Stress in pacu exposed to ammonia in water
(Sociedade Brasileira de Zootecnia, 2012-07-01)
The present study evaluated stress indicators in pacu exposed to ammonia in water under the following conditions: without NH4Cl (0.00 g/L); with 0.0078 g NH4Cl/L; and with 0.078 g NH4Cl/L (pH 8.3 and 27 ºC). After the salt ...
Electronic properties of liquid ammonia: A sequential molecular dynamics/quantum mechanics approach
(AMER INST PHYSICS, 2008)
The electronic properties of liquid ammonia are investigated by a sequential molecular dynamics/quantum mechanics approach. Quantum mechanics calculations for the liquid phase are based on a reparametrized hybrid ...

Ammonia volatilization losses from surface-applied urea with urease and nitrification inhibitors
(2012-09-01)
Urease inhibitor (UI) and nitrification inhibitor (NI) have the potential to improve N-use efficiency of applied urea and minimize N losses via gaseous emissions of ammonia (NH 3) to the atmosphere and nitrate (NO3-) ...

Urease inhibitor (UI) and nitrification inhibitor (NI) have the potential to improve N-use efficiency of applied urea and minimize N losses via gaseous emissions of ammonia (NH 3) to the atmosphere and nitrate (NO3-) ...
Nitrification and ammonia-oxidizing bacteria shift in response to soil moisture and plant litter quality in arid soils from the Patagonian Monte
(Elsevier Gmbh, 2016-01)
We aimed to evaluate the effects of both plant litter quality, characteristic of sites with different histories of grazing disturbance, and soil water content on nitrification in soils from an arid ecosystem of Patagonia. ...
Surface ammonia-oxidizer abundance during the late summer in the West Antarctic Coastal System
(Frontiers Media, 2022)
Marine ammonia oxidizers that oxidize ammonium to nitrite are abundant in polar waters,
especially during the winter in the deeper mixed-layer of West Antarctic Peninsula (WAP)
waters. However, the activity and abundance ...
