Weak homoclinic solutions of anisotropic difference equation with variable exponents.
A. Guiro, B. Koné, S. Ouaro
In this paper, we prove the existence of homoclinic solutions for a family of anisotropic difference equations. The proof of the main result is based on a minimization method and a discrete Hölder type inequality

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(...)

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(...)

Antimicrobial activities of essential oil and methanol extract of Boswellia sacra Flueck. and Boswellia papyrifera (Del.) Hochst from Djibouti
ABDOUL-LATIF Fatouma Mohamed, Louis-Clément Obame, Imael H. N. Bassolé and Mamoudou H. DICKO
Boswellia sacra and Boswellia papyrifera belong to the family of Burseraceae. The daily and ritual use of Boswellia is characteristic cultural of the horn of Africa which transcends the ethical and religious memberships. Plants samples of Boswellia sacra and Boswellia papyrifera were collected in Djibouti. The essential oil and methanol extrac(...)

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(...)

Regeneration pattern of four threatened tree species in Sudanian savannas of Burkina Faso
A. THIOMBIANO
Research was carried out on four threatened tree species across north and south Sudanian phytogeographical zones in Burkina Faso. A quantitative inventory of regeneration populations was completed and sapling dynamics were monitored through surveys of survival and growth in permanent plots. Laboratory and nursery experiments were carried out t(...)

Characterization of carbonaceous and nitrogenous species during the reductive and oxidative combustion of biomass : Case of millet stalks
Salifou Koucka Ouiminga, Thomas Rogaume, Arsène H. Yonli, Alfa Oumar Dissa, Jean Koulidiati
Millet stalks are used as fuel in pottering crafting in Africa. A study was conducted to characterize the gaseous species produced during the reductive and oxidative combustion of millet stalks. The experiment was carried out on temperature ranging from 800-1000°C, using the tubular furnace, coupled with two gas analyzers i.e. Analyzer Fourier(...)
