Clontarf, Dublin
Clontarf () is a largely affluent coastal suburb on the Northside of Dublin in the city's Dublin 3 postal district. Historically there were two centres of population, one on the coast towards the city, and the fishing village of Clontarf Sheds, further north on the coast at what is now Vernon Avenue. Clontarf has a range of commercial facilities in several locations, mainly centred on Vernon Avenue. It adjoins Fairview, Marino, Killester and Raheny. Clontarf is in the jurisdiction of Dublin City Council. Clontarf was a core site of the Battle of Clontarf in 1014, in which Brian Boru, High King of Ireland, defeated the Vikings of Dublin and their allies, the Irish of Leinster. This battle, which extended over a wide area, from modern Ballybough to Kilbarrack, at least, is seen as marking an end to the Irish-Viking Wars. Etymology The name ''Cluain Tarbh'' means "meadow of the bull", ''cluain'' being "meadow" and ''tarbh'' meaning "bull" in Irish. Geography Clontarf is on ...

First-class Cricket
First-class cricket, along with List A cricket and Twenty20 cricket, is one of the highest-standard forms of cricket. A first-class match is one of three or more days' scheduled duration between two sides of eleven players each and is officially adjudged to be worthy of the status by virtue of the standard of the competing teams. Matches must allow for the teams to play two innings each, although in practice a team might play only one innings or none at all. The etymology of "first-class cricket" is unknown, but it was used loosely before it acquired official status in 1895, following a meeting of leading English clubs. At a meeting of the Imperial Cricket Conference (ICC) in 1947, it was formally defined on a global basis. A significant omission of the ICC ruling was any attempt to define first-class cricket retrospectively. That has left historians, and especially statisticians, with the problem of how to categorise earlier matches, especially those played in Great Britain be ...

Batsman
In cricket, batting is the act or skill of hitting the ball with a bat to score runs and prevent the loss of one's wicket. Any player who is currently batting is, since September 2021, officially referred to as a batter (historically, the terms "batsman" and "batswoman" were used), regardless of whether batting is their particular area of expertise. Batters have to adapt to various conditions when playing on different cricket pitches, especially in different countries - therefore, as well as having outstanding physical batting skills, top-level batters will have quick reflexes, excellent decision-making and be good strategists. During an innings two members of the batting side are on the pitch at any time: the one facing the current delivery from the bowler is called the striker, while the other is the non-striker. When a batter is out, he is replaced by a team-mate. This continues until the end of the innings, which in most cases is when 10 of the team members are out, w ...

Kainji Dam
Kainji Dam is a dam across the Niger River in Niger State of Central Nigeria. Construction of the dam was carried out by Impregilo (a consortium of Italian Civil Engineering Contractors) to designs by Joint Consultants, Balfour Beatty and Nedeco, and began in 1964 to be completed in 1968. The total cost was estimated at US$209 million (equivalent to about US$ billion in dollars), with one-quarter of this amount used to resettle people displaced by the construction of the dam and its reservoir, Kainji Lake. Dimensions Kainji Dam extends for about , including its saddle dam, which closes off a tributary valley. The primary section across the outflow to the Niger is . Most of the structure is made from earth, but the centre section, housing the hydroelectric turbines, was built from concrete. This section is high. Kanji Dam is one of the longest dams in the world. Power station The dam was designed to have a generating capacity of ; however, only 8 of its 12 turbines have been ins ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Churchill Barriers
The Churchill Barriers are four causeways in the Orkney islands with a total length of . They link the Orkney Mainland in the north to the island of South Ronaldsay via Burray and the two smaller islands of Lamb Holm and Glimps Holm. The barriers were built between May 1940 and September 1944, primarily as naval defences to protect the anchorage at Scapa Flow, but since 12 May 1945, serve as road links between the islands. The two southern barriers, Glimps Holm to Burray and Burray to South Ronaldsay, are Category A listed. History On 14 October 1939, the Royal Navy battleship HMS ''Royal Oak'' was sunk at her moorings within the natural harbour of Scapa Flow, by the under the command of Günther Prien. ''U-47'' had entered Scapa Flow through Holm Sound, one of several eastern entrances to Scapa Flow. The eastern passages were protected by measures including sunken block ships, booms and anti-submarine nets, but ''U-47'' entered at night at high tide by navigating be ...

London Passenger Transport Board
The London Passenger Transport Board was the organisation responsible for local public transport in London and its environs from 1933 to 1948. In common with all London transport authorities from 1933 to 2000, the public name and brand was London Transport. History The London Passenger Transport Board (LPTB) was established pursuant to the London Passenger Transport Act 1933 enacted on 13 April 1933. The bill had been introduced by Herbert Morrison, who was Transport Minister in the Labour Government until 1931. Because the legislation was a hybrid bill it had been possible to allow it to 'roll over' into the new parliament under the incoming National Government. The new government, although dominated by Conservatives, decided to continue with the bill, with no serious changes, despite its extensive transfer of private undertakings into the public sector. On 1 July 1933, the LPTB came into being, covering the "London Passenger Transport Area". The LPTB's financial structure ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Piccadilly Line
The Piccadilly line is a deep-level London Underground line running from the north to the west of London. It has two branches, which split at Acton Town, and serves 53 stations. The line serves Heathrow Airport, and some of its stations are near tourist attractions such as Piccadilly Circus and Buckingham Palace. The District and Metropolitan lines share some sections of track with the Piccadilly line.

Mott, Hay And Anderson
Mott, Hay and Anderson (MHA) was a successful 20th century firm of consulting civil engineers based in the United Kingdom. The company traded until 1989, when it merged with Sir M MacDonald & Partners to form '' Mott MacDonald''. History Early years The company was founded as a private partnership between Basil Mott and David Hay on 30 July 1902. Prior to forming the partnership both had spent time building London tube railways and Hay had worked on the Blackwall Tunnel, so it was no surprise that they concentrated on heavy civil engineering projects such as bridges, tunnels, railways and docks.

Mott and Hay employed a youn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tees Newport Bridge
The Tees Newport Bridge is a vertical-lift bridge spanning the River Tees a short distance upriver from Tees Transporter Bridge, linking Middlesbrough with the borough of Stockton-on-Tees, Northern England. It no longer lifts, but still acts as a road bridge in its permanently down position. Design Designed by Mott, Hay and Anderson and built by local company Dorman Long, who have also been responsible for such structures as the Tyne Bridge and Sydney Harbour Bridge, it was the first large vertical-lift bridge in Britain. Constructed around twin lifting towers, the bridge span, weighing 2,700 tonnes, could be lifted by the use of two 325 H.P. electric motors at per minute to a maximum height of . In the event of motor failure a standby 450 H.P. petrol engine could be employed to move the bridge, but should both systems fail it was possible to raise or lower the span manually using a winch mechanism. It was estimated in 1963 by Mr R. Batty, long time Bridge Ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
