![]() In 1949, Edward and Philip successfully extracted the adrenocorticotropic hormone cortisone from animals and elucidated its structure and biological effects. Undoubtedly, immunosuppressive agents have achieved great progress and success in the treatment of these diseases, thus further demonstrating the great research and development prospects of immunosuppressive agents. ![]() Many are of the Canadian sector of the front during the so-called "Last Hundred Days" of the war (August 1918 - November 1918) with some produced by the Canadian Corps topo section.Īerial photograph coverage is scattered over much of the area of conflict in France and Belgium but there is a high concentration of photography in areas around Ypres, Meteren, Messines, Lille and Wytschaete with some coverage around areas such as Albert, Cambrai, the Hindenburg line, Canal du Nord and Cuinchy brick stacks.Immunosuppressive agents are a class of drugs that inhibit the abnormal immune response of the body and suppress the proliferation and function of cells related to the immune response (macrophages such as T cells and B cells), thereby reducing the antibody immune response, and are now mainly used in organ transplantation anti-rejection reactions and autoimmune diseases. The bulk of the collection is from the latter part of the war in the years 19 when map production had increased dramatically. The majority of the collection is made up of 1:10,000 scale trench maps, 1:20,000 scale artillery maps, and 1:40,000 scale officer's planning maps. They range in scale from very detailed operations maps used for trench raids to very broad overview maps used to show the entire front. Most of the maps in this collection were produced by the British Ordnance Survey for the Allied forces, although a few German, French and other maps purchased privately by officers exist within the collection. The history of geography throughout the British Empire in all its aspects is represented in this collection, which also focuses on environmental history, exploration, colonization and decolonization, anthropology, law, climate science, gender studies and cartography. ![]() McMaster University Library has just acquired permanent access to the digitized archives of the Royal Geographical Society (1478 to 1953). This digital database contains a range of primary sources, searchable manuscripts, correspondence, reports, conference papers, proceedings, maps, charts, atlases, photographs, surveys, data and ephemera produced by the researchers and members of RGS. You may also be interested in.a series of lectures on historical cartography by McMaster University Library's Map Specialist, Gord Beck. High resolution, scanned images of the maps are available to be viewed online and freely downloaded for non-commercial purposes. Original maps may be viewed in the Library's Archives and Research Collections Division. The collection is an indispensible teaching resource providing students with the opportunity to examine cartography as not just a tool for navigation, but as a work of art, an expression of power, a cultural worldview, and a chronicle of scientific advancement. The oldest map in the collectionwas published in Johannes Reger's 1486 edition of Ptolemy's Cosmographia. The historical and rare maps in the Lloyd Reeds Map Collection span the years between 1486 and the end of the Cold War in 1990.
