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(...)

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.(...)

Potential medicinal plants used by traditional healers in western areas of Burkina Faso.
ZERBO Patrice, COMPAORE Moussa, MEDA N.T.Roland, LAMIEN-MEDA Aline, KIENDREBEOGO Martin
Since prehistoric times, plants have been used as source of remedies for the treatment of diseases. People of each continent have their own practices about medicinal plants. Despite the large scale environmental degradation and recurrent drought, medicinal plants are still playing significant role in the management of various human diseases in(...)

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(...)

Characterization of briquettes coming from compaction of paper and cardboard waste at low and medium pressures
Ibrahim H. Gado, Salifou K. Ouiminga, Tizane Daho, Arsène H. Yonli, Moussa Sougoti, Jean Koulidiati
This study concerns the experimental characterization and compaction of paper/cardboard coming from waste of the city of Ouagadougou. The characterization results show that the category of waste of paper and cardboard encountered in Ouagadougou contains 39 % corrugated cardboard, 28 % of office paper, 18 % of non-corrugated cardboard, 7 % of n(...)

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(...)

Competition and facilitation-related factors impacts on crop performance in an agro-forestry parkland system in Burkina Faso
H. BAZIE
Parkia biglobosa and Vitellaria paradoxa are known to improve soil fertility and redistribute water under their crowns in parkland systems. A field experiment was conducted to separate above and belowground interactions between these species and associated Sorghum bicolor using root trenching and crown pruning during three cropping seasons. Tr(...)

Got issues? who cares about it? a large scale investigation of issue trackers from github
T. BISSYANDE
Feedback from software users constitutes a vital part in the evolution of software projects. By filing issue reports, users help identify and fix bugs, document software code, and enhance the software via feature requests. Many studies have explored issue reports, proposed approaches to enable the submission of higher-quality reports, and pres(...)

RELATING LOSS OF SOIL FERTILITY TO WATER AGGREGATE STABILITY AND NUTRIENT AVAILABILITY IN MOUNTAIN AGRICULTURAL CALCARIC SOILS
Patrizia Guidi, Gloria Falsone, Boussa Tockville Mare, Andrea Simoni, Paola Gioacchini, Gilmo Vianello
We investigated the topsoil from some mountain Regosols for their nutrient status and loss of fertility due to aggregate breakdown, establishing also the relationship between the nutrient losses, the soil characteristics and the aggregates stability. The aggregate stability varied from 57 to 80%. The nutrient losses differed among elements and(...)

Variation de caractères agromorphologiques et du Brix d’une collection de sorghos à tige sucrée du Burkina Faso
Baloua NEBIE, Romaric Kiswendsida NANEMA, Pauline BATIONO/KANDO, Ernest Renan TRAORE, Vanesse LABEYRIE, Nerbéwendé SAWADOGO, Mahamadou SAWADOGO, Jean-Didier ZONGO
Le sorgho à tige sucrée est de nos jours une plante d’intérêt utilisée pour la production de biocarburant. Au Burkina Faso, les ressources génétiques de ce sorgho ne sont pas connues, encore moins exploitées. Pour comprendre les relations entre la concentration en sucre des tiges et les caractères agromorphologiques de cette plante, 117 access(...)

hough plant metabolic changes are known to occur during interactions with bacteria, these were rarely challenged for pharmacologically active compounds suitable for further drug development. Here, the occurrence of specific chemicals with antiproliferative activity against human cancer cell lines was evidenced in hyperplasia (leafy galls) indu(...)
