The coulomb (symbol: C) is the unit of electric charge in the International System of Units (SI). In the present version of the SI it is equal to the electric charge delivered by a 1 ampere constant current in 1 second and to 5×1027/801088317 elementary charges, e, (about 6.241509×1018e).
The Bukit Panjang LRT (BPLRT) is a 7.6-kilometre (4.7 mi) automated guideway transit line in Bukit Panjang, Singapore. The BPLRT is currently the only LRT line operated by SMRT Trains. As the name suggests, it serves 13 stations in the neighbourhood of Bukit Panjang and parts of Choa Chu Kang in the north-west of the country. The line was the first LRT line constructed in Singapore, having opened on 6 November 1999 by then Deputy Prime Minister Tony Tan.
Dizocilpine (INN), also known as MK-801, is a pore blocker of the N-Methyl-D-aspartate (NMDA) receptor, a glutamate receptor, discovered by a team at Merck in 1982. Glutamate is the brain's primary excitatory neurotransmitter. The channel is normally blocked with a magnesium ion and requires depolarization of the neuron to remove the magnesium and allow the glutamate to open the channel, causing an influx of calcium, which then leads to subsequent depolarization. Dizocilpine binds inside the ion channel of the receptor at several of PCP's binding sites thus preventing the flow of ions, including calcium (Ca2+), through the channel. Dizocilpine blocks NMDA receptors in a use- and voltage-dependent manner, since the channel must open for the drug to bind inside it. The drug acts as a potent anti-convulsant and probably has dissociative anesthetic properties, but it is not used clinically for this purpose because of the discovery of brain lesions, called Olney's lesions (see below), in laboratory rats. Dizocilpine is also associated with a number of negative side effects, including cognitive disruption and psychotic-spectrum reactions. It inhibits the induction of long term potentiation and has been found to impair the acquisition of difficult, but not easy, learning tasks in rats and primates. Because of these effects of dizocilpine, the NMDA receptor pore blocker ketamine is used instead as a dissociative anesthetic in human medical procedures. While ketamine may also trigger temporary psychosis in certain individuals, its short half-life and lower potency make it a much safer clinical option. However, dizocilpine is the most frequently used uncompetitive NMDA receptor antagonist in animal models to mimic psychosis for experimental purposes.
HNLMS De Ruyter may refer to one of nine ships of the Royal Netherlands Navy named after Admiral Michiel Adriaenszoon de Ruyter (1607–1676):
Deadweight tonnage or tons deadweight (DWT) is a measure of how much weight a ship can carry. It is the sum of the weights of cargo, fuel, fresh water, ballast water, provisions, passengers, and crew.
Mangabeys are West African Old World monkeys, with species in three of the six genera of tribe Papionini.
801 Grand High Rise Building is a 45-story skyscraper in Des Moines, Iowa, United States, operated and managed by JLL Americas and owned by Principal Financial Group. The 801 Grand Building was constructed in 1989 and is the tallest building in Iowa. The building is part of a larger downtown campus run by Principal Financial Group and features a skywalk and an eight-sided copper pyramid at its top.
801 Naval Air Squadron (NAS) was a Fleet Air Arm squadron of the Royal Navy formed in 1933 which fought in World War II, the Korean War and the Falklands War.
JTC-801 is an opioid analgesic drug used in scientific research.
The YJ-8 is a Chinese surface-launched subsonic anti-ship cruise missile. It is manufactured by the China Aerospace Science and Industry Corporation (CASIC) Third Academy.
801 is a year in the Common Era.
German submarine U-801 was a Type IXC/40 U-boat built for Nazi Germany's Kriegsmarine during World War II.
The Bombardier Innovia APM 100 C801A is the second generation of an automated people mover (APM) train built by Bombardier Transportation for the Bukit Panjang LRT line. These trains are mainly for airport connections and light rail in towns and it is operated by Automatic Train Control (ATC), making it fully automatic and driverless. The use of rubber tyres and ceramic tracks are extremely quiet compared to conventional rail.
The Bombardier Innovia APM 100 C801 is the first generation of an automated people mover (APM) train built by Adtranz for use on the Bukit Panjang LRT (BPLRT).
Intelsat 801 is a geosynchronous communications spacecraft that was launched on March 01, 1997 by an Ariane 44L rocket from Kourou in French Guiana to provide voice and video communications to the member countries in that consortium after parking at 174° E longitude. It carries 38 C Band and 6 Ku Band transponders. It was built for US$76 million, launched for US$86 million and insured for US$27 million.
The Bombardier Innovia APM 300R C801B is the third generation of automated people mover (APM) trains built by CRRC Puzhen Alstom Transportation Systems for the Bukit Panjang LRT line, to replace the existing C801 trains built in 1999. The C801B trains are also the first of its kind to reuse the retro AC third rail shoes compared to the newer Light Rail lines around the world that utilises the APM 300 system that have been built with DC third rail instead of AC.
