Nitrogen removal in marine environments: recent findings and future research challenges [PDF]

open access: yes, 2005
Respiratory reduction of nitrate (denitrification) is recognized as the most important process converting biologically available (fixed) nitrogen to N2. In current N cycle models, a major proportion of global marine denitrification (50–70%) is assumed to

Influence of carbon dioxide content in the biogas to nitrogen oxides emissions [PDF]

open access: yesHemijska Industrija, 2010
Fuels derived from biomass are an alternative solution for the fossil fuel shortage. Usually this kind of fuels is called low calorific value fuels, due to the large proportion of inert components in their composition.
