Survival and growth responses of Jatropha curcas L. to three restoration techniques on degraded soils in Burkina Faso
S. TRAORE
Land degradation is a major problem in the Sahelian countries. Erosion control through establishment of vegetation cover is at important strategy to reverse the trend. Our research objective was to analyse the effects of three restoration techniques on Jatropha curcas L. seedlings growth and survivorship. We are conducted two separate field tr(...)

The flavanone naringenin reduces the production of quorum sensing-controlled virulence factors in Pseudomonas aeruginosa PAO1
M. KIENDREBEOGO
Preliminary screening of the Malagasy plant Combretum albiflorum for compounds attenuating the production of quorum sensing (QS)-controlled virulence factors in bacteria led to the identification of active fractions containing flavonoids. In the present study, several flavonoids belonging to the flavone, flavanone, flavonol and chalcone struct(...)

A comparative study of direct and indirect solar drying of mango
D. BATHIEBO
In this work, direct and indirect solar drying parameters of two mango varieties were estimated and compared using direct and indirect solar dryers under the same meteorological conditions. For both drying methods, drying curves were established and fitted using 10 semi-empirical models, drying rate and drying efficiency curves were determined(...)

Origines et développement de la métallurgie du fer au Burkina Faso et en Côte d’Ivoire. Premiers résultats sur le site sidérurgique de Korsimoro (Sanmatenga, Burkina Faso).
SIMPORE Lassina
En 2011-12, deux campagnes de recherche sur le terrain ont été organisées à Korsimoro (Burkina Faso), avec les universités de Ouagadougou et d'Abidjan. Par le passé, Korsimoro a été un centre de production du fer majeur à l'échelle de la région, comme en témoignent de très volumineux amas de scories, résidus issus de la réduction du

Comportement à la corrosion des alliages d’aluminium recyclés pour la confection de marmites
Brahima Sorgho1 , Samuel Paré2∗ , Boubié Guel3 , Lamine Zerbo1 , Karfa Traoré1 , Ingmar Persson
Des études sur la qualité des eaux souterraines et de surfaces au Burkina Faso ont révélé un niveau élevé de contamination de ces ressources par les métaux lourds, notamment dans le milieu urbain et aux alentours des mines. La présence de ces métaux est principalement due aux activités anthropiques liées à l’industrie, l’agriculture ou encore(...)

La végétation dans les ruines de Loropéni et leur zone tampon
SIMPORE Lassina
Sur la liste du patrimoine mondial, il existe deux principales catégories de sites. Les sites culturels et les sites naturels. Les ruines de Loropéni font partie de la catégorie culturelle, mais ont cette particularité d’être situées au milieu d’une zone de protection constituée d’une forêt claire et d’une savane arborée couvrant une superfici(...)

Antibacterial Potential and Antioxidant Activity of Polyphenols of Sesbania grandiflora
M.B.Ouattara, K.Konaté, M.Kiendrébéogo, N. Ouattara, M. Compaore, R. Meda, J.Millogo-Rasolodimby and O.G.Nacoulma
The antibacterial and antioxidant activity of Sesbanial grandiflora used in traditional pharmacopeia in Burkina Faso and elsewhere was evaluated. Aqueous, methanolic and hydro-acetone extractions were carried out on the leaves, stems, and granules, pods of fruit and roots of the plant. The phytochimic groups were identified by the tests of cha(...)

Woody species composition, diversity and structure of riparian forests of four watercourses types in Burkina Faso
A. THIOMBIANO
Riparian forests are classified as endangered ecosystems in general, particularly in sahelian countries like Burkina Faso because of human-induced alterations and civil engineering works. The modification of this important habitat is continuing, with little attention being paid to the ecological or human consequences of these changes. The obje(...)

Embolie pulmonaire simulant un infarctus aigu du myocarde antéroseptal: le piège diagnostique
N. YAMEOGO
Résumé L'embolie pulmonaire reste la grande simulatrice de la pathologie thoracique aiguë. Les données cliniques et les manifestations électrocardiographiques peuvent dévier le diagnostic vers un infarctus du myocarde. Nous rapportons un cas d'embolie pulmonaire bilatérale chez une patiente de 50 ans. L'électrocardiogramme montrait un sus-déca(...)

Uniqueness of traces on log-polyhomogeneous pseudodifferential operators
Catherine Ducourtioux, Marie Françoise Ouedraogo
We show how to derive the uniqueness of graded or ordinary traces on some algebras of log-
polyhomogeneous pseudodifferential operators from the uniqueness of their restriction to classical
pseudodifferential ones

Antimicrobial and antioxidant activities of essential oil and methanol extract of Matricaria chamomilla L. from Djibouti
125. Fatouma M. Abdoul-Latif, Nabil Mohamed, Prosper Edou, Adwa A. Ali, Samatar O. Djama, Louis-Clément Obame, Imael H. N. Bassolé5 and Mamoudou H. DICKO
The essential oil and methanol extracts of Matricaria Chamomilla L. were subjected to screening for their possible antioxidant activity by two complementary test systems, namely 2,2-diphenykpicrylhydrazyl (DPPH) free radical scavenging and β-carotene-linoleic acid assays. BHT was used as positive control in both test systems. In the DPPH test(...)

In order to evaluate the protective effect of Scoparia dulcis L.(Scrophulariaceae), a medicinal plant known to have medico-magic power, different extracts were prepared by successive extraction with hexane (HE), chloroform (CE) and methanol (ME) and by a soaking in acetone (80%). These extracts were checked for their protective role against ne(...)
