Application of the SBA method to solving optimal control problem governed by systems of nonlinear partial differential equations
Bakari Abbo, Pare Youssouf, Francis BASSONO, Marayi Choroma, Blaise Some
In this article, we are interested in solving optimal control problems governed by a system of nonlinear partial differential equations by the iterative method SBA(combination of the Adomian method, successive approximations method and the principle of Picard) ]. This technique allows reducing the problem of optimal control of the error

Insecticide resistance in Bemisia tabaci Gennadius (Homoptera: Aleyrodidae) and Anopheles gambiae Giles (Diptera: Culicidae) could compromise the sustainabilit...
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 on cotton), has caused insecticide(...)

Soil-Water Characteristic Curve Modeling at Low Water Content: Empirical and Semi-Empirical Approaches
Marcel Bawindsom Kebré, François Ouédraogo, Naon Betaboalé, Francois Zougmoré, Fabien Cherblanc
In this paper, we evaluate the performance of the most widely used semi-empirical models (van Genuchten (1980), Fayer and Simmons (1995) and Fredlund and Xing (1994)) and, an empirical model, the Modified Kovacs (MK) model for the determination of soil-water characteristic curve at the low water contents of two horizons of a soil from Burkina(...)

« The Symbolic Use of Palm, Figurines, and Hibiscus in Adichie’s Purple Hibiscus»
André Kaboré
Chimamanda Ngozi Adichie uses many symbols in her novel, Purple Hibiscus. An explanation of these symbols will lead readers to a deeper understanding of the message of the author. This paper focuses mainly on the symbols of palm, figurines and hibiscus which are used in Purple Hibiscus. It argues that these symbols represent some characters in(...)

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(...)

Molecular characterization of genetic diversity within the Africa/Middle East/Asia Minor and Sub-Saharan African groups of the Bemisia tabaci species complex
Bemisia tabaci Gennadius is a major plant pest in many agricultural systems worldwide. It is a complex of cryptic species that differ in many ecological respects, including damage-causing potential. Monitoring the genetic composition of B. tabaci populations in the field is, therefore, essential for achieving effective control. Sequencing is c(...)

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(...)

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(...)
