EXPERIMENTAL RESEARCH EFFORTS TO UPROOTING TREES AND BUSHES PLANTED
DescriptionThe article presents the methodology and the results of experimental studies to determine actual values of effort arising from uprooting trees and shrubs plan-tations in the Republic of Mari El. On the basis of experiments and regression analysis we have established the coefficients of the approximation-defining relation between the force and the diameter of the stem of tearing depending on the type of crops

ASSESSMENT OF ENVIRONMENTAL PERFORMANCE OF LARGE CITIES IN THE CONTEXT OF RAPID URBANIZATION
DescriptionThe article defines the basic characteristics of the environmental performance of urban areas. There was offered the system of environmental performance indicators, covering the basic characteristics of the environmental performance. There was developed the algorithm and calculating methodology of composite index of the environmental performance of major cities in the context of rapid urbanization. There was conducted the approbation of the methodology according to the data of major cities which are the administrative centers of the Russian Federation for 2008, 2009 and 2011. There was carried out the rating of major Russian cities based on the composite index of the environmental performance

STRUCTURE OF FORESTS OF PREDKAMJE OF THE REPUBLIC OF TATARSTAN
DescriptionThe article presets results of the studies that reflect the nature of the distribution of forests of Predkamje of the Republic of Tatarstan on the types of forest grown conditions, the predominant tree species, age, site class, completeness and volume of stem wood. It is shown that there are large reserves of increasing productivity of forest stands by optimizing their density and species composition of forests

Description
In the article we present a method of cutting logs, containing several quality areas. For this method, a mathematical model was developed to determine the volumetric output of lumber, which allows to determine the geometric dimensions of the lumber cut from the different quality areas separated concentric circles, depending on size and quality characteristics of logs
