ESTIMATING HEAT AND MASS QUANTITIES TRANSFERED BETWEEN FREE SURFACE WATER AND THE ATMOSPHERE USING THE ENERGY BALANCE METHOD.
P. Florent KIENO and Alfred BAYALA.
We hereby present a study on heat and mass transfer between free surface water and the atmosphere in Burkina Faso. We preferentially chose the city of Ouagadougou to conduct this study. One of the major problems in studying evaporation is how to determine water surface temperature and the flow of water evaporated. We calculated this surface te(...)

Thermodynamic Quasi-Equilibrium Model for the Energetic Performances Analysis of the Air and Air–Steam Gasification of Raw and Pretreated Cotton Stalks by Torrefaction and Carbonization
Harouna Gado Ibrahim, Oumar Sanogo, Tizane Daho, Salifou K. Ouiminga, Jean Koulidiati
Numerical and experimental study of the gasification of raw and pretreated (torrefied and carbonized) cotton stalks were investigated. The experimental results were used to calibrate the quasi-equilibrium model by multiplying the equilibrium reaction constant with coefficient varying from 0.01 to 10 and by fixing the methane molar fraction.

A theoretical study of radio wave attenuation through a polycrystalline silicon solar cell
Adama OUEDRAOGO, Vinci de Dieu Bokoyo BARANDJA1, Issa ZERBO, Martial ZOUNGRANA, Emmanuel Wendsongré RAMDE, Dieudonné Joseph BATHIEBO
One-dimensional study of both electronic and electrical parameters of a silicon solar cell in the presence or not of an electric eld, a magnetic eld, or an electromagnetic eld does not take into account the grain size and the grain boundary recombination velocity. A three-dimensional study, on the contrary, takes those factors into account.(...)

3-D Modeling of Temperature Effect on a Polycrystalline Silicon Solar Cell under Intense Light Illumination
Boubacar Soro, Martial Zoungrana, Issa Zerbo, Mahamadi Savadogo, Dieudonné Joseph Bathiebo
The efficiency of a silicon solar cell is directly linked to the quantity of carrier photogenerated in its base. It increases with the increase of the quantity of carrier in the base of the solar cell. The carrier density in the base of the solar
cell increases with the increase of the flux of photons that crosses the solar cell. One of the m(...)

Modelling Study of Magnetic Field Effect on the Performance of a Silicon Photovoltaic Module
Dioari Ulrich Combari1, Issa Zerbo, Martial Zoungrana, Emmanuel Wendsongre Ramde, Dieudonné Joseph Bathiebo
Solar Photovoltaic is a very promising solution that can greatly contribute in solving the increasing global energy demand. In both rural and urban areas, photovoltaic modules are in some instances installed close to telecommunication antennas or voltage transformers which generate important magnetic fields in their vicinity. The question is w(...)

Evaluation of global solar radiation from meteorological data in the Sahelian zone of Chad
Marcel Hamda Soulouknga, Ousmane Coulibaly, Serge Yamigno Doka and Timoleon Crepin Kofane
The study focuses on the evaluation of global solar radiation on a horizontal level. The estimate of the solar layer was
made on the basis of mathematical model obtained from the relations of Angstrom–Prescott, Allen and Sabbagh.
The different proposed models have been implemented by using MATLAB and Excel. The models were evaluated
using M(...)

H i kinematics and mass distribution of Messier 33
S Zacharie Kam, Claude Carignan, Laurent Chemin, Tyler Foster, Ed Elson, Tom H Jarrett
A new deep H i survey of the galaxy Messier 33 is presented, based on observations obtained at the Dominion Radio Astrophysical Observatory. We observe a perturbed outer gas distribution and kinematics in M33, and confirm the disk warping as a significant twist of the major axis of the velocity field, although no strong tilt is measured, in ag(...)
