Seek animal foods as your primary source of choline, but augment with plant based sources as desired. Cruciferous Veggies Veggies from this group, including cauliflower, cabbage, bok choy and broccoli, boast around 65 mg of choline per cup cooked.
Since its normally easier to conduct measurements of voltage rather than power, some prefer using the voltage of a system as a reference. As a result, the dBu unit of measure is used many times in audio systems vice dBm. The dBu unit is calculated by: A = 20log(V2/V1).In this formula, the reference level is 0.77 volts rms. In most audio equipment, the normal dBu line level is 4 dBu.ince its normally easier to conduct measurements of voltage rather than power, some prefer using the voltage of a system as a reference.

BTU is a unit of measurement for energy. One BTU is equal to the amount of energy used to raise the temperature of one pound of water one degree Fahrenheit.n a heat pump or furnace, the BTU number refers to the heat output of the particular unit. The higher the number the more heat the unit can produce. Air conditioners are a little different. The BTU number on cooling equipment refers to the amount of energy used to remove the heat from the air.
