A residue's properties will influence interactions with other residues and the overall chemical properties of the protein it resides in. One might say, "This protein consists of 118 amino acid residues" or "The histidine residue is considered to be basic because it contains an imidazole ring."
Pesticide residue, refers to the pesticides that may remain on or in food after they are applied to food crops; Petroleum residue, the heavier fractions of crude oil that fail to vaporize in an oil refinery; Residue (chemistry), materials remaining after a physical separation process, or by-products of a chemical reaction
The definition of a residue can be generalized to arbitrary Riemann surfaces. Suppose ω {\displaystyle \omega } is a 1-form on a Riemann surface. Let ω {\displaystyle \omega } be meromorphic at some point x {\displaystyle x} , so that we may write ω {\displaystyle \omega } in local coordinates as f ( z ) d z {\displaystyle f(z)\;dz} .
The term “pesticide residue” includes residues from unknown or unavoidable sources (e.g. environmental) as well as known uses of the chemical. The definition of a residue for compliance with maximum residue limits (MRLs) is that combination of the pesticide and its metabolites, derivatives and related compounds to which the MRL applies. [4]
The impact of residue placement (buried by tillage or left on the surface in zero tillage) on nutrient cycling and efficiency is under study. [ citation needed ] Thus, the practice of calculating the fertilizer equivalent value of the nutrients in crop residue is a reasonable guide to estimating the partial value of crop residues.
It is also known as a residual estate or simply residue. The will may identify the taker of the residuary estate through a residuary clause or residuary bequest . The person identified in such a clause is called the residuary taker , residuary beneficiary , residuary legatee , or residuary devisee . [ 2 ]
Gunshot residue (GSR), also known as cartridge discharge residue (CDR), gunfire residue (GFR), or firearm discharge residue (FDR), consists of all of the particles that are expelled from the muzzle of a gun following the discharge of a bullet.
Note that, because of the definition of the sample mean, the sum of the residuals within a random sample is necessarily zero, and thus the residuals are necessarily not independent. The statistical errors, on the other hand, are independent, and their sum within the random sample is almost surely not zero.
