Authors: Musa Sarah Safaaldeen , Al-Mukaram Noorance , Dakhil Ihsan Habib 
Published: January 2024

Abstract
In the last few decades, tyre rubber waste has been considered a risky issue to the ecosystem. A huge amount of used and deformed tyres is disposed of in landfill or recycled into other products. The main goal is to modify 60/70 bitumen grade to achieve 40/50 bitumen results. In this work, tyre rubber waste was added at different weights from 5 to 20% after cutting into small particles to use in the modification process of 60/70 asphalt binder. The modified asphalt was tested to meet the Iraqi standard specifications of roads and bridges. In the experimental work, Central Composite Design was applied to attain mathematical models that describes binder consistency by relating three operating parameters: tyre rubber ratio, mixing temperature and time. The predicted models relate to the penetration and softening point of the modified binder achieved R
2 of 97 and 99%, respectively. The obtained results indicated that the penetration and softening point improved after adding 20% recycled tyre rubber at 170°C and 20 min of mixing time.

Authors: Paape Nick , van Eekelen Joost A. W. M. , Reniers Michel A. 
Published: January 2024

Abstract
The poultry processing industry struggles to keep up with new developments in meat consumption and livestock breeding. Designing poultry processing systems is becoming increasingly more complex, and an increasing number of iterations of (re)design are required to optimize the product flow in these systems. To address this issue, this study presents a discrete-event simulation-based method for design space exploration of production systems. This method is mostly automated, greatly reducing the time and effort required in the design process. The steps that are automated are iterating on the design, model construction, performing simulation experiments, and interpreting the simulation results. An industrial case study in which a poultry processing system is redesigned is used to validate the effectiveness of the proposed method. A detailed description of this case study is given to showcase the different ways in which this design space exploration method can be used.

Abstract
In X-ray CT imaging, there are some cases where the obtained CT images have serious ring artifacts and noise, and these degraded CT images seriously affect the quality of clinical diagnosis. Thus, developing an effective method that can simultaneously suppress ring artifacts and noise is of great importance. Total variation (TV) is a famous prior regularization for image denoising in the image processing field, however, for degraded CT images, it can suppress the noise but fail to reduce the ring artifacts. To address this issue, the

Prenatal diagnosis of right aortic arch: associated anomalies and fetal prognosis according to different subtypes
Authors: Dizdaroğulları Gizem Elif , Alpınar Abdullah , Demirci Oya 
Published: January 2024

Abstract

Objectives
Right aortic arch (RAA) is a rare anomaly with an incidence of 0.1 % in the adult population and low-risk fetuses. Our aim in this study was to evaluate associated anomalies and conditions according to subtypes.

Methods
This was a retrospective study examining consecutive pregnancies diagnosed with RAA in our hospital between 2018 and 2022. Fetuses with RAA were divided into three groups, RAA with right-sided ductus arteriosus (RAA-RDA), RAA with left-sided ductus arteriosus (RAA-LDA), and RAA with a double aortic arch (RAA-DAA).

Results
A total of 81 fetuses were diagnosed as having RAA during the study period. The rate of cardiac anomalies (82.8 %) in the RAA-RDA group was higher than in the RAA-LDA (17.6 %) and RAA-DAA (22.2 %) groups (p<0.001). No statistically significant difference was found between the groups in terms of maternal age, diagnosis week, pregnancy outcome, extracardiac anomalies, and genetic anomalies. Three (8 %) of 36 fetuses with isolated RAA who resulted in live birth developed symptoms related to the vascular ring, and one (2.7 %) newborn with RAA-DAA underwent surgery.

Conclusions
The incidence of cardiac anomalies is high in fetuses with RAA-RDA. Ultrasound examinations should be performed for cardiac anomalies and additional structural anomalies. Vascular ring formation is a rare but important complication due to compression risk to the trachea and esophagus.
Mechanical and thermal properties of short banana fiber reinforced polyoxymethylene composite materials dependent on alkali treatment
Authors: Doğan Akar , Güneş Çağdaş 
Published: January 2024

Abstract
The present study aimed to develop a recyclable composite material based on a natural product, namely banana fiber, instead of synthetic reinforcement elements such as glass fiber or carbon fiber in thermoplastic matrix composites employed in many aspects of daily life. Polyoxymethylene (POM) thermoplastic was used as the matrix material. 3 %, 6 %, and 9 % by weight short natural banana fiber was used as reinforcement. Furthermore, the study improved the mechanical and thermal properties of the composite material with chemical improvements based on alkali treatment of banana fiber. Banana fiber and POM was initially mixed mechanically and then extruded at temperatures between 170 and 190 °C to obtain a homogeneous mixture. The mixture obtained by extrusion was initially cooled in the cooling pool and then passed through the crusher to obtain granules. These granules were pressed in plastic injection molds to obtain standard test samples. The ratio of reinforcement material and the variations in mechanical and thermal properties of the composites induced by the alkali treatment are presented in figures and tables. Furthermore, the changes in cross-sectional material images were examined with electron microscopy scans. The tensile and flexural strength of the material improved with alkali treatment.

Published: January 2024

Abstract
Q355 steel with Cu interlayer was bonded by transient liquid phase diffusion bonding (TLP-DB) at different bonding temperatures, and good bonding joints were obtained. The joints were characterized by optical microscopy, scanning electron microscopy and mechanical properties. The results show that there is a bending phenomenon caused by the difference of element diffusion at the bonding interface at the bonding temperature of 1050 °C. With the increase of the bonding temperature, the diffusion of Cu element plays a role in refining the grain, but with the increase of the bonding temperature, it will also lead to the overgrowth of the grain; At the bonding temperature of 1050 °C, there are obvious mutations in the diffusion of Cu and Fe elements, but the increase of the bonding temperature has a good effect on the interdiffusion of the elements. The mechanical properties test showed that with the increase of the bonding temperature, the hardness, shear strength, and impact toughness at the center of the joint increased first and then decreased, and all reached the maximum at 1100 °C. The electrochemical performance test showed that with the increase of temperature, the corrosion resistance of the joint also increased first and then decreased.

Abstract
Next-generation 6G communication holds the potential to revolutionize data transfer, enabling the realization of eXtended Reality (XR) with enhanced sensory experiences. To achieve this, advanced components such as high-performance intensity/phase modulators, waveguides, multiplexers, splitters, combiners, and filters operating in terahertz (THz) regime, specifically within the frequency range of 0.1–1 THz, are essential. However, existing microwave equipment and vector network analyzers designed for this frequency range suffer from limitations in resolution, stability, and accuracy when evaluating the intensity and phase responses of critical 6G THz devices. In this comprehensive review, we delve into the critical device requirements and emerging trends in next-generation 6G communication, essential performance evaluation parameters, comparisons between microwave and nano/microphotonic devices for testing, and the application of high-resolution THz sensors in 6G Internet-of-Things (IoT) scenarios. Notably, a frequency comb in the photonic regime emerges as the prime candidate for achieving precision evaluations of 6G networks and devices. Consequently, this review highlights the latest research in frequency comb measurements in the 6G THz frequency regime, with a particular emphasis on nano/microphotonic devices and metamaterials. The integration of frequency comb measurements into 6G and THz photonic devices and networks promises to accelerate the realization of high-density next-generation 6G communication.
Mobile app adoption comparison between U.S. and Chinese college students: information processing style and use frequency after download
Authors: Zhang Chenjie , Jiang Weiwei 
Published: January 2024

Abstract

Purpose
This study examines similarities and differences in information processing of college mobile app adopters, as age peers, in China and the U.S., by using the heuristic-systematic model as the main theoretical framework.

Method
An online self-administered survey was conducted.

Findings
The results confirm that some peripheral factors affect personal factors. Some cultural orientations (power distance, indulgence, individualism, and uncertainty avoidance) influence app adopting behavior indirectly via information processing. Social norms significantly predict information processing and adopting behavior. Respondents share similar heuristic processing but show significant differences in systematic processing, which results in significantly different adopting behaviors.

Implications
Some cultural orientations affect app adopting behavior through information processing, but affect heuristic processing and systematic processing differently. Not all cultural orientations influence the decision-making process, and some orientations may be moderators instead of predictors. Social norms can create strong social motivation in app adoption. Respondents are capable of processing information so perceived behavioral control is not a significant influencer in the decision-making of app adoption. Respondents are different in systematic processing but not in heuristic processing, which calls attention to cross-cultural comparisons in terms of information processing, researchers should test at the dimensional or item level before comparing at the variable level.

Value
This study extends the heuristic-systematic model by connecting peripheral factors (national culture, social norms, and perceived behavioral control) and personal factors (information processing and behavior). This study also tests the special roles of social norms and perceived behavioral control, which originated from the theory of planned behavior, as peripheral factors, and enriches the literature on information processing of decision-making. This study introduces the possibility that respondents are more different in systematic processing than heuristic processing and cultural orientations affect heuristic processing and systematic processing in different ways, and also sheds light on technology acceptance literature in terms of non-adoption.
Study on dynamic response of cushion layer-reinforced concrete slab under rockfall impact based on smoothed particle hydrodynamics and finite-element method coupling
Authors: Mei Xuefeng , Wu Jianli , Wang Teng , Wang Ting , Liang Xiaofei , Wang Yanping , Li Bangxiang , Su Tian , Xu Lina 
Published: January 2024

Abstract
In the rockfall prevention and control project, the reinforced concrete (RC) slab and sand (gravel soil) soil cushion layer are commonly used to form the protection structure, thereby resisting the rockfall impact. Considering that the oversized deformation of the cushion layer under impact load using the finite element simulation cannot converge, this article establishes a numerical calculation model using smoothed particle hydrodynamics–finite-element method coupling (SPH–FEM). First, the standard Lagrange finite-element mesh is established for the whole model using ABAQUS, and then the finite-element mesh of the soil cushion layer is converted to SPH particle at the initial moment of the calculation, and finally the calculation results are solved and outputted. The results indicate that, compared with the results of the outdoor rockfall impact test, the relative errors of the rockfall impact force and the displacement of the RC slab are within 10%, which proves the rationality of the coupling algorithm; moreover, in terms of the numerical simulation, the SPH–FEM coupling algorithm is more practical than the finite element for reproducing the mobility of the rockfall impacting the sand and soil particles. In addition, at an impact speed of less than 12 m·s−1, the cushion layer is able to absorb more than 85% of the impact energy, which effectively ensures that the RC slab is in an elastic working state under small impact energy and does not undergo destructive damage under large impact energy; the peak impact force of the rockfall is approximately linear with the velocity, and the simulated value of the peak impact force is basically the same as that of the theoretical value of Hertz theory; the numerical simulation is good for reproducing the damage process of the RC slab in accordance with the actual situation. The SPH–FEM coupling algorithm is more justified than the FEM in simulating the large deformation problem, and it can provide a new calculation method for the design and calculation of the rockfall protection structure.
Wine as a “Cultural Product”? Ethnographic Notes on Work and Nationhood in the Republic of Moldova
Authors: Ana Elena-Daniela 
Published: January 2024

Abstract
The Republic of Moldova is one of the largest wine producers in Europe, and winemaking, both domestic and commercial, is deeply embedded in its society. State officials, wine marketing specialists, and subsistence winemakers in their discourses often tie wine and winemaking to a national framework, conceptualizing it as a “cultural product” that is typically Moldovan. The author makes use of ethnographic fieldwork to analyse how national identification becomes something salient among workers in the wine industry—if it does so at all—and what role nationhood plays in winemaking workers’ self-image. That wage work in winemaking means different things to manual workers and managers, and to subsistence winemakers. For the workers, their dependence on low remuneration and the division of the production process makes their work less a matter of national identification and “cultural production” than a purely instrumental activity.

Authors: Mahmuluddin Mahmuluddin 
Published: January 2024

Purpose of the Study: This article investigates how symbols and rituals contribute to conflict management in deeply divided societies. Methodology: Through qualitative library research, this study examines the impact of symbols and rituals on peace-building by analyzing theoretical frameworks and case studies. Main Findings: The study identifies that symbols and rituals play a crucial role in the peace-building process, achievable through two primary methods: the creation of new symbols and rituals that draw on inclusive narratives to foster a shared symbolic space promoting multicultural tolerance, and the creative manipulation of existing symbols and rituals to challenge and subvert historical power dynamics. Applications of this Study: The findings offer valuable insights for policymakers, peace-building practitioners, and community leaders engaged in conflict resolution and reconciliation efforts. By understanding the dual potential of symbols and rituals in peace-building, stakeholders can develop more effective strategies to address the underlying causes of division and promote enduring peace in divided societies. Novelty/Originality of this Study: This research contributes to the field by providing a comprehensive analysis of the transformative power of symbols and rituals in peace-building. It showcases how these cultural elements can be strategically leveraged to support reconciliation and unity, marking a significant advancement in the understanding of non-traditional mechanisms of conflict resolution and peace-building efforts.

The distribution of publications posted in the Elibrary for the period from January 1, 2012 to December 31, 2022, in the structure of a cognitive matrix of taxonomic characteristics for the analysis and assessment of primary health care in the Russian Federation made it possible to establish areas of scientific interest and identify gaps in specific areas and indicators characterizing its current and future development.Aim. To distribute scientific publications according to the relevant segments of the cognitive matrix of taxonomic characteristics for the analysis and assessment of primary health care in the Russian Federation.Material and methods. A database of 41824 publications was used, for which a triple review was carried out with the involvement of 9 experts selected according to appropriate criteria for level of education, work experience in the healthcare system, and academic credentials. At the first two stages, publications not related to primary health care, as well as duplicate publications, were excluded. At the final stage of reviewing, a selective analysis of publications was carried out, assessing the correctness of their distribution into the corresponding taxa of the cognitive matrix, followed by adjustment (if necessary).Results. A cognitive matrix of taxonomic characteristics has been generated for the analysis and assessment of primary health care in the Russian Federation, containing 30339 publications distributed across relevant domains, subdomains and primary health care indicators. The matrix is also presented in a heat map format, allowing an assessment of the most studied taxa of primary health care, as well as highlighting those areas in primary health care in which more research should be carried out to provide a basis and methodology for making informed decisions on its development.Conclusion. Systematized and ordered publications can serve as a basis for a wide range of users in the preparation of systematic reviews and other publications on specific domains, subdomains, primary health care indicators and universal health coverage principles. This study has shown the high efficiency of the cognitive matrix of taxonomic characteristics as a unified tool for aggregation or decomposition of features characterizing the development of primary health care in the Russian Federation.
