This study provides forensic search teams with systematic geophysical monitoring data over simulated clandestine graves for comparison to active cases. Simulated ‘wrapped’ and ‘naked’ burials were created. Multi-geophysical surveys were collected over a three-year monitoring period. Bulk ground resistivity, Electrical Resistivity Imaging, multi-frequency Ground Penetrating Radar and grave ‘soil...

Electrical resistivity evolution during precipitation in Al-Sc alloys is modeled using cluster dynamics. This mesoscopic modeling has already been shown to correctly predict the time evolution of the precipitate size distribution. In this work, we show that it leads too to resistivity predictions in quantitative agreement with experimental data. We only assume that all clusters contribute to th...

We have prepared Gd,-IPrXBa,Cu,O,-, phase spread alloy thin films with well-defined variations in the concentration of Pr across a single substrate. Their Pr concentrations were independently determined from electrical resistivity and Auger electron spectroscopy measurements. The results from both methods are in good agreement with each other. Using this technique several high-temperature super...

The probability tomography approach developed for the scalar resistivity method is here extended to the 2D tensorial apparent resistivity acquisition mode. The rotational invariant derived from the trace of the apparent resistivity tensor is considered, since it gives on the datum plane anomalies confined above the buried objects. Firstly, a departure function is introduced as the difference be...

The formation resistivity factor evaluation of brine-filled reservoir rock is an essential part of electrical resistivity log interpretation in petroleum exploration. Empirical relations such as Archie’s law are widely employed to model the relationship between the formation resistivity factor and porosity. Historically, the Archie cementation exponent has been obtained from experimental labora...

This paper discusses modeling of non-uniform substrate resistivity for substrate resistance extraction. Though substrate resistivity of each substrate layer is frequently assumed to be uniform, doping profile of each substrate layer is not uniform. We present the extraction error of substrate resistance under uniform resistivity assumption. The resistivity models we suggest enable accurate resi...

This is a general review of anomalous resistivity with emphasis on its applicability in space and more specifically on ionospheric plasmas. It is addressed to the general ionospheric community rather than the specialist. Therefore a substantial amount of rigor has been sacrificed in favor of simplified physical pictures. However, several prescriptions are presented, on the basis of which one ca...

There is low resistivity contrast between reservoir zone and host formation in geothermal fields, especially in areas where the technique of water injection is being carried out. Therefore, in low contrast area, permittivity can be one of the important reservoir indicators besides resistivity. In this study, one EM tomography method of reconstructing the resistivity and permittivity from electr...

Single frequency bioelectrical impedance analysis is an inexpensive, quick and painless means of estimating body composition. However, current approaches to estimating body composition from segment resistivity have some drawbacks. The purpose of this study was to overcome these limitations by developing a better model of the relationship between resistivity and body composition. A three-compart...

Materials and methods The questionnaire used for the practicing medics was the effort-reward-imbalance (ERI) model of Siegrist et al. The questionnaire used for the students survey was the effort-reward-imbalance (ERI) model for school and student settings. The ERI scores on a 5 point Likert scale. In total, N = 716 medical students completed the questionnaire (65.4% female, 34.6% male). 61% of...
