Mercury, arsenic and selenium concentrations in water and fish from sub-Saharan semi-arid freshwater reservoirs (Burkina Faso)
Ousséni Ouédraogo, Marc Amyot
Despite 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 arsenic (As) contamination in aquatic
systems and t(...)

To what extent do protected areas determine the conservation of native flora? A case study in the Sudanian zone of Burkina Faso
A. OUEDRAOGO
Natural 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 creation of protected forests, have been taken to safe(...)

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. DICKO
Thirty 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. Total phenols were measured using the Folin-Ciocalteu(...)

L'introuvable articulation transport-urbanisme ou la face cachée de la décentralisation à Ouagadougou
KIETTYETTA Jean Yves
La gestion urbaine en vigueur à Ouagadougou est exercée sur fond de décentralisation. Le Code général des collectivités locales établit une répartition des compétences entre l'Etat et les collectivités locales et préconise que cette répartition soit régie par les principes de subsidiarité, de progressivité et de proximité. Onze prérogatives le(...)

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 fluorescence,
inductively coupled plasma (ICP), X-ray photoe(...)

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. Sissoko
The 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 quality and conversion efficiency.

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. SISSOKO
In 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 Gauss’s Law helped us to calculate the width emitte(...)

Ethnobotanical knowledge and valuation of woody plants species: a comparative analysis of three ethnic groups from the sub-Sahel of Burkina Faso
A. THIOMBIANO
Local 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 valuation of woody plant species in three ethnic(...)

Support vector machines for anti-pattern detection
Abdou Maiga, Nasir Ali, Neelesh Bhattacharya, Aminata Saban_e, Yann-Gael Gu_eh_eneuc, Giuliano Antoniol, Esma A_meur
Developers may introduce anti-patterns in their software systems because of time pressure, lack of understanding, communication, and--or skills. Anti-patterns impede development and maintenance activities by making the source code more difficult to understand. Detecting anti-patterns in a whole software system may be infeasible because of the(...)
