Monitor Warship Type
A monitor is a relatively small warship which is neither fast nor strongly armored but carries disproportionately large guns. They were used by some navies from the 1860s, during the First World War and with limited use in the Second World War. The original monitor was designed in 1861 by John Ericsson, who named it . They were designed for shallow waters and served as coastal ships. The term also encompassed more flexible breastwork monitors, and was sometimes used as a generic term for any turreted ship. In the early 20th century, the term was revived for shallow-draught armoured shore bombardment vessels, particularly those of the Royal Navy: the s carried guns firing heavier shells than any other warship ever has, seeing action (albeit briefly) against German targets during World War I. The ''Lord Clive'' vessels were scrapped in the 1920s. The term "monitor" also encompasses the strongest of riverine warcraft, known as river monitors. During the Vietnam War these ...

Monitor Model
The input hypothesis, also known as the monitor model, is a group of five hypotheses of second-language acquisition developed by the linguist Stephen Krashen in the 1970s and 1980s. Krashen originally formulated the input hypothesis as just one of the five hypotheses, but over time the term has come to refer to the five hypotheses as a group. The hypotheses are the input hypothesis, the acquisition–learning hypothesis, the monitor hypothesis, the natural order hypothesis and the affective filter hypothesis. The input hypothesis was first published in 1977. The hypotheses put primary importance on the comprehensible input (CI) that language learners are exposed to. Understanding spoken and written language input is seen as the only mechanism that results in the increase of underlying linguistic competence, and language output is not seen as having any effect on learners' ability. Furthermore, Krashen claimed that linguistic competence is only advanced when language is subconsci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battle Of Hampton Roads
The Battle of Hampton Roads, also referred to as the Battle of the ''Monitor'' and ''Virginia'' (rebuilt and renamed from the USS ''Merrimack'') or the Battle of Ironclads, was a naval battle during the American Civil War. It was fought over two days, March 8–9, 1862, in Hampton Roads, a roadstead in Virginia where the Elizabeth and Nansemond rivers meet the James River just before it enters Chesapeake Bay adjacent to the city of Norfolk. The battle was a part of the effort of the Confederacy to break the Union blockade, which had cut off Virginia's largest cities and major industrial centers, Norfolk and Richmond, from international trade.Musicant 1995, pp. 134–178; Anderson 1962, pp. 71–77; Tucker 2006, p. 151. This battle has major significance because it was the first meeting in combat of ironclad warships, and . The Confederate fleet consisted of the ironclad ram ''Virginia'' (built from the remnants of the burned steam frigate , newest warship for the United Stat ...

Miguel Grau Seminario
Miguel María Grau Seminario (27 July 1834 – 8 October 1879) was the most renowned Peruvian naval officer and hero of the naval battle of Angamos during the War of the Pacific (1879–1884). He was known as ''el Caballero de los Mares'' (Spanish for "Gentleman of the Seas") for his kind and chivalrous treatment of defeated enemies and is esteemed by both Peruvians and Chileans. He is an iconic figure for the Peruvian Navy, and one of the most famous merchant marine and naval military leaders of the Americas. Early life Miguel Grau was born in Paita on 27 July 1834 in the house of Dr. Alexander Diamont Newel with the assistance of the midwife Tadea Castillo, also known as "The Morito," both prominent figures in Paita. His father was Juan Manuel Grau y Berrío, a Colombian who came to Peru with Bolivar in the fight for independence from Spain. Later, Juan bought property in Paita and worked at the Customs Office. His mother, Luisa Seminario y del Castillo, motivated Grau to lov ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birkenhead, England
Birkenhead (; cy, Penbedw) is a town in the Metropolitan Borough of Wirral, Merseyside, England; historically, it was part of Cheshire until 1974. The town is on the Wirral Peninsula, along the south bank of the River Mersey, opposite Liverpool. At the 2011 census, it had a population of 88,818. Birkenhead Priory and the Mersey Ferry were established in the 12th century. In the 19th century, Birkenhead expanded greatly as a consequence of the Industrial Revolution. Birkenhead Park and Hamilton Square were laid out as well as the first street tramway in Britain. The Mersey Railway connected Birkenhead and Liverpool with the world's first tunnel beneath a tidal estuary; the shipbuilding firm Cammell Laird and a seaport were established. In the second half of the 20th century, the town suffered a significant period of decline, with containerisation causing a reduction in port activity. The Wirral Waters development is planned to regenerate much of the dockland. Toponymy Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ram (ship)
A ram was a weapon fitted to varied types of ships, dating back to antiquity. The weapon comprised an underwater prolongation of the bow of the ship to form an armoured beak, usually between 2 and 4 meters (6–12 ft) in length. This would be driven into the hull of an enemy ship to puncture, sink or disable it. Ancient rams It was possibly developed in late Bronze age Egypt, but it only became widely used in later Iron age Mediterranean galleys. The ram was a naval weapon in the Greek/Roman antiquity and was used in such naval battles as Salamis and Actium. Naval warfare in the Mediterranean rarely used sails, and the use of rams specifically required oarsmen rather than sails in order to maneuver with accuracy and speed, and particularly to reverse the movement of a ramming ship to disentangle it from its sinking victim, lest it be pulled down when its victim sank. The Athenians were especially known for their ''diekplous'' and '' periplous'' tactics that disabled enemy ships ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Spar Torpedo
A spar torpedo is a weapon consisting of a bomb placed at the end of a long pole, or spar, and attached to a boat. The weapon is used by running the end of the spar into the enemy ship. Spar torpedoes were often equipped with a barbed spear at the end, so it would stick to wooden hulls. A fuse could then be used to detonate it. Invention Robert Fulton had written about submarine (i.e., subsurface) marine torpedoes in 1810, and experiments were conducted using spar torpedoes that year. Boats carrying spar torpedoes were used during the War of 1812. E. C. Singer, a private engineer who worked on secret projects for the benefit of the Confederate States of America, constructed a spar torpedo during the American Civil War. His torpedo was detonated by means of a trigger mechanism adapted from a rifle lock (see flintlock mechanism for a similar device). The spring-loaded trigger was detonated by means of a long cord attached to the attacking vessel. The attacking vessel rammed its ...

Paddle Steamer
A paddle steamer is a steamship or steamboat powered by a steam engine that drives paddle wheels to propel the craft through the water. In antiquity, paddle wheelers followed the development of poles, oars and sails, where the first uses were wheelers driven by animals or humans. In the early 19th century, paddle wheels were the predominant way of propulsion for steam-powered boats. In the late 19th century, paddle propulsion was largely superseded by the screw propeller and other marine propulsion systems that have a higher efficiency, especially in rough or open water. Paddle wheels continue to be used by small, pedal-powered paddle boats and by some ships that operate tourist voyages. The latter are often powered by diesel engines. Paddle wheels The paddle wheel is a large steel framework wheel. The outer edge of the wheel is fitted with numerous, regularly spaced paddle blades (called floats or buckets). The bottom quarter or so of the wheel travels under water. An e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
