Professional Darts Corporation
The Professional Darts Corporation (PDC) is a professional darts organisation in the United Kingdom, established in 1992 when a group of leading players split from the British Darts Organisation (BDO) to form what was initially called the World Darts Council (WDC). Sports promoter Eddie Hearn is the PDC chairman. The PDC developed and holds several championship competitions, including the annual PDC World Darts Championship, the World Matchplay, World Grand Prix, UK Open, Premier League, and Grand Slam. It also runs its own world rankings based on players' performances. History In the 1980s, professional darts in Britain lost much of its sponsorship television coverage. From 1989, the only televised event was the annual Embassy World Championship. Some of the players felt that not enough was being done by the governing body, the British Darts Organisation, to encourage new sponsors into the sport and arrange more television coverage than just one event a year. As a result ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

PDC (gang)
The PDC (Pray Days Change, Public Demand Cartel, or Poverty Driven Children, formerly Peel Dem Crew or Pussy Drugs Cash) was a street gang based in Brixton, London, England, mainly the Angell Town Estate. During the 1990s, they were the largest and most prominent gang in the SW9 postcode. Members were known to be involved in the drugs trade, robberies, shootings, stabbings and general violence. The gang associated with the colours red and purple. Following Ja-Ja's release from prison, he encouraged members of the gang to do more positive things with their lives and reformed PDC as a music collective and label. They released an album, Pray Days Change, and several music videos.Kemp, Ross; ''Gangs''; Penguin UK, 2008 A faction of the PDC meanwhile broke off and converted to Islam in search of an identity while still continuing to engage in crime.

Personal Digital Cellular
Personal Digital Cellular (PDC) was a 2G mobile telecommunications standard used exclusively in Japan. After a peak of nearly 80 million subscribers to PDC, it had 46 million subscribers in December 2005, and was slowly phased out in favor of 3G technologies like W-CDMA and CDMA2000. At the end of March 2012, the count had dwindled down to almost 200,000 subscribers. NTT Docomo shut down their network, mova, on April 1, 2012 at midnight. Technical overview Like D-AMPS and GSM, PDC uses TDMA. The standard was defined by the RCR (later became ARIB) in April 1991, and NTT DoCoMo launched its Digital mova service in March 1993. PDC uses 25 kHz carrier, pi/4-DQPSK modulation with 3-timeslot 11.2 kbit/s (full-rate) or 6-timeslot 5.6 kbit/s (half-rate) voice codecs. PDC is implemented in the 800 MHz (downlink 810–888 MHz, uplink 893–958 MHz), and 1.5 GHz (downlink 1477–1501 MHz, uplink 1429–1453 MHz) bands. The air interface is ...

Pyruvate Dehydrogenase Complex
Pyruvate dehydrogenase complex (PDC) is a complex of three enzymes that converts pyruvate into acetyl-CoA by a process called pyruvate decarboxylation. Acetyl-CoA may then be used in the citric acid cycle to carry out cellular respiration, and this complex links the glycolysis metabolic pathway to the citric acid cycle. Pyruvate decarboxylation is also known as the "pyruvate dehydrogenase reaction" because it also involves the oxidation of pyruvate. This multi-enzyme complex is related structurally and functionally to the oxoglutarate dehydrogenase and branched-chain oxo-acid dehydrogenase multi-enzyme complexes. Reaction The reaction catalysed by pyruvate dehydrogenase complex is: Structure Pyruvate dehydrogenase (E1) The E1 subunit, called the pyruvate dehydrogenase subunit, has a structure that consists of two chains (an “ɑ” and “ꞵ” chain). A magnesium ion forms a 4-coordinate complex with three, polar amino acid residues (Asp, Asn, and Tyr) located on t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Programme Delivery Control
Programme delivery control (PDC) is specified by the standard ETS 300 231 (ETSI EN 300 231), published by the European Telecommunications Standards Institute (ETSI). This specifies the signals sent as hidden codes in the teletext service, indicating when transmission of a programme starts and finishes. PDC (also known as Enhanced Teletext Packet 8/30 Format 2) is often used together with StarText, enabling the user to select a programme to record using specially coded teletext programme listings. The combination of features is often called PDC/StarText. In Germany and some other European countries, the older standard video programming system (VPS) is in use also known as format 2. Effectively, the two systems do the same thing and most modern VCRs and stand-alone DVD recorders work with both signals. The VPS system was invented by Mit-hat Sheqerolli in April 1983 under the name of "Run-time controller for the recordings of television programmes by means of a videorecorder". In ...

Pulsed DC
Pulsed DC (PDC) or pulsating direct current is a periodic current which changes in value but never changes direction. Some authors use the term pulsed DC to describe a signal consisting of one or more rectangular ("flat-topped"), rather than sinusoidal, pulses. Pulsed DC is commonly produced from AC (alternating current) by a half-wave rectifier or a full-wave rectifier. Full wave rectified ac is more commonly known as Rectified AC. PDC has some characteristics of both alternating current (AC) and direct current (DC) waveforms. The voltage of a DC wave is roughly constant, whereas the voltage of an AC waveform continually varies between positive and negative values. Like an AC wave, the voltage of a PDC wave continually varies, but like a DC wave, the sign of the voltage is constant. Pulsating direct current is used on PWM controllers. Smoothing Most modern electronic items function using a DC voltage, so the PDC waveform must usually be smoothed before use. A reservoir capaci ...

Catalan European Democratic Party
The Catalan European Democratic Party ( ca, Partit Demòcrata Europeu Català, PDeCAT, sometimes stylized as PDECat), initially branded as the Catalan Democratic Party ( ca, Partit Demòcrata Català, PDC), is a liberal political party in Spain that supports Catalan independence. The party was founded in Barcelona on 10 July 2016. PDeCAT is regarded as the successor party to Democratic Convergence of Catalonia (CDC), which for most its history was a constituent party of the Convergence and Union (CiU) political formation. The party declared to have 14,000 members in the 2018–2019 period, but this number has recently been revised down to figures as low as 5,000 as a result of internal infighting over former Catalan president Carles Puigdemont's strategy and a number of party splits. History Early development Democratic Convergence of Catalonia (CDC) held its last congress on 8 July 2016, in which CDC's members agreed to its "refoundation" into a new political party, whose foundi ...

Phosducin
Phosducin, also known as PDC, is a human protein and gene. It belongs to the phosducin family of proteins. This gene encodes a phosphoprotein, which is located in the outer and inner segments of the rod cells in the retina. This protein may participate in the regulation of visual phototransduction or in the integration of photoreceptor metabolism. It modulates the phototransduction cascade by interacting with the beta and gamma subunits of the retinal G-protein transducin. By associating with these subunits only, the Transducin alpha subunit will remain active for longer. This will increase the amount of time of visual excitation. This gene is a potential candidate gene for retinitis pigmentosa Retinitis pigmentosa (RP) is a genetic disorder of the eyes that causes loss of vision. Symptoms include trouble seeing at night and decreasing peripheral vision (side and upper or lower visual field). As peripheral vision worsens, people may ... and Usher syndrome type II. Alterna ...
