Pentane is an organic compound with the chemical formula of . It is an alkane with five carbon atoms. Usually, "pentane" represents all three isomers ("n"-pentane, isopentane and neopentane). But in the IUPAC, pentane only represents "n"-pentane. In the IUPAC, the other two isomers is 2-methylbutane and 2,2-dimethylpropane. Cyclopentane's chemical formula is , so it is not an isomer of pentane.
All isomers of pentane burn with oxygen to make carbon dioxide and water:
Max Schreck
Friedrich Gustav Max Schreck (6 September 1879 – 20 February 1936) was a German actor. He is remembered for his role in the horror movie "Nosferatu" (1922).
Schreck was born in Berlin-Friedenau, on 6 September 1879. He received his training at the " (the State Theatre of Berlin). He completed his studies in 1902. He made his stage debut in Meseritz and Speyer. He then toured Germany for two years appearing at theatres in Zittau, Erfurt, Bremen, Lucerne, Gera, and Frankfurt am Main. Schreck then joined Max Reinhardt's company of performers in Berlin. Many of Reinhardt's troupe made a significant contribution to movies.
Between 1919 and 1922, Schreck appeared at the Munich Kammerspiele. He had a role in the expressionist production of Bertolt Brecht's debut, " ("Drums in the Night"). He played the "freakshow landlord" Glubb. During this time he also worked on his first movie "Der Richter von Zalamea". In 1921, he was hired by Prana Film for their first and only movie, "Nosferatu". The company declared itself bankrupt after the movie was released. They did not want to pay copyright infringement costs to "Dracula" author Bram Stoker's widow. Schreck portrayed Count Orlok in the movie. The character was very similar to Count Dracula.
In 1923, Schreck was still in Munich. He appeared in a 16-minute (one-reeler) slapstick, "surreal comedy" written by Bertolt Brecht entitled ' ("Mysteries of a Barbershop"). Schreck appeared as a blind man in the film ' ("The Street") the same year.
Schreck's second collaboration with "Nosferatu" director F. W. Murnau was the 1924 comedy "" ("The Grand Duke's Finances"). Murnau did not like the final product.
In 1926, Schreck returned to the Kammerspiele in Munich. He continued to act in movies. He made the transition to "talkies". He died in 1936 in Munich of a heart attack. On 19 February 1936, Schreck had just played The Grand Inquisitor in the play "". That evening he felt unwell. The doctor sent him to the hospital where he died early the next morning His obituary praised his role as The Miser in Molière's comedy play. He was buried on 14 March 1936 at Wilmersdorfer Waldfriedhof in Berlin.
Schreck was married to actress Fanny Normann. She appeared in a few movies. She was often credited as Fanny Schreck. The word "schreck" is also the German word for "fright", or "terror". Because of this, many authors who were unaware of Schreck's on-stage credits (and ignorant of the rather sparse details of his personal life) speculated that there was really no such person, and that Schreck was, in fact, some well-known actor who had chosen to adopt a pseudonym for his role in "Nosferatu". One of the prime "suspects" was Alfred Abel; however, a careful examination of the photographs of these two actors is sufficient to dispel such notions.
Schreck's contemporaries recalled he was a loner with an unusual sense of humor. He was skilled in playing grotesque characters. One reported he lived in "a remote and strange world". He was said to spend time walking through dark forests.
The person and performance of Max Schreck in "Nosferatu" has been fictionalized by actor Willem Dafoe in E. Elias Merhige's "Shadow of the Vampire". In a sort of secret history, "Shadow" posits that Schreck actually "was" a vampire.
Scriptwriter Daniel Waters created the character Max Shreck for the film "Batman Returns" and compared him to the character Max Schreck played in "Nosferatu". "Variety" claimed the name was an in-joke. Shreck was a character created exclusively for the movie, absent from the comics, and serves as one of the main antagonists.
Greater Yellowstone Ecosystem
The Greater Yellowstone Ecosystem is one of the last remaining large, nearly intact ecosystems in the northern temperate zone of the Earth. It is partly in Yellowstone National Park. Its management has been controversial: the area is a flagship site for conservation groups that promote ecosystem management. The Greater Yellow Ecosystem (GYE) is a kind of natural laboratory in landscape ecology and geology. It is a world-renowned recreational site, and home to the animals of Yellowstone.
The Yellowstone National Park boundaries were drawn in 1872 to include all the geothermal basins in the area. By the 1970s, the grizzly bear's ("Ursus arctos") range in and near the park became the unofficial minimum boundary of a Greater Yellowstone ecosystem. This had at least . Since then, definitions of the greater ecosystem's size have steadily grown larger. A 1994 study listed the size as , while a 1994 speech by a Greater Yellowstone Coalition leader enlarged that to .
In 1985 the United States House of Representatives Subcommittees on Public Lands and National Parks and Recreation held a joint subcommittee hearing on Greater Yellowstone. The result was a 1986 report by the Congressional Research Service which said that different agencies were not working well together, and the area's essential values were at risk.
There are other areas within the Greater Yellowstone area which are managed by federal authorities. They include the Gallatin, Custer, Caribou-Targhee, Bridger-Teton and Shoshone National Forests, the John D. Rockefeller, Jr. Memorial Parkway, the National Elk Refuge and Grand Teton National Park. The GYE also includes some private lands around those managed by the U.S. Government.
Outside of Yellowstone National Park, ten wilderness areas have been established in the National Forests since 1966 to get more habitat protection than usual.
