Innovative technological product: technology for the production of gluten-free cereal bars with the addition of pop sorghum Scope of application of an innovative technological product: manufactures engaged in the production of functional food products with high nutritional value in a relatively small volume are an excellent source of energy, dietary fiber, vitamins, macro- and microelements for the human body, in particular, consumers suffer from gluten intolerance.

Investigation of the effect of laser surface modification on the hardness and wear resistance of a titanium alloy

The effect of laser modification of the surface on the value of the coefficient of elasticity, hardness, coefficient of friction and the amount of wear of the counter body when testing products made of a deformable titanium alloy was investigated. It was found that the indicators of hardness and wear resistance of a titanium alloy depend on the modes of laser modification. These dependencies are extreme in nature, they have maxima and minima. The quantitative values of hardness and wear resistance indicators for the specified material before and after laser treatment of its surface in various modes are given.

Abstract 13048: A Simple Model to Describe the Relationship Between Compression Force and Depth During CPR

Aim: The relationship between force and depth during manual chest compressions depends on the patient and on the dynamics with which the rescuer applies the force. Force-depth models with many fitting parameters have been proposed making physical interpretation complicated. The aim of this work was to design a simpler force-depth model, accommodating anticipated differences in compression and recoil phases. Materials and Methods: Force and acceleration signals were extracted from out-of-hospital-cardiac arrest (OHCA) defibrillator recordings (TVF&R, OR, USA), equipped with CPR technology. Compression depth and velocity signals were computed from acceleration. We analyzed intervals of 20-s within the 1st min of chest compressions. Our model decomposes the applied force as the sum of an elastic and a damped term, considering different damping coefficients for the compression and recoil phases. Coefficient of elasticity was calculated at the instant of maximum compression depth (null velocity) and damping coefficients at the instants of maximum compression and recoil velocities. The estimated depth signal is shown in the figure. The goodness of the model was assessed through the determination coefficient R 2 . Results: We analyzed 1,074 compressions from 30 OHCA recordings. Median (IQR) compression depth was 4.6 (4.0-5.4) cm; compression rate was 107 (102–113) cpm; coefficient of elasticity was 100.67 (78.95–125.01) N/cm; compression damping coefficient was 2.57 (1.84–3.29) N/(cm/s) and recoil damping coefficient was 3.59 (2.58–4.90) N/(cm/s). Median R 2 was 0.993 (0.984–0.996). Conclusions: This model, derived using fewer parameters, could help with the interpretation of the mechanical properties of the chest during CPR. It may also be useful for the assessment of inter-patient differences with age, sex, and body constitution, as well as of the evolution of elasticity and damping of patient’s chest during the course of resuscitation.

A Study on Fish Production of Different Size of Fish Farm Groups in Prayagraj District, Uttar Pradesh

Background: Uttar Pradesh is India’s most populous state having 1662 lakh population as per 2001 census, against 16.2% of India’s population with enough fisheries resources in the form of community ponds, tanks with dominance of rivers and man-made reservoirs. Five blocks (Koraon, Shankargarh, Karchhana, Handia, and Jasara) from Prayagraj were taken for study during the period of 1st December,2020 - 31st May,2021. Aim: To examine the fish production of different size of fish farm groups. Methodology: A study was conducted in the Prayagraj district of Uttar Pradesh. A total of 80 fish farmers were selected randomly from five blocks (Koraon, Shankargarh, Karchhana, Handia, and Jasara) and a pre-structured questionnaire was used to collect the data from the fish farmers. The fish farmers were classified into three categories on the basis of the size of pond area viz. small farmer: up to 0.125 ha., medium farmer: 0.125 ha to 0.250 ha., and large farmer: above 0.250 ha. Result: The Study showed that, various independent variables of production like fingerlings, manures, feeds, and labor were being analysed in accordance with their respective sample of fish ponds and it is concluded that all of the independent variables affected the fish production differently. Using Cobb Douglas production function, 73% variation in gross value return from explanatory variables was observed in first size-group. Effect of Improved variety fingerlings was negative and coefficient of elasticity for human labor was positive but both impacted fish production significantly. A variation of 41.6% in gross value return was observed from second size group. Human labor impacted fish production significantly and its coefficient of elasticity was positive. Further, 45.7% of variation in gross value return was in third size group. Human labor and manure both had a significant effect, and their coefficients of elasticity was positive and negative respectively. Coefficient of multiple determination was 76.6% indicating variation in gross value return from independent variable from all farm’s situations. Pond area and human labor variables had positive coefficient of elasticity but for improved fingerlings it was negative and all effected fish production significantly. Conclusion: It was concluded that there is a need to further engage the fish farmers in the fish production practices and provide them with sufficient inputs of production like fingerlings, manures, feeds, and labor so that the farmers can boost the fish production in the study area.

Assessment of the ecological potential of the region using the method of regression analysis and the coefficient of elasticity for sustainable development

One of the fundamental economic determinants of sustainable development is the optimal use of limited resources and the use of environmentally friendly-nature, energy, and material-saving technologies, including the extraction and processing of raw materials, the creation of environmentally friendly products, minimization, processing and disposal of waste. In this study, in order to clarify the indicator "ecological potential of the region", it is proposed to consider a number of indica-tors that, according to the authors, have a significant impact on this phenomenon. One of the significant indicators for assessing the ecological potential of the territo-ry is the indicator of the area of landfills for the disposal of solid municipal waste (MSW) in a particular region. The authors hypothesize that the change in the vol-umes of landfills for the disposal of solid municipal waste (MSW) in a particular region depends on the type of development of the territory. As the main defining indicators (factors-arguments) of the development of the region were chosen: the number of manufacturing enterprises, population and gross regional product (GRP) per capita. The authors have developed a regression model to determine the degree of influence of a number of socio-economic indicators on the volumes of landfills for the disposal of MSW. Significant parameters were determined for terri-tories with different types of regional development (extensive type of develop-ment. Using the method of regression analysis, it was found by calculation that for regions of all types of development, the decisive factor that affects the volume of landfills for the disposal of MSW is the population of the territory. With the help of the coefficient of elasticity, the closeness of the relationship of the considered fac-tors-arguments was determined.

COMPETITIVENESS OF HOTEL, RESTAURANT AND TOURISM BUSINESS: FACTORS AND TOOLS

The aim is to find ways to ensure sustainable development and increase the hotel, restaurant, and tourism business's competitiveness. The authors used the correlation-regression dependence of the number of tourists going abroad Y on the income of the population X and Fisher's statistical criterion to check the model's adequacy. Authors proposed the system for ensuring sustainable development and competitiveness of the hotel, restaurant and tourism business. The peculiarity of the proposed system is that it covers all aspects of sustainable development, includes multi-level governing bodies, integrable legal forms of organizations and science, making it possible to form interrelated elements of sustainable development and increase the competitiveness of the hotel and hotel industry, tourism in general. In years of political instability, the number of domestic tourists, with a positive upward trend, is falling sharply, despite rising incomes. Fisher's statistical criterion indicates this model's adequacy: an increase in income of the entire population of Ukraine by UAH 10 mln. would lead to the additional appearance of about 8 Ukrainian tourists travelling abroad. The coefficient of elasticity Ex (Y) = 0.9193 shows that an increase in the income of the entire population of Ukraine by 1% would increase the flow of Ukrainian tourists travelling abroad by about 0.9%. The article is devoted to the search for ways to increase the competitiveness of the hotel and restaurant and tourism business. The analysis showed that 2019 was a good year for the entire HRTB. However, the global pandemic COVID-19 in 2020 significantly affected this area: border closures, cancellation of messages between countries, total quarantine, weekend quarantine and other prohibitions. Therefore, the search for a strategy to increase the competitiveness of HRTB facilities in 2020/2021 is the most relevant. The authors proposed a system for ensuring sustainable development and competitiveness of the HRTB. The system covers all aspects of sustainable development.

3D print material study to reproduce the function of pig heart tissue

BACKGROUND: Three-dimensional (3D) printing technology for heart simulation can be represented as complex anatomical structures, and objective information can be provided. OBJECTIVE: We studied 3D print material to find a material with the same elastic coefficient as pig elastic coefficient. METHODS: Pig heart sample, Agilus sample, Tango sample, TPU sample, and silicone sample were studied. The elastic coefficient of each specimen was measured using an elastic coefficient measuring instrument. The analysis was performed using the average value of ten specimens of the same size. We suggested an equation to find the elastic coefficient of material by the thickness using the elastic coefficient of Agilus, Tango, and silicone. RESULTS: The sample with similar elasticity to the pig sample did not show the same coefficient of elasticity at the same sample size. In Tango, the 0.5 mm high elastic force was about 3 times higher than the pig sample 7 mm elastic force. CONCLUSIONS: The study was conducted using 3D print material and silicone which can reproduce the elasticity of pig heart. However, no material is currently available to reproduce pig heart sample of the same size. However, if the heart is developed considering only elasticity, it can be sufficiently reproduced using the research results.

Inflation and innovation value: How inflation affects innovation and the value strategy across firms

This research analyzes the effects of inflation on R&D investments and innovation-driven growth. For this, an innovation-driven growth model was built in which firms invest own resources and resources from financial institutions. Credit costs depend on the interest rate charged by these institutions. In an inflation-targetingregime, the monetary authority adjusts the nominal interest rate in order to converge current inflation to the established target. It adjusts the interest rate of financial institutions, changing the opportunity cost of investments. As a result, rising inflation promotes a reduction in R&D investments demand, reducing the rate of technological progress. In the empirical exercise of the model, the estimated coefficient of elasticity of R&D investments is negatively affected by inflation.

MEASURING THE QUALITY OF THE HUMAN CAPITAL OF THE ENTERPRISE

Stimulating employees of an enterprise with an increase in wages can lead to an increase in labor productivity and to an increase in production costs, which can lead to a decrease in the competitiveness of products. To form an enterprise development strategy, it is necessary to assess the quality of human capital, on which the effectiveness of funds aimed at labor remuneration depends. The paper analyzes the production function of the enterprise, on the basis of which it is proposed to measure the quality of human capital by the coefficient of elasticity of labor. The low value of this indicator gives the basis for the activation of investments in the technological modernization of the enterprise.

Budget sustainability and dynamic of the regional economic development

The paper is devoted to some aspects of regional budget sustainability. The analysis is based on data of revenues of regional budgets of the Far-Eastern federal district. Under the review of approaches to analyzing of budget sustainability we found significant variety of definitions and methods of budget sustainability estimation. The consequence of this diversity is a mismatch of results of scientific researches. We calculated the coefficient of elasticity of tax and non-tax revenues by gross regional product in order to assess the level revenues sensitivity to changes in economic situation. Then we analyzed the dynamics of budget revenues and estimated the scale of fluctuation. The analysis showed that the budget revenues of the territories of the Far-Eastern federal district are mostly characterized by the low level of sensitivity to national trends in the economic development. The degree of their sensitivity to changes in the economic situation in the region is evaluated as high for the Republic of Sakha (Yakutia), the Kamchatka territory and the Sakhalin region. These regions differ significantly in the share of intergovernmental transfers in the income structure, which confirms the absence of direct link between the dependence of the budget on the budget regulation measures and the sensitivity of its revenues to changes in the economic situation. According to the second criterion, the highest risk of reducing sustainability is typical for the Sakhalin region and the Chukotka autonomous region. We share the opinion that complex economic development remains the most important measure for providing of budget sustainability. The results of the study can be used in the educational sphere and become a basis of further investigation devoted to the budget sustainability.
