The electrical resistivity of cytoplasm

open access: yesBiophysical Journal, 1976
The apparent cytoplasmic resistivity of two different giant cells has been measured using an extension of a previously developed single microelectrode technique. Each cell is penetrated by a metal microelectrode whose complex impedance is measured as a function of frequency between 500 kHz and 5.7 MHz.

Estimation of the hydraulic parameters of unsaturated samples by electrical resistivity tomography [PDF]

open access: yes, 2012
In situ and laboratory experiments have shown that electrical resistivity tomography (ERT) is an effective tool to image transient phenomena in soils. However, its application in quantifying soil hydraulic parameters has been limited.

Monitoring the bio-self-healing performance of cement mortar incubated within soil and water using electrical resistivity [PDF]

open access: yes, 2023
In research on self-healing concrete, the restorative performance can be evaluated by a wide range of techniques. However, most of these techniques can be challenging to apply to concrete samples embedded in soil without causing a significant disturbance

The Measurement of Electrical Resistance [PDF]

open access: yesNature, 1894
Abstract In the present state of electrical science, the determination of the electric resistance of a conductor may be considered as the cardinal operation in electricity, in the same sense that the determination of weight is the cardinal operation in chemistry.

Experimental Study on Electrical Resistivity of Cement-Stabilized Lead-Contaminated Soils

open access: yesAdvances in Civil Engineering, 2018
Geotechnical applications based on soil resistivity measurement are becoming more popular in recent years. In order to explore the potential application of the electrical resistivity method in stabilization/solidification of contaminated soils, two kinds

Permeability evaluation for artificial single rock fracture according to geometric aperture variation using electrical resistivity

open access: yesJournal of Rock Mechanics and Geotechnical Engineering, 2021
A convenient approach was proposed by which to evaluate and monitor the permeability of a rock fracture by verifying the quantitative correlation between the electrical resistivity and permeability at laboratory scale.
