Abstract
It is very beneficial for wear resistance improving how to acquire refined precipitates with diffuse distribution. In high manganese cast steels, Ti-V-Nb microalloying is a useful method to promote carbide and carbonitride precipitating, and the nitrogen addition could accelerate the precipitation. Therefore, Aging time modification is a practical option to implement the precipitation strength and wear resistance of micro-alloyed high manganese steels. In this work, the quantities and distribution of precipitates were collaboratively regulated by Ti-V-Nb-N microalloying and aging time variations (water quenching at 1100°C followed by holding at 400°C for 24, 60, and 84 hours, respectively, designated AT24, AT60, and AT84) to improve the wear resistance of manganese steels. The results have shown that solid solution aging treatment could effectively refine micron-sized precipitates in high manganese steels compared to as-cast (AS) steels while inducing the precipitation of nanoscale precipitates. With increasing aging time, the number of nanoscale precipitates increased and then decreased, and the nanoscale precipitates were most numerous and uniformly distributed in AT60, which exhibited the most excellent comprehensive mechanical properties. Refined micron-size precipitates cooperating with diffusely distributed nanoscale precipitates increased the matrix resistance to abrasives resulting in less wear weight loss and improved wear resistance of AT60. Compared to as-cast steel, the wear mechanisms of the tested steels were transformed from wide and deep pits to shallow grooves and micro-cutting by prolonging the aging time.

Abstract

Background Pregnancy is associated with a higher risk of common bile duct stones. Currently Endoscopic Retrograde Cholangiopancreatography (ERCP) is the treatment of choice for symptomatic choledocholithiasis. However, ERCP during pregnancy is associated with hazards of radiation exposure, as well as challenging patient positioning and anesthesia. Aim of the study: It aimed to present our trial to overcome challenges in endoscopic clearance of symptomatic common bile duct stones during pregnancy. Patients and methods: This is a retrospective analysis of endoscopic CBD clearance in 27 pregnant patients with symptomatic choledocholithiasis between February 2019 and February 2023. Sedation and anesthesia was done by safe medications by senior anesthetist, and the endoscopic procedure was performed in left lateral decubitus instead of prone position. The gravid uterus was kept away from the monopolar electrocautery current pathway. Radiocontrast injection and fluoroscopy was deleted and replaced by trans-abdominal US and endoscopic bile aspiration. Data were collected, tabulated and analyzed by SPSS ver. 26. Result The patient’s age ranged from 18 to 36 years (Mean: 25 years). The mean duration of gestation ranged from 7–32 (Mean 15 weeks) and 17 patients were in the first trimester, 8 patients in the second trimester, and two patients in the third trimester). Therapeutic ERCP was successfully performed in all patients. The time of the procedure ranged from 19 to 45 minutes (Mean: 27 ± 13 min). As regards post-ERCP complications, one patient (3.7%) developed pancreatitis post-ERCP and was treated successfully with conservative treatment, and one patient (3.7%) with minor bleeding. All procedures were performed without any material adverse events immediately or on follow-up. There were no signs of fetal distress during any of these cases, and there were no fetal complications noted upon delivery or at 30-day follow-up. Conclusion Endoscopic clearance of symptomatic common bile duct stones during pregnancy can be obtained safely without fluoroscopy. Adjunct US and endoscopic bile aspiration can overcome the absence of fluoroscopy. Careful positioning of the patient, proper positioning of monopolar cautery pad, and judicious anesthetic modification are all crucial for patient and fetal safety.
Gaining insights on anyon condensation and 1-form symmetry breaking across a topological phase transition in a deformed toric code model
Authors: Huxford Joe , Nguyen Dung , Kim Yong Baek 
Published: December 2023

We examine the condensation and confinement mechanisms exhibited by a deformed toric code model proposed in [Castelnovo and Chamon, Phys. Rev. B 77, 054433 (2008)]. The model describes both sides of a phase transition from a topological phase to a trivial phase. Our findings reveal an unconventional confinement mechanism that governs the behavior of the toric code excitations within the trivial phase. Specifically, the confined magnetic charge can still be displaced without any energy cost, albeit only via the application of non-unitary operators that reduce the norm of the state. This peculiar phenomenon can be attributed to a previously known feature of the model: It maintains the non-trivial ground state degeneracy of the toric code throughout the transition. We describe how this degeneracy arises in both phases in terms of spontaneous symmetry breaking of a generalized (1-form) symmetry and explain why such symmetry breaking is compatible with the trivial phase. The present study implies the existence of subtle considerations that must be addressed in the context of recently posited connections between topological phases and broken higher-form symmetries.

and datafication within societies over the last years. In this context, the concept of data literacy has also gained in importance, as it is seen as one of the skills that citizens require in order to navigate and participate in society. However, despite the relevance of the concept, it is yet to be discussed as to the ways to promote it at the institutional level. In order to perform such a task, we conducted a review that combines approaches from a mapping review with that of a traditional narrative review, making a series of policy recommendations towards a data literate society. Focusing on the period between 2015 and 2021, we analysed a corpus of 39 empirical and theoretical studies. Findings confirm the scattered and interdisciplinary nature of research on data literacy, yet paving the way for a series of recommendations to promote the former.

Abstract

Managing stormwater in infiltration-based systems enables the interception of runoff suspended solids. Accumulated particles form a layer of stormwater sediments, the contamination of which presents a critical challenge for maintenance operations but is still insufficiently understood. This study therefore aims to characterize the main contamination patterns of stormwater sediments. Sediments were sampled from 18 infiltration basins encompassing a diversity of catchments. Eighty-five substances, including metals and six families of organic micropollutants, were targeted, almost all of which were consistently quantified. A significant accumulation relative to baseline levels was ascertained in all sites. The geochemical signature of stormwater sediments was relatively close to that of road dust, but different from continental and marine sediments, revealing the contribution of urban-specific sources of contaminants. Common emission and transfer dynamics were inferred from strong correlations between metals; same observations were made for alkylphenols and the group formed by polycyclic aromatic hydrocarbons, polychlorinated biphenyls, dioxins, and furans. The predominant land use was generally insufficient to explain the inter-site variability of sediment contamination, which could still be understood from an in-depth study of each catchment and the identification of site-specific emission sources. These results constitute a milestone toward stormwater sediment reuse as a resource.

Published: December 2023

Abstract
Water-related issues such as scarcity and pollution have become increasingly pressing in sub-Saharan Africa, especially Nigeria, highlighting the need for an effective environmental education (EE) programme. The relationship between EE and water pollution prevention and conservation in Nigeria remains an open question. Therefore, this study aimed to assess the role of EE in water pollution prevention and conservation in Nigeria. A simple random sampling was used to select 766 respondents from the southwest geo-political zone of Nigeria. Data were analyzed using simple descriptive statistics and analysis of variance. Results show a high level of awareness of water pollution and conservation strategies. However, people's attitude towards preventing water pollution and conservation was poor. Age does not significantly (at p &lt; 0.05) affect awareness and attitude towards water pollution prevention and conservation. However, the level of education significantly (at p &lt; 0.05) influences the level of awareness and attitude of people towards water pollution prevention and conservation. EE increases awareness and attitude towards water pollution prevention and conservation. Therefore, the Federal Ministries of Water Resources and Education should endeavour to make EE a compulsory programme in the school curriculum across all levels of education.

Climate variability in coastal regions presents significant challenges for salt farmer communities in their daily activities. This article aims to describe the impact of climate variability on salt farmer communities, as well as the livelihood strategy patterns they adopt in response to this variability. The study was conducted in Gampong Cebrek, Simpang Tiga Subdistrict, Pidie District, using qualitative methods. Data were collected through in-depth interviews and observations of specifically chosen salt farming communities. The findings indicate that these communities face difficult situations due to climate variability, including issues like flooding of fields during the rainy season, salt production difficulties, and vulnerable settlements. Adaptations include storing salt production soil in huts, raising the floor levels of homes and salt huts, and cleaning water channels. These challenges have led farmers to adopt strategies such as land intensification and extensification, livelihood diversification, and migration. Although these strategies are effective, migration, in particular, has negative impacts like the loss of future generations of salt farmers. Therefore, government support is needed to help salt farmer communities face the challenges of climate variability.
AbstrakVariabilitas iklim di wilayah pesisir menyajikan tantangan signifikan bagi komunitas petani garam dalam menjalankan aktivitas harian mereka. Artikel ini bertujuan untuk mendeskripsikan terkait paparan variabilitas iklim pada komunitas petani garam serta pola strategi nafkah petani garam dalam menghadapi variabilitas iklim tersebut. Studi ini dilakukan di Gampong Cebrek, Kecamatan Simpang Tiga, Kabupaten Pidie, menggunakan metode kualitatif. Data dikumpulkan melalui wawancara mendalam dan observasi pada komunitas petani garam yang dipilih secara purposive. Temuan menunjukkan bahwa komunitas ini menghadapi situasi sulit akibat variabilitas iklim, dengan masalah seperti banjir di lahan saat musim hujan, kesulitan produksi garam, dan pemukiman yang rentan. Adaptasi yang dilakukan termasuk penyimpanan tanah produksi di pondok, peninggian lantai rumah dan pondok garam, serta pembersihan saluran air. Permasalahan ini mendorong petani mengembangkan strategi adaptasi, termasuk intensifikasi dan ekstensifikasi lahan, diversifikasi nafkah, dan migrasi.

Oleh karena itu, diperlukan dukungan pemerintah untuk membantu komunitas petani garam menghadapi tantangan variabilitas iklim.
Pengaruh Daya Tarik Fisik terhadap Diskriminasi Pekerjaan di Industri Perhotelan dan Pariwisata Jakarta
Authors: Lestari Silmi 
Published: December 2023

This study aims to explore how standards of beauty and physical attractiveness influence job opportunities in the hospitality and tourism industries, particularly in the context of discrimination occurring in the initial stages of the job market, as reflected in job vacancy announcements. Utilising a reflective digital sociology approach, an analysis was conducted on job listings from the jobstreet.co.id portal, focusing on the hospitality and tourism sectors. The findings indicate that skills such as communication abilities, a good personality, and physical attractiveness often emerge as primary factors in the selection process. Notably, an attractive appearance is frequently considered an essential qualification and indicates a tendency towards discrimination at the initial stage of recruitment. This study finds that physical attractiveness is not only valued but also acts as a discriminatory factor, limiting job opportunities for those who do not meet subjective standards of beauty. These findings affirm that individuals with physical attractiveness are more likely to succeed in the hospitality and tourism industries compared to those who are less physically attractive.
