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(...)

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(...)

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

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(...)

On constacyclic codes over Z_p^m,
Mohammed Elhassani Charkani, Joël Kabore
Let p be a prime number, m = 2 a positive integer, and t a unit of R = Z_p^m, the ring of integers modulo p^m. Let
N = p^kn with gcd(p, n) = 1. In this work, we give a simple and short proof that the quotient ring R[X]I
is a principal ring. This allow us to study (1 + tp)-constacyclic codes of arbitrary length and give a characterization of(...)
