Proximity Effects of Lateral Conductivity Variations on Geomagnetically Induced Electric Fields

Effects of interactions between stations on the calculation of geomagnetically induced currents in an electric power transmission system

“Geomagnetically induced currents” (GIC) in ground-based technological networks are a manifestation of space weather. GIC are a potential source of problems to the systems and therefore important in practice. GIC in a power system (or in principle in any other discretely-earthed system) can be calculated conveniently by using matrix equations presented earlier. Since temporal variations associa...

Effects of Statically Electric Fields on Freezing Parameters and Microstructures of Button Mushrooms (Agaricus bisporus)

Background and Objectives: Freezing under statically electric fields is one of the novel freezing methods to improve the quality of frozen products by controlling the nucleation process. The objective of this study was to investigate effects of freezing under electrostatic fields on the freezing parameters and microstructures of frozen button mushrooms. Materials and Methods: Mushroom samples w...

Geomagnetically Induced Currents as Ground Effects of Space Weather

Dielectrophoretic effect of nonuniform electric fields on the protoplast cell

In recent years, dielectrophoresis based microfluidics systems have been used to manipulate colloids, inert particles, and biological microparticles, such as red blood cells, white blood cells, platelets, cancer cells, bacteria, yeast, micro‌organisms, proteins, DNA, etc. In the current study the governing electric potential equations have been solved in the presence of cell for the purpose of ...
