Planet Nine
Planet Nine is a hypothetical planet in the outer region of the Solar System. Its gravitational effects could explain the peculiar clustering of orbits for a group of extreme trans-Neptunian objects (ETNOs), bodies beyond Neptune that orbit the Sun at distances averaging more than 250 times that of the Earth. These ETNOs tend to make their closest approaches to the Sun in one sector, and their orbits are similarly tilted. These alignments suggest that an undiscovered planet may be shepherding the orbits of the most distant known Solar System objects. Nonetheless, some astronomers question this conclusion and instead assert that the clustering of the ETNOs orbits is due to observational biases, resulting from the difficulty of discovering and tracking these objects during much of the year. Based on earlier considerations, this hypothetical super-Earth-sized planet would have had a predicted mass of five to ten times that of the Earth, and an elongated orbit 400 to 800 times as ...

Boeing XP-9
The Boeing XP-9 (company Model 96) was the first monoplane fighter aircraft produced by the United States aircraft manufacturing company Boeing. It incorporated sophisticated structural refinements that were influential in later Boeing designs. The sole prototype exhibited unsatisfactory characteristics with its lack of pilot visibility directly leading to its cancellation. Design and development The XP-9 was designed in 1928 to meet the requirements of a US Army request for a monoplane fighter. Its primary contribution to aircraft design was its semi-monocoque construction, which would become a standard for future aircraft. Boeing employed the structural features of the XP-9 into their contemporary P-12 biplane fighter when the P-12E variant incorporated a semi-monocoque metal fuselage structure similar to that of the XP-9. The undercarriage arrangement of the P-12C had also been first tried out on the XP-9 and then transferred into the production model.''Pedigree of Champions ...

Heckler & Koch P9
The HK P9 is a semi-automatic pistol from Heckler & Koch in 9×19mm Parabellum, .45 ACP, and 7.65×21mm Parabellum and the first to use a variation of H&K's roller delayed blowback system in a pistol format and polygonal rifling now common in H&K designs. Design The P9 is a roller-delayed pistol manufactured from a stamped steel main frame and a polymer trigger guard. The stamped steel slide contains machined internal parts including a polygonally rifled barrel. High-profile fixed sights are fitted with two red rectangles on the rear sight and a white stripe on the drift adjustable front blade sight. Vertical zeroing is accomplished by fitting front sights of a different height. The P9S trigger operates as a traditional double action. There is a lever on the left side of the pistol grip to both decock a cocked hammer or to manually re-cock it for a single action first shot, a feature first observed on the Sauer 38H. A further function of the decocking lever is to rel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Springfield Armory P9
The CZ 75 is a semi-automatic pistol made by Czech firearm manufacturer ČZUB. First introduced in 1975, it is one of the original " wonder nines" and features a staggered-column magazine, all-steel construction, and a hammer forged barrel. It is widely distributed throughout the world and is the most common handgun in the Czech Republic. History Development of CZ 75 The armament industry was an important part of the interwar Czechoslovak economy and made up a large part of the country's exports (see, for example, Bren light machine gun, which was a modified version of the Czechoslovak ZB vz. 26). However following the 1948 communist coup d'état, all heavy industry was nationalized and was (at least officially) cut off from its Western export market behind the Iron Curtain. While most other Warsaw Pact countries became dependent on armaments imports from the Soviet Union, most of the Czechoslovak weaponry remained domestic (for example, the Czechoslovak army used the Vz. 58 ...

Psyclon Nine
Psyclon Nine is an American band formed in 2000 in San Francisco, CA, known for their unique blend of electronic, industrial metal. Originally, Psyclon Nine's music was Terror EBM with melancholic atmospheres and black metal style vocals. However, the band has since evolved a more industrial metal sound with black metal elements. Psyclon Nine's main music contributor is lead vocalist, lyricist, multi-instrumentalist, and producer Nero Bellum, who is the only remaining original member. In 2009, Psyclon Nine's fourth album ''We the Fallen'' was the band's first and only album to appear on the Billboard Charts. History Early days (1999–2003) Psyclon Nine began in 1999 when roommates, Marshall Goppert and Josef Heresy created an industrial metal music project called "Defkon Sodomy", influenced by bands like KMFDM and Ministry. The band only performed under that name twice before changing it to Psyclon Nine. The name was a malapropism of Zyklon B, the trade name of hydrogen c ...

P-9 Project
The P-9 Project was the codename given during World War II to the Manhattan Project's heavy water production program. The Cominco operation at Trail, British Columbia, was upgraded to produce heavy water. DuPont built three plants in the United States: at the Morgantown Ordnance Works, near Morgantown, West Virginia; at the Wabash River Ordnance Works, near Dana and Newport, Indiana; and at the Alabama Ordnance Works, near Childersburg and Sylacauga, Alabama. The American plants operated from 1943 until 1945. The Canadian plant at Trail continued in operation until 1956. Three nuclear reactors were built using the heavy water produced by the P-9 Project: Chicago Pile 3 at Argonne, and ZEEP and NRX at the Chalk River Laboratories in Canada. Origins Heavy water is a form of water that contains a larger than normal amount of the hydrogen isotope deuterium, also known as heavy hydrogen, rather than the common hydrogen-1 isotope that makes up most of the hydrogen in ordin ...
