Understanding Chemical Equilibrium: The Role of Gas Phases and Mixing Contributions in the Minimum of Free Energy Plots
(American Chemical Society, 2017-03)
The use of free energy plots to understand the concept of thermodynamic equilibrium has been shown to be of great pedagogical value in materials science. Although chemical equilibrium is also amenable to this kind of ...
Single-phase current-source-boost inverter for renewable energy sources
(2011-09-21)
This paper presents a new methodology for the operation and control of a single-phase current-source (CS) Boost Inverter, considering that the conventional CS boost inverter has a right-half-plane (RHP) zero in its ...

Comparison of equatorial GPS-TEC observations over an African station and an American station during the minimum and ascending phases of solar cycle 24
(European Geosciences Union (EGU), 2013-11)
GPS-TEC data were observed at the same local time at two equatorial stations on both longitudes: Lagos (6.52° N, 3.4° E, 3.04° S magnetic latitude), Nigeria; and Pucallpa (8.38° S, 74.57° W, 4.25° N magnetic latitude), ...
Estudo da influência da quantidade de lodo na produção de biogás em reator UASB tratando esgoto doméstico
(Universidade Federal de Minas GeraisUFMG, 2015-10-29)
Treatment of domestic raw sewage through anaerobic leads to the formation of biogas, which can be harnessed as energy. However, the stations find it difficult to understand the behaviour of the production, so as to estimate ...

Seasonal trend analysis of minimum air temperature in La Plata river basin
(Springer Wien, 2021-04)
Regional economies that depend predominantly on agriculture and livestock are heavily affected by changes in air temperature, one such case are the activities in La Plata river basin (LPB). Some studies suggest that ...
