North Vietnamese đồng
The đồng (Chữ Nôm: 銅; Chữ Hán: 元, ''nguyên'') (; ) was the currency of North Vietnam from 3 November 1946 to 2 May 1978. It was subdivided into 10 ''hào'', each itself divided into 10 ''xu''. History The first đồng issued by the communists controlling northern Vietnam was introduced on January 31, 1946, and replaced the French Indochinese piastre at par. Two revaluations followed. In 1951, the second đồng was introduced at a rate of 1 1951 đồng = 100 1946 đồng. However, some sources say there were two consecutive revaluations in 1951 and 1953, each with factor of 10. In 1954, this became the currency of the newly recognized state of North Vietnam, with an exchange rate to the still circulating piastre and South Vietnamese đồng of 32 northern đồng = 1 piastre or southern đồng. In 1956, the đồng was pegged to the Chinese renminbi yuan at a rate of 1.47 đồng = 1 yuan. On 28 February 1959, another đồng replaced the second at a rate of ...

State Bank Of Vietnam
The State Bank of Vietnam ( vi, Ngân hàng Nhà nước Việt Nam) is the central bank of Vietnam. It currently holds an about 65% stake of VietinBank - the country's largest listed bank by capital. History When Indochina was under French rule, the colonial government governed the Indochinese monetary system through Banque de l'Indochine, which also acted as a commercial bank in French Indochina. After the August Revolution in 1945, the government of the Democratic Republic of Vietnam gradually attempted to exercise a monetary system independent from France. On 6 May 1951, president Hồ Chí Minh signed decree 15/SL on establishment of National Bank of Vietnam (''Ngân hàng Quốc gia Việt Nam''). On 21 January 1960, the governor of the bank signed an ordinance on behalf of the prime minister to rename the bank State Bank of Vietnam (''Ngân hàng Nhà nước Việt Nam''). After the fall of Saigon, the two Vietnams were united but not until July 1976 did the two cou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
5 Hào - North Vietnam (1946) 02
5 (five) is a number, numeral and digit. It is the natural number, and cardinal number, following 4 and preceding 6, and is a prime number. It has attained significance throughout history in part because typical humans have five digits on each hand. In mathematics 5 is the third smallest prime number, and the second super-prime. It is the first safe prime, the first good prime, the first balanced prime, and the first of three known Wilson primes. Five is the second Fermat prime and the third Mersenne prime exponent, as well as the third Catalan number, and the third Sophie Germain prime. Notably, 5 is equal to the sum of the ''only'' consecutive primes, 2 + 3, and is the only number that is part of more than one pair of twin primes, ( 3, 5) and (5, 7). It is also a sexy prime with the fifth prime number and first prime repunit, 11. Five is the third factorial prime, an alternating factorial, and an Eisenstein prime with no imaginary part and real part of the for ...

Aluminium
Aluminium (aluminum in American and Canadian English) is a chemical element with the symbol Al and atomic number 13. Aluminium has a density lower than those of other common metals, at approximately one third that of steel. It has a great affinity towards oxygen, and forms a protective layer of oxide on the surface when exposed to air. Aluminium visually resembles silver, both in its color and in its great ability to reflect light. It is soft, non-magnetic and ductile. It has one stable isotope, 27Al; this isotope is very common, making aluminium the twelfth most common element in the Universe. The radioactivity of 26Al is used in radiodating. Chemically, aluminium is a post-transition metal in the boron group; as is common for the group, aluminium forms compounds primarily in the +3 oxidation state. The aluminium cation Al3+ is small and highly charged; as such, it is polarizing, and bonds aluminium forms tend towards covalency. The strong affinity tow ...

1 Xu - North-Vietnam (1958) Art-Hanoi 02
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 th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
