    THOUGHTS OF COMPARISON OF RESONANCE FREQUENCIES OF CHEMICAL ELEMENTS OF PERIODIC TABLE WITH PERSON’S BIORHYTHMS by V. V. Butukhanov

    Published 2012-09-01
    “…Resonance frequencies of chemical elements of periodic table were obtained for the first time, exact limits of electroencephalogram rhythms were determined, correspondence of ranges (677 — 0,02 Hz) of resonance frequencies of chemical elements with rhythms of brain, heart, breathing and intestines work and. their octaves with limits of frequencies that are resonance with frequency of hydrogen atom radiation was revealed.…”

    Adsorbed Chemical Elements of River Runoff of Solids and Their Role in the Transformation of Dissolved Matter Runoff into the Ocean by Alla V. Savenko, Vitaly S. Savenko

    Published 2022-04-01
    “…A procedure for experimental modeling of sorption–desorption processes in the mixing zone of river and sea waters, which excludes the determination of the absolute concentrations of adsorbed chemical elements, has been proposed. Based on experimental data, quantitative characteristics of the ion-exchange transformation of dissolved matter runoff during the penetration of terrigenous material into the marine environment were obtained. …”
