PREONS SHELLS AND ATOMIC STRUCTURE
01.00.00 Physical-mathematical sciences
Description
We consider the model of the structure of electrons and quarks, in which these particles are presented consisting of elementary particles preons. From this model, the theory of electron shells, as a continuation of the quark nuclear shells has been proposed

Description
The soil properties out of playing areas of golf courses (so-called roughs) have an influence on the lawn vegetation state. Heavy texture of the soil has the cause of deterioration of the water-air properties of soil which is accompanied by changes in the nature of addition grass lawn from solid to mosaic. Non-aggressive grass of the artificial lawn has one of the reasons for renewal of native flora and the formation of a new type of plant association, closer to the natural vegetation of the Don floodplain

EVALUATION OF PARK PLANTING IN THE SYSTEM OF GARDENING OF PETROZAVODSK
Description
The article presents the results of the state evaluation of trees and shrubs in landscaping plantings of different types situated in four parks in Petrozavodsk. The species and number of plants in good, satisfactory, and unsatisfactory states were determined. The conducted analysis of species distribution and the number of trees and shrubs in each category of state allows working out the activities for planting reconstruction

DYNAMIC COMMUNITIES OF GREENHOUSE BIOCENOSES IN EXPOSITIONS OF TROPICAL AND SUBTROPICAL PLANTS
Description
In this article, the features of dynamic communities’ formation under greenhouse conditions of Tsytsin Main Botanical Garden of the Russian Academy of Sciences are discussed. It has been shown, that complex consortia consisted of different species of higher plants, mosses, fungi and bacteria are formed in the model expositions of tropical and subtropical regions. The diversity of microorganisms, responsible for close interactions with greenhouse orchids and sago palms is reported, and the effects of associative bacteria on growth and development of the host-plant is discussed
