Example Input: Context_1 : The Nobel Prize in Chemistry (Swedish: "Nobelpriset i kemi" ) is awarded annually by the Royal Swedish Academy of Sciences to scientists in the various fields of chemistry. It is one of the five Nobel Prizes established by the 1895 will of Alfred Nobel, who died in 1896. These prizes are awarded for outstanding contributions in chemistry, physics, literature, peace, and physiology or medicine. As dictated by Nobel's will, the award is administered by the Nobel Foundation and awarded by a committee that consists of five members elected by the Royal Swedish Academy of Sciences. The first Nobel Prize in Chemistry was awarded in 1901 to Jacobus Henricus van 't Hoff, of the Netherlands. Each recipient receives a medal, a diploma and a monetary award prize that has varied throughout the years. In 1901, van 't Hoff received 150,782 SEK, which is equal to 7,731,004 SEK in December 2007. The award is presented in Stockholm at an annual ceremony on December 10, the anniversary of Nobel's death. Context_2 : The Nobel Prizes are awarded annually by the Royal Swedish Academy of Sciences, the Swedish Academy, the Karolinska Institute, and the Norwegian Nobel Committee to individuals who make outstanding contributions in the fields of Chemistry, Physics, Literature, Peace, Physiology or Medicine and Economics. All but the economics prize were established by the 1895 will of Alfred Nobel, which dictates that the awards should be administered by the Nobel Foundation. The Nobel prize in Economics, or The Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel, was established in 1968 by the Sveriges Riksbank, the central bank of Sweden, for outstanding contributions in the field of Economics. Each prize is awarded by a separate committee; the Royal Swedish Academy of Sciences awards the Prizes in Physics, Chemistry, and Economics, the Swedish Academy awards the Prize in Literature, the Karolinska Institute awards the Prize in Physiology or Medicine, and the Norwegian Nobel Committee awards the Prize in Peace. Each recipient receives a medal, a diploma and a cash prize that has varied throughout the years. Context_3 : This is a list of Danish Nobel laureates. Since the Nobel Prize was established per the will of Swedish inventor Alfred Nobel in 1895, 12 of the prize winners have been from Denmark. The first Danish Nobel laureate was Niels Ryberg Finsen, who won a Nobel Prize for medicine in 1903 for his work in using light therapy to treat diseases. The most recent Danish Nobel Prize winner was Jens Skou who won the prize in chemistry for his discovery over the enzyme, Na+/K+-ATPase in 1997. To date, of the 13 Nobel Prizes won by Danish people, 5 have been for medicine, 3 have been for physics, 3 have been for literature, 1 has been for chemistry and one has been for peace. Context_4 : Lars Onsager (November 27, 1903 October 5, 1976) was a Norwegian-born American physical chemist and theoretical physicist.

Context_5 : The Leverhulme Medal is awarded by the Royal Society every three years "for an outstandingly significant contribution in the field of pure or applied chemistry or engineering, including chemical engineering". It was created in 1960 after a donation by the Leverhulme Trust to mark the 300-year anniversary of the foundation of the Royal Society, and is accompanied by a 2000 gift. Since its creation it has been awarded 17 times, and unlike other Royal Society medals such as the Royal Medal, it has never been awarded to a woman or to the same person multiple times. Citizens of the United Kingdom have won the medal 16 out of the 17 times; the only foreign recipient was Man Mohan Sharma, an Indian citizen who was awarded the medal in 1996 "for his work on the dynamics of multi-phase chemical reactions in industrial processes". Two of the Leverhulme Medal winners also won the Nobel Prize in Chemistry: Archer John Porter Martin, who won the medal in 1963 for "his distinguished and fundamental discoveries in chromatography and its application" and the Nobel Prize in 1952, and Cyril Norman Hinshelwood, who won the medal in 1960 for "his outstanding contributions to physical chemistry" and the Nobel Prize in 1956. Context_6 : Hendrik Antoon Lorentz (18 July 1853 4 February 1928) was a Dutch physicist who shared the 1902 Nobel Prize in Physics with Pieter Zeeman for the discovery and theoretical explanation of the Zeeman effect. He also derived the transformation equations underpinning Albert Einstein's theory of special relativity. Context_7 : The Nobel Prize in Physiology or Medicine (Swedish: "Nobelpriset i fysiologi eller medicin" ) is awarded annually by the Swedish Karolinska Institute to scientists and doctors in the various fields of physiology or medicine. It is one of the five Nobel Prizes established by the 1895 will of Alfred Nobel (who died in 1896), awarded for outstanding contributions in chemistry, physics, literature, peace, and physiology or medicine. As dictated by Nobel's will, the award is administered by the Nobel Foundation and awarded by a committee that consists of five members and an executive secretary elected by the Karolinska Institute. While commonly referred to as the Nobel Prize in Medicine, Nobel specifically stated that the prize be awarded for "physiology or medicine" in his will. Because of this, the prize can be awarded in a broader range of fields. The first Nobel Prize in Physiology or Medicine was awarded in 1901 to Emil Adolf von Behring, of Germany. Each recipient receives a medal, a diploma and a monetary award that has varied throughout the years. In 1901, von Behring received 150,782 SEK, which is equal to 7,731,004 SEK in December 2008. In 2013, the prize was awarded to James E. Rothman, Randy W. Schekman and Thomas C. Sudhof; they were recognised "after discovering how cells precisely transport material". The award is presented in Stockholm at an annual ceremony on December 10, the anniversary of Nobel's death. Context_8 : The Nobel Prize in Physics (Swedish: "Nobelpriset i fysik" ) is a yearly award given by the Royal Swedish Academy of Sciences for those who conferred the most outstanding contributions for mankind in the field of physics. It is one of the five Nobel Prizes established by the will of Alfred Nobel in 1895 and awarded since 1901; the others being the Nobel Prize in Chemistry, Nobel Prize in Literature, Nobel Peace Prize, and Nobel Prize in Physiology or Medicine. Context_9 : Since 1901, the Nobel Prize in Literature (Swedish: "Nobelpriset i litteratur" ) has been awarded annually to an author from any country who has, in the words of the will of Alfred Nobel, produced "in the field of literature the most outstanding work in an ideal direction" (original Swedish: "den som inom litteraturen har producerat det mest framstaende verket i en idealisk riktning"). Though individual works are sometimes cited as being particularly noteworthy, here "work" refers to an author's work as a whole. The Swedish Academy decides who, if anyone, will receive the prize in any given year. The academy announces the name of the chosen laureate in early October. It is one of the five Nobel Prizes established by the will of Alfred Nobel in 1895; the others are the Nobel Prize in Chemistry, Nobel Prize in Physics, Nobel Peace Prize, and Nobel Prize in Physiology or Medicine.

The band released four studio albums before parting ways in 1993. After coming back together to play a reunion concert in 2006, they released their fifth studio album "The Ones I Condemn" on Brazilian label Marquee Records in 2009. Although the band faced numerous lineup changes, especially in their early days, founding guitarists Urbinati, Rico and bassist Scott Watts recorded every studio album and demo and drummer Gus Pynn on everything but the "Apocalypse Inside" demo and CD. Context_6 : Deliverance is the 1989 self-titled debut album by the Christian speed/thrash metal band Deliverance. The original Intense Records pressing is now considered a valuable collectable.

It was officially re-released late 2008 with 2 bonus tracks on Retroactive Records. The album was ranked at No. 44 on "Metal Hammer"' s top 50 thrash metal albums of all-time list. In 2010, "HM Magazine" listed "Deliverance" No. 31 on its Top 100 Christian Rock Albums of All Time list stating that "'If You Will' into 'The Call' is almost as good as metal gets (-Doug Van Pelt)" and that "this record would forever change and impact me and the Christian metal music scene as we knew it!"(-Bill Balford). Heaven's Metal fanzine ranked it No. 3 on its Top 100 Christian metal albums of all-time list. About.com writer Dan Marsicano wrote "Metal with a religious concept is not for everybody, and Deliverance doesn't try to pander to the secular crowd. So, if you don't mind a little preaching, their music is straight-to-the-gut thrash metal at a time where the genre was getting more expansive with its themes and sound. For giving Christian metal a thrash hero to rally behind, Deliverance gets the nod for this week's Retro Recommendation."
