On a dual formulation for growing sandpile problem with mixed boundary conditions
N. Igbida, F. Karami, S. Ouaro, U. Traoré
In this work, we introduce and study a Prigozhin model for growing sandpile with mixed boundary conditions. For theoretical analysis we use semi-group theory and the numerical part is based on a duality approach.

A reaction diffusion model to describe the toxin effect on the fish-plankton population
Wendkouni Ouedraogo, Hamidou Ouedraogo, Boureima Sangaré
This paper is aimed at the mathematical formulation, the analysis, and the numerical simulation of a prey-competitor-predator model by taking into account the toxin produced by the phytoplankton species. The mathematical study of the model leads us to have an idea on the existence of solution, the existence of equilibria, and the stability of(...)

Phytochemistry, Antioxidant, and Hepatoprotective Potential of Acanthospermum hispidum DC Extracts against Diethylnitrosamine-Induced Hepatotoxicity in Rats
Jotham Yhi-pênê N’DO, Adama HILOU, Noufou OUEDRAOGO, Ernest Nogma SOMBIE and Tata Kadiatou TRAORE
Background: Burkina Faso is classified among the countries with a high prevalence (˃12%) of hepatitis. Hepatic diseases, such as cirrhosis—related to alcoholism—and hepatitis B and C, are the cause of the increase in cases of liver cancer. They promote the development of cancer by decreasing the natural cell death, causing problems with DNA re(...)

Sustainable approach to recover the hull waste of balanitesoegyptiaca for removal of fluoride from water
Marou GOUROUZA, Zeinabou MAHAMADOU, Mabinty BAYO-BANGOURA, Karifa BAYO, Anne BOOS
The presence of fluoride in water has become a major concern worldwide because of its chronic human
carcinogenic behavior. Developing easily accessible and environmentally friendly disposal strategies is therefore a
challenge for scientists. Heme-activated balaniteoegyptiaca shell carbon has been studied for its ability to adsorb
fluorine f(...)

Impact of pre-treatment by torrefaction and carbonization on temperature field, energy efficiency and tar content during the gasification of cotton stalks
Harouna Gado Ibrahim, Oumar Sanogo, Salifou Koucka Ouiminga, Tizane Daho and Jean Koulidiati
The present study focused on the gasification of raw and pre-treated cotton stalks (CS) by torrefaction and carbonization. Temperature fields, mass balance, energy balance, energy efficiency and tar content of the gas were investigated for the gasification of different types of biomass materials (raw, torrefied and carbonized CS). High tempera(...)

Cowpea is a dual-purpose protein crop which has a high nutritional value. However, many problems such as cowpea aphid-borne mosaic virus limit its production. This study aimed at assessing the resistance of varieties of cowpea to cowpea aphid-borne mosaic virus (CABMV). Thus, a complete diallel cross between five cowpea varieties was done in a(...)

La lutte contre l’antibiorésistance est une priorité pour la santé humaine. De nombreuses bactéries pathogènes résistants aux antibiotiques produisent des facteurs de virulence contrôlés par un mécanisme de régulation appelé Quorum Sensing (QS). L'inhibition du système QS bactérien est une approche thérapeutique plus récente pour contrecarrer(...)
