« Les héros et la mort dans les épopées de Soundjata et de Gilgamesh »
Alain Joseph Sissao
L’épopée de Soundjata constitue un récit phare sur la constitution du Mandé. Après la mort
du buffle totem de la mère du héros, qui permet de réaliser l’oracle de la naissance de
Soundjata, nous assistons à d’autres décès de proches dans la trajectoire de la maturité du
héros. Ainsi on peut noter la mort du frère qui le chassa du trône et q(...)

Actions of the Burkina Faso Women in Physics Working Group at the University of Ouagadougou
Pétronille Kafando and Issa Zerbo
At the University of Ouagadougou, the largest university in Burkina Faso, the percentage of female student
enrollment in the Exact and Applied Sciences Unit was 5.1% (for all the levels) from 2006 to 2009—this rate was
2.3% for physics. For the same period, 22 women out of 455 students (4.8%) were enrolled in PhD (all the fields of
the Exac(...)

Periodicity in the α-norm for some partial functional differential equations with infinite delay.
K. Ezzinbi, B.A. Kyelem, S. Ouaro
Using some fixed point theorems, the authors investigate the existence of periodic solutions in the α-norm for the partial functional differential equation with infinite delay
dudt(t)=−Au(t)+f(t,ut),t∈ℝ.
Here f:ℝ×α→X is a continuous function, σ-periodic in its first argument, X is a Banach space, α is the phase space, A:D(A)⊆X→X is a close(...)

Modeling the emission of hydrogen chloride and free chlorine from the thermal treatment of polyvinyl chloride- (PVC-) based plastic materials
J.P.B. Karama,∗, A. Béré, J. Lemonon, T. Daho, A. Dissa, Y. Rogaume, J. Koulidiati
To simulate the emission of hydrogen chloride gas and free chlorine from the thermal treatment of plastic materials, especially those based on PVC, two mathematical models have been developed. An experimental research program has been undertaken to validate these models. It is found that the masses of hydrogen chloride and free chlorine comput(...)

Haemoglobin S and C affect the motion of Maurer's clefts in Plasmodium falciparum-infected erythrocytes
Nicole Kilian, Martin Dittmer, Marek Cyrklaff, Djeneba Ouermi, Cyrille Bisseye, Jacques Simporé, Friedrich Frischknecht, Cecilia P. Sanchez, Michael Lanzer
The haemoglobinopathies S and C protect carriers from severe Plasmodium falciparum malaria. We have recently shown that haemoglobin S and C interfere with host-actin remodelling in parasitized erythrocytes and the generation of an actin network that seems to be required for vesicular protein trafficking from the Maurer's clefts (a parasite-der(...)

Entropy solutions for nonlinear elliptic anisotropic homogeneous Neumann problem
B.K. Bonzi, S. Ouaro, F.D.Y. Zongo
We prove the existence and uniqueness of an entropy solution for nonlinear anisotropic elliptic equations with Neumann homogeneous boundary value condition for L1-data. We prove first, by using minimization techniques, the existence and uniqueness of a weak solution when the data is bounded, and by approximation methods, we prove a result of e(...)

Caractérisation du fonctionnement des aquifères dans la région de Ouagadougou à partir d'une étude de la qualité chimique des eaux
Suzanne Ouandaogo-Yaméogo, Bernard Blavoux, Julien Nikiema, Alain Nindaoua Savadogo
Une partie de l’alimentation en eau potable de Ouagadougou provient d’environ 1 800 puits traditionnels et 100 forages plus profonds de 40 à 65 m en moyenne. Une étude hydrochimique a été menée pour mieux connaître la qualité de la ressource en eau captée. Ses résultats permettent de proposer un modèle conceptuel du fonctionnement des aquifè(...)

Inhibition of Bacillus cereus growth by bacteriocin producing Bacillus subtilis isolated from fermented baobab seeds (maari) is substrate dependent
112. Donatien, KABORÉ Dennis Sandris Nielsen, Hagrétou Sawadogo-Lingani, Bréhima Diawara, Mamoudou H. DICKO, Mogens Jakobsen, Line Thorsen
Maari is a spontaneously alkaline fermented food condiment made from baobab tree seeds. Due to the spontaneous nature of maari fermentations growth of the opportunistic human pathogen Bacillus cereus is occasionally observed. Bacillus subtilis strains are important for alkaline seed fermentations because of their enzymatic activities contribut(...)

Effect of Long-Term use of Sida rhombifolia L. Extract on Haemato-Biochemical Parameters of Experimental Animals.
Ouédraogo M., Zerbo P., Konaté K., Barro N. and Sawadogo L.L
Sida rhombifolia L. is used as a remedy for inflammatory disorde and some other diseases in African folk medicine. The present study was conducted to evaluate the haematological and biochemical parameters and toxic effects of aqueous acetone extracts of Sida rhombifolia L. in mice Swiss and albinos Wistar rats. Sida rhombifolia L. is used as a(...)

Numerical Study of the Routes toward Chaos of Natural Convection within an Inclined Enclosure
D. BATHIEBO
Two-dimensional numerical study of transient natural convection in an inclined cubic cavity filled with air using stream function-vorticity form for the Navier-Stokes equations has been carried out to explore the route toward chaos. The hot and cold vertical walls are maintained isothermal at temperature T c and T h respectively and the other(...)

Ampleur des populations « rapatriées » dans le Sud-Ouest du Burkina Faso à la suite du conflit en Côte d’Ivoire et conséquences sur la scolarisation
Kobiané Jean-François
La crise socio-politique et militaire qu’a connue la Côte d’Ivoire au cours des décennies 90 et 2000, a eu de nombreuses conséquences tant du point de vue économique, social que démographique sur les pays limitrophes. Du fait des liens historiques qui les lient mais aussi de l’ampleur des mouvements historiques de migration (notamment l’émigra(...)

N. Thiam, A. Diao, M. Wade, M. Ndiaye, I. Zerbo, M. Sarr, A. S. Maïga and G. Sissoko
In this study, we present the study of the photo-thermal response of a monofacial silicon solar cell illuminated
by a multispectral light for a constant modulated frequency. Solving the continuity equation for minority carriers in the
base of the solar cell resulting in the terms of the heat equations in the presence of an optical source. Th(...)
