The paper presents an analysis of oil wells construction at oil fields of Eastern Siberia. The petrophysical formation cross-section affecting the quality of oil wells construction is characterized. In addition, drilling and casing experience under those mining and geological conditions demonstrates that, as of today, there are no readily available technologies that would afford safe and efficient construction of oil wells in that region. The analysis of the oil wells construction gives grounds to demonstrate indispensability of a comprehensive approach to solving the problems of construction and operation of oil wells at oil fields of the Talakangroup of deposits.

The construction geological condition is complex in the transition section from the inclined shaft to the main hole. There are two kinds of construction schemes. After the comparison of the advantages and disadvantages of the two different construction schemes, it has selected the construction scheme of the rectangular pilot tunnel vertical to the main hole. This paper solve the construction problem of the transition section from the inclined shaft to the main hole of large cross section tunnel of passenger dedicated line under complicated geological conditions. According to the previous research results, the method can be used to large-cross section tunnel. The scaffold design and auxiliary construction measures is detailed. Compared with the expected duration, it completed the transition construction ahead of time with the speed superior to the ones of other similar works, and forming a safe and efficient construction situation.

The article describes content of original and relevant but virtually forgotten thesis of V.V. Voronov on lighting of production site interiors by means of overhead natural (using three types of skylights) and artificial illumination, in order to elaborate scientific methodology for architectural design of more qualitative luminous environment on the basis of comprehensive approach and enhanced criteria framework of its evaluation using light engineering parameters. The thesis is unique in terms of the scope and quality of field and laboratory observations which are reflected not only in the text but also in the graphical attachments, namely photos, figures, schemes, drawings, charts, nomograms, and diagrams accompanied by specific measured or calculated parameters. The first part of the thesis contains theoretical basics and results of field observations conducted by different methods. This second part is the exposition of chapter 3 of the V.V. Voronov’s candidate thesis (1985). It describes the methodology for and the results of the experiments by means of planar and volumetric light simulation using the architectural lighting simulating assembly (chamber) which were conducted in MARKHI in 1970–1985.

Recent empirical work on globalization and inflation analyzes multicountry data sets in panel and/or cross-section frameworks and reaches inconclusive results. This paper highlights their shortcomings and reexamines the issue utilizing heterogeneous panel cointegration techniques that allow for cross-section heterogeneity and dependence. It finds that in a sample of developing countries globalization of both trade and finance, on the average, exerts a significant and positive effect on inflation, whereas in a sample of developed countries there is, on the average, no significant impact of openness. Neither type of openness disciplines inflationary policy. Despite this, there are large variations in the effect across countries, due possibly to differences in the quality of political institutions, central bank independence, the exchange-rate regimes, financial development, and/or legal traditions.

The article offers a method to solve Buckley-Leverett’s problem, taking into account the nonlinear dependence of the filtration rate of viscoplastic oil on the pressure gradient. This method is based on the transformation of the fractional flow function by introducing in the theory of water drive the equations reflecting the rheological features of the oil flow. The resulting model allows us to quantify the influence of rheological factors on the completeness of the water-oil displacement and to calculate the performance, taking into account the component composition of the hydrocarbon phases. Taking the Samara Region oil fields as an example, the article shows that the quality of design is unsatisfactory when the bundled software being used does not take into account specific non-Newtonian properties of the high-viscosity oil.

Background and objectives: Total parenteral nutrition (TPN) has great clinical importance in malnutrition treatment and prevention in patients with digestive problems. Although good practices for handling TPN are well established, contamination of these products still occurs, and this product remains listed as a higher risk drug by the Institute for Safe Medication Practices. The present study aimed to obtain an overview of the documentary data of the parenteral nutrition samples sent to the National Institute for Quality Control in Health (INCQS) of Fundação Oswaldo Cruz. Methods: This is a qualitative descriptive and quantitative study carried out based on a cross-section of TPN samples analyzed from 2000 to 2016. Results: A total of TPN 134 samples were sent during the study period. 11.20% of the samples were sent in 2001, 0.80% in 2005, 8.20% in 2006, 16.40% in 2007, 63.40% in 2013. Six samples (4.5%) were canceled and 113 submitted to sterility testing, resulting in 13.3% unsatisfactory samples. Conclusion: During the study period, four suspected events of enterobacterial contamination in TPNs administered to patients were reported, three of which have not yet been described in the scientific literature. For the safety of patients using TPN to be guaranteed, it is suggested that the norms that regulate TPN therapy be reviewed and updated, and programs to monitor the quality of these preparations should be established.

Assessing the quality of environmental objects, identifying the causes of pollution and predicting the future state is an urgent and important task, since it is the quality of natural objects that largely determines the state of human health. This paper presents results of the statistical analysis of the data of water quality monitoring in the rivers within oil fields of the Khanty-Mansi Autonomous Okrug Yugra during 20182019. The correlation analysis (according to Pearson) was carried out to identify the relationships between the samples of hydrochemical parameters and the number of microorganisms of various ecological-trophic groups. As a result of the correlation analysis of the relationship between the indicators of the chemical composition of water, a direct and inverse correlation was obtained for the following indicators: total iron, anionic surfactants, nickel, phenols, copper, sulfates, ammonium ions, lead, phosphates, manganese. The maximum value of the correlation coefficient is observed for Ni and Cr concentrations. For total iron and manganese, a significant positive correlation is also revealed. The distribution of chemical compounds in the rivers doesnt have a pronounced correlation dependence, which is probably due to the heterogeneity of the composition of the waters, as well as to the increasing impact on the environment of the oil and gas complex.
