Apúlia e Fão is a civil parish in the municipality of Esposende, Portugal. It was formed in 2013 by the merger of the former parishes Apúlia and Fão. The population in 2011 was 7,301, in an area of 16.29 km².
Dioxygen difluoride is a compound of fluorine and oxygen with the molecular formula O
2F
2. It exists as an orange solid that melts into a red liquid at −163 °C (110 K). It is an extremely strong oxidant and decomposes into oxygen and fluorine even at −160 °C (113 K) at a rate of 4% per day: its lifetime at room temperature is thus extremely short. Dioxygen difluoride reacts with nearly every chemical it encounters – even ordinary ice – leading to its onomatopoeic nickname "FOOF" (a play on its chemical structure).
The material has no practical applications, but has been of theoretical interest. One laboratory's use of it was the synthesis of plutonium hexafluoride at unprecedentedly low temperatures, which was significant because previous methods for its preparation needed temperatures so high that the plutonium hexafluoride created would rapidly decompose.
Dioxygen difluoride can be obtained by subjecting a 1:1 mixture of gaseous fluorine and oxygen at low pressure (7–17 mmHg is optimal) to an electric discharge of 25–30 mA at 2.1–2.4 kV.
A similar method was used for the first synthesis by Otto Ruff in 1933. Another synthesis involves mixing O
2 and F
2 in a stainless steel vessel cooled to −196 °C (77.1 K), followed by exposing the elements to 6987480652946100000♠3 MeV bremsstrahlung for several hours. A third method requires heating a mix of fluorine and oxygen to 700 °C (1,292 °F), and then rapidly cooling it using liquid oxygen. All of these methods involve synthesis according to the equation:

2000 O.D is a Space Tribe album published in 1999 by Spiritzone.
O.D. is one of the founders of the industrial/metal/electronic band Velcra. He has worked on samples/programming and guitars on the band's first two albums and is the main producer on their third album.
F.O.O.D., released under Danny!'s 1911 Music/Badenov Records imprint in 2005 (see 2005 in music), is the second full-length studio album from the American rapper/producer. The acronym "F.O.O.D." stands for "Finding Out Our Destination" and, despite the depiction in the cover art, the album's content has nothing to do with any actual food or food-related themes (unlike MF Doom's second album, MM..Food).
The restaurant shown on the cover of F.O.O.D. is Bobbie's Diner, a 1950s-themed cafe owned by the Savannah College of Art & Design where Danny! was once a student.
The album, which was pressed up in limited quantities, was significant for officially introducing the wise-ass/sarcastic and cynical persona of Danny!, now known by the alternative moniker and alter ego "D. Swain". This was largely in part due to the mixed criticism Danny! received for his debut album, The College Kicked-Out. The jaded producer/MC took the feedback personally, openly lashing out on his critics throughout F.O.O.D. It was this, along with constant usage of self-deprecating lyrics that bordered on autophobia and smacked of depression, that made F.O.O.D. a far darker and more emotionally charged LP than its predecessor.
