# Pithlachascotee River

The Pithlachascotee River, often called the Cotee or "Cootie" River, is a blackwater river in Pasco County, Florida.
Originating near Crews Lake, the river flows for over 23 miles (37 km) to the south and west, flowing through the Starkey Wilderness Park before turning northwest through downtown New Port Richey, entering the Gulf of Mexico at Miller's Bayou. A Florida State Canoe Trail runs along the river.
On a chart representing the west coast of Florida accompanying the annual report of the U.S. Coast Survey for 1851, the name is translated as "Boat Building River". The whole word signifies the place where canoes were chopped or dug out. The Seminole used canoes dug out of cypress trunks. It is derived from the Creek pithlo (canoe), and chaskita (to chop out).

* 624th Infantry Regiment, Royal Artillery formed by 82nd Light Anti-Aircraft Regiment RA (TA), which had briefly (January–April 1942) seen active service in North Africa as part of 1st Support Group in 1st Armoured Division.
* 639th (Essex Regiment) Infantry Regiment, Royal Artillery formed by 64th (Essex Regiment) Searchlight Regiment, Royal Artillery (TA), which had originally been converted from the 1/6th Battalion, Essex Regiment.

# Security Intelligence Middle East

Security Intelligence Middle East (SIME) (1912–1946) was an organisation made up of a number of British intelligence agencies supporting the British Military Government during the Second World War, based in Cairo, Egypt. It was composed of Security Service (MI5), with Secret Intelligence Service (MI6) provided by liaison officers and army Intelligence Corps personnel (including Field Security teams), but MI5 were the lead agency and provided the focus.
SIME was created in December 1939 as the British Government sought to develop a more focussed approach to counter intelligence and developing security intelligence on the spectrum of threats from espionage, subversion, sabotage and eventually terrorism. SIME's first chief (titled Defence Security Officer) was Colonel Raymond John Maunsell, although he had moved on by February 1945 as he was recorded as being at Supreme Headquarters Allied Expeditionary Force G2 based in northwestern Europe. Another source (Hashimoto) notes that Maunsell's successor to SIME started in 1944, suggesting that Maunsell had moved on by then.
A record of a 1947 visit by two senior Security Service officers to SIME confirmed that it was still based in Cairo and had offices in Baghdad, Jerusalem and Cyprus.
According to Nigel West, Maunsell was succeeded by the following as Chief of SIME, however Hashimoto, in his 2013 doctoral thesis provides dates of service for the other heads of SIME but does not have David Stewart listed. Elsewhere Hashimoto notes that David Stewart had served as Deputy Head of SIME.
* Brigadier Douglas Roberts (1944–2001)
* William (Bill) Morgan Tilson Magan (1947–1951)
* Robin William George Stephens (1951–1953)
* David Stewart
* William (Bill) Oughton (1953–1955)
* Philip Kirby-Green (1955–1958)
The SIME organisational model was in employed elsewhere and in 1946 Security Intelligence Far East (SIFE) was established. SIME was disbanded in 1958.
# Real Life (Jake Owen song)

"Real Life" is a song written by Shane McAnally, Josh Osborne, Ashley Gorley, and Ross Copperman, and recorded by American country music artist Jake Owen. It was originally released as the lead single to his upcoming fifth studio album American Love, but was scrapped in a restructuring of the album after it stalled at number 17 on Country Airplay for several weeks.

## Content

Owen told Billboard and Rolling Stone that the idea for the song came when he discussed his favorite artists with songwriter-producers Shane McAnally and Ross Copperman, mentioning Sublime and Sugar Ray in particular. He also said that he wanted to record a song that differed from his usual beach-related themes, such as "Beachin'" or "The One That Got Away", and that he wanted McAnally and Copperman to give him a song about "real-life situations".
McAnally and Copperman, who produced the song, wrote it with Ashley Gorley and Josh Osborne. It features "relentless acoustic rhythm" and "strange gang vocals and a series of odd-but-familiar images from small-town America: prom queens in plastic crowns, amateurish bar bands and rude Waffle House waitresses." According to Owen, the song is thematically about how "In a world of materialistic things, everybody is constantly looking for what they don't have, as opposed to looking for what's real and what you have right in front of you. That's what 'What We Ain't Got' touched on…'Real Life' is about what we've got and what's real to us."

## Critical reception

Billy Dukes of Taste of Country gave the song a positive review, saying that "Sonically, the arrangement complements the languid, kind of adolescent nature of his lyric and delivery. Owen’s brand of nostalgia isn’t poignant. He’s more recalling the rebellious nature of youth in a way that’s more specific to suburbian(sic) kids that country kids. That’s not to say his songwriting team is lazy with the lyrics — they make clever references throughout “Real Life” and rely on specific, yet somehow universal stories."

## Commercial performance

The song debuted on the Hot Country Songs at number 27 and Country Airplay at number 29 on its released. It also debuted on the Country Digital Songs chart at number 6, selling 29,000 copies in the week. It peaked at number 17 on both Hot Country Songs and Country Airplay for charts of August 15, 2015. The song had sold 274,000 copies in the US as of October 2015.

## Music video

The music video was directed by Jeff Venable and premiered in June 2015. NASCAR driver Kevin Harvick appears in the video.

# Reveal (narrative)

The reveal (also known as the big reveal) is a plot device in narrative structure and is the exposure to the reader or audience of a previously unseen key character, or element of plot or performance.
A reveal is different from Aristotle's anagnorisis, in which something is revealed to a character rather than to the audience.

## Narrative

The reveal may result in a plot twist and could be the key plot turn or unexpected coda in the story; for example, in the mystery genre. It may have scenes in the future that reveal consequences of actions to provide a lead for what will occur in the plot or side plot. This may be the overarching plot line in a mystery or soap opera. It may also be used as a device (particularly in the climax) in stage magic by an illusionist or escape artist.

## Stage magic

In a magician's act, "the reveal" may refer to
* the normal culmination of a trick
* the unexpected (to the audience) culmination of the trick
* an explanation of the trick, which itself may be immediately eclipsed by a version of the trick that the first reveal can't explain.

## Film

Reveal is also used for two distinct cinematographic techniques:
* A slow, theatrically presented image of an important character or item not seen previously in the film;
* A close-up, wide shot, or other unusual camera point-of-view that shows the audience an important visual clue not known to characters in the same scene.
In the sense of first-time showing of a character, a reveal is similar to, but usually not the same as, the opening shot or Establishing shot that gives the location or context of a new scene.
# 3-Penten-2-one

3-Penten-2-one is an organic compound with the formula CH$_3$C(O)CH=CHCH$_3$. It exists as (E) and (Z) stereoisomers. The compound is classified as an α,β-unsaturated ketone. It is a colorless volatile liquid with fruity to pungent odor.

## Preparation, occurrence, uses

The (E) isomer is classically obtained from the 3-chloropentanone by dehydrohalogenation. It can also be obtained by dehydration of 4-hydroxy-pentan-2-one using oxalic acid as a catalyst.
3-Penten-2-one occurs naturally in the berries of two species of Aronia melanocarpa. It has also been found in other plants and foods such as tomatoes, cocoa, tea, and potato chips.
3-Penten-2-one can be used for the synthesis of other compounds such as the alkaloids senepodine G and cermizine C, for example. It is also a useful flavoring agent.
