Tatawin
Tataouine ( ber, Tiṭṭawin; ar, تطاوين) is a city in southern Tunisia. It is the capital of the Tataouine Governorate. The below-ground "cave dwellings" of the native Berber population, designed for coolness and protection, render the city and the area around it a tourist and film makers' attraction. Etymology The name means 'eyes' and 'water springs' in the Berber language. It is sometimes transliterated in European languages as ''Tatahouine'', ''Tatahouïne'', ''Tatawin'' or ''Tatooine''. The names "Tataouine", "Tatahouine" and "Foum Tatahouine" all appeared in the postcards portraying the city in the 1920s. The city used to be called (), alternatively spelled , , , or , which means 'mouth of the springs'. History From 1892 to 1951, Tataouine was the garrison town of the French penal military unit known as the "Battalion of Light Infantry of Africa". After the French established the town, a mosque (built in 1898) and homes were built in Tataouine. On June 27, 19 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flag Of Tunisia
The flag of Tunisia is a rectangular panel of red color with an aspect ratio of 2:3. In the center of the cloth in a white circle is placed a red crescent, surrounding a red five-pointed star on three sides. Bey Tunisia Hussein II decided to create a flag for Tunisia, close in appearance to the modern one, after the Battle of Navarino on 20 October 1827; in 1831 he was officially approved. In this form, the flag existed during the French protectorate, and on 1 June 1959, it was proclaimed the state flag of the Republic of Tunisia (in accordance with the country's constitution). On 30 June 1999, the proportions and design of the flag were clarified by a special law; the general appearance of the flag remained virtually unchanged. The crescent and star depicted on the flag of Tunisia are traditional symbols of Islam, and are also considered symbols of good luck. History Previous flags Until the mid-18th century, the design and significance of maritime flags flying on ships i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Enstatite
Enstatite is a mineral; the magnesium endmember of the pyroxene silicate mineral series enstatite (MgSiO3) – ferrosilite (FeSiO3). The magnesium rich members of the solid solution series are common rock-forming minerals found in igneous and metamorphic rocks. The intermediate composition, , has historically been known as hypersthene, although this name has been formally abandoned and replaced by orthopyroxene. When determined petrographically or chemically the composition is given as relative proportions of enstatite (En) and ferrosilite (Fs) (e.g., En80Fs20). Polymorphs and varieties Most natural crystals are orthorhombic (space group P''bca'') although three polymorphs are known. The high temperature, low pressure polymorphs are protoenstatite and protoferrosilite (also orthorhombic, space group P''bcn'') while the low temperature forms, clinoenstatite and clinoferrosilite, are monoclinic (space group P2''1/c''). Weathered enstatite with a small amount of iron takes on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sauropoda
Sauropoda (), whose members are known as sauropods (; from '' sauro-'' + '' -pod'', 'lizard-footed'), is a clade of saurischian ('lizard-hipped') dinosaurs. Sauropods had very long necks, long tails, small heads (relative to the rest of their body), and four thick, pillar-like legs. They are notable for the enormous sizes attained by some species, and the group includes the largest animals to have ever lived on land. Well-known genera include ''Brachiosaurus'', ''Diplodocus'', ''Apatosaurus'' and ''Brontosaurus''. The oldest known unequivocal sauropod dinosaurs are known from the Early Jurassic. ''Isanosaurus'' and ''Antetonitrus'' were originally described as Triassic sauropods, but their age, and in the case of ''Antetonitrus'' also its sauropod status, were subsequently questioned. Sauropod-like sauropodomorph tracks from the Fleming Fjord Formation (Greenland) might, however, indicate the occurrence of the group in the Late Triassic. By the Late Jurassic (150 million yea ...

Tataouinea
''Tataouinea'' is an extinct genus of sauropod dinosaur in the subfamily Rebbachisaurinae of Rebbachisauridae which lived in the Early Cretaceous of Tunisia. Only one species, ''T. hannibalis'', is known. Discovery and naming The first known elements of the holotype were discovered in the Aïn el Guettar Formation in 2011 by Aldo Luigi Bacchetta, but he was unable to excavate the specimen until 2012. The remains were subsequently studied by Federico Fanti, Andrea Cau, Mohsen Hassine and Michela Contessi. The genus was named in 2013. The name refers to the Tataouine Governatorate, Tunisia, and Hannibal. In 2015 more material of the holotype specimen was uncovered after the initial description were analysed. These included additional tail vertebrae. Description Its bones were extensively pneumatic, providing strong support for the theory that sauropods had birdlike respiratory systems. Key characteristics of its vertebral morphology show that ''Tatouinea'' was a rebbac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Allan Hills 84001
Allan Hills 84001 (ALH84001) is a fragment of a Martian meteorite that was found in the Allan Hills in Antarctica on December 27, 1984, by a team of American meteorite hunters from the ANSMET project. Like other members of the shergottite–nakhlite–chassignite (SNC) group of meteorites, ALH84001 is thought to have originated on Mars. However, it does not fit into any of the previously discovered SNC groups. Its mass upon discovery was . In 1996, a group of scientists found features in the likeness of microscopic fossils of bacteria in the meteorite, suggesting that these organisms also originated on Mars. The claims immediately made headlines worldwide, culminating in then-U.S. president Bill Clinton giving a speech about the potential discovery. These claims were controversial from the beginning, and the wider scientific community ultimately rejected the hypothesis once all the unusual features in the meteorite had been explained without requiring life to be present.

Microbial Cyst
A microbial cyst is a resting or dormant stage of a microorganism, usually a bacterium or a protist or rarely an invertebrate animal, that helps the organism to survive in unfavorable environmental conditions. It can be thought of as a state of suspended animation in which the metabolic processes of the cell are slowed and the cell ceases all activities like feeding and locomotion. Encystment, the formation of the cyst, also helps the microbe to disperse easily, from one host to another or to a more favorable environment. When the encysted microbe reaches an environment favorable to its growth and survival, the cyst wall breaks down by a process known as excystation. In excystment, the exact stimulus is unknown for most protists. Unfavorable environmental conditions such as lack of nutrients or oxygen, extreme temperatures, lack of moisture and presence of toxic chemicals, which are not conducive for the growth of the microbeEugene W. Nester, Denise G. Anderson, C. Evans Roberts ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
4 Vesta
Vesta (minor-planet designation: 4 Vesta) is one of the largest objects in the asteroid belt, with a mean diameter of . It was discovered by the German astronomer Heinrich Wilhelm Matthias Olbers on 29 March 1807 and is named after Vesta, the virgin goddess of home and hearth from Roman mythology. Vesta is thought to be the second-largest asteroid, both by mass and by volume, after the dwarf planet Ceres, though in volume it overlaps with the uncertainty in the measurements of 2 Pallas.Marsset, M., Brož, M., Vernazza, P. et al.

Nat Astron 4, 569–576 (2020). https://doi.org/10.1038/s41550-019-1007-5 Measurements give it a nominal volume only slightly larger than that of Pallas (about 5% greater, which is the magnitude of the uncertainties in measurement), but it is 25% to 30% more massive. It constitutes an estimated 9% of the mass of the asteroid belt. Vesta is the only known remaining rocky protoplanet (with a ...

Diogenite
Diogenites are a group of the HED meteorite clan, a type of achondritic stony meteorites. Origin and composition Diogenites are currently believed to originate from deep within the crust of the asteroid 4 Vesta, and as such are part of the HED meteorite clan. There are about 40 distinct members known. Diogenites are composed of igneous rocks of plutonic origin, having solidified slowly enough deep within Vesta's crust to form crystals which are larger than in the eucrites. These crystals are primarily magnesium-rich orthopyroxene, with small amounts of plagioclase and olivine. Name Diogenites are named for Diogenes of Apollonia, an ancient Greek philosopher who was the first to suggest an outer space origin for meteorites.

East Zenati Languages
The East Zenati languages (Blench, 2006) or Tunisian and Zuwara (Kossmann, 2013) are a group of the Zenati languages, Zenati Berber dialects spoken in Tunisia and Libya. Maarten Kossmann considers the easternmost varieties of Zenati dialects as transitional to Eastern Berber languages, Eastern Berber, but they are quite different from the neighboring Nafusi language, Nafusi. According to Kossmann, the dialect cluster of Tunisian Berber and Zuwara is consisting of the varieties spoken in mainland Tunisia (Sened language, Sened (extinct), Matmata Berber, Matmata and Tataouine Berber, Tataouine), Jerba language, Jerba and Zuwara language, Zuwara, but not Nafusi language, Nafusi which is considered a dialect of Eastern Berber languages, Eastern Berber.M.

ISIL
An Islamic state is a state that has a form of government based on Islamic law (sharia). As a term, it has been used to describe various historical polities and theories of governance in the Islamic world. As a translation of the Arabic term ''dawlah islāmiyyah'' ( ar, دولة إسلامية) it refers to a modern notion associated with political Islam (Islamism). Notable examples of historical Islamic states include the State of Medina, established by the Islamic prophet Muhammad, and the Arab Caliphate which continued under his successors and the Umayyads. The concept of the modern Islamic state has been articulated and promoted by ideologues such as Sayyid Rashid Rida, Mohammed Omar, Abul A'la Maududi, Ayatollah Ruhollah Khomeini, Israr Ahmed, Sayyid Qutb and Hassan al-Banna. Implementation of Islamic law plays an important role in modern theories of the Islamic state, as it did in classical Islamic political theories. However, most of the modern theories also make use ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
