Abstract Research was carried out on the volume of gas turbine commissioning in the range of unit capacities of 30–125 MW at TPPs of the Russian Federation operating as part of a CCPP in the period from 2015 to the first quarter of 2021. The purpose of the research was to determine the average specific capital investment in construction and the average specific fuel consumption for the supply of electricity and heat for the CCPP introduced over the years in the united energy systems of the Russian Federation. Gas turbines are classified by electrical capacity into three groups: from 100 to 125 MW, from 60 to 99 MW and from 30 to 59 MW. An assessment of the quantitative distribution of gas turbines over the interconnected energy systems of the Russian Federation has been carried out. The results of the comparison of the quantitative commissioning of gas turbines are shown in the period from 2010 to the economic crisis of 2014 and in the period from 2015 to the present. A preliminary estimate of the increase in average specific capital investments in the construction of CCPP, which included gas turbines of the same electric power, was made for these periods.

The article suggests a technique for relation global kinematic reference system and local static realization of global reference system by regional continuously operated reference stations (CORS) network. On the example of regional CORS network located in the Novosibirsk Region (CORS NSO) the relation parameters of the global reference system WGS-84 and its local static realization by CORS NSO network at the epoch of fixing stations coordinates in catalog are calculated. With the realization of this technique, the main parameters to be determined are the speed of displacement one system center relativly to another and the speeds of rotation the coordinate axes of one system relatively to another, since the time evolution of most stations in the Russian Federation is not currently provided. The article shows the scale factor for relation determination of coordinate systems is not always necessary to consider. The technique described in the article also allows detecting the errors in determining the coordinates of CORS network in global coordinate system and compensate for them. A systematic error of determining and fixing the CORS NSO coordinates in global coordinate system was detected. It is noted that the main part of the error falls on the altitude component and reaches 12 cm. The proposed technique creates conditions for practical use of the advanced method Precise Point Positioning (PPP) in some regions of the Russian Federation. Also the technique will ensure consistent PPP method results with the results of the most commonly used in the Russian Federation other post-processing methods of high-precision positioning.

According to the Constitution of the Russian Federation, every citizen has the right to freedom of movement on its territory, but due to the fact that minors cannot be held accountable for their actions, there is a need to control their movement by legal representatives. The practical determination of the age of independent travel of minors and the issues of drawing up documents by parents authorizing them to do so are the subjects of disputes that are subject to judicial resolution. The article provides an analysis of the relevant practice, accompanied by the author's comments.

The determination of operation area from en-route alternates for long-range airline aircraft is an important aspect of ensuring safety of the upcoming flight. In the domestic and foreign methodological literature on flight planning, including the guidance material for flight planning systems, there is no single reasonable algorithm for constructing operation areas of long-range aircraft, including the use of the EDTO-ETOPS rules. The lack of methodological materials leads to the «free» values determination of areas of operation by airlines for their long-range aircraft while building routes, in particular, when determining the areas of operation on the route, the decrease in the aircraft weight during fuel combustion is ignored. A big question is also the «initial» mass calculations to determine the value of operation areas. The article identifies shortcomings of existing algorithm for identifying the areas of operation based on the fundamental methods for determining area of operation. Microsoft Excel 2019 has been used to perform a polynomial approximation of the table-specific function of the dependence of operation radius on the mass of a long-range aircraft. Based on the certain equations, more advanced algorithm to determine areas of operation has been developed. The new algorithm pays special attention to the selection of the original value of operation area. The calculations in this article are made for the Boeing 777 as the main type of long-range aircraft operated by airlines in the Russian Federation. The developed algorithm increases the flexibility of the route by increasing the radius of operation areas from en-route alternates and can be used in flight planning systems of airlines.

Financing capital-intensive projects in the green economy is possible through green bonds. The assessment of the economic efficiency of the green bond market, the determination of its role in ensuring the energy and economic security of the regions and the development of directions and instruments for improving the efficiency and significance of the market for the Russian Federation are the aim of the study. The methodology involved the determination of the autocorrelation presence in the calendar series of bond yields using the Broysch-Godfrey LM test, the application of applied statistics methods to verify the existence of calendar effects on the stock exchange and analyze market reviews. Data on the green bond market were compared with data on other bonds. Market performance calculations were based on the S&P Green Bond Index and S&P 500 Bond Index. Features and benefits of green bonds as an instrument to ensure regional security were identified. The lack of market efficiency for green and other bonds, even in a weak form, was shown. The necessary institutional changes to improve the efficiency of the green bond market and develop it in the Russian Federation have been proposed. The findings are of theoretical importance, complementing the work on testing the hypothesis of an effective market, and of practical importance in the form of recommendations for on market improving.

Turbine Performance

Earlier analytical and graphical treatments of gas turbine performance, assuming the working fluid to be a perfect gas, are developed to allow for ‘non-perfect’ gas effects and pressure losses. The pressure ratios for maximum power and maximum thermal efficiency are determined analytically; the graphical presentations of performance based on the earlier approach are also modified. It is shown that the optimum conditions previously determined from the ‘air standard’ analyses may be changed quite substantially by the inclusion of the ‘real’ effects.

There were 105 patients with shoulder replacement under our supervision (terms of supervision were up to 10 years). There were 43 men and 62 women. Age of patients was from 29 to 80 years. Two ways of optimization of shoulder replacement are offered: “Method of preoperative determination of the sizes of a head of shoulder joint endoprosthesis” (Patent of the Russian Federation N 2469670 d.d. 12.20.2012) and “Method for intraoperative navigation of a shoulder stem of joint” (Patent of the Russian Federation N 2467725 d.d. 11.27.2012). We reached the improvement of quality of the operation due to the fact of an installation of the implants which are as much as possible close to the anatomy of a normal shoulder joint by size and position.

The article presents the survey data of 1830 average samples of feed, feed raw materials and food products received through the Test Center of the FSBSI «FCTRBS-RRVI»", provided by livestock and feed enterprises, agricultural companies, food manufacturers and 152 samples of feed provided by specialists of veterinary services , livestock enterprises, owners of peasant farms to determine the death of animals and birds, for the content of mycotoxin deoxynivalenol (DON) in the period from 2018 to 2020. Determination of the DON content in the samples was carried out according to a certified procedure based on the method of thin layer chromatography. In the course of summarizing the results, it was found that samples of feed, feed raw materials and food products received through the Test Center of the of the FSBSI «FCTRBS-RRVI» from different regions of the Russian Federation in terms of DON content corresponded to the normative indicators specified in the current regulatory and technical documentation. When determining the cause of death of animals and birds, 152 samples were examined, received from farms of different regions of the Republics of Tatarstan, Bashkortostan, Mordovia, Kostroma and Ryazan regions. It was found that 1.97% of samples were contaminated with DON at concentrations from 0.2 to 0.5 mg/kg of feed, in the rest, the content of mycotoxin was below the sensitivity of the method (< 0.2 mg/kg), which does not exceed the limit permissible concentration. It was recommended to exclude feed contaminated with mycotoxin from the diet of animals, since at the established concentrations, DON is not the main etiological factor in the death of animals, but due to the presence of carcinogenic, mutagenic, teratogenic, embryotoxic and immunosuppressive properties, together with other factors, it is contributing.
