Balafon et religion au Burkina Faso. du rapport de l’instrument aux pratiques religieuses de la société Goin dans les communes de Banfora et de Niangoloko
FAYAMA Tionyélé, OUEDRAOGO/ROUAMBA Valérie Claudine, HEMA Aimé Désiré
De la sacralisation à l’usage commun quotidien, le balafon a subi des
mutations liées aux processus de transformation et d’évolution de la société Goin
dans toutes ses composantes. Élément de culture banni par les uns et accepté par
les autres. Il s’agit pour nous de montrer les raisons réelles qui ont été à l’origine
de cette universa(...)

Analyse de la dynamique d’occupation des terres dans le bassin versant de la Kompienga au Burkina Faso de 1988 à 2016
SANOU Korotimi, DIPAMA Jean-Marie, KARAMBIRI Bienvenue. Lawankilea Chantal Noumpoa
Au Burkina Faso, la région de l’Est, à l’instar de celles de l’Ouest et du Sud-ouest, est une zone d’accueil pour les migrants en quête de potentialités agroécologiques. Cependant, l’installation de nouveaux arrivants accentue la pression sur les ressources naturelles, déjà sujettes aux vicissitudes climatiques. Le bassin versant de la Kompien(...)

The Effect of Atmospheric Oxygen on the Puffing and Bursting Phenomena during Vegetable Oils Droplets Vaporization Process for Their Use as Biofuel in Diesel Engine
A. S. Zongo, T. Daho, G. Vaitilingom, B. Piriou, J. Valette, C. Caillol, B. G. Segda, P. Higelin, J. Koulidiati.
The past literature on the use of vegetable oils as fuel in diesel engine revealed that utilizing vegetable oil fuels in diesel engines may require property changes in the oil or perhaps, some minor engine modifications or operating changes. This study was conducted to search for the effect of atmospheric oxygen on the puffing and bursting phe(...)

Processing of Canned Mango using Natural Preservatives: Effect on the Physicochemical Characteristics and Hygienic Quality
83. Pingdwindé Marie Judith Samadoulougou-Kafando, Hagrétou Sawadogo-Lingani, Donatien Kaboré, Hyacinthe Kanté-Traoré, Diarra Compaoré-Sérémé and Mamoudou H. DICKO
Optima preservation conditions to produce canned mangoes from three cultivars (Lippens, Kent and Keitt) were determined using lemon juice and lemongrass essential oils as natural preservatives and citric acid. Fresh mango pulp and canned mangoes were analyzed for physicochemical, microbiological and sensorial properties in order to assess the(...)

Intra-Seasonal and Annual Variation of Aerosols and Their Radiative Impact in the Sahelian Zone of Burkina Faso
Bado Nébon, Mamadou Simina Dramé, Saidou Moustapha Sall, Korgo Bruno, Demba Ndao Niang, Kieno P. Florent, Bathiebo Dieudonné Joseph
This paper deals with the characterization of aerosols in the Sahelian zone, particularly in Burkina Faso based on MODIS observations and in situ measurements of the AERONET network on the Ouagadougou site (12.2˚N, 1.4˚W). Thus, a seasonal spatial distribution of aerosols made over the period from 2001 to 2016 gives a very great variability of(...)

Preliminary toxicity and gastroprotective potential of flavonoid-rich fractions of leaves from Opilia celtidifolia (Guill. & Perr.) Endl. ex Walp (Opiliaceae)
Konaté Kiessoun, Dibala I. Crépin, Diao Mamounata, Yomalan Kassi, Alain Souza, Mamoudou H. DICKO
Objective: In Burkina Faso as in other developing countries, the diarrheal diseases constitute a serious problem of public health. To treat diarrhea, most Burkina Faso people living in the rural areas do rely on medicinal plants. To evaluate the traditional use of Opilia celtidifolia, scientific validation is needed. Methods: The collected pla(...)

A Self-Diffusion Mathematical Model to Describe the Toxin Effect on the Zooplankton-Phytoplankton Dynamics
Ouedraogo, Hamidou; Ouedraogo, Wendkouni; Sangaré, Boureima
The main goal of this work is the mathematical formulation, the analysis
and the numerical simulation of a prey-predator model by taking into account the
toxin produced by the phytoplankton species. The mathematical study of the model
leads us to have an idea on the existence of solution, the existence of equilibria and the
stability of th(...)

Temporal variations in transpiration of Vitellaria paradoxa in West African agroforestry parklands
HR Bazié, J Sanou, J Bayala, A Bargués-Tobella, G Zombré, U Ilstedt
Lack of data on water use of key species of drylands constitutes an obstacle to understanding their role in hydrological processes in this environment. To elucidate seasonal variation in water consumption by Vitellaria paradoxa, the dominant species of parklands of the semi-arid areas of West Africa, we've measured its transpiration using heat(...)

Investissement direct étranger et assurance dans les pays en développement : au-delà de l’effet de revenu
Relwendé Sawadogo, Samuel Guérineau, M. Idrissa Ouedraogo
This article studies the impact of FDI inflows on non-life insurance penetration in 76 developing countries over the period 1996-2011. It is based on two well-documented effects in the literature: (i) FDI contributes to income growth per capita, and (ii) higher income per capita increases the development of insurance, especially non-life insur(...)
