Lichtenberg discovered dust figure phenomena of electrical discharges in 1777. His discovery came to the notice of many scientists because it was considered that the figures should show the motion of the electric fluid. Photographic Lichtenberg figures were obtained in the middle of the nineteenth century. Both of these figures, usually called "Lichtenberg figures", have been utilized in the st...

The natural electrical phenomena fascinated humans since antiquity. The electrical discharges produced by the torpedo fish were highly appreciated among ancient physicians as Hippocrates, Scribonius Largus and Galen and were prescribed for headache, gout and prolapsed anus. In the medieval period, torpedo's electrical properties were attributed to occult powers, while Renaissance physicians' an...

High voltage arc discharge is a method to pasteurize liquid foods by applying rapid discharge voltages through an electrode gap below the surface of aqueous suspensions of microorganisms. Inactivation of microorganisms and enzymes contained in food products by electrical discharges began in the 1920s with the electropure process for milk. This process consisted of passing an electrical current ...

Production of active species is studied in N2 and in N2-O2 afterglows of electrical discharges at low and atmospheric gas pressures. They are produced in microwave discharges in a large range of gas pressures from a few Torr to 100 Torr and in corona discharges at atmospheric gas pressure. The active species in N2 afterglows are the N-atoms which are in the range of a few percents in the afterg...

Objective(s):Protective effects of diuretics, particularly of hydrochlorothiazide (HCT), for the development of seizure attacksepilepsy have been described in vivo. However, itsthe mechanism of action of HCT is unknownneeds to be elucidated. Materials and Methods: Extracellular field potentials were recorded from the CA1- and CA3-subfields of the hippocampus of rats. Epileptiform discharges wer...

Although lightning has not been observed in Titan's atmosphere, the presence of methane rain in the troposphere suggests the possibility of electrical activity in the form of corona and/or lightning discharges. Here we examine the chemical effects of these electrical processes on a Titan simulated atmosphere composed of CH4 in N2 at various mixing ratios. Corona discharges were simulated in two...
