Context paragraphs:
Dominik Wydra: Dominik Wydra (born 21 March 1994) is an Austrian footballer who plays for Erzgebirge Aue.  He has represented various Austrian youth national teams, and was captain of the U21 Austrian team.

Barbara Gasser: Barbara Gasser is an Austrian artistic gymnast.  She represented Austria at the 2012 Summer Olympics.  She finished 46th in the all-around with a total of 50.633.  Gasser lives and trains in Sarnia, Ontario.  Her family moved to Canada in 2003, but she still has Austrian citizenship and competes for Austria.  Gasser is a 13-time Austrian national champion, and she has competed at 6 European Championships.

Viktor Schauberger: Viktor Schauberger (30 June 1885 in Holzschlag, Upper Austria – 25 September 1958 in Linz, Austria) was an Austrian forest caretaker, naturalist, pseudoscientistref>Ronald Engert: "Die Forellenturbine als Prinzip der kostenlosen Energiegewinnung.  Freie Energie durch Implosion". </ref>, philosopher, inventor and biomimicry experimenter.

Walter Pektor: Walter Pektor was an Austrian Olympic javelin thrower.  He represented his country in the men's javelin throw at the 1968 Summer Olympics.  His distance was an 82.16 in the qualifiers and a 77.40 in the finals.  He was the former Austrian record holder and nine-time Austrian champion.

Austria in the Eurovision Song Contest 2004: Austria was represented by Tie Break and the song "Du bist".  The Austrian National Final 'song.null.vier' was held on March 5, 2004, hosted by Boris Uran and Oliver Auspitz with the winner being chosen by televoting.  One wildcard was reserved for a newcomer, while the other nine contenders were established Austrian acts, supplied by the country's record companies.  The winner of the competition was the boy-band Tie-Break who sang the German song "Du bist".  Waterloo & Robinson already represented Austria back in 1976 where they ended up in 5th position with a song called 'My little world'.  Tie Break consists of Stefan di Bernardo, Tommy Pegram, and Thomas Elzenbaumer.

Polynucleobacter asymbioticus: Polynucleobacter asymbioticus is a aerobic, catalase- and oxidase-positive, chemo-organotrophic, nonmotile, free-living bacterium of the genus "Polynucleobacter".  The type strain was isolated from a small pond located in the Austrian Alps in the area of Salzburg and described as a new subspecies of "Polynucleobacter necessarius" in 2009.  The classification of the type strain was hampered by the fact that its closest described relative represented obligate endosymbionts, i.e. "P. necessarius", not available as a pure culture suitable for standard tests (DNA-DNA hybridization experiments) for delineation of prokaryotic species.  Therefore, the strain was preliminarily placed in the subspecies "P. necessarius" subsp.  "asymbioticus".  Later sequencing of the genome of the type strain revealed that the strain represented a novel species within the genus "Polynucleobacter".  Therefore, its taxonomic rank was lifted from the subspecies to the species level.  Strains of "P. asymbioticus" dwell as planktonic organisms in acidic, humic-rich freshwater systems.  Comparative genome analyses revealed that "P. asymbioticus" represents an atypical member of the family "Burkholderiaceae" regarding its small genome size and its passive lifestyle.  A recent study used a collection of 37 "P. asymbioticus" strains isolated from various ponds located in a larger region of the Austrian Alps to gain insights in the evolution of "Polynucleobacter" bacteria.

Henriett Koósz: Henriett Koósz (born 14 February 1980, Kőszeg) is an Austrian wheelchair tennis player.  As a member of the Austrian Paralympic wheelchair tennis team, she competed at the 2012 Paralympics in London.  In 2016, she represented Austria in para-badminton at the Austrian Open.

Vortex Garten: The Vortex Garden is a privately owned public garden in the Hessian city of Darmstadt (Germany).  It is a pantheistic permaculture garden at the art nouveau area of Mathildenhoehe and alludes to Viktor Schauberger’s discovery of “levitational force” through artistic depictions by internationally renowned sculptors including John Wilkes, Jacopo Foggini, Jerome Abel Seguin and Hyesung Hyun.  The garden is the private property of Henry Nold of Darmstadt, but is open to the public.

Austrian Federal Computing Centre: The Austrian Federal Computing Centre or Bundesrechenzentrum (BRZ) is a public information technology (IT) service provider based in Vienna.  The organisation develops and operates e-government services for the Austrian Federal Government, including the Federal Ministries and the Federal Chancellery.  In 1997 the BRZ was outsourced from the Federal Ministry of Finance as an organisational spin-off on the basis of a Federal Law, since then it acts as a limited liability company.  The Austrian Federal Computing Centre is owned by the Republic of Austria, represented by the Federal Ministry of Finance.

Monika Schachl: Monika Schachl (born August 21, 1978 in Mondsee) is a retired Austrian professional road cyclist and mountain biker.  She represented her nation Austria at the 2008 Summer Olympics, and later captured three Austrian championship titles each in mountain biking, road race, and time trial during the 2005 and 2008 seasons.  Before her official retirement in 2009, Schachl rode for Team Uniqa Graz in the women's elite professional events on the UCI Women's World Cup, UCI World Championships, and Austrian Championships.
