Study of the rheological properties of clayey suspensions: an interest in the field of landfills
Hamma Fabien Yonli, Anne Pantet, David Yemboini Kader Toguyeni
In the landfill bottom liners design process, geotechnical tests of long duration time are often conducted to ensure the presence of reactive clays and to assess their hydromechanical properties. This study aims to show the interest of the rheometry of clayey suspensions as an alternative tool for identifying clays and determining the shear st(...)

Perceptions and impacts of climate variability on livestock farming in The Gambia
Alpha Kargbo, Edrisa Jawo, Amien Isaac Amoutchi, Manjally Ndow, Abdoulie Bojang, Dabre Zainabou, Kumah Florence Jessica, Herve Kouakou Koua and Rex Kuye
Climate variability has had major health consequences for both humans and animals. A cross-sectional study was conducted in six administrative regions of The Gambia to respond to three questions: (i) what are the livestock farmers’ perceived occurrences and causes of climate variability? (ii) what are the perceived impacts of climate variabili(...)

OBTAINING OPTIMAL PARETO SOLUTIONS USING A HYBRID APPROACH COMBINING ε-CONSTRAINT AND MOMA-PLUS METHOD
Amidou Zoungrana, Kounhinir Somé, Joseph Poda
In this paper, we propose a new hybrid technique for nonlinear multi-objective optimization problems. This method combines the ε-constraint approach with the MOMA-Plus method. This involves using the ε-constraint technique to transform the initial problem into a single-objective one, instead of an aggregation function. The use of these functio(...)

Local perception of the current state and threat factors of a critically endangered species, Celtis toka (Forssk.) Hepper & J.R.I. Wood, in Burkina Faso: implications for species conservatio
Zaïnabou Dabré, Issouf Zerbo , Blandine Marie Ivette Nacoulma, Dodiomon Soro, Adjima Thiombiano
Celtis toka, the only species of the genus Celtis (family Cannabaceae) encountered in the flora of Burkina Faso, is critically endangered in the country. To engage the public for the future conservation and domestication of the species, knowledge of the factors threatening Celtis toka survival is necessary. Thus, the study objective was to ide(...)

Anaerobic co-digestion of agro-industrial cashew nut wastes with organic matters for biogas production: case of cashew nut hull and cashew almond skin
Joseph B. Sawadog, N. Bârsan, Mahamadi Nikiema, E. Moșneguțu, D. Dianou, A. Traoré, A. Ouattara, V. Nedeff
The cashew nut wastes (CNW), more released in the environment by cashew nut transforming units, are underused based on bioenergy. This study aimed at evaluating the biogas production by the anaerobic codigestion of CNW with various organic feedstocks. Physicochemical parameters and lower heating value (LHV) of cashew nut hull (CH) and cashew a(...)

Influence of topography on the natural stand structure of Boswellia dalzielii Hutch. in a semi-arid environment: Insight into hill ecosystems conservation in Burkina Faso
Prospère Sabo, Amadé Ouédraogo, Benjamin Lankoandé, Kolawolé Valère Salako, Hassane Ouédraogo, Romain Glèlè Kakaï
As the dominant woody species of some hills, the conservation of Boswellia dalzielii Hutch. could contribute to preserve vegetation of these azonal ecosystems, but also to restore degraded ones. However, given the topographical variation in hills, understanding the effects of such variation on the stand structure of B. dalzielii can assist the(...)

Isolation of Aspergillus flavus strains from Bambara groundnut (Vigna subterranea (L.) Verdcourt) seeds and screening for the production of aflatoxin B1 and B2
Amidou S. Ouili, Ynoussa Maiga, Mahamadi Nikiema, Inoussa Ilboudo, Fulbert Nikièma, A. Ouoba, H. Nandkangre, Cheik Omar Tidiane Compaoré, Elié Kabré, M. Ouédraogo, A. Ouattara
In Burkina Faso, Bambara groundnut is the second most important food legume after cowpea, especially in rural areas. However, this crop, due to certain conditions of production, storage or preservation is susceptible to be contaminated by potential mycotoxin producing fungi. The aim of this study was to evaluate the aflatoxinogenic capacity of(...)

Analyse du sens et des représentations des emprunts linguistiques dans les discours de campagne électorale de 2020 au Burkina Faso
NEBIÉ Boukary, BELEM Hamidou
Le discours politique a une forte visée persuasive, ce qui invite les hommes politiques à user de plusieurs stratégies pour influencer les électeurs en leur faveur. Au regard de leur bilinguisme ou multilinguisme, les hommes politiques ont recours aux expressions étrangères à leurs langues de communication dans la sphère politique burkinabè su(...)

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(...)

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(...)
