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.
Photosynthesis can cause the water to have more dissolved oxygen than the saturation amount. When that happens it is called supersaturation. Animals, such as fish, breathing in the water consume dissolved oxygen.old water can hold more dissolved oxygen than warm water and fresh water can hold more dissolved oxygen than salt water. So the warmer and saltier the water, the less dissolved oxygen there can be. The maximum amount of dissolved oxygen that the water can hold is called the saturation value.
