06.00.00 Agricultural sciences
DescriptionAs the result of 4-year researches there were studied the main economic characteristics of the apple-tree varieties Retina, Renora, Revena Reanda, Remo and Piccolo. The varieties that were positive selected in fruit crop productivity, quality and keeping capacity were recommended for wide productive experiments. There was shown the possibility of use of studied alien varieties as pollinators

THE ACCUMULATION OF COPPER AND ZINC COMPOUNDS IN BLACK LEACHED SOIL UNDER TECHNOGENIC POLLUTION
DescriptionThe influence of exogenous form of heavy metals intake on their transformation in the soil is determined during the model experiment. Distinctions in quantity of extracted mobile compounds of heavy metals in the soil depending on a form of addition various connections of Cu and Zn are established. The smallest mobility of Cu and Zn at addition of heavy metal oxides is observed. It is established that Cu accumulates mainly in the fraction connected with organic matter, Zn accumulates in residual fraction and in the fraction connected with ferric oxide and manganese oxide by consecutive fractionation technique

GROWTH AND PRODUCTIVITY OF POPULUS TREMULA L. IN THE KOSTROMA REGION
06.00.00 Agricultural sciences
DescriptionA comparison of quantitative and qualitative performance of the selected clones of breeding of A.S. Yablokov and S.N. Bagaev has been made. At the same forest conditions, the clones are much higher than regular at reserves, the absolute completeness, the average heights and diameters of trees. Gigantic forms of P. tremula L. are resistant to infectious diseases, and at the fifth grade are characterized by good sanitary condition. We have also shown the economic feasibility of using of fast-growing clones in the genetic reserve for the organization of giant aspen of P. tremula L. plantation

01.00.00 Physical-mathematical sciences
DescriptionIn this article, a model of preons electric currents caused by the motion of preons in the electron shells and nuclear shells is proposed. It is assumed that preons currents may contribute to the conductivity of the material than, for example, due to different sign of the charge carriers to be determined by the Hall effect. It is shown that in metals and semiconductors, nuclear reactions can occur with rapid interruption of the current. An explanation of the known results on the transmutation of elements obtained in the explosion current-carrying conductors

SU(3) GLUEBALL GLUON CONDENSATE
01.00.00 Physical-mathematical sciences
DescriptionIn a scalar approximation the distribution of a gluon condensate in a glueball is calculated. In this approximation the SU(3) gauge fields are separated on two parts: (1) is the subgroup, (2) is the coset . Using an approximate nonperturbative quantization technique two scalar fields are applied for the description of the SU(2) and coset degrees of freedom. In this approach 2-point Green's functions are a bilinear combination of scalar fields and 4-point Green's functions are the product of 2-points Green's functions
