Longitude of the ascending node

The longitude of the ascending node is one of the orbital elements used to specify the orbit of an object in space. It is the angle from a reference direction, called the origin of longitude, to the direction of the ascending node, measured in a reference plane; the ascending node is the point where the orbit of the object passes through the plane of reference, as seen in the adjacent image. Used reference planes and origins of longitude include: For a geocentric orbit, Earth's equatorial plane as the reference plane, the First Point of Aries as the origin of longitude. In this case, the longitude is called the right ascension of the ascending node, or RAAN; the angle is measured eastwards from the First Point of Aries to the node. For a heliocentric orbit, the ecliptic as the reference plane, the First Point of Aries as the origin of longitude; the angle is measured counterclockwise from the First Point of Aries to the node. For an orbit outside the Solar System, the plane tangent to the celestial sphere at the point of interest as the reference plane, north, i.e. the perpendicular projection of the direction from the observer to the North Celestial Pole onto the plane of the sky, as the origin of longitude.

The angle is measured eastwards from north to the node. pp. 40, 72, 137. 17. In the case of a binary star known only from visual observations, it is not possible to tell which node is ascending and, descending. In this case the orbital parameter, recorded is the longitude of the node, Ω, the longitude of whichever node has a longitude between 0 and 180 degrees. Chap. 17. In astrodynamics, the longitude of the ascending node can be calculated from the specific relative angular momentum vector h as follows: n = k × h = Ω = { arccos ⁡ n x | n |, n y ≥ 0. Here, n=<nx, ny, nz> is a vector pointing towards the ascending node. The reference plane is assumed to be the xy-plane, the origin of longitude is taken to be the positive x-axis. K is the unit vector, the normal vector to the xy reference plane. For non-inclined orbits, Ω is undefined. For computation it is by convention, set equal to zero. Equinox Kepler orbits Orbital node Perturbation of the orbital plane can cause precession of the ascending node

2015 Men's Fistball World Championships

The 14th Men’s World Fistball Championships was held from the 14th to 22 November 2015 in Calamuchita, Córdoba in Argentina. It was the second time the Men's Fistball World Championships have been held in Argentina, having previously been held in Buenos Aires in 1986; the tournament was held in four settlements in Córdoba Province, three of them are located in Calamuchita: Villa General Belgrano, Santa Rosa de Calamuchita and Embalse. The fourth venue was La Cumbrecita, in Santa María Department. At the Fistball World Championships in 2015, a record 15 teams have committed to take part in the competition, increase on the 12 teams that competed at the last World Championships in 2011. Australia are expected to compete for the first time in its short history, marking the first time the Oceania region has been represented in fistball at the World Championships. Competing for the first time will be South Africa, becoming the second African team to compete. Two new Asian region teams will take part for the first time, with India and Pakistan committed to sending teams to the tournament.

Colombia will be the fifth team making its inaugural entry, becoming the fourth South American team represented. Germany will be defending their title as World Champion, will be joined by 9 other returning teams. Serbia and Japan are the only two teams not returning from the 2011 tournament; these teams have provisionally reported for the World Cup in Argentina: Official Website for 2015 Fistball World Championships

Kolkata Light Rail Transit

Kolkata Light Rail Transit is a mass rapid transit system proposed for the city of Kolkata in India. The Government of West Bengal and SREI Infrastructure Finance signed a memorandum of understanding to set up the light rail transit system. A special purpose vehicle, Kolkata Mass Rapid Transit Pvt Ltd has been formed to execute this Rs.6000 crore project. April 2002: The Master Plan for Kolkata Metropolitan Area for 2025 was submitted for the approval by the Metropolitan Planning Committee, it was proposed to be executed soon after securing agreement from the Chief Minister of West Bengal, Buddhadeb Bhattacharjee. It was suggested in the feasibility report that it will work well as an intermediate system for some selected corridors; the search for funding started and it did not sound much in public.2004: The Kolkata government wanted assistance from the central government which agreed to provide assistance for one major transit system project. Bhattacharjee chose LRTS over the East-West Metro corridor for the assistance and asked the state transport secretary to prepare a revised feasibility study.

April 2005: The feasibility study by CES termed it as EMRTS and proposed three corridors, all terminating at Esplanade. The rolling stock they proposed was high speed trams. February 2009: The LRTS project was listed under JNNURM, it was to be jointly executed by SREI and the Czech-based AMEX Corporation on a Build-Operate-Transfer basis. It was proposed to make the LRTS station at Barrackpore a terminal point connecting it with the main line station. Mr. Hemant Kanoria and Managing Director of Srei Infrastructure Limited signed an MOU with the Government of West Bengal to execute this project along with their consortium partners. Corridor 1: Joka — Esplanade Corridor 2: Esplanade — Barrackpore

Fredrik Pacius

Fredrik Pacius was a German Finnish composer and conductor who lived most of his life in Finland. He has been called the "Father of Finnish music". Pacius was born in Hamburg, he was appointed music teacher at the University of Helsinki in 1834. In Helsinki he founded a musical society, the student choir Akademiska Sångföreningen and an orchestra. In 1848 Pacius wrote the music to the poem "Vårt land" by Johan Ludvig Runeberg, to become Finland's national anthem. Pacius’s music was used for the Estonian national anthem "Mu isamaa, mu õnn ja rõõm" and the Livonian ethnic anthem "Min izāmō, min sindimō". In 1852 he composed Kung Karls jakt, the first Finnish opera, with a libretto in the style of Romantic nationalism, like the national anthem designed to convince Finland's grand duke of the total loyalty of his subjects in Finland; the libretto was written by the author and historian Zacharias Topelius in close collaboration with the composer. His compositions include a violin concerto, a symphony, a string quartet and several other operas.

Pacius died in Helsinki, aged 81.
