Investigation of the Effect of the Arbitration Court of Health Insurance and Health Care of St. Petersburg on the Organization of Medical Care in the City
No full textThe purpose of the research is to explore the main
factors which determine the effectiveness of the activities of the
Arbitration Court of Health Insurance and Health Care of St.
Petersburg.
The object of research – the results of the work of the
Arbitration Court of Health Insurance and Health Care.
To achieve the goal, the following research methods have been
used: questionnaires, the method of sociological research and
descriptive method.
By analysing scientific literature and the results of research
conducted in foreign countries, the authors have identified the
five indicators characterizing socio-economic importance of the
Arbitration Court for public health in Saint Petersburg
Funded Pillars in the Pension Systems of Estonia, Latvia and Lithuania
No full textThis paper focuses on the comparison of legal
frameworks and performance of funded pillars in the pension
systems of the Baltic States. The author places main emphasis on
mandatory second pillar schemes, but also touches upon
voluntary third pillar characteristics. Comparative analysis of
contemporary pension legislation includes eligibility rights,
contribution rates, allowable investment strategies, etc.
Performance of pension funds is assessed using the comparative
analysis of vast amount of statistical data
Calculation of Complex Eigenvalues for Axisymmetric Problems in Eddy Current Testing
No full textIn the present paper we consider the solution of the eigenvalue problem for the following three cases: (1) a coil with alternating current above a conducting cylinder of finite size, (2) a coil above a conducting plate with bottom cylindrical hole and (3) a coil above a conducting half-space with a flaw in the form of a cylinder of finite size. Computational algorithm is described and results of numerical computations of eigenvalues are presented for all three cases mentioned above
Biosurfactants Enhanced Remediation of Historically Contaminated, Multiple Fraction Soil
No full textThe scope of this research is to perform bioremediation of historically polluted, multiple fraction soil with glycolipid-based anionic biosurfactants. The aim is to optimize the conditions for ex situ soil washing by involving statistical data analysis tools for experimental data. The quadratic interaction model shows that the most influential process parameter at a 95.0 % confidence level was observed for the biosurfactant concentration variable. The results of the study proved the potential for applications of “plate” tests for the formulation of new soil washing products and for the selection of proper biosurfactants for the problem under study
New High-Gain Step-Up DC/DC Converter with High-Frequency Isolation
No full textThis paper presents a new step-up DC/DC converter
topology. The converter is intended for applications that require
a high gain of the input voltage and galvanic isolation, i.e. power
conditioning systems for alternative energy sources such as fuel
cells. The operation principle of the converter is explained by
help of a steady state analysis. Simulation results are presented
and analyzed. Finally, the experimental results are provided and
a modification possibility of the proposed converter is discussed

Sustainable Thermal Insulation Biocomposites from Locally Available Hemp and Lime
No full textThe key focus of the presented research is on sustainable thermal insulation biocomposites which can be made from locally available hemp and lime. The main gains of the use of such material are given, with emphasis on CO2 reduction. In the first stage samples of an artificial hydraulic lime using three different limes and three hydraulic additives are created and tested, the one with the highest compressive strength (DL60 lime with 40% metakaolin addition) are chosen for further research. In the second stage three different density mixes with the chosen binder are
created, optimal hemp/binder ratio is determined, as well as compressive strength and thermal conductivity. Results indicate that created mixtures have good potential as self - bearing thermal insulation material used in low - rise buildings
On-demand Data Integration for Decision-making Applications
No full textDecision-making efficiency depends upon timely availability of appropriate data. On-demand data integration from web based data sources provides an attractive solution to data gathering. The two major challenges associate with on-demand data integration are selection of appropriate data services and efficient implementation of the data integration process. In this paper, it is proposed to use service’s business value as a service selection criterion and to elaborate a lightweight method for XML based definition of the integration processes. The business value driven approach implies that services are selected according to their impact on quality of decisions made rather than solely according to their QoS characteristics. The data integration process definition methods partitions the data integration process into atomic data integration tasks, thus allowing for high level of data retrieval parallelization, accommodating data interdependencies and enabling error recoverability without delaying the whole data integration process. The data integration methods are evaluated using a case study, which investigates on-line decision making at a taxi company
Preparation and Structural Properties of Free Films from Rapeseed Oil-Based Rigid Polyurethane-Montmorillonite Nanocomposites
No full textThe preparation of free standing films of biobased rigid polyurethanes (PU) from rapeseed oil (RO) and diethanolamine (DEA) polyol and its modification with organomontmorillonite (OMMT) nanoparticles are described. Heat enthalpy of the interaction during in situ mixing of RO/DEA polyol and OMMT is measured in isothermal profile. The Fourier transform infrared spectral analysis (FTIR-ATR) is used to determine the urethane group concentration and hydrogen bonds formation in PU and PU/OMMT nanocomposites. X-ray diffraction shows the formation of intercalated and exfoliated structures of OMMT. The glass-transition temperature is used to demonstrate the formation for the intercalated and exfoliated nanocomposites of an interphase with a possible compact structure and the altered polymer chain mobility. The prepared PU/OMMT nanocomposites are also characterized by the enhanced thermal degradation characteristics upon heating in air atmosphere
