It can cause nausea and diarrhea, especially in high doses or after long-term use. It might also pose a risk of ulcers in high doses. As a topical treatment, it can cause skin irritation. Caution is advised when turmeric is taken by people known to have gallstones; consult your health care provider first.
Gain is the ratio between the magnitude of output and input signals. Gain controls on an amplifier are basically just small potentiometers (variable resistors) or volume controls, that allow you to adjust the incoming signal to the amplifier.
A letter following the dB indicates the reference antenna: * Gain specified in decibels-isotropic (dBi) indicates how the antenna performs as compared to an isotropic radiator. An isotropic radiator is a theoretical antenna that radiates equally in all directions (including up and down).* Gain specified in decibels-dipole (dBd) indicates how the antenna performs as compared to a dipole antenna. A dipole antenna has a 2.14 dBi gain over an isotropic radiator.Any dBi figure may be converted to dBd by subtracting 2.14. Be careful when comparing antenna gains that both values are in the same unit. Whip antenna gains are often specified in dBi, while other antennas are often specified in dBd. dipole antenna has a 2.14 dBi gain over an isotropic radiator.
