They examined the effects of anoxia on the growth and survival of rice plants.
If a patient suffers cardiac arrest outside a hospital they may die as a consequence of prolonged anoxia.
Accidents involving carbon monoxide poisoning or anoxia will be investigated by a pathologist.
In this dead zone of the bay, the water contains 0.2 mg/litre or less of oxygen, a state called "anoxia".

Examples of anoxia

anoxia
This collapse, we think, would begin at about 20 minutes of true anoxia.
Consuming the remaining oxygen during the initial 20 minutes, the brain cells fall into complete anoxia.
The ischemic focuses, still consuming oxygen, cause central anoxia and anaerobiosis.
Thus, the effects of ischemia cannot be explained simply by an aggregate of the effects of anoxia and aglycemia.
Although not age diagnostic, it demonstrates either stratification within the water column or dysoxia/anoxia within the top layer of sediments.
With anoxia, malate is used as a substrate for anaerobic metabolism and the end product is succinate.
Low levels of oxygen led to anoxia at the sediment-water interface, at least periodically if not continuously.
Alternatively, it could be the result of anoxia in the deeper layers of sediment, which is often associated with sulphate-reducing bacteria.
With physiological suppression, however, older endoparasitoids often have the advantage of eliminating younger competitors through toxic secretions, anoxia or nutrient deprivation.
The ability of a limited number of ectothermal vertebrates and a substantial number of invertebrates to survive long bouts of continuous anoxia is very impressive.
All the simulations show stagnant deep waters which would cause bottom water anoxia.
The distinction may be that water actively circulates in the v'rzea, while swamps tend to lie under stagnant water a prone to anoxia.
The paper stresses the effects of sea-level change, and links to anoxia and ocean circulation, but we learn very little of the carbonate producers themselves.
Interestingly, the development of diapausing pupae is stimulated rather than repressed by anoxia.
Remarkably, during the peak intensity of anoxia within the basins, oxygenpoor water even spread into shallow forereef settings.
