Effective Factors on Acute Malnutrition in Children Aged 6 to 59 Months in the Centre-West Region of Burkina Faso
Jeanne d’Arc Kabre; MSc 1 , Sibiri Bougma; MSc 1 , Bassibila Zoungrana; MSc 1 , Yves Traoré; PhD1 & Aly Savadogo; PhD*1
In Burkina Faso, malnutrition is a public health problem. Despite
the significant drop in the prevalence of malnutrition since 2009 according to
the Directorate of Nutrition, malnutrition is still a major concern with regard to
its consequences. The objective of this study was to determine the factors
associated with acute malnutrition(...)

A global mathematical model of malaria transmission dynamics with structured mosquito population and temperature variations
TRAORE Bakary, KOUTOU Ousmane, SANGARE Boureima
In this paper, a mathematical model of malaria transmission which takes into account the four distinct mosquito metamorphic stages is presented. The model is formulated thanks to the coupling of two sub-models, namely the model of mosquito population and the model of malaria parasite transmission due to the interaction between mosquitoes and h(...)

Genetic polymorphisms of certain classes of glutathione S-transferase (GST), enzyme responsible for the biotransformation of drugs and xenobiotics, have been associated with risk of several cancers such as cervical cancer. The aim of this study is to investigate the impact of glutathione S-transferase M1 and T1 deletion on high-risk human papi(...)

In vitro Antihyperglycemic and Chelating Potential of Selected Ayurvedic Medicinal Plants
Ahmed Coulibaly, Riaz Hashim, Pierre Alexandre Eric Djifaby Sombié, S. F. Sulaiman, Othman Sulaiman, Lily Zuin Ping Ang, Kheng Leong Ooi, Martin Kiendrébeogo
Seven medicinal plants used in folk medicine to relieve various diseases including diabetes, were investigated for antihyperglycemic activities. Two types of extracts for each plant were processed by decoction and by soaking in an aqueous-acetone mixture. The inhibitory activities were tested on α-amylase and α-glucosidase along with chelating(...)

Modulating the electrical properties of organic heterojunction devices based on phthalocyanines for ambipolar sensors
Seydou Ouedraogo, Rita Meunier-Prest, Abhishek Kumar, Mabinty BayoBangoura, and Marcel Bouvet
Although ambipolar materials are highly studied in organic electronics, they are rarely used in gas sensors. In
the present work, we studied ammonia sensing on organic heterojunctions in a bilayer configuration composed of
octachlorinated metallophthalocyanines (M(Cl8Pc); M: Co, Cu and Zn) as a sublayer and lutetium bis-phthalocyanine (LuPc2(...)

Calculation of the Chemical Composition of Air - PMMA Mixtures Thermal Plasmas
Kagoné Abdoul Karim*, Kohio Nièssan, Yaguibou Wêpari Charles, Koalaga Zacharie, Zougmoré François
Knowledge of the chemical composition of plasma is necessary for calculations and modeling in thermal plasmas. Indeed, from the knowledge of this composition we can calculate the thermodynamic properties, the transport coefficients and the radiative properties of a plasma medium. In this work, we propose to study at thermodynamic equilibrium t(...)

Existence and regularity of solutions in α-norm for some partial functional integrodifferential equations in banach Spaces
Issa Zabsonre, Djendode Mbainadji
In this work, we study the existence and regularity of solutions in α-norm for some partial functional integrodifferential equations in Banach spaces. We suppose that the undelayed part admits a resolvent operator, the delayed part is assumed to be locally lipschitz. Firstly, we show the existence of mild solutions. Secondly, we give sufficien(...)

NUMERICAL STUDY OF HEAT AND MASS EVAPORATION-BASED BASED TRANSFERS IN A LARGE DIMENSION RESERVOIR: THE INFLUENCE OF METEOROLOGICAL PARAMETERS AND RAYLEIGH
BAYALA Alfred1, TUBREOUMYA G. Christian3, BORO Drissa1, IMBIDA B. Kossi1, BADO Nebon1, ZEGHMATI Belkasem2, KIENO P. Florent1 and BATHIEBO Joseph
A numerical study of heat and mass transfers in a large water reservoir is presented. This water reservoir is being considered as a parallelepiped tank which vertical and lower walls are adiabatic and impermeable. The equations that govern the natural convection in water are solved using the finite volume method and Thomas algorithm. The adequ(...)

Private and public investment in sub-Saharan Africa: The role of instability risks
Ouédraogo, Rasmané & Sawadogo, Relwendé & Sawadogo, Hamidou
This paper explores the impact of public investment on private investment in sub-Saharan Africa using the finite mixture model. We argue that the impact of public investment on private investment differs across groups of countries with similar but unobserved characteristics. Contrary to previous studies, the paper incorporates the potential pr(...)

Hydrogeochemical and pollution characterization of a shallow glauconitic sandstone aquifer in a peri‑urban setting of Bobo‑Dioulasso, southwestern Burkina Faso.
Aboubakar Sako, Sâga Sawadogo, Mamadou Nimi, Mahamadou Ouédraogo
Groundwater resources are often exposed to multiple sources of pollution, which may make them unfit for human consumption. As a result, comprehensive geochemical studies on groundwater status and evolution are required for a sustainable management of water resources. In the present study, 38 water samples from hand-dug wells were collected in(...)
