Oxytropis Urumovii
''Oxytropis urumovii'' is a species of flowering plant in the Fabaceae, legume family endemic to Bulgaria, where it is restricted to the Pirin mountain range. There, it is found at altitudes of 2,500–2,800 m in the cirques of Malkia and Golemiya Kazan and the summits of Vihren (2,914 m), Banski Suhodol (2,884 m), Banski Suhodol (2,728 m) and Kamenititsa (2,726 m) in the protected areas of Pirin National Park and Bayuvi Dupki–Dzhindzhiritsa Nature Reserve. ''Oxytropis urumovii'' is distinctive compared to the other Balkans, Balkan species of ''Oxytropis'', with a semi-bilocular or almost completely bilocular legume. The plant, including the fruit, is densely covered with 2–3 mm patent whitish hairs. Amongst the European species of Oxytropis, ''Oxytropis urumovii'' is diagnosed by being acaulescent, having leaves with about eight pairs of leaflets, calyx-teeth which are much shorter than the tube, yellowish flowers and an ovoid semi-bilocular legu ...

Sándor Jávorka
Sándor Jávorka (12 March 1883 - 28 September 1961) was a Hungarian botanist. His birthplace was Hegybánya, then in the Kingdom of Hungary, now in Slovakia and now called Štiavnické Bane. He died in Budapest. Occasionally he has been referred to as Alexander Jávorka; the Hungarian style of his name is Jávorka Sándor. Life and work After attending school in Selmecbánya (now called Banská Štiavnica), Sándor Jávorka studied at the University of Budapest and graduated in 1906 with a thesis on the genus ''Onosma''. Since 1905 he was employed in the Department of Botany of the Hungarian National Museum, where he worked until 1940, latterly as its director. Even after retirement, he remained there still active. In 1939 he became a professor at the University of Budapest. In 1936 he became a corresponding member of the Hungarian Academy of Sciences, and seven years later a permanent member. In 1952 he was awarded the Kossuth Prize. The focus of Jávorka's scientific work was pla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Onobrychis Scardica
__NOTOC__ ''Onobrychis'', the sainfoins, are a genus of Eurasian perennial herbaceous plants of the legume family (Fabaceae). Including doubtfully distinct species and provisionally accepted taxa, about 150 species are presently known. The Flora Europaea lists 23 species of ''Onobrychis''; the main centre of diversity extends from Central Asia to Iran, with 56 species – 27 of which are endemic – in the latter country alone. '' O. viciifolia'' is naturalized throughout many countries in Europe and North America grasslands on calcareous soils. Description, ecology and uses Sainfoins are mostly subtropical plants, but their range extends throughout Europe as far north as southern Sweden. These plants grow on grassland, agricultural land and wasteland. The leaves are pinnate, alternate, with 6 to 14 pairs of oblong to linear leaflets. Sainfoins have pale pink flowers, typically blooming between June and September and pollinated by honey bees and solitary bees. The ...

Plants Described In 1920
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have los ...

Sofia
Sofia ( ; bg, София, Sofiya, ) is the capital and largest city of Bulgaria. It is situated in the Sofia Valley at the foot of the Vitosha mountain in the western parts of the country. The city is built west of the Iskar river, and has many mineral springs, such as the Sofia Central Mineral Baths. It has a humid continental climate. Being in the centre of the Balkans, it is midway between the Black Sea and the Adriatic Sea, and closest to the Aegean Sea. Known as Serdica in Antiquity and Sredets in the Middle Ages, Sofia has been an area of human habitation since at least 7000 BC. The recorded history of the city begins with the attestation of the conquest of Serdica by the Roman Republic in 29 BC from the Celtic tribe Serdi. During the decline of the Roman Empire, the city was raided by Huns, Visigoths, Avars and Slavs. In 809, Serdica was incorporated into the Bulgarian Empire by Khan Krum and became known as Sredets. In 1018, the Byzantines ended Bulgarian rule ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bulgarian Academy Of Sciences
The Bulgarian Academy of Sciences (abbreviated BAS; bg, Българска академия на науките, ''Balgarska akademiya na naukite'', abbreviated ''БАН'') is the National Academy of Bulgaria, established in 1869. The Academy, with headquarters in Sofia, is autonomous and consists of a Society of Academicians, Correspondent Members and Foreign Members. It publishes and circulates different scientific works, encyclopaedias, dictionaries and journals, and runs its own publishing house. The activities are distributed in three main branches: ''Natural, mathematical and engineering sciences''; ''Biological, medical and agrarian sciences'' and ''Social sciences, humanities and art''. They are structured in 42 independent scientific institutes, and a dozen of laboratories and other sections. Julian Revalski has been the president of the BAS since 2016. As of 2021, its budget was 117,8 million leva (€60,2 million). History As Bulgaria was part of the Ottoman E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ivan Urumov
Ivan () is a Slavic male given name, connected with the variant of the Greek name (English: John) from Hebrew meaning 'God is gracious'. It is associated worldwide with Slavic countries. The earliest person known to bear the name was Bulgarian tsar Ivan Vladislav. It is very popular in Russia, Ukraine, Croatia, Serbia, Bosnia and Herzegovina, Slovenia, Bulgaria, Belarus, North Macedonia, and Montenegro and has also become more popular in Romance-speaking countries since the 20th century. Etymology Ivan is the common Slavic Latin spelling, while Cyrillic spelling is two-fold: in Bulgarian, Russian, Macedonian, Serbian and Montenegrin it is Иван, while in Belarusian and Ukrainian it is Іван. The Old Church Slavonic (or Old Cyrillic) spelling is . It is the Slavic relative of the Latin name , corresponding to English '' John''.

Centaurea Achtarovii
''Centaurea'' () is a genus of over 700 species of herbaceous thistle-like flowering plants in the family Asteraceae. Members of the genus are found only north of the equator, mostly in the Eastern Hemisphere; the Middle East and surrounding regions are particularly species-rich. In the western United States, yellow starthistles are an invasive species. Around the year 1850, seeds from the plant had arrived to the state of California. It is believed that those seeds came from South America. Common names Common names for this genus are centaury, centory, starthistles, knapweeds, centaureas and the more ambiguous "bluets"; a vernacular name used for these plants in parts of England is "loggerheads" ( common knapweed). The ''Plectocephalus'' group – possibly a distinct genus – is known as basketflowers. "Cornflower" is used for a few species, but that term more often specifically means either '' C. cyanus'' (the annual cornflower) or '' Centaurea montana'' (the perennial ...

Thymus Perinicus
The thymus is a specialized primary lymphoid organ of the immune system. Within the thymus, thymus cell lymphocytes or ''T cells'' mature. T cells are critical to the adaptive immune system, where the body adapts to specific foreign invaders. The thymus is located in the upper front part of the chest, in the anterior superior mediastinum, behind the sternum, and in front of the heart. It is made up of two lobes, each consisting of a central medulla and an outer cortex, surrounded by a capsule. The thymus is made up of immature T cells called thymocytes, as well as lining cells called epithelial cells which help the thymocytes develop. T cells that successfully develop react appropriately with MHC immune receptors of the body (called ''positive selection'') and not against proteins of the body (called ''negative selection''). The thymus is largest and most active during the neonatal and pre-adolescent periods. By the early teens, the thymus begins to decrease in size and ac ...
