Working with epitaxial films of Fe, we succeeded in independent control of different scattering processes in the anomalous Hall effect. The result clearly exposed the fundamental flaws of the conventional scaling rhoAH=f(rho(xx)) between the anomalous Hall resistivity and longitudinal resistivity. A new scaling rhoAH=f(rho(xx0),rho(xx)) that also involves the residual resistivity has been estab...

The present work envisages the possible geometry of a contaminated plume of groundwater near hospital facilities by combining GIS (Geographic Information System) and geophysical methods. The rock underlying the soil and thin sedimentary cover of the study area is moderately fractured quartzite, which makes aquifers vulnerable to pollution. The GIS methodology is used to calculate the area that ...

the pellet-type sno2 sensor was synthesized by the solid state method and the effects of additives such as nano zno (1-12 mol %) and nano in2o3 (1-10 mol %) on the co gas sensitivity of sensor were investigated. the optimum sintering temperature was chosen 800°c because of the porosity content of the samples. the phase analysis and microstructure of the samples were studied by x-ray diffraction...

It is one of the most puzzling problems in astrophysics to understand the anomalous resistivity in collisionless magnetic reconnection that is believed extensively to be responsible for the energy release in various eruptive phenomena. The magnetic null point in the reconnect current sheet, acting as a scattering center, can lead to chaotic motions of particles in the current sheet, which is on...

The existing knowledge regarding seawater intrusion and particularly upconing, in which both problems are linked to pumping, entirely relies on theoretical assumptions. Therefore, in this paper, an attempt is made to capture the effects of pumping on seawater intrusion and upconing using 2D resistivity measurement. For this work, two positions, one perpendicular and the other parallel to the se...

geological conditions of tabriz, a growing city in nw-iran, are strongly influenced by north tabriz fault (ntf). north tabriz fault is a major seismogenic fault in nw-iran. so, for a correct seismic microzonation, shear wave velocity (vs) structure in different part of city should be determined. but urban conditions, such as ambient noise due to cultural activity, restrict the general applicati...
