One subclade of haplogroup R1b (especially R1b1a2), is the most common haplogroup in Western Europe and Bashkortostan ( Lobov 2009 ), while a subclade of haplogroup R1a (especially haplogroup R1a1 ) is the most common haplogroup in large parts of South Asia , Eastern Europe , Central Asia , Western China ...
A Fixture Unit is not a flow rate unit but a design factor. A fixture unit is equal to 1 cubic foot (0.028 m 3) of water drained in a 1 + 1 ⁄ 4 inches (32 mm) diameter pipe over one minute. [2] One cubic foot of water is roughly 7.48 US gallons (28.3 L; 6.23 imp gal). A Fixture Unit is used in plumbing design for both water supply and waste ...

The genetic divergence of R1a (M420) is estimated to have occurred 25,000 [2] years ago, which is the time of the last glacial maximum.A 2014 study by Peter A. Underhill et al., using 16,244 individuals from over 126 populations from across Eurasia, concluded that there was "a compelling case for the Middle East, possibly near present-day Iran, as the geographic origin of hg R1a".

For hoses and piping, a quick connect fitting, also called a push fitting, is a coupling used to provide a fast, make-or-break connection of gas or liquid transfer lines. Operated by hand, quick connect fittings replace threaded or flanged connections, which require wrenches. When equipped with self-sealing valves, quick connect fittings will ...
