Phytochemical Analysis and in vitro Antifungal Profile of Bioactive Fractions from Sterculia setigera Del. (Sterculiaceae)
Ouédraogo M., Konaté K., Zerbo P., Barro N, awadogo L.L.
Sterculia setigera L. is a small evergreen tree having antimicrobial, anti-inflammatory effects. Leaves of Sterculia setigera have been investigated for its phytochemical and antifungal properties. In the present study, aqueous acetone extract and fractions of leaf from Sterculia setigera were used. Quantitative analysis of extract and fractio(...)

In vitro antifungal activity of flavonoid diglycosides of Menthapiperita and their oximes derivatives against two cereals fungi
Ousmane Ilboudo, Schémaeza Bonzi, Issa Tapsoba, Irénée Somda, Yvonne L. Bonzi-Coulibaly
Flavonoids due to their various interesting biological properties such as antifungal activity were investigated in Mentha piperita leaves. The butanolic fraction obtained from the hydro-alcoholic crude extract of M. piperita is rich in flavonoids; it reduced in vitro the mycelium growth of Phoma sorghina and Fusarium moniliforme around 72% and(...)

Soil crusting impact on soil organic carbon losses by water erosion
S. Maïga-Yaleu, I. Guiguemde, H. Yacouba, H. Karambiri, O. Ribolzi, A. Bary, R. Ouedraogo, V. Chaplot
The Sahelian region, characterized by erratic, heavy rainfalls and low soil organic carbon (SOC) stocks, is highly vulnerable to land degradation. While water erosion is recognized as being a main mechanism of SOC losses, little research has yet been done to investigate the role which soil surface crusting might have on SOC losses. The main ob(...)

Network structure of social coding in GitHub
T. BISSYANDE
Social coding enables a different experience of software development as the activities and interests of one developer are easily advertised to other developers. Developers can thus track the activities relevant to various projects in one umbrella site. Such a major change in collaborative software development makes an investigation of networki(...)

Empirical evaluation of bug linking
T. BISSYANDE
To collect software bugs found by users, development teams often set up bug trackers using systems such as Bugzilla. Developers would then fix some of the bugs and commit corresponding code changes into version control systems such as svn or git. Unfortunately, the links between bug reports and code changes are missing for many software projec(...)

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(...)

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(...)

Study of the Photothermal Response of a Monofacial Solar Cell in Dynamic Regime Under a Multispectral Illumination
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(...)

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(...)

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(...)

Investigation of building energy autonomy in the sahelian environment
O Coulibaly , A Ouedraogo , F Kuznik , D Baillis and J Koulidiati
In this study, the energy generation of a set of photovoltaic panels is compared with the energy load of a building in order to analyse its autonomy in the sahelian environment when taking into account, the orientation, the insulation and the energy transfer optimisation of its windows. The Type 56 TRNSYS multizone building mode(...)
