Head (vessel)

A head is one of the end caps on a cylindrically shaped pressure vessel.

Shapes

The shape of the heads used can vary. The most common head shapes are:

Hemispherical head

A sphere is the ideal shape for a head, because the pressure in the vessel is divided equally across the surface of the head. The radius (r) of the head equals the radius of the cylindrical part of the vessel.

Ellipsoidal head

This is also called a 2:1 elliptical head. The shape of this head is more economical, because the height of the head is just a quarter of the diameter. Its radius varies between the major and minor axis.

Torispherical head

These heads have a dish with a fixed radius (r1), the size of which depends on the type of torispherical head. The transition between the cylinder and the dish is called the knuckle. The knuckle has a toroidal shape. The most common types of torispherical heads are:

Klöpper head

This is a torispherical head. The dish has a radius that equals the diameter of the cylinder it is attached to (). The knuckle has a radius that equals a tenth of the diameter of the cylinder (), hence its alternative designation "Decimal head".

Head (The Monkees album)

Head is the soundtrack to the film Head, the only theatrical release by The Monkees. Released in 1968 through Colgems, it was the band's sixth album. Head was the last Monkees album to feature Peter Tork till Pool It! in 1987, and the last to feature all four Monkees until 1996's Justus.

The soundtrack album intersperses the six full-length songs ("Porpoise Song", "Circle Sky", "Can You Dig It?", "As We Go Along", "Daddy's Song" and "Long Title: Do I Have to Do This All Over Again?") with bits of Ken Thorne's incidental music, dialogue fragments, and sound effects culled from the film. The selection of music and dialogue approximates the flow of the movie itself, and was compiled by actor Jack Nicholson, who co-wrote the film's shooting script.

In 2013, Rolling Stone ranked the album at number 25 in their list of "The 25 Greatest Soundtracks of All Time".

History

The music of The Monkees often featured rather dark subject matter beneath a superficially bright, uplifting sound. The music of the film takes the darkness and occasional satirical elements of the Monkees' earlier tunes and makes it far more overt, as in "Ditty Diego/War Chant", or "Daddy's Song", which has Jones singing an upbeat, Broadway-style number about a boy abandoned by his father. In his 2012 essay on the soundtrack album, academic Peter Mills observed that "on this album the songs are only part of the story, as they were with The Monkees project as a whole: signals, sounds, and ideas interfere with each other throughout."

Head (music)

In its broadest sense, the head of a piece of music is its main theme, particularly in jazz, where the term takes on a more specific set of connotations. In other types of music, "head" may refer to the first or most prominent section of a song. The term may, though obtusely, be applied to classical music, insofar as classical pieces generally bear similar thematic elements, but the preferred term in this instance is (main) theme or subject. The term "head" is most often used in jazz and may refer to the thematic melody, an instance of it in a performance of the song, or a more abstract compilation of ideas as to what the song is. It may also, though uncommonly, refer to the first section of the melody, or the theme riff in the melody.

There is a slightly related musical direction, D.C. or da capo (Italian, from head), which means to go back to the very beginning of the sheet music and play to the end, typically ignoring all repeat signs.

What's in a head

The idea a head represents comprises a combination of elements. No one piece of written music defines what the "head" of many jazz tunes really is, but a boiler-plate jazz chart, which is often only a page long in large print, will tell you:

Thunder (ship)

FV Thunder was an outlaw fishing vessel sunk in 2015. The ship was built in 1969 in Norway and has gone by many names, including: Vesturvón, Arctic Ranger, Rubin, Typhoon I, Kuko, and Wuhan N4. The ship was last registered in Lagos, Nigeria; however, the ship was officially de-listed by Nigeria a week before it sank.

At the time of its sinking, the crew consisted of 30 Indonesians and 10 officers from Spain, Chile, and Portugal, who were turned over to the authorities in São Tomé and Príncipe. The officers of the crew were later tried and convicted of several illegal fishing offences. The captain, Luis Alfonso Rubio Cataldo of Chile, was given a three year sentence. The ship's chief engineer, Agustín Dosil Rey of Spain, was given a two year and nine month sentence. The ship's second mechanic, Luis Miguel Pérez Fernández of Spain, was given a two year and eight month sentence. Together, they were fined a total of over $17 million.Interpol believes that the vessel was part of a fleet of six operating through shell corporations under Vidal Armadores, a company based in Spain.

Thunder (film)

Thunder is a 1929 American silent melodrama film starring Lon Chaney and directed by William Nigh. The film has no audible dialogue but featured a synchronized musical score and sound effects.Thunder was Chaney's penultimate film appearance and his last silent film.

The majority of Thunder is now considered lost, with only a half a reel of the entire footage known to survive.

Synopsis

Lon Chaney plays Grumpy Anderson, a railroad engineer with an obsession for running his train on time. His slavishness to promptness causes several tragedies which alienate him from his family. Fortunately, by the story's end, the engineer restores their faith in him and validates his obsession by forcing his train through a flood to bring badly needed Red Cross supplies to the victims.

Cast

Production notes

The film was shot on location in Manitowoc, Wisconsin, Green Bay, Wisconsin, Pulaski, Wisconsin, Green Valley, Wisconsin, and Chicago, Illinois. It was there that Chaney caught a cold during the snow scenes which then developed into walking pneumonia. Production was shut down for a time but was eventually completed. Chaney's illness combined with his throat cancer led to his death two months after the release of his last film, and only talkie, 1930's The Unholy Three.

Girls (Beastie Boys song)

"Girls" is a song by American hip hop group the Beastie Boys, released in 1987 as well as the music video as the seventh and final single from their debut album Licensed to Ill. Like "(You Gotta) Fight for Your Right (To Party!)", this song was never performed live and it is one of the few songs on the album that are not in the vein of their standard rap songs.

Song structure and lyrics

The song is the shortest on the album, lasting just over 2 minutes long. The song's instrumental is relatively simple, consisting of a drum beat being played over a vibraphone loop, with occasional pauses. The song contains many similarities to the song "Shout" by The Isley Brothers.

Lyrically, the song talks about the narrator (Ad-Rock)'s desire for women. He recalls a experience from two years before with a woman who had an interest in the narrator's band mate MCA. MCA did not share her feelings and permitted the narrator to pursue her romantically. Ad-Rock takes the woman for a walk near a body of water and asks for her hand. The woman rejects his proposal. She moves to a far away location but in the present day the narrator sees her back in town showing interest in his other band mate, Mike D.
