A primate city is a major city that works as the financial, political, and population center of a country and is not rivaled in any of these aspects by any other city in that country.
 Normally, a primate city must be at least twice as populous as the second largest city in the country.
 The presence of a primate city in a country usually indicates an imbalance in development — usually a progressive core, and a lagging periphery, on which the primate city depends for labor and other resources.
 Not all countries have primate cities (United States, Germany, India, and the People's Republic of China, for example), but in those that do, the rest of the country depends on it for cultural, economic, political, and major transportation needs.
 Among the best known examples of primate cities are the alpha world cities of London and Paris.
 Other major primate cities include Athens, Baghdad, Bangkok, Budapest, Buenos Aires, Cairo, Dublin, Jakarta, Kuala Lumpur, Lima, Mexico City, Moscow, Seoul, Tehran,Tokyo and Vienna.
 Bangkok has been called "the most primate city on earth", being forty times larger than Thailand's second city.
Islam in Liberia is practiced by an estimated 12.2% of the population.
 The vast majority of Liberian Muslims are Malikite Sunni, with sizeable Shia and Ahmadiyya minorities.
 The primary Muslim ethnic groups are the Vai and Mandingo but also Gbandi, Kpelle and other ethnic groups.
 Historically, Liberian Muslims have followed a relaxed and liberal form of Islam that is heavily influenced by indigenous religions that were integrated into Islam when it came to Liberia in the 16th century with the collapse of the Songhai Empire in Mali.
 Islamic religious practices vary in cities and towns across the country.
 Younger Liberian Muslims, particularly in the cities along the coast, tend to be more secular but still practice Islam in everyday life.
 In rural areas, Liberian Muslims are more conservative in dressing modestly, performing prayers and attending religious studies.
 The practice of Islam in Liberia has been compared to Sufi Islam common in Senegal and Gambia.
 The major Islamic holidays, Eid el Fitr, Ramadan and Eid al Adha, called Tabaski Day, are celebrated annually in Liberia.
 People have begun to go on Hajj to Mecca in recent years.
 Joint English-Arabic language, Quranic, and Muslim universities and Islamic studies schools have opened and been rebuilt in the capital Monrovia, rural towns and other cities.
 Islam appears to be experiencing revival alongside Christianity in the country as a result of the Liberian Civil War.
 America-Liberian Methodists, the first Christians in Liberia, arrived on January 7, 1822.
Arab immigration to the United States began when Arab accompanied Spanish explorers to the US in the 15th century.
 During the Revolutionary War, horses exported from Algeria replenished the American cavalry and Morocco was the first country to officially recognize the independence of the United States in 1787 in what is known as the "treaty of Friendship".
 However, Arabs did not start immigrating to the United States in significant numbers until the 19th century.
 Since the first major wave of Arab immigration in the late 19th century, the majority of Arab immigrants have settled in or near large cities.
 Roughly 94 percent of all Arab immigrants live in metropolitan areas, and nearly one third of all Arab Americans live in or around just three cities: New York, Los Angeles and Detroit.
 While most Arab-Americans have similarly settled in just a handful of major American cities, they form a fairly diverse population representing nearly every country and religion from the Arab world.
The Sanmenxia Dam is a concrete gravity dam on the middle-reaches of the Yellow River near Sanmenxia Gorge on the border between Shanxi province and Henan Province, China.
 The dam is multi-purpose and was constructed for flood and ice control along with irrigation, hydroelectric power generation and navigation.
 Construction began in 1957 and was completed in 1960.
 It is the first major water control project on the Yellow River and was viewed as a major achievement of the new People's Republic of China.
 Subsequently, its image was printed on the country's bank notes.
 However, due to sediment accumulation in the reservoir, the dam later had to be re-engineered and renovated.
 The effects from sediment, which include flooding upstream, have placed the dam at the center of controversy and criticism-related arrests by the Chinese government.
