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(...)

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(...)

Model for predicting evaporation characteristics of vegetable oils droplets based on their fatty acid composition
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/(...)

Dynamique et stratégies de conservation de la végétation et de la phytodiversité du complexe écologique du parc national du W du Burkina Faso
Blandine Marie Ivette NACOULMA
Dans les régions tropicales, les populations dépendent étroitement des écosystèmes de savanes pour leur subsistance. Cependant, dans ces dernières décennies, les savanes ouest- africaines sont sujettes à des changements d’utilisation des terres consécutifs à la pression démographique et à l’intérêt grandissant accordé aux cultur(...)
