Engineering uses the chloride ion diffusion coefficient as the durability of concrete quality control indicators under the marine environment, due to the chloride ion diffusion coefficient and the electrical resistivity of concrete parameters are reflected in the concrete pore structure, and resistivity testing is convenient, fast advantages, the resistivity alternative chloride ion diffusion c...

[1] The distribution and connectivity of brine pockets in first year sea ice has a determining influence on the bulk properties of the ice and its interaction with the environment. The structure of the brine network depends upon both temperature and salinity, and a full understanding of the temporal evolution of sea ice physical properties requires measurements that are sensitive to the microst...

The U.S. Geological Survey, in cooperation with San Antonio Water System, conducted a geophysical and geological study of the Cibolo Canyon development area, northeast Bexar County, Texas, to characterize hydrostratigraphic features and to map surface and subsurface hydrogeologic features of the Edwards aquifer. Capacitively-coupled (CC) resistivity and frequency-domain electromagnetic (FDEM) p...

Systematic measurements of temperature-dependent magnetization, resistivity, and angle-resolved photoemission spectroscopy (ARPES) at ambient pressure as well as resistivity under pressures up to 5.25 GPa were conducted on single crystals of CrAuTe4. Magnetization data suggest that magnetic moments are aligned antiferromagnetically along the crystallographic c axis below TN=255 K. ARPES measure...

the electrical resistivity of hydrocarbon reservoir rocks is an important parameters in the calculation of water and oil saturation percent in both carbonate and sandstone reservoir rocks.in this regard, most studies have concentrated on the confining  pressure on cementation factor and electrical resistivity in sandstone reservoir rocks. in this study the effect of confining pressure on cement...

This paper reports the correlation between film thickness, nanostructure and DC electrical properties of copper thin films deposited by PVD method on glass substrate. X-ray diffraction (XRD) and atomic force microscopy (AFM) were used for crystallography and morphology investigation, respectively. Resistivity was measured by four point probe instrument, while a Hall effects measurement system w...

A large-scale data set including time-lapse (4D) elastic attributes and electrical resistivity is generated with the purpose of testing algorithms for reservoir modeling, reservoir characterization, production forecasting, and especially joint time-lapse monitoring using seismic as well as electromagnetic data. The Stanford VI reservoir, which was originally created by Castro et al. (2005), is ...

Spin-disorder resistivity of ferromagnetic metals from first principles: The disordered-local-moment approach" (2012). Kirill Belashchenko Publications. Paper 21. The paramagnetic spin-disorder resistivity (SDR) of transition-metal ferromagnets Fe, Co, Ni, ordered transition metal alloys Ni 3 Mn and Fe 3 Si as well as Ni 2 MnX (X = In,Sn,Sb) Heusler alloys is determined from first principles. S...

Electrical impedance tomography (EIT) was used to monitor the movement of a fluorinated hydrocarbon dense nonaqueous phase liquid (DNAPL) through a saturated porous medium within a laboratory column. Impedance measurements were made using a horizontal plane of 12 electrodes positioned at regular intervals around the centre of the column. A 2D inversion algorithm, which incorporated the cylindri...

Characterisation of the heterogeneous naturally fractured reservoirs is an essential and significantly challenging task, especially due to the limited data availability. This paper presents a foundation relationship between P-wave / S-wave velocity and formation resistivity for improved fracture characterisation. Rock matrix and fluid volumetrics are combined with the basic correspondence betwe...
