Nitrogen Oxides on Mars.

open access: yesThe Astronomical Journal, 1964
Abstract In a series of recent papers, Kiess and collaborators have announced the identification of nitrogen peroxide on Mars and have attempted to interpret a wide range of Martian phenomena in terms of nitrogen oxides. Analyses of observations at a variety of wavelengths in the present paper, and previously by Sinton, Spinrad and Moroz, place a ...

Effect of the temperature of waste cooking oil methyl esters on the value of nitrogen oxides emission from the self-ignition engine [PDF]

open access: yesE3S Web of Conferences, 2020
Combustion of diesel oil and liquid biofuels in self-ignition engines is related to the emission of harmful gases to the atmosphere (i.e. nitrogen, carbon or sulfur oxides).

RESEARCH AND ASSESSMENT OF THE ENVIRONMENTAL SECURITY OF BAKERY ENTERPRISES

open access: yesHarčova Nauka ì Tehnologìâ, 2020
The paper considers how to decrease the concentration of nitrogen oxides in gas emissions of bakery enterprises. Nitrogen oxides (NOx) formed in the course of burning natural gas  are responsible for more than 90% of an enterprise’s hazard category.
