DEVELOPMENT OF FOREST RAW MATERIAL AND TECHNOLOGICAL PREPARATION OF FOREST HARVESTING MANUFACTURE
DescriptionThe article presents the analysis of the transformations of preparatory works in Russian system of forest exploitation and suggests a number of solutions for their modernization
-
Description
In this work, the example of skidding vehicle passes distribution along a skidding trail is considered. The distribution is determined when vehicle capacity is being decreased in skidding process because of rut depth increasing on the soils with low bearing capacity

EVALUATION OF PARK PLANTING IN THE SYSTEM OF GARDENING OF PETROZAVODSK
DescriptionThe 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

10.00.00 Philological sciences
DescriptionThe purpose of this article is an attempt to show the value of translated Russian novels of the XVIII c. in formation of premise to the birth of a new literary genre – “slavic” fantasy. V.A.Levshin’s, M.D. Chulkov’s and M.I. Popov's contribution to development of a domestic fantasy can't be underestimated: by copying style of the traditional chivalric novel, they decorated the text with elements of the oral national tradition

Description
The article proposes the updated model of the influence of logs length onto a size of wooden chips produced with the use of a disk chipper. This article focuses on the fact that the length of any of the logs in the process of chipping is reduced. For this reason at the final stage of chipping, any of the logs with a standard initial length of 1.2 m inevitably transform into short logs, for which the conditions of chipping are significantly different from the chipping conditions at the start of chipping. The task of accounting for these changes is reduced to finding a solution of the transcendental equation. The results of numerical simulation indicate a progressing decreasing trend in the bevel angle and increasing in the length of the particles of wood chips with decreasing of logs length. Adequacy of the modeling results confirmed by laboratory tests and production experiment. Measuring linear and angular dimensions of chip real particles showed that the particles of such length may be equal to 7 cm, which is 3.5 times larger than the standard length of 2 cm. The angle of the bevel of the cutting plane of the particle may be 14º, which is approximately three times less of standard value equal 39º- 43º. We also discuss the comparison with the approximate solution, which was published in 2012 year. The article can be useful for specialists of wood-preparatory cycle in the paper industry
