This is a picture of the Sachsenhausen Concentration Camp entrance. This picture basically sums up my grey and gloomy experience. Before going into the camp‚ I was ready to take a lot of pictures and go into this camp with an open-mind‚ instead of thinking about how many human-beings were tortured and killed. I had a feeling the tour of the camp and the atmosphere would feel creepy and sad‚ but it was not necessarily creepy‚ just mainly unreal that the Holocaust really happened and this was the

Concentration camps were places of death and hard labor for Jews. The Nazis controlled these camps‚ by dividing Jews in different camps and sections. Jews had to be creative to avoid getting caught by the Germans. First off the concentration camps were horrific places in which many Jews were put to death. Second‚ Hitler was the one who got Germans to abuse the Jews to death‚ and last; after death the Jews were still misused by the German police and Hitler. The things about the Holocaust that

Concentration of liquid foods is a fundamental operation in many food processes; it is completely different from dehydration. Usually‚ foods‚ which are concentrated‚ remain in the liquid state; while drying produces solid or semisolid foods with significantly lower water content. The concentration of liquid foods has three different methods; evaporation‚ membrane concentration‚ and freeze concentration. Evaporation usages gas liquid phase separation. It has the lowest capital cost and the maximum

The Dachau Concentration Camp was the first camp established in March 1933.It became the first concentration camp made by the Nazis. It was placed by a munitions factory by the city Dachau. It is nearly 10 miles from Munich‚ Germany. In the first year there were 4‚800 prisoners. The first prisoners were German Communists‚ Social Democrats‚ Trade Unionists‚ and other opponents of the Nazis. During 1937 the SS made the prisoners construct a large group of buildings on the grounds of

during the Holocaust was the concentration camps. Many people were affected by the reality of what was happening in Germany. Within Germany‚ there were types of camps that people could be sent to: concentration camps‚ labor camps‚ extermination camps and prisoner-of-war camps. Concentration camps were the Nazis’ way of imprisoning the Jews‚ political antagonists and other people deemed socially unacceptable of the country. If these people were sentenced to a concentration camp and did not arrive

A concentration camp is where prisoners of war‚ enemy aliens‚ and political prisoners are detained and confined‚ typically under harsh conditions‚ or place or situation characterized by extremely harsh conditions. The first concentration camps were established in 1933 for confinement of opponents of the Nazi Party. The supposed opposition soon included all Jews‚ Gypsies‚ and certain other groups. By 1939 there were six camps: Dachau‚ Sachsenhausen‚ Buchenwald‚ Mauthausen‚ Flossenburg

attempting to “Remain loyal to their homeland” and were acting as spies. Even without concrete evidence‚ President Roosevelt signed for them to be relocated. These camps were still located on American soil and were not death camps. The camps were concentration camps‚ a place where they go to basically do hard labor all day. Many Japanese American families sold their homes and assets‚ there was no guarantee that their lives would continue as normal upon their return. Their homes sold for fractions of

Internal assessment on enzyme concentration Enzymes are proteins that act as catalysts and they are the most important type of protein. My aim in this experiment was to investigate the effect of enzyme concentration on the rate of an enzyme (protease) – catalyzed reaction ‚ catalysts speed up chemical reactions . My hypothesis is that the rate as reaction will increase as the concentration of protease in the solution increases so it will take less time for

Title of Practical: The Effect of Concentration on Reaction Rate Aim: To use a simple reaction between sodium thiosulphate and hydrochloric acid to discover concentration this determines how fast chemical reactions occur. Independent Variable: Concentration of hydrochloric acid (%) Dependent Variable: Time taken for chemical reaction to take place (sec) Hypothesis: My prediction is that the increased concentration of the thiosulfate will in turn lead to an increase in the rate of reaction
