Une approche reposant sur la datation des eaux souterraines et les investigations hydrochimiques a permis
d’évaluer l'origine, l'âge apparent et les mécanismes de recharge des eaux souterraines riches en CO2 qui
contribueraient à la recharge de gaz carbonique du lac Nyos. Un modèle de rejet de gaz en petites quantités
non toxiques à l’ex(...)

Le patrimoine méconnu des bois sacrés de la ville de Koudougou (Burkina Faso) : de la reconnaissance à la sauvegarde
YAMEOGO Lassane
Pour des raisons diverses, les sociétés rurales africaines ont organisé l’espace en privilégiant des lieux sacrés dotés d’interdits. Ces bois sacrés sont rattrapés par les dynamiques urbaines qui leur disputent l’espace. Le patrimoine que constituent ces jardins sacrés demeure inconnu du fait qu’il ne répond pas aux critères occidentaux du pat(...)

Détection biologique des résidus d’antibiotiques dans le lait et produits laitiers de vache consommés à Ouagadougou, Burkina Faso
Touwendsida Serge Bagré, Serge Samandoulougou, Mahamady Traoré, Daniel Illy, Gertrude Bsadjo- Tchamba, Hadiza Bawa-Ibrahim, S. Caroline Bouda, Alfred S. Traoré, Nicolas Barro
Objectif : L’élevage traditionnel au Burkina n’associe pas généralement les bonnes pratiques vétérinaires. Il se traduit par une utilisation anarchique des antibiotiques et le non-respect des délais d’attente. L’objectif est de mettre en évidence les résidus d’antibiotiques dans le lait et les produits laitiers consommés dans la ville de Ouaga(...)

Screening of antibiotics residues in beef consumed in Ouagadougou, Burkina Faso
Serge SAMANDOULOUGOU, André Jules ILBOUDO, Touwendsida Serge BAGRE, Fidèle W. TAPSOBA, Aly SAVADOGO, Marie-Louise SCIPPO and Alfred S. TRAORE
The anarchic use of antibiotics for therapeutic purposes or as a growth factor in Burkina Faso’s breeding is the origin of their residues present in consumed meat. These antibiotics residues have health, technological and microbiological consequences. The objective of this first study is to highlight the antibiotic residues in meat consumed in(...)

Theoretical Investigation of Base doping and illumination level effects on a bifacial silicon solar cell.
10.9734/BJAST/2015/1562810.9734/BJAST/2015/15628
In this paper, we are investigating theoretically the behavior of a bifacial silicon solar cell in steady state with different illumination conditions. The bifaciality coefficient and the conversion efficiencyare calculated for various rear side illumination conditions (traduced here by the illumination le(...)

Land cover change and plants diversity in the Sahel: A case study from northern Burkina Faso
B. NACOULMA
Understanding land cover degradation patterns and the effects of geomorphological units on phytodiversity is important for guiding management decisions and restoration strategies in the Sahelian vulnerables zones. This paper describes land cover degradation by combining Landsat TM image analysis and field data measurements in the Gourouol catc(...)

Microbiological Quality of Surface Water Treated with Moringa oleifera Seeds or Cakes during the Storage: Case Study of Water Reservoirs of Loumbila, Ziga and Ouaga 3 Dams in Burkina Faso
Kabore Aminata, Savadogo Boubacar, Otoidobiga C.Harmonie, Sawadogo Adama, Rosillon Francis, Traore S. Alfred, Dianou Dayéri
Water purification with Moringa oleifera seeds has received a lot of attention because it reduces water turbidity and pathogenic microorganisms. However, it is important to define the optimum conditions of storage to preserve the treated water quality. The study aims to investigate microbial quality of water treated with Moringa oleifera seeds(...)

Le syndrome des brides amniotiques et ses difficultés diagnostiques et de prise en charge au Burkina Faso
Kisito Nagalo, Roger Badiel, Fla Kouéta, François Housséini Tall, Diarra Yé
Résumé Le syndrome des brides amniotiques est une embryo-foetopathie rare, d'étiopathogénie encore inconnue, caractérisé par des malformations crânio-faciales, thoraco-abdominales, des membres et des extrémités. Afin de discuter des difficultés diagnostiques et thérapeutiques du syndrome des brides amniotiques, nous rapportons cinq cas de ce s(...)

Effect of land degradation on carbon and nitrogen pools in two soil types of a semi-arid landscape in West Africa
S. TRAORE
To determine the resilience of soil organic C and N pools during land degradation processes in a semi-arid landscape of West Africa, we compared the magnitude of soil organic C and N differences in bulk soil and aggregate fractions between contrasting types of land cover (degraded land and native land cover) and soil (Luvisols and Cambisols).(...)

Physicochemical and parasitological quality of vegetables irrigation water in Ouagadougou city, Burkina-Faso
Winkom Kpoda Noellie, Oueda Adama, Stephane Corentin Some Yelezouomin, Cisse Gueladio, Hama Maiga Amadou, Bouraima Kabre Gustave
The quality of irrigation water from different sources used by urban vegetable producers, the watered soils and vegetables in Ouagadougou was investigated. From December 2012 to December 2013, samples of water (97), lettuces heads (20), manure (10) and soil (9) were collected and analyzed for their parasitological quality using modified Bailen(...)

Fabrication of Amorphous Silver Nanowires by Helium Ion Beam Irradiation
Shehla, Ali A., Zongo S., Javed I, Ishaq A., Khizar H., Naseem S., Maaza M.
Amorphous silver nanowires (a-Ag NWs) are fabricated from crystalline Ag NWs by using 5 MeV helium (He+) ion beam irradiation. At low dose (5×1015 ion/cm2), few defects are created in Ag NWs. As dose increases, more damage to the crystalline structure of Ag NWs is observed. Finally at high dose (8×1016 ion/cm2), the face-centered cubic structu(...)

Fertility Decline and Child Schooling in Urban Settings of Burkina Faso
Bougma Moussa, Thomas K. LeGrand et Jean-François Kobiané
As evidenced in Western rich countries, Asia, and Latin America, lower fertility allows couples to invest more in each of their children's schooling. This postulate is the key rationale of family planning policies in sub-Saharan Africa. Yet, most studies on Africa have found no correlation or even a positive relationship between the number of(...)
