2-Oxo-2H-chromen-7-yl 3-methylbutanoate
Akoun Abou, Hypolite Bazié, Ludovic Akonan, Abdoulaye Djandé and Pierre Francotte
The title compound, C14H14O4, was synthesized by O-acylation of umbelliferone
with isovaleryl chloride in the presence of diethyl ether as a solvent and pyridine
as a base. The side chain moiety i.e. the acetate fragment linking to the
methylethyl group is almost orthogonal to the almost planar (r.m.s deviation =
0.020 A ˚ ) coumarin ring(...)

Cross-Analysis of Social Media Opinions in a High-Security Challenge Context
Zombre Payiri Gregoire Wenceslas; Traore Yaya; P. Justin Kouraogo
This study aims to develop an approach for cross-analyzing public opinions on security issues in Burkina Faso, as expressed on social media platforms. We implemented a methodology combining web scraping, API calls, and large language models (LLMs) to collect and analyze data from Fasonet [1], Burkina24 [2] and YouTube [3]. The experiment invol(...)

Evolution des pratiques agricoles endogènes dans les communes rurales du nord du Burkina Faso
Yasmina Téga, Hycenth Tim Ndah, Eveline Compaoré-Sawadogo, Jean-Marie DIPAMA, Johannes Schuler
Au Burkina Faso, on constate une dégradation importante des sols liée à une gestion insuffisante des éléments nutritifs et à des pratiques agricoles inadaptées aux conditions climatiques et pédologiques. Les pratiques d’agroécologie sont des solutions endogènes permettant de répondre à ces défis. L’objectif de cette recherche est d’analyser l’(...)

FREQUENCE ET FACTEURS ASSOCIES DE LA LOMBALGIE CHEZ LA FEMME ENCEINTE A OUAGADOUGOU
Kaboré Fulgence, Ouédraogo Mariam, Ouédraogo Aboubakar, Zongo Enselme, Zabsonré/Tiendrébéogo w Joëlle S, Ouédraogo Dieu-Donné.
Introduction : la lombalgie chez la femme enceinte constitue un problème de santé publique à travers le monde. L’hypersécrétion oestrogénique et la sécrétion de la relaxine, en sont des facteurs favorisants. En Afrique de l’ouest, sa fréquence varie entre 28,9% (Nigéria) et 56% (Bénin). Au niveau national aucune statistique n’est disponible su(...)

Interferon-gamma (IFN-γ) plays a crucial role in resistance to mycobacterial infections, as it is a regulatory cytokine that acts as a pro-inflammatory mediator. Consequently, variants in the gene encoding this cytokine may be associated with a high risk of contracting pulmonary tuberculosis. The present study aimed to investigate the genetic(...)

Comparison of methods to derive the height-area relationship of shallow lakes in west africa using remote sensing
F. Girard, L. Kergoat, E. Nikiema, M. Wubda, R. Yonaba, T. Fowé, A. Abdourhamane Touré, I. Mainassara, M. de Fleury, M. Grippa
In West Africa, lakes and reservoirs play a vital role as they are critical resources for drinkingwater, livestock, irrigation, and fisheries. Given the scarcity of in‐situ data, satellite remote sensing is animportant tool for monitoring lake volume changes in this region. Several methods have been developed to dothis using water height‐area‐(...)

Conjectures à partir du projet de philosopher dans une langue africaine, le mooré du Burkina Faso
Savadogo Mahamadé, Tanella Boni, Souleymane Bachir Diagne, Abdoulaye Elimane Kane, Abel Kouvouama, Abdelmadjid Salim
Derrière ce titre, il s'agit de revenir sur le projet de philosopher dans une langue africaine, le mooré du Burkina Faso, initié depuis plus d'une dizaine d'années par l'auteur du présent propos.
Le projet est bien avancé et a suscité plusieurs publications.
Il est légitime de le soumettre à une évaluation qui oscille entre deux pôles prin(...)

Gold mining on the outskirts of the town of Houndé in Burkina Faso, from enchantment to disenchantment, even annihilation: a dashed hope for sustainable development
Mathieu Nama, Songanaba Rouamba, Joseph Yameogo, Zelbié Bassole, Lassané Yameogo
Our study aims to assess the contribution of gold mining to the sustainable development of the population and the town of Houndé. Both primary and secondary data were used. The study revealed that the installation of an industrial gold mine on the outskirts of Houndé has been the hope of real development. It created 700 direct jobs and 1,000 n(...)

Study of a Mild Solution of a Stochastic Integrodifferential Equation with Non-lipschitzian Coefficients in a Complex Hilbert Space
Wahabo BAGUIAN, Victorien F. KONANE and Claude YAMEOGO
In this work we consider a system of stochastic integrodifferential equations in a complex Hilbert space. We first establish the existence and uniqueness of mild solutions for our equation (1) under non-Lipschitz conditions. Then we show under certain assumptions that the mild solution found is asymptotically stable in mean order n. We obtain(...)

Longitudinal impact of past-year reproductive coercion on contraceptive use dynamics in Sub-Saharan Africa: evidence from eight population-based cohorts
Wood S. N., Haley L. Th., Guiella G., Mosso R., Gichangi P., Kibira S.P.S., Makumbi F. , Akilimali P., OlaOlorun F., Omoluabi, Decker M.
Background: Reproductive coercion (RC) is a type of abuse where a partner intentionally attempts to interfere with fertility through deception or violence, often by manipulating one’s contraceptive use or reproductive decision-making. Cross-sectional studies on the magnitude of RC across sub-Saharan Africa have noted associations with contrace(...)

Sugarcane (Saccharum spp.) is an important interspecific hybrid crop grown for sugar and ethanol production in tropical and subtropical regions around the world. However, its vegetative propagation makes it vulnerable to viral diseases which pose a serious threat to crop yield and quality. Several viruses belonging to species in the genus Mast(...)

Diffusive convective elliptic problem in variable exponent space and measure data
Safimba Soma , Ibrahime Konaté and Adama Kaboré
In this article, we study a class of convective diffusive elliptic problem with Dirichlet
boundary condition and measure data in variable exponent spaces. We begin by introducing an
approximate problem via a truncation approach and Yosida’s regularization. Then, we apply the
technique of maximal monotone operators in Banach spaces to obtain(...)

The hydroxyurea is a save, affordable and essential medicine for sickle cell disease (SCD), reducing painful crises and mortality. To foster the prescription of hydroxyurea for patients with SCD in sub-Saharan African countries, the scientific advisory board of Drep.Afrique, a non-governmental organization dedicated to SCD in Africa, has devel(...)
