Abstract Density-wave fronts in a vibrofluidized wet granular layer undergoing a gas-liquid-like transition are investigated experimentally.The threshold of the instability is governed Cover Sets by the amplitude of the vertical vibrations.Fronts, which are curved into a spiral shape, propagate coherently along the circular rim of the container wit
This article Measuring Rulers presents the results of studying microinclusions of fluids/melts in diamonds from the placers of the Krasnovishersky District (western slope of the Middle/Northern Urals), which make it possible to establish the evolution of diamond-forming media in the subcontinental lithospheric mantle of the eastern margin of the Ea
