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(...)

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(...)

Electrochemical behaviour of iron (II) at a Nafion-1,10-phenanthroline-modified carbon paste electrode : assessing the correlation between preconcentration potential, surface morphology and impedance measurements
Abdoulkadri Ayouba MAHAMANE, Boubié. GUEL, Paul-Louis FABRE
: The electrochemical behavior of a Nafion-1,10-phenanthroline-modified carbon paste electrode (CMCPE:
Chemically Modified Carbon Paste Electrode) immersed in a supporting electrolyte 0.1 mol.L-1 acetate buffer solution
(pH 4.5) containing iron(II) metal ion has been studied, using cyclic voltammetry, differential-pulse voltammetry and

Fertility limitation and child schooling in Ouagadougou: selective fertility or resource dilution?”,
Moussa Bougma, Thomas K. LeGrand et Jean-François Kobiané
Using original data collected in Ouagadougou, Burkina Faso, this study investigates evidence for the competing theories that fertility reductions increase children's education through either the quantity–quality tradeoff (intentionally choosing smaller families to make greater investments in education and other indicators of child quality) or(...)

APPLICATION DES MÉTHODES STATISTIQUES À L’ÉTUDE HYDROCHIMIQUE DES EAUX D’UN HYDROSYSTÈME TROPICAL : CAS DU BASSIN VERSANT DE LA RIVIÈRE ZIO (TOGO)
Tampo L., Gnazou M., Akpataku V., Bawa L., Djaneye-Boundjou G, Nuto Y, Oueda A. et Guenda W.
Zio River is the only perennial river of Lake Togo basin. It passes through many urban areas including capital Lomé which it receives discharges of all kinds and subjected to several human pressures. This study aims to characterize the physicochemical quality of water from the source to the river mouth, identify pollution sources and highlight(...)

Apkcombiner: Combining multiple android apps to support inter-app analysis
T. BISSYANDE
Android apps are made of components which can leak information between one another using the ICC mechanism. With the growing momentum of Android, a number of research contributions have led to tools for the intra-app analysis of Android apps. Unfortunately, these state-of-the-art approaches, and the associated tools, have long left out the sec(...)

Influence of chemical potential on water transport in a hygroscopic soil
Samuel Ouoba, Fabien Cherblanc, Jean-Claude Bénet, Jean Koulidiati
Concerning the description of mass transport in a porous media, particularly in soil, the question is to know what are the main mechanisms to consider during transport phenomena for a best description of these transports. The answer to this question requires good understanding on thermodynamic law to include in the transport process for a good(...)
