The article gives the electrical conductivity of whole and shredded plant tissue. An experimental study was made of the dependence of the resistivity value and the volume occupied by the pulp on the pressing time and specific pressures on the pulp while taking into account the amount of pressed juice. The electrical resistance (R) of whole and crushed plant tissue was experimentally studied, which, when processing the results, was recalculated to the specific electrical resistance (ρ) of the tissue. The specific pressure (P) on the tissue was determined using a reference manometer, and the deformation (ΔH) of the sample was measured with a dial indicator.

The article considers the problems of forecasting the performance of cutting tools equipped with replaceable ceramic cutting bits. It is proposed to forecast the operability of ceramic tools on the ground of dependence between its performance characteristics and the microstructural parameters of the tool material. It is proposed to determine the parameters of ceramic bits microstructure by a nondestructive testing methods based on measuring the specific electrical resistance of ceramic materials. As a result of the study we have undertaken, a relationship was detected between the performance and specific electrical resistance of ceramic cutting tools.

The paper describes methods developed to determine specific electrical conductivity and relative magnetic permeability of cylindrical steel items and nano-coatings deposited on them by sputtering. Research enables development of a new method for determination of thickness of vacuum deposited nano- coating that is based on application of skin effect.
