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
In naming residues, the word acid is replaced with residue. [5] 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 ...
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.
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.
In a solution, all of the ingredients are uniformly distributed at a molecular level and no residue remains. A solvent-solute mixture consists of a single phase with all solute molecules occurring as solvates (solvent-solute complexes), as opposed to separate continuous phases as in suspensions, emulsions and other types of non-solution mixtures.
This replaces the proportion of cellulose fibres from trees, meaning that these trees do not need to be cut down for paper production, but can be left to absorb CO₂ and convert it into oxygen. Made from agricultural waste, this paper and board meets high quality standards and is available as printing paper, among other things. [ 32 ]
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 Australian meaning of this term is malo lactic fermentation MLF, as distinct from primary fermentation, the conversion of sugar to alcohol. Skin contact Another term to describe maceration.l Solera system A process used to systematically blend various vintages of Sherry. Sorbic acid
