Characterising sand and gravel deposits using electrical resistivity tomography (ERT) : case histories from England and Wales [PDF]

, 2012
Electrical Resistivity Tomography (ERT) is a rapidly developing geophysical imaging technique that is now widely used to visualise subsurface geological structure, groundwater and lithological variations.

Ischemia–Reperfusion Injury: Molecular Mechanisms and Therapeutic Interventions

MedComm, Volume 7, Issue 7, July 2026.
Multiorgan ischemia–reperfusion injury begins with ischemia‐induced ATP depletion and ionic imbalance, followed by reperfusion‐triggered mitochondrial ROS/RNS bursts, regulated cell death, and DAMP release. Sterile inflammation converges on endothelial–immune–coagulation crosstalk, where NETs drive immunothrombosis, no‐reflow, and remote organ injury ...

Dissolution-enlarged fractures imaging using electrical resistivity tomography (ERT)

, 2017
In recent years the electrical imaging techniques have been largely applied to geotechnical and environmental investigations. These techniques have proven to be the best geophysical methods for site investigations in karst terrain, particularly when the ...

Considerations on the Electrode-Spacing-to-Electrode-Diameter Ratio in Electrical Resistivity Tomography (ERT): An Operational Approach

IEEE Transactions on Instrumentation and Measurement
To develop small-scale, shallow, and high-resolution electrical resistivity surveys (e.g., for archaeological or agricultural purposes) the available literature highlights few requirements in terms of distance between two adjacent electrodes or electrode’s length embedded in the soil.

Permafrost Distribution in the Canadian Rockies: Key Variables Influencing Patch‐Scale Variability

Permafrost and Periglacial Processes, Volume 37, Issue 3, Page 372-390, July/September 2026.
ABSTRACT The spatial distribution of permafrost in mountainous regions is influenced by various factors such as topography, climate, vegetation, and substrate. Despite the existence of comprehensive permafrost maps at national and global levels, they fail to accurately represent the patch‐scale (e.g., < 25 m) permafrost distribution in characteristic ...

Spatial Variability of Permafrost and Active Layer Thickness in a Forested Hillslope of the Taiga Shield

Permafrost and Periglacial Processes, Volume 37, Issue 3, Page 306-322, July/September 2026.
ABSTRACT Under continued climate warming, understanding present‐day permafrost distribution and the controls on ground thaw are critical for predicting permafrost thaw trajectories and associated implications. This study presents a high‐resolution investigation of permafrost extent and active layer thickness (ALT) across a coniferous forested hillslope
