Optical and microphysical analysis of aerosols in Sahelian Zone: Case of the Ouagadougou City in Burkina Faso
Bado Nébon, Mamadou Simina Dramé, Korgo Bruno, Kieno P. Florent, Saidou Moustapha Sall and Bathiebo Dieudonné JosephThis paper analyzes aerosols in the Sahelian zone, particularly in Burkina Faso, based on in situ measurements of the AERONET network made from 1999 to 2006. Indeed, we characterize aerosols by studying their optical and microphysical parameters measured on the site of Ouagadougou (12.2° N,...

Potentials of an Eco-Friendly Composite in Hot-Dry Climate
Fati Zoma, David Y.K. Toguyeni, Ousmane Coulibaly, Ivon Hassel and Abdoulaye OuedraogoThis study aims to show the aptitude of a locally made composite for providing thermal comfort and mechanical resistance in buildings in hot-dry climates. The thermal characterization reveals that the thermal diffusivity of the studied material is lower than that of commonly used materials such...
