Bop it is considered the first considerable style of the modern jazz.

MILLETGRASS, pine forest on sandy and stony soils; sometimes with an impurity{additive} of a birch, almost without a underwood.

MILLETGRASS (an armour. Borum), In, a chemical element of III group of a periodic system, atomic number 5, atomic weight 10,811. The title from pozdnelat. borax - a bore. Colourless, adamantine crystals (because of impurity{additives} serovato-black); firmness 2,31 - 2,35 g / sm3, tïë 2074 °S. At routine temperature it is chemical inert. In a nature meets primarily by the way borates. Apply as a component corrosion-resistant and high-temperature alloys, composites (including boroplastikov), alloys to control devices of nuclear reactors, and also for borating.

MILLETGRASS (Bohr) Nils Henrik David (1885-1962), danish physics, one of creators of modern physics. The founder (1920) and the chief of Institute of theoretical physics in Copenhagen (Institute Nilsa of Bohr); the creator of world scientific school; foreign member AN the USSR (1929). In 1943-45 worked in the USA. Has created the theory of atom in which basis{fundamentals} have lain epicyclic atomic model, quantum submissions and offered him{it} of Bohr postulates. The important activities under the theory of metals, theories of an atomic kernel and nuclear reactions. Transactionses on philosophy of natural sciences. The active participant of extirpation against nuclear threat. The Nobel Prize (1922).

MILLETGRASS Oge (r. 1922), danish physics. Son N.Bora. One of writers of the generalized model of an atomic kernel. The Nobel Prize (1975, together with B.Mottelsonom and Dzh. Rejnuoterom).

MILLETGRASS Harald (1887-1951), danish mathematician. Brother N.Bora. Transactionses under the theory of almost-periodic functions.

MILLETGRASS BLACK, the emergency tax in the Novgorod ground from ground and crafts. It was nominated in 2-nd floor. 14 - 15 centuries grand duke Moscow for payment of a tribute to Golden Horde.

MILLETGRASS (ital. bora, from grech. boreas - boreal wind), the aboriginal strong (up to 40 - 60 ms) a cool wind in some maritime areas where low-level mountain hrebty adjoin on a warm sea (napr., on Adriatic a shore of Slovenia bliz Trieste, on Black Sea a shore in area of Novorossisk). It downcast on downslopes, it is routinely marked in the winter.

MILLETGRASS CARBIDE, B4C, black crystals; it is decomposed above 2450 °S. On hardness concedes only to diamond and white graphite. Abrasive and a grinding material, a neutron absorber in nuclear reactors, a semiconductive material.

MILLETGRASS the MAGNETON, see in an item. A magneton.

MILLETGRASS NITRIDE, BN, crystals. White updating is applied to obtaining high refractories, stratifils, as a semiconductive material, a dry film lubrication for bearings, a neutron absorber in nuclear reactors. Black updating (borazon) with tïë 3200 °S on hardness is close to diamond; it is used as abrasive.

MILLETGRASS POSTULATES, the main{basic} assumptions in a quantum theory of atom of N.Bora (1913 : 1)) Existence of some the stationary states of atom conforming to defined values of his{its} internal energy E... 2) Conditions of frequencies? Radiances at transition of atom from one stationary state (E1) in other (E2):? = (E1 - E2)/h, where h - the Planck a stationary value. It is established{installed} later, that Bohr postulates - inquest of a quantum mechanics.

MILLETGRASS (Borah) William (1865-1940), the chairman of a commission of a senate the USA on foreign affairs in 1924-33; one of main adherents of "isolationism" in foreign policy the USA. Supported establishment of diplomatic relations with the USSR.

BORANES, the same, that boranes.

BORATES of metals, salt boric acids. An example - a bore. Borates apply to water demineralizing, in structure of soap powders, in a glass industry.

BORATES NATURAL, a class of minerals, natural salts of boric acids. The basis{fundamentals} of structures of borates natural - flat triangular radicals - [BO3] 3-and tetrahedrons - [BO4] 5-. It is known ok. 60 minerals: a bore, boracite, a colemanite, uleksit, ljudvigit, etc. The Main{Basic} deposits - salt (a rainfall of lakes), less often skarnovye. Major deposits - an eskar. Inder (Kazakhstan), an eskar. Serls and Bohr (USA), and also to Peru, Chile, China.
