Singö

Coordinates: 60°10′N 18°45′E / 60.167°N 18.750°E / 60.167; 18.750

Singö Is an island located in the north of Stockholm County, close to the border of Uppsala County. The island has around 400 inhabitants and is around 25 km² big. Söderby, Backby, Tranvik, Ellan, Norrvreta and Boda are the villages located on Singö, the closest "big village" is however Grisslehamn on Väddö. In Söderby, there is a small grocery store open from 10:00-18:00 in the week and 10:00-15:00 on weekends and holidays.

LIFE Church UK

LIFE Church UK, formerly the Abundant Life Church, is a large Christian church established and primarily based in Bradford, in the north of England.

The church has additional facilities in Belfast, Leeds and Warsaw and describes itself as "one church, four cities". In 2003 it had an attendance of over 2,000 people; by 2006, the figure had climbed to 2,800.

History

LIFE Church has its roots in the Charismatic Restoration movement of Arthur Wallis. It was founded in 1976 by Bryn Jones, one of the early Restoration/British New Church leaders, by an amalgamation of three small Bradford churches: a charismatic Brethren Assembly based at the Bolton Woods Gospel Hall; an independent charismatic church made up mostly of former Baptists who had been unable to continue in their church because of their charismatic beliefs; and the New Covenant Church, a fellowship originally under the apostolic leadership of G. W. North.

In its early days it met in the Anglican Church House and so was known locally as Church House. Later known as Abundant Life Church for a number of years, in 2012 the name was shortened to LIFE Church, reflecting a move into a season of new leadership and direction.

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 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).
