Diversity and distribution of bats (Mammalia Chiroptera) in Burkina Faso
Napoko Malika KANGOYÉ, Adama OUÉDA, Laurent GRANJON, Adjima THIOMBIANO, Wendengoudi GUENDA and Jakob FAHR
Herein we review available information on the bat fauna of Burkina Faso, synthesizing data
on a considerable number of museum specimens collected in the country between 1964 and
2010. We aim to give an exhaustive review of the locally occurring taxa and their distribution
overlaid on different phytogeographic areas. To achieve this objectiv(...)

Highlighting of a local non-equilibrium thermodynamics during the transfer of trichlorethylene (TCE) in the superficial layers of arid soils
Samuel Ouoba, Bruno Cousin, David Y. Toguyeni, Salifou K. Ouiminga, Fabien Cherblanc, Jean Koulidiati and Jean-Claude Bénet
In this paper, we analyse and model the mass transfer of trichloroethylene in the surface layer of soil. Our study essentially focuses on arid soils taking into account the phase change liquid–vapour. We have then examined the validity of the assumption of local equilibrium by comparing the values of instantaneous pressure of the trichloroethy(...)

Do floristic composition, plant species abundance and vegetation structure in Sudanian wetlands vary according to conservation status?
Soungalo Soulama1, 2*, Blandine M.I. Nacoulma2, Patrice Savadogo3, Yvonne Bachmann4, Adjima Thiombiano2
In Sahel, wetlands are particularly endangered hence practical knowledge for their sustainable management is needed. The aim of this study was to compare plant community structure between protected and unprotected wetland bank stands in eastern Burkina Faso. Phytosociological and dendrometrical parameters were carrying out in adult trees, seed(...)

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(...)

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 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(...)

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(...)
