AGF
AGF may refer to:
Silver(II) fluoride
Silver(II) fluoride is a chemical compound with the formula AgF2. It is a rare example of a silver(II) compound. Silver usually exists in its +1 oxidation state. It is used as a fluorinating agent.
Preparation
AgF2 can be synthesized by fluorinating Ag2O with elemental fluorine. Also, at 200 °C (473 K) elemental fluorine will react with AgF or AgCl to produce AgF2.
As a strong fluorinating agent, AgF2 should be stored in Teflon or a passivated metal container. It is light sensitive.
AgF2 can be purchased from various suppliers, the demand being less than 100 kg/year. While laboratory experiments find use for AgF2, it is too expensive for large scale industry use. In 1993, AgF2 cost between 1000-1400 US dollars per kg.
Composition and structure
AgF2 is a white crystalline powder, but it is usually black/brown due to impurities. The F/Ag ratio for most samples is < 2, typically approaching 1.75 due to contamination with Ag and oxides and carbon.
For some time, it was doubted silver was actually in the +2 oxidation state rather in some combination of states such as AgI[AgIIIF4], which would be similar to silver(I,III) oxide. Neutron diffraction studies, however, confirmed its description as silver(II). The AgI[AgIIIF4] was found to be present at high temperatures, but it was unstable with respect to AgF2.
USS La Salle (AGF-3)
The second USS La Salle (LPD-3/AGF-3) was built as a Raleigh-class amphibious transport dock and later served as a command ship in the United States Navy.
La Salle was named for the city in Illinois that was in turn named after René-Robert Cavelier, Sieur de La Salle.
Her keel was laid down by New York Naval Shipyard, Brooklyn, New York, on 2 April 1962. She was launched on 3 August 1963 sponsored by Mrs. Victor M. Longstreet, and commissioned on 22 February 1964 with Captain Edward H. Winslow, USN in command.
Service history
Amphibious transport, 1964–1972
After shakedown and training in the Caribbean Sea and off Norfolk, Virginia, the amphibious transport dock departed Norfolk on 9 October to participate in "Operation Steel Pike I", a complex training exercise involving over 80 ships and United States and Spanish troops. It closed the coast of Spain off Huelva on 26 October, and embarked Under Secretary of the Navy Paul B. Fay, Vice Chief of Naval Operations Admiral Horacio Rivero, Commandant of the Marine Corps General Wallace M. Greene, and Chairman of the House Armed Services Committee Congressman Mendel Rivers to watch the landing operations.
Geneva
Geneva (/dʒᵻˈniːvə/, French: Genève [ʒə.nɛv], Arpitan: Genèva [dzəˈnɛva], German: Genf [ɡɛnf], Italian: Ginevra [dʒiˈneːvra], Romansh: Genevra) is the second most populous city in Switzerland (after Zürich) and is the most populous city of Romandy, the French-speaking part of Switzerland. Situated where the Rhône exits Lake Geneva, it is the capital of the Republic and Canton of Geneva.
The municipality (ville de Genève) has a population (as of December 2014) of 197,376, and the canton (which is essentially the city and its inner-ring suburbs) has 482,545 residents. In 2011, the compact agglomération franco-valdo-genevoise (Greater Geneva or Grand Genève) had 915,000 inhabitants in both – Switzerland and France (< 30mins distance). Within Swiss territory, the commuter area named "Métropole lémanique" contains a population of 1.25 million. This area is essentially spread east from Geneva towards the Riviera area (Vevey, Montreux) and north-east towards Yverdon-les-Bains, in the neighbouring canton of Vaud (< 60mins distance).
Geneva (band)
Geneva were a British alternative rock band from Aberdeen, Scotland.
Career
The band were formed in 1992 by vocalist Andrew Montgomery and guitarist Steven Dora. They recruited second guitarist Stuart Evans, bass player Keith Graham and finally drummer Craig Brown. Craig was later replaced by Douglas Caskie. Originally the band were called Sunfish.
One of their demos found their way to Suede’s record label, Nude, who signed the band in 1996. The band changed their name, originally to Garland, then later to Geneva, and released their debut single "No One Speaks" the same year. The band garnered enough press to headline NME's annual Bratbus tour of up and coming bands in early 1997. The band released second single "Into the Blue" to coincide with the tour.
Musical style
The band fitted well with the current musical scene and were well promoted by the UK music press of the time. As a reaction to the fading Britpop scene many bands rejected the laddish ideals of bands like Oasis and wrote darker, more intelligent songs, in the vein of contemporaries such as Gene and Strangelove. Montgomery’s relatively high-pitched vocals were often compared to Suede's Brett Anderson.
Geneva station (Illinois)
Geneva is a Metra commuter railroad station in Geneva, Illinois served by Metra's Union Pacific/West Line. The station is 35.5 miles (57.1 km) away from Ogilvie Transportation Center. In Metra's zone-based fare structure, Geneva is in zone H.
The station consists of two side platforms and a waiting room, with a ticket agent booth staffed on weekday mornings. Trains go east to Ogilvie Transportation Center in Chicago and west to Elburn, Illinois. Until the line's extension to Elburn in 2006, Geneva was the western terminus of the Union Pacific/West Line.
Until 2006 and the line's extension, half of the weekend trains started at West Chicago. Since then, all those trains were moved to Elburn, leaving all trains to serve Geneva.
