Published: July 2022

Abstract
The monosodium iodoacetate (MIA)-induced osteoarthritis (OA) may lead to cartilage degeneration and histopathological lesions. However, the correlation between inflammatory reaction and subchondral bone remodeling in a rodent osteoarthritic model is ambiguous. In this study, intra-articular injection of MIA was performed in 36 four-week-old specific pathogen-free male Wistar rats to induce OA. After 4 weeks of intervention, changes in intrinsic structural properties of the subchondral bones were measured, and the histological evaluation, as well as biochemical analysis, was conducted. We found that intra-articular injection of MIA increased chondrocyte apoptosis and promoted cartilage matrix degradation, such as cartilage surface defects and shallow or disappearing staining. MIA also induced inflammation, improved the expression of IL-1β, TNF-α, and matrix metalloproteinase, and decreased the expression of cartilage-specific proteins with the extension of modeling time. Meanwhile, the MIA also significantly accelerated the subchondral bone remodeling, as shown by the decreased subchondral bone density, thinning of trabeculae, disordered cartilage structure, and morphology. In conclusion, we have shown that MIA-induced rodent osteoarthritic model would cause decreased subchondral bone density, sparse trabecular bone, and other manifestations of osteoporosis accompanied by an inflammatory response, which would worsen with the progression of modeling time. Our results suggest that different phases of MIA-induced OA are associated with the changes in subchondral bone microstructure and the progression of local inflammation.
Fansubbers’ Subtitling Strategies of Swear Words from English into Arabic in the Bad Boys Movies
Authors: Al-Zgoul Omair , Al-Salman Saleh 
Published: July 2022

Abstract
This research investigates the strategies used by fansubbers to translate English culture-bound expressions into Arabic. It further investigates the functions of swear words and how the fansubber regenerated their functional connotations. The corpus of the study consists of English subtitles and Arabic fansubs of the Bad Boys movies. The researchers analyzed the data both quantitatively and qualitatively. The frameworks adopted in this research are the strategies proposed by Diaz-Cintas and Remael and the classification model of swear words presented by Ljung. The findings showed that the fansubber rendered the culture-bound expressions using seven strategies, the most dominant of which is omission at almost 37%. Other strategies varied in their percentage with: transposition, second-most utilized at 29%, followed by explicitation (25%), calques (8%), loanwords (0.2%), lexical creation (0.5%), and compensation (0.13%). The results showed that these strategies were sometimes wrongly used due to the lack of guidelines for fansubs. On the other hand, the dominant function of swearing used in the movie is the standalone one. Noticeably, the connotation of functional elements was often neglected by the fansubber. Thus, the fansubs were sometimes lacking in accuracy. Finally, the current research provides some implications and recommendations for translators when handling culture-bound expressions.
Correlation between lignin content and syringyl-to-guaiacyl (S/G) ratio of Eucalyptus globulus wood
Authors: Alves Ana , Rodrigues José C. 
Published: July 2022

Abstract

Eucalyptus globulus Labill is an important raw material for pulpwood for which low lignin content and high S/G ratios are important parameters. This work shows a highly significant positive and strong correlation between S/G ratio and acid-soluble lignin (ASL) content among E. globulus trees. Although significant, the negative correlation between the S/G ratio and Klason lignin is weak, and there is no correlation with total lignin content. The Klason residue has a lower S/G ratio than that of the original wood. This suggests that the contribution of the S units to the solubilisation of lignin in acidic conditions is not limited to the S units but also to the G units. This effect becomes more pronounced as the percentage of S units increases.
Numerical investigation of scrap melting in high-carbon hot metal

Abstract
Scrap melting in the steelmaking process has recently attracted considerable attention. This study developed a mathematical model to investigate the effects of sizes, initial temperatures and carbon contents of scrap, and bath flow on its melting behaviors. The results showed that the volume of the solidified shell on the melting interface could be decreased or eliminated by increasing the initial temperature of the scrap. The initial carbon content also significantly influenced the melting behavior. The completion melting time decreased from 253 to 80 s when the carbon content increased from 0.10% to 0.30%. Importantly, the natural convection or driven flow formed in the bath significantly influenced the melting behaviors. Moreover, the dominating factors changed as the melting proceeded. Therefore this study provides more insights into the melting behavior of the scrap during the steelmaking process at different operating conditions.

Symbolicity, language, and mediality
Authors: Elleström Lars 
Published: July 2022

Abstract
This article demonstrates the broad applicability of the concept of symbol in human communication, beyond but including verbal language. The starting point is Charles Sanders Peirce’s understanding of symbolicity as signification grounded on habits. The goal is to be able to conceptualize mediality in general and media interrelations, particularly in relation to symbolicity. Informed by a multimodal view on media, the author provides a systematic overview of symbolicity within the context of communication among human minds structured around two crossing parameters: symbols being limited or widespread among people and symbols not being part of or being part of systems – languages. Based on this overview, I clarify the role of culture in language notions and conceptualize language in relation to mediality. I also suggest a way of more precisely describing similarities and differences between languages and media types, without either conflating or totally separating the two concepts. Finally, I investigate how the dependence of language and media type conceptions on culture affects the idea of intermediality. Together, these investigations and conceptualizations promote a more comprehensive understanding of symbolicity in general and a deeper knowledge of the role of symbolicity in human communication, including verbal language, and intermedial relations involving all kinds of different media types.

Published: July 2022

Abstract
The virgin-asphalt-based joint materials of cement concrete pavement are subjected to damages because of repeated vehicle load and environmental factors. The styrene-butadiene-styrene (SBS), shape memory polyurethane (PU), and organosilicon (OS) modified asphalt-based joint materials were prepared to improve mechanical properties and pavement usability of virgin-asphalt-based joint materials of cement concrete pavement. The tensile, compressive, shear property, low-temperature ductility, high-temperature fluidity, and elastic recovery performance were tested to select a suitable modifier and confirm its dosage for preparing modified asphalt-based joint material. Results indicate that mechanical properties, ductility, fluidity, and elastic recovery of asphalt joint materials are improved by SBS, PU, and OS modifiers. Especially, the modification effect of PU modifier at the dosage of 8 wt % is most satisfactory, successively followed by OS and SBS. The PU at the dosage of 8 % is proposed to develop a new modified asphalt-based joint material, reducing the failures of joint material and improving the durability of cement concrete pavement.

Published: July 2022

Abstract
The precast concrete (PC) preform automatic production line basically has no supporting enterprise resource planning (ERP) system and can only communicate information in the traditional way, which reduces work efficiency. ERP is an application that automates the business process and provides insights on marketing strategy. Therefore, the information research of the intelligent PC preform automatic production line based on a genetic algorithm is proposed. First, the core architecture of intelligent PC preform automatic production is proposed, then the core business process of PC factory is described, and the preform ERP core module is designed from multiple perspectives. According to the characteristics of genetic algorithm, the quantitative factor and proportional factor of the intelligent PC preform automatic production line transportation speed are calculated, the time-division control model of intelligent PC preform automatic production line transportation speed is established, and the calculation process of the quantitative factor and proportional factor is substituted to control the transportation speed of production line by time division. The experimental results show that after testing the control effect of the conveying speed of the production line, the convergence speed of the motor speed waveform, and the stability of the model, the information conveying speed of the intelligent PC preform automatic production line can be controlled by time, according to the instructions, and it has faster corresponding speed, higher stability, and smaller error in the process of controlling the production line.

Abstract. In the beginning of the establishment of West Sumatra and its regencies or cities, it is never a woman elected as regional head. Since the regional elections in 2015, three women successfully contested the major elections, deputy major, and regent. The matrilineal system adopted by the people of West Sumatra, placing women in a central position, but cannot encourage women to be present as regional head. Through the qualitative research methods, this study tries to analyze what factors are the causes of women's insecurity as regional heads in West Sumatra. Then, by using the theory of political recruitment and the glass ceiling, the author finds the factors that women are not elected as regional heads due to the lack of commitment of political parties in West Sumatra in empowering female legislative candidates, in most of the people of West Sumatra, the patriarchal paradigm is still deeply rooted, traditional/cultural system, track record and strong money politics during the campaign period.Keywords: Women and minang politics, elections, matrilineal. Abstrak. Dari awal berdirinya Sumatera Barat beserta kabupaten/kotanya, belum pernah satupun perempuan yang terpilih sebagai kepala daerah dan sejak pelaksanaan pilkada langsung yang dilakukan pada tahun 2005 baru ada tiga orang perempuan yang berhasil ikut bertarung dalam pemilihan walikota, wakil walikota dan bupati. Sistem matrilineal yang dianut oleh masyarakat Sumatera Barat, yang menempatkan perempuan pada posisi sentral pun tidak dapat mendorong perempuan untuk hadir sebagai kepala daerah di sana. Dengan metode penelitian kualitatif, penelitian ini mencoba untuk menganalisis mengenai faktor-faktor apa saja yang menjadi penyebab ketidakterpilihan perempuan sebagai kepala daerah di Sumatera Barat. Menggunakan teori rekrutmen politik dan glass ceiling, penulis menemukan faktor-faktor ketidakterpilihan perempuan sebagai kepala daerah karena masih kurangnya komitmen partai politik di Sumatera Barat dalam melakukan pemberdayaan perempuan dalam hal ini melakukan perekrutan terhadap calon-calon perempuan, di sebagian besar masyarakat Sumatera Barat paradigma patriarki masih mengakar kuat, sistem adat/budaya, track record dan masih kuatnya politik uang pada saat kampanye.Kata Kunci: Perempuan Minang dan politik, pilkada, matrilineal.
Ideology, power, and progress: Economics and its dilemmas
Authors: Sturn Richard 
Published: July 2022

Abstract
The complex co-evolution of economics as a scientific discipline is accompanied by two dilemmas which are reflecting ambivalent effects of two ideologies: economism and scientism. Economics may go wrong when certain tendencies occasioned by those inevitable “ideological” influences are ignored. Pertinent problems include pseudo-rationalist conceptions of policy advice and the failure to deal with the limited status of partial analysis and abstractive dichotomies (notably allocation – distribution), the status of core concepts such as scarcity, instrumental rationality, exchange, and contract, as well as the related abstraction from power, distribution, and human sociality relevant for non-contractual interaction in various spheres of social life, including the market economy.

Circulating tumor DNA as a marker of minimal residual disease in non‑small cell lung cancer

Circulating tumor DNA (ctDNA) refers to small fragments of nucleic acid (approximately 166 base pairs) that are not associated with cells or cell fragments and circulate in the bloodstream. Circulating tumor DNA has been proven to be a marker of minimal residual disease (MRD), a tumor process that cannot be detected using routine investigations. Circulating tumor DNA can be used as a marker of MRD because tumor cells secrete their DNA into the blood during necrosis, apoptosis, and functioning (with extracellular vesicles, etc.); therefore, it is possible to detect it and identify MRD. Circulating tumor DNA accounts for 0,01 % to several percent of all circulating extracellular DNA depending on the size of the tumor, its vascularization and biological properties. Currently, much attention is paid to the detection of minimal residual disease after radical surgery for non‑small cell lung cancer (NSCLC), since a number of large studies have shown postoperative plasma ctDNA to be a negative prognostic sign. For example, Chaudhuri et al. showed that 36‑month relapse‑free survival (RFS) in patients with and without postoperative plasma ctDNA was nearly 0 % and 90–99 %, respectively. The status of MRD determined by postoperative plasma ctDNA levels may be potentially used for adjuvant treatment selection in the postoperative period. In the DYNAMIC study, MRD‑positive patients (with postoperative plasma ctDNA) who received adjuvant therapy had an RFS of 22,4 months while those who did not receive adjuvant treatment had an RFS of 9,3 months.Thus, the status of MRD based on the plasma ctDNA level after radical surgery may allow a personalized treatment approach for patients undergoing radical surgery for non‑small cell lung cancer (NSCLC).
