A three-dimensional particle-in-cell simulation in a large system demonstrates that a kink mode significantly contributes to a fast reconnection by providing magnetic dissipation through anomalous resistivity. The anomalous resistivity is generated due to the electron heating in the thin electron current sheet. It is interesting that, although the kink mode broadens the width of the current she...

The Plasma resistivity has been measured in the edge plasma of IR-T1 tokamak. To achive the edge plasma properties ( Te and ne ) using I-V characteristics of movable single langmuir probe. Density and temperature of electron, respectively ne and Te, are measured simultaneously for calculating the radial profile of parallel and vertical resistivity. As temperature of plasma raised, resistivity d...

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...

The interior surfaces of capillaries are lined with a layer (glycocalyx) of macromolecules bound or absorbed to the endothelium. Here, a theoretical model is used to analyze the effects of the glycocalyx on hematocrit and resistance to blood flow in capillaries. The glycocalyx is represented as a porous layer that resists penetration by red blood cells. Axisymmetric red blood cell shapes are as...

In this study, commercial-grade NiCr (80 wt % Ni, 20 wt % Cr) and NiCrSi (55 wt % Ni, 40 wt % Cr, 5 wt % Si) were used as targets and the sputtering method was used to deposit NiCr and NiCrSi thin films on Al₂O₃ and Si substrates at room temperature under different deposition time. X-ray diffraction patterns showed that the NiCr and NiCrSi thin films were amorphous phase, and the field-effect s...

Two important mechanisms affect our ability to estimate solute concentrations quantitatively from the inversion of field-scale electrical resistivity tomography ERT data: 1 the spatially variable physical processes that govern the flow of current as well as the variation of physical properties in space and 2 the overparameterization of inverse models, which requires the imposition of a smoothin...

sn02 nanowires with diameters of 30 — 200 nm have been synthesized by using carbothermalprocess via a thick film of tin dioxide and carbon powder precursor. the nanowires werecharacterized by x-ray power diffraction (xrd), scanning electron microscopy (sem),transmission electron microscopy (tem) and selected area electron diffraction (saed).the gas sensing characteristic of nanowires toward eth...

Studies were done on dogs in vivo to determine the effect of intracardiac blood on the electrocardiogram. By exchange transfusions of packed cells or of Rheomacrodex, hematocrit was raised to over 70% or lowered to 16%. The electrical resistivity of the blood changed accordingly from control values of 150 ohm-cm to over 500 ohm-cm or to as low as 67 ohm-cm. The x-, y-, and zvector leads were pr...

Time-lapse resistivity measurements and groundwater geochemistry were used to study salinity effect on groundwater aquifer at the ex-promontory-land of Carey Island in Malaysia. Resistivity was measured by ABEM Terrameter SAS4000 and ES10-64 electrode selector. Relationship between earth resistivity and total dissolved solids (TDS) was derived, and with resistivity images, used to identify wate...
