Postdoctoral Fellowship
A postdoctoral fellow, postdoctoral researcher, or simply postdoc, is a person professionally conducting research after the completion of their doctoral studies (typically a PhD). The ultimate goal of a postdoctoral research position is to pursue additional research, training, or teaching in order to have better skills to pursue a career in academia, research, or any other field. Postdocs often, but not always, have a temporary academic appointment, sometimes in preparation for an academic faculty position. They continue their studies or carry out research and further increase expertise in a specialist subject, including integrating a team and acquiring novel skills and research methods. Postdoctoral research is often considered essential while advancing the scholarly mission of the host institution; it is expected to produce relevant publications in peer-reviewed academic journals or conferences. In some countries, postdoctoral research may lead to further formal qualificati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Watford, England
Watford () is a town and borough in Hertfordshire, England, 15 miles northwest of Central London, on the River Colne. Initially a small market town, the Grand Junction Canal encouraged the construction of paper-making mills, print works, and breweries. While industry has declined in Watford, its location near London and transport links has attracted several companies to site their headquarters in the town. Cassiobury Park is a public park that was once the manor estate of the Earls of Essex. The town developed next to the River Colne on land belonging to St Albans Abbey. In the 12th century, a charter was granted allowing a market, and the building of St Mary's Church began. The town grew partly due to travellers going to Berkhamsted Castle and the royal palace at Kings Langley. A mansion was built at Cassiobury in the 16th century. This was partly rebuilt in the 17th century and another country house was built at The Grove. The Grand Junction Canal in 1798 and the Lo ...

Khaki University
Khaki University (initially Khaki College or University of Vimy Ridge) was a Canadian overseas educational institution set up and managed by the general staff of the Canadian Expeditionary Force (CEF) in Britain 1917–19 during the First World War. The system, named for the khaki-coloured uniforms of the CEF, was set up by the efforts of Henry Marshall Tory and Edmund Henry Oliver and was supported by the Young Men's Christian Association (YMCA). This university with makeshift colleges mainly in central England provided education on a range of subjects to more than 50,000 soldiers and the certificates given were accepted by Canadian universities. The term was used again for Canadian educational programs for veterans from 1945–46 after the Second World War. History The scheme for education of Canadian army soldiers serving in Europe during the First World War evolved from classes conducted by army chaplains. They noted the need for books and courses and to provide vocationa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geneva Conventions
upright=1.15, Original document in single pages, 1864 The Geneva Conventions are four treaties, and three additional protocols, that establish international legal standards for humanitarian treatment in war. The singular term ''Geneva Convention'' usually denotes the agreements of 1949, negotiated in the aftermath of the Second World War (1939–1945), which updated the terms of the two 1929 treaties and added two new conventions. The Geneva Conventions extensively define the basic rights of wartime prisoners (civilians and military personnel), established protections for the wounded and sick, and provided protections for the civilians in and around a war-zone; moreover, the Geneva Convention also defines the rights and protections afforded to non-combatants. The treaties of 1949 were ratified, in their entirety or with reservations, by 196 countries. The Geneva Conventions concern only prisoners and non-combatants in war; they do not address the use of weapons of war, whic ...

Courseulles-sur-Mer
Courseulles-sur-Mer (, ), commonly known as ''Courseulles'', is a commune in the Calvados department, Normandy, northwestern France. Until 1957, the town's name was simply ''Courseulles''. It lies 3 km west of Bernières-sur-Mer and 18 km north of Caen. It is a popular tourist destination not only with locals but also with international visitors who come to tour the Normandy landing beaches. The population of the town can reach 15,000 people in the summer months owing to the numerous summer homes, owned for the most part by Parisians. The town is split in two by the river Seulles.

D-Day
The Normandy landings were the landing operations and associated airborne operations on Tuesday, 6 June 1944 of the Allied invasion of Normandy in Operation Overlord during World War II. Codenamed Operation Neptune and often referred to as D-Day, it was the largest seaborne invasion in history. The operation began the liberation of France (and later western Europe) and laid the foundations of the Allied victory on the Western Front. Planning for the operation began in 1943. In the months leading up to the invasion, the Allies conducted a substantial military deception, codenamed Operation Bodyguard, to mislead the Germans as to the date and location of the main Allied landings. The weather on D-Day was far from ideal, and the operation had to be delayed 24 hours; a further postponement would have meant a delay of at least two weeks, as the invasion planners had requirements for the phase of the moon, the tides, and the time of day that meant only a few days each month were d ...

Dyestuff
A dye is a colored substance that chemically bonds to the substrate to which it is being applied. This distinguishes dyes from pigments which do not chemically bind to the material they color. Dye is generally applied in an aqueous solution and may require a mordant to improve the fastness of the dye on the fiber. There are two broad categories of dyes: natural and synthetic; Natural dyes are dyes extracted from plants, Insects, or minerals. The majority of natural dyes are vegetable dyes derived from plant sources such as roots, berries, bark, leaves, and wood, as well as other biological sources like fungi. Synthetic dyes are also referred to as "coal tar dyes" because they are derived from substances that, until recently, could only be extracted from coal tar. A synthetic dye consists of a chromophore and an auxochrome added to a benzene derivative. Both dyes and pigments are colored, because they absorb only some wavelengths of visible light. Dyes are usually soluble in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mustard Gas
Mustard gas or sulfur mustard is a chemical compound belonging to a family of cytotoxic and blister agents known as mustard agents. The name ''mustard gas'' is technically incorrect: the substance, when dispersed, is often not actually a gas, but is instead in the form of a fine mist of liquid droplets.https://www.acs.org/content/dam/acsorg/education/resources/highschool/chemmatters/gc-mustard-gas-personal-safety-and-natl-security.pdf Mustard gases form blisters on exposed skin and in the lungs, often resulting in prolonged illness ending in death. The active ingredient in typical mustard gas is the organosulfur compound bis(2-chloroethyl) sulfide. In the wider sense, compounds with the structural element are known as ''sulfur mustards'' and ''nitrogen mustards'', respectively. Such compounds are potent alkylating agents, which can interfere with several biological processes. History as chemical weapons As a chemical weapon, mustard gas was first used in World War I, and has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
