The article reveals main reasons for developing
tendencies to the using of new types of energy, which
are limited supply of traditional fuels and
environmental problems associated with its
processing. It is shown that new forms of energy
plays an important role in the energy supply of many
countries of the world, and in the future they can
become the main sources of energy to meet the
growing needs of the global economy. We reveal
main reasons of the increasing interest in renewable
energy, and we show the obvious prospects of their
use, due to two factors. First, according to experts,
the global reserves of traditional fuels are limited, and
secondly, this was evidenced by the investments of
leading countries in this promising industry. The
article lists reasons for the need for the use of
renewable energy sources in Russia. Increased
consumption of natural resources has become a real
threat to the security of the life of human society. The
basis of solving modern social and environmental
problems is a transition to a regulated process of safe
use of natural energy potential to meet the vital needs
of people not only in the coming decades, but in the
long run. It is concluded, that the determining
condition for the development of the human
civilization at present and in the future would be the
level of natural resources which ensures the needs of
the population without making harm to the
environment
The analysis of the existing mechanical ways to determine the traction resistance of agricultural machines and development of new constructions of plants for engineering assessment of soil-cultivating working bodies has been presented in the article
The example of the delivery process of asphalt mix-tures for the roads repairing is shown in this article using the special computer program
In the article we have reflected a relationship between
the parameters of the research activities of scientific
and pedagogical collectives and the characteristics of
the educational environment in higher education. It is
known that the research activities of scientific and
pedagogical workers and teams - an integral part
functioning of the higher education institution (and
improving its efficiency is one of the most important
problems). The authors proved that parameters
reflecting research activity of scientific and
pedagogical higher education of institution employees
characterize the aspects of the educational
environment as its latitude, intensity, social activity,
coherence, mobility, stability, reliability and
efficiency. It is caused by the fact that the research
activities of scientific and pedagogical workers - a
multifaceted social and cultural phenomenon. The idea
of the diagnosis of the educational environment of a higher educational institution and its structural units,
based on an assessment of scientometric indicators
(criteria for research productivity), can be completely
suitable for international and Russian requirements:
the well-known Shanghai procedure shifts the
emphasis on the evaluation of various aspects of the
research activities in higher education; serious
attention to assessing the research activity focuses and
Russian technique diagnostic efficiency of higher
education institutions. This is logical and soundly: if
the educational environment of a higher educational
institution is not a center of science, then it cannot
have effectively and competitive graduates, because
Research and pedagogical staff - the governing factor
in the educational process. Based on previously
developed models of research activities in scientific
and pedagogical collectives, as well as on generally
accepted models of educational environments, the
authors have proposed a method for the diagnosis of
the educational environment, based on an assessment
of scientometric indicators - parameters reflecting the
impact of the research activities of scientific and
pedagogical workers. Obtained results may be the
theoretical basis for further scientific understanding of
the problem of increasing the productivity of research
activities in higher education, as well as problems -
increasing the competitiveness of educational
environments. The practical significance of the results
of this study - the possibility of their use in the system
of socio-pedagogical monitoring - monitoring of
productivity the research activities and effectiveness of
educational environments. Methods of investigation:
modeling, methods of the theory of sets and relations,
methods of probability theory and mathematical
statistics, methods of the theory of limits, methods of
linear algebra and analytic geometry, multi-parameter
analysis of the systems and methods of quality control
(latent variables theory). Methodological bases of
research: a systematic, metasystem, qualimetric,
sociological and probabilistic and statistical
approaches
In this article we have given the description of grain deformation under grinding according to its visco-elastic peculiarities. The relations of time, deformation rate, dynamic coefficient and geometric parameters of the working disks having original design have been shown
Some possible ways to control the quality of plasma coating are presented. An advanced method of plas-ma coating perfection is observed. It is characterized by combination of plasma spraying with simultaneous electromechanical treating of coating. The analysis of combined process factors is given. Besides, there are computer modeling results of process factors effects on coating quality parameters
The efficiency of an ultra-low-volume spraying (ULV) of field crops was substantiated; we have also presented high performance complex machines
Existing welding materials for the welding of austenitic steel with chrome and nickel were examined in this article. We also gave the economic justification of the usage of cored wires when welding the austenitic steel with chrome and nickel in comparison with coated electrodes
An integral part of technological process for the cultivation of agricultural crop is the transportation. It requires significant energy and labor costs. The statistics show that the proportion of expenses for transportation of goods in agriculture reaches 25-40% of the total costs for the production made, when the proportion of farm tractor transportations reaches 60% of the total. Thus there are considerable losses of production, reaching in separate cases up to 50%. They are especially high in the harvesting and post-harvest cycles of crop production which is connected with crop damage during transportation. The quality of fruits and vegetables during the harvest depends on the technology of its collection and transportation. Due to the rapid deterioration of most agricultural products, agricultural producers have the task in careful transportation of the fruit. A huge role in the preservation of the product is its harvesting and packing into containers. In Russia we use wooden boxes, and foreign farmers use containers, whereby they have higher productivity and preservation of fruits. The type of vehicle, the time of a day and the air temperature also have a large impact on crop damage. In Soviet times, various technologies have been developed for harvesting and transportation of the harvest to consumers using various types of forklifts, harvesters and vehicles. In our time, it requires the development of new technologies for harvesting and transportation of agricultural products to achieve a higher level of automation and high profitability of agricultural production
In the article, we give examples of practical realization of the implementation of industrial environmental control for service centers. In order to conduct environmental activities at production environmental control there was developed appropriate documentation, with instructions of the list and timing of the events. Due to the organization of production environmental control at the enterprise of the service center there was a timely opportunity to implement environmental activities, and solve problems in the field of ecology detectable in the control period. To solve problems identified in the implementation of industrial environmental control, the car service enterprise took measures to ensure efficient wastewater treatment, equipped closed places and recycling. The article provides general insights about the necessity and appropriateness of the organization of industrial environmental control. Principles of organization and implementation of industrial environmental monitoring outlined in this article can be applied by enterprises of various economic activities
