Torsten Thunberg
Torsten Ludvig Thunberg (30 June 1873 – 4 December 1952) was a Swedish physiologist and biochemist who worked on metabolic oxidation, including examinations of key steps in the tricarboxylic acid cycle, producing insights that were later elucidated by Hans A. Krebs. He was a professor of physiology at the University of Lund. The ''Thunberg grill illusion'', also called the thermal grill illusion was discovered by him. The so-called Thunberg tube for examining biological redox reactions was also named after him. Life and work Thunberg was born in Torsaker, Sweden to businessman Per Erik Thunberg and Wendela Maria Elisabeth Hård. He studied medicine at the University of Uppsala and received an MD with a thesis on epidermal sensory organs and perception. He worked at the Institute of Physiological Chemistry in 1893-94 under Olof Hammarsten and the next two years at the Institute of Physiology at Uppsala under Frithiof Homgren. His 1896 work noted what is now called the "therm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Haven Emerson
John Haven Emerson (February 5, 1906 – February 4, 1997) was an American inventor of biomedical devices, specializing in respiratory equipment. He is perhaps best remembered for his work in improving the iron lung. Early life Emerson was born in 1906 in New York City, the son of Dr. Haven Emerson, Health Commissioner of New York City, and Grace Parrish Emerson, the sister of Maxfield Parrish. He was named for his paternal grandfather (1840–1913), who was also a medical doctor. At the age of 22, he bought a rudimentary machine shop from the estate of a local inventor. He moved the equipment to a small warehouse in Harvard Square, in Cambridge, Massachusetts, where he built research apparatus for professors and researchers of Boston-area medical schools, and produced many inventions over the following years. In 1928, he designed a Barcroft-Warburg apparatus for tissue respiration studies. In 1930, he designed a new type of micromanipulator which was valuable in early physiology s ...

Royal Swedish Academy Of Sciences
The Royal Swedish Academy of Sciences () is one of the Swedish Royal Academies, royal academies of Sweden. Founded on 2 June 1739, it is an independent, non-governmental scientific organization that takes special responsibility for promoting natural sciences and mathematics and strengthening their influence in society, whilst endeavouring to promote the exchange of ideas between various disciplines. The goals of the academy are: * To be a forum where researchers meet across subject boundaries, * To offer a unique environment for research, * To provide support to younger researchers, * To reward outstanding research efforts, * To communicate internationally among scientists, * To advance the case for science within society and to influence research policy priorities * To stimulate interest in mathematics and science in school, and * To disseminate and popularize scientific information in various forms. Every year, the academy awards the Nobel Prizes in Nobel Prize in Physics, phy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Temperance Movement
The temperance movement is a social movement promoting Temperance (virtue), temperance or total abstinence from consumption of alcoholic beverages. Participants in the movement typically criticize alcohol intoxication or promote teetotalism, and its leaders emphasize alcohol (drug), alcohol's negative effects on people's Health effects of alcohol, health, personalities, and family lives. Typically the movement promotes alcohol education and it also demands the passage of new Alcohol law, laws against the sale of alcohol: either regulations on the availability of alcohol, or the prohibition of it. During the 19th and early 20th centuries, the temperance movement became prominent in many countries, particularly in English-speaking, Scandinavian, and majority Protestant ones, and it eventually led to national prohibitions Prohibition in Canada, in Canada (1918 to 1920), Norway (spirits only from 1919 Norwegian prohibition referendum, 1919 to 1926 Norwegian continued prohibition ref ...

Hjalmar Öhrvall
Hjalmar () and Ingeborg () were a legendary Swedish duo. The male protagonist Hjalmar and his duel for Ingeborg figures in the '' Hervarar saga'' and in '' Orvar-Odd's saga'', as well as in ''Gesta Danorum'', '' Lay of Hyndla'' and a number of Faroese ballads. Hjalmar never lost a battle until meeting a berserker wielding the cursed sword Tyrfing. A tale of two heroes Hjalmar was one of the mythical Swedish king Yngvi's housecarls at Uppsala. He and princess Ingeborg were in love, but the king said no to his requests for marriage, since he hoped for a suitor with a better pedigree. Hjalmar's reputation as a courageous and valiant warrior was great and it reached the most remote parts of Norway, where the Norwegian hero Orvar-Odd felt a desire to test his fighting skills with Hjalmar. Thus Orvar-Odd sailed to Sweden with five ships and met Hjalmar who had fifteen ships. Hjalmar could not accept such an uneven balance of strength and sent away ten of his own ships so that the forc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Philip Drinker
Philip Drinker (December 12, 1894 – October 19, 1972) was an American industrial hygienist. With Louis Agassiz Shaw, he invented the first widely used iron lung in 1928. Family and early life Drinker's father was railroad man and Lehigh University president Henry Sturgis Drinker; his siblings included lawyer and musicologist Henry Sandwith Drinker, Jr., pathologist Cecil Kent Drinker, businessman James Drinker, and biographer Catherine Drinker Bowen. After graduating from St. George's and Princeton in 1915, Philip Drinker trained as a chemical engineer at Lehigh for two years. Drinker was hired to teach industrial illumination and ventilation at Harvard Medical School and soon joined his brother Cecil and colleagues Alice Hamilton and David L. Edsall on the faculty of the nascent Harvard School of Public Health in 1921 or 1923. He studied, taught, and wrote textbooks and scholarly works on a variety of topics in industrial hygiene; the iron lung itself was or ...

Prior Art
Prior art (also known as state of the art or background art) is a concept in patent law used to determine the patentability of an invention, in particular whether an invention meets the novelty and the inventive step or non-obviousness criteria for patentability. In most systems of patent law, prior art is generally defined as anything that is made available, or disclosed, to the public that might be relevant to a patent's claim before the effective filing date of a patent application for an invention. However, notable differences exist in how prior art is specifically defined under different national, regional, and international patent systems. The prior art is evaluated by patent offices as part of the patent granting process in what is called "substantive examination" of a patent application in order to determine whether an invention claimed in the patent application meets the novelty and inventive step or non-obviousness criteria for patentability. It may also be considered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hans Krebs (biochemist)
Sir Hans Adolf Krebs, FRS (, ; 25 August 1900 – 22 November 1981) was a German-British biologist, physician and biochemist. He was a pioneer scientist in the study of cellular respiration, a biochemical process in living cells that extracts energy from food and oxygen and makes it available to drive the processes of life. He is best known for his discoveries of two important sequences of chemical reactions that take place in the cells of nearly all organisms, including humans, other than anaerobic microorganisms, namely the citric acid cycle and the urea cycle. The former, often eponymously known as the "Krebs cycle", is the sequence of metabolic reactions that allows cells of oxygen-respiring organisms to obtain far more ATP from the food they consume than anaerobic processes such as glycolysis can supply; and its discovery earned Krebs a Nobel Prize in Physiology or Medicine in 1953. With Hans Kornberg, he also discovered the glyoxylate cycle, a slight variation of the ci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
