Authors: Minchenko Yulia S. , Shemelina Olga N. , Hadid Mahmoud
Published: December 2023

Relevance. The need to develop new technical and technological solutions to improve the efficiency of water isolation in wells with horizontal termination in reservoirs with layered heterogeneity of the formation. Aim. To identify and propose a promising gel-forming composition for conducting water isolation in wells with horizontal termination in reservoirs with layered heterogeneity of the formation. Object. A well with a horizontal termination in reservoirs with layered heterogeneity of the formation. Methods. Laboratory and bench studies of the gel-forming composition for isolating water inflow in wells with different reservoir permeability by modifying it with functional additives and further adapting its application to various mining and geological conditions of the well; technology of injection of compositions with different viscosity in wells with horizontal termination in reservoirs with layered heterogeneity of the formation. Results. The paper considers the theoretical aspects of a hydrophobic layer formation on a watered reservoir surface effected by a hydrophobic composition, when it enters the reservoir. The paper introduces the mechanism of a water-insulating screen formation during injection of a gel-forming composition. The authors have defined the basic requirements for the gel-forming composition. They developed the formulation of the gel-forming composition with a different gelation time from 1 to 8 hours. Due to the composition injection, a water insulation screen is formed that can withstand significant water flow pressure. The water breakthrough pressure varies and depends on the initial permeability: with an increase in gas permeability from 0.1 to 1 mm2 of the breakthrough pressure it decreases by water and ranges from 4.5 to 11.5 MPa/m.

Authors: Burmistrov Konstantin V. , Osintsev Nikita A. , Rakhmangulov Aleksandr N. , Yusupov Maxim E.
Published: December 2023

Relevance. Long periods of development of steeply dipping deposits necessitate multiple adjustments of mining and technical system throughout an open pit life cycle. The decisions made determine the development strategy of a mining enterprise for a long period. The complexity of making such strategic decisions depends on numerous influencing parameters. These parameters have a different impact, have a variety of units of measurement, target values, and are not only quantitative but also qualitative. There is a need for new approaches to the choice of development strategy of the mining and technical system of an open pit, as well as its main subsystem – the opening-up of an opencast system. It is proposed to base these approaches on multi-criteria decision-making methods that consider many influencing parameters. Aim. Development of a methodology for choosing a strategy for sustainable development of the deep open pit mining and technical system based on multi-criteria decision-making methods and assessment of the opening system parameters. Objects. Mining enterprise, mining and technical systems, opening system. Methods. Literature review, system analysis, multi-criteria decision making.   Results. The authors have determined the main strategies for development of the mining and technical system for deep open pits. These strategies aim at achieving the sustainable development of the mining and technical system: adjustment of the current stage mining parameters; transition to a new stage of mining; transition to a combined open-underground mining; mine closure. The key role of the opening system in the structure of the mining and technical system is substantiated to ensure its sustainable development. The authors systematized the main parameters for evaluating the pit opening system and set target values for each parameter. A review of the main multi-criteria decision-making methods used to solve various problems in the mining industry is made. A rank coefficient is proposed for choosing the mining and technical system development strategy. The calculation of this coefficient is based on a combination of the fuzzy AHP and CRADIS multi-criteria methods. A method was developed for selecting a strategy for sustainable development of the mining and technical system of deep open pits. A case study was conducted on the conditions of the Maly Kuibas open pit. The obtained results strongly suggest that the best strategy with the highest ranking is the transition to the combined development method.

Authors: Lysak Ilya A. , Lysak Galina V.
Published: December 2023

Relevance. Increasing negative effects of hydrocarbon production on aquatic ecosystems and tightening of legislative norms on discharge of oil and oil product contaminated water into marine waters. Among various methods used to remove oil from aqueous solutions the most appropriate one is adsorption method. It is explained by its high degree of purification, safety, availability, manufacturability, universality of application. Synthetic materials based on ultrafine fibers have optimal characteristics for manufacturing sorbents for oil removal on their basis. However, the large-scale application of these materials is limited by their high cost, complexity of manufacturing, which excludes the secondary use of polymers as feedstock. In this regard, there is a growing need for economically and environmentally effective hydrophobic materials for sorptive treatment of aqueous media from oil and petroleum products. Aim. To determine sorption properties of hydrophobic fibrous materials produced via pneumatic formation for use as effective hydrocarbon sorbents for liquidation of oil spills in sea and water treatment on oil production platforms. Objects. Sorbents based on polypropylene and polyethylene terephthalate ultrafine fibers. Methods. Gravimetric, spectral analysis, transmission electron microscopy, gas chromatography. Results. The paper introduces the results of investigation of sorption properties of untreated ultrafine fibers obtained by pneumatic atomization and modified by microwave radiation. The authors have carried out the comparative analysis of water absorption and the influence of contact time and acidity of the medium on the degree of sorption of samples obtained from hydrophobic polymers. Promising application of sorbents based on polypropylene ultrathin fibers for oil products extraction from aqueous media was revealed. It is established that modification reduces water absorption of polypropylene sorbents and leads to an insignificant decrease in sorption properties due to changes in the supramolecular structure of polypropylene fiber samples.
Assignment of initial parameters and boundary conditions for modeling thermal state of underground pipelines in a zone of progression of island permafrost soils
Authors: Filimonov Andrey A. , Strokova Lyudmila A.
Published: December 2023

Relevance. Determined by the importance of predictive modeling of thermal state of pipeline transport facilities located in the permafrost zone. Prediction of geocryological effects is possible through computer simulation of heat and mechanical interactions between a pipeline and a soil medium. Such simulators use data on climatic and geocryological conditions and processes, as well as the information about design and process-dependent parameters of the pipeline, data on its spatial positioning. The presence of various factors influencing heat and mass transfer, as well as the complexity of their numerical simulation, can lead to incorrect design decisions. Such decisions in their turn are always associated with a loss of mechanical safety in an underground pipeline operation. To eliminate this design problem, it is necessary to correctly take into account and adopt the most relevant methods for modeling processes and soil characteristics. Aim. To conduct an analytical comparison of the results of thermal engineering calculations of one section of the route with insular permafrost in order to identify the influence of the model initial parameters on the stress-strain state of the pipeline. Methods. Analyzing the results of engineering surveys for the object of study, conducting a number of numerical calculations, and factorial comparison of the calculation results. Results. At the first stage, the authors have selected the route section of the underground pipeline corresponding to the purpose of the research, the factors influencing the results of thermal modeling. These factors will be considered in this study. At the second stage, the authors carried out modeling of 30 calculation models of one route section with a different set of input data. A factorial comparison of the effect of heat engineering calculation on the results was carried out. At the last stage, the authors carried out the strength calculations of all options for the selected section of the pipeline route as a resulting indicator of the influence of factors.

Authors: Maximov Prokopiy N. , Lokteva Valeria Y. , Kutugin Victor A. , Rudmin Maxim A.
Published: December 2023

Relevance. Development of controlled release fertilisers and their granulation is at the forefront of agriculture and environment. With growing world population and increasing food demand, agriculture faces the challenge of efficient resource management and increased crop yields. In this environmentally friendly and easy to obtain and use fertilisers become a key element for sustainable development of agribusinesses. Aim. To study the complete cycle of creation of granular fertilisers based on new materials, including aggregation of mineral particles with different binding solutions and mechanochemical activation of initial mixtures of glauconite and urea. Potassium-containing clay mineral – glauconite of Karinskiy deposit (Russia) was used as a "container" material. Urea containing up to 46 wt % of nitrogen was used as an additive (nutrient) component for fertilisers. The following parameters were stable during mechanochemical preparation: mineral/urea ratio and abrasion type. Solutions with different nitrogen concentrations were used as binders during granulation. The methodology for investigating the characteristics of the resulting nanocomposites included particle size analysis, X-ray diffraction analysis, scanning electron microscopy, and FTIR spectrometer. Results. The advantages of different granulation options for mechanochemically activated composites were investigated. The authors have produced f full cycle of controlled-release granular fertiliser. The average nitrogen content in glauconite particles reaches 5.5 wt %. The granule size depends on the content of urea gel concentrate in the binder. The maximum strength and proportionality of granules are achieved, when using a binder consisting of 100% urea gel concentrate. Determination of the optimal content of gel concentrate in the binder used in granulation plays a key role in obtaining strong fertiliser granules.

Published: December 2023

Relevance. The need to enhance the precision of electricity consumption forecasting for improving energy efficiency and, consequently, enhancing the competitiveness of manufactured products by reducing the proportion of electricity costs in their total cost. When determining forecast indicators of electricity consumption by industrial enterprises, it is important to apply contemporary high-precision forecasting methods. Only 20–30 forecasting methods of the 150 existing ones are actively implemented in practice. An examination of prevailing forecasting methodologies used by industrial enterprises reveals that they are mainly based either on expert assessments of electricity volumes or on accounting for specific electricity consumption (per unit of product manufactured). Aim. To elevate the accuracy of electricity consumption forecasting at industrial enterprises by using artificial intelligence methods, specifically, artificial neural network techniques, including the Long-Short Term Memory (LSTM) approach. Methods. When developing the forecasting model, artificial neural network techniques were adopted, with a particular emphasis on the Long-Short Term Memory (LSTM) method. For primary data processing, Gaussian distribution principles and normalization/scaling techniques were applied. Results. Substantiated computationally by applying the proposed model based on the artificial neural network technique for forecasting electricity consumption of industrial enterprises. A significant advantage of this method is its capability for learning and adaptability to forecasting. Real-time computations demonstrate its successful implementation, attributed primarily to appropriate selection of input layers and mitigation of random variables.

Authors: KIRBOYUN TİPİ Sevgi
Published: December 2023

This study explored the effectiveness of screen readers on the academic life of higher education students with visual impairments, including reading, writing, access to the internet, exams, and general information for their courses. This study was designed as a qualitative study and applied a phenomenological approach in order to discuss the experiences of higher education students who use screen readers as assistive technology. One college student and six graduate students with visual impairments were interviewed in the United States. The findings revealed that higher education students with visual impairments benefitted from screen readers; however, they also noted some limitations: difficulties in accessing printed classroom materials, inaccessible digital content, and time lost due to technical issues. Students with visual impairments should be offered accessible documents such as electronic versions of classroom materials, accessible PDFs and websites, and software compatible with JAWS. Universities should provide accessibility training for lecturers who want to better serve students with visual impairments. University information technology services need to train their technical services staff about screen readers to provide 24/7 professional services for students with visual impairments.

Authors: KARA-ZORLUOGLU Dilara , OZDİNC Ilkem , KARGA Busra , CEYHAN Gaye
Published: December 2023

Recent research indicates that college students experienced increased stress and academic anxiety during the Covid-19 era. Near-peer mentoring is a program that pairs students in different grade levels with the goal of enhancing their academic, emotional, and social development. This study uses the Expectancy-Value Theory to examine the motivation of pre-service science teachers to participate as mentors in the near-peer mentoring program, and the costs they attach to participating in the program. The qualitative research was conducted with a total of twelve pre-service science teachers. Data were collected through individual interviews during the spring semester of 2021. Results revealed that participants found the program useful, benefited from this program in terms of social/emotional support and academic career, and stated that it would be more beneficial if the content of the program were improved. The participants’ motivation to participate in the near-peer mentoring program were categorized into seven, from the most beneficial to the least, as follows: (1) developing learning strategies, (2) career planning, (3) access to university services, (4) communication, (5) sense of belonging, (6) academic development, and (7) support in registration and course selection. This research carries notable importance as it can strengthen the sense of community among pre-service teachers. This study is likely to provide an opportunity for the design of near-peer mentoring programs in universities and the development of content in accordance with the findings. Furthermore, the insights derived from this study can be crucial in designing and implementing effective near-peer mentoring programs at tertiary education levels, promising mutual benefits for both the mentor and the mentees.

Authors: Bolger Ellen , Crosse Nuala
Published: December 2023

This article will present a reflection on the benefits of a collaborative approach in the field of social work practice education and learning. It will specifically outline how collaborative practice, centered around a practice teacher and their student, was developed in a hospital neurorehabilitation setting. This will be demonstrated via the innovations which took place in establishing a peer support group for a cohort of patients under the age of 65. We will discuss with the reader, our framework which was developed with the intention of promoting an investment by practice teachers, students, field agencies and college educators in taking part in collaborative practice within the education environment. We will outline and reflect on the 3 main principles of our framework for collaborative practice within the realm of social work. These include: 1) Individual Traits, 2) Reflective Practice and 3) Learning and Professional Development. This article will highlight the benefits of embracing a collaborative approach in practice education by focusing on the principles above, within an interdisciplinary work setting.
A Macro Level Reflection on Practice Teaching and Learning from the west of Ireland.
Authors: Kelly Eleanor , Walsh Catherine
Published: December 2023

This abstract, based on a dialogue across practice and academic contexts explores the anomaly that while it is generally acknowledged that social work placements are integral to professional development and are mainly positive experiences for all concerned, practice teaching remains tangential to social work practice resulting in a chronic shortage of placements. 
A valuable model of co-production, the paper draws on systems theory to assess and analyse the ongoing precarious situation of placement places in Ireland.  
The issue is very topical and has potential to generate further discussion and future research.
How the COVID-19 pandemic both hindered and promoted professional development in social work student placements: findings from Ireland’s Child and Family Agency’s evaluation of students and practice teachers.
Authors: Owens Stella
Published: December 2023

The onset of the pandemic in March 2020 resulted in the sudden disruption and severe impact of student social work placements in Ireland. The Child and Family Agency responded innovatively to the crisis and facilitated final year students to complete their placements remotely through the provision of ICT equipment to ensure these students graduated on time. Subsequent placement provision in the Agency has risen significantly since September 2020. To measure and assess the impact and quality of practice placements in the Agency, Student and Practice Teacher Feedback Questionnaires were disseminated to the January 2021 cohort. Student (N=99) and Practice Teacher (N = 85) feedback reported a high degree of satisfaction with both the student and practice teaching experience. Student respondents repeatedly referenced how practice teachers, despite the pandemic, provided opportunities to increase skills and confidence in social work practice. Students described being supported and guided by knowledgeable, skilled practice teachers. Practice teachers developed new skills in mentoring, supervision, case management and prioritisation of cases. They embraced the opportunity to engage in reflective practice, to build on the theoretical perspectives and latest practice developments that students bring from third level courses and to enable students to link theory to practice in a concrete and coherent way.  The primary challenges for practice teachers centred on time management-especially regarding supervision, workload balance, and working remotely during Covid-19 restrictions. For both students and practice teachers limited opportunities to engage in face to face, relationship based practice with families was particularly difficult.
Holistic practice, art, creativity and the politics of recognition
Authors: Froggett Lynn
Published: December 2023

A strand of social work thinking that insisted on the art-like nature of practice has been marginalised in recent years by a scientistic and technical-rational turn. This has been consolidated by a number of interrelated factors including competence-led education, managerialism, the audit culture and the building of a scientific evidence-base. Within healthcare, however, the arts and humanities are flourishing and are thought to nourish professional creativity and artistic dimensions of practice. Social work has much to learn about professional creativity from the arts for health movement, but a detailed understanding of the ways in which such practice contributes to well-being has yet to be developed. The paper draws on current research in a cross-professional community and healthy living centre where the creative process is seen as central to organisational and personal development. Art, broadly conceived, is understood as a special instance of creative living: story-telling, poetry, drama, music and visual arts underpin most of the Centre’s activities and services. The paper explores ways in which this facilitates the development of a rich internal symbolic life within the organisation which supports experimentation and creative illusion. Staff and users are encouraged to find and use media which foster a distinctively personal creativity and in the process develop an ability to oscillate between analytic and syncretistic modes of perception. This supports a practice based on interpersonal recognition and directed at an integrated conception of health, social care, education and leisure. A complex view emerges of the relationship between creativity and recognition and its importance for personal development which is an irreducible element of wider struggles for recognition in institutional and societal domains. A practical understanding of this link is strengthened through narrative, biographical and other creative methodologies, which by virtue of their holistic view, can help to counter an overly procedural practice.
Direct payments and the social model of disability
Authors: Glasby Jon
Published: December 2023

Despite learning about the social model of disability in social work training, it is difficult to see how new workers can apply this model in practice in a care management system that seems so service-rather than needs-led. Against this background, the advent of direct payments is a major opportunity to promote choice, control and independent living at the heart of twenty-first century social care. While direct payments can seem like a challenge to the role and professional expertise of qualified social workers, they are a unique chance to deliver genuine empowerment and personcentred, needs-led approaches in a system that all too often does not let its workers strive to achieve these goals.

The article looks at the ramifications for social work which is based on a social model of madness and distress; what it might look like and what infrastructural supports it is likely to require to develop effectively.
Creativity, fantasy, role-play and theatre in social work
Authors: Uggerhøj Lars
Published: December 2023

This article considers the development of social work research and social work practice. In contrast to the usual emphasis on evidence based studies and tools in social work research the article argues for the development of quantitative studies and tools and proposes creativity, fantasy, role-play and especially Forum Theatre as key elements of this development. This approach is compatible with Flyberg's 2002 concept of ‘actual science’ – a context-dependent methodology oriented more towards subjects than objects – or ‘phronetic social science’ – where judgements and decisions are based on values. Both approaches have the capacity to incorporate the complexity of social work, to involving users and social workers in research processes, and to build up knowledge production from the bottom up. The article also argues that creativity, role-play, fantasy and Forum theatre are as necessary and useful in developing social work practice as in facilitating the research process.

Authors: Hervey Nick
Published: December 2023

This paper describes the journey of a social services manager taking on the development of an over-arching user involvement strategy within an integrated mental health service. It highlights the introduction of a framework for user involvement which has proved able to adapt to successive policy initiatives including the Health and Social Care Act, Changing the Balance of Care, Patient and Public Involvement, and most recently Personalisation. It discusses some of the challenges, but also the real benefits of meaningful service user involvement. It also suggests that managers with a social care background are uniquely positioned to take on such a development.

AIM

The aim of this study was to evaluate the outcomes of the patients who underwent OCF fixation and simultaneous MPFL reconstruction after patellar dislocation in children.

MATERIAL AND METHOD

A total of 12 patients who underwent OCF fixation and simultaneous MPFL reconstruction between 2018 and 2021 were retrospectively evaluated. Demographic information, surgical specifics, and clinical follow-up data were gathered. Postoperative clinical assessments were conducted utilizing Kujala and Lysholm scores.

RESULTS

The mean age at surgery was 10.4 years (range, 7-15 years). The mean period of follow-up was 36.5 months(range, 24-58). One (8%) patient required a second surgery on the ipsilateral knee. The mean surface area of the fragments was 2.5 cm² (SD: 1.4). Preoperatively, the Kujala score and the Lysholm score were 38.2 (SD: 13.3) and 44.1 (SD: 10.4), respectively. These scores exhibited significant improvement postoperatively, reaching 87.6 (SD: 11) and 88.2 (SD: 10.3) at the latest follow-up. Radiological examinations, including X-ray and MRI, indicated favorable healing of the OCFs.

CONCLUSION

Osteochondral fracture fixation in children with patellofemoral instability can be effectively managed through fixation combined with simultaneous medial patellofemoral ligament reconstruction. The mid-term results have demonstrated satisfactory outcomes.
El derecho humano al agua potable y al saneamiento ¿utopía o realidad?
Authors: Miranda Gonçalves Rubén
Published: December 2023

Atualmente, existe uma disparidade mundial com relação à qualidade e disponibilidade da água que torna impossível seu acesso e usufruto por todas as pessoas. Embora seja verdade que o direito humano à água e ao saneamento tenha sido reconhecido em 2010 e que a Agenda 2030 o considere como um dos seus ODS, ainda é necessário estabelecer mecanismos legais que apoiem este direito e que, principalmente, o tornem exigível. Neste contexto, é necessário refletir sobre como conciliar o valor econômico da água com a responsabilidade de garantir que este recurso vital esteja ao alcance de todos.
A prática musical do flamenco como forma de interação: aspectos performáticos da “cena” musical do flamenco no Brasil
Authors: Pancrácio Micael
Published: December 2023

O estudo da performance com foco nos aspectos não verbais da prática musical evidencia a existência de elementos sociais que permeiam a atividade musical e os processos de interação entre indivíduos. Essas experiências de engajamento musical, cujas interações físicas podem não se interligar por meio de mediação linguística, flexionam discursos para além de uma camada interpretativa, em que gestos e formas não verbais de comunicação possuem aspectos corporificados diante dos significados atribuídos aos sons musicais. A investigação etnográfica realizada na “cena” do flamenco no sudeste brasileiro demonstrou que as relações sociais por meio da música (BLACKING, 1973), estabelecidas por meio do domínio léxico de elementos não verbais de interação musical, bem como da construção de discursos musicais improvisados em contextos performáticos apresentacionais (TURINO, 2008), possuem uma estreita relação com a construção de uma narrativa fundamentada em um pensamento local de “autenticidade performática”. Esse pensamento, vinculado ao contexto das performances interativas e ao domínio da linguagem musical do flamenco, medeia e estabelece as relações entre seus indivíduos, destacando aspectos de translocalidade, (re)construção de significados e formas particulares de engajamento social. Este artigo busca apresentar, portanto, por meio de excertos etnográficos recolhidos na “cena” do flamenco no Brasil, uma análise sistemática e reflexiva desses elementos não verbais de interação musical, bem como das relações que se estabelecem entre o domínio dessa linguagem e a construção local de um pensamento de “autenticidade performática”.

Digital health interventions for managing Non-Communicable Diseases, specifically cardiovascular diseases, are gaining momentum in Low-Middle-Income countries (LMICs), notably in the South-East Asia region. The effective implementation of these interventions hinges on their ability to effectively cater to user needs within the healthcare system. Our objective is to examine the usage of digital health approaches or modalities. A scoping review was conducted using PUBMED and SCOPUS databases, and the findings were synthesized narratively using the WHO’s Digital Health Intervention (DHI) framework. The initial search yielded 1,505 articles, of which 51 met our inclusion criteria. In terms of the target users for digital health applications, providers remain the major focus, while other stakeholders such as data managers and health system managers remain neglected. Even within “provider-focused” applications, telemedicine dominates in the functionality aspect. Further, few applications addressed client issues such as client-to-client communication, personal health tracking, and the client’s financial transactions. Few applications address the needs of data managers and health system managers. Moving forward, member countries in South-East Asia would benefit from digital health applications that specifically target data services and health system managers. For clients, functionalities such as personal health tracking, active data capture, citizen-based reporting, on-demand information services, and peer groups are required. For healthcare providers, features such as access to longitudinal client health records, decision support systems, referral coordination, prescription, and medication management, as well as laboratory and diagnostic imaging management, should be seamlessly integrated into existing digital health applications.

В роботі розглядаються принципи використання мультимедійних засобів навчання в різних освітніх середовищах. Досліджується вплив мультимедіа на процес навчання у традиційних класичних навчальних ситуаціях, дистанційних курсах та віртуальних навчальних оточеннях. Розглядаються основні принципи ефективного використання зображень, звуку, відео та інших мультимедійних компонентів для забезпечення кращого розуміння та запам’ятовування навчального матеріалу. Дослідження спрямоване на з’ясування оптимальних підходів до інтеграції мультимедіа в навчальний процес залежно від контексту навчання.
Аналізуються різноманітні методи та стратегії використання мультимедіа для стимулювання активності студентів, покращення їх здатності до критичного мислення та сприйняття інформації. Додатково досліджується роль інтерактивних елементів мультимедіа, таких як віртуальні лабораторії, симуляції та інтерактивні завдання, у сприянні активному навчанню та засвоєнню матеріалу.
Аналізуються виклики та переваги використання мультимедіа в різних навчальних контекстах, таких як традиційні лекції, онлайн курси, віртуальні класи та інші. Обговорюються можливі обмеження та пастки, пов’язані з перенасиченістю інформацією та відволіканням від основного навчального завдання.
Також розглядається питання доступності мультимедійних матеріалів для людей з різними видами обмежень (наприклад, зі зниженим зором чи, навіть, відсутністю слуху), а також методи забезпечення інклюзивного навчання за допомогою мультимедіа.
Висновки дослідження допоможуть визначити оптимальні підходи до впровадження мультимедіа в різні навчальні сценарії та сприяти покращенню якості навчання та розумінню навчального матеріалу студентами.
Дослідження процесів утворення мікрорельєфних напрямних на профільних пластинах для фальцювання інтегральних обкладинок

Об’єктом дослідження є процеси формування мікрорельєфних напрямних на профільних пластинах для фальцювання інтегральних обкладинок. Проведено аналітичні та експериментальні дослідження зосереджено на вивченні механізмів утворення мікрорельєфів та їх впливу на точність та ефективність фальцювання.
Основне припущення дослідження полягає у тому, що оптимізація мікрорельєфних напрямних на профільних пластинах може значно покращити якість фальцювання обкладинок, забезпечуючи більш точний контроль над процесом та зменшуючи механічний знос інструменту.
Вивчено вплив різних параметрів мікрорельєфних напрямних, включаючи їх глибину, ширину та кут нахилу, на процес фальцювання. З’ясовано, що застосування поверхневої обробки з нанесенням мікрорельєфу на профільні фальцювальні пластини підвищує їх зносостійкість, оптимізує просторову профільну геометрію та знижує швидкість зносу, підвищуючи ефективність інструменту.
Виявлено, що ефективність мікрорельєфних напрямних залежить від типу матеріалу обкладинок. Налаштування параметрів фальцювання відповідно до характеристик палітурних матеріалів забезпечує оптимальні результати.
Результати дослідження можуть бути використані для розробки нових технологій у виробництві профільних фальцювальних пластин, що підвищує якість кінцевого продукту.
