The intestine, a muscular, tubular organ within the digestive system is responsible for the final stages of food processing. The cyclic material transport generates a shear stress on the intestinal lining known as epithelium. Recently, the application of shear stress on epithelial cells ... En savoir plus

Macroscopic modeling of fluid flow and thermal diffusion, in a porous medium, requires the description of equivalent properties (permeability, conductivity and diffusivity). However, depending on the microstructure topology of the porous medium and the fluid flow regime at the ... En savoir plus

In the field of industrial marking, continuous inkjet technology is based on high speed emission of ink drops. The printing quality is directly linked to the interactions of the droplets with their environment during flight time : electric field, aerodynamic perturbations, and droplet ... En savoir plus

Porous guided bone regeneration (GBR) meshes are used in dentistry as a mechanical barrier to separate and protect the area of bone loss, providing space for new bone growth. An appropriate pore size can play a role, as important as its space-maintaining properties. The characteristics ... En savoir plus

Nondestructive inspection (NDI) of damages (e.g., imperfect or degraded bonding lines) or the remaining strength of adhesively bonded lap joints is critical for the operational safety of aircrafts and vehicles. It remains a challenge to use the conventional NDI to quantitatively infer ... En savoir plus

For reheating steel slabs in the steel industry fossil energy like natural gas or oil-based fuels is commonly used. Induction heating is one possible way on the transition towards a carbon free steel industry. To support the industries ambition to change from furnaces with fossil energy ... En savoir plus

Micro-lenses with potential applications in optics on the surface of the various heavy-metal oxide glasses were created and studied experimentally [1-2]. Laser direct writing using continuous-wave laser emitting at 447 nm was successfully performed [2]. The aim of this study is to ... En savoir plus

Microfluidics and Biosensors are two principal fields that paved the way for the inception of Lab-on-a-chip (LOC) which provides early and cost-effective disease detection, from monitoring to treatment. LOC is a device that uses very small amounts of fluid on a microchip to do certain ... En savoir plus

This communication describes a model created to investigate the effect of mold-metal contact on casting solidification in the continuous casting process. The Heat Transfer and Solid Mechanics modules of COMSOL Multiphysics® simulation software are used to construct a non-linear finite ... En savoir plus

The current general context for green production and decarbonation prompts considering alternative solutions to produce high added value byproducts from gas decomposition without producing CO2. Steam Reforming or Combustion processes, widely applied in Industry, need H2O or O2 to ... En savoir plus
