469705 ǂKá̦gára
469705 ǂKá̦gára (provisional designation ) is a trans-Neptunian object and binary system of the core Kuiper belt, located in the outermost region of the Solar System. It was discovered on 11 March 2005 by American astronomer Marc Buie at the Kitt Peak Observatory in Arizona. The primary body measures around in diameter. Its 120-kilometer (75-mile) companion ǃHãunu was discovered with the Hubble Space Telescope in 2009. The ǂKá̦gára–ǃHãunu system is currently undergoing mutual occultation and eclipsing events in which one body casts a shadow on or obstructs the view of the other as seen from Earth. Names The names ''ǂKá̦gára'' and ''ǃHãunu'' are from the mythology of the ǀXam people of South Africa. ǂKá̦gára (also rendered ǂKaʻgara) and his brother-in-law ǃHãunu fought an epic battle in the east using thunder and lightning, producing mountainous clouds and rain. The conflict was fought over ǂKá̦gára's returning his younger sister, ǃHãun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hubble Space Telescope
The Hubble Space Telescope (HST or Hubble) is a space telescope that was launched into low Earth orbit in 1990 and remains in operation. It was not the Orbiting Solar Observatory, first space telescope, but it is one of the largest and most versatile, renowned as a vital research tool and as a public relations boon for astronomy. The Hubble Space Telescope is named after astronomer Edwin Hubble and is one of NASA's Great Observatories program, Great Observatories. The Space Telescope Science Institute (STScI) selects Hubble's targets and processes the resulting data, while the Goddard Space Flight Center (GSFC) controls the spacecraft. Hubble features a mirror, and its five main instruments observe in the ultraviolet, visible spectrum, visible, and near-infrared regions of the electromagnetic spectrum. Hubble's orbit outside the distortion of atmosphere of Earth, Earth's atmosphere allows it to capture extremely high-resolution images with substantially lower background lig ...

ASCII
ASCII ( ), an acronym for American Standard Code for Information Interchange, is a character encoding standard for representing a particular set of 95 (English language focused) printable character, printable and 33 control character, control characters a total of 128 code points. The set of available punctuation had significant impact on the syntax of computer languages and text markup. ASCII hugely influenced the design of character sets used by modern computers; for example, the first 128 code points of Unicode are the same as ASCII. ASCII encodes each code-point as a value from 0 to 127 storable as a seven-bit integer. Ninety-five code-points are printable, including digits ''0'' to ''9'', lowercase letters ''a'' to ''z'', uppercase letters ''A'' to ''Z'', and commonly used punctuation symbols. For example, the letter is represented as 105 (decimal). Also, ASCII specifies 33 non-printing control codes which originated with ; most of which are now obsolete. The control cha ...

Pharyngealized
Pharyngealization is a secondary articulation of consonants or vowels by which the pharynx or epiglottis is constricted during the articulation of the sound. IPA symbols In the International Phonetic Alphabet, pharyngealization can be indicated by one of two methods: #A tilde or swung dash (IPA Number 428) is written through the base letter (typographic overstrike). It is the older and more generic symbol. It indicates velarization, uvularization or pharyngealization, as in , the guttural equivalent of . #The symbol (IPA Number 423) – a superscript variant of , the voiced pharyngeal approximant – is written after the base letter. It indicates specifically a pharyngealized consonant, as in , a pharyngealized . Computing codes Since Unicode 1.1, there have been two similar superscript characters: IPA () and Semiticist (). U+02E4 is formally a superscript (, = reversed glottal stop), and in the Unicode charts looks like a simple superscript , though in some fo ...

Diacritic
A diacritic (also diacritical mark, diacritical point, diacritical sign, or accent) is a glyph added to a letter or to a basic glyph. The term derives from the Ancient Greek (, "distinguishing"), from (, "to distinguish"). The word ''diacritic'' is a noun, though it is sometimes used in an attributive sense, whereas ''diacritical'' is only an adjective. Some diacritics, such as the acute , grave , and circumflex (all shown above an 'o'), are often called ''accents''. Diacritics may appear above or below a letter or in some other position such as within the letter or between two letters. The main use of diacritics in Latin script is to change the sound-values of the letters to which they are added. Historically, English has used the diaeresis diacritic to indicate the correct pronunciation of ambiguous words, such as "coöperate", without which the letter sequence could be misinterpreted to be pronounced . Other examples are the acute and grave accents, which can indica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Khoisan Languages
The Khoisan languages ( ; also Khoesan or Khoesaan) are a number of Languages of Africa, African languages once classified together, originally by Joseph Greenberg. Khoisan is defined as those languages that have click languages, click consonants and do not belong to other African language families. For much of the 20th century, they were thought to be Genetic relationship (linguistics), genealogically related to each other, but this is no longer accepted. They are now held to comprise three distinct language family, language families and two language isolates. All but two Khoisan languages are indigenous to southern Africa; these are classified into three language families. The Khoe languages, Khoe family appears to have migrated to southern Africa not long before the Bantu expansion. Ethnically, their speakers are the Khoekhoe and the San people, San (Bushmen). Two languages of eastern Africa, those of the Sandawe people, Sandawe and Hadza people, Hadza, were originally also cl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Click Consonants
Click consonants, or clicks, are speech sounds that occur as consonants in many languages of Southern Africa and in three languages of East Africa. Examples familiar to English-speakers are the '' tut-tut'' (British spelling) or '' tsk! tsk!'' (American spelling) used to express disapproval or pity (IPA ), the '' tchick!'' used to spur on a horse (IPA ), and the '' clip-clop!'' sound children make with their tongue to imitate a horse trotting (IPA ). However, these paralinguistic sounds in English are not full click consonants, as they only involve the front of the tongue, without the release of the back of the tongue that is required for clicks to combine with vowels and form syllables. Anatomically, clicks are obstruents articulated with two closures (points of contact) in the mouth, one forward and one at the back. The enclosed pocket of air is rarefied by a sucking action of the tongue (in technical terminology, clicks have a lingual ingressive airstream mechanism). The ...

Delayed Aspiration
Nasal clicks are click consonants pronounced with nasal airflow. All click types (alveolar , dental , lateral , palatal , retroflex , and labial ) have nasal variants, and these are attested in four or five phonations: voiced, voiceless, aspirated, murmured (breathy voiced), and—in the analysis of Miller (2011)—glottalized. Types of nasal clicks Modally voiced nasal clicks are ubiquitous: They are found in every language which has clicks as part of its regular sound inventory. This includes Damin, which has only nasal clicks, and Dahalo, which has only plain and glottalized nasal clicks. They are fully nasalized throughout, like the pulmonic nasal and . That is, you pronounce a uvular sound (like English ''ng'') with the back of your tongue, and make the click sound in the middle of it using the front of your tongue. They are typically transcribed something like ; in Khoekhoe, they are written , in Juǀʼhõa as , and in Zulu, Xhosa, Sandawe, and Naro as . s, often ...

Nasalization
In phonetics, nasalization (or nasalisation in British English) is the production of a sound while the velum is lowered, so that some air escapes through the nose during the production of the sound by the mouth. An archetypal nasal sound is . In the International Phonetic Alphabet, nasalization is indicated by printing a tilde diacritic above the symbol for the sound to be nasalized: is the nasalized equivalent of , and is the nasalized equivalent of . A subscript diacritic , called an or , is sometimes seen, especially when the vowel bears tone marks that would interfere with the superscript tilde. For example, are more legible in most fonts than . Nasal vowels Many languages have nasal vowels to different degrees, but only a minority of world languages around the world have nasal vowels as contrasting phonemes. That is the case, among others, of French, Portuguese, Hindustani, Nepali, Breton, Gheg Albanian, Hmong, Hokkien, Yoruba, and Cherokee. Those nasal vo ...

Pulmonic-contour Click
Pulmonic-contour clicks, also called sequential linguo-pulmonic consonants, are consonants that transition from a click to an ordinary pulmonic sound, or more precisely, have an audible delay between the front and rear release of the click. All click types (alveolar , dental , lateral , palatal , retroflex , and labial ) have linguo-pulmonic variants, which occur as both stops and affricates, and are attested in four phonations: tenuis, voiced, aspirated, and murmured (breathy voiced). At least a voiceless linguo-pulmonic affricate is attested from all Khoisan languages of southern Africa (the Khoe, Tuu, and Kx'a language families), as well as (reportedly) from the Bantu language Yeyi from the same area, but they are unattested elsewhere. Analysis Traditionally, contour clicks were believed to be uvular in their rear articulation, whereas non-contour clicks were thought to be velar. However, it is now known that all clicks are uvular, at least in the languages that have ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nǁng Language
Nǁng () or Nǁŋǃke, commonly known by the name of its only spoken dialect Nǀuu (), is a moribund language, moribund Tuu languages, Tuu language once spoken in South Africa. It is no longer spoken on a daily basis, as the speakers live in different villages. The ǀʼAuni language, ǀʼAuni name for the Nǀuu, ǂKhomani, is used by the South African government. As of June 2021, only one speaker of the Nǀuu dialect remains, the rest of the population having shifted to Khoekhoe language, Khoekhoe and Afrikaans. Classification and name Nǁng belongs to the Tuu languages, Tuu (Taa–ǃKwi) language family, with extinct ǂUngkue language, ǂUngkue being its closest relative and Taa language, Taa its closest living relative. The two recent dialects are a western/northwestern one, to which Nǀuu (Nǀhuki) is sometimes restricted, and a nameless eastern dialect from the area of Langeberg. As of 2010, most remaining speakers spoke Nǀuu dialect, and this was the name Nǁng appeared u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
