Conception, Realization and Testing of a Solar Cooker Built with Ring Array Concentrator - RAC in sub Saharan region
Thierry Sikoudouin Maurice Ky, Ibrahim Sorgho, Sayoba Sawadogo, Dieudonne Dabilgou, Salifou Ouedraogo, Adama Ouedraogo, Sie Kam, Dieudonne Joseph Bathiebo
A Ring Array Concentrator - RAC was conceived, realized and tested for cooking purpose in Burkina Faso where irradiation flux is about 5.5kWh/m/day. The RAC, having a useful aperture area of 1.692 m, was built with five (5) imbricated conical concentrators. The conceived RAC has a mean geometric concentration ratio evaluated to 38, allowing a(...)

Search for Qualified Soil for the Production of Low-Energy Biobased Composite Materials
SANDWIDI Sayouba , HARO Kayaba , DABILGOU Téré , Sinon Souleymane , SANOGO Oumar , KOULIDIATI Jean, & BERE Antoine
The development of earth-based bio-sourced materials requires a thorough analysis of the study soil. For the present study, we took five (05) soil samples from a tunnel-digged quarry in the layer between 0.5 m and 5 m : white clay (MSB-BL), red clay (MSB-RG), weak clay or sandy clay (MSB-FB), strong clay (MSB-FR) and mixture (MSB-ME). To verif(...)

THOMAS SANKARA DANS LES PAYS GERMANOPHONES :LA PRATIQUE DU CONTRE-DISCOURS COMME DEMARCHE POLITIQUE
YAMEOGO, Mohamed
La réception de Thomas Sankara dans les pays germanophones témoigne de ce qu’il n’est plus l’héritage
de son seul pays, le Burkina Faso. Sa vie et l’impact de son oeuvre politique sous la révolution d’août
1983 interrogent et suscitent à la fois de l’admiration. En quatre années de gestion du pouvoir, il a su
trouver la formule pour tracer(...)

Higher diversity, denser stands and greater biomass in peri-urban forests than in adjacent agroforestry systems in Western Burkina Faso: implications for urban sustainability
Balima Larba Hubert, Zerbo Issouf, Bayen Philippe, Kiemtoré Henri, Ganamé Moussa, Cissé Mohamed & Thiombiano Adjima
Urban and peri-urban forests greatly contribute to the well-being of urban dwellers in West Africa. However, increasing urban densification and spatial expansion negatively affect the functioning of urban ecosystems. Therefore, highlighting the negative impacts of land use change on the ecological attributes of urban landscapes is fundamental(...)

MECANISMES D'INTEGRATION DES EMPRUNTS NOMINAUX DU KUSAAL
BAMBARA Houssouyam Appoline, KOHOUN Lamoussahan dite Sara
Notre communication porte sur les mécanismes d’intégration des emprunts nominaux du kusaal. Langue de type gur, elle est l’une des langues minoritaires parlée au sud-est du Burkina Faso, plus précisément à Zoaaga et à Youga. Le lexique d’une langue est un ensemble en constantes mutations. Son enrichissement passe, non seulement par la créatio(...)

Development of numerical model to describe water transfer in hygroscopic soil: use of a new method based on off-center upstream principle for convective flux
Samuel Ouoba, Alfa Omar Dissa and François Ouedraogo
This manuscript is focused on the mechanisms of water evaporation and the phenomena affecting its migration toward the groundwater. The objective is to estimate the essential parameters which govern the diffusion transfer. The phenomenological parameters used in the model are obtained experimentally and the mass transfer equations have been so(...)

Exponential stability for coupled Lameé system with a fractional derivative time Delay.
Noureddine Taouaf, Akram Ben Aissa et Gilbert Bayili
We develop a detailed analysis for a coupled Lamé system with fractional time delay. We show by using a semigroup approach and the well-known Dafermos auxiliary variable, that the system is well-posed. Moreover, we analyze stability issue for the considered system. Namely, under a suitable choice of Lyapunov functional, exponential decay of th(...)
