Toward a Pattern-based e-learning software design approach
Tonguim Ferdinand Guinko, Laurence Capus, Hatem Ben Sta
Enthusiasm for educational software sometimes hides some real problems, which have some negative repercussions on the efficiency and the quality of learning undertaken by learners. Among those problems are the poor analysis, the poor design and the ignorance of the pedagogical theoretical aspects in the design process. This work proposes an e-(...)

SELECTION OF PHENOTYPIC INTERESTS FOR THE CULTIVATION OF THE PLANT Cleome gynandra L. IN THE VEGETABLE GARDENS IN BURKINA FASO
Zakaria KIEBR, Pauline BATIONO/KANDO, Nerbéwendé SAWADOGO, Mahamadou SAWADOGO, Jean-Didier ZONGO
Present study was aimed to understand the scientific basis of the farmer’s nomenclature of the local varieties of Cleome gynandra L. and to identify the characters of interests that can be used for the varietal improvement of the species. A survey was carried out in five cities of Burkina Faso with 56 producers of C. gynandra with the help of(...)

Electrocatalytic activity carbon-supported metallophthalocyanine catalysts toward oxygen reduction reaction in alkaline solution
Seydou Hebié, Mabinty Bayo-Bangoura, Karifa Bayo, Karine Servat, Claudia Morais,Teko W. Napporn, K. Boniface Kokoh
Carbon-supported metallophthalocyanine catalysts,
composed of a transition central metal M (M = Co, Mn, Ni,
Fe) in the phthalocyanine ring, were synthesized in this work.
As cathodic reaction in a fuel cell, the oxygen reduction reaction
(ORR) was investigated in alkaline medium with linear
scanning voltammetry at the surface of these ele(...)

Nonlinear optical properties of poly(methyl methacrylate) thin films doped with Bixa Orellana dye
S. Zongo, A.P. Kerasidou, B.T. Sone, A. Diallo, P. Mthunzi, K. Iliopoulos,M. Nkosi, M. Maaza, B. Sahraoui,
Natural dyes with highly delocalized π-electron systems are considered as promising organic materials for nonlinear optical applications. Among these dyes, Bixa Orellana dye with extended π-electron delocalization is one of the most attractive dyes. Bixa Orellana dye-doped Poly(methyl methacrylate) (PMMA) thin films were prepared through spin(...)

Linear and nonlinear optical absorption characterization of natural laccaic acid dye
S. Zongo, S. M. Dhlamini, A. P. Kerasidou, P. Beukes, B. Sahraoui, M. Maaza,
We report on the optical performances of laccaic acid dye in solution at different concentrations and dye–poly(methyl methacrylate) composite thin films. The linear spectral characteristics including optical constants, i.e. refractive index (n) and extinction coefficient (k), were carried out in a comprehensive way through absorbance, fluoresc(...)

Optimization of Aqueous Extraction of Anthocyanins from Hibiscus sabdariffa L. Calyces for Food Application
DIESSANA Arthur, Charles Parkouda, Mady Cissé, Bréhima Diawara, and Mamoudou H. DICKO
Aqueous extracts of Hibiscus sabdariffa calyces are worldwide used for the production of several products such as polyphenolic-antioxidant containing beverages. However, optima conditions for extraction of polyphenolics such as anthocyanins from this plant species were unknown. For this, the influence of particle size and calyx/water ratio on(...)

Good measures for nonlinear Neumann anisotropic problems with variable exponent
I. Konaté, S. Ouaro
We study in this paper a nonlinear anisotropic problem with homogeneous Neumann boundary condition and Radon diffuse measure data which does not charge the sets of zero p(⋅)-capacity. We first prove, by using the techniques of monotone operators in Banach spaces, the existence of weak solutions and by approximation methods, the existence and u(...)

Optimization of Hydrocarbons Biodegradation by Bacterial Strains Isolated from Wastewaters in Ouagadougou, Burkina Faso : Case Study of Diesel and Used Lubricating Oils
Sawadogo Adama, Otoidobiga C.Hamonie, Kaboré Aminata, Sawadogo B. Joseph, Traoré S. Alfred, Dianou Dayéri
Diesel oil and lubricants are hydrocarbons commonly used in the world. Contamination of environment by used
lubricating and diesel oil is rapidly increasing due to global increase in the usage of petroleum products,
particularly in developing countries. This has been shown to have harmful effects on the environment and
human beings. Thus, t(...)

Verbal autopsy of stillbirths and neonatal deaths in a rural area of Burkina Faso.
K. NAGALO
Introduction: In developing countries, many neonatal deaths still occur at home and the causes of these deaths are not ascertained. Objective: To identify the causes of stillbirths and neonatal deaths that occur at home and the factors that have contributed to these deaths. Materials and Method: We have used the method of verbal autopsy to inv(...)

«Ahmadou Kourouma : un écrivain au carrefour de l’oralité et de la créativité moderne»
Alain Joseph Sissao, Benjamin Sou
Les romanciers africains comme Ahmadou Kourouma écrivent en français mais essaient d’adapter cette langue à leur contexte d’énonciation. C’est dans cette perspective que Jean-Pierre Makouta M’Boukou note : « les négro-africains écrivent en français, en anglais, en espagnol ou en portugais, déclare-t-on toujours. C’est que ces Africains ne font(...)
