Electric field strength and epithelization in the newt (Notophthalmus viridescens)

The Journal of Experimental Zoology, 1996
There is convincing evidence that endogenous electric fields are necessary for normal wound epithelization, but it is unclear whether normal epithelization rates can be accelerated increasing normal field strengths. Although we confirmed that normal lateral fields are required for normal Notophthalmus viridescens epithelization rates, significant ...

Optical measurements of electric field strength in nonuniform fields

[1991] Proceedings of the 3rd International Conference on Properties and Applications of Dielectric Materials, 2002
Describes optical measurements of the field-strength map in a liquid dielectric using the Kerr effect. Since electric lines of force are curved in a nonuniform field, the field strength can be measured on a plane which divides the center axis of two sphere electrodes into two equal parts and is perpendicular to the axis. On this plane, all of the field

Controlling flow direction in nanochannels by electric field strength

Physical Review E, 2015
Molecular dynamics simulations are conducted to study the flow behavior of CsF solutions in nanochannels under external electric fields E. It is found that the channel surface energy greatly affects the flow behavior. In channels of high surface energy, water molecules, on average, move in the same direction as that of the electric field regardless of ...

The mechanical transduction of physiological strength electric fields

Bioelectromagnetics, 2008
AbstractIn this article it is proposed that electric fields of physiological strength (∼100 V/m) are transduced by the mechanical torque they exert on glycoproteins. The resulting mechanical signal is then transmitted to the cytoskeleton and propagated throughout the cell interior.

New Standard of Electric Field Strength

IEEE Transactions on Instrumentation and Measurement, 1970
A new technique is presented for establishing a standard of electric field strength using a highly conducting sphere. An analysis is made to determine the current on the sphere as a function of the electric field strength of an incident plane wave. A method of measuring that current using electronic circuitry and an optical indicator within the sphere ...

Determination of the local electric field strength near electric breakdown

2010 17th IEEE International Symposium on the Physical and Failure Analysis of Integrated Circuits, 2010
For a detailed understanding of near electric breakdown a semiconductor device is analyzed by complementary Optical Beam Induced Current and energy-dispersive Photon Emission Microscopy. The potential and limit as well as the physical background of both techniques for the determination of the local electric field strength are discussed in detail.

Distribution fitting for long term electric field strength measurements

2017 40th International Conference on Telecommunications and Signal Processing (TSP), 2017
As a result of the enormous increase in usage of wireless systems; electromagnetic radiation (EMR) sources in residential areas as well as the exposed EMR levels has increased significantly. Therefore this study aims to determine the exposed E levels and characterize the electromagnetic environment on the basis of long term (24 hours) E measurements ...

Strength of the electric field in apertureless near-field optical microscopy

Journal of Applied Physics, 2001
Enhancement γ of the electrical field at the end of a tip relative to the incident field in a focused radiation beam is calculated by the finite-element time-domain (FETD) method. First, the reliability of the FETD method is established by calculating the electric field on simple structures like thin cylinders, spheres, and ellipsoids, and comparing ...

Dependence of ultrasonic attenuation in semi-conductors on electric field strength

Czechoslovak Journal of Physics, 1965
The dependence of the ultrasonic attenuation, or amplification, in semi-conductors on the electric field strength is derived. It is shown that the ultrasonic amplification does not increase linearly with the field, but, after reaching a maximum, it again decreases.

Electric-field strength in a cascade argon arc

Journal of Engineering Physics and Thermophysics, 2000
An experimental investigation of the electric-field strength along the length of a cascade argon at a pressure lower than atmospheric pressure has been performed. The influence of different processes on the formation of the voltage-current and E-I characteristics of the arc was considered.
