Research ArticleOpen accessAll words, across the recordLyapunov Function for a Dengue Transmission Model where two Species of Mosquitoes are Present: Global StabilityI Ming Tang, Rattiya Sungchasit, Puntani PongsumpunIn this study, we are interested in the newly observed endemic due to the ZIKA virus. In the absence of a full knowledge of the dynamics of the infection due to this virus, we consider a model of the closely related dengue virus when there are two species of mosquitoes, A. aegypti and A. albopictus mosquitoes who are both capable … …American Journal of Applied Sciences, Vol. 14, Issue 10 · 25 Oct 2017 · 8,274 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordOptimal Planning and Design of an Environmentally Friendly Hybrid Energy System for Rural Electrification in IraqAli Saleh Aziz, Sara Ahmed KhudhierCurrent power systems create environmental effects because of the using of fossil fuels, specially coal, since CO2 is released to the atmosphere. Contrary to conventional energy sources, renewable energy sources produce a clean energy which is in general free of pollution, environmentally sustainable and technologically efficient. There is an increased interest in solar energy that can generate electricity with no … …American Journal of Applied Sciences, Vol. 14, Issue 1 · 26 Jan 2017 · 7,803 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordNitrifying, Denitrifying and Heterotrophic Biomass Present in Moving Bed-ReactorAndreliza Carolina Del Grossi Oliveira, Camila Zoe Correa, Kátia Valéria Marques Cardoso Prates, Deize Dias LopesThis study was carried out to evaluate the main bacterial communities related to the removal of nitrogen in a moving bed-reactor treating landfill leachate, relating the physico-chemical parameters with the existence of these organisms in the mixed liquor (non-attached microorganisms) and Support Material (SM). The system was operated in two phases: Phase I (without effluent recirculation) and II (with recirculation, … …American Journal of Environmental Sciences, Vol. 13, Issue 1 · 25 Jan 2017 · 7,628 accessesView PDFCite
