Hubble Bubble (astronomy)

edit

In astronomy, a Hubble bubble would be (if it existed) "a departure of the local value of the Hubble constant from its globally averaged value." (Jha et al. 2007).

Quotes from http://theastronomist.fieldofscience.com/2010/07/hubble-bubble.html:

  • "Technically a Hubble bubble is defined as a region of space wherein there is an observed departure of the local value of the Hubble constant from its cosmologically averaged value."
  • "The Hubble Bubble is wildly speculative and precision cosmology has almost completely defeated it as a credible explanation. "
  • "Of course, despite difficulties the analysis, they find that in their parametrization there is evidence for more than the simply effect of local Milky Way dust implying doom for the Hubble Bubble. So the Hubble Bubble has been burst."

"a local monopole in the peculiar velocity field, perhaps caused by a local void in the mass density."

Gustav Gassner

It has no inline references, so I am going to need to work on this to create its analog in English Wikipedia. Sharktopustalk 21:20, 27 January 2011 (UTC)

Johann Gustav Gassner (born January 17, 1881 in Berlin; † 5 February 1955 in Lüneburg) was a German botanist and Phytomedicine. Its official botanical author abbreviation is "Gassner.

Life [Edit]

Originally from a Salzburg emigrants Gassner visited the Friedrichs-Gymnasium in Berlin and then studied from 1899 to 1905 in Halle and Berlin, botany and natural sciences. He received his PhD in 1906 at the Agricultural University of Berlin and then started work on Getreidemykosen at the Imperial Biological Research Centre for Agriculture and Forestry in Berlin-Dahlem. [1] In 1907 he became professor of botany and plant pathology at the Agricultural University of Montevideo, Uruguay. In 1910 he returned to Germany and married Lili Fassier-Farnell, with whom he later five children together, four sons and a daughter.

He first worked at the State Botanical Institute, Hamburg. From 1911 he taught at the University of Kiel, 1915, he was an assistant to a professor at the University of Rostock. On 1st World War II was a bacteriological laboratory Gassner Board of the German army. 1918 Gassner eventually became a professor of Botany at the Technical University of Braunschweig. There he headed the Institute of Botany and the Botanical Garden. In 1926 he took over the leadership of the newly established Botanical Research Institute and was president of the German Botanical Society, since 1931, he was a member of the German Academy of Sciences, Leopoldina. In 1932 he was elected Rector of the Technical University of Braunschweig. However, soon after he fell to the Nazis in conflict because he objected to the massive intervention in the academic self-government. His situation worsened in 1933 very much and he resigned. On 1 April 1933 he was "to have participated in preparation of high treason" under the pretext of being arrested. After his release in September Gassner emigrated to Turkey. In Ankara, he was the expert of the Ministry of Agriculture and director of the Plant Protection Service operates. In 1939 he returned to Germany and worked as head of the biological department of the AG Fahlberg-List in Magdeburg. Here he worked on the development and testing of plant protection products. His main field was there Germisan, a means for dressing seed based on organic mercury compounds.

In 1945 he again took over the principal's office in Braunschweig. From 1946 to 1948 Gassner was a chairman of the Rectors' Conference. In 1949 he was appointed to the German Research Council, a forerunner of the German Research Foundation. Significantly its share in building the Braunschweig Research Center (Federal Biological Research Centre, Federal Agricultural Research Centre) was. The University of Göttingen awarded him an honorary doctorate in 1951 and he was, on the occasion of his 70th Birthday, was appointed Honorary Senator of the TH Braunschweig. In the same year he retired, he represented his subject but still acting. 1952 he gave the Federal President Theodor Heuss, the Grand Cross of Merit of the Federal Republic for his outstanding achievements in the areas of crop protection and for the benefit of agriculture.

German to English translation Scientific Focus [Edit]

Gassner's scientific achievements are in the field of plant pathology and applied biology. He examined smuts and fire diseases of cereals. In addition, the physiology and ecology of the rust fungus was another focus of his work. In addition, the numerous essays on the germination physiology are mentioned. Crucial he improved the methods of seed dressing. Leading the vernalization research was his work on the development conditions of the grains. Fonts [edit]

There are a total of 200 publications by Gassner. In addition to numerous journal articles, he wrote the book Microscopic examination of plant food and beverages, which was first published 1931st It has been opened several times and continued after his death. The current sixth Edition of 2007, Berthold Hohmann edited and is titled Microscopic examination of plant food and feed: the Gassner. ISBN 3-89947-256-X.
