Purple

Purple is defined as a deep, rich shade between crimson and violet, or, more broadly, as a range of hues of color between blue and red, or as a dark color that is a blend of red and blue. According to surveys In Europe and the U.S., purple is the color most often associated with royalty, magic, mystery and piety. When combined with pink, it is associated with eroticism, femininity and seduction.

Purple was the color worn by Roman magistrates; it became the imperial color worn by the rulers of the Byzantine Empire and the Holy Roman Empire, and later by Roman Catholic bishops. Similarly in Japan, the color is traditionally associated with the Emperor and aristocracy.

Purple and violet are similar, though purple is closer to red. In optics, there is an important difference; purple is a composite color made by combining red and blue, while violet is a spectral color, with its own wavelength on the visible spectrum of light.

Etymology and definitions

The word 'purple' comes from the Old English word purpul which derives from the Latin purpura, in turn from the Greek πορφύρα (porphura), name of the Tyrian purple dye manufactured in classical antiquity from a mucus secreted by the spiny dye-murex snail.

Film (band)

Film was a Yugoslav rock group founded in 1978 in Zagreb. Film was one of the most popular rock groups of the former Yugoslav new wave in the late 1970s to early 1980s.

History

New wave years (1979-1981)

During 1977 and 1978, bassist Marino Pelajić, guitarist Mladen Jurčić, and drummer Branko Hromatko were Azra members when Branimir "Johnny" Štulić brought Jura Stublić as the new vocalist. Stublić was to become Aerodrom member, but due to his deep vocals it never happened. The lineup functioned for a few months only and after a quarrel with Štulić, on early 1979, Pelajić, Jurčić, Hromatko and Stublić formed the band Šporko Šalaporko i Negove Žaluzine, naming the band after a story from the "Polet" youth magazine, which was soon after renamed to Film. The memories of the Azra lineup later inspired Štulić to write the song "Roll over Jura" released on Filigranski pločnici in 1982.

Saxophonist Jurij Novoselić, who at the time had worked under the pseudonym Kuzma Videosex, joined the band, inspiring others to use pseudonym instead of their original names: vocalist Stublić became Jura Jupiter, bassist Pelajić became Mario Baraccuda and guitarist Jurčić became Max Wilson. Before joining the band, Stublić did not have much experience as a vocalist, however, since his father had been an opera singer, he often visited the theatre and opera, and at the age of 13, he started playing the guitar, earning money as a street performer at seaside resorts.

Film (film)

Film is a 1965 film written by Samuel Beckett, his only screenplay. It was commissioned by Barney Rosset of Grove Press. Writing began on 5 April 1963 with a first draft completed within four days. A second draft was produced by 22 May and a forty-leaf shooting script followed thereafter. It was filmed in New York in July 1964.

Beckett’s original choice for the lead – referred to only as “O” – was Charlie Chaplin, but his script never reached him. Both Beckett and the director Alan Schneider were interested in Zero Mostel and Jack MacGowran. However, the former was unavailable and the latter, who accepted at first, became unavailable due to his role in a "Hollywood epic." Beckett then suggested Buster Keaton. Schneider promptly flew to Los Angeles and persuaded Keaton to accept the role along with "a handsome fee for less than three weeks' work."James Karen, who was to have a small part in the film, also encouraged Schneider to contact Keaton.

The filmed version differs from Beckett's original script but with his approval since he was on set all the time, this being his only visit to the United States. The script printed in Collected Shorter Plays of Samuel Beckett (Faber and Faber, 1984) states:

Lubrication theory

In fluid dynamics, lubrication theory describes the flow of fluids (liquids or gases) in a geometry in which one dimension is significantly smaller than the others. An example is the flow above air hockey tables, where the thickness of the air layer beneath the puck is much smaller than the dimensions of the puck itself.

Internal flows are those where the fluid is fully bounded. Internal flow lubrication theory has many industrial applications because of its role in the design of fluid bearings. Here a key goal of lubrication theory is to determine the pressure distribution in the fluid volume, and hence the forces on the bearing components. The working fluid in this case is often termed a lubricant.

Free film lubrication theory is concerned with the case in which one of the surfaces containing the fluid is a free surface. In that case the position of the free surface is itself unknown, and one goal of lubrication theory is then to determine this. Surface tension may then be significant, or even dominant. Issues of wetting and dewetting then arise. For very thin films (thickness less than one micrometre), additional intermolecular forces, such as Van der Waals forces or disjoining forces, may become significant.
