According to Mulholland, a healthy growth of streamside vegetation can diminish the nitrogen and phosphorus load in the stream to the point that it reduces the risk of the nitrogen-driven algal blooms that plague many of the country's lakes and coastal waters.
Landscapes typically deemed at risk from leached losses of nitrogen (N) and phosphorus (P) are those with short subsurface hydrologic time lags.
Substantial improvements have been made to the Canadian Agricultural Nitrogen Budget model (CANB) for estimating residual soil nitrogen (RSN) and the indicator of the risk of water contamination by nitrogen (IROWC-N).
Although the model makes assumptions about the environmental fate of nitrogen that risk oversimplifying matters, says oceanographer Don Boesch of the University of Maryland Center for Environmental Science in Cambridge, Maryland, he calls the conclusions "robust".
Increased risks were associated with use of nitrogen mustard (odds ratio = 9.94, not significant), doxorubicin (odds ratio = 11.25, 0.1 > P > 0.05) and vincristine (odds ratio = 26.57, P < 0.05).
DM, diabetes mellitus; CRP, C-reactive protein; APD, automated peritoneal dialysis; PET, peritoneal equilibration test; NA, non-available; GNRI, geriatric nutritional risk index; nPNA, normalized protein equivalent of nitrogen appearance; MAP, mean arterial pressure; RRF, residual renal function.
A key design feature is focused on the coldest part of sub-cooling HX, where the streams of liquid nitrogen and refrigerant (helium gas) are arranged as two-pass cross-flow so that the risk of freeze-out of liquid nitrogen can be reduced.
The cross-flow heat exchangers are effective in avoiding a complete clog-up of all passages and reducing the risk of freeze-out of liquid nitrogen.
A pilot study of 100 patients in Boston, Massachusetts, found significantly increased risk of ICD discharges associated with nitrogen dioxide and black carbon among patients with repeated events (Peters et al. 2000b).
Decompression sickness is a well-described risk of SCUBA diving in which nitrogen gas dissolved within tissue and blood evolves into gas bubbles upon ascent, resulting in tissue injury (Marx 2006).
