EXPERIMENTAL RESEARCH EFFORTS TO UPROOTING TREES AND BUSHES PLANTED
DescriptionThe article presents the methodology and the results of experimental studies to determine actual values of effort arising from uprooting trees and shrubs plan-tations in the Republic of Mari El. On the basis of experiments and regression analysis we have established the coefficients of the approximation-defining relation between the force and the diameter of the stem of tearing depending on the type of crops

FORMATION OF MICROBE-PLANT CONSORTIUMS OF THE RHIZOSPHERE IN ONTOGENESIS OF GRAIN CROPS
06.00.00 Agricultural sciences
DescriptionThe microbiological composition of the rhizosphere of the soft wheat (Triticum aestivum L.), the two-row barley (Hordeum distichon L.) and the sowing oats (Avena sativa) was studied. It is shown, that the total number of the rhizosphere microorganisms changes during the plant growth and development. The specificity of the microbial composition of the three studied cereal crops has been observed

PHILOSOPHICAL REASONING OF THE CONCEPT OF THE GAME AND ITS USAGE IN NON-PLAYING CONTEXT
DescriptionIt is interesting for interdisciplinary understanding of game phenomena, how the concept of the game discourse can operate in different non-playing contexts. Researching of game concept allows tracing the figurative conceptualization knowledge of this universal phenomenon. The author uses a lot of examples to prove that game phenomenon represents itself in a language and has been reflected in the mind of people. It is shown, that lingvo-culturological concept of the game has more productive metaphorical rethinking. We single out the most important characteristics of game, explain some imaginations about gaming, explicate dominant sense of game freedom, its choice, imitation, dynamic and emotional stress, agonistic, risk, unpredictability and others attribute the symptoms. Represented contexts of usage also illustrate communicative and social components of gaming behavior. Dominant meanings, key ideas, that unite viewed image, actualize basic principles that are typical for the game phenomenon in common, and the specific characteristics of different types of games (sport, children, gambling, theater, computer, etc.)

RISK MANAGEMENT IN WOODWORKING
DescriptionThe article deals with urgent questions concerning activities of woodworking industries, which face tough economic situation. Nevertheless, these enterprises reveal a definite growth of output in some kinds of products, such as fuel pellets, window units, special timber assortments, etc. The problems about possible risks connected with equipment handling were identified, which has physical and intellectual wear, as most of it has been operating since 1980. On the basis of accomplished investigations of normative and technical sources the documents were specified, which establish safety regulations for operating equipment and requirements for risk assessment techniques. The necessity of their improvement is also determined. Taking into consideration peculiarities of management of woodworking production process, the analysis was carried out in order to estimate the factors, which influence the quality of mechanical treatment by the method of 5M. Following the observations and processing of statistical data it was established that equipment and personnel show the greatest impact on the quality of half-finished and final products. Risks evaluation method for woodworking industries is suggested with due account for equipment safety parameters, which includes determination of consequences, risk probability, risk level on scale factored “high”, “medium” and “low”. Much attention is paid to the items composed: rank matrix of two-factor model, with calculations of numerical values of risks, as product probability of occurrence and severity of consequences, and risk log. Three zones were appointed with the following risk levels: the first zone with weighting factor not less than 6, the second zone: 8-16, the third: 20-25. In course of investigation, it was detected that the highest risk factor, connected with equipment operation, is probability of mechanical injuries of hands and most possible – getting cuts. The flow chart of risks management during the woodworking production process is offered in accordance with all Union State Standard regulations R ISO 9001-2015 and GOST R ISO/MAC 31010-2011. The developed algorithm provides accomplishing performance of work on risks management in more available and short form with presentation of processing operations, actual doers, kinds of required normative documents and papers worked out within the enterprise
