On exponential stability of mild solution of a stochastic integrodifferential equation in a complex Hilbert space
Wahabo BAGUIAN; Victorien KONANE; Claude YAMEOGO
In this work, we consider a system of stochastic integrodifferential
equations in a complex Hilbert space. We first establish the existence
and uniqueness of mild solutions for equation (1) under non-Lipschitz
conditions. Then we show under certain assumptions that the found
mild solution is exponentially stable on average of order n. Note(...)

Characteristics of Patients with Sickle Cell Anaemia Admitted to the Bogodogo University Hospital’s Pediatric Unit in Ouagadougou, Burkina Faso, between 2017 and 2021
Sawadogo, A.-G., Sawadogo, S., Saré, S., Bilgo, A., Nebié, K., Konseybo, A., Ouédraogo, P., Zagré, N. and Ouédraogo, Y.S
Introduction: Sickle cell anaemia, the most widespread genetic disease in the
world, is an autosomal recessive hereditary disease characterised by the substitution
of glutamic acid for valine in position 06 of the globin beta chain, giving
rise to this aberrant haemoglobin S. The aim of this study is to determine the
characteristics of pat(...)

Plant material yield evaluation for hepatoprotective plant rational use in Burkina Faso, West Africa
Souleymane Compaoré, Tata Kadiatou Traoré, Lazare Belemnaba, Salfo Ouédraogo, Noufou Ouedraogo, Sylvin Ouedraogo and Adjima Thiombiano
This study aims to contribute to the sustainable use of plant resources. Thus, 38 species with hepatoprotective potential were sampled in several locations of Burkina Faso between May and October 2021. These species were identified during previous surveys with traditional healers. These plants' leaves, roots, and trunk barks were collected and(...)

Water and its biological resources sustainability in tropical developing countries: aquatic ecosystems health assessment
Idrissa Kaboré , Otto Moog , Adama Oueda, Andreas Melcher
To response to ongoing threats from human pressures and climate changes, water managers and users need a visual tool that provide accurate information of waterbodies health
for decision making to promote sustainable management practices. However, there is a lack of less sophisticated tools, such as biotic score, to assess the health of aquati(...)

Corrective Effect of the Angle of Incidence of the Magnetic Field Intensity on the Performance (Series and Shunt Resistances) of a Bifacial Silicon Solar Cell
Idrissa Sourabié, Mahamadi Savadogo, Boubacar Soro, Ramatou Saré, Christian Zoundi, Martial Zoungrana, Issa Zerbo
This article presents a three-dimensional analysis of the impact of the angle of incidence of the magnetic field intensity on the electrical performance (series resistance, shunt resistance) of a bifacial polycrystalline silicon solar cell. The cell is illuminated simultaneously from both sides. The continuity equation for the excess minority(...)

Mullite effect on the ceramic filters effectiveness in the removal of arsenic from borehole water from Burkina Faso
Kassoum Barry, Gisele Laure Lecomte-Nana, Nassio Sory, Moussa Ouedraogo, Loukou Sawadogo, Moustapha Sawadogo, Issaka Sanou, Mohamed Seynou, Lamine Zerbo, Philippe Blanchart
The intrinsic technological characteristics depend on the forming process and the application for which the
materials are intended. A clay raw material (75 mass%) which is rich in melting oxides and waste peanut shells
(25 mass%) were used to manufacture porous ceramics for the removal of arsenic from borehole water in Burkina
Faso. A bo(...)

Introduction: Bacterial meningitis done represent a major public health concern especially within the meningitis belt. In 2019, Hemophilus influenzae (Hi) was responsible for 8% of meningitis cases in the ECOWAS zone. In Burkina Faso, the vaccine against type b Hi was introduced in the broad vaccine program since 2006. The purpose of this stud(...)

Transitionning and the trinity nexus: Scenarios from a small country
Abdoulganiour Almame Tinta
The energy issue in both developed and developing countries remains vital. However, in developing countries, energy pressure is much greater. Despite this, few studies have examined credit, entrepreneurship, and energy transition in developing countries. We addressed this research gap by using the data collected from six regions in Burkina Fas(...)

Dynamics of a SVEIR Epidemic Model with a Delay in Diagnosis in a Changing Environment
Hamadoum Dicko, Ali Traoré, Désiré Ouedraogo
SVEIR epidemic model with a delay in diagnosis is studied in a constant and variable environment. The mathematical analysis shows that the dynamics of the model in the constant environment are completely determined by the magnitude of the delay-induced reproduction number Rα. We established that if Rα<1, the disease-free equilibrium is globall(...)

Numerical Modelling of Coupled Heat and Mass Transfer in Porous Materials: Application to Cinder Block Bricks
Benjamin Kiema , Ousmane Coulibaly and Xavier Chesneau, Belkacem Zeghmati
In this work, we present numerical modelling of coupled heat and mass transfer within porous materials. Our study focuses on cinder block bricks generally
used in building construction. The material is assumed to be placed in air. Moisture content and temperature have been chosen as the main transfer drivers
and the equations governing these(...)
