Prise en charge du VIH/sida et migrations internationales dans le district rural de Nanoro, Burkina Faso [HIV/AIDS care and international migrations in the rural district of Nanoro, Burkina Faso]
B. Autino, S. Odolini, H. Nitiema, D. Kiema, A. Melzani, V. Pietra, M. Martinetto, M. Bettinzoli, J. Simpore, G. Sulis, E. Focà, F. Castelli
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(...)

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(...)

Emergence of unusual G6P[6] rotaviruses in children, Burkina Faso, 2009-2010
Johan Nordgren, Leon W. Nitiema, Sumit Sharma, Djeneba Ouermi, Alfred S. Traore, Jacques Simpore, Lennart Svensson
To obtain more information about rotavirus (ROTAV) genotypes in Burkina Faso, we characterized 100 ROTAVs isolated from fecal samples of children with acute gastroenteritis in the capital city of Ouagadougou, during December 2009-March 2010. Of note, 13% of the ROTAV-positive samples, including those with mixed infections, were positive for th(...)

Calculation of air-water vapor mixtures thermal plasmas transport coefficients
A K Kagoné1, Z Koalaga1 and F Zougmoré1
Knowledge of transport coefficients of air-water vapor mixtures thermal plasmas is important to estimate the performances of electrical arc cutting in this gas by a circuit breaker.
In this paper, air-water vapor mixtures thermal plasmas dynamical viscosity, thermal and electrical conductivities coefficients are calculated in a temperature ra(...)

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(...)
