The base "Roman fraction" is S, indicating 1 ⁄ 2. The use of S (as in VIIS to indicate 7 1 ⁄ 2) is attested in some ancient inscriptions [45] and also in the now rare apothecaries' system (usually in the form SS): [44] but while Roman numerals for whole numbers are essentially decimal, S does not correspond to 5 ⁄ 10, as one might expect ...
where nnnn is the code point in decimal form, and hhhh is the code point in hexadecimal form. The x must be lowercase in XML documents. The nnnn or hhhh may be any number of digits and may include leading zeros. The hhhh may mix uppercase and lowercase, though uppercase is the usual style.
One radian is defined as the angle at the center of a circle in a plane that subtends an arc whose length equals the radius of the circle. [6] More generally, the magnitude in radians of a subtended angle is equal to the ratio of the arc length to the radius of the circle; that is, =, where θ is the magnitude in radians of the subtended angle, s is arc length, and r is radius.
This fraction was in favor of protons initially, primarily because the lower mass of the proton favored their production. As the Universe expanded, it cooled. Free neutrons and protons are less stable than helium nuclei, and the protons and neutrons had a strong energetic reason to form helium-4. However, forming helium-4 requires the ...
Airbus's publicity has stressed the comfort and space of the A380 cabin, [220] and advertised onboard relaxation areas such as bars, beauty salons, duty-free shops, and restaurants. [ 221 ] [ 222 ] Proposed amenities resembled those installed on earlier airliners, particularly 1970s wide-body jets, [ 223 ] which largely gave way to regular ...
[400] [398] Prior to 2010, each person could register as a member of only one race, by default that of his or her father; therefore, mixed-race persons were solely grouped under their father's race in government censuses. From 2010 onward, people may register using a multi-racial classification, in which they may choose one primary race and one ...
Lower power levels at a receiver reduce the chance of successfully receiving a transmission. Low levels can be caused by at least three basic reasons: low transmit level, for example Wi-Fi power levels; far-away transmitter, such as 3G more than 5 miles (8.0 km) away or TV more than 31 miles (50 km) away; and obstruction between the transmitter ...
Worldwide shipments of personal computers surpassed the 100-million mark in 1999, growing to 113.5 million units from 93.3 million units in 1998. [76] In 1999, Asia had 14.1 million units shipped. [77] As of June 2008, the number of personal computers in use worldwide hit one billion, [78] while another billion is expected to be reached by 2014.
