Sadlermiut Whaling
The Sadlermiut (also called Sagdlirmiut, or Sallirmiut in modern Inuktitut spelling, from ''Sadlerk'' now ''Salliq'', the Inuktitut name for the settlement of Coral Harbour, Nunavut) were an Inuit group living in near isolation mainly on and around Coats Island, Walrus Island, and Southampton Island in Hudson Bay. They survived into the early 20th century and were thought by some to have been the last remnants of the Dorset culture as they had preserved a culture and dialect distinct from the mainland Inuit. Despite their culture and local traditions seeming to show combined elements of both the Dorset and Thule societies, genetic studies show no Dorset admixture and prove a sole Inuit ancestry leading many to conclude the cultural difference may be entirely due to their isolation from the mainland Inuit. Research published in 2015 found that the Sadlermiut were genetically Thule who had somehow acquired Dorset cultural features, such as stone technology. It remains a mystery how t ...

Genetic Admixture
Genetic admixture occurs when previously isolated populations interbreed resulting in a population that is descended from multiple sources. It can occur between species, such as with hybrids, or within species, such as when geographically distant individuals migrate to new regions. It results in gene pool that is a mix of the source populations. Examples Climatic cycles facilitate genetic admixture in cold periods and genetic diversification in warm periods. Natural flooding can cause genetic admixture within populations of migrating fish species. Genetic admixture may have an important role for the success of populations that colonise a new area and interbreed with individuals of native populations. Mapping Admixture mapping is a method of gene mapping that uses a population of mixed ancestry (an admixed population) to find the genetic loci that contribute to differences in diseases or other phenotypes found between the different ancestral populations. The method is best app ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Typhus
Typhus, also known as typhus fever, is a group of infectious diseases that include epidemic typhus, scrub typhus, and murine typhus. Common symptoms include fever, headache, and a rash. Typically these begin one to two weeks after exposure. The diseases are caused by specific types of bacterial infection. Epidemic typhus is caused by '' Rickettsia prowazekii'' spread by body lice, scrub typhus is caused by '' Orientia tsutsugamushi'' spread by chiggers, and murine typhus is caused by '' Rickettsia typhi'' spread by fleas. Vaccines have been developed, but none is commercially available. Prevention is achieved by reducing exposure to the organisms that spread the disease. Treatment is with the antibiotic doxycycline. Epidemic typhus generally occurs in outbreaks when poor sanitary conditions and crowding are present. While once common, it is now rare. Scrub typhus occurs in Southeast Asia, Japan, and northern Australia. Murine typhus occurs in tropical and subtropi ...

Typhoid Fever
Typhoid fever, also known simply as typhoid, is a disease caused by '' Salmonella enterica'' serotype Typhi bacteria, also called ''Salmonella'' Typhi. Symptoms vary from mild to severe, and usually begin six to 30 days after exposure. Often there is a gradual onset of a high fever over several days. This is commonly accompanied by weakness, abdominal pain, constipation, headaches, and mild vomiting. Some people develop a skin rash with rose colored spots. In severe cases, people may experience confusion. Without treatment, symptoms may last weeks or months. Diarrhea may be severe, but is uncommon. Other people may carry it without being affected, but are still contagious. Typhoid fever is a type of enteric fever, along with paratyphoid fever. ''Salmonella enterica'' Typhi is believed to infect and replicate only within humans. Typhoid is caused by the bacterium ''Salmonella enterica'' subsp. ''enterica'' serovar Typhi growing in the intestines, Peyer's patches, mesen ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Influenza
Influenza, commonly known as the flu, is an infectious disease caused by influenza viruses. Symptoms range from mild to severe and often include fever, runny nose, sore throat, muscle pain, headache, coughing, and fatigue. These symptoms begin one to four (typically two) days after exposure to the virus and last for about two to eight days. Diarrhea and vomiting can occur, particularly in children. Influenza may progress to pneumonia from the virus or a subsequent bacterial infection. Other complications include acute respiratory distress syndrome, meningitis, encephalitis, and worsening of pre-existing health problems such as asthma and cardiovascular disease. There are four types of influenza virus: types A, B, C, and D. Aquatic birds are the primary source of influenza A virus (IAV), which is also widespread in various mammals, including humans and pigs. Influenza B virus (IBV) and influenza C virus (ICV) primarily infect humans, and influenza D virus (IDV) i ...

Library And Archives Canada
Library and Archives Canada (LAC; ) is the federal institution tasked with acquiring, preserving, and providing accessibility to the documentary heritage of Canada. The national archive and library is the 16th largest library in the world. The LAC reports to the Parliament of Canada through the Minister of Canadian Heritage. LAC traces its origins to the Dominion Archives, formed in 1872, and the National Library of Canada, formed in 1953. The former was later renamed as the Public Archives of Canada in 1912, and the National Archives of Canada in 1987. In 2004, the National Archives of Canada and the National Library of Canada were merged to form Library and Archives Canada. History Predecessors The Dominion Archives was founded in 1872 as a division within the Department of Agriculture tasked with acquiring and transcribing documents related to Canadian history. In 1912, the division was transformed into an autonomous organization, Public Archives of Canada, with the n ...

United Kingdom Of Great Britain And Ireland
The United Kingdom of Great Britain and Ireland was the union of the Kingdom of Great Britain and the Kingdom of Ireland into one sovereign state, established by the Acts of Union 1800, Acts of Union in 1801. It continued in this form until 1927, when it evolved into the United Kingdom, United Kingdom of Great Britain and Northern Ireland, after the Irish Free State gained a degree of independence in 1922. It was commonly known as Great Britain, Britain or England. Economic history of the United Kingdom, Rapid industrialisation that began in the decades prior to the state's formation continued up until the mid-19th century. The Great Famine (Ireland), Great Irish Famine, exacerbated by government inaction in the mid-19th century, led to Societal collapse, demographic collapse in much of Ireland and increased calls for Land Acts (Ireland), Irish land reform. The 19th century was an era of Industrial Revolution, and growth of trade and finance, in which Britain largely dominate ...

Indigenous Peoples Of The Americas
In the Americas, Indigenous peoples comprise the two continents' pre-Columbian inhabitants, as well as the ethnic groups that identify with them in the 15th century, as well as the ethnic groups that identify with the pre-Columbian population of the Americas as such. These populations exhibit significant diversity; some Indigenous peoples were historically hunter-gatherers, while others practiced agriculture and aquaculture. Various Indigenous societies developed complex social structures, including pre-contact monumental architecture, organized city, cities, city-states, chiefdoms, state (polity), states, monarchy, kingdoms, republics, confederation, confederacies, and empires. These societies possessed varying levels of knowledge in fields such as Pre-Columbian engineering in the Americas, engineering, Pre-Columbian architecture, architecture, mathematics, astronomy, History of writing, writing, physics, medicine, Pre-Columbian agriculture, agriculture, irrigation, geology, minin ...

Whaling
Whaling is the hunting of whales for their products such as meat and blubber, which can be turned into a type of oil that was important in the Industrial Revolution. Whaling was practiced as an organized industry as early as 875 AD. By the 16th century, it had become the principal industry in the Basque coastal regions of Spain and France. The whaling industry spread throughout the world and became very profitable in terms of trade and resources. Some regions of the world's oceans, along the animals' migration routes, had a particularly dense whale population and became targets for large concentrations of whaling ships, and the industry continued to grow well into the 20th century. The depletion of some whale species to near extinction led to the banning of whaling in many countries by 1969 and to an international cessation of whaling as an industry in the late 1980s. Archaeological evidence suggests the earliest known forms of whaling date to at least 3000 BC, practiced by the ...

George Francis Lyon
George Francis Lyon (23 January 1796 – 8 October 1832) was an English naval officer and explorer of Africa and the Arctic. While not having a particularly distinguished career, he is remembered for the entertaining journals he kept and for the pencil drawings he completed in the Arctic; this information was useful to later expeditions. Early life He was born in Chichester, the elder son of Lieutenant Colonel George Lyon of the 11th Light Dragoons and Louisa Alexandrina Hart. She was in turn the second daughter of Sir William Neville Hart and Elizabeth Aspinwall. He was educated at Burney's Academy in Gosport, Hampshire. Naval career After joining the Royal Navy he was entered on the books of at Spithead in 1808 before going to sea aboard . Niger River In 1818, he was sent along with Joseph Ritchie by Sir John Barrow to find the course of the Niger River and the location of Timbuktu. The expedition was underfunded, lacked support and because the ideas of Joh ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
