For example, in duodecimal, 1 / 2 = 0.6, 1 / 3 = 0.4, 1 / 4 = 0.3 and 1 / 6 = 0.2 all terminate; 1 / 5 = 0. 2497 repeats with period length 4, in contrast with the equivalent decimal expansion of 0.2; 1 / 7 = 0. 186A35 has period 6 in duodecimal, just as it does in decimal. If b is an integer base ...
The range of thermodynamic stability of liquid ammonia solutions is very narrow, as the potential for oxidation to dinitrogen, E° (N 2 + 6 [NH 4] + + 6 e − ⇌ 8 NH 3), is only +0.04 V. In practice, both oxidation to dinitrogen and reduction to dihydrogen are slow.
[1] [2] [12] [13] A maximum oxygen partial pressure of 1.4 bar for the active sectors of the dive, and 1.6 bar for decompression stops is recommended by several recreational and technical diving certification agencies for open circuit, [14] and 1.2 bar or 1.3 bar as maximum for the active sectors of a dive on closed-circuit rebreather ...
The 2019 American Community Survey estimated 60.2% of the population was non-Hispanic white, 3.7% black or African American, 15.6% American Indian or Alaska Native, 6.5% Asian, 1.4% Native Hawaiian and other Pacific Islander, 7.5% two or more races, and 7.3% Hispanic or Latin American of any race.
The PLATO system was launched in 1960 at the University of Illinois and subsequently commercially marketed by Control Data Corporation.It offered early forms of social media features with innovations such as Notes, PLATO's message-forum application; TERM-talk, its instant-messaging feature; Talkomatic, perhaps the first online chat room; News Report, a crowdsourced online newspaper, and blog ...
The exact scope and mechanisms of Indian cultural influences on early Philippine polities are still the subject of some debate among Southeast Asian historiographers, [11] [66] but the current scholarly consensus is that there was probably little or no direct trade between India and the Philippines, [11] [66] and Indian cultural traits, such as ...
Probably the best known example of an X-ray binary is the high-mass X-ray binary Cygnus X-1. In Cygnus X-1, the mass of the unseen companion is estimated to be about nine times that of the Sun, [32] far exceeding the Tolman–Oppenheimer–Volkoff limit for the maximum theoretical mass of a neutron star. It is therefore believed to be a black ...
The Global Carbon Budget 2021 concludes that fossil CO 2 emissions rebounded by around +4.8% relative to 2020 emissions – returning to 2019 levels, identifies three major issues for improving reliable accuracy of monitoring, shows that China and India surpassed 2019 levels (by 5.7% and 3.2%) while the EU and the US stayed beneath 2019 levels ...
