Utilisation des représentations spatiales en gestion intégrée des zones côtières

This article aims to study how mapping contributes to organize and implement Integrated Coastal Zone Management projects. In order to observe the use of spatial representations and better understand the stakeholder’s mapping practices a qualitative methodology is used. The results show that mapping was mostly used to structure and stabilize the actor’s network. MOTS-CLES : représentations spati...

Propriétés optiques non linéaires du 3e ordre des milieux organiques

2014 Optical nonlinear properties of semiconducting organic polymers with one dimensional 03C0 electron system are described. The third order nonlinear susceptibility of these polymers is specially high (#10-10 esu) and their time response very short (~ 1 ps ). Three and two photon resonances due to even and odd parity excited states are observed by third harmonic generation (THG) and by electr...
