The Newport Ship is a mid-fifteenth-century sailing vessel discovered when archaeologists investigated an articulated timber structure uncovered during the building of the Riverfront Arts Centre in Newport in June 2002. The site is on the west bank of the River Usk, which runs through the city centre.
Christopher Newport (1561–1617) was an English seaman and privateer. He is best known as the captain of the Susan Constant, the largest of three ships which carried settlers for the Virginia Company in 1607 on the way to found the settlement at Jamestown in the Virginia Colony, which became the first permanent English settlement in North America.
Iron-60 is an iron isotope with a half-life of 2.6 million years, [12] [13] but was thought until 2009 to have a half-life of 1.5 million years. It undergoes beta decay to cobalt-60, which then decays with a half-life of about 5 years to stable nickel-60. Traces of iron-60 have been found in lunar samples.
Capacity of 41, 22 in normal service. Aviation facilities. Landing pad for medium helicopter. USNS Newport (T-EPF-12) is the twelfth Spearhead -class expeditionary fast transport and is operated by the United States Navy ' s Military Sealift Command. [2][6] It is the fourth ship in naval service named after Newport, Rhode Island. [6]
There are seven stable isotopes of mercury (80 Hg) with 202 Hg being the most abundant (29.86%). The longest-lived radioisotopes are 194 Hg with a half-life of 444 years, and 203 Hg with a half-life of 46.612 days. Most of the remaining 40 radioisotopes have half-lives that are less than a day. 199 Hg and 201 Hg are the most often studied NMR ...

Isotopes of neon. In addition, 17 radioactive isotopes have been discovered, ranging from 15. , all short-lived. The longest-lived is 24. with a half-life of 3.38 (2) min. All others are under a minute, most under a second. The least stable is 15. with a half-life of 770 (300) ys (7.7 (3.0) × 10−22 s). See isotopes of carbon for notes about ...
Island of stability. A diagram by the Joint Institute for Nuclear Research showing the measured (boxed) and predicted half-lives of superheavy nuclides, ordered by number of protons and neutrons. The expected location of the island of stability around Z = 112 (copernicium) is circled. [1][2] In nuclear physics, the island of stability is a ...
