Elaboration d’une année météorologique type de la ville de Ouagadougou pour l’étude des performances énergétiques des bâtiments
E. Ouedraogo , O. Coulibaly et A. Ouedraogo
Dans cette étude, nous utilisons deux (02) méthodes de génération pour élaborer cinq (05) années types de sorte à déterminer la plus performante ou représentative. Ces années sont générées en utilisant des données de la température de l’air, de l’humidité relative de l’air, de la vitesse du vent et du rayonnement solaire(...)

Model for predicting evaporation characteristics of vegetable oils droplets based on their fatty acid composition
T. Daho, G. Vaitilingom, O. Sanogo, S. K. Ouiminga, B.G. Segda, J. Valette, P. Higelin, J. Koulidiati
In this work, a model for predicting evaporation characteristics (constant of evaporation and evaporation time) of cottonseed oil and diesel fuel has been developed and validated experimentally in the temper- ature range of 684–917 K under atmospheric pressure. The experimental study is based on the fibre-suspended droplet evaporation techniqu(...)

Guiera senegalensis is a well known medicinal plant which is used as a drug in Burkina Faso. The purpose of the present study was to investigate the carotenoids content and antibacterial activity from galls of Guiera senegalensis. The hydroacetonic extract (HAE) exhibited the highest of β-carotene (4.67±0.25 mg/g) and lycopene (0.99±0.0735 mg/(...)

Arsenic levels in tube-wells water, food, residents' urine and the prevalence of skin lesions in Yatenga province, Burkina Faso
Issa T. Somé,1 Abdoul K. Sakira, Moustapha Ouédraogo, Theodore Z. Ouédraogo, Adama Traoré, Blaise Sondo and Pierre I. Guissou2
The aim of the present study was to evaluate the levels of arsenic in tube-well water, food and residents' urines samples in Yatenga province, Burkina Faso. The prevalence of skin lesions was evaluated as well. The study was cross-sectional in design. It was conducted during April 2009. Permanent residents of 20 villages were included in the s(...)

Phytochemistry and Biological Activities of Extracts from Two Combretaceae Found in Burkina Faso: Anogeissus Leiocarpus (DC) Guill. and Perr. And Combretum Gl...
SORE H., HILOU A., SOMBIE Pierre A. E. D., COMPAORE M., MEDA R., MILLOGO J. and NACOULMA O. G.
Many studies indicate that Combretaceae species are commonly used in Africa to treat various diseases. Nonetheless, no phytochemical and/or biological activity data are available from species found in Burkina Faso to secure their ethnomedicinal uses. In addition, drugs derived from these species, especially those of the genus Combretum, are so(...)

Separating competition-related factors limiting crop performance in an agroforestry parkland system in Burkina Faso
H. BAZIE
To address tree–soil–crop interactions in the Sahel, we examined the growth-limiting factors (water, light and mineral nutrients) of Sorghum bicolor growing under trees in agroforestry parklands of Burkina Faso. Growth and yields of sorghum were measured after (1) pruning crowns of Vitellaria paradoxa and Parkia biglobosa trees, and (2) applyi(...)

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(...)

3D determination of the minority carrier lifetime and the p-n junction recombination velocity of a polycrystalline silicon solar cell
R Sam, B Zouma, F Zougmoré, Z Koalaga, M Zoungrana and I Zerbo
This work presents a theoretical and experimental transient tri-dimensional study conducted for the determination of the bulk component of the minority carrier lifetime and the p-n junction recombination velocity of a bifacial polycrystalline silicon solar cell. The theoretical analysis is based on the columnar model of the grains in the polyc(...)

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(...)
