Electromagnetic induction heating as a driver of volcanic activity on massive rocky planets

open access: yes, 2020
Aims. We investigate possible driving mechanisms of volcanic activity on rocky super-Earths with masses exceeding 3-4 Mearth. Due to high gravity and pressures in the mantles of these planets, melting in deep mantle layers can be suppressed, even if the ...

The Electrical Conductivity as an Index of Air Pollution in the Atmosphere [PDF]

open access: yes, 2011
Air is never perfectly clean. Many natural sources of air pollution have always existed. Ash from volcanic eruptions, salt particles from breaking waves, pollen and spores released by plants, smoke from forest and brushfires, and windblown dust are all examples of natural air pollution.

Electrical conductivity of plasmas of DB white dwarf atmospheres

open access: yes, 2012
The static electrical conductivity of non-ideal, dense, partially ionized helium plasma was calculated over a wide range of plasma parameters: temperatures $1\cdot 10^{4}\textrm{K} \lesssim T \lesssim 1\cdot 10^{5}\textrm{K}$ and mass density $1 \times ...

Assessment of soybean (Glycine max) vigour by the seed leachate conductivity assay

open access: yesActa Societatis Botanicorum Poloniae, 2015
Conductivity of seed leachates is inversely correlated with germination and growth of soybean, Glycine max (L.) Merr., at low temperatures. It is concluded that the seed leachate conductivity assay can be employed to assess soybean seed vigour.
