Profile: the Ouagadougou health and demographic surveillance system

B. SOURA

Summary The Ouagadougou Health and Demographic Surveillance System (Ouaga HDSS), located in five neighbourhoods at the northern periphery of the capital of Burkina Faso, was established in 2008. Data on vital events (births, deaths, unions, migration events) are collected during household visits that have taken place every 10 months. The areas(...)

Antioxidant, xanthine oxidase and lipoxygenase inhibitory activities and phenolics of Bauhinia rufescens Lam.(Caesalpiniaceae)

M. COMPAORE et al.,

An aqueous acetone extract of the stem with the leaves of Bauhinia rufescens and its fractions were analysed for their antioxidant and enzyme-inhibitory activities, as well as their phytochemical composition. For measurement of the antioxidant activities, the 2, 2-diphenyl-1-picrylhydrazyl, 2, 2′-azinobis (3-ethylbenzoline-6-sulphonate) and th(...)

Reductive and oxidative combustion of polyethylene bags : characterization of carbonaceous and nitrogenous species

Salifou K. Ouiminga, Thomas Rogaume, Tizane Daho, Arsène H. Yonli, Jean Koulidiati

This study aims to experimentally characterize the gaseous carbonaceous and nitrogenous species from the reductive and oxidant combustion of polyethylene plastic bags. The experimental device used is the tubular furnace, coupled to two gas analyzers: a Fourier transform infrared analyzer (FTIR) and a non dispersive infrared analyzer (NDIR). Th(...)

Weak solutions for some nonlinear elliptic problem with variable exponent and measure data

Stanislas Ouaro and Safimba Soma

We prove the existence of weak solutions to nonlinear elliptic equations with variable exponent and measure data. The functional setting involves Lebesgue-Sobolev spaces with variable exponent and Marcinkiewicz spaces.

Modélisation numérique d’une cellule solaire en couches minces à base de CIGS et une couche tampon alternative graduée.

Marcel B. KEBRE, François ZOUGMORE, Soumaila OUEDRAOGO, Raguilignaba SAM, Zacharie KOALAGA.

Une étude comparative des caractéristiques électriques et énergétiques ont été faite entre les photopiles CdS/CIGS, ZnO/CIGS et ZnS/CIGS en utilisant SCAPS-1D. La cellule solaire en couches minces CIGS sans cadmium est de type Mo/CuIn0.7Ga0.3Se2/ZnO1-xSx/OTC. L’étude approfondie de la couche tampon alternative ZnO1-xSx, montre qu’une concen(...)

West African Countries account for almost half of the estimated 20 000 000 international migrants in the continent. In the frame of the scaling up of HAART, our study aims to identify specific features and constraints of access to care for HIV migrant patients returning to Burkina Faso. From January 2007 to August 2011, the Nanoro District Hos(...)

Contribution to the design of a pottery kiln using as fuel a mixture of cellulosic and plastic materials : influence of the proportion of plastic on the emissions of NO, CO2, O2

Salifou K. Ouiminga1*, Thomas Rogaume2, Alfa Oumar Dissa1, Samuel Ouoba1, Tizane Daho1 , Jean Koulidiati1

This paper concerns the study of the influence of the proportion of plastic from polyethylene, on the yields of gas emissions during the combustion of the mixture of “millet stalks and polyethylene plastic bags”, in a prototype of kiln of potters. During these investigations, we looked at the rate of residual oxygen (O2) and emissions of carbo(...)

Entropy solution to an elliptic problem with nonlinear boundary conditions

S. Ouaro, A. Ouédraogo

We consider the equation b(u)−diva(u,Du)=f in a bounded domain with nonlinear boundary conditions of the form −a(u,Du)⋅η∈β(x,u). We introduce a notion of entropy solution for this problem and prove existence and uniqueness of this solution for general L1-data

Targeting Structural Motifs of Flavonoid Diglycosides Using Collision-Induced Dissociation Experiments on Flavonoid/Pb2+ Complexes

Ousmane Ilboudo, Issa Tapsoba, Yvonne L. Bonzi-Coulibaly, Pascal Gerbaux

Differentiation of flavonoid congeners remains a challenging analytical problem and confirming the structures of the different isomers is difficult, even when they can be adequately separated from mixtures. In the present report, in order to overcome the limits of our recently proposed method that relies on the distinctive CID behaviors of [(f(...)
