A molecule is said to have a positive oxygen balance if it contains more oxygen than is needed and a negative oxygen balance if it contains less oxygen than is needed. [2] An explosive with a negative oxygen balance will lead to incomplete combustion, which commonly produces carbon monoxide, which is a toxic gas. Explosives with negative or ...

Pre-dive calibration of the cells can only check response to partial pressures up to 100% at atmospheric pressure, or 1 bar. As the set points are commonly in the range of 1.2 to 1.6 bar, [6] special hyperbaric calibration equipment would be required to reliably test the response at the set-points. This equipment is available, but is expensive ...
Dissolved oxygen levels required by various species in the Chesapeake Bay (US). In aquatic environments, oxygen saturation is a ratio of the concentration of "dissolved oxygen" (DO, O 2), to the maximum amount of oxygen that will dissolve in that water body, at the temperature and pressure which constitute stable equilibrium conditions.
O2 purchased Be Un Limited, an internet service provider in the UK, for £50 million in June 2006. [49] O2 retained the Be brand, and launched a separate O2-branded broadband service on 15 October 2007, using the Be network. O2 announced in June 2011 a fibre optic broadband service designed to compete with the BT Infinity product, using FTTC ...

The human body requires and regulates a very precise and specific balance of oxygen in the blood. Normal arterial blood oxygen saturation levels in humans are 96–100 percent. [ 1 ] If the level is below 90 percent, it is considered low and called hypoxemia . [ 2 ]
