LIGHT CONCENTRATION SOLAR CELL: TEMPERATURE PROPER AND DYNAMIC EFFECTS ON ELECTRICAL PARAMETERS DETERMINED BY USING J-V AND P-V CHARACTERISTICS
MAHAMADI SAVADOGO, AMADOU KONFE, IDRISSA SOURABIE, BOUBACAR SORO, RAMATOU KONATE, MARTIAL ZOUNGRANA, ISSA ZERBO, DIEUDONNÉ JOSEPH BATHIEBO
The solar cell is assumed to be under light concentration (C=50 Suns) which leads us to take into consideration the
electric field induced by electrons concentration gradient. We also take into consideration temperature influence on
electron and hole diffusion parameters, on carrier generation rate, on carrier intrinsic concentration and on(...)

Use of Multidisciplinary Approaches for Groundwater Recharge Mechanism Characterization in Basement Aquifers: Case of Sanon Experimental Catchment in Burkina Faso
Moussa Bruno Kafando, Mahamadou Koïta, Mathieu Le Coz, Ousmane Roland Yonaba, Tazen Fowe, Cheick Oumar Zouré, Moussa Diagne Faye and Babacar Leye
In Burkina Faso, the basement aquifers represent a major asset in terms of quantity and quality, for both drinking and irrigation purposes for rural populations. They provide water resources that can guarantee the long-term needs of the populations, provided that a sustainable management policy for these resources is adopted. Yet, any groundwa(...)

Modeling Bat Species Richness and Spatial Distribution in Burkina Faso.
Kangoyé Napoko Malika, Ouéda Adama, Silga Rimwaodo Pierre, Ouédraogo Idrissa, Guenda Wendengoudi & Kabré Boureima Gustave (2021).
The spatial distribution of bats in Burkina Faso is little-known. Previous studies have only described the bat species’ richness in Burkina Faso. This study
was conducted to highlight bat species’ richness distribution within Burkina
Faso and environmental variables that influence this distribution with the aim
to give support for prote(...)

Hepatoprotective Effects of Calotropis procera (Ait.) R. Br Root Bark Extracts against Diethylnitrosamine Induced Liver Injury in Rats
Ernest Nogma Sombié, Adama Hilou, Noufou Ouédraogo, Jotham Yhi-Pênê N’do, Dramane Paré, Tata Kadiatou Traoré, Geoffroy G. Ouédraogo and André Tibiri
Background: Diethylnitrosamine (DEN) is a hepatotoxin whose metabolic activation by liver cytochromes P450 is responsible for the necrosis, mutagenicity and carcinogenicity of liver cells. The purpose of this study was to evaluate the protective effects of Calotropis procera roots bark against DEN induced hepatocellular damage in rats.

This study aims to evaluate the expression of genes implicated in
three Jatropha curcas ecotypes mechanisms of protection against
drought in Burkina Faso. Three drought component factors
(sunlight intensity, water deficit, and sunlight associated with
water deficit) and three genes including APX1 (cytosolic
ascorbate peroxidase), JcHSP1 a(...)

Un territoire rural sous influence urbaine dans l’interface Ouagadougou-Komsilga
Mathieu ZOUNGRANA, Lassane YAMEOGO et Assonsi SOMA
La croissance démographique de Ouagadougou occasionne un
besoin grandissant de logements et de terrains. Cette ville ne
disposant plus d’espaces, les citadins ont recours aux communes
rurales périphériques où les terres sont encore disponibles. Dès
lors, de nombreuses mutations du foncier rural s’opèrent dans
l’interface Ouagadougou-Komsi(...)
