ondes élastiques guidées de plaques métalliques ou composites. Diverses méthodes de contrôle de ces structures existent ou sont à l’étude. La plupart font…, Different models are developed to provide generic tools for simulating nondestructive methods relying on elastic guided waves applied to metallic or composite plates. Various inspection methods of these structures exist or are under study. Most of them make use of ultrasonic sources of finite size…

Real-time mechanical characterization of DNA degradation under therapeutic X-rays and its theoretical modeling

Grégoire Perret, Thomas Lacornerie, Fabio Manca, Stefano Giordano, Momoko Kumemura, Nicolas Lafitte, Laurent Jalabert, Mehmet C Tarhan, Eric F Lartigau, Fabrizio Cleri, Hiroyuki Fujita, Dominique Collard

Abstract The killing of tumor cells by ionizing radiation beams in cancer radiotherapy is currently based on a rather empirical understanding of the basic mechanisms and effectiveness of DNA damage by radiation. By contrast, the mechanical behaviour of DNA encompassing sequence sensitivity and…

On the ability of molecular dynamics simulation and continuum electrostatics to treat interfacial water molecules in protein-protein complexes

Guillaume Copie, Fabrizio Cleri, Ralf Blossey, Marc Lensink

Interfacial waters are increasingly appreciated as playing a key role in protein-protein interactions. We report on a study of the prediction of interfacial water positions by both Molecular Dynamics and explicit solvent-continuum electrostatics based on the Dipolar Poisson-Boltzmann Langevin (DPBL…

Activity of enzymes immobilized on plasma treated polyester

Arfaoui Mohamed, Behary Nemeshwaree, Mutel Brigitte, Perwuelz Anne, Belhacene Kalim, Pascal Dhulster, Anne-Sophie Mamede, Rénato Froidevaux

The aim of this study was to investigate the effect of 3 different surface plasma treatments on the immobilization of β-galactosidase on a fibrous PET nonwoven membrane. Two methods 1. Entrapment in a thin calcium alginate coating and 2. Direct sorption, were used to immobilize the enzyme. The…
