Use of the corrected plane wave model for the determination of the reflection coefficient during horizontal plate swell interaction [PDF]

open access: yesMATEC Web of Conferences, 2019
The main objective of this work, is to calculate variations of the reflection coefficient of the regular wave by a submerged horizontal plate, using the corrected plane wave model, by choosing appropriately the immersion and the relative length of the ...

Evolution of polymer blend morphologies during extrusion in a flat die [PDF]

open access: yes, 2009
The control of blend morphologies during process is of prime importance in order to predict the final properties of polymer blends. A coextrusion technique combined with static mixers was developed in order to smartly blend polymeric melts and to ...

Vectorisation intra-oculaire [Drug delivery to target the posterior segment of the eye]. [PDF]

open access: yes, 2004
Retinal diseases are nowadays the most common causes of vision threatening in developed countries. Therapeutic advances in this field are hindered by the difficulty to deliver drugs to the posterior segment of the eye.

Reciprocal control of viral infection and phosphoinositide dynamics

open access: yesFEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.
