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(...)

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).(...)

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.
generalised Lebesgue-Sobolev spaces, weak solution, bounded Radon measure, p(x)-Laplace operator, electrorheological fluids, Marcinkiewicz spaces

Influence de l’épaisseur de la couche tampon et de la température sur les propriétés d’une photopile en couches minces à base de CIGS.
Marcel B. KEBRE, François ZOUGMORE, Daouda OUBDA, Soumaila OUEDRAOGO, Zacharie KOALAGA.
Dans ce travail, nous utilisons le logiciel de simulation SCAPS-1D pour l’optimisation des performances d’une cellule
solaire de type Mo/Cu(In,Ga)Se2/CdS/ZnO/. Plus particulièrement nous nous intéressons à l’influence de l’épaisseur de la
couche tampon CdS et de la température extérieure sur les performances électriques et énergétiques de la(...)

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

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(...)

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(...)

Essai de production de protéines d’organismes unicellulaires par des souches de levures à partir de résidus de tubercules de patate douce et d’igname
Nicolas Ouédraogo, Aly Savadogo, Marius K. Somda, Cheikna Zongo, Alfred S.Traore
Cette étude décrit l’utilisation des résidus de tubercules de patate douce et d’igname comme substrat pour la production de protéines d’organismes unicellulaires au Burkina Faso. Deux souches de Saccharomyces cerevisiae et d eux de Candida utilis ont été utilisées. Ces souches ont été sélectionnées en fonction de leur vitesse de croissance par(...)

High performance amylolytic yeast strains isolation and identification for valorization of potatoes waste available in Burkina Faso
Ouédraogo N., Savadogo A., Zongo C., Somda K. M. and Traoré A. S.
This study deals with isolation and identification of high amylolytic activity strains from potato wastes for biomass production. A total of twenty five (25) yeast strains were isolated using standard microbiological methods. Ten (10) strains were retained on the basis of their capacity to hydrolyze starch. Identification to species level of s(...)

Classification of traces and associated determinants on odd-class operators in odd dimensions
Carolina Neira Jiménez, Marie Françoise Ouedraogo
To supplement the already known classification of traces on classical pseu-dodifferential operators, we present a classification of traces on the algebras of odd-class pseudodifferential operators of non-positive order acting on smooth functions on a closed odd-dimensional manifold. By means of the one to one correspondence between continuous(...)

Essential Oils in Combination and Their Antimicrobial Properties
Imaël Henri Nestor Bassolé , * and H. Rodolfo Juliani
Essential oils (EOs) have been long recognized for their antibacterial, antifungal, antiviral, insecticidal and antioxidant properties. They are widely used in medicine and the food industry for these purposes. The increased interest in alternative natural substances is driving the research community to(...)
