Abstract: The research of plastic deformation of metals attaches great importance to stacking fault energy (SFE). In this paper, we derive the expressions of four types (I1, I2, E and T2) of basal plane SFEs of hcp-Ti within the framework of the Ising model. Based on this model, alloying effects on the stacking fault energy (SFE) of

Abstract: The concept of the coherence length of the neutron is explored. The generally accepteddefinition of a Gaussian wave packet based on the method of the beam preparation, andthe singular de Broglie's wave packet are considered. Possible ways of measuring thecoherence length are discussed.

Abstract: The first eight terms in the Riemann hypothesis is analysed as harmonics with certain ratios to the ground level. The ratios were chosen from acoustic. To obtain the best fit, terms 5 and 7 was assumed to interact in a beat.

Abstract: Propagation and static distribution of light on noncircular orbits are modelled. The space where light embodies is determined with kinematics, such that the perpendicular velocity of the 'material'-space described as a noncircular orbit, is harmonic with amplitude fwre. Light propagation to discrete orbits may occur with a

Abstract: The experimentally found small heating of the neutrons after transmission through thin foils can be explained by violation of energy conservation because of finite energy width of the neutron wave packet. The part of the wave packet subcritically transmitted through a foil has energy distribution higher than that of the inc

Abstract: The ground-state nuclear wave functions, the binding energies, the root mean-square radii and the firstexcited-state energies of the 3H and 4He nuclei are investigated by applying the translation invariant shellmodel and using residual two-body interaction, given by the first author, together with a three-bodyinteraction in

Abstract: For noncircular orbits (nco), with f=3 and f=2, a fractal similar to the Koch-curve is constructed. Attraction and repulsion in a Koch boundary, are suggested, such that the fractal noncircular orbit may attract with all sublevels, or repulse likewise.

Abstract: This article is devoted to the problem of light propagation in a space-time which curvature is due not to massive sources but to the electromagnetic field of the wave itself. Some methodological questions are discussed, such as an isotropy of metric, implementation of the Kalutza-Klein model, topology of space-time, etc
