Voies veineuses périphériques et risque d’infections acquises en réanimation

Plus de la moitié des patients hospitalisés sont porteurs d’un cathéter veineux, le plus souvent périphérique. Sa mise en place aisée et rapide permet l’administration des traitements et des solutés de remplis...

A Procedure for Accurate One-Dimensional Strain Measurement Using the Grid Method

This paper deals with the accurate calculation of strain using the grid method. The strain field is first directly deduced from the fringe pattern without calculating the displacement field. This procedure is ...

Endoprothèses peropératoires: Un plus? Pour quelle dissection?

La dissection aortique aiguë est une fracture longitudinale de la paroi de l’aorte. Le traitement vise à réduire et à fixer la lésion, cette «aorto-synthèse» va permettre une restauration ad integrum de l’anatomi...

Confined diffusion of hydrophilic probes inserted in lyotropic lamellar phases

The dynamic behaviour of three hydrophilic probes (two dyes and one fluorescently-labelled protein) inserted in the water layers of lyotropic lamellar phases has been studied by confocal fluorescence recovery ...

Specific Features of Nanoscale Growth

It is no easy matter to make nanoscopic objects. In fact, starting from a macroscopic sample, as one does when making objects with centimeter or millimeter dimensions, one soon comes up against technical probl...

Biology and the Environment

Since the 1980s, catalytic antipollution systems for petrol-fuelled vehicles have considerably reduced emissions of CO, NO _x , and unburnt hydrocarbons. They use precious metals as c...

Role of dislocation loops on the elastic constants of lyotropic lamellar phases

We study the role of dislocation loops defects on the elasticity of lamellar phases by investigating the variation of the lamellar elastic constants, ¯ and K, induced by the proliferation of these defects. We foc...

The Gibbs Phenomenon for n-Dimensional Kernels

We give conditions which ensure the existence in R ⁿ of the Gibbs phenomenon for a large class of kernels non necessarily rotation or translation invariant.

Dynamical rheology of a lyotropic lamellar phase near an out-of-equilibrium transition

This work deals with sustained oscillations of a complex fluid near a shear-induced transition. Rheological measurements of the onion texture near a layering transition are performed in a Couette cell. This co...

Incorporating DNA in a lamellar phase: A Flory model

Following an experimental work demonstrating that DNA pieces can be incorporated in large quantity in a neutral lamellar phase, we propose a theoretical model showing that finite-size rod-like particles can be...

Anomalous elasticity of an ordered lamellar liquid foam

We investigate experimentally the linear viscoelastic properties of a lamellar liquid foam as a function of the cell size and spatial organisation. The system consists of multilamellar vesicles generated by a ...

Swelling kinetics of a compressed lamellar phase

We investigate how multilamellar vesicles prepared in a compressed state under flow return to equilibrium. The kinetics is studied by following the temporal evolution of the viscoelasticity after the shear is ...

Lamellar-to-nematic phase transition in a lipid-surfactant mixture

A lyotropic system, consisting of a lecithin (DMPC) and a non-ionic surfactant (C₁₂E₅) in water was studied. The system exhibits a lamellar-to-nematic phase transition. The nematic phase appears as the temperatur...

Undulation instability under shear: A model to explain the different orientations of a lamellar phase under shear?

We study the effects of a dilation on a sheared smectic A phase. Through a linear analysis, we show that undulation may grow in the direction of the flow and of the vorticity as found in previous works. At hig...
