The Sigma is an experimental glider developed in Britain from 1966 by a team led by Nicholas Goodhart. After disappointing performance during flight testing the Sigma was passed on to a Canadian group which carried out modifications, making the Sigma more competitive.
Designed to compete in the 1970 World Championships, the team aimed to develop a wing that would climb well through a high lift coefficient and a large wing area, but equally had the "maximum possible reduction of area for cruise at low lift coefficients". At the same time for the minimum possible drag they aimed for "extensive" laminar flow. To achieve this they employed flaps that would alter both wing area and wing camber. Based on analysis of the nature of thermals encountered in cross-country flying, they reasoned that by having a slow turning circle, their sailplane could stay close to the central (and strongest) part of the thermal and gain maximum benefit.
Its unusual feature is its ability to vary its wing area using Fowler flaps. It had been tried before by the Hannover Akaflieg in 1938 with their AFH-4, the South African Beatty-Johl BJ-2 Assegai and the SZD Zefir gliders.
Sigma in cosmology was a property of galaxies used when trying to work out the mystery of galaxies and their supermassive black holes.
In the late 1990s the NUKER experts had made observations with a spectroscope of two galaxies, one of an active galaxy with an active galactic nucleus called NGC10-68 and a dormant galaxy next door to us named Andromeda.
The observations are shown. The light from the centre in Andromeda galaxy was distorted proving the existence of super-massive black holes.
Other observations proved most galaxies had a similar centre whether it be active or dormant.
They then realised that the black holes must have something to do with a galaxy's formation, so they turned to something they thought was useless: the speed of the stars around the edge of the galaxy. This was Sigma, the speed of the stars at the edge of the galaxy supposedly unaffected by the mass of the black hole at the centre.
The NUKER team calculated the sigma of several stars in different galaxies and the mass of the black hole at the (nucleus) centre. They expected no correlation what so ever. But when plotting their results on a Scatter diagram and drawing a line of best fit they ended up with a positive correlation. It appeared that the heavier the black hole at the centre was the faster the stars within the galaxy travelled.
Sigma is an English drum and bass duo consisting of Cameron Edwards and Joe Lenzie. They met at Leeds University at drum and bass nights. Their 2010 collaboration with DJ Fresh, "Lassitude", peaked at number 98 on the UK Singles Chart. Their single "Nobody to Love" topped the UK Singles Chart, becoming their first UK number one. Follow-up single "Changing", featuring Paloma Faith, also got to number one.
Lenzie and Edwards met in 2006 at Leeds University; Cameron was working in local record store Tribe Records and with Echo Location's Obi running local night Event Horizon, while Lenzie was DJing hip-hop and warming up Event Horizon for such acts as Rahzel and Grandmaster Flash. Once they had finished in Leeds, they relocated to London and became a three-piece with Edwards' school friend Ben Mauerhoff, being signed under DJ Fresh's Breakbeat Kaos. After a while, long distances took their toll – Edwards and Mauerhoff were based in Surrey, whereas Lenzie was based in Harpenden, Hertfordshire and they couldn't get three people into the Harpenden studio – and Mauerhoff left. In December 2008 they formed their own record label, Life Recordings (so called because, according to Lenzie, the industry demanded that it be their life). Its inaugural release was a VIP mix of their early Bingo Beats single "El Presidente".
A splinter (known as sliver in Canada) is a fragment of a larger object (especially wood), or a foreign body that penetrates or is purposely injected into a body. The foreign body must be lodged inside tissue to be considered a splinter. Splinters may cause initial pain through ripping of flesh and muscle, infection through bacteria on the foreign object, and severe internal damage through migration to vital organs or bone over time.
Splinters commonly consist of wood, but there are many other types. According to the American Academy of Family Physicians (AAFP), common types of splinters are glass, plastic, metal, and spines of animals.
Generally, a splinter causes an initial feeling of pain as the sharp object makes its initial penetration through the body. Through this penetration, the object cuts through the cutaneous layer of the skin, and settles in the subcutaneous layer of the skin, and can even penetrate further down, breaking the sub-cutaneous layer, settling in muscle tissue, or even the bone. Some splinters will remain in place, but most will continue to migrate through the body, further damaging their surroundings.
Splinter is a 2006 American police-action film set in Los Angeles directed by Michael D. Olmos and starring Tom Sizemore, Noel Gugliemi and Edward James Olmos.
The movie's concept originated with writer and actor Enrique Almeida, who portrays the film's lead character. Noel Gugliemi, who starred as the lead character's brother, stated that the filmmakers wanted to create "a Mexican version of Friday, a Mexican version of Menace II Society." The film grossed $12,918 in United States theaters.
Dreamer (Enrique Almeida) is being questioned by Detective Gramm (Resmine Atis). We flash back to Dreamer and Shaggy sitting in a car when another car pulls up and does a drive-by shooting. The drive by kills Shaggy and the bullet passes through and into Dreamers head.
A girl is poking through a pile of trash and finds the bodies of the men who performed the drive by. It is revealed that Shaggy of the Greenville gang had been going with Vanessa who was with Trigger (Hector Atreyu Ruiz ) of the opposing gang. Vanessa says that the night of the drive-by that Trigger was hiding something. Another shooting leaves two more dead. Detectives Cunningham (Tom Sizemore) and Gramm question two men whom say that the killings were done by members of Greenville. Vanessa gives Dreamer Triggers gun, Dreamer then calls Gramm to have her meet him in the alley where he gives her three spent bullets and casings from the gun.
Master Splinter, or simply Splinter, is a fictional character from the Teenage Mutant Ninja Turtles comics and all related media.
Splinter has three origin stories, and which one is used depends on the medium. In the original version of the tale, he was Hamato Yoshi's pet, in other versions he is Hamato Yoshi himself, but always mutated into the form of a man-sized rat. In another he is a mutant rat with no connection to Yoshi.
In both the original comics and the live-action movies, Splinter was the pet rat of a ninja named Hamato Yoshi in Japan. Intelligent for his species, Splinter was able to learn his master's art by mimicking his movements while he practiced. Yoshi became embroiled in a dispute with a fellow ninja by the name of Oroku Saki, and he was eventually murdered by Nagi's brother Oroku Saki who sought revenge for his brothers death. However, in the 1990 film and 2003 TV series Nagi was removed entirely. Additionally in the 1990 film, Splinter escapes from his cage during the murder, and attackes Saki, clawing at his face. Saki in turn sliced his ear off. It is suggested this mutilation is the reason Saki took the Shredder disguise to hide the scars. While in the 2003 TMNT cartoon it was Hun's face who Splinter clawed.
