Structural controls of the expansion of small‐scale artisanal gold of Bouda area (Kaya‐Goren Green Belt, Burkina Faso) from remote sensing
R. A. I. Dao, H. Ilboudo, and D. Baratoux
Small‐scale artisanal mining is a vital sector of the economy of Burkina Faso. This activity, correctly regulated, remains essential for the population despite security issues since 2015. Exploration of new areas for gold mining in this condition is difficult but essential to continue extractive activities. It is, therefore, important to defin(...)
Bouda is an artisanal and small‐scale mining district in Burkina Faso, Remote sensing using Landsat images allowed us to study the structural control of the expansion of the Bouda site, Remote sensing using Landsat images allowed to define future exploitation corridors of the Bouda site

Déterminants du choix des énergies de cuisson des ménages de la ville de Ouagadougou au Burkina Faso
Djièta Zougouri, Wendyam Assumpta Missa Sawadogo et Tibi Didier Zoungrana
Le présent travail s’appuie sur des données primaires collectées auprès de 385 ménages de la ville de Ouagadougou et cherche à analyser les déterminants du choix des énergies de cuisson par les ménages en insistant sur la prise en compte de l’environnement. Pour ce faire, nous avons eu recours au modèle probit bi-varié. De l’analyse effectuée,(...)

PERFORMANCE STUDY OF MULTIOBJECTIVE OPTIMIZER METHOD BASED ON GREY WOLF ATTACK TECHNICS30
Wendinda Bamogo, Kounhinir Some, and Guy Aymard Degla
This paper proposes a performance study for the Multiobjective Op-
timizer based on the Grey Wolf Attack technics (MOGWAT). It is a method of
solving multiobjective optimization problems. The method consists of the reso-
lution of an unconstrained single objective optimization problem, which is de-
rived from the aggregation of objective f(...)

Investigating the weak and semi strong forms of informational efficiency on the West African Economic and Monetary Union’s stock market through returns predictability tests
Daouda Lawa Tan TOE, Mamadou TOE, Tibi Didier ZOUNGRANA
This study uses data from the BRVM and BCEAO databases collected between 1998 and 2020 to analyze the weak and semi-strong forms of the informational efficiency in the BRVM exchange. To examine the weak form of efficiency, the Augmented Dickey Fuller test, the Runs test, and the variance ratio are used. For the semi-strong form, the Johansen ((...)

New lithological and structural data from the Nindangou area in the eastern portion of the Goren belt (Burkina Faso - West Africa)
Rashid Ali Isdine Dao, Hermann Ilboudo & Séta Naba
The eastern portion of Burkina Faso, including the Nindangou area, was covered by mapping after independence in order to promote geology and identify favorable sites for useful mineral resources. However, the majority of geological maps are limited to the spatialization of lithological units without paying attention to structural and lithostra(...)

Contribution of non-timber forest products to food security of households bordering the Pô-Nazinga-Sissili ecological complex in Burkina Faso
Soumaïla Sawadogo
The current paper analyses the contribution of non-timber forest products (NTFPs) to households' food security bordering the complex Pô-Nazinga-Sissili, a protected area in south Burkina Faso. Using primary data from a sample of 263 randomly selected households, two food security indicators, the Household Dietary Diversity Score and the Househ(...)

A note on generalized inner derivations of Hom-Lie triple systems
Hamdiatou Yara, Patricia L. Zoungrana
Nous étudions les dérivations généralisées des systèmes triples Hom-Lie. Plus précisément nous introduisons la notion de α^k-dérivations intérieures de systèmes triples Hom-Lie et nous établissons quelques propriétés. Dans le cas où le corps K est de caractéristique non nulle p, nous montrons que la p-ème composée d’une α^k-dérivation d’un sys(...)

Digital and institutional social networks: between tension and adaptation to ensure pedagogical continuity in higher education, before, during and after the health crisis of March 2020
Marc Trestini, Isabelle Rossini, Dimkêeg Sompassaté Parfait Kabore
The unexpected situation caused by the COVID-19 pandemic forced an immediate shift to
distance learning (DL) for all courses in order to ensure educational continuity at
French universities on Saturday, March 14, 2020. In the absence of suitable institutional tools at the start of the
first lockdown, instructors had to quickly find technica(...)

Grey wolves attack process for the Pareto optimal front construction in the multiobjective optimization
Wendinda Bamogo, Kounhinir Somé, Joseph Poda
We propose a new metaheuristic, HmGWOGA-MO, for solving multiobjective opti-
mization problems operating with a population of solutions. The method is a hybridization of
the HmGWOGA method, which is a single objective optimization method, and the ϵ-constraint
approach, which is an aggregation technique. The ϵ-constraint technique is one of(...)

On restricted Hom-Lie triple systems
Hamdiatou Yara, Patricia L. Zoungrana
Nous étudions le concept de systèmes triple Hom-Lie restreints vus comme une généralisation de celui des systèmes triple de Lie restreints. Nous avons principalement montré que pour tout système triple Hom-Lie régulier (T, [,,], α) de centre nul, si l'algèbre de Lie enveloppante (LT, [,]LT, [p]) est restreinte alors (T, [,,], α, [p]) est un s(...)

Impacts of organic and inorganic input usage on agricultural productivity in Burkina Faso in a security crisis
Aimé Okoko, Tibi Didier Zoungrana
Sub-Saharan Africa faces food insecurity, worsened by rapid population growth outpacing agricultural output. Inorganic fertilisers offer potential solutions, but their current low usage is insufficient to meet food demands. This study explores the impact of inorganic fertiliser use on agricultural productivity in Burkina Faso, using data from(...)
