Reperfusion injury is caused by the rapid restoration of blood flow to oxygen-starved tissue. Animal studies show that intermittent periods of occlusion (also called post-conditioning) during reperfusion can limit tissue damage to vital organs such as the heart and brain. These studies ...

We discuss the implementation of artificial boundary conditions for stationary Navier-Stokes flows past bodies in the half-plane, for a range of low Reynolds numbers. When truncating the half-plane to a finite domain for numerical purposes, artificial boundaries appear. We present an ... En savoir plus

Superparamagnetic micro beads offer some  attractive applications in biological and biomedical fields. Some of the important applications include manipulation and separation of cells, isolation of specific cells, active drug delivery, magnetic cell separation, separation of proteins, and ...

For the purpose of investigation the inertial behaviour of the crystalline lens, the COMSOL Multiphysics® software was used to create a 2D multi-physics model of the porcine eye globe, by using the Fluid-Structure Interaction (FSI). The geometry of the porcine eye model was adapted from ... En savoir plus

In recent years, Atomic Force Microscopy (AFM) has played a key role in the characterisation of surface structures and materials at the microscopic level. One of the most important aspects of AFM image analysis is the reliable provision of pore size and cross-linking rate data. AFM uses ... En savoir plus

During the hot extrusion process, a cylindrical pre-heated billet is inserted into a container and is forced by a hydraulic press to flow through a shaped die in order to obtain, as final product, a profile with a constant cross-section (Fig.1). Aluminum extrudates have become prominent ... En savoir plus

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

The EPFLoop team from Lausanne last year won the 3rd place in SpaceX’s Hyperloop Pod Competition in 2018. This year the team will participate at the 2019 Competition held at the SpaceX facilities California. Reliability of the different subsystems constituting the pod is a key point. ... En savoir plus

Deformation prediction is an important part of the structure stability analysis. However, the deformation of bank protection structure which is affected by many factors, such as structural stiffness, earth pressure and hydrostatic pressure. It contains a complex mechanical process, which ... En savoir plus

The vestibular systems are very important to balance of body. But some people have vertigo and dizziness caused by vestibular disorder. It is well known how the symptom appears physiologically. The benign paroxysmal positional vertigo (BPPV) which comes from moving an otolith in ... En savoir plus
