Results of a 7-year prospective follow-up in the Interepid study: factors influencing all-cause and cardiovascular mortality in rural residents of Russia and the Kyrgyz Republic

Aim. To assess the 7-year survival rate and the association of risk factors (RFs) with all-cause and cardiovascular mortality among rural residents in Russia and the Kyrgyz Republic, as well as to analyze ethnic characteristics (according to the Interepid study).Material and methods. This study was carried out within the Interepid international project, which included a cross-sectional epidemiological study of the prevalence of major noncommunicable diseases and their risk factors in 2011- 2012, and a prospective stage among rural residents of two countries (Russia, the Kyrgyz Republic). In 2019, the vital status of respondents was reassessed (7 years after the initial examination), and endpoints were collected, including all-cause and cardiovascular deaths.Results. A significant similarity of rural residents of the analyzed regions in relation to the factors associated with mortality was revealed. Smoking in men, obesity in women, and hypertension in both sexes were associated with an increased death risk. Country differences were found only in relation to low physical activity and dietary habits. Ethnic developments in the population of the Kyrgyz Republic also concerned only the contribution of food habits.Conclusion. The results obtained are important for planning, implementing and evaluating the effectiveness of public health promotion programs. It is also necessary to develop differentiated treatment and prevention measures in the Russian population and among the indigenous inhabitants of the Kyrgyz Republic, including taking into account the prevalence of CVD risk factors and their impact on life prognosis

Tensor Ayy and vector Ay analyzing powers in the H(d,d')X and ^{12}C(d,d')X reactons at initial deuteron momenta of 9 GeV/c in the region of baryonic resonances excitation

The angular dependence of the tensor Ayy and vector Ay analyzing powers in the inelastic scattering of deuterons with a momentum of 9.0 GeV/c on hydrogen and carbon have been measured. The range of measurements corresponds to the baryonic resonance excitation with masses 2.2--2.6 GeV/c^2. The Ayy data being in good agreement with the previous results demonstrate an approximate $t$ scaling up to -1.5 (GeV/c)^2. The large values of A_y show a significant role of the spin-dependent part of the elementary amplitude of the NN->NN* reaction. The results of the experiment are compared with model predictions of the plane-wave impulse approximation.Comment: 7 pages, 7 figures. submitted to Yad.Fi

EFFECT OF HEAT TREATMENT ON THE STRUCTURE AND COEFFICIENT OF THERMAL EMF OF FILMS

The electrical properties of thin films (In2O3/SiO2)25 and their stability under high-tem-perature treatment are investigated. The value of the thermal emf coefficient after a series of annealing is stabilized and corresponds to the values for the electrodes of chromel-alumel thermocouples.Работа выполнена при поддержке Министерства науки и высшего образования РФ в рамках государственного задания (проект №FZGM-2020-0007)

THE STRUCTURE AND THE ELECTRICAL PROPERTIES OF HETEROGENEOUS NANOSYSTEMS BASED ON ZnO AND SnO2 OXIDE SEMICONDUCTORS

The effect of heat treatment on the structure and the electrical properties of ZnO/SnO2 multilayer thin-film systems studied. It was found that the films have a layered structure that is stable up to 400°C. After annealing at 400°C and 600°C Mott variable range hopping con-duction mechanism observed.Работа выполнена при поддержке Министерства науки и высшего образования РФ в рамках государственного задания (проект № FZGM-2020-0007)

SOCIO-PSYCHOLOGICAL CHARACTERISTICS OF FIRST-YEAR STUDENTS OF IRKUTSK STATE UNIVERSITY IN ACCORDANCE WITH THE DIFFERENT FIELDS OF STUDY

For the first time the results of social and psychological characteristics of the first-year students were obtained. We performed the estimation of adaptation potential of the first-year students during their studies at the university and depending of the fields of their study (humanitarian, scientific or physico-mathematical). The peculiarities of motivation of the goal achievement need in the first-year students of different fields of study were determined. It was found that most of first-year students (53 %) had an average needs-based motivation and were characterized by low adaptive capacity (66,6 %) and low-neuro mental stability (41,6 %). During the research we used multilevel personality questionnaire "Adaptivity" of A.G. Maklakov and S.V. Chermyanin and test-questionnaire "Goal achievement need" of Y.M. Orlov

OPTICAL PROPERTIES OF (In2O3/SiO2)25 MULTILAYER STRUCTURES

(In2O3/SiO2)25 multilayer structures were obtained by ion-beam sputtering. The structure of (In2O3/SiO2)25 thin films are amorphous. Multilayer structures have high transparency and low electrical resistance, which makes them a promising material for transparent electronics.Работа была выполнена при поддержке государственного задания (№ FZGM-2020-0007)

Measurements of multiplicity fluctuations of identified hadrons in inelastic proton–proton interactions at the CERN Super Proton Synchrotron: NA61/SHINE Collaboration

Measurements of multiplicity fluctuations of identified hadrons produced in inelastic p+p interactions at 31, 40, 80, and 158 GeV/c beam momentum are presented. Three different measures of multiplicity fluctuations are used: the scaled variance ω and strongly intensive measures Σ and Δ. These fluctuation measures involve second and first moments of joint multiplicity distributions. Data analysis is preformed using the Identity method which corrects for incomplete particle identification. Strongly intensive quantities are calculated in order to allow for a direct comparison to corresponding results on nucleus–nucleus collisions. The results for different hadron types are shown as a function of collision energy. A comparison with predictions of string-resonance Monte-Carlo models: EPOS, SMASH and VENUS, is also presented

Measurements of π−\pi ^- production in 7^7Be + 9^9Be collisions at beam momenta from 19A to 150A GeV ⁣/ ⁣cA\,\text{ GeV }\!/\!c in the NA61/SHINE experiment at the CERN SPS

The NA61/SHINE experiment at the CERN Super Proton Synchrotron (SPS) studies the onset of deconfinement in hadron matter by a scan of particle production in collisions of nuclei with various sizes at a set of energies covering the SPS energy range. This paper presents results on inclusive double-differential spectra, transverse momentum and rapidity distributions and mean multiplicities of $\pi ^\pm$, $K^\pm$, p and $\bar{p}$ produced in the 20% most central$^7$Be+$^9$Be collisions at beam momenta of 19A, 30A, 40A, 75A and 150A ${\mathrm{Ge} \mathrm{V}}\!/\!c$. The energy dependence of the $K^\pm$/$\pi ^\pm$ ratios as well as of inverse slope parameters of the $K^\pm$ transverse mass distributions are close to those found in inelastic p+p reactions. The new results are compared to the world data on p+p and Pb+Pb collisions as well as to predictions of the Epos, Urqmd, Ampt, Phsd and Smash models
