This created a problem for Alexander as to whether he had to make use of the various segments and people that had given the empire its solidity and unity for a lengthy period of time. Pierre Briant explains that Alexander realized that it was insufficient to merely exploit the internal contradictions within the imperial system as in Asia Minor, Babylonia or Egypt; he also had to (re)create a central government with or without the support of the Iranians. As early as 334 BC he demonstrated awareness of this, when he challenged incumbent King Darius III \"by appropriating the main elements of the Achaemenid monarchy's ideology, particularly the theme of the king who protects the lands and the peasants\". Alexander wrote a letter in 332 BC to Darius III, wherein he argued that he was worthier than Darius \"to succeed to the Achaemenid throne\". However, Alexander's eventual decision to burn the Achaemenid palace at Persepolis in conjunction with the major rejection and opposition of the \"entire Persian people\" made it impracticable for him to pose himself as Darius' legitimate successor.

He placed Asparagus within the Hexandria Monogynia (six stamens, one carpel) in his sexual classification in the Species Plantarum. The majority of taxa now considered to constitute Asparagales have historically been placed within the very large and diverse family, Liliaceae. The family Liliaceae was first described by Michel Adanson in 1763, and in his taxonomic scheme he created eight sections within it, including the Asparagi with Asparagus and three other genera. The system of organising genera into families is generally credited to Antoine Laurent de Jussieu who formally described both the Liliaceae and the type family of Asparagales, the Asparagaceae, as Lilia and Asparagi, respectively, in 1789. Jussieu established the hierarchical system of taxonomy (phylogeny), placing Asparagus and related genera within a division of Monocotyledons, a class (III) of Stamina Perigynia and 'order' Asparagi, divided into three subfamilies. The use of the term Ordo (order) at that time was closer to what we now understand as Family, rather than Order. In creating his scheme he used a modified form of Linnaeus' sexual classification but using the respective topography of stamens to carpels rather than just their numbers. While De Jussieu's Stamina Perigynia also included a number of 'orders' that would eventually form families within the Asparagales such as the Asphodeli (Asphodelaceae), Narcissi (Amaryllidaceae) and Irides (Iridaceae), the remainder are now allocated to other orders. Jussieu's Asparagi soon came to be referred to as Asparagacées in the French literature (Latin: Asparagaceae).

Safaitic and Hismaic, previously considered ANA, should be considered Old Arabic due to the fact that they participate in the innovations common to all forms of Arabic.The earliest attestation of continuous Arabic text in an ancestor of the modern Arabic script are three lines of poetry by a man named Garm(')allāhe found in En Avdat, Israel, and dated to around 125 CE. This is followed by the Namara inscription, an epitaph of the Lakhmid king Imru' al-Qays bar 'Amro, dating to 328 CE, found at Namaraa, Syria. From the 4th to the 6th centuries, the Nabataean script evolves into the Arabic script recognizable from the early Islamic era. There are inscriptions in an undotted, 17-letter Arabic script dating to the 6th century CE, found at four locations in Syria (Zabad, Jabal 'Usays, Harran, Umm al-Jimaal). The oldest surviving papyrus in Arabic dates to 643 CE, and it uses dots to produce the modern 28-letter Arabic alphabet.

There was also the idea of finding a way to use Hieroglyphics instead of the Latin alphabet, but this was seen as too complicated to use. A scholar, Salama Musa agreed with the idea of applying a Latin alphabet to Arabic, as he believed that would allow Egypt to have a closer relationship with the West.

This change in alphabet, he believed, would solve the problems inherent with Arabic, such as a lack of written vowels and difficulties writing foreign words that made it difficult for non-native speakers to learn.

These systems are heavily reliant on diacritical marks such as \"š\" for the sound equivalently written sh in English. Other systems (e.g. the Bahá'í orthography) are intended to help readers who are neither Arabic speakers nor linguists with intuitive pronunciation of Arabic names and phrases. These less \"scientific\" systems tend to avoid diacritics and use digraphs (like sh and kh). These are usually simpler to read, but sacrifice the definiteness of the scientific systems, and may lead to ambiguities, e.g. whether to interpret sh as a single sound, as in gash, or a combination of two sounds, as in gashouse.

This made the water flow of the Amstel more active, so excess water could be drained better. With drier banks, the downstream Amstel mouth became attractive for permanent habitation. Moreover, the river had grown from an insignificant peat stream into a junction of international waterways. A settlement was built here immediately after the landscape change of 1170, and right from the start of its foundation it focused on traffic, production and trade; not on farming, as opposed to how communities had lived further upstream for the past 200 years and northward for thousands of years. The construction of a dam at the mouth of the Amstel, eponymously named Dam, is historically estimated to have occurred between 1264 and 1275.

Other immigrants, including refugees asylum seekers and illegal immigrants, came from Europe, America, Asia and Africa. In the 1970s and 1980s, many 'old' Amsterdammers moved to 'new' cities like Almere and Purmerend, prompted by the third planological bill of the Dutch Government. This bill promoted suburbanisation and arranged for new developments in so-called \"groeikernen\", literally cores of growth. Young professionals and artists moved into neighborhoods De Pijp and the Jordaan abandoned by these Amsterdammers. The non-Western immigrants settled mostly in the social housing projects in Amsterdam-West and the Bijlmer. Today, people of non-Western origin make up approximately one-fifth of the population of Amsterdam, and more than 30% of the city's children. Ethnic Dutch (as defined by the Dutch census) now make up a minority of the total population, although by far the largest one. Only one in three inhabitants under 15 is an autochthon, or a person who has two parents of Dutch origin. Segregation along ethnic lines is clearly visible, with people of non-Western origin, considered a separate group by Statistics Netherlands, concentrating in specific neighbourhoods especially in Nieuw-West, Zeeburg, Bijlmer and in certain areas of Amsterdam-Noord.", "section_idx": 3, "section_name": "Demographics", "target_page_ids": [ 23476997, 384142, 1631031, 1621432, 7124412, 29833, 118444, 120174, 603913, 27829489, 2266832, 177912, 1656551, 409682, 27829444, 5431958, 1631031, 8167908 ], "anchor_spans": [ [ 129, 146 ], [ 184, 197 ], [ 368, 375 ], [ 419, 433 ], [ 438, 456 ], [ 476, 483 ], [ 578, 584 ], [ 589, 598 ], [ 622, 634 ], [ 846, 853 ], [ 862, 869 ], [ 953, 967 ], [ 1171, 1178 ], [ 1504, 1526 ], [ 1583, 1593 ], [ 1595, 1602 ], [ 1604, 1611 ], [ 1636, 1651 ] ] }, { "plaintext": "In 2000, Christians formed the largest religious group in the city (28% of the population).

On iOS, a date bug caused iOS devices that received local app notifications at 12:15am on December 2, 2017, to repeatedly restart. Users were recommended to turn off notifications for their apps. Apple quickly released an update, done during the nighttime in Cupertino, California time and outside of their usual software release window, with one of the headlining features of the update needing to be delayed for a few days.

Western successes led to General Ulysses S. Grant's command of all Union armies in 1864. Inflicting an ever-tightening naval blockade of Confederate ports, the Union marshaled resources and manpower to attack the Confederacy from all directions. This led to the fall of Atlanta in 1864 to Union General William Tecumseh Sherman, followed by his march to the sea. The last significant battles raged around the ten-month Siege of Petersburg, gateway to the Confederate capital of Richmond. The Confederates abandoned Richmond, and on April 9, 1865, Lee surrendered to Grant following the Battle of Appomattox Court House, setting in motion the end of the war.

It did not immediately dawn on his political rivals that his calls for rationalization and reorganization were hiding his desire to sideline them and take control.

Naval armaments were not under Speer's supervision until October 1943, nor the Luftwaffe's armaments until June of the following year.
