In this article, the residual resource of a centrifugal pump was anticipated, which operates an overestimated resource in the pumping line of a nuclear power plant. The results of theoretical and numerical modeling of its stress-strain state with a change in the geometry of the hull parts are presented. Three-dimensional FE models have been developed that take into account the actual geometry of pump parts, as well as a forecast of their possible changes during further operation. The change in the geometry of the structure is taken into account on the basis of extrapolation of data on the thickness of the hull walls obtained over a long service life. Calculations to determine the static strength are made for the main operating mode of the pump (under normal operating conditions). In places of welds, the cyclic strength was checked separately, while taking into account the decrease in their strength due to an increase in equivalent stress amplitudes by dividing them by the coefficient of reduction in the strength of the weld. The process of thinning of the wall of the pump housing under the action of erosive-corrosive wear is modeled. This process is random, so it was modeled taking into account the equations of wear growth kinetics. As a result of the research, the damage parameter and the probability of failure-free operation of the structure were obtained. These parameters are determined taking into account the predicted values of the percentage thinning of the pump housing wall and the obtained characteristics of the statistical deformation state of the structure.

Authors:   National Technical University “Kharkiv Polytechnic Institute”, SMOLIN Yurii
Published: February 2023

The directions of development of control as a scientific branch are considered. It is shown that the variety of definitions of control goes beyond terminological inconveniences and hinders communication of specialists and their creative search, and this necessitates the development of a single approach and a single terminology in the theory of control. A detailed analysis of the existing views of experts on control, the results of their discussions and changes in approaches to terminology that existed in previous years and have developed at this time. The analysis of literature sources on the problems of definitions and terminology of technical control is given. Most of the existing dictionary definitions of control and technical control, as well as their modern interpretations are given and analyzed. There are two main forms of technical control: passive and active control. The terminology related to passive and active control is considered and analyzed, taking into account the methods after operational and technical control. It is shown that the universality and capacity of the term control contributed to its penetration into various spheres of human activity, including technology. Control is defined as a generic concept, and this interpretation for the needs of quantitative research has been translated into mathematical language in terms of set theory. An isomorphic mathematical model of the physical model of the object of control is given, in which the nature of the object of control is not specified, ie it can be technical, economic, biological, etc. The parameters of technical objects of control of the corresponding offered model are also given. It is shown that in terms of control capabilities the main interest is its methodological component, which expresses the essence of control, determines its specific varieties. The results of control of technical and other objects as the necessary information base of this or that production procedure are considered: rejection, sorting, protection. It is proved that when the control results are used to control the technological object, in this case it is not the control of the source object, but the controlled process and the process itself is now the object of control, but not the object of control. Thus, the more developed form of participation of control in management of technological object is its active control.

Proper nutrition of Ukrainians is one of the most important problems of today, which shapes the health and well-being of the nation as a whole. In a rational diet a special role is played by the creation of new, balanced in composition products that are enriched with deficient functional components – minerals, vitamins, dietary fiber. Analysis of the publications of domestic and foreign scientists shows the relevance of such a direction of creating new functional products as expanding the range of multicomponent stuffed mass with a variety of raw materials of animal and vegetable origin. According to scientific studies, the value of yield strength (YS) in the case of a change in the moisture content of minced sausages by 1% changes by 10… 15%, while the numerical values of other properties (viscosity, elasticity) change slightly. Thus, yield strength is a parameter by which you can effectively control the quality characteristics of minced meat. Fat retention capacity (FRC) is a technological characteristic that is important during all stages of the technological process of production of finished meat products and semi-finished products and is the ability of the system to adsorb fat balls on the surface and convert some fat into bound state. The ability of minced meat to bind moisture strongly depends on the degree of dispersion of the particles and the moisture-binding capacity (MBC). According to theoretical studies, taking into account the traditional trends of Ukrainian cuisine, the authors chose the main mass components to create minced meat with poultry and vegetable hydrobionts, these were – minced chicken, boiled beans and onions. The aim was to study an important rheological characteristic of minced meat – changes in the YS of dispersed systems, to create multicomponent stuffing. The aim of the study was also to determine the patterns of changes in MBC and FRC three-component model systems during the introduction of different concentrations of components. The paper presents the results of experimental studies of rheological and physicochemical properties of dispersed systems for creating minced meat with poultry and plant aquatic organisms. The dependences of the main rheological indicator for the stuffing system – the yield strength. Data on the moisture-binding and fat-retention capacity of the three-component polydisperse system were also obtained. Changes of the specified indicators from change of a parity of components are investigated.

Analysis of wheat yields over the past 20 years shows that wheat yield are growing in all regions of Ukraine. This is a result of the growing investment attractiveness of the grain industry and the significant investments made in the industry. However, the upward trend is accompanied by significant fluctuations in wheat yields, which are mostly caused by weather and climatic factors. The most noticeable is the climatic factors influence for the steppe regions of Ukraine. The paper proposes a classification approach to forecasting wheat yield taking into account weather and climatic factors and the use of machine learning methods. A set of wheat yield data in four regions of the steppe zone of Ukraine for the period 2000-2021 and the corresponding values of 12 meteorological factors were used to build computer models. Cross-validation with division into 10 groups was used to build and test of models. Numerical values of wheat yield were converted into a binary variable, which acquires only two values: “0” (low yield) or “1” (high yield). If the value of wheat yield exceeding over the trend value is greater than the specified threshold value, the new value of binary variable is 1, otherwise the binary variable value is 0. Two models are constructed to classify the excess of yield over the trend value, which are based on the regression logit and regression probit. The obtained model values can be interpreted as the probability of a significant excess of yield over the trend value. Both models provide high quality classification with a slight advantage of the logit model. The aggregate classification quality of both models exceeds 88%, which is a good result for such a complex task as modeling the dependence of yield on meteorological factors in a small sample.

Minimization of thread tension during processing on technological machines allows to reduce the probability of breakage in the working area. This is achieved by optimizing the geometric parameters of the thread feed system on process equipment, namely obtaining such a broken thread shape, in which the total angle of coverage of structural structural elements of process equipment in the form of cylindrical guides and torus, elements of tensioning devices will have a minimum value. This will reduce the amount of friction between the thread and the guide surfaces and get the minimum tension in the working area. Given the large number of structural elements of the thread feed system on technological machines, their location in the plane and space, there is a need to use modern information technology. Implementing this requires the use of algorithms and computer programs to find the optimal path of the graph using the Dijkstra algorithm. Determining the tension and changes in relative tension in the refueling zones of technological machines, taking into account the specifics of the design of the thread feed system, will reduce thread breakage, optimize t Improving the process of thread processing on technological machines of light industry is to minimize tension and should be based on theoretical and experimental studies of the interaction of threads with structural elements of the feed system, including tensioning devices, breakage control and guides of large and small curvature. Imperfect shape of the thread filling line on technological machines of light industry, low quality of complex threads and yarn with increasing tension along the depth of filling leads to their breakage.hread tension in the working area of the source product.

Objective: In this study, the authors seek to investigate the relationship between cognitive impairment and fear of COVID-19. Among the residents of Tehran Province, Iran, 415 people were selected through the available sampling method. Methods: The research data was obtained through online questionnaires that were distributed to participants via platforms, such as Instagram, WhatsApp, and Telegram. Broadbent’s cognitive failure questionnaire and the scale of fear of COVID-19 were used in this study. The obtained data were analyzed by the independent t test and stepwise regression. Results: According to the findings, the relationship between following COVID-19 news and the fear of COVID-19 is negative. Also, a positive and significant relationship exists between memory error and fear of COVID-19. Also, the standard coefficients show that despite the direction of the effect, both variables have the same power to change the dependent variable. Conclusion: The findings showed that the subscale of memory (forgetfulness) predicts the fear of COVID-19, and the existence of memory problems, false triggering, and distractibility, which are components of cognitive failure, decrease individuals’ mental health.

Objective: Depression and anxiety are common in children and a major cause of many illnesses and disabilities in this age group; Moreover, parents have the greatest impact on shaping the mental health and well-being of their children and there is a vast literature describing the importance of parenting factors in the development of depression and anxiety in children. Methods: We used the experimental research design in this study. The sample consisted of 34 children with depression and anxiety who were randomly allocated into ACT on parenting (intervention) and control groups via the randomization method. The intervention group received eight 2-h sessions weekly. The revised child anxiety and depression scale, parent short versions and the self-compassion scale were administered in both groups. The analyses of covariance (ANCOVA) and the repeated measures of analysis of variance (ANOVA) were employed to determine the difference between the intervention and control groups on depression, anxiety, and self-compassion. Results: ANCOVA and repeated measures ANOVA results showed clinically significant changes in depression and anxiety in children and self-compassion in parents in the intervention group (P<0.001). The Mean±SD of depression in the intervention group was 16.50±0.89 at baseline, which significantly decreased to 2.94±3.27 at post-measure and 2.25±3.35 at follow-up (P<0.001). The Mean±SD of anxiety was 18.19±1.87, which significantly decreased to 7.63±4.34 at post-measure and 7.06±4.52 at follow-up (P<0.001). Additionally, the mean and SD score of self-compassion was 56.43±3.14 in pre-intervention, which significantly improved to 97.18±3.72 in post-intervention and 98.25±4.76 at follow-up (P<0.001). Conclusion: The results show that ACT-based parenting is an effective treatment for depression and anxiety in children. This method also improves self-compassion in parents.

Objective: The present study defines the experiences of childhood sexual abuse (CSA) and aims to explain its relationship with satisfaction with married life and sexual performance in Iranian married women. Methods: The statistical population included all married women in Tehran Province, Iran, in 2021 in the age range of 18 to 50 years. According to the study population, 200 people were selected as the sample using the available sampling method and answered the female sexual function index, developed by Rosen et al. (2000), the marital satisfaction questionnaire by Enrich (1989), and the unwanted childhood sexual experiences questionnaire by Stevenson (1998). In the statistical method, the research hypotheses were tested according to the normally distributed research variables, using the Pearson correlation coefficient and multivariate regression. Results: The results of the Pearson correlation showed a negative and significant relationship between the experience of CSA and satisfaction with married life, along with the two components of sexual pain and sexual desire in the variable of sexual performance (P<0.01). In addition, the multivariate regression results showed that CSA experiences could predict marital life satisfaction. However, only the component of maximum contact in the CSA variable predicted the components of sexual pain and sexual desire in the sexual performance variable (P<0.01). Conclusion: The experience of CSA in Iranian married women can affect their marital relationship and sexual performance. Accordingly, efforts should be made to identify these people and consider appropriate psychological measures for their recovery because, in Iranian culture, most people hide this incident out of social shame and fear of being dishonored.

Cybervetting and the Public Life of Social Media Data
Authors: Gruzd Anatoliy , Jacobson Jenna , Dubois Elizabeth
Published: February 2023

The article examines whether and how the ever-evolving practice of using social media to screen job applicants may undermine people's trust in the organizations that are engaging in this practice. Using a survey of 429 participants, we assess whether their comfort level with cybervetting can be explained by the factors outlined by Petronio's communication privacy management theory: culture, gender, motivation, and risk-benefit ratio. We find that respondents from India are significantly more comfortable with social media screening than those living in the United States. We did not find any gender-based differences in individuals' comfort with social media screening, which suggests that there may be some consistent set of norms, expectations, or "privacy rules" that apply in the context of employment seeking-irrespective of gender. As a theoretical contribution, we apply the communication privacy management theory to analyze information that is publicly available, which offers a unique extension of the theory that focuses on private information. Importantly, the research suggests that privacy boundaries are not only important when it comes to private information, but also with information that is publicly available on social media. The research identifies that just because social media data are public, does not mean people do not have context-specific and data-specific expectations of privacy.
