Geomorphological evidence inconvenient for the antecedent rivers of the Arun and Tista across the Himalayan range
Authors: Nakata Takashi , Kumahara Yasuhiro , Naik Sambit Prasanajit , Sakai Harutaka 
Published: September 2024

AbstractThe Arun and Tista Rivers, which flow across the Himalayas, are commonly known as antecedent valleys that overcame the rapid uplift of the Higher Himalayan ranges. To clarify whether the idea of antecedent rivers is acceptable, we investigated the geomorphology of the Himalayas between eastern Nepal and Bhutan Himalayas. The southern part of Tibetan Plateau, extending across the Himalayas as tectonically un-deformed glaciated terrain named as ‘Tibetan Corridor,’ does not suggest the regional uplift of the Higher Himalayas. The 8,000-m class mountains of Everest, Makalu, and Kanchenjunga are isolated residual peaks on the glaciated terrain composed of mountain peaks of 4,000–6,000 m high. The Tibetan glaciers commonly beheaded by Himalayan glaciers along the great watershed of the Himalayas suggest the expansion of Himalayan river drainage by glaciation. For the narrow upstream regions of the Arun and Tista Rivers with less precipitation behind the range, it is hard to collect enough water for the power of down-cutting their channels against the uplifting Himalayas. The fission track ages of the Higher Himalayan Crystalline Nappe suggest that the Himalayas attained their present altitude by 11–10 Ma, and the Arun and Tista Rivers formed deep gorges across the Himalayas by headward erosion.
Temperature effect on the kinetic profile of Ziegler–Natta catalyst in propene polymerization
Authors: Kolomazník Vít , Cejpek Igor , Skoumal Miroslav 
Published: September 2024

AbstractPropene polymerization kinetic profiles with a diether-based Ziegler–Natta MgCl2-supported catalyst were investigated in a stainless-steel batch reactor. The initial 10 min period characterizes various temperature levels with a constant volume of liquid propene. The lowest temperature level corresponds to the usual prepolymerization temperature (10 °C), and the highest level corresponds to the usual main polymerization temperature (70 °C). The effects of the starting temperature levels were evaluated through polymerization kinetic patterns computed namely from the second polymerization period carried out at 70 °C for the next 90 min. Based on the heat transfer data, the kinetic profiles were fitted to suitable semi-empirical equations derived from fundamental kinetic approaches using the first and second orders of the catalyst active sites decay. Both approaches adequately describe the dependence of the initial activities and deceleration constants on the temperature during the initial period.

Published: September 2024

Abstract
Background
Cosmetic tourism is an increasingly common phenomenon, both in Ireland and internationally. Complications associated with procedures performed abroad may manifest after the patient has traveled back to their home country with patients often presenting to local health services. Such complications can be infectious in nature requiring either antimicrobial therapy and/or source control in the form of wound debridement or radiologically guided interventional procedures.

Methods
Patients who had presented to a regional plastic surgery unit between September 2021 and December 2022 with complications related to aesthetic procedures performed outside Ireland were identified in this retrospective-prospective design. Medical records were reviewed to ascertain what procedures were performed, where the procedure had taken place, the nature of complications, and microbial culture and sensitivity results.

Results
Thirty patients were identified during the study timeframe, predominantly female (n = 28) with a mean age of 40.27 years (SD 10.6). Abdominoplasty was the most common procedure (n = 17), and Turkey was the most frequently cited destination (70%). Wound dehiscence accounted for the majority of complications (n = 18). Wound cultures were obtained in 80% (n = 24) of patients and a causative organism was isolated in 85% (n = 34) of cultures. Eighteen species of bacteria were identified and antimicrobial sensitivities were obtained for 16 of these. Antimicrobial resistance to commonly prescribed empiric antibiotics was noted in several isolates.

Conclusion
Post-operative infections related to cosmetic tourism are a growing concern in plastic surgery. The bacterial etiology is varied, and antimicrobial resistance poses significant challenges, highlighting the need for early intervention and wound cultures to guide effective management.

Published: September 2024

AbstractRecent publications emphasize the need to take greater account of differences in teaching quality between subjects. The empirical analysis of this topic requires a comparison of teaching quality in different subjects to distinguish generic aspects of teaching quality from subject-specific ones. In this paper, we compare teaching quality in mathematics and German lessons using observational data from primary schools in Switzerland (NMath = 319; NGerman = 237). Data were collected using an observation instrument reflecting the teaching dimensions of the MAIN-TEACH model, which was developed based on a synthesis of established observation frameworks. The dimensions of classroom management, motivational-emotional support, selection and implementation of content, cognitive activation, support for consolidation, assessment and feedback, and adaptation were tested for subject-related measurement invariance. With a two-fold measurement invariance approach, differences between the subjects were investigated at both a global and an indicator level. When applying alpha accumulation correction, no significant subject-related differences in factor loadings or intercepts were found. The factorial structure of our data was basically identical for the two subjects. The comparison of latent factor means revealed no mean differences between the subjects. We discuss the implications for both the MAIN-TEACH model and research into subject-related differences of teaching in general.
Comparative analysis between three theoretical approaches through empirical experiences at university level
Authors: Florensa Ignasi , Barbero Marta , Martínez-Planel Rafael 
Published: September 2024

AbstractResearch into mathematics education at university level includes a wide range of theoretical approaches. This poses considerable challenges to researchers in terms of understanding and harmonizing the compatibility and commensurability of those approaches. The research community has already problematised and studied these challenges using networking theories. The networking theories framework is taken as a starting point in this study to contrast different approaches and to broaden the comparison of different frameworks. In particular, three case studies framed in the Action, Process, Object, Schema Theory, in the Problem-Solving approach, and in the Anthropological Theory of the Didactic are analysed. The differences and possible similarities between the three with regard to the research questions addressed, their objects of study, their empirical bases, as well as their research ends are considered. The analysis offers an insight into the potential for collaboration and the networking of theories in the field of university mathematics education.
An Assessment of the Acceptability of Cervical Cancer Education Intervention Materials Among Healthcare Providers in Ghana
Authors: Bonnah Juliet , Williams Michelle S. 
Published: September 2024

AbstractCervical cancer is currently the second leading cause of cancer death among women in Ghana. Previous studies have identified lack of awareness, lack of perceived susceptibility, and stigmatizing beliefs as significant sociocultural barriers to cervical cancer screening among Ghanaian women. The purpose of this study was to assess the acceptability of evidence and theory-based, culturally relevant cervical cancer education intervention materials among Ghanaian healthcare providers. Central-location intercept questionnaires were completed by providers (n = 60) in the Greater Accra region of Ghana. Providers reviewed a poster, an audio message, and a brief educational video. The variables assessed included the reaction to the materials, the ability of the materials to attract the attention of the intended audience, the ability of the materials to communicate the main point of the cancer education message, and the reaction to cultural characteristics of the materials. The mean age of the providers (n = 60) was 30.6 years, and the majority (70.8%) were females. Most of the providers had a positive general reaction to the poster, audio message, and video. The majority found the materials to be motivating. Most of the providers found the information in the materials to be attention-getting, interesting, useful, direct/to the point, and related to someone like them. Very few providers (5%) indicated that they were confused by the images or messages used in the materials. The culturally relevant cervical cancer education materials were acceptable to Ghanaian healthcare providers. These materials may be effective in shared decision-making for cervical cancer screening.
Moment Capacity of Bolted-Side Plate for the Eaves Joint of Nested Tapered Box Beam Portal Frame

Published: September 2024

AbstractThe joints of cold-formed steel (CFS) portal frames with box sections are primarily formed either through stiffened welded connections or by bolted end plates, which typically involve costly full penetration butt welds. In New Zealand, CFS portal frames with nested tapered box beam (NTBB) sections are popular, and the joints of these portal frames are also formed through a bolted end plate system. In literature, it was found that welds in these joints are prone to cracking in the heat-affected zone (HAZ) under bearing opening moments (tension). Therefore, this paper focuses on proposing an alternative connection system (bolted-side plate) for eaves joints without any weld, aiming to reduce the overall cost of construction and increase construction speed. The performance (strength and stiffness) of these joints is mainly dependent on the geometric details of the bolted-side plate, which is limited in Australia/New Zealand standards (AS/NZ 4600). Herein, a non-linear finite element (FE) model was developed for the NTBB portal frame and validated against the experimental test results from the literature. Firstly, the validated FE model was used to investigate the feasibility of using bolted-side plates for NTBB portal frames and found that the bolted-side plate can increase the ultimate capacity of NTBB portal frame by 9%. A parametric study was then conducted by considering different geometric details of the bolted-side plates under both closing (gravity) and opening (wind uplift) moments. Finally, unified design equations for the moment capacity of bolted-side plates were proposed based on the results of the parametric study, and their accuracy was assessed through reliability analysis.
A compass for sustainability? Semiconductors, rare earths and CSR: the case of onsemi
Authors: Gatto Andrea , Nuta Alina Cristina 
Published: September 2024

AbstractSemiconductors are a rampant ICT sector utilized in everyday life for electronic devices. This industry provides plentiful income to multinational corporations (MNCs) but has been put in the spotlight for its tremendous social, ecological, and political impact. The figures become dramatic in sub-Saharan Africa and developing countries, which have abundant resources but poor working conditions and abrupt environmental degradation. In this interplay, rare earths have become leading assets for companies and governments and are highly debated for their controversial nature; thereby, corporate social responsibility (CSR) and environmental practices turn pivotal. This work aims to connect the bountiful industrial sector of semiconductors with rare earths governance and CSR. To this end, this inquiry critically scrutinizes these three assets, analyzing the case study of onsemi as a business case and launching selected strategic and policy perspectives. This paper reviews these three concepts and conducts a content analysis on onsemi CSR Report and Annual Sustainability Report. The literature review emphasizes the increasing importance of these three topics within the mineral economics and sustainability research. The company analyzed produced cogent reports but supplementary information is needed to better understand its results within the semiconductors and extractive industry. This may help determining key achievements and areas for improvements in the private sector for REE sustainability, CSR and environment, social and governance (ESG) results and disclosure. The availability and governance of rare earths will determine decisive sustainability directions of utmost priority for geopolitical equilibria. The undertaken corporate and institutional strategies will lean toward dramatically diverse scenarios.
A Systematic Literature Review on Flexible Strategies and Performance Indicators for Supply Chain Resilience
Authors: Paul Ananna , Saha Suvash C. 
Published: September 2024

AbstractSupply chain resilience is a widely useful concept for managing risk and disruption. Designing strategies for preparedness, response, and recovery can help businesses to mitigate risks and disruptions. Among them, flexible strategies can effectively improve supply chain resilience. In the literature, several studies have considered different types of flexible strategies and investigated their impacts on supply chain resilience. However, a systematic literature review (SLR) paper on this topic can further help to understand the scientific progress, research gaps, and avenues for future research. Hence, this study aims to explore how the literature has contributed to the area of flexible strategies and the impact on supply chain resilience performance. To achieve our objective, we apply an SLR methodology to identify themes such as research areas and key findings, contexts and industry sectors, methodologies, and key strategies and performance indicators in the connection between flexible strategies and supply chain resilience. The findings show that many studies connect flexible strategies to supply chain resilience. However, research gaps exist in analysing relationships between flexible strategies and performance, conducting comparative studies, developing dynamic resilience plans, applying flexible strategies, conducting theoretically grounded empirical studies, and applying multiple analytical tools to develop decision-making models for supply chain resilience. Finally, this study suggests several future research opportunities to advance the research on the topic. The findings can be a benchmark for researchers who are interested in conducting research in the area of flexible strategies and supply chain resilience.
Comparing the technical quality and clinical outcomes of root canal treatment on immature permanent incisors in children: a retrospective evaluation of three bioceramic plug materials
Authors: Donnell Christopher C. , Kandiah Pathanjali 
Published: September 2024

Abstract
Purpose
To assess the technical quality and clinical outcomes of non-surgical endodontic treatment of immature permanent incisor teeth with three different bioceramic plug materials and highlight variables which may influence treatment and quality outcomes.

Methods
This cross-sectional analysis forms part of a retrospective service evaluation of the technical quality and clinical outcome of orthograde root canal treatment carried out in the Paediatric Dentistry Department of Charles Clifford Dental Hospital (United Kingdom). Twenty-five cases were identified chronologically, using the electronic patient record system, for three bioceramic plug materials: Mineral Trioxide Aggregate (MTA), Biodentine, and TotalFill Putty. All radiographs were analysed using standard conditions. Intra- and inter-examiner agreement was calculated using Kappa and weighted Kappa tests. Data were collected using a data collection tool, entered into Microsoft Excel, and analysed using descriptive statistics, exploratory analysis with Chi-squared tests, and multivariable analyses (logistic regression).

Results
At 12-month review, the success rate for each apexification material was MTA (84%), Biodentine (88%), and TotalFill Putty (92%). MTA had the highest frequency of post-operative coronal discolouration, with Biodentine most associated with apical extrusion. A number of variables and trends that affect the clinical outcome were identified, including the presence of pre-operative resorption, the number of operators involved in treatment, the number of appointments to complete treatment, as well as how non-use of local anaesthetic during apical plug placement had no adverse effect on technical quality or clinical outcome.

Conclusions
MTA, Biodentine, and TotalFill Putty are highly effective apexification materials which produce excellent clinical outcomes. As such, logistical and situational factors, such as continuity of care from operators with increased levels of experience, skill and ability, rather than material choice, may be more prognostic regarding the technical quality and clinical outcome of immature endodontic treatment. Further high-quality evidence is required.
La radioligand therapy (RLT) nei tumori neuroendocrini
Authors: Badrane Ilham , Urso Luca , Nieri Alberto , De Rimini Maria Luisa , Bartolomei Mirco 
Published: September 2024

SommarioI tumori neuroendocrini (NET) sono un gruppo di neoplasie rare e spiccatamente eterogenee, spesso diagnosticate già in fase avanzata. Sulla scorta dei risultati dello studio NETTER-1, la terapia con radioligandi (RLT) è stata approvata da EMA, FDA e, nel 2019, da AIFA, diventando un pilastro nel trattamento dei NET gastro-entero-pancreatici (GEP-NET) ben differenziati (G1 e G2), localmente avanzati o metastatici e in progressione al trattamento di prima linea con gli analoghi dei recettori della somatostatina (SST-R). Nonostante l’efficacia e la sicurezza della RLT nei NET sia ampiamente dimostrata da una ricca letteratura scientifica, permangono ancora alcuni interrogativi irrisolti. Tra di essi, i principali sono la definizione del corretto timing rispetto ad altre terapie e l’estensione alle cosiddette neoplasie orfane di RLT. Parallelamente si stanno sviluppando nuove strategie radiofarmacologiche per potenziare il modello teragnostico attualmente in uso. In questa rassegna verranno descritte le tappe fondamentali che hanno portato all’approvazione della RLT nei GEP-NET e verranno discusse criticità attuali e prospettive future di tale approccio terapeutico.

angles. The investigation is performed on both hot-extruded single filaments and 3D-printed specimens. Experimental results of hot-extruded single filaments are utilized on the microscale to extract the macroscale constitutive models. At the microscale level, representative volume elements with different percentages of penetration are analyzed to compute the effective orthotropic elastic material properties. A comprehensive comparison study is conducted using different micromechanical models, multiscale simulation outputs, and the mechanical properties resulting from experiments. The accuracy of the results obtained from the homogenization technique is validated against realistic finite element microstructural models and experimental measurements. The results demonstrate that computational homogenization, when coupled with accurate property characterisation, serves as a reliable tool for predicting the elastic response of 3D-printed parts. Furthermore, the proposed framework reduces the need for extensive experimental replication and lowers manufacturing costs.
Towards online training for RL-based query optimizer

Published: September 2024

AbstractJoin query optimization aims to find the best join order for tables in a query, which is critical for query processing performance. Recently, reinforcement learning models have been proposed to solve the challenges existing with query processing and join query optimization. However, changes in the data distribution can turn the trained reinforcement learning models into obsolete models, resulting in longer execution times. In this paper, we propose a new training strategy in order to extend the existing reinforcement learning models and improve their adaptation when the data distribution changes. The experiments show that the proposed strategy has a significant benefit in decreasing training time for the models given the changes in the data distribution.
Inverse Problems for One-Dimensional Fluid-Solid Interaction Models
Authors: Apraiz J. , Doubova A. , Fernández-Cara E. , Yamamoto M. 
Published: September 2024

AbstractWe consider a one-dimensional fluid-solid interaction model governed by the Burgers equation with a time varying interface. We discuss the inverse problem of determining the shape of the interface from Dirichlet and Neumann data at one endpoint of the spatial interval. In particular, we establish unique results and some conditional stability estimates. For the proofs, we use and adapt some lateral estimates that, in turn, rely on appropriate Carleman and interpolation inequalities.
Advanced Regenerative Medicines for Rare Diseases: A Review of Industry Sponsors Investment Motivations
Authors: Ogbogu Ubaka , Nel Anja 
Published: September 2024

AbstractDespite regulatory changes designed to stimulate investment in therapies for rare diseases, many of these conditions lack government-approved treatments. Advanced regenerative medicines, which are therapies and clinical interventions aimed at healing or replacing damaged or defective human cells, tissues, and organs, offer great promise for addressing many rare diseases. A major challenge facing advanced regenerative medicines for rare diseases is securing financial support to assist in bringing a therapy to market. This paper describes the factors cited by pharmaceutical industry players globally for sponsoring the development of advanced regenerative medicines for rare diseases. The paper examines the motivations of 53 sponsors that meet the latter criteria. The motivations behind investments were broadly similar amongst sponsors and map closely onto regulatory requirements for clinical development and marketing authorization of advanced therapeutic products, including the presence of accelerated or attenuated pathways for regulatory approval, use for indications with high unmet medical needs, and/or that have advantages over existing therapies, and robust preclinical data. Other factors include availability of investment incentives and opportunities for off-label use in the post-approval stages.
