Lyophilized powders of decocts of Lannea microcarpa have scientifically proven their efficacy and safety to treatment of arterial hypertension. However, these powders are very hygroscopic, with poor physicomechanical properties that cannot be used directly in capsules. Objective was to develop a capsule dosage form containing Lannea microcarpa(...)

3-D MODELLING OF ELECTRICAL PARAMETERS’ EFFECTS ON THE HEATING OF THE BASE OF AN INTENSE LIGHT ILLUMINATED POLYCRYSTALLINE SILICON PV CELL
B. Soro, M. Savadogo, B. Zouma, K. E. Tchedre, I. Sourabie, I. Zerbo, M. Zoungrana, D. J. Bathiebo
Performances of a solar cell are significantly influenced by the heating of the base. Two phenomena contribute to the heating of the base of a PV cell: the heat due to the transfer by conduction of the solar energy radiation received by the surface of the PV cell and the heat generated inside the solar cell by various phenomena related to the(...)

Ameloblastic fibroma (AF) is a rare mixed odontogenic benign tumor with mesenchymal and epithelial components.
It occurs mostly in young subjects with a male predominance (average age 15 years) and a predominant
mandibular location. It is diagnosed histologically and treated surgically. The postoperative evolution is favorable

STOCHASTIC INCREASE IN CDS AND CDO PORTFOLIO PREMIUMS
Vini Yves Bernadin Loyara, Remi Guillaume Bagré, Frédéric Béré and Diakarya Barro
This paper deals with the family of nested Archimedean copulas in sampling financial risk factors. We propose the fourth and fifth orders of extensions of nested Archimedean copulas. Some tests of simulations on the functional are made for the risk factors. The CDS portfolio and discount factors are clarified while the cash portion of annualiz(...)

Structural stability of nonlinear elliptic p(u)-Laplacian problem with Robin type boundary condition
S. Ouaro, N; Sawadogo
We study in this chapter the following nonlinear elliptic boundary value problem,
b(u)−diva(x,u,∇u)=fin Ω,a(x,u,∇u).η=−|u|r(x,u)−2uon ∂Ω,
where Ω is a bounded open domain in ℝN, N≥3, with smooth boundary ∂Ω. We prove the existence and uniqueness of weak solution for f∈L1(Ω) and structural stability result.
