Phase diagram of hard sphere system (Solid line - stable branch, dashed line - metastable branch): Pressure as a function of the volume fraction (or packing fraction) The hard sphere system exhibits a fluid-solid phase transition between the volume fractions of freezing η f ≈ 0.494 {\displaystyle \eta _{\mathrm {f} }\approx 0.494} and ...
BAC is generally defined as a fraction of weight of alcohol per volume of blood, with an SI coherent derived unit of kg/m 3 or equivalently grams per liter (g/L). Countries differ in how this quantity is normally expressed.
In most cases the fractionation of polymers on a preparative scale is based on chromatographic methods (e.g. preparative SEC or Baker-Williams fractionation).Therefore, the production is normally limited to few grams only.
An example of a fraction that cannot be represented by a decimal expression (with a finite number of digits) is 1 / 3 , 3 not being a power of 10. More generally, a decimal with n digits after the separator (a point or comma) represents the fraction with denominator 10 n, whose numerator is the integer obtained by removing the separator.
In pharmacology, the volume of distribution (V D, also known as apparent volume of distribution, literally, volume of dilution [1]) is the theoretical volume that would be necessary to contain the total amount of an administered drug at the same concentration that it is observed in the blood plasma.

Conversely the period of the repeating decimal of a fraction c / d will be (at most) the smallest number n such that 10 n − 1 is divisible by d. For example, the fraction 2 / 7 has d = 7, and the smallest k that makes 10 k − 1 divisible by 7 is k = 6, because 999999 = 7 × 142857. The period of the fraction 2 / 7 is ...
Whole-brain ALFF shows greater signal in posterior cingulate, precuneus, and medial prefrontal areas of the default mode network, [2] but also in non-cortical areas near the ventricles, cisterns and large blood vessels. f/ALFF reduces the sensitivity of ALFF to physiological noise by taking the ratio of each frequency (0.01-0.08 Hz) to the total frequency range (0-0.25 Hz).

A total solar eclipse occurred at the Moon's descending node of orbit on Friday, October 3, 1986, [1] with a magnitude of 1. It was a hybrid event, with only a fraction of its path as total, and longer sections at the start and end as an annular eclipse.
