Effects of nitrogen gas supersatu- ration on growth and survival in juvenile Atlantic cod ( Gadus morhua L. ) [J]. Aquaculture,2008,283( 1 -4) : 175 -179.Gunnarsli, K.S., Toften, H., Mortensen, A., 2008a. Effects of nitrogen gas supersaturation on growth and survival in juvenile...
There are seven oxides of nitrogen that may be found in the ambient air. Nitrous oxide (N2O) is a greenhouse gas with significant anthropogenic sources contributing to its worldwide abundance (~ 0.3 ppm). However, nitric oxide (NO) and nitrogen dioxide (NO2) are the two principal nitrogen ...

Energy of second ionisation 2856 kJ.mol -1 Energy of third ionisation 4578 kJ.mol -1 Discovered by Rutherford in 1772 Nitrogen Nitrogen is a common normally colourless, odourless, tasteless and mostly diatomic non-metal gas. It has five electrons in its outer shell, so it is trivalent in...
We investigate the effects of NO annealing and forming gas(FG) annealing on the electrical properties of a SiO_2/SiC interface by low-temperature conductance measurements.With nitrogen passivation,the density of interface states(D_(IT)) is significantly reduced in the entire energy range,and the ...
Soil nitrogen (N) deficiencies can affect the photosynthetic N-use efficiency (PNUE), mesophyll conductance (gm), and leaf N allocation. However, lack of information about how these physiological characteristics in N-fixing trees could be affected by soi
Table 2 Effect of nitrogen supplementation on the total chlorophyll, carotenoids and gas exchange parameters in Triticum aestivum L subjected to salinity stress. Data is mean (±SE) of three replicates. Values followed by different letters are significantly different at P < 0.05 Full size table ...
the diffusion combustion occurring in diesel engines is the primary source of nitrogen oxide (NOx) and particulate matter (PM) emissions. NOx and PM are generated in different regimes of diffusion combustion. NOx is produced in regions of local stoichiometric equivalence in which the combustion tempe...
Anaerobic ammonium oxidation (anammox) plays an important role in aquatic systems as a sink of bioavailable nitrogen (N), and in engineered processes by removing ammonium from wastewater. The isotope effects anammox imparts in the N isotope signatures (1
The effects of liming on nitrogen mineralization and P availability could be magnified in the highly productive humic soils. A large portion of humic soils in KwaZulu-Natal is under sugarcane, where treatment with lime is used to reduce the effects of acidity. The reduction in acidity could ...
