Delta ratio. Delta ratio, or " delta-delta ", is a formula that can be used to assess elevated anion gap metabolic acidosis and to evaluate whether a mixed acid–base disorder ( metabolic acidosis) is present. The anion gap (AG) without potassium is calculated first and if a metabolic acidosis is present, results in either a high anion gap ...

Delta-. v. (physics) In general physics, delta-v is a change in velocity. The Greek uppercase letter Δ (delta) is the standard mathematical symbol to represent change in some quantity. Depending on the situation, delta- v can be either a spatial vector (Δ v) or a scalar (Δ v ). In either case it is equal to the acceleration (vector or scalar ...
Delta modulation ( DM or Δ-modulation) is an analog-to-digital and digital-to-analog signal conversion technique used for transmission of voice information where quality is not of primary importance. DM is the simplest form of differential pulse-code modulation (DPCM) where the difference between successive samples is encoded into n-bit data ...
The Selenga River delta in the Russian republic of Buryatia is the largest delta emptying into a body of fresh water, in its case Lake Baikal. Deltas on Mars. Researchers have found a number of examples of deltas that formed in Martian lakes. Finding deltas is a major sign that Mars once had large amounts of water.
