Screening of Hepatitis G and Epstein-Barr Viruses Among Voluntary non Remunerated Blood Donors (VNRBD) in Burkina Faso, West Africa
Issoufou Tao, Cyrille Bisseye, Bolni Marius Nagalo, Mahamoudou Sanou, Alice Kiba, Guzin Surat, Tegwindé Rebeca Compaoré, Lassina Traoré, Jean Baptiste Nikiema, Virginio Pietra, Jean-Didier Zongo, Jacques Simpore
Abstract. In most sub-Saharan countries screening of blood-transmitted infections includes mainly HIV, HBV, HCV and syphilis. Many viruses such as Hepatitis G (HGV) and Epstein-Barr virus (EBV) which also carry a risk of transmission by blood transfusion raise the question of the extent of screening for these pathogens. This work aims to evalu(...)

Performances of neural networks and LDPC decoders for OFDM high speed transmission in optical fiber
Serge Roland Sanou, François Zougmoré, Marcel Kebré, Zacharie Koalaga, Ali Doumounia
This paper presents a comparison of the performances of coded OFDM (Orthogonal Frequency Division Multiplexing) for optical broadband transmission using Random Neural Network (RNN), a variant of RNN, Soft Decision Decoding (SDD) and LDPC channel decoding techniques. The performance evaluation is based firstly on the Error Vector Magnitude (EVM(...)

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(...)

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),(...)
