Isobar may refer to: Isobar (meteorology), a line connecting points of equal atmospheric pressure reduced to sea level on the maps. Isobaric process, a process taking place at constant pressure; Isobar (nuclide), one of multiple nuclides with the same mass but with different numbers of protons (or, equivalently, different numbers of neutrons).
The Mattauch isobar rule states that if two adjacent elements on the periodic table have isotopes of the same mass number, at least one of these isobars must be a radionuclide (radioactive). In cases of three isobars of sequential elements where the first and last are stable (this is often the case for even-even nuclides, see above ), branched ...
A laptop computer or notebook computer, also known as a laptop or notebook, is a small, portable personal computer (PC). Laptops typically have a clamshell form factor with a flat-panel screen on the inside of the upper lid and an alphanumeric keyboard and pointing device on the inside of the lower lid.

US keyboards also see use in Indonesia and the Philippines, the former of which uses the same 26-letter alphabet as English. The US keyboard layout has a second Alt key instead of the AltGr key and does not use any dead keys ; this makes it inefficient for all but a handful of languages.
The Arabic spoken in Indonesia is generally used by people of Arabs descent and Islamic students (santri), primarily based on Hadhrami Arabic brought by Arab traders from Hadramaut, Yemen. This language has a unique feature, which is the mixture of vocabulary from Arabic and Indonesian, as well as other regional languages.
The official number of Arab and part-Arab descent in Indonesia was recorded since 19th century. The census of 1870 recorded a total of 12,412 Arab Indonesians (7,495 living in Java and Madura and the rest in other islands). By 1900, the total number of Arabs citizens increased to 27,399, then 44,902 by 1920, and 71,335 by 1930. [5]
The radius of outermost closed isobar (ROCI) is one of the quantities used to determine the size of a tropical cyclone. It is determined by measuring the radii from the center of the storm to its outermost closed isobar in four quadrants, which is then averaged to come up with a scalar value. It generally delimits the outermost extent of a ...
