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(...)

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(...)

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(...)

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(...)

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(...)

As part of ongoing research on the chemical composition and the antimicrobial properties of Burkinabe
plants essential oils alone and in combination, essential oils (EOs) from leaves of Cymbopogon citratus and
Cymbopogon giganteus from Burkina Faso were analyzed by GC–FID and GC–MS. Five constituents, which
accounted for 96.3% of the oil, w(...)

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(...)

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(...)
