Hedley Marston
Hedley Ralph Marston FRS FAA (26 August 1900 – 25 August 1965) was an Australian biochemist who worked for the Commonwealth Scientific and Industrial Research Organisation (CSIRO). First published in ''Australian Dictionary of Biography'', Volume 15, (MUP), 2000. Originally published in ''Records of the Australian Academy of Science'', vol. 1, no. 2, Canberra, Australia, 1967. Education Marston was born in Bordertown, South Australia and educated at Unley District High School, Adelaide, where he met Mark Oliphant. He attended the University of Adelaide but did not complete a degree due to failing Mathematics. Career Marston was appointed a demonstrator in the university's department of physiology and biochemistry after a chance meeting with Professor Thorburn Robertson in 1922. On 1 March 1928 he joined Robertson's staff in the division of animal nutrition, CSIRO, Adelaide. Marston greatly impressed Robertson, and became the division's acting-chief on Robertson's death in 19 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bordertown, South Australia
Bordertown, formerly Border Town, is a town and locality in the Australian state of South Australia located in the state's east near the state border with Victoria about east of the state capital of Adelaide. It is where the Dukes Highway and the railway line cross the Tatiara Creek between Adelaide and Melbourne, the capital of Victoria. Bordertown is the commercial and administrative centre of the Tatiara District Council. ''Tatiara'' is the local Aboriginal word for "Good Country". History Bordertown was established in 1852 when a direct route across the Ninety Mile Desert was being planned for gold escorts from the Victorian goldfields to Adelaide. Police Inspector Alexander Tolmer was instructed to create a town as close as practical to the border. Tolmer was upset when the town was not named after him, but that was made up for by naming several sites around Bordertown after him, such as Tolmer Park and Tolmer Takeaway. Land was first offered for sale in the new governme ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mathematics
Mathematics is an area of knowledge that includes the topics of numbers, formulas and related structures, shapes and the spaces in which they are contained, and quantities and their changes. These topics are represented in modern mathematics with the major subdisciplines of number theory, algebra, geometry, and analysis, respectively. There is no general consensus among mathematicians about a common definition for their academic discipline. Most mathematical activity involves the discovery of properties of abstract objects and the use of pure reason to prove them. These objects consist of either abstractions from nature orin modern mathematicsentities that are stipulated to have certain properties, called axioms. A ''proof'' consists of a succession of applications of deductive rules to already established results. These results include previously proved theorems, axioms, andin case of abstraction from naturesome basic properties that are considered true starting points of ...

Fellow Of The Australian Academy Of Science
The Fellowship of the Australian Academy of Science is made up of about 500 Australian scientists. Scientists judged by their peers to have made an exceptional contribution to knowledge in their field may be elected to Fellowship of the Academy. Fellows are often denoted using the post-nominal FAA (Fellow of the Australian Academy of Science). A small number of distinguished foreign scientists with substantial connections to Australian science are elected as Corresponding Members. Fellows are appointed for life; this table also contains deceased fellows.

Doctor Of Science
Doctor of Science ( la, links=no, Scientiae Doctor), usually abbreviated Sc.D., D.Sc., S.D., or D.S., is an academic research degree awarded in a number of countries throughout the world. In some countries, "Doctor of Science" is the degree used for the standard doctorate in the sciences; elsewhere the Sc.D. is a "higher doctorate" awarded in recognition of a substantial and sustained contribution to scientific knowledge beyond that required for a Doctor of Philosophy (PhD). Africa Algeria and Morocco In Algeria, Morocco, Libya and Tunisia, all universities accredited by the state award a "Doctorate" in all fields of science and humanities, equivalent to a PhD in the United Kingdom or United States. Some universities in these four Arab countries award a "Doctorate of the State" in some fields of study and science. A "Doctorate of the State" is slightly higher in esteem than a regular doctorate, and is awarded after performing additional in-depth post-doctorate research or ach ...

Strontium-90
Strontium-90 () is a radioactive isotope of strontium produced by nuclear fission, with a half-life of 28.8 years. It undergoes β− decay into yttrium-90, with a decay energy of 0.546 MeV. Strontium-90 has applications in medicine and industry and is an isotope of concern in fallout from nuclear weapons, nuclear weapons testing, and nuclear accidents. Radioactivity Naturally occurring strontium is nonradioactive and nontoxic at levels normally found in the environment, but 90Sr is a radiation hazard. 90Sr undergoes β− decay with a half-life of 28.79 years and a decay energy of 0.546 MeV distributed to an electron, an antineutrino, and the yttrium isotope 90Y, which in turn undergoes β− decay with a half-life of 64 hours and a decay energy of 2.28 MeV distributed to an electron, an antineutrino, and 90Zr (zirconium), which is stable. Note that 90Sr/Y is almost a pure beta particle source; the gamma photon emission from the decay of 90Y is so infrequent that it ...

McClelland Royal Commission
The McClelland Royal Commission or Royal Commission into British nuclear tests in Australia was an inquiry by the Australian government in 1984–1985 to investigate the conduct of the British in its use, with the then Australian government's permission, of Australian territory and soldiers for testing nuclear weapons. It was chaired by Jim McClelland. Background In September 1950, the then UK Prime Minister, Clement Attlee, requested via a secure telegraph, to Australia's Prime Minister Sir Robert Menzies, to conduct a series of atomic tests at the Monte Bello Islands off the coast of Western Australia. Over the next thirteen years, twelve major British nuclear tests would occur on Australian territory, along with thirty "minor" atomic trials testing sub-systems. The last Vixen B trial occurred in 1963 whereupon the United Kingdom moved its testing operations to the United States. The Royal Commission into nuclear tests arose out of a public outcry, led by media reports, ov ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Nuclear Tests At Maralinga
Between 1956 and 1963, the United Kingdom conducted seven nuclear tests at the Maralinga site in South Australia, part of the Woomera Prohibited Area about north west of Adelaide. Two major test series were conducted: Operation Buffalo in 1956 and Operation Antler the following year. Approximate weapon yields ranged from . The Maralinga site was also used for minor trials, tests of nuclear weapons components not involving nuclear explosions. Kittens were trials of neutron initiators; Rats and Tims measured how the fissile core of a nuclear weapon was compressed by the high explosive shock wave; and Vixens investigated the effects of fire or non-nuclear explosions on atomic weapons. The minor trials, numbering around 550, ultimately generated far more contamination than the major tests. Operation Buffalo consisted of four tests; One Tree () and Breakaway () were detonated on towers, Marcoo () at ground level, and the Kite () was released by a Royal Air Force (RAF) Vickers Valia ...

Sydney Josland
Sydney Walter Josland (30 January 1904 – 28 June 1991) was a New Zealand bacteriologist who specialised in research into Leptospirosis, Salmonella and the control of diseases in animals. Early life and education Born in Christchurch in 1904, Josland was the eldest son of Frederick Josland and Mary Amelia Kerr. He attended West Christchurch District High School. An uncle, Robert Kerr, had made a fortune in South Africa after the Boer War and had retired to Geneva in Switzerland where he invested money into Dr Henri Spahlinger's work on a vaccine for Tuberculosis. Kerr had wanted Josland to study law and had offered to finance his studies. The offer never came through, however, as Kerr died of malarial fever in Geneva on 7 April 1923, aged forty-seven. Perhaps influenced by his uncle's early death, Josland commenced studying towards a medical degree at the University of Otago in Dunedin. He did not finish the degree, due to financial constraints, but gained a Certificate of Profi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coast Disease
Cobalt is a chemical element with the symbol Co and atomic number 27. As with nickel, cobalt is found in the Earth's crust only in a chemically combined form, save for small deposits found in alloys of natural meteoric iron. The free element, produced by reductive smelting, is a hard, lustrous, silver-gray metal. Cobalt-based blue pigments (cobalt blue) have been used since ancient times for jewelry and paints, and to impart a distinctive blue tint to glass, but the color was for a long time thought to be due to the known metal bismuth. Miners had long used the name ''kobold ore'' (German for ''goblin ore'') for some of the blue-pigment-producing minerals; they were so named because they were poor in known metals, and gave poisonous arsenic-containing fumes when smelted. In 1735, such ores were found to be reducible to a new metal (the first discovered since ancient times), and this was ultimately named for the ''kobold''. Today, some cobalt is produced specifically from one of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
