p(.)-Elliptic inclusion problem with natural growth term and Fourie type Boundary condition
I. Konaté, S. Ouaro
In this paper, we discuss the existence of renormalized and entropy solutions of nonlinear elliptic problems governed by the general p(.)-Leray-Lions type operator with a natural growth term subject to L1 data in the interior of the domain and Fourier type condition on the boundary. We first introduce a sequence of approximated prob- lems by r(...)

THERMAL PERFORMANCE OPTIMIZATIONS OF A HEMISPHERICAL SOLAR COOKER WITH ALUMINUM SHEET CONCENTRATORS: APPLICATION TO FOOD COOKING
Ladifata Mogmenga, Bouto Kossi Imbga, Thierry, Sikoudouin Maurice Ky, Salifou Ouedraogo, Sie Kam, Joseph Dieudonne Bathiebo.
Cooking is a method of transforming food by exposing it to heat. Solar cookers allow us to cook food using the heat generated from the sun's rays. In this work, we present an experimental study of a hemispherical solar cooker tested with and without glazing. In the context of sustainable development, in order to reduce environmental impact, th(...)

The migration experience and mental health in the context of insecurity: evidence from Burkina Faso
Hervé Bassinga, Alexandra Tebkieta Tapsoba, Bruno Yempabou Lankoandé, Nabié Douba, Mamadou Soura, Roch Modeste Millogo, Yacouba Compaoré, Soumaïla Ouedraogo & Daniel Mwanga
Background
Since 2015, recurrent terrorist attacks in Burkina Faso have caused large-scale displacement, impacting the psychological health of affected populations. This study explores the effects of migration forced or voluntary on depression and anxiety among adolescents and young people aged 15–24, in line with SDG 3, which aims to “ensure(...)

Breaking with traditions: Who are the women with attitudes, norms and behaviors that support ending female genital mutilation in Burkina Faso?
Ilene S. Speizer, Elizabeth Gummerson, Fiacre Bazie, Meagan E. Byrne, Yentema Onadja, Phil Anglewicz, Georges Guiella
Studies examining norms and behaviors around female genital mutilation (FGM) are needed to accelerate progress towards the elimination of this harmful practice. This study uses nationally representative data from a pilot FGM module among women ages 15–49 from Burkina Faso collected in 2023/2024. Three main outcomes related to attitudes, norms(...)

Can permanganate oxidizable carbon, microbial respiration, and carbon mineralization rate reflect carbon dynamics across land use and pedo-climate gradients in West African semi-arid zones?
Gannouka Nadjire, Alimata Arzouma Bandaogo, Amanuel W. Gebremichael, Oumarou Ouédraogo and Joseph Issaka Boussim
Climate variability, soil type, land use, and vegetation structure modulate soil organic carbon (SOC) dynamics, but their effects on sensitive soil carbon indicators are not adequately quantified in semi-arid ecosystems. This research examined the independent and synergistic impacts of pedo-climate, land use, and canopy cover on permanganate o(...)

Growth dilemmata: The case of African firms
Abdoulganiour Almame Tinta
In this study, we exploit panel data of 2450 manufacturing firms from a sample of 30 African
countries from 2013 to 2023 to examine the link between firm performance and innovation. Focusing
on innovation and firm growth, this study addresses R&D activities, product innovation, process
innovation, and organizational practices. Applying vari(...)

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(...)

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(...)

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(...)

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(...)
