Laser and Plasma Assisted Fabrication of Nanoparticles in Liquids

In this paper capabilities of two plasma assisted methods based on a pulsed laser ablation and electrical discharges in liquid media for fabrication of metallic and composite nanoparticles are discussed

Consumer Loan Demand Modeling

Nowadays in Russia, a strong growth in consumer lending is taking place. During 2017–2019 the part of consumer loans in the total mass of loans was 57%. In Russia, the fight against poverty is one of the national goals, which determines the relevance of research and mathematical modeling of the debt burden on the population. We analyze the debt burden using the database of the Russian Longitudinal Monitoring Survey—Higher School of Economics (RLMS-HSE), which includes the data of 2838 households from 38 constituent entities of the Russian Federation. The households are divided into those who are inclined to take loans and those who do not need credits. Using a modified Ramsey model, it is possible to reproduce the dynamics of consumer loans, cash, consumptions, and the dynamics of deposits over the last decade. The most expected forecasts are presented in accordance with the level of population income loss

Modern Views on Rotavirus Infection in Children: Epidemiological and Clinicopathogenetic Features

Based on the analysis of epidemiological, clinical and laboratory data characterizing the course of rotavirus infection in children of Zaporizhya region, there are provided the modern features of the disease. The authors marked dynamic changes in clinical and laboratory parameters of lactase deficiency, which occur during rotavirus infection in infants. The efficiency of Saccharomyces boulardii in complex treatment of rotavirus infection in children is shown

Scintillation properties of Eu²⁺-doped SrCl₂ and CsSrCl₃ single crystals

Eu²⁺-doped CsSrCl₃ scintillation crystals with activator concentration 0.5, 1 and 5 mol. % and SrCl₂: Eu²⁺ material doped with 1 mol. % of the activator have been grown by Bridg-man-Stockbarger method. The radioluminescence spectra of CsSrCl₃: Eu²⁺ materials include a narrow band with the maximum which position is shifted from 437 to 448 nm with Eu²⁺ concentration increase and the spectrum for SrCl₂:Eu²⁺ contains a band with the maximum at 414 nm. The light yield of CsSrCl₃:Eu²⁺ material achieves maximal value at 5 mol. % of Eu²⁺ and it is equal to 39 % in respect to Nal:TI (ca 16,000 photons per MeV) and energetic resolution R is 11.5 %, whereas for SrCl₂:l mol. % of Eu²⁺ the light yield consists 30 % (ca 12,000 photons per MeV) and R = 9.2 %. The scintillation pulse decay curves for CsSrCl₃:Eu²⁺ is described by two components with the decay constants 420 ns and 2.8 ps and the fraction of the faster component is 0.3
