A variety of different kinds of IEC 60320 plugs and sockets. IEC 60320 Appliance couplers for household and similar general purposes [1] is a set of standards from the International Electrotechnical Commission (IEC) specifying non-locking connectors for connecting power supply cords to electrical appliances of voltage not exceeding 250 V (a.c.) and rated current not exceeding 16 A.

The results from AMS testing are in the form of ratios of 12 C, 13 C, and 14 C.These ratios are used to calculate F m, the "fraction modern", defined as = where R norm is the 14
Carbon-14, C-14, 14 C or radiocarbon, is a radioactive isotope of carbon with an atomic nucleus containing 6 protons and 8 neutrons.Its presence in organic matter is the basis of the radiocarbon dating method pioneered by Willard Libby and colleagues (1949) to date archaeological, geological and hydrogeological samples.
The Suess effect is a change in the ratio of the atmospheric concentrations of heavy isotopes of carbon (13 C and 14 C) by the admixture of large amounts of fossil-fuel derived CO 2, which contains no 14 CO 2 and is depleted in 13 CO 2 relative to CO 2 in the atmosphere and carbon in the upper ocean and the terrestrial biosphere .

Radiocarbon dating helped verify the authenticity of the Dead Sea scrolls.. Radiocarbon dating (also called carbon dating or carbon-14 dating) is a method for determining the age of an object containing organic material by using the properties of carbon-14 (radiocarbon, 14 C), a radioactive isotope of carbon.
