Sustainable Irrigation and Fertilization Strategies for Maize in Arid Regions: Insights from Numerical Modeling and Simulation
Siguibnoma Kévin Landry Ouedraogo, Sayouba Kabre, Wenceslas Somda, Marcel Bawindsom Kebre, Francois Zougmore
Climate change and increasing socio-economic pres-sures are intensifying the demand on water resources, particu-larly in arid and semi-arid regions like Burkina Faso. Effective water and fertilizer management are crucial to sustain agri-cultural productivity while minimizing environmental impacts. This study employs HYDRUS 2D to model the coup(...)

ENERGY PROBLEMATIC OF THE POWER FACTOR IN SOLAR INSTALLATIONS: CASE STUDIES, HIGHLIGHTING AND PROPOSED SOLUTIONS
Zoundi Ousmane1*, Nzihou Jean Fidele1, Tissologo Moussa1, Ouattara Frederic1, and Segda Bila Gerard2
The aim of this article is to highlight the consumption of reactive energy and the consequences of not taking it into account in solar installations. Unlike active power, it is responsible for the magnetization or induction of electrical circuits (enabling the transfer of active power) and remains constant (depending on the type of equipment)(...)

Adaptation strategies to cope with the effects of climate variability in the central plateau region of Burkina Faso
ZOMA Vincent
Climate variability presents major challenges across Africa, particularly in Burkina Faso. This article analyses the adaptation strategies implemented by local populations and development actors to cope with this phenomenon in the Central Plateau region. Conducted in October 2023 in three villages in the region, the research combines field obs(...)

Liver Cancer Survival and Prognostic Factors in a High Endemic Area of Hepatitis B
Somda, K.S., Kabore, A.F., Coulibaly, A., Soudre, S.M.O., Vebamba, T., Bere, C. and Sombie, A.R.
Background: Hepatitis B infection is a global public health problem especially
in developing countries with high prevalence, and liver cancer is its most
feared complication. In these countries the majority of infections occur in
early childhood with the corollary of a frequent transition to chronicity and
increased risk of liver cance(...)

Morphological and biological characterization of Spermophagus niger (Motschulsky, 1866) (Coleoptera: Chrysomelidae) from four West African countries
Kabore, E., Koussoube, J. C., Kam, K. W., Sanon, A., & Ilboudo, Z., 2025
In Burkina Faso and many West African countries, Spermophagus niger (L.) is the main insect pest of Hibiscus sabdariffa seeds stored with considerable damage. Variations in bioclimatic conditions can lead to significant changes in the morphology and biology of populations of the same insect species, leading to strains that are morphologically(...)

On a Bi-nonlocal fourth-order difference problem involving the p(k)-Laplacian type operator
I. Nyanquini and S. Ouaro
In this paper, we study a class of bi-nonlocal fourth-order discrete problems involving p(k)-Laplacian operator in a finite dimensional Banach space. By using the variational method and the (S+) mapping theory, we investigate the existence and multi- plicity of nontrivial solutions, subject to the condition that the parameters are sufficiently(...)

Evaluation of corrosion protection performance and color stability of environment-friendly pigmented polyurethane coating
Mamadou Ouedraogo, Tambi Ramde, Boubié Guel, Stefano Rossi
This research is distinctive in its focus on the corrosion protection property, the ultraviolet B radiations (UV-B) resistance, and the color stability of a polyurethane (PU) base coating formulated with 1 % wt. of an environment-friendly inorganic pigment (Bi, Ca, Zn)VO4. The pigment was synthesized and evaluated based on structure, color, an(...)

Développement de l’environnement lettré en langues nationales et construction des identités culturelles » –
SAWADOGO Awa 2ème Jumelle
A l’instar des autres pays de l’Afrique dite francophone, le Burkina Faso, en plus d’avoir
adoubé la langue coloniale imposée depuis 1896 (Bougma 2010) avait littéralement relégué les siennes
au rôle de communication orale. Paradoxalement, KABORE et SAWADOGO (2019) relèvent que les

Antioxidant, Antifungal and Antitermite Activities of Residues from Hydrodistillation of Cymbopogon citratus, Eucalyptus camaldulensis and Mentha piperita
Assétou Sankara, Jean Claude Windéyolsidé Ouédraogo, Schémaéza Bonzi, Marie-France Thévenon, Yvonne Libona Bonzi-Coulibaly
Aromatic plant distillation produces residues rich in phenolic compounds known to be bioactive. In this context, residues from the hydrodistillation of Mentha piperita L., Cymbopogon citratus Stapf, and Eucalyptus camaldulensis Dehnh were chemically and biologically analyzed. The ethanol percentages (70%, 50%, and 30%) were evaluated by determ(...)

Transcription-Based on Pitches an Ontology for the System Knowledge Representation
Pengwendé Zongo, Yamba Dabone & Tounwendyam Frédéric Ouedraogo
This article aims to present an ontological approach for the domain knowledge representation of an intelligent tutoring system for learning transcription based on pitches in the Mooré language. This system that we built allows us to learn the transcription of polysemous words in the Mooré language. In our intelligent tutoring system, the knowl(...)

Short Term Impact of Andropogon gayanus Kunth. on Soil Fertility and Legume Crop Rotation in West Central Region of Koudougou, Burkina Faso
Boussa Tockville Josue Mare, Yiénibirma Josias Lankoande, Issaka Senou, Salifou Traore a and Waldemar Spychalski
The low productivity of land in Burkina Faso is one of the major threats of the agricultural sector. This study aims to evaluate the short-term legume crop impact in a sequence with a short term Andropogon gayanus fallow rotation in order to propose means of degraded lands recovery and their sustainable management. To achieve this goal, a test(...)

Lands Evaluation in Hydromorphic Environment: Case of Developed Rice Lowland Soils in the Province of Ziro, Burkina Faso
Boussa Tockville Josue MARE, Duponibè SOME, Fidèle KABORE , Jean OUEDRAOGO and Edmond HIEN
Sustainable soil management became a major concern for rice farming in Burkina Faso. Rained rice production offers potential thanks to the national rice policy oriented towards the developing of lowlands. However, effective soil fertility management through the promotion of good agricultural practices is essential in this agricultural area to(...)

The unit bundle of a real hyperbolic space
Alfred Touré, Daniel Koama, Mikaïlou Compaoré, Marie Françoise Ouedraogo
The purpose of this article is to study the two homogeneous structures of the unit bundle UH^n of a real hyperbolic space. In both the cases, we determine the -invariant Riemannian metrics. In passing, we examine whether the geodesic flow is an isometry of UH^n when equipped with its Levi-Civita metric. Finally, we study the manifold of geodes(...)

Fire behavior of polymers: comparative study of Tek wood and Fraké wood on a small scale
BAGUIAN Abdoul Faycal1, KOUDOUGOU Mathilde, KOALA Lucmane, DABILGOU Téré, TIENDREBEOGO Olivier, TASSEMBEDO Rodolphe, ZAIDA Justin, SAM Raguilignaba , OUIMINGA Salifou Koucka
Parameters representing the thermal properties of materials are
considered to be specific to thermal inertia, and parameters modulating surface heat
transfer are considered to be related to thermal inertia. The fire behavior of
materials depends on the chemical processes involved in their thermal degradation.
For our study of the therm(...)
