Pressure prism

Hydrostatic pressure is the pressure exerted by a fluid at rest; for example on the sides of a swimming pool, glass of water or the bottom of the ocean. Its value at a given location within the fluid is the product the fluid density (ρ), the depth (d) and the forces applied by gravity (g), plus any background pressures, such as Atmospheric pressure.

Hydrostatic Pressure on surfaces surrounding (or within) fluid volumes can be represented by the Pressure Prism, which is a useful visualization technique.

Hydrostatic pressure increases linearly with depth. Generally it can be expressed by the relationship;

where pressure at top is zero and at bottom is ρgH . Where H is total depth of fluid volume.

Variation of pressure along depth can be seen in figure 1.

Further, the centre of pressure on the wall can be calculated by the formula

by which we get the height of COP for a plane surface as H/3 from bottom which is also shown in figure 2.

If we have two different kind of fluids in our volume then the slope of our pressure prism will not be constant over the depth and rather be somewhat like shown in figure 3.

He was the most popular British R&B singer-songwriter of the early to mid-1980s. After scoring his first four UK Top 20 successes, seven years passed before he accumulated a series of transatlantic successes, including three U.S. number ones. In 1985, Ocean won the Grammy Award for Best Male R&B Vocal Performance for his worldwide hit, "Caribbean Queen", and in 1987 was nominated for the Brit Award for Best British Male Artist.

In 2002, the University of Westminster, London, awarded Ocean an honorary doctorate of music. In 2010, Ocean was presented with the Lifetime Achievement Award at the MOBO Awards. On 29 July 2011, Ocean became a Companion of the Liverpool Institute for Performing Arts, presented to him by Sir Paul McCartney. He is a member of the Rastafari movement.

List of Humanx Commonwealth planets

This is a list of the fictional planets in the Humanx Commonwealth series of novels by Alan Dean Foster.

Alaspin

Alaspin has large jungles surrounded by equally large savannas and river plains; its only notable celestial feature is two moons.

Currently the planet has no sentient race; the native race died out, possibly by racial suicide, over 75,000 years ago leaving behind hundreds of ancient, abandoned cities that have proved a source of fascination to modern xeno-archaeologists.

A variety of lifeforms currently live on Alaspin, most notably the Alaspinian minidrag.

Annubis

Annubis is most notable for the fictional Hyperion forests from which the fictional drug bloodhype is manufactured. In an attempt to eradicate the highly addictive and deadly drug, the trees were burned in 545 A.A. and are thought to be completely destroyed.

The planet first appeared in the novel Bloodhype.

Blasusarr

Blasusarr is the homeworld of the AAnn race and is often called the Imperial Home World. Climate is dry and hot, largely desert, the preferred atmospheric conditions of the AAnn. Beyond this, little is known about Blasusarr other than the fact that it is very well-protected by a detection and space defense network. Its capital city, also the capital of the AAnn Empire, is Krrassin.

Rash (film)

Rash, written RASH, is a 2005 Australian documentary film, directed by Nicholas Hansen. Its subject is contemporary urban Australia and the artists who are making it a host for illegal street art. With the tagline 'Scratch it and it spreads', Rash explores the cultural value of unsanctioned public art and the ways that street art and graffiti contribute to public dialogue.

Directed by Nicholas Hansen and Mutiny Media, Rash was three years in the making and includes interviews with many of Melbourne’s inspired street art and graffiti artists as well as visitors who came to Melbourne and leave their mark. Rash is the first feature-length documentary in Australia to focus on the new art form of street art.

Filming began in 2002 on this documentary, which conveys the commitment, ideals and beliefs demonstrated in Melbourne street art. Artists use a variety of approaches including bill posters, stencils, and performance art put the artwork right in the public eye.

The film was made in the lead up to the Melbourne 2006 Commonwealth Games. Before the games local councils were juggling the need to present a clean and safe city for visitors against the enthusiastic activities of street and graffiti artists. A similar response was later observed in the lead up to the London 2012 Summer Olympics

Yoshida Brothers

The Yoshida Brothers (吉田兄弟, Yoshida Kyōdai) are Japanese musicians who have released several albums on the Domo Records label.

The two brothers are performers of the traditional Japanese music style of Tsugaru-jamisen which originated in northern Japan. They debuted in 1999 in Japan as a duo playing the shamisen. Their first album sold over 100,000 copies and made them minor celebrities in Japan, a fact that surprised the Yoshida Brothers themselves. They have since attracted an international audience.

Their music has been a fusion of the rapid and percussive Tsugaru-jamisen style along with Western and other regional musical influences. In addition to performing songs that are only on the shamisen, they also use instruments such as drums and synthesizers.

The commercials for the Nintendo's Wii video game console that began airing in North America in November 2006 featured the Yoshida Brothers song "Kodo (Inside the Sun Remix)".

Members

Ryōichirō Yoshida (吉田 良一郎, Yoshida Ryōichirō, born 26 July 1977) and Kenichi Yoshida (吉田 健一, Yoshida Ken'ichi, born 16 December 1979) were born in Noboribetsu in Hokkaido, Japan. The two brothers have played the shamisen from a very young age. They both began to study and play the shamisen from five years of age under Koka Adachi, learning the Minyō-shamisen style; from about 1989 they studied the Tsugaru-jamisen style under Takashi Sasaki.
