Target-Size-Dependent Application of Electrostatic Techniques for Pest Management in Greenhouses

open access: yesAgronomy, 2022
Two new electrostatic devices were developed to manage greenhouse insect pests. One was an electrostatic insect catcher (EIC) to trap small flying pests, and the other was an arc-discharge zapper (ADZ) to kill larger insects emerging from soil beds.

Tripolar electric field Structure in guide field magnetic reconnection [PDF]

open access: yesAnnales Geophysicae, 2018
It has been shown that the guide field substantially modifies the structure of the reconnection layer. For instance, the Hall magnetic and electric fields are distorted in guide field reconnection compared to reconnection without guide fields (i.e ...

Magnetic control of the pair creation in spatially localized supercritical fields [PDF]

open access: yes, 2012
We examine the impact of a perpendicular magnetic field on the creation mechanism of electron-positron pairs in a supercritical static electric field, where both fields are localized along the direction of the electric field.

Electric fields and electrical insulation [PDF]

open access: yesIEEE Transactions on Dielectrics and Electrical Insulation, 2002
The adoption of a field-theoretical approach to problems arising in the framework of electrical insulation is discussed with reference to six main topics, which have been addressed over the last 30 years. These include uniform field electrodes, Green's differential equation, electrode surface roughness, induced charge, electrostatic probes, and partial

Three-axis electrical induction sensor of electric field strength in form of three mutually perpendicular disks [PDF]

open access: yesОмский научный вестник, 2020
Measuring the parameters of electric fields affecting technical and biological objects is impossible without the use of electric field strength sensors. Accurate measurement and control of electric field strength levels is challenging.
