Abstract—The convergence of software-defined networking and the Internet of Things widens the attack surface of connected networks and calls for defenses able to detect attacks at the controller's vantage point and to block them there. Earlier work compared deep architectures for denial-of-service attack detection and opened two perspectives: extension to the multiclass setting and integration into an operational intrusion detection and prevention system acting in real time. This article takes up these perspectives in an SDN-IoT context. On ASEADOS-SDN-IoT, a recent dataset that synchronizes device traffic with controller telemetry, we evaluate a deep detector organized as a two-stage cascade covering five traffic classes, comparing six architectures at each stage. The hybrid CNN-BiLSTM network offers the best trade-off, and the cascade outperforms a direct multiclass classifier ev...

Introduction. Les plaies abdominales par arme à feu (PAAF) constituent une urgence chirurgicale vitale, particulièrement dans les zones de conflit armé où les ressources médicales sont limitées. Au Burkina Faso, l'insécurité croissante expose les populations civiles et militaires à ces traumatismes sévères, dont la prise en charge reste mal documentée. Cette étude décrit les aspects épidémiologiques, diagnostiques, thérapeutiques et pronostiques des PAAF au Centre Hospitalier Régional Universitaire de Fada N'Gourma (CHRU-FG). Méthodes. Nous avons mené une étude rétrospective descriptive et analytique du 25 décembre 2024 au 24 décembre 2025, incluant tous les patients hospitalisés pour PAAF. Les données ont été extraites des dossiers médicaux et analysées avec SPSS 25. Les facteurs associés à la mortalité ont été identifiés par le test exact de Fisher et le test de Mann-...

This study provides a regional analysis of mango by-product generation and traceability in the Hauts-Bassins and Cascades regions of Burkina Faso. Through field surveys conducted in samples of 89 processing units and stakeholder mapping, the study quantifies the volume and flow of mango residues and identifies key stakeholders and bottlenecks in the post-harvest chain. Although traceability practices remain largely manual, the study identifies opportunities for digital integration and the added value of utilizing by-products in agro-industrial applications. A total of 52,691 tons of fresh mangoes were processed, primarily from seven varieties. Five types of by-products were identified, with peels, kernels, and sorting waste being the most prevalent. These by-products represented 49.66% of the total processed mango mass. Most by-products were discarded indiscriminately, with o...

Avec l’essor des Technologies de l’information et la communication (TIC), l’agriculture de précision constitue une opportunité stratégique pour améliorer les rendements agricoles au Burkina Faso. L’objectif de cette étude est d’analyser les contraintes actuelles limitant l’adoption de l’agriculture de précision au Burkina Faso. Pour ce faire, des données qualitatives ont été collectées à travers des entretiens semi-directifs auprès des principaux acteurs du secteur dont sept (07) opérateurs privés, 13 directions régionales et 2 directions générales en charge de l’agriculture. Les résultats montrent que l’adoption de la technologie reste limitée par des facteurs tels que le coût élevé de la technologie, un manque de compétences techniques et des contraintes réglementaires. Malgré ces contraintes, l’Etat et ses partenaires techniques et financiers, les instituts de recherche et le secteur...

Dans un contexte d’intensification des crises sécuritaires au Sahel, le Burkina Faso fait face à des déplacements massifs de populations qui fragilisent les moyens d’existence des ménages. La commune de Kaya, principal pôle d’accueil des personnes déplacées internes (PDI), subit une forte pression sur ses infrastructures sociales et économiques. Malgré la multiplication des interventions humanitaires, la question demeure de savoir dans quelle mesure ces actions contribuent réellement au renforcement de la résilience des ménages affectés. Cette recherche vise à évaluer les effets du Projet d’Appui aux Ménages Affectés par la Crise (PAMAC), mis en œuvre par l’Organisation Catholique pour le Développement et la Solidarité (OCADES) Caritas, sur la résilience des ménages bénéficiaires dans la commune de Kaya. La méthodologie adoptée repose sur une approche mixte combinant données quantitative...

Rice is among the most important worldwide staple food grains. However, limited water availability for rice production has resulted in substantial yield reductions. To mitigate this constraint, the adoption of pressurized irrigation systems appears essential for rice production in Burkina Faso. It is therefore crucial to identify genotypes suitable for drip irrigation. It is also important to identify the genotype that integrates the multiple desirable traits for breeding programs. To achieve this goal, a good selection method is required. This study aimed to identify rice genotypes suitable for drip irrigation using the Multitrait genotype-ideotype distance index (MGIDI) and multitrait index–based factor analysis and ideotype design based on best linear unbiased prediction (FAI-BLUP). Twenty rice genotypes were evaluated under drip irrigation during two seasons (2021 and 2022). The data...

In West Africa, cowpea is a key crop valued for its nutritional, ecological, andeconomic value. However, this region of the world frequently suffers from drought,which severely compromises the productivity of this species. Varietal selection, oneof the most effective approaches to adressing this constraint, requires identifyingthe most sensitive stages of development and selecting high-performance varietiesfor breeding programmes. This study evaluated the agronomic responses of sevencowpea genotypes subjected to a 14-day water deficit at four phenological stages(20, 30, 40, and 50 days after sowing) using a completely randomized block designwith three replicates under controlled greenhouse conditions, with the aim ofidentifying genotypes likely to be tolerant at different stages of development andstress levels. Total grain weight (g) per genotype under each water regime wasused as the pr...

In Burkina Faso, the increasing presence of emerging contaminants such as cyanide and dyes from water resources is a major environmental concern related to sanitary diseases. To mitigate this problem, water treatment based on adsorption with local materials offers promising and sustainable alternatives instead to conventional treatment. This work investigated the adsorption potential of activated carbons to remove cyanide and methylene blue (MB)for water purification. The multi-scale methodological approach has combined the production and characterization of activated carbons, experimental applications, and chemical modeling of the retention of emerging pollutants. Activated carbons (AC) were produced by pyrolysis of rice husks at 650°C followed by chemical and physical activation. Batch experiments were carried out using synthetic solutions of cyanide and MB and operating conditions wer...

Dengue fever is a major re-emerging infectious disease, posing risks in low- and middle-income countries, including Burkina Faso. Although antibodies against Aedes aegypti salivary gland extract (SGE) are recognized as reliable biomarkers of exposure to Aedes bites, data from Burkina Faso remain limited. The study compared IgG- specific responses to Ae. aegypti SGE of children (n = 200) residing in Ouagadougou and rural adult cotton farmers (n = 476) in Ziro Province. Rural samples were collected during the high mosquito density season (June to July), while urban samples were collected during the dry season. IgG responses to Ae. aegypti SGE were determined using ELISA. Children’s mean IgG levels are significantly higher in the 11- 15 years of age than in the younger age group (p-value <0.001), and also are significantly different among children residing in the three neighborhoods surveye...
