FISCAL EFFICIENCY OF ADMINISTRATION OF DUTIES UKRAINE
Published 2018-09-01“…The article states that import duty is a common tool for regulation of foreign economic activity, along with this it increases the price of goods and reduces its competitiveness.The forecasting of budget revenues from the duty for the near future has been performed. The coefficient of collection of import and export duties has been calculated and its dynamics has been highlighted.It has been found that customs payments are characterized by a regularity of revenues, as the population often needs the consumption of goods and services.The monitoring of the taxation of foreign economic activity in Ukraine made it possible to find out that the fiscal function of custom duty appears to be insignificant in relation to other tax payments, but the nature of customs administration is manifested in its regulatory influence. …”

Field investigation of efficient thermal conductivity of snow cover on Spitsbergen
Published 2015-03-01“…The data obtained were processed by means of the Fourier technique that allowed deriving relationship between thermal conductivity and snow temperature in regimes of cooling and warming of the snow cover surface. It was found that coefficient of efficient thermal conductivity increases with rising of the snow temperature in the regime of the snow surface cooling, and it does decrease under regime of warming. …”

The effect of the magnetic field on the shielding efficiency in a rubidium atomic clock
Published 2025-06-01“…The significant influence of these fields in their interrelation on the shielding properties of the magnetic shield of the RAC has been found. The obtained results allowed us to determine the longitudinal RAC-shielding coefficient at the effective values of the operational and additional magnetic fields and, as a consequence, to compensate for the effect of geomagnetic field variations on the frequency of the onboard RAC.…”
