INTRA AND EXTRA HOST MATHEMATICAL MODELING OF HIV VIRUS INFECTION DYNAMICS 1, 2
Boukary BEYI, Famane Kambiré, Zongo Gérard, Gabriel BISSANGA
In Burkina Faso, there have been instances of COVID-19 and population displacement due to insecurity and terrorism since 2019 through 2021. These factors may contribute to risky behavior and lower guards against contracting AIDS among the population. Being infected with the HIV virus indicates that the individual is either not receiving treatm(...)

Validation and Investigation of Correlations to Determine Daily Mean Values of Climatic Parameters
Ouedraogo Souleymane, Nana G. Gilbert, Lankouandé Roland, Ky S. M. Thierry, Kam Sié and Bathiebo D. Joseph
This study evaluated selected correlation models for estimating daytime profiles of global solar radiation on a horizontal surface and ambient temperature at a measurement site in Ouagadougou, Burkina Faso. Experimental data were collected using a pyranometer, a K-type thermocouple and a data logger installed at Joseph KI-ZERBO University. Mea(...)

Theoretical and experimental study of the temperature profile of a greenhouse dryer with walls made of adobe bricks.
Bailou Oumar, Tubreoumya Guy. C., Ouedraogo Emmanuel., Tiendrebeogo, Eloi. S., Sanfo Stanislas., Dissa, Alfa. Oumar, & Bere Antoine
walls made of adobe (clay) bricks, a local material known for its high thermal inertia. The aim is to optimize the thermal performance of this dryer in order to improve the preservation of agricultural products, particularly in tropical regions. The prototype dryer, designed with a 15° sloping glazed roof and adobe walls, was studied using a c(...)

SOLVING THE KORTEWEG-DE VRIES EQUATION BY A NUMERICAL METHOD
Gérard ZONGO, Ousséni SO, Geneviève BARRO
In one of our articles published in 2017 [12], we used the SBA method to show its simplicity in solving the Schrödinger equation. In this paper, we propose a solution to the Korteweg-de Vries (KdV) equation using the SBA method.

Prototype fabrication of a CPV made of Gregorian homogenizer concentrator and experimental investigation of its uniform illumination according to sun misalignment
Stanislas SANFO, Serge Dimitri Bazyomo, Tizane Daho, Abdoulaye Ouedraogo
In the field of Photovoltaic Concentration (CPV) technologies, the design of a concentrator to ensure a uniform distribution of irradiation is an issue. In fact, concentrator illumination varies with the sun’s misalignment, and series-connected cells performances are limited by the less illuminated cell. This study investigates the performance(...)

Experimental Determination and Modeling of Desorption Isotherms of the Tomato "Lycopersicum esculentum"
Roland Lankouandé, G. Gilbert Nana , Souleymane Ouedraogo , Kalifa Palm , Frédéric Ouattara and Sié Kam
The aim of this work is to make a contribution to the drying of tomatoes. The purpose of this contribution is the experimental determination of the desorption isotherms of a variety of tomato (one of the most widespread on the Burkinabe market place) using the static gravimetric method at temperatures of 25°C, 40°C and 50°C. It is more specifi(...)

Contribution to the estimation of the solar potential on the ground by semiempirical methods and based on the thermal zoning of Burkina Faso
GUENGANE Hassime*, BADO Nébon , NANA G. Gilbert , BAILOU Omar ,OUEDRAOGO Boukaré, DIANDA Boureima and BATHIEBO D. Joseph
In this paper, we evaluate the solar potential of Burkina Faso by a numerical simulation based on four
theoretical models most used in the literature. We validate the numerical results obtained using the solar radiation values recorded on the meteorological sites installed in the different zones defined from the determined climatic zoning th(...)

A GENERALIZED REVIEW ON HOMOGENIZATION AND TWO-SCALE CONVERGENCE
GÉRARD ZONGO, OUSSÉNI SO, GENEVIÈVE BARRO, BLAISE SOMÉ
We study homogenization and two-scale convergence. Homogenization is a mathematical concept that makes it possible to develop a global model of the behaviour of a physical structure evolving in a heterogeneous structure. The behaviour of this physical structure will therefore be studied in a homogeneous environment, which greatly facilitates c(...)

Modeling of Heat Transfer in a Habitat Built in Local Materials in Dry Tropical Climate
Abdoulaye Compaoré, Boureima Dianda , Gilbert Nana , D. Joseph Bathiebo , Belkacem Zeghmati , Xavier Chesneau and Stéphane Abide
A numerical modeling of heat transfer in a habitat whose walls are in local materials (compressedearth blocks) is presented. The transfer equations based on the nodal method are solved by animplicit finite difference method and the Gauss algorithm coupled to an iterative procedure. It wasanalyzed the influence of the rate of air exchange, the(...)
