Constraining Yukawa gravity from planetary motion in the solar system
(Journal of the Geographical Institute Jovan Cvijic, SASA, 2019)
In this work we used the observed additional perihelion precession in the Solar System, obtained from the observations of planets and spacecrafts, to study the possible existence of Yukawa correction term to the Newtonian ...
Tensile Properties and Fracture Mechanism of In-100 Superalloy in High Temperature Range
(Metallurgical and Materials Engineering, 2017)
Tensile properties and fracture mechanism of a polycrystalline IN-100 superalloy have been investigated in the range from room temperature to 900 degrees C. Optical microscopy (OM) and transmission electron microscopy (TEM) ...
