Hermine Zime-Diawara • Georges Dive • Géraldine Piel • Mansourou Moudachirou • Michel Frederich • Joëlle Quetin-Leclercq • Brigitte Evrard
Artemisinin extracted from Artemisia annua L.
proved to be currently, with its derivatives, the most effective
drugs against simple and severe malaria, and is also effective
on the chloroquine-resistant forms. The advantageous effect
of some cyclodextrins (CDs) on artemisinin solubilization
was demonstrated by different authors. The prese(...)

3D modelling of magnetic field and light concentration effects on a bifacial silicon solar cell illuminated by its rear side
M Zoungrana, I Zerbo, F Ouédraogo, B Zouma, F Zougmoré
According to their installation places, the solar cells are often under the effect of the electro-magnetic field coming from outside sources as telecommunication antennas, radio antennas... These magnetic fields have a big influence on the distribution and mobility of charge carriers in the base of the solar cell and therefore on its efficienc(...)

Silicon solar cell under electromagnetic wave in steady state: effect of the telecommunication source's power of radiation
I Zerbo, M Zoungrana, A D Seré, F Zougmoré
The characterisation of minority carriers’ recombination parameters is important to design any optoelectronic component, since they play an important role in the device performance. Many diagnostic techniques, steady state, quasi-steady state, transient and modulation methods for both the experimental and theoretical measurement have been deve(...)

In vitro Antioxidant and Anti‐inflammatory Activities of Extracts from Nicotiana tabacum L. (Solanaceae) Leafy Galls Induced by Rhodococcus fascians
Aminata P. Nacoulma, Moussa Compaoré, Manuella de Lorenzi, Martin Kiendrebeogo and Odile G. Nacoulma
Plant galls are widely distributed, and their extracts are used in traditional medicine worldwide. Traditional remedies containing extracts of plant galls in China, India and some African countries have effective in the treatment of various pathologies. To open a new promising procedure for screening bioactive compounds from plant galls, stand(...)

Time-based investigation of the growth of VO2(B) micro- and nanostructures on vanadium by hydrothermal synthesis
B.T Sone R. Benoit S. Zongo R. Bucher, M. Maaza
In an autoclave partly-filled with water wherein a V metal strip is placed 70° to the horizontal we observed that VO2 nanorods and exfoliated microspheres were generally grown on the portion of the strip above the water surface while parallelepiped-like structures were generally grown on the portion below. XRD, HRTEM, showed that VO2 structure(...)

Analysis of the Diffusion Capacitance’s Efficiency of the Bifacial Silicon Solar Cell in Steady State Operating Condition
S. Mbodji, B. Mbow, I. Zerbo and G. Sissoko
he aim of this study is to study the diffusion capacitance’s efficiency of the n+ -p-p + bifacial solar cell. The dependence of the efficiency of the diffusion capacitance on both the excess minority collection region in open circuit and short-circuit operating points of the solar cell has been itemised for varying grain size (g), grain bounda(...)

Adsorptive removal of α-endosulfan from water by hydrophobic zeolites. An isothermal study
Arsène H. Yonli, Isabelle Batonneau-Gener, Jean Koulidiati
This paper deals with the removal of α-endosulfan from water over HY and steamed HBEA zeolites. Experiments were performed to understand the adsorption mechanisms of α-endosulfan on zeolites and to determine the most efficient adsorbent for the purification of water contaminated by this pesticide. The experiments exhibit that α-endosulfan was(...)

KABORÉ Donatien, Hagrétou Sawadogo-Lingani1, Mamoudou H. DICKO, Bréhima Diawara and Mogens Jakobsen
Maari is a fermented food condiment obtained by spontaneous fermentation of seeds from the baobab tree (Adansonia digitata). Nine dominant lactic acid bacteria (LAB) strains, isolated from traditional maari fermentation were examined for their resistance to pH 2.5, their tolerance to 0.3% bile and their antimicrobial activities against pathoge(...)
