Abstract A mathematical model is developed to determine the steady-state electric current flow through in non-homogeneous isotropic conductor whose shape has a three-dimensional hollow body. The equations of Maxwell's theory solid body are used formulate corresponding boundary value problem. determination steady motion charges based on concept electrical conductance. derivation upper and lower ...

in this research, the spatial distribution of electrical conductivity and ph of springs, ghanats and the base flow concentration places on the streams of central and south-west and central parts of the hamedan-bahar plain were evaluated. using different geostatistical methods such as kriging, minimum curvature, inverse distance, natural neighbor, local polynomial and radial basis functions, 108...

Stellate cells from entorhinal cortex (EC) layer II express both a transient Na(+) current (I(Na)) and a low-threshold persistent Na(+) current (I(NaP)) that helps to generate intrinsic theta-like oscillatory activity. We have used single-channel patch-clamp recording to investigate the Na(+) channels responsible for I(NaP) in EC stellate cells. Macropatch (more than six channels) recordings sh...

The effects of intercellular coupling conductance on the activity of two electrically coupled isolated rabbit sinoatrial nodal cells were investigated. A computer-controlled version of the "coupling clamp" technique was used in which isolated sinoatrial nodal cells, not physically in contact with each other, were electrically coupled at various values of ohmic coupling conductance, mimicking th...

Low-frequency skin conductance is used within several clinical applications and is mainly sensitive to sweating and the moisture content of the stratum corneum, but also how electrodes introduce changes in the electrical properties. Four electrode gels were investigated with regard to sorption characteristics and electrical properties. Skin conductance time series were collected from 18 test su...

This work presents the role of graphene in improving performance a porous GaN-based UV photodetector. The photodetector, with mean pore diameter 35 nm, possessed higher sensitivity, about 95% better compared to that as-received (non-porous) In addition, it exhibits lower magnitude leakage current at dark ambient, 70.9 μA, photodetector 13.7 mA. However, is also highly resistive nature due corre...

We study electrical modulation of transport properties silicene nanoconstrictions with different geometrical structures. investigate the effects position and width central scattering region on conductance increasing Fermi energy. It is found that significantly depends nanoconstriction. Interestingly, symmetrical structure constriction can induce a resonance effect increase systemʼs conductance....
