چکیده

In a recent paper of D.S. Hajdukovic (Astrophys. Space Sci. 343, 505, 2013), it is hypothetically claimed that “the quantum vacuum induces a retrograde precession of the perihelion and the Newton’s force of gravity might be accompanied with a tiny radial force that is a signature of the quantum vacuum”. However, the present paper argues that the quantum vacuum cannot really be the causal origin of the extra-gravitational effects and the additional radial acceleration and force are in fact a sort of the gravitational induction due to the relative motion of the test-body in the vicinity of the principal gravitational source.

Study of Solar Magnetic and Gravitational Energies Through the Virial Theorem

Virial theorem is important for understanding stellar structures. It produces an interesting connection between magnetic and gravitational energies. Using the general form of the virial theorem including the magnetic field (toroidal magnetic field), we may explain the solar dynamo model in relation to variations of the magnetic and gravitational energies. We emphasize the role of the gravitatio...

In this paper, the effect of compressive viscosity on the slow mode oscillation of solar corona loops is studied. The coronal loops medium are considered in low beta condition, uniform magnetic field in the presence of gravitational stratification and temperature gradient. Two-dimensional Magneto-Hydro-Dynamics (MHD) equations are perturbed about the equilibrium and thenthese equations are lin...

Experimental Investigation of the Thermal Performance of Vacuum Tube Solar Collectors (VTSC) Using Alumina Nanofluids

The enhancement of the thermal performance of Vacuum Tube Solar Collectors (VTSC) was studied by using alumina nanofluid as working fluid. VTSC is a simple and commonly utilized type of collector. This study established the heat transfer experimental model of all glass VTSCs used in a forced-circulation solar water heating system using alumina nanofluid as base fluid. Al2O3 (with an average par...

Gravitational waves are considered in thermal vacuum state. The amplitude and spectral energy density of gravitational waves are found enhanced in thermal vacuum state compared to its zero temperature counterpart. Therefore, the allowed amount of enhancement depends on the upper bound of WMAP-5 and WMAP-7 for the amplitude and spectral energy density of gravitational waves. The enhancement of ...

Development of a Pilot Plant Solar Liquid Desiccant Air Conditioner for the Northern Region of Iran

In a 10-ton capacity pilot plant solar liquid desiccant air conditioner (LDAC) developed, dehumidification of the outside air is achieved through a honeycomb packed-bed heat and mass exchanger, using lithium chloride solution as the desiccant. The dry air obtained from the dehumidification process is evaporative cooled inside a cooling pad and directed into the conditioned space. The dilute sol...
