The synthesis of metallic nanoparticles is an active area of academic, application research as well and nanotechnology. Different chemical and physical procedures that are currently used for synthesis of metallic nanoparticles present many problems. These problems include generation of hazardous by-products, use of toxic solvents, and high ene(...)

Tomato chlorotic mottle Guyane virus: a novel tomato-infecting bipartite begomovirus from French Guiana
Jean-Michel Lett, Alexandre De Bruyn, Murielle Hoareau, Alassane Ouattara, Sohini Claverie, Anne Dalmon, Damien Laplace, Pierre Lefeuvre, Bruno Hostachy
This is the first description of the complete genome sequence of a new bipartite begomovirus isolated from tomato (Solanum lycopersicum) in French Guiana, for which we propose the tentative name ‘‘tomato chlorotic mottle Guyane virus’’ (ToCMoGFV). DNA-A and -B nucleotide sequences of ToCMoGFV are only distantly related to known New World begom(...)

Effets de la date de semis et du régime hydrique sur la réponse agromorphologique de deux variétés de niébé (KN1 ET KVX 61-1) au Burkina Faso
Adama Pascal KIHINDO , Romeo Hugues BAZIE, Razacswendé Fanta OUEDRAOGO, Pépin Patrice SOME, Gérard ZOMBRE, and Koffi TOZO
Cowpea (Vigna unguiculata L.Walp.) is a basic food product which is cultivated in the savannas of west Africa. Its cultivation is confronted to biotic and abiotic constraints. The abiotic constraints are primarily of climatic types (recorded rainfall, temperature). The bad spatiotemporal distribution of recorded rainfall as well as the high te(...)

Phenolic compounds, antioxidant and antibacterial activities of three Ericaceae from Algeria
M. KIENDREBEOGO
Herbs of the Ericaceae family are commonly found in Algeria and used in traditional medicine as antiseptic, diuretic, astringent, depurative, and to treat scalds and wounds. The methanolic extracts of three species, Arbutus unedo L.(A. unedo, leaves), Erica arborea L.(E. arborea, flowered aerial parts), and Erica multiflora L.(E. multiflora, f(...)

Assessment of benthic molluscs diversity and distribution in urban reservoirs (Ouagadougou, Burkina Faso)
Idrissa OUEDRAOGO, Adama OUEDA, Djidama SIRIMA, Ilassa OUEDRAOGO, Wendengoudi GUENDA and Gustave B. KABRE
The urban reservoirs n° 2 and n°3 of Ouagadougou, located in the middle of the city are subject to multiple anthropogenic pressures which threaten the diversity of benthic macroinvertebrates community group like molluscs. This study was initiated to assess the diversity and distribution of benthic molluscs in these reservoirs. Molluscs samples(...)

Nonlinear optical properties of natural laccaic acid dye studied using Z-scan technique
S. Zongo, K. Sanusi, J. Britton, P. Mthunzi, T. Nyokong, M. Maaza, B. Sahraoui
We have investigated the nonlinear optical properties, including the optical limiting behaviour for five different concentrations of laccaic acid dye in solution and a thin film obtained through doping in poly (methyl methacrylate) (PMMA) polymer. The experiments were performed by using single beam Z-scan technique at 532 nm with 10 ns, 10 Hz(...)

Analyse des facteurs d’évolution de l’utilisation des terres dans le bassin versant de la Kompienga (Burkina Faso)
KABORE Oumar, OUEDRAOGO Lucien, OUEDRAOGO Blaise, DIPAMA Jean Marie et DA Evariste Dapola
Les changements dans l‟utilisation des terres affectent les écosystèmes ainsi que les conditions de vie de l‟homme. Ils sont déterminés par des facteurs socioéconomiques dont la connaissance permet de mieux appréhender certaines modifications de notre environnement. Le présent article a pour objet de contribuer à mieux connaitre ces
facteurs(...)

On the capacitance of crystalline silicon solar cells in steady state
FABE IDRISSA, BARRO MOUSTAPHA SANE , BERNARD ZOUMA
In this work, an analytical approach is presented for modeling the capacitance of crystalline silicon solar cells. Based on a one-dimensional modeling of the cell, the excess minority carrier density, the photovoltage, and the capacitance are calculated. The motivation of this work are two-fold: to show base doping density and illumination eff(...)

Bottom-up adoption of software product lines: a generic and extensible approach
T. BISSYANDE
Abstract Although Software Product Lines are recurrently praised as an efficient paradigm for systematic reuse, practical adoption remains challenging. For bottom-up Software Product Line adoption, where a set of artefact variants already exists, practitioners lack end-to-end support for chaining (1) feature identification,(2) feature location(...)

Energy-free Security in Wireless Sensor Networks
Adel Elgaber, Julien Bernard, Yacouba Ouattara
Wireless sensor networks are often deployed in open and uncontrolled environments that make them more vulnerable
to security attacks. Cryptographic algorithms can be used to protect the data collected by the sensors against an intruder. The cost in terms of energy to provide enough security can be quite large as these algorithms may be very c(...)
