A propeller is a type of fan that transmits power by converting rotational motion into thrust. A pressure difference is produced between the forward and rear surfaces of the airfoil-shaped blade, and a fluid (such as air or water) is accelerated behind the blade. Propeller dynamics, like those of aircraft wings, can be modelled by either or both Bernoulli's principle and Newton's third law. A marine propeller of this type is sometimes colloquially known as a screw propeller or screw, however there is a different class of propellers known as cycloidal propellers - they are characterized by the higher propulsive efficiency averaging 0.72 compared to the screw propellers average of 0.6 and the ability to throw thrust in any direction at any time. Their disadvantages are higher mechanical complexity and higher cost.
The principle employed in using a screw propeller is used in sculling. It is part of the skill of propelling a Venetian gondola but was used in a less refined way in other parts of Europe and probably elsewhere. For example, propelling a canoe with a single paddle using a "pitch stroke" or side slipping a canoe with a "scull" involves a similar technique. In China, sculling, called "lu", was also used by the 3rd century AD.
The album's lead single was "With My Heart in Your Hands".
Dog's Eye View founder and vocalist Peter Stuart had left the band to pursue solo projects following their 1997 release, Daisy. Stuart, who had been a solo performer prior to forming Dog's Eye View, has stated that the idea of his making a solo album originally came from the group's record label, Columbia Records:
His first solo album was originally slated to be called Songs About You. Stuart began recording the album for Columbia, which had released the first two Dog's Eye View albums, Happy Nowhere and Daisy. Early production and recording were completed in Los Angeles. However, Stuart soon became disenchanted with Columbia executives, citing a lack of support for the album and other creative differences. He voluntarily severed ties with Columbia, and left the label with the rights to his forthcoming solo album.
Propeller TV is broadcast on SKY Channel 189 and is the premium channel for the UK-China community.
Recently Propeller TV was launched on the CIBN platform (China International Broadcasting Network) in China and continues to broadcast across a UK higher education television network covering 230,000 students.
The channel was created with UK government investment and began broadcasting in 2005. In 2009 Propeller TV was bought by the Xiking Group, Beijing.
Propeller TV relaunched during April 2013 with a new weekly schedule and content produced in both the UK and China.
It was run by the Image Channel Company Ltd, a subsidiary of the Grimsby Institute in the United Kingdom until it was acquired in June 2009 by the Xiking Group, after six months of talks. There are plans to overhaul the channel and produce programmes promoting Chinese culture, brands and people, with some possibly broadcast in Chinese.
Doom is a series of first-person shootervideo games developed by id Software. The series focuses on the exploits of an unnamed space marine operating under the auspices of Union Aerospace Corporation (UAC), who fights hordes of demons and the undead in order to survive.
Doom is considered to be one of the pioneering first-person shooter games, introducing to IBM-compatible computers features such as 3D graphics, third dimension spatiality, networked multiplayer gameplay, and support for player-created modifications with the Doom WAD format. Since the release of Doom in 1993, the series has spawned numerous sequels, expansion packs, and a film.
Since its debut, over 10 million copies of games in the Doom series have been sold.
