Spire Of Dublin
The Spire of Dublin, alternatively titled the Monument of Light ( ga, An Túr Solais), is a large, stainless steel, pin-like monument in height, located on the site of the former Nelson's Pillar (and prior to that a statue of William Blakeney) on O'Connell Street, the main thoroughfare of Dublin, Ireland. History Following the bombing of Nelson's Pillar by former IRA members in 1966, and subsequent controlled demolition six days later of what was left, the site remained vacant for years as no decision could be reached on a suitable replacement. Eventually, the '' Anna Livia'' monument was installed on the site to celebrate the 1988 Dublin Millennium celebrations. In 1998, as part of a planned multi-million euro re-development of O'Connell Street (as well as a memorial to the upcoming millennium and the aspirations of Ireland in the midst of its Celtic Tiger economic boom), a competition was launched to find a replacement for Nelson's Pillar. O'Connell Street had been in dec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
O'Connell Street
O'Connell Street () is a street in the centre of Dublin, Republic of Ireland, Ireland, running north from the River Liffey. It connects the O'Connell Bridge to the south with Parnell Street to the north and is roughly split into two sections bisected by Henry Street, Dublin, Henry Street. The Luas tram system runs along the street. During the 17th century, it was a narrow street known as Drogheda Street, named after Henry Moore, Earl of Drogheda. It was widened in the late 18th century by the Wide Streets Commission and renamed Sackville Street (''Sráid Saicfil'') after Lionel Sackville, 1st Duke of Dorset. In 1924, it was renamed in honour of Irish nationalism, nationalist leader Daniel O'Connell, whose statue by John Henry Foley stands at the lower end of the street facing O'Connell Bridge. The street has played an important part in Irish history and features several important monuments, including statues of O'Connell and trade union leader James Larkin, as well as the Spi ...

Lord Mayor Of Dublin
The Lord Mayor of Dublin ( ga, Ardmhéara Bhaile Átha Cliath) is the honorary title of the chairperson ( ga, Cathaoirleach, links=no ) of Dublin City Council which is the local government body for the city of Dublin, the capital of Ireland. The incumbent, since June 2022, is councillor Caroline Conroy. The office holder is elected annually by the members of the Council. Background The office of Mayor of Dublin was created in June 1229 by Henry III. The office of ''Mayor'' was elevated to '' Lord Mayor'' in 1665 by Charles II, and as part of this process received the honorific The Right Honourable (''The Rt Hon.''). Lord mayors were ''ex-officio'' members of the Privy Council of Ireland, which also entitled them to be addressed as The Right Honourable. Though the Privy Council was ''de facto'' abolished in 1922, the Lord Mayor continued to be entitled to be addressed as The Right Honourable as a result of the Municipal Corporations (Ireland) Act 1840, which granted the title ...

Core Sample
A core sample is a cylindrical section of (usually) a naturally-occurring substance. Most core samples are obtained by drilling with special drills into the substance, such as sediment or rock, with a hollow steel tube, called a core drill. The hole made for the core sample is called the "core hole". A variety of core samplers exist to sample different media under different conditions. More continue to be invented on a regular basis. In the coring process, the sample is pushed more or less intact into the tube. Removed from the tube in the laboratory, it is inspected and analyzed by different techniques and equipment depending on the type of data desired. Core samples can be taken to test the properties of manmade materials, such as concrete, ceramics, some metals and alloys, especially the softer ones. Core samples can also be taken of living things, including human beings, especially of a person's bones for microscopic examination to help diagnose diseases. Methods The compo ...

Shot Peening
Shot peening is a cold working process used to produce a compressive residual stress layer and modify the mechanical properties of metals and composites. It entails striking a surface with shot (round metallic, glass, or ceramic particles) with force sufficient to create plastic deformation."Shot Peening," ''Tool and Manufacturing Engineers Handbook'' (TMEH), Volume 3, Society of Manufacturing Engineers, 1985 In machining, shot peening is used to strengthen and relieve stress in components like steel automobile crankshafts and connecting rods. In architecture it provides a muted finish to metal. Shot peening is similar mechanically to sandblasting, though its purpose is not to remove material, but rather it employs the mechanism of plasticity to achieve its goal, with each particle functioning as a ball-peen hammer. Details Peening a surface spreads it plastically, causing changes in the mechanical properties of the surface. Its main application is to avoid the propagation ...

Tuned Mass Damper
A tuned mass damper (TMD), also known as a harmonic absorber or seismic damper, is a device mounted in structures to reduce mechanical vibrations, consisting of a mass mounted on one or more damped springs. Its oscillation frequency is tuned to be similar to the resonant frequency of the object it is mounted to, and reduces the object's maximum amplitude while weighing much less than it. TMDs can prevent discomfort, damage, or outright structural failure. They are frequently used in power transmission, automobiles and buildings. Principle Tuned mass dampers stabilize against violent motion caused by harmonic vibration. They use a comparatively lightweight component to reduce the vibration of a system so that its worst-case vibrations are less intense. Roughly speaking, practical systems are tuned to either move the main mode away from a troubling excitation frequency, or to add damping to a resonance that is difficult or expensive to damp directly. An example of the lat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sculpture
Sculpture is the branch of the visual arts that operates in three dimensions. Sculpture is the three-dimensional art work which is physically presented in the dimensions of height, width and depth. It is one of the plastic arts. Durable sculptural processes originally used carving (the removal of material) and modelling (the addition of material, as clay), in stone, metal, ceramic art, ceramics, wood and other materials but, since Modernism, there has been an almost complete freedom of materials and process. A wide variety of materials may be worked by removal such as carving, assembled by welding or modelling, or Molding (process), moulded or Casting, cast. Sculpture in stone survives far better than works of art in perishable materials, and often represents the majority of the surviving works (other than pottery) from ancient cultures, though conversely traditions of sculpture in wood may have vanished almost entirely. However, most ancient sculpture was brightly painted, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
