This mimics the process of deep hypothermic circulatory arrest that is achieved when cardiopulmonary bypass machines cool a patient's blood until the oxygen demand of organs and tissue is nearly zero.
Biochemical oxygen demand ( BOD ) is one of the most important indexes in water monitoring.
This paper discussed the influence on the biochemical oxygen demand, ammoniation and nitrosation by barium of different levels in water.
This paper discusses the sources of the uncertainty in measurement of chemical oxygen demand by bichromate determination method.
This paper discusses in detail that coulometry quickly measures chemical oxygen demand of low polluted domestic sewage of the school and high polluted industrial sewage.
Scientists are also eying the Steller sea lion, which redirects blood flow away from non-critical organs during deep sea dives and reduces oxygen demand.
The attenuation of chemical oxygen demand (COD) in rivers during the icebound season was examined, and how the freezing action of ice-layer worked on the attenuation of COD was presented.
The other curve shown in Fig 1.5 corresponds to the biochemical oxygen demand ( BOD ).
