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 ...
USS. Delta. (AR-9) USS Delta (AK-29/AR-9) was the lead ship of her class of repair ships in the United States Navy during World War II. She was originally built as the merchant ship SS Hawaiian Packer before her requisition by the U.S. Navy in 1941. Before conversion to a repair ships, Delta briefly served as a U.S. Navy cargo ship .

Delta Cephei (δ Cep, δ Cephei) is a quadruple star system located approximately 887 light-years away in the northern constellation of Cepheus, the King. At this distance, the visual magnitude of the star is diminished by 0.23 as a result of extinction caused by gas and dust along the line of sight. [5]

Delta Crateris (δ Crt, δ Crateris) is a solitary [8] star in the southern constellation of Crater. With an apparent visual magnitude of 3.56, [2] it is the brightest star [9] in this rather dim constellation. It has an annual parallax shift of 17.017 mas as measured from Earth, [1] indicating Delta Crateris lies at a distance of 192 ly from ...
t. e. In mathematical analysis, the Dirac delta function (or δ distribution ), also known as the unit impulse, [1] is a generalized function on the real numbers, whose value is zero everywhere except at zero, and whose integral over the entire real line is equal to one. [2] [3] [4] Since there is no function having this property, modelling the ...
Delta Circini (δ Cir), is a multiple star system located in the constellation Circinus. Delta Circini is also known as HR 5664 , and HD 135240 . The system has a combined apparent visual magnitude of +5.09, and is located at a distance of about 700 pc (2,300ly) from the Sun.
