In modern medicine, a surgeon is a physician who performs surgical operations. There are surgeons in podiatry, dentistry maxillofacial surgeon and the veterinary fields; the first person to document a surgery was Sushruta. He specialized in cosmetic plastic surgery and had documented an operation of open rhinoplasty, his magnum opus Suśruta-saṃhitā is one of the most important surviving ancient treatises on medicine and is considered a foundational text of Ayurveda and surgery. The treatise addresses all aspects of general medicine, but the translator G. D. Singhal dubbed Suśruta "the father of surgical intervention" on account of the extraordinarily accurate and detailed accounts of surgery to be found in the work. After the eventual decline of the Sushruta School of Medicine in India, surgery had been ignored until the Islamic Golden Age surgeon Al-Zahrawi, reestablished surgery as an effective medical practice, he is considered the greatest medieval surgeon to have appeared from the Islamic World, has been described as the father of surgery.
His greatest contribution to medicine is the Kitab al-Tasrif, a thirty-volume encyclopedia of medical practices. He was the first physician to describe an ectopic pregnancy, the first physician to identify the hereditary nature of hæmophilia, his pioneering contributions to the field of surgical procedures and instruments had an enormous impact on surgery but it was not until the eighteenth century that surgery as a distinct medical discipline emerged in England. In Europe, surgery was associated with barber-surgeons who used their hair-cutting tools to undertake surgical procedures at the battlefield and for their employers. With advances in medicine and physiology, the professions of barbers and surgeons diverged. Surgeon continued, however, to be used as the title for military medical officers until the end of the 19th century, the title of Surgeon General continues to exist for both senior military medical officers and senior government public health officers. In 1950, the Royal College of Surgeons of England in London began to offer surgeons a formal status via RCS membership.
The title Mister became a badge of honour, today, in many Commonwealth countries, a qualified doctor who, after at least four years' training, obtains a surgical qualification is given the honour of being allowed to revert to calling themselves Mr, Mrs or Ms in the course of their professional practice, but this time the meaning is different. It is sometimes assumed that the change of title implies consultant status, but the length of postgraduate medical training outside North America is such that a qualified surgeon may be years away from obtaining such a post: many doctors obtained these qualifications in the senior house officer grade, remained in that grade when they began sub-specialty training; the distinction of Mr is used by surgeons in the Republic of Ireland, some states of Australia, New Zealand, South Africa and some other Commonwealth countries. In many English-speaking countries the military title of surgeon is applied to any medical practitioner, due to the historical evolution of the term.
The US Army Medical Corps retains various surgeon MOS' in the ranks of officer pay grades for military personnel dedicated to performing surgery on wounded soldiers. Some physicians who are general practitioners or specialists in family medicine or emergency medicine may perform limited ranges of minor, common, or emergency surgery. Anesthesia accompanies surgery, anesthesiologists and nurse anesthetists may oversee this aspect of surgery. Surgeon's assistant, surgical nurses, surgical technologists are trained professionals who support surgeons. In the United States, the Department of Labor description of a surgeon is "a physician who treats diseases and deformities by invasive, minimally-invasive, or non-invasive surgical methods, such as using instruments, appliances, or by manual manipulation".

Biblioteca Nacional de España
The Biblioteca Nacional de España is a major public library, the largest in Spain, one of the largest in the world. It is located on the Paseo de Recoletos; the library was founded by King Philip V in 1712 as the Palace Public Library. The Royal Letters Patent that he granted, the predecessor of the current legal deposit requirement, made it mandatory for printers to submit a copy of every book printed in Spain to the library. In 1836, the library's status as Crown property was revoked and ownership was transferred to the Ministry of Governance. At the same time, it was renamed the Biblioteca Nacional. During the 19th century, confiscations and donations enabled the Biblioteca Nacional to acquire the majority of the antique and valuable books that it holds. In 1892 the building was used to host the Historical American Exposition. On March 16, 1896, the Biblioteca Nacional opened to the public in the same building in which it is housed and included a vast Reading Room on the main floor designed to hold 320 readers.
In 1931 the Reading Room was reorganised, providing it with a major collection of reference works, the General Reading Room was created to cater for students and general readers. During the Spanish Civil War close to 500,000 volumes were collected by the Confiscation Committee and stored in the Biblioteca Nacional to safeguard works of art and books held until in religious establishments and private houses. During the 20th century numerous modifications were made to the building to adapt its rooms and repositories to its expanding collections, to the growing volume of material received following the modification to the Legal Deposit requirement in 1958, to the numerous works purchased by the library. Among this building work, some of the most noteworthy changes were the alterations made in 1955 to triple the capacity of the library's repositories, those started in 1986 and completed in 2000, which led to the creation of the new building in Alcalá de Henares and complete remodelling of the building on Paseo de Recoletos, Madrid.
In 1986, when Spain's main bibliographic institutions - the National Newspaper Library, the Spanish Bibliographic Institute and the Centre for Documentary and Bibliographic Treasures - were incorporated into the Biblioteca Nacional, the library was established as the State Repository of Spain's Cultural Memory, making all of Spain's bibliographic output on any media available to the Spanish Library System and national and international researchers and cultural and educational institutions. In 1990 it was made an Autonomous Entity attached to the Ministry of Culture; the Madrid premises are shared with the National Archaeological Museum. The Biblioteca Nacional is Spain's highest library institution and is head of the Spanish Library System; as the country's national library, it is the centre responsible for identifying, preserving and disseminating information about Spain's documentary heritage, it aspires to be an essential point of reference for research into Spanish culture. In accordance with its Articles of Association, passed by Royal Decree 1581/1991 of October 31, 1991, its principal functions are to: Compile and conserve bibliographic archives produced in any language of the Spanish state, or any other language, for the purposes of research and information.
Promote research through the study and reproduction of its bibliographic archive. Disseminate information on Spain's bibliographic output based on the entries received through the legal deposit requirement; the library's collection consists of more than 26,000,000 items, including 15,000,000 books and other printed materials, 4,500,000 graphic materials, 600,000 sound recordings, 510,000 music scores, more than 500,000 microforms, 500,000 maps, 143,000 newspapers and serials, 90,000 audiovisuals, 90,000 electronic documents, 30,000 manuscripts. The current director of the Biblioteca Nacional is Ana Santos Aramburo, appointed in 2013. Former directors include her predecessors Glòria Pérez-Salmerón and Milagros del Corral as well as historian Juan Pablo Fusi and author Rosa Regàs. Given its role as the legal deposit for the whole of Spain, since 1991 it has kept most of the overflowing collection at a secondary site in Alcalá de Henares, near Madrid; the Biblioteca Nacional provides access to its collections through the following library services: Guidance and general information on the institution and other libraries.
Bibliographic information about its collection and those held by other libraries or library systems. Access to its automated catalogue, which contains close to 3,000,000 bibliographic records encompassing all of its collections. Archive consultation in the library's reading rooms. Interlibrary loans. Archive reproduction.

Bulgaria the Republic of Bulgaria, is a country in Southeast Europe. It is bordered by Romania to the north and North Macedonia to the west and Turkey to the south, the Black Sea to the east; the capital and largest city is Sofia. With a territory of 110,994 square kilometres, Bulgaria is Europe's 16th-largest country. One of the earliest societies in the lands of modern-day Bulgaria was the Neolithic Karanovo culture, which dates back to 6,500 BC. In the 6th to 3rd century BC the region was a battleground for Thracians, Persians and ancient Macedonians; the Eastern Roman, or Byzantine, Empire lost some of these territories to an invading Bulgar horde in the late 7th century. The Bulgars founded the First Bulgarian Empire in AD 681, which dominated most of the Balkans and influenced Slavic cultures by developing the Cyrillic script; this state lasted until the early 11th century, when Byzantine emperor Basil II conquered and dismantled it. A successful Bulgarian revolt in 1185 established a Second Bulgarian Empire, which reached its apex under Ivan Asen II.
After numerous exhausting wars and feudal strife, the Second Bulgarian Empire disintegrated in 1396 and its territories fell under Ottoman rule for nearly five centuries. The Russo-Turkish War of 1877–78 resulted in the formation of the current Third Bulgarian State. Many ethnic Bulgarian populations were left outside its borders, which led to several conflicts with its neighbours and an alliance with Germany in both world wars. In 1946 Bulgaria became part of the Soviet-led Eastern Bloc; the ruling Communist Party gave up its monopoly on power after the revolutions of 1989 and allowed multi-party elections. Bulgaria transitioned into a democracy and a market-based economy. Since adopting a democratic constitution in 1991, the sovereign state has been a unitary parliamentary republic with a high degree of political and economic centralisation; the population of seven million lives in Sofia and the capital cities of the 27 provinces, the country has suffered significant demographic decline since the late 1980s.
Bulgaria is a member of the European Union, NATO, the Council of Europe. Its market economy is part of the European Single Market and relies on services, followed by industry—especially machine building and mining—and agriculture. Widespread corruption is a major socioeconomic issue; the name Bulgaria is derived from a tribe of Turkic origin that founded the country. Their name is not understood and difficult to trace back earlier than the 4th century AD, but it is derived from the Proto-Turkic word bulģha and its derivative bulgak; the meaning may be further extended to "rebel", "incite" or "produce a state of disorder", i.e. the "disturbers". Ethnic groups in Inner Asia with phonologically similar names were described in similar terms: during the 4th century, the Buluoji, a component of the "Five Barbarian" groups in Ancient China, were portrayed as both a "mixed race" and "troublemakers". Neanderthal remains dating to around 150,000 years ago, or the Middle Paleolithic, are some of the earliest traces of human activity in the lands of modern Bulgaria.
The Karanovo culture arose circa 6,500 BC and was one of several Neolithic societies in the region that thrived on agriculture. The Copper Age Varna culture is credited with inventing gold metallurgy; the associated Varna Necropolis treasure contains the oldest golden jewellery in the world with an approximate age of over 6,000 years. The treasure has been valuable for understanding social hierarchy and stratification in the earliest European societies; the Thracians, one of the three primary ancestral groups of modern Bulgarians, appeared on the Balkan Peninsula some time before the 12th century BC. The Thracians excelled in metallurgy and gave the Greeks the Orphean and Dionysian cults, but remained tribal and stateless; the Persian Achaemenid Empire conquered most of present-day Bulgaria in the 6th century BC and retained control over the region until 479 BC. The invasion became a catalyst for Thracian unity, the bulk of their tribes united under king Teres to form the Odrysian kingdom in the 470s BC.
It was weakened and vassalized by Philip II of Macedon in 341 BC, attacked by Celts in the 3rd century, became a province of the Roman Empire in AD 45. By the end of the 1st century AD, Roman governance was established over the entire Balkan Peninsula and Christianity began spreading in the region around the 4th century; the Gothic Bible—the first Germanic language book—was created by Gothic bishop Ulfilas in what is today northern Bulgaria around 381. The region came under Byzantine control after the fall of Rome in 476; the Byzantines were engaged in prolonged warfare against Persia and could not defend their Balkan territories from barbarian incursions. This enabled the Slavs to enter the Balkan Peninsula as marauders through an area between the Danube River and the Balkan Mountains known as Moesia; the interior of the peninsula became a country of the South Slavs, who lived under a democracy. The Slavs assimilated the Hellenized and Gothicized Thracians in the rural areas. Not l
Russia the Russian Federation, is a transcontinental country in Eastern Europe and North Asia. At 17,125,200 square kilometres, Russia is by far or by a considerable margin the largest country in the world by area, covering more than one-eighth of the Earth's inhabited land area, the ninth most populous, with about 146.77 million people as of 2019, including Crimea. About 77 % of the population live in the European part of the country. Russia's capital, Moscow, is one of the largest cities in the world and the second largest city in Europe. Extending across the entirety of Northern Asia and much of Eastern Europe, Russia spans eleven time zones and incorporates a wide range of environments and landforms. From northwest to southeast, Russia shares land borders with Norway, Estonia, Latvia and Poland, Ukraine, Azerbaijan, China and North Korea, it shares maritime borders with Japan by the Sea of Okhotsk and the U. S. state of Alaska across the Bering Strait. However, Russia recognises two more countries that border it, Abkhazia and South Ossetia, both of which are internationally recognized as parts of Georgia.
The East Slavs emerged as a recognizable group in Europe between the 3rd and 8th centuries AD. Founded and ruled by a Varangian warrior elite and their descendants, the medieval state of Rus arose in the 9th century. In 988 it adopted Orthodox Christianity from the Byzantine Empire, beginning the synthesis of Byzantine and Slavic cultures that defined Russian culture for the next millennium. Rus' disintegrated into a number of smaller states; the Grand Duchy of Moscow reunified the surrounding Russian principalities and achieved independence from the Golden Horde. By the 18th century, the nation had expanded through conquest and exploration to become the Russian Empire, the third largest empire in history, stretching from Poland on the west to Alaska on the east. Following the Russian Revolution, the Russian Soviet Federative Socialist Republic became the largest and leading constituent of the Union of Soviet Socialist Republics, the world's first constitutionally socialist state; the Soviet Union played a decisive role in the Allied victory in World War II, emerged as a recognized superpower and rival to the United States during the Cold War.
The Soviet era saw some of the most significant technological achievements of the 20th century, including the world's first human-made satellite and the launching of the first humans in space. By the end of 1990, the Soviet Union had the world's second largest economy, largest standing military in the world and the largest stockpile of weapons of mass destruction. Following the dissolution of the Soviet Union in 1991, twelve independent republics emerged from the USSR: Russia, Belarus, Uzbekistan, Azerbaijan, Kyrgyzstan, Tajikistan and the Baltic states regained independence: Estonia, Lithuania, it is governed as a federal semi-presidential republic. Russia's economy ranks as the twelfth largest by nominal GDP and sixth largest by purchasing power parity in 2018. Russia's extensive mineral and energy resources are the largest such reserves in the world, making it one of the leading producers of oil and natural gas globally; the country is one of the five recognized nuclear weapons states and possesses the largest stockpile of weapons of mass destruction.
Russia is a great power as well as a regional power and has been characterised as a potential superpower. It is a permanent member of the United Nations Security Council and an active global partner of ASEAN, as well as a member of the Shanghai Cooperation Organisation, the G20, the Council of Europe, the Asia-Pacific Economic Cooperation, the Organization for Security and Co-operation in Europe, the World Trade Organization, as well as being the leading member of the Commonwealth of Independent States, the Collective Security Treaty Organization and one of the five members of the Eurasian Economic Union, along with Armenia, Belarus and Kyrgyzstan; the name Russia is derived from Rus', a medieval state populated by the East Slavs. However, this proper name became more prominent in the history, the country was called by its inhabitants "Русская Земля", which can be translated as "Russian Land" or "Land of Rus'". In order to distinguish this state from other states derived from it, it is denoted as Kievan Rus' by modern historiography.
The name Rus itself comes from the early medieval Rus' people, Swedish merchants and warriors who relocated from across the Baltic Sea and founded a state centered on Novgorod that became Kievan Rus. An old Latin version of the name Rus' was Ruthenia applied to the western and southern regions of Rus' that were adjacent to Catholic Europe; the current name of the country, Россия, comes from the Byzantine Greek designation of the Rus', Ρωσσία Rossía—spelled Ρωσία in Modern Greek. The standard way to refer to citizens of Russia is rossiyane in Russian. There are two Russian words which are commonly
Royal Library of the Netherlands
The Royal Library of the Netherlands is based in The Hague and was founded in 1798. The mission of the Royal Library of the Netherlands, as presented on the library's web site, is to provide "access to the knowledge and culture of the past and the present by providing high-quality services for research and cultural experience"; the initiative to found a national library was proposed by representative Albert Jan Verbeek on August 17 1798. The collection would be based on the confiscated book collection of William V; the library was founded as the Nationale Bibliotheek on November 8 of the same year, after a committee of representatives had advised the creation of a national library on the same day. The National Library was only open to members of the Representative Body. King Louis Bonaparte gave the national library its name of the Royal Library in 1806. Napoleon Bonaparte transferred the Royal Library to The Hague as property, while allowing the Imperial Library in Paris to expropriate publications from the Royal Library.
In 1815 King William I of the Netherlands confirmed the name of'Royal Library' by royal resolution. It has been known as the National Library of the Netherlands since 1982, when it opened new quarters; the institution became independent of the state in 1996, although it is financed by the Department of Education and Science. In 2004, the National Library of the Netherlands contained 3,300,000 items, equivalent to 67 kilometers of bookshelves. Most items in the collection are books. There are pieces of "grey literature", where the author, publisher, or date may not be apparent but the document has cultural or intellectual significance; the collection contains the entire literature of the Netherlands, from medieval manuscripts to modern scientific publications. For a publication to be accepted, it must be from a registered Dutch publisher; the collection is accessible for members. Any person aged 16 years or older can become a member. One day passes are available. Requests for material take 30 minutes.

Bulgarians are a South Slavic ethnic group who are native to Bulgaria and its neighboring regions. Bulgarians derive their ethnonym from the Bulgars, their name is not understood and difficult to trace back earlier than the 4th century AD, but it is derived from the Proto-Turkic word bulģha and its derivative bulgak. Alternate etymologies include derivation from a compound of Proto-Turkic bel and gur, a proposed division within the Utigurs or Onogurs. According to the Art.25 of Constitution of Bulgaria, a Bulgarian citizen shall be anyone born to at least one parent holding a Bulgarian citizenship, or born on the territory of the Republic of Bulgaria, should they not be entitled to any other citizenship by virtue of origin. Bulgarian citizenship shall further be acquirable through naturalization. About 77% of Bulgaria's population identified themselves as Bulgarians in 2011 Bulgarian census; the population of Bulgaria descend from peoples with different numbers. They became assimilated by the Slavic settlers in the First Bulgarian Empire.
Two of the non-Slavic nations maintain a legacy among modern-day Bulgarians: the Thracians, from whom cultural and ethnic elements were taken. From the indigenous Thracian people certain cultural and ethnic elements were taken. Other pre-Slavic Indo-European peoples, including Dacians, Goths, Ancient Greeks, Sarmatians and Illyrians settled into the Bulgarian land; the Thracian language has been described as a southern Baltic language. It was still spoken in the 6th century becoming extinct afterwards, but that in a period the Bulgarians replaced long-established Greek/Latin toponyms with Thracian toponyms might suggest that Thracian had not been obliterated then; some pre-Slavic linguistic and cultural traces might have been preserved in modern Bulgarians. Scythia Minor and Moesia Inferior appear to have been Romanized, although the region became a focus of barbarian re-settlements during the 4th and early 5th centuries AD, before a further "Romanization" episode during the early 6th century.
According to archeological evidence from the late periods of Roman rule, the Romans did not decrease the number of Thracians in major cities. By the 4th century the major city of Serdica had predominantly Thracian populace based on epigraphic evidence, which shows prevailing Latino-Thracian given names, but thereafter the names were replaced by Christian ones; the Early Slavs emerged from their original homeland in the early 6th century, spread to most of the eastern Central Europe, Eastern Europe and the Balkans, thus forming three main branches: the West Slavs in eastern Central Europe, the East Slavs in Eastern Europe, the South Slavs in Southeastern Europe. The latter inflicted total linguistic replacement of Thracian, if the Thracians had not been Romanized or Hellenized. Most scholars accept that they began large-scale settling of the Balkans in the 580s based on the statement of the 6th century historian Menander speaking of 100,000 Slavs in Thrace and consecutive attacks of Greece in 582.
They continued coming to the Balkans in many waves, but leaving, most notably Justinian II settled as many as 30,000 Slavs from Thrace in Asia Minor. The Byzantines grouped the numerous Slavic tribes into two groups: the Sklavenoi and Antes; some Bulgarian scholars suggest. The Bulgars are first mentioned in the 4th century in the vicinity of the North Caucasian steppe. Scholars suggest that the ultimate origins of the Bulgar is Turkic and can be traced to the Central Asian nomadic confederations as part of loosely related Oghuric tribes which spanned from the Pontic steppe to central Asia. However, any direct connection between the Bulgars and postulated Asian counterparts rest on little more than speculative and "contorted etymologies"; some Bulgarian historians question the identification of the Bulgars as a Turkic tribe and suggest an Iranian origin. In the 670s, some Bulgar tribes, the Danube Bulgars led by Asparukh and the Macedonian Bulgars, led by Kouber, crossed the Danube river and settled in the Balkans with a single migration wave, the former of which Michael the Syrian described as numbering 10,000.
The Bulgars are not thought to have been numerous, becoming a ruling elite in the areas they controlled. However, according to Steven Runciman a tribe, able to defeat a Byzantine army, must have been of considerable dimensions. Asparukh's Bulgars made a tribal union with the Severians and the "Seven clans", who were re-settled to protect the flanks of the Bulgar settlements in Scythia Minor, as the capital Pliska was built on the site of a former Slavic settlement. During the Early Byzantine Era, the Roman provincials in Scythia Minor and Moesia Secunda were engaged in economic and social exchange with the'barbarians' north of the Danube; this might have facilitated their eventual Slavonization, although the majority of the population appears to have been withdrawn to the hinterland of Constantinople or Asia Minor prior to any permanent Slavic and Bulgar settlement south of the Danube. The major port towns in Pontic Bulgaria remained Byzantine Greek in their outlook; the large scale population transfers and territorial expansions during the 8th and 9th century, additionally increased the number of the Slavs and Byzantine Christians within the state, making the Bulgars quite a
National Library of the Czech Republic
The National Library of the Czech Republic is the central library of the Czech Republic. It is directed by the Ministry of Culture; the library's main building is located in the historical Clementinum building in Prague, where half of its books are kept. The other half of the collection is stored in the district of Hostivař; the National Library is the biggest library in the Czech Republic, in its funds there are around 6 million documents. The library has around 60,000 registered readers; as well as Czech texts, the library stores older material from Turkey and India. The library houses books for Charles University in Prague; the library won international recognition in 2005 as it received the inaugural Jikji Prize from UNESCO via the Memory of the World Programme for its efforts in digitising old texts. The project, which commenced in 1992, involved the digitisation of 1,700 documents in its first 13 years; the most precious medieval manuscripts preserved in the National Library are the Codex Vyssegradensis and the Passional of Abbes Kunigunde.
In 2006 the Czech parliament approved funding for the construction of a new library building on Letna plain, between Hradčanská metro station and Sparta Prague's football ground, Letná stadium. In March 2007, following a request for tender, Czech architect Jan Kaplický was selected by a jury to undertake the project, with a projected completion date of 2011. In 2007 the project was delayed following objections regarding its proposed location from government officials including Prague Mayor Pavel Bém and President Václav Klaus. Plans for the building had still not been decided in February 2008, with the matter being referred to the Office for the Protection of Competition in order to determine if the tender had been won fairly. In 2008, Minister of Culture Václav Jehlička announced the end of the project, following a ruling from the European Commission that the tender process had not been carried out legally; the library was affected by the 2002 European floods, with some documents moved to upper levels to avoid the excess water.
Over 4,000 books were removed from the library in July 2011 following flooding in parts of the main building. There was a fire at the library in December 2012. List of national and state libraries Official website
