The objective of this study was to develop a methodology by which the risk from major accident hazards to the environment can be assessed or quantified. An index method, the Environmental Risk Index (ERI), has been developed based on an existing method, the Environmental Hazard Index (EHI), and the Department of the Environment (DoE) definitions of events that would constitute a major accident ...

A resistive network based anisotropic resistivity reconstruction method is introduced when three sets of internal electrical currents are given. Faraday’s law is discretized using resistive networks for an anisotropic resistivity body such as a muscle or nerve fiber structure of an animal body. The resistivity tensor imaging method of this paper may provide another approach to find the fiber st...

A noncontact technique of measuring the changes in electrical conductivity ~or resistivity! of conducting liquids is reported. The technique is based on a conducting drop that is levitated by the high-temperature electrostatic levitator in a high vacuum. This technique, which utilizes the principle of the asynchronous induction motor, measures the relative changes in torque as a function of tem...

Fly ash resistivity is a single parameter which has got significant impact over sizing and performance of Electrostatic Precipitator (ESP) in coal based thermal power plants. A fly ash resistivity measurement facility has been set up at IIT Delhi with the support of National Energy Technology Laboratory (NETL), USA and USAID-India. The fly ash samples from different power plant are being collec...

Using the Ziman-formulation a model is derived which describes the pressure dependence of the electrical resistivity of d-electron amorphous alloys. It is shown how the volume dependence of the scattering-potential, electron-gas-properties and the Grüneisenparameter determine the P-dependence of a constant and a temperature dependent term in the resistivity. The absolute value of the resistivit...

We studied electrical resistivity and the Hall coe cient of single-crystalline samples of an oxide superconductor Sr2RuO4 under hydrostatic pressures up to 1.2 GPa. The value of Tc decreases by 36 % at 1.2 GPa, while no appreciable change in the resistivity or the Hall coe cient has been observed. At room temperature an unexpected increase of resistivity along the c axis occurs with increasing ...

The electrical resistivity of Co/Ni and Cu/Ni superlattices exhibit resistivity oscillations as a function of superlattice period L, while Ag/Pd does not. Moreover, the resistivity of Co/Ni superlattices shows quantum size effects and a resistivity enhancement with L, as a function of total film thickness d . These results are consistent with a model which assumes d-electron localization in the...

The low-temperature electrical resistivity of corrugated semiconductor films is theoretically considered. Nanoscale corrugation enhances the electron-electron scattering contribution to the resistivity, resulting in a stepwise resistivity development with increasing corrugation amplitude. The enhanced electron scattering is attributed to the curvature-induced potential energy that affects the m...
