Pele's hairs and exotic multiply twinned graphite closed-shell microcrystals in meteoritic dust of Chelyabinsk superbolide [PDF]
arXiv, 2019 When a space body enters Earth's atmosphere, its surface is exposed to high pressure and temperatures. The airflow tears off small droplets from the meteoroid forming a cloud of meteorite dust. Can new materials be synthesized in these unique conditions (high temperature, pressure, gaseous atmosphere, catalysts)?

A New Dynamic Model to Predict the Effects of Governmental Decisions on the Progress of the CoViD-19 Epidemic [PDF]
arXiv, 2020 We have established a novel mathematical model that considers various aspects of the spreading of the virus, including, the transmission based on being in the latent period, environment to human transmission, governmental decisions, and control measures.

Meteoritics &Planetary Science, EarlyView.Abstract Combining electron backscatter diffraction (EBSD) with X‐ray computed tomography (XCT) offers a comprehensive approach to investigate shock deformation and rock texture in meteorites, yet such integration remains uncommon. In this study, we demonstrate the synergistic potential of XCT and EBSD in revealing deformation metrics, thereby ...

Unexpected pathway for intercontinental movement into the Nearctic revealed by phylogenetic analyses
Zoologica Scripta, EarlyView.Abstract Much of North America's freshwater biodiversity is derived from Palearctic lineages. Isopods of the Holarctic family Asellidae are among the most widespread and diverse freshwater crustaceans, but Nearctic species are poorly studied. We examined the evolutionary history of the family, utilizing Sanger sequencing of mitochondrial and nuclear ...

Geochemical features of groundwater in the South Urals
Известия высших учебных заведений: Геология и разведка, 2016 This paper gives an analysis and generalization of the data on groundwater chemical and gas composition, located deep in the largest tectonic structures of the Urals. The distribution of groundwaters by the degree of mineralization and composition is subjected to the normal vertical hydrogeochemical zonation.
