Impact des gradients topographique et anthropique sur la diversité des formations ligneuses soudaniennes
Loyapin BONDÉ, Oumarou OUÉDRAOGO, François KAGAMBÈGA, Joseph I. BOUSSIM.
Le paysage soudanien est en pleine mutation avec une conversion progressive des formations soudaniennes en formations sahéliennes. Dans cette étude, menée sur les formations ligneuses soudaniennes, l’objectif était d’évaluer, d’une part, les effets isolés du mode d’utilisation des terres et de la position topographique et, d’autre part, celui(...)

RELATIONSHIPS BETWEEN SOIL MICROBIAL BIOMASS, AGGREGATE STABILITY AND AGGREGATE ASSOCIATED-C: A MECHANISTIC APPROACH
Patrizia Guidi, Gloria Falsone, Mare Boussa Tockville, Gilmo Vianello
For the identification of C pools involved in soil aggregation, a physically-based aggregate fractionation was proposed, and additional pretreatments were used in the measurement of the 1-2 mm aggregate stability in order to elucidate the relevance of the role of soil microorganisms with respect to the different aggregate breakdown mechanisms.(...)

Jeu et enjeux mystiques dans le champ du transport
OUATTARA Siaka
Le transport routier semble simplement soumis à la détention d'un permis de conduire et d'un véhicule respectant les normes sécuritaires nationales. Mais par-delà cette impression, des pratiques diverses et multiples s'y retrouvent. En effet, au Sénégal, tout comme dans bon nombre de pays africains, le domaine du transport et celui des croyanc(...)

Etude de l’adsorption d’ions fluorures par une bentonite du Niger
Marou Gourouza , Ibrahim Natatou, Karifa Bayo , Anne Boos
Résumé : Nous avons étudié la capacité de défluoruration d’une argile de Sabon-karré de la région de Tahoua en
République du Niger. L’argile brute n’adsorbe pas les fluorures, il en libère au contraire. La calcination de cette argile, à
700°C pendant 6 h, a permis la génération de sites d’adsorption de fluorures. Le pourcentage de fluorures(...)

Pseudo Almost Periodic Solutions of class r for Some Neutral Partial Functional Differential Equations
Khalil Ezzinbi, Hamidou Toure, Issa Zabsonre
The aim of this work is to investigate the existence and uniqueness of pseudo almost periodic solutions of class r for some neutral partial functional differential equations in a Banach space when the delay is distributed using the variation of constants formula and the spectral decomposition of the phase space developed in Adimy et al. (Can A(...)

Pression anthropique et stratégies de préservation des ressources naturelles au Burkina Faso : cas de ressources forestières à Farako-Bâ
DIPAMA Jean-Marie
Dans la province du Houet se trouve le bassin versant de Farako-Bâ qui couvre une superficie de 428 km² et regorge d'importantes ressources forestières. Mais depuis quelques décennies, ces ressources sont soumises à une forte dégradation. Pour les populations riveraines la dégradation résulterait des péjorations climatiques. A cela s'ajoutent(...)

Combustion of vegetable oils under optimized conditions of atomization and granulometry in a modified fuel oil burner
Tizane Daho, Gilles Vaitilingom, Oumar Sanogo, Salifou K. Ouiminga, Augustin S. Zongo, Bruno Piriou, Jean Koulidiati
The use of vegetable oils in burners represents an attractive alternative to the use of heating fuel oil (HFO) in heat production for domestic heating, small industrial units, drying of various products etc. In this work, a characterization of the combustion of cottonseed oil in a modified burner (type Riello 40N10) was performed to assess its(...)

Stability analysis of a schistosomiasis model with delays
Aboudramane Guiro, Stanislas Ouaro, Ali Traoré
In this work, a nonlinear deterministic model for schistosomiasis transmission including delays with two general incidence functions is considered. A rigorous mathematical analysis is done. We show that the stability of the disease-free equilibrium and the existence of an endemic equilibrium for the model are stated in terms of key threshold p(...)
