Prevalence of Malaria among Children between 3 and 59 Months Old in Two Healthcare Districts of Burkina Faso, 2020
Yanogo Pauline Kiswendsida1,2*, Yanogo Chantal2, Halidou Tinto3
Every 75 seconds, there’s a child below 5 years of age who is dying from malaria throughout the world. Burkina Faso, which also suffers from the ravages of malaria, has developed several strategies to respond to the disease including seasonal malaria chemoprophylaxis (SMC). To generate basic data available for the study of the efficacy of a su(...)

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(...)

Fault Distance Location on an Electrical Transmission Line of a Medium-Voltage Network Using a New Solutions of the Telegraphy Equations
D. Konane, W. S. Boris Ouedraogo, W. O. Compaore, A. Zongo, Z. Koalaga and F. Zougmore, "
A fault location method in an electrical network is a combination of procedures, hardware, and software. determining the position of a fault in the network. This method calculates the distance between a reference position and the faulty position. Nowadays, at Société Nationale d'Electricité du Burkina (SONABEL), impedance and reflectometry met(...)

Enhancing Broadband Access in Urban Burkina Faso: A GIS and Machine Learning-Based Geomarketing Approach to FTTx Potential and Alternatives
Kebre Marcel Bawindsom; Kabore Wendpanga Rodrigue; Ouedraogo Sidi Mohamed Galiam; Tapsoba Paul; Sawadogo Alfred
This geomarketing study addresses the challenge of disparate broadband coverage in urban areas of Burkina Faso. Leveraging GIS and unsupervised machine learning techniques, such as hierarchical clustering and polygon segmentation were employed for spatial clustering and prioritization of broadband deployment zones. Through a comprehensive asse(...)

Comparative study of the electronic properties of hexagonal and orthorhombic structures of RMnO3-type perovskites (R=Tb, Dy, Ho and Er) by DFT calculations
Joël Martial Balkoulga, Antoine Béré, Sidiki Zongo, Viwanou Hounkpati, Moussa Sougoti, Sié Zacharie Kam
The electronic properties of perovskite RMnO3 (R=Tb, Dy, Ho and Er) were studied using the density- functional theory (DFT). For each perovskite RMnO3, the ferromagnetic (FM) and antiferromagnetic (AFM) structural parameters in the spin-up and spin-down configurations are optimized. The band structures, the density of states (DOS) and the part(...)

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(...)

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)(...)

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(...)

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(...)

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 thermal degra(...)
