Propagation of Electromagnetic Wave into an Illuminated Polysilicon PV Cell
Vinci de Dieu Bokoyo Barandja, Bernard Zouma, Auguste Oscar Mackpayen, Martial Zoungrana, Issa Zerbo, and Dieudonné Joseph Bathiebo
The increasing cohabitation between telecommunication antennas generating electromagnetic waves and solar panels poses the problem of interaction between these radio waves and solar cells. In order to study the effect of radio waves on the performance of a polycrystalline silicon solar cell in a three-dimensional approach, it is necessary to a(...)

BILAN THERMIQUE QUASI-STATIQUE D'UN FOUR ARTISANAL EN ARGILE
D. BATHIEBO
On étudie les performances d'un four artisanal construit en argile compactée, utilisant des déchets végétaux comme combustible et permettant d'atteindre des températures supérieures à 1000 C. Le bilan thermique, objet de cette étude est obtenu en déterminant les transferts thermiques quasi-statiques lors de la cuisson de canaris. On atteint un(...)

Characterization of a natural laterite of Burkina Faso for the elimination of arsenic (III) and arsenic (V) in ground water
Régie Dimanche OUEDRAOGO, Corneille BAKOUAN, Brahima Sorgho, Boubié Guel, Lucien BONOU .
Arsenic is one of the major pollutants in borehole water and is an international concern because of its adverse effects on human health. In this study, a lateritic material was used for the removal of arsenic (III) and arsenic (V) in aqueous solution. The laterite used is referenced DA and characterized by different physico-chemical methods (D(...)

Multi-scale analysis of runoff from a statistical perspective in a small Sahelian catchment under semiarid climate.
Lawani Adjadi Mounirou, Cheick Oumar Zouré, Roland Yonaba, Jean- Emmanuel Paturel, Gil Mahé, Dial Niang, Hamma Yacouba, Harouna Karambiri
In Sahelian and semi-arid regions, understanding the runoff processes and at different spatial scales is critical to assess sources of variation and further improve distributed modelling. In this study, through a multi-scale analysis, runoff measurements on different soil surface features and at different scales of observation were carried ove(...)

Comparative study of three ways of using Jatropha curcas vegetable oil in a direct injection diesel engine
Sayon Sidibe, Joel Blin, Tizane Daho, Gilles Vaitilingom , Jean Koulidiati.
Although vegetable oils are apparently an advantageous alternative fuel for direct use in
traditional diesel engines with no modification necessary, in practice many problems are
regularly discussed in the literature including filter clogging, breakage of certain types of
injection pumps, and deposits of carbon on the cold parts of engines.(...)

Trees in African drylands can promote deep soil and groundwater recharge in a future climate with more intense rainfall
Aida Bargués‐Tobella, Niles J Hasselquist, Hugues R Bazié, Jules Bayala, Hjalmar Laudon, Ulrik Ilstedt
Tropical regions are likely to experience more intense rainfall events in the future.
Such an increase in rainfall intensities will affect soil and groundwater recharge, with
potential consequences for millions of people. However, little is known about the
impact of tree cover on soil and groundwater recharge under higher rainfall intensiti(...)

Existence of solutions for some nonautonomous partial functional differential equations with state-dependent delay
Moussa El-KhalilL Kpoumie, Abdel Hamid Gamal Nsangou, Patrice Ndambomve, Issa Zabsonre and Salifou Mboutngam
The aim of this work is to prove the existence of mild solutions for some nondensely nonautonomous partial functional diferential equations with state-dependent delay in Banach spaces. We assume that the linear part is not necessarily densely deined and generates an evolution family. Our approach is based on a nonlinear alternative of Leray-Sc(...)

Role of microRNA-33a/b in Cholesterol Metabolism in Type 2 Diabetic Patients in Ouagadougou, Burkina Faso
Alice Kiba Koumaré, Tegwinde Rebeca Compaoré, Fabienne Soudré, Raoul Karfo, Gnabôrou Rachid Konfé, Elie Kabré, Ignatius Baldeh, Jacques Simporé, Jean Sakandé.
Abstract: MicroRNAs (miRNAs) are small endogenous RNAs approximately 22 nucleotides involved in the regulation of several cellular metabolisms including cholesterol metabolism. The objective of this study was to measure miRNAs 33a and 33b in type 2 diabetics to evaluate their impact on the lipids levels and prevalence of dyslipidemia. The stud(...)

Physicochemical and microbiological quality and acceptability of six formulations of Saba senegalensis pulp nectar
Leguet GANOU, Clarisse S. COMPAORE, Salamata TIENDREBEOGO, Fidèle W. TAPSOBA, Mamoudou H. DICKO
The fruits of Saba senegalensis are consumed in Burkina Faso in various forms. In the present study, six formulations of nectar from S. senegalensis pulp were produced based on a general diagram. The physicochemical, microbiological and organoleptic characteristics of these formulations were then determined using standardized methods. The resu(...)

Boosting land restoration success in the Great Green Wall through the use of symbiotic microorganisms for propagated tree seedlings.
FOFANA Barkissa, SACANDE Moctar, BLAGNA Fanta, DIBLONI O. Théophile, COMPAORE Emmanuel, SANON B. Kadidia, MAIGA Ynoussa,OUATTARA S. Aboubakar
Several studies have clearly demonstrated the scientific and practical use of the symbiotics
microorganisms for plants in earth ecosystems. The main goal of this study was to rehabilitate a degraded soil
of the sahelian zone of Burkina Faso by using the rhizobia and mycorrhizal symbiosis through the inoculation
technique. Native rhizobia(...)

Anti-inflammatory and antioxidant activities of a fraction I1 of male inflorescences of Borassus aethiopum Mart (Arecaceae)
E. KABRE
In previous studies, using a bioassay-guided fractionation procedure; five fractions (E1F1, E2F2, E3F3, E4F4 and E5F5) from powdered Borassus aethiopum male inflorescences were extracted. Among these, the dichloromethane methanol extract E2F2 was found to exert significant anti-inflammatory and antipyretic activities and pro apoptotic effect.(...)

This work is an extension of a previous publication. An optimal control
theory is applied to a model of malaria transmission dynamics to investigate
the control strategies for eliminating malaria using time dependent controls.
Four main efforts are considered including the treatment of infected humans,
the individual protection, vectors co(...)

Estimation of the Value at Risk Using the Stochastic Approach of Taylor Formula
Vini Yves Bernadin Loyara; Remi Guillaume Bagré; Diakarya Barro
The aim of this paper is to provide an approximation of the value-at-risk of the multivariate copula associated with financial loss and profit function. A higher dimensional extension of the Taylor–Young formula is used for this estimation in a Euclidean space. Moreover, a time-varying and conditional copula is used for the modeling of the VaR(...)
