Convergent flow in a two-layer system and mountain building [PDF]
With the purpose of modelling the process of mountain building, we investigate the evolution of the ridge produced by the convergent motion of a system consisting of two layers of liquids that differ in density and viscosity to simulate the crust and the

Reidite Formation From Zircon Subjected to 20, 40, and 60 GPa Shock Experiments
Structure disordering as a result of shock pressure: In zircon shocked from 20 to 60 GPa, the shock‐induced structural disorder increases with increasing shock pressure (gray area). Shock disorder of zircon is an integral part of its transformation to reidite: Reidite occurs after amorphous material.

On the ecology of species belonging to the genus Mesocyclops Sars (Crustacea, Copepoda) dwelling in the water-bodies of the Urals and Pri-Ural territory. [Translation from: Zoologicheskie Zhurnal 44(1) 127-130, 1965. ] [PDF]
In the waterbodies of central Russia, the Urals and western Siberia four species of Crustacea, related to the genus Mesocyclops, are widely distributed: M. (s.str.) leuckarti (Claus), M. (Thermocyclops) oithonoides Sars, [M.](Th.) crassus (Fisch.) and M.

Tracing holotype trajectories: Mapping the movement of the most valuable herbarium specimens
Global efforts to protect biodiversity depend on fair access to key plant specimens. This study examines the distribution of 119,361 holotypes—unique herbarium specimens used to formally describe new plant species. By linking collection and storage data, we found that holotypes are increasingly held closer to their places of origin, particularly in ...

Threshold Currents of Vacuum Arcs With Tungsten and Copper Cathodes
ABSTRACT This paper presents the results of an experimental study aimed at determining the threshold current for triggering a vacuum arc discharge, the probability of arc ignition and the average arc operation time depending on the current for tungsten and copper electrodes.

Abstract In the summer of 1919, W. T. Goode, the Manchester Guardian’s special correspondent in Russia and the Baltic, was arrested in the Estonian capital Tallinn and briefly detained aboard a British warship. Goode's detention caused a furore, leading to accusations of kidnap, heated commentary in the press and questions in parliament.
