Because a PaO2 level of 90 or 80 mm Hg is still a good level to be at, while both 50 and 40 mm Hg both indicate moderate hypoxemia. It's even more critical because at 50 mm Hg, the body is already lacking oxygen, if the level decreases further to 40 mm Hg it's even further stressed and is borderline severe hypoxemia.
An inequality must have a greater than sign (>) OR a less than sign (<) OR a greater than or equal to sign (≥) OR a less than or equal to sign (≤).
For satllite communication the frequency should not be less than the critical frequency because in satellite communicaton high frequency is needed which is reflected by satellite but not by the ionosphere.
Less than consumption of
it's much less than the pecentage that drop out of public high schools
That you should drop your keys less often...? you should get better hands.
like a eye drop bottle
When the platelet count falls to less than 100,000mm3
Definitely LESS energy than a huge iceberg.
critical data is often less available and less dependable.
At less than critical mass, there are fewer "targets" for neutrons to strike, fission, and release more neutrons. As a result, the reaction dies out.
Not alot. Differs each time but it will be less than 5m
I would suggest using light weight materials and also very small ones. I am also doing an Egg Drop, but it's less strict on the inches/centimeters.
