Investigation of groundwater characteristics and its influence on Landslides in Heifangtai Plateau using comprehensive geophysical methods

open access: yesJournal of Groundwater Science and Engineering, 2023
The occurrence of landslides in Heifangtai plateau is primarily caused by the rise in water levels due to irrigation. To accurately understand the distribution of groundwater and its impact on the landslide hazard, a combination of Electrical Resistivity

Development and content validation of a patient-reported endometriosis pain daily diary

open access: yesHealth and Quality of Life Outcomes, 2018
Background Endometriosis is a common gynecological disorder that causes inflammation and pelvic pain. Endometriosis-related pain is best captured with patient-reported outcome (PRO) measures, however, assessment of endometriosis-related pain in clinical ...

Quadrupol ERT [PDF]

open access: yes, 2020
The quadrupole method in geoelectrics was only applied for long offsets in the past. We scaled down the method to profile-style and grid-style short offset applications. The quadrupole approach yields the apparent resistivity in a tensorial form in contrast to the scalar apparent resistivity obtained from classical geoelectrics.

Estimation of the hydraulic parameters of unsaturated samples by electrical resistivity tomography [PDF]

open access: yes, 2012
In situ and laboratory experiments have shown that electrical resistivity tomography (ERT) is an effective tool to image transient phenomena in soils. However, its application in quantifying soil hydraulic parameters has been limited.
