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(...)

Three-dimensional study of a polycrystalline silicon solar cell: the influence of the applied magnetic field on the electrical parameters
A Dieng, I Zerbo, M Wade, A S Maiga and G Sissoko
In this paper, we present a theoretical 3D study of a polycrystalline silicon solar cell in frequency modulation under polychromatic illumination and applied magnetic field. The influence of the applied magnetic field on the diode current density, Jd , and both electric power–photovoltage and photocurrent–photovoltage characteristics are discu(...)

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(...)

Abstract Sickle-cell disease (SCD) patients are at high risk of developing malaria which is a major contributor to morbidity andmortality in this disease. In Senegal, malaria transmission is high during rainy season, between July and October, and it was noted that sickle-cell crisis are frequent during this period. Then we carried out a double(...)

Antioxidant potential of 4-acyl isochroman-1, 3-diones
Djandé Abdoulaye, Kiendrébéogo Martin, Compaoré Moussa, Kaboré Léopold, Nacoulma G. Odile, Aycard Jean-Pierre and Saba Adama
A new family of compounds (4-acyl isochroman-1,3-diones), demonstrating antioxidant properties, have been
synthesized and described. Their antioxidant properties are studied herein. These antioxidant characters increased with
the electronic withdrawing character of the acyl substituent. So, 4-p-Cyanobenzoyl isochroman-1,3-dione and 4-pNitrob(...)

Antibacterial potential and antioxidant activity of polyphenols of Sesbania grandiflora
M. KIENDREBEOGO
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(...)
