STRUCTURE AND SPECTRAL-LUMINESCENT PROPERTIES OF THE SILICATES OF RARE EARTHS WITH APATITE STRUCTURE
01.00.00 Physical-mathematical sciences
DescriptionCaGd4 x y zYbxEryCez(SiO4)3Osingle crystals were grown by the Czochralski method, the concentration dependence of the luminescence decay kinetics of the levels 4S3 / 2, 4I11 / 2 and 4I13 / 2 ions Er3+and X-ray analysis conducted for these crystals. By the results of stereo atomic analysis, it is shown that there is possible to estimate the lifetimes of levels, i.e. predict the probability of multipole interactions

CASCADE PHOTON EMISSION IN LUMINOPHORES AND STEREOATOMIC ANALYSIS
01.00.00 Physical-mathematical sciences
DescriptionThe relation between degree of sphericity of the Voronoi-Dirichlet’s polyhedron G3 and the ability to demonstrate the first stage of the cascade luminescence of Pr3+ for several crystalline fluorides and oxygen-containing compounds was revealed. It was found that LaZr3F15 and BaSiF6, with energy level 1S0 located below the bottom of 5d-band, which demonstrate cascade luminescence have the smallest value of G3 among investigated compounds

HUMUS STATE OF SOILS IN CROP ROTATIONS OF DIFFERENT STRUCTURE ON COMMON BLACK SOILS
06.00.00 Agricultural sciences
DescriptionBased on many years balance studies, the possibility of humus stock maintenance in common black soils for crop rotations of different structures is given in the article. Fertilizer omitted crop rotations with bare fallow and without it, with perennial legumes and small variations in parts of other crop are considered

STATEMENTS FOR THE ROLE OF ROOT AND AFTERMATH RESIDUES IN AGROCENOSES
06.00.00 Agricultural sciences
DescriptionThe role of root and aftermath residues of basic field farm crops for retention and increase in organic matter content of the soil with fertilizing and fertilizer omitted is substantiated in the article. It is ascertained that the quantity of aftermath residues coming into the soil is 2,6-3,5 times less than that of natural vegetation while dry matter is removed with the main production and by-products 2,0-2,2 times more than is remained in the soil
