Assessment of CH4 and CO2 surface emissions from Polesgo's landfill (Ouagadougou, Burkina Faso) based on static chamber method
Kayaba Haro, Issoufou Ouarma, Bernard Nana, Antoine Bere, Guy Christian Tubreoumya, Sié Zacharie Kam, Patricia Laville, Benjamin Loubet, Jean Koulidiati
Methane (CH4) and carbon dioxide (CO2) surface emissions from Polesgo's landfill (Ouagadougou, Burkina Faso) were measured using the static chamber technique in 2017 and 2018. The Polesgo's landfill was composed of four zones: Phase I, II, Phase III, and SP. The surface of Phase I was fully covered and its conditions are better for surface emi(...)

Bifurcation and stability Analysis in Complex Cross-Diffusion Mathematical Model of Phytoplankton-Fish Dynamics
OUEDRAOGO Hamidou, OUEDRAOGO Wendkouni and SANGARE Boureima ´ ∗
In this paper, we propose a nonlinear reaction-diffusion system describing the interaction
between toxin-producing phytoplankton and fish population. We analyze the effect of cross-diffusion on
the dynamics of the system. The mathematical study of the model leads us to have an idea on the existence
of a solution, the existence of equilibria(...)

Toddlers’ Dietary Diversity and Its Determinants in Different Agricultural Periods
Ouédraogo, Ousmane, Ella Wendinpuikondo Raketa Compaoré, Emile Kou’santa Sabiba Amouzou, Mamoudou Hama Dicko
Background: Inadequate diet and illness were immediate causes of malnutrition. Dietary diversity helps to ensure adequate intake of essential nutrients and promotes good health. Challenge is to maintain adequate nutrients intake during all periods. The primary study objective was to determine the toddlers’ dietary diversity and its determinant(...)

Wild and cultivated biomass supply chain for biofuel production. A comparative study in West Africa
Linda Dominique Fabiola Bambara, Marie Sawadogo. Daniel Roy, Joël Blin, Didier Anciaux, Salifou Koucka Ouiminga
Limited access to energy has led to interest in biofuels in most West African countries where jatropha curcas (Jatropha) has been the most widely studied energy crop. However, due to difficulties in obtaining enough jatropha seed at acceptable costs, Balanites aegyptiaca (B. aegyptiaca) could be an alternative feedstock for biofuel production(...)

Liver retinol estimated by 13C-retinol isotope dilution at 7 versus 14 days in Burkinabe schoolchildren
Jean F Bationo , Augustin N Zeba , Nadine D Coulibaly , Jesse Sheftel , Christopher R Davis , Imael HN Bassole , Nicolas Barro , Jean B Ouedraogo and Sherry A Tanumihardjo
Vitamin A status assessment is not straightforward. Retinol isotope dilution (RID) testing requires time for the tracer dose to mix with the total body stores of vitamin A (TBS). Researchers are interested in shortening the time interval between tracer administration and follow-up blood draws, and in re-examining current assumptions about live(...)

Antioxidant capacity and behavioral relevance of a polyphenolic extract of Chrysanthellum americanum in a rat model of irritable bowel syndrome
Roxana Cojocariu, Alin Ciobica, Ioana-Miruna Balmus, Samson Guenne, Anca Trifan, Carol Stanciu, Luminita Hrițcu, Radu Lefter
Chrysanthellum americanum L. (Vatke) is a medicinal plant from the Compositae family used in west-African traditional medicine, known for its flavonoid and saponin richness and for its strong antioxidant potential. In the present study, we assessed the effects of Chrysanthellum americanum polyphenolic extract in the psychological stress-induce(...)

Growth and characterization of WSe2 single crystals usingTeCl4 as transport agent
Moussa Bougouma, Bernard Nisol, Thomas Doneux, Boubié Guel, Tiriana Segato, François Reniers, Marie-Paule Delplancke-Ogletree, Jean B. Legma, Claudine Buess-Herman,
The growth of WSe2 single crystals, using TeCl4 as transport agent was performed successfully from slowly cooled polycrystalline powders as precursors. The resulting single crystals were characterized by X-ray diffraction (XRD) and their surfaces examined by scanning electron microscopy (SEM) presented fewer defects than single crystals prepar(...)

LE RÉCIT À L’ÉPREUVE DE L’ARCHÉOLOGIE : LES CHAMPS DE BATAILLE ET REFUGES DU XIX E SIÈCLE EN PAYS TUSIAN (BURKINA FASO)
COULIBALY Pon Jean-Baptiste
Le XIXe siècle marque un tournant décisif dans l'histoire des Tusian. Les guerres et les razzia qui caractérisent cette période ont marqué durablement les consciences. Mais l’histoire sociale et politique de cette période reste encore méconnue car non écrite. Les rares écrits ne sont que des transcriptions des traditions orales encore vivaces(...)

Comparaison et analyse des performances d’un moteur diesel fonctionnant à l’huile de Jatropha préchauffée et au gazole
Y.W. GOUNKAOU, T. DAHO, M. SOUGOTI, A. DIANE, B. NANA, S. K. OUIMINGA, A. BERE
Ce travail a porté sur la comparaison des performances d’un moteur diesel de type LISTER à injection indirecte fonctionnant au gazole et à l’huile pure de jatropha préchauffée (100 °C) ou non. Ce type de moteur est assez répandu en Afrique, plus précisément en milieu rural et sert pour la production agricole et la transformation des produits d(...)

Derivations and Dimentionally Nilpotent Derivations in Lie Algebras
Abdoulaye DEMBEGA , Amidou KONKOBO, MOUSSA OUATTARA
In this paper, we first study derivations in non nilpotent Lie triple algebras. We determine the structure of derivation algebra according to whether it admits an idempotent or a pseudo-idempotent. We study the multiplicative structure of non nil dimensionally nilpotent Lie triple algebras. We show that when n=2 p+1 the adapted basis coincides(...)
