Mass spectrometry (MS)-based shotgun proteomics is a fast and relatively easy method for protein identification. A shotgun proteomics experiment typically proceeds by tandem MS (MS/MS) analysis of ...

The relative atomic masses of elements are proportional measures. For example, the Ar for helium is 4.0, and the A r for carbon is 12.0. This means that carbon atoms have three times the mass of ...

Chlorine naturally exists as two isotopes, \(_{17}^{35}\textrm{Cl}\) (chlorine-35) and \(_{17}^{37}\textrm{Cl}\) (chlorine-37). The abundance of chlorine-35 is 75% ...

Researchers believe they have found which species has the largest testicles in relation to body weight on the planet -- and why. One of the researchers said, "We couldn't believe the size of these ...

ABSTRACT.This article describes a new grid for the mass–radius relation of three-layer exoplanets within the mass range of 0.1–100 M⊕0.1–100 M⊕. The three layers are: Fe (ϵϵ-phase of iron), ...
