Authors: Kantová Nikola Čajová , Čaja Alexander , Belány Pavol , Kolková Zuzana , Hrabovský Peter , Hečko Dávid , Mičko Pavol
Published: February 2022

Various waste materials have energy potential. It is important to make use of this potential and prepare the product for further use by treating the waste. Treatments such as compressing waste into pellets leads to increasing the energy density of this fuel, which benefits transport and storage costs. However, low bulk density, high ash content, low-ash melting temperatures, and low calorific values of non-woody pellets can cause problems during their combustion. This article deals with the energy usage of walnut shells, which were blended with spruce sawdust in various amounts and compressed into pellets. The mechanical and energy properties of these were measured and compared with recommended or standardized values. The formed pellets met the quality limit for bulk density, ash content, moisture content, the content of nitrogen and sulfur, and net calorific value according to ISO 17225. However, low ash melting temperatures were noticed for pellets from pure walnut shells, and also lower mechanical durability for produced pellets with walnut shells contents higher than 10% were detected.
Development of a loop-mediated isothermal amplification (LAMP) assay based on the C962R gene for african swine fever virus detection
Authors: Kit M. , Schwarz J. , Gerilovych A.
Published: February 2022

Aim. The aim of this study was to develop a loop-mediated isothermal amplification (LAMP) assay for African swine
fever virus (ASFV) detection. Methods. Primer design was performed using publicly available full genome sequences
of ASFV. A panel of heterologous DNA samples and reference ASFV DNA samples were used for the assay specificity
testing. The limit of detection (LOD) was assessed using purified and quantified serial dilution of the amplified target
sequence. LAMP product detection was performed via gel-electrophoresis and via ethidium bromide fluorescence
under UV after adding the ethidium bromide directly to the tube with the LAMP product. Results. Three primer sets
amplifying different regions of ASFV gene C962R were developed, of which the set № 2 providing the most intense
product synthesis with the most vivid and clear pattern was selected for further studies. The optimal concentration of
reaction mix components for the most effective primer set was established. In the final protocol the LAMP reaction
was carried out at 60 °C for 40 min. The limit of detection (LOD) of the assay was 50 copies of the target sequence
per reaction. In a preliminary testing the assay proved specific, using 10 reference and 4 heterologous viral and two
bacterial DNA samples. Our LAMP assay detected ASFV genotypes I and II that are currently spread in Europe, Asia,
and the Pacific and IX, occurring in Africa. Conclusion. A LAMP assay was developed based on the C962R gene that
proved in preliminary validation to be specific and sensitive and was able to detect down to 50 copies per reaction of
purified target gene within 40 minutes. Classical gel electrophoresis and direct staining using ethidium bromide were
used for product visualisation in this study. Colorimetric approaches or the use of lateral flow devices in the visuali-
sation step could make the assay less equipment dependent. Further validation of the assay, determining analytical
specificity, selectivity and reproducibility performance characteristics also using clinical samples under field condi-
tions and inclusion of an internal control would possibly enable its use as a test of choice at point-of-care and at low
resource laboratories.

The decentralization reform in Ukraine has resulted in creating the primary level of the administrative-territorial system – territorial communities (TC). Rural settlements are also included in TCs, consisting of more than 25 and even 50. Today, TCs as administrative entities face the challenge of uniting communities and preserving and developing their people. The purpose of the paper is to substantiate the necessity and principles of TCs inclusive development, identify the situation of their rural communities referring to the example of Lokachynska TC, and test approaches to assessing their involvement in the functioning of the community. The following research methods were used: dialectical and abstract-logical (in the analysis of threats to rural communities due to their merger in the TC and justification of their inclusive development principles), monographic (to characterize Lokachinskaya TC), economic and statistical (in assessing the level of inclusive community development). It has been proven that one of the tasks of amalgamating territorial communities, especially those that include too many rural settlements is ensuring development based on inclusiveness. The TCs’ development and their rural communities aimed at reducing poverty, overcoming the economic, social, and political exclusion of people living in rural areas providing them with the opportunity to have a tangible impact on their lives is defined as inclusive development. The main characteristics of Lokachynska TC and the conditions of its rural communities’ functioning are revealed. Following the determining methodology of the rural sector of social inclusiveness, which is adapted to the community level, the involvement of Lokachynska TC communities in the economic, social and socio-political spheres was assessed. The study results can be used in strategies and plans for developing territorial communities, considering the specifics of community in each settlement, and identifying overcoming ways of its economic and/or social exclusion.

Published: February 2022

The reorientation of Ukrainian vacationers to the domestic tourist market due to the COVID-19 global pandemic has created additional demand for specific types of tourism, among which green tourism occupies a vital place. At the same time, although it is easy to find acceptable options for green recreation, there are still many controversial and uncertain points in this area of tourism. The article is devoted to the study and comparison of expert opinions with actual analytical data to form a system of measures to enhance the development of domestic green tourism. The methods of economic-statistical modelling, dialectical and abstract-logical methods, bibliometric analysis, graphic method of scientific research are used in work. The article considers the work and approaches of scientists and international organizations to determine the nature, subjects and specifics of green tourism. With this in mind, our approach to interpreting the definition of “green tourism” has been formed. The author presents the analytical data on the effectiveness and directions of green tourism the potential number of tourists focused on green recreation. Expert opinions on the prospects and problems of green tourism development in Ukraine are presented. Emphasis is placed on the available tools of state regulation of the studied sector and the international practice of green tourism regulation. Considering all the above, the problematic factors that cause the most significant deterrent effect on the development of domestic green tourism have been identified in the author’s opinion. Using the methods of economic and statistical modelling, the relationship between thevolume of capital investment in tourism and the profitability of tourist services is proved. The system of measures proposed by the author to increase the investment attractiveness of green tourism in Ukraine is substantiated and presented. The need to improve the quality of green tourism in Ukraine was emphasized.

Published: February 2022

The purpose of the study is to provide a comparative analysis of democratic leadership effectiveness in the relatively large presidential and semi-presidential countries of the world. Providing powerful political leadership is the essential task for presidents and institutions of the presidency in presidential and semi-presidential democratic republics. Countries with presidential and semi-presidential systems of government should be combined under the term “countries (states) with the executive presidency or presidential states (countries)” that reflects their common feature, namely: critical role of the institution of the presidency. Two main indicators of political leadership effectiveness in democratic states are the EIU’s Democracy Index (DI) and comparable GDP (PPP) per capita that reflect the current situation and comparative dynamics in the political and economic fields of societal development. The United States confidently hold economic leadership in the group of polities with an executive presidency, but the DI in this country during the last 15 years has steadily declined. In the subgroup of presidential republics, three Latin American states – Uruguay, Chile and Costa Rica – have noticeably outranked the United States (and South Korea) by the EIU’s DI. The experience of Chile deserves attention: there had been a dramatic upsurge of social unrest in late 2019, but the Chilean president, Sebastián Piñera, and his government took the political initiative and led the process of changing the constitution successfully. In 2020 the semi-presidential Republic of China (Taiwan) had been the absolute leader in political development and economic growth among the states with an executive presidency. The president, Tsai Ing-wen, played a crucial role in implementing and realizing democratic leadership there. Lithuania is the apparent leader in democracy and economic improvement among the European semi-presidential states during the last two decades. The next research of the author in this direction will be devoted to the comparative institutional analysis of the presidency functioning in the United States and Ukraine as the sample countries with presidential and semi-presidential systems of government systems respectively at the present stage of development.

Published: February 2022

Soil arthropods respond sensitively to land management practices and correlate with beneficial soil functions. The aim of this research was to determine soil quality using the QBS index in different types of crops and influence of soil variables (pH soil, soil moisture, potassium, phosphorus and nitrogen) on soil arthropods. Between the years 2018 and 2020, we studied different types of crops (Brassica napus, Pisum sativum, Triticum aestivum, T. spelta, Zea mays, Grass mixture and Hordeum vulgare) and recorded 14 taxa. Our results suggest a higher QBS index value in crops grass mixture, Pisum sativum, Triticum aestivum, T. spelta. The EMI value grew with increasing values of soil moisture, soil pH, phosphorus, potassium and nitrogen; indicating the presence of soil arthropods occurring in higher quality soil. Our results suggest that agricultural intensification affects soil arthropods, which are important for the production of biomass, which also affects crop yields.
Meander reshaping – the formation process of a wintering riverbed depression of fish
Authors: Chemagin A. A.
Published: February 2022

The study of the spatiotemporal distribution of fish is an important and poorly studied aspect of the ecology of aquatic organisms. The research work was performed using the modern hydroacoustic method and geographic information systems. A section in the lower reaches of the Irtysh, a large transboundary Siberian river (in Western Siberia, Russian Federation), was studied. It has a strong development of meandering. The merging (i.e., reshaping of closely spaced meanders and erosion-accumulating channel processes) results in development of wintering riverbed depression, which is a critical “temporal bottleneck” during the winter period of the fish life cycle. The average density of fish in the study area in summer and autumn was 8,031 and 9,194 individuals per ha, respectively. Analysis of the distribution of fish showed that the distribution in the horizontal aspect had a more aggregated character in the autumn. In the vertical aspect, it had a more surface (pelagic) character. The ichthyofauna in the water area of the riverbed depression is mainly represented by cyprinids. The loop-shaped evolution of the channel formed a section of the river with multidirectional, circulating, and counter-current flows. It also created zones with depths exceeding 20 m and aggregations of fish. These features characterize the studied water area as a wintering riverbed depression of the fish of the Lower Irtysh. This section of the river should be included in the list of protected wintering biotopes of fish in the West Siberian fishery basin, which will ensure the conservation of fish at the critical stage of the life cycle.
Water vole (Arvicola amphibius) as an object of long-term biomonitoring in a floodplain area (Western Siberia, Russia)
Authors: Ilyashenko V. B. , Luchnikova E. M. , Kovalevsky A. V.
Published: February 2022

The paper is devoted to the dynamics of the water vole population in the conditions of total deforestation of valley forests and their subsequent restoration. We analyzed the relative population of small mammals in the typical biotopes in the Tom River basin (Western Siberia) on the border of the forest-steppe and taiga zones. From 1978 to 2019, 1,139 water voles Arvicola amphibius (Linnaeus, 1758) (synonym of A. terrestris) were caught with 50-meter trapping grooves; for 788 individuals we assessed the condition of non-metric features (phenes) of the skull. It was found that changes in the population level are non-cyclical, while against the background of a generally low occurrence of the species in the region, the population level increased tenfold in some years. It was shown that such episodic population surges can significantly impact the structure of the community of small mammals. In the valley of the Tom River, the water vole prefers inhabit wet meadows and ecotone areas between the meadow and the dark coniferous taiga forest. During the years of population surges, the water vole intensely occupies new nesting sites due to the dispersal activity of young animals but at the same time retains the original biotopic preferences. Dispersal of the species takes place in waterlogged wetlands. Most of the animals caught during the peak of their numbers were young animals of late broods born from overwintered individuals. The conducted phenetic analysis revealed the heterogeneity of young animals during the population surge, which allowed us to assume the participation of several populations in the formation of the peak. In the final surge year, the surge was characterized by an extremely low percentage of participation in the breeding of young females and the appearance of a large number of weakened animals, which led to crisis in the species population and the disappearance of the water vole from the captures. The research shows that one cannot predict the success of this process at the current stage; therefore, after flooding, it is necessary to continue monitoring.

Neuromyelitis optica spectrum disorders are autoimmune disorders of the central
nervous system marked by inflammatory demyelination, axonal loss and astrocytopathy,
associated with lesions in the brain and in the spinal cord and with the presence of
antibodies against aquaporin 4 (AQP4-IgG). Various studies on neuromyelitis optica
spectrum disorders broaden the knowledge about their immunopathogenesis, clinical
course, immunological assays, and magnetic resonance imaging findings. Nevertheless, in
clinical practice differential diagnosis remains challenging, particularly in cases
seronegative for AQP4-IgG. Essential clinical syndromes in neuromyelitis optica spectrum
disorders, namely optic neuritis and acute myelitis, could also be observed in multiple
sclerosis and other demyelinating diseases of the central nervous system. The early and
accurate diagnosis is essential due to different prognosis and treatment strategies in
these diseases. For example, therapies used in multiple sclerosis, including
beta-interferons, natalizumab, fingolimod and alemtuzumab, may not only be ineffective
in neuromyelitis optica spectrum disorders but even harmful and provoke relapses.
Therefore, in a patient with a clinical neurological syndrome accompanied by
demyelinating lesions in the central nervous system several investigative studies should
be undertaken, including serological assays [AQP4-IgG, antibodies against myelin
oligodendrocyte glycoprotein (MOG-Ab)], the cerebrospinal fluid examination and magnetic
resonance imaging of the brain and spinal cord, and interpreted with caution. Due to
clinical similarities and relatively common misdiagnoses, there is a need to summarise
the typical and atypical clinical, laboratory and radiographic features in neuromyelitis
optica spectrum disorders to avoid diagnostic pitfalls and inappropriate
treatment.
A contemporary review of non-invasive methods in diagnosing abdominal aortic
aneurysms
Authors: Sauceda Ana
Published: February 2022

Background: Currently, the impact of abdominal aortic aneurysm may be changing
despite the aging population, but may be ambiguous given the decline in smoking, the use
of screening methods, and integration of non-surgical treatment. Objective: This review
aimed to assess the most common currently used non-invasive methods to identify
abdominal aortic aneurysm, namely ultrasound and computed tomography. Methods: PRISMA
guidelines were utilized to retrieve original articles from the past five years. All
retrospective and prospective studies/trials were included, but limited to US and CT
abdominal aortic aneurysm diagnostic imaging methods. Qualitative assessment of study
quality is described. Results: Three of the six studies reported abdominal aortic
aneurysm screening data. The estimated prevalence of abdominal aortic aneurysm for the
three studies ranged from 4.5% to 6.2%. CT had slightly higher sensitivity and US had
higher specificity for abdominal aortic aneurysm diagnosis. Two of the described studies
assessed technical issues and problems with contemporary imaging of abdominal aortic
aneurysm. The final article described measuring abdominal aortic aneurysm function of
aortic distensibility and its pulse wave velocity for a comprehensive assessment of the
abdominal aortic aneurysm via standard CT imaging. Conclusions: Both US and CT are
useful diagnostic imaging modalities for abdominal aortic aneurysm, but remain with
unique pitfalls and propensity for errors, notwithstanding patient-related errors.
Technical issues in imaging with both ultrasound and CT are not straightforward. The
potential value of an integrated CT protocol with CT-US fusion and/or assessment of
aortic function rather than solely aortic anatomy may further diminish diagnostic
complexities.

Aim: The study aimed to evaluate the usefulness of contrast-enhanced ultrasonography in renal perfusion disorders caused by obstructive uropathy. Case description: We present a case of a patient with a horseshoe kidney, in which the urine outflow from the right part of the kidney was blocked due to the presence of a bladder tumour infiltrating the ureter. Perfusion disorders in both parts of the kidney, visible in computed tomography, were partially reflected in the ultrasound image. Conclusions: Doppler ultrasound and contrast-enhanced ultrasound may be useful for monitoring perfusion disorders in the course of obstructive uropathy, provided that appropriate methodology is developed to compare blood flow in both kidneys.

Aim of the study: Trisomy 13 is the third most common autosomal trisomy. The following case report shows an atypical case of trisomy 13, highlighting the usefulness of 3D volume storage and reconstruction, and the necessity of careful interpretation of the first trimester screening results. Case description: The results of the first trimester screening tests were interpreted as normal, and invasive tests were not recommended. At 21 weeks, a bright spot in the left ventricle was noted, and fetal echocardiography was performed at 33 weeks. The scan showed a massive pericardial effusion and a pericardial tumor located in front of the right ventricle. Conclusions: The final diagnosis, made postnatally, revealed an atypical right-sided diaphragmatic hernia. Part of the liver was displaced to the pericardial cavity, mimicking a pericardial tumor in a baby with trisomy 13. Following the diagnosis of the lethal disorder, the baby was discharged under a home-based palliative care program and died on the 49th day of life.

Authors: Utami Putu Sri , Ani Luh Seri , Lubis Dinar Saurmauli , Wirawan Dewa Nyoman
Published: February 2022

Background and purpose: Anemia in women is a public health concern that is prevalent in developing countries. Women of reproductive age (WRA) frequently suffer from anemia, which can contribute to morbidity and mortality of mothers and their infants. The purpose of this study was to determine the prevalence and factors associated with anemia among women of reproductive age (WRA) in Indonesia.Methods: This study uses secondary data from the 2018 Indonesia Basic Health Research or Riset Kesehatan Dasar (Riskesdas) which was conducted in 34 provinces in Indonesia. The number of samples analyzed was 3,677 women aged 15-49 years who had data from interviews, measurements of height, weight, results of malaria tests, and hemoglobin levels. Data analysis was performed using multivariate logistic regression to determine the relationship between anemia and individual characteristics, nutritional and health status as well as environmental conditions and health service accessibility.Results: The prevalence of anemia among WRA in Indonesia was 25.3% (95%CI: 23.9-26.7). Factors which found to be associated with the prevalence of anemia in WRA were age <20 years (AOR=3.44; 95%CI: 2.22-5.35; p<0.001), underweight (AOR=1.48; 95%CI: 1.08-2.05; p=0.017), obesity (AOR=0.68; 95%CI: 0.56-0.81; p<0.001) and the use of hormonal contraception (AOR=0.53; 95%CI: 0.44-0.64; p<0.001). Conclusion: Based on the prevalence, anemia among WRA in Indonesia is categorized as a moderate public health concern and the most common risk factor for anemia was WRA aged <20 years and underweight. To reduce the incidence of anemia in WRA, interventions should be targeted at WRA aged <20 years and underweight.

Published: February 2022

Background and purpose: Mother-to-child transmission of HIV has been one of the problems in HIV prevention. In Indonesia, private practice midwives (PPM) play an important role in maternal and child health services. The roles of PPM in HIV vertical transmission prevention through PMTCT have not yet clearly understood. This research aims to analyse the roles of PPM in Bali Province in the PMTCT program as well as the PPM’s characteristics, knowledge, and attitudes about the program.Methods: This study was a descriptive cross-sectional survey, conducted from March to May 2020. The study population was PPM in Bali Province. The samples obtained were 404 out of a total of 1,736 PPM (23% response rate). The variables studied included socio-demographic characteristics, services and resources characteristics, knowledge, attitudes, and the role of PPM in four PMTCT prongs. Data was collected via self-filled online questionnaires distributed through Indonesian Midwives Associations branches in every district/city in Bali Province. Data were analysed descriptively and differences in roles in PMTCT were analysed using the chi-square test.Results: Of the 404 PPM, 66.1% served childbirth (deliveries), 25.4% had served HIV-positive women, and 18.3% had served HIV-positive pregnant women. As many as 95.5% of PPM played a good role in prong 1, and 99.0% of PPM, who had served HIV positive patients, played a good role in prong 2, 3 and 4. Statistically significant determinants for good implementation of prong 1 of PMTCT by the PPM were indicated by ownership or access to PMTCT information media (p=0.026), experience of serving HIV positive women (p<0.00), and having served higher number of PMTCT patients (p=0.019).Conclusion: The PPM in Bali Province has played a good role in PMTCT, with a significant difference for good PMTCT implementation in prong 1 determined by the availability of information media, a history of serving HIV-positive women, and the number of PMTCT patients who have been served.

Published: February 2022

The COVID-19 pandemic is currently the most significant public health emergency worldwide and has impacted many sectors, including in Indonesia. The number of COVID-19 cases in Indonesia has continued to increase since the first case identified on 1 March 2020. The massive impacts of COVID-19 pandemic are not merely related to the fast transmission of the disease itself, but also with the fast spread of various information, both accurate and inaccurate, which have raised confusion in the community. The epidemic of information, which is called “infodemic” is defined by World Health Organisation as too much information including false or misleading information in digital and physical environments during a disease outbreak.

Background and purpose: Cervical cancer is the second most prevalent cancer in women after breast cancer. Nationally, the coverage of cervical cancer screening among reproductive age women from 2014 to 2018 only reached 7.34%, while in Badung District was 10.3% in 2018. In the era of the Universal Health Coverage (UHC) schemes, cervical cancer screening has been covered. This study aims to explore factors associated with the utilization of cervical cancer screening programs in the UHC era in Badung District.Methods: This cross-sectional study was conducted from January-February 2020, involving 195 women aged 20-50 years who were selected through multistage random sampling from two villages in the Badung District. Characteristics of the women, perceptions of seriousness, vulnerability, barriers and benefits, self-efficacy, cues to action and knowledge on cervical cancer screening programs were assessed. Data was analyzed descriptively, and association was assessed with Chi square and multiple logistic regression.Results: The proportion of reproductive age women who utilized cervical cancer screening program in the last 5 years was 44.1%. The utilization of cervical cancer screening program was associated with age (AOR=0.03; 95%CI: 0.03-0.300), perceived vulnerability (AOR=28.77; 95%CI: 3.745-221.68), perceived barriers (AOR=55.70; 95%CI: 7.12-435.72), self-efficacy (AOR=34.44; 95%CI: 4.34-273.66), cues to action (AOR=19.56; 95%CI: 3.32-115.24).Conclusion: The perception of barriers was found to be significantly associated with the use of cervical cancer screening programs along with other variables related to the Health Belief Model (HBM). Structured campaigns and improvement of the quality of services should be carried out in order to increase access of women to cervical cancer screening.

Background and purpose: Fall prevention is an essential part of patient safety system. At Tabanan District Hospital (BRSUD Tabanan), incidence of falling among patients is still happening. This study aims to determine the relationship between level of knowledge and workload of nurses with compliance in implementing standard operational procedures (SOP) to prevent the risk of falling in the inpatient rooms at Tabanan District Hospital.Methods: This study was a cross-sectional survey. The sample size was 75 nurses in the inpatient room at BRSUD Tabanan. Data collection was carried out in the period of December 2, 2019 - January 2, 2020 which included 1). direct interviews to obtain data on characteristics, the level of knowledge and workload of nurses, 2). observations of nurses' adherence in the implementation of standard operational procedures to prevent the risk of falling patients. Data analysis was performed by univariate, bivariate with chi-square test and multivariate analysis with logistic regression.Results: Most of the respondents were ≤40 years old (86.7%), female (72%), length of working ≤10 years (81.4%), education level of bachelor in nursing (65.4%). Two third of the respondents have a good level of knowledge (66.7%), with medium workload (26.7%) and heavy workload (73.3%). Most of the respondents (70.7%) adhere to the implementation of standard operating procedures to prevent the risk of falling patients. Variables associated with the compliance to SOP are age (AOR=5.35; 95%CI: 1.230-23.259; p=0.025), level of knowledge (AOR=6.409; 95%CI: 1.720-23.873; p=0.006), and workload (AOR=0.076; 95%CI: 0.17-0.339; p=0.001), where the workload variable has a negative relationship with nurse compliance (AOR<1).Conclusion: The conclusion of this study is that there is a relationship between the level of knowledge and workload on nurses' compliance in implementing standard operational procedures to prevent the risk of falling patients.

Purpose of the work. Obtaining predictive regression models, by means of which, it is possible to adequately calculate the mechanical properties of monocrystalline nickel-base superalloys without conducting previous experiments.

Methods of research. For experimental and theoretical studies of temperature performance, a working sample of alloys is formed consisting of known industrialt nickel-base superalloys for monocrystalline castings of domestic and foreign production, which due to contents of the main elements, cover a wide range of alloying. The obtained values were processed in the Microsoft Office with the least squares method, with the obtaining of the "parameter-property" correlation dependencies with the obtaining of mathematical equations of regression models (trend lines) that describe these dependencies optimally.

Received results. The influence of alloying elements on their tendency to the formation of phases in foundry heat-resistant nickel alloys is considered. Based on the influence of elements on phase formation, the coefficient of the ratio of alloying elements Kg¢ in the alloys of this class was first developed.

A close correlation dependence of the ratio Kg¢ with a dimensional discrepancy between the γ- and γ-phases crystalline lattice (localized) was found. It has also been shown that for multi-component nickel systems it is possible to predict with high probability misfit, which significantly affects the strength characteristics of alloys of this class.

The regression models of correlation dependencies on dimensional inconsistency (γ / γ'-misfit) are given, which allow to predict the boundaries of short-term and long-term strength of alloys. It is shown that the magnitude of the misfit at the operating temperature should tend to zero. This will increase the structural stability by minimizing structural stresses, which has a positive effect on the strength and plastic characteristics.

Scientific novelty. For the first time, a coefficient of the ratio of alloying elements Kg¢, which has a close correlation with the strength and dimensional discrepancy of casting nickel-base superalloys, is proposed.

Practical value. The perspective and effective direction in solving the problem of forecasting of the main characteristics affecting the complex of service properties of alloys, both in the development of new monocrystalline nickel-base superalloys, and in the improvement of the composition of known industrial brands of this class, is shown.

Purpose. To perform comparative studies of structural features and mechanical properties of test steel for railway wheels with microalloy complex Al + N + Ti and known steel for high-strength railway wheels of brand T, microalloyed with vanadium.

Methodology. Microstructural, micro-X-ray spectral and X-ray phase analyzes were used to determine the structural state of the alloys.

Results. Comparative analysis of the structure and mechanical properties of steels for high-strength railway wheels of brand T and K + Al + N + Ti. It is shown that in K + Al + N + Ti steel after crystallization the structure becomes finer-grained and increase in the volume fraction of perlite was observed in comparison with steel of T brand. It was found that the HPD leads to the decrease in the volume fraction and size of oxides, and in aluminum oxides Al2O3 there is a partial replacement of aluminum atoms by iron and titanium atoms.

Originality. It is shown that the reduction of vanadium content in steel and complex alloying with aluminum, titanium and nitrogen leads to the formation of the finer-grained structure and increase in the volume fraction of fine perlite. In the microstructure of K + Al + N + Ti steel, the formation of oxides, nitrides and carbonitrides was observed, which were located along the grain boundaries and in the body of the perlite grain.

It was shown for the first time that HPD leads to the fact that in the inclusions of aluminum oxides Al2 O3 the partial replacement of aluminum atoms by atoms of iron or titanium, with the formation of oxides of Fe2(Al)O3 and (Al, Ti)2O 3, take place.

Practical value. The use of complex alloying of steel leads to improvement of mechanical properties: increase in toughness at the high level of hardness and strength of steel grade K + Al + N + Ti in comparison with steel of brand T.

Published: February 2022

Purpose. Investigate the mechanism of forming the profile of the machined surface when milling with a tool with a long overhang.

Methodology. Experimental method was used with a special stand, which makes it possible to simulate an elastic system of a part with different dynamic properties, record oscillograms of oscillations of a part and a tool during the cutting process. Milling was performed with a milling cutter with cutting modes in which self-oscillations occur. To determine the patterns of movement of the part and the tool, the method of aligning the fragments of oscillograms was used.

Results. The scheme of the formation of the profile of the machined surface under the conditions of milling with self-oscillations by a tool with a long overhang has been investigated. It was found that the free vibrations of the tool after the tooth leaves the cutting zone have a higher intensity than that of the part. This affects the position of the infeed point on the cutting surface. To determine the period and range of self-oscillations of the cutter and the part, the section of the oscillogram with self-oscillations was straightened using the Savitsky-Galei filter. Comparison with the cutting surface of the sections of the oscillogram of the part and the tool during milling showed an identical vibration mode of the cutter. Based on the results of experimental studies, the deviation from the line of elastic equilibrium of the first wave of self-oscillation of the cutter was determined and a graph of its change was plotted. The studies performed have confirmed the previously established effect of deviation from the elastic equilibrium position of the first self-oscillation wave during counter milling on the shaping of the treated surface.

Originality.  It has been established that the profile of the machined surface when milling with long overhang end mills is directly related to the deviation of the tool from the elastic equilibrium position during self-oscillation.

Practical value. The obtained results show the effect of a tool with a long overhang on the formation of a machined surface during milling with self-oscillation.
