3j Symbol
In quantum mechanics, the Wigner's 3-j symbols, also called 3''-jm'' symbols, are an alternative to Clebsch–Gordan coefficients for the purpose of adding angular momenta. While the two approaches address exactly the same physical problem, the 3-''j'' symbols do so more symmetrically. Mathematical relation to Clebsch–Gordan coefficients The 3-''j'' symbols are given in terms of the Clebsch–Gordan coefficients by : \begin j_1 & j_2 & j_3 \\ m_1 & m_2 & m_3 \end \equiv \frac \langle j_1 \, m_1 \, j_2 \, m_2 , j_3 \, (-m_3) \rangle. The ''j'' and ''m'' components are angular-momentum quantum numbers, i.e., every (and every corresponding ) is either a nonnegative integer or half-odd-integer. The exponent of the sign factor is always an integer, so it remains the same when transposed to the left, and the inverse relation follows upon making the substitution : : \langle j_1 \, m_1 \, j_2 \, m_2 , j_3 \, m_3 \rangle = (-1)^ \sqrt \begin j_1 & j_ ...

Zip (airline)
Zip was a Canadian low-cost carrier, discount airline headquartered in Hangar 101 at Calgary International Airport, Calgary, Alberta. It was launched by Air Canada as a no-frills subsidiary in September 2002. It operated a fleet of 12 Boeing 737 aircraft, each painted in a bright, neon color, neon colour (blue, fuchsia (color), fuchsia, green, and Orange (colour), orange) with a single class of service.

Jubba Airways
Jubba Airways is a Somali airline that operates domestic passenger and cargo flights within Somalia, as well as to destinations in the Middle East.

J-coupling
In nuclear chemistry and nuclear physics, ''J''-couplings (also called spin-spin coupling or indirect dipole–dipole coupling) are mediated through chemical bonds connecting two spins. It is an indirect interaction between two nuclear spins that arises from hyperfine interactions between the nuclei and local electrons. In NMR spectroscopy, ''J''-coupling contains information about relative bond distances and angles. Most importantly, ''J''-coupling provides information on the connectivity of chemical bonds. It is responsible for the often complex splitting of resonance lines in the NMR spectra of fairly simple molecules. ''J''-coupling is a frequency ''difference'' that is not affected by the strength of the magnetic field, so is always stated in Hz. Vector model and manifestations for chemical structure assignments The origin of ''J''-coupling can be visualized by a vector model for a simple molecule such as hydrogen fluoride (HF). In HF, the two nuclei have spin . Four st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Triple J
Triple J is an Australian government-funded national radio station founded in 1975 as a division of the Australian Broadcasting Corporation (ABC). It aims to appeal to young listeners of alternative music, and plays far more Australian content than commercial networks. The station was set up under the Gough Whitlam government, wanting to extend the appeal of the ABC to young Australians. Initially broadcasting as 2JJ or Double Jay from 19 January 1975, it stood apart from commercial stations with its lack of private advertising and its fringe music programming. Following a transition to FM in 1981, the station rebranded as 2JJJ or Triple J as it expanded regionally throughout the 1990s. Two spin-off digital stations were launched in the early 2010s: Double J aims to appeal to more mature audiences, and Triple J Unearthed plays only unsigned, local musicians. Despite declining ratings in their target 18–24-year-old demographic, Triple J maintains a strong podcast and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
