Applications of 3D printing in physical geography education and urban visualization
Authors: Oswald Claire , Rinner Claus , Robinson Alexis
Published: February 2025

Through decreasing hardware costs and novel areas of application,  three-dimensional (3D) printing has become exceedingly popular in recent  years. Starting with a project focused on public education about urban  hydrology, we explored the use of 3D-printed landscape models in a  number of regional applications. We also experimented with the use of  3D-printed city models to engage users through urban visualization. Our  goal was to examine the role of GIS in processing geospatial data for 3D  printing and to explore novel applications in physical and urban  geography education and outreach. Following a brief review of related  literature, this article outlines data sources for digital elevation  models, boundary datasets, and building footprints with height  information and the processes used to transform these into 3D-printable  data files. We then describe applications focused on urban watersheds  and landforms in the area of Toronto, Canada, and illustrate city models  for neighbourhoods of Toronto. We found that the 3D models were  favourably received by diverse types of users, from hydrology experts to  environmental studies students to the general public. The  overwhelmingly positive feedback generated by this project suggests that  3D-printed landscape and city models are a worthwhile strategy for  improving physical and urban geography education and outreach. 
Immunotherapies to Nano-Immunotherapies: Advances in Immune Targeting in Bladder Cancer
Authors: Ramos Beatriz , Rogers Dakota
Published: February 2025

Bladder cancer is among most common malignancies worldwide, with significant morbidity and mortality. Conventional treatment strategies for bladder cancer include transurethral resection, radical cystectomy and chemotherapy. However, the complex immune landscape of bladder cancer involves innate and adaptive immune components that either promote or suppress tumor progression. Upregulation of checkpoint molecules like PD-L1 and recruitment of immunosuppressive cells, contribute to immune evasion and treatment resistance. Immune checkpoint inhibitors such as nivolumab, pembrolizumab, avelumab, and atezolizumab have shown promising results in clinical trials and have been approved for metastatic and high-risk bladder cancer. Additionally, Bacillus Calmette-Guérin (BCG) immunotherapy has long been in use as bladder cancer treatment. Furthermore, natural killer cell-based therapies and novel immune targets like TIGIT and CD155 are under investigation to enhance anti-tumor immunity. However, challenges such as toxic side-effects, variable response rates and the need for predictive biomarkers persists. Nanotechnology offers promising solutions to improve immunotherapy outcomes. Recent advances include the use of gold nanoparticles, TLR agonist-loaded nanoparticles, and exosome-based delivery systems to boost immune responses. Additionally, nanovaccine strategies incorporating tumor-associated antigens and immune adjuvants show potential for personalized cancer immunotherapy. Here, we discuss the immune landscape of bladder cancer, explore the emerging immunotherapies being used as bladder cancer treatment, and discuss the advantages of using nanoparticles as carriers of immunotherapies against bladder cancer. By optimizing combination strategies, identifying novel immunotherapeutic targets, and leveraging nanotechnology for precision medicine, future holds great promise in improving the efficacy of immunotherapies and alleviating bladder cancer burden.

Authors: Azennoud Abdessatar , Achraf Guaad  , Khawla Lamghari
Published: February 2025

This study explores the interactional practices and normative expectations of teachers and students in English as a Foreign Language (EFL) classroom, with a focus on turn-taking and conversational dynamics. Addressing a gap in understanding how institutional norms shape classroom interactions, the research employs Conversation Analysis (CA) as its methodological framework, emphasizing the systematic organization of talk-in-interaction. Data were collected from two recorded classroom sessions, including one conducted at the American Language Center in Rabat, Morocco, and another source from a publicly available YouTube video. The transcriptions, adhering to Jefferson’s (1988) system, were analyzed to uncover patterns of turn-taking, repair initiators, and backchanneling in teacher-student exchanges. The findings reveal that teachers use strategies such as other-initiated self-repair, scaffolding, and missing units to guide student contributions while managing conversational flow. Additionally, students demonstrated clear expectations for feedback, often signaled through transition relevance places. These practices underline the collaborative nature of EFL classroom interactions and the critical role of teachers in fostering language learning. The study highlights the pedagogical value of interactional competence and offers insights for improving teacher training and classroom engagement strategies.

Published: February 2025

The study aims to examine the impact of service quality, reputation, customer trust, price perception, satisfaction, switching costs, and commitment on the repurchase intentions of digital banking app users. The research targets digital banking app users who remain uncertain about trust, reputation, and satisfaction. The findings indicate that service quality, reputation, and customer trust significantly affect customer satisfaction, while price perception has no significant impact due to the minimal cost differences among digital banking services. Service quality, reputation, and trust indirectly influence repurchase intentions through satisfaction as a mediating variable. Switching costs were found to moderate the relationship between satisfaction and repurchase intentions, while commitment does not. This suggests that customer satisfaction directly affects repurchase intentions without the need for commitment as a moderating variable.

Ideological Representation in Turkish Cinema and Turkish Cinema During the AK Party Era
Authors: İnce Selami
Published: February 2025

Cinema has long been recognized by governments for its societal influence, and Turkey is no exception. During the early years of the Republic, while all fine arts flourished under state protection, cinema did not receive the same level of support. However, Turkish cinema evolved in line with the Republic's official ideology, emphasizing values such as modernization and secularism. As the government acknowledged cinema's power, it began directing the industry to align with state interests, promoting a "Western" worldview. Following the rise of the Justice and Development Party (AK Party) in 2002, Turkey underwent a shift toward conservatism, with religious values influencing cultural and social life. This article examines how the AK Party's conservative and religious agenda has shaped Turkish cinema, focusing on whether the 20 highest-grossing films of the AK Party era contributed to a new cultural hegemony and whether Turkish cinema has become more religiously oriented in this period.

Authors: Beltek M , Han O , Frolov A
Published: February 2025

Purpose. The purpose of research of the presented article is to identify the regularities of the explosion action in the massifs of different strength when modeling the process of rock fracture in the software environment ANSYS AUTODYN for given technological conditions.

The methods. The complex methodical approach was used, which consists in the analysis of previous results of scientific research on modeling the action of the explosion in ANSYS AUTODYN, comparative analysis of the obtained data on computer numerical simulation, graph-analytical establishment of the relationship between the volume of the explosive destruction funnel and the coefficient of structural weakening of the rock massif.

Findings. Computer modeling of explosive fracture of rock massif in ANSYS AUTODYN showed the reliability of the results obtained, which are confirmed by the research data of scientists and personal experience of the authors.It is established that the duration of active destructive pressure of explosion products in the rock under these conditions is about 0,35 ms. Further destruction of the rock massif is carried out under the action of accumulated loads in the rock and inertia of the rock mass movement up to 1,0...1,5 ms depending on the strength of the rock massif.

Images of rock mass fractures with different degrees of structural weakening were obtained, with the help of which volumetric figures of fracture funnels were created and their volumes were determined.It is established, that the volume of a funnel of destruction of granite which strength is accepted as strength in a laboratory sample, almost in 6 times less than volume of destruction of maximally structurally weakened granite rock massif.

Theoriginality. The graphical and analytical dependences of the destruction funnel volume on the structural weakening coefficient in rock massifs of different strength for the given modeling conditions have been established.

Practical implementation. The results of modeling the action of blast of cylindrical explosive charge in rock massif allow to optimize the parameters of drilling and blasting operations at mining enterprises for extraction of minerals, as well as during construction of underground structures for general and special purposes in massifs of different strength.
Peat deposits in Ukraine and in the world: current state, reserves, problems of geological and economic evaluation
Authors: Коlchev K
Published: February 2025

Purpose. Determination of the current state of peat reserves in Ukraine and in the world.

The methods. The work uses general scientific methods of research – empirical and theoretical (analysis, generalization, comparison, explanation, classification), as well as methods of statistical processing and display of analyzed information.

Findings. The data on the current state of peat reserves in the leading peat-producing countries of the world, Europe, and Ukraine are analyzed. 57% of the world's peat reserves are located in regions with boreal climates, but at the same time, tropical regions account for 21% of the reserves. This makes countries with large territories in the north (in particular, Canada and the United States) and in the tropics, in particular, Indonesia, the leaders. It was determined that there is no concept for the development of the peat industry in Ukraine. The problems of geological and economic assessment of peat deposits in Ukraine are the outdated data on the type of use, as well as environmental issues.

The originality.For the first time, the article identifies the urgent problem of reassessing geological and industrial peat reserves for existing enterprises and potential peat deposits in Ukraine. The analysis of the data shows that part of the reserves since the first geological exploration 40–60 years ago could have been converted to energy peat, which significantly increases the forecast value of reserves and requires taking this factor into account among other geological risks in the geological and economic assessment of these deposits. The environmental component of the problem of assessing geological risks for peat deposits in Ukraine has been further developed.

Practical implementation. The analysis of the current state of peat reserves allows us to clarify and inform the scientific community about the current state of peat reserves in Ukraine and the world, as the use of peat as a raw material in various industries is becoming relevant to address the problems of overcoming the consequences of the post-war economic crises and the development of innovative technologies.

Research methods.To predict the hydrodynamic regime and estimate filtration losses from the tailing dump, a numerical geofiltration model was developed in the Visual MODFLOW software package, which simulates a three-dimensional groundwater flow of constant density in a porous medium. The forecasting methodology involved a series of filtration and water-balance calculations, with a comparative assessment of changes in the hydrodynamic regime at the construction site based on alternative location options for the proposed tailing dump.

Results of the study. Using the method of mathematical modeling, a forecast of changes in the hydrodynamic regime of groundwater at the construction site was developed and an assessment of filtration losses from the designed tailing dump for its location options was performed. Based on the analysis of the balance components of the numerical model, the nature of groundwater supply and discharge was determined and the parameters of their hydrodynamic connection with surface water were established. Based on the modeling results, the choice of a hydrodynamically feasible tailing dump location was substantiated and measures to reduce filtration losses were identified.

Novelty. Based on the results of mathematical modeling, the paper establishes the dependence of the hydrodynamic regime of the designed tailing dump on the conditions of groundwater supply and discharge at the construction site, their connection with the regime of accumulated surface water within the existing hydraulic structures and the peculiarities of the geological and hydrogeological structure of the studied area in accordance with the options for the location of the hydraulic structure.

Practical significance of the results. The modeling results and estimates presented in this paper can be used to substantiate the projects for the construction of hydraulic structures in complex geological and hydrogeological conditions.

Purpose. To develop a structural and substructural state in thick-plate rolled products made of economically microalloyed steel that ensures the required high-performance properties for modern welded metal structures of critical importance.

The methods. To achieve this purpose, methods of metallographic analysis of material structures, chemical composition analysis, and evaluation of mechanical properties were utilized, including the assessment of brittleness and susceptibility to brittle fracture at reduced testing temperatures.

Results. An analysis of the production of low-carbon steels for modern special-purpose structures was conducted. Current steels in use do not fully meet the requirements for frameworks of critical-purpose structures. Domestic thick-plate steel demonstrates significant variability in strength and plastic properties across different directions of the material's volume. For instance, strength characteristics along the rolling direction can be 1.5–2.85 times higher than those in the Z-direction. This anisotropy arises due to pronounced ferrite-pearlite banding typical of thick hot-rolled plate structures. Such structural inhomogeneities, combined with the formation of axial segregation zones, increase the risk of delamination and reduce structural reliability. Moreover, the application of steels with pronounced ferrite-pearlite banding in construction is limited due to reduced impact toughness as plate thickness increases.

The originality. The obtained results further develop the application of steels with carbonitride strengthening, considering the embrittlement coefficient. In combination with solid-solution, dislocation, and subgrain strengthening, this approach ensures a high set of properties in modern welded metal structures of critical importance along the longitudinal, transverse, and Z-directions.

Practical implementation. The application of high-strength, high-toughness, low-carbon microalloyed steels opens the possibility for constructing taller buildings and large-span bridge structures.

Purpose. Conduct a study on the kinetics of austenite decomposition and determine the extent of influence of hot plastic deformation and interrupted cooling regimes on the structure formation of boron-containing steel.

Methods. The investigation of phase transformations was conducted using differential thermal analysis on samples of boron-containing steel, accompanied by studies of microstructure and hardness.

Results. The kinetics of transformations were studied, and a thermokinetic diagram of the decomposition of hot-deformed austenite in boron-containing steel was constructed, based on austenitization tempetatures ranging from 1050 to 11000С, followed by interrupted cooling and further cooling at a rate of 0,09 to 0,120 С/s, comparable to the cooling rate of the external coils of rolled bundles. It was established that the temperature-deformation regimes of rolling and the cooling conditions applied in real production technologies of underlayers (especially in bundled forms) are the cause of the appearance of a range of structural components in the treated steel. The heterogeneity of the structure causes an uneven distribution of properties along the length and cross-section of the underlayer, disrupts the thermodynamic conditions for the spheroidization of cementite, and significantly complicates the process of cold plastic deformation during upsetting.

Scientific novelty. The study investigated the impact of hot plastic deformation and interrupted cooling regimes on the kinetics of phase transformations in round bar rolling of boron-containing steel. The patterns of steel structure formation during cooling at various rates from the rolling temperature were established.

Practical significance. It has been discovered that for boron-containing steel, hot plastic deformation and interrupted cooling significantly influence the decomposition of austenite. Simultaneously, it has been demonstrated that their separate and individual effects on the kinetics of austenite decomposition differ substantially from the process of phase transformations. The obtained results can be utilized in the development of industrial technology for the production of thermally treated coiled rolled products made from boron-containing steel for cold upsetting with a relatively uniform spheroidized structure.
