Acacia communities and species responses to soil and climate gradients in the Sudano-Sahelian zone of West Africa
S. TRAOREAbiotic environmental factors have a major impact on the distribution and performance of plant species. In order to assess two major species–environmental relations in Sudano-Sahelian Acacia woodlands, we tested the relationship of soil and climate variables on plant diversity as well as on...

Evidence for population-specific positive selection on immune genes of Anopheles gambiae
A. GNEMEHost-pathogen interactions can be powerful drivers of adaptive evolution, shaping the patterns of molecular variation at the genes involved. In this study, we sequenced alleles from 28 immune-related loci in wild samples of multiple genetic subpopulations of the African malaria mosquito...

Elliptic problem involving diffuse measure data
Noureddine Igbida, Stanislas Ouaro and Safimba SomaIn this paper, we study a suitable notion of solution for which a nonlinear elliptic problem governed by a general Leray–Lions operator is well posed for any diffuse measure data. In terms of the paper (Brezis et al., 2007, [10]), we study the notion of solution for which any diffuse measure...

Mercury, arsenic and selenium concentrations in water and fish from sub-Saharan semi-arid freshwater reservoirs (Burkina Faso)
Ousséni Ouédraogo, Marc AmyotDespite intensive mining activities in Burkina Faso, little is known on the environmental impacts of metals and
metalloids potentially released from these activities. Water samples and 334 fish from 10 reservoirs were
taken in order to evaluate the extent of mercury (Hg), selenium (Se) and...

In vitro Inhibition of Acetyl Cholinesterase, Lipoxygenase, Xanthine Oxidase and Antibacterial Activities of Five Indigofera (Fabaceae) Aqueous Acetone Extracts fro...
20. Bakasso S., A. Lamien-meda, C.E. Lamien, M. Kiendrebeogo, A.Y. Coulibaly, M. Compaoré, N.R. Meda and O.G. NacoulmaThe aim of this study is to evaluate the inhibition of oxidative stress related enzymes of aqueous acetone
extracts, as well as antibacterial activity from five Indigofera species well-known medicinal plant from Burkina.
Also are investigated in this study the potential contribution of tannins...

To what extent do protected areas determine the conservation of native flora? A case study in the Sudanian zone of Burkina Faso
A. OUEDRAOGONatural vegetation contributes significantly to the daily needs of local people especially in the developing countries. This exerts a high pressure on freely accessible natural savannas and jeopardizes the conservation of protected areas. In Burkina Faso, conservation measures, such as the...

Comparison of phenolic compounds and antioxidant capacities of traditional sorghum beers with other alcoholic beverages
ABDOUL-LATIF Fatouma, Romaric G. BAYILI, Louis C. OBAME, Imael H.N. BASSOLE, and Mamoudou H. DICKOThirty samples of sorghum beers “dolo” were selected from traditionally fermented household manufacturers from Burkina Faso. Dolo samples were screened for their total phenolic content, proanthocyanidins and putative antioxidant capacities, and were compared with industrial beers and wines....

Growth and characterization of large, high quality MoSe2 single crystals
Moussa Bougouma ,Abdelkrim Batan , Boubie´ Guel , Tiriana Segato , Jean B. Legma , Francois Reniers , Marie-Paule Delplancke-Ogletree , Claudine Buess-Herman , Thomas Doneux ,MoSe2 single crystals were grown by chemical vapor transport using TeCl4 as transport agents in the
temperature gradient 1020–980 1C. They were characterized by scanning electron microscopy (SEM),
optical microscopy, image analysis coupled with SEM, microanalysis by SEM-EDX, X-ray...

Ethnobotanical knowledge and valuation of woody plants species: a comparative analysis of three ethnic groups from the sub-Sahel of Burkina Faso
A. THIOMBIANOLocal people's perceptions of plant species are an important source of information on species distribution and rarity, as well as long-term vegetation change. This study involves an ethnobotanical survey and the identification of potential factors that explain differences in the perceptions and...

DETERMINATION IN 3D MODELLING STUDY OF THE WIDTH EMITTER EXTENSION REGION OF THE SOLAR CELL OPERATING IN OPEN CIRCUIT CONDITION BY THE GAUSS’S LAW
E. SOW, S. MBODJI, B. Zouma, M. Zoungrana, I. Zerbo, A. Sere and G. SISSOKOIn this article, we are discussing the Gauss’s law used to determine the width emitter extension region of the solar cell operating in open circuit condition. Taking into account the grain size (g), the grain boundary recombination velocity (Sgb) and the emitter doping density (Nemitter), the...

SILICON SOLAR CELL UNDER ELECTROMAGNETIC WAVES IN STEADY STATE: ELECTRICAL PARAMETERS DETERMINATION USING THE I-V AND P-V CHARACTERISTICS
O. SOW, I. ZERBO, S. Mbodji; M. I. NGOM; M. S. DIOUF and G. SissokoThe principal effect that limits solar cell efficiency is the recombination of the photo generated charge carriers before they participate to energy current. These recombination are characterized by electronic (recombination) and electric interdependent parameters that influence the solar cell...
