Counterpoints of modern phraseology. To the anniversary of Prof. V.M. Mokienko

The paper is timed to coincide with the 80th anniversary of the birth of Valery M. Mokienko, Doctor of Letters, Professor of Slavic Philology, Philology Department, St Petersburg State University, Honorary Chairman of the Phraseological Commission of the International Committee of Slavists. The paper reviews focal areas of the scholar’s research, lists his academic interests, the main of those being phraseology and phraseography. V.M. Mokienko proposed to detect dynamic interactions of contradictory properties of the phraseological system, to reveal the mechanism of phrase formation involving broad genetic and typological parallels to determine the nature of a phraseological unit. The method of structural and semantic modeling based on a detailed comparison of dialectal, Slavic and non-Slavic European idiomacy is the basis of modern theoretical and practical studies of the scientist’s followers. The trilogy of dictionaries edited by V.M. Mokienko distinguishes precise certification of units, references to synonymous turns, which makes it easier for the reader to navigate in the huge source material, outlines the parameters of the phraseological space close to the certified expression, and makes it possible to show the wealth of images of folk speech conveying the same semantics. © 2020 Bierich A., Lomakina O.V., Nikolaeva E.K., Seliverstova E.I., Stepanova L.I

Field Emission from As-Grown and Ion-Beam-Sharpened Diamond Particles Deposited on Silicon Tips

Ion-beam bombardment/milling was used for sharpening of diamond particles deposited on ends of silicon tips. Radii curvature of diamond coating down to about 20 nm have been formed in such a way. Field emission experiments with sharpened diamond coated emitters have shown that the ion beam treatment effects a considerable shift of current-voltage characteristics of in the lower voltage region

The foraminiferal zonal scale of the Devonian–Carboniferous boundary beds in Russia and Western Kazakhstan and its correlation with ammonoid and conodont scales

This paper reviews the foraminiferal biostratigraphy of the Devonian–Carboniferous (D–C) boundary beds in Russia and Western Kazakhstan. The regional records of the zonal successions of Russia are summarised from sections and boreholes of the Volga-Urals Subregion of the East European Platform (Syzran no. 401 Borehole, Melekesskaya no.1 Borehole); Timan-Pechora Province of the East European Platform (Kamenka Section); South Urals (Sikaza, Zigan, Ryauzyak and Dzerzhinka sections); Middle Urals (Pershino Section); and West Siberia, Vagai-Ishim Basin (Borehole no. 1 Kurgan-Uspenskaya), and the zonal successions of Western Kazakhstan are summarised from the Mugodzhary Mountains. Three foraminiferal biozones can be defined in the interval comprising the latest Devonian and earliest Carboniferous: Quasiendothyra kobeitusana Zone, the Tournayellina pseudobeata – remnant Quasiendothyra Zone, and the Earlandia minima Zone. The D–C boundary interval is situated within the Tournayellina pseudobeata–remnant Quasiendothyra Zone. A correlation with the ammonoid and conodont zonations is proposed, which is useful for correlating deep-water and shallow-water successions

Arctic Ostracode Database 2010

Paleo-sea-ice history in the Arctic Ocean was reconstructed using the sea-ice dwelling ostracode Acetabulastoma arcticum from late Quaternary sediments from the Mendeleyev, Lomonosov, and Gakkel Ridges, the Morris Jesup Rise and the Yermak Plateau. Results suggest intermittently high levels of perennial sea ice in the central Arctic Ocean during Marine Isotope Stage (MIS) 3 (25-45 ka), minimal sea ice during the last deglacial (16-11 ka) and early Holocene thermal maximum (11-5 ka) and increasing sea ice during the mid-to-late Holocene (5-0 ka). Sediment core records from the Iceland and Rockall Plateaus show that perennial sea ice existed in these regions only during glacial intervals MIS 2, 4, and 6. These results show that sea ice exhibits complex temporal and spatial variability during different climatic regimes and that the development of modern perennial sea ice may be a relatively recent phenomenon. The new 2010 database is a significant expansion and improvement over the 1995 database in several respects. It includes data from 680 samples (compared to 403 samples in 1995) from a total of 54 sources (oceanographic cruises, sampling programs, publications) described in OstArcSamples. The database has updated taxonomy given in OstArcSpecies. In addition to the census data, the OstArcCensus file also contains water temperatures for each site obtained from World Ocean Atlas 2001 (Stephens et al. 2002), and, for many samples, a second temperature value taken at the time of the cruise or obtained from early oceanographic sources. The sources for these temperatures are given in OstArcTemp. A few typographical errors from the 1995 database have been corrected and updated longitude and latitudes are provided for older samples collected in the 1930s through 1960s using new archives and the International Bathymetric Chart of the Arctic Ocean to better locate samples (IBCAO, Jakobsson et al. 2008). In addition to the surface sample ostracode data, this database provides late Quaternary sediment core records of the sea-ice dwelling species Acetabulastoma arcticum (OstArcSeaIce). The late Quaternary record of A. arcticum represents an application of the surface sample database to reconstruct paleo-sea-ice history of the central Arctic Ocean and adjacent seas during glacial, deglacial, interglacial (Holocene), and interstadial (Marine Isotope Stage 3) (Cronin et al. 2010)
