The knowledge of the electric current density distribution generated by an electrode array is very useful in electrotherapy for tumor treatment. We propose an innovative mathematical approach that takes into account planar solid tumor elliptic geometry, electrical differences between it and its...

The electric conductivity of a nonionic water-in-oil microemulsion has been measured in the presence of small amounts of carrier electrolyte. Two distinct regimes can be distinguished: the conductivity increases linearly for small nanodroplet concentration, while it decreases above a critical...

The effects of the radial electric field E/sub r/ on the bootstrap current in ATF-type configurations are studied with the Drift Kinetic Equation Solver (DKES). It is found that there is a range of E/sub r/ values over which the bootstrap current does not depend on E/sub r/. The effects of E/sub...

A three-dimensional model for thermal analysis has been developed to gain a better understanding of thermal behavior in a vanadium flow battery (VFB). The model is based on a comprehensive description of mass, momentum, charge and energy transport and conservation, combining with a global...

Lithium ion (Li-ion) battery, consisting of multiple electrochemical cells, is a complex system whose high electrochemical and thermal stability is often critical to the well-being and functional capabilities of electric devices. Considering any change in the specifications may significantly...

Contrary to more advanced countries, Russia’s district heating hardly embraces radical innovations. Moving forward with breakthrough solutions, even if they have proven their effectiveness at leading European companies and are supported by federal and regional authorities, encounters...

Electricity and heat generation are key contributors to global emissions of greenhouse gases (GHG). In this paper, specific attention is paid to renewable energy technologies (RETs) for electricity and heat generation and reviews current understanding and estimates of life cycle GHG emissions...

The present article assesses the residual biomass availability and its energy potential in the Party of General Pueyrredón, a region located southeast of the province of Buenos Aires, Argentina. These were considered herbaceous and vegetable residues derived from the agricultural activity...

This paper discusses structure, impact, costs, and efficiency of renewable energy supply in the eight largest advanced economies (the G-7 plus Spain), with focus on Germany. Renewables production costs are compared to benefits, defined as reductions in net carbon emissions; technological...
