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(...)

Greenhouse Gas Emissions Assessment in Waste Management: A Case Study of Polesgo Landfill, Ouagadougou, Burkina Fas
Bernard Nana; Sid-Noma Anne-Marie Kinda; Nukunu Komlan Guillaume Attaglo; Issoufou Ouarma; Jean Koulidiati; Antoine Béré
Greenhouse gas (GHG) emissions from waste management are proving to be a major concern in terms of climate change. In terms of methane emissions at national level, studies have shown that the waste sector is second after agriculture, with 12% of emissions. The aim of this study is to quantify the GHG emissions from various waste management uni(...)

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(...)

Thermal Regulation of an Indirect Solar Dryer With Dual Collectors Dual Collectors
Tiendrebeogo Salmwendé Eloi; Tubreoumya G. Christian; Sawadogo E. Sidwaya; Batiana Abdré; Dissa A. Oumar; Bere Antoine
Burkina Faso has plenty of sunshine for most of the year, and it is interesting to carry out solar drying in order to preserve the active ingredients of the harvested products. The drying temperature remains an essential parameter for the quality of the product to be dried. The work presented is part of an experimental study on the temperature(...)

Identification and Mitigation of Weak Points in An Electrical Network for Optimal Solar PV Power Integration
Sami Florent Palm, Celestin Kambou, Adelaide Lareba Ouedraogo, Sayouba Kabre, Sebastian Waita, Thomas Nyangonda
In Burkina Faso, significant initiatives are underway to link multiple Solar Photovoltaic Power plants to the national grid and establish connections with neighboring West African Nations. This endeavor requires careful consideration due to the intermittent nature of Photovoltaic (PV) power generation and the rising electricity demand in Burki(...)

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(...)

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(...)

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(...)

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(...)

BAGUIAN Abdoul Faycal, KOUDOUGOU Mathilde, KOALA Lucmane , DABILGOU Téré , TIENDREBEOGO Olivier, TASSEMBEDO Rodolphe, ZAIDA Justin, SAM Raguilignaba, OUIMINGA Salifou Koucka5
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(...)

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(...)
