Background and Purpose: The pharmacology of polyphenol metabolites on beta‐ cell function is largely undetermined. We sought to identify polyphenol metabolites that enhance the insulin‐secreting function of beta‐cells and to explore the underlying mechanisms.
Experimental Approach: INS‐1 beta‐cells and rat isolated islets of Langerhans or per(...)

Nonlinear Neumann problems involving p(x)-Laplace operator and measure data
E. Nassouri, S. Ouaro, U. Traoré
In this paper we study the existence and uniqueness of entropy solution to the class of nonlinear p(⋅)-Laplace problems of the type div(Φ(∇u−Θ(u)))+|u|p(x)−2u+α(u)∋μ with μ a diffuse measure and a Neumann nonhomogeneous boundary conditions of the form Φ(∇(u)−Θ(u))⋅η+β(u)=g. The functional setting involves Lebesgue and Sobolev spaces with varia(...)

Structural stability for nonlinear Neumann boundary p(u)-Laplacian problem
S. Ouaro, N. Sawadogo
This paper is devoted to the study of nonlinear homogeneous Neumann boundary p(u)-Laplacian problem of the form
{b(u)−diva(x,u,∇u)=fa(x,u,∇u).η=0in Ωon ∂Ω,
where Ω is a smooth bounded open domain in ℝN, N≥3 and η the outer unit normal vector on ∂Ω. The existence and uniqueness results of weak solution and the structural stability result are(...)

Solid Waste Management in Africa: Governance Failure or Development Opportunity?
Linda Godfrey, Mohamed Tawfic Ahmed, Kidane Giday Gebremedhin, Jamidu H.Y. Katima, Suzan Oelofse, Oladele Osibanjo, Ulf Henning Richter, Arsène H. Yonli
Waste management is a social, economic, and environmental problem facing all African countries. If the 2030 Agenda for sustainable development is to be achieved, sustainable waste management approaches must be an environmental and public health imperative deserving political priority. Current reasons for the poor management of waste in Africa,(...)

Prevention of mother-to-child transmission (PMTCT) of HIV: a review of the achievements and challenges in Burkina-Faso
Laure Stella Ghoma Linguissi, Tani Sagna, Serge Théophile Soubeiga, Luc Christian Gwom, Céline Nguefeu Nkenfou, Dorcas Obiri-Yeboah, Abdoul Karim Ouattara, Virginio Pietra, Jacques Simporé
Background: Burkina-Faso's HIV/AIDS program is one of the most successful in Africa, with a declining HIV prevalence and treatment outcomes that rival those of developed countries. Prevention of mother-to-child transmission (PMTCT) guidelines in Burkina-Faso, initiated in the year 2000, were revised in 2004, 2006 and 2010. The guideline docume(...)

Distribution of quinolone resistance gene (qnr) in ESBL- producing Escherichia coli and Klebsiella spp. in Lomé, Togo
Fortune Djimabi Salah, Serge Théophile Soubeiga, Abdoul Karim Ouattara, Adodo Yao Sadji, Amana Metuor-Dabire, Dorcas Obiri-Yeboah, Abiba Banla-Kere, Simplice Karou, Jacques Simporé
Background: Qnr genes are known to confer a low-level resistance to fluoroquinolone in Enterobacteriaceae. They are often found on the same resistance plasmids as extended spectrum β-lactamase (ESBL) and constitute the most common antibiotic resistance mechanism. This study aimed to detect the presence of qnr genes in ESBL-producing E. coli an(...)

Derivations and Dimentionally Nilpotent Derivations in Lie Algebras
Abdoulaye DEMBEGA , Amidou KONKOBO, MOUSSA OUATTARA
In this paper, we first study derivations in non nilpotent Lie triple algebras. We determine the structure of derivation algebra according to whether it admits an idempotent or a pseudo-idempotent. We study the multiplicative structure of non nil dimensionally nilpotent Lie triple algebras. We show that when n=2 p+1 the adapted basis coincides(...)

New approach of interpretive method of hydrogeological prospecting and electrical resistivity geophysics data: improvement of water drilling siting techniques in the field of crystalline soils of Burkina Faso (West Africa)
Césard Millogo, Samuel Nakolendoussé, Sâga Sawadogo, Julien Nikiéma
This work is a contribution to the improvement of bore holes siting techniques through a new interpretative approach to hydrogeological and geophysical electrical resistivity prospecting data. Its objective is to make drinking water accessible to all through the reduction of negative drilling rates, which is very recurrent in the crystalline t(...)

La valence verbale en wɩnɩ̃ɛ̃
Yacouba KOURAOGO
La valence verbale est une catégorie sémantico-syntactique associée au verbe.
Sémantiquement, elle réfère au nombre de participants qui jouent un rôle précis dans
le type de procès signifié par le verbe. Syntaxiquement, elle réfère au nombre
d’arguments, c’est-à-dire au nombre d’éléments nominaux, qui entretiennent une
relation grammatical(...)

L’insécurité foncière au cœur des aménagements agricoles de l’Etat : la traduction de l’échec d’un modèle d’auto-promotion paysanne dans une zone de migration
MOYENGA Paul-Marie
Par quels mécanismes les logiques informelles de terroir parviennent-elles à influencer la gouvernance foncière dans des espaces appropriés par l’Etat ? Telle est la préoccupation au fondement de cette étude. Elle trouve sa pertinence dans le fait que les aménagements agricoles au Burkina Faso connaissent une situation d’insécurité foncière co(...)

Performances des filles dans les sciences, mathématiques et technologies : essai d’une analyse socio-institutionnelle (SMT)
HIEN Y Christophe, SORE Zakaria et OUEDRAOGO Félix
À la traine au début de la décennie 1990, le Burkina Faso a connu un accroissement des taux de scolarisation dans les différents ordres d’enseignement, ces dernières années. Si les indicateurs connaissent une augmentation, il reste qu’il existe des disparités, surtout au niveau du post-primaire et du secondaire. En effet, filles et garçons son(...)
