All of these places, the magazine reports, conform to data that shows the preponderance of urban growth taking place outside the old urban cores. But in its sweeping claim of a âgreat suburbanization,â the report seems to sidestep a central question: What is a suburb, anyway?
Oxygen saturation (symbol SO2) is a relative measure of the amount of oxygen that is dissolved or carried in a given medium.It can be measured with a dissolved oxygen probe such as an oxygen sensor or an optode in liquid media, usually water. The standard unit of oxygen saturation is percent (%).n medicine, oxygen saturation refers to oxygenation, or when oxygen molecules (O 2) enter the tissues of the body. In this case blood is oxygenated in the lungs, where oxygen molecules travel from the air and into the blood.
By mass, oxygen is the third-most abundant element in the universe, after hydrogen and helium. At standardized conditions for temperature and pressure, two atoms of the element bind to form dioxygen, a diatomic gas that is colorless, odorless, and tasteless, with the formula O 2.y mass, oxygen is the third-most abundant element in the universe, after hydrogen and helium.
