The development of a strong speedrunning community is considered to have originated with the 1993 computer game Doom. [2] [3] [4] The game retained the "par time" mechanic from Wolfenstein and included a feature that allowed players to record and play back gameplay using files called demos (also known as game replays).
European Speedrunner Assembly. European Speedrunner Assembly (abbreviated to ESA), formerly European Speedster Assembly, is a semi-annual video game speedrunning charity marathon held in Sweden. Held since 2012, the events have raised hundreds of thousands of dollars for several charities. [1][2] The two flagship events of the European ...
The most important sodium compounds are table salt (NaCl), soda ash (Na 2 CO 3), baking soda (NaHCO 3), caustic soda (NaOH), sodium nitrate (NaNO 3), di- and tri-sodium phosphates, sodium thiosulfate (Na 2 S 2 O 3 ·5H 2 O), and borax (Na 2 B 4 O 7 ·10H 2 O). [24] In compounds, sodium is usually ionically bonded to water and anions and is ...
Exercise-associated hyponatremia (EAH) is a fluid-electrolyte disorder caused by a decrease in sodium levels (hyponatremia) during or up to 24 hours after prolonged physical activity. [1] This disorder can develop when marathon runners or endurance event athletes drink more fluid, usually water or sports drinks, than their kidneys can excrete. [2]
The most important sodium compounds are table salt (Na Cl), soda ash (Na 2 CO 3), baking soda (Na HCO 3), caustic soda (NaOH), sodium nitrate (Na NO 3), di- and tri- sodium phosphates, sodium thiosulfate (Na 2 S 2 O 3 ·5H 2 O), and borax (Na 2 B 4 O 7 ·10H 2 O). [7] In compounds, sodium is usually ionically bonded to water and anions and is ...
Sodium periodate is an inorganic salt, composed of a sodium cation and the periodate anion.It may also be regarded as the sodium salt of periodic acid.Like many periodates, it can exist in two different forms: sodium metaperiodate (formula NaIO 4) and sodium orthoperiodate (normally Na 2 H 3 IO 6, but sometimes the fully reacted salt Na 5 IO 6).
The family of sodium channels has 9 known members, with amino acid identity >50% in the trans-membrane segments and extracellular loop regions. A standardized nomenclature for sodium channels is currently used and is maintained by the IUPHAR. [8] The proteins of these channels are named Na v 1.1 through Na v 1.9.
Disodium helide. [Na]. [Na]. [He] Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Disodium helide[2] (Na 2 He) is a compound of helium and sodium that is stable at high pressures above 113 gigapascals (1,130,000 bar). It was first predicted [3] using the USPEX crystal structure ...
