The paper presents the results of factor analysis multi-electrode geoelectric data measured in area Surány aquifer. 9-variable dataset on first profile was examined by using 2, 3, 4 and 5 factors. calculations show that Factor 1 carries effects IP (Induced Polarization), while 2 shows effect apparent resistivity (Rho) with greatest weight. In weight current (In) is largest. Based all this, it c...

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...

introduction: occurrence of landslides depends on several factors such as the composition and structure of earth materials, rainfall level, temperature, groundwater regime and cover crops. landslides are a main natural hazard in iran, because of its special geological conditions and its mountainous active tectonic regime. linear civil structures, such as roads, highways and railways, face serio...

Abstract We have investigated the Vanadium- (V) substituted Ni–Zn–Co ferrites where samples are prepared using solid-state reaction technique. The impact of V 5+ substitution on structural, magnetic, dielectric and electrical properties has been studied. XRD analysis confirms formation a single-phase cubic spinel structure. lattice constants calculated both theoretically experimentally along wi...

The well Sarai Sidhu-01 is located on Punjab Platform, Central Indus Basin, Pakistan. Punjab Platform is the eastern part of Central Indus Basin, and tectonically it is the stable portion of Indus Basin, which was least affected during Tertiary Himalayan orogeny. This study attempts to decipher reservoir potential for hydrocarbon exploration. It aims to delineate a subsurface hydrocarbon bearin...

Recently proposed potential has been used to calculate the contribution of a point defect to the electrical resistivity of simple and non-simple metals including d and f-shell metals. The parameter of the potential has been determined using zero pressure condition while the exchange and correlation effect due to Taylor is incorporated. Our present findings for Al, Pb, Cu, Ag and Au are excellen...

An integrated surface geophysical pilot study at the Texas A&M University Brazos River Hydrologic Field Research Site (BRHFRS), College Station, Texas, was done to determine the effectiveness of methods for defining the hydrostratigraphic framework and hydrogeologic properties for a ground-water availability model. Time-domain electromagnetic (TDEM) soundings and direct-current (2D–DC) resistiv...

Abstract Cementation factor has a crucial role in evaluating volumetric reserves for heterogeneous clastic reservoir. Bioturbation is prominent source of heterogeneity existing hydrocarbon-bearing formation across the world. The effect bioturbation on petrophysical properties not been comprehensively understood yet, especially its cementation estimation. precise description such beneficial deve...
