Rotor Syndrome
Rotor syndrome (also known as Rotor type hyperbilirubinemia) is a rare cause of mixed direct (conjugated) and indirect (unconjugated) hyperbilirubinemia, relatively benign, autosomal recessive bilirubin disorder characterized by non-hemolytic jaundice due to the chronic elevation of predominantly conjugated bilirubin. Rotor type hyperbilirubinemia is a distinct yet similar disorder to Dubin–Johnson syndrome – both diseases cause an increase in conjugated bilirubin. Whereas rotor syndrome differs in that it is a result of impaired hepatocellular storage of conjugated bilirubin that leaks into plasma causing hyperbilirubinemia. Signs and symptoms Rotor syndrome has many features in common with Dubin–Johnson syndrome, an exception being that the liver cells are not pigmented. The main symptom is a non-itching jaundice. There is a rise in bilirubin in the patient's serum, mainly of the conjugated type. It can be differentiated from Dubin–Johnson syndrome in the following ...

Rotor (ride)
The Rotor is an amusement ride designed and patented by German engineer Ernst Hoffmeister in 1948. The ride was first demonstrated at Oktoberfest 1949, and was exhibited at fairs and events throughout Europe, during the 1950s and 1960s. The ride still appears in numerous amusement parks, although travelling variants have been surpassed by the Gravitron. Design and operation The Rotor is a large, upright barrel, rotated at 33 revolutions per minute. The rotation of the barrel creates an inward acting centripetal force supplied by the wall's support's force, equivalent to almost 3 ''g''. Once the barrel has attained full speed, the floor is retracted, leaving the riders stuck to the wall of the drum. At the end of the ride cycle, the drum slows down and gravity takes over. The riders slide down the wall slowly. Most Rotors were constructed with an observation deck. Although Hoffmeister was the designer, most Rotors were constructed under license. In Australia, the Rotors were bui ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rotor (crank)
The crankset (in the US) or chainset (in the UK), is the component of a bicycle drivetrain that converts the reciprocating motion of the rider's legs into rotational motion used to drive the chain or belt, which in turn drives the rear wheel. It consists of one or more sprockets, also called ''chainrings'' or ''chainwheels'' attached to the '' cranks'', ''arms'', or ''crankarms'' to which the pedals attach. It is connected to the rider by the pedals, to the bicycle frame by the bottom bracket, and to the rear sprocket, cassette or freewheel via the chain. Parts Cranks The two ''cranks'', one on each side and usually mounted 180° apart, connect the bottom bracket axle to the pedals. Lengths Bicycle cranks can vary in length to accommodate different sized riders and different types of cycling. Crank length is measured from the center of the pedal spindle to the center of the bottom bracket spindle or axle. The larger bicycle component manufacturers typically offer cr ...

Helicopter Rotor
A helicopter main rotor or rotor system is the combination of several rotary wings (rotor blades) with a control system, that generates the aerodynamic lift force that supports the weight of the helicopter, and the thrust that counteracts aerodynamic drag in forward flight. Each main rotor is mounted on a vertical mast over the top of the helicopter, as opposed to a helicopter tail rotor, which connects through a combination of drive shaft(s) and gearboxes along the tail boom. The blade pitch is typically controlled by the pilot using the helicopter flight controls. Helicopters are one example of rotary-wing aircraft (rotorcraft). The name is derived from the Greek words ''helix'', helik-, meaning spiral; and ''pteron'' meaning wing. Design principles Overview The helicopter rotor is powered by the engine, through the transmission, to the rotating mast. The mast is a cylindrical metal shaft that extends upward from—and is driven by—the transmission. At the top of the mast i ...

Rotor (electric)
The rotor is a moving component of an electromagnetic system in the electric motor, electric generator, or alternator. Its rotation is due to the interaction between the windings and magnetic fields which produces a torque around the rotor's axis.Staff. "Understanding Alternators. What Is an Alternator and How Does It Work." N.p., n.d. Web. 24 November 2014 . Early development An early example of electromagnetic rotation was the first rotary machine built by Ányos Jedlik with electromagnets and a commutator, in 1826-27. Other pioneers in the field of electricity include Hippolyte Pixii who built an alternating current generator in 1832, and William Ritchie's construction of an electromagnetic generator with four rotor coils, a commutator and brushes, also in 1832. Development quickly included more useful applications such as Moritz Hermann Jacobi's motor that could lift 10 to 12 pounds with a speed of one foot per second, about 15 watts of mechanical power in 1834. In 1835, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rotor (Sonic The Hedgehog)
''Sonic the Hedgehog'' was an American comic book series published by Archie Comics, in partnership with Sega. The series was based on Sega's video game franchise, as well as on the 1993 animated series of the same name. After initially beginning with a four-issue miniseries from February to May 1993 (actually November 1992 to February 1993 as the cover dates did not reflect the actual publication dates of the issues), the first full-length issue of the comic was published in July 1993 (actually April 1993). The series ran for 290 issues for over 20 years, earning a place in the 2008 ''Guinness World Records'' for being the "longest-running comic series based on a video game", and it became the longest-running franchise-based comic series in 2015, surpassing Marvel Comics' ''Conan the Barbarian'' (which ran for 275 issues) before it was confirmed cancelled in July 2017 (although the comics ceased release in January of that year), following Sega and Archie Comics' decision to di ...

Rotor (Enigma Machine)
This article contains technical details about the rotors of the Enigma machine. Understanding the way the machine encrypts requires taking into account the current position of each rotor, the ring setting and its internal wiring. Physical design of rotors Image:Enigma-rotor-pin-contacts.jpg, The right side of a rotor, showing the pin electrical contacts. The Roman numeral V identifies the wiring of the rotor. Image:Enigma-rotor-flat-contacts.jpg, The left side of an Enigma rotor, showing the flat (plate) electrical contacts. A single turnover notch is visible on the left edge of the rotor. Rotor electrical view No letter can map to itself, a cryptographic weakness caused by the same wires being used for forwards and backwards legs. Rotor offset The effect of rotation on the rotors can be demonstrated with some examples. As an example, let us take rotor type I of Enigma I (see table below) without any ring setting offset. It can be seen that an is encoded as an , ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rotor Machine
In cryptography, a rotor machine is an electro-mechanical stream cipher device used for encrypting and decrypting messages. Rotor machines were the cryptographic state-of-the-art for much of the 20th century; they were in widespread use in the 1920s–1970s. The most famous example is the German Enigma machine, the output of which was deciphered by the Allies during World War II, producing intelligence code-named ''Ultra''. Description The primary component of a rotor machine is a set of ''rotors'', also termed ''wheels'' or ''drums'', which are rotating disks with an array of electrical contacts on either side. The wiring between the contacts implements a fixed substitution of letters, replacing them in some complex fashion. On its own, this would offer little security; however, before or after encrypting each letter, the rotors advance positions, changing the substitution. By this means, a rotor machine produces a complex polyalphabetic substitution cipher, which changes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rotor (software Project)
The Shared Source Common Language Infrastructure (SSCLI), previously codenamed Rotor, is Microsoft's shared source implementation of the CLI, the core of .NET. Although the SSCLI is not suitable for commercial use due to its license, it does make it possible for programmers to examine the implementation details of many .NET libraries and to create modified CLI versions. Microsoft provides the Shared Source CLI as a reference CLI implementation suitable for educational use. History Beginning in 2001, Microsoft announced they would release part of the .NET Framework infrastructure source code in Shared source through ECMA, as part of the C# and CLI standardization process. In March 2002, Microsoft released version 1.0 of the Shared Source Common Language Infrastructure, also called Rotor. The Shared Source CLI was initially pre-configured to run on Windows, but could also be built on FreeBSD (version 4.7 or newer), and Mac OS X 10.2. It was designed such that the only thing that ...

Nemesis (Isaac Asimov Novel)
''Nemesis'' is a science fiction novel by American writer Isaac Asimov. One of his later science fiction novels, it was published in 1989, three years before his death. The novel is loosely related to the future history of his Robot Series, Empire Series, and Foundation Series, into which Asimov attempted to integrate his science fiction output. This novel is connected to Asimov's other works by several ideas from earlier and later novels, including non-human intelligence, sentient astronomical bodies ("Hallucination"), and rotor engines ('' Fantastic Voyage II: Destination Brain''). Plot summary The novel is set in an era in which interstellar travel is in the process of being discovered and perfected. In Chapter 2, the novel states that the year 2220 was 16 years ago. Accordingly, the bulk of the novel takes place in or around the year 2236. Before the novel's opening, "hyper-assistance", a technology allowing travel at a little slower than the speed of light, is used to move ...
