In Vitro Antioxidant and Anticancer Properties of Various E. senegalensis Extracts
Souleymane Fofana, Cédric Delporte, Rafaèle Calvo Esposito, Moussa Ouédraogo, Pierre Van Antwerpen, Innocent Pierre Guissou, Rasmané Semdé and Véronique Mathieu
Although Erythrina senegalensis is a plant widely used in traditional medicine in sub-Saharan Africa, its biological properties have been poorly investigated to date. We first characterized by conventional reactions the composition of several stem bark extracts and evaluated in acellular and cellular assays their pro- or antioxidant properties(...)

Characterization of sugar cane bagasse ash from Burkina Faso for cleaner cement production: Influence of calcination temperature and duration
Moussa Ouedraogo, Moustapha Sawadogo, Issiaka Sanou, Michel Barro, Sory Nassio, Mohamed Seynou, Lamine Zerbo
In this study, the sugar cane bagasse from Burkina Faso has been calcined at temperatures ranging from 550 to 750 °C with a heating stage of 2 or 3 h to produce pozzolanic ashes as supplementary cementitious materials for eco-cement production. The ashes obtained were subsequently characterized for their chemistry, mineralogy, and pozzolanic a(...)

Experimental Study of the Airflow in Natural Convection in an Innovative Prototype of Solar Chimney PowerPlant, under Climatic Conditions in Ouagadougou, Burkina Faso
Salifou Ouédraogo, Moctar Ousmane, Ladifata Mogmenga, Thierry Sikoudouin Maurice Ky, Sié Kam, Joseph Bathiébo
Objectives: In sunny regions, chimney solar power plants are a promising technology because they depend mainly on solar energy. However, chimney solar power plants require an optimal design of the power plant components to improve its reliability and scalability. As the collector is one of the essential components of the solar chimney power pl(...)

Green synthesis and characterization of silver nanoparticles using combretum micranthum leaves extract as bio reductor
Tongonmanegde Léonard Ouédraogo, Sidiki Zongo, Moussa Sougoti, Sié Zacharie Kam, Fabrice Bado, Jean Koulidiati, Antoine Béré
n this work, silver nanoparticles were synthesized from silver nitrate using combretum micranthum leaves extract as a reducing and capping agent. The optical characterization through UV visible spectroscopy revelated a characteristic peak of surface plasmon resonance at 425 nm, while the particle size calculations based on the Mie diffusion th(...)

Hospital preparations of ethanol‐free furosemide oral solutions: Formulation and stability study
Charles Bavouma Sombié, J. E. Kéré Guetambaba, Hermine Zimé Diawara, Josias Yaméogo, Salfo Ouédraogo, Jonathan Goole, Rasmané Semdé
Furosemide is a diuretic frequently used in the therapeutic management of edema associated with cardiac, renal, and hepatic failure and hypertension. However, there are a very low number of pharmaceutical dosage forms containing furosemide that are suitable for children under 6‐ years old. Therefore, there is a real need to develop hospital pr(...)

The effects of salt pretreated with different concentration of lemon juice were
investigated in order to improve the storage stability of dried tomato slices
during six months storage. After six months of storage under controlled condi-
tions, the results revealed that the moisture, color parameters (lightness, L *;

Square-mean pseudo almost periodic solutions of class r under the light of measure theory
MOHAMADO KIEMA AND ISSA ZABSONRE
The aim of this work is to present new concept of square-mean pseudo almost periodic of class r using the measure theory. We use the ergodic process to define the spaces of pseudo almost periodic processes of class r in the square-mean sense. We present many interesting results on those spaces like completeness and composition theorems
and we(...)
