[11], assuming the dilaton coupling to dark matter and/or dark energy, the magnitude of the time variation of the fine structure constant is estimated. In this paper, we discuss time variations of the proton-electron mass ratio and the fine structure constant in the context of a dilat...

Proton, stable subatomic particle that has a positive charge equal in magnitude to a unit of electron charge and a rest mass of 1.67262 x 10^-27 kg, which is 1,836 times the mass of an electron. Protons, together with electrically neutral particles calle
We have investigated the impact of the I-R54M mutational replacement on the electron transfer and proton pumping activity of P. denitrificans COX. Reduction of the detergent-solubilized I-R54M oxidase by ascorbate at a [cytochrome c]/[[oxidase] molar ratio around 1, shows that full reduction ...
