Berries instead of bears: new insight into gastronomic attractiveness of Russian Siberia
Ermolaev Vladimir A.,Ruban Dmitry A.,Yashalova Natalia N. 한국식품연구원 2021 Journal of Ethnic Foods Vol.8 No.-
Active use of berries in regional cuisines underlines gastronomic specifics of Russia. The present study focuses on three regions of Russian Siberia and establishes that edible berries are numerous there and determine specifics of the regional cuisine rooted into the cultural traditions. These cultural and gastronomic traditions developed during four centuries by Russian settlers in Siberia who adapted to severe natural conditions, explored new food resources, and interacted with the local peoples. If so, berries and berry products can be regarded as a kind of ethnic food. Modern berries-based tourism (bacatourism) initiatives and, particularly, berry picking and tasting at you-pick farms and raspberry festival are registered on the study territory. Sellers tend to position berry products as typically Siberian, which permits their use as regional, quasi-ethnic souvenirs. Berries determine significant gastronomic attractiveness of Southern Siberia, and further exploitation of this potential can contribute to sustainable development of this vast territory and maintaining its cultural identity within the broad and diverse Russian space.
Levitation characteristics of HTS tape stacks
Pokrovskiy, S.V.,Ermolaev, Y.S.,Rudnev, I.A. The Korea Institute of Applied Superconductivity a 2015 한국초전도저온공학회논문지 Vol.17 No.1
Due to the considerable development of the technology of second generation high-temperature superconductors and a significant improvement in their mechanical and transport properties in the last few years it is possible to use HTS tapes in the magnetic levitation systems. The advantages of tapes on a metal substrate as compared with bulk YBCO material primarily in the strength, and the possibility of optimizing the convenience of manufacturing elements of levitation systems. In the present report presents the results of the magnetic levitation force measurements between the stack of HTS tapes containing $n=2{\div}200$ of tapes $12mm{\times}12mm$ and NdFeB permanent magnet in the FC and ZFC regimes. It was found a non- linear dependence of the levitation force from the height of the array of stack in both modes: linear growth at small thickness gives way to flattening and constant at large number of tapes in the stack. Established that the levitation force of stacks comparable to that of bulk samples. The numerical calculations using finite element method showed that without the screening of the applied field the levitation force of the bulk superconductor and the layered superconductor stack with a critical current of tapes increased by the filling factor is exactly the same, and taking into account the screening force slightly different.
