Liberation of Nazi Concentration Camps
As the Allies closed in on Hitler's Germany the horror and scale of the Final Solution and concentration camps became all too apparent.This latest Images of War book provides the reader a truly disturbing insight into the Nazi's brutal regime of wholesale murder, torture and starvation. While the Germans attempted to hide the evidence by demolishing much of the camps' infrastructure, the pace of the Soviets' advance through Poland meant that the gas chambers at Majdenak near Lublin were captured intact. Auschwitz had received over a million deportees yet when liberated in January 1945 only a few thousand prisoners were there as the vast majority of surviving prisoners had been sent on forced death marches to more westerly camps such as Ravensbruch and Buchenwald.Condition in these camps deteriorated further due to overcrowding and the spread of deadly diseases. In every camp shocking scenes of death and starvation were encountered.When British troops reached Bergen-Belsen in April 1945, there were some 10,000 unburied dead in addition to the mass graves, in addition to 60,000 starving and sick inmates in utterly appalling conditions. The words and images in this disturbing book are a timely reminder of man's inhumanity to his fellows and that such behaviour should never be repeated.

Concentration Camps : A Global History
In popular perception concentration camps are synonymous with genocide.In fact, the great majority of concentration camps were not sites of genocide.This book shows they were a global phenomenon, with an astonishing range of functions.It asks why they were invented in the twentieth century, not before.Their origin on the colonial periphery raises questions about continuities from imperial warfare to political repression under authoritarian dictatorships and to the contemporary world.Concentration camps are a transnational phenomenon, emerging in learning processes simultaneously (within and between imperial spheres-Britain, Spain, the USA, and Germany around 1900), and diachronically (from then to the First World War, the Gulag, and Nazi camps).Discussing concentration camps not solely in the context of Auschwitz and genocide sometimes encounters strong emotional resistance; the notion that camps had functions other than mass murder seems like breaching a taboo.This sense of shock will spark curiosity for the argument that camps existed (and exist) under a variety of regimes, including at times democratic powers.They are often concomitant with empire-building by revolutionary dictatorships, used as sites of performative violence, and also as central elements of utopian schemes of social and racial transformation.The book contextualizes them with other carceral institutions, and integrates the perspective of perpetrators and the victims.It will reshape the way we think about concentration camps as part of modern civilization, past and present.

Concentration Camps : A Short History
Concentration camps are a relatively new invention, a recurring feature of twentieth century warfare, and one that is important to the modern global consciousness and identity.Although the most famous concentration camps are those under the Nazis, the use of concentration camps originated several decades before the Third Reich, in the Philippines and in the Boer War, and they have been used again in numerous locations, not least during the genocide in Bosnia.They have become defining symbols of humankind's lowest point and basest acts. In this book, Dan Stone gives a global history of concentration camps, and shows that it is not only "mad dictators " who have set up camps, but instead all varieties of states, including liberal democracies, that have made use of them.Setting concentration camps against the longer history of incarceration, he explains how the ability of the modern state to control populations led to the creation of this extreme institution.Looking at their emergence and spread around the world, Stone argues that concentration camps serve the purpose, from the point of view of the state in crisis, of removing a section of the population that is perceived to be threatening, traitorous, or diseased.Drawing on contemporary accounts of camps, as well as the philosophical literature surrounding them, Stone considers the story camps tell us about the nature of the modern world as well as about specific regimes.

Nordhausen Concentration Camp : Then and Now
In the history of Nazi concentration camps, and particularly labour camps, there is probably no place that bears the same stigma of wretchedness as 'Dora-Mittelbau' at Nordhausen.Located in the Harz mountains in central Germany, next to a quarry tunnel system in the Kohnstein mountain, it served to house thousands of slave workers for an underground factory known as the Mittelwerk, which produced three of Germany's best-known secret weapons: the V1 flying bomb, the V2 rocket and jet engines for the Me 262 and Ar 234 fighters.With over 20 kilometres of underground galleries, it was the largest underground factory in the world.Many of the inmates died in indescribable misery, being forced to extend the tunnels with meagre equipment and under ghastly conditions, sometimes not seeing daylight for weeks on end.Started in August 1943, Dora-Mittelbau in due course became the centre of a whole complex of underground factories in the Nordhausen area, with several subsidiary camps being set up.In all, of some 60,000 prisoners sent there between 1943 and 1945, 20,000 were driven to extinction to implement Nazi Germany's secret weapons programme, but they laboured late and in vain, for the products they yielded had little impact on the war.The V1 and V2 are the only weapons which cost more lives in production than in deployment: far more people died producing them than were killed from their impact in London, Antwerp and elsewhere. The history of Nordhausen, already gruesome in itself, ended in a crescendo of violence when, in the final weeks of the war, the surviving inmates were evacuated from the camps in death marches .One group of over a thousand men then became victim of one of the most horrendous of all Nazi atrocities.On April 13, 1945, just outside the town of Gardelegen, their SS camp guards, helped by local troops and Hitlerjugend, locked the prisoners in a big barn and set fire to the inside, burning those inside, killing them with hand-grenades, and shooting anyone who tried to escape from the burning, smoke-filled building.A total of 1,016 men died as a result. When discovered by American troops two days later, Gardelegen quickly became known as the site of one most notorious war crimes committed by the Nazis. In this book, Karel Margry recounts the history of Nordhausen concentration camp and of the Gardelegen massacre in full detail.Both stories are illustrated with unique Then and Now comparison photographs. The book contains the following two stories from ATB magazine:Issue 101: NordhausenAuthor: Karel Margry. 18,165 words, 118 black and white photos. Issue 111: The Gardelegen MassacreAuthor: Karel Margry.Text: 16,189 words, 78 black and white photos. Note:After the Battle s account of Nordhausen, when first published in 1998, was considered so accurate and comprehensive that the Nordhausen Camp Memorial asked whether they could translate it into German and use it as one of their brochures.Thus a special German edition of issue 101 appeared under the title Damals und Heute, which has been reprinted several times.

Is the oxygen concentration higher in the forested mountains?
Yes, the oxygen concentration is typically higher in forested mountains compared to other environments. This is because trees and plants in forests release oxygen as a byproduct of photosynthesis. The dense vegetation in forested mountains helps to maintain higher levels of oxygen in the air. Additionally, the cooler temperatures and higher elevation in mountainous regions can also contribute to higher oxygen concentrations.

Why are concentration camps actually called concentration camps?
Concentration camps are called so because they concentrate a large number of people in a confined area, often under harsh conditions. The term "concentration" refers to the act of bringing together or focusing a specific group of individuals in one place. These camps were historically used to detain and oppress specific groups of people, such as political dissidents, minorities, or prisoners of war, with the goal of controlling and monitoring them closely.

How does the enzyme concentration affect the substrate concentration?
The enzyme concentration directly affects the rate of reaction by increasing the likelihood of collisions between the enzyme and substrate molecules. As the enzyme concentration increases, there are more active sites available to bind with the substrate molecules, leading to a faster rate of reaction. However, once all the active sites are occupied, further increases in enzyme concentration will not have a significant effect on the rate of reaction unless the substrate concentration is also increased. Therefore, the enzyme concentration and substrate concentration both play a crucial role in determining the rate of reaction.

What is the difference between concentration and ion concentration?
Concentration refers to the amount of a substance present in a given volume of solution, typically measured in moles per liter (M). It can refer to the amount of any substance, such as a solute or a solvent, in a solution. On the other hand, ion concentration specifically refers to the amount of ions present in a solution. This can be the concentration of a specific type of ion, such as the concentration of hydrogen ions (H+) in a solution. Therefore, while concentration is a more general term that can refer to any substance, ion concentration specifically refers to the amount of ions in a solution.

What is the difference between molar concentration and mass concentration?
Molar concentration is a measure of the amount of a substance in a given volume of solution, expressed in moles per liter (mol/L). Mass concentration, on the other hand, is a measure of the amount of a substance in a given volume of solution, expressed in grams per liter (g/L). Molar concentration takes into account the molecular weight of the substance, while mass concentration simply considers the mass of the substance present in the solution.

What is the difference between mass concentration and molar concentration?
Mass concentration refers to the amount of solute present in a given volume of solution, typically expressed in units such as grams per liter. On the other hand, molar concentration, also known as molarity, refers to the number of moles of solute present in a given volume of solution, typically expressed in units of moles per liter. In other words, mass concentration is based on the mass of the solute, while molar concentration is based on the number of moles of the solute.

What are concentration disorders?
Concentration disorders, also known as attention disorders, are conditions that affect a person's ability to focus, pay attention, and control their impulses. These disorders can impact a person's ability to perform daily tasks, maintain relationships, and succeed in school or work. Common concentration disorders include attention-deficit/hyperactivity disorder (ADHD) and attention-deficit disorder (ADD). Symptoms of concentration disorders may include difficulty staying focused, being easily distracted, and struggling to follow instructions. Treatment for concentration disorders often involves a combination of therapy, medication, and lifestyle changes.
-
Which concentration camps existed?
Concentration camps existed in various locations during World War II, primarily in Nazi-occupied Europe. Some of the most notorious concentration camps included Auschwitz, Dachau, Buchenwald, and Treblinka. These camps were used by the Nazis to imprison, torture, and exterminate millions of people, primarily Jews, as well as other targeted groups such as Romani people, homosexuals, and political dissidents. The horrors of these camps have left a lasting impact on history and serve as a reminder of the atrocities committed during the Holocaust.
