Deeper insight into the features of a reactor as a source of antineutrinos is required for making further advances in studying the fundamental properties of the neutrino. The relationship between the thermal power of a reactor and the rate of the chain fission reaction in its core is analyzed. 相似文献

Nanostructures formed during the reduction of ionic selenium in the selenite-ascorbate redox system in an aqueous solution of bovine serum albumin (BSA) were studied using static and dynamic light scattering and flow birefringence. It was established that this process results in the formation of stable aggregates of selenium nanoparticles that adsorb BSA molecules. It was found that highly-ordered superhigh-molecular-weight spherical nanostructures with high density and unique morphology are formed. Experiments with a cell culture of promyelocytic leukemia HL-60 showed that BSA adsorbed on selenium nanoparticles can inhibit the growth of tumor cells and deactivate free radicals with an efficiency comparable with that of sodium selenite. 相似文献

Processes of the inelastic magnetic and weak scattering of tritium-beta-source antineutrinos on the bound electrons of a germanium atom are considered. The results obtained by calculating the spectra and cross sections are presented for the energy-transfer range between 10 eV and 18 keV. 相似文献

The nanostructures formed by reduction of Se(IV) in the selenite-ascorbate redox system in an aqueous solution of supermacromolecular polycation, poly[trimethyl(methacryloyloxyethyl)ammonium] methyl sulfate, were studied by static and dynamic optical scattering and flow birefringence. 相似文献

1. | Carbon-chain polymers with -diketone and -keto ester functional groups in the side chains have been synthesized. |
2. | The tautomeric equilibrium of the polymeric -dicarbonyl compounds polymethacryloylacetone and poly(vinyl acetoacetate) and low-molecular models of these polymers has been studied. The effect of the macromolecular nature of the polymeric -diketones on the tautomeric equilibrium is expressed as a significant difference between their thermodynamic equilibrium parameters and those of the low-molecular analog. |

A characteristic equation is derived for an isotropic spherically layered ionosphere with allowance for ground reflections. An analytic model of ionospheric reflection is presented. Simple formulas are provided that relate various characteristic ionosphere heights. It is shown that the electromagnetic field calculated as a mode sum matches the Sommerfeld plane-case field in the near zone and that for ranges greater than 1 mm the incoherent field describes the average field well.St. Petersburg State University.

In [1], it was shown that the standard version of the spatio-temporal ray optics (STRO) can only be used in the case of fairly
weak frequency dispersion of the medium and cannot describe the dispersive refraction effect related to the transverse frequency
modulation and having geometric-optical spatial and temporal scales. In the present paper, we propose a simpler way of deriving
the revised spatio-temporal ray equations which are based on the model of a field with smooth transverse inhomogeneity of
the amplitude in the form of an Airy function.
