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

Health 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 ...

3-D GPR visualization technique integrated with electric resistivity tomography for characterizing near-surface fractures and cavities in limestone

Journal of Taibah University for Science, 2022
Near-surface geophysical techniques, (i.e. ground-penetrating radar (GPR) and electric resistivity tomography (ERT)), continue to enable great possibilities for 3-D visualization of fractures and cavities. An integrated survey, including GPR and ERT, was

Quadrupol ERT [PDF]

, 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.
