    The Sutherland–Einstein Hypothesis on the Origin of Magnetic Fields of Astropysical Objects

    No full text
    Abstract: We discuss the theoretical and experimental foundations of the hypothesis on the origin of the magnetic fields of the Earth and other astrophysical objects, put forward in the early twentieth century by Sutherland and later by Einstein. According to this hypothesis, the electric charges of an electron and a proton are slightly different in absolute values, which, due to the rotation of the Earth (or another astronomical object), leads to emergence of a magnetic field. Terrestrial experiments aimed at determining the difference in the electric charges of an electron and a proton are discussed. The Sutherland–Einstein hypothesis is theoretically justified within the framework of two versions of the geometric approach: (1) in a simplified version of the 6-dimensional Kaluza–Klein theory, and (2) in the framework of the 5-dimensional Kaluza theory with scalarism, as well as in the framework of the relational approach. © 2021, Pleiades Publishing, Inc

    On Explanations of Magnetic Fields of Astrophysical Objects in the Geometric and Relational Approaches

    No full text
    The geometric and relational approach to the unified description of gravity and electromagnetism are considered. In the framework of the relational theory, as well as multidimensional geometric models of Kaluza–Klein type, some arguments are invoked in support of Einstein’s hypothesis on a small charge asymmetry of elementary particles and Sutherland’s hypothesis on the origin of the magnetic fields of the Earth, the Sun and other astrophysical objects. According to this hypothesis, effective currents created by bulk and surface charges contribute to the dynamics of the magnetic field of planets. Estimates of this effect for various astrophysical objects are made. © 2018, Pleiades Publishing, Ltd

    Linkage and association analyses of glaucoma related traits in a large pedigree from a Dutch genetically isolated population

    Background: Despite extensive research on the genetic determinants of glaucoma, the genes identified to date explain only a small proportion of cases in the general population. Methods: Genome-wide linkage and association analyses of quantitative traits related to glaucoma were performed: intraocular pressure, size and morphology of the optic disc (individual and combined by method of principal components) and thickness of the retinal nerve fibre layer (RNFL), in a large pedigree from a genetically isolated Dutch population. Results: For the size of the optic disc, the study demonstrated a significant linkage signal (logarithm of odds (LOD)=3.6) at the LRP1B region on chromosome 2q21.2-q22.2 and significant association (p=8.953×10 -12) with the previously reported CDC7/TGFBR3 locus at 1p22. For parameters describing morphology of the optic disc, the study obtain
