La performance comparée des compagnies de distribution d’eau en Afrique de l’ouest par la méthode DEA : cas de 3 compagnies à mode de gestion différente
BATIONO Robert
La situation que présente l’Afrique en matière d’accès à l’eau potable reste toujours critique. Les compagnies de distribution d’eau n’arrivent pas à atteindre les standards internationaux en offrant de l’eau à toute la population. Cette insuffisance met en évidence la performance technique de ces compagnies d’eau. Pour l’ensemble des compagni(...)

CHESS: an innovative concept for a new generation of population surveillance
B. SOURA
Google Scholar See all References However, one of the major difficulties in assessment of the Millennium Development Goals (MDGs) has been the absence of effective measurability. Data of better quality and greater quantity, especially at the subnational level, must underpin the SDGs.We propose a new generation of population surveillance operat(...)

Pour un ancrage sociologique de l’alphabétisation au Burkina Faso. Analyse des besoins langagiers des populations burkinabè
MAÏGA Alkassoum, NAPON Abou et SORE Zakaria
Au Burkina Faso, une trentaine de langues nationales sont utilisées officiellement pour l’alphabétisation des adultes. En dépit des efforts fournis, la situation de l’alphabétisation ne s’améliore guère et pose la question du choix des langues utilisées pour enseigner. L’article rend compte d’une étude qui a visé à cerner les besoins langagier(...)

Détermination d’années météorologiques types utilisées pour la simulation thermique et énergétique des bâtiments de dix villes du Burkina Faso
Ousmane COULIBALY, Emmanuel OUEDRAOGO, Abdoulaye OUEDRAOGO et Jean KOULIDIATI.
Les problématiques énergétiques actuelles conduisent à améliorer la conception des bâtiments ainsi qu’à accroître l’utilisation des systèmes utilisant les énergies renouvelables (ENR). La mise en place de ces objectifs passe par l’évaluation des performances thermiques et énergétiques grâce à des codes de simulation détaillés tel que TRNSYS. D(...)

External magnetic field effect on bifacial silicon solar cell's electric power and conversion efficiency
Issa ZERBO, Martial ZOUNGRANA, Idrissa SOURABIE, Adama OUEDRAOGO, Bernard ZOUMA, Dieudonné Joseph BATHIEBO
Abstract:This article presents a modelling study of external magnetic eld effect on a bifacial silicon solar cell's electric power and conversion efficiency.
After the resolution of the magnetotransport equation and continuity equation of excess minority carriers, we
calculate the photocurrent density and the photovoltage and then we deduce(...)

Reticulate Speciation and Barriers to Introgression in the Anopheles gambiae Species Complex
A. GNEME
Speciation as a process remains a central focus of evolutionary biology, but our understanding of the genomic architecture and prevalence of speciation in the face of gene flow remains incomplete. The Anopheles gambiae species complex of malaria mosquitoes is a radiation of ecologically diverse taxa. This complex is well-suited for testing for(...)

Energy-free Security in Wireless Sensor Networks
Adel Elgaber (1) , Julien Bernard (1) , Yacouba Ouattara (1)
Wireless sensor networks are often deployed in open and uncontrolled environments that make them more vulnerable to security attacks. Cryptographic algorithms can be used to protect the data collected by the sensors against an intruder. The cost in terms of energy to provide enough security can be quite large as these algorithms may be very co(...)

Kola nuts were regularly chewed by West Africans and Beninese in particularly. The aim of this
study was to investigate nutritional and anti-nutrient content of three Benin’s kola nuts (Cola nitida,
Cola acuminata and Garcinia kola). Proximate composition of the three species of kola nuts
was assessed using standard analytical AOAC methods.(...)

Modelling Study of Magnetic Field’s Effects on Solar Cell’s Transient Decay
Senghane Mbodji, Martial Zoungrana, Issa Zerbo, Biram Dieng, Gregoire Sissoko
Experimental setup of transient decay which occurs between two steady state operating points is recalled. The continuity equation is resolved using both the junction dynamic velocity (Sf) and back side recombination velocity (Sb). The transient excess minority carriers density appears as the sum of infinite terms. Influence of magnetic field o(...)

A 3D Modelling of Solar Cell’s Electric Power under Real Operating Point
Mayoro Dieye, Senghane Mbodji, Martial Zoungrana, Issa Zerbo, Biram Dieng, Gregoire Sissoko
This work, based on the junction recombination velocity (Sfu) concept, is used to study the solar cell’s electric power at any real operating point. Using Sfu and the back side recombination velocity (Sbu) in a 3D modelling study, the continuity equation is resolved. We determined the photocurrent density, the photovoltage and the solar cell’s(...)

M. KIENDREBEOGO
The leaves of three Mentha species harvested in Algeria, Mentha spicata L.(MS), Mentha pulegium L.(MP) and Mentha rotundifolia (L.) Huds (MR) were examined for their content in polyphenols and for some activities-linked biological properties these could impart. The contents in total phenolics (TPC) and flavonoids (TFC) were evaluated by the Fo(...)
