seizures ('while breathholding'): nonepileptic vagal attacks.
By contrast, F3 in [S.sub.IN] exhibited a significant increase within the first 3 d and then decreased, indicating that the redistribution of F3 in iron-amended soils under anoxic
"We don't know if the ocean is headed toward another global anoxic
event, but the trend is, of course, worrying."
On day 160 (Stage II) a failure of the aeration system caused that the system operated under anoxic
conditions for more than 48 h and nitrite concentration in the reactor decreased from around 200 to 100 mg N[O.sub.2.sup.-]-N/L (Figure 2(a)).
(1996) to identify, on the basis of the OAEs definition by Jenkyns and Clayton (1986, 1997) the presence of an "anoxic
" event of Pliensbachian age in the Asturian Basin.
At night, oxygen is rapidly consumed by aerobic degradation, resulting in anoxic
conditions (Kayombo et al., 2002; Tadesse et al., 2004) and allowing several cyanobacteria genera, such as Oscillatoria, to dominate.
The part of raw carbon sewage from influent is utilized for upstream denitrification in the pre anoxic
chamber, before reaching the oxidation chamber, while the downstream denitrification utilizes endogenous carbon source from the aerobic process [6, 20].
Although delayed post-hypoxic leukoencephalopathy is considered rare, consider it in the differential diagnosis when a patient has a recent history of an anoxic
event followed by the abrupt onset of neuropsychiatric symptoms.
It is obvious that the oceanic setting at the time of black shale formation was anoxic
; hence the expression "Oceanic Anoxic
Event" was introduced to denote the events in the mid-1970s.
Denitrification reaction in which carbon sources are required occurs under anoxic
Compared with the conventional process linking BNR with chemical precipitation, the advantages of the new process may display: (a) a P-rich supernatant generated by denitrifying polyphosphate accumulating organisms (DPAO) in the anaerobic tank, included the BNR-IC system, omitting the procedure of anaerobic sludge digestion; (b) the crystallization product can be dewatered easily and could be potentially used directly as phosphorus fertilizer or industrial raw materials; (c) moreover, the induced HAP crystallization section can greatly reduce the P loading in the anoxic
environment (presenting the excessive P uptake by DPAO), thus resulting in a minimize sludge production.
The examiner listed the official cause of death as anoxic
encephalopathy due to hypoxic arrest - a condition caused when brain tissue is deprived of oxygen leading to damage.
