Identification of Catechin as One of the Flavonoids from Combretum albiflorum Bark Extract That Reduces the Production of Quorum-Sensing-Controlled Virulence Factors in Pseudomonas aeruginosa PAO1
Quorum-sensing (QS) regulates the production of key virulence factors in Pseudomonas aeruginosa and other
important pathogenic bacteria. In this report, extracts of leaves and bark of Combretum albiflorum (Tul.)
Jongkind (Combretaceae) were found to quench the production of QS-dependent factors in P. aeruginosa PAO1.

Isolation of a tannic acid-degrading Streptococcus sp. from an anaerobic shea cake digester
L.W. Nitiema, D. Dianou, J. Simporé, S.D. Karou, P.W. Savadogo, A.S. Traoré
An anaerobic digester fed with shea cake rich in tannins and phenolic compounds rich-shea cake and previously inoculated with anaerobic sludge from the pit of a slaughterhouse, enabled six months acclimatization of the bacteria to aromatic compounds. Afterwards, digester waste water samples were subject to successive culture on media with 1 g(...)

Les risques de dégradation des écosystèmes liés à la culture du coton au Burkina Faso: cas du parc national de Pô
DIPAMA Jean-Marie
Depuis 1995, la culture du coton connait une expansion considérable au Burkina Faso. Sa promotion vise à accroitre les revenus monétaires des paysans et lutter contre la pauvreté. L'engouement pour la culture du coton est à l'origine de l'envolée de la production du pays qui est passée de 147 000 à 600 000 tonnes entre 1996 et 2006. Cette dyna(...)

Diversité agromorphologique et commercialisation du gombo (Abelmoschus esculentus L.) à Ouagadougou et ses environs
Mahamadou SAWADOGO , Didier BALMA, Rasmata NANA et Rodrigue METO-KAZILE TUOSAN LIVIUS SUMDA
Au Burkina Faso, on a observé récemment à Ouagadougou et ses environs une mobilisation de petits producteurs pour la culture du gombo destinée à la population urbaine. La présente étude entreprise sur la base d’enquêtes réalisées dans quatre localités environnant la ville de Ouagadougou et dans onze de ses marchés a permis de comprendre que la(...)

Stratégie d’utilisation des substances naturelles dans la prise en charge des personnes vivant avec le VIH : expérience du Burkina Faso
J. B. Nikiéma, K. Djierro, J. Simporé et al.
Au Burkina Faso, les personnes vivant avec le VIH (PvVIH) ont régulièrement recours à des substances naturelles pour traiter certaines infections opportunistes. C’est ainsi que le suc des feuilles fraîches de Mitracarpus scaber Zucc. ex Schult. & Schult. f. (Rubiaceae) et de Senna alata (L.) Roxb. (Fabaceae) sont utilisés comme antimycosiques.(...)

Les grandes épisodes de sécheresse et leurs implications écologiques au Burkina Faso de 1970 à 2000
DIPAMA Jean-Marie
Depuis les années 1970, le Burkina Faso vit au rythme des sécheresses répétées. Cela s’est traduit par des déficits pluviométriques très importants. Cette étude réalisée à partir des enregistrements des principaux paramètres météorologiques des dix stations synoptiques du pays présente les traits généraux du phénomène de sécheresse à travers(...)

Generalisation of SBA (SOME Blaise-ABBO) algorithme for solving Cauchy nonlinear PDE (Partial Differential Equation) in n (n≥2) dimension space
PARE Youssouf, Francis BASSONO et Blaise SOME
In this paper, we propose a generalisation of the SOME Blaise-ABBO (SBA) method for the resolutionof some strongly non linearevolutive Cauchy partial differential equations (PDEs) in n (n≥2) dimension space like.

Linking participatory and GIS-based land use planning methods : A case study from Burkina Faso
HESSEL Rudi, BERG Jolanda van den, KABORE Oumar, KEKEMA Arie van, VERZANDVOORT Simone, DIPAMA Jean-Marie, DIALLO Binta
Sustainable land use planning is crucial for realizing the aim of food security and for combating land degradation in the Sahel. A participatory land use planning workshop was organised in a village in the eastern region of Burkina Faso to investigate land use problems, their causes, effects and possible solutions. Participatory research tool(...)

Performance comparison of PRC based PAPR reduction schemes for WiLAN Systems
Hussain Sajjad, Guel Désiré, Louët Yves, Palicot Jacques
High Peak to Average Power Ratio (PAPR) is a main area of concern in multi-carrier communications as in Orthogonal Frequency Division Multiplexing (OFDM) modulated transmission. Several techniques have been devised to reduce the PAPR of the OFDM signal. One of these PAPR reduction techniques is based on Peak Reducing Carriers (PRC) concept whe(...)

Finding out Egyptian Gods’ secret using analytical chemistry: biomedical properties of Egyptian black makeup revealed by amperometry at single cells
I. TAPSOBA
Lead-based compounds were used during antiquity as both pigments and medicines in the formulation of makeup materials. Chemical analysis of cosmetics samples found in Egyptians tombs and the reconstitution of ancient recipes as reported by Greco-Roman authors have shown that two non-natural lead chlorides (laurionite Pb (OH) Cl and phosgenite(...)
