Beechcraft U-21 Ute
The Beechcraft King Air is a line of American utility aircraft produced by Beechcraft. The King Air line comprises a number of twin-turboprop models that have been divided into two families. The Model 90 and 100 series developed in the 1960s are known as King Airs, while the later T-tail Model 200 and 300 series were originally marketed as Super King Airs, with the name "Super" being dropped by Beechcraft in 1996 (although it is still often used to differentiate the 200 and 300 series King Airs from their smaller stablemates). The King Air was the first aircraft in its class and was produced continuously from 1964 to 2021. It outsold all of its turboprop competitors combined. It has recently faced competition from jet aircraft such as the Embraer Phenom 100, Honda HA-420 HondaJet and Cessna Citation Mustang; as well as from newer turboprop aircraft including the Piaggio P180 Avanti, and single-engine Piper Malibu Meridian, Pilatus PC-12, and Socata TBM.

Great Rhombihexahedron
In geometry, the great rhombihexahedron (or great rhombicube) is a nonconvex uniform polyhedron, indexed as U21. It has 18 faces (12 squares and 6 octagrams), 48 edges, and 24 vertices. Its dual is the great rhombihexacron. Its vertex figure is a crossed quadrilateral. Orthogonal projections Gallery Related polyhedra It shares the vertex arrangement with the convex truncated cube. It additionally shares its edge arrangement with the nonconvex great rhombicuboctahedron (having 12 square faces in common), and with the great cubicuboctahedron (having the octagrammic faces in common). It may be constructed as the exclusive or (blend) of three octagrammic prisms. Similarly, the small rhombihexahedron may be constructed as the exclusive or of three octagonal prisms. Great rhombihexacron The great rhombihexacron is a nonconvex isohedral polyhedron. It is the dual of the uniform great rhombihexahedron (U21). It has 24 identical bow-tie-shaped faces, 18 vertices, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Small Nucleolar RNA SNORD21
In molecular biology, U21 is a member of the C/D class of snoRNA which contain the C (UGAUGA) and D (CUGA) box motifs. U21 is encoded within an intron of the gene for ribosomal protein L5 in mammals, but within introns of the ADP ribosylation factor gene in Drosophila. U21 snoRNA has a 13 nucleotide region of complementarity with an invariant region of eukaryotic 28S ribosomal RNA Ribosomal ribonucleic acid (rRNA) is a type of non-coding RNA which is the primary component of ribosomes, essential to all cells. rRNA is a ribozyme which carries out protein synthesis in ribosomes.

Universitas 21
Universitas 21 (U21) is an international network of research-intensive universities. Founded in Melbourne, Australia in 1997 with 11 members, it has grown to include twenty-eight member universities in nineteen countries and territories. The universities collaborate on student experience, researcher engagement and educational innovation. It offers various student competitions including the Three Minute Thesis (3MT), the U21/PwC Innovation Challenge and the RISE (Real Impact on Society and Environment) Showcase. Since 2012, Universitas 21 has commissioned the "U21 Ranking of National Higher Education Systems". Produced by researchers at the University of Melbourne, this ranking aims to show which countries create a "strong environment" that allows universities to contribute to growth, provide a high-quality student experience and help institutions compete globally. It evaluates the standing of national higher education systems by providing rankings in four broad areas: resources, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
