The analysis of the quantum Hall response of a small system of interacting ultracold bosonic atoms through the variation of its Hall resistivity against the applied gauge magnetic field provides a powerful method to unmask its strongly correlated states in a quite exhaustive way. Within a fixed range of values of the magnetic field in the lowest Landau-level regime, where the resistivity displa...

Managed aquifer recharge (MAR) is an efficient way to remove organic matter from raw water and, at the same time, reduce temperature variation. Two MAR sites were constructed by Karlskrona municipality on Johannishus Esker in Sweden. One of these sites, Vång, was monitored for electrical conductivity and electrical resistivity (using electrical resistivity tomography ERT) during a 9-week tracer...

In the United States, nursing programs are commonly evaluated by their graduates success on the National Council Licensure Examination for Registered Nurses (NCLEX-RN c ©). The purpose of this paper is to describe a change in NCLEX-RN c © success rates following the addition of standardized exams throughout our program’s curriculum, and to compare these exam scores between graduates who pass NC...

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...

We report the dependence of magnetoresistance effect on resistivity (ρ) in Co/ZnO films deposited by magnetron sputtering at different sputtering pressures with different ZnO contents. The magnitude of the resistivity reflects different carrier transport regimes ranging from metallic to hopping behaviors. Large room-temperature magnetoresistance greater than 8% is obtained in the resistivity ra...

[email protected] ( Abstract We demonstrated the efficiency of a solution-processed planar heterojunction organometallic trihalide perovskite solar cell can be increased to 17.5% through doping the hole transporting layer for reducing the resistivity. Doped Poly(triaryl amine) (PTAA) by 2,3,5,6-Tetrafluoro7,7,8,8-Tetracyanoquinodimethane (F4-TCNQ) reduc...

MnxNi0.5 _ xZn0.5Fe2O4, (x = 0.05, 0.1, 0.2, 0.3, 0.4) ferrites synthesized by the citrate precursor method are investigated in the present work. Compositional variation of AC resistivity is studied and values up to 10 times greater than those for samples prepared by the conventional ceramic method are observed. It is found that resistivity decreases with increase in Mn concentration except for...

AIMS Reentrant activity in the heart is often correlated with heterogeneity in both the intracellular structure and the interstitial structure surrounding cells; however, the combined effect of cardiac microstructure and interstitial resistivity in regions of source-load mismatch is largely unknown. The aim of this study was to investigate how microstructural variations in cell arrangement and ...

Parker instability leads to the formation of tangential discontinuities in a magnetic field and subsequent magnetic reconnection due to a numerical and/or an explicit resistivity. In this paper we investigate the role of the uniform, localized and numerical resistivity on the diffusion of magnetic field lines during the growth phase of Parker instability modes. We propose a new method to quanti...

Electrical resistivity (ER) is a main parameter in the melting processes of glasses. However, its measurement is difficult at high temperatures. In this study the electrical resistivity of different cordierite glass samples in the molten state was measured in the temperature range of 1100˚C to 1550 ˚C using the two-wire method. It was attempted to decrease the electrical resistivity of the glas...
