High performance amylolytic yeast strains isolation and identification for valorization of potatoes waste available in Burkina Faso
Ouédraogo N., Savadogo A., Zongo C., Somda K. M. and Traoré A. S.
This study deals with isolation and identification of high amylolytic activity strains from potato wastes for biomass production. A total of twenty five (25) yeast strains were isolated using standard microbiological methods. Ten (10) strains were retained on the basis of their capacity to hydrolyze starch. Identification to species level of s(...)

Classification of traces and associated determinants on odd-class operators in odd dimensions
Carolina Neira Jiménez, Marie Françoise Ouedraogo
To supplement the already known classification of traces on classical pseu-dodifferential operators, we present a classification of traces on the algebras of odd-class pseudodifferential operators of non-positive order acting on smooth functions on a closed odd-dimensional manifold. By means of the one to one correspondence between continuous(...)

Essential Oils in Combination and Their Antimicrobial Properties
Imaël Henri Nestor Bassolé , * and H. Rodolfo Juliani
Essential oils (EOs) have been long recognized for their antibacterial, antifungal, antiviral, insecticidal and antioxidant properties. They are widely used in medicine and the food industry for these purposes. The increased interest in alternative natural substances is driving the research community to(...)

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(...)

Carotenoids content and antibacterial activity from galls of Guiera senegalensis JF Gmel (combretaceae).
Sombie Pierre Alexandre Eric Djifaby, Coulibaly Ahmed Yacouba,Hilou Adama,Konate Kiessoum, Compaore Moussa Marie-Hyacinthe, Nacoulma Odile Germaine
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/(...)

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(...)

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(...)

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(...)
