DESIGN OPTO-MÉCANIQUE D’UN INSTRUMENT VERSATILE POUR L’OBSERVATOIRE D’ASTROPHYSIQUE AU BURKINA
KAM Sié Zacharie, Bado Fabrice, Badolo Aymard, KOULIDIATI Jean, Béré Antoine
Les observations astronomiques sont basées sur l’exploitation d’instruments, qui sont de plus en plus robustes et extrêmement performant. La qualité des observations n’est pas seulement le fruit de l’instrument mais aussi du site choisi. Nous présentons dans un cette communication le design d’un instrument astronomique destiné à des observatio(...)

DÉTERMINATION DES VITESSES DE ROTATION DES ÉTOILES DE TYPE FGK DANS LE CADRE DU PROJET AMBRE
BADO Fabrice, KAM Sié Zacharie, De LAVERNY Patrick, BADOLO Nekolgne Aymard, KOULIDIATI Jean
Il n’y a à l’heure actuelle très peu de catalogues de vitesse de rotation (Vsini) pour les étoiles FGK et leurs propriétés de rotation sont encore mal connues. Le but est de créer un catalogue de Vsini pour plusieurs milliers d’étoiles FGK à partir de spectres haute résolution collectés au sol dans le cadre du projet AMBRE. Dans un premier tem(...)

ÉTUDE PROSPECTIVE DES PHÉNOMÈNES DE TRANSFERT RADIATIF DANS LES ÉTOILES POST-SÉQUENCE PRINCIPALE : CAS DE HD 30856 (MOUHOUN)
ZOUNGRANA André, KAM Sié Zacharie
Après son parcourt sur la séquence principale du diagramme Hertzsprung-Russell (HR), où dans son cœur de l’hydrogène est brulé en hélium, il s’ensuit, pour une étoile, la possible fusion de l’hélium, du carbone, et d’éléments plus lourds, qui par la suite, forment une enveloppe poussiéreuse autour de l’étoile. Nous étudions dans cet article le(...)

Salam Sawadogo, Koumpingnin Nebie, Catherine Traore, Abdoul-Guayini Sawadogo, Donatien Kima, Malick Nabaloum, Eric Arnaud Diendéré, Henri Gautier Ouedraogo, Eléonore Kafando, Yéri Esther Hien
Introduction: Like all countries in the world, sub-Saharan Africa has been affected by the COVID-19 pandemic. The socioeconomic impact of the crisis has affected the health system, pushing certain health priorities into the background. In sub-Saharan Africa, the disease remains a major problem, with the highest incidence and lethality.

Investigating EFL Teachers’ Vocabulary Teaching Practices through Reading
Lassina Soma, F. Emilie G. Sanon/Ouattara
The present study elaborates on how EFL teachers deal with unknown/unfamiliar words in reading comprehension. It involves sixtynine (69) EFL teachers selected through the snowballing sampling technique. As a result, the study endeavours to answer the research question ‘How familiar are EFL teachers with contextual clues used in reading compreh(...)

Multiple solutions of a discrete nonlinear boundary value problem involving p(k)-Laplace Kirchhoff type operator
Moussa Brahim, Nyanquini Ismaël, Ouaro Stanislas
In this article, we prove the existence of at least one or two nontrivial solutions of a discrete nonlinear boundary value problem of p(k)-Laplace Kirchhoff type in a finite dimensional Banach space. Our approach is based on variational methods and on critical point theory.

Evaluation of the SD Bioline Syphilis 3.0 rapid immunochromatographic test for syphilis screening in Burkina Fas
Oumar TRAORÉ, Dissinviel Stéphane KPODA, Adama Patrice SOUBEIGA, Rokiatou Henry-SANGARÉ , Abraham AJAYI , Casimir OUÉDRAOGO, Maxime Koiné DRABO, Elie KABRÉ, Lassana SANGARÉ
Syphilis remains a global health problem. In Burkina Faso, cases of syphilis are still prevalent despite
concerted effort in the fight against sexually transmitted infections. The availability of Treponema pallidum
haemagglutination assay in the diagnosis of syphilis has not eliminated the challenges encountered in the
diagnosis of syphil(...)

Disk Galaxies Are Self-similar: The Universality of the HI- to-Halo Mass Ratio for Isolated Disks
Marie Korsaga, Benoit Famaey, Jonathan Freundlich, Lorenzo Posti, Rodrigo Ibata, Christian Boily, Katarina Kraljic, E. Esparza-Arredondo, C. Ramos Almeida, Jean Koulidiati
Observed scaling relations in galaxies between baryons and dark matter global properties are key to shed light on the process of galaxy formation and on the nature of dark matter. Here, we study the scaling relation between the neutral hydrogen (HI) and dark matter mass in isolated rotationally supported disk galaxies at low redshift. We first(...)

Introduction : La drépanocytose est un problème de santé publique. Elle entraîne des complications aigues à type de crises vaso-occlusives, d'infections et d'hémolyse. Sa prise en charge nécessite des transfusions sanguines itératives dont la qualité et la sécurité ne sont pas toujours garanties dans notre contexte. Notre étude visait à décrir(...)

Early alert of an outbreak based on event detection and tracking on social networks: The case of Covid-19 and meningitis
Julie Thiombiano; Yaya Traore; Sadouanouan Malo
In this paper, we propose an early warning approach for the occurrence of meningitis or Covid-19 epidemics based on the analysis of Twitter messages (tweets). To achieve this, we initially employed automatic classification techniques using Natural Language Processing and domain ontologies to filter the tweets. Subsequently, we utilized the met(...)

Ethnobotany and conservation of the species Celtis toka (Forssk.) Hepper & J.R.I. wood: A way forward for sustainable use in Burkina Faso
Zaïnabou Dabré, Issouf Zerbo, Blandine Marie Ivette Nacoulma, Dodiomon Soro, Adjima Thiombiano
Celtis toka (C. toka), a critically endangered mystical plant, is a highly valued and overharvested multiuse tree species by local population in Burkina Faso. The ethnobotany of C. toka can lead to its sustainable use, therefore it is a great challenge because little information is available on this aspect concerning the species in Burkina Fas(...)

Aminata Sanou, François Tapsoba, Jeanne d’Arc Wendmintiri Kabré, Sanogo Bougma, Mah Alima Esther Traoré, Prudence Dounia, Charles Parkouda, Aly Savadogo
Nutritional studies make little reference to essential amino acids to explain undernutrition in protein-energy malnutrition. This study aimed to carry out biochemical characterization and amino acid profiling of Detarium microcarpum and Adansonia digitata fruit pulps and Moringa oleifera leaf powder to show their contribution to protein balanc(...)
