  • Urban Viaducts Influence on the Vertical Concentrations of Particulate Matters

    Urban Viaducts Influence on the Vertical Concentrations of Particulate Matters Jing Xiao, Hong-di He, Rong Gao Logistics Research Center, Shanghai Maritime University, Shanghai 201306, China Due to the increase of private vehicles in China cities, high-level pollution is often detected in urban street canyons. The study selected Jinlu building as the research object and used FLUCK985 particle counter to collect the particles concentration at different heights, at the same time, combined with meteorological to study the vertical variation characteristics. Finally,…

  • Masses of celestial bodies

    Masses of celestial bodies A. S. Orlov, S. A. Orlov SPGU, PGU The calculation of the masses of celestial bodies based on the theory of vortex gravity, cosmology and cosmogony is proposed. The actual values of the masses of celestial bodies are two orders of magnitude greater than the generally accepted values. Keywords: Vortex gravity, cosmology and cosmogony. Heavenly mechanics.

  • Gravitation Flat Power Field

    Gravitation – Flat Power Field S.A. Orlov A new principle of origin and the nature of the action of gravity forces are proposed. Forces of universal attraction have plane-symmetrical directions. On this basis, it becomes possible to reconsider certain regularities in natural science. The new principle of gravitation will allow to explain physical paradoxes, to improve methods of scientific research and some technological processes. Keywords: Theory vortex gravitation, cosmology and cosmogony. Celestial mechanics
