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(...)

Repérage de la dépression selon l’échelle de Beck chez les patients atteints de cancers urologiques au chu-yo de Ouagadougou au Burkina Faso
Djibrilla Moussa, Oumou Ousseyni Zika, Mamadou Teguera, Kapouné Karfo
La dépression est un problème de santé publique. Elle est fréquente chez les patients atteints de cancers de façon générale. Nous avons mené une étude prospective transversale du 1er mai au 31 Aout 2021. Les données étaient collectées auprès des 128 patients avec le questionnaire pré établi et l’échelle de Beck à 21 items. L’usage de l’échelle(...)

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(...)

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(...)

Contribution of the Rapid LAMP-Based Diagnostic Test (RLDT) to the Evaluation of Enterotoxigenic Escherichia coli (ETEC) and Shigella in Childhood Diarrhea in the Peri-Urban Area of Ouagadougou, Burkina Faso

Abstract
The estimates of enterotoxigenic Escherichia coli (ETEC) and Shigella burden in developing countries are limited by the lack of rapid, accessible, and sensitive diagnostics and surveillance tools. We used a “Rapid LAMP based Diagnostic Test (RLDT)” to detect ETEC and Shigella in diarrheal and non-diarrheal stool samples from a 12-mon(...)

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(...)

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(...)

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(...)

This work focused on the impacts of the base doping rate (Nb) and the emitter doping rate (Ne) on the internal
quantum efficiency (IQE) of a bifacial polycrystalline silicon solar cell, under static conditions and monochromatic
illumination. IQE is defined as the ratio of the number of electron-hole pairs or charge carriers generated to the(...)

Wastewater from healthcare centers in Burkina Faso is a source of ESBL, AmpC-β-lactamase and carbapenemase-producing Escherichia coli and Klebsiella pneumoniae
Garba, Z., Bonkoungou, I.O.J., Millogo, N.O. et al.
Background Extended-spectrum β-lactamase (ESBL), plasmid-mediated AmpC-β-lactamase and carbapenemase-
producing Escherichia coli and Klebsiella pneumoniae have spread into the environment worldwide posing a potential
public health threat. However, the prevalence data for low- and middle-income countries are still scarce. The aim
of this stu(...)
