Sidpouita Mathilde Koudougou1,2*, Guy Christian Tubreoumya2,3, David Yemboini Kader Toguyeni1,2, Tégawendé Justin Zaida1
Current pavement design methods do not allow for the reduction of early
deformation of the surface layers of bituminous pavements in the city of
Ouagadougou. Weather conditions combined with traffic, particularly during
heat waves, are factors. The temperature at the surface of the bituminous
pavement can reach 62˚C but the complex mod(...)

Equilibrium Composition of a Plasma in the Low Voltage Air Circuit Breaker Contaminated by the Vapor of AgSnO 2 Alloy Electrical Contacts
Banouga Adjigkiga, Kagoné Abdoul Karim, Yaguibou Wêpari Charles, Kohio Niéssan, Koalaga Zacharie, Zougmoré François
When the circuit breaker cuts the electric current, an electric arc is created
between its electrodes. The success or failure of breaking the electric current
by the circuit breaker depends strongly on the physico-chemical properties of
the electric arc created, such as the composition of which depends on the
material of the electrical con(...)

Modelling the Influence of Low Energy Electrons Emitted from Pm-147 on the Performance of a Silicon PV Cell
G. S. Tchouadep, E. K. Tchédré, I. Sourabié, I. Zerbo, and Martial Zoungrana
This paper investigated, using 1-D analysis, the effect of low energy electrons emitted from Promethium – 147 (Pm-147) on the performance of a silicon PV cell. The Pm-147 source is chosen due to the penetration depth of beta particles with the average kinetic energy of 62.5 KeV emitted from Pm-147, because at this depth the are able to generat(...)
