Ecosystem carbon balance of temperate forests differing in elevation and nitrogen availability [PDF]

, 2014
This PhD thesis addressed the carbon (C) balance of temperate deciduous forests across natural gradients of temperature and nitrogen (N) availability, the major drivers of net primary production (NPP) and the soil C balance.

The nitrogen oxide synthase effect in endothelium reaction and change in peripheral perfusion under THz radiation of nitrogen oxide occurrence exposure

Russian Open Medical Journal, 2013
There is new information about the mechanism of THz radiation of molecular emission and absorption spectrum (MEAS) of 150.176-150.664 GHz nitrogen oxide occurrence exposure. Organized experiments let us establish the fact that a normalizing effect of THz

NOx Prediction Based on Cylinder Pressure Measurement for Engine Emission Monitoring [PDF]

, 2011
Meeting European NOx emission standards is one of the biggest challenges facing automotive industries. The available technologies to measure NOx emission are dependent on measurement of different NOx species.

Nitrapyrin addition mitigates nitrous oxide emissions and raises nitrogen use efficiency in plastic-film-mulched drip-fertigated cotton field.

PLoS ONE, 2017
Nitrification inhibitors (NIs) have been used extensively to reduce nitrogen losses and increase crop nitrogen nutrition. However, information is still scant regarding the influence of NIs on nitrogen transformation, nitrous oxide (N2O) emission and ...

Application of Bayesian statistics to estimate nitrous oxide emission factors of three nitrogen fertilisers on UK grasslands [PDF]

, 2019
Trapezoidal integration by linear interpolation of data points is by far the most commonly used method of cumulative flux calculations of nitrous oxide (N2O) in studies that use flux chambers; however, this method is incapable of providing accurate ...

Global-scale modeling of nitrogen balances at the soil surface [PDF]

, 2005
This paper provides global terrestrial surface balances of nitrogen (N) at a resolution of 0.5 by 0.5 degree for the years 1961, 1995 and 2050 as simulated by the model WaterGAP-N.

N2O reduction in soils [PDF]

, 2008
N2O is a known greenhouse gas that increased by 16% over the last 200 years. The main sources are native and agricultural soils where predominantly soil bacteria perform nitrification and denitrification with N2O as side and intermediate product ...

Emissions of nitrous acid (HONO), nitric oxide (NO), and nitrous oxide (N2O) from horse dung

Agricultural and Food Science, 2016
Horse dung contains considerable amounts of nitrogen which is partly lost during the storage period. Leaching of nitrogen from the dung can be prevented with constructions but also gaseous N-emissions occur.

Catalytic purification of nitrogen oxides for complex industrial flue gas

能源环境保护
Nitrogen oxides, as one of the main atmospheric pollutants, cause potential risks to human health and the atmospheric environment. In recent years, nitrogen oxide emissions from power plants have been reduced, and controlling nitrogen oxide pollution in ...
