Indian Rupee
The Indian rupee (symbol: ₹; code: INR) is the official currency of India. The rupee is subdivided into 100 '' paise'' (Hindi plural; singular: ''paisa''). The issuance of the currency is controlled by the Reserve Bank of India. The Reserve Bank derives this role from powers vested to it by the Reserve Bank of India Act, 1934. Etymology Pāṇini (6th to 4th century BCE), the ancient Indian grammarian and logician, writes of the (). While it is unclear whether Panini was referring specifically to coinage, some scholars conclude that he uses the term ''rūpa'' to mean a piece of precious metal (typically silver) used as a coin, and a ''rūpya'' to mean a stamped piece of metal, a coin in the modern sense. The ''Arthashastra'', written by Chanakya, prime minister to the first Maurya emperor Chandragupta Maurya (), mentions silver coins as . Other types of coins, including gold coins (), copper coins (), and lead coins (), are also mentioned. The immediate precursor to t ...

Ferritic Stainless Steel
Ferritic stainless steels are a family of stainless steels with a body-centered cubic (BCC) crystal structure and composed primarily of iron and chromium. They are characterized by being magnetic, non-hardenable by heat treating, and having excellent resistance to stress-corrosion cracking (SCC). Ferritic stainless steel alloys are designated as part of the 400-series of stainless steels in the SAE steel grades numbering system. By comparison with austenitic stainless steels, these are less hardenable by cold working and less weldable, but more cost-effective due to the lower nickel content. History Canadian-born engineer Frederick Mark Becket (1875-1942) at Union Carbide industrialised ferritic stainless steel around 1912, on the basis of "using silicon instead of carbon as a reducing agent in metal production, thus making low-carbon ferroalloys and certain steels practical". He discovered a ferrous alloy with 25-27% Chromium that "was the first of the high-chromium alloys t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lion Capital Of Ashoka
The Lion Capital of Ashoka is the capital, or head, of a column erected by the Mauryan emperor Ashoka in Sarnath, India, . Its crowning features are four life-sized lions set back to back on a drum-shaped abacus. The side of the abacus is adorned with wheels in relief, and interspersing them, four animals, a lion, an elephant, a bull, and a galloping horse follow each other from right to left. A bell-shaped lotus forms the lowest member of the capital, and the whole tall, carved out of a single block of sandstone and highly polished, was secured to its monolithic column by a metal dowel. Erected after Ashoka's conversion to Buddhism, it commemorated the site of Gautama Buddha's first sermon some two centuries before. The capital eventually fell to the ground and was buried. It was excavated by the Archeological Survey of India (ASI) in the very early years of the 20th century. The excavation was undertaken by F. O. Oertel in the ASI winter season of 1904–1905. Th ...

India
India, officially the Republic of India, is a country in South Asia. It is the List of countries and dependencies by area, seventh-largest country by area; the List of countries by population (United Nations), most populous country since 2023; and, since its independence in 1947, the world's most populous democracy. Bounded by the Indian Ocean on the south, the Arabian Sea on the southwest, and the Bay of Bengal on the southeast, it shares land borders with Pakistan to the west; China, Nepal, and Bhutan to the north; and Bangladesh and Myanmar to the east. In the Indian Ocean, India is near Sri Lanka and the Maldives; its Andaman and Nicobar Islands share a maritime border with Thailand, Myanmar, and Indonesia.

Cupronickel
Cupronickel or copper–nickel (CuNi) is an alloy of copper with nickel, usually along with small quantities of other metals added for strength, 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 industry, petrochemical industry, and electrical industries. In decorative use, a cupronickel alloy called nickel silver is common, although it contains additional zinc but no silver. Another common 20th-century use of cupronickel was silver-coloured coins. For this use, the typical alloy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stainless Steel
Stainless steel, also known as inox, corrosion-resistant steel (CRES), or rustless steel, is an iron-based alloy that contains chromium, making it resistant to rust and corrosion. Stainless steel's resistance to corrosion comes from its chromium content of 11% or more, which forms a Passivation (chemistry), passive film that protects the material and can self-healing material, self-heal when exposed to oxygen. It can be further alloyed with elements like molybdenum, carbon, nickel and nitrogen to enhance specific properties for various applications. The alloy's properties, such as luster and resistance to corrosion, are useful in many applications. Stainless steel can be rolled into Sheet metal, sheets, plates, bars, wire, and tubing. These can be used in cookware, cutlery, surgical instruments, major appliances, vehicles, construction material in large buildings, industrial equipment (e.g., in paper mills, chemical plants, water treatment), and storage tanks and tankers for ch ...

Hendecagon
In geometry, a hendecagon (also undecagon or endecagon) or 11-gon is an eleven-sided polygon. (The name ''hendecagon'', from Greek ''hendeka'' "eleven" and ''–gon'' "corner", is often preferred to the hybrid ''undecagon'', whose first part is formed from Latin ''undecim'' "eleven".) Regular hendecagon A '' regular hendecagon'' is represented by Schläfli symbol . A regular hendecagon has internal angles of 147. degrees (=147 \tfrac degrees). The area of a regular hendecagon with side length ''a'' is given by. :A = \fraca^2 \cot \frac \simeq 9.36564\,a^2. As 11 is not a Fermat prime, the regular hendecagon is not constructible with compass and straightedge. Because 11 is not a Pierpont prime, construction of a regular hendecagon is still impossible even with the usage of an angle trisector. Close approximations to the regular hendecagon can be constructed. For instance, the ancient Greek mathematicians approximated the side length of a hendecagon inscribed in a unit circl ...

Coins Of India
The Coinage of India began anywhere between early 1st millennium BCE to the 6th century BCE, and consisted mainly of copper and silver coins in its initial stage.Allan & Stern (2008) The coins of this period were ''Karshapanas'' or ''Pana''. A variety of earliest Indian coins, however, unlike those circulated in West Asia, were stamped bars of metal, suggesting that the innovation of stamped currency was added to a pre-existing form of token currency which had already been present in the Janapadas and Mahajanapada kingdoms of the Early historic India. The kingdoms that minted their own coins included Gandhara, Kuntala, Kuru, Magadha, Panchala, Shakya, Surasena, Surashtra and Vidarbha etc. The tradition of Indian coinage in the 2nd millennium evolved with Indo Islamic rule in India.Allan & Stern (2008) and the British Raj in the 19th century.Sutherland (2008) Origin of currency in Indian subcontinent Prehistoric and Bronze Age origins Cowry shells were first used i ...

Currencies Introduced In 1982
A currency is a standardization of money in any form, in use or currency in circulation, circulation as a medium of exchange, for example banknotes and coins. A more general definition is that a currency is a ''system of money'' in common use within a specific environment over time, especially for people in a nation state. Under this definition, the Pound sterling, British Pound sterling (£), euros (€), Japanese yen (¥), and United States dollar, U.S. dollars (US$) are examples of (government-issued) fiat currencies. Currencies may act as store of value, stores of value and be traded between nations in foreign exchange markets, which determine the relative values of the different currencies. Currencies in this sense are either chosen by users or decreed by governments, and each type has limited boundaries of acceptance; i.e., legal tender laws may require a particular unit of account for Payment, payments to government agencies.
