# Organosilver chemistry

Organosilver chemistry is the study of organometallic compounds containing a carbon to silver chemical bond. The theme is less developed than organocopper chemistry.
The first attempts in organosilver were recorded by Buckton in 1859 and by J. A. Wanklyn & L. Carius in 1861. The synthesis of methyl silver was described by Semerano and Riccoboni Poor thermal stability is reflected in decomposition temperatures of AgMe (-50 °C) versus CuMe (-15 °C) and PhAg (74 °C) vs PhCu (100 °C).

## Alkyl, alkenyl, aryl derivatives

Phenylsilver can be obtained by reaction of silver nitrate with a trialkylphenyllead or diphenylzinc:
    Ph$_2$Zn + AgNO$_3$ → PhAg + "PhZnNO$_3$"
Like all silver complexes, organosilver compounds have coordination numbers ≥2. For example, mesitylsilver is a tetramer with 2-coordinate Ag(I) centers. It is produced by reaction of silver chloride and the Grignard reagent:
    AgCl + (CH$_3$)$_3$C$_6$H$_2$MgBr → 1/4 [(CH$_3$)$_3$C$_6$H$_2$Ag]$_4$ + MgClBr
A variety of organosilver compounds include phosphorus ylides. A simple example is the pentafluorophenylsilver complex of methylenetriphenylphosphorane:
    AgC$_6$F$_5$ + Ph$_3$P=CH$_2$ → Ph$_3$P=CH$_2$−AgC$_6$F$_5$
Alkenylsilver compounds are also more stable than their alkylsilver counterparts. Vinylsilver can be obtained by reaction of silver nitrate with tetravinyllead:
    AgNO$_3$ + (CH$_2$=CH)$_4$Pb → (CH$_2$=CH)Ag + (CH$_2$=CH)$_3$PbNO$_3$

### Fluoroalkyl and fluoroalkenyl derivatives

Following established trends, perfluorinated alkyl and alkenyl derivatives of silver exhibit significant thermal stability. An alkenyl derivatives are generated by the addition of silver fluoride to hexafluorobutyne and tetrafluoroallene.
    AgF + CF$_2$=CF(CF$_3$) → AgCF(CF$_3$)$_2$
Organosilver compounds usually have the oxidation state +1. A notable exception is Ag(CF$_3$)$_4$$^−$.

## Carbene and CO complexes

Silver forms relatively fragile complexes with CO, including [Ag(CO)$_n$]$^+$ (n = 1, 2, 3). The green, planar, paramagnetic Ag(CO)$_3$ is stable at 6–15 K and dimerizes at 25–30 K, probably by forming Ag–Ag bonds. Additionally, the silver carbonyl [Ag(CO)] [B(OTeF$_5$)$_4$] is known.
Silver-NHC complexes are numerous. Some are commonly used to prepare other NHC complexes by displacing labile ligands. For example, the reaction of the bis(NHC)silver(I) complex with bis(acetonitrile)palladium dichloride or chlorido(dimethyl sulfide)gold(I):

## Alkene complexes

Like other heavy d$^{10}$ metal ions, Ag$^+$ has a pronounced affinity for alkenes. The ability of silver to form alkene complexes has long been exploited in the separation of alkenes by "argentation chromatography", which uses a support containing silver salts. Illustrative is [Ag(C$_2$H$_4$)$_3$]$^+$.

## Catalysis

In catalysis silver is active as silver oxide in the Wolff rearrangement. Silver is also present in other carbon-carbon bond skeletal rearrangements such as the quadricyclane to norbornadiene rearrangement, the cubane to cuneane rearrangement and the rearrangement of the cyclobutadiene dimer to cyclooctatetraene.
# Orientering

Orientering was a Norwegian newspaper which was initially published in December 1952 as an alternative voice. It was absorbed into Ny Tid in 1975.
There were many reasons for establishing the newspaper, but the most important was perhaps that it had become very difficult to express viewpoints which were critical of NATO and western capitalism in general.
In 1953 the group from the Labor Party's left wing won, led by Karl Evang. The editor and spokesman for the group was Sigurd Evensmo, with Finn Gustavsen as the co-editor. They also had the support of the Labor Party, such as the party's first Prime Minister, Christopher Hornsrud.
The group's party line was an alternative to the third way, critical of both Moscow and Washington DC. Orientering was therefore opposed to Norwegian membership in NATO, but also gave extensive independence in the imperialism suitable for analysis of international relations. The main current of Norwegian socialism in the 1950s was polarized between Moscow (Communist Party of Norway) and Washington (Norwegian Labour Party). Orientering was almost silent about the Labor Party's newspapers, something which contributed to increasing interest.
The newspaper was characterized by foreign affairs from the beginning. Questions regarding domestic policy grew in large degree after Finn Gustavsen became the editor in 1957. It climaxed with the question of the proposed stockpiling of atomic weaponry in Norway when the national congress in the Labor Party passed a resolution in 1961 allowing for this.
The key people in the inner circle of Orientering considered starting a new party, which would become a reality through the establishment of the Socialist People's Party in 1961. Gustavsen was one of the party's first two representatives to the Norwegian Parliament and relinquished the role of editor to Evang. Orientering became the advocate of the Socialist People's Party; at the same time the newspaper doubled its frequency to releasing a new issue weekly. The Socialist People's Party did not formally take over the newspaper until 1973. The editor from 1965 on was Kjell Cordtsen.
In 1975-1975 assembly meetings were arranged between the parties on the left after the Socialist People's Party's success in the election of 1973. The establishment of the Socialist Left Party was approved and would replace the Socialist People's Party, the Norwegian Communist Party (who later withdrew) and the Democratic Socialists with support from a number of independent socialists.
In connection with this process, Orientering was discontinued and absorbed into the Socialist Left Party's new party newspaper, Ny Tid. From the beginning the circulation was several thousand, but this slowly grew to around 19,000 in 1974, while the last issue reached 16,000. The community surrounding Orientering continued in and around Ny Tid.

# Eastern carrion crow

The eastern carrion crow (Corvus corone orientalis, originally a separate species C.orientalis) is a member of the crow family and a subspecies of the carrion crow. Differences from the nominate subspecies include a larger size, at a length about 500 millimetres (20 in), and more graduated outer tail feathers. The eastern carrion crow is found in Siberia from the Yenisei to Japan, south to Central Asia, Afghanistan, Eastern Iran, Kashmir, Tibet and northern China. They generally lay three to five eggs in trees or buildings. The eggs show no difference from the nominate subspecies.

# Eastleigh–Romsey line

vteEastleigh–Romsey line :
Legend :
The Eastleigh–Romsey line is the railway line from Eastleigh to Romsey in Hampshire, England. At Eastleigh, trains join the South West Main Line for onward travel to Southampton. At Romsey most trains terminate. The line is not electrified and all trains are diesel-powered.

## History

The line, part of the London and South Western Railway, was part of the Bishopstoke (now Eastleigh) to Salisbury line which was authorized by the Salisbury Branch Railway Act 1844 (7 & 8 Vict. c. lxiii) on 4 July 1844. Construction of the line was problematic, as landowners, somewhat unusually, took an obstructive attitude to the railway. The problems were exacerbated by the choice of a small contractor over the more well established and more experienced options in order to save money. In addition, the weather conditions during construction caused earthworks to slip and then freeze. As a result of all these factors, the opening of the line was postponed three times before coal and goods traffic used the line for the first time on 27 January 1847. The line was opened to passenger traffic on 1 March 1847 and was the main route from Salisbury to London from that time until the opening of the direct Salisbury line over a decade later, on 1 May 1857.
Chandler's Ford station was closed to goods traffic on 1 June 1964, and five years later on 5 May 1969, the station was also closed to passengers when regular passenger services were withdrawn. Originally built as a double track, the line was singled on 1 May 1972. The line continued to be used by stone trains from the Mendip area to and from Botley as well as other freight services, as well as weekend diversions of passenger traffic.
A £10 million plan was put forward in 1999 to reopen Southampton Terminus and Northam, which was to have been controlled by East Anglia Railways Train Company, their plans included building a new rail-link using the current remaining track by St. Marys Stadium and as far as the Waterfront, which is now safe guarded by Southampton City Council for future rail links. This would have allowed trains to go from Southampton Waterfront to East Anglia without the need to change at London. It was also hoped it would reduce the traffic around Southampton with a local commuter line linking the Waterfront to Romsey, Halterworth and Chandler's Ford, but the plan failed to come about for reasons unknown.
The line between Eastleigh and Romsey was reopened for passenger traffic in May 2003 with a re-built station at Chandler's Ford.

## Services

Services and stations on this line are operated by South Western Railway. It has an hourly service in each direction which runs a 'figure of six' route from Romsey to Salisbury, running from Romsey via Eastleigh and Southampton before re-visiting Romsey and continuing to Salisbury. The service is currently operated by Class 158 DMUs.

## Route

For much of the route, the line runs close to the Monks Brook; north-east of Chandler's Ford, it crosses the edge of the Trodds Copse Site of Special Scientific Interest.

# Orthotylus beieri

Orthotylus beieri is a species of bug from the Miridae family that can be found in France, Slovenia, and Spain.
# Orion (composition)

Orion is an orchestral composition by the Finnish composer Kaija Saariaho. The work was written in 2002 on a commission from the Cleveland Orchestra. Its world premiere was performed by the Cleveland Orchestra led by conductor Franz Welser-Möst in Cleveland, Ohio, on 23 January 2003. The piece is dedicated to Welser-Möst and the Cleveland Orchestra.

## Composition

Orion has a duration of roughly 22 minutes and is cast in three movements:
* Memento mori
* Winter Sky
* Hunter

### Instrumentation

The work is scored for a large orchestra comprising four flutes (3rd doubling alto flute and piccolo; 4th doubling piccolo), four oboes (4th doubling cor anglais), four clarinets, four bassoons (4th doubling contrabassoon), six horns, four trumpets, three trombones, tuba, timpani (2 sets), four percussionists, two harps, piano, organ, and strings.

## Reception

David Fanning of Gramophone highly praised the piece, declaring that it "deserves to figure on any short list for orchestral masterpiece of the new millennium." In a more lukewarm review, Tim Ashley of The Guardian compared the piece to the composer's cello concerto Notes on Light, remarking that "both are soft-centred works that throb and thrum appealingly, but lack the underlying toughness of Saariaho's best music."
# Orion (film)

Orion is the second feature film by writer/director Asiel Norton. It was released in Canada in 2015, in the UK in 2016, and in the USA in 2017. It stars David Arquette and Lily Cole.

## Plot

# Ormston House

Ormston House is a contemporary art gallery and cultural resource centre, in Limerick, Ireland.

## Background

It was opened in 2011 at 9-10 Patrick Street, Limerick. It was founded after art students occupied the ground floor of the 19th-century building on Patrick Street, and turned it into a gallery and cultural resource space with the support of the Creative Limerick scheme. They have worked with over 300 artists from over 25 countries to deliver over 360 events.
The name Ormston House comes from the first self-service supermarket opened in Limerick city. It was opened by Jack Ormston in 1961 in a Venetian-palazzi style building on the corner of Patrick Street and Ellen Street. The building was later purchased by NAMA and, in 2018, the centre was under threat of closure after New York firm Cerberus Capital Management purchased the Ormston House loan book from the NAMA, and the site was put on the open market in July 2017. In response, over three thousand people signed an online petition to prevent the sale of the building on the open market. In 2021, the ground floor and basement of 9-10 Patrick Street were officially purchased by Limerick Council. Following the purchase, Ormston House was granted a 30 year lease from Limerick Council.
Ormston House is a member of three international networks: Artists' Initiatives Meetings, River Cities Platform, and Trans Europe Halles. In 2018, the group collaborated with EVA International with featured artists and projects include Kevin Gaffney, The Museum of Mythological Water Beasts, Stanzas, THEATREclub, and World Recipe Exchange.
In 2021, their "Women of Limerick" mobile phone app, which placed women of historical importance on a map of Limerick, won the National Heritage Week award for Limerick.

## Notable events and artists

Their Artist-in-Residence programme have included creatives such as theatre practitioner Ann Blake, artist Ciara Barker, artist Mary Conroy, artist Ceara Conway, artist Isolde Donohoe, musician Mícheál Keating, writer William Keohane, artist Niamh Porter, theatre practitioner Joanne Ryan, and historian Sharon Slater.

# Ecce Homo (Daumier)

Ecce Homo is an unfinished oil-on-canvas painting by the French painter and caricaturist Honoré Daumier, created in 1850. It is in the collection of the Museum Folkwang in Essen, Germany.

## Description

The painting, executed in undertones of various shades of brown, depicts a scene in the Good Friday trial of Jesus when Christ is presented to the mob as a figure of ridicule by Pontius Pilate with the words "Ecce Homo", translated in the Bible as "Behold the Man", but more appropriately as an accusatory "Look at this man". The viewer is situated in the crowd in a position where he can observe Christ standing still and resolute, silhouetted against a sacred light, and asked to decide whether to sympathise with Him or with His tormentors.
The work is one of only a few that Daumier undertook on religious subjects, as distinct from his several depictions of contemporary French social inequalities.

## Reception

James Romaine stated that this is "one of the most haunting images of Jesus Christ produced in nineteenth-century France. Part of this painting’s success, as an example of the Realist method applied to a biblical narrative, is the direct engagement that the work of art establishes between the subject and the viewer./ (...) As a subject highlighting the corruption of a justice system, the trial of Christ iconographically fits within a recurring theme in Daumier’s art. The mob gathered to taunt Christ recalls contemporary episodes of political unrest frequently evoked in nineteenth-century Realist art."
The painting was included by French writer Michel Butor in his book selecting 105 decisive works of Western painting.
