Pseudo Almost Periodic Solutions of infinite class for Neutral Partial Functional Differential Equations with infinite delay
Khalil Ezzinbi and Issa Zabsonre
The aim of this work is to investigate the existence and uniqueness of pseudo almost periodic solutions for some neutral partial functional differential equations in a Banach space when the delay is distributed using the variation of constants formula and the spectral decomposition of the phase space developed in Adimy et al. [M. Adimy, K. Ezz(...)

Diversité et structure des cordons ripicoles le long de la sirba (Nord-Est du Burkina Faso)
Elice KABORE *, Oumarou SAMBARE, Amadé OUEDRAOGO et Adjima THIOMBIANO
es Cordons ripicoles sont des végétations bordant les rivières à écoulement temporaire et qui possèdent des sols riches et une grande capacité en bois. Ces ressources sont anarchiquement utilisées par l’homme créant ainsi la fragmentation des berges. Cette étude s’inscrit dans le cadre d’une évaluation de la diversité et de la structure des co(...)

Population structure of the widespread species, Anogeissus leiocarpa (DC.) Guill. & Perr. across the climatic gradient in West Africa semi-arid area
A. OUEDRAOGO
In the climate change context, widely distributed plant species can serve as relevant barometers of ecosystems' sensitivity or resilience to disturbances. This study aimed at assessing the population structure and individual morphological traits of Anogeissus leiocarpa, a widespread tree species, across a broad strip of land, from the north to(...)

« Essai méthodologique et étude de cas sur le patrimoine industriel au Burkina Faso »
COULIBALY Pon Jean-Baptiste
Ce texte est le fruit d’une communication sur les concepts de patrimoine et d’archéologie industriel au Burkina Faso. Notre propos visait à prouver que les notions d’archéologie industrielle et de patrimoine industriel peuvent bien s’appliquer à notre contexte même si les deux concepts ne sont pas véritablement intégrés en Afrique. Ce travail(...)

Periodic solutions in the α-norm for some neutral partial functional differential equations with finite delay
K. Ezzinbi, B.A. Kyelem, S. Ouaro
The aim of this work is to study the existence of periodic solutions in the α-norm for some partial differential equations of neutral type with finite delay. We assume that the linear part is densely defined and is the generator of an analytic semigroup. The delayed part is assumed to be periodic with respect to the first argument. In the nonh(...)

Prevalence of HPV high-risk genotypes in three cohorts of women in Ouagadougou (Burkina Faso)
Theodora M Zohoncon, Cyrille Bisseye, Florencia W Djigma, Albert T Yonli, Tegwinde R Compaore, Tani Sagna, Djeneba Ouermi, Charlemagne MR Ouédraogo, Virginio Pietra, Jean-Baptiste Nikiéma, Simon A Akpona, Jacques Simpore
The development of cervical cancer is associated with high-risk Human papilloma viruses (HPV-HR). In sub-Saharan Africa cervical cancer is the most common cancer among women and the leading cause of death attributed to malignant tumors. This study aims to identify HPV genotypes within the 30′S and 50′S HPV families found in two previous studie(...)

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(...)

Genetic diversity of Sclerocarya birrea subspecies birrea populations in Burkina Faso detected by RAPDs
PB Kando, C Bisseye, RK Nanema, ER Traore, H Ye, BO Diallo, TR Compaore, J Simpore, JD Zongo
Sclerocarya birrea, multipurpose plant is characteristic of the Sahel-Sudanian savanna and is widespread in West Africa. Although this species has a high socio-economic importance, its genetic organization was not well characterized in Burkina Faso. In this study, the intra and interpopulation genetic diversity of S. birrea was determined by r(...)

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(...)
