This relative stability was ended by the sacking of Constantinople during the Fourth Crusade ( 1204 ) and during the turmoil of the 13th century the island ownership was constantly affected by the regional power struggles.

Immigration policy does not provoke much debate in Mauritius, and the relative economic stability of the island serves to attract foreign workers.

Given its long stability and isolation, New Caledonia serves as a unique island refugium — a sort of biological ' ark ' — hosting a unique ecosystem and preserving Gondwanan plant and animal lineages no longer found elsewhere.

Further anomalous elements in this series have been predicted by Glenn T. Seaborg, and are categorised as the “ island of stability .”

The so-called island of stability may reveal a number of long-lived or even stable atoms that are heavier ( and with more protons ) than lead.

Due to some variations in orbital filling, the upper magic numbers are 126 and, speculatively, 184 for neutrons but only 114 for protons, playing a role in the search of the so-called island of stability.

Tremendous prosperity on the island was accompanied by economic and social stability.

Ununoctium comes right at the end of the " island of stability " and thus its nuclei are slightly more stable than otherwise predicted.

Nevertheless, because of reasons not very well understood yet, there is a slight increased nuclear stability around atomic numbers 110 – 114, which leads to the appearance of what is known in nuclear physics as the " island of stability ".

Nonetheless, this is still longer than some predicted values, thus giving further support to the idea of this " island of stability ".

3-dimensional rendering of the theoretical island of stability around N = 178 and Z = 118

The possibility of an " island of stability " was first proposed by Glenn T. Seaborg in the late 1960s

Unbinilium is of interest because it is part of the hypothesized island of stability, with the compound nucleus < sup > 302 </ sup > Ubn being the most stable of those that can be created directly by current methods.

Thus the resulting nuclei become heavier and closer to the sought-after island of stability, a concept wherein some super-heavy atoms can be relatively stable.

The ununseptium synthesis serves as definite proof of the existence of the " island of stability ", according to the discoverers.

Nevertheless, because of reasons not very well understood yet, there is a slight increased nuclear stability around atomic numbers 110 – 114, which leads to the appearance of what is known in nuclear physics as the " island of stability ".

Elements in this region are likely to be highly unstable with respect to radioactive decay, and have extremely short half lives, although element 126 is hypothesized to be within an island of stability that is resistant to fission but not to alpha decay.

It is not clear how many elements beyond the expected island of stability are physically possible, if period 8 is complete, or if there is a period 9.

A low estimate is that the periodic table may end soon after the island of stability, which is expected to center around Z = 126, as the extension of the periodic and nuclides tables is restricted by the proton and the neutron drip lines ; however, some, such as Walter Greiner, predict that there may not be an end to the periodic table at all.

Soon, Godzilla appears on an island off the coast of Japan, determined to feed off a nuclear power plant there.

In the late 1960s, the U. S. had plans for an underground nuclear weapon test in the tectonically unstable island of Amchitka in Alaska.

The United Kingdom detonated some of nuclear payload near and directly above Christmas Island in 1957 / 58, while the United States between 25 April and 11 July 1962 successfully tested nuclear devices of about payload altogether in the vicinity of the island.

* 1962 – The Cuban Missile Crisis begins: A U. S. Air Force U-2 reconnaissance plane and its pilot fly over the island of Cuba and take photographs of Soviet missiles capable of carrying nuclear warheads being installed and erected in Cuba.

This test is known as a " calibration shot " to test if the island is fit for larger underground nuclear detonations.

To counter this threat, Castro forged an economic and military alliance with the Soviet Union and allowed them to place nuclear weapons on the island, leading to the events of the Cuban Missile Crisis in 1962.

Although the story follows the same general storyline, there are some changes: the film shows Dr. No to be an operative of SPECTRE and his island fortress is nuclear powered ; No is killed not by the mountain of guano, but by drowning in reactor coolant.

In the north west of the island at (), a missile testing range was built in 1957-58 to launch the Corporal missile, Britain and America's first guided nuclear weapon.

In the 1950s, the United States threatened to use nuclear weapons against the PRC if it attacked the island.

Examples include HMS Excellent, which is a training school located on an island in Portsmouth Harbour, and, in Caithness in the Highland area of Scotland, which is established to test the design of nuclear power systems for use in submarines.

In 1971 he joined the crew member of the Greenpeace boat sailing to protest against U. S. army nuclear bomb test near Amchitka island.

Before the 1972 reversion of the island to Japanese administration, it has been speculated but never confirmed that up to 1, 200 nuclear weapons may have been stored at Kadena Air Base, Okinawa in the 1960s.

Two of Finland's four nuclear reactors are on the island of Olkiluoto in Eurajoki, and a third one is under construction.

" Early on he opposed the Anglo-American military installation on the nearby island of Diego Garcia because of the possible storage of nuclear weapons and alleged detention of terrorist suspects at that location.

Notably, it was the example set by the voyages of the Golden Rule and the Phoenix that would inspire the first Greenpeace activists to use similar methods in their campaigns to halt nuclear testing at the island of Amchitka, Alaska, and at Muraroa Atoll in the Pacific.

Arno women are renowned for their production of the Kili Bag, a popular handwoven handbag / purse, named after another island in the Marshall Islands ( to which the people of Bikini were eventually relocated as a result of the US nuclear tests that were conducted on their home atoll ).

In May 2005 the group squatted on Drake's Island, a privately owned island in Plymouth Sound declaring it a " nuclear free state " in order to " highlight Britain's hypocrisy over the non proliferation treaty talks being held in New York ".

However, with Kwajalein island used as a support base for the nuclear tests conducted at Bikini Atoll and Enewetak Atoll, Marshallese residents of Kwajalein were relocated by U. S. authorities to a small, planned community constructed on Ebeye, which was largely unpopulated and had served as a Japanese seaplane base prior to the Pacific War.

In January 2260 – 61 the island of Selini in the southern hemisphere of the planet was used as a staging ground for over a hundred Shadow ships, until shortly afterwards then-Prime Minister Londo Mollari destroyed this island using fusion-based nuclear bombs.
