We present the impact of center-to-limb darkening (𝜀𝑖) on spectral line profiles of G-type stars through systematic analysis of cross-correlation function broadening. Using solar-type stellar spectra, we examine how center-to-limb darkening coefficients affect the measured full width at half maximum (FWHMCC) and derived rotational velocities (Vbroad). Our analysis employs the darkening coefficients from (Claret, 2000) and samples 19 rotational velocities from 0 to 100 km/s to optimize coverage of the observed stellar rotational ranges for calibration. We demonstrate that center- to-limb darkening variations induce systematic changes in measurements, with particularly pronounced effects for slow rotators where macroturbulence contributions (2-4 km/s) become dominant. The broadening parameter shows significant correlation with the darkening coefficient varying by 4.4 km/s (44.8%) over the...

Malgré la reconnaissance par tous que l’éducation est un droit de l’homme et un facteur essentiel au bien-être des individus et au développement économique des pays, les investissements dans ce secteur ne constituent pas une priorité pour les décideurs. Ce constat est visible au niveau post-primaire et secondaire où l’offre scolaire présente toujours des inégalités dans tous les domaines. Cette recherche analyse ces inégalités du point de vue de l’offre spatiale dans la ville de Koudougou l’une des quatre communes urbaines de la région du centre-ouest. Elle s’appuie sur une approche bidimensionnelle et utilise des données quantitatives et qualitatives primaires. La méthode d’analyse utilisée avec les données quantitatives est plus descriptive. Quant aux données qualitatives, c’est l’analyse du contenu qui est utilisée. Les résultats montrent que l’offre scolaire dans la ville de Koudougo...

La thématique du chaos est récurrente dans la production romanesque burkinabè. Depuis les premières heures, en 1962, avec la publication du roman Crépuscule des temps anciens, jusqu'à très récemment, en 2023. Si cette thématique semble illustrer les réalités de la société burkinabè, il est peut-être temps pour cette littérature d'amorcer un renouveau thématique.

This opinion paper is informed by a scoping review and validated through a multi-stakeholder workshop. In May 2024, the Gender Transformation for Africa, an African-led research partnership that includes programme implementers and researchers who are working on gender-transformative research projects to advance sexual and reproductive health (SRH) in Africa, convened a 3-day workshop in Cape Town, South Africa. The aim of the workshop was to validate a scoping review conducted by the School of Public Health at the University of the Western Cape. The scoping review aimed to examine patterns of leadership in authorship of gender-transformative SRH research and programming across Africa and focused on authorship, funding and geographic context. This review revealed significant regional disparities in the publication of gender-transformative SRH literature across Africa. Compared w...

Anemia is a public health problem afecting mainly children under 5 years and pregnant women. However, school-age children are also afected but are often neglected in research. This study aimed to assess the prevalence and factors associated with anemia among primary school children in public schools in the Plateau Central Region of Burkina Faso. Hemoglobin (Hb) concentration was determined using a HemoCue HB201þ analyzer. Data were collected from 551 schoolchildren aged 5–14 years. Anemia was established if the Hb level was lower than 11.5 g/dL in children aged 5–11 years and less than 12 g/dL in children aged 12–14 years. Binary logistic regression was adjusted to identify factors associated with anemia at a p value < 0.05. The prevalence of anemia was 59.2%, including 52.6% of the girls. Schoolchildren aged 5–11 years were the most afected, with a rate of 58.5%, versus 60.2% for...

Introduction: To assess anxiety and depressive disorders in patients with cirrhosis in the hepato-gastroenterology departments of two tertiary hospitals and one secondary hospital in the city of Ouagadougou. Patients and Methods: This was a descriptive and analytical cross-sectional study with prospective data collection. This study lasted five months and involved patients with cirrhosis. The diagnosis of cirrhosis was made on the basis of clinical and paraclinical criteria. Anxiety and depression were assessed using the HADS (Hospital Anxiety and Depression Scale) score. Results: A total of 90 patients were included. There were 70 men (77.8%). The mean age was 51.5 ± 26.5 years. Anxiety was observed in 48 patients (53.3%). Anxiety symptoms were evident in 35.5% of patients. Forty-two patients (46.7%) had depression. Depressive symptoms were evident in 30% of cases. Low socioeconomic...

Les Activités Physiques Sportives et Artistiques (APSA) de tradition sont des pratiques corporelles présentes dans toutes les communautés à travers les cultures au Burkina Faso. Etant donné que chaque culture a ses habitudes, sa manière d’éduquer le corps et l’esprit, la diversité culturelle du Burkina Faso liée à la multiplicité des groupes ethniques est en soit une richesse. Pour collecter ces données nous avons utilisé la méthode par questionnaire et l’entretien. Le logiciel IBM SPSS Statistics version 25, le logiciel Excel pour traiter les données obtenues du questionnaire, analyse de contenu a été utilisés pour des documents, de l’entretien et du focus group. Les résultats obtenus montrent une convergence des points de vue selon lesquelles les APSA de tradition remplissent des fonctions spécifiques et multiples allant de l’éducation à la sauvegarde de l’identité en passant par la fo...

Le débit de filtration glomérulaire (DFG) est le meilleur indicateur de la fonction rénale. En pratique clinique, il est le plus souvent estimé à partir d’équations dérivées de la créatininémie. L’objectif de notre étude était d’évaluer la performance de deux estimateurs du DFG en milieu hospitalier pédiatrique à Ouagadougou. Il s’agit d’une étude prospective menée du 1er octobre 2018 au 4 avril 2019 incluant les enfants âgés de 5 à 15 ans hospitalisés dans le service de pédiatrie médicale du CHU pédiatrique Charles-de-Gaulle. Le gold standard était la clairance de la créatinine calculée sur un recueil urinaire de 24 heures. Cent patients ont été inclus, avec un âge médian de 9 ans et un sex ratio de 1,5. La médiane de la clairance de la créatinine était de 79,69 mL/min/1,73 m2. Les médianes du DFG estimé par les formules de Schwartz-2009 et de Pottel étaient respectivement de 86,07 et...

The fine-grained felsic gneisses of the Léo region (southern Burkina Faso) constitute a key group of rocks for understanding the early evolution of the West African Craton. This study combines petrographic, geochemical, and geochronological (U–Pb on zircon) approaches to constrain their origin and geodynamic significance. Two main facies have been identified: (i) a strongly foliated and banded hornblende ± pyroxene granodioritic gneiss, and (ii) a biotite ± muscovite granitic gneiss, exhibiting remnants of magmatic texture. The petrographic and mineralogical characteristics, notably the dominance of quartz–feldspar–plagioclase assemblages, the absence of aluminosilicates, and their textural features, indicate a magmatic origin for the protoliths. Geochemical data show granitic to granodioritic compositions, metaluminous to slightly peraluminous, belonging to the Type I calc-alkaline s...

We present new petrographic and geochemical data for the Kapogouan area, located in the Banfora Belt in southwestern Burkina Faso. This study is based on an integrated approach combining petrographic and geochemical analysis of the various lithological units. The study area consists of a series of metavolcanic formations comprising metarhyolites, metadacites, metaandesites, and metabasalt, associated with sedimentary formations. These units are cut by various magmatic intrusions, including granites, granodiorites, monzonites, as well as vein bodies of doleritic and gabbroic composition. All of these formations are affected by a network of regional shear zones and by well-developed penetrating schistosity, reflecting polyphasic compressional tectonics. Regional metamorphism is generally of the green schist facies, with local transitions to the amphibolite facies near the intrusions, sugg...
