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(...)

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(...)

Existence and uniqueness of weak and entropy solutions for homogeneous Neumann boundary-value problems involving variable exponents
B.K. Bonzi, I. Nyanquini, S. Ouaro
We study the nonlinear homogeneous Neumann boundary-value problem
b(u)−diva(x,∇u)=fin Ωa(x,∇u).η=0on ∂Ω,
where Ω is a smooth bounded open domain in ℝN, N≥3 and η the outer unit normal vector on ∂Ω. We prove the existence and uniqueness of a weak solution for f∈L∞(Ω) and the existence and uniqueness of an entropy solution for L1-data f. The f(...)

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(...)

Formulation of oral pharmaceutical dosage forms containing crude extracts of Artemisia Annua
H. Zimé-Diawara, F. Gbaguidi, J. Gbenou, A. Laleye, R. Semde, I. Some, B. Sinsin, M. Moudachirou, J. Quetin-Leclercq, B. Evrard.
Artemisia annua is an asiatic plant with curative properties against malaria,
containing artemisinin. This active compound, and its derivatives are the last few
antimalarial drugs that remain effective against multidrug resistant strains of
Plasmodium falciparum. But they are very expensive and not accessible to poor
African countries.

Thermal Degradation of Polyethylene Bags and Millet Stalks: Influence of the Temperature and the Local Concentration of Oxygen on the Conversion Rate of Carbon.
Salifou K. Ouiminga, Thomas Rogaume, Tizane Daho, Franck Richard, Jean Koulidiati.
This paper concerns the influence of temperature and local concentration of oxygen on the conversion efficiency of carbon into CO, CO2, CH4, C3H8, C2H4, C2H2, C2H6, C6H6, during the thermal degradation of plastic bags and millet stalks. The experimental device used is the tubular kiln, coupled to an analyzer Fourier Transform Infrared (FTIR) a(...)

An engineered Plasmodium falciparum C-terminal 19-kilodalton merozoite surface protein 1 vaccine candidate induces high levels of interferon-gamma production associated with cellular immune responses to specific peptide sequences in Gambian adults naturally exposed to malaria
C Bisseye, L M Yindom, J Simporé, W D Morgan, A A Holder, J Ismaili
The 19-kDa C-terminal region of merozoite surface protein 1 (MSP1(19)), a major blood stage malaria vaccine candidate, is the target of cellular and humoral immune responses in humans naturally infected with Plasmodium falciparum. We have previously described engineered variants of this protein, designed to be better vaccine candidates, but th(...)

Risques de dégradation des ressources naturelles des aires protégée liés aux implantations humaines : le cas de Sambouali dans la province de la Kompienga
DIPAMA Jean-Marie
Les écosystèmes de l'Est du Burkina Faso sont en proie à une dégradation accentuée suite à l'ébranlement de certaines composantes engendré par des facteurs socio-économiques. Or, depuis longtemps, le souci de préserver le potentiel écologique et la diversité biologique avait motivé la délimitation d'aires protégées. Malheureusement, ces territ(...)
