We verify some assertions in the prequel to this paper, in which certain functions which are referred to as proximity functions were introduced in order to study Dirichlet-type approximations in normed divisible groups and similar groups that enjoy a form of divisibility, for ins...

The mass in Einstein’s energy-mass equivalence equation has two possible interpretations, whether it is limited to the invariant mass, or it applies to all energy. This paper argues that all of the energy (kg m2 s−2) has a mass (kg: a degree of weight and inertial resistance). Th...

The formula for the gravitational force inside a spherical body is derived, as well as for the Newtonian force of attraction between bodies from the standpoint of the gravitons’ model. The parameters of the graviton field are estimated, including its energy density, energy flux a...

We studied the microwave absorption of multi-walled carbon nanotubes (MWCNTs)-epoxy composites over a continuous frequency range in R-band (26.5 – 40 GHz). The outer diameters (OD) of the MWCNTs were in the 10 – 20 nm range. We measured and analyzed the microstructures, dielectri...
