Cinchonine
Cinchonine is an alkaloid found in ''Cinchona officinalis''. It is used in asymmetric synthesis in organic chemistry. It is a stereoisomer and pseudo-enantiomer of cinchonidine. It is structurally similar to quinine, an antimalarial drug. It is a GLP-1 receptor agonist and therefore has potential as a possible treatment for obesity, type 2 diabetes, and non-alcoholic fatty liver disease.

Edward Bransfield
Edward Bransfield ( – 31 October 1852) was a Royal Navy officer who served as a master on several ships, after being impressed into service in Ireland at the age of 18. He is noted for his participation in several explorations of parts of Antarctica, including a sighting of the Trinity Peninsula in January 1820. Early life Edward Bransfield was born in Ballinacurra, County Cork . While little is known of Edward's family or early life, the Bransfields are thought to have been a well-known and respected Catholic family.Michael Smith, ''Great Endeavour: Ireland's Antarctic Explorers'', Dublin: The Collins Press, 2010, p. 10. They may have had enough money to pay for Edward's education, but because of the Penal Laws, it is more likely that he attended a local hedge school. On 2 June 1803, Bransfield, then eighteen years old, was removed by an press-gang from his father's fishing boat and impressed into the Royal Navy. He began as an ordinary seaman on the 110-gun first-ra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Navy
The Royal Navy (RN) is the naval warfare force of the United Kingdom. It is a component of His Majesty's Naval Service, and its officers hold their commissions from the King of the United Kingdom, King. Although warships were used by Kingdom of England, English and Kingdom of Scotland, Scottish kings from the early Middle Ages, medieval period, the first major maritime engagements were fought in the Hundred Years' War against Kingdom of France, France. The modern Royal Navy traces its origins to the English Navy of the early 16th century; the oldest of the British Armed Forces, UK's armed services, it is consequently known as the Senior Service. From the early 18th century until the World War II, Second World War, it was the world's most powerful navy. The Royal Navy played a key part in establishing and defending the British Empire, and four Imperial fortress colonies and a string of imperial bases and coaling stations secured the Royal Navy's ability to assert naval superior ...

Irish People
The Irish ( or ''Na hÉireannaigh'') are an ethnic group and nation native to the island of Ireland, who share a common ancestry, history and Culture of Ireland, culture. There have been humans in Ireland for about 33,000 years, and it has been continually inhabited for more than 10,000 years (see Prehistoric Ireland). For most of Ireland's recorded history, the Irish have been primarily a Gaels, Gaelic people (see Gaelic Ireland). From the 9th century, small numbers of Vikings settled in Ireland, becoming the Norse-Gaels. Anglo-Normans also Norman invasion of Ireland, conquered parts of Ireland in the 12th century, while Kingdom of England, England's 16th/17th century Tudor conquest of Ireland, conquest and Plantations of Ireland, colonisation of Ireland brought many English people, English and Scottish Lowlands, Lowland Scottish people, Scots to parts of the island, especially the north. Today, Ireland is made up of the Republic of Ireland (officially called Republic of Irela ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fabian Gottlieb Von Bellingshausen
Faddey Faddeyevich Bellingshausen or Fabian Gottlieb Benjamin von Bellingshausen ( – ) was a Russian cartographer, explorer, and naval officer of Baltic German descent, who attained the rank of admiral. He participated in the first Russian circumnavigation of the globe, and subsequently became a leader of another circumnavigation expedition that discovered the continent of Antarctica. Like Otto von Kotzebue and Adam Johann von Krusenstern, Bellingshausen belonged to a cohort of prominent Baltic German navigators which helped Russia launch its naval expeditions. Bellingshausen was born on the island of Saaremaa ( Ösel), to the . He started his service in the Russian Baltic Fleet, and after distinguishing himself joined the first Russian circumnavigation of the Earth in 1803–1806, serving on the merchant ship ''Nadezhda'' under the captaincy of Adam Johann von Krusenstern.

Imperial Russian Navy
The Imperial Russian Navy () operated as the navy of the Russian Tsardom and later the Russian Empire from 1696 to 1917. Formally established in 1696, it lasted until being dissolved in the wake of the February Revolution and the declaration of the Russian Republic in 1917. It developed from a smaller force that had existed prior to Tsar Peter the Great's founding of the modern Russian navy during the Azov campaigns (1695–1696), Second Azov campaign in 1696, and expanded in the second half of the 18th century before reaching its peak strength by the early part of the 19th century, behind only the British and French fleets in terms of size. The Imperial Navy drew its officers from the aristocracy of the Empire, who belonged to the state Russian Orthodox Church. Young aristocrats began to be trained for leadership at a national naval boarding school, the Naval Cadet Corps (Russia), Naval Cadet Corps. From 1818 on, only officers of the Imperial Russian Navy were appointed to the p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antarctic Ice Sheet
The Antarctic ice sheet is a continental glacier covering 98% of the Antarctic continent, with an area of and an average thickness of over . It is the largest of Earth's two current ice sheets, containing of ice, which is equivalent to 61% of all fresh water on Earth. Its surface is nearly continuous, and the only ice-free areas on the continent are the dry valleys, nunataks of the Antarctic mountain ranges, and sparse coastal bedrock. However, it is often subdivided into the East Antarctic ice sheet (EAIS), West Antarctic ice sheet (WAIS), and Antarctic Peninsula (AP), due to the large differences in topography, ice flow, and glacier mass balance between the three regions. Because the East Antarctic ice sheet is over 10 times larger than the West Antarctic ice sheet and located at a higher elevation, it is less vulnerable to climate change than the WAIS. In the 20th century, EAIS had been one of the only places on Earth which displayed limited cooling instead of warming, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Old Style And New Style Dates
Old Style (O.S.) and New Style (N.S.) indicate dating systems before and after a calendar change, respectively. Usually, they refer to the change from the Julian calendar to the Gregorian calendar as enacted in various Europe, European countries between 1582 and 1923. In England, Wales, Ireland and British America, Britain's American colonies, there were two calendar changes, both in 1752. The first adjusted the start of a new year from 25 March (Lady Day, the Feast of the Annunciation) to 1 January, a change which Scotland had made in 1600. The second discarded the Julian calendar in favour of the Gregorian calendar, skipping 11 days in the month of September to do so.. "Before 1752, parish registers, in addition to a new year heading after 24th March showing, for example '1733', had another heading at the end of the following December indicating '1733/4'. This showed where the Historical Year 1734 started even though the Civil Year 1733 continued until 24th March. ... We as h ...

Friedrich Accum
Friedrich Christian Accum or Frederick Accum (29 March 1769 – 28 June 1838) was a German chemist, whose most important achievements included advances in the field of gas lighting, efforts to keep processed foods free from dangerous additives, and the promotion of interest in the science of chemistry to the general populace. From 1793 to 1821 Accum lived in London. Following an apprenticeship as an apothecary, he opened his own commercial laboratory enterprise. His business manufactured and sold a variety of chemicals and laboratory equipment. Accum, himself, gave fee-based public lectures in practical chemistry and collaborated with research efforts at numerous other institutes of science. Intrigued by the work of Frederick Winsor, who had been championing the introduction of gas lighting in London, Accum too, became fascinated by this innovation. At the request of the Gas Light and Coke Company, he carried out many experiments in this novel field of inquiry. After a time of cl ...

Solanum Nigrum
''Solanum nigrum'', the European black nightshade or simply black nightshade or blackberry nightshade, is a species of flowering plant in the family Solanaceae, native to Eurasia and introduced in the Americas, Australasia, and South Africa. Ripe berries and cooked leaves of edible strains are used as food in some locales, and plant parts are used as a traditional medicine. Some other species may also be referred to as "black nightshade". ''Solanum nigrum'' has been recorded from deposits of the Paleolithic and Mesolithic era of ancient Great Britain, Britain and it is suggested by the botanist and ecologist Edward James Salisbury, Edward Salisbury that it was part of the native flora there before Neolithic agriculture emerged. The species was mentioned by Pliny the Elder in the first century AD and by the great herbalists, including Dioscorides. In 1753, Carl Linnaeus described six varieties of ''Solanum nigrum'' in ''Species Plantarum''. Description Black nightshade is a comm ...
