However, log-ratios are often used for analysis and visualization of fold changes. The logarithm to base 2 is most commonly used, [ 8 ] [ 9 ] as it is easy to interpret, e.g. a doubling in the original scaling is equal to a log 2 fold change of 1, a quadrupling is equal to a log 2 fold change of 2 and so on.
Churchill equation [24] (1977) is the only equation that can be evaluated for very slow flow (Reynolds number < 1), but the Cheng (2008), [25] and Bellos et al. (2018) [8] equations also return an approximately correct value for friction factor in the laminar flow region (Reynolds number < 2300). All of the others are for transitional and ...
In British Columbia, the Range Regulation defines "animal unit month" for purposes of the Range Act. Effectively, the regulation assigns animal unit equivalents of 1 for a cow (either by herself or with an unweaned calf), 0.7 for a yearling of the genus Bos, 1.5 for a bull, 1.25 for a horse, 0.2 for a sheep, 0.2 for a llama, and 0.1 for an alpaca.
The first lists show the most recent year where there is published total fertility rate (TFR) data ranked by sovereign states and dependencies, and are ordered by organization type – intergovernmental, governmental, or non-governmental organization that searched, organized, and published the data.
The lower quartile, Q 1, is a number such that integral of the PDF from -∞ to Q 1 equals 0.25, while the upper quartile, Q 3, is such a number that the integral from -∞ to Q 3 equals 0.75; in terms of the CDF, the quartiles can be defined as follows: = (),

In mathematics, exponentiation, denoted b n, is an operation involving two numbers: the base, b, and the exponent or power, n. [1] When n is a positive integer, exponentiation corresponds to repeated multiplication of the base: that is, b n is the product of multiplying n bases: [1] = ⏟.
