Holidaymakers concerned about fresh volcanic eruptions causing flight-disrupting ash clouds might be reassured by a study setting out the first reliable estimates of their frequency.While the Universi...
Manifestation of nonlinear elasticity in rock:convincing evidence over large frequency and strain intervals from laboratory studies
nonlinear elasticity in rock large frequency strain intervals laboratory studies

Nonlinear elastic response in rock is established as a robust and representative characteristic rock rather than a curiosity. We show measurements of this behaviour from a variety of experiments on ro...

Frequency patterns of chitinozoans, scolecodonts (polychaete jaws), and conodonts in the upper Llandovery and lower Wenlock of the Paatsalu core, western Estonia, are described. Chitinozoans are repre...
Swelling Pressure of Montmorillonite Layers versus H-O-H Bending Frequency of the Interlayer Water
Bending Frequency Hydration Infrared Spectroscopy Interlayer Force Interlayer Water Montmorillonite Swelling Pressure

The in-depth perturbation of vicinal water by the surfaces of montmorillonite layers was investigated by relating the swelling pressure, Π, of the montmorillonite layers to the H-O-H bending frequency...
Low Frequency Conductivity Dispersion in Clay-Water-Electrolyte Systems
Low Frequency Conductivity Dispersion Clay-Water-Electrolyte Systems

Abstract: The electrical conductivity of a colloid-water-electrolyte system increases with the frequency of the applied alternating electric current. The phenomenon is referred to as conductivity disp...
Low Frequency Dielectric Dispersion of Clay-Water-Electrolyte Systems
Low Frequency Dielectric Dispersion Clay-Water-Electrolyte Systems
2012/2/21
The dielectric properties of saturated kaolinite clay-water-electrolyte systems were determined over the frequency range of 30–105 c/s. Very large dielectric constants are observed at low frequencies....
