Islamic Environmental Stewardship: A Sociological Approach to Hadith and Legal Frameworks for Ecological Responsibility
Authors: Salman Abdul Matin bin , Asmanto Eko
Published: December 2024

This research analyzes the approach of Islamic law to environmental management through the study of Hadith from a sociological approach. The environment is an essential issue in the modern world, with various challenges related to nature conservation. Islamic law, mainly through the Hadith, provides moral and legal guidance on human responsibility towards the environment. This study explores how the Hadiths provide the basis for balanced and sustainable environmental management and how these principles can be analyzed using a legal sociology approach: the interaction between law and society. Using a qualitative method that combines the study of Hadith texts with sociological analysis, the study found a unity between Islamic law and social norms that promote environmental sustainability. Hadith underscores the importance of individual and collective responsibility in maintaining the balance of nature. At the same time, legal sociology highlights the role of community and social structure in implementing environmental rules. The results of this research aim to gain a deeper insight into the relevance of Islamic teachings in dealing with global environmental issues and to become the basis for developing a more holistic and integrated policy to preserve nature.
Critical Consciousness, Te Tiriti o Waitangi and Public Health Education
Authors: Severinsen Christina , Reweti Angelique
Published: December 2024

Aotearoa New Zealand is experiencing a significant shift in political discourse surrounding Te Tiriti o Waitangi. The current government, under the guise of ending ‘race-based’ policies and reducing bureaucracy, is proposing changes that threaten to erode the rights and protections of tāngata whenua [Indigenous people of the land]. While the coalition government asserts its commitment to improving outcomes for all New Zealanders, the changes represent a direct assault on Māori that will disproportionately and negatively impact Māori communities. In this political climate, the role of education becomes even more critical. As educators in public health, our commitment to uphold the provisions and principles of Te Tiriti o Waitangi and to foster understanding is unwavering and more pressing than ever. In this opinion piece, we argue that embedding Te Tiriti o Waitangi meaningfully throughout our curriculum is not just beneficial but essential.

The future of the audience in post-television. The case of the italian talk-show Propaganda Live!
Authors: MAGNONI Corrado
Published: December 2024

We live in a very difficult and confusing time of using various media. To undergo this constant process of change is above all the television that seeks a way to reposition itself and adapt to the new type of audience. Our goal is to bring order and shape the future of traditional media. According to Jenkins[1] we will try to better define what is meant by cross-media, trans-media and omnimediality. Many authors give different definitions, but we are sure that we can arrive at a new means of spreading news that is more valid than the previous ones from a qualitative point of view. The objectives of the research is to contribute to forming a new type of text that is both multimedia and interactive. A story inserted in a context that demonstrates how unidirectional communication is no longer possible and where the world of media is increasingly called upon to greater involvement of the end user. The aim is to compete with the latter, which is already partly happening, in an orderly process of cross-media use. The idea that the interaction between television and social media can improve the audience for both is based on a profound change in the way people consume content. Today, watching TV is no longer a passive and solitary experience as it used to be.

National Recovery and Resilience Plan (NRRP) in the Romanian Online News Media. Media Representations and Political Discourse of the Key Actors
Authors: TROFIN Constantin
Published: December 2024

The Romanian media coverage of the NRRP builds on the political discourse of the public actors who mainly used the NRRP debate either to gain visibility, or to campaign. Emotions, conflict and negativity news values are dominant, and the analysis and contextualization usually lack from the news stories. The present study is a content based approach, which aims to identify who are the most prominent actors involved in the debate about the Romanian National Recovery and Resilience Plan, how these public figures are inter-connected in the media discourse and which are the main features of their discourse, and what topics associated to the six pillars of the Recovery and Resilience Facility are mentioned most frequently in the public discourse of the key public actors.

Published: December 2024

This research uses both quantitative and qualitative research methodologies to examine the complex factors affecting community resilience in various settings. In this case, the research explores how social cohesion, governance effectiveness, adaptability, community involvement, and the specified difficulties influence resilience results by using the five pillars of resilience as variables. Descriptive and inferential statistics are used to test hypotheses on the relationships between social cohesion, governance effectiveness, adaptive capacity, and community resilience variables. Qualitative data provides further insights into the quantitative results by providing broader views and experiences of the community. The study shows how social capital is important in increasing community capacity, stressing the importance of social relations and trust in developing community solutions to disasters. Another major factor that stands out is the governance factor that ensures that decisions are made, and actions taken in line with the community’s best interest in improving its ability to prepare for and respond to disasters. Adaptive capacity is seen as a key component of resilience and this paper emphasizes the importance of communities to come up with measures that can be adjusted to the changing circumstances. In summary, this study enriches theoretical understanding and offers practical applications of the processes that can enhance community resilience based on the principles of social inclusion, sound governance, and context-specific solutions.

Efeitos da inobservância da cadeia de custódia sob à ótica do Superior Tribunal de Justiça (STJ)
Authors: Silva Arthur Saatkamp da , Puhl Eduardo
Published: December 2024

A preservação da cadeia de custódia é fundamental para o bom funcionamento do processo penal, visando assegurar a integridade e autenticidade das provas apresentadas, desde a coleta à apresentação em juízo. O presente artigo objetiva analisar como o Superior Tribunal de Justiça (STJ) define as consequências da quebra dessa cadeia diante da omissão legislativa acerca dos efeitos causados pela inobservância desse procedimento. A Lei n. 13.964/19 introduziu a cadeia de custódia no ordenamento jurídico, que se trata de procedimentos que garantem a rastreabilidade das provas. Quando esses procedimentos não são observados, a validade das provas pode ser comprometida. Analisando a jurisprudência do STJ, infere-se que a Corte avalia cada caso individualmente para determinar a nulidade ou validade das provas com base na observância da cadeia de custódia. Recentemente, o STJ considerou provas inadmissíveis caso a documentação da cadeia de custódia for inadequada, porém, reconheceu que a inobservância, por si só, não invalida automaticamente uma condenação se houver outras provas suficientes do crime. Conclui-se, então, que a cadeia de custódia é essencial para um sistema de justiça criminal justo e eficiente, mas ainda são necessárias medidas para preencher lacunas legislativas sobre o tema, visando o bom funcionamento do processo penal.
Micrographic image of air pollutants in Poland
Authors: Szwed Mirosław , Pasieka Dariusz
Published: December 2024

The subject of studies was one-year-old needles of Scots pine (Pinus sylvestris L.), collected from various characteristic landscape zones of Poland, reflecting different conditions of air pollutant emission and deposition (Integrated Monitoring of the Natural Environment base stations, industrial centers, and large cities). Analyses were carried out using a Quanta 250 FEI scanning electron microscope equipped with an EDAX Genesis X-ray spectroscopy microanalyzer. The needle surfaces were examined to identify natural structures (e.g., stomata, pollen, fungi) and anthropogenic structures (e.g. particulates with heavy metals) under conditions of diversified anthropopressure. In samples from areas with no significant local pollution sources (Wigry, Borecka Forest, Parsęta, Tuchola Forest), particles of mineral origin (resulting from rock weathering) containing Si, Al, Ca were identified. Needles collected in Roztocze, Łysogóry, Kampinos and Karkonosze, contained round technogenic particles (spherules) containing Fe, Al and Si, which had traveled significant distances. In Katowice, Poznań and Kraków, particles deposited on the bioindicators’ surfaces were composed of Ca, Si, Al, Fe, Cu, and other heavy metals. Micrographs obtained from the analysis were used to develop a model for identifying air pollutants using artificial intelligence.
Assessment of changes in environmental pollution by road noise using a scalar measure
Authors: Bąkowski Andrzej , Batko Wojciech , Radziszewski Leszek
Published: December 2024

The article addresses the issue of assessing the impact of road rebuilding on traffic noise pollution. To assess noise hazards, parameters expressed on the decibel scale were used, and a new measure was proposed - a scalar reference that compares the sound level value to the recommended threshold. This measure is based on Weber Fechner's law, which relates to human perception of changes in sound levels. It was derived through the decibel algebra applied to measurement results and is called the “coefficient of exceedance of the recommended sound level”. Its usefulness was verified by analyzing the results of measurements of traffic and noise parameters before and two years after the reconstruction of a section of the national road in Kielce. An assessment was made of traffic volume, vehicle speed, and road vehicle noise. The analysis evaluated the absolute values, variability and uncertainty of results obtained for the entire year, Fridays and Sundays. Significant differences in traffic parameter values were observed between the lanes entering and leaving the city on weekdays and weekends. The analysis showed a 28% increase in traffic volume following the road reconstruction. The current measure, which compares the difference in noise levels before and after the road reconstruction, indicates that while noise levels have decreased, they still exceed the normative values. For the same parameters, the median coefficient of exceedance decreased by approximately 17%, and the maximum coefficient of exceedance decreased by approximately 15%. The diagnostic usefulness of the coefficient of exceedance was further assessed using noise simulations based on the Cnossos-EU model. These simulations showed the high sensitivity of the proposed scalar noise measure to changes in vehicle speed and traffic volume. The simulations also indicated that to meet the Polish noise normative values, traffic volume would need to reduced by 50%, and the vehicle speed would need to be capped at 50 km/h. Additionally, the simulations suggested that even more stringent traffic restrictions would be necessary to meet the World Health Organization's noise recommendations.

Published: December 2024

This study focuses on evaluating microbial activity in Main Dolomite reservoir rocks (Zechstein, Wuchiapingian– Permian) at 100°C. Core samples from two wells, one potentially microbiologically active (C-1 well, 100°C) and the other considered inactive due to high temperature (L-1 well, 155.5°C), were analysed. The core from L-1, treated similarly to C-1, was used to control for contamination. Microbial experiments and molecular analyses were performed on both core samples to ensure accurate results unaffected by laboratory processing contamination. Microbial incubation tests were successfully employed to demonstrate microbial hydrocarbon degradation and methane formation from 13C-labelled acetate. A new method for staining microorganisms from rock samples was introduced to estimate biomass. The results indicated that microorganisms from the C-1 well exhibited both hydrocarbon biodegradation and acetoclastic methanogenesis during a 3-month incubation at 100°C. Fluorescence-stained and countable microorganisms were only observed in the C-1 samples, while no biodegradation or methanogenesis occurred in reference samples from L-1 well. The study provides valuable insights into microbial activities in extreme conditions, emphasizing the importance of proper controls and techniques to ensure accurate interpretation of results.

Published: December 2024

The study was focused on the characterization of microstructural evolution and microhardness in the plasma-sprayed and laser remelted Ni-Cr coatings with 20% addition of rhenium on stainless steel. The remelting process was performed with different laser power and laser traverse speed. The laser remelting process improves the quality of plasma sprayed Ni-Cr-Re coatings, reducing the porosity and the inhomogeneity of the chemical composition. The remelted coatings were characterized by a dendritic microstructure. Microsegregation of rhenium to dendrites was observed. The remelted coatings have an iron content of over 40%, which is the result of too deep remelting with the substrate material. The iron content in the remelted coatings increases with the decrease in laser speed, but the rhenium content decreases. All tested coatings were characterized by hardness similar to that of the substrate material.
Hydrogen Peroxide Modification Enhances the Ability of Metakaolin based Alkali Activated Materials Adsorbent to Remove the Ni2+ Ions
Authors: Ibrahim M. , Wan Ibrahim W.M. , Al Bakri Abdullah M.M. , Sauffi A.S. , Ahmad R.
Published: December 2024

The presence of nickel ions in wastewater is a significant environmental concern due to its toxicity, which can cause severe health problems. Metakaolin is a pozzolanic material that can be activated by alkali to produce a highly porous and reactive material that can be utilised as a heavy metal ion adsorbent. However, the adsorption capacity of metakaolin-based adsorbents is limited by their surface chemistry and porosity. Metakaolin-based alkali-activated materials adsorbent modified with hydrogen peroxide can effectively remove nickel ions from wastewater. The modification process increases the surface area and porosity of the adsorbent, enhancing its adsorption capacity. The modified adsorbent (1.00 wt.% H2O2) showed a higher sorption capacity of 26.57 mg/g and efficiency of 85.22% compared to the non-modified adsorbent (10.55 mg/g) sorption capacity and 45.63% nickel removal efficiency, indicating the potential of hydrogen peroxide-modified adsorbents as an economical and ecologically sustainable solution for environmental applications, particularly for metal immobilization.

Authors: Ju J. , Li R. , Xing X. , Jiang X. , Zhao G. , Lu F.
Published: December 2024

In this study, blast furnace dust and iron concentrate were used as raw materials and graphite as reducing agent for mixed compacts. The briquettes were roasted in a high temperature tube furnace at 1200°C and kept for a certain time to simulate the pre-reduction sintering dezincification process. The reduced briquettes were characterized by X-ray diffraction, scanning electron microscopy, Energy Dispersive Spectroscopy and flame atomic absorption spectrometry. The effects of C/O molar ratio, basicity and pre-reduction time on the zinc removal rate and pre-reduction degree of the pre-reduction sintered products were studied, and the removal mechanism of zinc was further investigated. The results show that the pre-reduction sintering process can effectively achieve the zinc volatility removal while meeting the requirements of subsequent blast furnace production. The zinc removal rate of pre-reduced sintered products increased with the prolongation of pre-reduction time, increased first and then decreased with the increase of C/O molar ratio and basicity. The pre-reduction degree and Zn removal rate showed the same variation pattern. When the briquettes with C/O molar ratio of 1.0 and basicity of 1.9 were reduced for 20 min, the zinc removal rate and pre-reduction degree could reach 90.40% and 87.74%, respectively, indicating that a large amount of zinc was removed and most of the metallic iron had been reduced. The research results can provide some theoretical basis for industrial production.

Authors: Vinod B. , Suresh S. , Sunil Kumar Reddy S.
Published: December 2024

Biocompatible materials are natural or man-made substances kept in the body to turn a living cell into a working organ. Bone tissue and biocompatibility are emerging as an alternative approach to regenerating bone due to some distinct advantages over autografting and allografting. This research aimed to fabricate a novel porous scaffold Ti-Nb-Zr-Sn alloy that can be utilized as a bone substitute. Ti-Nb-Sn-Zr were selected by different weight ratios and synthesized using the powder metallurgy method. Zirconium (Zr) is incorporated to get enhanced biological performance. The elements Ti, Nb with Zr, and Sn are utilized due to their excellent biocompatibility with the human body. The Ti-35Nb-7Zr-4Sn alloy has high tensile strength between 1042 and 1603 MPa by ­increasing Zr and Nb weight ratios. In addition, 35% Nb/7% Zr with 4% Sn composite show improved hardness, which is beneficial for resembling bone tissue and die-casting fittings in automobile applications. Fatigue and wear analysis is conducted to help us understand the behaviour of the Ti-Nb-Zr-Sn alloy.

Process Optimization Using Cuckoo Search Algorithm for the Manufacturing of Resin Transfer Moulded Composite Parts
Authors: Zade A. , Sridhar Babu B. , Kuppusamy R.R.P.
Published: December 2024

An in-house coded cuckoo search (CS) optimization algorithm integrated with a finite element simulation model was developed for resin transfer moulding (RTM) process optimization. At first, the mould filling and curing phases, the vital stages of the RTM process were modelled in the COMSOL multi-physics simulator for RTM6 resin – carbon fibre reinforced composite part. Then, the model was imported to the CS optimization algorithm scripted in MATLAB using the COMSOL live link for MATLAB. The CS algorithm was developed for the minimization of dry spot content by finding the optimal positions of gates and vents during the mould-filling stage and the minimization of the thermal gradient by finding the optimal mould temperature during the curing stage. From the optimization results, there was a decrease in dry spot content and thermal gradient with an increase in generations. With the generations, converged-stable-optimal solutions were obtained. A dry spot content of 3% for one gate and one vent and 0.56% for two gates and one vent was obtained for two-dimensional and three-dimensional composite plates, respectively. From the curing phase optimization results, a minimum thermal gradient of 0.86 K with 98.1% degree of cure was obtained for the optimal mould temperature of 433 K. The developed CS algorithm predicted the better-automated mould-fill and cure phase optimal solutions for the studied composite part.

Authors: Platon M.A. , Nemes O.
Published: December 2024

This study’s aim is to provide detailed information on how to control the mechanical behaviour of a short fibre unoriented composite material and adapt it for various applications. This study focusses on the challenging problem of recycling fibreglass waste mixed with thermoplastic polymers. The used method was thermoforming; preliminary studies have indicated this method as the most suitable for closing the loop in a manufacturing process – under the principles of a circular economy. Although this method is sustainable for this type of mixed waste, the research process is at an early stage and further studies and characterisations are required. From the data collected so far, this recycling method is the most efficient, both energetically and considering the added value of the final product. The results are encouraging and indicate a predictable behaviour of the studied reinforced composite material.

Authors: Akhir M.F.M. , Saad N.A. , Zabidi H. , Zainol M.R.R.M.A.
Published: December 2024

Alluvial aquifer are one of Malaysia’s most abundant groundwater resources, highly demanded in East Coast area. However, the presence of sulfur in these aquifers causes the emission of hydrogen sulfide gas. This research aimed to provide an alternative study for removing sulfur using marble filter media in a cascade column design, where water flows from the highest to the lowest column. Two groups of marble sizes were involved in this filter: pebbles and sand-sized particles. The treatment used raw groundwater with the highest concentration of total sulfur being 537.1 ppm. Sand-sized marble had the highest efficiency of sulfur removal, reaching 98.3% at a flow rate of 0.011 l/s. As a result of the effective filtration, the true color reached 33-34 pt/Co, significantly reduced from the source value of 1000-1012 pt/Co. The application of marble for treating groundwater with the sulfur issue is still novel and promising for groundwater filtration, potentially benefiting consumers facing this problem.
Feasibility Study of Metal Matrix Composite (In625-WC) Manufacturing by Laser Engineered Net Shaping (LENS®)
Authors: Rzeszotarska M. , Kunce I. , Zasada D. , Polański M.
Published: December 2024

The present paper focuses on the technological approach to manufacturing composite in the form of Inconel 625 reinforced with tungsten carbide particles. Twenty-four samples with reinforcement amounts ranging from 30 to 90% (wt.%) and different numbers of deposited layers were manufactured with the use of Laser Engineered Net Shaping (LENS®). The metallurgical quality, microstructure, chemical and phase composition as well as hardness of the produced composites were determined. Digital microscopy, X-ray powder diffraction and SEM-EDS were employed for this purpose. Despite numerous cracks, the fabricated samples exhibited a greater hardness than single-layer coatings of analogous composition also produced by additive techniques. This phenomenon is likely a result of repeated crystallization of the composites in remelted areas. A dual mechanism of material strengthening is observed in the additively manufactured composites, both by the presence of reinforcing particles and precipitates of secondary phases.
A Study of Strategies for Improving Interactivity in College English Classrooms in the Era of Intelligent Education
Authors: Fan Zehui
Published: December 2024

In today’s deep integration of new-generation information technology, such as cloud computing and big data, with classroom teaching, smart education is gradually emerging and increasingly becoming an inevitable trend of future education development. To fully prove that the smart classroom has a positive effect on the improvement of college English interactivity, this paper constructs a model of an English smart classroom. The iFIAS coding system is used to code the interactive behaviors of teachers and students in the classroom by recording English teaching videos. The smart classroom’s impact on English teaching interaction was analyzed by recording the frequency of each behavior and its corresponding frequency. The rate of student speech in traditional classrooms is about 10% lower than in smart classrooms, which suggests that smart classrooms promote active exploration and increase student engagement. After using the smart classroom, teacher 1, whose frequency of directly imparting knowledge decreased from 181 to 156 times, and the frequency of indirectly encouraging students to learn by complimenting them changed from 9 to 23 times. The smart classroom can improve the silent behavior that contributes to the classroom and increase students’ use of smart technology. To summarize, smart classrooms can improve the interactivity of English classrooms by influencing teachers’ and students’ speech, making English teaching more interesting and efficient.

Published: December 2024

Supply chain finance innovation can not only change the traditional way of capital flow but also promote the transparent sharing of information and facilitate high-quality economic development. The article uses blockchain technology to optimize the supply chain financial innovation mode and explains the role of supply chain financial innovation in economic growth. The input and output indicators are selected, and the principal component analysis is used to downsize the indicator data, and the downsized data are input into the DEA model to solve the efficiency change of the enterprise’s supply chain financial innovation performance. Additionally, a static and fixed model of supply chain financial innovation performance on the level of economic growth is constructed and example data analysis is performed. After implementing the supply chain finance innovation model optimized by blockchain technology, the enterprise’s accounts receivable turnover rate has increased by 9.19 times. A total of four years between 2012 and 2022 reached DEA effective, and the average value of comprehensive efficiency is 0.803. At the 1% level, the regression coefficient for supply chain finance innovation performance on enterprise economic growth is 0.173. The supply chain financial innovation model relying on blockchain technology helps to improve the level of enterprise economic development and boosts the rate of capital flow in the supply chain.
Application of econometric modeling to the impact of cultural industry policies
Authors: Fan Xiujuan
Published: December 2024

The study selected panel data from 30 provinces and cities in China from 2017 to 2023, quantified the cultural industry policy and its efficiency level using the PMC index model and the DEA-Malmquist index method, respectively, and then thoroughly investigated the impact of the cultural industry policy using the spatial Durbin econometric model. The regression coefficient of the direct effect of cultural industry policy, 0.0763, meets the significance test at a 1% confidence level. It shows that cultural industry policy can promote the development of the cultural industry. The spillover effect of cultural industry policies on the efficiency of the cultural industry is positive, suggesting that the cultural industry policies of neighboring regions can improve the efficiency of the local cultural industry. Further research reveals that the stronger the degree of marketization, the more the cultural industry policy promotes the efficiency of the local cultural industry, and it can positively influence the efficiency of the cultural industry in neighboring regions. Therefore, regions should pay attention to inter-regional balanced development when vigorously developing cultural industry policies and establish a sound, unified, open, competitive, and orderly market system to help realize the high-quality development of the cultural industry.
Research on Collaborative Interaction Mode of Intelligent Physical Education Teaching Based on Cloud Platform under the View of Digitization
Authors: Xu Renren
Published: December 2024

The cloud computing platform’s data and information sharing, computational efficiency, and service convenience provide strong support for collaborative learning and teaching and promote the high-level development of education digitalization. This paper designs a smart sports teaching system based on the collaborative cloud computing-assisted teaching platform, enabling a three-dimensional collaborative smart sports teaching mode. This paper focuses on the intelligent recommendation problem of sports learning resources and optimizes the teaching system by constructing a collaborative filtering recommendation model based on a graph convolutional neural network. The AUC, MRR, NDGG@1, and NDGG@2 index values and loss values of this paper’s sports learning resources recommendation model are 0.789, 0.904, 0.797, 0.934, and 0.54, respectively, which are better than PinSage, CASER, DIN, and MCR models. The model in this paper has shown that it can work by improving NDCG@2 and AUC values in a variety of sparsity learner groups in a way that is both effective and stable. The T-test P-values of the post-experimental badminton skill levels of the experimental group adopting the cloud-based 3D collaborative intelligent physical education teaching model and the control group adopting the traditional teaching model are all less than 0.05, which is a significant difference. This indicates that the physical education teaching mode in this paper is better than the traditional teaching mode and more conducive to improving students’ sports technology.

A Study of the Mechanism of Visual Communication in the Creation of Paintings in Public Art Programs
Authors: Chen Qing
Published: December 2024

Painting and public art no longer exist separately and in isolation but interpenetrate and integrate. The painting depicts and expresses objective objects through multiple painting languages such as chiaroscuro, color, texture, etc., while public art is an art of comprehensive display combined with venue, material and emotion. This paper analyzes the physiological structure of the human eye and the visual imaging system, integrates the mechanism of human visual attention into the perceptual construction process of public art painting creation, and then focuses on the research of the mechanism of stereoscopic perception and binocular perception of the human eye. On this basis, combining the spatial and temporal characteristics of the human eye to the creation of public art paintings, the visual communication mechanism of public art painting creation is explored from the three aspects of visual communication elements, paths and efficiency, and the subway mural creation is used as an example to analyze the feedback effect of visual communication. The results show that when the visual distance interval is 4~7, it is favorable to the visual communication of public art painting creation. In addition, focusing on the hue characteristics of the pattern color space while referring to the saturation and luminance characteristics for numerical analysis and quantification can be better for visual communication. Eye movement experiments show that higher color temperature scores are more in line with viewer preferences.
