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(...)

Abstract. The specific germs that cause chronic otitis media determine the treatment necessary. The purpose of this study was to identify the pathogens involved in this disease and to determine the sensitivity of the antibiotics commonly used in order to improve treatment. Methods: This prospective study took place over 12 months and recorde(...)

On the solvability of discrete nonlinear two-point boundary value problems

B. Koné, S. Ouaro

We prove the existence and uniqueness of solutions for a family of discrete boundary value problems by using a discrete Wirtinger inequality. The boundary condition is a combination of Dirichlet and Neumann boundary conditions

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/(...)

Separating competition-related factors limiting crop performance in an agroforestry parkland system in Burkina Faso

H. BAZIE

To address tree–soil–crop interactions in the Sahel, we examined the growth-limiting factors (water, light and mineral nutrients) of Sorghum bicolor growing under trees in agroforestry parklands of Burkina Faso. Growth and yields of sorghum were measured after (1) pruning crowns of Vitellaria paradoxa and Parkia biglobosa trees, and (2) applyi(...)

Phytochemistry and Biological Activities of Extracts from Two Combretaceae Found in Burkina Faso: Anogeissus Leiocarpus (DC) Guill. and Perr. And Combretum Gl...

SORE H., HILOU A., SOMBIE Pierre A. E. D., COMPAORE M., MEDA R., MILLOGO J. and NACOULMA O. G.

Many studies indicate that Combretaceae species are commonly used in Africa to treat various diseases. Nonetheless, no phytochemical and/or biological activity data are available from species found in Burkina Faso to secure their ethnomedicinal uses. In addition, drugs derived from these species, especially those of the genus Combretum, are so(...)
