Looking through the Mass-to-Charge Ratio: Past, Present and Future Perspectives
, 2021 The mass spectrometry (MS) provides the mass-to-charge ratios of atoms, molecules, stable/metastable complexes, and their fragments. I have taken a long journey with MS to address outstanding issues and problems by experiments and theory and gain ...

On the evolution of the black hole: spheroid mass ratio [PDF]
Monthly Notices of the Royal Astronomical Society, 2006 AbstractWe present the results of a study which uses the 3CRR sample of radio‐loud active galactic nuclei (AGN) to investigate the evolution of the black‐hole:spheroid relation in the most massive early‐type galaxies from 0 < z < 2. Radioloud unification is exploited to obtain virial (line‐width) black‐hole mass estimates from the 3CRR quasars ...

Modelling Rocket System Performance Parameters
Academy Journal of Science and Engineering, 2022 What distinguishes the rocket system from airbreathing engines is that the rocket carries its own propellants, fuel and oxidants. The modern rocket was originally developed for ballistic missiles.

Ratio of Nucleon Mass and Electron Mass [PDF]
Nature, 1960 WITH reference to the experimental value 1840 for the ratio of nucleon and electron mass, mentioned by Prof. A. J. Rutgers in Nature of September 19, p. 1959, it may be noted that the ratio of proton mass and electron mass is given by the exponential equation:
