Nuclear transmutation is the conversion of one chemical element or an isotope into another chemical element. Nuclear transmutation occurs in any process where the number of protons or neutrons in the nucleus of an atom is changed.

A transmutation can be achieved either by nuclear reactions (in which an outside particle reacts with a nucleus) or by radioactive decay, where no outside cause is needed.

Natural transmutation by stellar nucleosynthesis in the past created most of the heavier chemical elements in the known existing universe, and continues to take place to this day, creating the vast majority of the most common elements in the universe, including helium, oxygen and carbon. Most stars carry out transmutation through fusion reactions involving hydrogen and helium, while much larger stars are also capable of fusing heavier elements up to iron late in their evolution.

Elements heavier than iron, such as gold or lead, are created through elemental transmutations that can naturally occur in supernovae. One goal of alchemy, the transmutation of base substances into gold, is now known to be impossible by chemical means but possible by physical means. As stars begin to fuse heavier elements, substantially less energy is released from each fusion reaction. This continues until it reaches iron which is produced by an endothermic reaction consuming energy. No heavier element can be produced in such conditions.

One type of natural transmutation observable in the present occurs when certain radioactive elements present in nature spontaneously decay by a process that causes transmutation, such as alpha or beta decay. An example is the natural decay of potassium-40 to argon-40, which forms most of the argon in the air. Also on Earth, natural transmutations from the different mechanisms of natural nuclear reactions occur, due to cosmic ray bombardment of elements (for example, to form carbon-14), and also occasionally from natural neutron bombardment (for example, see natural nuclear fission reactor).

Artificial transmutation may occur in machinery that has enough energy to cause changes in the nuclear structure of the elements. Such machines include particle accelerators and tokamak reactors. Conventional fission power reactors also cause artificial transmutation, not from the power of the machine, but by exposing elements to neutrons produced by fission from an artificially produced nuclear chain reaction. For instance, when a uranium atom is bombarded with slow neutrons, fission takes place. This releases, on average, three neutrons and a large amount of energy. The released neutrons then cause fission of other uranium atoms, until all of the available uranium is exhausted. This is called a chain reaction.

Artificial nuclear transmutation has been considered as a possible mechanism for reducing the volume and hazard of radioactive waste.

History

Alchemy
The term transmutation dates back to alchemy. Alchemists pursued the philosopher's stone, capable of chrysopoeia – the transformation of base metals into gold. While alchemists often understood chrysopoeia as a metaphor for a mystical, or religious process, some practitioners adopted a literal interpretation, and tried to make gold through physical experiment. The impossibility of the metallic transmutation had been debated amongst alchemists, philosophers and scientists since the Middle Ages. Pseudo-alchemical transmutation was outlawed and publicly mocked beginning in the fourteenth century. Alchemists like Michael Maier and Heinrich Khunrath wrote tracts exposing fraudulent claims of gold making. By the 1720s, there were no longer any respectable figures pursuing the physical transmutation of substances into gold. Antoine Lavoisier, in the 18th century, replaced the alchemical theory of elements with the modern theory of chemical elements, and John Dalton further developed the notion of atoms (from the alchemical theory of corpuscles) to explain various chemical processes. The disintegration of atoms is a distinct process involving much greater energies than could be achieved by alchemists.

Modern physics
It was first consciously applied to modern physics by Frederick Soddy when he, along with Ernest Rutherford in 1901, discovered that radioactive thorium was converting itself into radium. At the moment of realization, Soddy later recalled, he shouted out: "Rutherford, this is transmutation!" Rutherford snapped back, "For Christ's sake, Soddy, don't call it transmutation. They'll have our heads off as alchemists."

Rutherford and Soddy were observing natural transmutation as a part of radioactive decay of the alpha decay type. The first artificial transmutation was accomplished in 1925 by Patrick Blackett, a research fellow working under Rutherford, with the transmutation of nitrogen into oxygen, using alpha particles directed at nitrogen 14N + α → 17O + p. Rutherford had shown in 1919 that a proton (he called it a hydrogen atom) was emitted from alpha bombardment experiments but he had no information about the residual nucleus. Blackett's 1921–1924 experiments provided the first experimental evidence of an artificial nuclear transmutation reaction. Blackett correctly identified the underlying integration process and the identity of the residual nucleus. In 1932, a fully artificial nuclear reaction and nuclear transmutation was achieved by Rutherford's colleagues John Cockcroft and Ernest Walton, who used artificially accelerated protons against lithium-7 to split the nucleus into two alpha particles. The feat was popularly known as "splitting the atom," although it was not the modern nuclear fission reaction discovered in 1938 by Otto Hahn, Lise Meitner and their assistant Fritz Strassmann in heavy elements. In 1941, Rubby Sherr, Kenneth Bainbridge and Herbert Lawrence Anderson reported the nuclear transmutation of mercury into gold.

Later in the twentieth century the transmutation of elements within stars was elaborated, accounting for the relative abundance of heavier elements in the universe. Save for the first five elements, which were produced in the Big Bang and other cosmic ray processes, stellar nucleosynthesis accounted for the abundance of all elements heavier than boron. In their 1957 paper Synthesis of the Elements in Stars, William Alfred Fowler, Margaret Burbidge, Geoffrey Burbidge, and Fred Hoyle explained how the abundances of essentially all but the lightest chemical elements could be explained by the process of nucleosynthesis in stars.

Transmutation of other elements into gold

The alchemical tradition sought to turn the "base metal", lead, into gold. As a nuclear transmutation, it requires far less energy to turn gold into lead; for example, this would occur via neutron capture and beta decay if gold were left in a nuclear reactor for a sufficiently long period of time. Glenn Seaborg succeeded in producing a minuscule amount of gold from bismuth, at a net energy loss.

Transmutation in the universe

The Big Bang is thought to be the origin of the hydrogen (including all deuterium) and helium in the universe. Hydrogen and helium together account for 98% of the mass of ordinary matter in the universe, while the other 2% makes up everything else. The Big Bang also produced small amounts of lithium, beryllium and perhaps boron. More lithium, beryllium and boron were produced later, in a natural nuclear reaction, cosmic ray spallation.

Stellar nucleosynthesis is responsible for all of the other elements occurring naturally in the universe as stable isotopes and primordial nuclide, from carbon to uranium. These occurred after the Big Bang, during star formation. Some lighter elements from carbon to iron were formed in stars and released into space by asymptotic giant branch (AGB) stars. These are a type of red giant that "puffs" off its outer atmosphere, containing some elements from carbon to nickel and iron. Nuclides with mass number greater than 64 are predominantly produced by neutron capture processes—the s-process and r-process–in supernova explosions and neutron star mergers.

The Solar System is thought to have condensed approximately 4.6 billion years before the present, from a cloud of hydrogen and helium containing heavier elements in dust grains formed previously by a large number of such stars. These grains contained the heavier elements formed by transmutation earlier in the history of the universe.

All of these natural processes of transmutation in stars are continuing today, in our own galaxy and in others. Stars fuse hydrogen and helium into heavier and heavier elements (up to iron), producing energy. For example, the observed light curves of supernova stars such as SN 1987A show them blasting large amounts (comparable to the mass of Earth) of radioactive nickel and cobalt into space. However, little of this material reaches Earth. Most natural transmutation on the Earth today is mediated by cosmic rays (such as production of carbon-14) and by the radioactive decay of radioactive primordial nuclides left over from the initial formation of the Solar System (such as potassium-40, uranium and thorium), plus the radioactive decay of products of these nuclides (radium, radon, polonium, etc.). See decay chain.

Artificial transmutation of nuclear waste

Overview
Transmutation of transuranium elements (i.e. actinides minus actinium to uranium) such as the isotopes of plutonium (about 1wt% in the light water reactors' used nuclear fuel or the minor actinides (MAs, i.e. neptunium, americium, and curium), about 0.1wt% each in light water reactors' used nuclear fuel) has the potential to help solve some problems posed by the management of radioactive waste by reducing the proportion of long-lived isotopes it contains. (This does not rule out the need for a deep geological repository for high level radioactive waste.) When irradiated with fast neutrons in a nuclear reactor, these isotopes can  undergo nuclear fission, destroying the original actinide isotope and producing a spectrum of radioactive and nonradioactive fission products.

Ceramic targets containing actinides can be bombarded with neutrons to induce transmutation reactions to remove the most difficult long-lived species. These can consist of actinide-containing solid solutions such as , , , ,  or just actinide phases such as , , ,  mixed with some inert phases such as ,, , and . The role of non-radioactive inert phases is mainly to provide stable mechanical behaviour to the target under neutron irradiation.

There are issues with this P&T (partitioning and transmutation) strategy however:
 it is limited by the costly and cumbersome need to separate long-lived fission product isotopes before they can undergo transmutation.
 some long-lived fission products, including the nuclear waste product caesium-137, are unable to capture enough neutrons for effective transmutation to occur due to their small neutron cross-section and resultingly low capture rate.

The new study led by Satoshi Chiba at Tokyo Tech (called "Method to Reduce Long-lived Fission Products by Nuclear Transmutations with Fast Spectrum Reactors") shows that effective transmutation of long-lived fission products can be achieved in fast spectrum reactors without the need for isotope separation. This can be achieved by adding a yttrium deuteride moderator.

Reactor types
For instance, plutonium can be reprocessed into mixed oxide fuels and transmuted in standard reactors. However, this is limited by the accumulation of plutonium-240 in spent MOX fuel, which is neither particularly fertile (transmutation to fissile plutonium-241 does occur, but at lower rates than production of more plutonium-240 from neutron capture by plutonium-239) nor fissile with thermal neutrons. Even countries like  France which practice nuclear reprocessing extensively, usually do not reuse the Plutonium content of used MOX-fuel. The heavier elements could be transmuted in fast reactors, but probably more effectively in a subcritical reactor which is sometimes known as an energy amplifier and which was devised by Carlo Rubbia. Fusion neutron sources have also been proposed as well suited.

Fuel types
There are several fuels that can incorporate plutonium in their initial composition at their beginning of cycle and have a smaller amount of this element at the end of cycle. During the cycle, plutonium can be burnt in a power reactor, generating electricity. This process is not only interesting from a power generation standpoint, but also due to its capability of consuming the surplus weapons grade plutonium from the weapons program and plutonium resulting of reprocessing used nuclear fuel.

Mixed oxide fuel is one of these. Its blend of oxides of plutonium and uranium constitutes an alternative to the low enriched uranium fuel predominantly used in light water reactors. Since uranium is present in mixed oxide, although plutonium will be burnt, second generation plutonium will be produced through the radiative capture of uranium-238 and the two subsequent beta minus decays.

Fuels with plutonium and thorium are also an option. In these, the neutrons released in the fission of plutonium are captured by thorium-232. After this radiative capture, thorium-232 becomes thorium-233, which undergoes two beta minus decays resulting in the production of the fissile isotope uranium-233. The radiative capture cross section for thorium-232 is more than three times that of uranium-238, yielding a higher conversion to fissile fuel than that from uranium-238. Due to the absence of uranium in the fuel, there is no second generation plutonium produced, and the amount of plutonium burnt will be higher than in mixed oxide fuels. However, uranium-233, which is fissile, will be present in the used nuclear fuel. Weapons-grade and reactor-grade plutonium can be used in plutonium–thorium fuels, with weapons-grade plutonium being the one that shows a bigger reduction in the amount of plutonium-239.

Long-lived fission products

Some radioactive fission products can be converted into shorter-lived radioisotopes by transmutation. Transmutation of all fission products with half-life greater than one year is studied in Grenoble, with varying results.

Strontium-90 and caesium-137, with half-lives of about 30 years, are the largest radiation (including heat) emitters in used nuclear fuel on a scale of decades to ~305 years (tin-121m is insignificant because of the low yield), and are not easily transmuted because they have low neutron absorption cross sections. Instead, they should simply be stored until they decay. Given that this length of storage is necessary, the fission products with shorter half-lives can also be stored until they decay.

The next longer-lived fission product is samarium-151, which has a half-life of 90 years, and is such a good neutron absorber that most of it is transmuted while the nuclear fuel is still being used; however, effectively transmuting the remaining  in nuclear waste would require separation from other isotopes of samarium. Given the smaller quantities and its low-energy radioactivity,  is less dangerous than  and  and can also be left to decay for ~970 years.

Finally, there are seven long-lived fission products. They have much longer half-lives in the range 211,000 years to 15.7 million years. Two of them, technetium-99 and iodine-129, are mobile enough in the environment to be potential dangers, are free (Technetium has no known stable isotopes) or mostly free of mixture with stable isotopes of the same element, and have neutron cross sections that are small but adequate to support transmutation.
Additionally,  can substitute for uranium-238 in supplying Doppler broadening for negative feedback for reactor stability.
Most studies of proposed transmutation schemes have assumed , , and transuranium elements as the targets for transmutation, with other fission products, activation products, and possibly reprocessed uranium remaining as waste. Technetium-99 is also produced as a waste product in nuclear medicine from Technetium-99m, a nuclear isomer that decays to its ground state which has no further use. Due to the decay product of  (the result of  capturing a neutron) decaying with a relatively short half life to a stable isotope of ruthenium, a precious metal, there might also be some economic incentive to transmutation, if costs can be brought low enough.

Of the remaining five long-lived fission products, selenium-79, tin-126 and palladium-107 are produced only in small quantities (at least in today's thermal neutron, -burning light water reactors) and the last two should be relatively inert. The other two, zirconium-93 and caesium-135, are produced in larger quantities, but also not highly mobile in the environment. They are also mixed with larger quantities of other isotopes of the same element. Zirconium is used as cladding in fuel rods due to being virtually "transparent" to neutrons, but a small amount of  is produced by neutron absorption from the regular zircalloy without much ill effect. Whether  could be reused for new cladding material has not been subject of much study thus far.

Nuclear transmutation


Andhra Pradesh (,  abbr. AP) is a state in the southern coastal region of India. It is the seventh-largest state with an area of  and the tenth-most populous state with 49,577,103 inhabitants. It has shared borders with  Chhattisgarh, Odisha, Karnataka, Tamil Nadu, Telangana and the Bay of Bengal. It has the second-longest coastline in India at about .  After existence as Andhra State and unified Andhra Pradesh, the state took its present form on 2 June 2014, when the new state of Telangana was formed through bifurcation.  Amaravati is the capital of the state, with the largest city being Visakhapatnam. Water sharing disputes and asset division with Telangana are not yet resolved. Telugu, one of the classical languages of India used by the majority of people, is the first official language.

As per the 8th century BCE Rigvedic text Aitareya Brahmana, the Andhras left North India off the banks of the Yamuna river and migrated to South India. In the third century BCE, Andhra was a vassal kingdom of Ashoka of the Mauryan Empire. After his death, it became powerful and extended its empire to the whole Maratha country and beyond under the rule of the Satavahana dynasty. After that, the major rulers included the Pallavas, Eastern Chalukyas, Kakatiyas, Vijayanagara Empire, Qutb Shahi dynasty, Nizam dynasty, East India Company, and British Raj.

The Eastern Ghats are a major dividing line separating coastal plains and peneplains. The coastal plains are part of Coastal Andhra. These are mostly delta regions formed by the Krishna, Godavari, and Penna rivers. Peneplains are part of Rayaaseema. 60% of the population is engaged in agriculture and related activities. Rice is the state's major food crop and staple food. The state contributes 10% of total fish production and over 70% of shrimp production in India. Industry sectors such as food products, non-metallic minerals, textiles, and pharmaceuticals are the top employment providers. The automotive sector accounts for 10% of India's auto exports. The state has about one-third of India's limestone reserves, large deposits of baryte and galaxy granite, and reserves of oil and natural gas. Satish Dhawan Space Centre (SDSC), known as Sriharikota Range (SHAR), at the barrier island of Sriharikota in Tirupati district, is the satellite launching station of India.

Some of the unique products from the state are Banaganapalle mangoes, Bandar laddu, Kondaplli toys, Tirupati laddu, and saris made in Dharmavaram and Machilipatnam. Kuchipudi is the official dance form. Many composers of Carnatic music, like Annamacharya, Kshetrayya, and Tyagaraja, were from this region. The Tirumala Venkateswara temple near Tirupati is the most visited Hindu religious place in the world. The state is home to a variety of other pilgrimage centres and natural attractions.

Etymology
According to the Sanskrit text Aitareya Brahmana (800–500 BCE), a group of people named Andhras left North India off the banks of the Yamuna and settled in South India. The Satavahanas were mentioned by the names Andhra, Andhrara-jateeya, and Andhrabhrtya in the Puranic literature. They did not refer to themselves as Andhra in any of their coins or inscriptions; it is possible that they were termed as Andhras because of their ethnicity or because their territory included the Andhra region.

History

Early and medieval history

The Assaka mahajanapada, one of the sixteen Vedic mahajanapadas, included Andhra Pradesh, Maharashtra, and Telangana. Archaeological evidence from places such as Bhattiprolu, Amaravati, Dharanikota, and Vaddamanu suggests that the Andhra region was part of the Mauryan empire. Amaravati might have been a regional centre under Mauryan rule. After the death of Emperor Ashoka, Mauryan rule weakened around 200 BCE and was replaced by several smaller kingdoms in the Andhra region. One of the earliest examples of the Brahmi script, the progenitor of several scripts, including Telugu, comes from Bhattiprolu, where the script was used on an urn containing the relics of Buddha.

The Satavahana dynasty dominated the Deccan plateau from the 1st century BCE to the 3rd century CE. It had trade relations with the Roman Empire. The later Satavahanas made Dharanikota, near Amaravati, their capital. According to the Buddhists, Nagarjuna, the philosopher of Mahayana, lived in this region. The Andhra Ikshvakus, with their capital at Vijayapuri, succeeded the Satavahanas in the Krishna River valley in the latter half of the 2nd century. The Salankayanas were an ancient dynasty that ruled the Andhra region between Godavari and Krishna with their capital at Vengi (modern Pedavegi) from 300 to 440 CE. Telugu Cholas ruled present-day Rayalaseema from the fifth to the eleventh centuries from Cuddapa and Jammalamadugu. The Telugu inscription of Erikal Mutturaju Dhananjaya Varma, known as Erragudipadu , was engraved in 575 CE in the present Kadapa district. It is the earliest written record in Telugu.

The Vishnukundinas were the first dynasty in the fifth and sixth centuries to hold sway over most of Andhra Pradesh, Kalinga, and parts of Telangana. The Eastern Chalukyas of Vengi, whose dynasty lasted for around five hundred years from the 7th century until 1130 CE, eventually merged with the Chola dynasty. They continued to rule under the protection of the Chola dynasty until 1189 CE.  At the request of King Rajaraja Narendra, Nannaya, considered the first Telugu poet, took up the translation of the Mahabharata into Telugu in 1025 CE.

Kakatiyas ruled this region and Telangana for nearly two hundred years between the 12th and 14th centuries. They were defeated by the Delhi Sultanate. Musunuri Nayaks and Bahamani Sultanate took over when Delhi Sultanate became weak. The Reddi kingdom ruled parts of this region in the early 14th century. They constructed Kondaveedu Fort and Kondapalli Fort. After their rule, Gajpathis and Bahmani sultans ruled this region in succession before this region, along with most of present-day Andhra Pradesh, became part of the Vijayanagar empire.

The Vijayanagara empire originated on the Deccan plateau in the early 14th century. It was established in 1336 by Harihara Raya I and his brother Bukka Raya I of the Sangama dynasty, who served as treasury officers of the Kakatiyas of Warangal. During their rule, the Pemmasani Nayaks controlled parts of Andhra Pradesh and had large mercenary armies that were the vanguard of the empire in the 16th century. The empire's patronage enabled fine arts and literature to reach new heights in Kannada, Telugu, Tamil, and Sanskrit, while Carnatic music evolved into its current form. The Lepakshi group of monuments built during this period have mural paintings of the Vijayanagara kings, Dravidian art, and inscriptions. These are put on the tentative list of the UNESCO World Heritage Committee.

Modern history

Following the defeat of the Vijayanagara empire, the Qutb Shahi dynasty held sway over Andhra Pradesh. This region passed under the rule of the Nizams under the Mughal Empire. Soon, Nizam established himself as the sovereign ruler. In 1611, an English trading post by the name of "East India Company" was established in Masulipatinam on India's east coast. In the early nineteenth century, Northern Circars was ceded to the British East India Company and became part of its Madras Presidency. Eventually, this region emerged as the Coastal Andhra region, the northern parts of which were later known as Uttarandhra. Later, the Nizam ceded five territories to the British, which eventually became the Rayalaseema region. The local chieftains, known as Poligars, revolted in 1800 against the company's rule, which was suppressed by the company.
Raja Viziaram Raz (Vijayaram Raj) established a sovereign kingdom by claiming independence from the Kingdom of Jeypore in 1711. It formed alliances with the French and British East India Companies to conquer the neighbouring principalities of Bobbili, Kurupam, Paralakhemundi, and the kingdom of Jeypore. It fell out with the British and, as a result, was attacked and defeated in the battle of Padmanabham. It was annexed as a tributary estate like other principalities and remained so until their accession to the Indian Union in 1949.

Following the Indian rebellion of 1857, the British crown ruled this region, until India became independent in 1947. The No Tax Campaign in Chirala and Perala in 1919, led by Duggirala Gopalakrishnayya, the Rampa Revolt led by Alluri Sitarama Raju in 1921, and the Salt Satyagraha in Dendulur in 1930 are some of the protests against British rule. Tanguturi Prakasam was arrested and jailed for more than three years for participating in the Quit India movement of 1942. He served as prime minister of the Madras presidency in 1946–47.

Dowleswaram Barrage, built in 1850 by Arthur Cotton, brought unused lands in the Godavari river basin into cultivation and transformed the economy of the region. Charles Philip Brown did pioneering work in transforming Telugu to the print era and introduced Vemana poems to English readers. Kandukuri Veeresalingam is considered the father of the Telugu Renaissance Movement, as he encouraged the education of women and the remarriage of widows and fought against child marriage and the dowry system. Gurajada Apparao, a pioneering playwright who used spoken dialect, wrote the play Kanyasulkam in 1892. It is considered the greatest play in the Telugu language.

Post-independence

In an effort to gain an independent state based on linguistic identity and to protect the interests of the Telugu-speaking people of Madras State, Potti Sreeramulu fasted to death in 1952. The Telugu-speaking area of Andhra State was carved out of Madras State on 1 October 1953, with Kurnool as its capital city. Tanguturi Prakasam became the first chief minister. On the basis of the Gentlemen's Agreement of 1956, the States Reorganisation Act created Andhra Pradesh by merging the neighbouring Telugu-speaking areas of the Hyderabad State with Hyderabad as the capital on 1 November 1956.

The Indian National Congress (INC) ruled the state from 1956 to 1982. Neelam Sanjiva Reddy became the first chief minister. Among Congress chief ministers, P. V. Narasimha Rao is known for implementing land reforms and land ceiling acts and securing reservation for lower castes in politics. In 1983, the Telugu Desam Party (TDP) won the state elections, and N. T. Rama Rao became the chief minister of the state for the first time after launching his party just nine months earlier. This broke the long-time single-party monopoly enjoyed by the INC. He transformed the sub-district administration by forming mandals in place of earlier taluks, removing hereditary village heads, and appointing non-hereditary village revenue assistants.  Nara Chandrababu Naidu, Rao's son-in-law, came to power in 1995 with the backing of a majority of the MLAs. He introduced e-governance by launching e-Seva centres in 2001 for paperless and speedy delivery of government services. He is credited with transforming Hyderabad into an IT hub by providing incentives for tech companies to set up centres. In 2004, Congress returned to power with a new chief ministerial face, YS Rajashekara Reddy, better known as YSR. The main emphasis during Reddy's tenure was on social welfare schemes such as free electricity for farmers, health insurance, tuition fee reimbursement for the poor, and the national rural employment guarantee scheme. He was elected chief minister again but was killed in a helicopter crash that occurred in September 2009.

During its 58 years as a unified state, the state weathered separatist movements from Telangana (1969) and Andhra (1972) successfully. A new party called Telangana Rashtra Samithi, formed in April 2001 by Kalvakuntla Chandrashekar Rao (KCR), reignited the Telanganga movement. When the central government decided to initiate the process to form an independent Telangana in December 2009, Samaikyandhra movement to keep the state united took shape. The agitations continued for nearly 5 years, with the Telangana side harping on the marginalisation of food culture, language, and unequal economic development and the Samaikyandhra movement focusing on the shared culture, language, customs, and historical unity of Telugu-speaking regions. The Andhra Pradesh Reorganisation Act bill was passed by the parliament of India for the formation of the Telangana state, comprising ten districts, despite opposition by the state legislature.  The new state of Telangana came into existence on 2 June 2014 after approval from the president of India, with the residual state continuing as Andhra Pradesh.

In the final elections held in the unified state in 2014, the TDP got a mandate in its favour, defeating its nearest rival, the YSR Congress Party, a breakaway faction of the Congress founded by Y. S. Jagan Mohan Reddy, son of former Chief Minister Y. S. Rajasekhara Reddy. N. Chandrababu Naidu, the chief of the TDP, became the chief minister on 8 June 2014. In 2017, the government of Andhra Pradesh began operating from its new greenfield capital, Amaravati, for which 33,000 acres were acquired from farmers through an innovative land pooling scheme. Interstate issues with Telangana relating to the division of assets of public sector institutions and organisations of the united state and the division of river waters are not yet resolved.

Geography

The state is bordered by Telangana to the north and west, Chhattisgarh and Orissa to the north, the Bay of Bengal to the east, Tamil Nadu to the south, and Karnataka to the west. Yanam district, an enclave of Puducherry, is in the state bordering Kakinada district. It has a coastline of around , which makes it the second-longest coastline in the nation.

The Eastern Ghats are a major dividing line separating coastal plains and peneplains in the state's geography. The Eastern Coastal Plains comprise the area of coastal districts up to the Eastern Ghats as their border along the Bay of Bengal, with variable width. These are, for the most part, delta regions formed by the Krishna, Godavari, and Penna rivers. Most of the coastal plains are put to intensive agricultural use. The Eastern Ghats are discontinuous, and individual sections have local names. The ghats become more pronounced towards the south and extreme north of the coast. These consist of the Papikonda range, the Simhachal hill range, the Yarada hills, the Nallamala Hills, the Papi hills, the Seshachala hills, and the Horsley hills. The Kadapa Basin, formed by two arching branches of the Eastern Ghats, is a mineral-rich area. Peneplains, part of Rayalaseema, slope towards the east, with the Eastern Ghats as their eastern border.

Flora and fauna

The total forest cover of the state is , amounting to 18.28% of the total area. The Eastern Ghats region is home to dense tropical forests, while the vegetation becomes sparse as the ghats give way to the peneplains, where shrub vegetation is more common. The vegetation found in the state is largely of dry deciduous types, with a mixture of teak, Terminalia, Dalbergia, Pterocarpus, Anogeissus, etc. The state possesses some rare and endemic plants like Cycas beddomei, Pterocarpus santalinus, Terminalia pallida, Syzygium alternifolium, Shorea talura, Shorea tumburgia, Psilotum nudum, etc. Coringa is an example of mangrove forests and salt-tolerant forest ecosystems near the sea. The area of these forests is , accounting for about 9% of the local forest area of the state.

The diversity of fauna includes tigers, leopards, Dholess, black bucks, cheetals, sambars, sea turtles, and a number of birds and reptiles. The estuaries of the Godavari and Krishna rivers support rich mangrove forests with fishing cats and otters as keystone species. The state has many sanctuaries and national parks, such as Coringa, Nagarjunsagar-Srisailam Tiger Reserve, Kolleru Bird Sanctuary, and Nelapattu Bird Sanctuary.

Mineral resources

The state, with its varied geological formations, contains a variety of industrial minerals and building stones. It is listed at the top of the list of mica deposits in India. Minerals found in the state include limestone, manganese, asbestos, iron ore, ball clay, fire clay, gold, diamonds, graphite, dolomite, quartz, tungsten, steatitic, feldspar, and silica sand. It has reserves of oil and natural gas. It has about one-third of India's limestone reserves and is known for large exclusive deposits of baryte and galaxy granite. The largest reserves of uranium are in Tummalapalli village, Vemula mandal, of YSR district.

Climate
The climate varies considerably, depending on the geographical region. Summers last from March to June. In the coastal plain, the summer temperatures are generally higher than in the rest of the state, with temperatures ranging between . July to September is the season for tropical rains from the southwest monsoon. During October to December, low-pressure systems and tropical cyclones form in the Bay of Bengal along with the northeast monsoon, bringing rains to the southern and coastal regions of the state. November to February are the winter months. Since the state has a long coastal belt, the winters are not very cold. The range of winter temperatures is generally . Lambasingi in Visakhapatnam district is nicknamed the "Kashmir of Andhra Pradesh" as its temperature ranges from . The normal rainfall for the state is , and the actual rainfall for June 2020–May 2021 was .

Demographics

Based on the 2011 Census of India, the population of Andhra Pradesh is 49,577,103, with a density of . 70.53% of the population is rural, and 29.47% is urban. The state has 17.08% Scheduled Caste and 5.53% Scheduled Tribe populations. Children in the age group of 0–6 years number 5,222,384, constituting 10.6% of the total population.

Amaravati protests

In August 2020, the Andhra Pradesh legislative assembly passed the Andhra Pradesh decentralisation and inclusive development of all regions act. It provided for limiting Amaravati as legislative capital while naming Vizag as executive capital and Kurnool as judicial capital.

Telangana selectively accepted the recommendations, while Andhra Pradesh is asking for their acceptance in total. The division of the RTC headquarters and the Deccan Infrastructure and Landholdings Limited (DIL) with huge land parcels has become contentious. Despite several meetings of the trilateral dispute resolution committees, no progress was made. The Andhra Pradesh government filed a suit in the Supreme Court.

Krishna river water sharing dispute

Andhra Pradesh and Telangana continue to dispute the water share of the Krishna River. In 1969, the Bachawat tribunal for the allocation of water shares among the riparian states allocated 811 tmcft of water to Andhra Pradesh. The Andhra Pradesh government of that time split it in a 512:299 tmcft ratio between Andhra Pradesh (including the basin area of Rayalaseema) and Telangana, respectively. It was based on the utilisation facilities established at that time. Though the tribunal recommended the use of the Tungabhadra Dam (a part of the Krishna Basin) to provide water to the drought-prone Mahabubnagar area of Telangana, this was not implemented. The bifurcation act advised the formation of the Krishna River Management Board (KRMB) and the Godavari River Management Board (GRMB) for resolving disputes between the new states. In 2015, the two states agreed to share water in the 66:34 (AP:Telangana) ratio as an interim arrangement in a meeting with the central water ministry, which is to be reviewed every year. This practice continued without further review. Telangana filed a suit in the Supreme Court for a 70% share. Following the assurance of the formation of a tribunal to resolve the issue, Telangana withdrew its suit. The centre has yet to form the tribunal.

Godavari water sharing dispute

Andhra Pradesh got 1172.78 tmcft of Godavari water. Telangana is utilising 433 tmcft for its completed projects, while Andhra Pradesh's share is 739 tmcft. The Andhra Pradesh government has opposed Telangana submitting a detailed project report for additional utilisation through new or upgraded projects such as Kaleswaram, Tupakulagudem, Sitarama, Mukteswaram, and Modikunta lift irrigation projects.

Five villages near Bhadrachalam
The 1.50-metre increase in the height of the Polavaram coffer dam to 44 metres raised the suspicion that it led to flooding of Bhadrachalam and nearby villages in Telangana along the Godavari river in 2022. Three mandals that were originally part of Andhra State were transferred back to Andhra Pradesh, excluding Bhadrachalam town, to support the Polavaram project, as those areas are likely to be submerged. Telangana would like to take back five villages on the river banks for ease of movement of its government machinery to provide rehabilitation support to its other villages beyond them, to which the Andhra Pradesh government is objecting.

"Naatu Naatu" from the film RRR became the first song from an Indian film to win the Academy Award for Best Original Song and the Golden Globe Award for Best Original Song, as well as the first song from an Asian film to win the former.

Cuisine

Andhra meals are combinations of spicy, tangy, and sweet flavours. Chillies, which are abundantly produced in Andhra Pradesh, and curry leaves are used copiously in most preparations of curries and chutneys. Various types of Pappu are made using lentils in combination with tomatoes, spinach, gongura, ridge gourd, etc. Apart from curries, pulusu, a stew made using tamarind juice in combination with vegetables, sea food, chicken, mutton, etc., is popular. Pachchadi, a paste usually made with a combination of groundnuts, fried vegetables, and chillies, is a must in a meal. Pickles made using mangoes, gooseberries, lemons, etc. are enjoyed in combination with Pappu. Buttermilk and yoghurt mixed with rice and eaten towards the end of the meal soothe the body, especially after eating spicy food items earlier. Ariselu, Burelu, Laddu, and Pootharekulu are some of the sweets made for special festivals and occasions.

Tourism

Some of the popular religious pilgrim destinations include Tirumala Venkateswara temple at Tirupati, Srikalahasti temple, Varaha Lakshmi Narasimha temple, Simhachalam, Shahi Jamia Masjid in Adoni, Gunadala Church in Vijayawada, and Buddhist centres at Amaravati and Nagarjuna Konda. Tirumala Venkateswara temple is the world's most visited Hindu temple, with footfalls of 30,000–40,000 daily and about 75,000 on New Year's Eve. The region is home to a variety of other pilgrimage centres, such as the Pancharama Kshetras, Mallikarjuna Jyotirlinga, Kanaka Durga Temple and Kodanda Rama Temple.

The state has several beaches in its coastal districts, such as Rushikonda, Mypadu, Suryalanka, etc.; caves such as Borra Caves; Indian rock-cut architecture depicting Undavalli Caves; and the country's second-longest cave system, the Belum Caves. The valleys and hills include Araku Valley, Horsley Hills, Papi Hills, and Gandikota Gorge. Arma Konda, located in Visakhapatnam district, is the highest peak in the Eastern Ghats.

Museums

The state has 32 museums, which feature a varied collection of ancient sculptures, paintings, idols, weapons, cutlery, inscriptions, and religious artefacts. The Amaravati Archaeological Museum has several archaeological artefacts. Visakha Museum and Telugu Samskruthika Niketanam in Visakhapatnam display historical artefacts of the pre-independence era. Bapu Museum in Vijayawada displays a large collection of artefacts. Advanced projection mapping with graphic, animation, and laser displays is used to tell the history of Kondapalli Fort, utilising the irregular landscapes, ruins, and buildings present in the fort as a screen. It was launched in 2019.

The Archaeological Survey of India identified 135 centrally protected monuments in the state of Andhra Pradesh. These include the reconstructed monuments at Anupu and Nagarjunakonda.

Sports

The Sports Authority of Andhra Pradesh is the governing body that looks after the infrastructure development, coaching, and administration of sports promotion schemes. Dr. YSR Sports School, with classes for grades 4–10 and a focus on tapping rural sports talent, was established in Putlampalli, YSR district, in December 2006.

The ACA-VDCA stadium in Visakhapatnam hosted ODI, T20I, and IPL matches. Andhra Pradesh secured 16 medals at the 36th National Games held in 2022. It was ranked twenty-first in the competition. It won the most medals in athletics. Two silvers and one bronze were won in weightlifting.

Karnam Malleswari is the first female Indian to win an Olympic medal. Pullela Gopichand is a former Indian badminton player. He won the All England Open Badminton Championships in 2001, becoming the second Indian to win after Prakash Padukone. Srikanth Kidambi, a badminton player, is the first Indian to reach the world championships final in 2021 in the men's singles and win a silver medal.

In mathematics, especially in set theory, two ordered sets  and  are said to have the same order type if they are order isomorphic, that is, if there exists a bijection (each element pairs with exactly one in the other set)  such that both  and its inverse are monotonic (preserving orders of elements).

In the special case when  is totally ordered, monotonicity of  already implies monotonicity of its inverse.

One and the same set may be equipped with different orders. Since order-equivalence is an equivalence relation, it partitions the class of all ordered sets into equivalence classes.

Notation
If a set  has order type denoted , the order type of the reversed order, the dual of , is denoted .

The order type of a well-ordered set  is sometimes expressed as .

Examples
The order type of the integers and rationals is usually denoted  and , respectively. The set of integers and the set of even integers have the same order type, because the mapping  is a bijection that preserves the order.  But the set of integers and the set of rational numbers (with the standard ordering) do not have the same order type, because even though the sets are of the same size (they are both countably infinite), there is no order-preserving bijective mapping between them. The open interval  of rationals is order isomorphic to the rationals, since, for example,  is a strictly increasing bijection from the former to the latter. Relevant theorems of this sort are expanded upon below.

More examples can be given now: The set of positive integers (which has a least element), and that of negative integers (which has a greatest element). The natural numbers have order type denoted by ω, as explained below.

The rationals contained in the half-closed intervals [0,1) and (0,1], and the closed interval [0,1], are three additional order type examples.

Order type of well-orderings

Every well-ordered set is order-equivalent to exactly one ordinal number, by definition. The ordinal numbers are taken to be the canonical representatives of their classes, and so the order type of a well-ordered set is usually identified with the corresponding ordinal. Order types thus often take the form of arithmetic expressions of ordinals.

Examples
Firstly, the order type of the set of natural numbers is . Any other model of Peano arithmetic, that is any non-standard model, starts with a segment isomorphic to ω but then adds extra numbers. For example, any countable such model has order type .

Secondly, consider the set  of even ordinals less than :

As this comprises two separate counting sequences followed by four elements at the end, the order type is

Rational numbers
With respect to their standard ordering as numbers, the set of rationals is not well-ordered. Neither is the completed set of reals, for that matter.

Any countable totally ordered set can be mapped injectively into the rational numbers in an order-preserving way. When the order is moreover dense and has no highest nor lowest element, there even exist a bijective such mapping.

Michael Heffernan is an Irish sportsperson.  He plays hurling with his local club Nenagh Éire Óg and with the Tipperary senior inter-county team.

Career
Heffernan won two All-Ireland Minor Hurling medals in 2006 and 2007. He made his National Hurling League debut as a substitute against Limerick in 2010, scoring a point from play.
He went on to make his Championship debut on 3 July 2010 against Wexford in the 2010 All-Ireland Senior Hurling Championship Qualifiers.

On 28 July 2010, Heffernan played at corner forward, scoring 1-3 for Tipperary as they defeated Clare in the 2010 Munster Under-21 Hurling final at Semple Stadium, winning by 1–22 to 1–17.

On 5 September 2010, Heffernan was a non-playing substitute as Tipperary won their 26th All Ireland title, beating reigning champions Killkenny by 4–17 to 1–18 in the final, preventing Kilkenny from achieving an historic 5-in-a-row, it was Heffernan's first All-Ireland winners medal. Six day's later on 11 September 2010, Tipperary clinched the All Ireland Under-21 title by defeating Galway by 5–22 to 0–12 at Semple Stadium, with Heffernan starting at corner forward scoring two points.

In 2012, Heffernan was part of the Tipperary team that won the Munster Intermediate Hurling Championship and the All-Ireland Intermediate Hurling Championship.
He started the All-Ireland final at full forward and scored one goal and four points in the 3–13 to 1–17 victory against Kilkenny at Semple Stadium.
Heffernan created a piece of history by adding the All-Ireland Intermediate medal (2012) to the  Minor (2006, 2007), Under-21 (2010) and Senior (2010) titles that he had already won.

The Euripus Strait ( ) is a narrow channel of water separating the Greek island of Euboea in the Aegean Sea from Boeotia in mainland Greece. The strait's principal port is Chalcis on Euboea, located at the strait's narrowest point.

The strait is subject to strong tidal currents which reverse direction approximately four times a day. Tidal flows are very weak in the Eastern Mediterranean, but the strait is a remarkable exception.  Water flow peaks at about , either northwards or southwards, and lesser vessels are often incapable of sailing against it.  When nearing flow reversal, sailing is even more precarious because of vortex formation.

The Swiss scholar François-Alphonse Forel contributed to an understanding of the enigmatic phenomenon by his study of limnology and the discovery of seiche, where layers of water of differing temperature oscillate in thickness in a confined body of water. But the problem was solved completely only by D. Eginitis, director of the Athens Observatory, who published his conclusions in 1929.

Etymology
From Ancient Greek  (eúrīpos, "any strait or narrow sea, where the flux and reflux is violent"); from  (eû, "well") +  (rhipḗ, "swing or force with which anything is thrown"), from  (rhíptō, "to throw").

Bridges
There are two road bridges across the strait, both at Chalcis. One is the Euripus Bridge or Chalcis Bridge, a two-pylon, cable-suspended bridge built south of town in 1992, and commonly called the "New" or "High" bridge, with a span of about 215 m (705 ft). The strait is 160 m (525 ft) wide at this point.  The bridge is accessible via a fork on the main road at Aulis.

The "Old" or "Low" or "Sliding" Bridge lies across midtown, and can slide away to allow shipping traffic. It is located at the narrowest point of the strait, where it is only 38 m (125 ft) wide.  It accommodates two lanes of vehicular traffic.  It was originally built as a retractable bridge in 1858, replaced by a rotating one in 1896.  The existing, originally wooden bridge was built in 1962 and was extensively refurbished in 1998.

History
The Euripus was closed by a dike of coarse sediment until about 6000 years ago, when it was opened by an (unrecorded) earthquake. Herodotus mentions the strait during his description of the Battle of Artemisium (480 BC), with the account implying that it was navigable by large fleets of triremes. Diodorus Siculus reports that in 411 BC the Euboeans closed the strait by mostly rebuilding the dike, with the goal of making themselves part of Boeotia, therefore not an island subject to Athenian hegemony. Diodorus states that gaps had to be left in the dike to allow the Euripus tides to flow through; the narrowness of the remaining passage made the current much more intense. Only a single passage was left navigable, just wide enough for a single ship. There is no mention of the closure of the strait in either Thucydides' History of the Peloponnesian War or Xenophon's Hellenica. Strabo wrote that at an unspecified later date the strait was crossed by a bridge two plethra long (approximately , which is probably an exaggeration). Some vestiges of the artificial dike probably remained, so the gap spanned by the bridge could have been narrower than the channel that existed before 411 BC. Ancient historians do not record the depth of the channel; even the passage under Strabo's bridge may have been scoured by the tides to a depth sufficient for ancient shipping.

Procopius reports that during the reign of Emperor Justinian I (527 to 565 AD) there were two channels in the Euripus, the large original channel and a new narrower cleft to the east of it, so narrow that it could be crossed with a single plank of wood. This later stream was later widened to make the present shipping channel. At the time when Procopius wrote, the name of the fortress on the Euripus was probably "Euripus," which had become "Egripos" by 1204, and was adopted and slightly altered to "Nigriponte" by the Latins who occupied the place in 1205.  (The name has nothing to do with any sort of "Black Bridge," except as a Veronese or Venetian joke, or folk-etymological corruption or re-interpretation in reference to the old bridge across the channel.)

In 1395, Nicola di Martoni came to Negropont during the return from his pilgrimage to Egypt and Palestine.  He is clear that the main shipping channel in the Venetian period was on the side of the Boeotian mainland, and mentions the mills on the narrower channel, which he says were sometimes broken in the speed and turbulence of the flow there.

We have further information about the shipping channel and its single wooden bridge from various documents in the archives of the Venetian Empire. In 1408, the formation of a reef under the bridge severely affected shipping (http://www.archiviodistatovenezia.it/divenire/collezioni.htm  Senato, Deliberazioni, Misti. 48,43v) and in 1439 there was concern over the tendency of the current to erode the surroundings of the pilings that supported the bridge  (http://www.archiviodistatovenezia.it/divenire/collezioni.htm  Senato, Deliberazioni, Misti. 60,140r–42r).

Evliya Çelebi, in his Travel Journal (SN VIII250a27, ff.), tells us that the narrow channel was first opened out enough for a galley to pass through at some time in the late 16th century, and was still just barely wide enough at the time of his visit in 1668 for a galley to squeeze through, even though the old shipping channel had been abandoned.
By the end of the 18th century it was well on its way to being the width of the modern channel.

Archaeal translation is the process by which messenger RNA is translated into proteins in archaea. Not much is known on this subject, but on the protein level it seems to resemble eukaryotic translation.

Most of the initiation, elongation, and termination factors in archaea have homologs in eukaryotes. Shine-Dalgarno sequences only are found in a minority of genes for many phyla, with many leaderless mRNAs probably initiated by scanning. The process of ABCE1 ATPase-based recycling is also shared with eukaryotes.

Being a prokaryote without a nucleus, archaea do perform transcription and translation at the same time like bacteria do.

The Capt. Joel Whitney House is a historic house at 8 Pleasant Street in Phillips, Maine.  Built in 1829 for a prominent early settler and businessman, it is one of the oldest houses in the small inland community, and probably the only two-story building of that age.  It is now owned by the Phillips Historical Society, which houses museum displays in the rear sections.  The house was listed on the National Register of Historic Places in 2003.

Description and history
The Whitney House is set at the southeast corner of Pleasant and Sawyer Streets, opposite Sawyer Street from the Union Church.  The house is a rambling structure, with a -story side-gable main block, a long single-story ell extending to the rear, which joins to a square two-story carriage house with a cupola-topped hip roof.  The main facade is five bays wide, with a central entrance flanked by sidelight windows and topped by a wooden fan set in an elaborate entablature in the Federal style.  The rear ell was built in two stages, the first being integral to the house construction and the second added later.  The carriage house has large sliding doors on two sides, with a large hay portal over the southern entrance.  The interior of the main house has retained much of its original Federal period woodwork and hardware; the rear sections have been adapted for use as display, meeting, and library spaces by the historical society.

The town of Phillips was incorporated in 1812.  Captain Joel Whitney arrived with his family sometime between 1806 and 1815, bought  of land, and soon became a man of local prominence.  Lands he owned became part of Phillips village, he operated a saw mill and potash factory, and he served as an early postmaster.  He donated the land for the adjacent Union Church, helped finance its construction, and donated the bell in its tower.  This house was built for Whitney in 1829 by Jesse Ladd, a local housewright, some of whose other houses have survived.  This is the only known two-story house of the period to survive in Phillips—all the others are -story Capes.

Sir Richard Biddulph Martin, 1st Baronet (12 May 1838 – 23 August 1916) was an English banker and Liberal Party (and later Liberal Unionist) politician.

Martin was the older of two sons of Robert Martin (1808–1897) of Overbury Court near Tewkesbury in Gloucestershire and his wife, Mary Ann (d. 1892), who was the daughter of John Biddulph of the banking firm of Cocks, Biddulph & Co. His younger brother John Biddulph Martin was also a banker and statistician.  Robert Martin was a partner of the Grasshopper Bank, which later became Martins Bank.

He was educated at Harrow School and at Exeter College, Oxford, before joining his maternal grandfather's bank. He later became one of the founders of the British North Borneo Company and of the Institute of Bankers.

Martin first stood for election to the House of Commons at the 1868 general election, when he was an unsuccessful candidate in the Eastern division of Worcestershire. He was unsuccessful again in next candidacy, at the 1880 general election in the City of London.

However, 3 months later he was elected as Member of Parliament (MP) for Tewkesbury at a by-election held in July 1880 after the result of the general election in April was overturned on petition. Several of his ancestors had held the seat in the past, but Richard was the last Martin to represent Tewkesbury. The Parliamentary Borough of Tewkesbury was abolished under the Reform Act 1885 and replaced with a wider county division of Gloucestershire.

At the 1885 general election, he did not stand for re-election in the new Tewkesbury division of Gloucestershire, contesting instead the Chelmsford division of Essex, but without success.

When the Liberal Party split over Irish Home Rule, he joined the breakaway Liberal Unionist Party, and stood as a Liberal Unionist in the Ashburton division of Devon, again without success. He finally returned to Parliament at the  1892 general election as MP for the Droitwich division of Worcestershire, replacing the Liberal Unionist John Corbett, who had retired. Martin remained Droitwich's MP until he stood down at the 1906 general election.

He was made a baronet on 12 December 1905, of Overbury Court, in Gloucestershire. He died childless, and the title became extinct on his death.

He was Prime Warden of the Fishmongers' Company from 1899 to 1900, and President of the Royal Statistical Society from 1906 to 1907.
