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(...)

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(...)

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(...)
