Tagged Image File Format
TIFF is a computer file format for storing raster graphics images, popular among graphic artists, the publishing industry, and photographers. The TIFF format is widely supported by image-manipulation applications, by publishing and page layout applications, and by scanning, faxing, word processing, optical character recognition and other applications.
The format was created by Aldus Corporation for use in desktop publishing. It published the latest version 6.0 in 1992, subsequently updated with an Adobe Systems copyright after the latter acquired Aldus in 1994. Several Aldus/Adobe technical notes have been published with minor extensions to the format, and several specifications have been based on TIFF 6.0, including TIFF/EP (ISO 12234-2), TIFF/IT (ISO 12639), TIFF-F (RFC 2306) and TIFF-FX (RFC 3949).
History
TIFF was created as an attempt to get desktop scanner vendors of the mid-1980s to agree on a common scanned image file format, in place of a multitude of proprietary formats. In the beginning, TIFF was only a binary image format (only two possible values for each pixel), because that was all that desktop scanners could handle. As scanners became more powerful, and as desktop computer disk space became more plentiful, TIFF grew to accommodate grayscale images, then color images. Today, TIFF, along with JPEG and PNG, is a popular format for high color-depth images.
Nuclear receptor coactivator 2
The nuclear receptor coactivator 2 also known as NCoA-2 is a protein that in humans is encoded by the NCOA2 gene. NCoA-2 is also frequently called glucocorticoid receptor-interacting protein 1 (GRIP1), steroid receptor coactivator-2 (SRC-2), or transcriptional mediators/intermediary factor 2 (TIF2).
Function
NCoA-2 is a transcriptional coregulatory protein that contains several nuclear receptor interacting domains and an intrinsic histone acetyltransferase activity. NCOA2 is recruited to DNA promotion sites by ligand-activated nuclear receptors. NCOA2 in turn acetylates histones, which makes downstream DNA more accessible to transcription. Hence, NCOA2 assists nuclear receptors in the upregulation of DNA expression.
GRIP1 is a transcriptional co-activator of the glucocorticoid receptor and interferon regulatory factor 1 (IRF1).
Interactions
Nuclear receptor coactivator 2 has been shown to interact with:
Titanium tetrafluoride
Titanium(IV) fluoride is the inorganic compound with the formula TiF4. It is a white hygroscopic solid. In contrast to the other halides of titanium, it adopts a polymeric structure consisting of octahedral Ti centres.
Preparation
The traditional method involves treatment of titanium tetrachloride with excess hydrogen fluoride, and purification by sublimation:

Volk (German word)
In German, the word Volk may mean folk (simple people), people in the ethnic sense, and nation.
Volk is commonly used as the first, determining part (head) of compound nouns such as Volksentscheid (plebiscite, literally "decision of/by the people") or Völkerbund (League of Nations), or the car manufacturer Volkswagen (literally, "people's car").
19th century and early 20th century
A number of völkisch movements existed prior to World War I. Combining interest in folklore, ecology, occultism and romanticism with ethnic nationalism, their ideologies were a strong influence on the Nazi party, which itself was inspired by Adolf Hitler's membership of the Deutsche Arbeiterpartei (German Workers' Party), even though Hitler in Mein Kampf himself denounced usage of the word völkisch as he considered it too vague as to carry any recognizable meaning due to former over-use. Today, the term völkisch is largely restricted to historical contexts describing the closing 19th century and early 20th century up to Hitler's seize of power in 1933, especially during the years of the Weimar Republic.
Volk (album)
Volk is the seventh studio album by Slovenian industrial group Laibach. The word Volk means "people" or "nation" in German and "wolf" in Slovene. The album is a collection of thirteen songs inspired by national or pan-national anthems, plus the anthem of the NSK State, a virtual state to which Laibach belong. The album is a collaboration with another Slovenian band Silence.
The album's liner notes credit Wikipedia as their source for information on the national anthems featured.
The anthem of the NSK is essentially the same arrangement as "The Great Seal", a song on their 1987 album Opus Dei. Like "The Great Seal", the words are based on Winston Churchill's famous "We shall fight on the beaches" speech.
The album cover has a double meaning. Its most apparent meaning (for English speakers) is the German word "volk", meaning "nation" or "people". This an allusion to the fascist flirtations of the album. The second meaning is the Slavic word for "wolf". The sheep represent the victims of the wolf.
