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(...)

Modélisation de la combustion d’un mélange de matériaux cellulosique et plastique dansu n 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
Le présent travail concerne l’étude de l’influence des débits d’air comburant sur les rendements des émissions de gaz, lors de la combustion de mélange de tiges de mil et de sacs plastiques en polyéthylène, dans un prototype de four de potier. Au cours de ces investigations, nous nous sommes intéressés au taux d’oxygène résiduel (O2) et aux ém(...)

Le comportement thermiquede céramiques élaborées à partir d’argiles locales du Burkina Faso a été caractérisé dans cette étude. L’argile SIT est composée majoritairement de montmorillonite,de quartz, d’albite de kaolinite et d’illite, tandis que l’argile GAR contient les phases majeures que sont le talc, la dolomite et la chlorite. Des mélange(...)

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(...)

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(...)

Elliptic problem involving diffuse measure data
Noureddine Igbida, Stanislas Ouaro and Safimba Soma
In this paper, we study a suitable notion of solution for which a nonlinear elliptic problem governed by a general Leray–Lions operator is well posed for any diffuse measure data. In terms of the paper (Brezis et al., 2007, [10]), we study the notion of solution for which any diffuse measure is “good measure”.

Mercury, arsenic and selenium concentrations in water and fish from sub-Saharan semi-arid freshwater reservoirs (Burkina Faso)
Ousséni Ouédraogo, Marc Amyot
Despite intensive mining activities in Burkina Faso, little is known on the environmental impacts of metals and
metalloids potentially released from these activities. Water samples and 334 fish from 10 reservoirs were
taken in order to evaluate the extent of mercury (Hg), selenium (Se) and arsenic (As) contamination in aquatic
systems and t(...)

To what extent do protected areas determine the conservation of native flora? A case study in the Sudanian zone of Burkina Faso
A. OUEDRAOGO
Natural vegetation contributes significantly to the daily needs of local people especially in the developing countries. This exerts a high pressure on freely accessible natural savannas and jeopardizes the conservation of protected areas. In Burkina Faso, conservation measures, such as the creation of protected forests, have been taken to safe(...)

Comparison of phenolic compounds and antioxidant capacities of traditional sorghum beers with other alcoholic beverages
ABDOUL-LATIF Fatouma, Romaric G. BAYILI, Louis C. OBAME, Imael H.N. BASSOLE, and Mamoudou H. DICKO
Thirty samples of sorghum beers “dolo” were selected from traditionally fermented household manufacturers from Burkina Faso. Dolo samples were screened for their total phenolic content, proanthocyanidins and putative antioxidant capacities, and were compared with industrial beers and wines. Total phenols were measured using the Folin-Ciocalteu(...)

L'introuvable articulation transport-urbanisme ou la face cachée de la décentralisation à Ouagadougou
KIETTYETTA Jean Yves
La gestion urbaine en vigueur à Ouagadougou est exercée sur fond de décentralisation. Le Code général des collectivités locales établit une répartition des compétences entre l'Etat et les collectivités locales et préconise que cette répartition soit régie par les principes de subsidiarité, de progressivité et de proximité. Onze prérogatives le(...)
