We studied resistivity, magnetoresistivity, and Hall resistivity for a few percolating granular NiFe-SiO2 films upon thermal annealing. It was found that both the resistivity and the Hall resistivity decrease by two orders of magnitude upon annealing at 520 °C, accompanied by a crossover from an approximately 2lnT dependence of resistivity to a metallic behavior. On the other hand, transmission...

The Antrim Coast Road stretching from the seaport of Larne in the East of Northern Ireland has a well-deserved reputation for being one of the most spectacular roads in Europe (Day, 2006). However the problematic geology; Jurassic Lias Clay and Triassic Mudstone overlain by Cretaceous Limestone and Tertiary Basalt, and environmental variables result in frequent instances of slope instability ma...

Three industrial solid wastes including red mud, carbide slag, and phosphogypsum combined with ordinary Portland cement were used as curing agents to solidify/stabilize loess polluted by a high concentration of copper ions. The unconfined compressive strength, resistivity, permeability coefficient, ion leaching concentration, pH value, other engineering application evaluation indexes analyzed p...

Electrical resistivity describes how much a certain material resists electrical flow. Every material has an associated resistivity, ρ, which is constant. Conductors, such as copper have a low resistivity, while insulators, such as glass, have a high resistivity. Resistivity is an important property of any electrical object because it directly relates to the resistance, which relates to Ohm’s la...

This work presents a methodology for horizontal soil stratification and device 3D mapping using the discretization of Wenner’s method. The starts from application lateral profiling method in conjunction with to find experimental resistivity curve. Sunde’s algorithm is used construct theoretical By utilizing these curves, it possible apply optimization process parameters: electrical conductivity...

Soil degradation and low productivity are among the major agricultural problems facing farmers of newly reclaimed area in Nile Delta region, Egypt. High content clay silt characterizes soil texture all farms area, while still rely on traditional mole drainage (MD) system to reduce salinity farm soil. We present a comparison innovative geo-resistivity methods evaluate drains affected soils. Geoe...

Measurements of surface resistivity as a function of coverage for oxygen adsorbed on sulfur-predosed Cu(100) films reveal two types of interactions between sulfur and oxygen: S-O repulsion and short-range suppression of the surface resistivity change induced by oxygen adsorption. The repulsive interaction causes oxygen atoms to first occupy adsorption sites far from the sulfur atoms, beyond sec...
