  • BARYON CHARGE (baryon number) (B), one of internal performances of baryons. For all baryons B = +1, and for their antiparticles B =-1 (for remaining fundamental particles B = 0). The algebraic sum of the baryon charges, logging in particles, is saved at all interactions.
  • BARYONS (from grech. barys - heavy), "heavy" fundamental particles with a half-integral spin and mass, not smaller mass of a proton; participate in all known fundamental interactions. Nucleones, superprotons concern to baryons and many from t. n. Resonances.
  • BARISAN (Barisan), mountains on a southwest about. Sumatra, in Indonesia. Length ok. 650 kms, an altitude up to 3805 m (a burning mountain of Kerintji). Evergreen tropical forests.
  • BARITE (heavy spar), mineral of a class of sulphates, BaSO4. Impurity{additives} Sr (sometimes up to 20 %), Ca, Pb. Hardness 3-3,5; firmness of 4,3-4,5 g / sm3. By origin hydrothermal and hypergenic. Main{basic} ore Ba; a filling agent in rubber and a paper industry; an adulterant at boring, etc.
  • BARITO (Barito), the river on about. Kalimantan, in Indonesia. Ok. 880 kms, the area of basin ok. 100 thousand êì2. Runs in JAvanskoe m., derivating delta. It is navigable from verhovjev. In delta - seaport Bandjarmasin.
  • BARITOSIS, the pneumokoniosi stipulated by influence of a dust, keeping a barium and his{its} connections.
  • BAROMETRIC SYSTEM, range of the under or a supertension in an atmosphere (napr., a cyclone and an anticyclone) with characteristic distribution of an atmospheric pressure, and accordingly and a wind.
  • BAROMETRIC FIELD, spacing of an atmospheric pressure. It is defined by system of equipressure surfaces - isobaric surfaces, and above ground - system of equipressure lines - isobars.
  • BARIUM OXYHYDROXIDE, Ba (OH) 2, colourless crystals. A water solution of a barium of oxyhydroxide - baryta water. It is applied as reagent on a sulphate and carbonates - ions, a component of lubrications, to clearing vegetative and animal oils, removal of a sulphate - ion from industrial solutions.
  • BARIUM CARBONATE, BaCO3, colourless crystals. In water it is practically insoluble. Will derivate a mineral witherite. Apply in manufacture of an optical glass, enamels, glazes, a red brick.
  • BARIUM the SULPHATE, BaSO4, colourless crystals. In water it is practically insoluble. Will derivate a mineral barite. The paper filler, a component of lithopone, a contrast means at a roentgenoscopy.
  • BARK (goll. bark), a marine sailing vessel (3-5 spar trees) with fore-and-aft sails on an aftermast (mizzen mast) and direct on remaining.
  • BARK Peter Lvovich (1869-1937), the Russian statesman. In 1907-11 managing director Volzhsko-Kamskogo of a business bank. In 1914-17 Minister of Finance. With 1918 in emigration.
  • BARK (ital. barca), river cargo non-propelled flat-bottomed wooden a vessel of a light-weight construction without a control surface.
  • BARCAROLE (ital. barcarola, from barca - a boat), a song of the venetian gondoliers; mild, pumping motion of a melody, lyrical character are typical. By many composers are built vocal and instrumentalje the plays realizing features of a national barcarole.
  • PADDLE WHEEL (niderl. barkas), 1) a self-propelled vessel of the small dimensions for transportations to a port... 2) In a VTR the rowing boat from 14-22 paddles.
  • BARKGAUZEN (Barkhausen) Genrih George (1881-1956), german physics and the electrical engineer. Has discovered the effect called as his{its} name. Has constructed (1919) generator of continuous microwave oscillations.
  • BARKGAUZENA EFFECT, step change of a magnetization of ferromagnetic substance at continuous change of environmental conditions, napr., a magnetic field. It is stipulated by a domain structure. G.Barkgauzenom (1919) is open{discovered}.
  • BARKENTINE (English barkentine) (schooner - bark), a marine sailing vessel (3-5 spar trees) with goosewings on a forward{front} spar tree (foremast) and skew on remaining.
