The article discusses the pedagogical conditions for the development of friendly relations among older preschool children through collective work. Experimental work on the formation of friendly relations among older preschool children through collective labor is described.

The article deals with the issue of creating an automated meteorological station based on the Raspberry Pi microcomputer using a sensor associated with the Arduino microcontroller. At the same time, access to the stored information is carried out through a mobile interface based on the nginx web server.

This article discusses the seasonal fluctuation of the pipe of the underwater passage of the main gas pipeline on the section of the Khatasskaya channel of the Lena River, during the re-formation of the main channel.Special attention is paid to the section of the coastal slope where seasonal exogenous processes occur in the form of frost heaving and thawing of the soil, which directly affect the stress-strain state of the main gas pipeline. The choice of the left bank is directly related to the fact that the layer of seasonal freezing, starting from the near-rim plot, interlocks with the zone of permafrost soils. To determine the seasonal fluctuations of the two lines of the main gas pipeline, the method of surveying the planned-high-altitude position of the pipeline was used. It is noted, that oscillations can reach up to two meters vertically, seasonally moving horizontally to the channel of the Khatasskaya channel.

The results of long-term monitoring of microbiological activity of disturbed lands after an oil spill that occurred on the territory of the Southwestern part of Yakutia are presented. It has been established that after the introduction of biological preparations based on the native hydrocarbon-oxidizing microflora in soils, both with fresh and old oil pollution, the microbiological activity of soils intensifies. The activation period of hydrocarbon-oxidizing activity of soil microorganisms in the cryolithozone was about 7 years for fresh oil pollution and 3 years for soils with old oil pollution. Therefore, the method of activation of biological destruction of oil pollution with the use of native hydrocarbon-oxidizing microorganisms is not relevant for permafrost soils with long-term oil pollution. It is necessary to develop new ways to restore disturbed lands with long-term oil pollution.

A model of the geoelectric structure of the frozen soil thickness is proposed, including a layer of their transitional permafrost. Monitoring of changes in this layer is proposed to be carried out by observing seasonal changes in the parameters of geoelectric sections, obtained as a result of radioimpedance or RMT sounding. Viewing changes in geoelectric sections over time, allows you to determine the parameters of the selected layer of transitional frost as the main ones when monitoring the state of frozen soils. An indicator of the iciness of soils is proposed. Electromagnetic emission of frozen soils occurs during intensive thawing or freezing of water in the active layer. The amplitude of the field by electromagnetic emission of frozen soils is twice as large when they melt as when they freeze. The intensity and duration of the melting and freezing of soils can be estimated by the amplitude of the field created by electromagnetic emission.
