COMPARATIVE STUDY OF 1-D AND 3-D MODELLING OF THE IMPACT OF MAGNETIC FIELD INTENSITY ON THE ELECTRICAL PERFORMANCE OF A BIFACIAL POLYCRYSTALLINE SILICON PV CELL
Idrissa Sourabié, Boubacar Soro, Alain Doua Gnabahou, Mahamadi Savadogo, Martial Zoungrana, Issa Zerbo
The aim of this work is to carry out a comparative study of the magnetic field effect of 1-D and 3-D modelling on a bifacial polycrystalline silicon solar cell under multispectral illumination from both sides. The continuity equations were solved in order to obtain the expressions for the various electron densities. The expressions for the car(...)

Pharmaceutical approaches for enhancing solubility and oral bioavailability of poorly soluble drugs
Isaïe Nyamba , Charles B Sombié, Moussa Yabré , Hermine Zimé-Diawara , Josias Yaméogo , Salfo Ouedraogo , Anna Lechanteur, Rasmané Semdé , Brigitte Evrard
High solubility in water and physiological fluids is an indispensable requirement for the pharmacological efficacy of an active pharmaceutical ingredient. Indeed, it is well established that pharmaceutical substances exhibiting limited solubility in water are inclined towards diminished and inconsistent absorption following oral administration(...)

CONSTRUCTION OF A CLASS OF COPULAS WITH HORIZONTAL OR VERTICAL SECTION OF A HOMOGRAPHIC FUNCTION
Herman Tiemtoré, Bagre Remi Guillaume, Loyara Vini Yves Bernadin
The construction of multivariate distributions with arbitrary margins has been a problem of interest to statisticians for many years, but nowadays, by virtue of Sklar’s theorem, this problem can be reduced to the construction of a copula. However, there is no general method for constructing a copula. In order to provide a partial solution to t(...)

Exploration of entomotherapeutic potential of bees’ products and termite nests from Burkina Faso
Mamadou Ouango, Hama Cissé, Rahim Romba, Samuel Fogné Drabo, Rasmané Semdé, Aly Savadogo, Olivier Gnankiné
In Burkina Faso, products and nests of insect are used for therapeutic purposes in traditional medicine. However, this
use by local populations is marginal and empirical. The objective of this study was to evaluate the antimicrobial activity of extracts of bees’ products and termite nests. Thus, the collected termite nests were finely ground.(...)

On exponential stability of mild solution of a stochastic integrodifferential equation in a complex Hilbert space
Wahabo BAGUIAN; Victorien KONANE; Claude YAMEOGO
In this work, we consider a system of stochastic integrodifferential
equations in a complex Hilbert space. We first establish the existence
and uniqueness of mild solutions for equation (1) under non-Lipschitz
conditions. Then we show under certain assumptions that the found
mild solution is exponentially stable on average of order n. Note(...)

Corrective Effect of the Angle of Incidence of the Magnetic Field Intensity on the Performance (Series and Shunt Resistances) of a Bifacial Silicon Solar Cell
Idrissa Sourabié, Mahamadi Savadogo, Boubacar Soro, Ramatou Saré, Christian Zoundi, Martial Zoungrana, Issa Zerbo
This article presents a three-dimensional analysis of the impact of the angle of incidence of the magnetic field intensity on the electrical performance (series resistance, shunt resistance) of a bifacial polycrystalline silicon solar cell. The cell is illuminated simultaneously from both sides. The continuity equation for the excess minority(...)

Dynamics of a SVEIR Epidemic Model with a Delay in Diagnosis in a Changing Environment
Hamadoum Dicko, Ali Traoré, Désiré Ouedraogo
SVEIR epidemic model with a delay in diagnosis is studied in a constant and variable environment. The mathematical analysis shows that the dynamics of the model in the constant environment are completely determined by the magnitude of the delay-induced reproduction number Rα. We established that if Rα<1, the disease-free equilibrium is globall(...)

Botanical, Physicochemical, and Phytochemical Studies of Zanthoxylum zanthoxyloides (Lam.) Zepernick and Timler (Rutaceae) Stem and Root Bark
Lassané Ouédraogo, Aminata Pagnimdebsom Nacoulma, Moussa Compaoré, Naamwin-So-Bawfu Romaric Meda, Vincent Rouamba, Martin Kiendrebeogo
Zanthoxylum zanthoxyloides, a medicinal plant overexploited in Burkina Faso due to the use of its roots for therapeutic purposes has been studied and it seems that the profile of the powder from stem and root bark are almost similar. This study aims to compare the botanical, physicochemical, and phytochemical parameters of Z. zanthoxyloides po(...)

Mapping Research on Bambara Groundnut (Vigna subterranea (L.) Verdc.) in Africa: Bibliometric, Geographical, and Topical Perspectives

While Bambara groundnut (Vigna subterranea (L.) Verdc.) originates from Africa and the list of producers is topped by African countries, it is not clear whether research is developed enough to support crop promotion in the continent. Thus, this systematic review of 180 articles presents a comprehensive summary of research on Bambara groundnut(...)

Caudal Appendage: About 3 Cases Report
KABRE Abel, HARO Yakouba, BAKO Itchizoun Frédéric, KIEMTORE Aminata, SANOU Abdoulaye, ZOUNGRANA Inoussa, ZABSONRE D. Sylvain
Introduction: A caudal appendix is a rare congenital malformation of the median or paramedian diverticulum type
located mainly in the lumbosacral region, of soft consistency, exceptionally provided with an axial skeleton and
covered with skin often of normal appearance and simulating a tail.
Patients: We report the cases of three female(...)

Déterminants la consommation de la chicha chez les adolescents et les jeunes à Ouagadougou au Burkina Faso
DRABO Alice Bougnan, ZOMA Vincent
L'adolescence et la jeunesse, périodes de recherche identitaire, expose souvent à des expériences risquées, telles que la pratique de la chicha de plus en plus populaire à Ouagadougou au Burkina Faso, si bien qu’une réglementation récente a interdit sa consommation dans cette ville soulevant ainsi des interrogations sur ses déterminants.

The Sahel is a region particularly characterized by undernutrition in several forms. In Burkina Faso, where several interventions have been carried out across the past several years, the nutritional situation of children under five years of age is still charac-terized by persistent stunting in the Est, Sahel, and Cascades regions. This study a(...)
