Wavelet analysis on pressure stimulated currents emitted by marble samples [PDF]
This paper presents a wavelet based method of analysis of experimentally recorded weak electric signals from marble specimens which have undergone successive abrupt step loadings. Experimental results verify the existence of "memory effects" in

Pressure stimulated currents in rocks and their correlation with mechanical properties [PDF]
The spontaneous electrification of marble samples was studied while they were subjected to uniaxial stress. The Pressure Stimulated Current (PSC) technique was applied to measure the charge released from compressed Dionysos marble samples, while they ...

Abstract The variations in the electric property of loaded rocks are essential in understanding the rock dynamics and fracturing process. Decades of laboratory experiments have revealed different behaviors of stress‐stimulated electric current due to the effects of rock types, loading modes, and detection methods.

Thermal-stimulated pressure and current studies of bound water in lysozyme
The state of bound water in crystalized lysozyme was studied by four techniques: electret thermal depolarization currents, thermal-stimulated pressure, isothermal polization decay, and thermogravimetry. Hydration levels ranged from 0 to 40 mg water/g protein.

The application of load on rock materials stimulates a weak current known as Pressure Stimulated Current (PSC). This study focuses on investigating the damage evolution of granite rocks through the analysis of PSC responses. Uniaxial loading experiments were conducted on granite samples, and the accompanying PSC was measured in real-time.

Purpose: Transcranial direct current stimulation (tDCS) seems to positively modulate the autonomic nervous system in different clinical conditions and healthy subjects; however, its effects on hypertensive (HTN) patients are not completely known. This study aimed to evaluate the effects of a tDCS or SHAM session (20 min) on blood pressure (BP) and ...
