Weak and entropy solutions to nonlinear elliptic problems with variable exponent.
S. Ouaro, S. Traoré
The authors study nonlinear boundary value problem with the nonlinear operator of p-Laplacian-type and Dirichlet boundary condition. The authors obtain two existence results: in first a unique entropy solution is obtain and in the second a week solution is produced.

INFANT FEEDING MODALITIES AND MORBIDITY IN HIV INFECTED WOMEN IN RESOURCE-POOR COUNTRIES. A MULTICENTER STUDY IN SUBSAHARAN AFRICA
L. R. Tomasoni, M. Galli, V. Vullo, B. Pedruzzi, V. Pietra, J. Simporé, E. Gianelli, S. Rusconi, A. Riva, Giovanni Guaraldi, K. Luzi, G. Russo, M. Lichtner, G. Carosi, F. Castelli
The optimal feeding modality of infants born to HIV infected mothers in resource-limited settings is still the subject for debate. WHO guidelines recommends exclusive formula feeding wherever it is available, feasible, affordable, safe and sustainable (AFASS). In all other instances, exclusive breastfeeding and early weaning is recommended. Ho(...)

Toward a Better Representation of Women in Physics in Burkina Faso
P. Kafando, M.N.Sido-Pabyam, and I. Zerbo
Although 52% of Burkina Faso's population is women, boys receive preference in schooling. In 2006, only about 10% of the secondary school pupils were girls. At the University of Ouagadougou in 2000-2005 one quarter of the students were women, but just 5% of students in the sciences were women. This rate is dramatically lower in physics, both f(...)

Uniqueness of entropy solutions of nonlinear elliptic-parabolic-hyperbolic problems in one dimension space.
S. Ouaro
We consider a class of elliptic-parabolic-hyperbolic degenerate equations of the form b(u)t−a(u,φ(u)x)x=f with homogeneous Dirichlet conditions and initial conditions. In this paper we prove an L1-contraction principle and the uniqueness of entropy solutions under rather general assumptions on the data.

Modelling and experimental validation of thin layer indirect solar drying of mango slices
D. BATHIEBO
The thin layer solar drying of mango slices of 8 mm thick was simulated and experimented using a solar dryer designed and constructed in laboratory. Under meteorological conditions of harvest period of mangoes, the results showed that 3 “typical days” of drying were necessary to reach the range of preservation water contents. During these 3 da(...)

Effet du régime hydrique sur les rendements du gombo en culture de contre-saison
Rasmata NANA, Gérard ZOMBRE, Zoumbiessé TAMINI et Mahamadou SAWADOGO
L’étude à pour but de mettre en évidence la période de contre-saison favorable à la culture du gombo (Abelmoschus esculentus) et de déterminer la bonne fréquence d’arrosage. Pour cela, deux essais ont été réalisés sur trois écotypes 1 ; 19 et 22: le premier pendant la période froide (décembre-mars 2005) et le second durant la période chaude (a(...)

Existence and regularity of solutions for some partial functional integrodifferential equations in Banach spaces
Khalil Ezzinbi, Hamidou Toure, Issa Zabsonre
In this work, we study the existence and regularity of solutions for some partial functional integrodifferential equations in Banach spaces. We suppose that the undelayed part admits a resolvent operator in the sense given by Grimmer in [R. Grimmer, Resolvent operators for integral equations in a Banach space, Transaction of American Mathemati(...)

Discovering Africa's Newest Palm.
A. OUEDRAOGO
In 1996, a paper was published discussing the identity of a palm in the genus Borassus, occurring only in West Africa. It was identified as B. flabellifer, the Asian palmyrah palm, previously unknown in Africa. This paper recounts the story of an expedition to find and document these palms, resulting in the description of Borassus akeassii, Af(...)

Drying corn grains contained in a vertical channel with constant heat flux on walls
D. BATHIEBO
A previous report [] developed a numerical model to study the influence of thermal and mass Rayleigh numbers as well as Darcy and Lewis numbers on heat and mass transfer during the drying by natural convection of coffee grains which are treated as a porous medium. The code uses the Darcy-Brinkman momentum equation and the classical natural con(...)

Ex vivo Activities of β‐Lapachone and α‐Lapachone on Macrophages: A Quantitative Pharmacological Analysis Based on Amperometric Monitoring of Oxidative Bur...
I. TAPSOBA
Artificial synapses for femtomolar detection: Amperometry at platinized carbon fibre electrodes has been used to unravel the complexity of β‐lapachone's effects on cellular oxidative stress. α‐Lapachone, the pharmacologically inactive para‐quinone isomer, did not display such characteristics, but over longer incubation periods both quinones in(...)
