Le Conseil National de la Révolution (CNR) et la gestion de l’électricité au Burkina Faso (1983-1987)
DEMBEGA Salam
Depuis la nationalisation de son secteur énergétique en 1968, la Haute-Volta tente de vulgariser l’usage de l’électricité. Essentiellement produite à partir d’hydrocarbures importés et aux coûts en constante augmentation, cette énergie reste limitée à un cercle restreint de villes où sa gestion était marquée par des déficits liés au manque de(...)

Optimization of a High Capacity Industrial Bar Press for Jatropha Curcas Oil Extraction
Moussa Abdoul-Aziz , Sidibe Sadio Sayon , Ouedraogo Abdoulaye , Ouedraogo Emmanuel , Ousmane Moctar , Coulibaly Ousmane
This study allowed us to achieve the optimal yield for the extraction of Jatropha Curcas oil from the main operating variables of an industrial press. We used an industrial bar press with a large extraction capacity to carry out this work. Two interesting and indicative parameters on the influence of the efficiency of the pre(...)

Preparation and characterization of foamed concrete using a foaming agent and local mineral resources from Burkina Faso.
Alassane Compaoré, Moustapha Sawadogo, Youssouf Sawadogo, Moussa Ouedraogo, Brahima Sorgho, Mohamed Seynou, Philippe Blanchart, Lamine Zerbo,
The paper describes lightweight-foamed concretes (LFC) that were formulated from cement, natural sand, and
foam from a foaming agent with densities of 600 and 700 kg/m3. The identified mineral phases in the cement are
alite, belite, Celite, ferrite, calcite, and gypsum. The obtained foamed concretes have a porosity varying from
29.17 to 37.(...)

Modelling and optimisation of ultrasound‑assisted extraction of roselle phenolic compounds using the surface response method
Abdoudramane Sanou, Kiessoun Konaté, Kaboré kabakdé, Roger Dakuyo, David Bazié, Sama Hemayoro & Mamoudou Hama Dicko
Extracts from Hibiscus sabdariffa L. (roselle) have been used traditionally as a food, in herbal medicine, in hot and cold beverages, as flavouring or coloring agent in the food industry. In vitro and in vivo studies and trials provide evidence, but roselle is poorly characterised phytochemically due to the extraction processes. The optimizati(...)

General Features of Food Import in Burkina Faso
Diéni I, Bagré TS, Traoré KA, Djibrine MA, Bako Evariste, Soro DK, Nikiema MEM, Tapsoba F, Zongo O, Savadogo EH and Barro N
The flow of food goods from producers and importers to consumers is ensured by a large number of traders, including wholesale and retail. Food imports are a socio-economic fact in Burkina Faso. Due to the structural but also cyclical inadequacy of national production to meet the population’s needs for food, it has seen a significant rise in re(...)

G6PD Deficiency and COVID-19 in Burkina Faso: A Possible Link?
Abdoul Karim Ouattara, Lassina Traoré, Tégwendé Rebeca Compaoré, Théodora Mahoukèdè Zohoncon, Jacques Simporé
Burkina Faso is a malaria-endemic country, with a high incidence of G6PD deficiency (G6PDd), which recorded its first case of COVID-19 in March 2020. G6PDd leads to a decrease in the efficiency of erythrocytes to combat oxidative stress, while SARS-CoV-2 infection induces massive production of Reactive Oxygen Species (ROS) in patients. In the(...)
