Evaluation of surface tension of mold fluxes containing fluoride
Authors: Xu J.F. , Gu PW. , Su L.J. , Zhang J.Y.
Published: January 2025

Surface tension of mold flux is a key factor affecting optimum casting conditions. A thermodynamic model was developed to determine the surface tension of mold flux containing fluoride based on the ion and molecule coexistence theory of slag structure and Butler's equation. The relationship between composition and surface tension was investigated by this model. Results indicated that the calculated values showed good agreement with literature data, and the average error was 8.19%. The surface tension value of the CaO-Al2O3-based mold flux was larger than that of the CaO-SiO2-based mold flux. The surface tension in a multi-component system decreased with increasing contents of SiO2, CaF2, and Na2O, which are considered surface-active components. This trend was more significant in the CaO-Al2O3-based mold flux.
Modelling unsaturated dual-phase flow through crushed ores for heap leaching
Authors: Robertson S.W. , Petersen J.
Published: January 2025

Heap leaching is used extensively for the processing of low-grade copper, gold, and uranium ores. The hydrodynamics is often the most important factor that limits the rate of metal recovery. Over the past decades the author has performed physical and hydraulic testing of a large number of ore samples considered for heap leaching. The data were reviewed to investigate the effect of physical properties such as particle size distribution (PSD) and bulk density on the hydrology. The unsaturated flow through the bed is traditionally modelled with soil science models such as Brooks-Corey (BC) and Van Genuchten-Mualem (VGM), which relate the hydraulic conductivity to the degree of saturation, also known as the hydraulic conductivity function (HCF). However, most authors found a disconnect between the saturated hydraulic conductivity (Ks) and the rest of the HCF, which is explained as resulting from a transition from capillary-to gravity-controlled flow. However, the author found no such transition, and found the flow to be governed by capillary flow throughout. Traditional BC or VGM fits were found to be appropriate, however it was necessary to modify the model to include a point of inflection, above which the hydraulic conductivity remains constant while the moisture content keeps on increasing. It was proposed that this is the result of unconnected or poorly connected pores, which fill with solution but do not create additional flow channels. The point of discontinuity was also found to correspond with the air entry point, measured independently from the air conductivity curves. On average, the air entry point corresponds to the experiential rule that the void saturation should remain below 65% for aerated heaps.
Comparing the recovery of rare earth elements from ion-adsorption clay leach solutions using various precipitants
Authors: Chivavava J. , Petersen J. , Lewis A.E.
Published: January 2025

Rare earth elements (REEs) have special properties that prompted their extensive use in high-tech applications. The demand for REE has, therefore, increased over the past years, resulting in the supply risk of the materials. Extraction from non-conventional low-grade ores, like easy-to-mine ion-adsorption clays (IACs), by hydrometallurgical methods is being explored to supplement the supply of REEs. The extraction of REEs from low tenor IAC leach solutions requires enrichment using cost-effective methods such as precipitation. Therefore, the aim of this study was to understand the recovery of REEs from IAC leach solutions using various reagents for precipitation. In the first part of the study, recoveries of REEs from IAC leach solutions through direct precipitation using H2C2O4 and NH4HCO3, as well as antisolvent crystallization using C2H5OH, were predicted via thermodynamic modelling using OLI Stream Analyzer. Verification experiments were then conducted through the use of an agitated reactor. Simulation results showed that high yields of REEs were possible using each of the reagents, but large quantities of C2H5OH were required. Experimental results confirmed the high yields predicted from simulations. Precipitation with H2C2O4 was found to selectively recover REEs while rejecting Al. However, utilization of NH4HCO3 and C2H5OH resulted in the co-precipitation of Al. Furthermore, the yield of Y from antisolvent crystallization was significantly lower than the theoretical value. The product recovered from antisolvent crystallization consisted of well-faceted, large crystalline particles, which filtered faster than the fine, amorphous REE carbonates recovered using NH4HCO3. REE oxalates were crystalline, larger than the REE carbonates and, overall, showed the highest filtration rate.

Cilj istraživanja bio je ispitati kako ljudi percipiraju negativne posljedice klimatskih promjena u tri vremenska razdoblja (prije 25 godina, danas i za 25 godina) te ispitati postoji li povezanost između nekih socio-demografskih obilježja, religioznosti, političke orijentacije i percepcije rizika od klimatskih promjena.
Podatci su prikupljeni putem interneta od ožujka do lipnja 2023. godine, na kvotnom uzorku od 1.075
sudionika (51,9% žena), u dobi između 18 i 79 godina. Sudionici su izvijestili o svojim socio-demografskim obilježjima, o svojoj percepciji rizika od klimatskih promjena, kao i o svojoj religioznosti i političkoj orijentaciji. Deskriptivna analiza pokazala je da su sudionici u prosjeku procijenili kako je rizik od negativnih utjecaja od klimatskih promjena u sadašnjosti iznad vrijednosti koja je sredina skale procjene rizika.
Također, sudionici su u prosjeku procijenili i da je rizik od negativnih utjecaja od klimatskih promjena u
budućnosti iznad vrijednosti koja je sredina skale procjene rizika, ali je ta prosječna vrijednost bila viša od prosječne vrijednosti procjene sudionika o negativnim utjecajima klimatskih promjena u sadašnjosti. Rezultati multiple regresijske analize pokazali su da su spol i politička orijentacija značajni prediktori
percepcije rizika od klimatskih promjena, odnosno da su sudionici ženskog spola i lijeve političke orijentacije skloniji percipiranju kako postoje visoki rizici od klimatskih promjena. Ovo istraživanje produbljuje spoznaje o percepciji rizika od klimatskih promjena na uzorku hrvatskih sudionika te daje smjernice za buduća istraživanja percepcije rizika od klimatskih promjena.
“The city is ours” – Zagreb’s subcultures and space
Authors: Nuredinović Andrej Ivan , Vukušić Dino , Vukić Jana
Published: January 2025

This paper presents the results of research on the relationship between subcultural groups and spaces in Zagreb. Three ethnographic studies were conducted on three different groups – punks, skateboarders, and football supporters. By using qualitative methodological tools from an ethnographic approach (participant observation and interviews), the goal was to research different dimensions of the relationship between these groups and spaces within the urban environment. We were interested in how the subcultural identifications of subcultural groups influence the understanding of space. We approached the phenomenon of space primarily relationally, relying on the theory of Martina Löw, and then expanded on the understanding of
space for the subcultural actors themselves by using the subcultural theory of Erik Hannerz and Patrick Williams. Our results suggest the existence of common aspects of the use and experience of space among all three researched groups. At the same time, the relation to the mainstream through the prism of space is also evident, either on the convex or concave dimension of their subcultural identity.
Evaluating the importance of cultural heritage in a biosphere reserve: the case of Croats (Šokci) local community in the Mura-Drava-Danube biosphere reserve (Vojvodina, Serbia)

Biosphere reserves are protected areas recognized internationally as part of UNESCO’s Man and the Biosphere Programme. Their purpose is to test interdisciplinary approaches to managing interactions between ecological and social systems. Populated areas and communities of local inhabitants, with their customs, culture, and heritage, are integral parts of numerous biosphere reserves worldwide. Several initiatives and documents encourage the promotion of cultural diversity in biosphere reserves. Th e main objective of this study is to offer a fresh perspective on the significance of the cultural heritage of the Croats (Šokci) minority community located in the Serbian part of the cross-border Mura-Drava-Danube (MDD) Biosphere Reserve. Th e study makes use of the Analytic Hierarchy Process (AHP) technique to achieve this goal. Seven experts,
who are considered as being connoisseurs of the cultural heritage of the Croats (Šokci) and the Mura-Drava-Danube Biosphere Reserve, were interviewed as part of this study. Th e results indicate that factors such as sense of belonging and pride of the local community are crucial for the preservation and management of cultural values in the Biosphere Reserve. Th ese aspects can also play a practical role in tourism development, which is recognized as one of the most significant activities in biosphere reserves across the globe.

The block represents one of the main structuring elements of urban form, serving as a point of connection between public and private spaces. In various approaches and morphological concepts, the block is identified as a fundamental component and can be analysed at different scales, from the city to the building, considering its architectural typology. This article aims to investigate the morphological patterns of blocks in the city of Patos, Paraíba, Brazil. The research problem is centred on the discussion of the types of blocks that have been built in the process of evolution and occupation of urban space. The methodology consists of modelling georeferenced data on morphological elements and calculating the length and connectivity of block segments, area, compactness and occupancy rate of blocks. The findings indicate a morphological pattern of the blocks associated with the centre-periphery dichotomy: the central area of the city has a higher building density, smaller and more compact blocks, with a greater human scale and public-private interface, while the more peripheral zones have smaller, less compact and dispersed blocks, generating more sprawling areas with less direct relationship between public and private spaces. These results help us to better understand how the process of urban evolution has moulded the city's blocks, associating them with different socio-spatial phenomena.

The fate of idle structures, which have had their original functions interrupted due to social, historical, or economic-productive changes, presents an opportunity to debate the architectural heritage value in cities. It is through the distorted return, stemming from the resignifications of these structures, that new paths can be opened. The dimension of property as something that is inherent and intrinsic is broken. Idle structures existing in urban areas cease to have their own characteristics, opening up to new possibilities and being available for inventive rehabilitations. In this process, an aesthetic based on addition through architectural couplings is highlighted, suggesting another ethic in the way of building sustainable landscapes and urban dynamics. The idea of reactivating obsolete and abandoned structures, ruined and not simply erased, becomes, around the concept of assemblage, the main vector of analysis and problematization of this article. We will start from the analysis of two works located in Paris for a critical problematization around the defense of the maintenance and reactivation of abandoned and ruined structures, namely the Cité de la Mode et du Design and the Entrepôt Macdonald.

Published: January 2025

In the last decades, the climate has been the subject of studies in various regions of the world, especially urban climate. The increase in built-up areas combined with the decrease in vegetation, increasingly intense, contribute to the formation of a climate with distinct characteristics compared to rural areas. Therefore, the general objective of this study was to analyze, based on remote sensing data, the relationship between land use and land cover and its influence on surface temperature and NDVI of the city of Manacapuru, located in the metropolitan region of Manaus. The data were analyzed through geographic information systems, using the QGIS 3.16 Hannover software, land use and land cover data from the Mapbiomas collection 6 of 2020, and remote sensing images from the Landsat 8 satellite bands 10 TIRS, for surface temperature, and bands 4 and 5 OLI, for NDVI. The result was a predominance of urbanized areas, with a minimum surface temperature of 24.6°C, an average of 28.8°C, and a maximum of 33.1°C, with a range of 8.5°C. The NDVI ranged from -0.05 to 0.53, respectively indicating areas with absence, little, moderate, and dense vegetation. Finally, tree planting plays an important role in mitigating city temperatures, as it intercepts much of the radiation emitted by the sun, preventing heat from reaching the surface, providing thermal comfort, and on the other hand, the removal of vegetation and the intensification of urban areas increase the configuration of heat islands.

Making cities and human settlements inclusive, safe, resilient, and sustainable is one of the objectives established in the 2030 Agenda by the UN (United Nations) and a commitment made by all member countries, including Brazil (UNITED NATIONS, 2015). In this context, urban planning policies and actions addressing environmental issues are fundamental to achieving the established goals. This study aims to investigate which urban planning policies and actions contribute to environmental sustainability in large cities. The specific objectives are to determine the main challenges in incorporating sustainable practices into urban planning and to relate the potential benefits of implementing green infrastructure in urban areas. This is a literature review that addresses concepts, characteristics, classifications, and definitions according to relevant standards on the subject. Among the results, it was possible to define the concept of Sustainable Urban Planning and identify the main strategies for Urban Sustainability. It was concluded that to achieve sustainability in urban planning, it is essential to adopt an integrated and participatory approach, ensuring that policies benefit all segments of the population and contribute to the sustainable development of cities.
RESOURCE ASPECTS OF SPORTS TOURISM DEVELOPMENT IN UKRAINE IN THE POST-WAR PERIOD
Authors:   Khortytsia National Educational and Rehabilitation Academy, KOLLEHAIEV Mykhailo
Published: January 2025

The article investigates the problems of the development of sports hiking tourism in Ukraine associated with the annexation of Crimea in 2014 and the full-scale invasion of the Russian Federation in 2022. It was established that as a result of the aggressive policy of the Russian Federation, significant territories were temporarily lost or became inaccessible (up to 40% in general), which have important resources for the development of hiking tourism in Ukraine. At the same time, about 174,000 square kilometers are potentially contaminated with explosives, which is 30% of the country's territory. The prospects for replacing the resources of temporarily inaccessible territories for hiking tourism with other regions of Ukraine in the post-war period have been researched. Studies of the consequences of the annexation of Crimea and the prospects for replacing temporarily lost camping resources at the expense of other regions of continental Ukraine established the following: continental Ukraine has the necessary replacement resources practically for all types of sports hiking tourism; the redistribution of tourist flows will increase the popularity among hikers of such previously underestimated areas of Central and Western Ukraine as Podilia, Polissia, and Bukovina. Research into the effects of the full-scale invasion of the Russian Federation in 2022 on the development of sports tourism have shown that tourism activities and hiking are not prohibited in Ukraine, and local restrictions and bans are determined by resolutions of the Military and local administrations. In general, Western and certain regions of Central Ukraine remained available for hiking. At the same time, most of the hiking activity in 2022–2023 was concentrated in the Carpathians, except for the border areas. A comparative analysis of sports and tourism potentials has been carried out: throughout Ukraine; annexed Crimea; territories contaminated with explosive objects, and remaining regions accessible for hiking. It is established that after 2014 the sports and tourism potential of the Crimean Mountains was gradually replaced by the resources of the Carpathians, Podilia, Polissia, and Bukovina, as well as the trekking routes of Southwestern Turkey. It is established that the polluted regions have a resource value of local importance for hikes of low complexity. At the same time, the regions accessible for hiking have a sports and tourism potential comparable to the potential of integral Ukraine, and therefore, in the next decade after the Victory in the war, they will be able to successfully replace the potential of mined and contaminated territories.
Acts of creativity in oral and written language teaching in secondary school: a handbook review
Authors:   Taras Shevchenko National University of Kyiv, Kyiv, Ukraine, Liubashenko Olesia , Drahinda Olha ,   Taras Shevchenko National University of Kyiv, Kyiv, Ukraine
Published: January 2025

This review of the handbook by Olesia Liubashenko & Olha Drahinda, "Enhancing Students' Oral and Written Creative Language," is intended for English-speaking readers interested in the achievements in the development of creative oral and written language skills among secondary school students in Ukraine. It is aimed at university students who have been trained to teach the Ukrainian language to secondary school students, with a particular focus on fostering creativity in both oral and written expression.

The authors' training is based on the investment theory of creativity. According to this theory, creativity is defined as generating ideas that reflect the success of human capital investment. This implies that even a common notion, a well-established truth, or information that has been repeatedly conveyed retains the potential for creative transformation. A mere alteration of perspective, a revision of analytical techniques, or an examination of what may initially appear to be implausible is sufficient to trigger creativity.

Accordingly, the book presents a teaching strategy that integrates the creation of oral and written texts with the acquisition of the Ukrainian language, its genres and the stylistic standards outlined in the school curriculum. It includes Ukrainian translations of English fiction, non-fiction, and academic texts, providing resources that foster such an important type of thinking as lateral thinking. The authors offer a set of classroom-ready tools to equip pre-service teachers with the skills to design engaging lessons, unleash their own creativity, and inspire their students to engage in creative pursuits within the context of a modern, multicultural, and multilingual educational environment.

It is proposed that in the existing disciplines related to software development to increase attention to the quality of the created program code for the possibility of its free use. The skill of creating high-quality code is most easily developed when working on a project in a team.
Culture as an Order (among the Plurality) of Values
Authors: Rozwadowski Łukasz
Published: January 2025

The article presents a concept according to which the distinctiveness of a given culture is determined by the order of values arranged in it in a specific way. First of all, the article considers how to emphasize the functional and dynamic aspect of the arranging of values. For this purpose, the notion of performativity has been included with the concept. Second, the article proposes to distinguish three ways of establishing relationships between values: hierarchization, intertwining, and distancing. Third, the article distinguishes the basic axiological assumptions on which the idea of culture as the ordering of values is based. In this regard, exceptionally crucial was the question whether this concept entails a position of axiological pluralism.

Historical relativity of moral values and historical relativism
Authors: Płoszczyniec Antoni
Published: January 2025

The aim of this text is a critical reflection on historical-axiological relativism. According to the thesis of the work, the (possible) relativity of moral values does not entail relativism. In other words: one can affirm the relativity (in some aspects) of moral values or morality itself, while rejecting the relativistic view of moral values. The article applies analytical methods. First of all, the above-mentioned methods serve to highlight the constitutive properties of moral values (in particular other-planning), and later to reconstruct the structure of relativistic concepts. The collected information is used for criticism, which proceeds in two ways: it criticizes the relativistic content of historical relativism and criticizes the thesis that history has the power to make values relative. At the end of the text, an original argument was formulated, according to which history itself cannot make moral values relative, which makes historical relativism a non-independent position.
Pluralism and Relativism in Ethics Starting from W. K. Frankena
Authors: Allegri Francesco
Published: January 2025

This article connects pluralism and relativism in ethics through the path of a classic scholar of 20th century moral philosophy: W. K. Frankena. In normative ethics Frankena defends a pluralist perspective, because in his theory of obligation there is a plurality of basic moral principles (exactly two) that may conflict with one another and there is no strict order of priority for resolving conflicts between them. His attitude towards ethical relativism is, however, negative, because in his view all three version of relativism in the moral sphere (descriptive, metaethical, and normative) are questionable. The author explains the reasons for the plausibility of a pluralist model in normative ethics, but he shows more openness to relativism than Frankena. In particular, the author defends a moderate version of descriptive and metaethical relativism, allowing that conflicting moral evaluations of certain issues may be equally justified. Such a form of relativism, far from constituting a “bogeyman”, simply expresses the idea that the correct use of reason does not necessarily lead to a single outcome, but can yield a plurality of results (without thereby allowing every result).
On the Legitimacy of Eristic in the Context of Rhetoric
Authors: Rojek Krzysztof
Published: January 2025

This paper is an attempt at a contemporary revision of eristics from the perspective of an allegation of being an immoral art of excuses that is only pretending to be rhetoric, a noble art of striving for the truth which is commonly (since ancient times) formulated against the eristics. To achieve this goal, it is necessary to evaluate the connection between rhetoric and eristics, especially in terms of similarities. The Aristotelian characteristic of eristics has already separated the two, indicating the dishonesty of those who use eristics. Artur Schopenhauer, in turn, diagnoses the term ‘disagreement’ by pointing out the innate tendency among people to win regardless of the means. Krzysztof Szymanek, on the other hand, strives to justify and, in a way, ‘cleanse’ the eristics from a part of the pejorative labels, showing mainly its technical dimension and partly combining it with rhetoric in terms of the impact that it has on the auditorium. The educational function of eristics, although it does not constitute its main purpose, allows for an evaluation of the eristics as a component of the art of arguments rather than just a collection of techniques unworthy of a respected speaker.

Authors: Busnetti Ida , Tambunan Tulus
Published: January 2025

The availability of information and communication technology (ICT) has assisted companies to effectively produce and market their products and services in the global market. However, the majority of micro and small enterprises (MSEs) in Indonesia have not adopted such technology or e-commerce to support their business activities. Based on province data (cross-section data), this study aims to examine the adoption of e-commerce by MSEs in different provinces in Indonesia. It addresses two research questions. First, how many MSEs have adopted such technology? Second, what factors influence e-commerce adoption by MSEs? The study used multiple regression to estimate empirically the impact of selected factors as independent variables on the number of MSEs that use e-commerce. It shows at least three important facts: (i) the degree of e-commerce adoption by MSEs in Indonesia is still very low; (ii) there is a positive relationship between market size in a province and the number of MSEs in the province adopting e-commerce; and (iii) in a region where all residents or households have a computer or access to the Internet, it is not always that all business actors, especially MSEs, in that region adopt e-commerce.

Traditional village economies with tight and cohesive social networks in which the quantity and quality of information on people's characteristics are relatively high can be a favorable environment to convey information about the issue of Vietnamese immigrant workers internationally. This research examines social networks, especially kinship ties, and studies the effects of such networks on the overseas migration of Vietnamese youth in their migration decision-making process to Northeast Asia. Based on the results of surveys and in-depth interviews, the study shows that Vietnamese youth migrants utilize social networks to facilitate their migration efforts in Do Thanh commune, Yen Thanh district, Nghe An province. Migration networks not only relay information from places of departure and arrival but also provide practical support and assurance for the migration process of new people. This contributes to the creation of a “chain migration” system. The article aims to provide insights into how Vietnamese workers choose to migrate and emphasizes the impact of their migration choices.
Shifting Perceptions in School Choice: The Impact of Presenting High-quality Schools first in Recifes Centralized Admission System
Authors: Elacqua Gregory , Kutscher Macarena , Rodrigues Mateus
Published: January 2025

The potential efficacy of centralized school choice systems in reducing inequalities in access to high-quality schools may be hindered by informational frictions. In this paper, we experimentally evaluate a low-cost information intervention in the centralized school admission system (Matrícula Digital) of Recife, Brazil. The intervention modified how school vacancies were initially displayed on the application platform: the treatment group first saw schools listed by quality; the control group first saw them ordered by proximity to the student's home, i.e., the default order. We focus on students applying to first grade, the level with the highest participation rate since all pupils entering the municipal school system must go through this process. We find no overall effect of the school ordering change on the quality of the schools selected. However, when we restrict our analysis to students who live near at least one of the top three schools on the list, we observe a significant positive effect. This effect weakens as distance from home increases. Our findings indicate the importance of school quality in relation to proximity to the students residence. This conclusion is supported by a parental survey conducted after admissions, in which 80% of respondents indicated that proximity was the most important factor in their school choice. These results have considerable implications for the design of effective educational information interventions.

System Theory-Based Approach for Hazard Analysis and Control in a Metalliferous Mine
Authors: Singh S. , Sinha A. K.
Published: January 2025

System Theoretic Process Analysis (STPA), introduced by Leveson, represents a modern hazard analysis technique capable of capturing diverse causal scenarios, including non-failure scenarios. This paper presents a case study illustrating the application of STPA for hazard analysis and control in a large metalliferous mine with both opencast and underground operations. To support this initiative, an Information Technology (IT)--enabled system called the AK Safe app was developed based on an integrated approach and system theory. This app facilitated the collection of over 600 hazard control feedback entries from the mine. These entries were subsequently analysed using system dynamic models.
Major Findings: The study's findings are crucial in identifying inadequate or missing control measures by providing a structured method to examine system hazard control actions and feedback pathways. This analysis enables timely mitigation actions to address identified hazards effectively.

Published: January 2025

The study explores the effects of different meshing techniques on the accuracy and efficiency of heat transfer and fluid dynamics simulations in a finned heat exchanger. A 3D-CAD model, developed in Autodesk Fusion, analysed aluminium fins subjected to a heat flux of 5903 W/m² under flow conditions with Reynolds numbers from 8490 to 23300. Four mesh types Tetrahedral, Polyhedral, Hexacore and Poly-Hexacore were compared. Mesh independence analysis showed that Hexacore meshes, especially Mesh Set-F (4,568,602 elements), delivered high accuracy in predicting Nusselt numbers and pressure drops, making them suitable for detailed simulations. Polyhedral meshes, particularly Mesh Set-E (498,044 elements), exhibited the best computational efficiency, ideal for resource-conscious analyses. The study underscores the trade-offs between accuracy and computational cost. Hexacore meshes are recommended for precise evaluations, while Polyhedral meshes are better suited for preliminary designs or time-sensitive applications. However, Hexacore meshes require higher computational resources, limiting their practicality for large-scale or real-time simulations.
Major Findings: The findings are valuable for industries such as Heating Ventilation Air Conditioning (HVAC), automotive and electronics cooling, where heat exchanger performance predictions are crucial. By tailoring mesh configurations to specific project needs, engineers can optimise simulation accuracy and computational efficiency, enhancing design workflows and outcomes. The study provides a framework for balancing accuracy and cost, offering insights into mesh selection for effective thermal and fluid performance evaluations.
A Review on Additively Manufactured AlSi10Mg Alloy: Mechanical, Tribological, and Microstructure Properties
Authors: Gadlegaonkar Nagareddy , Bansod Premendra J. , Lakshmikanthan Avinash , Bhole Krishnakant
Published: January 2025

Additive Manufacturing (AM) has rapidly evolved as a transformative technology, enabling the production of complex, highperformance materials that exhibit superior mechanical and tribological properties. Among the materials benefiting from this advancement is AlSi10Mg, an aluminum-silicon-magnesium alloy. AlSi10Mg has gained notable attention in industries like aerospace and automotive due to its excellent strength-to-weight ratio, high thermal conductivity, and robust wear resistance. These properties make it particularly suitable for lightweight, high-stress applications. This review consolidates state-of-the-art research on AlSi10Mg, specifically focusing on components produced through Selective Laser Melting (SLM), a prominent AM technique. SLM enables precise control over the materials microstructure and properties by melting and fusing powdered material layer-by-layer using a high-energy laser. The review delves into the influence of various SLM processing parameters, play a crucial role in influencing the alloy’s density, porosity, and internal stress, ultimately affecting its mechanical performance. Additionally, the review examines post-processing treatments enhancing AlSi10Mg’s strength, ductility, and fatigue resistance. Furthermore, the impact of these treatments on the alloy's microstructure, particularly the distribution and morphology of silicon phases within the aluminum matrix, is critically discussed, as they influence wear resistance and hardness.
Major Findings: The major findings in this work are the potential of AM-produced AlSi10Mg as a high-performance material for industrial applications, highlighting current challenges and future research directions aimed at optimizing processing.
Collaborate or Perish: The New Mantra for MOGI Companies in Transition. Survive and Prosper Together, or Fail Alone. Part-1
Authors: Bhattacharya Jayanta
Published: January 2025

In the interconnected world, collaboration is the game changer. Agencies and firms, citizens and groups who can collaborate, will thrive in the networked world; those who cannot are doomed to perish. There is considerable evidence to suggest that collaboration is a necessary condition to drive innovation, particularly transformational innovation. The mining industry can harness the potential of collaboration to achieve more than just productivity gains, by focusing on sector-wide efficiency gains and moving over to the newer technology domains by handholding, which will benefit all the participants rather than give anyone a competitive advantage. This article explains the recent examples of collaboration where companies are looking for complementarities to harness growth and prepare for the future.

El cáncer infantil es una enfermedad que puede ser vista desde diferentes áreas del conocimiento. Los principales afectados son los sujetos que la padecen, por lo cual, se considera que su experiencia es de suma importancia; sin embargo, actualmente existe poca literatura acerca de este tema en Colombia. Por esta razón, se desarrolló este estudio con el objetivo de interpretar y comprender la experiencia del cáncer infantil por medio de la fenomenología hermenéutica. Entre septiembre y noviembre de 2022 se realizaron 18 entrevistas semiestructuradas a población pediátrica oncológica en una fundación en Bogotá. En estas se indagó sobre la experiencia vivida con el impacto del diagnóstico, las redes de apoyo, los cambios en hábitos y rutinas, la religión/espiritualidad, las creencias sobre la enfermedad, entre otros aspectos. Como resultado, la población infantil sufre el tratamiento no solo por el dolor físico secundario, sino por la pérdida de la identidad y la alteración en la relación con la familia y los amigos; no obstante, ellos mismos han desarrollado mecanismos de afrontamiento y aprendizaje ante la enfermedad. En conclusión, el cáncer es un proceso que cambia la percepción de la vida de la población pediátrica oncológica que lo padece, y la fenomenología es una herramienta que permite entender de mejor manera la vivencia del cáncer desde la perspectiva personal, esto contribuye a tener un trato más humanizado e integral de la enfermedad.

In any design project, the technology must be correct and in any art project, the work must be captivating. While this is essential for a successful outcome, the author believes that it should be simply considered as the result, which it is assumed will be delivered. This project is the path to this outcome and presents a myriad of other challenges. In this paper, the author looks at two projects, First, the £18 million project to design significant improvements to Belfast’s digital infrastructure; and second, the preparation of a 12-venue series of exhibitions featuring paintings drawn from the heritage of the Huguenots in Ireland. This paper aims to chart the way through the delivery of these two projects, with an approach that focuses on highlighting the core challenges of understanding vision, environment, and culture, describing how these were handled. The unavoidable conclusion is that the activities and skills applied in the two sectors reveal more similarities than differences. In pulling back the curtain, he contradicts the romantic myths of designer geeks and freewheeling artists. This paper will contribute to the world of art and design practically by filling in the existing gaps regarding how to handle large projects.
