Zero-point radiation, inertia and gravitation

In this paper it is shown that the forces which resist the acceleration of the mass of the electron, $m_e$, arising from the Compton effect, the Klein-Nishima-Kann formula for its differential cross section and the transversal Doppler effect when the electron moves in a straight line coincide, with $\vare<1,16\times10^{-4}$, with the force required to propel me with the same acceleration, if the radius of the electron is equal to its classical radius and if the forces which rise from the interaction of the electron and zero-point radiation are equal to those deriving from the electrostatic repulsion of the charge of the electron against itself (Poincare's tensions). The equations worked in this paper show that there is no difference between inertial mass and gravitational mass and may be used to determine the value of the gravitational constant.
