Optimization of the Extraction of Phenolic Compounds from Eucalyptus camaldulensis Dehnh Leaves Using Response Surface Methodology
OUATTARA Bassalia, SEMAY Irène, OUEDRAOGO Jean Claude W., GERBAUX Pascal, OUEDRAOGO Igor W. K.
In this work, the optimization of phenolic compounds extraction from Eucalyptus camaldulensis leaves was carried out by applying a response surface methodology (RSM) approach. The influence of different parameters i.e., the liquid-to-solid ratio, the temperature and the extraction time have been jointly tested by maceration in an ethanol–water(...)

Assessment of the thermal efficiency of a concentrated photovoltaic/thermal (CPV/T) hybrid system with water as heat transfer fluid,
KONFE Amadou, KORGHO Bruno, Nana G. Gilbert, BAGBILA Eloi, AMADOU Oumarou Fati, KAM Sié
Interest in solar energy is growing by the day, because it is clean and unlimited. Concentrated
photovoltaic-thermal (CPV/T) systems are one of the systems that are attracting a great deal of
attention among solar energy systems. In this work, a study of a hybrid concentrated photovoltaicthermal
(CPV/T) system that enables the simultaneous(...)

Thermal Study and Modeling of the Cold Room of a Solar Adsoption Refrigerator
Amadou Konfe, Mahamadi Savadogo, Loukman Ouedraogo, Ousmane Moctar, Sié Kam
In this work, we are interested in the study of the thermal exchanges which
take place at the evaporator of an adsorption refrigerator. Due to the cost of
designing experimental devices and the impossibility of studying the influence
of certain parameters experimentally, an alternative would be simulation.
The aim is to provide a model for(...)

Evolution des indicateurs d’alerte précoce de la résistance aux antirétroviraux au Burkina Faso entre 2014 et 2017.
OUEDRAOGO Smaïla, DIALLO Ismaël, YOLI Bapougouni Philippe Christian, ROMBA Issa, SARIGDA Maurice
L'utilisation des antirétroviraux (ARV) à grande échelle aux personnes vivant avec le VIH
(PVVIH) s'accompagne d'un développement de résistance au VIH (R-ARV). Nous avons déterminé la
performance de trois indicateurs d’alerte précoce (IAP) associés à un risque élevé d'émergence de RARV
au Burkina Faso à travers une étude transversale répété(...)

Les Touaregs Face à l'État colonial et postcolonial en Haute-Volta/Burkina Faso (1919-1987)
KABORE Koudbi
La construction de l’État-nation en Afrique s’accompagne souvent d’une exacerbation des revendications identitaires d’ordre ethnique ou religieux. Déjà important sous le régime colonial en réaction aux contraintes coloniales, le regain identitaire sous régime d’indépendance est perçu comme s’insérant dans des dynamiques centrifuges de négation(...)

Etude comparative des composés phénoliques de quatre variétés de Sorghum bicolor cultivées au Burkina Faso
Crépin I. Dibala, Raymond P. Barry and Mamoudou H. Dicko
Sorghum bicolor fait partie des céréales les plus riches en composés phénoliques à potentiel nutritionnel dans l’alimentation humaine et animale. L’étude a été réalisée dans l’objectif d’évaluer les teneurs en composés phénoliques des organes de quatre variétés (Framida, Sariaso 19, Sariaso 14 et Gnossiconi) du Burkina Faso. Les macérés d’acid(...)

Farmers’ Perception of Indigenous Seasonal Forecast Indicators in North Central Burkina Faso
KABORE Pamalba Narcise, ZON Aboubacar-Oumar, BAMBARA Dasmané, KOUSSOUBE Souleymane, OUEDRAOGO Amadé
West African Sahel is one of the most exposed areas to the adverse effects of climate variability in the world. All agricultural production system s are affected. However, farmers use indigenous knowledge that enable them to make short, medium, and long term seasonal predictions in order to adapt their agricultural calendar to these climatic r(...)

The Middle Stone Age of Atlantic Africa: A critical review
Telmo Pereira, Luiz Oosterbeek , David Pleurdeau, Abdoulaye Camara, Hamady Bocoum , Djibril Thiam , Raphael A. Alabi, Lassina Koté , Lassané Toubga, Maria Helena Benjamim, Alma Nankela, Daniela de Matos
Evidence of early Homo sapiens populations at the Atlantic coast of Africa remains relatively poorly known in relation to other regions of the continent. Nevertheless, available data across the continent provides a good starting point for current and future research investigations. The many sites known, documented and studied contribute in an(...)
