Jean Danysz (biologist)
Jean Danysz (1860 – 1928) was a Polish pathologist with a considerable career in France, having spent much of his adult life at the Pasteur Institute in Paris. In 1890 he isolated Salmonella typhimurium. In 1893, he was involved in research into the flour moth, "scourge of the flour mill", Ephestia kuehniella. In 1898, he was working on rinderpest. In 1903, he worked on a way to control the vole plague in France. He was, in 1903, the first person to use radium to treat malignant diseases. He was contacted in 1905 regarding Australia's rabbit plagues and responding to the New South Wales government's offer of £25,000 for a novel solution to the country's rabbit pest problem, he arrived in Australia the following year to advise on biological control measures. He brought a strain of Pasteurella bacteria which he had developed to selectively kill feral rabbits and conducted a series of trials on Broughton Island, New South Wales coast with his team. He left in May 1907 after a s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pasteur Institute
The Pasteur Institute (french: Institut Pasteur) is a French non-profit private foundation dedicated to the study of biology, micro-organisms, diseases, and vaccines. It is named after Louis Pasteur, who invented pasteurization and vaccines for anthrax and rabies. The institute was founded on 4 June 1887, and inaugurated on 14 November 1888. For over a century, the Institut Pasteur has researched infectious diseases. This worldwide biomedical research organization based in Paris was the first to isolate HIV, the virus that causes AIDS, in 1983. Over the years, it has been responsible for discoveries that have enabled medical science to control diseases such as diphtheria, tetanus, tuberculosis, poliomyelitis, influenza, yellow fever, and plague. Since 1908, ten Institut Pasteur scientists have been awarded the Nobel Prize for medicine and physiology—the 2008 Nobel Prize in Physiology or Medicine was shared between two Pasteur scientists.

Jan Kazimierz Danysz
Jean Danysz (11 March 1884 – 4 November 1914) born Jan Kazimierz Danysz, was a French physicist of Polish extraction. He was an assistant of Maria Skłodowska-Curie and notable in the development of beta spectrometry. Danysz made considerable advances on the magnetic deflection techniques of Baeyer, Hahn and Meitner, placing the source (he used radium) in a capillary tube under a slit, with a photographic plate in the same horizontal plane. By this means the known number of lines (later understood to be conversion lines) superimposed on the beta energy spectrum of RaB + RaC went from 9 to 27 (later work by Robinson and Rutherford found 64; 16 from RaB and 48 from RaC). He finished his doctoral thesis in 1913, and by 1914 he was considered by Rutherford as a leading researcher into beta decay, but he did no further work. He enlisted in the French army in 1914 and was killed in action near Cormicy. Publications J. Danysz, Le Radium 9, 1 (1912); 10, 4 (1913) Danysz, J. ...

Marian Danysz
Marian Danysz (March 17, 1909 – February 9, 1983) was a Polish physicist, Professor of Physics at Warsaw University. Son of Jan Kazimierz Danysz. In 1952, he co-discovered with Jerzy Pniewski a new kind of matter, an atomic nucleus, which alongside a proton and neutron contains a third particle: the lambda hyperon (). Ten years later, they obtained a hypernucleus A hypernucleus is similar to a conventional atomic nucleus, but contains at least one hyperon in addition to the normal protons and neutrons. Hyperons are a category of baryon particles that carry non-zero strangeness quantum number, which is co ... in excited state, and the following year a hypernucleus with two lambda hyperons. 20th-century Polish physicists 1909 births 1983 deaths Fellows of the American Physical Society French emigrants to Poland {{Poland-scientist-stub ...

Beta Particles
A beta particle, also called beta ray or beta radiation (symbol β), is a high-energy, high-speed electron or positron emitted by the radioactive decay of an atomic nucleus during the process of beta decay. There are two forms of beta decay, β− decay and β+ decay, which produce electrons and positrons respectively. Beta particles with an energy of 0.5 MeV have a range of about one metre in air; the distance is dependent on the particle energy. Beta particles are a type of ionizing radiation and for radiation protection purposes are regarded as being more ionising than gamma rays, but less ionising than alpha particles. The higher the ionising effect, the greater the damage to living tissue, but also the lower the penetrating power of the radiation. Beta decay modes β− decay (electron emission) An unstable atomic nucleus with an excess of neutrons may undergo β− decay, where a neutron is converted into a proton, an electron, and an electron antineutrino (the antip ...

Marie Curie
Marie Salomea Skłodowska–Curie ( , , ; born Maria Salomea Skłodowska, ; 7 November 1867 – 4 July 1934) was a Polish and naturalized-French physicist and chemist who conducted pioneering research on radioactivity. She was the first woman to win a Nobel Prize, the first person and the only woman to win a Nobel Prize twice, and the only person to win a Nobel Prize in two scientific fields. Her husband, Pierre Curie, was a co-winner of her first Nobel Prize, making them the first-ever married couple to win the Nobel Prize and launching the Curie family legacy of five Nobel Prizes. She was, in 1906, the first woman to become a professor at the University of Paris. She was born in Warsaw, in what was then the Kingdom of Poland, part of the Russian Empire. She studied at Warsaw's clandestine Flying University and began her practical scientific training in Warsaw. In 1891, aged 24, she followed her elder sister Bronisława to study in Paris, where she earned her highe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Broughton Island, New South Wales
Broughton Island is an island 14 km north-east of Port Stephens, New South Wales, Australia. It is part of the Myall Lakes National Parkbr>(map) History Archaeology indicates that the certain ancestors of the Worimi people inhabited the island for an otherwise apparently indeterminate period of two-thousand years, and whatever name those people may have had for the island itself remains unknown. It lay within the territory of the Garrawerrigal branch (''nurra'') of the Woromi. "Garrawerrigal" meant "the people of the sea", from ''garoowa''=sea. ''Niritba'' was "the home of the mutton bird" in their language. Broughton Island was seen by James Cook commanding HM Bark ''Endeavour'' on 11 May 1770: he mistook it for a headland and called it Black Head. After its insularity was discovered, it was renamed Broughton Islands, and so appears on the 1852 Admiralty chart, ''Australia, East Coast.

Salmonella Typhimurium
''Salmonella enterica'' subsp. ''enterica'' is a subspecies of ''Salmonella enterica'', the rod-shaped, flagellated, aerobic, Gram-negative bacterium. Many of the pathogenic serovars of the ''S. enterica'' species are in this subspecies, including that responsible for typhoid. Serovars ''S. enterica'' subsp. ''enterica'' contains a large number of serovars which can infect a broad range of vertebrate hosts. The individual members range from being highly host-adapted (only able to infect a narrow range of species) to displaying a broad host range. A number of techniques are currently used to differentiate between serotypes. These include looking for the presence or absence of antigens, phage typing, molecular fingerprinting and biotyping, where serovars are differentiated by which nutrients they are able to ferment. A possible factor in determining the host range of particular serovars is phage-mediated acquisition of a small number of genetic elements that enable infection of a ...

Pasteurella
__NOTOC__ ''Pasteurella'' is a genus of Gram-negative, facultatively anaerobic bacteria. ''Pasteurella'' species are nonmotile and pleomorphic, and often exhibit bipolar staining ("safety pin" appearance). Most species are catalase- and oxidase-positive. The genus is named after the French chemist and microbiologist, Louis Pasteur, who first identified the bacteria now known as ''Pasteurella multocida'' as the agent of chicken cholera. Pathogenesis Many ''Pasteurella'' species are zoonotic pathogens, and humans can acquire an infection from domestic animal bites. In cattle, sheep, and birds, ''Pasteurella'' species can cause a life-threatening pneumonia; in cats and dogs, however, ''Pasteurella'' is not a cause of disease, and constitutes part of the normal flora of the nose and mouth. ''Pasteurella haemolytica'' is a species that infects mainly cattle and horses: '' P. multocida'' is the most frequent causative agent in human ''Pasteurella'' infection.
