DEVELOPMENT AND RESEARCH OF THE EXPERIMENTAL EQUIPMENT FOR COMBINED TILLAGE
DescriptionThe article substantiates the necessity of creation the experimental equipment for examination of the power components in the investigated process; a block diagram of the measuring system was presented. We have also developed a method of selecting a mounting location and connection schemes of the sensors, as well as the approbation of the experimental equipment is made in the implementation of a trial of full factorial experiment

MANAGEMENT PROCEDURE OF LOGGING ROUTES OF OIL AND GAS PIPELINES AT FOREST TERRITORIES
DescriptionProcedure of management by process of routes logging is developed for linear objects (oil and gas pipelines and power lines) by petrol saws, delimbing-bucking machines and timber transport road trains in wood territories. The documents and the performers providing management of operations and the registration of the quality of the works, the resources and the equip-ment, used in the process of logging are defined

SECURITY ASSESSMENT PROBLEMS IN SAWMILL EQUIPMENT
DescriptionThe article deals with normative legal documents, regulating safety indicators of equipment, with particular focus on woodworking machinery, including log-processing equipment. General and specific requirements have been highlighted in terms of their analyses. The necessity of safety requirements’ specification in technical guidelines, with reference to construction of industry-specific trend equipment, according to newly accepted national, interstate and international standards for purposes of conformity assessment. Nonconformities were determined on the terms in Technical Guidelines of the Customs Union 021/2011, fundamental documents for woodworking equipment GOST EH 1070 and GOST ISO 12100. Relevant topic issues are declared in this work. Manufactures consider them when risk valuation is performed in point of existing equipment and that, under development non-standard equipment, connected with diversity of normative documents, absence of information about customers’ experience, accidents while operating comparable machinery, etc. The paper emphasizes complications, which participants of standard programs face, namely, development contractors and users, accredited test laboratories and certification bodies, state oversight authorities, when woodworking machinery conformity assessment is performed. The suite of safety metrics was suggested for valuation of log-processing equipment and two-level log frames, particularly, on the basis of technical guidelines requirements TG CU 021/2011 “On machinery and equipment safety”, and standards GOST EH 1070, GOST 12.2.026.0, GOST R 5454123 and GOST R 51898. The necessity of standard realization was demonstrated in relevance to obsolete methods of control over equipment (geometric and technology accuracy). GOST 10294 was accepted in 1990 and hasn’t been actualized since that time. That is the reason why it seems impossible to estimate equipment condition, as recommended monitoring facilities are missing

Description
The main tendencies of the development of forestry in the Russian Federation under the implementation of the Forest Code of 2006 are discovered, the goals of forming the institutional environment for forests use, conservation, protection and reproduction at the present stage are defined. The activities in the field of conservation, protection and reproduction of forests in the country in the period from 2007 to 2013 are characterized by a decrease in the volume of work and activities. A steady upward trend in the loss of forest resources from forest fires was outlined. The state policy of the Russian Federation in the area of use, conservation, protection and reproduction of forests is aimed at conservation and augmentation of forests, maximum satisfaction of the needs for high quality products and useful properties of forests. The achievements of stated objectives were provided by solving of a number of tasks, including the increase in efficiency of the forest sector management and intensification of the use and reproduction of forests, which have the priority meaning. The authors determined the institutional model of public-private partnership in the forest sector of the Russian economy recognizing the need to develop flexible institutions for interaction between government and business in the use, conservation, protection and reproduction of forests as an integral part of intensive economic model. The article proposes a conceptual scheme of efficiency assessment for investment projects in forest development and target functions for data subjects of investment projects: the federation, the region, the business and local community

USE OF NONTRADITIONAL FERTILIZERS IN CULTIVATION OF PLANTED SCOTCH PINES ON THE RECULTIVATED GROUNDS
06.00.00 Agricultural sciences
DescriptionThe results of use of nontraditional organic fertilizers on the basis of wastewater sludges and sawdust in sand pits earth stabilization are considered. It was ascertained that a dose of introduced fertilizers has higher influence on hydrophysical and agrochemical properties of soils than shelf life of the fertilizers. A tendency of enhancing growth of intended purpose planted pines on the back of improvement of physical and chemical and biological properties of sandy soils, enrichment of species composition with grassland vegetation after nontraditional organic fertilizers treatment is revealed
