He claimed that in a symmetric universe wherein only two symmetrical spheres exist, the two spheres are two distinct objects even though they have all their properties in common. [ 13 ] Black argues that even relational properties (properties specifying distances between objects in space-time) fail to distinguish two identical objects in a ...
Two-dimensional gel electrophoresis, abbreviated as 2-DE or 2-D electrophoresis, is a form of gel electrophoresis commonly used to analyze proteins. Mixtures of proteins are separated by two properties in two dimensions on 2D gels. 2-DE was first independently introduced by O'Farrell [ 1 ] and Klose [ 2 ] in 1975.
Every mineral has a different electrical resistance which can be observed by passing an electric current through the mineral and measuring the resistance. Relief; Appearance of roughness, texture or thickness in optical mineralogy. This relief is caused by variations in refractive index of minerals. Fracture; Type of fracture and fracture ...
In general two objects with identical properties, other than position at an instance in time, may be distinguished as two objects and may not occupy the same space at the same time (excluding component objects). An object's identity may be tracked using the continuity of the change in its boundary over time.
SPM – Scanning probe microscopy; SRM-CE/MS – Selected-reaction-monitoring capillary-electrophoresis mass-spectrometry; SSNMR – Solid-state nuclear magnetic resonance; Stark spectroscopy; STED – Stimulated emission depletion microscopy; STEM – Scanning transmission electron microscopy; STM – Scanning tunneling microscopy
A more efficient analysis of copolymer molecular mass and composition is possible using GPC combined with a triple-detection system comprising multi-angle light scattering, UV absorption and differential refractometry, if the copolymer is composed of two base polymers that provide different responses to UV and/or refractive index.

DNA barcoding is a method of species identification using a short section of DNA from a specific gene or genes. The premise of DNA barcoding is that by comparison with a reference library of such DNA sections (also called "sequences"), an individual sequence can be used to uniquely identify an organism to species, just as a supermarket scanner uses the familiar black stripes of the UPC barcode ...
