This paper explores the impact of the COVID-19 pandemic on crowdfunding by analyzing a 2-year sample of 7,024 rewards-based crowdfunding campaigns on the two major Russian platforms. The study employs a digital methods approach to demand and supply and multiple regression analysis. The findings show that COVID-19 and the associated lockdown had no immediate and straightforward effect on the crowdfunding sector, neither on backers nor on campaigns' initiators. Thus, the crowdfunding sector unlike some other investment classes remains resilient to the global pandemic. Beyond that, empirical analysis revealed the undescribed phenomenon of sponsors' readiness to fi- nance projects being highly seasonal and depending on the month in which the project starts. The nearer to year end, the more backers are willing to put into crowdfunding projects. [ABSTRACT FROM AUTHOR]

The article is devoted to the study of aviation insurance system in Russia. The novelty is the presentation of aviation insurance as a system of elements. Within the framework of the study, the ranking of insurance companies by indicators of financial stability was carried out on the basis of the methodology proposed by Sberbank. The most stable company is National Insurance Group. An important result is the comparative analysis of aviation industry and aviation insurance industry in the period before and after the COVID-19 pandemic. As a part of the study, the dynamics of passenger traffic was analyzed, and the features of the formation of insurance rates before and after the announcement of the COVID-19 pandemic were revealed. The authors offer recommendations for insurance companies in order to help them overcome the crisis as soon as possible. [ABSTRACT FROM AUTHOR]

Underground water is one of the main sources of radon for households. This article focuses on the estimation and removal of radon from underground water using the technology and inorganic sorbents developed by EKSORB Ltd., Russia for liquid radioactive waste treatment in the nuclear power industry. The article presents the results of tests of a system for the removal of radon and radon daughters from water patented by EKSORB. This is achieved by filtering water through RATZIR sorbent, followed by periodic load regeneration. Over a period of three years, the plant is successful in removing radon from the water that had an initial radon content of approximately 1500 Bq/L to less than 60 Bq/L, without releasing radon to indoor/outdoor air.

This paper examines various aspects of designing a part-of-speech (POS) tagset for annotating a textual corpus in the Tuvan language of Siberia (Turkic family). The issues raised are relevant by extension to designing tagsets in other languages. Preliminary issues discussed are Tuvan linguistic structure, the rationale for preferring a POS tagset at initial stages of corpus design, the metalanguage and orthography of the tagset, and the potential usefulness of existing tagsets for designing a new tagset. The paper then presents the specific linguistic attributes that are encoded in the Tuvan tagset, using the three-level model of Major Class > Subclass > Features. Difficulties involved in deciding whether a specific type of word is a major class or a subclass are illustrated with Tuvan language data. The actual structure of the individual tags to be used in the tagset is also discussed, examining several existing models that differ in terms of transparency and level of linguistic detail. Sample Tuvan words that have been tagged using the system laid out in the paper are provided to illustrate how this tagset design facilitates searching for decomposable morphosyntactic elements relevant to the grammatical structure of Tuvan (as well as that of other Turkic languages.).

The article presents study which examines the structure of sea tides in the diurnal range based on the material of sea level observations in the Barents Sea and Kara Sea, Russia. It says that harmonic analysis was made on the basis of least squares (LSM) in the diurnal range of potential tides that are resolved in the nodal periodic cycle. It cites that 179 waves were computed in the diurnal tide category from a total of 197 terms of the second and third degree in the potential's decomposition. The results show that the tides of the third degree have amplitudes at all points larger than what follows from the theory of the potential decomposition. It adds that the deviation of the third degree tides from the rule is related to the low reliability of estimates at small values of amplitudes.
