Television

Television is a telecommunication medium used for transmitting sound with moving images in monochrome (black-and-white), or in colour, and in two or three dimensions. It can refer to a television set, a television program, or the medium of television transmission. Television is a mass medium, for entertainment, education, news and advertising.

Television became available in crude experimental forms in the late 1920s. After World War II, an improved form became popular in the United States and Britain, and television sets became commonplace in homes, businesses, and institutions. During the 1950s, television was the primary medium for influencing public opinion. In the mid-1960s, color broadcasting was introduced in the US and most other developed countries. The availability of storage media such as VHS tape (1976), DVDs (1997), and high-definition Blu-ray Discs (2006) enabled viewers to watch recorded material such as movies. At the end of the first decade of the 2000s, digital television transmissions greatly increased in popularity. Another development was the move from standard-definition television (SDTV) (576i, with 576 interlaced lines of resolution and 480i) to high-definition television (HDTV), which provides a resolution that is substantially higher. HDTV may be transmitted in various formats: 1080p, 1080i and 720p. Since 2010, with the invention of smart television, Internet television has increased the availability of television programs and movies via the Internet through services such as Netflix, iPlayer, Hulu, Roku and Chromecast.

Töv Province

Töv (Mongolian: Төв, lit. "central") is one of the 21 aimags (provinces) of Mongolia. The national capital Ulaanbaatar is located roughly at its center, but the city itself is administrated as an independent municipality.

Geography

The Aimag includes the western part of the Khentii Mountains, the mountains around the capital, as well as rolling steppe in the south and west. The most interesting body of water is the Tuul River, which crosses Ulaanbaatar and later joins the Orkhon River.

Population

The Töv aimag is populated primarily by Halh Mongols, major minority group of Kazakhs declined at intercensal period of massive out migration to the Kazakhstan, rest of minority groups grew off in migrations.

Traffic

The central traffic node is the enclave Ulaanbaatar. The city includes the largest station of the Trans-Mongolian Railway and the Chinggis Khaan International Airport. A small airport with an unpaved runway also exists in the aimag capital Zuunmod.

Culture

Manzushir Monastery is located near Zuunmod in the Bogd Khan Mountain national park. It was founded in 1733 and used to be the home of 20 temples and 300 monks. Most of it was destroyed by the communists, yet the last temple was restored after democratisation and hosts a small museum today.

Lockheed T2V SeaStar

The Lockheed T2V SeaStar, later called the T-1 SeaStar, was a turbojet trainer aircraft for the U.S. Navy that entered service in May 1957. It was developed from the Lockheed T-33 and powered by one Allison J33 engine.

Design and development

Starting in 1949, the U.S. Navy used the Lockheed T-33 for land-based jet aircraft training. The T-33 was a derivative of the Lockheed P-80 fighter and was first named TO-2, then TV-2 in Navy service. However, the TV-2 was not suitable for operation from aircraft carriers. The persisting need for a carrier-compatible trainer led to a further, more advanced design development of the P-80/T-33 family, which came into being with the Lockheed designation L-245 and US Navy designation T2V. Lockheed's demonstrator L-245 first flew on 16 December 1953 and production deliveries to the US Navy began in 1956.

Compared to the TV-2, the T2V was almost totally re-engineered for carrier landings and at-sea operations with a redesigned tail, naval standard avionics, a strengthened undercarriage (with catapult fittings) and lower fuselage (with a retractable arrestor hook), and power-operated leading-edge flaps (to increase lift at low speeds) to allow carrier launches and recoveries, and an elevated rear (instructor's) seat for improved instructor vision, among other changes. Unlike other P-80 derivatives, the T2V could withstand the shock of landing on a pitching carrier deck and had a much higher ability to withstand sea water-related aircraft wear from higher humidity and salt exposure.

T-28

The T-28 was a Soviet multi-turreted tank that was among the world's first medium tanks. The prototype was completed in 1931, and production began in late 1932. It was an infantry support tank intended to break through fortified defences. The T-28 was designed to complement the heavier T-35 (also multi-turreted), with which it shared turret designs. The type did not have great success in combat, but it played an important role as a development project for Soviet tank designers. A series of new ideas and solutions that were tried out on the T-28 were later incorporated in future models.

Design history

The T-28 was in many ways similar to the British Vickers A1E1 Independent tank, which greatly influenced tank design in the period between the wars, even though only a single prototype was manufactured in 1926. The Kirov Factory in Leningrad began manufacturing a tank that was based on the design of the British Independent in 1932. The T-28 tank was officially approved on 11 August 1933. The T-28 had one large turret with a 76.2 mm gun and two smaller turrets with 7.62 mm machine guns. A total of 503 T-28 tanks were manufactured over the eight-year period from 1933 to 1941.

Technischer Überwachungsverein

TÜVs (German pronunciation: [ˈtʏf]; short for German: Technischer Überwachungsverein, English: Technical Inspection Association) are German organizations that work to validate the safety of products of all kinds to protect humans and the environment against hazards. As independent consultants, they examine plants, motor vehicles, energy installations, amusement rides, devices and products (e.g. consumer goods) which require monitoring. The many subsidiaries of the TÜVs can also act as project developers for energy and traffic concepts, as problem solvers in environmental protection, and as certification bodies. Many of the TÜV organizations also provide certification for various international standards, such as ISO9001:2008 (quality management system) and ISO/TS16949 (automotive quality management system).

Trademark

The sign “TÜV” is protected by numerous domestic and foreign trademark registrations and applications consisting of the sign “TÜV”.

History

The TÜVs as a group became part of the German economy about 130 years ago, as part of the public and workplace safety initiatives of the time. To increase the safety of their equipment, steam engine and boiler owners founded regional "Dampfkessel-Überwachungs- und Revisions-Vereine" (DÜV) (steam boiler supervision and revision associations) as self-help organizations to independently supervise their boilers. Their success in preventing accidents was such that in 1871 membership in such an association relieved an owner from government inspections of their boilers.
