One Direction
One Direction, often shortened to 1D, are an English-Irish pop boy band formed in London in 2010. The group are composed of Niall Horan, Liam Payne, Harry Styles, Louis Tomlinson, and previously Zayn Malik until his departure from the group in March 2015. The group signed with Simon Cowell's record label Syco Records after forming and finishing third in the seventh series of the British televised singing competition ''The X Factor'' in 2010. Propelled to global success by social media, One Direction's five albums, '' Up All Night'' (2011), '' Take Me Home'' (2012), ''Midnight Memories'' (2013), ''Four'' (2014), and '' Made in the A.M.'' (2015), topped charts in several countries, and generated hit singles including "What Makes You Beautiful" (their first number one on the UK Singles Chart, and the highest debut for a British act on the US ''Billboard'' Hot 100 since 1998), "Live While We're Young", "Best Song Ever", " Story of My Life" and "Drag Me Down".

Alpha-1D Adrenergic Receptor
The alpha-1D adrenergic receptor (α1D adrenoreceptor), also known as ADRA1D, is an alpha-1 adrenergic receptor, and also denotes the human gene encoding it. Receptor There are 3 alpha-1 adrenergic receptor subtypes: alpha-1A, -1B and -1D, all of which signal through the Gq/11 family of G-proteins and different subtypes show different patterns of activation. They activate mitogenic responses and regulate growth and proliferation of many cells. Gene This gene encodes alpha-1D-adrenergic receptor. Similar to alpha-1B-adrenergic receptor gene, this gene comprises 2 exons and a single intron that interrupts the coding region. Ligands ; Antagonists * A-315456 * BMY 7378 (also α2C antagonist) See also *Adrenergic receptor The adrenergic receptors or adrenoceptors are a class of G protein-coupled receptors that are targets of many catecholamines like norepinephrine (noradrenaline) and epinephrine (adrenaline) produced by the body, but also many medications like beta ...

Astra 1D
Astra 1D is a geostationary communications satellite launched in 1994 by the Société Européenne des Satellites (SES). , the craft remains in service for occasional use. Astra 1D was the fourth, and under original plans, last Astra communications satellite from SES. It was launched to SES' original solitary operational position at 19.2° East, and was intended as an in-orbit spare for Astra's Astra 1A, 1B and 1C and to carry digital TV transmissions. However, development of digital reception equipment in Europe was not sufficiently advanced for Astra 1D to be SES' first digital satellite (the later Astra 1E fulfilled that role) and demand for additional capacity for both British and German television channels led to 12 of the satellite's transponders being leased to broadcast analogue TV channels before the satellite had been launched. History After launch to 19.2° East, Astra 1D served two periods as a spare at the Astra 28.2°E position colocated with Astra 2A, for s ...

Canon EOS-1D
The Canon EOS-1D is a professional digital single-lens reflex camera launched in November 2001 as part of Canon's flagship EOS-1 series. It was the first digital camera in the EOS-1 line, succeeding Canon's final flagship film camera, the 1V. It was also the first professional-level digital camera developed and released entirely by Canon, the previous D2000 being a collaborative effort with Kodak. It has a 1.3x crop factor with a image sensor sourced . The camera shares its body design with the Canon EOS-1V 35mm camera (with the additional battery grip attached). It was complemented by the slower, higher-resolution 1Ds in 2002 and succeeded by the 1D Mark II in April 2004. Features The 1D was seen as a major breakthrough for a professional news and sports camera after its predecessors, the Canon EOS DCS series and EOS D2000, which had both been produced in co-operation with Kodak. In comparison with those cameras, the 1D had faster image processing speed, much cleaner high ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Long March 1D
The Long March 1D was a member of China's Long March rocket family. During the 1990s CALT developed an improved version of the DF-4 to test the reentry vehicle warheads of the DF-31. They took advantage of this development and offered it as the Long March 1D for commercial application. The modifications included: * An DF-4 improved first stage, which used the new version of the YF-2B, and switched propellants to UDMH/ N2O4 for improved performance. * The replacement of the DF-4 second stage motor YF-3A. The proposed replacement was the Long March 4 third stage engine, the YF-40. * A new inline inter-stage would replace the existing tapered connector between the second and third stages, which allowed for an additional 70cm diameter to be added to the third stage skirt. This would allow for the addition of RCS to the third stage. * A new third stage with a new motor, the FG-36 and an optional RCS. * A new computer inertial guidance system which enabled the third stage to be 3-axi ...

One-dimensional Space
In physics and mathematics, a sequence of ''n'' numbers can specify a location in ''n''-dimensional space. When , the set of all such locations is called a one-dimensional space. An example of a one-dimensional space is the number line, where the position of each point on it can be described by a single number. In algebraic geometry there are several structures that are technically one-dimensional spaces but referred to in other terms. A field ''k'' is a one-dimensional vector space over itself. Similarly, the projective line over ''k'' is a one-dimensional space. In particular, if , the complex numbers, then the complex projective line P1(ℂ) is one-dimensional with respect to ℂ, even though it is also known as the Riemann sphere. More generally, a ring is a length-one module over itself. Similarly, the projective line over a ring is a one-dimensional space over the ring. In case the ring is an algebra over a field, these spaces are one-dimensional with respect to the algebr ...

Penny (British Pre-decimal Coin)
The British pre-decimal penny was a denomination of sterling coinage worth of one pound or of one shilling. Its symbol was ''d'', from the Roman denarius. It was a continuation of the earlier English penny, and in Scotland it had the same monetary value as one pre-1707 Scottish shilling. The penny was originally minted in silver, but from the late 18th century it was minted in copper, and then after 1860 in bronze. The plural of "penny" is "pence" when referring to an amount of money, and "pennies" when referring to a number of coins. Thus 8''d'' is eight pence, but "eight pennies" means specifically eight individual penny coins. Before Decimal Day in 1971, sterling used the Carolingian monetary system (£sd), under which the largest unit was a pound (£) divisible into 20 shillings (s), each of 12 pence (d). The penny was withdrawn in 1971 due to decimalisation, and replaced (in effect) by the decimal half new penny, with p being worth 1.2''d''. History The kingdoms o ...

C0 And C1 Control Codes
The C0 and C1 control code or control character sets define control codes for use in text by computer systems that use ASCII and derivatives of ASCII. The codes represent additional information about the text, such as the position of a cursor, an instruction to start a new line, or a message that the text has been received. C0 codes are the range 00 HEX–1FHEX and the default C0 set was originally defined in ISO 646 (ASCII). C1 codes are the range 80HEX–9FHEX and the default C1 set was originally defined in ECMA-48 (harmonized later with ISO 6429). The ISO/IEC 2022 system of specifying control and graphic characters allows other C0 and C1 sets to be available for specialized applications, but they are rarely used. C0 controls ASCII defined 32 control characters, plus a necessary extra character for the DEL character, 7FHEX or 01111111BIN (needed to punch out all the holes on a paper tape and erase it). This large number of codes was desirable at the time, as multi ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
