1G refers to the first generation of wireless cellular technology (mobile telecommunications). These are the analog telecommunications standards that were introduced in the 1980s and continued until being replaced by 2G digital telecommunications. The main difference between the two mobile cellular systems (1G and 2G), is that the radio signals used by 1G networks are analog, while 2G networks are digital.

Although both systems use digital signaling to connect the radio towers (which listen to the handsets) to the rest of the telephone system, the voice itself during a call is encoded to digital signals in 2G whereas 1G is only modulated to higher frequency, typically 150 MHz and up. The inherent advantages of digital technology over that of analog meant that 2G networks eventually replaced them almost everywhere.

One such standard is Nordic Mobile Telephone (NMT), used in Nordic countries, Switzerland, the Netherlands, Eastern Europe and Russia. Others include Advanced Mobile Phone System (AMPS) used in North America and Australia, TACS (Total Access Communications System) in the United Kingdom, C-450 in West Germany, Portugal and South Africa, Radiocom 2000 in France, TMA in Spain, and RTMI in Italy. In Japan there were multiple systems. Three standards, TZ-801, TZ-802, and TZ-803 were developed by NTT (Nippon Telegraph and Telephone Corporation), while a competing system operated by Daini Denden Planning, Inc. (DDI) used the Japan Total Access Communications System (JTACS) standard.

The antecedent to 1G technology is the mobile radio telephone.

Alfa Romeo Giulia TZ

The Alfa Romeo Giulia TZ (also known as the Alfa Romeo TZ or Tubolare Zagato) was a sports car and racing car manufactured by Alfa Romeo from 1963 to 1967. It replaced the Giulietta SZ. In 2011, the name was reduced from Giulia TZ to TZ in the new TZ3 model.

Calvi-class submarine

The Calvi class was a class of three submarines built by Oderno-Terni-Orlando in Genoa for the Royal Italian Navy (Italian: Regia Marina). The submarines were built in 1935, and all three served in the Mediterranean at the start of the Second World War. The boats were transferred to the BETASOM Atlantic submarine base at Bordeaux in August 1940. In December 1941 the boats were used for a rescue mission of 254 sailors from the sunken German auxiliary cruiser Atlantis. After Calvi had been sunk, Finzi and Tazzoli were selected for conversion to "transport submarines" in order to exchange rare or irreplaceable trade goods with Japan. Cargo capacity of 160 tons reduced reserve buoyancy from 20–25% to 3.5–6%; and armament was reduced to defensive machine guns.

FK Fotbal Třinec

FK Fotbal Třinec is a football club based in Třinec, Czech Republic. It plays in the Czech 2. Liga. It is sponsored by the Třinec Iron and Steel Works; in the past the club bore the name of the company.

The club's highest achievement was the presence in the Czechoslovak First League, where the club was present for six seasons in the 1960s and 1970s.

HMS Sanguine

HMS Sanguine was an S-class submarine of the Royal Navy, and part of the Third Group built of that class. She was built by Cammell Laird and launched on 15 February 1945. So far she has been the only ship of the Royal Navy to bear the name Sanguine.

Built as the Second World War was drawing to a close, she did not see much action. In 1953 she took part in the Fleet Review to celebrate the Coronation of Queen Elizabeth II.


The ICE 1 is the first batch-produced German high-speed train and one of six in the InterCityExpress family. Revenue service at speeds up to 250 km/h (155.3 mph) started in 1991. It was raised to 280 km/h (174.0 mph) in May 1995 and later reduced to 250 km/h (155.3 mph) again. Today, only a handful of ICE 1 services on the Nuremberg–Ingolstadt high-speed rail line reach 280 km/h (174.0 mph).

Trainsets consist of two power cars (Class 401) and up to 14 intermediate cars (Classes 801 to 804). Occasionally, power cars and intermediate cars of the ICE 2 are used as well (Classes 402, 805 to 808). Unlike later ICE generations, trainsets always operate as a whole train and units cannot be coupled in regular service.

One of the 60 trainsets (trainset 51) was destroyed in the Eschede train disaster. The others were refurbished between 2005 and 2008 and will remain in service for ten to fifteen additional years.

L 1159-16

L 1159-16 is a red dwarf in the northern constellation of Aries. With an apparent visual magnitude of 12.298, it is too faint to be seen by the naked eye, although it lies relatively close to the Sun at a distance of about 14.5 light-years (4.4 parsecs). It is a flare star, which means it can suddenly increase in brightness for short periods of time.

Mayan languages

The Mayan languages form a language family spoken in Mesoamerica and northern Central America. Mayan languages are spoken by at least 6 million Maya peoples, primarily in Guatemala, Mexico, Belize and Honduras. In 1996, Guatemala formally recognized 21 Mayan languages by name, and Mexico recognizes eight more within its territory.The Mayan language family is one of the best-documented and most studied in the Americas. Modern Mayan languages descend from the Proto-Mayan language, thought to have been spoken at least 5,000 years ago; it has been partially reconstructed using the comparative method. The proto-Mayan language diversified into at least six different branches: the Huastecan, Quichean, Yucatecan, Qanjobalan, Mamean and Chʼolan–Tzeltalan branches.

Mayan languages form part of the Mesoamerican language area, an area of linguistic convergence developed throughout millennia of interaction between the peoples of Mesoamerica. All Mayan languages display the basic diagnostic traits of this linguistic area. For example, all use relational nouns instead of prepositions to indicate spatial relationships. They also possess grammatical and typological features that set them apart from other languages of Mesoamerica, such as the use of ergativity in the grammatical treatment of verbs and their subjects and objects, specific inflectional categories on verbs, and a special word class of "positionals" which is typical of all Mayan languages.

During the pre-Columbian era of Mesoamerican history, some Mayan languages were written in the logo-syllabic Maya script. Its use was particularly widespread during the Classic period of Maya civilization (c. 250–900). The surviving corpus of over 10,000 known individual Maya inscriptions on buildings, monuments, pottery and bark-paper codices, combined with the rich postcolonial literature in Mayan languages written in the Latin script, provides a basis for the modern understanding of pre-Columbian history unparalleled in the Americas.

The TZ-45 was an Italian submachine gun produced in small numbers between 1944 and 1945, with an estimated 6,000 made.

TZ Cassiopeiae

TZ Cassiopeaie (TZ Cas, HIP 117763, SAO 20912) is a variable star in the constellation Cassiopeia with an apparent magnitude of around +9 to +10. It is approximately 8,000 light-years away from Earth. The star is a red supergiant star with a spectral type of M3 and a temperature below 4000 Kelvin.

TZ Cassiopeiae was reported as being variable by Williamina Fleming and published posthumously in 1911. It is a slow irregular variable star with a possible period of 3,100 days. It is over 60,000 times the luminosity of the Sun, and it is 645 to 800 times larger than the Sun. It is a member of the Cas OB5 stellar association, together with the nearby red supergiant PZ Cassiopeiae.The initial mass of TZ Cassiopeiae has been estimated from its position relative to theoretical stellar evolutionary tracks to be around 15 M☉.TZ Cas is losing mass through a powerful stellar wind at two millionths of a solar mass each year. It is unclear whether this is sufficient to cause the star to lose its atmosphere and become a blue supergiant before the core exhausts its fuel and collapses as a supernova. Either as a red or blue supergiant, or a Wolf-Rayet star, it will inevitably end its life violently in a supernova explosion when the core collapse occurs.


Tanzania (, Swahili: [tanzaˈni.a]) officially the United Republic of Tanzania (Swahili: Jamhuri ya Muungano wa Tanzania), is a country in eastern Africa within the African Great Lakes region. It borders Uganda to the north; Kenya to the northeast; Comoro Islands at the Indian Ocean to the east; Mozambique and Malawi to the south; Zambia to the southwest; and Rwanda, Burundi, and the Democratic Republic of the Congo to the west. Mount Kilimanjaro, Africa's highest mountain, is in north-eastern Tanzania.

The very first humans known as Pliocene lived in Tanzania 6 million years ago. The genus Australopithecus ranged all over Africa 4-2 million years ago; and the oldest remains of the Homo genus are found near Lake Olduvai. Following the rise of Homo erectus 1.8 million years ago, mankind spread all over the Old World, and later in the New World and Australia under the species Homo sapiens. Homo sapiens also overtook Africa and absorbed the older archaic species and subspecies of humanity. One of the oldest known ethnic groups still existing, the Hadzabe, appears to have originated in Tanzania, and their oral history recalls ancestors who were tall and were the first to use fire, medicine, and lived in caves, much like Homo erectus or Homo heidelbergensis who lived in the same region before them.

Later in the Stone and Bronze Age, prehistoric migrations into Tanzania included Southern Cushitic speakers who moved south from present-day Ethiopia; Eastern Cushitic people who moved into Tanzania from north of Lake Turkana about 2,000 and 4,000 years ago; and the Southern Nilotes, including the Datoog, who originated from the present-day South Sudan–Ethiopia border region between 2,900 and 2,400 years ago. These movements took place at about the same time as the settlement of the Mashariki Bantu from West Africa in the Lake Victoria and Lake Tanganyika areas. They subsequently migrated across the rest of Tanzania between 2,300 and 1,700 years ago.European colonialism began in mainland Tanzania during the late 19th century when Germany formed German East Africa, which gave way to British rule following World War I. The mainland was governed as Tanganyika, with the Zanzibar Archipelago remaining a separate colonial jurisdiction. Following their respective independence in 1961 and 1963, the two entities merged in April 1964 to form the United Republic of Tanzania.The United Nations estimated Tanzania's 2016 population at 55.57 million. The population is composed of several ethnic, linguistic, and religious groups. The sovereign state of Tanzania is a presidential constitutional republic and since 1996 its official capital city has been Dodoma where the president's office, the National Assembly, and some government ministries are located. Dar es Salaam, the former capital, retains most government offices and is the country's largest city, principal port, and leading commercial centre. Tanzania is a de facto one-party state with the democratic socialist Chama Cha Mapinduzi party in power.

Tanzania is mountainous and densely forested in the north-east, where Mount Kilimanjaro is located. Three of Africa's Great Lakes are partly within Tanzania. To the north and west lie Lake Victoria, Africa's largest lake, and Lake Tanganyika, the continent's deepest lake, known for its unique species of fish. To the south lies Lake Malawi. The eastern shore is hot and humid, with the Zanzibar Archipelago just offshore. The Menai Bay Conservation Area is Zanzibar's largest marine protected area. The Kalambo Falls, located on the Kalambo River at the Zambian border, is the second highest uninterrupted waterfall in Africa.Over 100 different languages are spoken in Tanzania, making it the most linguistically diverse country in East Africa. The country does not have a de jure official language, although the national language is Swahili. Swahili is used in parliamentary debate, in the lower courts, and as a medium of instruction in primary school. English is used in foreign trade, in diplomacy, in higher courts, and as a medium of instruction in secondary and higher education, although the Tanzanian government is planning to discontinue English as a language of instruction altogether. Approximately 10 percent of Tanzanians speak Swahili as a first language, and up to 90 percent speak it as a second language.

Time in Antarctica

Antarctica sits on every line of longitude, due to the South Pole being situated near the middle of the continent. Theoretically Antarctica would be located in all time zones; however, areas south of the Antarctic Circle experience extreme day-night cycles near the times of the June and December solstices, making it difficult to determine which time zone would be appropriate. For practical purposes time zones are usually based on territorial claims; however, many stations use the time of the country they are owned by or the time zone of their supply base (e.g. McMurdo Station and Amundsen–Scott South Pole Station use New Zealand time due to their main supply base being Christchurch, New Zealand). Nearby stations can have different time zones, due to their belonging to different countries. Many areas have no time zone since nothing is decided and there are not even any temporary settlements that have any clocks. They are simply labeled with UTC time.


Tioconazole is an antifungal medication of the imidazole class used to treat infections caused by a fungus or yeast. It is marketed under the brand names Trosyd and Gyno-Trosyd (Pfizer, now Johnson & Johnson). Tioconazole ointments serve to treat women's vaginal yeast infections. They are available in one day doses, as opposed to the 7-day treatments more common in use in the past.

Tioconazole topical (skin) preparations are also available for ringworm, jock itch, athlete's foot, and tinea versicolor or "sun fungus".

It was patented in 1975 and approved for medical use in 1982.

Tz database

The tz database is a collaborative compilation of information about the world's time zones, primarily intended for use with computer programs and operating systems. Paul Eggert is its current editor and maintainer, with the organizational backing of ICANN. The tz database is also known as tzdata, the zoneinfo database or IANA time zone database, and occasionally as the Olson database, referring to the founding contributor, Arthur David Olson.Its uniform naming convention for time zones, such as America/New_York and Europe/Paris, was designed by Paul Eggert. The database attempts to record historical time zones and all civil changes since 1970, the Unix time epoch. It also includes transitions such as daylight saving time, and also records leap seconds.The database, as well as some reference source code, is in the public domain. New editions of the database and code are published as changes warrant, usually several times per year.

Zastava CZ 99

The Zastava CZ 99 is a semi-automatic pistol produced by Zastava Arms. It was developed in 1989 to replace the M57 in the Yugoslavian Military and Police. The frame design was influenced by the SIG P226 albeit with some ambidextrous controls like the Walther P88 Compact. The CZ 99 is primarily chambered in 9×19mm Parabellum with a 15-round magazine.
