“…The professional competence of the engineer is not only defined with the basic knowledge and skills, but also by the value orientations, motives of the activities, understanding of their position in the word and the world around them, the style of relationships with people, the ability to understand and affect the spiritual world of people, general culture, and the ability to develop their creative potential (Hovardas and Korfiatis, 2011). The unity of the general cultural, social-moral development of a person actualizes the engineers' development of environmental culture (Bennett and Bennett, 2004;Gendler et al, 2015).…”

The environment is the base for the existence and development of humanity in general. As shown by the history of the development of civilization, it is exactly the relations with nature and the integration of the human being with the environment that formed many cultural views in the social environment. However, the constant development of the technologies declares the lack of the need in the integration of the environment. There is no system of environmental education in the training of specialists in the general context, not only in the form of adaptation to a particular profession. The novelty of the study is defined by the fact that the authors of the paper show the opportunity of forming the environmental culture of future engineers in the general structure of their professional training. They showed the aspects of the structural development of engineers as the main sources of technogenic impact on the environment. They also formed the basic parameters of the environmental activities’ allocation among the engineers and presented the opportunities of increasing the environmental culture based on the introduction of particular pedagogical methods during their training. The practical significance of the study is defined by the fact that the environmental culture in the nearest future will define the opportunities of its own development and the transformation of the entire society in general.

Regional feed supplies in Yakutia include hay stocks, succulent feeds, as well as own production and import of concentrated feeds to the republic. Main winter feeds include hay, silage, and haylage; in summer grass of natural pastures is available. Annual provision of livestock with nutrients reaches 60-65% of normal, which is a limiting factor for the development of the genetic potential of local cattle breeds in Yakutia. Understanding of general patterns in digestive processes and physiological and biochemical mechanisms of assimilation of nutrients was based on the results of the studies of domestic ruminant animals (cattle, sheep). Issues of increasing feed security remain urgent for agro-industrial production. The authors describe in detail a method of obtaining a protein-vitamin concentrate having pharmacological properties. Most of these processes involve gas components, liquid or solid substances. Complex hydrodynamic, thermal, and mass exchange processes occur simultaneously in fermenters. A method for expanding the production of feed protein using a combination of hydrodynamic and mass transfer characteristics and parameters with simultaneous optimization of the fermenter design and its operation modes is proposed, taking into account minimum energy consumption for oxygen dissolution and biomass production, based on technical capacity. Various types of devices are currently available; basically, they provide oxygen supply, as it is an integral part of device design, for the cultivation of microorganisms based on microbial synthesis. It should be emphasized that a fermenter is the main device of any microbiological production and largely determines its economic effectiveness. The obtained results will allow considerable acceleration of finalizing works for the development and improvement of perspective fermenter designs.

The results of the analysis of statistical data on accidents at Russian mines caused by explosions in the workings space have shown that explosions of methane-dust-air mixtures at underground coal mines are the most severe accidents in terms of consequences. A detailed analysis of literature sources showed that in the total number of explosions prevails total share of hybrid mixtures, i.e. with the simultaneous participation of gas (methane) and coal dust, as well as explosions with the possible or partial involvement of coal dust. The main causes contributing to the occurrence and development of dust-air mixture explosions, including irregular monitoring of by mine engineers and technicians of the schedule of dust explosion protective measures; unreliable assessment of the dust situation, etc., are given. The main problem in this case was the difficulty of determining the location and volume of dust deposition zones in not extinguished and difficult to access for instrumental control workings. Determination of the class-shape of coal dust particles is a necessary condition for constructing a model of the dust situation reflecting the aerosol distribution in the workings space. The morphological composition of coal mine dust fractions with dispersion less than 0.1 has been studied. Particle studies conducted using an LEICA DM 4000 optical microscope and IMAGE SCOPE M software made it possible to establish the different class-shapes of dust particles found in operating mines. It was found that the coal dust particles presented in the samples correspond to the parallelepiped shape to the greatest extent. The mathematical model based on the specialized ANSYS FLUENT complex, in which this class-form is incorporated, is used for predicting the distribution of explosive and combustible coal dust in the workings space. The use of the obtained model in production conditions will allow to determine the possible places of dust deposition and to develop measures to prevent the transition of coal dust from the aerogel state to the aerosol state and thereby prevent the formation of an explosive dust-air mixture.
