Study of Temperature Gradients in Concrete Products in the Process of Their Heat Moisture Treatment

Statement of the problem. The work is devoted to the problem of improving the technological process of production of concrete products, in particular, improving the performance of the stage of their heat and moisture treatment. As such indicators, the spatial and temporal temperature gradients in the thickness of the concrete product are chosen, the excess of which exceeds the maximum allowable values for this type of concrete and adversely affects the strength of the product. On the other hand, steam-moisture treatment of products with obviously low values of these gradients leads to an increase in the time of the considered stage of the technological process, i. e. to reduce line performance. In this regard, the task was set to quantify the temperature gradients in the sections of concrete products in the process of their heat and moisture treatment by using the appropriate mathematical model. Results. As a result of studies carried out on the model of temperature fields in the longest mode — cooling mode, a significant uneven distribution of temperature at the boundaries of the «concrete-air» media was shown and critical zones of these fields in the sections of products and time intervals of their existence were identified. Conclusions. A conclusion was made and confirmed on the expediency of reducing the temperature in the chamber according to the exponential law and on the need to control its gradients in the critical sections of products.

Effect of treatment with original or biosimilar adalimumab on SARS-CoV2 vaccination antibody titers

The technological process of production of biosimilars determines the degree of biosimilarity to the original biological drug. In particular, the focus is on the similarity of immunogenic responses. The primary endpoint of our retrospective study was to find the differences in SARS-CoV-2 antibody amount between patients treated with original adalimumab and biosimilar adalimumab MSB11022 (Idacio) and the differences in the SARS-CoV-2 antibody amount between patients treated with and without biological treatment. We collected the gender, autoimmune disease type, age, and treatment data of the patients in the outpatient clinic MEDICAL PLUS, s.r.o., Uherske Hradiste. These patients suffer from autoimmune rheumatic diseases. All patients received the mRNA vaccine (Pfizer/BioNTech – BNT162b2), with a 21-day (interquartile range, 21–24) gap between the two vaccinations. Patients receiving adalimumab were able to develop cellular immune responses after the second vaccination dose, as well as the individuals without adalimumab. In the period of 6–23 weeks after the second vaccination dose (D63 – D182), the SARS-CoV-2 antibody levels did not change significantly in the patients receiving the original adalimumab, while in the patients receiving biosimilar adalimumab a significant decrease was revealed. A statistically significant difference in the SARS-CoV-2 antibody amount between the patients without biological treatment (median: 504.3 U/mL) and with biological treatment (Original and Biosimilar – median: 47.2 and 28.2 U/mL, respectively) was confirmed on day 182. According to our observation, the effect of the treatment type on the increase/decrease of antibodies over time is dominant, while the impact of other variables (gender, methotrexate treatment, autoimmune disease type, and age) was confirmed as insignificant or minor.

КОМПЕТЕНТНОСТЬ СПЕЦИАЛИСТОВ ЖЕЛЕЗНОДОРОЖНОГО ТРАНСПОРТА В ОБЛАСТИ ЗДОРОВЬЕСБЕРЕЖЕНИЯ

The priority of safety issues in ensuring the uninterrupted and accident-free movement of trains, the safety of cargo, the life, health, well-being of passengers and railway workers allows us to consider measures aimed at maintaining health, preventing occupational diseases, developing professionally significant physical, psychological and personal qualities enshrined in regulatory documents defining the procedure for professional inspections in railway transport as part of the technological processes of railway production (Development Strategy of the Russian Railways Holding for the period until 2030; section 5.5. Social block). An increase in information flows, changes in the organizational, logistics, technological, and technical foundations of transport production give rise to situations of high variability and danger. This challenge significantly increases the level of influence of risks of various natures, the implementation of which can lead to socially unfavorable consequences (the occurrence of errors, failures, failures, threats to the safety of cargo, the health and life of workers and passengers). This challenge actualizes the problem of developing the health care competence of railway transport specialists, which belongs to the universal competencies of the “Self-development and selforganization” category. Analysis of scientific and methodological literature and the results of applied research made it possible to summarize the essential characteristics of the concept of “health-preserving competence” and define it as an integrative personal education, the structure and content of which depends on the conditions for the implementation of professional activity, the main functions, actions and operations of the professional activity of specific specialists. The structure of the health-saving competence of railway transport specialists is represented by a set of components: motivational (readiness and attitude towards the implementation of competence), cognitive-activity (knowledge, cognitive skills, practical experience, level of physical fitness and psycho-emotional stability), reflective (self-analysis, selfdevelopment, formation of the self - concept). The logic of forming health care competence can be represented by a movement from a threshold level to a basic level and from there to a higher level - progressive.

Quality ensuring of welded joints of aircraft parts made by electron beam welding using of high-performance machining

This paper presents an assessment of the possibility of creating permanent joints of titanium alloys VT20, OT4-1, performed by electron beam welding with a minimum level of defects due to the use of high-speed machining. The correlation of the defect level of welded joints made by electron beam welding was revealed, depending on the type of mechanical preparation of the joined edges for welding. It is established that the roughness parameter evaluating the surface quality of the joined edges for welding is not correct. A rational way to assess is the saturation of capillary-condensed moisture. It is established that mechanical processing using low spindle speeds and cutting speeds provides the lowest saturation index of capillary-condensed moisture due to thermal processes, which leads to the minimization of pore formation. The obtained research results were tested at PJSC "UAC", KnAAZ named after Yu.A. Gagarin and can be recommended in the technological process of production of titanium power elements of aircraft performed by electron beam welding.

Mathematical modeling of food production technological processes in a computer training complex for operator education

A computer training complex (CTC) structure has been designed for training food production operators, comprising interconnected subsystems generating output parameters. This CTC structure enables the configuration and storage of knowledge on specific technological processes, facilitating the customization of exercises by instructors. Individualized exercises are generated for students to perform in a virtual production environment, utilizing computer programs, tablets, smartphones, or simulated production equipment, including VR/AR technologies.

This model serves as the basis for constructing specific technological process models in the food industry, tailored to CTC hardware, software, and training methodologies. The methodology presented streamlines the development of training courses for CTC exercises, enhancing personnel knowledge and skills in food production. By utilizing these models, methods, and algorithms, CTCs can be tailored for training operators in diverse food production sectors. The approach outlined simplifies course creation, ensuring personnel development at the desired proficiency level through exercise quality assessment algorithms.

FEATURES OF THE FORMATION, INTAKE AND DISTRIBUTION OF THE IRON-CONTAINING COMPONENT IN THE WATER SUSPENSION OF THE DNIEPER RIVER WITHIN ZAPORIZHZHIA CITY

The article presents the results of research devoted to one of the aspects of environmental issues, namely: the determination of the distribution features of the solid component of the river suspension containing iron oxide; investigation of the morphological characteristics of iron-containing particles; and the discovering of their genetic affiliation to various technological processes of metallurgical production. The results of many years of continuous comprehensive research on the distribution of iron in the suspended matter of the Dnieper water within Zaporizhzhia city are presented. Field observations were carried out by scientists of the Institute of Geological Sciences of the National Academy of Sciences of Ukraine (IGS) in cooperation with specialists from the State Institution “Scientific Hydrophysical Center of the National Academy of Sciences of Ukraine” (SHC). Analytical studies of the solid phase of the suspended matter were done in the Center for Collective Use of Scientific Equipment of the National Academy of Sciences of Ukraine and the Educational and Scientific Institute “Institute of Geology” of Taras Shevchenko Kyiv National University. The publication considers the seasonal features of the distribution of the total iron content in suspension and the relationship of its monthly changes with the distribution of concentrations of such heavy metals as copper, chromium, nickel, zinc. Considerable attention is paid to the examination of iron-containing particles present in suspension, their chemical and trace element composition and the allocation of their individual categories in accordance with the technogenic processes during which they were formed. Comprehensive analysis of suspension samples made it possible to identify and classify a group of typical iron-bearing formations that are inherent in the territory of Zaporizhzhia city. Based on a set of characteristics, three main genetic categories have been identified: spherical mineral aggregates represented by iron oxide; clastic fragments of Fe2O3, and aluminosilicate spherules (formation, the main or essential component of which is aluminum oxide with an admixture of iron). The obtained data showed a significant influence of the metallurgical industry on the chemical composition of the Dnieper suspension within Zaporizhzhia. Comparison of iron-containing particles observed in the Dnieper suspended matter with the substance filtered out by gas purification systems of various parts of metallurgical production and slag deposits showed that the most active emission to the environment occurs during the preparation and smelting of iron ore.

Development of buckwheat groats production technology using plasma-chemically activated aqueous solutions

The result of the conducted research is the development of a technology for the production of buckwheat groats using plasma-chemically activated aqueous solutions. The research object was buckwheat grain. An urgent technological problem is the preservation of biologically valuable components of buckwheat during technological operations and optimization of the existing technology for the production of buckwheat groats. The expediency of using plasma-chemically activated aqueous solutions as an intensifier of the technological process of production of buckwheat groats and an effective groats disinfectant has been experimentally proven. It is shown that the use of plasma-chemical activation of technological solutions allows reducing the temperature and accelerating the course of hydrothermal treatment of buckwheat grain. The composition of buckwheat grain as a raw material was analyzed. The obtained buckwheat groats were studied separately. A reduction in tempering time from 6–10 to 2 h and a decrease in the optimal moistening temperature from 60 to 40 °C were recorded. This allows preserving a number of biologically important components in buckwheat grain. The groats yield increases from 68 to 74 %, i.e. by 1.9–6.0 %. The preservation of the maximum number of amino acids is observed, namely, 7.7 % more than in the control. That is, only 2 % is lost during technological processing, instead of 9.7 % in the control sample. The vitamin composition also remains stable and almost does not decrease in terms of B1, B2, B3, B4, B5, B6, K, E, PP, R. In addition, plasma-chemically activated solutions qualitatively disinfect grain raw materials during processing, which has a positive effect on further storage of buckwheat groats. The technology can be applied in the industrial production of high-quality buckwheat groats. The developed technology will receive special attention in the production of ecologically clean cereal products that are not contaminated with pathogenic microflora

The Development and Adaptation of a Predictive Model of Full-Factor Optimisation of the Basic Probiotic Fermented Dairy Product Technological Process

Introduction: In the conditions of rapidly developing markets and the increasing needs of the population for new types of products with long shelf life, there is a need to expand their range, further improve their quality and biological value, and modernize traditional technologies. The main means of achieving these goals is to increase the efficiency and quality of scientific research and accelerate the introduction of scientific achievements in industry. The latter will make adjustments to accelerate the development of effective technologies of whole-milk products. The use of new methods of experiment planning in order to optimize technological processes will reduce the duration of research on the creation of new types of products.Purpose: The article is devoted to the research related to the development and adaptation of a predictive (mathematical) model for optimization of the technological process of probiotic fermented dairy product production. This approach will allow to ensure the design of a certain set of formulations for probiotic fermented dairy product, in which the relative biological value (RBV) will correspond to the maximum value at satisfactory given process parameters.Materials and Methods: The objects of research were: probiotic fermented dairy product manufactured in accordance with the developed mathematical model of the process. The search of specialized literature was carried out using electronic databases: E-library, Scopus, MDPI, Science Direct. Mathematical processing of experimental data for the development of the probiotic fermented dairy product model was carried out using Microsoft Excel 2010 (Microsoft Corporation, Ink.) with the "Solution Search" add-in, as well as specialized software packages TableCurve 2D v.5.01 (SYSTAT Software, Ink.) and Wolfram Mathematica 10.2 (Wolfram Research, Ink.).Results: A mathematical model for optimization of the technological process of probiotic fermented dairy product production was developed. A full-factor experiment (FFE) was conducted, in which the mass fraction of sucrose ( , %) and fat-protein index (r) - the ratio of the mass fraction of fat to the mass fraction of protein in the normalized mixture in the intervals from 0 to 10 and from 0 to 1.5%, respectively, were taken as independent factors. RBV was taken as the resultant factor. Based on the results of the research, a refined mathematical description of the dependence of RBV indicator on the mass fraction of sucrose and fat-protein index was obtained. The set of data on the influence of the mass fraction of sucrose on the dynamics of local maximum of RBV and the dynamics of the corresponding values of the mass fraction of fat showed that the maximum of RBV equal to 244.866% corresponded to the mass fraction of sucrose equal to 7.31%. The latter corresponded to the optimum fat-protein index of 1.241. In order to ensure maximum RBV, the lower limit of the mass fraction of fat had to correspond to 3.475%. The analysis of the FFE data showed the presence of additional corrective factors of RBV indicator dependence on fat and protein mass fraction indices. To refine the developed model taking into account additional factors, a correction factor (Q) was introduced into it.Conclusion: Approbation of the optimization model of the technological process of probiotic fermented dairy product production and the obtained mathematical dependencies can serve as a criterion for the formation of a set of formulations for the production of sugar-containing fermented dairy products with a high potential of relative biological value. It should be taken into account that the definition area of this approach is limited in terms of mass fraction of fat in the range from 0.06 to 4.84% and mass fraction of protein - from 2.8 to 3.9%. With this approach (model development) it is possible to analyze promising modes for the studied process, which in real conditions at the experimental stage are not always possible to obtain. The development of this model will significantly reduce the duration of research on the optimization of the technological process.

Sustainable Strategies for the Recovery and Valorization of Brewery By-Products—A Multidisciplinary Approach

The prevention of environmental pollution is a current concern of the population, which is looking for ways to reduce the production of industrial waste. The brewing industry generates huge amounts of waste, with difficult management from an economic point of view. The waste obtained from the technological process of beer production is used in various branches, such as the food industry, mainly as feed, additives, or food ingredients; as animal feed; in biofuel production; and in building or packaging materials. The valuable by-products obtained from brewery waste can serve as raw materials for further processing or become functional ingredients for the production of new functional products. Reusing and recycling are essential strategies for transforming waste into new valuable resources, and such strategies enable circular solutions to maintain the value of products and resources for as long as possible. The chemical composition of the waste obtained from beer manufacturing can vary slightly depending on the type and quality of the ingredients used and the prevailing conditions during each stage of the manufacturing process. This paper focuses on sustainable strategies for the recovery and valorization of brewery by-products. Experimentally, the aim was to determine the chemical characteristics of different types of brewery waste, such as moisture content, ash, pH, total content of phenolic compounds, and total protein content. The experimental values obtained have shown that brewery waste is a valuable by-product.
