A variety of factors determine the chemical stability of a lubricant, including concentrations of catalysts such as copper. Sulphur content The sulphur content of lubricants is an important property to consider as the chemical element can fast-track corrosion. That said, sulphur ...
The meaning of PHYSICAL PROPERTY is a property (as color, hardness, boiling point) of matter not involving in its manifestation a chemical change.
Functional diversity rather than species richness is critical for the understanding of ecological patterns and processes. This study aimed to develop novel integrated analytical strategies for the functional characterization of fish diversity based on th
