 In the Dindsenchas Nechtan is described as the husband of Boann and the son of Nuadu.
A kiddie ride - or kids' ride - is a coin-operated amusement ride for young children.
 Kiddie rides are commonly available in amusement parks, arcades, malls, hotel game rooms and outside supermarkets and discount department stores.
 Less commonly, they may also appear in other venues such as restaurants, food courts, grocery shops and auto dealerships.
 When activated by a coin, a kiddie ride entertains the rider with motion, depending on the ride type (miniature Ferris wheel, miniature carousel, track ride or stationary platform ride).
 Most rides include sounds and music, and some feature flashing lights, pedals, and buttons. Commercial kiddie rides often use simple but colorful equipment, with the driving mechanism usually hidden under vacuum formed plastic covers.
Fantasy Island is a family amusement park in Ingoldmells on the East Coast of England.
 It sits in the middle of one of the biggest spreads of holiday parks in the United Kingdom.
 Whilst entry to the park is free, guests either pay per ride or purchase an unlimited ride wristband.
 The pay-per-ride option uses a live ticket, which has a printed bar code that can be scanned to gain access to rides.
 This option allows credit to be added to the ticket to be able to ride rides in the park.
 Rides are priced at £1.50, £2.50, or £4.00 per ride depending on the ride type.
Polka Marina is a Merry-go-round in amusement park Efteling in the Netherlands.
 It started operating in 1984.
A carousel (American English: from French "carrousel" and Italian "carosello"), roundabout (British English), or merry-go-round, is an amusement ride consisting of a rotating circular platform with seats for riders.
 The "seats" are traditionally in the form of rows of wooden horses or other animals mounted on posts, many of which are moved up and down by gears to simulate galloping, to the accompaniment of looped circus music.
 This leads to one of the alternative American names, the galloper.
 Other popular names are jumper, horseabout and flying horses.
Viper is a steel roller coaster made by Arrow Dynamics of the United States.
 The roller coaster is located in the Baja Ridge area of Six Flags Magic Mountain in Valencia, California.
 Viper is the last of the three 7-looper roller coasters built by Arrow Dynamics to remain operating.
 The other two, Shockwave at Six Flags Great America and the Great American Scream Machine at Six Flags Great Adventure, were demolished in 2002 and 2010, respectively.
 The roller coaster replaced a HUSS ride type named Condor.
DA2PP, is a multivalent vaccine for dogs that protects against the viruses indicated by the alphanumeric characters forming the acronym: D for canine distemper, A2 for canine adenovirus type 2, which offers cross-protection to canine adenovirus type 1 (the more pathogenic of the two strains) (see Canine adenovirus), the first P for canine parvovirus, and the second P for parainfluenza.
 Because infectious canine hepatitis is another name for canine adenovirus type 1, an H is sometimes used instead of A.
 In DA2PPC, the C indicates canine coronavirus.
Submission was a Chance Rides Double Swinging Inverter located in the X-Sector area and was built in 2001.
 From 2005, the ride only operated one of its arms to save electricity and the ride's cycles were shortened.
 The slogan used in advertisement was 'Hang in there'.
 Following the area's theme, the ride was painted blue and was covered in a shiny metal, most likely steel.
 Each of its two arms had a counterweight in the shape of two metal spikes, which would sweep near to the ground like a scythe.
 The sequence was always the same, different to some other weight based rides that have numerous sequences, this was also probably to be more energy efficient.
 The Ride type itself is a rare flat-ride and not seen at a lot of themeparks, Submission did not have the best of reviews at Alton Towers mainly due to it having the same sequence (unlike others such as Ripsaw), the restraints were very similar to those on a Huss Top Spinner making it fairly uncomfortable to ride when inverted, breakdowns occasionally happened and as a result, queues were very short.
 In 2013 it was later revealed that Submission would be closed after the end of the 2013 season by which there is a vacant grass area where it once stood next to the break-block section on Oblivion.
 The grass area is often referred to as the 'Submission memorial ground' by thrill-seekers which has become a popular sitting area in the park section.
An Impulse roller coaster is a form of a launched inverted roller coaster manufactured by Intamin.
 The first Impulse roller coaster appeared in Japan, and the ride type has since evolved to include four specific layouts, three of these varieties being built in the USA.
 It uses LIMs to launch a train out of the station and (in most installations) up a vertical spiral.
 The train then falls backwards, is powered again through the station, and heads up a back tower.
 The train then falls forwards, and continues in this fashion for a total of 2½ cycles per ride (three forward launches, two backwards).
 On the final forward launch, with a slightly reduced speed, the train is sent up the front tower, and brakes then deploy on the launch track.
 The train then slows down and heads back into the station.
"Microdontosaurus" (meaning "tiny-toothed lizard") is the name given to an as yet undescribed genus of sauropod dinosaur from China.
 It was named from fossils from the Middle Jurassic-age Dapuka Group of Xinjiang, and assigned to the Homalosaurpoidea, an outdated classification of diplodocids and titanosaurs.
 The intended type species is "M. dayensis."
 As with other informal names created by Zhao in 1985 or 1983, it has not been used since then, and may have been redescribed under another name.
