Siberia (/saɪˈbɪəriə/; Russian: Сиби́рь, tr. Sibir'; IPA: [sʲɪˈbʲirʲ] ( listen)) is an extensive region constituting almost all of Northern Asia. Comprising the central and eastern portion of the Russian Federation, it was part of the Soviet Union (USSR) from its beginning, as its predecessor states, the Tsardom of Russia and the Russian Empire, conquered it during the 16th to 19th centuries.

Encompassing much of the Eurasian Steppe, the territory of Siberia extends eastward from the Ural Mountains to the watershed between the Pacific and Arctic drainage basins, and southward from the Arctic Ocean to the hills of north-central Kazakhstan and the national borders of Mongolia and China. Siberia makes up about 77% of Russia's territory (13.1 million square kilometres), but has only 28% (40 million people) of Russia's population.

Some sources say that the word Siberia originates from the Turkic for "sleeping land". Another version is that this name was the ancient tribal name of the Sabirs, Turkic nomads later assimilated to Siberian Tatars. The modern usage of the name appeared in the Russian language after the conquest of the Siberian Khanate.

Raymond Paul "Ray" Mears (born 7 February 1964) is an English woodsman, instructor, author and TV presenter. His TV appearances cover bushcraft and survival techniques, and he is best known for the TV series Ray Mears' Bushcraft, Ray Mears' World of Survival, Extreme Survival, Survival with Ray Mears, Wild Britain with Ray Mears and Ray Mears Goes Walkabout.

Mears grew up in Kenley, Greater London, and the North Downs, where he discovered a countryside abundant with wildlife. Educated at Reigate Grammar School, a co-educational independent school in Reigate, Surrey, he learned to track foxes in the forest at a young age. As a boy, he desired to sleep out on the trail, but unable to afford camping equipment, he resorted to setting up camp using what he could find in his surroundings.

Mears's enthusiasm for his subject, combined with his broad knowledge of survival and the uses which may be made of plants, trees and other natural materials found in woodland, forest or desert, have made him a popular figure in TV broadcasting in the UK.^{[citation needed]} He has travelled extensively across the world for his TV series and has learned survival techniques from the indigenous peoples he has met. In his programmes he demonstrates his knowledge of the wild, how to find food from seeds, berries, roots and other growing things, and how to survive by constructing temporary shelters, fires and canoes from natural materials.

Dyanne Thorne (born October 14, 1943, in Greenwich, Connecticut, USA) is an American actress, nude model for pin-up magazines, and former Las Vegas showgirl. She is best known for starring in four "Ilsa" sexploitation movies that influenced the Nazi exploitation film genre.

Thorne first appeared as "Lahna Monroe" in the 1964 sexploitation film Sin in the Suburbs from grindhouse director Joseph W. Sarno. Her co-star, Audrey Campbell, would soon star as the dominatrix Olga in a series of "roughie" films (Olga's House of Shame, et al.). Thorne continued to make exploitation films and sex comedies such as Love Me Like I Do (1970) and Wam-Bam, Thank You, Spaceman (1973) before attaining notoriety as Ilsa, a cruel Nazi dominatrix similar to Campbell's Olga. Ilsa, She Wolf of the SS (1974) was a surprise hit that spawned three sequels and a flood of imitators, creating a Nazi exploitation film subgenre.

The first Ilsa movie was filmed on the prison camp sets left behind from the Hogan's Heroes television series. Thorne's Ilsa is a brutal buxom commandant of a German prisoner-of-war camp during World War II. She sexually and physically abuses her male and female prisoners and uses them for diabolical medical experiments. The film, which was banned in Germany,^{[citation needed]} was notorious for its level of sadism and for portraying Nazi cruelty as sexual actions.
