Our experiment to measure the speed of alternating electricity is briefly reported here. It is found that the speed of alternating electricity within the metal wire is not constant, which is depended on the circuit parameters. In most cases, the speed of alternating electricity i...

The mechanism of slow positrons has been discussed in terms of diffusion of positrons at the surface of SiC and trapping in to as-grown and irradiation induced defects. The one dimensional diffusion equation has been solved and the rate equations have been set up to describe the...

This paper determines the dynamic buckling load of a lightly and viscously damped imperfect spherical cap with a step load. The spherical cap is discretized into a pre-buckling symmetric mode and a buckling mode that consists of axisymmetric and non-axisymmetric buckling modes. T...

Bianchi type-IX space-time is considered in the framework of the ƒ(R) theory of gravity when the source of the energy momentum tensor is a perfect fluid. The cosmological model is obtained by using the condition that the expansion scalar (θ) is proportional to the shear scalar (σ...

Aim: To develop a model of matter that will account for electro-gravity. Interacting particles with non-gravitational fields can be seen as clocks whose trajectory is not Minkowsky geodesic. A field, in which each such small enough clock is not geodesic, can be described by a sca...

Pure, Mn+2, and Fe+3- doped hydroxyapatite (HAp) nanoparticles were synthesized by the wet chemical method. Another two samples were prepared by mixing Mn+2 with Cu+2 into HAp (Mn-Cu HAp) and Fe+3 with Co+2 into HAp (Fe-Co HAp). All samples were prepared without change in the sto...

The present paper scrutinizes the principle of quantum determinism, which maintains that the complete information about the initial quantum state of a physical system should determine the system’s quantum state at any other time. As it shown in the paper, assuming the strong expo...
