Effet des apports organiques et phosphates sur la nodulation, l’exportation de nutriments et les rendements du niébé associe au sorgho : cas de la région nord du Burkina Faso.
Daouda GUEBRE, Mohamed Traoré, Koulibi Fidèle Zongo et Edmond Hien
Les sols de la zone soudano-sahélienne sont généralement déficients en éléments nutritifs essentiels notamment en azote et en phosphore. Cela se traduit par une baisse progressive des rendements. Pour des raisons généralement alimentaire et économique, des associations céréales-légumineuses sont pratiquées dans la région Nord du Burkina Faso.(...)

Essential Oils as an Alternative to Pyrethroids’ Resistance against Anopheles Species Complex Giles (Diptera: Culicidae)
Olivier Gnankiné and Imaël Henri Nestor Bassolé
Widespread resistance of Anopheles sp. populations to pyrethroid insecticides has led to the search for sustainable alternatives in the plant kingdom. Among many botanicals, there is great interest in essential oils and their constituents. Many researchers have explored essential oils (EOs) to determine their toxicity and identify repellent m(...)

Cattle farming can promote diarrheal disease transmission through waste, effluents or cattle fecal matter. The study aims to characterize the diarrheagenic Escherichia coli (DEC) isolated from cattle feces, manure in the composting process and slurry, collected from four cattle markets in Ouagadougou. A total of 585 samples (340 cattle feces,(...)

Antioxidant Screening and Polyphenols profiling of Ipomoea asarifolia (Desr.) Roem. & Schult (Convolvulaceae)
MEDA Nâg-Tiero Roland, COMPAORE Moussa, BANGOU Mindiédiba Jean, VLASE Laurian, KIENDREBEOGO Martin, OUEDRAOGO Anicet Georges
Ipomoea asarifolia est largement utilisé en Afrique dans le traitement de diverses maladies. Au Burkina Faso, cette plante est bien utilisée en médecine traditionnelle pour traiter le paludisme, les convulsions et les rhumatismes. Pour cela, les fractions organiques de l'extrait hydroacétonique de I. asarifolia ont été sélectionnées pour leur(...)

Spatially explicit multi-threat assessment of food tree species in Burkina Faso: A fine-scale approach
B. NACOULMA
Over the last decades agroforestry parklands in Burkina Faso have come under increasing demographic as well as climatic pressures, which are threatening indigenous tree species that contribute substantially to income generation and nutrition in rural households. Analyzing the threats as well as the species vulnerability to them is fundamental(...)

3-D modeling of grains sizes effects on polycrystalline silicon solar cell under intense light illumination
Mahamadi SAVADOGO, Martial ZOUNGRANA, Issa ZERBO, Boubacar SORO, Dieudonné Joseph BATHIEBO
This work presents a 3D modelling study of the effect of grain size on the electrical parameters such as maximum electric power, fill factor and conversion efficiency, of a polycrystalline silicon solar cell.
To study effects of grains size on the performance of the polycrystalline silicon solar, we used in our model variables silicon grain s(...)

A theoretical study of radio wave attenuation through a polycrystalline silicon solar cell
Adama OUEDRAOGO, Vinci de Dieu Bokoyo BARANDJA1, Issa ZERBO, Martial ZOUNGRANA, Emmanuel Wendsongré RAMDE, Dieudonné Joseph BATHIEBO
One-dimensional study of both electronic and electrical parameters of a silicon solar cell in the presence or not of an electric eld, a magnetic eld, or an electromagnetic eld does not take into account the grain size and the grain boundary recombination velocity. A three-dimensional study, on the contrary, takes those factors into account.(...)

The emergence and persistence of multidrug-resistant (MDR) diarrheagenic Escherichia coli (DEC) causing acute diarrhea is a major public health challenge in developing countries. The aim of this study was to evaluate the resistance phenotypes of DEC isolated from stool samples collected from children less than 5 years of age with acute diarrhe(...)

Abstract. Epstein Barr Virus (EBV) and Human Herpes Virus 6 (HHV-6) are responsible for severe diseases, particularly in immunocompromised persons. There is limited data of the infection of these opportunistic viruses in Burkina Faso. The purpose of this study was to characterize EBV and HHV-6 subtypes and to assess their impact on CD4 T cell(...)

Enhanced extraction of flavonoids from Odontonema strictum leaves with antioxidant activity using supercritical carbon dioxide fluid combined with ethanol
OUEDRAOGO Jean Claude W., DICKO Cedric, KINI Félix B., BONZI-COULIBALY Yvonne L., DEY Estera Szwajcer
Flavonoids were extracted from Odontonema strictum leaves by supercritical carbon dioxide, with ethanol. The effect of three independents variables (time, pressure and temperature) on the Total Flavonoid Content (TFC) were optimized by factorial investigation. The TFC and flavonoid recovery varies respectively from 99.33 to 247.78 mg/g of drie(...)
