AGF may refer to:
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.
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.
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.
The AGF was a small motorcycle manufactured in France between 1948 and 1956 by Andre and George Faizant, who amalgamated their initials to form the company name. The AGF used Ydral engines of 123cc and 173cc.
Breathing is the process that moves air in and out of the lungs, or oxygen through other respiratory organs such as gills. For organisms with lungs, breathing is also called ventilation, which includes both inhalation and exhalation. Breathing is one part of physiological respiration required to sustain life.Aerobic organisms of birds, mammals, and reptiles—require oxygen to release energy via cellular respiration, in the form of the metabolism of energy-rich molecules such as glucose. Breathing is only one of the processes that deliver oxygen to where it is needed in the body and remove carbon dioxide. Another important process involves the movement of blood by the circulatory system.Gas exchange occurs in the pulmonary alveoli by passive diffusion of gases between the alveolar gas and the blood in lung capillaries. Once these dissolved gases are in the blood, the heart powers their flow around the body (via the circulatory system). The medical term for normal relaxed breathing is eupnea.

Ocean Avenue is the fourth studio album by the American rock band Yellowcard. The album was the band's major-label debut and brought them to prominence. It was a commercial success in the United States, led by titular hit single "Ocean Avenue". The album received generally positive reviews from music critics and has been certified platinum in sales by the RIAA and gold by the CRIA. It was produced by Neal Avron, and released on July 22, 2003 through Capitol Records.
In 2013, the band released an acoustic version of the album, Ocean Avenue Acoustic, in honor of the album's tenth anniversary.
Ocean Avenue sold 11,000 copies in its first week in the U.S., debuting at #23. It is Yellowcard's most successful album and has been certified Platinum for sales in excess of 1,000,000. It was released as an enhanced CD in some countries. The enhanced CD includes a video entitled "The Making of Ocean Avenue" and a previously unreleased video of the song "Powder" (from The Underdog EP). In 2005, the album was released as a Special Edition in Malaysia, with live videos and music videos. The album was re-released on limited edition vinyl in 2011.

I wanna save myself from you
You're going under and you're taking me too
I'm starting to disappear
You've gotta let go of my hand
You've got it coming and you don't understand
I'm starting to disappear
So I'm making time for air
I'm breathing in (x 4)
We're all wondering
Where did you go down by the sea?
We're all waiting
For you to come back dry and free
I'm starting to disappear
So I'm making time for air
