Pentagrammic prism. In geometry, the pentagrammic prism is one of an infinite set of nonconvex prisms formed by square sides and two regular star polygon caps, in this case two pentagrams . It is a special case of a right prism with a pentagram as base, which in general has rectangular non-base faces. Topologically it is the same as a convex ...
British Museum. [3] The Rassam cylinder is a cuneiform cylinder, forming a prism with ten faces, written by Neo-Assyrian king Ashurbanipal in 643 BCE. The 7th century BCE cylinder was discovered in the North Palace of Nineveh by Hormuzd Rassam in 1854, hence its name. It is located in the British Museum.
Basis Nord. Basis Nord ("Base North") was a secret naval base of Nazi Germany 's Kriegsmarine in Zapadnaya Litsa, west of Murmansk provided by the Soviet Union. The base was part of a partnership that developed between Germany and the Soviet Union following German-Soviet Non-Aggression treaty of 1939, along with a broad economic agreement of 1940 .
Base (group theory) Let be a finite permutation group acting on a set . A sequence. of k distinct elements of is a base for G if the only element of which fixes every pointwise is the identity element of . [1] Bases and strong generating sets are concepts of importance in computational group theory. A base and a strong generating set (together ...
Source: DAFIF [1] [2] Karshi-Khanabad (or K2) is an air base in southeastern Uzbekistan, just east of Karshi. It is home to the 60th Separate Mixed Aviation Brigade of the Uzbek Air Force . The airport is 1,365 feet (416 m) above mean sea level. It has one runway designated 07/25 with a concrete surface measuring 8,196 by 131 feet (2,498 m × ...
Triangular bipyramid. In geometry, a triangular prism or trigonal prism [1] is a prism with 2 triangular bases. If the edges pair with each triangle's vertex and if they are perpendicular to the base, it is a right triangular prism. A right triangular prism may be both semiregular and uniform . The triangular prism can be used in constructing ...
Prism spectrometer. A prism spectrometer is an optical spectrometer which uses a dispersive prism as its dispersive element. The prism refracts light into its different colors ( wavelengths ). The dispersion occurs because the angle of refraction is dependent on the refractive index of the prism's material, which in turn is slightly dependent ...
Prism is the debut album by Canadian rock band Prism, [2] released in May 1977 on the Canadian record label GRT. It was produced primarily by Bruce Fairbairn, and the majority of songs were written by Jim Vallance (who also served as co-producer on three tracks).
