In this paper the dynamic of a droplet on a surface with a hole is investigated under gravitational effect by using lattice Boltzmann method. Incompressible two-phase flow with high density ratio proposed by Lee is considered. Cahn’s theory is used to observe the wettability of the surface in contact with liquid and gas phases. Several parameters such as contact angle, surface tension and gravi...

Gravitational Thomas Precession ( GTP ) is the name given to Thomas Precession when the acceleration is caused by a gravitational force field. The GTP gives a negative contribution of 7 · 163 arcsec/century for the anomalous perihelion advance of Mercury’s orbit.This effect seems to be of some concern for the General Relativity. PACS: 04.80Cc ; 96.30Dz

The restoration of spontaneous symmetry breaking for a scalar field theory for an accelerated observer is discussed by the one-loop effective potential calculation and by considering the effective potential for composite operators. Above a critical acceleration, corresponding to the critical restoration temperature, , for a Minkowski observer by Unruh relation, i.e. c T 2π c c a T  , the symme...

During transportation by ambulance, the inertial acceleration acts on a patient when an ambulance decelerates or turns a corner. Such acceleration often gives a supine patient physical stress such as blood pressure variation and body sway, which results in pain or a feeling of discomfort. To reduce this undesirable effect of the acceleration, the actively-controlled bed, which controls a postur...

As early as in 1907, Einstein showed that the light speed must be larger at spacetime points with higher gravitational potential. This idea is used here to present a relativistic version of a recent model which explains the acceleration of the Pioneer 10 spaceship as the effect of a universal adiabatic acceleration of light. This phenomenon would have the same observational signature as an acce...
