Jordanian Dinar
The Jordanian dinar ( ar, دينار أردني; ISO 4217, code: JOD; unofficially abbreviated as JD) has been the currency of Jordan since 1950. The dinar is divided into 10 dirhams, 100 qirsh (also called piastres) or 1000 fils (currency), fulus. It is pegged to the US dollar. The Central Bank of Jordan commenced operations in 1964 and became the sole issuer of Jordanian currency, in place of the Jordan Currency Board. The Jordanian dinar is also widely used in the West Bank alongside the Israeli new shekel, Israeli shekel. History In 1927, the British administration of the Palestinian Mandate established the Palestine Currency Board which issued the Palestine pound which was the official currency in both Mandatory Palestine and the Emirate of Transjordan. Though Jordan became an independent kingdom on 25 May 1946, it continued to use the Palestinian pound for a while. In 1949, it passed the Provisional Act No. 35 of 1949, which established the Jordan Currency Board as the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
US Dollar
The United States dollar (symbol: $; code: USD; also abbreviated US$ or U.S. Dollar, to distinguish it from other dollar-denominated currencies; referred to as the dollar, U.S. dollar, American dollar, or colloquially buck) is the official currency of the United States and several other countries. The Coinage Act of 1792 introduced the U.S. dollar at par with the Spanish silver dollar, divided it into 100 cents, and authorized the minting of coins denominated in dollars and cents. U.S. banknotes are issued in the form of Federal Reserve Notes, popularly called greenbacks due to their predominantly green color. The monetary policy of the United States is conducted by the Federal Reserve System, which acts as the nation's central bank. The U.S. dollar was originally defined under a bimetallic standard of (0.7735 troy ounces) fine silver or, from 1837, fine gold, or $20.67 per troy ounce. The Gold Standard Act of 1900 linked the dollar solely to gold. From 1934, its equi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arabic Language
Arabic (, ' ; , ' or ) is a Semitic language spoken primarily across the Arab world.Semitic languages: an international handbook / edited by Stefan Weninger; in collaboration with Geoffrey Khan, Michael P. Streck, Janet C. E.Watson; Walter de Gruyter GmbH & Co. KG, Berlin/Boston, 2011. Having emerged in the 1st century, it is named after the Arab people; the term "Arab" was initially used to describe those living in the Arabian Peninsula, as perceived by geographers from ancient Greece. Since the 7th century, Arabic has been characterized by diglossia, with an opposition between a standard prestige language—i.e., Literary Arabic: Modern Standard Arabic (MSA) or Classical Arabic—and diverse vernacular varieties, which serve as mother tongues. Colloquial dialects vary significantly from MSA, impeding mutual intelligibility. MSA is only acquired through formal education and is not spoken natively. It is the language of literature, official documents, and formal written m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hussein Bin Ali, Sharif Of Mecca
Hussein bin Ali al-Hashimi ( ar, الحسين بن علي الهاشمي, al-Ḥusayn bin ‘Alī al-Hāshimī; 1 May 18544 June 1931) was an Arab leader from the Banu Hashim clan who was the Sharif and Emir of Mecca from 1908 and, after proclaiming the Great Arab Revolt against the Ottoman Empire, King of the Hejaz from 1916 to 1924 and Caliphate, Caliph from 1924 to 1925. After the Abolition of the Caliphate, abolition of the Ottoman Caliphate he was briefly proclaimed Sharifian Caliph, Caliph until the invasion of the Hejaz by the Saudis the following year. He was a Hashemites#Ancestry, 37th-generation direct descendant of Muhammad, as he belonged to the Hashemite family. A member of the Dhawu Awn clan of the Qatadid emirs of Mecca, he was perceived to have rebellious inclinations and in 1893 was summoned to Istanbul, where he was kept on the Council of State. In 1908, in the aftermath of the Young Turk Revolution, he was appointed Emir of Mecca by the List of sultans of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1 JOD Reverse1
1 (one, unit, unity) is a number representing a single or the only entity. 1 is also a numerical digit and represents a single unit of counting or measurement. For example, a line segment of ''unit length'' is a line segment of length 1. In conventions of sign where zero is considered neither positive nor negative, 1 is the first and smallest positive integer. It is also sometimes considered the first of the infinite sequence of natural numbers, followed by 2, although by other definitions 1 is the second natural number, following 0. The fundamental mathematical property of 1 is to be a multiplicative identity, meaning that any number multiplied by 1 equals the same number. Most if not all properties of 1 can be deduced from this. In advanced mathematics, a multiplicative identity is often denoted 1, even if it is not a number. 1 is by convention not considered a prime number; this was not universally accepted until the mid-20th century. Additionally, 1 is the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cupronickel
Cupronickel or copper-nickel (CuNi) is an alloy of copper that contains nickel and strengthening elements, such as iron and manganese. The copper content typically varies from 60 to 90 percent. (Monel is a nickel-copper alloy that contains a minimum of 52 percent nickel.) Despite its high copper content, cupronickel is silver in colour. Cupronickel is highly resistant to corrosion by salt water, and is therefore used for piping, heat exchangers and condensers in seawater systems, as well as for marine hardware. It is sometimes used for the propellers, propeller shafts, and hulls of high-quality boats. Other uses include military equipment and chemical, petrochemical, and electrical industries. Another common 20th-century use of cupronickel was silver-coloured coins. For this use, the typical alloy has 3:1 copper to nickel ratio, with very small amounts of manganese. In the past, true silver coins were debased with cupronickel, such as coins of the pound sterling from 1947 onwar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aluminium Bronze
Aluminium bronze is a type of bronze in which aluminium is the main alloying metal added to copper, in contrast to standard bronze (copper and tin) or brass (copper and zinc). A variety of aluminium bronzes of differing compositions have found industrial use, with most ranging from 5% to 11% aluminium by weight, the remaining mass being copper; other alloying agents such as iron, nickel, manganese, and silicon are also sometimes added to aluminium bronzes. Compositions The following table lists the most common standard aluminium bronze wrought alloy compositions, by ISO 428 designations. The percentages show the proportional composition of the alloy by weight. Copper is the remainder by weight and is not listed: Material properties Aluminium bronzes are most valued for their higher strength and corrosion resistance as compared to other bronze alloys. These alloys are tarnish-resistant and show low rates of corrosion in atmospheric conditions, low oxidation rates at high temp ...

Brass
Brass is an alloy of copper (Cu) and zinc (Zn), in proportions which can be varied to achieve different mechanical, electrical, and chemical properties. It is a substitutional alloy: atoms of the two constituents may replace each other within the same crystal structure. Brass is similar to bronze, another copper alloy, that uses tin instead of zinc. Both bronze and brass may include small proportions of a range of other elements including arsenic (As), lead (Pb), phosphorus (P), aluminium (Al), manganese (Mn), and silicon (Si). Historically, the distinction between the two alloys has been less consistent and clear, and modern practice in museums and archaeology increasingly avoids both terms for historical objects in favor of the more general "copper alloy". Brass has long been a popular material for decoration due to its bright, gold-like appearance; being used for drawer pulls and doorknobs. It has also been widely used to make utensils because of its low melting ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heptagon
In geometry, a heptagon or septagon is a seven-sided polygon or 7-gon. The heptagon is sometimes referred to as the septagon, using "sept-" (an elision of ''septua-'', a Latin-derived numerical prefix, rather than ''hepta-'', a Greek-derived numerical prefix; both are cognate) together with the Greek suffix "-agon" meaning angle. Regular heptagon A regular heptagon, in which all sides and all angles are equal, has internal angles of 5π/7 radians (128 degrees). Its Schläfli symbol is . Area The area (''A'') of a regular heptagon of side length ''a'' is given by: :A = \fraca^2 \cot \frac \simeq 3.634 a^2. This can be seen by subdividing the unit-sided heptagon into seven triangular "pie slices" with vertices at the center and at the heptagon's vertices, and then halving each triangle using the apothem as the common side. The apothem is half the cotangent of \pi/7, and the area of each of the 14 small triangles is one-fourth of the apothem. The area of a regular heptago ...

Nickel
Nickel is a chemical element with symbol Ni and atomic number 28. It is a silvery-white lustrous metal with a slight golden tinge. Nickel is a hard and ductile transition metal. Pure nickel is chemically reactive but large pieces are slow to react with air under standard conditions because a passivation layer of nickel oxide forms on the surface that prevents further corrosion. Even so, pure native nickel is found in Earth's crust only in tiny amounts, usually in ultramafic rocks, and in the interiors of larger nickel–iron meteorites that were not exposed to oxygen when outside Earth's atmosphere. Meteoric nickel is found in combination with iron, a reflection of the origin of those elements as major end products of supernova nucleosynthesis. An iron–nickel mixture is thought to compose Earth's outer and inner cores. Use of nickel (as natural meteoric nickel–iron alloy) has been traced as far back as 3500 BCE. Nickel was first isolated and classified as an e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eastern Arabic Numerals
The Eastern Arabic numerals, also called Arabic-Hindu numerals or Indo–Arabic numerals, are the symbols used to represent numerical digits in conjunction with the Arabic alphabet in the countries of the Mashriq (the east of the Arab world), the Arabian Peninsula, and its variant in other countries that use the Persian numerals on the Iranian plateau and in Asia. Origin The numeral system originates from an ancient Indian numeral system, which was re-introduced in the book ''On the Calculation with Hindu Numerals'' written by the Islamic Golden Age mathematician and engineer al-Khwarizmi, whose name was Latinized as ''Algoritmi''.Other Latin transliterations include ''Algaurizin''. Other names These numbers are known as () in Arabic. They are sometimes also called ''Indic numerals'' in English. However, that is sometimes discouraged as it can lead to confusion with Indian numerals, used in Brahmic scripts of the Indian subcontinent. Numerals Each numeral in the Pe ...

Abdullah II Of Jordan
Abdullah II bin Al-Hussein ( ar, عبدالله الثاني بن الحسين , translit=ʿAbd Allāh aṯ-ṯānī ibn al-Ḥusayn; born 30 January 1962) is King of Jordan, having ascended the throne on 7 February 1999. He is a member of the Hashemite dynasty, who have been the reigning royal family of Jordan since 1921, and is considered a 41st-generation direct descendant of the Islamic prophet Muhammad. Abdullah was born in Amman as the first child of King Hussein and his second wife, Princess Muna. As the king's eldest son, Abdullah was heir apparent until Hussein transferred the title to Abdullah's uncle, Prince Hassan, in 1965. Abdullah began his schooling in Amman, continuing his education abroad. He began his military career in 1980 as a training officer in the Jordanian Armed Forces, later assuming command of the country's Special Forces in 1994, eventually becoming a major general in 1998.
