The components of self-rated health among adults in Ouagadougou, Burkina Faso
Yentéma Onadja, Simona Bignami, Clémentine Rossier, Maria-Victoria Zunzunegui
Background
Although the relationship between self-rated health (SRH) and physical and mental health is well documented in developed countries, very few studies have analyzed this association in the developing world, particularly in Africa. In this study, we examine the associations of SRH with measures of physical and mental health (chronic d(...)

Optimization of copper indium gallium di-selenide (CIGS) based solar cells by back grading
S. Ouédraogo, R. Sam, F. Ouédraogo, M. B. Kebré, JM. Njaka, F Zougmoré
We performed modeling and simulation of Cu(In,Ga)Se2 (CIGS) thin film solar cell, using SCAPS-1D device simulator, and we especially investigated the influence of absorber back surface region grading. The band-gap in the back surface region, as well as the thickness of the back surface grading layer, were varied to achieve the optimal performa(...)

An empirical study of adoption of software testing in open source projects
T. BISSYANDE
Testing is an indispensable part of software development efforts. It helps to improve the quality of software systems by finding bugs and errors during development and deployment. Huge amount of resources are spent on testing efforts. However, to what extent are they used in practice? In this study, we investigate the adoption of testing in op(...)

Characterization, at Partial Loads, of the Combustion and Emissions of a Dual-Fuel Engine Burning Diesel and a Lean Gas Surrogate
Ali Diané , Gounkaou Woro Yomi , Sidiki Zongo , Tizane Daho , and Hervé Jeanmart
For decentralized power generation in West Africa, gas from a small biomass gasification unit can be used as the main fuel in a dual-fuel engine with diesel as the pilot fuel. To study the combustion in this type of engine (Lister Petter), experiments were conducted with a surrogate gas composed of liquefied petroleum gas and nitrogen (LPGN2),(...)

Influence of engine load and fuel droplet size on performance of a CI engine fueled with cottonseed oil and its blends with diesel fuel
Tizane Daho, Gilles Vaitilingom, Salifou K. Ouiminga, Bruno Piriou, Augustin S. Zongo, Samuel Ouoba, Jean Koulidiati
In this study, favorable conditions to achieve good combustion of cottonseed oil and its blends with diesel
fuel in a direct injection diesel engine have been highlighted. This has been performed by analyzing fuel
droplet size distribution and determining engine specific fuel consumption and thermal efficiency,
combustion parameters (igniti(...)

Popularity, interoperability, and impact of programming languages in 100,000 open source projects
T. BISSYANDE
Programming languages have been proposed even before the era of the modern computer. As years have gone, computer resources have increased and application domains have expanded, leading to the proliferation of hundreds of programming languages, each attempting to improve over others or to address new programming paradigms. These languages rang(...)

Host genetic factors affect susceptibility to norovirus infections in Burkina Faso
K. SIMPORE
Norovirus (NoV) constitutes the second most common viral pathogen causing pediatric diarrhea after rotavirus. In Africa, diarrhea is a major health problem in children, and yet few studies have been performed regarding NoV. The association of histo-blood group antigens (HBGA) and susceptibility to NoV infection is well established in Caucasian(...)

Potentials for promoting oil products identified from traditional knowledge of native trees in Burkina Faso
A. OUEDRAOGO
Oil products from native trees are far from fully exploited in West Africa. Only well-known species like shea (Vitellaria paradoxa CF Gaertn.) and oil palm (Elaeis guineensis Jacq.) receive attention. We used quantitative questionnaires in 12 villages in Western Burkina Faso to assess the knowledge of four ethnic groups on 28 tree species and(...)

Privatization of Education and Labor Force Inequality in Urban Francophone Africa: The Transition from School to Work in Ouagadougou
Calves Anne Emmanuel, Jean-François Kobiané and Afiwa N’Bouke
As in many other francophone African countries, there has been increased privatization of the school system in Burkina
Faso since the 1990s, especially in urban areas. Based on a unique retrospective survey conducted in Ouagadougou, this research investigates a largely unexplored issue in Africa: the impact of private schooling on subsequent(...)

Refractory bricks based on Tikaré (Burkina Faso) kaolinitic raw clay material
Mohamed Seynou, Pierre Flament, Moustapha Sawadogo, Jacques Tirlocq, Raguilnaba Ouedraogo
A raw clay material deposit in Burkina Faso has been used for refractory bricks production in the lab. The
extruded raw clay material has been fired at 1400°C to produce a chamotte grog that has been crushed into different
particle sizes. These have been mixed with 14%.wt of the raw clay material as a binder. The admixture has then been(...)

Algèbres de Lie triple sans idempotent
Joseph Bayara, Amidou Konkobo, Moussa Ouattara
Idempotents play an important role in the investigation of nonassociative algebras structure ([2],[18],,[21]). However, the existence of such elements is not always guaranteed, specially when dealing with algebras that are defined by polynomial identities. Hence, in many cases, one has to assume the existence of idempotents $([3,11,17])$ in or(...)
