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.

The role of geophysics in enhancing mine planning decision-making in small-scale mining [PDF]

open access: yesRoyal Society Open Science, 2020
Small-scale mining usually operates under high geological uncertainty conditions. This turns mine planning into a complex and sometimes inaccurate task, resulting in low productivity and substantial variability in the quantity and quality of the mineral ...

Temperature dependence of the electrical resistivity and the anisotropic magnetoresistance (AMR) of electrodeposited Ni-Co alloys [PDF]

open access: yes, 2010
The electrical resistivity and the anisotropic magnetoresistance (AMR) was investigated for Ni Co alloys at and below room temperature. The Ni Co alloy layers having a thickness of about 2 micron were prepared by electrodeposition on Si wafers with ...

The structural and dielectric properties of lanthanum substituted strontium based spinel ferrites nano-materials for high frequency device applications

open access: yesJournal of Taibah University for Science, 2023
Lanthanum substitution on spinel Nano particles has a significant repercussion on the several features of materials. Sol–gel (auto-ignition) allowed for the substitution of the rare earth lanthanum ion (La3+) for spinel ferrite with composition SrLaxFe2 ...
