THEORETICAL GROUNDS TO FORM PROFESSIONAL COMPETENCE OF FUTURE SPECIALISTS IN ECONOMICS AT UNIVERSITY

abstract 1161602024 issue 116 pp. 316 – 334 29.02.2016 ru 1046
Among other reasons restraining the renewal of education, we can mention its evident irreciprocal and disharmonious character, when instead of gaining the complete social and cultural experience, students in fact get only a part of it – its knowledge component. Nowadays such an approach seems to be insufficient. Our society needs graduates who are further capable of making successful careers and taking various socially meaningful activities. We need citizens who are ready and able to cope with the challenges that they come across in their lives and professional spheres. This sort of ability owes much not only to the bulk of knowledge and skills one can obtain, but to those extra qualities and traits to define which we use the terms of “competence” and “competency”. In some respect, these terms are more appropriate to comprehend the modern goals of education. With reference to various approaches to defining the category of “professional competence” and to the description of its structure and contents, as well as on the grounds of the previously depicted peculiarities of the specialist’s activities, we have formed the concept of “professional competency of a specialist in economics”. Under this term we understand a complex integral entity comprising: cognitive and activity constituents (implying knowledge, abilities and skills developed well enough to perform professional functions in accordance with the norms and regulations of economic affairs), moral and ethical constituents, motivational constituent, rich cultural background, civil maturity and allegiance, tolerance, skills of professional communication, competitive ability, and – due to the dynamic character of economic activities – demand for and ability of continuous education

THEORETICAL INVESTIGATION OF THE INNOVATIVE BRUSH-GRATER DEVICE FOR EXTRACTING FOREST SEEDS FROM PERICARP

abstract 1081504087 issue 108 pp. 1183 – 1197 30.04.2015 ru 1080
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

THEORETICAL INVESTIGATIONS OF STRAW PARTICLES MOTION WHEN LEVELING HAY ROLLS

abstract 1121508079 issue 112 pp. 1099 – 1109 30.10.2015 ru 897
One can see some density irregularity within the roll in the baler with a chamber of constant volume. We have found out that the maximum density of hay roll width (the baler width) is observed in the middle part. This is due to the shape of the hay roll entering the baler. To even the hay rolls they have mounted some rotating disks having some inclined spring pins above the baler. To improve the roller distribution the disks above the baler have been pushed forward forming a tapering gap. The evening discs rotating above the moving roll will cause some relative motion of hay particles. The interaction of the evening disks with the hay roll in the vertical plane will be determined by the elasticity of the hay roll and the weight of the frame with the disks. We have studied the trajectories of hay particles motion with the help of MathCad program. We have had the following initial parameters: the degree of compaction (decrease of the roll height when evening), the friction coefficient, the angle rate of the evening disks, the number of pins and the speed of the hay roll. As a result we have got the trajectories of the hay particles motion when the evening disks functioning. The analysis of the trajectories has allowed to establish some basic parameters of the evening device such as the distance of 0.15…0.2 m between the pins; the degree of compression while evening 20...25 %, the angle rate of the evening discs 23...30 rad / s and the diameter of the evening disc 0.74 m. The application of the evening device in the form of the disks with pins provides a uniform distribution of hay particles edgewise of the baler ensuring preliminary hay roll seal press before passing to the baler pressure chamber that contributes to getting the rolls with larger mass and a uniform distribution of hay density inside the roll

THEORETICAL JUSTIFICATION OF CONSTRUCTIVE AND REGIME PARAMETERS OF THE ARABLE AND MILLING UNIT

abstract 1521908023 issue 152 pp. 275 – 287 31.10.2019 ru 352
Pre-planting preparation of soil in the Central part of the North Caucasus according to the traditional technology of cultivation of crops involves the use of single-operation soil processing machines and aggregates. As a result, they have to make multiple passes, resulting in increased energy consumption, soil compaction, and the emergence and development of erosion processes. In addition, the agricultural machinery used is characterized by the low operability and reliability of the working elements and their joint assemblies, which leads to a decrease in productivity, so that the agricultural requirements for the process of pre-sowing soil preparation are often not met. In order to solve the above-mentioned problems, an arable milling unit for pre-sowing soil preparation is proposed. Its structural and technological scheme is justified. The distinctive features of the proposed design are the possibility of the main soil treatment with simultaneous grinding of large soil clumps, lumps, plant residues and levelling of the soil surface; possibility of changing the installation angle of the rotary grinder and depth of soil treatment depending on the type of treated soil; high quality of soil preparation for sowing; provision of energy consumption reduction due to combination of technological operations in preparation of soils for sowing; lack of expensive assemblies and parts; the need for less energy for aggregation when preparing soils for sowing. As a result of the theoretical studies carried out, rational values of the main parameters of the proposed arable milling unit have been established, which have a decisive influence on the process of its operation: speed of movement 1.5... 2.0 m/s; Angle of attack of working element 20... 300; Angular rotation speed of the working tool 20... 25 s-1

THEORETICAL JUSTIFICATION OF CONSTRUCTIVE AND REGIME PARAMETERS OF THE UNIT FOR PROCESSING OF ROW-SPACINGS AND TRUNK STRIPS OF FRUIT PLANTINGS

abstract 1511907020 issue 151 pp. 232 – 243 30.09.2019 ru 382
Reserves of expansion of the areas under fruit plantings in the central part of the North Caucasus are limited, one of solutions of this problem is involvement in an agricultural turn and, in particular, under fruit plantings a little or the slope lands, absolutely inconvenient for one-year cultures, having optimum climatic conditions. Currently, scientifically based technologies of cultivation of gardens on slopes are developed for foothill and mountainous areas of the North Caucasus in relation to zones. Large corporations, as well as medium and small business are engaged in production of fruits in the North Caucasian Federal District. One of problems which vendors of fruits face it is the shortage of the equipment on care of trunk strips and row-spacings of fruit plantings. Mechanized technologies of flat gardening are a little effective in specific conditions of mountain and foothill agriculture where the main limiting factor is the soil fertility. At the same time, the question of the accelerated creation of a humic layer in the trunk strips, improvements of the water and food modes of fruit plantings on slope lands is particularly acute. The carried-out analysis of a system of maintenance of the soil in gardens showed that the most rational is the cespitose and humous system providing bevelling of vegetation with its leaving on the surface of the soil in the form of mulch. However, lots the mower-grinders produced by the industry have rather low rotating speed of a rotational operating part (540 … 840 min-1); they do not provide high-quality crushing of grass vegetation, are incapable to transport crushed grassy masses in trunk strips of fruit-trees. In this regard, we offer a construction of a unit for processing of row-spacings and the trunk strips of fruit plantings. As a result of the conducted theoretical researches, we have set rational values of key parameters of the offered unit
