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 ZougmoréThe 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...

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. NacoulmaPlant 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...

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. MaazaIn 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...

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. Sissokohe 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...

Adsorptive removal of α-endosulfan from water by hydrophobic zeolites. An isothermal study
Arsène H. Yonli, Isabelle Batonneau-Gener, Jean KoulidiatiThis 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...

The BIOTA Biodiversity Observatories in Africa—a standardized framework for large-scale environmental monitoring
A. THIOMBIANOThe 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...

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 MogensThe 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...

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 JakobsenMaari 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...

PAPR Distribution Analysis at the Output of Nonlinear PAPR Reducers
Désiré GUEL, Jacques PALICOTNonlinear 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...

The multiplicative anomaly for determinants revisited; locality
Marie Françoise Ouedraogo, Sylvie PaychaObserving 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...
