On the possibilities of large-scale radio and fiber optics detectors in cosmic rays
Different variants of radio and fiber optics detectors for registration of super high energy cascades in the atmosphere and in dense media are discussed. Particularly the possibilities for investigation of quasi horizontal cosmic ray showers (CRS) and simulated muons from these CRS with the help of radio detectors and fiber optics detectors located on the ice surface are considered
Magnetic field induced transition in a wide parabolic well superimposed with superlattice
We study a parabolic quantum wells (PQW) with
square superlattice. The magnetotransport in PQW with
intentionally disordered short-period superlattice reveals a surprising
transition from electrons distribution over whole parabolic well to
independent-layer states with unequal density. The transition occurs in the
perpendicular magnetic field at Landau filling factor and is
signaled by the appearance of the strong and developing fractional quantum Hall
(FQH) states and by the enhanced slope of the Hall resistance. We attribute the
transition to the possible electron localization in the x-y plane inside the
lateral wells, and formation of the FQH states in the central well of the
superlattice, driven by electron-electron interaction.Comment: 5 pages, 4 figure
Reproductive toxicity of carbon nanostructured material - a promising carrier of drugs in laboratory mice
At the same time, the purpose of this study was to evaluate the reaction of the reproductive system on the carbon nanostructured material "Taunit (multi-walled carbon nanotubes), that was injected to laboratory miceyesBelgorod State Universit
Scientific rationale for inclusion of a new nature complex Belyj Kolodez (Russia, Belgorod Region) into the emerald network
The article shows that there are resources for extending the national list of potential Areas of Special Conservation Interest (ASCI's) of the Emerald network in densely populated and old-developed regions. The representativeness of the Belyj Kolodez nature complex (Russia, Belgorod region) is substantiated. Based on the survey of the territory, the types of priority habitats were identified according to the EUNIR classificatio
