UPGRADING OF LOCKING SUPPORTS OF ROD-TYPE DOWNHOLE PUMPS

The article provides analysis of existing structures of lock supports for fixation of plug-in rod-type downhole pumps. Based on the analysis, the connection of the lock support elements and the pump is evaluated. Description is given of the new structure of the lock support equipped with a set of spring-loaded and radially extendable sliders. The latter have conical surfaces interacting in forward and reverse directions with pump armature. The proposed design has high variability, which allows to perform modeling of the product both at the stage of design and at the stage of implementation.

DENDROCHRONOLOGICAL RESEARCHES IN ARTIFICIAL PLANTINGS OF NUR-SULTAN CITY

Dendrochronological analysis was carried out in forest cultures of Pinus sylvestris of different ages growing in the green zone of Nur-Sultan city. It was found that the value of the annual radial growth is subject to a cycle with a period of 10-11 years. This is due to climatic conditions, in particular, with periods of solar insolation, which is confirmed by researches of other authors.

MONITORING RESULTS OF SAZAN (CYPRINUS CARPIO CARPIO LINNAEUS, 1758) POPULATION IN THE EASTERN PART OF THE TAGANROG BAY AND THE DON RIVER DELTA

The materials for 2003-2018 on the biological state of sazan of the eastern part of the Taganrog Bay and the Don River delta were summarized. It has been shown that the catches of sazan in the study area consisted of more than half of the fish of younger age groups, the length of which was less than the commercial measure. The ratio of linear and weight growth of sazan is shifting towards a decrease in the mass of one-dimensional specimen, which is indirect evidence of the deterioration of the natural living conditions of semi-migratory fish. In 2019, the carp parasite fauna was represented by 7 species related to monogenes - 2 species, cestodes - 3 species, nematodes - 1 species, crustaceans - 1. The state of the sazan population needs further research.

ANALYSIS OF MEASURES TO REDUCE ECOLOGICAL AND ECONOMIC DAMAGE FROM AUTOMOBILE TRANSPORT

The article considers common classifications of measures to reduce environmentaleconomic damage from motor vehicles. Classification from the point of view of control impact is proposed, which allows to take into account relations between the state and citizens in the field of reduction of negative impact of motor vehicles on the environment. The analysis of the classification made it possible to identify areas of activity for improving the efficiency of management impacts, taking into account the incentives of citizens to comply with the requirements of the legislation and to create conditions for their exceeding. Increasing the efficiency of resource allocation in the Territory will allow the released funds to be allocated to the development of industry, agriculture, education and science.

SOCIAL DYNAMICS AND SUSTAINABLE DEVELOPMENT

The article examined different views on population with a view to identifying major trends. Social processes that impede the transition to sustainable development within existing governance mechanisms have been identified. It is noted that due to the high social dynamics, the exit from the "modernization trap" is to be sought both by territories with high natural growth of the population, and economically attractive regions with indicators of natural decline of the population. At the same time, social dynamics in different territories in modern conditions involve the risk of its use for the benefit of different social groups and can act as a manageable factor. In order to increase the sustainability of development, in resolving the contradictions of the existing socio-economic system, it is necessary to take into account the peculiarities of agricultural territories and to develop self-sufficient models of their development.

INFLUENCE OF MINERAL SORBENTS ON GROWTH AND DEVELOPMENT OF HORDEUM VULGARE ON SOIL POLLUTED BY BENZ(A)PYRENE

The effect of diatomite and tripoli added into the soil artificially contaminated with benzo[a]pyrene was studied. A decrease in the toxic effect of BaP on barley plants was established when diatomite and tripoli were added as ameliorants to contaminated soil. The improvement of plants grown сharacteristics on soils contaminated with BaP with the addition of diatomite and tripoli was shown up to 2-4 times compare to contaminated samples.
