Nitrogen and nitrogen oxides

Medicine, 2003
Abstract Evaporation of liquid nitrogen from the eye or skin may cause cold burns. It may displace oxygen, causing hypoxic asphyxia. Of the nitrogen oxides NO 2 is most toxic. Following exposure, effects in the peripheral airways and alveoli can be expected; clinical symptoms are usually absent during the first hours after exposure.

Nitrogen assimilation and nitrogen control in cyanobacteria

Biochemical Society Transactions, 2005
Nitrogen sources commonly used by cyanobacteria include ammonium, nitrate, nitrite, urea and atmospheric N2, and some cyanobacteria can also assimilate arginine or glutamine. ABC (ATP-binding cassette)-type permeases are involved in the uptake of nitrate/nitrite, urea and most amino acids, whereas secondary transporters take up ammonium and, in some ...

Nitrogen Fixation and Nitrogen Fertilization of Soybeans

Isotopes in Environmental and Health Studies, 1996
Abstract In pot experiments with (15)N labelled soil and mineral (15)N, the influence of Bradyrhizobium (Rhizobium japonicum) inoculation and N fertilization on the symbiotic N(2) fixation and yield of soybeans [Glycine max (L.) Merill., cv. 'Fiskeby V'] was investigated.
