Sampling Geostatistical Structures in Extremal Framework
Fabrice Ouoba, Hay Yoba Talkibing, Diakarya Barro.
Geostatistics of extreme values makes it possible to model the asymptotic be-havior of random phenomena that depend on time or space. In this paper, wepropose new models of the extremal coefficient of a stationary random fieldwhere the cumulative distribution is associated with a multivariate copula.More precisely, some models of extensions of(...)

Antimicrobial Activity of Bacterial Strains Isolated from Macrotermes belli-cosus Termite Mound
Benewinde' Sawadogo, Sandrine T. E. Hien, D. Palé, Ynoussa Maiga, Mahamadi Nikiema, Illiassou Mogmenga, Yérobessor Dabiré, C. Ouattara, A. Ouattara
Natural environments like termite mounds can be a reservoir for novel microbial strains and antimicrobial metabolite producers. Hence, this study aimed to investigate the antimicrobial activities of bacterial strains isolated from Macrotermes bellicosus (M. bellicosus) termite mound materials. These materials were sampled from active termite m(...)

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 optimization 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 the b(...)

Porome folliculaire atypique du cuir chevelu : présentation d’un cas avec revue de la littérature
WSPA Yameogo, DS Zabsonre, S Ouattara, F Traore, A Kabre
Introduction : Le porome folliculaire ou kératose folliculaire inversée est une tumeur bénigne des annexes cutanées développée au dépend du follicule pileux. Il est difficile de faire son diagnostic clinique. Le diagnostic est confirmé par l’examen anatomo-pathologique. Nous rapportons le cas d’une forme atypique de porome folliculaire du cuir(...)

Production of Vinegar Mango Using <i>Acetobacter tropicalis</i> CRSBAN-BVA1 and CRSBAN-BVK2 Isolated from Burkina Faso
Assiètta Ouattara, M. Somda, C. Ouattara, Yérobessor Dabiré, Mahamadi Nikiema, A. S. Traoré, A. Ouattara
Production and quality of vinegar from mango juice was evaluated using a two steps production procedure. The first step of fermentation was done using Saccharomyces cerevisae KVL013 for 7 days. The second step, an acetic fermentation was realized using two acetic acid bacteria: A. tropicalis CRSBAN-BVA1 and A. tropicalis CRSBAN-BVK2 for 21 day(...)

Post-Harvest Fungi Associated with Cowpea (<i>Vigna unguiculata</i> L. Walp.) Seeds Produced in Burkina Faso
Amidou S. Ouili, Ynoussa Maiga, Mahamadi Nikiema, Souleymane Bissiri, Yérobessor Dabiré, Illiassou Mogmenga, Cheik Omar Tidiane Compaoré, A. Ouattara
Cowpea is a very popular foodstuff among people in sub-Saharan Africa. In Burkina Faso, it is the main food legume, especially in rural areas. Its production is facing difficulties including post-harvest losses caused by fungi. Therefore, the objective of this study was to isolate and identify fungal strains associated with cowpea seeds produc(...)

Assessment of Maize Contamination by Aflatoxin in Burkina Faso: A Review of Methods of Control
M. Somda, Yérobessor Dabiré, Iliassou Mogmenga, Assiètta Ouattara, Mahamadi Nikiema, Henriette B. Mihin, Agbémébia Y. Akakpo, Donatien Kaboré, A. Traoré, Mamadou Dicko
Aflatoxin contamination of crops is frequent in warm regions across the globe, including large areas in sub-Saharan Africa and Burkina Faso. A?atoxins and fumonisins are among the mycotoxins that have been increasingly reported to affect health and productivity of livestock globally. It cuts across the value chain, affecting farmers, markets,(...)

Thermal Effect of Braking on Pavements during Heat Waves in Ouagadougou
Sidpouita Mathilde Koudougou, Hamma Fabien Yonli, Moussa Sougoti, David Yemboini Kader Toguyeni
Flexible pavements, whose surface layers are made from hot mix asphalt, may show rutting in some of these infrastructures during the first months of life. In the city of Ouagadougou, this rutting phenomenon is sometimes observed. The objective of this article is to quantify the thermal response of the wearing course of national roads 1 and 2,(...)

Contribution of Electrical Resistivity Tomography to the Anticipation of Potential Disasters: Case of Pipe Ramming Works Under Road Embankments
Hamma Fabien Yonli, Mahamadou Koïta, Issouf Kanla, Aristide Compaoré, Gilbert Mano
Throughout Burkina Faso's road network, some roadways have experienced subsidence or collapse following pipe ramming works conducted for the laying of pipes such as drinking water supply networks.When such works are conducted, it is difficult to make a diagnosis of the properties of the formations underlying the road embankment because a destr(...)

Épreuve et argumentation dans les discours panafricanistes : stratégies d’une (con)quête en questionnement
BELEM Hamidou
Les discours sont l’expression d’une certaine activité à l’image des récits. Ils permettent à leur sujet de faire faire des transformations passant d’une situation donnée à une autre. Aussi, des stratégies argumentatives y sont déployées à l’effet de persuader ou de convaincre les interlocuteurs. Le présent article se donne pour objectif d’ana(...)

CONVERGENCE OF THE SIMPLE EXACT BARRIER-PENALTY FUNCTION FOR NONLIEAR MULTIOBJECTIVE OPTIMIZATION
A. Compaoré, Kounhinir Somé, Joseph Poda
In this paper, an extension of the new barrier penalty technical is proposed. Initially, design for nonlinear single-objective optimization with inequality constraints, we have transformed it for solving nonlinear multiobjective optimization problems with inequality constraints. First, we have provided the theoretical foundations for this exte(...)

Hydrogeophysical Characterization of a Fractured Aquifer by Using Cumulative Resistivity Method: Case Study of Obuasi Aquifer (Ghana)
Hamma Fabien Yonli, Mahamadou Koïta, Younaise Sounkanmi Olouwachéyi Adéotan, Elisabeth Darko
Knowledge of the structure and geometry of aquifers is an important prerequisite when one wishes to sit a borehole. Such knowledge is currently obtained by VES (Vertical Electrical Soundings) whose interpretation is not always unequivocal in the sense that several resistivity models derived from VES can explain the same data set. The present s(...)

Description of the subject. The fall armyworm Spodoptera frugiperda Smith has recently invaded sub-Saharan African countries where it causes significant losses to maize since 2016. Objectives. In this study, we examined farmers' knowledge of the fall armyworm, changes in pest management practices, and the safety of insecticide use by farmers s(...)
