A tenfold dilution for each step is called a logarithmic dilution or log-dilution, a 3.16-fold (10 0.5-fold) dilution is called a half-logarithmic dilution or half-log dilution, and a 1.78-fold (10 0.25-fold) dilution is called a quarter-logarithmic dilution or quarter-log dilution.
For example, on a plot axis showing log 2 fold changes, an 8-fold increase will be displayed at an axis value of 3 (since 2 3 = 8). However, there is no mathematical reason to only use logarithm to base 2, and due to many discrepancies in describing the log 2 fold changes in gene/protein expression, a new term "loget" has been proposed.

Fluorescein aqueous solutions, diluted from 10,000 to 1 parts-per-million in intervals of 10 fold dilution. At 1 ppm the solution is a very pale yellow. At 1 ppm the solution is a very pale yellow. As the concentration increases the colour becomes a more vibrant yellow, then orange, with the final 10,000 ppm a deep red colour.
Concentrations of colony-forming units can be expressed using logarithmic notation, where the value shown is the base 10 logarithm of the concentration. [ 8 ] [ 9 ] [ 10 ] This allows the log reduction of a decontamination process to be computed as a simple subtraction.

Rickey Henderson, who died Friday at age 65, was the standard on the basepaths, setting numerous major league records for stolen bases, including the career mark of 1,406 and the modern single ...
The plot is known as "chevron" plot because of the canonical v, or chevron shape observed when the logarithm of the observed relaxation rate is plotted as a function of the denaturant concentration. In a two-state system, folding and unfolding rates dominate the observed relaxation rates below and above the denaturation midpoint (Cm). This ...
