Resistant ultralaminae in soils [PDF]

open access: yesOrganic Geochemistry, 1996
Observation of a chemically resistant organic residue from maize crop soils by transmission electron microscopy reveals the occurrence of thin laminae with 10-50 nm thickness, similar to resistant, highly aliphatic biopolymers found in kerogens and microbes.

Soil resistivity monitoring of an irrigation experiment [PDF]

open access: yes, 2014
Resistivity measurements were used for tracing water transport during a three-year irrigation study. Three different rates of landfill leachate irrigation and one control treatment were applied to two cultivars of short-rotation willow coppice ...

Influence of soil resistivity on stray current in power supply system of urban rail transit

open access: yesJournal of Measurement Science and Instrumentation, 2022
In order to explore the influence of soil resistivity on stray current in power supply system of urban rail transit, we establish an equivalent circuit model of the rail-to-ground structure based on resistance network method first.

Effect of Wetting-Drying Cycles on Mechanical Behaviour and Electrical Resistivity of Unsaturated Subgrade Soil

open access: yesAdvances in Civil Engineering, 2019
Compacted soil is widely used in road and railway subgrade, while alternation of seasons can cause fluctuations in moisture content of soil (i.e., wetting-drying cycles) and influence the performance of soil.

Investigating The Presence Of Groundwater At Landslide Affected Areas Using The 2D Geoelectrical Method (Case Study Of Argopuro Mountain Slope At Suci Village, Jember)

open access: yesJurnal Fisika Flux, 2023
The presence of groundwater and landslides have a close relationship, especially in the context of the influence of groundwater on slope stability. High groundwater levels can cause an increase in hydrostatic pressure on slopes, reduce soil carrying ...

Combination of hydro-geophysical methods for delineation of characteristic structures in subsoil [PDF]

open access: yes, 2012
All terrestrial environmental processes involve the soil including hydrological, geological, meteorological, ecological and anthropological factors. The stress on natural soils increases significantly with agricultural and urban land use as a consequence
