Rotavirus in diarrheal children in rural Burkina Faso: high prevalence of genotype G6P[6]
Johan Nordgren, Isidore Juste O Bonkoungou, Leon W Nitiema, Sumit Sharma, Djeneba Ouermi, Jacques Simpore, Nicolas Barro, Lennart Svensson
Group A rotavirus (RVA) is the most common cause of severe gastroenteritis in young children globally, and responsible for a significant number of deaths in African countries. While vaccines are available, trials have shown a lesser efficacy in Africa. One of the reasons could be the prevalence and/or emergence of unusual or novel RVA strains,(...)

Modélisation de la combustion d’un mélange de matériaux cellulosique et plastique dans un four de potier : Influence des débits d’air primaires et secondaires sur les émissions de NO, CO2 et O2
Salifou K. Ouiminga, Thomas Rogaume, Tizane Daho, Samuel Ouoba, Jean Koulidiati.
This work concerns the study of the influence of air flow on yields of gas emissions during the combustion of a mixture of millet stalks and polyethylene bags in a prototype of kiln. During these investigations, we looked at the rate of residual oxygen (O2) and emissions of carbon dioxide (CO2) and nitrogen monoxide (NO) as a function of prima(...)

A SVM-based incremental anti-pattern detection approach.
Abdou Maiga, Nasir Ali, Neelesh Bhattacharya, Aminata Saban_e, Yann-Gael Gueheneuc, Giuliano Antoniol, Esma Ameur. SMURF
In current, typical software development projects, hundreds of developers work asynchronously in space and time and may introduce anti-patterns in their software systems because of time pressure, lack of understanding, communication, and-or skills. Anti-patterns impede development and maintenance activities by making the source code more diffi(...)

The influence of termite-induced heterogeneity on savanna vegetation along a climatic gradient in West Africa
Arne Erpenbach, Markus Bernhardt-Römermann, Rüdiger Wittig, Adjima Thiombiano and Karen Hahn
Termites are renowned ecosystem engineers. Their mounds have been described as an important element of savanna vegetation dynamics, but little is known about their large-scale impact on vegetation composition. To investigate the influence of termite-induced heterogeneity in savannas along a climatic gradient in West Africa termite mound vegeta(...)

Acacia communities and species responses to soil and climate gradients in the Sudano-Sahelian zone of West Africa
S. TRAORE
Abiotic environmental factors have a major impact on the distribution and performance of plant species. In order to assess two major species–environmental relations in Sudano-Sahelian Acacia woodlands, we tested the relationship of soil and climate variables on plant diversity as well as on species responses. The indicator species values clust(...)

Evidence for population-specific positive selection on immune genes of Anopheles gambiae
A. GNEME
Host-pathogen interactions can be powerful drivers of adaptive evolution, shaping the patterns of molecular variation at the genes involved. In this study, we sequenced alleles from 28 immune-related loci in wild samples of multiple genetic subpopulations of the African malaria mosquito Anopheles gambiae, obtaining unprecedented sample sizes a(...)

Experimental hut evaluation of Fendona 6SC®-treated bednets and Interceptor® long-lasting nets against Anopheles gambiae sl in Burkina Faso
A. BADOLO
Background & objectives: Malaria prevention relies heavily on insecticide-treated bednets. Even though the benefits of bednets have been proven that in most of the studies carried out in Africa, their efficacy remains dependent on local conditions. In this study, under field conditions, we evaluated the efficacy of two LLINs (PermaNet® vs Inte(...)
