Moving Stillness: Cinema, Temporality, and Life in Settler Capitalist Ruins
Authors: Schiwy Freya
Published: February 2025

abstract: This article contemplates slow cinema's potential to counter the intensity of mainstream eco-disaster cinema. Although the genre's aesthetics are not inherently critical of the temporality of late capitalism, documentaries such as La isla y los hombres (The island and the men, Iñaki Moulian, 2017) can make apprehensible how the epistemological boundary between human and nonhuman life is both partially responsible for ecological catastrophe and linked to settler colonialism. What I call moving stillness invites viewers to sense Indigenous survivance with its multiple temporalities and ways of living on a diminished planet.
"The Keeper of the Flame": Dunya Mikhail's Wartime Laments
Authors: Schmermund Elizabeth
Published: February 2025

Abstract: This article analyzes contemporary Iraqi-American poet Dunya Mikhail's work through a historical analysis of female poets and the lament genre of poetry within the Middle East. I argue that Mikhail draws on the work of early female poets in order to ritually mourn not only those lost during the 1991 and 2003 Gulf Wars but also Iraq's attacked cultural heritage. This article builds upon a feminist analysis of Mikhail's poetry and suggests a deeper analysis of these texts can illustrate not only how women's Arabic-language texts have been misconstrued by Western audiences but also how Arab women's roles within warmaking have often been elided or misconstrued as well.
Aphasia in Andrei Bely's Petersburg
Authors: Zolotareva Olga
Published: February 2025

Abstract: This essay is interested in how a novel behaves when it has been theorized out of existence by its own creator. I take as my case study the novel Petersburg , whose author, the prominent Russian modernist Andrei Bely, criticized the arts (including the art of literature) on ethical grounds. I argue that the tension between Bely's theory and his practice manifests in his text as a form of aphasia, or impaired speech. Reading Petersburg alongside Roman Jakobson's writings on aphasia and Emmanuel Levinas's conception of aesthetics, I argue that the novel yields insight into the behavior of the medium that is conscious of its own ethical limits.
A nyári visszaesés (summer setback) jelenségének empirikus vizsgálata 9. évfolyamos szakképző iskolások körében
Authors: Csíkos Csaba , Katona Miklós , Somogyi Krisztina
Published: February 2025

A számolási készség az oktatási rendszerben fejlesztendő alapkészségek egyike, melynek mérésével, fejlődésével, fejlesztésével kapcsolatban bőséges hazai előzményekre támaszkodhatunk. Kutatásunkban a szakiskolai tanulmányaikat gyakran hiányos tudással és kedvezőtlen családi-kulturális háttérrel megkezdő 9. évfolyamos tanulók vannak a középpontban. A nemzetközi szakirodalomban régóta, ám itthon eddig még empirikusan nem tesztelt nyári visszaesés (summer set back) a külföldi eredmények szerint súlyosabban érinti a hátrányosabb helyzetű tanulókat. Vizsgálatunkban egy váci szakképző iskola 9. évfolyamos tanuló vettek részt (N = 91). Az online mérőeszköz több részből áll: a számolási készség mellett a szöveges feladatok megoldásának színvonalát és a problémaalkotás képességének egyik összetevőjét mértük. Két mérési időpontban ugyanazt a tesztet töltötték ki a tanulók: először júniusban, ezt követően szeptemberben, a következő tanévben. Eredményeink szerint nem történt jelentős visszaesés a plafon-effektushoz közeli eredményességet produkáló tanulók teljesítményeiben. A teljesítmények átrendeződése ugyanakkor detektálható: a két mérési pont adataiból készített pontdiagram az egyéni fejlődési utak markáns megjelenését mutatja. Közepes és pozitív hatásméret melletti fejlődés volt megfigyelhető a problémaalkotás részteszten.
(Nem) gondolkodom, tehát ChatGPT-zek?

Published: February 2025

A mesterséges intelligencia rohamos fejlődésének köszönhetően annak használata az élet minden területén egyre elterjedtebbé válik. Fontos azonban kiemelni, hogy bár a mesterséges intelligencia sok esetben megkön�- nyítheti az életünket, és lerövidíthet egyes munkafolyamatokat, viszont nem képes helyettesíteni egy az egyben az embert és az emberi gondolkodást. E gondolat mentén ugyan az egyetemi hallgatók számára a ChatGPT mint segítő „tollnok” jelenthet támogatást a számos kötelezettség és a szoros határidők miatt. Azonban előfordulhat, hogy az egyetemi hallgatók arra használják a ChatGPT-t, hogy az helyettük készítsen el egy írásos munkát. Mindezek mentén kutatásunk célja a plagizálással és a ChatGPT-vel kapcsolatosan egyetemi hallgatói attitűdök feltérképezése volt, és vizsgálatunkat a kvantitatív kutatási paradigma felhasználásával, kérdőíves formában végeztük el (n = 235). Az eredmények azt mutatják, hogy a kutatásban részt vevő hallgatók kevésbé hajlamosak a plágiumra, és viszonylag közömbösen állnak ChatGPT-hez, viszont felismerik a mesterséges intelligencia potenciális veszélyeit is. Emellett kapcsolatot találtunk a ChatGPT-használati hajlandóság, valamint a plagizálásra való hajlandóság között is.

Exploring the Role of Game-Based Learning in Early Childhood Cognitive Development: Perspectives from Teachers and Parents
Authors: Hibana Hibana , Rahman Nayla Muthia , Nurhayati Kulsum
Published: February 2025

Game-based learning is increasingly recognized as an effective approach to fostering cognitive development in early childhood. This study examines how it enhances children's problem-solving, memory, and attention, as well as teachers' and parents' perceptions of its implementation. Using a qualitative case study approach, data were collected from 20 teachers and 15 parents through semi-structured interviews, classroom observations, and document analysis. Thematic analysis revealed that game-based learning promotes cognitive development by encouraging active engagement, fostering curiosity, and improving problem-solving and information retention. Teachers highlighted the importance of designing meaningful play experiences, while parents observed improvements in children's focus and memory. However, challenges such as inadequate teacher training, limited play resources, and low parental awareness hinder optimal implementation. Findings suggest that successful game-based learning requires well-structured activities, professional development for educators, and greater parental involvement. Addressing these challenges through targeted interventions could enhance its effectiveness in early childhood education. This study provides valuable insights into teachers’ and parents’ perceptions of play-based learning in cognitive development and underscores the need for collaborative efforts to maximize its potential. Future research should explore its long-term impacts and strategies for integrating it into diverse educational settings.

Published: February 2025

The goal of the research is to present the main peculiarities, with relate with the loads of flat wagon during maritime transport. A feature of the flat wagon is that its structure consists of two sections and special nodes are provided to fasten it to the ferry deck. A derived mathematical model expresses the lateral loading of the flat wagon under the conditions of a railway ferry roll. This derived model allows to to determine the acceleration and, accordingly, the loads due to the dynamic effects, which act to the flat wagon main load-bearing structure. These loads were considered in calculations of the strength of the main load-bearing structure of the solved wagon. The calculations lead to the results, that the strength of the main load-bearing structure of the considered flat wagon is maintained under the conditions of the considered type of oscillations. The performed research will contribute to improving the safety of maritime transport.
THE ANALYSIS OF VIBRATIONS IN A FLOOR PLATE WITH TWO SOURCES OF VIBRATION
Authors:   Kalashnikov Izhevsk State Technical University, Izhevsk, Russia, Pushkarev I.A.
Published: February 2025

This article presents a mathematical model of vibrations in a floor slab with two sources of vibration (rotors with unbalanced masses). The equations of the motion of a system of bodies are obtained using Lagrange equations of the second kind. An analytical solution to the system of differential equations is obtained under the assumption that the angular velocities of the vibration sources are constant. The vibrations of the floor slab consist of three components: a damped vibration, which has its own frequency, but is caused by the action of driving forces, and two forced vibrations. The results are presented using the example of vibrations of a 3 m long I-beam with several vibration sources with unbalanced masses. It was found that in some cases deflections may exceed permissible values. A structural model of systems with moving loads and vibration protection has been constructed, which visually represents the object under consideration, abstracting from its specific content. As practice shows, all kinds of vibration sources can be represented by a system with moving loads. The results of the study indicate the relevance of a more in-depth study of the influence of moving loads on the dynamics of building structures and the development of special vibration protection measures during the design, construction, and operation of buildings. Particular attention should be paid to simultaneous exposure to multiple vibration sources.

Abstract. The Russian cement industry is increasing the share of Portland cement production without mineral additives every year, reducing the consumption of granulated blast-furnace slag. This prompted the emergence of a relatively new product – ground granulated blast-furnace slag (GGBS), supplied directly to consumers of Portland cement, who use it as a component of cement in construction and engineering. The main manufacturer in Russia is Mechel-Materials LLC (Chelyabinsk). This enterprise conducts quality control at all stages of production: when receiving liquid blast-furnace slag, its granulation, and its fine grinding. The article provides information about the production technology of GGBS at this enterprise. Based on a literature review, it was established that GGBS gives cements and concretes several important advantages. However, studies of the influence of granulated slag on other important characteristics of cements and con-cretes are limited in the literature. Information on the influence of separately ground domestic granulated blast-furnace slag is even more limited. In this regard, a study was carried out on the influence of the ratio of GGBS and Portland cement on the construction and technical properties of the resulting cements and concretes. All tests were carried out in accordance with the current Russian standards. The test results show that the GGBS under study makes it possible to obtain cements and concretes with improved quality indicators: durability, cost, and environmentally sustainable development.

Published: February 2025

Hepatocellular carcinoma (HCC) is a cancer with poor prognosis, underscoring the urgent need for enhanced detection and management. This study aimed to investigate the role of Collectin Subfamily Member 10 (COLEC10) in HCC, which was revealed to be associated with various diseases. Bioinformatics tools, including GEO, cBioPortal, and TCGA, were used to identify differentially expressed genes. The prognostic significance of COLEC10 was assessed in two patient cohorts, and its functional impact on Hep3B and SMMC7721 cells was evaluated through CCK-8 and Transwell assays. The underlying mechanisms of COLEC10 in HCC progression were explored using flow cytometry and western blot. COLEC10 was downregulated in HCC and associated with poorer overall survival and disease progression. The potential interaction of COLEC10, CCBE1, and FCN3 was predicted. COLEC10, CCBE1, and FCN3 were identified as prognostic indicators for HCC. Overexpression of COLEC10 inhibited the proliferation, migration, and invasion of HCC cells. COLEC10 overexpression induced G0/G1 cell cycle arrest and suppressed epithelial–mesenchymal transition (EMT), COLEC10 regulated protein expression in the Hedgehog pathway and phosphorylation of key proteins in the PI3K-AKT pathway. COLEC10 is an independent prognostic factor of HCC. COLEC10 regulates EMT, Hedgehog, and PI3K-AKT pathways, providing new ideas for targeted therapy of HCC.

Würzburger Thesen zur Angewandten Sprachwissenschaft
Authors: Schulz Matthias , Schwebler Miriam
Published: February 2025

Applied Linguistics is Linguistics Plus: Compared to non-applied linguistic research, applied linguistics is characterized by a socially cooperative approach that focuses on linguistic and language-related problems and problem areas, a solution-oriented research design, networking with the outside world, and special application skills of the researchers.This is the conclusion of the conference “Applied and Applicable Linguistics – A Position Determination,” held in Würzburg in December 2023. The conference responded to an observation that can be made from a review of theoretical discussions of applied linguistics, but also from observing applied linguistic practice, for example at the conferences of the Gesellschaft für Angewandte Linguistik e. V.: Despite various attempts to define it, there are currently very different views of what applied linguistics is, what specific features characterise it and how it can be delineated from other areas or methodologies of linguistics. This normally causes no issue when, for example, negotiating different positions and a broad research discourse that promotes science – in practice, however, it makes it more difficult for applied linguistics to be perceived and recognised as a discipline in the research landscape and in society. Colleagues working in higher education as well as other sectors often point out the negative consequences for interdisciplinary cooperation, the acquisition of funding or the recruitment of early career researchers. The aim of the conference was therefore to discuss and clarify how applied linguistics is currently defined in German-speaking research practice and, at the same time, to outline a vision for the future ideally sparking further discussion. The focus was not on narrowing discourse, but rather on promoting discourse. The results of the conference are presented here in the form of theses, individually commented on by conference participants. They are intended as a starting point for further programmatic discussion.

Published: February 2025

O ferro é um micromineral essencial para a homeostase do organismo suíno, desempenhando inúmeras funções nas mais diversas reações metabólicas. A deficiência de ferro culmina em anemia ferropriva, implicando diretamente nos índices produtivos e no retorno econômico dos animais. O objetivo deste trabalho foi relatar a deficiência de ferro em leitões na fase de creche, com aproximadamente 60 dias de idade. Foram coletadas amostras de sangue de onze suínos que apresentavam quadro de diarreia e que não receberam suplementação de ferro, exceto o fornecido na ração. Os resultados obtidos demonstraram redução no número de hemácias, no volume globular e na produção de hemoglobina. Três amostras apresentaram anemia microcítica, com eritrócitos de tamanho reduzido, sugerindo uma possível deficiência de ferro. Conclui-se que a anemia ferropriva é uma condição que afeta predominantemente suínos, especialmente os jovens, resultando em impactos substanciais na cadeia produtiva suinícola e acarretando prejuízos econômicos significativos. Portanto, é crucial manter um manejo adequado de suplementação de ferro para prevenir problemas sanitários e promover a estabilidade econômica da indústria suinícola.
Natural supramolecular photosensitizer with in situ switchable photothermal/photodynamic effects as an imaging platform for precise and controlled cancer synergistic therapy
Authors: Fu Shiyao , Cheng Jianjun , Zhang Hua , Zhao Haitian , Wang Jiacheng , Wang Jing , Yang Xin
Published: February 2025

Treatment of cancer can be challenging, because of the disease’s intricate and varied nature. Consequently, developing nanomedicines with multimodal therapeutic capabilities for precise tumor therapy holds substantial promise in advancing cancer treatment. Herein, a nanoplatform strategy involving supramolecular photosensitizers (ETSCe6 NPs) and chelated metal ions (Au and Bi) was found to induce a shift in tumor microenvironment responsiveness from photothermal therapy to photodynamic therapy, thus facilitating tumor visualization for precise diagnosis and treatment. Self-assembly of supramolecular photosensitizers enhanced photothermal therapy through aggregation-caused quenching. Moreover, glutathione triggered disulfide bond cleavage, and consequently Ergosterol (ET) and Chlorin e6 release. Therefore, chemotherapy and photodynamic therapy achieved synergistic anticancer effects. Ce6 cavities were also used to chelate high valence Au and Bi metal ions for computed tomography. The ETSCe6@Au, Bi NPs demonstrated remarkable efficacy in vitro and in vivo, achieving complete tumor elimination after treatment. This integrated approach combining imaging, chemotherapy, photodynamic, and photothermal therapies has substantial promise for clinical applications, and may provide an innovative strategy for developing intelligent nanomedicines with promising prospects.

Published: February 2025

This study aims to investigate the deep historical connections between Minangkabau and Negeri Sembilan, two regions with rich cultural heritage in the archipelago. We explore the traces of this heritage to uncover the historical significance of Minangkabau in the formation and development of Negeri Sembilan's culture. The research method involved in-depth historical analyses as well as a careful literature review, which helped us understand the influence that Minangkabau culture has had on the social structure, customary system, values and traditions of the people of Negeri Sembilan. Our results show that this historical footprint reflects not only cultural adoption, but also the complex interaction between Minangkabau and Negeri Sembilan, which has shaped a rich and unique cultural identity in the history of the archipelago. Research findings reveal the deep-rooted nature of this cultural relationship, starting from the early arrival of Minangkabau people in Negeri Sembilan during the 15th and 16th centuries, to diplomatic relations with Raja Mahmud of Pagaruyung in 1773. The historical significance of Minangkabau in Negeri Sembilan culture has important relevance in understanding the cultural dynamics of the region.
Institutki: a «New Breed of People»
Authors: Varvara Ponomareva
Published: February 2025

The article, based on the principles of historicism, examines an episode which is key to
the history of the Russian women's school - the essence of the idea of Catherine II who
founded the first girls’ boarding school. The development of public education has been and is
one of the conditions for the socio-political modernization of the state. Empress Catherine II
and her associates, attaching great importance to education in the transformation of society,
justified the need to educate a person of a "new breed", a type of personality adequate to the
era, ready to respond to the challenges of the time. The enlighteners were convinced of the
possibility to correct morals by education. They intended to bring up worthy citizens in educational institutions based on the principles of the Enlightenment. In our historiography, this idea
is evaluated in different ways. In many works, the project of Catherine II is regarded as utopian since it is impossible to raise "ideal" people devoid of vices. But did the Empress, gifted
with common sense, plan to achieve such a goal? The meaning and methods of educating a
“new breed of people” were outlined by Catherine II’s collaborator I.I. Betskoy in several documents. These were program texts regulating the activities of new educational institutions:
orphanages, the cadet corps, as well as the girls’ boarding school, where future "new fathers
and new mothers" were to be trained. The accelerated pace of the country’s modernization
made it necessary to educate not only boys but also girls on a new basis. For this purpose,
the Smolny Institute was founded in 1764, where girls received upbringing and a systematic
education that was not inferior to that of men. According to the plan of Catherine II and her
associates, the newly educated "new fathers and mothers" were, in turn, to educate their
children in a new way, ensuring cultural continuity. The enlighteners were well aware of how
difficult their task was and understood that their work would not bear fruit soon. But, as the
author concludes, already the first girl graduates of the Smolny Institute showed positive results of the Russian enlighteners’ plan.
REAL EXCHANGE RATE UNDERVALUATION AND POVERTY REDUCTION IN SOUTH AFRICA: DOES THE NATURE OF PRODUCTIVITY GROWTH MATTER?
Authors:   Sol Plaatje University, South Africa, Mazorodze Brian Tavonga , Maduku Harris ,   Tshwane University of Technology, South Africa
Published: February 2025

While an undervalued exchange rate has gained prominence in the last three decades as a
correlate of economic growth and poverty alleviation, South Africa’s experience is less
encouraging as the depreciation of the Rand against the United States dollar barely coincided
with poverty reduction. Against this background, this paper sought to examine the impact of real
exchange rate undervaluation on poverty reduction in South Africa. It also investigated how the
nature of productivity growth influenced the impact of real exchange rate undervaluation on
poverty reduction. Using annual time series data observed between 1995 and 2020, evidence
from binary regressions and a Balassa-Samuelson adjusted undervaluation measure suggests
that an undervalued exchange rate could have potentially lifted people out of poverty had it been
accompanied by within-sector productivity growth of at least 2.5% annually. The South African
economy fell short of this threshold level between 1995 and 2020 as annual within-sector
productivity growth averaged 2.2%. Furthermore, evidence shows that South Africa went through
a structural change that shifted employment in the wrong direction. Low-skilled workers appear
to have moved from primary and secondary to tertiary sectors, a process that shrank overall
productivity growth.
Interprofessional education: Healthcare students' experiences
Authors: Van Wyk Heila , De Beer Marianne
Published: February 2025

Introduction:Inter-professional education has been identified as a strategy to overcome some challenges facing healthcare throughout the world. The aim of inter-professional programmes within institutions of higher education is to improve teamwork between healthcare professionals. Different professionals with a variety of skills are required to work effectively in a team for comprehensive and cost-effective healthcare. A number of research studies have investigated the outcomes of inter-professional education, but limited information is available to explain the mechanisms that led to these outcomes. This study could assist Inter-Professional Education (IPE) facilitators at institutions of higher education when developing and implementing IPE programmes.Method:Qualitative data of the final-year healthcare students' experiences of an inter-professional education programme were generated by means of a reflective essay. The essays were completed after participating in an inter-professional education programme and thematically analysed.Findings and conclusion:The findings of the study generated three main themes: the first theme was the outcomes of inter-professional education as experienced by the healthcare students, the second identified an environment in which teamwork was promoted, and the third identified certain attributes that team members needed for effective teamwork. The second and third themes were identified as mechanisms that lead to the outcomes described in theme one. It is recommended that facilitators of inter-professional education implement these mechanisms for optimal teamwork.KeywordsInter-professional education, healthcare student, qualitative, teamwork, mechanisms, outcomesÂ
Professionalism - A case for medical education to honour the societal contract
Authors: Nortjé Nico , De Jongh Jo-Celene
Published: February 2025

Background: This study explores the concept of professionalism from the vantage point of a cohort of students as well as professionally qualified and practising occupational therapists. With the changes health care delivery is experiencing nationally as well as internationally, there is an urgent need to identify students and qualified professionals' expectations of what influences the development thereof, as well as elicit perceptions of attributes which contribute to professionalism.Methods: The study is primarily a descriptive study with a specific focus on a mixed method of quantitative and qualitative research designs, using interpretative phenomenological analysis methodology. Data were gathered from 56 final-year and 55 professionally registered occupational therapists, who participated in a pen-and-paper questionnaire consisting of three sections.Results: The results of this study indicated a clear differentiation between the influence of both the formal and hidden curricula and that clinical competence, client-centred practice and professional standards contributed mostly to professional behaviour.Conclusion: This study brings to light the experiences of students and professional practitioners to what they expect would influence the professional conduct. The findings are open to theoretical generalizability and raise issues that may be used by academic staff in the preparation of students to become more professional, as well of future Continuous Professional Development training.Key words: Professionalism; Clinical competence; Client-Centred practice; Professional standards

This paper describes the effective integration and application of a hybrid analytical survey method in order to obtain a substantive profile and resource information about a patient/client population. Integrating the Vona du Toit Model of Creative Ability, the survey is used as a primary tool for planning intervention, evaluation and planning in occupational therapy practice. The process has been used extensively in action research in practices throughout South Africa and the United Kingdom and results have shown that it allows for a more targeted and efficient provision of intervention and treatment. This paper briefly describes the development of the Analytical Survey Method and details how the procedure is implemented using the example of its application in a United Kingdom healthcare facility. Its contemporary relevance is highlighted in the context of healthcare challenges and the need to demonstrate efficient and effective occupational therapy procision.occupational therapy provision.

Depoliticizing Transnational Cleavage‐Related Issues Through Social Media Advertising: The 2022 Danish Defense Referendum Campaign
Authors: Paulissen Toine , Jansen Lien , Van Hecke Steven
Published: February 2025

Denmark has an extensive but troubled experience when it comes to referendums related to the EU, with the Danes rejecting the pro-integration options in three votes up to 2022. As Denmark is the “home of issue voting,” these outcomes are symbolic of the transnational cleavage permeating its society, which has been argued to make the abolition of Denmark’s opt-outs impossible. Nevertheless, the full-scale Russian invasion of Ukraine in 2022 resulted in an apparent shift in the balance between the sides of this cleavage as Denmark subsequently voted overwhelmingly in favor of abolishing its EU defense opt-out. Scholarly work has argued that voters responded to efforts from the pro-abolition camp to depoliticize the issue of European integration, which raises the question of how the campaigning actors were able to achieve this. This contribution examines the role of social media advertising in this regard. Prior studies have focused primarily on social media discourse and its impact on voter behavior in referendum contexts, portraying it as a site for polarization and politicization, rather than depoliticization. We map the advertising expenditures of campaigning actors in the run-up to the referendum using data from the Meta Ad Library, and analyze their messaging using structured framing analysis to show how both sides in the campaign deal with the issue of European integration. Results show the pro-side being much more present than the contra-side, and offer empirical evidence for passive and active depoliticization strategies by the former vis-à-vis the transnational cleavage-related issue of European defense cooperation.

Industrial engineering is a dynamically developing field, integrating practices from several engineering disciplines. In this article, we analysed the development of science and research in industrial engineering by examining publication trends in indexed databases. Based on published studies, we identified key competencies required by industrial engineers to effectively manage corporate resources. Along with multidisciplinary knowledge, industrial engineers must be able to implement practical solutions considering environmental and safety aspects. The education is essential for future industrial engineers to have the opportunity to develop necessary skills. The article also explores the education of industrial engineers, and the development of the number of graduates in Slovakia. The results indicate that the content of industrial engineering education only partially meets current requirements. Additionally, our findings show a stable trend in industrial engineering publications in indexed databases, and after a decline, a slightly increasing trend in the number of industrial engineering graduates.

High-pressure die casts exhibit a certain amount of porosity, which can reduce their mechanical properties. One of the options for maintaining the porosity of casts at a low value is the correct gating system design. Presented contribution is based on the conclusions of the “Methodology assessment of the gating system numerical design of high-pressure die casting with regard to the material applicability” contribution. Individual numerical design methods gave different dimensions and cross-sections for the runners. Based on the assumption of a Reynolds number Re modification when altering the hydraulic cross-sections of the runners, it is possible to conclude that the nature of the melt flow in the runners is also shifting. The presented contribution aims to analytically determine the hydrodynamic conditions in the melt with different designs of the gating systems, determine the filling mode of the mold cavity and subsequently, using a simulation program, to determine the share of gas entrapment in the casts volume. At the end of the contribution, assumptions are deduced about the mechanism of gas entrapment in the casts volume.

Passive vibration isolation is a key factor in achieving precise results in milling processes and extending the service life of tools. An innovative approach involves using damping elements made from NiTi shape memory alloys. This approach is based on the alloys ability to convert large amounts of mechanical energy into thermal energy through the pseudo-elastic effect, with the pronounced transformation hysteresis of the material providing its damping potential. While previous experimental studies have offered valuable insights, analytical models are essential for accurately predicting the complex behavior of these materials. Therefore, the present work aims to develop an analytical model capable of predicting the characteristic properties of shape memory alloys under dynamic compressive loading. This not only offers a deeper understanding of the underlying physical mechanisms but also provides a solid foundation for the optimization and application of these alloys in real-world scenarios.
