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(...)

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(...)

Elaboration d’une année météorologique type de la ville de Ouagadougou pour l’étude des performances énergétiques des bâtiments
E. Ouedraogo , O. Coulibaly et A. Ouedraogo
Dans cette étude, nous utilisons deux (02) méthodes de génération pour élaborer cinq (05) années types de sorte à déterminer la plus performante ou représentative. Ces années sont générées en utilisant des données de la température de l’air, de l’humidité relative de l’air, de la vitesse du vent et du rayonnement solaire(...)

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(...)

Guiera senegalensis is a well known medicinal plant which is used as a drug in Burkina Faso. The purpose of the present study was to investigate the carotenoids content and antibacterial activity from galls of Guiera senegalensis. The hydroacetonic extract (HAE) exhibited the highest of β-carotene (4.67±0.25 mg/g) and lycopene (0.99±0.0735 mg/(...)
