The world best time for a "football 40" is 4.17 by Deion Sanders, while the extrapolated best for an Olympic-level athlete (including reacting to a starting gun) is 4.24 by Maurice Greeneat the 2001 World Championships in Athletics. [255][256]Under conventional football timing on a turf field in 2017, Christian Colemanreportedly ran a 4.12.
The codes given in the chart below usually tell the length and width of the components in tenths of millimeters or hundredths of inches. For example, a metric 2520 component is 2.5 mm by 2.0 mm which corresponds roughly to 0.10 inches by 0.08 inches (hence, imperial size is 1008).
This is a list of abbreviations used in medical prescriptions, including hospital orders (the patient-directed part of which is referred to as sig codes). This list does not include abbreviations for pharmaceuticals or drug name suffixes such as CD, CR, ER, XT (See Time release technology § List of abbreviations for those).

[1] It refers to the "recurrent and intense sexual arousal from the act of being humiliated, beaten, bound, or otherwise made to suffer, as manifested by fantasies, urges, or behaviors" (p. 694).
A reference designator unambiguously identifies the location of a component within an electrical schematic or on a printed circuit board. The reference designator usually consists of one or two letters followed by a number, e.g. C3, D1, R4, U15. The number is sometimes followed by a letter, indicating that components are grouped or matched with ...
The free androgen index is intended to give a guide to the free testosterone level, but it is not very accurate (especially in males — see endocrine society commentary below). Consequently, there are no universally agreed 'normal ranges', and levels slightly above or below quoted laboratory reference ranges may not be clinically significant.
Crystal oscillators can be manufactured for oscillation over a wide range of frequencies, from a few kilohertz up to several hundred megahertz.Many applications call for a crystal oscillator frequency conveniently related to some other desired frequency, so hundreds of standard crystal frequencies are made in large quantities and stocked by electronics distributors.
