Pacific Northwest
The Pacific Northwest (sometimes Cascadia, or simply abbreviated as PNW) is a geographic region in western North America bounded by its coastal waters of the Pacific Ocean to the west and, loosely, by the Rocky Mountains to the east. Though no official boundary exists, the most common conception includes the U.S. states of Oregon, Washington (state), Washington, and Idaho, and the Canadian province of British Columbia. Some broader conceptions reach north into Alaska and Yukon, south into northern California, and east into western Montana. Other conceptions may be limited to the coastal areas west of the Cascade Mountains, Cascade and Coast Mountains, Coast mountains. The variety of definitions can be attributed to partially overlapping commonalities of the region's history, culture, geography, society, ecosystems, and other factors. The Northwest Coast is the coastal region of the Pacific Northwest, and the Northwest Plateau (also commonly known as "British Columbia Interi ...

Samuel Thomas Von Sömmerring
Samuel Thomas von Sömmerring (28 January 1755 – 2 March 1830) was a German physician, anatomist, anthropologist, paleontologist and inventor. Sömmerring discovered the macula in the retina of the human eye. His investigations on the brain and the nervous system, on the sensory organs, on the embryo and its malformations, on the structure of the lungs, etc., made him one of the most important German anatomists. Career Sömmerring was born in Thorn (Toruń), Royal Prussia (a province of the Crown of Poland) as the ninth child of the physician Johann Thomas Sömmerring. In 1774 he completed his education in Thorn and began to study medicine at the University of Göttingen. He visited Petrus Camper lecturing at the University in Franeker. He became a professor of anatomy at the Collegium Carolinum (housed in the Ottoneum, now a Natural History Museum) in Kassel and, beginning in 1784, at the University of Mainz. There he was for five years the dean of the medical faculty. Aft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Journal Of Neurology
The ''Journal of Neurology'' is a peer-reviewed medical journal covering research on diseases of the nervous system In biology, the nervous system is the highly complex part of an animal that coordinates its actions and sensory information by transmitting signals to and from different parts of its body. The nervous system detects environmental changes .... It was established in 1891 as the ''Deutsche Zeitschrift für Nervenheilkunde'' and was renamed to ''Zeitschrift für Neurologie'' in 1947. It obtained its current title in 1971. Publication was interrupted in 1945 and 1946.

Migraine
Migraine (, ) is a common neurological disorder characterized by recurrent headaches. Typically, the associated headache affects one side of the head, is pulsating in nature, may be moderate to severe in intensity, and could last from a few hours to three days. Non-headache symptoms may include nausea, vomiting, and photophobia, sensitivity to light, hyperacusis, sound, or Osmophobia, smell. The pain is generally made worse by physical activity during an attack,as PDF although regular physical exercise may prevent future attacks. Up to one-third of people affected have Aura (symptom), aura: typically, it is a short period of visual disturbance that signals that the headache will soon occur. Occasionally, aura can occur with little or no headache follow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Samuel-Auguste Tissot
Samuel Auguste André David Tissot (; 20 March 1728 – 13 June 1797) was a notable 18th-century Swiss physician. Life A well-reputed Calvinist Protestant neurologist, physician, professor and Vatican adviser, Tissot practiced in the Swiss city of Lausanne. He wrote on the diseases of the poor, on masturbation, on the diseases of men of letters and of rich people, and nervous diseases. He devoted an 83-page chapter to the study of migraine in his ''Traité des nerfs et de leurs maladies'' (Treatise on the nerves and nervous disorders). He used his own observations and the existing medical treatises of the day. His work is considered by modern doctors as a basis for "future generations of doctors." He is also recognized as "the classical authority on migraine."K. Karbowski, (1986, April). Samuel Auguste Tissot His research on migraine, ''Journal of Neurology'', Volume 233, Number 2, ISSN 0340-5354 (Print) 1432-1459 (Online), Pages 123-125 ''L'Onanisme'' In 1760, he published '' ...

John Hunter (surgeon)
John Hunter (13 February 1728 – 16 October 1793) was a British surgeon, one of the most distinguished scientists and surgeons of his day. He was an early advocate of careful observation and scientific method in medicine. He was a teacher of, and collaborator with, Edward Jenner, pioneer of the smallpox vaccine. He is alleged to have paid for the stolen body of Charles Byrne, and proceeded to study and exhibit it against the deceased's explicit wishes. His wife, Anne Hunter (''née'' Home), was a poet, some of whose poems were set to music by Joseph Haydn. He learned anatomy by assisting his elder brother William with dissections in William's anatomy school in Central London, starting in 1748, and quickly became an expert in anatomy. He spent some years as an Army surgeon, worked with the dentist James Spence conducting tooth transplants, and in 1764 set up his own anatomy school in London. He built up a collection of living animals whose skeletons and other organs he prepa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oceanography
Oceanography (), also known as oceanology and ocean science, is the scientific study of the oceans. It is an Earth science, which covers a wide range of topics, including ecosystem dynamics; ocean currents, waves, and geophysical fluid dynamics; plate tectonics and the geology of the sea floor; and fluxes of various chemical substances and physical properties within the ocean and across its boundaries. These diverse topics reflect multiple disciplines that oceanographers utilize to glean further knowledge of the world ocean, including astronomy, biology, chemistry, climatology, geography, geology, hydrology, meteorology and physics. Paleoceanography studies the history of the oceans in the geologic past. An oceanographer is a person who studies many matters concerned with oceans, including marine geology, physics, chemistry and biology. History Early history Humans first acquired knowledge of the waves and currents of the seas and oceans in pre-historic times. Observations ...

Agulhas Current
The Agulhas Current () is the western boundary current of the southwest Indian Ocean. It flows south along the east coast of Africa from 27°S to 40°S. It is narrow, swift and strong. It is suggested that it is the largest western boundary current in the world ocean, with an estimated net transport of 70 sverdrups (70 million cubic metres per second), as western boundary currents at comparable latitudes transport less — Brazil Current (16.2 Sv), Gulf Stream (34 Sv), Kuroshio (42 Sv). Physical properties The sources of the Agulhas Current are the East Madagascar Current (25 Sv), the Mozambique Current (5 Sv) and a recirculated part of the south-west Indian subgyre south of Madagascar (35 Sv). The net transport of the Agulhas Current is estimated as 100 Sv. The flow of the Agulhas Current is directed by the topography. The current follows the continental shelf from Maputo to the tip of the Agulhas Bank (250 km south of Cape Agulhas). Here the momentum of the current ...

James Rennell
Major James Rennell, (3 December 1742 – 29 March 1830) was an English geographer, historian and a pioneer of oceanography. Rennell produced some of the first accurate maps of Bengal at one inch to five miles as well as accurate outlines of India and served as Surveyor General of Bengal. Rennell has been called the ''Father'' ''of'' ''Oceanography''. In 1830, he was one of the founders of the Royal Geographical Society in London. Early life Rennell was born at Upcot near Chudleigh in Devon. His father, John Rennell, an officer in the Royal Artillery, was killed in action in the Low Countries in July 1747 during the War of the Austrian Succession. His mother Anne subsequently married Mr Elliott, a widower with children of his own and unable to care for additional ones, leading to Rennell being brought up by a guardian, the Rev. Gilbert Burrington, vicar of Chudleigh. The ancient paternal Devonshire family name was formerly spelt Reynell and was of French origin. Rennell entere ...
