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(...)

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(...)

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(...)

Fire behavior of polymers: comparative study of Tek wood and Fraké wood on a small scale
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(...)

Gestion des déchets plastiques à Koudougou, une ville moyenne du Burkina Faso
Nebilma P. NAGALO, Fulgence T. IDANI, Sidiki ZONGO
Autrefois, considéré comme une source de revenu, les déchets plastiques sont perçus aujourd’hui comme un danger par les écologistes au niveau mondial. A l’instar des grandes villes africaines, la ville de Koudougou fait face à des défis majeurs en matière de préservation de l’environnement. L’objectif de cette étude est d’analyser le(...)

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(...)

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(...)

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(...)

LE SUD-OUEST DU BURKINA FASO A L’EPREUVE DU CHANGEMENT CLIMATIQUE : ENTRE PERCEPTIONS ET STRATEGIES D’ACTEURS
Jean Charles BAMBARA et Ramané KABORÉ
notamment lors de la conférence de Rio de Janeiro et dans les rapports réguliers du GIEC, les pays ont
intensifié leurs efforts pour prévenir les catastrophes prédites par les spécialistes. Le Burkina Faso, dont
l'économie dépend en grande partie sur le secteur primaire, a également mis en place diverses initiatives
d’adaptation pour ren(...)
