Abstract
thermokarst refers to cryogenic processes, as a result of which characteristic relief forms are formed, as a result of melting of icy frozen soils or an ice complex. The study of the ...dynamics and distribution of modern thermokarst forms is important from the point of view of using them as one of the main indicators of the degradation of permafrost soils. In recent years, unmanned aerial vehicles, which can create orthorectified images and digital terrain models (DTM) with very high spatial resolution, have been actively used to study thermokarst. This article provides an example of the use of UAVs in the study of the development of thermokarst in s. Uncure. Based on landscape-geomorphological studies and decoding of the created orthophotomap, the areas of thermokarst development were identified. The total land area covered by thermokarst is 0.66 km
2
, which is 19.5% of the territory of the settlement. According to the classification of P.A. Solovyov, two types of thermokarst relief were distinguished here: bylary and alasy. The largest area is covered by bylars, which are the initial stage of the formation of Alas. They are formed as a result of melting of the upper part of revein ice and form a polygonal-lowland microrelief. More than 6,000 elementary polygons with a total area of 0.4 km

were discovered here. The landfill area varies from 6 m2 to 223 m
2
, and the average area is 57 m
2
. They are formed by local areas throughout the area of the village.
The article describes of temperature change consideration during the calibration of air flow sensor for a car engine. The sensor uses a blade made of elastic material with strain gauges applied to ...the front and the back surfaces, the deformation of which is measured and recalculated into a mass flow of air. They suggested the system of equations whose solution makes it possible to determine the mass flow rate and air temperature according to the known signal values at the measuring bridge output and the measuring circuit resistance. The coefficients of equation system are determined during calibration and then are recorded into the memory of the microcontroller sensor.

The branching ratio (ital B) for etar arrowmusup +musup minus has been measured at the SATURNE tagged-eta facility using the reaction ital pdr arrowsup 3He eta as a source of similar to10sup 8 tagged ...eta's per day. A sample of 100 etar arrowmusup +musup minus decays on a background of 8 events yield ital B(etar arrowmusup +musup minus) =5.6sub minus0.7sup +0.6(stat)plus minus0.5(syst)times10sup minus6. This value is 1.3plus minus0.2 times the unitarity (lower) bound of 4.3times10sup minus6, in agreement with most quark and vector meson dominance model predictions.
