HISTORY OF DEVELOPMENT AND SPECIES DIVERSITY OF GARDENING SYSTEM IN VORONEZH
DescriptionThe article deals with the historical data about the stages of development of greening of Voronezh, as well as it gives an analysis of the modern species of deciduous trees in the greenery planting of the city

Description
In the article, we made an estimation of pine cultures’ (Pinus silvestris L.) sanitary condition in the Savalsky Forestry area of the Voronezh region. The obtained results show their considerable weakness, passing to the drying phase because of pine fungus

Description
Protective forest plantations, shelter belts and plantings along the highways of Central - Black Earth region and southern Russia are badly damaged, and in some areas destroyed. Therefore, they can not perform their functions and require major reconstruction or restoration. The most resistant and applicable trees and shrubs to create protective forest plantings are: maple, ash, elm species and three-thorned acacia, honey-locust, white and yellow acacia, and other legumes breeds with high drought tolerance, disease resistance, technogenic pollution and pest damage. For the creation and restoration of protective forest plantations we require seeds of these species containing pericarp. In Voronezh State Forestry Academy we have carried out a scientific research for creation of a machine for extracting seeds from the legumes. Analysis of the results of scientific research of prototyping machines showed that they were made without considered technological and mechanical properties of the legumes theoretical researches workflow machines for extracting seeds from the legumes and scientific basis of design parameters and operating modes. In this article we have a presentation of the experimental sample of the machine for extracting seeds from the legumes and theoretical investigation of the workflow in the batch hopper. According to the results of the study, we have obtained a mathematical expression, which allows you to define the parameters and modes of operation of a brush-grater device

Description
The article shows the possible ways to control the quality of plasma coatings, such as modulation of the electrical parameters of indirect and remote arc plas-ma torch, vibration, thermal and electro-coating pro-cess, etc. Theoretically based on mathematical model-ing and experimental results of the effect of modula-tion of electrical parameters of the plasma deposition and hardening coatings on their quality are listed. We also developed new high-saving technologies and equipment for applying and hardening coatings on in-ner and outer compact surface on flat, cylindrical and shaped the surface of parts of friction pairs
