Timur[b] or Tamerlane[c] (8 April 1336[7] – 17–19 February 1405) was a Turco-Mongol conqueror who founded the Timurid Empire in and around modern-day Afghanistan, Iran, and Central Asia, becoming the first ruler of the Timurid dynasty. An undefeated commander, he is widely regarded as one of the greatest military leaders and tacticians in history, as well as one of the most brutal and deadly.[8][9][10] Timur is also considered a great patron of art and architecture as he interacted with intellectuals such as Ibn Khaldun, Hafez, and Hafiz-i Abru and his reign introduced the Timurid Renaissance.[11]

The Battle of Dandanaqan (Persian: نبرد دندانقان) was fought in 1040 between the Seljuq Turkmens and the Ghaznavid Empire near the city of Merv (now in Turkmenistan).[6][7] The battle ended with a decisive Seljuq victory, which subsequently brought down the Ghaznavid domination in Greater Khorasan.[1]

In the 8th century, they formed a tribal confederation conventionally named the Oghuz Yabgu State in Central Asia. Today, much of the populations of Turkey, Azerbaijan and Turkmenistan are descendants of Oghuz Turks.

The term Oghuz was gradually supplanted by the terms Turkmen and Turcoman (Ottoman Turkish: تركمن, romanized: Türkmen or Türkmân) by 13th century.[5]

The Oghuz Turks (Middle Turkic: ٱغُز, romanized: Oγuz) were a western Turkic people who spoke the Oghuz branch of the Turkic language family.[3]

Abū Isḥāq Muḥammad ibn al-Wāthiq (Arabic: أبو إسحاق محمد بن هارون الواثق‎; c. 833 – 21 June 870), better known by his regnal name al-Muhtadī bi-'llāh (Arabic: المهتدي بالله, "Guided by God"), was the Caliph of the Abbasid Caliphate from July 869 to June 870, during the "Anarchy at Samarra".

During the Arab conquest of Persia, the term became a racial pejorative.[3] In many languages, including Persian, Turkish, Urdu–Hindi, Azerbaijani, Bengali, Kurdish, Gujarati, Malay, Punjabi, and Swahili, Ajam and Ajami refer to Iran and Iranians respectively.

Ajam (Arabic: عجم, romanized: ʿajam) is an Arabic word meaning mute. It generally refers to someone whose mother tongue is not Arabic,[1] as well as non-Arabs.[2]

The Kharijites,[a] also called al-Shurat,[b] were an Islamic sect which emerged during the First Fitna (656–661).

After Muhammad's death, this institution was adapted by the Umayyad dynasty to incorporate new converts to Islam into Arab-Muslim society and the word mawali gained currency as an appellation for converted non-Arab Muslims in the early Islamic caliphates.

In the Quran and hadiths it is used in a number of senses, including 'Lord', 'guardian', and 'trustee'.[1]

Before the Islamic prophet Muhammad, the term originally applied to any form of tribal association.[2]

Mawlā (Arabic: مَوْلَى, plural mawālī مَوَالِي), is a polysemous Arabic word, whose meaning varied in different periods and contexts.[1]

Shu'ubiyya (Arabic: الشعوبية) was a literary-political movement which opposed the privileged status of Arabs within the Muslim community and the Arabization campaigns particularly by the Ummayads.[1] The vast majority of the Shu'ubis were Persian.[2][3]

The Umayyad dynasty (Arabic: بَنُو أُمَيَّةَ, romanized: Banū Umayya, lit. 'Sons of Umayya') or Umayyads (Arabic: الأمويون, romanized: al-Umawiyyūn) was an Arab clan within the Quraysh tribe who were the ruling family of the Caliphate between 661 and 750 and later of al-Andalus between 756 and 1031.

Monsters and villains depicted in many horror films have often had physical or mental disabilities. These evolved from being sympathetic depictions of disabled characters in early monster films such as Frankenstein, to presentations of disabled people as "bloodthirsty and terrifying" in slasher films of the 1970s and 1980s.[3] Horror films have sometimes attracted criticism for their depictions of disability[3][4][5] or have been described as ableist.[6] Some films have been accused of reflecting eugenicist views held by the society of their time.[7][1] Tropes of characters "overcoming" disability, or of disability granting special powers, have been described as harmful.[8]

Various modern figures such as the chair of the Federal Reserve in the United States, the prime minister in parliamentary systems, the president of the Swiss Confederation, the chief justice of the United States, the chief justice of the Philippines, the archbishop of Canterbury of the Anglican Communion and the ecumenical patriarch of Constantinople of the Eastern Orthodox Church fall under both senses: bearing higher status and various additional powers while remaining still merely equal to their peers in important senses.

Primus inter pares is a Latin phrase meaning first among equals.[a]

After the fall of the Republic, Roman emperors initially referred to themselves only as princeps despite having enormous power.

Historically, the princeps senatus of the Roman Senate was such a figure and initially bore only the distinction that he was allowed to speak first during debate

Spartacus (Greek: Σπάρτακος, translit. Spártakos; Latin: Spartacus; c. 103–71 BC) was a Thracian gladiator (Thraex) who, along with Crixus, Gannicus, Castus, and Oenomaus, was one of the escaped slave leaders in the Third Servile War, a major slave uprising against the Roman Republic.

The Getae (/ˈdʒiːtiː, ˈɡiːtiː/ JEE-tee, GHEE-tee) or Gets (/dʒɛts, ɡɛts/ JETS, GHETS; Ancient Greek: Γέται, singular Γέτης) were a Thracian-related[1] tribe that once inhabited the regions to either side of the Lower Danube, in what is today northern Bulgaria and southern Romania.

If this is true it refers not to its capture in the Second Punic War (211 BC), but to its submission to Rome in 338 BC. This places the date of foundation at about 600 BC, while Etruscan power was at its highest.[3]

The name of Capua comes from the Etruscan Capeva.[2] The meaning is 'City of Marshes'. Its foundation is attributed by Cato the Elder to the Etruscans, and the date given as about 260 years before it was "taken" by Rome

Banu (بنو) is Arabic for "the children of" or "descendants of" and appears before the name of a tribal progenitor.

According to a 17th century account, the Andalusian inventor Abbas ibn Firnas makes a tower jump in Córdoba. He wraps himself with vulture feathers and attaches two wings to his arms. The alleged attempt to fly is not recorded in earlier sources and is ultimately unsuccessful, but the garment slows his fall enough that he only sustains minor injuries.

Delusional disorder, traditionally synonymous with paranoia, is a mental illness in which a person has delusions, but with no accompanying prominent hallucinations, thought disorder, mood disorder, or significant flattening of affect.[7][8] Delusions are a specific symptom of psychosis. Delusions can be bizarre or non-bizarre in content;[8] non-bizarre delusions are fixed false beliefs that involve situations that could occur in real life, such as being harmed

History[edit] Glenford J. Myers initially introduced the separation of debugging from testing in 1979.[14] Although his attention was on breakage testing ("A successful test case is one that detects an as-yet undiscovered error."[14]: 16 ), it illustrated the desire of the software engineering community to separate fundamental development activities, such as debugging, from that of verification.

Software faults occur through the following process: A programmer makes an error (mistake), which results in a fault (defect, bug) in the software source code. If this fault is executed, in certain situations the system will produce wrong results, causing a failure.

Testing cannot establish that a product functions properly under all conditions, but only that it does not function properly under specific conditions.

A healing resolution for the issue generally is supposedly achieved after repositioning the representatives and adding key members of the system who have been forgotten or written out of the family history. When every representative feels right in his or her place and the other representatives agree, the facilitator may suggest one or two sentences to be spoken aloud. If the representatives do not feel at peace with their new position or sentences, they can move again or try a different sentence. This is claimed, in an abstract way, to represent a possible resolution of the issues faced by the seeker. Sometimes the process concludes without a full resolution being achieved.

Schwa[edit] When phonetically realised, schwa (/ə/), also called e caduc ('dropped e') and e muet ('mute e'), is a mid-central vowel with some rounding.[22] Many authors consider its value to be [œ],[37][38] while Geoff Lindsey suggests [ɵ].[39][40] Fagyal, Kibbee & Jenkins (2006) state, more specifically, that it merges with /ø/ before high vowels and glides: netteté /nɛtəte/ → [nɛ.tø.te] ('clarity'), atelier /atəlje/ → [a.tø.lje] ('workshop'), in phrase-final stressed position: dis-le ! /di lə/ → [di.ˈlø] ('say it'), and that it merges with /œ/ elsewhere.[41] However, some speakers make a clear distinction, and it exhibits special phonological behavior that warrants considering it a distinct phoneme. Furthermore, the merger occurs mainly in the French of France; in Quebec, /ø/ and /ə/ are still distinguished.[42] The main characteristic of French schwa is its "instability": the fact that under certain conditions it has no phonetic realization. That is usually the case when it follows a single consonant in a medial syllable: appeler /apəle/ → [ap.le] ('to call'), It is occasionally mute in word-final position: porte /pɔʁtə/ → [pɔʁt] ('door'). Word-final schwas are optionally pronounced if preceded by two or more consonants and followed by a consonant-initial word: une porte fermée /yn(ə) pɔʁt(ə) fɛʁme/ → [yn.pɔʁ.t(ə).fɛʁ.me] ('a closed door'). In the future and conditional forms of -er verbs, however, the schwa is sometimes deleted even after two consonants[citation needed]: tu garderais /ty ɡaʁdəʁɛ/ → [ty.ɡaʁ.d(ə.)ʁɛ] ('you would guard'), nous brusquerons [les choses] /nu bʁyskəʁɔ̃/ → [nu.bʁys.k(ə.)ʁɔ̃] ('we will precipitate [things]'). On the other hand, it is pronounced word-internally when it follows more pronounced consonants that cannot be combined into a complex onset with the initial consonants of the next syllable: gredin /ɡʁədɛ̃/ → [ɡʁə.dɛ̃] ('scoundrel'), sept petits /sɛt pəti/ → [sɛt.pə.ti] ('seven little ones').[43] In French versification, word-final schwa is always elided before another vowel and at the ends of verses. It is pronounced before a following consonant-initial word.[44] For example, une grande femme fut ici, [yn ɡʁɑ̃d fam fy.t‿i.si] in ordinary speech, would in verse be pronounced [y.nə ɡʁɑ̃.də fa.mə fy.t‿i.si], with the /ə/ enunciated at the end of each word. Schwa cannot normally be realised as a front vowel ([œ]) in closed syllables. In such contexts in inflectional and derivational morphology, schwa usually alternates with the front vowel /ɛ/: harceler /aʁsəle/ → [aʁ.sœ.le] ('to harass'), with il harcèle /il aʁsɛl/ → [i.laʁ.sɛl] ('[he] harasses').[45] A three-way alternation can be observed, in a few cases, for a number of speakers: appeler /apəle/ → [ap.le] ('to call'), j'appelle /ʒ‿apɛl/ → [ʒa.pɛl] ('I call'), appellation /apelasjɔ̃/ → [a.pe.la.sjɔ̃] ('brand'), which can also be pronounced [a.pɛ.la.sjɔ̃].[46] Instances of orthographic ⟨e⟩ that do not exhibit the behaviour described above may be better analysed as corresponding to the stable, full vowel /œ/. The enclitic pronoun le, for example, always keeps its vowel in contexts like donnez-le-moi /dɔne lə mwa/ → [dɔ.ne.lœ.mwa] ('give it to me') for which schwa deletion would normally apply (giving *[dɔ.nɛl.mwa]), and it counts as a full syllable for the determination of stress. Cases of word-internal stable ⟨e⟩ are more subject to variation among speakers, but, for example, un rebelle /œ̃ ʁəbɛl/ ('a rebel') must be pronounced with a full vowel in contrast to un rebond /œ̃ ʁəbɔ̃/ → or [œ̃ʁ.bɔ̃] ('a bounce').[47]

A variable is considered dependent if it depends on an independent variable. Dependent variables are studied under the supposition or demand that they depend, by some law or rule (e.g., by a mathematical function), on the values of other variables. Independent variables, in turn, are not seen as depending on any other variable in the scope of the experiment in question.[a]

Just as science has historically excluded communities of Black, Indigenous and people of color,[80] LGBTQ+ communities[81] and communities of lower socioeconomic status or education,[80] science communication has also failed to center these audiences.[82][83] Science communication cannot be inclusive or effective if these communities are not involved in both the creation and dissemination of science information.[84][85] One strategy to improve inclusivity in science communication is by building philanthropic coalitions with marginalized communities.[85][86][87]
