Description:
Green industry development focuses on balancing economic and financial growth with environmental stewardship and ensuring that companies and industries are contributing positively to both environmental sustainability and prosperity. This manuscript aims to develop the novel technique of circular complex p, q-quasirung orthopair fuzzy 2-tuple linguistic (CCp, q-QOF2-TL) set and their operational laws based on algebraic t-norms and Hamacher t-norms, where the algebraic t-norms and Einstein t-norms are the special cases of the Hamacher t-norms for parameter ϜℲs=l and ϜℲs=2. Further, we derive the Hamacher power aggregation operators based on any finite collection of CCp, q-QOF2-TL numbers (CCp, q-QOF2-TLNs), called CCp, q-QOF2-TL Hamacher power average (CCp, q-QOF2-TLHPA) operator, CCp, q-QOF2-TL Hamacher power weighted average (CCp, q-QOF2-TLHPWA) operator, CCp, q-QOF2-TL Hamacher power geometric (CCp, q-QOF2-TLHPG) operator, CCp, q-QOF2-TL Hamacher power weighted geometric (CCp, q-QOF2-TLHPWG) operator, and described their basic properties, called idempotency, monotonicity, and boundedness. Further, we demonstrate the technique of multi-attribute decision-making (MADM) problem based on the above operators to evaluate the major factor that will be playing in the development of the green industry. Finally, we compare the proposed ranking values with the obtained ranking values of existing techniques to show the supremacy and superiority of the initiated approaches.

Mycoplasma hyopharyngis isolated from the joint of a weaner: A case report
Publication Name: Acta Veterinaria Hungarica
Publication Date: 2024-09-12
Volume: 72
Issue: 3
Page Range: 155-160
Description:
Background: Mycoplasma hyopharyngis is a commensal bacterium in the upper respiratory tract of swine. As it is recognized to be apathogenic, examinations regarding this species are scarce, compared to other swine mycoplasmas. However, in a few cases, M. hyopharyngis was detected in lesions of different organs. This report presents a case study in which M. hyopharyngis (along with other bacteria) was isolated from the joint of a pig showing lameness. Case presentation: A Hungarian farm was repopulated with 250 gilts and 1,700 finishers after undergoing a complete depopulation and disinfection. Two days later, cases of diarrhoea and septicaemia caused by Salmonella enterica serovar typhimurium were seen in the finishers. At the same time, following the first farrowing, swollen joints were observed in 21-25 days old piglets. Joint samples were collected, and isolation of Mycoplasma sp. and other bacteria was attempted. Analysis of the joint samples revealed the presence of Staphylococcus haemolyticus, Staphylococcus hyicus, Aerococcus viridans, Trueperella pyogenes, Streptococcus agalactiae and M. hyopharyngis. Conclusions: This is the second isolation of M. hyopharyngis from joints, which highlights the necessity of a better understanding the biology of this often-overlooked species, and its role in the progress of arthritis or other lesions.

Digital data (protection) Security - A contestable and fair digital market ecosystem
Publication Name: ACM International Conference Proceeding Series
Publication Date: 2024-09-12
Volume: Unknown
Issue: Unknown
Page Range: 247-251
Description:
The topicality of the thesis is given by the new interoperability provisions of the recently enacted legislation on contestable and fair markets. In interpreting the role of interoperability, the study takes as a conceptual starting point the ability of different IT-based systems to work together, bearing in mind that in digital markets interoperability is a direct economic determinant of interoperability between platforms and third-party access. Gatekeepers as digital platforms have become a dominant phenomenon in our world, which may be extremely heterogeneous, but almost without exception they can be identified as having a number of interdependent technological, economic and social dimensions of coordination. It is true that the last few decades have seen the recurrence of legal issues relating to the management of data, but these are primarily constitutional approaches in the context of the individual's right to self-determination. Furthermore, it is a fact that enforcement and regulation have not kept pace with the development of extreme market concentration, nor with the achievement of transparency or accountability. The thesis takes a novel approach in several respects. On the one hand, it takes a power approach to the new world of digital sovereignty that has emerged in the last decade, and on the other hand, it uses the latest findings in systems theory and data science to present a specific approach that, in the current state of technological development, self-determination is no longer necessarily adequate to protect our data. We all have to come to grips with the idea that our data, traces of our behaviour, have become an asset that may be being processed and analysed by someone, somewhere. That does not make privacy 'dead' as many people think - it is simply that the focus may be on the rules for handling personal data rather than protecting it.

FinTech Solutions Supporting Sustainable Agriculture - Lessons from Africa: FinTech Solutions Supporting Sustainable Agriculture
Publication Name: ACM International Conference Proceeding Series
Publication Date: 2024-09-12
Volume: Unknown
Issue: Unknown
Page Range: 97-103
Description:
This paper explores the transformative role of FinTech solutions in enhancing agricultural productivity and financial inclusion in Sub-Saharan Africa, a region confronted by myriad challenges including fragmented economies, limited capital, climate adversities, and restricted access to financial services. Drawing upon empirical examples, it delves into the potential of crypto-assets and blockchain technology to address these issues, spotlighting the rapid growth of the FinTech industry as a disruptive force capable of revolutionizing financial accessibility for rural communities. Through a comprehensive literature review and case studies, the study highlights innovative FinTech applications, such as mobile money services, which have significantly contributed to financial inclusion among smallholder farmers, facilitating access to savings, loans, and insurance products. The paper presents two pioneering initiatives from Kenya - the blockchain-based insurance model, Etherisc, and Agri-wallet, a digital wallet solution, demonstrating their effectiveness in mitigating risks associated with agriculture and enabling efficient financial transactions; and a central information-operator from Ghana, the Esoko. Furthermore, it identifies existing barriers to the wider adoption of FinTech solutions, including infrastructural deficits, legal uncertainties surrounding smart contracts, and the limited penetration of internet services, underscoring the imperative for enhanced digital infrastructure and regulatory frameworks to maximize the benefits of digital technologies for sustainable agriculture. The findings suggest that, despite challenges, the integration of FinTech in agriculture presents a promising avenue for boosting productivity, ensuring food security, and fostering economic resilience among rural populations in Africa. The paper calls for concerted efforts by stakeholders to address the digital divide and create enabling environments for the deployment of innovative financial technologies, paving the way for a more inclusive and sustainable agricultural sector.

Thermoplastic Starch Processed under Various Manufacturing Conditions: Thermal and Electrical Properties
Publication Name: Biomacromolecules
Publication Date: 2024-09-09
Volume: 25
Issue: 9
Page Range: 5938-5948
Description:
Eco-friendly materials like carbohydrate-based polymers are important for a sustainable future. Starch is particularly promising because of its biodegradability and abundance but its processing to thermoplastic starch requires optimization. Here we developed thermoplastic maize starch materials based on three manufacturing protocols, namely: (1) starch/glycerol manual mixing and extrusion, (2) starch/glycerol manual mixing, extrusion, and kneading, (3) starch/glycerol/water manual mixing and kneading. The physical properties were investigated by differential scanning calorimetry, thermogravimetric analysis, and broadband dielectric spectroscopy. As expected from a partially miscible blend, the dielectric spectra revealed two distinct α-relaxations for the glycerol-rich and the starch-rich phases, respectively. By employing kneading after extrusion, the miscibility between the two phases was found to improve based on thermal and dielectric methods. Moreover, the addition of water during the premixing stage was observed to facilitate phase separation between starch and glycerol, with the α-relaxation dynamics of the latter being comparable to pure glycerol.

Publication Date: 2024-09-06
Volume: 59
Issue: 1
Page Range: 63-73
Description:
The study aims to investigate how the transfer of matrix materials from eroded asbestos cement products induces stress responses in plants. The paper evaluates the exposure and risk factors of plants, water, and soil to asbestos cement materials. Additionally, the experimental results provide empirical evidence for plant stress responses based on physiological and germination parameters. Contamination of irrigation water with asbestos cement raises environmental concerns due to its potential toxicity to plants and soil quality. Asbestos in irrigation water can lead to toxic stress for plants, affecting germination processes and growth. The paper analyzes the effects of preset doses of irrigation water containing asbestos cement matrix on the germination process and physiological parameters of Solanum lycopersicum in a controlled experiment setting. This research proposes methodological developments that could be valuable for environmental plant protection professionals.

Publication Name: Applied Engineering Letters
Publication Date: 2024-09-01
Volume: 9
Issue: 3
Page Range: 146-161
Description:
The need to grow in a secure and tranquil environment demands the efforts of an armed force, and only with a strong-armed force can a country ensure its national security. In military activities, communication devices are widely used to confuse enemies' radars or communications to abandon their strategies and execute planned actions. The range of communication devices depends mainly on the antennas used. Army sustainability goals are to upgrade the effectiveness of the mission, reduce army environmental impact, build green sustainable structures, and attain the energy level independence that improves the continuity of operations which are indispensable to the mission. The primary goal of this paper is to present an innovative mathematical model for selecting pertinent antennae in communication devices using an innovative idea called a Complex Linear Diophantine Fuzzy Soft set based on the various attributes by incorporating decision-making techniques. Also, some of its beneficial operations such as Complement, AND, OR, Extended Union, and Extended Intersection, are presented in concert with the properties and theorems to apprise the viability of the proposed paper. This concept is more applicable and necessary to assess real-life situations using mathematical modeling.

Selection of straw waste reinforced sustainable polymer composite using a multi-criteria decision-making approach
Publication Name: Biomass Conversion and Biorefinery
Publication Date: 2024-09-01
Volume: 14
Issue: 17
Page Range: 21007-21017
Description:
The valorization of straw waste as a sustainable and eco-friendly resource in polymer composites is critical for resource recycling and environmental preservation. Therefore, many research works are being carried out regarding the development of wheat straw-based polymer composites to identify the reinforcing potential of these sustainable resources. In this study, three different sizes of wheat straw fibers (60–120 mesh, 35–60 mesh, and 18–35 mesh) were used, and their different ratios (0, 2.5, 5, 10, and 20% by weight) were systematically investigated for the physical and mechanical properties of polypropylene-based sustainable composites. The results indicated that the evaluated composites’ properties are strongly dependent on the quantity and size of the utilized wheat straw. Therefore, a preference selection index was applied to rank the developed sustainable polymer composites to select the best composition. Various properties of the composite materials were considered as criteria for ranking the alternatives, namely tensile strength and modulus, flexural stress at conventional deflection and flexural modulus, impact strength, density, water absorption, material cost, and carbon footprint. The decision-making analysis suggests the alternative with wheat straw content of 20 wt.% (35–60 mesh size) dominating the performance by maximizing the beneficial criteria and minimizing the non-beneficial criteria, making it the most suitable alternative. This study will significantly help formulation designers to deal with the amount and size issues when developing polymeric composites.
