Superconducting YBa2Cu3O7−x thin films were obtained under high vacuum (10−5 Torr) on substrates of polycrystalline Al2O3 sapphire, SrTiO3, and Si, having zero resistance at 81, 85, 87, and 79 K, respectively. A N2 laser of 3.5 J cm−2 energy density was used for the evaporation. The substrates were heated by a cw single-mode CO2 laser and the annealing was performed by the same laser in O2 atmosphere. Local planar superconducting regions were obtained by focusing the radiation of the cw CO2 laser upon the films. The films were investigated by scanning electron microscope, x-ray microanalysis, and x-ray diffraction.
The influence of the Coriolis inertial force generated by the orbital and spin motions of distant objects on the electromagnetic radiation energies during the exchange of photons between such objects has been considered. A red or blue spectral shift occurrence in a passive observation
mode that is not associated with the Doppler effect or other known effects has also been shown. The relations found are used to calculate the spectral shifts for several nearby stars from our galaxy, as well as the spectral shifts of several galaxies. The results are close to the values currently
observed.
In this paper we show how the velocity of a moving uniform opaque body can be calculated without external references. This is done with the help of photodetectors, which measure the time of arrival of light from a point source to fixed equal distances inside the body. The calculation of the body’s velocity is based on the postulates of the special theory of relativity that space is homogeneous, isotropic and the speed of light in vacuum is an invariant constant with a certain value independent of the velocity of the radiation source.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
