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(...)

In vitro Antioxidant and Anti‐inflammatory Activities of Extracts from Nicotiana tabacum L. (Solanaceae) Leafy Galls Induced by Rhodococcus fascians
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(...)

Analysis of the Diffusion Capacitance’s Efficiency of the Bifacial Silicon Solar Cell in Steady State Operating Condition
S. Mbodji, B. Mbow, I. Zerbo and G. Sissoko
he aim of this study is to study the diffusion capacitance’s efficiency of the n+ -p-p + bifacial solar cell. The dependence of the efficiency of the diffusion capacitance on both the excess minority collection region in open circuit and short-circuit operating points of the solar cell has been itemised for varying grain size (g), grain bounda(...)

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(...)

Adsorptive removal of α-endosulfan from water by hydrophobic zeolites. An isothermal study
Arsène H. Yonli, Isabelle Batonneau-Gener, Jean Koulidiati
This paper deals with the removal of α-endosulfan from water over HY and steamed HBEA zeolites. Experiments were performed to understand the adsorption mechanisms of α-endosulfan on zeolites and to determine the most efficient adsorbent for the purification of water contaminated by this pesticide. The experiments exhibit that α-endosulfan was(...)

The BIOTA Biodiversity Observatories in Africa—a standardized framework for large-scale environmental monitoring
A. THIOMBIANO
The international, interdisciplinary biodiversity research project BIOTA AFRICA initiated a standardized biodiversity monitoring network along climatic gradients across the African continent. Due to an identified lack of adequate monitoring designs, BIOTA AFRICA developed and implemented the standardized BIOTA Biodiversity Observatories, that(...)

Bacteriocin formation by dominant aerobic sporeformers isolated from traditional maari
117. KABORÉ Donatien, Thorsen, Line, Nielsen, Dennis Sandris, Berner, Torben Sune, Sawadogo-Lingani, Hagr´etou, Diawara, Br´ehima, Mamoudou H. DICKO, Jakobsen Mogens
The antimicrobial activity of 8 Bacillus spp. and 2 Lysinibacillus spp. representing the predominant aerobic sporeformers during traditional maari fermentations, a traditional fermented baobab seeds product fromBurkina Faso,was investigated. The antimicrobial activitywas assessed against a total of 31 indicator organisms representing various G(...)

Improvement Of The Hygienic Quality Of Farmhouse Meat Pies Produced In Burkina Faso
ILBOUDO A.Jules, TAPSOBA François, SAVADOGO Aly, SEYDI Mg and TRAORE Alfred.S
The objective of the present study was to improve the hygienic quality of farmhouse meat pies produced in
Burkina Faso. This study revealed that only 6.25 % of the employees have knowledge as regards hygiene and
the enumeration of the aerobic flora total, of Staphylococcus, sulfite-reducing anaerobic bacteria, total coliforms
and of the(...)

Acid resistance, bile tolerance and antimicrobial properties of dominant lactic acid bacteria isolated from traditional “maari” baobab seeds fermented condiment
KABORÉ Donatien, Hagrétou Sawadogo-Lingani1, Mamoudou H. DICKO, Bréhima Diawara and Mogens Jakobsen
Maari is a fermented food condiment obtained by spontaneous fermentation of seeds from the baobab tree (Adansonia digitata). Nine dominant lactic acid bacteria (LAB) strains, isolated from traditional maari fermentation were examined for their resistance to pH 2.5, their tolerance to 0.3% bile and their antimicrobial activities against pathoge(...)

The multiplicative anomaly for determinants revisited; locality
Marie Françoise Ouedraogo, Sylvie Paycha
Observing that the logarithm of a product of two elliptic operators differs from the sum of the logarithms by a finite sum of operator brackets, we infer that regularised traces of this difference are local as finite sums of noncommutative residues. From an explicit local formula for such regularised traces, we derive an explicit local formula(...)

PAPR Distribution Analysis at the Output of Nonlinear PAPR Reducers
Désiré GUEL, Jacques PALICOT
Nonlinear PAPR reducers, such as clipping and companding techniques, are some simple methods used to reduce the Peak-to-Average Power Ratio (PAPR). In this paper, assuming that the baseband OFDM signal is characterized as a band-limited complex Gaussian process, we investigate the PAPR distribution of an OFDM signal when it is passed through a(...)

Analyse des stratégies des pratiques agricoles face aux changements climatiques dans la Kompienga (Burkina Faso) et le Mekrou (Bénin)
DIPAMA Jean-Marie, VISSIN Expédit Wilfrid, HEDIBLE Sidonie, BOKO Michel
Le Burkina Faso et le Bénin présentent une situation socio-économique assez similaire : une population à majorité rurale qui s’adonne essentiellement aux activités agro-pastorales. Depuis quelques décennies, cette population est en forte croissance ce qui induit une exploitation effrénée des ressources dans un contexte de crises environnementa(...)
