Experimental Study of the Evolution of Temperatures in Pavement Structures and Influence of Traffic on the RN1 in Burkina Faso in a Hot and Dry Climate
Paul Ilboudo, Boubacar Soro, Dieudonné Dabilgou, Boureima Kaboré, Jean Marie Compaoré, Sié Kam, Dieudonné Joseph Bathiebo
Asphalt concrete pavements in hot and dry climates deteriorate prematurely some time after their construction. This degradation is accelerated under the effect of heavy vehicle traffic pressure and high temperatures after the bitumen has softened. A study was conducted on the RN1 in Burkina Faso in order to analyze the evolution of temperatu(...)

Study of the Thermodynamic Properties of Thermal Plasmas of Fluoroalkylamine-Air Mixtures
Pafadnam Ibrahim1, Kohio Nièssan1, Yaguibou Wêpari Charles1, Kagoné Abdoul Karim1, Koalaga Zacharie1, André Pascal2
Knowledge of thermodynamic properties as well as parameters such as energy density and power flow is important for modeling thermal plasmas of fluoroalkylamine- air mixtures. In this paper, these thermodynamic properties of fluoroalkylamine-air mixture plasmas are calculated in a temperature range of 500 K to 20,000 K at atmospheric pressure a(...)

COMPARATIVE STUDY OF THE EFFECTS OF SIMULATION MODELS ON THE ELECTRONIC AND ELECTRICAL PARAMETERS OF A SILICON PV CELL
KPÉLI ESSO-EHANAM TCHEDRE, MAHAMADI SAVADOGO, GUY SERGE TCHOUADEP, ISSA ZERBO AND MARTIAL ZOUNGRANA
For silicon solar cells simulation studies, one dimensional (1D), two dimensional 2D) and t
hree dimensional (3D) models are used. Depending of model proposed and assumptions done for the study,
the electronic and electrical parameters and then the performance of the solar cell can be influenced.
This situation raises the problem of the rel(...)

Thermomechanical and Hydrous Effect of Heavy Fuel Oil in a Building Material Based on Silty Clayey Soil
Ohindemi G. Yameogo, Donzala D. Some, Sié Kam, Adamah Messan, Takenori Hino, Dieudonné J. Bathiebo
This study focuses on the use of heavy fuel oil in construction in Burkina Faso. Mixed with silty and/or clay soil, it is used as a coating to reinforce the walls of raw soil constructions which are very sensitive to water. The interest of this paper is to shed light on the thermomechanical and above all water effects of heavy fuel oil on a sa(...)

Development and characterization of thermal insulation panels based on rice husks and kapok fibers stabilized with plaster
Ouedraogo Ousmane, Compaore Abdoulay, Namoano David, Igo Wendsida Serge, Dissa Alfa Oumar
This study is part of the recovery of agricultural residues and plant fibers in the thermal insulation of buildings. Set plaster is commonly used in construction as a thermal insulation for roofs or walls (in the form of panels or coating). The study analyzed the influence of the incorporation of rice husk and kapok wool on the thermal and mec(...)
