Advanced dependence metrics and tail coefficients in a bounded copula construction
HERMAN TIEMTORÉ , REMI GUILLAUME BAGRÉ, AND VINI YVES BERNADIN LOYARA
In this work, we study some properties of the family of copulas introduced previously by Bagré et al. We discuss from dependence metrics such as Spearman's rho, the medial correlation coefficient and distances separating this family of copulas from the Fréchet bounds (lower and upper bounds) and the product copula, respectively. The tail coeff(...)

Research on Sweet Potato (Ipomoea batatas) in West Africa: State, Features and Gaps
Hamid El Bilali, Romaric Kiswendsida Nanema, Veli-Matti Rokka, Iro Dan Guimbo, Zakaria Kiebre, Rosa Anna Siciliano, Sheirita Reine Fanta Tietiambou, Lawali Dambo, Jacques Nanema, Francesca Grazioli and Filippo Acasto
Although sweet potato (Ipomoea batatas) is gaining importance in West Africa, it remains uncertain whether the research is adequately advanced to support the promotion
of this crop in the region. Consequently, this systematic review of 125 articles provides a detailed overview of studies focused on sweet potatoes in West Africa. The paper exp(...)

Improving the Bearing Capacity of Road Soil by Treatment with Cement and Lime: Case of National Road No. 4 in the City of Ouagadougou in Burkina Faso
Bernard Gouba, Boukari Sawadogo, Dieudonné Dabilgou
Nowadays, the question of the availability of good quality materials is increasingly raised in road projects. This has led us to techniques for improving the performance of materials that can be used in road layers. Cement and lime treatment is a well-known technique for improving materials in road construction. The test is done by adding a sm(...)

Wetlands of Burkina Faso: Biodiversity, Livelihoods, and Conservation
Kaboré Idrissa, Bancé Victor, Konaté Sidiki Roland, Sawadogo Yabyouré Marc-Florent, Ouéda Adama
West-African wetlands support the biodiversity and the local population livelihoods, but they are heavily threatened by multiple pressures. However, research and inventory studies on wetlands are still less documented. To do so, we investigated on the biodiversity, the livelihoods, and conservation measures of two wetlands in Burkina Faso. Wet(...)

Existence and regularity of solutions in α-norm for Some second order partial neutral functional Differential equations with finite
DJENDODE MBAINADJI, SYLVAIN KOUMLA AND ISSA ZABSONRE
The purpose of this work is to investigate the existence and regularity of solutions in the α-norm for some second order partial neutral functional differential equations in Banach
spaces with finite delay using fractional -power and the theory of the cosine family. As result, we obtain a generalization of work of Herman R. Henriquez et al.(...)

Cholera invasion speed and the intervention strength
Komi Afassinou, Ousmane Koutou, Narcisse Roland Loufouma Makala
We formulate a mathematical model which captures the essential dynamics of cholera infection transmission. Control interventions such as vaccination program and environmental sanitation service are incorporated to analyse the impact of both interventions on the infection dynamics. The qualitative and numerical analyses of the model are carried(...)

Premier inventaire des macroinvertebres du fleuve Niger à Faranah en Guinée
Aïssatou Lamarana Bah, Idrissa Kabore, Lanciné Sangare, and Abdoulaye Barry
En Guinée, les ressources en eau subissent une pression anthropique. Les changements dans la qualité de l’eau peuvent avoir un impact sur la composition de la faune aquatique. A ce jour cette faune est pratiquement inconnue au fleuve Niger en Guinée. Notre recherche a été menée sur un parcours de 10 Km du fleuve au Centre-ville de Faranah. L’o(...)

Towards a framework for monitoring crop productivity in agroforestry parklands of the Sudano-Sahel using Sentinel-1 and 2 time series
Julianne Oliveira, Martin Karlson, Abraham Sotongo Ouédraogo, Hugues Roméo Bazié, Madelene Ostwald
The agroforestry parklands in the Sudano-Sahelian zone are of critical importance for food security, but face several challenges in terms of changes in climate and land use. The ability to systematically monitor crop productivity in these systems is therefore of importance for both informing land management policies and studying long-term tren(...)

Microbiological, Biochemical and Physicochemical Characterization of Water Quality and Islands (Domoro and Maguite) in Lake Fitri, Chad
Djibrine Adoum Oumar, Hama Cissé, Atteib Adam Baye, Adama Sawadogo, Jacques Etame, Abdelsalam Tidjani, Savadogo Aly
A total of fifty (50) samples of water from Lake Fitri (Chad), with 25 samples per island (Domoro and Maguite). The aim of this study was to analyze the bacteriological, biochemical and physico-chemical quality of the water in Lake Fitri in Chad. Standard microbiology methods were used. Isolated strains of enterobacteria were characterized by(...)

General practitioners’ knowledge of psychotraumatism in Burkina Faso in a context of security challenges
Konsam Cédric Christel Sawadogo , Boubacar Bague , Adama Galboni , Mahamane Mobarak Salifou Abdou , Zeinabou Cisse and Kapouné Karfo
Post-traumatic stress disorders are psychiatric disorders that arise after a traumatic event. They result in moral
suffering and physical complications that profoundly alter personal, social and professional life. Our main objective
was to study general practitioners (GP)’ knowledge of psychotraumatism. This was a descriptive, cross-sectio(...)

Les radios communautaires au Burkina Faso face à la crise sécuritaire : Contraintes, adaptations et résiliences
Esther Delwendé Konsimbo, Boukari Ouédraogo
L'insécurité qui secoue le Burkina Faso depuis 2015 a modifié les pratiques journalistiques et le rôle des radios communautaires au Burkina Faso. Cet article analyse comment les radios communautaires font face aux défis liés à la crise sécuritaire. L'article s'appuie sur la théorie du gatekeeping comme cadre d'analyse. A partir d'entretiens av(...)

Transition frequency and dynamic of polaron in transition metal dichalcogenide under radiowave and microwave
J. V. Nguepnang, C. Kenfack-Sadem, Mboumba Maik Delon, M. R. Kamsap, A. Kenfack-Jiotsa, Bokoyo Barandja Vinci De Dieu, I. Zerbo
We investigated the transition frequency and dynamic of polaron in transition metal dichalcogenide (TMD) under the radiowave and the microwave using Pekar variational method. We calculated the ground and first excited states energies of polaron, the magnitude of the bandgap modulation, the mobility and the lifetime of polaron are derived. Due(...)

Evolution des pratiques endogènes dans les communes rurales du nord du Burkina Faso
Yasmina Téga, Hycenth Tim Ndah, Eveline Compaoré-Sawadogo, Jean-Marie DIPAMA, Johannes Schuler
Au Burkina Faso, on constate une dégradation importante des sols liée à une gestion insuffisante des éléments nutritifs et à des pratiques agricoles inadaptées aux conditions climatiques et pédologiques. Les pratiques d’agroécologie sont des solutions endogènes permettant de répondre à ces défis. L’objectif de cette recherche est d’analyser l’(...)

Forage harvesting using branch pruning compromises sustainable use and conservation of Pterocarpus erinaceus Poir., an endangered species
Bossila Séraphin Hien, Loyapin Bondé, Mohamed Mahamoud Charahabil, Sié Sylvestre Da, Joseph Issaka Boussim, Oumarou Ouédraogo
Pterocarpus erinaceus Poir. is a leguminous tree species with huge forage value. It is subjected to heavy pruning pressure in dry season for livestock feeding, resulting in yearly decline of forage production and vulnerability of the species which is currently classified as endangered species. This study aimed at: (i) identifying factors influ(...)
