Operation Sigma Sigma
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.
Design and development
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 baryon
The Sigma baryons are a family of subatomic hadron particles which have a +2, +1 or −1 elementary charge or are neutral. They are baryons containing three quarks: two up and/or down quarks, and one third quark, which can be either a strange (symbols Σ+, Σ0, Σ−), a charm (symbols Σ++
c, Σ+
c, Σ0
c), a bottom (symbols Σ+
b, Σ0
b, Σ−
b) or a top (symbols Σ++
t, Σ+
t, Σ0
t) quark. However, the top Sigmas are not expected to be observed as the Standard Model predicts the mean lifetime of top quarks to be roughly 6975500000000000000♠5×10−25 s. This is about 20 times shorter than the timescale for strong interactions, and therefore it does not form hadrons.
List
The symbols encountered in these lists are: I (isospin), J (total angular momentum), P (parity), u (up quark), d (down quark), s (strange quark), c (charm quark), t (top quark), b (bottom quark), Q (charge), B (baryon number), S (strangeness), C (charmness), B′ (bottomness), T (topness), as well as other subatomic particles (hover for name).
Six Sigma
Six Sigma is a set of techniques and tools for process improvement. It was introduced by engineer Bill Smith while working at Motorola in 1986.Jack Welch made it central to his business strategy at General Electric in 1995. Today, it is used in many industrial sectors.
Six Sigma seeks to improve the quality of the output of a process by identifying and removing the causes of defects and minimizing variability in manufacturing and business processes. It uses a set of quality management methods, mainly empirical, statistical methods, and creates a special infrastructure of people within the organization, who are experts in these methods. Each Six Sigma project carried out within an organization follows a defined sequence of steps and has specific value targets, for example: reduce process cycle time, reduce pollution, reduce costs, increase customer satisfaction, and increase profits.
The term Six Sigma originated from terminology associated with statistical modeling of manufacturing processes. The maturity of a manufacturing process can be described by a sigma rating indicating its yield or the percentage of defect-free products it creates. A six sigma process is one in which 99.99966% of all opportunities to produce some feature of a part are statistically expected to be free of defects (3.4 defective features per million opportunities). Motorola set a goal of "six sigma" for all of its manufacturing operations, and this goal became a by-word for the management and engineering practices used to achieve it.
Nasty (Pixie Lott song)
"Nasty" is a song by English recording artist Pixie Lott from her self-titled third studio album (2014). It was released on 7 March 2014 as the album's lead single by Mercury Records. The accompanying music video was filmed in November 2013 and directed by Bryan Barber. A second version featured British band The Vamps was released in the same day only in United Kingdom and Ireland.
"Nasty" was previously recorded by American singer Christina Aguilera in collaboration with CeeLo Green for inclusion on the soundtrack to the 2010 film Burlesque, which stars Aguilera and Cher, but it was ultimately scrapped from the official track listing due to legal issues concerning sample clearance.
Background
"Nasty" was previously recorded by several artists, including Christina Aguilera, who recorded the song as a duet with CeeLo Green for her debut film project Burlesque (2010). However, their version did not make the final track listing due to legal issues concerning sample clearance. After Lott's legal team managed to clear all of the song's samples, the singer recorded her own version of the song and released it as the first single from her self-titled third studio album. In an interview with Metro, Lott explained, "A few other singers had recorded it and Christina was one of them so everyone wanted this song. When I heard other singers had done it I thought 'I need to get this!' It was a difficult song to get because there are so many old-school samples on it, like James Brown, that are hard to clear copyright on. But I got it and now it is my new single."
Nasty (Janet Jackson song)
"Nasty" is the second single from Janet Jackson's third studio album, Control (1986). Released in 1986, the single peaked at number three on Billboard Hot 100 and number one on the Hot R&B/Hip-Hop Songs, and remains one of Jackson's signature songs. The line "My first name ain't baby, it's Janet – Miss Jackson if you're nasty" is a well-known catchphrase and has frequently been used in pop culture in various forms.
The song won for Favorite Soul/R&B Single at the 1987 American Music Awards. It ranked number 30 on VH1's 100 Best Songs of the Past 25 Years, number 45 on VH1's 100 Greatest Songs of the 80s, and number 79 on Rolling Stone's 100 Greatest Pop Songs. It has been included in each of Jackson's greatest hits albums Design of a Decade: 1986–1996 (1995), Number Ones (2009) and Icon: Number Ones (2010).
Britney Spears covered "Nasty", along with "Black Cat" during her ...Baby One More Time Tour and has paid homage to the song and video multiple times. The song appears in video games DJ Hero 2, Dance Central 2 (as DLC), and Lips (as DLC).
Nasty (film)
Nasty (Czech: Nestyda), also translated as Shameless, is a 2008 Czech comedy film directed by Jan Hřebejk. Following their collaborations on A Novel for Women and The Holiday Makers, Czech filmmaker Hřebejk and author Michal Viewegh reunited for Nasty, a comic romp based on Viewegh’s bestselling Tales of Marriage and Sex.
Plot
Oskar (Jiří Macháček), a popular TV weather forecaster, suddenly wakes up to an altered sense of identity: rather than belonging to easygoing wife Zuzana (a bewildered Simona Babčáková), he feels he ought to belong to the whole wide world – hence the national embarrassment. His first entanglement is with babysitter Kocicka (Eva Kerekéšová), a lean teenybopper who's more attached to her pet turtle than her older lover – at least until he accidentally smothers it in the dryer. Next in line is mature pop icon Nora (Emília Vášáryová), who's about to teach him a thing or two about freedom: the more people you let in, the more alone you end up feeling.
Cast
Loud (band)
Loud were a hard rock band with alternative rock, gothic rock and heavy metal influences, formed in Bradford, England in 1989.
The band was founded by guitarist Chris McLaughlin, following his stint in New Model Army. Former Excalibur bassist Martin Hawthorn, second guitarist Colin Clarkson and drummer Ricky Howard (formerly of Happiness AD) completed the line-up.
History
The group's debut album, released in 1990 on China Records, was called D Generation. It was co-produced by J. Martin Rex and Jaz Coleman of Killing Joke. Kerrang! magazine voted it one of their twenty best albums of 1990.
The band subsequently went out on the road in late 1990, playing some live dates as support to former Duran Duran guitarist Andy Taylor. These were followed by support slots with Killing Joke at the London Astoria on 31 January 1991 and The Godfathers at the Town & Country Club on 21 March 1991, and by their own headline tour of the UK during the Spring.
In July 1991, the band played at the second annual Cumbria Rock Festival at Derwent Park stadium in Workington.
