Thus, the Haldane effect describes the ability of hemoglobin to carry increased amounts of carbon dioxide (CO 2) in the deoxygenated state as opposed to the oxygenated state. Vice versa, it is true that a high concentration of CO 2 facilitates dissociation of oxyhemoglobin, though this is the result of two distinct processes (Bohr effect and ...
The Haldane effect: most carbon dioxide is carried by the blood as bicarbonate, and deoxygenated hemoglobin promotes the production of bicarbonate. Increasing the amount of oxygen in the blood by administering supplemental oxygen reduces the amount of deoxygenated hemoglobin, and thus reduces the capacity of blood to carry carbon dioxide.
Physiographic Map from "Geography of Ohio," published in 1923. During the early 1900s, the study of regional-scale geomorphology was termed "physiography". Physiography later was considered to be a portmanteau of "physical" and "geography", and therefore synonymous with physical geography, and the concept became embroiled in controversy surrounding the appropriate concerns of that discipline.
Brookings effect (atmospheric science) (Curry County, Oregon) (Oregon coast) (Oregon geography) (winds) Brown Willy effect (geography of Cornwall) (mesoscale meteorology) Bruce effect (reproduction) Bullwhip effect (distribution, retailing, and wholesaling) Butterfly effect (chaos theory) (physical phenomena) (stability theory)
Also amphidrome and tidal node. A geographical location where there is little or no tide, i.e. where the tidal amplitude is zero or nearly zero because the height of sea level does not change appreciably over time (meaning there is no high tide or low tide), and around which a tidal crest circulates once per tidal period (approximately every 12 hours). Tidal amplitude increases, though not ...
Haldane's decompression model is a mathematical model for decompression to sea level atmospheric pressure of divers breathing compressed air at ambient pressure that was proposed in 1908 by the Scottish physiologist, John Scott Haldane (2 May 1860 – 14/15 March 1936), [1] who was also famous for intrepid self-experimentation.
John Scott Haldane CH FRS [1] (/ ˈ h ɔː l d eɪ n /; 2 May 1860 – 14/15 March 1936) was a Scottish physician physiologist and philosopher famous for intrepid self-experimentation which led to many important discoveries about the human body and the nature of gases. [2]
Cultural geography is a subfield within human geography.Though the first traces of the study of different nations and cultures on Earth can be dated back to ancient geographers such as Ptolemy or Strabo, cultural geography as academic study firstly emerged as an alternative to the environmental determinist theories of the early 20th century, which had believed that people and societies are ...
