Bioceramics are widely considered as elective materials for the regeneration of bone tissue,
due to their compositional mimicry with bone inorganic components. However, they are …

Pure hydroxyapatite (HA) is brittle and it cannot be directly used for the load-bearing
biomedical applications. The purpose of this investigation was to develop a new iron …

An experiment to measure the speed of gravitational signals in short distances has been
developed with the goal to study its behaviour as traveling through a medium different from …

This study aims to calculate the predictive number of cycles applied to femoral prostheses
made with ASTM F138 and ASTM F75 alloys. A hip prosthesis is typically subjected to cyclic …

In order to test the effects of hydrothermal and clinically related aging on zirconia, monolithic
disc-shaped samples were milled, sintered and polished from two high translucency …

The objective of this work is to compare the mechanical properties of sintered yttria
tetragonal zirconia polycrystalline (Y-TZP) micro-and nano-particles, and evaluate the …

An experiment to measure the speed of gravitational signals using rotating masses in short
distances has been developed with the intention to study its behaviour when a medium …

In order to investigate the behavior of gravitational signals while travelling through a medium
an experiment was designed, aimed at measuring the speed of these signals over short …

This work shows the optimization process of a quadrupole mass at high-speed rotation
using the finite element modeling (FEM). Such a mass should compose a gravitational …
