Changer in the texture orientation of electrolytic nickel by cold air plasma

open access: yesЛитьë и металлургия, 2020
The effects of cold air plasma influence on the change in the microstructure, stress state and texture of the cathode nickel brand H-1 were studied. By the method of target metallography it has been established that the microstructure does not change ...

Race to the Pole: Matthew Henson, Arctic Explorer

open access: yesAmerican Studies in Scandinavia, 2022
In his memoir, A Negro Explorer at the North Pole (1912), Matthew Henson describes the toll of his and Peary’s race to the Pole. This record of the 1908-09 Arctic expedition complicates established understandings of the “Dash to the Pole” and his own ...
