this paper describes the application of approximate methods to invert airborne magnetic data as well as helicopter-borne frequency domain electromagnetic data in order to retrieve a joint model of magnetic susceptibility and electrical resistivity. the study area located in semnan province of iran consists of an arc-shaped porphyry andesite covered by sedimentary units which may have potential ...

Chemiresistor sensors made from carbon black – polyisobutylene composite, perform based on the change of the resistivity of the composite when they swell in the analytes. Two models are necessary to describe the mechanism of carbon-polymer chemiresistors theoretically: the conductivity model and the thermodynamic model. In this work, the conductivity model was studied. Sixty-four chemiresistors...

This article reviews our recent experimental studies of domain wall (DW) resistivity in epitaxial transition metal ferromagnetic thin film microstructures with stripe domains. The results are presented and analysed in the context of models of DW scattering and conventional magnetoresistance (MR) effects in ferromagnetic metals. Microstructures of progressively higher magnetic anisotropy and thu...

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...

We have implemented a magnetotelluric observation in the Nanling-Xuancheng Ore Concentration Area within Middle-lower Yangtze River Metallogenic Belts. The data with 0.001–1000 s period was collected at 843 distinct sites, and all components are handled 3-D inversion of observed dataset. present first detailed resistivity structure beneath overlying sediment strata Area. shallow parts inverted ...
