Periodic solutions in the α-norm for some partial functional differential equations with finite delay.
K. Ezzinbi, B.A. Kyelem, S. Ouaro
The paper deals with the partial functional differential equation with finite delay in the α-norm
dudt(t)=−Au(t)+f(t,ut),t∈ℝ,
where f:ℝ×Cα→X is a continuous function, σ-periodic in the first argument, A:D(A)⊂X→X is a linear operator, −A is the infinitesimal generator of an analytic semigroup of linear operators (T(t))t≥0 on a Banach space X,(...)

Antipassivating electrochemical process of glassy carbon electrode (GCE) dedicated to the oxidation of nitrophenol compounds
M. Pontié, G. Thouand, F. De Nardi, I. Tapsoba, S. Lherbette
We report for the first time a novel electrochemical treatment applied to a glassy carbon electrode (GCE) during p‐nitrophenol (PNP) oxidation and dedicated to the limitation of electrode passivation by nitrophenol compounds oxidation. We propose an electrochemical process of direct phenol oxidation by starting the electrolysis at a very low p(...)

HI and Hα Mapping of M31 & M33
Z. S. Kam , C. Carignan , L. Chemin , O. Hernandez , M. de Denus-Baillargeon and Y. Djabo
We performed a deep HI and Hα mapping of M31 and M33 in order to get accurate kinematical data of those two galaxies and also to make a comparison between the HI and Hα kinematics. The HI data were obtained with the DRAO interferometer and the Hα data with the Fabry-Perot system of the Observatoire du mont Mégantic using an EMCCD as a detector(...)

Exclusive formula feeding, exclusive breastfeeding (EBF) with early weaning or the administration of antiretroviral therapy to lactating mothers and/or to breastfed newborns may lower postnatal HIV transmission. The aim of this study was to assess mothers' knowledge, attitudes and practice (KAP) on lactation in various real-life settings in su(...)

Impact of land use types on population structure and extent of bark and foliage harvest of Afzelia africana and Pterocarpus erinaceus in Eastern Burkina Faso
Blandine Marie Ivette Nacoulma, Salifou Traoré, Karen Hahn and Adjima Thiombiano
In the West African Sudanian regions, people depend on natural products, especially on highly valued species as source of income, fuel wood, food, medicine, fodder for livestock etc. However, land-use management coupled with unsustainable uses of highly valued trees might jeopardize the long-term viability of some speciesrsquo; populations.

Experimental characterisation and modelling of thin layer solar drying of amelie and brooks mangoes
A. O. Dissa, J. D. Bathiebo, H. Desmorieux, O. Coulibaly; J. Koulidiati
Direct solar drying characteristics of Amelie and Brooks mangoes were experimentally determined using a solar dryer made up of four trays and used under weather conditions of fruit harvest period. Direct solar drying curves were established, fitted using 10 mathematical models and simulated with a direct solar drying model. Effective diffusivit(...)

Médiation et gestion des conflits. Essais sur les fins et les moyens pacifiques de sortie de crise
Koné Cyrille B
Les textes de l'ouvrage repensent l'Etat au-delà de ses capacités immédiates à conférer, à pérenniser des droits et de mener la puissance d'intelligibilité des concepts éthiques, juridiques, politiques, anthropologiques, économiques et philosophiques, hors des jeux connus du pardon et de l'impardonnable, vers de nouvelles compréhensions du don(...)

An ethnobotanical study of antimalarial plants in Togo Maritime Region
K Koudouvo, D S Karou, K Kokou, K Essien, K Aklikokou, I A Glitho, J Simpore, R Sanogo, C De Souza, M Gbeassor
Background: Malaria continues to be of great concern in Togo, as it accounts for high mortality rates, principally in children. Although plant-based medicines are the only means in major malarious regions of the country, still very little is known about the medicinal plants and medical practices of the indigenous people.
Objective: The pres(...)

Background
Approximately, 15–20 of 40 HPVs that infect the female genital tract confer a high-risk of invasive cancer, thus HPVs account for 95% of cervix cancers. The objectives of this study were to: (i) estimate the prevalence of HPV infection in women infected with HIV in Ouagadougou, (ii) identify potential carcinogenic HPV strains and ((...)
