UNISON

UNISON is the second largest trade union in the United Kingdom with almost 1.3 million members.

The union was formed in 1993 when three public sector trade unions, the National and Local Government Officers Association (NALGO), the National Union of Public Employees (NUPE) and the Confederation of Health Service Employees (COHSE) merged.

UNISON's current general secretary is Dave Prentis. He was elected on 28 February 2000 and took up the post on 1 January 2001, succeeding Rodney Bickerstaffe who had held the post for five years.

Members and organisation

Members of UNISON are typically from industries within the public sector and generally cover both full-time and part-time support and administrative staff. The majority of people joining UNISON would be workers within areas such as local government, education, the National Health Service Registered Nurses, NHS Managers & Clinical Support Workers. The union also admits ancillary staff such as Health Care Assistants and Assistant Practitioners, including Allied Health Professionals. Probation services, police services, utilities (such as gas, electricity and water), and transport. These 'Service Groups' all have their own national and regional democratic structures within UNISON's constitution.

Unison (video)

Unison is Celine Dion's first home video, released on VHS on July 2, 1991. It includes the music videos from her English debut album Unison.

This collection features never before used version of "Calling You," previously unreleased version of Dion's breakthrough hit "Where Does My Heart Beat Now" (Canadian black-and-white version mixed with the U.S. performance version), plus exclusive interviews with Dion at her home.

Three videos: "Délivre-moi," "Have a Heart," and "Calling You" were filmed during the Unison Tour at the Winter Garden Theatre in Toronto, Canada, and later shown in the 1991 MusiMax TV special.

In the United States, the U.S. version of "(If There Was) Any Other Way" from 1991 was included; in Canada, the Canadian version from 1990. This VHS was made in both English and in French. The two contain similar interviews conducted in both languages.

Unison home video was certified Gold in Canada.

Unison (file synchronizer)

Unison is a file synchronization program. It is used for synchronizing files between two directories, either on one computer, or between a computer and another storage device (e.g. another computer, or a removable disc). It runs on Unix-like operating systems (including Linux, Mac OS X, Android, and Solaris) and Windows.

Details

Unison allows the same version of files to be maintained on multiple computing devices. In other words, when two devices are synchronized, the user can be sure that the most current version of a file is available on both devices, regardless of where it was last modified.

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 (cosmology)

Sigma in cosmology was a property of galaxies used when trying to work out the mystery of galaxies and their supermassive black holes.

History

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.

Usage In Cosmology

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 (duo)

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.

Career

Formation

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".
