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(...)

Prevalence of HBV and HCV markers among patients attending the Saint Camille Medical Centre in Ouagadougou.
MT Zeba, CA Ouattara, SD Karou, C Bisseye, D Ouermi, FW Djigma, T Sagna, V Pietra, R Moret, J Nikiema, J Simpore
HCV and HBV cause annually, 2000 deaths from liver cancer in Burkina Faso. In this country, serological screening of hepatitis viruses B and C is only systematic among blood donors. The aims of this study were; (1) to investigate the reasons for the prescription of the screening for hepatitis B and C; (2) to determine HCV and HBV prevalence am(...)

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(...)

Entropy solution for nonlinear elliptic problem involving variable exponent and Fourier type boundary condition
I. Nyanquini, S. Ouaro
In this work, we study the following nonlinear non-homogeneous Fourier boundary value problem b(u)−div(a(x,∇u))=f in Ω, a(x,∇u)⋅η+λu=g on ∂Ω, where Ω is a smooth bounded open domain in ℝN, N≥3, p∈C(Ω). We prove the existence and uniqueness of a weak solution for f∈L∞(Ω) and g∈L∞(∂Ω), the existence and uniqueness of an entropy solution for L1-d(...)

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(...)

T. Daho, G. Vaitilingom, O. Sanogo, S. K. Ouiminga, B.G. Segda, J. Valette, P. Higelin, J. Koulidiati
In this work, a model for predicting evaporation characteristics (constant of evaporation and evaporation time) of cottonseed oil and diesel fuel has been developed and validated experimentally in the temper- ature range of 684–917 K under atmospheric pressure. The experimental study is based on the fibre-suspended droplet evaporation techniqu(...)
