An evaluation of weld metal nitrogen retention and properties in 316NL austenitic stainless steel [PDF]

open access: yes, 2011
A series of tests were conducted using varying levels of nitrogen and helium in a conventional argon shielding gas when welding 316LN austenitic stainless steel. The outcome was that a 15 per cent nitrogen addition to the argon shielding gas had the most

The role of nitrogen uptake on the competition ability of three vineyard Saccharomyces cerevisiae strains [PDF]

open access: yes, 2017
Three vineyard strains of Saccharomyces cerevisiae, P301.4, P304.4 and P254.12, were assayed in comparison with a commercial industrial strain, QA23. The aim was to understand if nitrogen availability could influence strain competition ability during ...

A secular increase in continental crust nitrogen during the Precambrian [PDF]

open access: yes, 2017
Recent work indicates the presence of substantial geologic nitrogen reservoirs in the mantle and continental crust. Importantly, this geologic nitrogen has exchanged between the atmosphere and the solid Earth over time. Changes in atmospheric nitrogen (i.
