Recognized effects of higher acute radiation doses are described in more detail in the article on radiation poisoning.Although the International System of Units (SI) defines the sievert (Sv) as the unit of radiation dose equivalent, chronic radiation levels and standards are still often given in units of millirems (mrem), where 1 mrem equals 1/1,000 of a rem and 1 rem equals 0.01 Sv.
σ x should usually be quoted to only one or two significant figures, as more precision is unlikely to be reliable or meaningful: 1.79 ± 0.06 (correct), 1.79 ± 0.96 (correct), 1.79 ± 1.96 (incorrect). The digit positions of the last significant figures in x best and σ x are the same, otherwise the consistency is lost. For example, "1.79 ± ...
[4] Similar to the previous month, activity during the beginning of the month was mainly due to the tropics as Hurricane Debby spawned 24 tornadoes. Simultaneous tornado activity also occurred in the Midwestern United States and Great Lakes region during that time. However, tornado activity then went dormant until the last few days of the month ...
[3] [2] BAC levels above 0.40% (4 g/L) can be potentially fatal. [1] According to Guinness World Records, 1.374% (13.74 g/L) is the highest BAC ever recorded in a human who survived the ordeal. [4] The record was set in July 2013 by an unidentified Polish man found unconscious by the side of a road in the village of Tarnowska Wola, in south ...
Z tables use at least three different conventions: . Cumulative from mean gives a probability that a statistic is between 0 (mean) and Z.Example: Prob(0 ≤ Z ≤ 0.69) = 0.2549.
The main objective of interval arithmetic is to provide a simple way of calculating upper and lower bounds of a function's range in one or more variables. These endpoints are not necessarily the true supremum or infimum of a range since the precise calculation of those values can be difficult or impossible; the bounds only need to contain the function's range as a subset.

The Stanton number is a useful measure of the rate of change of the thermal energy deficit (or excess) in the boundary layer due to heat transfer from a planar surface.
