Contrastive analysis: A valid concept in the 21st century?
DJIGUIMKOUDRE Nathalie
Dans cet article, le concept « analyse contrastive » a été examiné des origines à nos jours. L’analyse contrastive a été utilisée dans les années 50 comme la meilleure approche dans l’enseignement des langues secondes ou étrangères (Lado 1957). Ainsi dit, les enseignants des langues secondes et étrangères avaient pour mission de comparer la(...)

Marqueurs biologiques non virologiques pour le diagnostic et le suivi
Soudré FM, Sakandé J.
Une hépatite virale se définit comme tout processus inflammatoire du foie causée par
un virus. Il existe principalement cinq virus hépatotropes : A, B, C, D et E. Les pathologies
hépatiques, aigües ou chroniques, sont extrêmement fréquentes. Leur diagnostic, la recherche
étiologique, le suivi de la pathologie et le suivi thérapeutique néces(...)

Profil lipidique au cours de l’hépatite B chronique à Ouagadougou (Burkina Faso)
Kiba Koumaré A, Soudré F, Kouraogo GA, Kinda O, Karfo R, Kabré E, Sakandé J
Introduction : L’infection au VHB a été associée à des perturbations du métabolisme lipidiques mais le sens de ces
perturbations n’est pas encore clairement établi. Dans cette étude, nous avons évalué le profil lipidique des patients porteurs chroniques du VHB au Burkina Faso.
Matériel et Méthodes : Des échantillons de sang veineux ont été(...)

THEORETICAL AND EXPERIMENTAL ANALYSIS OF A BOOST CONVERTER
Badiane Modou, Honadia Prince Abdoul Aziz, Barro Fabé Idrissa
A theoretical and experimental study of a conventional boost converter is presented. Based on the real behavior of the components, the conventional boost converter model dealing with both inductive and capacitive losses as well as switching losses is introduced. From this model, the detailed analytical expressions of the voltage gain factor a(...)

Formulation of clay refractory bricks: influence of the nature of chamotte and the alumina content in the clay
Moustapha Sawadogo, Mohamed Seynou, Lamine Zerbo, Brahima Sorgho, Gisèle Laure Lecomte-Nana, Philippe Blanchart, Raguilnaba Ouédraogo
Abstract: Refractory materials from kaolinitic clays and clay chamotte or quartz were studied to increase the refractoriness
under load at temperature above 1300°C. Two different clays mined in Burkina Faso were used and chamotte grains were
obtained by preliminary firing a local clay. Fired materials at 1350-1400°C present a typical granu(...)
