Peculiarities and stages of development of sportsmanship of qualified athletes in the system of long- term performances in professional boxing
Authors: Molochko A. S. 
Published: August 2023

The article examines the peculiarities of the formation of the highest sportsmanship of athletes in professional boxing. A comparative analysis of the dynamics of competitive activity of men and women during many years of performances in the professional arena was carried out. Considered options for building a professional career of boxers, taking into account the experience of performances in prestigious amateur competitions, as well as existing trends of liberalization and globalization of the modern Olympic movement. The individual dynamics of the long-term career of famous male and female professional boxers, who at one time owned championship belts in various weight categories, are presented. The optimal age range for demonstrating the highest sports results in boxing has been determined. The influence of international sports organizations (WBC, WBA, WBO, IBF, etc.) on the formation of sports careers of athletes in professional boxing is analyzed.
Systematized and considered stages of formation of the highest sportsmanship in professional boxing: 1) formative stage of 18-24 years (quantitative intensification of competitive activity); 2) - the stage of optimal opportunities (championship phase) - 25-35 years; 3) the stage of preservation and gradual decline of sports results - 35 years and more. It has been established that men have a longer formative phase of their professional career, which is characterized by a significantly greater number of preparatory matches in the initial stages of its formation and a longer period of time to maintain the achieved results in the final stages of multi-year improvement. The need to take into account the important regularities of the formation of the highest sportsmanship in boxing and the rational logistics of planning matches during the annual training cycle, taking into account the stage of the sports career and the age of the athletes, is substantiated.

Pandesal, as it is already a staple and typical food for Filipinos, is also a product that is constantly evolving. Food commodity deterioration significantly impacts its marketability and inspires the development of profitable new consumer products. The study aimed to test the level of acceptability of pandesal with saluyot (Corchorus olitorius) as a product of UM Digos College. The selected respondents were randomly picked: seventy-five (75) males and seventy-five (75) females from Bagumbayan, Malalag, Davao del Sur. Using descriptive statistics and T-test, utilize mean to determine the level of acceptability of the respondents to the product. The respondents assessments in pandesal were made from 15 grams of saluyot (Corchorus olitorius) powder (x=2.87). This acceptable result was obtained from the acceptable level in terms of taste (x=4.24), texture (x=2.67), color (x=2.90), and aroma (x=2.99). In 30 grams of saluyot (Corchorus olitorius) powder in pandesal was rated by the respondents as the most acceptable level with an overall rating of (x=4.24). This most acceptable result was obtained from the acceptable level in terms of taste (x=4.21), texture (x=4.36), color (x=4.15), and aroma (x=4.25). Pandesal was made from 60 grams of saluyot (Corchorus olitorius) powder (x=3.26). This acceptable result was obtained from the acceptable level in terms of taste (x=3.31), texture (x=3.21), color (x=3.14), and aroma (x=3.37). The result revealed that the respondents rated pandesal with dried saluyot (Corchorus olitorius) leaves with 30 grams in terms of taste, texture, color, and aroma as the most acceptable. Thus, it is recommended that the texture of the dried saluyot (Corchorus olitorius) leaves shall be more refined. Moreover, the researchers recommended pursuing the product since the study revealed that 30 grams of pandesal with saluyot (corchorus olitorius) powder were most acceptable to the respondents. Thus, it can be developed and improved for commercialization.

An overview of the existing methods of measuring static stresses at elevated temperatures, at which it is problematic to use classical strain gauges, and methods of compensating the imaginary temperature deformation was performed. Namely: the use of multi-component alloys, the manufacture of active and compensatory sensitive elements from different alloys, which should theoretically compensate for each other's shortcomings. In practice, this can be sufficiently achieved only in a narrow temperature range. The described primary transducer is a rectangular strain-gauge rosette for measuring static and thermal stresses in structural parts operating under extreme conditions at temperatures up to 700°C. This sensor is a two-layer rosette consisting of two sensitive elements (SE), the main axes of which are rotated relative to each other by 90°. The lower SE perceives the main deformation of the part, and the upper one, located above the lower one, plays the role of a temperature-compensating electrical resistance of the element and simultaneously registers the transverse deformation of the part. SE rosettes were made of a wire with a diameter of 30 microns of the Х20Н80 alloy and fixed to each other and to the part using Ц-165-32А cement. The experimental study consisted in determining the temperature characteristics of the resistance of both the lower and the upper SE of the studied strain gauge associated with the temperature expansion of the part-strain gauge system as well as with the shunting of the insulator-connector and the change in the specific resistance of the SE material. Experimental determination of apparent strain gauge deformation at different temperatures was performed. To determine the influence of the coefficient of linear expansion of the material of the part on the change in the resistance of the SE, strain gauges were attached to samples of various materials. The change in the apparent deformation of the strain gauge in the temperature range from room temperature to 700 °C is shown. Its maximum value for the ceramic sample was less than 350 µm/m, for the 30ХГСА steel sample it was less than 1000 µm/m, and for the ВЖЛ14Н-ВІ alloy sample it was less than 750 µm/m. Dependencies were obtained that allow corrections to be made in the result of a real study of the stressed state of the part to achieve the maximum accuracy of measurements.

The direction of increasing the efficiency of marine power plants by using heat exchange elements that implement intensive methods of heat transfer, which are characterized by a predominant increase in heat transfer over aerodynamic resistance, is considered. The research method is mathematical modeling of processes in power plants at the level of their individual elements – heat engine, power, and technological heat exchangers. The adequacy of the mathematical model for research the efficiency of power plants is justified by the results of verification and validation by comparing the results of calculations with the results of a physical experiment that have a discrepancy not exceeding 9.3 %. The goal of the research is to improve the economic, environmental, resource and weight-size parameters of power plants by using heat exchange elements with the intensification of the processes of convective transfer of heat and mass by using finned surfaces with dimples. Thanks to the performance of dimple systems on the edges of round pipes with spiral-ribbon finning and elliptical pipes with lamellar finning, it is possible to increase the heat transfer coefficient up to 36 %, while the resistance coefficient of the beam remains unchanged. The use of heat exchangers with the proposed heat transfer elements as part of ship power plants with low-speed engines and gas-and-steam turbine units allows to improve their economic and environmental characteristics. It was obtained that for tankers of the PANAMAX type, the increase in the efficiency of the ship's power plant is 1.3 % due to the use of elliptical surfaces with plate finning and hole systems on the ribs in the utilization boiler. The ship's EEDI index decreased by 1.7 %. For container ships with a deadweight of more than 100,000 tons, the change in these indexes was 2.5 and 2.7 %, respectively. For a marine gas-and-steam turbine plant, the efficiency increase was 2.4 %. The presented mathematical model of the power plant is characterized by positive results of approbation for constructive and verification calculations of power plants in marine energy, transport, and industry.

The object of research in this article is the change in the rotor shape during the operation of hydraulic units. The subject of study in this article is the design and geometric state of the shape of a rotor with irregular geometry of hydraulic generators-engines. This study produced a three-dimensional mechanical calculation of the rotor segment for further use during strain gauge tests. Tasks: investigate the peculiarities of the rotor shape restoration technology; to describe the basic assumptions for the three-dimensional mechanical calculation of rotor deformations at the overspeed; and perform a three-dimensional calculation of rotor movements considering the main forces falling on the pole connection, which are obtained using classical methods. The methods used are: finite element method of mathematical modeling of the thermal stress state of nodes. The following results were obtained: a detailed description of the technological process of restoring the shape of the rotor using the hot wedging method is given. Three-dimensional models of the rotor segment were developed, and a three-dimensional mechanical calculation of this model was performed, as a result of which satisfactory values of the displacement of the rotor of the hydraulic generator at the overspeed were obtained, considering the recovery technology. To reconstruct the rotor rim, it is necessary to heat the rotor rim to a temperature difference between the rim and the frame of at least 60 °C. Next, the hot wedging of the rotor rim is performed with the driving of each of the driving wedges by the same amount, which ensures the creation of the necessary diametrical tension between the rim and the frame of the rotor and avoids the displacement of the rotor rim relative to the frame. The control of this process is performed using strain gauges. If necessary, it is necessary to cool the rotor rim until the temperatures of the rim and the frame of the rotor are equal. Conclusions. The scientific novelty consists of a combined approach to the evaluation of the deformation of the rotor rim after restoring its shape, which includes elements of analytical mechanical calculation and calculation in a three-dimensional setting. The presented technology for the rotor restoration process meets European requirements.

Overview So far, measuring the country's development still focuses on economic indicators. Despite the fact that there is still the assumption that there is “better wealth for a better lifestyle,” the concept of measuring well-being is expected to complement current financial metrics.Bio The phial hypothesis explained how environmental conditions affect well-being. Air and water pollution in Indonesia is getting worse and may affect well-being as an indicator of doing right. It aims to explore the impact of sociolect-demographic, economic and environmental characteristics on well-being in Indonesia. The technique used in this test is ordered logit regression. The results show that people tend to be happier when they live in places where they have higher incomes, are married, are in better health, are better educated, have better processes, and have less polluted water and air. I was. Age has a pronounced effect on U-shaped happiness, with the lowest predicted age being 49 for her. An interesting finding, on the other hand, is that the unemployed tend to be happier than the employed. These findings encourage governments to pay special attention to improving well-being statistics, developing non-textiles such as health, education and employment, and strengthening efforts to protect the environment.
