This article develops a compartmental mathematical model to investigate the impact of excessive social media use on the academic performance of higher education students. Students who are heavily subscribed are classified ‘infected or addicted’ individuals. Their influence on the other naive non-subscribers leading them to become one and by self-curiosity are defined as direct and indirect transmission routes, respectively. The model incorporates two primary control interventions: early awareness programs and continuous regulation of accessibility. Qualitative and numerical analyses of the model dynamics are thus carried out investigating the effectiveness and the benefits of these control measures. The results suggest that a combined strategy, implementing both control interventions at optimal efficacy levels, significantly reduces the ‘addiction’ rate, thereby fostering a healthier aca...

Introduction : La prééclampsie constitue dans le monde un véritable problème de santé tant dans sa fréquence, la diversité de sa prise en charge que dans ses complications. Objectif : il s’est agi d’étudier la prééclampsie sévère dans le département de gynécologie et de médecine de la reproduction du centre hospitalier universitaire Sourô Sanou. Méthodologie : nous avons réalisé une étude transversale à visée descriptive avec recueil rétrospectif des données sur une période d’un an allant du 1er Janvier au 31 Décembre 2019. Ont été incluses dans l’étude 171gestantes admises dans le département et porteuses d’une grossesse au terme de 20 semaines d’aménorrhée (SA) ou plus et chez qui le diagnostic de prééclampsie sévère a été posé au cours de la grossesse, ou du travail d’accouchement. Les données recueillies ont été saisies sur un micro-ordinateur et analysées avec le logiciel EPI inf...

Jute mallow is a leafy vegetable cultivated in urban and peri-urban farming systems in Burkina Faso. This research aims to select high-yielding and stable Jute mallow genotypes through evaluation in three locations. To do this, 20 genotypes were tested at three locations across Burkina Faso. The agronomic data were subjected to two-way analysis of variance and Genotype plus Genotype by Environment (GGE) biplot analysis using R software. The results revealed highly significant (p < 0.01) differences among genotypes for all agronomic traits. In addition, highly significant genotype × environment (GEN × ENV) interactions were observed for all traits. Comparative analysis of the average performance of the genotypes studied showed that plant heights ranged from 78.708 to 134.556 cm for genotypes AZIGA and HBV9. Regarding plant height (134.556 cm), stem diameter (15.181 mm), and number of bran...

Le syndrome de perfusion artérielle inversée (Twin Reversed Arterial Perfusion Syndrome – TRAP) est une forme grave de complication très ??? des jumeaux monochorial perfuseur-perfusé. Nous rapportons ce cas de jumeaux découverts au cours du travail d’accouchement des jumeaux nés par voie basse d’une patiente de 21 ans qui n’a réalisé aucune échographie anténatale. Elle est deuxième et primipare avec un enfant vivant, elle n’a pas d’antécédents particuliers. La grossesse gémellaire était constituée d’un jumeau acardiaque se présentant sous forme d’une masse amorphe et d’un jumeau sans malformations de sexe masculin. Ce cas rappelle l’intérêt des échographies prénatales afin de dépister tôt ce genre de malformations et d’y apporter une prise adaptée afin d’améliorer le pronostic du jumeau pompe.

Climate change, land-use intensification, and agroforestry management are key drivers of soil organic carbon (SOC) dynamics in Sub-Saharan Africa, yet their combined effects remain poorly understood. Using a hierarchical space-for-time substitution approach, we analysed 1,440 soil samples from protected areas, fallows, and croplands across four climatic zones spanning a humid-to-semi-arid gradient in Ghana and Burkina Faso. We also assessed the role of tree canopy cover on SOC stocks and soil properties. Climate was the dominant driver of SOC dynamics, explaining 26.3% of the variation in topsoil SOC, while the interaction between climate and land-use accounted for 34% of the variation in total SOC stocks. The effects of land-use intensification increased along the aridity gradient, causing substantial SOC depletion in croplands within dry sub-humid and semi-arid zones, likely due to red...

In Burkina Faso, Bambara groundnut yields remain low in smallholder agrosystems, partly due to poor soil fertility and limited use of adapted genotypes. Integrating organic fertilization with the selection of high-performing genotypes may enhance crop productivity under Sudano-Sahelian conditions. This study evaluated the agronomic performance of eight Bambara groundnut genotypes under different rates of poultry droppings. A trial with a split-plot design was conducted during the 2023 rainy season, using eight Bambara groundnut genotypes which were subjected to three doses of poultry droppings. Organic fertilization improved soil chemical properties and significantly enhanced plant growth and yield compared with unfertilized plots. Yield responses varied among genotypes, highlighting significant (p < 0.05) genotype × fertilization interactions. Genotypes E62-a and KVS259 performed best...

Introduction La leishmaniose viscérale à Leishmania infantum (LV/LI) reste non rapportée dans l’ouest-africain. Nous décrivons ici une LV/LI autochtone, inédite au Burkina Faso, associée à une myélite. Observation Une adolescente était hospitalisée pour fièvre prolongée, paraplégie flasque, pancytopénie, hépatosplénomégalie, embolie pulmonaire d’immobilisation et pleurésie. Les explorations immunologiques, hématologiques et microbiologiques dont les recherches de tuberculose, notamment sur liquide pleural, frottis médullaire ou biopsie salivaire étaient non-diagnostiques. L’IRM retrouvait une myélite dorsale. Les traitements d’épreuve antituberculeux et immunosuppresseurs de sarcoïdose (méthylprednisolone/adalimumab) étaient sans efficacité, et favorisaient l’efflorescence de nodules cutanés ulcéro-nécrotiques, permettant le diagnostic de LV/LI par PCR sur les prélèvements cutanés et...

Population growth and climate change are putting drinking water resources at risk, making groundwater a key solution to these challenges. In Burkina Faso, more than 80% of the geology consists of crystalline bedrock, which necessitates the search for bedrock aquifers for water supply. The complexity of these aquifers has led to numerous unsuccessful water drillings. Electrical resistivity tomography (ERT) profiles were therefore conducted in the cities of Loumbila and Ziniaré using the resistivity-meter SYSCAL Pro system, in a Wenner-Schlumberger configuration, to better identify the characteristics of potential aquifer zones. ERT field measurements use a series of electrodes spaced 5 m apart to measure electrical resistivity along the profile. The inversion results are presented as cross-sections showing the distribution of the subsurface’s true resistivity as a function of depth along...

In this paper, we propose a critical analysis of recent advances in cybersecurity, particularly the application of deep learning, cyber threat intelligence, and deceptive security. Building on this analysis, we introduce an integrated and innovative approach that combines the collection of attacker traces through deception systems (honeypots) with deep learning techniques, in order to enhance the resilience of cyber defense strategies. Our methodology is structured around three components: (1) constructing a labeled dataset from the traces collected on the T-Pot deception platform, based on the MITRE ATT&CK framework; (2) developing a deep learning model capable of identifying attacker profiles in real time; and (3) integrating an automated incident response mechanism that can trigger countermeasures tailored to the identified profile. This approach seeks to overcome the limitations of c...

This study presents an integrated geostatistical and multivariate clustering framework to characterize hydrogeological variability across 261 boreholes in the crystalline basement aquifers of Burkina Faso. Spatial autocorrelation analysis based on Moran’s I indicates significant spatial dependence for borehole depth (I = 0.088, p = 0.0059) and static water level (I = 0.063, p = 0.0336), whereas discharge exhibits no significant spatial autocorrelation (I = −0.032, p = 0.7847). Hierarchical agglomerative clustering identifies two complementary organizational scales: a functional hydrogeological classification into three clusters (k = 3, s = 0.3045), corresponding to regolith reservoirs, hydrodynamically constrained media, and high-yielding structural fractures, and a broader macro-spatial regionalization into two clusters (k = 2, s = 0.4978). This scale-dependent organization highlights t...
