The technology can be used wherever industry has a biological waste stream or wastewater with high organic carbon or COD (chemical oxygen demand) of natural origin that can be broken down into biogas by anaerobic bacteria.
The anaerobic wastewater biogas technologies — which extract methane to generate green electricity or to fuel boilers and other factory equipment — are particularly applicable to food, beverage and agribusiness companies, or any industry that has a biological waste stream or wastewater with high organic carbon or COD (chemical oxygen demand) of natural origin that can be broken down into biogas by anaerobic bacteria.
Led by postdoctoral researcher Luis Huckstadt, the researchers found that the dives of pregnant seals became shorter, probably due to an increasing demand for oxygen for the fetus.
Soliman said the finding that atrial fibrillation was associated only with NSTEMI heart attacks suggests that factors contributing to partial blockage of the coronary arteries or increased oxygen demand, such as sudden increase in heart rate, are more likely to explain the association between a-fib and heart attack than those factors linked to total blockage caused by the migration of a blood clot to a coronary artery from the site of its formation.
The country also failed to reduce a measure of water pollution (called «chemical oxygen demand») by 2.0 %.
«Significant impacts to the lake could result from incidental or accidental spills from 5,100 ships passing through every year; invasive species brought by transoceanic ships, which could threaten the extinction of aquatic plants and fish, such as the cichlids that have been evolving since the lake's formation; and frequent dredging, impacting aquatic life through alterations in turbidity and hypoxia, triggered by resuspension of nutrients and organic matter that exert a relatively high biochemical oxygen demand.»
In most cases, hypoxia is caused by either a dysfunction of the retinal vasculature, as in diabetic retinopathy and retinal artery and vein occlusions, or it is due to a mismatch between nutrient supply and demand, as in the case of a retinal detachment, where the retina is separated too far from the choroid to receive sufficient oxygen.
It works by detecting the changes in blood oxygenation and flow that occur in response to neural activity — when a brain area is more active it consumes more oxygen and to meet this increased demand blood flow increases to the active area.
Since the ATP energy used by your muscles is generated with the aid of oxygen, it follows that an increase in exercise intensity will result in an increase in muscular oxygen demands.

Is the effect caused by high biological oxygen demand due to warmer waters?
Biochemical Oxygen Demand (BOD)- The amount of dissolved oxygen consumed by micro-organisms (bacteria) in the bio-chemical oxidation of organic and inorganic matter in waste Oxygen Demand (BOD)- The amount of dissolved oxygen consumed by micro-organisms (bacteria) in the bio-chemical oxidation of organic and inorganic matter in waste oxygen consumed by micro-organisms (bacteria) in the bio-chemical oxidation of organic and inorganic matter in waste water.
