The main{basic} transactionses on an electrodynamics, study x-ray and cathode rays, seismology. Has developed (1899) method of definition of speed of particles of cathode rays. Irrespective of Dzh. Dzh. Thomson was discovered with an electron and has defined{determined} his{its} charge (experience Viherta). In 1897 has placed{installed} existence of a nucleus of the Earth.
  • REEL (dzhek), a bird of a set drof. Length ok. 60 see. On a head a crest, on a neck a collar from the lengthy feathers. The Sowing dwells{lives} in deserts and semideserts. Africa and Asia, including from deserts Zakaspijskih up to Tuva. It is small, it is guarded.

  • The SWIRLING-TYPE FURNACE, the chamber furnace with vortex motion of gases in the combustion chamber, an achievable special arrangement of torches.
  • VORTEX MOTION, flow of fluid (or gas) at which their small volumes move{migrate} not only bodily, but also are spun about some instantaneous axis (napr., waterspouts, funnels in water, etc.).
  • The PERIPHERAL PUMP, 1) a vacuum pump in which rarefaction forms lengthwise axis a vortex flow of a compressed air or a gaseous steam driving on tangent to the chamber of whirling. A residual pressure up to 0,7 Pa. 2) the Rotodynamic pump of abrasion in which the liquid receives power as a result of its{her} whirling by the rotated driving wheel and moves{migrates} over rims of the driving wheel in a tangential direction. Feed up to 0,01 m3 / with, a head up to 100 m, efficiency up to 45 %.
  • EDDY CURRENTS (eddy current), selfcontained inductive currents in solid explorers which arise under action of the vortical electric field generated by a variable magnetic field. Eddy currents result in loss of the electric power on heating of an explorer in which they have arisen; for reduction of this loss magnetic circuits of machines and apparatuses alternating-current produce from isolated steel plates.
  • VIHREKAMERNYJ the ENGINE, the diesel, which each cylinder is paired to the whirlpool chamber where fuel is premixed by a vortex of incoming air. Vihrekamernye engines are defined by small sensitivity to fuel grade, but a heightened specific consumption of it{him}.
