Multiple homoclinic solutions for the discrete $p(X)$-Laplacian problems of Kirchhoff type
Y. Ouedraogo, B. Kone and S. Ouaro
In this paper we consider the discrete anisotropic difference equation with variable exponent using critical point theory. The study of nonlinear difference equations has now attracted special attention as they have important applications in various research areas such as numerical analysis, computer science, mechanical engineering, cellular n(...)

La place des Organisations Non Gouvernementales (ONG) dans la diffusion des foyers améliorés en Haute-Volta (1977-1983)
DEMBEGA Salam
Les années 1970 furent marquées au Sahel par une sécheresse aux multiples conséquences sur la vie des hommes et l’environnement. Pour réduire la consommation du bois de feu en Haute-Volta, des Organisations Non Gouvernementales (ONG) s’engagèrent dans la diffusion des foyers améliorés. Cette étude a pour objet d’analyser la promotion de ces di(...)

The role of scientific research in pearl millet improvement and its impact in Sub Saharan Africa (SSA)
Lardia Ali Bougma *, Adjima Ouoba, Mahamadi Hamed Ouédraogo and Mahamadou Sawadogo
Pearl millet is an essential food cereal for the SSA countries with regards to its fundamental role in food security and its
impact on the rural economy. History enlightens us that pearl millet is a crop linked to this part of Africa. This paper
investigates pearl millet genetic improvement in SSA focusing on breeding evolution in West Afr(...)

Les enjeux du discours philosophique dans le roman africain : le cas de L'Aventure ambiguë de Cheikh Hamidou Kane et La Carte d'identité de Jean-Marie Adiaffi
TIAHO Lamoussa
L’un des traits non négligeables du roman africain réside aussi dans la capacité des écrivains à convoquer le débat philosophique dans l’espace romanesque. La présence du discours philosophique dans la diégèse des romans comme L’Aventure ambiguë de Cheikh Hamidou Kane et La Carte d’identité de Jean-Marie Adiaffi est un signe qui vient attester(...)

African digital health strategic plans analysis: key weaknesses in contextualization, intervention focus, and technological foresight
Bry Sylla; Ansiouonèkou Pascal Somda; Jean Noel Nikiema; Leon Gueswende Blaise Savadogo; Gayo Diallo; Nicolas Meda
Digital health strategies are increasingly being adopted in Africa, but their consistency with best practice planning is poorly documented. 54 countries were screened; 48 had a plan in the Global Digital Health Monitor, and 11 recent plans met the inclusion criteria. Using the “Ready, Extract, Analyze, Distill” methodology and a customized gri(...)

L’intelligence économique au service de la compétitivité des PME Burkinabè
KINDO Hamidou
Introduction : Les PME burkinabè évoluent dans un environnement où la concurrence ne se
limite plus aux éléments financiers ou commerciaux mais porte particulièrement sur la
possession d’une information utile. Dans un tel contexte, « l’intelligence économique » s’avère
être un outil indispensable pour garantir un meilleur positionnement pou(...)

Savoirs endogènes, science et innovation: Vers un cercle épistémologique vertueux en Afrique avec Joseph Ki-Zerbo
SANGARE Noumoutiè
La science et l’innovation sont les moteurs de l’auto-développement des Etats, mais en Afrique ces domaines ont été extravertis par des contingences historiques. Joseph Ki-Zerbo a exploré la question et a proposé le développement endogène comme moyen de sortie du cercle vicieux de l’extraversion. A ce titre, il a posé la nécessite d’assurer un(...)

La mobilité humano-spatiale dans la littérature burkinabè à travers l'oeuvre romanesque de Monique Ilboudo
TIAHO Lamoussa
Signe des temps modernes, le phénomène de la mobilité humaine n’est pas nouveau dans le roman africain qui, depuis les origines s’est beaucoup intéressé au binarisme spatial entre ville et campagne où on assistait à l’évolution des protagonistes des récits sous une forme de va-et-vient incessants entre les deux pôles (ville/campagne). À l’évid(...)

The AMBRE Project: Line-broadening and stellar rotation of ESO/FEROS archived spectra
F. Bado, P. de Laverny, Z. Kam, A. Recio-Blanco, P. A. Palicio and J. Koulidiati
Context. Stellar rotation is a fundamental parameter in studies of the formation and evolution of stars. However, large homogeneous catalogues of rotational velocities derived from high-resolution stellar spectra are still lacking.
Aims. The main objective of this work is to determine the line-broadening parameter (Vbroad), which is a proxy f(...)

Multiplicity of solutions for discrete potential boundary p(k)-Laplace Kirchhoff type equations
B. Moussa, I. Nyanquini, S. Ouaro
In this article, we prove the existence and multiplicity of solutions for discrete p(k)-Laplace Kirchhoff type equations with a po- tential boundary condition.
