It could stand for 'diluted bee venom' which in recent studies has been shown to reduce neuropathic pain (in lab rats)

The abbreviation 'DBV' can mean many things. Some examples include Data Base Verifier, Decibels relative to one vault, Digital Broadcast Video and Deluxe Beach Villa.
DBV. The English definition of DBV is SPCA. It is trademarked in South Africa to the National Council of Societies for the Prevention of Cruelty to Animals - South Afric

To convert voltage levels to DB you must first specify a reference, then take 20 x log(base 10) of the ratio of the voltage level in question to the reference. For example, if the reference is 1 volt and the signal of interest is 100 volts, then the level in dbV is: 20 x log10 ( 100 / 1 ) = 40 dbV
The airport code for Zagreb Airport is ZAG.
Wind energy turns a windmill (turbine) that turns a magnet that creates electrical energy in a wire. This is Faraday's Generator Law: 0 = dBv/dt + Delx Ev. The windmill creates dBv/dt the change of magnetic field.
Conservation of the Electric Field, E = cB.0 = dEv/dr + Del Es + DelxEv = dBv/dt + Del Es + Del x Ev.
What is dBu? A logarithmic voltage ratio with a reference voltage of V0 = 0.7746 volt ≡ 0 dBu The origin of the index of dBu comes from "u = unloaded" and of dBV is from "V = 1 volt". Some say: The "u" in dBu implies that the load impedance is unspecified, unterminated, and is likely to be high. The home recording level (consumer audio) of −10 dBV means 0.3162 volts, that is −7.78 dBu. The studio recording level (pro audio) of +4 dBu means 1.228 volts.
