The symbol (uppercase) should be used with prefix symbols (thus, mTorr and millitorr are correct, but mtorr and milliTorr are not). The torr is sometimes incorrectly denoted by the symbol "T", which is the SI symbol for the tesla, the unit measuring the strength of a magnetic field. Although frequently encountered, the alternative spelling "Tor ...
The reason for the discovery of this phenomenon was an accident: the aerologists working at the marine Hydrometeorology stations and watercraft drew attention to the strange pain that a person experiences when approaching the surface of a standard meteorological probe (a balloon filled with hydrogen).
Microbarometers are sensitive barometers that can measure air pressure with high precision. Microbarometers typically have a resolution of microbars (μbar) or pascals (Pa), while ordinary barometers [1] can only resolve in hectopascals (hPa) or millibars (mbar).

A barn (symbol: b) is a metric unit of area equal to 10 −28 m 2 (100 fm 2).This is equivalent to a square that is 10 −14 m (10 fm) each side, or a circle of diameter approximately 1.128 × 10 −14 m (11.28 fm).
An analog barometer. A barometer is a scientific instrument that is used to measure air pressure in a certain environment. Pressure tendency can forecast short term changes in the weather.
For example, a miniature quadrupole ion trap mass analyzers, such as cylindrical ion trap, linear ion trap, rectilinear ion trap), can operate at several mTorr in contrast to 10 −5 Torr or less for other analyzers and it is able to perform MS/MS in a single device with minimum size of electronics system. Nevertheless, as the size gets smaller ...
mTOR signaling pathway. The PI3K/AKT/mTOR pathway is an intracellular signaling pathway important in regulating the cell cycle.Therefore, it is directly related to cellular quiescence, proliferation, cancer, and longevity.
