Resolution Island (Nunavut)
Resolution Island is one of the many uninhabited Canadian Arctic islands in Qikiqtaaluk Region, Nunavut. It is a Baffin Island offshore island located in Hudson Strait. It has an area of 1,015 km2 (392 sq mi). The Lower Savage Islands lie between Resolution Island and Baffin Island, while Graves Strait separates Resolution Island from the more northern Edgell Island.
History
English explorer Martin Frobisher landed on the island on July 28, 1576, while on a voyage to discover the fabled Northwest Passage. However it appears to have been named Resolution in 1612 by Sir Thomas Button, after his own ship, the Resolution.
The island was home to an American military base, now CFS Resolution Island, that became operational in 1954 as part of the Distant Early Warning (DEW) line. The base was vacated in 1973 and turned over to the Canadian government in 1974.
The Canadian cargo ship named "MINNA" was wrecked on the east side of the island, on 18 August 1974. The vessel was then under charter by the Bedford Institute of Oceanography and was doing scientific surveys at the time of the accident. Badly damaged, the crew and scientific equipment's were removed. Bad weather swept the vessel in deeper waters where she sank on October 2nd 1974. This vessel with a length of 275 feet's and displacement of 4280 tons was based in Halifax and was on regular charter with the BIO for hydrographic surveys on the Labrador Coast and Hudson Strait. The MINNA was built in 1962 and had a crew of 21 men + 18 scientists.
Barium fluoride
Barium fluoride (BaF2) is a chemical compound of barium and fluorine and is a salt. It is a solid which can be a transparent crystal. It occurs in nature as the mineral frankdicksonite.
Structure
The solid adopts the fluorite structure and at high pressure the PbCl2 structure. In the vapor phase the BaF2 molecule is non-linear with an F-Ba-F angle of approximately 108°. This is an exception to VSEPR theory which would predict a linear structure. Ab initio calculations have been cited to propose that contributions from d orbitals in the shell below the valence shell are responsible. Another proposal is that polarisation of the electron core of the barium atom creates an approximately tetrahedral distribution of charge that interacts with the Ba-F bonds.
Applications
Barium fluoride is transparent from the ultraviolet to the infrared, from 150–200 nm to 11–11.5 µm, and can be used as a material to make optical components such as lenses. It is used in windows for infrared spectroscopy, in particular in the field of fuel oil analysis. Its transmittance at 200 nm is relatively low (0.60), but at 500 nm it goes up to 0.96–0.97 and stays at that level until 9 µm, then it starts falling off (0.85 for 10 µm and 0.42 for 12 µm). The refractive index is about 1.46 from 700 nm to 5 µm.

Wie Alles Begann
by: BaffVertraut geleitet an den fremden Ort, ließ ich manches zurück, und bewegte mich fort.
Ein Stück von dort war ein unbekanntes Ziel, das ich so nicht verfolgte, wie in
einem Spiel waren die Regeln verschwommen, es gab nichts zu bekommen, es gab nichts
zu gewinnen, ich ließ mich einfach spinnen, die Zeit verrinnen und sah mir nur zu,
wie mir Fühler wuchsen, deren Grund warst du. Offen und heimlich, aufrecht und
peinlich war der Zufall geplant, entstand so ein Land, das wir oft verließen, öfter
aufeinander stießen, es bei Ahnungen beließen, die uns neues verhießen, deine
Gedanken, die konnten nicht klärn, wer gewinnt. Unser Traum fand die Worte nicht,
die er verdient, doch fand die Neugier ihren eigenen Lohn, und bahnte sich Wege im
Flüsterton.
Wie alles begann, kommt mir dann und wann in den Sinn,
über tausend Mauern führte doch mein Gang zu dir hin.
Was alles geschah, glänzt wieder wie Gold,
Fortsetzung folgt.
Wir liefen los nebeneinander einen schier endlosen Weg, im Wald der Stille die
Hoffnung gesät und gespäht, worin sich der andre verrät, wohin der Pfad geht, wie
die Prüfung gerät. Kühne Gefühle, tanzten nun auf der Bühne, im Keller der
Zweisamkeit wurde es heller, so hell, dass das Augenlicht schreckte, versteckte
Signale, die ich dir zum Leuchtfeuer erweckte. Verwebte Erwartung gesteigert,
erweitert die Sinne, war uns an der Stelle der Schwelle der Zutritt verweigert, der
Anfang vom Ende das Ende vom Ende und mit ihm die Wende.
Wie alles begann, kommt mir dann und wann in den Sinn,
über tausend Mauern führte doch mein Gang zu dir hin.
Was alles geschah, glänzt wieder wie Gold,
Fortsetzung folgt
Die Sinne, die wurden uns neu geboren, verborgene Dinge verborgen geborgen. Der
Morgen danach war ein Morgen davor, ein Endpunkt wurde zum glänzenden Tor. Die
Eindrücke füllten uns unsere Seelen, verhüllte Gefühle warn nun anzusehen, freizügig
zu stehlen aus unendlichem Schatz - unsre Heimat nahm Platz.
