The very first statement in the Abstract reveals the author
Mario Bacelar Valente as an ignorant crank.

"A perverted space-time geodesy results from the idea of variable rods
  and clocks, whose length and rates are taken to be affected by the
  gravitational field."

In SR and GR measuring rods always retain their proper length,
and clocks always run at their proper rate. Neither are affected
by gravity or motion.

Didn't you understand that, Laurence?  duh!
