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
Amadé Ouédraogo, Anne Mette Lykke, Benjamin Lankoandé, Gabin Korbéogo
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(...)

Measurement of cholesterol sub-fractions, high density lipoprotein 2 and high density lipoprotein 3, in HIV infected patients treated with highly active antiretroviral therapy in Burkina Faso
Jean Sakandé, Josiane B. Kaboré, Elie Kabré, Boblwendé Sakandé, Mamadou Sawadogo
This paper described dyslipidemia caused by the metabolic effects of HIV and exposure to antiretroviral
therapy. The aim of this study was to appreciate the interest of the measurement of HDL sub-fractions
in the monitoring of human immunodeficiency virus (HIV) infected patients on antiretroviral treatment.
A case-control study was carried(...)

Entropy solution to nonlinear multivalued elliptic problem with variable exponents and measure data.
I. Nyanquini, S. Ouaro, S. Soma
We study a nonlinear elliptic problem governed by a general Leray-Lions operator with variable exponents and diffuse Radon measure data that does not charge the sets of zero p(⋅)-capacity. We prove a decomposition theorem for these measures (more precisely, as a sum of a function in L1(Ω) and of a measure in W−1,p′(⋅)(Ω)) and an existence 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(...)

The West African vegetation zones from the Sahara desert to the Guinean rainforests are shaped by a steep latitudinal precipitation gradient. Their taxonomical and functional composition changes considerably along this gradient. Based on comprehensive distribution data from herbariun collections and relevés this paper presents modelled distrib(...)

Insecticide resistance in Bemisia tabaci Gennadius (Homoptera: Aleyrodidae) and Anopheles gambiae Giles (Diptera: Culicidae) could compromise the sustainability of malaria vector control strategies in West Africa
Olivier Gnankiné , Imael H.N. Bassolé , Fabrice Chandre , Isabelle Glitho , Martin Akogbeto , Roch K. Dabiré , Thibaud Martin
Insecticides from the organophosphate (OP) and pyrethroid (PY) chemical families, have respectively, been in use for 50 and 30 years in West Africa, mainly against agricultural pests, but also against vectors of human disease. The selection pressure, with practically the same molecules year after year (mainly cotton), has caused insecticide re(...)
