AbstractAbstract

[en] The model according to which space subreality and time subreality are created during Big Bang is introduced. The first one is centrosymmetrical, the second anticentrosymmetrical. One to another they are transformed by mutual ''replacement'' space and time. Such subrealities are not antisubrealities and their elementary particles (appeared through Big Bang) are not able to annihilate completely because of symmetry conditions. This leads to the appearance of condensed matter. The model of two subrealities gives the possibility to explain without ''parity violation'' any physical phenomena. Four macroscopic rules of symmetry [scale, corkscrew, gyroscope and right (left) hand] reflect four fundamental interactions of our reality. (author). 10 refs, 16 figs

AbstractAbstract

[en] It is shown that the variety of the known stable elementary particles can be presented as a variety of conserved quantities and their combinations. Energy, momentum and angular momentum are used as conserved quantities. To aid the description, elementary particles and conserved quantities are represented by geometrical symbols (polar vector, axial vector, scalar, pseudoscalar, etc.). The possibility of finding new elementary particles is indicated as well as the peculiarities of the properties of those already known (existence of intrinsic momentum, its spatial quantatization, etc.). The paper discusses also the specifics of the particle-antiparticle concept and some questions related to the problem of invariance. (author)

AbstractAbstract

[en] The term 'improper' ferroelectrics has recently come to be used for ferroelectrics in which the spontaneous polarization Ps is not transition parameter. From the standpoint of symmetry therefore, the new (polar) symmetry group is no longer the highest common sub-group of the crystal symmetry and the spontaneous polarization symmetry (polar vector symmetry group infinity mm). The concept of an improper ferroelectric has therefore been revised to include transitions from polar to polar groups. It is shown that in the general cases where other parameters are permissible, the problem has to be solved using the symmetry of directions. The present analysis on the bases of irreducible representation of polar crystals establishes all the possible cases where spontaneous polarization is accompanied by spontaneous magnetisation, optical activity and more complex phenomena. The symmetry changes and the polarization configurations in Gd(MoO

_{4})_{3}, boracites, (NH_{4})_{2}BeF_{4}, alkali trihydrogen selenite family have been discussed in the light of the extended concept of an 'improper' ferroelectric. (author)Source

AbstractAbstract

[en] Various systems of co-ordinates are considered describing motion in space (xsub(s)tsub(s)), motion in time (xsub(t)tsub(t)), motion referred on a parity basis to space and time (xsub(s)tsub(t), xsub(t)tsub(s)), motion referred to an absolute origin x

_{0}sup(*)t_{0}sup(*), and also a system describing self-motion of space-time, xsub(v0)tsub(α0). The transformation of the co-ordinate x and time t with the transition from one inertial system of co-ordinates to another is considered. It is shown that all inertial systems xsub(s)tsub(s) of the special theory of relativity (moving with different velocities v) move in a full-parity system with the same velocity, v_{0}=cc_{0}, where c is the velocity of light when its propagation is described in space, and c_{0}the velocity of light when its propagation is described in time (abs c=1/abs c_{0}), whereby the reason for the uniformity of physical laws in all inertial systems is established. The concept of an invariant of motion related to a full-parity system, V^{2}(the dimension of the square of velocity) is introduced, and it is shown that this invariant is conserved in inertial movements. It is established that the special theory of relativity is a particular case of the generalized description of motion based on two limiting quantities - the velocity of light, c, and the maximum 'velocity' of time change, αsub(max)=1/c_{0}- and that it considers only motion in space. It is shown that the 'distortion' of length and time scales is a consequence of describing motion in non-parity co-ordinates systems. (author)Primary Subject

AbstractAbstract

[en] The concept of an inverse-motion interval in space Tsub(s) (with the dimensions of time) is introduced and it is shown that the square of this interval is conserved in all inertial motions. In the motion-in-time description, a certain instant of time t=0 is taken as the origin and the concepts of direct and inverse motion are defined with respect to this instant. A graphical representation is given of motion in the co-ordinate systems xsub(s)tsub(s) (the system used in the special theory of relativity), xsub(t)tsub(t) (direct motion in time) and also in the parity systems xsub(s)tsub(t) and xsub(t)tsub(s). A geometrical demonstration is given of the statement that in the parity systems xsub(s)tsub(t) and xsub(t)tsub(s) all inertial motions take place with the same velocity v

_{0}= √(cc_{0}). A consequence of this is that the 'distortion' of the spatial and temporal scales arising in the description of motion (for example, the slowing down of time for motion in space) does not occur in parity reference systems. It is assumed that the origin and the expansion of the Universe are a result of a Big Bang at a point with co-ordinates x_{0}sup(*)t_{0}sup(*). The motion of non-interacting galaxies is considered. The characteristics of the relative motion of galaxies in space as observed from the Earth are analysed. The motion of the galaxies that were formed earlier than our own is described in the co-ordinates xsub(s)tsub(t) (intervals S and T); for those that appeared later the co-ordinates are xsub(t)tsub(s) (intervals Tsub(s) and Ssub(t)). It is shown that the motion of galaxies that are far from Earth and close to the absolute origin must be described by Hubble's law. The characteristics of galaxy trajectories [R=f(t)] as observed from Earth are discussed; one of these corresponds to the Lemaitre model but is related not to a slowing down of the expansion of the Universe but to the conditions under which this expansion is studiedPrimary Subject

AbstractAbstract

[en] Adopting a single approach, the author discusses earlier papers published by him on generalization of the special theory of relativity to cover the case of motion at low velocities. This generalization is based on introduction of the concept of motion in time. For motion of this type the space-time relationships are derived by making the following substitution in the well-known relationships of the special theory of relativity: xsub(s)→tsub(t), tsub(s)→xsub(t), vsub(s)→αsub(t)(αsub(t)=1/vsub(t)), c→αsub(max). In motion in time the interval T

^{2}=α^{2}sub(max) Δx^{2}-Δt^{2}is conserved. It is demonstrated that in the parity frames of reference xsub(s)tsub(t) and xsub(t)tsub(s) all inertial motions occur at the same velocity v_{0}, the velocity of self-motion. It is further shown that, as observed from the Earth, the galaxies arising before the galaxy to which the Earth belongs should appear to be approaching ('violet'), while those arising after the occurrence of our own galaxy should appear to be receding ('red'), in accordance with Hubble's law. On this basis statements to the effect that the Universe is expanding are regarded as unfounded. Motion in time and motion in space are treated as extreme states described by maximally high and maximally low densities of matter rho. The formation of the Universe is considered as the process of unification of these extreme states, leading to the conserved mean density rho_{0}. Local deviations from the mean density at rho< rho_{0}lead to the creation of unobservable 'temporal' regions through gravitation (rho=rhosub(max)). Regions with rho>rho_{0}are transformed into observable 'spatial' regions with density rho=rhosub(min). As they develop the regions of various types may change from one state to another. It is concluded that the Universe is stationary - it is neither expanding nor contracting. (author)Primary Subject

AbstractAbstract

[en] The author considers a model of reality for which he postulates the existence of a minimum speed of propagation of interactions c

_{0}identical for all inertial reference frames. The characteristic features of motion in a system of this kind are found at small velocities of motion. Space-time relationships are given for a model of this kind, including the time interval and modified Lorentz relationships obtained by the substitution v→1/v,x→t,t→x,c→1/c_{0}. Motion in the model considered is treated as motion in time. The relationships obtained for the model with c_{0}non-equal 0 are combined with the space-time relationships of the special theory of relativity (maximum speed of propagation of interactions, cc_{0}finite, motion in space). For the combined model it proves possible to select a reference frame described by the velocity v_{0}= root square (cc_{0}). It is assumed that the velocity v_{0}determines the natural relationship between space and time expressed in their 'self-motion'. For the system describing 'self-motion' (the system x_{0}t_{0}) the 'divergence of space' with respect to the fixed value of the co-ordinate x is determined by the velocity c, while the 'divergence of time' with respect to the fixed moment t is determined by the 'velocity' αsub(max)=1/c_{0}. It is demonstrated that in the latter case the minimum velocity c_{0}corresponds to the speed of light. The author gives equations for the transformation of the length and time scales and the space (x) and time (t) co-ordinates in the combined model for motion in time, motion in space and motion with respect to the system x_{0}t_{0}. The possibility of using the proposed generalization to describe our own reality is considered, and it is shown that the co-ordinate and time transformations cited in the paper at certain values of c, c_{0}and v are reduced to Galilean transformations.

AbstractAbstract

[en] The authors discuss the latest advances in the use of the NMR technique for studying domain structure and domain walls in ferromagnets, and examine the theoretical fundamentals of wall NMR spectra for the case of uniaxial ferromagnets. Within the framework of existing theory, they analyse experimental data on wall NMR spectra. Particular attention is given to recent results of NMR studies on

^{57}Fe nuclei in the domain walls of rare-earth orthoferrite crystals. It is demonstrated that in some cases the NMR technique can yield completely new and otherwise unobtainable data on the properties of domain walls. Examples are given to show how the NMR method can be applied to the study of spin rotation within walls, temperature re-arrangement of wall types, wall polarization in a magnetic field, temperature effects due to wall spin waves, dynamic properties of domain walls as related to crystal defects, hysteresis characteristics of the domain structure, and certain other properties associated with the domain structure.
