Smoking and its association with socio-economic and cardiometabolic risk factors in the population 25–45 years of Novosibirsk. the problem of female smoking (2013–2014)

The article presents the results of population-based study of a representative sample of the population of one of the districts of Novosibirsk, conducted in 2013–2014. A total of 749 people of both sexes (43 % men) aged 25–45 years were examined. The response rate was 38 %. The program included a survey questionnaire on smoking and socio-economic factors (education, marital status, employment). Measurement of blood pressure, anthropometric parameters, serum cotinine, total cholesterol and its fractions, blood glucose were conducted. The high prevalence of smoking among men (46 %) and women (24 %) revealed. Associations of smoking with cardiometabolic risk factors such as hypertension, hyperglycemia and hypo-HDL-C were received. On the subsample (273 people) using the verification of the questionnaire on smoking by serum cotinine 4–6 % false answers were found. Marked increasing in female smoking and decreasing in male smoking in the past 20 years in Novosibirsk were revealed

Crystal structure of a new HfO(OH)2 oxyhydroxide

The crystal structure of a new hafnium oxyhydroxide obtained by an ion-exchange reaction from a Li2HfO3 precursor has been solved by a direct method and refined using Rietveld full profile fitting based on X-ray powder diffraction data. HfO(ОН)2 crystallizes in a P21/c monoclinic unit cell (a = 5.5578(5) Å, b = 9.0701(10) Å, c = 5.7174(5) Å, β = 119.746(5)°); its structure can be described as a framework formed by edge-sharing HfO6 octahedra connected to each other via vertices. In addition, an analysis of the atomic pair distribution function obtained using synchrotron radiation was used to confirm the model and to describe fine-structure features

Photo - and radioluminescence of lithium hafnate Li2Li_{2}HfO3O_{3}

Photoluminescence, excitation and pulse cathode luminescence spectra, and decay kinetics of lithium hafnate Li 2HfO 3 were investigated at temperatures 300 and 7.5 K. Time-resolved luminescence spectra were excited with synchrotron radiation in UV-VUV range. Strong emission with the peak position at 4.42 eV and with the decay time in μs range was revealed at T = 7.5 K. The emission was attributed to radiative decay of self-trapped excitons (STE). The features observed in the excitation spectra at 6.6 eV were likely to take place because of the exciton formation, with inter-band transitions dominating at 6.7 eV. Crystal structure defects underpin the luminescence spectra formation at room temperature in the frame of vacancy model. © 2012 Elsevier B.V. All rights reserved
