The Holocaust
–
The Holocaust, also referred to as the Shoah, was a genocide in which some six million European Jews were killed by Adolf Hitlers Nazi Germany, and the World War II collaborators with the Nazis. The victims included 1.5 million children, and represented about two-thirds of the nine million Jews who had resided in Europe, killings took place throughout German-occupied Europe, as well as within Nazi Germany, and across all territories controlled by its allies. Other victims of Nazi crimes included ethnic Poles and other Slavs, Soviet citizens and Soviet POWs, communists, homosexuals, Freemasons, Jehovahs Witnesses, some 42,500 detention facilities were utilized in the concentration of victims for the purpose of gross violations of human rights. Over 200,000 people are estimated to have been Holocaust perpetrators, the persecution was carried out in stages, culminating in the policy of extermination of European Jews termed the Final Solution to the Jewish Question. Following Hitlers rise to power, the German government passed laws to exclude Jews from civil society, starting in 1933 the Nazis began to establish a network of concentration camps. After the outbreak of war in 1939 both German and foreign Jews were herded into wartime ghettos, in 1941, as Germany began to conquer new territory in the East, all anti-Jewish measures radicalized. Specialized paramilitary units called Einsatzgruppen murdered around two million Jews in mass shootings actions in less than a year, by mid-1942, victims were being regularly transported by freight trains to extermination camps where, if they survived the journey, most were systematically killed in gas chambers. This continued until the end of World War II in Europe in April–May 1945, the most notable exception was the Warsaw Ghetto uprising of 1943, when thousands of poorly-armed Jewish fighters held the Waffen-SS at bay for four weeks. An estimated 20, 000–30,000 Jewish partisans actively fought against the Nazis, French Jews took part in the French Resistance, which conducted a guerilla campaign against the Nazis and Vichy French authorities. Over a hundred armed Jewish uprisings took place, the term holocaust comes from the Greek adjective holókaustos, a variant of holókautos, referring to an animal sacrifice offered to a god in which the whole animal is completely burnt. Often used substantively in apposition with the noun thysia, the term appears in a fragment of pseudo-Callisthenes, writing in Latin, Jerome Latinized the Greek word as a neuter noun holocaustum, using it to translate references to the Jewish burnt offering in his translations of Exodus and Leviticus. In his Chronicon de rebus gestis Ricardi Primi, Richard of Devizes, the English poet John Milton had used the word to denote a conflagration in his 1671 poem Samson Agonistes and the word gradually developed to mean a massacre thereon. The term was used in the 1950s by historians as a translation of the Jewish word shoah to refer specifically to the Nazi genocide of Jews, the television mini-series Holocaust is credited with introducing the term into common parlance after 1978. The biblical word shoah, meaning calamity became the standard Hebrew term for the Holocaust as early as the 1940s, especially in Europe and Israel. Shoah is preferred by some Jews for several reasons including the offensive nature of the word holocaust which they take to refer to the Greek pagan custom. The Nazis used the phrase Final Solution to the Jewish Question, all branches of Germanys bureaucracy were engaged in the logistics that led to the genocides, turning the Third Reich into what one Holocaust scholar, Michael Berenbaum, has called a genocidal state. Every arm of the countrys sophisticated bureaucracy was involved in the killing process, as prisoners entered the death camps, they were made to surrender all personal property, which was catalogued and tagged before being sent to Germany to be reused or recycled. Berenbaum writes that the Final Solution of the Jewish question was in the eyes of the perpetrators, through a concealed account, the German National Bank helped launder valuables stolen from the victims

Nazi Germany
–
Nazi Germany is the common English name for the period in German history from 1933 to 1945, when Germany was governed by a dictatorship under the control of Adolf Hitler and the Nazi Party. Under Hitlers rule, Germany was transformed into a fascist state in which the Nazi Party took totalitarian control over all aspects of life. The official name of the state was Deutsches Reich from 1933 to 1943, the period is also known under the names the Third Reich and the National Socialist Period. The Nazi regime came to an end after the Allied Powers defeated Germany in May 1945, Hitler was appointed Chancellor of Germany by the President of the Weimar Republic Paul von Hindenburg on 30 January 1933. The Nazi Party then began to eliminate all opposition and consolidate its power. Hindenburg died on 2 August 1934, and Hitler became dictator of Germany by merging the powers and offices of the Chancellery, a national referendum held 19 August 1934 confirmed Hitler as sole Führer of Germany. All power was centralised in Hitlers person, and his word became above all laws, the government was not a coordinated, co-operating body, but a collection of factions struggling for power and Hitlers favour. In the midst of the Great Depression, the Nazis restored economic stability and ended mass unemployment using heavy military spending, extensive public works were undertaken, including the construction of Autobahnen. The return to economic stability boosted the regimes popularity, racism, especially antisemitism, was a central feature of the regime. The Germanic peoples were considered by the Nazis to be the purest branch of the Aryan race, millions of Jews and other peoples deemed undesirable by the state were murdered in the Holocaust. Opposition to Hitlers rule was ruthlessly suppressed, members of the liberal, socialist, and communist opposition were killed, imprisoned, or exiled. The Christian churches were also oppressed, with many leaders imprisoned, education focused on racial biology, population policy, and fitness for military service. Career and educational opportunities for women were curtailed, recreation and tourism were organised via the Strength Through Joy program, and the 1936 Summer Olympics showcased the Third Reich on the international stage. Propaganda minister Joseph Goebbels made effective use of film, mass rallies, the government controlled artistic expression, promoting specific art forms and banning or discouraging others. Beginning in the late 1930s, Nazi Germany made increasingly aggressive territorial demands and it seized Austria and Czechoslovakia in 1938 and 1939. Hitler made a pact with Joseph Stalin and invaded Poland in September 1939. In alliance with Italy and smaller Axis powers, Germany conquered most of Europe by 1940, reichskommissariats took control of conquered areas, and a German administration was established in what was left of Poland. Jews and others deemed undesirable were imprisoned, murdered in Nazi concentration camps and extermination camps, following the German invasion of the Soviet Union in 1941, the tide gradually turned against the Nazis, who suffered major military defeats in 1943

Genocide
–
Genocide is intentional action to destroy a people in whole or in part. The hybrid word genocide is a combination of the Greek word génos, the United Nations Genocide Convention, which was established in 1948, defines genocide as acts committed with intent to destroy, in whole or in part, a national, ethnical, racial or religious group. The term genocide was coined in a 1943 book responding to mass murder of populations in the 20th century, in 1943, Raphael Lemkin created the term genocide in his book Axis Rule in Occupied Europe. The book describes the implementation of Nazi policies in occupied Europe, the term described the systematic destruction of a nation or people, and the word was quickly adopted by many in the international community. The word genocide is the combination of the Greek prefix geno-, Lemkin defined genocide as follows, Generally speaking, genocide does not necessarily mean the immediate destruction of a nation, except when accomplished by mass killings of all members of a nation. The preamble to the 1948 Genocide Convention notes that instances of genocide have taken place throughout history. Lemkins lifelong interest in the murder of populations in the 20th century was initially in response to the killing of Armenians in 1915. He dedicated his life to mobilizing the international community, to together to prevent the occurrence of such events. In a 1949 interview, Lemkin said I became interested in genocide because it happened so many times and it happened to the Armenians, then after the Armenians, Hitler took action. In 1948, the UN General Assembly adopted the Convention on the Prevention, the CPPCG was adopted by the UN General Assembly on 9 December 1948 and came into effect on 12 January 1951. The USSR argued that the Conventions definition should follow the etymology of the term, and may have feared greater international scrutiny of its own Great Purge. Other nations feared that including political groups in the definition would invite international intervention in domestic politics. ”The conventions purpose and scope was later described by the United Nations Security Council as follows, In 2007 the European Court of Human Rights, noted in its judgement on Jorgic v. In the same judgement the ECHR reviewed the judgements of several international and municipal courts judgements, in the case of Onesphore Rwabukombe the German Supreme Court adhered to its previous judgement and didnt follow the narrow interpretation of the ICTY and the ICJ. The phrase in whole or in part has been subject to discussion by scholars of international humanitarian law. The International Criminal Tribunal for the Former Yugoslavia found in Prosecutor v. Radislav Krstic – Trial Chamber I – Judgment – IT-98-33 ICTY8 that Genocide had been committed. The aim of the Genocide Convention is to prevent the destruction of entire human groups. The Appeals Chamber goes into details of other cases and the opinions of respected commentators on the Genocide Convention to explain how they came to this conclusion. The judges continue in paragraph 12, The determination of when the part is substantial enough to meet this requirement may involve a number of considerations

North Korea
–
North Korea, officially the Democratic Peoples Republic of Korea, is a country in East Asia, constituting the northern part of the Korean Peninsula. Pyongyang is both the capital as well as its largest city. To the north and northwest the country is bordered by China and by Russia along the Amnok, the country is bordered to the south by South Korea, with the heavily fortified Korean Demilitarized Zone separating the two. Negotiations on reunification failed, and in 1948 two separate governments were formed, the communist Democratic Peoples Republic of Korea in the north, an invasion initiated by North Korea led to the Korean War. The Korean Armistice Agreement brought about a ceasefire, and no peace treaty was ever signed. North Korea officially describes itself as a self-reliant socialist state and formally holds elections, critics regard it as a totalitarian dictatorship. Various outlets have called it Stalinist, particularly noting the elaborate cult of personality around Kim Il-sung, International organizations have assessed human rights violations in North Korea as belonging to a category of their own, with no parallel in the contemporary world. Over time, North Korea has gradually distanced itself from the world communist movement, Juche, an ideology of national self-reliance, was introduced into the constitution as a creative application of Marxism–Leninism in 1972. The means of production are owned by the state through state-run enterprises, most services such as healthcare, education, housing and food production are subsidized or state-funded. From 1994 to 1998, North Korea suffered from a famine that resulted in the deaths of between 0.24 and 3.5 million people, and the continues to struggle with food production. North Korea follows Songun, or military-first policy and it is the country with the highest number of military and paramilitary personnel, with a total of 9,495,000 active, reserve, and paramilitary personnel. Its active duty army of 1.21 million is the fourth largest in the world, after China, North Korea is an atheist state with no official religion and where public religion is discouraged. The name Korea derives from the name Goryeo, the name Goryeo itself was first used by the ancient kingdom of Goguryeo in the 5th century as a shortened form of its name. The 10th-century kingdom of Goryeo succeeded Goguryeo, and thus inherited its name, the modern spelling of Korea first appeared in the late 17th century in the travel writings of the Dutch East India Companys Hendrick Hamel. After the division of the country into North and South Korea, the two sides used different terms to refer to Korea, Chosun or Joseon in North Korea, in 1948, North Korea adopted Democratic Peoples Republic of Korea as its new legal name. After the First Sino-Japanese War and the Russo-Japanese War, Korea was occupied by Japan, Japan tried to suppress Korean traditions and culture and ran the economy primarily for its own benefit. Korean resistance groups known as Dongnipgun operated along the Sino-Korean border, some of them took part in allied action in China and parts of South East Asia. One of the leaders was the communist Kim Il-sung, who later became the leader of North Korea

Extermination camp
–
This genocide of the Jewish people of Europe was the Third Reichs Final Solution to the Jewish question. It is now known as the Holocaust. In 1941, the experience gained in the killing of these hospital patients led to the creation of extermination camps for the implementation of the Final Solution. By then, the Jews were already confined to new ghettos and interned in Nazi concentration camps along with other targeted groups, including Roma, and the Soviet POWs. The Nazi Endlösung der Judenfrage, based on the killing of Europes Jews by gassing, began during Operation Reinhard. Responsibility for the logistics were to be executed by the programme administrator, notably, the order preceded the Wannsee Conference by three months, but the gassings at Kulmhof north of Łódź using gas vans began already in December, under Sturmbannführer Herbert Lange. The camp at Bełżec was operational by March 1942, with leadership brought in from Germany under the guise of Organisation Todt, Auschwitz concentration camp was fitted with brand new gassing bunkers in March 1942. Majdanek had them built in September, todeslagers were designed specifically for the systematic killing of people delivered en masse by the Holocaust trains. The executioners did not expect the prisoners to more than a few hours beyond arrival at Belzec, Sobibór. The Jewish men, women and children were delivered from the ghettos for special treatment in an atmosphere of terror by uniformed police battalions from both, Orpo and Schupo. From March 1936, all Nazi concentration camps were managed by the SS-Totenkopfverbände, who operated extermination camps from 1941 as well. An SS anatomist, Dr. Johann Kremer, after witnessing the gassing of victims at Birkenau, wrote in his diary on 2 September 1942 and they dont call Auschwitz the camp of annihilation for nothing. The distinction was evident during the Nuremberg trials, when Dieter Wisliceny was asked to name the extermination camps, then, when asked How do you classify the camps Mauthausen, Dachau, and Buchenwald. He replied, They were normal concentration camps, from the point of view of the department of Eichmann, irrespective of round-ups for extermination camps, the Nazis abducted millions of foreigners for slave labour in other types of camps, which provided perfect cover for the extermination programme. Prisoners represented about a quarter of the workforce of the Reich, with mortality rates exceeding 75 percent due to starvation, disease, exhaustion, executions. On top of that, the new death camps outside the borders of the Third Reich proper could be kept secret from the German civil populace. The killing method was based on experience gained by the SS during the secretive Aktion T4 programme of involuntary euthanasia, there were two types of death chambers operating during the Holocaust. The three killing centres of Einsatz Reinhard were constructed predominantly for the extermination of Polands Jews trapped in the Nazi ghettos

Criticism of Holocaust denial
–
The methodologies of Holocaust deniers has been criticized as being based on a predetermined conclusion that ignores extensive historical evidence to the contrary. The claims of deniers are grounded in flawed research, biased statements, courts of law have also rejected Holocaust denial claims and passed several laws against holocaust denial in 14 European countries. The Nizkor Project, a group opposed to Holocaust denial claims, in a letter dated 1919 Hitler mentions that an unshakable aim of a strong national government must be the removal of the Jews. In a speech on 30 January 1942, Hitler repeated his prophecy of 1939 and he war will not end as the Jews imagine it will, namely with the uprooting of the Aryans, but the result of this war will be the complete annihilation of the Jews. Now for the first time they will not bleed other people to death, but for the first time the old Jewish law of an eye for an eye, and -- world Jewry may as well know this -- the further these battles spread, the more anti-Semitism will spread. It will find nourishment in every camp and in every family when it discovers the ultimate reason for the sacrifices it has to make. And the hour will come when the most evil universal enemy of all time will be finished and this process is of vast importance, and will have unforeseeable consequences that will require time. But it can no longer be halted and it must only be guided in the right direction. Nevertheless, and in contrast to the T4 euthanasia program, no document written or signed by Hitler ordering the Holocaust has ever been found, deniers have claimed that this lack of order shows genocide was not Nazi policy. Mr Justice Gray concluded that this was a double standard, heinrich Himmler instructed his camp commandants to destroy records, crematoria, and other signs of mass extermination. As one of examples, the bodies of the 25,000 mostly Latvian Jews whom Friedrich Jeckeln. Similar operations were undertaken at Belzec, Treblinka and other death camps and we can now very openly talk about this among ourselves, and yet we will never discuss this publicly. Let us thank God that we had within us enough self-evident fortitude never to discuss it among us, every one of us was horrified, and yet every one clearly understood that we would do it next time, when the order is given and when it becomes necessary. I am now referring to the evacuation of the Jews, to the extermination of the Jewish people, historian Peter Longerich states that Hitler. avoided giving a clear written order to exterminate Jewish civilians. Wide protest was evoked when Hitlers authorisation of the T4 program became public knowledge in Germany and this made Hitler realise that such undertakings must be done secretly in order to avoid criticism. Critics also point out that if Hitler did sign such an order in the first place, many statements from the Nazis from 1941 onwards addressed the imminent extermination of the Jews. When speaking about this document under oath, David Irving is quoted as saying There is no explicit reference, David Cole has previously stated that those who consider themselves revisionists have yet to provide an adequate explanation of this document. When questioned by interrogators if orders for the extermination of Jews were delegated in writing by Himmler, Adolf Eichmann states, I never saw a written order, all I know is that Heydrich said to me, The Führer has ordered the physical extermination of the Jews

Prussian blue
–
Prussian blue is a dark blue pigment with the idealized chemical formula Fe 718. To better understand the situation in this complex compound the formula can also be written as Fe 43 · xH 2O. Another name for the color is Berlin blue or, in painting, Turnbulls blue is the same substance, but is made from different reagents, and its slightly different color stems from different impurities. Prussian blue was the first modern synthetic pigment and it is employed as a very fine colloidal dispersion, as the compound itself is not soluble in water. It is famously complex, owing to the presence of variable amounts of other ions, the pigment is used in paints, and it is the traditional blue in blueprints. In medicine, Prussian blue is used as an antidote for certain kinds of metal poisoning, e. g. by thallium. In particular it was used to absorb 137Cs+ from those poisoned in the Goiânia accident, the therapy exploits Prussian blues ion exchange properties and high affinity for certain soft metal cations. It is on the World Health Organizations List of Essential Medicines, Prussian blue lent its name to prussic acid, which was derived from it. In Germany, hydrogen cyanide is called Blausäure, and Joseph Louis Gay-Lussac gave cyanide its name, from the Greek word κυανός, because it is easily made, cheap, nontoxic, and intensely colored, Prussian blue has attracted many applications. It was adopted as a pigment very soon after its invention and was almost immediately used in oil, watercolor. The dominant uses are for pigments, about 12,000 tonnes of Prussian blue are produced annually for use in black, a variety of other pigments also contain the material. Engineers blue and the pigment formed on cyanotypes—giving them their common name blueprints, certain crayons were once colored with Prussian blue. It is also a popular pigment in paints, similarly, Prussian blue is the basis for laundry bluing. Prussian blues ability to incorporate monocations makes it useful as a agent for certain heavy metal poisons. Pharmaceutical-grade Prussian blue in particular is used for people who have ingested thallium or radioactive caesium, according to the International Atomic Energy Agency, an adult male can eat at least 10 g of Prussian blue per day without serious harm. The U. S. Prussian blue is a common stain used by pathologists to detect the presence of iron in biopsy specimens. The original stain formula, known historically as Perls Prussian blue after its inventor, German pathologist Max Perls, used separate solutions of potassium ferrocyanide, iron deposits in tissue then form the purple Prussian blue dye in place, and are visualized as blue or purple deposits. The formula is known as Perls Prussian blue and as Perls Prussian blue

Aktion T4
–
Aktion T4 was the postwar designation for a programme of involuntary euthanasia in Nazi Germany. Under the programme certain German physicians were authorized to select patients deemed incurably sick, after most critical medical examination, about half of the victims were from church-run asylums. Several reasons for the programme have been offered, including eugenics, compassion, reducing suffering, racial hygiene, cost effectiveness and pressure on the welfare budget. After the nominal end of the programme, physicians in German and Austrian facilities continued many of the practices of Aktion T4, the unofficial continuation of the policy led to additional deaths by medicine and similar means, resulting in 93,521 beds emptied by the end of 1941. The technology, personnel and techniques developed were instrumental in the implementation of Nazi genocides, the term Aktion T4 came into use after the war, before that German terminology included Euthanasie and Gnadentod. The euthanasia programme was part of the evolution of the policy of murder that culminated in the extermination of Jews of Europe during the Holocaust. In his book Mein Kampf, Hitler wrote that one day racial hygiene, the idea of sterilising those carrying hereditary defects or exhibiting what was thought to be hereditary antisocial behaviour was widely accepted. Canada, Denmark, Switzerland and the US had passed laws for the sterilisation of people before Germany. Studies conducted in the 1920s ranked Germany as a country that was unusually reluctant to introduce sterilisation legislation, the policy and research agenda of racial hygiene and eugenics were promoted by Emil Kraepelin. Sterilisation was also legalised for chronic alcoholism and other forms of social deviance and it is estimated that 360,000 people were sterilised under this law between 1933 and 1939. In 1935, Hitler told the Leader of Reich Doctors, Gerhard Wagner and he wrote that he intended to radically solve the problem of the mental asylums in such an event. Although officially started in September 1939, Aktion T4 was initiated with a case in late 1938. Hitler instructed his personal physician, Karl Brandt, to evaluate a familys petition for the killing of their blind. The child, born near Leipzig and identified as Gerhard Kretschmar eventually, was killed in July 1939, Hitler instructed Brandt to proceed in the same manner in all similar cases. Three weeks after the killing of the boy, the Reich Committee for the Scientific Registering of Hereditary and it was to prepare and proceed with the registration of sick children or newborns identified as defective. Secret killing of infants began in 1939 and increased after the war started, by 1941 more than 5,000 children had been killed. Hitler was in favour of killing those whom he judged to be unworthy of life and this issue, according to the Nazi regime, assumed new urgency in wartime. The German eugenics movement had an extreme wing even before the Nazis came to power, as early as 1920, Alfred Hoche and Karl Binding advocated killing people whose lives were unworthy of life

Operation Barbarossa
–
Operation Barbarossa was the code name for Nazi Germanys invasion of the Soviet Union during World War II, which was launched on Sunday 22 June 1941. In the two leading up to the invasion, the two countries signed political and economic pacts for strategic purposes. Nevertheless, the German High Command began planning an invasion of the Soviet Union in July 1940, over the course of the operation, about four million Axis personnel invaded the western Soviet Union along a 2, 900-kilometer front, the largest invasion force in the history of warfare. In addition to troops, the Wehrmacht employed some 600,000 motor vehicles, the offensive marked an escalation of the war, both geographically and in the formation of the Allied coalition. Despite their successes, the German offensive stalled in the Battle of Moscow and was pushed back by the Soviet winter counteroffensive. The Red Army repelled the Wehrmachts strongest blows and forced the unprepared Germans into a war of attrition, the Wehrmacht would never again mount a simultaneous offensive along the entire strategic Soviet–Axis front. The failure of the operation drove Hitler to demand further operations of limited scope inside the Soviet Union, such as Case Blue. The failure of Operation Barbarossa proved a point in the fortunes of the Third Reich. Most importantly, the operation opened up the Eastern Front, in more forces were committed than in any other theater of war in world history. The German armies captured 5,000,000 Soviet prisoners of war who were not granted protections stipulated in the Geneva Conventions, a majority of them never returned alive. The Nazis deliberately starved 3.1 million of the prisoners to death as part of a Hunger Plan that aimed to reduce the population of Eastern Europe, over a million Soviet Jews were murdered by Einsatzgruppen death squads and gassing as part of the Holocaust. On 10 February 1939, Hitler told his commanders that the next war would be purely a war of Weltanschauungen. Totally a peoples war, a racial war, on 23 November, once World War II had already started, Hitler declared that racial war has broken out and this war shall determine who shall govern Europe, and with it, the world. The racial policy of Nazi Germany viewed the Soviet Union as populated by non-Aryan Untermenschen, Hitler claimed in Mein Kampf that Germanys destiny was to turn to the East as it did six hundred years ago. Accordingly, it was stated Nazi policy to kill, deport, or enslave the majority of Russian and other Slavic populations and repopulate the land with Germanic peoples, under the Generalplan Ost. Likening the Soviets to the forces of Genghis Khan, Hitler told Croatian military leader Slavko Kvaternik that the Mongolian race threatened Europe. Following the invasion, Wehrmacht officers told their soldiers to target people who were described as Jewish Bolshevik subhumans, the Mongol hordes, the Asiatic flood, German army commanders cast the Jews as the major cause behind the partisan struggle. The main guideline policy for German troops was Where theres a partisan, theres a Jew, many German troops viewed the war in Nazi terms and regarded their Soviet enemies as sub-human

Exhaust gas
–
Exhaust gas or flue gas is emitted as a result of the combustion of fuels such as natural gas, gasoline, petrol, biodiesel blends, diesel fuel, fuel oil, or coal. According to the type of engine, it is discharged into the atmosphere through an exhaust pipe, flue gas stack and it often disperses downwind in a pattern called an exhaust plume. A2013 study by MIT indicates that 53,000 early deaths occur per year in the United States alone because of vehicle emissions. According to another study from the university, traffic fumes alone cause the death of 5,000 people every year just in the United Kingdom. The largest part of most combustion gas is nitrogen, water vapor, and carbon dioxide, Exhaust gas temperature is important to the functioning of the catalytic converter of an internal combustion engine. It may be measured by an exhaust gas temperature gauge, EGT is also a measure of engine health in gas-turbine engines. During the first two minutes after starting the engine of a car that has not been operated for several hours, inefficient catalytic converter under cold conditions, Catalytic converters are very inefficient until up to their operating temperature. This time has much reduced by moving the converter closer to the exhaust manifold. The small converter handles the start-up emissions, which enough time for the larger main converter to heat up. Further improvements can be realised in many ways, including heating, thermal battery, chemical reaction preheating, flame heating. The requirements were phased in beginning with 2004 vehicles and all new cars, in spark-ignition engines the gases resulting from combustion of the fuel and air mix are called exhaust gases. The composition varies from petrol to diesel engines, but is around these levels, The 10% oxygen for diesel is likely if the engine was idling and it is much less if the engine is running under load. People exposed to it should wear a gas mask, in aircraft gas turbine engines, exhaust gas temperature is a primary measure of engine health. Typically the EGT is compared with an engine power indication called engine pressure ratio. For example, at full power EPR there will be a maximum permitted EGT limit, once an engine reaches a stage in its life where it reaches this EGT limit, the engine will require specific maintenance in order to rectify the problem. The amount the EGT is below the EGT limit is called EGT margin, the EGT margin of an engine will be greatest when the engine is new, or has been overhauled. For most airlines, this information is monitored remotely by the airline maintenance department by means of ACARS. In jet engines and rocket engines, exhaust from propelling nozzles which in some applications shows shock diamonds, Flue gas Flue gas emissions from fossil fuel combustion In steam engine terminology the exhaust is steam that is now so low in pressure that it can no longer do useful work

Einsatzgruppen
–
Einsatzgruppen were Schutzstaffel paramilitary death squads of Nazi Germany that were responsible for mass killings, primarily by shooting, during World War II. As ordered by Nazi leader Adolf Hitler, the Wehrmacht cooperated with the Einsatzgruppen, historian Raul Hilberg estimates that between 1941 and 1945 the Einsatzgruppen and related auxiliary troops killed more than two million people, including 1.3 million Jews. The total number of Jews murdered during the Holocaust is estimated at 5.5 to 6 million people, after the close of World War II,24 senior leaders of the Einsatzgruppen were prosecuted in the Einsatzgruppen Trial in 1947–48, charged with crimes against humanity and war crimes. Fourteen death sentences and two sentences were handed out. Four additional Einsatzgruppe leaders were tried and executed by other nations. The Einsatzgruppen were formed under the direction of SS-Obergruppenführer Reinhard Heydrich and operated by the Schutzstaffel before, the Einsatzgruppen had its origins in the ad hoc Einsatzkommando formed by Heydrich to secure government buildings and documents following the Anschluss in Austria in March 1938. Originally part of the Sicherheitspolizei, two units of Einsatzgruppen were stationed in the Sudetenland in October 1938, when military action turned out not to be necessary due to the Munich Agreement, the Einsatzgruppen were assigned to confiscate government papers and police documents. They also secured government buildings, questioned senior civil servants, and arrested as many as 10,000 Czech communists, from September 1939, the Reichssicherheitshauptamt had overall command of the Einsatzgruppen. Action T4 mainly took place from 1939 to 1941, but the killings continued until the end of the war, initially the victims were shot by the Einsatzgruppen and others, but gas chambers were put into use by spring 1940. In response to Adolf Hitlers plan to invade Poland, Heydrich re-formed the Einsatzgruppen to travel in the wake of the German armies, membership at this point was drawn from the SS, the Sicherheitsdienst, and the police. Heydrich placed SS-Obergruppenführer Werner Best in command, who chose leaders for the forces and their subgroups, called Einsatzkommandos. Some had previously been members of groups such as the Freikorps. There must be no Polish leaders, where Polish leaders exist they must be killed, the Sonderfahndungsbuch Polen — lists of people to be killed — had been drawn up by the SS as early as May 1939. The Einsatzgruppen performed these murders with the support of the Volksdeutscher Selbstschutz, members of the SS, the Wehrmacht, and the Ordnungspolizei also shot civilians during the Polish campaign. Approximately 65,000 civilians were killed by the end of 1939, in addition to leaders of Polish society, they killed Jews, prostitutes, Romani people, and the mentally ill. Psychiatric patients in Poland were initially killed by shooting, but by spring 1941 gas vans were widely used, seven Einsatzgruppen of battalion strength operated in Poland. Each was subdivided into four Einsatzkommandos of company strength, many senior army officers were only too glad to leave these genocidal actions to the task forces, as the killings violated the rules of warfare as set down in the Geneva Conventions. However, Hitler had decreed that the army would have to tolerate, some army commanders complained about unauthorised shootings, looting, and rapes committed by members of the Einsatzgruppen and the Volksdeutscher Selbstschutz, to little effect

Jews
–
The Jews, also known as the Jewish people, are an ethnoreligious group originating from the Israelites, or Hebrews, of the Ancient Near East. Jews originated as a national and religious group in the Middle East during the second millennium BCE, the Merneptah Stele appears to confirm the existence of a people of Israel, associated with the god El, somewhere in Canaan as far back as the 13th century BCE. The Israelites, as an outgrowth of the Canaanite population, consolidated their hold with the emergence of the Kingdom of Israel, some consider that these Canaanite sedentary Israelites melded with incoming nomadic groups known as Hebrews. The worldwide Jewish population reached a peak of 16.7 million prior to World War II, but approximately 6 million Jews were systematically murdered during the Holocaust. Since then the population has risen again, and as of 2015 was estimated at 14.3 million by the Berman Jewish DataBank. According to the report, about 43% of all Jews reside in Israel and these numbers include all those who self-identified as Jews in a socio-demographic study or were identified as such by a respondent in the same household.
