Nitrile rubberNitrile rubber, also known as nitrile butadiene rubber, NBR, Buna-N, and acrylonitrile butadiene rubber, is a synthetic rubber derived from acrylonitrile (ACN) and butadiene. Trade names include Perbunan, Nipol, Krynac and Europrene. This rubber is unusual in being resistant to oil, fuel, and other chemicals. NBR is used in the automotive and aeronautical industry to make fuel and oil handling hoses, seals, grommets, and self-sealing fuel tanks. It is used in the nuclear industry to make protective gloves.
Primo LeviPrimo Michele Levi (ˈpriːmo ˈlɛːvi; 31 July 1919 – 11 April 1987) was an Italian chemist, partisan, writer, and Jewish Holocaust survivor. He was the author of several books, collections of short stories, essays, poems and one novel. His best-known works include If This Is a Man (1947, published as Survival in Auschwitz in the United States), his account of the year he spent as a prisoner in the Auschwitz concentration camp in Nazi-occupied Poland; and The Periodic Table (1975), a collection of mostly autobiographical short stories each named after a chemical element as it played a role in each story, which the Royal Institution named the best science book ever written.
If This Is a ManIf This Is a Man (Se questo è un uomo se kˈkwesto ˌɛ un ˈwɔːmo; United States title: Survival in Auschwitz) is a memoir by Italian Jewish writer Primo Levi, first published in 1947. It describes his arrest as a member of the Italian anti-fascist resistance during the Second World War, and his incarceration in the Auschwitz concentration camp (Monowitz) from February 1944 until the camp was liberated on 27 January 1945. Primo Levi was born in 1919 in Turin. His forebears were Piedmontese Jews.
ArbeitslagerArbeitslager (ˈʔaʁbaɪtsˌlaːɡɐ) is a German language word which means labor camp. Under Nazism, the German government (and its private-sector, Axis, and collaborator partners) used forced labor extensively, starting in the 1930s but most especially during World War II. Another term was Zwangsarbeitslager ("forced labor camp"). The Nazis operated several categories of Arbeitslager for different categories of inmates.
Synthetic rubberA synthetic rubber is an artificial elastomer. They are polymers synthesized from petroleum byproducts. About 32 million metric tons of rubbers are produced annually in the United States, and of that amount two thirds are synthetic. Synthetic rubber, just like natural rubber, has many uses in the automotive industry for tires, door and window profiles, seals such as O-rings and gaskets, hoses, belts, matting, and flooring. They offer a different range of physical and chemical properties which can improve the reliability of a given product or application.
KruppThe Krupp family (see pronunciation) is a prominent 400-year-old German dynasty from Essen, noted for its production of steel, artillery, ammunition and other armaments. The family business, known as Friedrich Krupp AG (Friedrich Krupp AG Hoesch-Krupp after acquiring Hoesch AG in 1991 and lasting until 1999), was the largest company in Europe at the beginning of the 20th century, and was the premier weapons manufacturer for Germany in both world wars.
Auschwitz concentration campAuschwitz concentration camp (Konzentrationslager Auschwitz (kɔntsɛntʁaˈtsi̯oːnsˌlaːɡɐ ˈʔaʊʃvɪts); also KL Auschwitz or KZ Auschwitz) was a complex of over 40 concentration and extermination camps operated by Nazi Germany in occupied Poland (in a portion annexed into Germany in 1939) during World War II and the Holocaust. It consisted of Auschwitz I, the main camp (Stammlager) in Oświęcim; Auschwitz II-Birkenau, a concentration and extermination camp with gas chambers; Auschwitz III-Monowitz, a labor camp for the chemical conglomerate IG Farben; and dozens of subcamps.
Zyklon BZyklon B (tsyˈkloːn ˈbeː; translated Cyclone B) was the trade name of a cyanide-based pesticide invented in Germany in the early 1920s. It consists of hydrogen cyanide (prussic acid), as well as a cautionary eye irritant and one of several adsorbents such as diatomaceous earth. The product is notorious for its use by Nazi Germany during the Holocaust to murder approximately 1.1 million people in gas chambers installed at Auschwitz-Birkenau, Majdanek, and other extermination camps.
Polish areas annexed by Nazi GermanyFollowing the Invasion of Poland at the beginning of World War II, nearly a quarter of the entire territory of the Second Polish Republic was annexed by Nazi Germany and placed directly under the German civil administration. The rest of Nazi-occupied Poland was renamed as the General Government district. The annexation was part of the "fourth partition of Poland" by Nazi Germany and the Soviet Union, outlined months before the invasion, in the Molotov–Ribbentrop Pact.
The HolocaustThe Holocaust was the genocide of European Jews during World War II. Between 1941 and 1945, Nazi Germany and its collaborators systematically murdered some six million Jews across German-occupied Europe, around two-thirds of Europe's Jewish population. The murders were carried out primarily through mass shootings and poison gas in extermination camps, chiefly Auschwitz-Birkenau, Treblinka, Belzec, Sobibor, and Chełmno in occupied Poland. The Nazis developed their ideology based on racism and pursuit of "living space" and seized power in early 1933.
