The role of Greek culture representation in socio-economic development of the southern regions of Russia

This article researches how the Greek lingvoculture represented in onomasticon of the South of Russia. The South Russian anthroponyms, toponyms and pragmatonyms are considered in this article and how they verbalize the most important values and ideological views. It is proved in the article that the key concepts of the Greek lingvoculture such as: “Peace”, “Faith”, “Love”, “Heroism”, “Knowledge”, “Alphabet”, “Power”, “Charismatic person” and “Craft” are highly concentrated in the onomastic lexis of the researched region. The mentioned above concepts due to their specific pragmatic orientation are represented at different extend.peer-reviewe

Nuclear structure corrections in the energy spectra of electronic and muonic deuterium

The one-loop nuclear structure corrections of order (Z alpha)^5 to the Lamb shift and hyperfine splitting of the deuterium are calculated. The contribution of the deuteron structure effects to the isotope shift (ep)-(ed), (mu p)-(mu d) in the interval (1S - 2S) is obtained on the basis of modern experimental data on the deuteron electromagnetic form factors. The comparison with the similar contributions to the Lamb shift for electronic and muonic hydrogen shows, that the relative contribution due to the nucleus structure increases when passing from the hydrogen to the deuterium.Comment: Talk presented at the Conference "Physics of Fundamental Interactions" of the Nuclear Physics Section of the Physics Department of RAS, ITEP, Moscow, 2-6 December, 2002; 8 pages, REVTE

Hyperfine Structure of S-States in Muonic Helium Ion

Corrections of orders alpha^5 and alpha^6 are calculated in the hyperfine splittings of 1S and 2S - energy levels in the ion of muonic helium. The electron vacuum polarization effects, the nuclear structure corrections and recoil corrections are taken into account. The obtained numerical values of the hyperfine splittings -1334.56 meV (1S state), -166.62 meV (2S state) can be considered as a reliable estimate for the comparison with the future experimental data. The hyperfine splitting interval Delta_{12}=(8 Delta E^{hfs}(2S)- Delta E^{hfs}(1S)) = 1.64 meV can be used for the check of quantum electrodynamics.Comment: 14 pages, 5 figure

Theory of muonic hydrogen - muonic deuterium isotope shift

We calculate the corrections of orders alpha^3, alpha^4 and alpha^5 to the Lamb shift of the 1S and 2S energy levels of muonic hydrogen (mu p) and muonic deuterium (mu d). The nuclear structure effects are taken into account in terms of the proton r_p and deuteron r_d charge radii for the one-photon interaction and by means of the proton and deuteron electromagnetic form factors in the case of one-loop amplitudes. The obtained numerical value of the isotope shift (mu d) - (mu p) for the splitting (1S-2S) 101003.3495 meV can be considered as a reliable estimation for corresponding experiment with the accuracy 10^{-6}. The fine structure interval E(1S)-8E(2S) in muonic hydrogen and muonic deuterium are calculated.Comment: 22 pages, 7 figure

Muonic hydrogen ground state hyperfine splitting

Corrections of orders alpha^5, alpha^6 are calculated in the hyperfine splitting of the muonic hydrogen ground state. The nuclear structure effects are taken into account in the one- and two-loop Feynman amplitudes by means of the proton electromagnetic form factors. The modification of the hyperfine splitting part of the Breit potential due to the electron vacuum polarization is considered. Total numerical value of the 1S state hyperfine splitting 182.638 meV in the (mu p) can play the role of proper estimation for the corresponding experiment with the accuracy 30 ppm.Comment: 18 pages, Talk presented at the 11th Lomonosov Conference on Elementary Particle Physics, Moscow State University, August 200

Proton Zemach radius from measurements of the hyperfine splitting of hydrogen and muonic hydrogen

While measurements of the hyperfine structure of hydrogen-like atoms are traditionally regarded as test of bound-state QED, we assume that theoretical QED predictions are accurate and discuss the information about the electromagnetic structure of protons that could be extracted from the experimental values of the ground state hyperfine splitting in hydrogen and muonic hydrogen. Using recent theoretical results on the proton polarizability effects and the experimental hydrogen hyperfine splitting we obtain for the Zemach radius of the proton the value 1.040(16) fm. We compare it to the various theoretical estimates the uncertainty of which is shown to be larger that 0.016 fm. This point of view gives quite convincing arguments in support of projects to measure the hyperfine splitting of muonic hydrogen.Comment: Submitted to Phys. Rev.

In this work, the samples of the gas composition of fermented products were investigated. The analysis of the sample gas composition was performed on a small-size quadrupole mass spectrometer MS7-200 with direct sample introduction at atmospheric pressure, developed at IAP RAS

Analysis of time in range depending on the method of assessing the glucose level

Introduction. In recent years, there has been an increase in the prevalence and incidence diabetes type 1. The high-quality glycemic control is critical in reducing the risk of developing and progression of vascular complications and adverse outcomes of diabetes. Self-monitoring blood glucose (SMBG) and professional continuous glucose monitoring (PCGM) provide the data set which must be interpreted using multiple indicators of glycemic control. A number of researchers have demonstrated the relationship between the time in range (TIR) and the risk of developing both micro- and macrovascular complications of diabetes. Considering the insufficient amount of data on TIR differences depending on the glucose level assessment method and the significant potential of using this indicator for the stratification of the risk of both micro- and macrovascular complications of diabetes, the study of TIR differences based on the data of PCGM and SMBG is relevant at present.Aims. To estimate the time range according to professional continuous glucose monitoring and self-monitoring of blood glucose levels in the patients with diabetes type 1 among the adult population to improve the control of the disease course.Materials and methods. An interventional open-label multicenter study in the patients with diabetes type 1 was conducted. The patients with diabetes type 1 aged 18 and older, with the disease duration of more than 1 year receiving the therapy with analog insulin was enrolled into the study. The calculation of the indicators of the time spent in the ranges of glycemia was carried out on the basis of the data of PCGM and SMBG.Results and discussion. We examined 218 patients who met the inclusion criteria and did not have exclusion criteria. The presented differences in the indicators of time in ranges indicate the comparability of the SMBG and PCGM methods.Conclusions. When assessing the indicators of time in the ranges of glycemia obtained on the basis of the data of PCGM and SMBG, clear correlations and linear dependence were demonstrated, which indicates the comparability of these parameters regardless of the measurement method
