Using age‐ratios to investigate the status of two Siberian Phylloscopus species in Europe
Ibis, EarlyView.Distinguishing between vagrancy and regular migration has proved to be challenging as vagrants may, in theory, act as pioneers in the establishment of new migration routes. Because migratory songbirds tend to follow the same orientation and migration route throughout their lives, age assessment can help to distinguish individuals which have already ...

External water exchange of reservoirs of South Ural
IOP Conference Series: Earth and Environmental Science, 2019 Abstract Reservoirs are building worldwide for the rational usage of water resources. Engineers create reservoirs for redistribution of runoff both in seasonal and multi-annual regime. The duration of stay of river water in slow water exchange condition is one of the major factors which influences the transformation of the river water ...

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)?
