  • GALOGENEZ (from grech. hals - salt and... A genesis), set of processes of formation of adjournments of readily soluble salts by vaporization of brines in surface basins aridnoj (rainless) zone. Distinguish calcareous (soda), sulphate and hloridnyj galogenez, on genesis of feed waters - continental and marine.
  • HALOGENIDES, chemical combinations of halogens with other elements (fluorides, chlorides, bromides, iodides).
  • HALOGENIDES NATURAL, a class of minerals, the saltlike connections derivative galogenovodorodnyh of acids HF, HCl, HBr and HI. Secrete 2 subclasses: fluorides (over 20 mineral kinds) and chlorides, bromides, iodides (over 30). There are basically in hydrothermal (fluorides) and in salt (chlorides and so forth) deposits, less often in oxidation zone of sulphidic deposits. Raw material chemical and an iron and steel industry.
  • HALOGENATION of organic compounds, introduction in these connections of atoms of halogens. Widely (especially the chlorination and fluorination) is applied to obtaining solvents, khladons, polymers, dyes, etc.
  • HALOGEN LAMP, lamp bulb which structure of gas mixture except for noble gas includes halogens (routinely an iodine or bromine). At equal with a routine lamp bulb of power and life cycle has the smaller dimensions, a major luminance factor and the best stability of a luminous flux.
  • HALOID BREEDS, hemogennye sedimental rocks (a rock salt, gypsum, etc.), generatrix by crystallization from saturated solutions at the bottom of drying up sea basins, lagoons and brine lakes. Most the considerable accumulation of haloid breeds is dated for adjournments of the Perm system.
  • HALOGEN HYDRIDES, chemical combinations of halogens with hydrogen (fluorine hydride, hydrogen chloride, hydrogen bromide, iodic hydrogen).
  • GALOGENOPROIZVODNYE HYDROCARBON (galogensoderzhashchie hydrocarbon), hydrocarbon in which molecules one or several atoms of hydrogen are displaced on atoms of halogen. Raw material in industrial organic synthesis, solvents, khladons.
  • GALLOP (frants. galop), a jerking motion of the horse; one of kinds of a gait. Depending on length of a walk distinguish a gallop short, dace (kenter) and fast (pit).
  • DRIMOPHILUSES (from grech. hals - salt and phileo - I like), the organisms dwelling in conditions of a high salinity - in seas, brine lakes, saline lands, etc. Galofilnye plants (soljanka, the tamarisk, some kinds of a sage-brush, etc.) call as galophytes.
  • GALOSHES (frants. galoches), the rubber shoe mounted atop a boot, a boot, a felt boot, etc. for their protection from damp. The history of galoshes is connected to discovering America when spanish colonialists have seen how Indians alight in juice of a rubber tree of a hevea of a leg and wait, when on them the impermeable film will be derivated. The commercial production of gum, fit for manufacturing galoshes in their modern kind, began in nach. 19 century when galoshes of steel are very popular.
  • CRAVAT (a nem. Halstuch - a scarf), a strip of a tissue, a scarf or a tape enveloping a neck under a collar of the jacket, a blouse, etc. and knotted in front a unit or a bow.
  • FILLET (from a nem. Hohlkehle - a hollow, a groove), 1) rounding internal and exterior angles on machine components, in foundry cores, etc. 2) the Fine-bored rod, protective cracks in joints of connections, napr., component parts of furniture. 3) the Door plane for vystrugivanija on bars of grooves (fillets), figurate profiles (beading planes).
  • BARRELING, superficial cleaning of a small metal goods (from burrs, a blight, a moulding earth, etc.) in rotated (t. n. Tumbling) drums sand, an emery, emery or other abrasives. Apply also vibro-and hydrobarreling.
  • GALOIS the THEORY built by E.Galua the theory of algebraic equations of the maximum degrees with one unknown; establishes conditions of a reducibility of the solution of such equations to the solution of a circuit of other, more simple algebraic equations (it is routine the lowest degrees).
  • GALOIS (Galois) Evarist (1811-32), the French mathematician. Transactionses under the theory of algebraic equations have laid foundation to development of the modern algebra. Its such major concepts are connected to ideas of Galois, as group, a field, etc. The Scientific inheritance of Galois - a small number of rather briefly written activities, because of novelty of ideas not Galoises clearood at life. Are published in 1846 Z.Liuvillem.
  • GALUZO Illarion Grigorjevich (1899-1977), the parasitologist, academician AN of Kazakhstan (1946). Transactionses on a fauna, ecology and measures of extirpation with mites - disease-sampling organisms animal. The state premium of the USSR (1951).
  • GALLOON (from frants. galon), a dense tape or a braid in width of 5-60 mm from a cotton, man-made yarns, silks, often with a reinforced filament. It is used at manufacturing rating badges for a service dress and its furnish.
