Other tests that are useful in determining the extent of CO poisoning include measurement of other arterial blood gases and pH; a complete blood count.

which of the following properties is generally the least useful in identifying minerals
The Great Natchez tornado was never rated. The Fujita scale, which rates tornadoes, was crated in 1971, but has been used to rate tornadoes retrospectively. To rate a tornado you need information on the severity of the damage it did and the quality of construction of the buildings it hit. Unfortunately, as you look at older records, there is generally less useful information. Because of this, no tornado that occurred before 1871 has received a rating. The Natchez tornado was in 1840. That said, by comparing this tornado with other major killers, it is reasonable to say that it was probably an F4 or F5.
It is useful for doing analysis of annual tornado trends. It is also good to have data on the tornadoes kept somewhere in case such records need to be accessed.
the answer is procces of breaking down rock into smaller and smaller sediments
The first blood test for AIDS was developed in 1985. At present, patients who are being tested for HIV infection are usually given an enzyme-linked immunosorbent assay (ELISA) test for the presence of HIV antibody in their blood.
formula for determining the useful life of a building?
It's useful to the commerce and enterprises of the neighbouring cities that have not been affected by the tornado. The term "useful" is obviously relative, once the unique usefulness is that. However, nobody wants such usefulness. The term "usefulness" must be changed here to "consequence". I can't imagine how a tornado or another similar event could be useful.

Useful? Not so much. People can, however, make the most of a bad situation. People who narrowly avoid death may take the encounter as a sign to lead better lives. Following the destruction of a tornado, some communities may rebuild and are to be better than it was before. Usually, though, such efforts do not offset the cost of destruction and suffering.
