Indian Rupee
The Indian rupee ( symbol: ₹; code: INR) is the official currency in the republic of India. The rupee is subdivided into 100 ''paise'' (singular: ''paisa''), though as of 2022, coins of denomination of 1 rupee are the lowest value in use whereas 2000 rupees is the highest. The issuance of the currency is controlled by the Reserve Bank of India. The Reserve Bank manages currency in India and derives its role in currency management on the basis of the Reserve Bank of India Act, 1934. Etymology The immediate precursor of the rupee is the ''rūpiya''—the silver coin weighing 178 grains minted in northern India by first Sher Shah Suri during his brief rule between 1540 and 1545 and adopted and standardized later by the Mughal Empire. The weight remained unchanged well beyond the end of the Mughals until the 20th century. Though Pāṇini mentions (), it is unclear whether he was referring to coinage.

Ferritic Stainless Steel
Ferritic stainless steel forms one of the five stainless steel families, the other four being austenitic, martensitic, duplex stainless steels, and ''precipitation hardened''. For example, many of AISI 400-series of stainless steels are ferritic steels. By comparison with austenitic types, these are less hardenable by cold working, less weldable, and should not be used at cryogenic temperatures. Some types, like the 430, have excellent corrosion resistance and are very heat tolerant. 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 that became known as heat-resisting stainless steel." Ferritic stainless steels were discovered early but it was on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lion Capital Of Ashoka
The Lion Capital of Ashoka is the Capital (architecture), 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 (architecture), 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 Dhammacakkappavattana Sutta, 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 wa ...

India
India, officially the Republic of India (Hindi: ), is a country in South Asia. It is the seventh-largest country by area, the second-most populous country, and the most populous democracy in the world. 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 in the vicinity of Sri Lanka and the Maldives; its Andaman and Nicobar Islands share a maritime border with Thailand, Myanmar, and Indonesia. Modern humans arrived on the Indian subcontinent from Africa no later than 55,000 years ago., "Y-Chromosome and Mt-DNA data support the colonization of South Asia by modern humans originating in Africa. ... Coalescence dates for most non-European populations average to between 73–55 ka.", "Modern human beings—''Homo sapiens''—originated in Africa. Then, int ...

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] |
Stainless Steel
Stainless steel is an alloy of iron that is resistant to rusting and corrosion. It contains at least 11% chromium and may contain elements such as carbon, other nonmetals and metals to obtain other desired properties. Stainless steel's corrosion resistance, resistance to corrosion results from the chromium, which forms a Passivation (chemistry), passive film that can protect the material and self-healing material, self-heal in the presence of oxygen. 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 chemicals and food products. The biological cleanability of stainless steel is superior to both alumi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 in ...

Rupee
Rupee is the common name for the currencies of India, Mauritius, Nepal, Pakistan, Seychelles, and Sri Lanka, and of former currencies of Afghanistan, Bahrain, Kuwait, Oman, the United Arab Emirates (as the Gulf rupee), British East Africa, Burma, German East Africa (as Rupie/Rupien), and Tibet. In Indonesia and the Maldives, the unit of currency is known as ''rupiah'' and ''rufiyaa'' respectively, cognates of the word rupee. The Indian rupees () and Pakistani rupees () are subdivided into one hundred paise (singular ''paisa'') or pice. The Nepalese rupee (रू) subdivides into one hundred paisa (singular and plural) or four sukaas. The Mauritian, Seychellois, and Sri Lankan rupees subdivide into 100 cents. Etymology The Hindustani word ''rupyā'' is derived from the Sanskrit word ''rūpya'' (), which means "wrought silver, a coin of silver", in origin an adjective meaning "shapely", with a more specific meaning of "stamped, impressed", whence "coin". It is derived f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
