This study examines the impact of the aerothermal factors of an indirect solar dryer on the intermittent and continuous drying dynamics of four crops: mango, banana, potato, and sweet potato. The experiment was conducted under sustained global solar radiation reaching 1000 W?m?2, with drying temperatures ranging from 55?C and controlled forced convection airflow to stabilize the airstreams. The study of thermal profiles and drying kinetics shows that intermittent processing controls mass transfer by promoting internal water redistribution during pause phases, preventing hardening and maintaining a steady evaporation process. The dynamics of moisture migration are quantified by contrasting effective diffusion coefficients Deff: 2.67 × 10?9 m2?s?1 for mango, 9.08 × 10?10 m2?s?1 for banana, 8.39 × 10?10 m2?s?1 for potatoes, and 7.63 × 10?10 m2?s?1 for sweet potatoes. These figures, which ar...

This article examines the word form bɔ ̀ r in Bisa Barka, a minority language spoken in Burkina Faso. It is necessary to determine whether this is a case of polysemy or homophony. Our analysis leads us to conclude that Bisa Barka possesses several morphemes with the signi®er bɔ ̀ r, whose signifieds are unrelated; they are therefore homophones.

Introduction : L'hémodialyse chez l'enfant a bénéficié de progrès importants au cours des 20 dernières années. L'objectif de la présente étude était de faire l'état des lieux de l'hémodialyse pédiatrique à Ouagadougou au Burkina Faso. Patients et Méthodes: Il s'est agi d'une étude rétrospective sur une période de cinq ans allant du ler janvier 2014 au 31 décembre 2018. Ont été inclus dans l'étude, les enfants de 0 à 15 ans en hémodialyse durant la période de l'étude, au Centre Hospitalier Universitaire Yalgado-Ouédraogo et au Centre Hospitalier Universitaire de Tengandogo (CHU-T). Résultats : Cinquante-quatre enfants hémodialysés ont été inclus dans l'étude. La fréquence de l'hémodialyse était de 59,3% chez les enfants en insuffisance rénale aiguë (IRA) et de 40,7% chez les enfants au stade 5 de la maladie rénale chronique (MRC). L'âge moyen des enfants était de 10,8 ÷ 4,6 ans (2 -15 ans...

Background Cervical cancer remains a leading cause of cancer-related morbidity and mortality among women in sub-Saharan Africa, despite effective screening methods. This study examined individual- and household-level predictors of ever having been screened for cervical cancer in 5 West African countries and residual between-cluster variation using multilevel models, based on recent nationally representative data. Methods We analyzed Demographic and Health Survey (DHS) data from Burkina Faso (2021), Côte d’Ivoire (2021), Ghana (2022), Mali (2023–2024) and Senegal (2023). The sample included women aged 15–49 years with complete information on ever-screening for cervical cancer. Two-level logistic random-intercept models (women nested within clusters) were fitted to estimate adjusted odds ratios (aORs) with 95% confidence intervals (CIs) and residual between-cluster variation through t...

Pectinases are enzymes of major industrial interest. This study aimed to isolate and characterize pectinolytic bacteria obtained from decomposing fruit and optimize the composition of the culture medium. Bacteria were isolated on a reconstituted, selective pectin-enriched medium. Active colonies were characterized by morphological observations, biochemical tests, and molecular identification of 16S rDNA. Of the 55 isolates selected, 12 (21.81%) were pectinolytic. All isolates were Gram-positive, predominantly bacillary, and positive for the citrate test. Five strains exhibited γ-haemolysis, indicating that they were non-haemolytic. Based on 16S rRNA gene sequencing, four of these bacteria that expressed high pectin degradation indices were related to Lactiplantibacillus plantarum, Acetobacter tropicalis, Bacillus amyloliquefaciens, and Bacillus subtilis. The B. amyloliquefaciens strain i...

Urban infrastructure plays a crucial role in the socio-economic development of regions, especially in Africa, where rapid urban growth is creating pressing demands for infrastructure. Against this backdrop, Burkina Faso has introduced the rotating celebration of 11 December to stimulate the development of secondary towns. In Ziniaré, this initiative has led to the construction of a variety of infrastructures. The aim of this article is to identify the contribution made by the infrastructure built as part of the 11 December project to local development in the municipality of Ziniaré. The results of this research, based on fieldwork (direct observation in the field, a survey and semi-directive interviews) and enriched by documentary research, show that most of the planned projects have been successfully completed, in line with the guidelines of the Schéma Directeur d'Aménagement et d'Urba...

L'originalité de cet article réside dans la cible de l'étude, à savoir les enfants left behind, autrement dit, les enfants restés au pays d’origine des parents au moment de leur départ ou renvoyé dans ce pays après la migration de leurs parents biologiques. L'objectif est d'analyser les effets des transferts ou envois d’argent/ de fonds dans les ménages d'accueil des enfants restés au pays dans le corridor Burkina Faso - Côte d'Ivoire. Une enquête quantitative a été réalisée dans le cadre du projet MIDEQ (Migration pour le Développement et l'Égalité) couvrant quatre régions administratives et les deux plus grandes villes (Ouagadougou et Bobo-Dioulasso) du Burkina Faso. Ainsi, une analyse comparative à travers des statistiques descriptives et un modèle probit ont été utilisés pour mieux apprécier les effets des envois de fonds sur les ménages d’accueil des enfants restés au pays ou left b...

This paper addresses the lack of a comprehensive analysis of the ideological components of Donald J. Trump’s “Make America Great Again” (MAGA) slogan by examining how it served as a rhetorical tool to win the 2016 presidential election. In this paper we qualitatively and conceptually analyze Trump’s campaign materials from 2015–2016 using Cas Mudde’s populism (2004), Svetlana Boym’s restorative nostalgia (2001), and Rogers Brubaker’s exclusionary nationalism (1992). The obtained results demonstrate that Trump’s MAGA entailed a synthesis of three key elements: an exclusionary nationalism embodied in “America First” policies and America’s border strict control; a restorative nostalgia for an idealized post-WWII past to counter anxieties about deindustrialization and American demographic change; and a Manichean populist struggle between what Trump calls “forgotten Americans” and a corrup...

Rapid urbanisation in African cities has intensified pressures on urban mobility systems. In Ouagadougou, sustained population growth, urban sprawl, and rising travel demand continue to challenge the efficiency of urban transport despite ongoing investments in infrastructure and services. This study examines the institutional, organisational, and regulatory factors affecting urban mobility governance in the city. A mixed-methods approach was adopted, combining documentary review, questionnaire surveys administered to 300 stakeholders, semi-structured interviews, field observations, and SWOT analysis. Quantitative data were analysed using SPSS, while qualitative information was subjected to content analysis. The findings reveal that although multiple actors are involved in urban mobility governance, coordination remains weak. Most respondents considered existing coordination mechanisms in...

This study examines extreme precipitation trends across Burkina Faso’s Sahelian, Sudano-Sahelian, and Sudanian zones from 1991 to 2023, amid growing hydro-climatic variability in West Africa. The aim is to determine whether changes in rainfall extremes reflect gradual trends, structural shifts, or both. Three indices were analyzed: maximum 1-day precipitation (RX1day), maximum consecutive 5-day precipitation (RX5day), and the Simple Daily Intensity Index (SDII), using a non-parametric framework combining Mann – Kendall trends, Sen’s slope, and Pettitt change-point tests (p < 0.05), with spatial patterns mapped via GIS. Results show a latitudinal contrast. In the Sahelian zone, Dori recorded a significant SDII change in 2004 (p = 0.040) followed by increasing intensity. The Sudano-Sahelian zone exhibits the strongest signal: Ouagadougou shows upward trends in RX5day and SDII with a struct...
