Simultaneous Determination of 78 Compounds of Rhodiola rosea Extract by Supercritical CO2-Extraction and HPLC-ESI-MS/MS Spectrometry. [PDF]
Biochem Res Int, 2021 The plant Rhodiola rosea L. of family Crassulaceae was extracted using the supercritical CO2‐extraction method. Several experimental conditions were investigated in the pressure range of 200–500 bar, with the used volume of cosolvent ethanol in the amount of 1% in the liquid phase at a temperature in the range of 31–70°C.

Alleviation of an Arctic Sea Ice Bias in a Coupled Model Through Modifications in the Subgrid-Scale Orographic Parameterization. [PDF]
J Adv Model Earth Syst, 2020 Abstract In climate models, the subgrid‐scale orography (SSO) parameterization imposes a blocked flow drag at low levels that is opposed to the local flow. In IPSL‐CM6A‐LR, an SSO lift force is also applied perpendicular to the local flow to account for the effect of locally blocked air in narrow valleys.

Glacial‐Interglacial Controls on Ocean Circulation and Temperature During the Permo‐Carboniferous
Paleoceanography and Paleoclimatology, Volume 37, Issue 11, November 2022., 2022 Abstract The apex of Earth's penultimate icehouse during the Permo‐Carboniferous coincided with dramatic glacial‐interglacial fluctuations in atmospheric CO2, sea level, and high‐latitude ice. Global transformations in marine fauna also occurred during this interval, including a rise to peak foraminiferal diversity, suggesting that glacial‐interglacial

Journal of Geophysical Research: Atmospheres, Volume 127, Issue 9, 16 May 2022., 2022 Abstract The Tibetan Plateau (TP) is an important forcing in the global climate system. Compared to the extensive studies on the influence of the TP on surrounding climates, the variability of the surface potential vorticity (PV) over the TP (TPSPV) in response to other forcings is seldom discussed.

Diversity and Distributions, Volume 27, Issue 11, Page 2063-2076, November 2021., 2021 Abstract Aims The rapid increase in the number of species that have naturalized beyond their native range is among the most apparent features of the Anthropocene. How alien species will respond to other processes of future global changes is an emerging concern and remains poorly misunderstood.

Metallogeny of the Lyapinsky megablock (Subpolar Urals)
NEWS of the Ural State Mining University, 2021 Purpose of the work: elucidation of the geological structure, manifestations of magmatism, geodynamics and metallogeny of one of the largest segments of the paleocontinental sector of the Lyapin megablock in the Urals. The peculiarity of the metallogenic specialization of the latter for uranium, thorium, rare metals, gold, optical quartz caused both ...

sPlotOpen – An environmentally balanced, open‐access, global dataset of vegetation plots
Global Ecology and Biogeography, Volume 30, Issue 9, Page 1740-1764, September 2021., 2021 Abstract Motivation Assessing biodiversity status and trends in plant communities is critical for understanding, quantifying and predicting the effects of global change on ecosystems. Vegetation plots record the occurrence or abundance of all plant species co‐occurring within delimited local areas.

The Depositional Record, Volume 7, Issue 2, Page 311-332, June 2021., 2021 The Pisanyi Kamen’ section on the Un'ya River, Northern Urals, from the Lower Asselian stratigraphic interval is the central part of a succession of skeletal mounds that are composed of biocementstones. Palaeoecological analysis allows the pioneer stages of the ecological succession, representing the stabilisation and colonisation stages, to be ...
