Performance Study of a Quadratic Boost Converter
Modou Badiane, Prince Abdoul Aziz Honadia, Oumar Diallo Sadio, Fabé Idrissa Barro
Energy is the driving force behind all economic and industrial development. Africa is the least advanced continent in terms of energy consumption and production. Paradoxically, it is the sunniest continent, which is why our objective is to exploit this energy potential in order to produce and use sufficient energy. To achieve this, we are carr(...)

Regard sur l’évolution des inégalités sociales et de la violence au Burkina Faso (1990 à 2014)
Millogo Missa, Nacoulma Jean
Cette réflexion traite de la vie sociopolitique du Burkina Faso. L’espace sociopolitique, depuis la décennie 1990, est marqué par des politiques libérales, une gouvernance officiellement démocratique sous la direction du régime du président Blaise Compaoré. Il est aussi caractérisé, de plus en plus, par une évolution des inégalités sociales(...)

Cost-Effective Monitoring of the Fuel Air Equivalence-Ratio with a Lambda Sensor and a Microcontroller in a Downdraft Biomass Gasifier
Jean Fidele Nzihou, Salou Hamidou, Ousmane Zoundi, Frederic Ouattara, Bila Gerard Segda
The operation of biomass treatment devices such as gasifiers is based on the
control of key parameters that play an important role in product formation.
These include: temperature, excess oxygen, relative humidity and biomass
composition. This work focuses on excess oxygen and temperature. Unfortunately, flue gas oxygen analyzers are ex(...)

ON 3D COMPRESSIBLE PRIMITIVE EQUATIONS APPROXIMATION OF ANISOTROPIC NAVIER-STOKES EQUATIONS: RIGOROUS JUSTIFICATION
Jules Ouya , Arouna Ouédraogo
In this paper, we obtain the 3D compressible primitive equations approximation without gravity by taking the small aspect ratio limit to the Navier-Stokes equations in the isothermal case with gravity. The aspect ratio (the ratio of the depth to horizontal width) is a geometrical constraint in general large scale geophysical motions that the v(...)

Défis de la prise en charge de la fistule oesotrachéale sur terrain immunodéprimé à Bobo-Dioulasso (Burkina Faso) : à propos d’un cas
M ZouréE, M Koura, NA Guingané, BE Kamboulé, AG Ouédraogo, D Napon-Zongo, A Sawadogo
La fistule oesotrachéale est une affection rare qui compliquer les affections opportunistes sur terrain immunodéprimé par le VIH. L’évolution peut être fatale dans notre contexte caractérisé par un plateau technique déficient. Nous rapportons un cas de fistule oesotrachéale chez un patient de 48 ans immunodéprimé par le VIH. Le diagnostic a ét(...)

Study of The Influence of Storage Media on the Thermo-mechanical Behavior of Concrete and Cement Blocks
Benjamin Kiema , Ousmane Coulibaly and Emmanuel Ouedraogo
Once all construction materials have been formulated, it is necessary to find a suitable environment in which to store them before using them in the building. Generally speaking, in developing countries, materials are not preserved under the real conditions of temperature and humidity and are exposed to often severe climatic conditions. This h(...)

Mapping the incidence rate of typhoid fever in sub-Saharan Africa
Kim JH, Choi J, Kim C, Pak GD, Parajulee P, Haselbeck A, Park SE, Mogasale V, Jeon HJ, Browne AJ, Owusu-Dabo E, Rakotozandrindrainy R, Bassiahi A Soura, Teferi M, Lunguya-Metila O, Dolecek C, Pitzer VE, Crump JA, Hay SI, Marks F.
Typhoid fever remains a significant health challenge in low- and middle-income nations, especially in sub-Saharan Africa. A comprehensive understanding of the disease’s geospatial distribution is pivotal for its control—a gap previous studies overlooked. Addressing this, we undertook a study to chart the incidence of typhoid fever throughout s(...)

Hydrochemical Characterisation of Groundwaters in a Crystalline Basement Environment: The Case of Fractured Aquifers in the Poni Watershed in the South-West Region of Burkina Faso, West Africa
Hebie, A., Kafando, S., & Nakolendousse, S
The Poni watershed is located in the south-west of Burkina Faso. Its geology is made up of fractured crystalline and crystallophyllian basement, where fractured aquifers are the most exploited for water needs. The aim of this study is to determine the physico-chemical characteristics of the groundwater in the fractured aquifers of the Poni wat(...)

Goitre Historique Compressif Plongeant : À Propos d’un Cas
Gyebre YMC, Zaghre N, Kaba M.K., Bargo C.R, Bambara C.N., Nao E.E.M, Sereme M, Ouedraogo B.P
Le goitre nodulaire est un problème de santé publique. En effet 5 à 10% de la
population mondiale présente un nodule thyroïdien palpable. Il peut évoluer
vers un goitre multi nodulaire compressif et plongeant constituant une urgence
par asphyxie. Nous rapportons le cas d’un patient de 69 ans venu consulter
pour une dyspnée laryngée sur un(...)
