Phenolic compounds and antioxidant activities in some fruits and vegetables from Burkina Faso
121. BAYILI Romaric G., Fatoumata ABDOUL-LATIF, Oumou H. KONE, Mamounata DIAO, Imael H. N. BASSOLE, and Mamoudou H. DICKO
Levels of total phenolic compounds (TPC), proanthocyanidins (PAs) and antioxidant activities among sixteen fruits and vegetables commonly consumed in Burkina Faso were determined. Levels of TPC ranged from 0.21 to 3.33 mg of gallic acid equivalent per gram of fresh matter. The highest contents in TPC were found in hot chili pepper, okra, lemon(...)

3D STUDY OF BIFACIAL SILICON SOLAR CELL UNDER INTENSE LIGHT CONCENTRATION AND UNDER EXTERNAL CONSTANT MAGNETIC FIELD.
M. ZOUNGRANA, I. ZERBO, A. SERE, B. ZOUMA AND F. ZOUGMORE
This work presents a three-dimensional study of bifacial silicon solar cell under intense light concentration and under constant magnetic field. This approach is based on the resolution of the minority continuity equation, taking into account the distribution of the electric field in the bulk evaluated as a function of both majority and minori(...)

Influence d’une onde électromagnétique sur une photopile au silicium sous éclairement multi spectral en régime statique
I. Zerbo, M. Zoungrana, A.D. Seré, F. Ouedraogo, R. Sam, B. Zouma et F. Zougmoré
Dans ce travail, nous étudions l’influence d’une onde électromagnétique produite par une source de télécommunication (antenne émettrice) de puissance donnée sur le comportement d’une photopile en régime statique, éclairée par une lumière blanche et placée à une certaine distance de l’antenne. Après la résolution de l’équation de continuité des(...)

Nutraceutical Assessment of Four Amaranthus Species from Burkina Faso
Ouedraogo Ibrahim, Hilou Adama, Sombie Pierre Alexandre Eric Djifaby, Compaore Moussa, Millogo Jeanne and Nacoulma Odile Germaine
The use of the amaranths as vegetables is developed in Burkina Faso. Most known are Amaranthus dubius Mart. Ex. Thell, Amaranthus graecizans L., Amaranthus hybridus L. and Amaranthus viridis L. A. hybridus is most used and abundantly cultivated, however the others are more or less wild. Theaim of the present study was to investigate the nutrac(...)

Impact of land-use type and harvesting on population structure of a non-timber forest product-providing tree in a semi-arid savanna, West Africa
A. THIOMBIANO
Non-timber forest products (NTFPs) strongly contribute to livelihood security in the semi-arid tropics. Main factors determining the populations of NTFP-providing species are human activities. This study examined the impact of land-use, combined with rates and patterns of debarking and chopping on a NTFP-providing tree (Anogeissus leiocarpa) i(...)

Burden of rotavirus and other enteropathogens among children with diarrhea in Burkina Faso
K. SIMPORE
Objective There is limited information available regarding the etiology of gastrointestinal infections in Burkina Faso. The aim of this study was to investigate the prevalence and epidemiology of enteric pathogens causing gastroenteritis in young children, with a focus on rotavirus, and to investigate the levels of malnutrition and other clini(...)

Juvenile Paleoproterozoic crust evolution during the Eburnean orogeny ( 2.2–2.0 Ga), western Burkina Faso
Lenka Baratoux, Vaclav Metelka, Seta Naba, Mark W. Jessell, Michel Gregoire, Jerome Ganne
We have investigated three greenstone belts (Boromo, Houndé, and Banfora) and associated granitoid terrains, which form part of the Eburnean orogen, situated in western Burkina Faso. These belts expose tholeiitic basalts (basal unit) followed by calc-alkaline intermediate predominantly effusive volcanic and sedimentary suites geochemically rem(...)

A geophysically constrained litho-structural analysis of the Eburnean greenstone belts and associated granitoid domains, Burkina Faso, West Africa
Vaclav Metelka, Lenka Baratoux, Seta Naba, Mark W. Jessell
Interpretation of airborne geophysical data integrated with field structural and lithological observation was successfully employed in the creation of the litho-structural framework in a poorly exposed Paleoproterozoic granite-greenstone terrain of the West African Craton. The geophysical data portray with sufficient detail all of the litholog(...)

An organometallic derivative of a BAPTA ligand: towards electrochemically controlled cation release in biocompatible media
29. Koyel X. Bhattacharyya, Leıla Boubekeur-Lecaque, Issa Tapsoba, Emmanuel Maisonhaute, Bernd Schollhorn and, Christian Amatore
Calcium behaves as a chemical messenger in a wide variety of cells, and local variations in its
concentration play a key role in many biological processes. 1,2 The understanding of how calcium
affects cellular functions necessitates the precise modulation of calcium concentration with high
spatial and temporal resolution. Tremendou(...)
