Electroreceptive fish detect nearby objects by processing the information contained in the pattern of electric currents through the skin. The distribution of local transepidermal voltage or current density on the sensory surface of the fish's skin is the electric image of the surrounding environment. This article reports a model study of the quantitative effect of the conductance of the interna...

background: the use of electric current during application of etch-and-rinse adhesive systems has been recently introduced to decrease microleakage. this study investigated the effects of an electric field produced by an experimental device for the application of a two-step etch-and-rinse adhesive on moist dentin surface. methods: sixty freshly extracted human premolars were used for this study...

the computer simulation program of a practical scale reverse electrodialysis process has been developed based on the program for saline water electrodialysis. the program is applied to compute the performance of an industrial-scale reverse electrodialysis stack (effective membrane area s = 1 m × 1 m = 1 m2, cell pair number n = 300 pairs). the stack operatingconditions are optimized. seawater a...

In this work, a tracer study on pore initiation in anodic alumina in oxalic acid was performed. Effects of some experimental parameters such as applied electrical potential, electrolyte composition and heat pretreatment were evaluated. Electrochemical and morphological experiments were performed using potentiostatic anodizing and scanning electron microscopy (SEM) techniques, respectively. Effe...

For all study participants, birth and death addresses were visited and a map of the wires and transformers of the electric power distribution was drawn. Homes were categorized as having "high-current configurations" (HCC), "low-current configurations" (LCC), or "very low current configurations" (VLCC), according to their proximity to high current distribution lines. Table 2 shows the distributi...

This paper proposes a methodology for practical siting and sizing of Hybrid energy systems (HESs) consist of: wind turbine (WT), photovoltaic (PV) and combined heat and power (CHP) units. In this method, the interaction of Plug-in Electric Vehicles (PIEVs) in the electric distribution system is considered. Electric Vehicle are seen to have some negative impacts on electric distribution system p...

Rational development of transcranial current stimulation (tCS) requires solving the 'forward problem': the computation of the electric field distribution in the head resulting from the application of scalp currents. Derivation of forward models has represented a major effort in brain stimulation research, with model complexity ranging from spherical shells to individualized head models based on...
