ISO 4217
–
The ISO4217 code list is used in banking and business globally. ISO4217 codes are used on tickets and international train tickets to remove any ambiguity about the price. The first two letters of the code are the two letters of the ISO 3166-1 alpha-2 country codes and the third is usually the initial of the currency itself, so Japans currency code is JPY—JP for Japan and Y for yen. This eliminates the problem caused by the dollar, franc, peso and pound being used in dozens of different countries. Also, if a currency is revalued, the currency codes last letter is changed to distinguish it from the old currency. Other changes can be seen, however, the Russian ruble, for example, changed from RUR to RUB and these currency units are denominated as one troy ounce of the specified metal as opposed to USD1 or EUR1. The code XTS is reserved for use in testing, the code XXX is used to denote a transaction involving no currency. There are also codes specifying certain monetary instruments used in international finance, the codes for most supranational currencies, such as the East Caribbean dollar, the CFP franc, the CFA franc BEAC and the CFA franc BCEAO. The predecessor to the euro, the European Currency Unit, had the code XEU, the use of an initial letter X for these purposes is facilitated by the ISO3166 rule that no official country code beginning with X will ever be assigned. Because of this rule ISO4217 can use X codes without risk of clashing with a country code. ISO3166 country codes beginning with X are used for private custom use, consequently, ISO4217 can use X codes for non-country-specific currencies without risk of clashing with future country codes. The inclusion of EU in the ISO 3166-1 reserved codes list, the ISO4217 standard includes a crude mechanism for expressing the relationship between a major currency unit and its corresponding minor currency unit. This mechanism is called the exponent and assumes a base of 10. For example, USD is equal to 100 of its currency unit the cent. So the USD has exponent 2, the code JPY is given the exponent 0, because its minor unit, the sen, although nominally valued at 1/100 of a yen, is of such negligible value that it is no longer used. Usually, as with the USD, the currency unit has a value that is 1/100 of the major unit, but in some cases 1/1000 is used. Mauritania does not use a decimal division of units, setting 1 ouguiya equal to 5 khoums, some currencies do not have any minor currency unit at all and these are given an exponent of 0, as with currencies whose minor units are unused due to negligible value. There is also a code number assigned to each currency

Tetri
–
Tetri is a fractional currency used in the country of Georgia. It was put into circulation in 1995, the name tetri was adopted from the term describing golden, silver or copper coins known in ancient and medieval Georgia. The plural of the term tetri is tetrebi, however, the Georgian language uses the singular form when the quantity is specified, so in practice the plural of tetri is just tetri. Modern coins minted in the Republic of Georgia

Currency symbol
–
A currency symbol is a graphic symbol used as a shorthand for a currencys name, especially in reference to amounts of money. The European Commission considers the global recognition of the euro sign € part of its success, in 2009, India launched a public competition to replace the ₨ ligature it shared with neighbouring countries. It finalised its new symbol, ₹ on 15 July 2010. It is a blend of the Latin letter R with the Devanagari letter र, when writing currency amounts the location of the symbol varies by currency. Many currencies in the English-speaking world and Latin America, place it before the amount, the Cape Verdean escudo places its symbol in the decimal separator position. The usage of many European countries, such as France, Germany, the decimal separator also follows local countries standards. For instance, the United Kingdom often uses an interpunct as the point on price stickers. Commas or decimal points are common separators used in other countries, see decimal separator for information on international standards. Older currency symbols have evolved slowly, often from previous currencies, the dollar and peso symbols originated from the mark employed to denote the Spanish real de a ocho, whereas the pound and lira symbols evolved from an L standing for libra, a Roman pound of silver. Newly invented currencies and currencies adopting new symbols have symbolism closer to their adopter, the added center bar in the real sign is meant to symbolize stability. The new Indian rupee symbol, ₹, is a combination of Latin. There are also considerations, such as the perception of the business community. For a new symbol to be used, software to render it needs to be promulgated, the EU was criticized for not considering how the euro symbol would need to be customized to work in different fonts. The original design was exceptionally wide. These two factors have led to most typefaces employing customized, font-specific versions, usually with reduced width, List of currencies List of circulating currencies Currency Symbols

Georgia (country)
–
Georgia is a country in the Caucasus region of Eurasia. The capital and largest city is Tbilisi, Georgia covers a territory of 69,700 square kilometres, and its 2016 population is about 3.72 million. Georgia is a unitary, semi-presidential republic, with the government elected through a representative democracy, during the classical era, several independent kingdoms became established in what is now Georgia. The kingdoms of Colchis and Iberia adopted Christianity in the early 4th century, a unified Kingdom of Georgia reached the peak of its political and economic strength during the reign of King David IV and Queen Tamar in the 12th and early 13th centuries. Thereafter the kingdom declined and eventually disintegrated under hegemony of various powers, including the Mongols, the Ottoman Empire. Russian rule over Georgia was eventually acknowledged in various treaties with Iran. Since the establishment of the modern Georgian republic in April 1991, post-communist Georgia suffered from civil, the countrys Western orientation soon led to the worsening of relations with Russia, culminating in the brief Russo-Georgian War in August 2008. Georgia is a member of the United Nations, the Council of Europe, and it contains two de facto independent regions, Abkhazia and South Ossetia, which gained limited international recognition after the 2008 Russo-Georgian War. Georgia and a part of the international community consider the regions to be part of Georgias sovereign territory under Russian military occupation. Georgia probably stems from the Persian designation of the Georgians – gurğān, in the 11th and 12th centuries adapted via Syriac gurz-ān/gurz-iyān, starting with the Persian word gurğ/gurğān, the word was later adopted in numerous other languages, including Slavic and West European languages. This term itself might have established through the ancient Iranian appellation of the near-Caspian region. The self-designation used by ethnic Georgians is Kartvelebi, the medieval Georgian Chronicles present an eponymous ancestor of the Kartvelians, Kartlos, a great-grandson of Japheth. However, scholars agree that the word is derived from the Karts, the name Sakartvelo consists of two parts. Its root, kartvel-i, specifies an inhabitant of the core central-eastern Georgian region of Kartli, ancient Greeks and Romans referred to early western Georgians as Colchians and eastern Georgians as Iberians. Today the full, official name of the country is Georgia, before the 1995 constitution came into force the countrys name was the Republic of Georgia. The territory of modern-day Georgia was inhabited by Homo erectus since the Paleolithic Era, the proto-Georgian tribes first appear in written history in the 12th century BC. The earliest evidence of wine to date has found in Georgia. In fact, early metallurgy started in Georgia during the 6th millennium BC, the classical period saw the rise of a number of early Georgian states, the principal of which was Colchis in the west and Iberia in the east

Abkhazia
–
Abkhazia is a partially recognised state on the eastern coast of the Black Sea and the south-western flank of the Caucasus Mountains, south of Russia and northwest of Georgia proper. It covers 8,660 square kilometres and has a population of around 240,000, the separatist Abkhazian polity, formally the Republic of Abkhazia or Apsny, is recognised only by Russia and a small number of other countries. The status of Abkhazia is an issue of the Georgian–Abkhazian conflict. The region enjoyed autonomy within Soviet Georgia at the time when the Soviet Union began to disintegrate in the late 1980s, despite the 1994 ceasefire agreement and years of negotiations, the dispute remained unresolved. The long-term presence of a United Nations Observer Mission and a Russian-led Commonwealth of Independent States peacekeeping force failed to prevent the flare-up of violence on several occasions. On 28 August 2008, the Parliament of Georgia declared Abkhazia a Russian-occupied territory, the Abkhazians call their homeland Аҧсны, popularly etymologised as a land/country of the soul, yet literally meaning a country of mortals. It possibly first appeared in the century in an Armenian text as Psin. The state is designated as the Republic of Abkhazia or Apsny. The Russian Абхазия is adapted from the Georgian აფხაზეთი, in Mingrelian, Abkhazia is known as აბჟუა or სააფხაზო. Between the 9th and 6th centuries BC, the territory of modern Abkhazia was part of the ancient Georgian kingdom of Colchis and this kingdom was subsequently absorbed in 63 BC into the Kingdom of Egrisi, known to Byzantine Roman sources as Lazica. Classical authors described various peoples living in the region and the multitude of languages they spoke. Arrian, Pliny and Strabo have given accounts of the Abasgoi and Moschoi peoples somewhere in modern Abkhazia on the shore of the Black Sea. Around the mid 6th century AD, the Byzantines and the neighbouring Sassanid Persia fought for supremacy over Abkhazia for 20 years, Abkhazia, or Abasgia in classic sources, formerly part of Colchis and later of Egrisi until the late 690s, was a princedom under Byzantine authority. The country was mostly Christian, with the seat in Pityus. An Arab incursion into Abkhazia led by Marwan II, was repelled by Leon I jointly with his Egrisian and Kartlian allies in 736, after acquiring Egrisi via a dynastic union in the 780s the Kingdom of Abkhazia was established and became a dominant power in western Caucasus. During this period the Georgian language replaced Greek as the language of literacy, the western Georgian kingdom flourished between 850 and 950 when it annexed significant parts of central Georgia. In the 16th century, after the break-up of the Georgian Kingdom into small kingdoms and principalities, since the 1570s, when the Ottoman navy occupied the fort of Tskhumi, Abkhazia came under the influence of the Ottoman Empire and Islam. Under Ottoman rule, the majority of Abkhaz elite converted to Islam, the principality retained a degree of autonomy

South Ossetia
–
It has a population of 53,000 people which live in an area of 3,900 km2, south of the Russian Caucasus, with 30,000 living in its capital city of Tskhinvali. South Ossetia declared independence from the Georgian Soviet Socialist Republic in 1991, the Georgian government responded by abolishing South Ossetias autonomy and trying to re-establish its control over the region by force. The crisis escalation led to the 1991–92 South Ossetia War, Georgian fighting against those controlling South Ossetia occurred on two other occasions, in 2004 and 2008. The latter conflict led to the Russo–Georgian War, during which Ossetian and Russian forces gained full de facto control of the territory of the former South Ossetian Autonomous Oblast. In the wake of the 2008 war, Russia, followed by Nicaragua, Venezuela, Georgia and a significant part of the international community consider South Ossetia to be occupied by the Russian military. South Ossetia relies heavily on military, political and financial aid from Russia, Russia does not allow European Union Monitoring Mission monitors to enter South Ossetia. South Ossetia, Transnistria, Nagorno-Karabakh, and Abkhazia are sometimes referred to as post-Soviet frozen conflict zones, the Ossetians are believed to originate from the Alans, a Sarmatian Iranian tribe. In the 17th century, Ossetians started migration from the North Caucasus to Georgia, Ossetian peasants, who were migrating to the mountainous areas of the South Caucasus, often settled in the lands of Georgian feudal lords. The Georgian King of the Kingdom of Kartli permitted Ossetians to immigrate, in the 1770s there were more Ossetians living in Kartli than ever before. This period has been documented in the diaries of Johann Anton Güldenstädt who visited Georgia in 1772. The Baltic German explorer called modern North Ossetia simply Ossetia, while he wrote that Kartli was populated by Georgians, Güldenstädt also wrote that the northernmost border of Kartli is the Major Caucasus Ridge. The Georgian Kingdom of Kartli-Kakheti, part of which was the territory of modern South Ossetia, was annexed by the Russian Empire in 1801. Following the Russian revolution, the area of modern South Ossetia became part of the Democratic Republic of Georgia, although the Ossetians were initially discontented with the economic policies of the central government, the tension soon transformed into ethnic conflict. The first Ossetian rebellion began in February 1918, when three Georgian princes were killed and their land was seized by the Ossetians, the central government of Tiflis retaliated by sending the National Guard to the area. However, the Georgian unit retreated after they had engaged the Ossetians, Ossetian rebels then proceeded to occupy the town of Tskhinvali and began attacking ethnic Georgian civilian population. During uprisings in 1919 and 1920, the Ossetians were covertly supported by Soviet Russia, but even so, were defeated. Between 3,000 and 7,000 Ossetians were killed during the crushing of the 1920 uprising, according to Ossetian sources ensuing hunger, the drawing of administrative boundaries of the South Ossetian AO was quite a complicated process. Many Georgian villages were included within the South Ossetian AO despite numerous protests by the Georgian population, while the city of Tskhinvali did not have a majority Ossetian population, it was made the capital of the South Ossetian AO

Central bank
–
A central bank, reserve bank, or monetary authority is an institution that manages a states currency, money supply, and interest rates. Central banks also usually oversee the commercial banking system of their respective countries, Central banks in most developed nations are institutionally designed to be independent from political interference. Still, limited control by the executive and legislative bodies usually exists, prior to the 17th century most money was commodity money, typically gold or silver. However, promises to pay were widely circulated and accepted as value at least five hundred years earlier in both Europe and Asia. The Song dynasty was the first to issue generally circulating paper currency, in 1455, in an effort to control inflation, the succeeding Ming Dynasty ended the use of paper money and closed much of Chinese trade. The Bank of Amsterdam, established in the Dutch Republic in 1609, is considered to be the forerunner to modern central banks. The Wisselbanks innovations helped lay the foundations for the birth and development of the banking system that now plays a vital role in the worlds economy. Along with a number of local banks, it performed many functions of a central banking system. Lucien Gillard calls it the European guilder, and Adam Smith devotes many pages to explaining how the bank guilder works, the model of the Wisselbank as a state bank was adapted throughout Europe, including the Bank of Sweden and the Bank of England. Established by Dutch-Latvian Johan Palmstruch in 1668, Sveriges Riksbank is often considered by many as the worlds oldest central bank, the lenders would give the government cash and also issue notes against the government bonds, which could be lent again. A Royal Charter was granted on 27 July through the passage of the Tonnage Act 1694, the bank was given exclusive possession of the governments balances, and was the only limited-liability corporation allowed to issue banknotes. The £1. 2M was raised in 12 days, half of this was used to rebuild the Navy and these modern central banking functions evolved slowly through the 18th and 19th centuries. The currency crisis of 1797, caused by panicked depositors withdrawing from the Bank led to the government suspending convertibility of notes into specie payment. The bank was accused by the bullionists of causing the exchange rate to fall from over issuing banknotes. Nevertheless, it was clear that the Bank was being treated as an organ of the state, henry Thornton, a merchant banker and monetary theorist has been described as the father of the modern central bank. An opponent of the real bills doctrine, he was a defender of the bullionist position, thorntons process of monetary expansion anticipated the theories of Knut Wicksell regarding the cumulative process which restates the Quantity Theory in a theoretically coherent form. Until the mid-nineteenth century, commercial banks were able to issue their own banknotes, many consider the origins of the central bank to lie with the passage of the Bank Charter Act of 1844. Under this law, authorisation to issue new banknotes was restricted to the Bank of England, at the same time, the Bank of England was restricted to issue new banknotes only if they were 100% backed by gold or up to £14 million in government debt

Currency
–
A currency in the most specific use of the word refers to money in any form when in actual use or circulation as a medium of exchange, especially circulating banknotes and coins. A more general definition is that a currency is a system of money in common use, under this definition, US dollars, British pounds, Australian dollars, and European euros are examples of currency. These various currencies are recognized stores of value and are traded between nations in exchange markets, which determine the relative values of the different currencies. Currencies in this sense are defined by governments, and each type has limited boundaries of acceptance, other definitions of the term currency are discussed in their respective synonymous articles banknote, coin, and money. The latter definition, pertaining to the systems of nations, is the topic of this article. Currencies can be classified into two systems, fiat money and commodity money, depending on what guarantees the value. Some currencies are legal tender in certain jurisdictions, which means they cannot be refused as payment for debt. Others are simply traded for their economic value, digital currency has arisen with the popularity of computers and the Internet. Currency evolved from two basic innovations, both of which had occurred by 2000 BC, originally money was a form of receipt, representing grain stored in temple granaries in Sumer in ancient Mesopotamia, then Ancient Egypt. In this first stage of currency, metals were used as symbols to represent value stored in the form of commodities and this formed the basis of trade in the Fertile Crescent for over 1500 years. Trade could only reach as far as the credibility of that military and it is not known what was used as a currency for these exchanges, but it is thought that ox-hide shaped ingots of copper, produced in Cyprus, may have functioned as a currency. It is thought that the increase in piracy and raiding associated with the Bronze Age collapse, possibly produced by the Peoples of the Sea, brought the trading system of oxhide ingots to an end. In Africa, many forms of value store have been used, including beads, ingots, ivory, various forms of weapons, livestock, the manilla currency, the manilla rings of West Africa were one of the currencies used from the 15th century onwards to sell slaves. African currency is still notable for its variety, and in many various forms of barter still apply. These factors led to the metal itself being the store of value, first silver, now we have copper coins and other non-precious metals as coins. Metals were mined, weighed, and stamped into coins and this was to assure the individual taking the coin that he was getting a certain known weight of precious metal. Coins could be counterfeited, but they created a new unit of account. Most major economies using coinage had several tiers of coins, using a mix of copper, silver, gold coins were used for large purchases, payment of the military and backing of state activities, they were more often used as measures of account than physical coins

Colchis
–
Colchis was an ancient kingdom and region on the coast of the Black Sea, centered in present-day western Georgia. Internationally, Colchis is perhaps best known for its role in Greek mythology, most notably as the destination of the Argonauts, as well as the home to Medea and the Golden fleece. Colchis was populated by Colchians, an early Kartvelian-speaking tribe, ancestral to the contemporary Western Georgians, namely Svans and Mingrelians, the kingdom of Colchis, Kolkhis or Qulha which existed from the c. According to the scholar of Caucasian studies Cyril Toumanoff, Colchis appears as the first Caucasian State to have achieved the coalescence of the newcomer. Colchis can be regarded as not a proto-Georgian, but a Georgian kingdom. It would seem natural to seek the beginnings of Georgian social history in Colchis. A second South Caucasian tribal union emerged in the 13th century BC on the Black Sea coast. There is some difference in authors as to the extent of the country westward, thus Strabo makes Colchis begin at Trabzon, while Ptolemy, on the other hand. The name of Colchis first appears in Aeschylus and Pindar, the earlier writers only speak about it under the name of Aea, the residence of the mythical king Aeëtes, Kolchian Aia lies at the furthest limits of sea and earth, wrote Apollonius of Rhodes. Scylax mentions also Mala or Male, which he, in contradiction to other writers, the central part of the region is Colchis Plain, stretching between Sokhumi and Kobuleti, most of that lies on the elevation below 20 m above sea level. Marginal parts of the region are mountains of the Great and the Lesser Caucasus, the climate is mild humid, near Batumi, annual rainfall level reaches 4,000 mm, which is the absolute maximum for the continental western Eurasia. The dominating natural landscapes of Colchis are temperate rainforests, yet degraded in the part of the region, wetlands. In at least some parts of Colchis, the process of urbanization seems to have been advanced by the end of the 2nd millennium BC. The Colchian Late Bronze Age saw the development of significant skill in the smelting and casting of metals, sophisticated farming implements were made, and fertile, well-watered lowlands and a mild climate promoted the growth of progressive agricultural techniques. Colchis was inhabited by a number of related but distinct tribes whose settlements lay along the shore of the Black Sea and these Colchian tribes differed so completely in language and appearance from the surrounding Indo-European nations that the ancients provided various wild theories to account for the phenomenon. Herodotus regarded the Colchians as Ancient Egyptian race, Apollonius of Rhodes states that the Egyptians of Colchis preserved as heirlooms a number of wooden tablets, which show, with considerable accuracy, seas and highways. Detlev Fehling regards the link between Colchis and Egypt as a clear example of the way Herodotus used spurious sources to back up stories he had made up himself. In the 13th century BC, the Kingdom of Colchis was formed as a result of the consolidation of the tribes inhabiting the region. This power, celebrated in Greek mythology as the destination of the Argonauts, the home of Medea, the kingdom of Tabal was conquered by the Assyrian emperor Shalmaneser III in the 830s BC

Georgian abazi
–
Abazi was a Georgian silver coin, deriving its name and existence from the Iranian abbasi, which was in use from the early 17th century into the early 19th. The name abazi derives from the Persian abbasi, a coin first issued by the Safavid shah Abbas I. It was subdivided into 200 dinar, other denominations were the puli of 5 dinar and the bisti of 20 dinar. These abazi coins at first weighed 7.8 grams but by the end of the 18th century their weight reportedly declined to just 3 grams. Coins featured, except the Islamic profession of faith and/or the names of the Shiite Imams on the front, the name of the Persian shah, after the absorption of Georgia into the Russian Empire in 1801, the currency was not immediately replaced by the Russian ruble. Instead, an issue of coins was made between 1804 and 1833 in denominations of 5,10 and 20 dinar in copper and 100,200 and 400 dinar in silver. These were related to the Russian currency at a rate of 10 dinar to the kopeck, the Russian ruble was introduced in 1833 at a rate of 5 abazi =1 ruble. However, the Georgian coins continued to circulate into the 1860s

Russian ruble
–
The Russian ruble is the currency of the Russian Federation, the two partially recognized republics of Abkhazia and South Ossetia, and the two unrecognized republics of Donetsk and Luhansk. The ruble is subdivided into 100 kopeks, the ruble was the currency of the Russian Empire and of the Soviet Union. Today apart from Russia, Belarus and Transnistria uses currencies with the same name, the ruble was the worlds first decimal currency, it was decimalised in 1704 when the ruble became legally equal to 100 kopeks. In 1992 the Soviet ruble was replaced with the Russian ruble at the rate 1 SUR =1 RUR. In 1998 following the crisis, the Russian ruble was redenominated with the new code RUB. Today, although RUB being the code of the Russian ruble. The ruble is the oldest national currency after the Pound sterling in the world, the ruble has been used on the Russian territories since the 13th century. The modern Russian ruble actually appeared in December 1991 in parallel with the Soviet ruble, following the breakup of the Soviet Union in 1991, the Soviet ruble remained the currency of the Russian Federation until 1992. A new set of coins was issued in 1992 and a new set of banknotes was issued in the name of Bank of Russia in 1993. The Russian ruble with the ISO4217 code is RUR and number 810 replaced the Soviet ruble at the rate 1 SUR =1 RUR. After the fall of the Soviet Union, the Russian Federation introduced new coins in 1992 in denominations of 1,5,10,20,50 and 100 rubles, the coins depict the double-headed eagle without a crown, sceptre and globus cruciger above the legend Банк России. It is exactly the same eagle, that the artist Ivan Bilibin painted after the February Revolution as a coat of arms for the Russian Republic. The 1 and 5 ruble coins were minted in brass-clad steel, the 10 and 20 ruble coins in cupro-nickel, in 1993, aluminium-bronze 50 ruble coins and cupro-nickel-zinc 100 ruble coins were issued, and the material of 10 and 20 ruble coins s was changed to nickel-plated steel. In 1995 the material of 50 ruble coins was changed to brass-plated steel, as high inflation persisted, the lowest denominations disappeared from circulation and the other denominations became rarely used. During this period the commemorative one ruble coin was regularly issued and it was practically identical in size and weight to a 5 Swiss franc coin. For this reason, there have been instances of ruble coins being used on a large scale to defraud automated vending machines in Switzerland. In 1961, new State Treasury notes were introduced for 1,3 and 5 rubles, along with new State Bank notes for 10,25,50 and 100 rubles. In 1991, the State Bank took over production of 1,3 and 5 ruble notes and also introduced 200,500 and 1,000 ruble notes, although the 25 ruble note was no longer issued

Hyperinflation
–
Certain figures in this article use scientific notation for readability. The population normally switches to holding relatively stable foreign currencies, under such conditions, the general price level within an economy increases rapidly as the official currency quickly loses real value. The value of economic items remains relatively stable in terms of foreign currencies, typically, however, the general price level rises even more rapidly than the money supply as people try ridding themselves of the devaluing currency as quickly as possible. As this scenario happens, the stock of money decreases. The mainstream narrative is that hyperinflations are usually caused by large persistent government deficits financed primarily by money creation, as such, hyperinflation is often associated with wars, their aftermath, sociopolitical upheavals, or other crises that make it difficult for the government to tax the population. A sharp decrease in tax revenue coupled with a strong need to maintain the status quo, together with an inability or unwillingness to borrow. The mainstream assumptions of how hyperinflation is caused has been challenged by advocates of Modern Monetary Theory who sustain that government spending alone cannot cause hyperinflation. They claim that hyperinflation is usually the result of a collapse in the supply chain which is then unable to meet the demand generated by government spending. In 1956, Phillip Cagan wrote The Monetary Dynamics of Hyperinflation, economists usually follow Cagan’s description that hyperinflation occurs when the monthly inflation rate exceeds 50%. The International Accounting Standards Board has issued guidance on accounting rules in a hyperinflationary environment and it does not establish an absolute rule on when hyperinflation arises. Instead, it lists factors that indicate the existence of hyperinflation, there are a number of theories on the causes of high and/or hyper inflation. But nearly all hyperinflations have been caused by government budget deficits financed by money creation, after an analysis of 29 hyperinflations Bernholz concludes that at least 25 of them have been caused in this way. Moreover, a condition for hyperinflation has been the existence of fiat money not convertible at a fixed parity into gold or silver. The French hyperinflation also took place after the introduction of a non convertible paper money, the price increases that result from the rapid money creation creates a vicious circle, requiring ever growing amounts of new money creation to fund government deficits. Hence both monetary inflation and price inflation proceed at a rapid pace, such rapidly increasing prices cause widespread unwillingness of the local population to hold the local currency as it rapidly loses its buying power. Instead they quickly spend any money they receive, which increases the velocity of money flow and this means that the increase in the price level is greater than that of the money supply. The real stock of money, M/P, decreases, here M refers to the money stock and P to the price level. This results in an imbalance between the supply and demand for the money, causing rapid inflation, very high inflation rates can result in a loss of confidence in the currency, similar to a bank run

Eduard Shevardnadze
–
Eduard Ambrosiyevich Shevardnadze was a Georgian politician and diplomat. He served as First Secretary of the Georgian Communist Party, the de facto leader of Soviet Georgia from 1972 to 1985, Shevardnadze was responsible for many key decisions in Soviet foreign policy during the Gorbachev Era. Following the dissolution of the Soviet Union, he was President of Georgia from 1992 to 2003 and he was forced to retire in 2003 as a consequence of the bloodless Rose Revolution. Shevardnadze started his career in the late 1940s as a leading member of his local Komsomol organisation. He was later appointed its Second Secretary, then its First Secretary and his rise in the Georgian Soviet hierarchy continued until 1961 when he was demoted after he insulted a senior official. After spending two years in obscurity, Shevardnadze returned as a First Secretary of a Tbilisi city district and his anti-corruption work quickly garnered the interest of the Soviet government and Shevardnadze was appointed as First Deputy of the Ministry of Internal Affairs of the Georgian SSR. He would later become the head of the internal affairs ministry and was able to charge First Secretary Vasil Mzhavanadze with corruption, Shevardnadzes anti-corruption campaign continued until he resigned from his office as First Secretary. Mikhail Gorbachev appointed Shevardnadze to the post of Minister of Foreign Affairs, from then on, with the exception of a brief period between 1990 and 1991, only Gorbachev would outrank Shevardnadze in importance in Soviet foreign policy. In the aftermath of the Soviet Unions collapse in 1991, Shevardnadze returned to the newly independent Georgia and he became the countrys head of state following the removal of the countrys first president, Zviad Gamsakhurdia. Shevardnadze was formally elected president in 1995 and his presidency was marked by rampant corruption and accusations of nepotism. He later lived in obscurity and published his memoirs. Eduard Shevardnadze was born in Mamati in the Transcaucasian SFSR, Soviet Union, on 25 January 1928 and his father Ambrose was a teacher and a devoted communist and party official. His mother had little respect for the communist government and opposed both Shevardnadzes and his fathers party careers, eduard was a cousin of the Georgian painter and intellectual Dimitri Shevardnadze, who was purged during Stalinist repressions. In 1948 at the age of twenty, Shevardnadze joined the Georgian Communist Party and he rose steadily through the ranks of the Georgian Komsomol and after serving a term as Second Secretary, he became its First Secretary. During his Komsomol First Secretaryship, Shevardnadze met Mikhail Gorbachev for his first time, Shevardnadze said he grew disillusioned with the Soviet political system following Nikita Khrushchevs Secret Speech to the 20th CPSU Congress. Like many Soviet people, the crimes perpetrated by Joseph Stalin horrified Shevardnadze, and he was demoted in 1961 by the Politburo of the Georgian Communist Party after offending a senior official. After his demotion Shevardnadze endured several years of obscurity before returning to attention as a First Secretary of a city district in Tbilisi, Shevardnadze challenged Tbilisi First Secretary Otari Lolashvili, and later charged him for corruption. Shevardnadze left party work after his appointment as First Deputy of the Ministry of Internal Affairs of the Georgian SSR in 1964 and it was his successful attempt at gaoling Lolashvili, which got him promoted to the post of First Deputyship

Specials is a short Unicode block allocated at the very end of the Basic Multilingual Plane, at U+FFF0–FFFF. Of these 16 codepoints, five are assigned as of Unicode 9, U+FFFD � REPLACEMENT CHARACTER used to replace an unknown, unrecognized or unrepresentable character U+FFFE <noncharacter-FFFE> not a character. FFFE and FFFF are not unassigned in the sense. They can be used to guess a texts encoding scheme, since any text containing these is by not a correctly encoded Unicode text. The replacement character � is a found in the Unicode standard at codepoint U+FFFD in the Specials table. It is used to indicate problems when a system is unable to render a stream of data to a correct symbol and it is usually seen when the data is invalid and does not match any character, Consider a text file containing the German word für in the ISO-8859-1 encoding. This file is now opened with an editor that assumes the input is UTF-8. The first and last byte are valid UTF-8 encodings of ASCII, therefore, a text editor could replace this byte with the replacement character symbol to produce a valid string of Unicode code points. The whole string now displays like this, f�r, a poorly implemented text editor might save the replacement in UTF-8 form, the text file data will then look like this, 0x66 0xEF 0xBF 0xBD 0x72, which will be displayed in ISO-8859-1 as f�r. Since the replacement is the same for all errors this makes it impossible to recover the original character, a better design is to preserve the original bytes, including the error, and only convert to the replacement when displaying the text. This will allow the text editor to save the original byte sequence and it has become increasingly common for software to interpret invalid UTF-8 by guessing the bytes are in another byte-based encoding such as ISO-8859-1. This allows correct display of both valid and invalid UTF-8 pasted together, Unicode control characters UTF-8 Mojibake Unicodes Specials table Decodeunicodes entry for the replacement character

Unicode
–
Unicode is a computing industry standard for the consistent encoding, representation, and handling of text expressed in most of the worlds writing systems. As of June 2016, the most recent version is Unicode 9.0, the standard is maintained by the Unicode Consortium. Unicodes success at unifying character sets has led to its widespread, the standard has been implemented in many recent technologies, including modern operating systems, XML, Java, and the. NET Framework. Unicode can be implemented by different character encodings, the most commonly used encodings are UTF-8, UTF-16 and the now-obsolete UCS-2. UTF-8 uses one byte for any ASCII character, all of which have the same values in both UTF-8 and ASCII encoding, and up to four bytes for other characters. UCS-2 uses a 16-bit code unit for each character but cannot encode every character in the current Unicode standard, UTF-16 extends UCS-2, using one 16-bit unit for the characters that were representable in UCS-2 and two 16-bit units to handle each of the additional characters. Many traditional character encodings share a common problem in that they allow bilingual computer processing, Unicode, in intent, encodes the underlying characters—graphemes and grapheme-like units—rather than the variant glyphs for such characters. In the case of Chinese characters, this leads to controversies over distinguishing the underlying character from its variant glyphs. In text processing, Unicode takes the role of providing a unique code point—a number, in other words, Unicode represents a character in an abstract way and leaves the visual rendering to other software, such as a web browser or word processor. This simple aim becomes complicated, however, because of concessions made by Unicodes designers in the hope of encouraging a more rapid adoption of Unicode, the first 256 code points were made identical to the content of ISO-8859-1 so as to make it trivial to convert existing western text. For other examples, see duplicate characters in Unicode and he explained that he name Unicode is intended to suggest a unique, unified, universal encoding. In this document, entitled Unicode 88, Becker outlined a 16-bit character model, Unicode could be roughly described as wide-body ASCII that has been stretched to 16 bits to encompass the characters of all the worlds living languages. In a properly engineered design,16 bits per character are more than sufficient for this purpose, Unicode aims in the first instance at the characters published in modern text, whose number is undoubtedly far below 214 =16,384. By the end of 1990, most of the work on mapping existing character encoding standards had been completed, the Unicode Consortium was incorporated in California on January 3,1991, and in October 1991, the first volume of the Unicode standard was published. The second volume, covering Han ideographs, was published in June 1992, in 1996, a surrogate character mechanism was implemented in Unicode 2.0, so that Unicode was no longer restricted to 16 bits. The Microsoft TrueType specification version 1.0 from 1992 used the name Apple Unicode instead of Unicode for the Platform ID in the naming table, Unicode defines a codespace of 1,114,112 code points in the range 0hex to 10FFFFhex. Normally a Unicode code point is referred to by writing U+ followed by its hexadecimal number, for code points in the Basic Multilingual Plane, four digits are used, for code points outside the BMP, five or six digits are used, as required. Code points in Planes 1 through 16 are accessed as surrogate pairs in UTF-16, within each plane, characters are allocated within named blocks of related characters

Georgian scripts
–
The Georgian scripts are the three writing systems used to write the Georgian language, Asomtavruli, Nuskhuri and Mkhedruli. Although the systems differ in appearance, all three are unicase, their letters share the names and alphabetical order, and are written horizontally from left to right. Of the three scripts, Mkhedruli was the civilian royal script of the Kingdom of Georgia mostly used for the royal charters, originally consisting of 38 letters, Georgian is presently written in a 33-letter alphabet, as five letters are currently obsolete in that language. The number of Georgian letters used in other Kartvelian languages varies, the Mingrelian language uses 36,33 of which are current Georgian letters, one obsolete Georgian letter, and two additional letters specific to Mingrelian and Svan. That same obsolete letter, plus a letter borrowed from Greek, are used in writing the Laz language, Georgian scripts were granted the national status of cultural heritage in Georgia in 2015 and inscribed on the UNESCO Representative List of the Intangible Cultural Heritage of Humanity in 2016. The first version of the script attested is Asomtavruli which dates back to at least the 5th century, most scholars link the creation of the Georgian script to the process of Christianization of Iberia, a core Georgian kingdom of Kartli. The alphabet was therefore most probably created between the conversion of Iberia under King Mirian III and the Bir el Qutt inscriptions of 430 and it was first used for translation of the Bible and other Christian literature into Georgian, by monks in Georgia and Palestine. This account is now considered legendary, and is rejected by scholarly consensus, a point of contention among scholars is the role played by Armenian clerics in that process. Other scholars quote Koryuns claims without taking a stance on its validity, many agree, however, that Armenian clerics, if not Mashtots himself, must have played a role in the creation of the Georgian script. Another controversy regards the main influences at play in the Georgian alphabet, as scholars have debated whether it was inspired more by the Greek alphabet, or by Semitic alphabets such as Aramaic. Recent historiography focuses on greater similarities with the Greek alphabet than in the other Caucasian writing systems, most notably the order, some scholars have also suggested as a possible inspiration for particular letters certain pre-Christian Georgian cultural symbols or clan markers. Asomtavruli is the oldest Georgian script, the name Asomtavruli means capital letters, from aso letter and mtavari principal/head. It is also known as Mrgvlovani rounded, from mrgvali round, despite its name, this capital script is unicameral, just like the modern Georgian script, Mkhedruli. The oldest Asomtavruli inscriptions found so far date from the 5th century and are Bir el Qutt, from the 9th century, Nuskhuri script starting becoming dominant, and the role of Asomtavruli was reduced. However, epigraphic monuments of the 10th to 18th centuries continued to be written in Asomtavruli script, Asomtavruli in this later period became more decorative. In the majority of 9th-century Georgian manuscripts which were written in Nuskhuri script, Asomtavruli was used for titles, although, some manuscripts written completely in Asomtavruli can be found until the 11th century. In early Asomtavruli, the letters are of equal height, in most Asomtavruli letters, straight lines are horizontal or vertical and meet at right angles. The only letter with acute angles is Ⴟ, there have been various attempts to explain this exception

Lasi (letter)
–
Lasi is the 12th letter of the three Georgian scripts. In the system of Georgian numerals it has a value of 30, lasi commonly represents the alveolar lateral approximant /l/, like the pronunciation of ⟨l⟩ in lord. Mkhedruli ლ is a symbol for Georgian lari. The restored Georgian alphabet, Fulda, Germany,2013 Mchedlidze, T

Stainless steel
–
In metallurgy, stainless steel, also known as inox steel or inox from French inoxydable, is a steel alloy with a minimum of 10. 5% chromium content by mass. Stainless steel is notable for its resistance, and it is widely used for food handling. Stainless steel does not readily corrode, rust or stain with water as ordinary steel does, however, it is not fully stain-proof in low-oxygen, high-salinity, or poor air-circulation environments. There are various grades and surface finishes of stainless steel to suit the environment the alloy must endure, Stainless steel is used where both the properties of steel and corrosion resistance are required. Stainless steel differs from carbon steel by the amount of chromium present, unprotected carbon steel rusts readily when exposed to air and moisture. This iron oxide film is active and accelerates corrosion by making it easier for more iron oxide to form, since iron oxide has lower density than steel, the film expands and tends to flake and fall away. In comparison, stainless steels contain sufficient chromium to undergo passivation and this layer prevents further corrosion by blocking oxygen diffusion to the steel surface and stops corrosion from spreading into the bulk of the metal. Passivation occurs only if the proportion of chromium is high enough, Stainless steel’s resistance to corrosion and staining, low maintenance, and familiar lustre make it an ideal material for many applications. Storage tanks and tankers used to transport orange juice and other food are made of stainless steel. This also influences its use in kitchens and food processing plants, as it can be steam-cleaned and sterilized. High oxidation resistance in air at ambient temperature is achieved with addition of a minimum of 13% chromium. The chromium forms a layer of chromium oxide when exposed to oxygen. The layer is too thin to be visible, and the metal remains lustrous, the layer is impervious to water and air, protecting the metal beneath, and this layer quickly reforms when the surface is scratched. This phenomenon is called passivation and is seen in other metals, corrosion resistance can be adversely affected if the component is used in a non-oxygenated environment, a typical example being underwater keel bolts buried in timber. When stainless steel parts such as nuts and bolts are forced together, when forcibly disassembled, the welded material may be torn and pitted, a destructive effect known as galling. Galling can be avoided by the use of materials for the parts forced together, for example bronze and stainless steel. However, two different alloys electrically connected in a humid, even mildly acidic environment may act as a voltaic pile, nitronic alloys, made by selective alloying with manganese and nitrogen, may have a reduced tendency to gall. Additionally, threaded joints may be lubricated to provide a film between the two parts and prevent galling, low-temperature carburizing is another option that virtually eliminates galling and allows the use of similar materials without the risk of corrosion and the need for lubrication

Borjgali
–
Borjgali is a Georgian symbol of the Sun with seven rotating wings over the Christian Tree of Life and is related to the Mesopotamian symbols of eternity. It is also related to the Triskelion, another symbol of eternity. It is usually depicted within the circle symbolizes the Universe. The roots of the Tree go into the past and its branches are for the future. The Tree itself symbolizes the continuity between past, present and the future, the Borjgali is usually placed above the tree and symbolizes the Sun, eternal movement and life. The term Borjgali is believed to derive from Megrelian word ბარჩხალი, some other scholars believe that it has different origins. In old Megrelian borj means time and gal means pass or flow, so the whole phrase would mean the flow of time. Nowadays, the symbol is used in Georgian IDs and passports, as well as on currency, Georgian rugby team players are called ბორჯღალოსნები, which means Men bearing Borjgali

Sun
–
The Sun is the star at the center of the Solar System. It is a perfect sphere of hot plasma, with internal convective motion that generates a magnetic field via a dynamo process. It is by far the most important source of energy for life on Earth. Its diameter is about 109 times that of Earth, and its mass is about 330,000 times that of Earth, accounting for about 99. 86% of the total mass of the Solar System. About three quarters of the Suns mass consists of hydrogen, the rest is mostly helium, with smaller quantities of heavier elements, including oxygen, carbon, neon. The Sun is a G-type main-sequence star based on its spectral class and it formed approximately 4.6 billion years ago from the gravitational collapse of matter within a region of a large molecular cloud. Most of this matter gathered in the center, whereas the rest flattened into a disk that became the Solar System. The central mass became so hot and dense that it eventually initiated nuclear fusion in its core and it is thought that almost all stars form by this process. The Sun is roughly middle-aged, it has not changed dramatically for more than four billion years and it is calculated that the Sun will become sufficiently large enough to engulf the current orbits of Mercury, Venus, and probably Earth. The enormous effect of the Sun on Earth has been recognized since prehistoric times, the synodic rotation of Earth and its orbit around the Sun are the basis of the solar calendar, which is the predominant calendar in use today. The English proper name Sun developed from Old English sunne and may be related to south, all Germanic terms for the Sun stem from Proto-Germanic *sunnōn. The English weekday name Sunday stems from Old English and is ultimately a result of a Germanic interpretation of Latin dies solis, the Latin name for the Sun, Sol, is not common in general English language use, the adjectival form is the related word solar. The term sol is used by planetary astronomers to refer to the duration of a solar day on another planet. A mean Earth solar day is approximately 24 hours, whereas a mean Martian sol is 24 hours,39 minutes, and 35.244 seconds. From at least the 4th Dynasty of Ancient Egypt, the Sun was worshipped as the god Ra, portrayed as a falcon-headed divinity surmounted by the solar disk, and surrounded by a serpent. In the New Empire period, the Sun became identified with the dung beetle, in the form of the Sun disc Aten, the Sun had a brief resurgence during the Amarna Period when it again became the preeminent, if not only, divinity for the Pharaoh Akhenaton. The Sun is viewed as a goddess in Germanic paganism, Sól/Sunna, in ancient Roman culture, Sunday was the day of the Sun god. It was adopted as the Sabbath day by Christians who did not have a Jewish background, the symbol of light was a pagan device adopted by Christians, and perhaps the most important one that did not come from Jewish traditions

Tree of life
–
The concept of a tree of life is a widespread mytheme or archetype in the worlds mythologies, related to the concept of sacred tree more generally, and hence in religious and philosophical tradition. The expression Tree of Life was used as a metaphor for the tree of common descent in the evolutionary sense in a famous passage by Charles Darwin. Various trees of life are recounted in folklore, culture and fiction and they had their origin in religious symbolism. The Eternal Banyan Tree is located on the bank of the Yamuna inside the courtyard of Allahabad Fort near the confluence of the Yamuna, the eternal and divine nature of this tree has been documented at length in the scriptures. During the cyclic destruction of creation when the earth was enveloped by waters. It is on the leaves of tree that Lord Krishna rested in the form of a baby when land was no longer visible. And it is here that the sage, Markandeya, received the cosmic vision of the Lord. It is under this tree that Buddha meditates eternally, legend also has it that the Bodi tree at Gaya is a manifestation of this tree. In pre-Islamic Persian mythology, the Gaokerena world tree is a large, ahriman created a frog to invade the tree and destroy it, aiming to prevent all trees from growing on the earth. As a reaction, God created two kar fish staring at the frog to guard the tree, the two fishes are always staring at the frog and stay ready to react to it. The sacred plant haoma and the drink made from it, the preparation of the drink from the plant by pounding and the drinking of it are central features of Zoroastrian ritual. Haoma is also personified as a divinity and it bestows essential vital qualities—health, fertility, husbands for maidens, even immortality. The source of the haoma plant is a shining white tree that grows on a paradisiacal mountain. Sprigs of this white haoma were brought to earth by divine birds, Haoma is the Avestan form of the Sanskrit soma. The near identity of the two in ritual significance is considered by scholars to point to a salient feature of an Indo-Iranian religion antedating Zoroastrianism. Another related issue in ancient mythology of Iran is the myth of Mashyа and Mashyane and this myth can be considered as a prototype for the creation myth where living beings are created by Gods. To the Ancient Egyptians, the Tree of Life represented the hierarchical chain of events that brought everything into existence, the spheres of the Tree of Life demonstrate the order, process, and method of creation. In Egyptian mythology, in the Ennead system of Heliopolis, the first couple, apart from Shu and Tefnut and Geb and Nut, are Isis and Osiris

Vine
–
A vine in the narrowest sense is the grapevine, but more generally it can refer to any plant with a growth habit of trailing or scandent stems, lianas or runners. The word also can refer to such stems or runners themselves, in the United Kingdom, the term vine applies almost exclusively to the grapevine. The term climber is used for all climbing plants, certain plants always grow as vines, while a few grow as vines only part of the time. For instance, poison ivy and bittersweet can grow as low shrubs when support is not available, a vine displays a growth form based on long stems. This has been a successful growth form for plants such as kudzu and Japanese honeysuckle. There are some tropical vines that develop skototropism, and grow away from the light, growth away from light allows the vine to reach a tree trunk, which it can then climb to brighter regions. The vine growth form may also enable plants to large areas quickly. This is the case with periwinkle and ground ivy and it is also an adaptation to life in areas where small patches of fertile soil are adjacent to exposed areas with more sunlight but little or no soil. A vine can root in the soil but have most of its leaves in the brighter, exposed area, the evolution of a climbing habit has been implicated as a key innovation associated with the evolutionary success and diversification of a number of taxonomic groups of plants. It has evolved independently in several plant families, using many different climbing methods such as and it directs its stem into a crevice in the bark of fibrous barked trees where the stem adopts a flattened profile and grows up the tree underneath the host trees outer bark. The fetterbush then sends out branches that emerge near the top of the tree and these may be divided into woody vines or lianas, such as wisteria, kiwifruit, and common ivy, and herbaceous vines, such as morning glory. One odd group of vining plants is the fern genus Lygodium, the stem does not climb, but rather the fronds do. The fronds unroll from the tip, and theoretically never stop growing, they can form thickets as they unroll over other plants, rockfaces, gardeners can use the tendency of climbing plants to grow quickly. If a plant display is wanted quickly, a climber can achieve this, climbers can be trained over walls, pergolas, fences, etc. Climbers can be grown over other plants to provide additional attraction, artificial support can also be provided. Some climbers climb by themselves, others need work, such as tying them in, vines widely differ in size, form and evolutionary origin. Darwin classified climbing groups based on their climbing method and he classified five classes of vines including twining plants, leaf climbers, tendril bearers, root climbers and hook climbers. Vines are unique in that they have multiple origins and a wide range of phenotypic plasticity

Tendril
–
They do not have a lamina or blade, but they can photosynthesize. They can be formed from modified shoots, modified leaves, or auxiliary branches and are sensitive to chemicals, often determining the direction of growth. The earliest and most comprehensive study of tendrils was Charles Darwins monograph On the Movements and Habits of Climbing Plants and this work also coined the term circumnutation to describe the motion of growing stems and tendrils seeking supports. Darwin also observed the phenomenon now known as tendril perversion, in which tendrils adopt the shape of two sections of counter-twisted helices with a transition in the middle, in the garden pea, it is only the terminal leaflets that are modified to become tendrils. In other plants such as the yellow vetch, the leaf is modified to become tendrils while the stipules become enlarged. Still others use the rachis of a leaf as a tendril. The specialised pitcher traps of Nepenthes plants form on the end of tendrils, the tendrils of aerial pitchers are usually coiled in the middle. If the tendril comes into contact with an object for long enough it will curl around it. In this way, the help to support the growing stem of the plant. Tendrils of Cuscuta, a plant, are guided by airborne chemicals. ExcitingNature. com - Tendril in Thigmotropism Media related to Tendrils at Wikimedia Commons

Peafowl
–
The peafowl include three species of birds in the genera Pavo and Afropavo of the Phasianidae family, the pheasants and their allies. There are two Asiatic species and one African species, male peafowl are known for their piercing call and their extravagant plumage. The latter is especially prominent in the Asiatic species, who have a tail or train of covert feathers which they display as part of a courtship ritual. The term peacock is properly reserved for the male, the female is known as a peahen, the functions of the elaborate iridescent coloration and large train of peacocks have been the subject of extensive scientific debate. Charles Darwin suggested they served to attract females, and the features of the males had evolved by sexual selection. The Indian peacock has iridescent blue and green plumage, the peacock tail, known as a train, consists not of tail quill feathers, but highly elongated upper tail coverts. These feathers are marked with eyespots, best seen when a peacock fans his tail, both sexes of all species have a crest atop the head. The Indian peahen has a mixture of grey, brown. The female also displays her plumage to ward off female competition or signal danger to her young, the green peafowl differs from the Indian peafowl in that the male has green and gold plumage with black wings with a sheen of blue. Unlike the Indian peafowl, the green peahen is similar to the male, only having shorter upper tail coverts, a more coppery neck, the Congo peacock male does not display his covert feathers, but uses his actual tail feathers during courtship displays. These feathers are shorter than those of the Indian and green species. Females of the Indian and African species are dull grey and/or brown, chicks of both sexes in all the species are cryptically coloured. They vary between yellow and tawny, usually with patches of brown or light tan and dirty white ivory. Occasionally, peafowl appear with white plumage and this can result in the complete lack of coloration of their plumage, while preserving normal eye colour. By contrast, true albino peafowl have a lack of melanin. Leucistic peachicks are born yellow and become white as they mature. As with many birds, vibrant iridescent plumage colours are not primarily pigments, optical interference Bragg reflections based on regular, periodic nanostructures of the barbules of the feathers produce the peacocks colours. Slight changes to the spacing of these result in different colours

Lion
–
The lion is one of the big cats in the genus Panthera and a member of the family Felidae. The commonly used term African lion collectively denotes the several subspecies in Africa, with some males exceeding 250 kg in weight, it is the second-largest living cat after the tiger. Wild lions currently exist in sub-Saharan Africa and in India, in ancient historic times, their range was in most of Africa, including North Africa, and across Eurasia from Greece and southeastern Europe to India. Lion populations are untenable outside designated reserves and national parks, although the cause of the decline is not fully understood, habitat loss and conflicts with humans are the greatest causes of concern. Within Africa, the West African lion population is particularly endangered, in the wild, males seldom live longer than 10 to 14 years, as injuries sustained from continual fighting with rival males greatly reduce their longevity. In captivity they can more than 20 years. They typically inhabit savanna and grassland, although they may take to bush, Lions are unusually social compared to other cats. A pride of lions consists of related females and offspring and a number of adult males. Groups of female lions typically hunt together, preying mostly on large ungulates, Lions are apex and keystone predators, although they are also expert scavengers obtaining over 50 percent of their food by scavenging as opportunity allows. While lions do not typically hunt humans, some have, sleeping mainly during the day, lions are active primarily at night, although sometimes at twilight. Highly distinctive, the lion is easily recognised by its mane. It has been depicted in sculptures, in paintings, on national flags. Lions have been kept in menageries since the time of the Roman Empire, Zoos are cooperating worldwide in breeding programs for the endangered Asiatic subspecies. The lions name, similar in many Romance languages, is derived from the Latin leo, the Hebrew word לָבִיא may also be related. It was one of the originally described by Linnaeus, who gave it the name Felis leo, in his eighteenth-century work. The lions closest relatives are the species of the genus Panthera, the tiger, the snow leopard, the jaguar. P. leo evolved in Africa between 1 million and 800,000 years ago, before spreading throughout the Holarctic region and it appeared in the fossil record in Europe for the first time 700,000 years ago with the subspecies Panthera leo fossilis at Isernia in Italy. From this lion derived the later cave lion, which appeared about 300,000 years ago, Lions died out in northern Eurasia at the end of the last glaciation, about 10,000 years ago, this may have been secondary to the extinction of Pleistocene megafauna

Tumulus
–
A tumulus is a mound of earth and stones raised over a grave or graves. Tumuli are also known as barrows, burial mounds or kurgans, a cairn, which is a mound of stones built for various purposes, may also originally have been a tumulus. Tumuli are often categorised according to their external apparent shape, in this respect, a long barrow is a long tumulus, usually constructed on top of several burials, such as passage graves. A round barrow is a tumulus, also commonly constructed on top of burials. The internal structure and architecture of both long and round barrows has a range, the categorization only refers to the external apparent shape. The method of inhumation may involve a dolmen, a cist, a mortuary enclosure, examples of barrows include Duggleby Howe and Maeshowe. The funeral of Patroclus is described in book 23 of the Iliad, Patroclus is burned on a pyre, and his bones are collected into a golden urn in two layers of fat. The barrow is built on the location of the pyre, achilles then sponsors funeral games, consisting of a chariot race, boxing, wrestling, running, a duel between two champions to the first blood, discus throwing, archery and spear throwing. Beowulfs body is taken to Hronesness, where it is burned on a funeral pyre, during cremation, the Geats lament the death of their lord, a widows lament being mentioned in particular, singing dirges as they circumambulate the barrow. Afterwards, a mound is built on top of a hill, overlooking the sea, a band of twelve of the best warriors ride around the barrow, singing dirges in praise of their lord. Parallels have also drawn to the account of Attilas burial in Jordanes Getica. Jordanes tells that as Attilas body was lying in state, the best horsemen of the Huns circled it, as in circus games. An Old Irish Life of Columcille reports that every funeral procession halted at a mound called Eala, whereupon the corpse was laid, archaeologists often classify tumuli according to their location, form, and date of construction. Some British types are listed below, Bank barrow Bell barrow Bowl barrow D-shaped barrow - round barrow with a flat edge at one side often defined by stone slabs. Disc barrow Fancy barrow - generic term for any Bronze Age barrows more elaborate than a hemispherical shape. Long barrow Oval barrow - a Neolithic long barrow consisting of an elliptical, platform barrow - The least common of the recognised types of round barrow, consisting of a flat, wide circular mound that may be surrounded by a ditch. They occur widely across southern England with a concentration in East and West Sussex. Pond barrow - a barrow consisting of a circular depression, surrounded by a bank running around the rim of the depression

Alazani
–
The Alazani is a river that flows through the Caucasus. It is the tributary of the Kura in eastern Georgia. Part of its path forms the border between Georgia and Azerbaijan, before it meets the Kura at the Mingəçevir Reservoir, the Alazani originates in the Greater Caucasus, south of the main ridge, in the northwestern part of the Akhmeta District. It flows initially to the south towards the town Akhmeta, then through the fruitful Alazani Valley of Kakheti towards the southeast, the Alazani is the center of the Georgian wine industry. For centuries, it was a gateway for Persian invaders. The Alazani dries up during the winter, but in the spring, snow melt from the mountains swells the river enormously. The river is used for irrigation and for drinking water. In the 1990s, Chinese investors built many small power plants. The river is popular with tourists for rafting trips. A light pollution of the river with biological substances comes from untreated sewage from the cities and other communities, in the districts of Kvareli and Lagodekhi, water quality is said to be quite bad. Alazani serves also as the name of different Georgian wines, among them the semi-dry brands of Marani Alazani Valley, the information in this article is a based on and/or translated from that in its German equivalent

Gelati Monastery
–
Gelati is a medieval monastic complex near Kutaisi, in the Imereti region of western Georgia. A masterpiece of the Georgian Golden Age, Gelati was founded in 1106 by King David IV of Georgia and is recognized by UNESCO as a World Heritage Site, historically, Gelati was one of the main cultural and intellectual centers in Georgia. Among the religious authors were celebrated scholars as Ioane Petritsi and Arsen Ikaltoeli, due to the extensive work carried out by the Gelati Academy, people of the time called it a new Hellas and a second Athos. The Gelati Monastery has preserved a number of murals and manuscripts dating back to the 12th to 17th centuries. The Khakhuli triptych was enshrined at Gelati until being stolen in 1859, Gelati is the burial site of its founder and one of the greatest Georgian kings David IV. Near King Davids grave are the gates of Ganja, which were taken as a trophy by King Demetrius I of Georgia in 1138

Deer
–
Deer are the ruminant mammals forming the family Cervidae. The two main groups are the Cervinae, including the muntjac, the deer and the chital, and the Capreolinae, including the elk, reindeer, the Western roe deer. Female reindeer, and male deer of all species, grow, in this they differ from permanently horned antelope, which are in the same order, Artiodactyla. The musk deer of Asia and water chevrotain of tropical African and Asian forests are not usually regarded as true deer and form their own families, Moschidae and Tragulidae, respectively. Deer appear in art from Palaeolithic cave paintings onwards, and they have played a role in mythology, religion and their economic importance includes the use of their meat as venison, their skins as soft, strong buckskin, and their antlers as handles for knives. Deer hunting has been a sport since at least the Middle Ages. Deer live in a variety of biomes, ranging from tundra to the tropical rainforest, while often associated with forests, many deer are ecotone species that live in transitional areas between forests and thickets and prairie and savanna. The majority of deer species inhabit temperate mixed deciduous forest, mountain mixed coniferous forest, tropical seasonal/dry forest. Clearing open areas within forests to some extent may actually benefit deer populations by exposing the understory and allowing the types of grasses, weeds, additionally, access to adjacent croplands may also benefit deer. However, adequate forest or brush cover must still be provided for populations to grow, however, fallow deer have been introduced to South Africa. There are also species of deer that are highly specialized, and live almost exclusively in mountains, grasslands, swamps. Some deer have a distribution in both North America and Eurasia. Examples include the caribou that live in Arctic tundra and taiga and moose that inhabit taiga, huemul deer of South Americas Andes fill the ecological niches of the ibex and wild goat, with the fawns behaving more like goat kids. Mountain slope habitats vary from moist coniferous/mixed forested habitats to dry forests with alpine meadows higher up. The foothills and river valleys between the mountain provide a mosaic of cropland and deciduous parklands. The rare woodland caribou have the most restricted range living at altitudes in the subalpine meadows. Elk and mule deer both migrate between the alpine meadows and lower coniferous forests and tend to be most common in this region, elk also inhabit river valley bottomlands, which they share with White-tailed deer. They also live in the aspen parklands north of Calgary and Edmonton, the adjacent Great Plains grassland habitats are left to herds of elk, American bison, and pronghorn antelope

Niko Pirosmani
–
Niko Pirosmani, simply referred to as Nikala, was a Georgian primitivist painter who posthumously rose to prominence. Pirosmani was born in the Georgian village of Mirzaani to a peasant family in Kakheti province and his parents, Aslan Pirosmanashvili and Tekle Toklikishvili, were farmers, who owned a small vineyard, with a few cows and oxen. He was later orphaned and left in the care of his two sisters, Mariam and Pepe. He moved with them to Tbilisi in 1870, in 1872, while living in a little apartment not far from Tbilisi railway station, he worked as a servant to wealthy families and learned to read and write Russian and Georgian. In 1876, he returned to Mirzaani and worked as a herdsman, Pirosmani gradually taught himself to paint. One of his specialties was painting directly into black oilcloth, in 1882, with self-taught George Zaziashvili, he opened a painting workshop, where they made signboards. In 1890, he worked as a railroad conductor, in 1893, he co-founded a dairy farm in Tbilisi, which he left in 1901. Throughout his life, Pirosmani, who was poor, was willing to take ordinary jobs including housepainting and whitewashing buildings and he also worked for shopkeepers in Tbilisi, creating signboards, paintings, and portraits, according to their orders. Although his paintings had some local popularity his relationship with professional artists remained uneasy, in April 1918, he died of malnutrition and liver failure. He was buried at the Nino cemetery, the location was not registered and is unknown. Pirosmani’s paintings were influenced by the conditions of his time. There are many works about merchants, shopkeepers, workmen, Pirosmani was fond of nature and rural life. He was the only Georgian animalist, Pirosmani also was attracted by historical figures and themes such as Shota Rustaveli, Queen Tamar, Giorgi Saakadze, as well as ordinary Georgian people and their everyday lives. Unlike other artists, Niko didn’t aim at a pure imitation of the nature, some of his paintings are monochrome. His paintings demonstrate the authors sharp compositional consideration, placements of the figures are frontal, while faces do not demonstrate a specific mood. In the 1910s, he won the enthusiasm of the Russian poet Mikhail Le-Dantyu, Ilia Zhdanevich wrote a letter about Pirosmani to the newspaper Zakavkazskaia Rech, which it published on February 13,1913. He undertook to publicise Pirosmanis painting in Moscow, critics writing later in the same newspaper were impressed with his talent. In the same year, an article about Niko Pirosmani and his art was published in Georgian newspaper Temi

Brass
–
Brass is a metal alloy made of copper and zinc, the proportions of zinc and copper can be varied to create a range of brasses with varying properties. It is an alloy, atoms of the two constituents may replace each other within the same crystal structure. By comparison, bronze is principally an alloy of copper and tin, however, bronze and brass may also include small proportions of a range of other elements including arsenic, phosphorus, aluminium, manganese, and silicon. The term is applied to a variety of brasses. Modern practice in museums and archaeology increasingly avoids both terms for objects in favour of the all-embracing copper alloy. It is also used in zippers, Brass is often used in situations in which it is important that sparks not be struck, such as in fittings and tools used near flammable or explosive materials. Brass has higher malleability than bronze or zinc, the relatively low melting point of brass and its flow characteristics make it a relatively easy material to cast. By varying the proportions of copper and zinc, the properties of the brass can be changed, allowing hard, the density of brass is 8.4 to 8.73 grams per cubic centimetre. Today, almost 90% of all alloys are recycled. Because brass is not ferromagnetic, it can be separated from ferrous scrap by passing the scrap near a powerful magnet, Brass scrap is collected and transported to the foundry where it is melted and recast into billets. Billets are heated and extruded into the form and size. The general softness of brass means that it can often be machined without the use of cutting fluid, aluminium makes brass stronger and more corrosion-resistant. Aluminium also causes a highly beneficial hard layer of oxide to be formed on the surface that is thin, transparent. Tin has an effect and finds its use especially in seawater applications. Combinations of iron, aluminium, silicon and manganese make brass wear and tear resistant, to enhance the machinability of brass, lead is often added in concentrations of around 2%. Since lead has a melting point than the other constituents of the brass. The pattern the globules form on the surface of the brass increases the available surface area which in turn affects the degree of leaching. In addition, cutting operations can smear the lead globules over the surface and these effects can lead to significant lead leaching from brasses of comparatively low lead content

Steel
–
Steel is an alloy of iron and other elements, primarily carbon, that is widely used in construction and other applications because of its high tensile strength and low cost. Steels base metal is iron, which is able to take on two forms, body centered cubic and face centered cubic, depending on its temperature. It is the interaction of those allotropes with the elements, primarily carbon. In the body-centred cubic arrangement, there is an atom in the centre of each cube. Carbon, other elements, and inclusions within iron act as hardening agents that prevent the movement of dislocations that otherwise occur in the lattices of iron atoms. The carbon in steel alloys may contribute up to 2. 1% of its weight. Steels strength compared to pure iron is possible at the expense of irons ductility. With the invention of the Bessemer process in the mid-19th century and this was followed by Siemens-Martin process and then Gilchrist-Thomas process that refined the quality of steel. With their introductions, mild steel replaced wrought iron, further refinements in the process, such as basic oxygen steelmaking, largely replaced earlier methods by further lowering the cost of production and increasing the quality of the product. Today, steel is one of the most common materials in the world and it is a major component in buildings, infrastructure, tools, ships, automobiles, machines, appliances, and weapons. Modern steel is generally identified by various grades defined by assorted standards organizations, the noun steel originates from the Proto-Germanic adjective stakhlijan, which is related to stakhla. The carbon content of steel is between 0. 002% and 2. 1% by weight for plain iron–carbon alloys and these values vary depending on alloying elements such as manganese, chromium, nickel, iron, tungsten, carbon and so on. Basically, steel is an alloy that does not undergo eutectic reaction. In contrast, cast iron does undergo eutectic reaction, too little carbon content leaves iron quite soft, ductile, and weak. Carbon contents higher than those of steel make an alloy, commonly called pig iron, while iron alloyed with carbon is called carbon steel, alloy steel is steel to which other alloying elements have been intentionally added to modify the characteristics of steel. Common alloying elements include, manganese, nickel, chromium, molybdenum, boron, titanium, vanadium, tungsten, cobalt, and niobium. Additional elements are important in steel, phosphorus, sulfur, silicon, and traces of oxygen, nitrogen, and copper. Alloys with a higher than 2. 1% carbon content, depending on other element content, cast iron is not malleable even when hot, but it can be formed by casting as it has a lower melting point than steel and good castability properties

Griffin
–
The griffin, griffon, or gryphon is a legendary creature with the body, tail, and back legs of a lion, the head and wings of an eagle, and an eagles talons as its front feet. Because the lion was considered the king of the beasts and the eagle the king of birds. The griffin was thought of as king of all creatures. Griffins are known for guarding treasure and priceless possessions, in Greek and Roman texts, griffins and Arimaspeans were associated with gold. Indeed, in later accounts, griffins were said to lay eggs in burrows on the grounds, in antiquity it was a symbol of divine power and a guardian of the divine. The derivation of this remains uncertain. It could be related to the Greek word γρυπός, meaning curved, also, this could have been an Anatolian loan word, compare Akkadian karūbu, and similar to Cherub. A related Hebrew word is כרוב, Most statuary representations of griffins depict them with bird-like talons, although in some older illustrations griffins have a lions forelimbs, they generally have a lions hindquarters. Its eagles head is given prominent ears, these are sometimes described as the lions ears, but are often elongated. Infrequently, a griffin is portrayed without wings, or a wingless eagle-headed lion is identified as a griffin, in 15th-century and later heraldry, such a beast may be called an alce or a keythong. In heraldry, a griffin always has forelegs like an eagles hind-legs, there is evidence of representations of griffins in Ancient Iranian and Ancient Egyptian art dating back to before 3000 BC. In Egypt, a griffin can be seen in a cosmetic palette from Hierakonpolis, known as the Two Dog Palette, which is dated to ca. In Iran, griffins appeared on seals from Susa as early as 3000 BC. Griffin depictions appear in the Levant, Syria. Early depictions of griffins in Ancient Greek art are found in the 15th century BC frescoes in the Throne Room of the Bronze Age Palace of Knossos and it continued being a favored decorative theme in Archaic and Classical Greek art. In Central Asia, the griffin appears about a years after Bronze Age Crete, in the 5th–4th centuries BC. The Achaemenids considered the griffin a protector from evil, witchcraft, the modern generalist calls it the lion-griffin, as for example, Robin Lane Fox, in Alexander the Great,1973,31 and notes p. The Pisa Griffin is a bronze sculpture that has been in Pisa in Italy since the Middle Ages. It is the largest bronze medieval Islamic sculpture known, at three feet tall, and was probably created in the 11th century in Al-Andaluz

Samtavisi Cathedral
–
Samtavisi is an eleventh-century Georgian Orthodox cathedral in eastern Georgia, in the region of Shida Kartli, some 45km from the nation’s capital Tbilisi. The cathedral is now one of the centers of the Eparchy of Samtavisi, the cathedral is located on the left bank of the Lekhura River, some 11km of the town of Kaspi. According to a Georgian tradition, the first monastery on this place was founded by the Assyrian missionary Isidore in 572, neither of these buildings has survived however. The earliest extant structures date to the century, the main edifice being built in 1030 as revealed by a now lost stone inscription. The cathedral was built by a bishop and a skilful architect Hilarion who also authored the nearby church of Ashuriani. Heavily damaged by a series of earthquakes, the Cathedral was partially reconstructed in the 15th and 19th centuries, the masterly decorated eastern façade is the only survived original structure. The Samtavisi Cathedral is a rectangular 4-piered cruciform domed church and it illustrates a Georgian interpretation of the cross-in-square form which set an example for many churches built in the heyday of medieval Georgia. The exterior is distinguished by the use of ornamental blind arcading. The apses do not project, but their position is marked by deep recesses in the wall. In contrast to earlier Georgian churches, the drum of the dome is surmounted by a conical roof. Artistically, the most rounded portion of the church is its five-arched eastern façade, all these structures date to the 17th-18th centuries.

Cupronickel
–
Cupronickel is an alloy of copper that contains nickel and strengthening elements, such as iron and manganese. Despite its high content, cupronickel is silver in colour. Cupronickel is highly resistant to corrosion in seawater because its potential is adjusted to be neutral with regard to seawater. Another common use of cupronickel is in silver-coloured modern-circulated coins, a typical mix is 75% copper, 25% nickel, and a trace amount of manganese. In the past, true silver coins were debased with cupronickel, Cupronickel alloys are used for marine applications due to their resistance to seawater corrosion, good fabricability, and their effectiveness in lowering macrofouling levels. Alloys ranging in composition from 90% Cu–10% Ni to 70% Cu–30% Ni are commonly specified in heat exchanger or condenser tubes in a variety of marine applications. Desalination plants, Cupronickel alloys are used in brine heaters, heat rejection and recovery, offshore oil and gas platforms and processing and FPSO vessels, Cupronickel alloys are used in systems and splash zone sheathings. Power generation, Cupronickel alloys are used in steam turbine condensers, oil coolers, auxiliary cooling systems and high pressure pre-heaters at nuclear, seawater system design, Cupronickel alloys are used in tubular heat exchangers and condensers, piping and high pressure systems. Seawater system components, Cupronickel alloys are used in condenser and heat exchanger tubes, tubesheets, piping, fittings, pumps, in Europe, Switzerland pioneered the nickel billon coinage in 1850, with the addition of silver. In 1968, Switzerland adopted the far cheaper 75,25 copper to nickel ratio then being used by the Belgians, the United States, and Germany. From 1947 to 2012, all “silver” coinage in the UK was made from cupronickel, prior to these dates, both denominations had been made only in silver in the United States. Cupronickel is the cladding on either side of United States half-dollars since 1971, currently, some circulating coins, such as the United States Jefferson nickel, the Swiss franc, and the South Korean 500 and 100 won are made of solid cupronickel. Single-core thermocouple cables use a single pair of thermocouple conductors such as iron-constantan. These have the element of constantan or nickel-chromium alloy within a sheath of copper. Cupronickel is used in cryogenic applications, beginning around the turn of the 20th century, bullet jackets were commonly made from this material. It was soon replaced with gilding metal to reduce fouling in the bore. Currently, cupronickel remains the basic material for silver-plated cutlery and it is commonly used for mechanical and electrical equipment, medical equipment, zippers, jewelry items, and as material for strings for string instruments. Fender Musical Instruments used CuNiFe magnets in their Wide Range Humbucker pickup for various Telecaster and Starcaster guitars during the 1970s, for high-quality cylinder locks and locking systems, cylinder cores are made from wear-resistant cupronickel

Coat of arms of Georgia (country)
–
The coat of arms of Georgia is one of the national symbols of the republic. It is partially based on the arms of the Georgian royal house and features Saint George. In addition to St. Gules, with an image of Saint George, riding a horse trampling upon a dragon, whose head is pierced by the saints spear. It has two lions rampant as supporters of the shield, which is surmounted with the crown of Georgia. The motto below the shield reads as Strength is in Unity, 1918-1921 and 1991-2004, This coat of arms was in use by the Democratic Republic of Georgia throughout its existence in 1918-1921. However, a decision was made in favor of Saint George. Restored in 1991, this coat of arms was replaced by the current one in 2004. 1801-1917, Before 1917, when Georgia was part of the Russian Empire, the Georgian coat of arms appeared on the Greater Coat of Arms of the Russian Empire, as part of the coat of arms of Caucasus. Before 1801, Coats of arms were mostly those of the Bagrationi, who claimed to have King David among their ancestors, Coat of arms of the Bagrationi dynasty Pogoń Ruska coat of arms President of Georgia website The Georgian Coat of Arms in, Georgian History by Giorgi Gabeskiria

Copper
–
Copper is a chemical element with symbol Cu and atomic number 29. It is a soft, malleable, and ductile metal with high thermal and electrical conductivity. A freshly exposed surface of copper has a reddish-orange color. Copper is one of the few metals that occur in nature in directly usable metallic form as opposed to needing extraction from an ore and this led to very early human use, from c.8000 BC. Copper used in buildings, usually for roofing, oxidizes to form a green verdigris, Copper is sometimes used in decorative art, both in its elemental metal form and in compounds as pigments. Copper compounds are used as agents, fungicides, and wood preservatives. Copper is essential to all living organisms as a trace dietary mineral because it is a key constituent of the enzyme complex cytochrome c oxidase. In molluscs and crustaceans, copper is a constituent of the blood pigment hemocyanin, replaced by the hemoglobin in fish. In humans, copper is found mainly in the liver, muscle, the adult body contains between 1.4 and 2.1 mg of copper per kilogram of body weight. The filled d-shells in these elements contribute little to interatomic interactions, unlike metals with incomplete d-shells, metallic bonds in copper are lacking a covalent character and are relatively weak. This observation explains the low hardness and high ductility of single crystals of copper, at the macroscopic scale, introduction of extended defects to the crystal lattice, such as grain boundaries, hinders flow of the material under applied stress, thereby increasing its hardness. For this reason, copper is supplied in a fine-grained polycrystalline form. The softness of copper partly explains its high conductivity and high thermal conductivity. The maximum permissible current density of copper in open air is approximately 3. 1×106 A/m2 of cross-sectional area, Copper is one of a few metallic elements with a natural color other than gray or silver. Pure copper is orange-red and acquires a reddish tarnish when exposed to air, as with other metals, if copper is put in contact with another metal, galvanic corrosion will occur. A green layer of verdigris can often be seen on old structures, such as the roofing of many older buildings. Copper tarnishes when exposed to sulfur compounds, with which it reacts to form various copper sulfides. There are 29 isotopes of copper, 63Cu and 65Cu are stable, with 63Cu comprising approximately 69% of naturally occurring copper, both have a spin of 3⁄2

Aluminium
–
Aluminium or aluminum is a chemical element in the boron group with symbol Al and atomic number 13. It is a silvery-white, soft, nonmagnetic, ductile metal, Aluminium metal is so chemically reactive that native specimens are rare and limited to extreme reducing environments. Instead, it is combined in over 270 different minerals. The chief ore of aluminium is bauxite, Aluminium is remarkable for the metals low density and its ability to resist corrosion through the phenomenon of passivation. Aluminium and its alloys are vital to the industry and important in transportation and structures, such as building facades. The oxides and sulfates are the most useful compounds of aluminium, despite its prevalence in the environment, no known form of life uses aluminium salts metabolically, but aluminium is well tolerated by plants and animals. Because of these salts abundance, the potential for a role for them is of continuing interest. Aluminium is a soft, durable, lightweight, ductile. It is nonmagnetic and does not easily ignite, a fresh film of aluminium serves as a good reflector of visible light and an excellent reflector of medium and far infrared radiation. The yield strength of aluminium is 7–11 MPa, while aluminium alloys have yield strengths ranging from 200 MPa to 600 MPa. Aluminium has about one-third the density and stiffness of steel and it is easily machined, cast, drawn and extruded. Aluminium atoms are arranged in a cubic structure. Aluminium has an energy of approximately 200 mJ/m2. Aluminium is a thermal and electrical conductor, having 59% the conductivity of copper. Aluminium is capable of superconductivity, with a critical temperature of 1.2 kelvin. Aluminium is the most common material for the fabrication of superconducting qubits, the strongest aluminium alloys are less corrosion resistant due to galvanic reactions with alloyed copper. This corrosion resistance is reduced by aqueous salts, particularly in the presence of dissimilar metals. In highly acidic solutions, aluminium reacts with water to form hydrogen, primarily because it is corroded by dissolved chlorides, such as common sodium chloride, household plumbing is never made from aluminium

Nickel
–
Nickel is a chemical element with symbol Ni and atomic number 28. It is a silvery-white lustrous metal with a golden tinge. Nickel belongs to the metals and is hard and ductile. Meteoric nickel is found in combination with iron, a reflection of the origin of elements as major end products of supernova nucleosynthesis. An iron–nickel mixture is thought to compose Earths inner core, use of nickel has been traced as far back as 3500 BCE. Nickel was first isolated and classified as an element in 1751 by Axel Fredrik Cronstedt. The elements name comes from a mischievous sprite of German miner mythology, Nickel, an economically important source of nickel is the iron ore limonite, which often contains 1–2% nickel. Nickels other important ore minerals include garnierite, and pentlandite, major production sites include the Sudbury region in Canada, New Caledonia in the Pacific, and Norilsk in Russia. Nickel is slowly oxidized by air at room temperature and is considered corrosion-resistant, historically, it has been used for plating iron and brass, coating chemistry equipment, and manufacturing certain alloys that retain a high silvery polish, such as German silver. About 6% of world production is still used for corrosion-resistant pure-nickel plating. Nickel-plated objects sometimes provoke nickel allergy, Nickel has been widely used in coins, though its rising price has led to some replacement with cheaper metals in recent years. Nickel is one of four elements that are ferromagnetic around room temperature, alnico permanent magnets based partly on nickel are of intermediate strength between iron-based permanent magnets and rare-earth magnets. The metal is valuable in modern times chiefly in alloys, about 60% of world production is used in nickel-steels, other common alloys and some new superalloys comprise most of the remainder of world nickel use, with chemical uses for nickel compounds consuming less than 3% of production. As a compound, nickel has a number of chemical manufacturing uses. Nickel is a nutrient for some microorganisms and plants that have enzymes with nickel as an active site. Nickel is a metal with a slight golden tinge that takes a high polish. It is one of four elements that are magnetic at or near room temperature. Its Curie temperature is 355 °C, meaning that bulk nickel is non-magnetic above this temperature, the unit cell of nickel is a face-centered cube with the lattice parameter of 0.352 nm, giving an atomic radius of 0.124 nm

Tbilisi
–
Tbilisi, commonly known by its former name Tiflis, is the capital and the largest city of Georgia, lying on the banks of the Kura River with a population of roughly 1.5 million inhabitants. Founded in the 5th century by the monarch of Georgias ancient precursor the Kingdom of Iberia, Tbilisi has since served, with intermissions, as the capital of various Georgian kingdoms and republics. Under Russian rule, from 1801 to 1917 Tiflis was the seat of the Imperial Viceroy governing both sides of the entire Caucasus. Tbilisis varied history is reflected in its architecture, which is a mix of medieval, classical, Middle Eastern, Art Nouveau, historically, Tbilisi has been home to people of diverse cultural, ethnic, and religious backgrounds, though it is overwhelmingly Eastern Orthodox Christian. Archaeological studies of the region have indicated human settlement in the territory of Tbilisi as early as the 4th millennium BC, according to an old legend, the present-day territory of Tbilisi was covered by forests as late as 458. One widely accepted variant of the legend of Tbilisis founding states that King Vakhtang I Gorgasali of Georgia went hunting in the wooded region with a falcon. The Kings falcon allegedly caught or injured a pheasant during the hunt, King Vakhtang became so impressed with the hot springs that he decided to cut down the forest and build a city on the location. The name Tbilisi derives from Old Georgian Tbilisi, and further from Tpili, the name Tbili or Tbilisi was therefore given to the city because of the areas numerous sulphuric hot springs that came out of the ground. King Dachi I Ujarmeli, who was the successor of Vakhtang I Gorgasali, Tbilisi was not the capital of a unified Georgian state at that time and did not include the territory of Colchis. It was, however, the city of Eastern Georgia/Iberia. During his reign, King Dachi I oversaw the construction of the wall that lined the citys new boundaries. From the 6th century, Tbilisi grew at a steady pace due to the favourable and strategic location which placed the city along important trade. Tbilisis favourable and strategic location did not necessarily bode well for its existence as Eastern Georgias/Iberias capital, in the year 627, Tbilisi was sacked by the Byzantine/Khazar armies and later, in 736–738, Arab armies entered the town under Marwan II Ibn-Muhammad. After this point, the Arabs established an emirate centered in Tbilisi, in 764, Tbilisi, still under Arab control was once again sacked by the Khazars. In 853, the armies of Arab leader Bugha Al-Turki invaded Tbilisi in order to enforce its return to Abbasid allegiance, the Arab domination of Tbilisi continued until about 1050. In 1068, the city was again sacked, only this time by the Seljuk Turks under Sultan Alp Arslan. In 1122, after fighting with the Seljuks that involved at least 60,000 Georgians and up to 300,000 Turks. After the battles for Tbilisi concluded, David moved his residence from Kutaisi to Tbilisi, making it the capital of a unified Georgian State, from 12–13th centuries, Tbilisi became a dominant regional power with a thriving economy and a well-established social system/structure

Zacharia Paliashvili
–
Zacharia Petres dze Paliashvili, also known as Zachary Petrovich Paliashvili, was a Georgian composer. Regarded as one of the founders of the Georgian classical music, his work is known for its fusion of folk songs. He was the founder of the Georgian Philharmonic Society and later, the Georgian National Opera and Ballet Theater of Tbilisi was named in his honor in 1937. Notably, Paliashvilis music serves as the basis of the National Anthem of Georgia, although Paliashvili has composed works for symphony orchestra, he is probably best known for his vocal music, which includes operas Abesalom da Eteri, Daisi, and Latavra. Paliashvili was born on 16 August 1871 in Kutaisi in the family of Petre Ivanes dze Paliashvili, an elder at the Kutaisi Georgian Catholic Church, Zacharias mother was Maria Pavles asuli Mesarkishvili. Zacharia was the child in a family of eighteen children. Although Zacharias parents were not professional musicians, their children remembered their mothers singing, in his autobiographical notes Zacharia Paliashvili writes. in our big family, my brothers and sisters displayed a natural gift of music even in their early age. To my mind the explanation of this should be sought in the fact that we, being catholics attended the church where the sounds of organ music are not only enjoyable. We spend much time in the church and gradually developed a good ear, the first to display considerable musical abilities was the eldest son Ivane Paliashvili who subsequently became an outstanding conductor. When Vano was eleven years old he was assistant to the church organist. With the help of the dean, Father I, antonishvili, little Zacharia studied Lullaby for Jesus and sang it with great success on Christmas night. The Kutaisi period, however, left an impression on the life of the future composer. It was the place of his first contact with music, subsequently, Paliashvili recalled Kutaisi many times, permeated, he said, with a truly Georgian spirit. Upon leaving the parish school, brothers Ivan and Zacharia began to play the piano under tutorship of Felix Mizandari. Mizandari did not charge the family for the lessons for he was aware that Paliashvili family was of very modest means, shortly afterwards, people in the town learned of the two talented and exceptionally persevering young musicians. The news reached father Alfonso Khitarishvili, dean of Tbilisi Georgian Catholic Church of the assumption, with the parents consent Khitarishvili took Ivan and Zacharia Paliashvili to Tbilisi. This was in the spring of 1887, the elder brother was appointed to the post of the organist and Zacharia was made his brothers assistant and a choirboy. A short time after, the family of Petre Paliashvili moved to Tbilisi

Ivane Javakhishvili
–
Prince Ivane Javakhishvili was a Georgian historian and a linguist whose voluminous works heavily influenced the modern scholarship of the history and culture of Georgia. He was also one of the fathers of the Tbilisi State University. Prince Ivane Javakhishvili was born in Tbilisi, Georgia to the family of Prince Alexander Javakhishvili. Having graduated from the Faculty of Oriental Studies of the St. Petersburg University in 1899, from 1901 to 1902, he was a visiting scholar at the University of Berlin. In 1902, he accompanied his mentor, Academician Nicholas Marr, the Tbilisi University, of which Javakhishvili became a professor and the head of the Department of the History of Georgia, rapidly assumed a dominant position in Georgias educational life. Although he was permitted to publish and teach, this probably saved his life. He was forced to step down at TSU in 1938, but was appointed director of the Department of History at the State Museum of Georgia which he headed until his death in Tbilisi in 1940. He was interred at the yard of the TSU, Javakhishvili authored more than 170 works dealing with various aspects of Georgias political, cultural, social and economic history. Since the publication of its first edition in 1908, his work, A History of the Georgian Nation, has remained one of the most comprehensive. Regrettably, it has not been translated into any other language, several of Javakhishvilis most influential articles and books including A History of the Georgian Nation have been reprinted in his twelve-volume collected works from 1977 and 1998.

Ivane Javakhishvili Tbilisi State University, is a university established on 8 February 1918 in Tbilisi, Georgia. Excluding academies and theological seminaries which have functioned in Georgia for centuries, TSU is the oldest university in Georgia. Over 18,000 students are enrolled and the number of faculty. The university has five branches in the regions of Georgia, six faculties,60 scientific-research laboratories and centers, the main founder of the university was a Georgian historian and academician, Ivane Javakhishvili. Professor Petre Melikishvili, a Georgian chemist, was chosen the first rector of TSU, the Rector of TSU since September 2016 Giorgi Sharvashidze. Tbilisi State University was founded in 1918 owing to the leadership of Georgian historian Ivane Javakhishvili and it was the first and the only educational body of this type in Caucasus Region by that time. The university is housed in the building of Georgian Nobility Gymnasium constructed by the architect Simon Kldiashvili from 1899 to 1906. The foundation of the Academy of Science of Georgia and other educational institutions was encouraged by the university. The university was opened on 26 January 1918, the day of remembrance of the Georgian King David the Builder, a church in the University garden, named after the King, has been functioning since 5 September 1995. In 1989 the university was named after its founder - Ivane Javakhishvili, Petre Melikishvili, a chemist and professor, was elected as the first rector of the university. At its commencement, the university had one faculty - that of philosophy, Ivane Javakhishvili, a Georgian historian, delivered the first lecture. At the beginning of 1918 the board of professors and lecturers numbered 18, over 35 thousand students are studying at the University and its eight regional branches. 95 educational programs were used at the course,194 at masters studies. Schools that came into being at Tbilisi University were, Mathematics, Physics, national scholarly schools of Georgian historiography, History of literature, Georgian philosophy, Study of Art, Georgian and Caucasian Linguistics, Oriental and Classic Philology. The chairs and scientific research departments serve for preparation of postgraduate students,26 qualification councils operate for conferring scientific degrees in almost all fields of science. Medical education was restored at the university in 1994, originally the specialty of medicine was opened at the faculty of biology and medicine, and the faculty of medicine became an independent unit in 2000. A center for the Management of Health Care and the Department for Continuous Medical Education were opened, the university diagnostic center provides the health care of the professors and lecturers and collaborators of the University. A printing press was set up in 1923 and a publishing-house in 1933, the University Archive was founded in 1933

Davit Kakabadze was a Georgian avant-garde painter, graphic artist and scenic designer. A multi-talent, he was also an art scholar and innovator in the field of cinematography as well as an amateur photographer, Kakabadzes works are notable for combining innovative interpretation of European Leftist art with Georgian national traditions, on which he was an expert. Kakabadze was born into a peasant family in the village of Kukhi near the town of Khoni. Sponsored by local philanthropists, he studied sciences at St. Petersburg University from which he graduated in 1916. At the same time, he attended painting classes at the studio of Dmitroyev-Kavkazsky, after a brief period of working as a painter and educator in Tbilisi, he went to Paris where he lived from 1919 to 1927. He partook in the Société des Artistes Indépendants exhibitions and joint exhibitions with the Georgian artists Lado Gudiashvili, the cycle of landscapes reproducing the nature of Kakabadzes native province of Imereti is some of the most interesting of his early works. He soon went over to an even more Leftist position, by the mid- 1920s he had rejected his cubist-influenced style in favor of more abstract sculpture and painting. Having return to Georgia in 1927, Kakabadze continued his Imereti themes in new monumental decorative landscapes, around the same time, he collaborated with the leading Georgian theatre director Kote Marjanishvili to produce several set designs for Marjanishvilis theatre in Kutaisi. In 1931, he produced a documental film The Old Monuments of Georgia. Kakabadze became a professor at the Tbilisi State Academy of Arts in 1928, eventually, he was dismissed from the Academy in 1948.
