Concentration Camps : A Global History
A global and comprehensive history of a modern institution of inhumanity. In popular perception concentration camps are synonymous with genocide and Nazi racial extermination.Yet concentration camps were and are a global phenomenon, not restricted to Nazi Germany, used at times even by democracies, with an astonishing range of functions. Drawing together a wide range of multi-lingual archival research and synthesising a broad secondary literature, Alan Kramer provides here a comprehensive history of concentration camps, charting their first establishment at the beginning of the twentieth century on the colonial periphery, through their most extreme and inhuman instances in the mid-twentieth century, to their continued use today.Concentration camps are shown to be a truly transnational phenomenon that emerged both 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).Such camps existed (and exist) under a variety of regimes, often concomitant with empire-building by revolutionary dictatorships, as sites of genocide, mass murder, and performative violence, but also as central elements of utopian schemes of social and racial transformation.Integrating the perspective of perpetrators and the victims and contextualising them within the historiography of other carceral institutions, the book will reshape the way we think about concentration camps as part of modern civilization, past and present.

How high is the concentration of H3O+?
The concentration of H3O+ is a measure of the acidity of a solution. It is typically expressed in terms of pH, which is a logarithmic scale ranging from 0 to 14. A high concentration of H3O+ corresponds to a low pH value, indicating a more acidic solution. For example, a pH of 1 would indicate a very high concentration of H3O+, while a pH of 7 would indicate a neutral solution with equal concentrations of H3O+ and OH-.

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.

Is inhaling mold in very high concentration dangerous?
Inhaling mold in very high concentrations can be dangerous, especially for individuals with respiratory conditions or weakened immune systems. Exposure to high levels of mold spores can lead to allergic reactions, respiratory issues, and in severe cases, fungal infections. It is important to address any mold infestations promptly and take necessary precautions to prevent exposure to high concentrations of mold in indoor environments.

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.

Concentration Camps : A Very Short Introduction
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 genocides in Bosnia and Rwanda.Over the course of the twentieth century they have become defining symbols of humankind's lowest point and basest acts.In this Very Short Introduction, 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.ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area.These pocket-sized books are the perfect way to get ahead in a new subject quickly.Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.

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.

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.

When does a substance have a high concentration and when does a substance have a low concentration?
A substance has a high concentration when there is a large amount of it present in a given volume or area. Conversely, a substance has a low concentration when there is a small amount of it present in a given volume or area. Concentration is a measure of the amount of a substance in a given space, and it can be affected by factors such as diffusion, chemical reactions, and physical barriers.

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.
