Electrical resistivity measurements to predict abrasion resistance of rock aggregates

The Abrasion and Brittleness Coefficients of Tabriz’s Metro Aggregates

Introduction Urban development and rapid extension of cities have been accompanied by a considerable growth in mechanized tunneling. The abrasivity of rock and even soil is a factor with considerable influence on the wear of tools. Soil abrasion and the resulting tool wear has a major impact on machine operation, utilization, and tunneling costs and time. One of the problematic aspects of work...

Electrical Resistivity and Contact Resistance of Electrically Conductive Silicones

Cable accessories for mediumand high voltage applications contain field grading and field zoning parts or layers. These parts often consist of electrically conductive silicone elastomers. The electrical conductivity is achieved by using selected and long-term tested carbon blacks. Conductive layers and parts are used to provide safety against exposure, inner shielding and an electrical contact ...

Electrical impedance measurements predict cellular transformation.

Cellular transformation is the first step in cancer development. Two features of cellular transformation are proliferation in reduced serum and loss of contact inhibition. Electronic Cell-Substrate Impedance Sensing (ECIS) measurements have been used to measure cellular proliferation, cytotoxicity, apoptosis, and attachment. We have used impedance measurements to distinguish normal cells from c...
