A number of possible experiments on a rotating disk is discussed with a view to verifying the special theory of relativity. Concepts discussed include observers proper time, physically measurable distances, frequencies, and so on.
Show AbstractA class of cosmologlcal models with a spinning fluid is investigated. An anisotropic generalization of the de Sitter model with torsion, a generalization of the anisotropic model with cosmological constant, and a stationary model with rotation without loss of causality are obtained.
Show AbstractIt is shown that the generalized Osborn relation together with the correct commutation of the collective time with momentum, energy, and collective coordinate of the system ensure that the previously found expressions for the coordinates of the center of a set of events are unique.
Show AbstractThe standard Weinberg-Salam-Glashow model is used to calculate the probability of the decay of the neutrino into an electron and the W-boson in a plane-wave field (crossed field + wave). An analysis of a partial expansion of the total decay probability has led to results that describe the photoproduction of $W^+e^-$ pairs by relativistic neutrinos in a crossed field.
Show AbstractAn analysis is given of the effect due to the additional neutral vector boson predicted by the 7-dimensional theory of gravielectroweak interactions. The scattering of a muon neutrino by a muon, in which the additional neutral current appears at both high and relatively low energies of the colliding particles, is examined as a special case.
Show AbstractThe nonlinear equations of motion of the Weinberg-Salam W-bosons in an ultrastrong magnetic field are investigated. The resulting topologically stable solutions can be interpreted as the condensate states of W-bosons in a magnetic field.
Show AbstractThe first results are reported on hadron intensity recorded at a depth of 81-110 cm of lead in an X-ray emulsion chamber. The intensity of the cascades within the chamber is calculated on the assumption that charmed particles are created with high probability in hadron interactions.
Show AbstractAn experimental study is reported of the compensation of thermal refraction by positive lenses mounted at entry to the medium with thermal nonlinearity. The results are generalized to the case of semi-infinite media.
Show AbstractAdsorption on glass in different water solutions of dyes has been measured. The amount of adsorption was found to be correlated with the associative power of the materials.
Show AbstractA description is given of a universal laser spectrometer for non-linear-optics diagnostics of semiconductor surfaces. The system is fully automatic and is controled by the DVK-2 computer.
Show AbstractCorrelation times and activation energies have been determined for the rotational motions of individual molecular groups in HOPDOB. They are compared with analogous quantities for translational motion, deduced from optical experiments.
Show AbstractA study is reported of anomalies in the permittivity of ${N(CH_3)_4}_2ZnCl_4$ (TMATC-Zn) crystals in the region of the commensurate-incommensurate phase transition point. It is reported that the Curie-Weiss law is valid for permittivity in the incommensurate phase and that there is an anomalous temperature hysteresis of the phase transition point and permittivity.
Show AbstractThe effect of nonuniform avalanche injection of electrons from Si into $SiO_2$ on the threshold avalanche voltage, the generation of surface states, and surface generation has been investigated.
Show AbstractIt is shown that the coercive force of a ferrite-garnet film is a temperature-sensitive parameter because of the temperature dependence of the anisotropy field and the energy of the walls. The "period" and "amplitude" of the magnetic potential profile of moving domain walls undergo a change near the compensation point, which is due to the change in the magnetostatic interaction between the domains.
Show AbstractThe model employed is that of a "polymer chain in an array of obstacles." The effective potential representing the average effect of ambient polymer molecules on a given branch is determined. The stress relaxation time in a melt of branched chains is found.
Show AbstractA nonintrusive method is proposed for the determination of the surface resistance and mean free time of carriers in a thin layer of a doped semiconductor deposited on a high-resistance substrate whose thickness is insufficient for the observation of the plasma minimum. The method is based on measurement of the infrared transmission of silicon wafers in the wavelength range 20-130 μm.
Show AbstractA determination is reported of the parameters of the Mittag-Leffler expansion that result in the optimum expansion for the reciprocal distance that converges more rapidly tban the universal expansion by the factor $e^{20/l_1^2}$, where $l_1$ is the distance between the nearest mountains and the point of observation. The expansion converges more rapidly at a given point than the Laplace series.
Show AbstractIt is emphasized that there must a covariant relationship between the metric of flat space and the metric of curved space in the theory of graviation "on a flat background." It is shown that this distinguishes the relativistic theory of gravitation from the general theory of relativity "on a flat background."
Show AbstractThe Stark broadening of the $H_\beta$ line of hydrogen was used to determine the concentration of electrons in a stimulated microwave discharge channel in nitrogen as a function of the gas pressure. At atmospheric pressure, the concentration of electrons in the nitrogen channel was found to be $(1\div 2) \cdot 10^{15}$ cm$^{-3}$.
Show AbstractThe metallic model was used to carry out an exact evaluation of the off-diagonal components of the conductivity and polarizability tensors of the benzene molecule, which are essential for the determination of the Faraday effect.
Show AbstractA technique for the phase calibration of an intensity meter is discussed. It is shown that the phase uncertainty can be determined from measurements of the distribution of the active and reactive intensities of the acoustic field.
Show AbstractThe harmonic of temperature oscillation due to the propagation of temperature waves in a liquid were observed in the region in which the thermophysical properties of the medium were highly temperature dependent (near the critical point).
Show AbstractAn experimental study was carried out of absorption by a spherical sample of a nickel ferrite single crystal at frequencies in the range 3.4-?.8 GHz. Resonance oscillations due to the uniform electric field predicted by previous theoretical calculations were recorded for the first time.
