Macleod Point
Macleod Point () is a point forming the southeastern tip of Liège Island, in the Palmer Archipelago, Antarctica. It was shown on an Argentine government chart in 1957, but not named. The point was photographed from the air by Hunting Aerosurveys Ltd in 1956–57, and mapped from these photos by the Falkland Islands Dependencies Survey in 1959. It was named by the UK Antarctic Place-Names Committee for John Macleod, a Scottish physiologist who was one of the discoverers of insulin Insulin (, from Latin ''insula'', 'island') is a peptide hormone produced by beta cells of the pancreatic islets encoded in humans by the ''INS'' gene. It is considered to be the main anabolic hormone of the body. It regulates the metabolism o ... in 1922. References Headlands of the Palmer Archipelago Liège Island {{LiegeIsland-geo-stub ...

Liège Island
Liège Island (in English also Liege Island) is an island, long and wide, lying immediately northeast of Brabant Island in the Palmer Archipelago, and separated from Hoseason Island and Christiania Islands to the northeast by Croker Passage. Its interior is occupied by Brugmann Mountains. Liège Island is located at . British mapping in 1978 and 1980. The island was charted by the Belgian Antarctic Expedition (1897–1899) under Adrien de Gerlache, who named it for the province of Liège, Belgium. SCAR .

Palmer Archipelago
Palmer Archipelago, also known as Antarctic Archipelago, Archipiélago Palmer, Antarktiske Arkipel or Palmer Inseln, is a group of islands off the northwestern coast of the Antarctic Peninsula. It extends from Tower Island in the north to Anvers Island in the south. It is separated by the Gerlache and Bismarck straits from the Antarctic Peninsula and Wilhelm Archipelago, respectively. Palmer Archipelago is located at . History Adrien de Gerlache, leader of the Belgian Antarctic Expedition (1897–1899), discovered the archipelago in 1898. He named it Archipelago Palmer for American Captain Nathaniel Palmer, who navigated these waters in 1820.

Hunting Aerosurveys Ltd
Hunting Aerosurveys Ltd was a British aerial photography company founded by Percy Hunting in 1944. Its operations became more diversified under the name Hunting Surveys. History The firm incorporated Aerofilms Ltd and the Aircraft Operating Company. In 1947 it was using three types of aircraft: Austers, a Percival Proctor and a de Havilland Dragon Rapide and planned to acquire one or more Percival Mergansers. The company had contracts for work surveying for tin mining in Nigeria; oil in Arabia, Venezuela and Colombia; timber in Ontario; and mapping in Australia & Hong Kong (in 1963). Between 1957 and 1964, Hunting operated a specially converted Auster Autocar for smaller scale aerial survey work. In 1960 the firm was merged with Hunting Geophysics Ltd to form Hunting Surveys Ltd. Threatened with closure in the mid-1980s, it was merged with sister company Hunting Aerofilms Ltd to become simply Aerofilms Ltd in 1987. The new company was able to provide state-of-the-art ...

Falkland Islands Dependencies Survey
The British Antarctic Survey (BAS) is the United Kingdom's national polar research institute. It has a dual purpose, to conduct polar science, enabling better understanding of global issues, and to provide an active presence in the Antarctic on behalf of the UK. It is part of the Natural Environment Research Council (NERC). With over 400 staff, BAS takes an active role in Antarctic affairs, operating five research stations, one ship and five aircraft in both polar regions, as well as addressing key global and regional issues. This involves joint research projects with over 40 UK universities and more than 120 national and international collaborations. Having taken shape from activities during World War II, it was known as the Falkland Islands Dependencies Survey until 1962. History Operation Tabarin was a small British expedition in 1943 to establish permanently occupied bases in the Antarctic. It was a joint undertaking by the British Admiralty, Admiralty and the Secretary of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
UK Antarctic Place-Names Committee
The UK Antarctic Place-Names Committee (or UK-APC) is a United Kingdom government committee, part of the Foreign and Commonwealth Office, responsible for recommending names of geographical locations within the British Antarctic Territory (BAT) and the South Georgia and the South Sandwich Islands (SGSSI). Such names are formally approved by the Commissioners of the BAT and SGSSI respectively, and published in the BAT Gazetteer and the SGSSI Gazetteer maintained by the Committee. The BAT names are also published in the international Composite Gazetteer of Antarctica maintained by SCAR. The Committee may also consider proposals for new place names for geographical features in areas of Antarctica outside BAT and SGSSI, which are referred to other Antarctic place-naming authorities, or decided by the Committee itself if situated in the unclaimed sector of Antarctica. Names attributed by the committee * Anvil Crag, named for descriptive features *Anckorn Nunataks, named after J. F. Anc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Macleod (physiologist)
John James Rickard Macleod (6 September 1876 – 16 March 1935) was a Scottish biochemist and physiologist. He devoted his career to diverse topics in physiology and biochemistry, but was chiefly interested in carbohydrate metabolism. He is noted for his role in the discovery and isolation of insulin during his tenure as a lecturer at the University of Toronto, for which he and Frederick Banting received the 1923 Nobel prize in Physiology or Medicine. Awarding the prize to Macleod was controversial at the time, because according to Banting's version of events, Macleod's role in the discovery was negligible. It was not until decades after the events that an independent review acknowledged a far greater role than was attributed to him at first. Biography Macleod was born in Clunie, near Dunkeld in Perthshire. Soon after he was born, his father Robert Macleod, a clergyman, was transferred to Aberdeen, where John attended Aberdeen Grammar School and enrolled in the study of ...

Insulin
Insulin (, from Latin ''insula'', 'island') is a peptide hormone produced by beta cells of the pancreatic islets encoded in humans by the ''INS'' gene. It is considered to be the main anabolic hormone of the body. It regulates the metabolism of carbohydrates, fats and protein by promoting the absorption of glucose from the blood into liver, fat and skeletal muscle cells. In these tissues the absorbed glucose is converted into either glycogen via glycogenesis or fats ( triglycerides) via lipogenesis, or, in the case of the liver, into both. Glucose production and secretion by the liver is strongly inhibited by high concentrations of insulin in the blood. Circulating insulin also affects the synthesis of proteins in a wide variety of tissues. It is therefore an anabolic hormone, promoting the conversion of small molecules in the blood into large molecules inside the cells. Low insulin levels in the blood have the opposite effect by promoting widespread catabolism, espe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Headlands Of The Palmer Archipelago
A headland, also known as a head, is a coastal landform, a point of land usually high and often with a sheer drop, that extends into a body of water. It is a type of promontory. A headland of considerable size often is called a cape.Whittow, John (1984). ''Dictionary of Physical Geography''. London: Penguin, 1984, pp. 80, 246. . Headlands are characterised by high, breaking waves, rocky shores, intense erosion, and steep sea cliff. Headlands and bays are often found on the same coastline. A bay is flanked by land on three sides, whereas a headland is flanked by water on three sides. Headlands and bays form on discordant coastlines, where bands of rock of alternating resistance run perpendicular to the coast. Bays form when weak (less resistant) rocks (such as sands and clays) are eroded, leaving bands of stronger (more resistant) rocks (such as chalk, limestone, and granite) forming a headland, or peninsula. Through the deposition of sediment within the bay and the ero ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
