CP1 (classification)
CP1 is a disability sport classification specific to cerebral palsy. In many sports, it is grouped inside other classifications to allow people with cerebral palsy to compete against people with other different disabilities but the same level of functionality. CP1 classified competitors are the group who are most physically affected by their cerebral palsy. They are quadriplegics. The most popular sport for people in this class is boccia, where they are classified as either BC1 or BC3. Other sports open to competitors in this class include athletics, cycling, race running, slalom, and swimming. In some of these sports, different classification systems or names for CP1 are used. Definition and participation CP1 classified competitors are the group who are most physically affected by their cerebral palsy. They are most likely to participate in boccia. Cerebral Palsy-International Sports and Recreation Association (CP-ISRA) defined this class in January 2005 as, "Quadriplegic ...

Am Star
An Am star or metallic-line star is a type of chemically peculiar star of spectral type A whose spectrum has strong and often variable absorption lines of metals such as zinc, strontium, zirconium, and barium, and deficiencies of others, such as calcium and scandium. The original definition of an Am star was one in which the star shows "an apparent surface underabundance of Ca (and/or Sc) and/or an apparent overabundance of the Fe group and heavier elements". The unusual relative abundances cause the spectral type assessed from the Calcium K lines to be systematically earlier than one assessed from other metallic lines. Typically, a spectral type judged solely from hydrogen lines is intermediate. This leads to two or three spectral types being given. For example, Sirius has been given a spectral type of kA0hA0VmA1, indicating that it is A0 when judged by the Calcium k line, A0V when judged by its hydrogen lines, and A1 when judged by the lines of heavy metals. There are othe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chicago Pile-1
Chicago Pile-1 (CP-1) was the world's first artificial nuclear reactor. On 2 December 1942, the first human-made self-sustaining nuclear chain reaction was initiated in CP-1, during an experiment led by Enrico Fermi. The secret development of the reactor was the first major technical achievement for the Manhattan Project, the Allied effort to create atomic bombs during World War II. Developed by the Metallurgical Laboratory at the University of Chicago, CP-1 was built under the west viewing stands of the original Stagg Field. Although the project's civilian and military leaders had misgivings about the possibility of a disastrous runaway reaction, they trusted Fermi's safety calculations and decided they could carry out the experiment in a densely populated area. Fermi described the reactor as "a crude pile of black bricks and wooden timbers". The reactor was assembled in November 1942, by a team that included Fermi, Leo Szilard (who had previously formulated an idea for no ...

Complex Projective Line
In mathematics, the Riemann sphere, named after Bernhard Riemann, is a model of the extended complex plane: the complex plane plus one point at infinity. This extended plane represents the extended complex numbers, that is, the complex numbers plus a value \infty for infinity. With the Riemann model, the point \infty is near to very large numbers, just as the point 0 is near to very small numbers. The extended complex numbers are useful in complex analysis because they allow for division by zero in some circumstances, in a way that makes expressions such as 1/0=\infty well-behaved. For example, any rational function on the complex plane can be extended to a holomorphic function on the Riemann sphere, with the poles of the rational function mapping to infinity. More generally, any meromorphic function can be thought of as a holomorphic function whose codomain is the Riemann sphere. In geometry, the Riemann sphere is the prototypical example of a Riemann surface, and is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vektor CP1
The Vektor СР1 is a semi-automatic pistol that was made in South Africa by Lyttleton Engineering Works (LIW) now Denel Land Systems, from 1996 to 2001. Design The CP1 pistol was intended as a concealed carry weapon for law enforcement and civilian use. It has an unusual, streamlined design with a polymer frame and an even more unusual safety, located at the front of the trigger-guard. In several reviews it was characterized as being a radically designed gun that looks like something straight out of a science fiction movie. These reviews stated that it has no sharp edges, and is about as "snag-proof" as any combat gun can ever be, and because of its design it is a surprisingly comfortable gun to shoot, which makes it feel very ergonomic. The pistol originally sold in the United States for a retail price of approximately $400. The pistol was marketed in Italy, where it was chambered for the 9×21mm IMI cartridge. The CP1 uses a gas-delayed blowback action with a gas cylinder ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Warren CP-1
The Warren CP-1, also called Miss Poly, Miss Polytechnic and the Warren Monoplane, was the second aircraft built by engineering students at California Polytechnic State University, California Polytechnic College, after their first project the Mason Greater Meteor. Design and development The CP-1 was built for Cal Poly instructor Martin C. Martinsen and completed in August 1929. It was a high-wing conventional landing gear equipped monoplane using dual airfoil-shaped lift struts. The fuselage is made of fabric-covered welded steel tubing, with wooden wing spars and ribs. The red, yellow and blue paint scheme was taken a from an earlier Berrylold Paint advertisement. An exhaust collector ring, larger rudder and low-pressure wheels and tires were added after construction. Operational history The CP-1 was licensed as an experimental aircraft and test flown from E.W. Clark Field in September 1929. It won a silver cup and two blue ribbons at the California State Fair, and on 29 June 19 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pasir Ris MRT Station
Pasir Ris MRT station is an elevated Mass Rapid Transit (MRT) station on the East West line (EWL) in Pasir Ris, Singapore. Situated along Pasir Ris Central adjacent to Pasir Ris Bus Interchange and the White Sands Shopping Mall, it is the eastern terminus of the EWL and, as of June 2021, the only MRT station within Pasir Ris. The station exterior has the characteristic dome-shaped segmented roof also seen on other elevated EWL stations. The station opened on 16 December 1989 as the terminus of the MRT's eastern line extension. In 2016, two maintenance workers were killed on the tracks away from the station. In January 2019, it was announced that the station would become an interchange, with the opening of the Cross Island line (CRL) by 2030. The station is also planned to be the terminus for the future CRL branch extension to Punggol station in 2032, as announced in March 2020. History The station was constructed as the terminus of an extension of the East West MRT lin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
