Candidate of SciencesA Candidate of Sciences (кандидат наук) is the first of two doctoral level scientific degrees in Russia and the Commonwealth of Independent States. It is formally classified as UNESCO's ISCED level 8, "doctoral or equivalent." It may be recognized as a Doctor of Philosophy, usually in natural sciences, by scientific institutions in other countries. Former Soviet countries also have a more advanced degree, Doctor of Sciences.
Doctor of SciencesDoctor of Sciences (доктор наук, abbreviated д-р наук or д. н.; доктор наук; доктор на науките; доктар навук) is a higher doctoral degree in the Russian Empire, Soviet Union and many post-Soviet countries, which may be earned after the Candidate of Sciences. The "Doctor of Sciences" degree was introduced in the Russian Empire in 1819 and abolished in 1917. Later it was revived in the USSR on January 13, 1934, by a decision of the Council of People's Commissars of the USSR.
X-ray tubeAn X-ray tube is a vacuum tube that converts electrical input power into X-rays. The availability of this controllable source of X-rays created the field of radiography, the imaging of partly opaque objects with penetrating radiation. In contrast to other sources of ionizing radiation, X-rays are only produced as long as the X-ray tube is energized. X-ray tubes are also used in CT scanners, airport luggage scanners, X-ray crystallography, material and structure analysis, and for industrial inspection.
Sutton HooSutton Hoo is the site of two early medieval cemeteries dating from the 6th to 7th centuries near the English town of Woodbridge. Archaeologists have been excavating the area since 1938, when a previously undisturbed ship burial containing a wealth of Anglo-Saxon artefacts was discovered. The site is important in establishing the history of the Anglo-Saxon kingdom of East Anglia as well as illuminating the Anglo-Saxons during a period which lacks historical documentation.
Korean mixed scriptKorean mixed script () is a form of writing the Korean language that uses a mixture of the Korean alphabet or Hangul () and Hanja (, ), the Korean name for Chinese characters. The distribution on how to write words usually follows that all native Korean words, including suffixes, particles, and honorific markers are generally written in hangul and never in hanja. Sino-Korean vocabulary or hanja-eo (), either words borrowed from Chinese or created from Sino-Korean roots, were generally always written in hanja, although very rare or complex characters were often substituted with hangul.
Sutton Hoo helmetThe Sutton Hoo helmet is a decorated Anglo-Saxon helmet found during a 1939 excavation of the Sutton Hoo ship-burial. It was buried around the years 620–625 CE and is widely associated with an Anglo-Saxon leader, King Rædwald of East Anglia; its elaborate decoration may have given it a secondary function akin to a crown. The helmet was both a functional piece of armour that would have offered considerable protection if ever used in warfare, and a decorative, prestigious piece of extravagant metalwork.
Yo (Cyrillic)Yo, Jo or Io (Ё ё; italics: Ё ё; jɵ) is a letter of the Cyrillic script. In Unicode, the letter is named CYRILLIC CAPITAL/SMALL LETTER IO. In English, the letter Yo is romanized using the Latin ë (according to the ALA–LC and British Standards), ë (yë word-initially) (BGN/PCGN) or yo/jo (orthographic transcription) for Russian, and as i͡o (ALA–LC), yo (BGN/PCGN), or ë (BSI) for Belarusian. In international systems, Yo is romanized as ë (ISO 9). It was derived from the Cyrillic letter Ye (Е е).
Nail diseaseA nail disease or onychosis is a disease or deformity of the nail. Although the nail is a structure produced by the skin and is a skin appendage, nail diseases have a distinct classification as they have their own signs and symptoms which may relate to other medical conditions. Some nail conditions that show signs of infection or inflammation may require medical assistance. Nail diseases, also known as onychopathies or nail disorders, refer to conditions that affect the health, appearance, and function of the nails.
Bounded variationIn mathematical analysis, a function of bounded variation, also known as BV function, is a real-valued function whose total variation is bounded (finite): the graph of a function having this property is well behaved in a precise sense. For a continuous function of a single variable, being of bounded variation means that the distance along the direction of the y-axis, neglecting the contribution of motion along x-axis, traveled by a point moving along the graph has a finite value.
Subject–object–verb word orderIn linguistic typology, a subject–object–verb (SOV) language is one in which the subject, object, and verb of a sentence always or usually appear in that order. If English were SOV, "Sam beer drank" would be an ordinary sentence, as opposed to the actual Standard English "Sam drank beer" which is subject–verb–object (SVO). The term is often loosely used for ergative languages like Adyghe and Basque that really have agents instead of subjects.
Korean languageKorean (South Korean: , hangugeo; North Korean: , chosŏnmal) is the native language for about 80 million people, mostly of Korean descent. It is the official and national language of both North Korea and South Korea (geographically Korea). The two countries have established standardized norms for Korean, and the differences between them are similar to those between Standard Chinese in mainland China and Taiwan, but political conflicts between the two countries have highlighted the differences between them.
Karl Philipp von WredeKarl (or Carl) Philipp Josef, Prince von Wrede (ˈvʁeːdə; 29 April 1767 - 12 December 1838) was a Bavarian field marshal. He was an ally of Napoleonic France until he negotiated the Treaty of Ried with Austria in 1813. Thereafter Bavaria joined the coalition.
