Active electroreception in Gymnotus omarorum is a sensory modality that perceives the changes that nearby objects cause in a self generated electric field. The field is emitted as repetitive stereotyped pulses that stimulate skin electroreceptors. Differently from mormyriformes electric fish, gymnotiformes have an electric organ distributed along a large portion of the body, which fires sequent...

Received Mar 2, 2014 Revised Jul 10, 2014 Accepted Jul 23, 2014 The high level electric field intensity produced by high voltage (HV) equipments inside 500/220 kV substations is harmful for the human (staff) health. Therefore the minimum health and safety requirements regarding the exposure of workers to the risk arising from electric fields produced inside these substations is still considered...

A numerical description is given for the pulsating emission of droplets from an electrified meniscus of an inviscid liquid of infinite electrical conductivity which is injected at a constant flow rate into a region of uniform, continuous or time periodic, electric field. Under a continuous field, the meniscus attains a periodic regime in which bursts of tiny droplets are emitted from its tip. A...

Assembly and directed orientation of anisotropic particles with an external ac electric field in a range from 1 kHz to 2 MHz were studied for asymmetric composite dumbbells incorporating a silica, titania, or titania/silica (titania:silica = 75:25 vol %) sphere. The asymmetric composite dumbbells, which were composed of a polymethylmethacrylate (PMMA)-coated sphere (core-shell part) and a polys...

Electric fields of repetitively pulsed nanosecond discharges have been measured from electric-field induced Raman scattering by hydrogen molecules. Especially the temporal evolution of the electric field spatial distribution was recorded. With a high-speed optical emission intensity analysis, it has been found that most ionization events take place within a very short period during an ionizatio...

Introduction Microwave discharges play an important role in plasma sources for industrial applications like surface modification and thin film deposition. The electric field distribution in the plasma determines the electron density and energy distribution and the homogeneity of the discharge. The typical amplitude of the electric field is of the order of 100 V/cm. Up to now, this low field str...
