Authors: Freitas André , Matos João Filipe , Piedade João , Teodoro Vitor Duarte , Serradas Duarte Rosa 
Published: March 2024

Abstract
Despite the several mismatches of methodological understanding between teachers and students in higher education, research methodologies in education are a relatively common pedagogical practice in most European advanced courses in education. However, only some studies have shown what pedagogical practices are mobilised by the teachers with their specific scientific conceptions. This article presents and discusses the results of an extensive research study conducted in Portugal with all the teachers involved in teaching research methodologies on master’s and doctoral programmes in education. The results show the personal and professional characteristics of the teachers involved in this teaching and the type of senses, decisions, and challenges experienced when teaching research methodologies. The study identifies and characterises the research culture generated by the different pedagogical practices in this scientific field. Based on the results, we argue that the teachers’ scientific conceptions and pedagogical practices may be developed by a “peer authorial construction of research understanding,” aiming to provide appropriate educational experiences to students in research methodologies courses in advanced studies in education.
Distributed self-healing control of single-phase grounding fault in neutral point non-effective grounding system
Authors: He Silin , Zhu Jiran , Zhang Di , Liu Shengpeng , Zhan Luxin , Chen Chun 
Published: March 2024

AbstractIn distribution networks, single-phase grounding occurrences in non-effectively grounded systems do not result in short-circuits, thus leading to low fault currents. Particularly in high-resistance grounding scenarios, fault currents become extremely low, increasing the risk of protection misjudgments. To enhance the speed and accuracy of self-healing during such faults, a distributed self-healing control method based on flexible grounding and zero-sequence current analysis for non-effectively grounded systems is proposed. This method employs peer-to-peer distributed self-healing and flexible grounding techniques to convert isolated or arc-suppressed neutral systems to low-resistance grounded systems. Additionally, a localization criterion unaffected by neutral grounding modes is introduced, utilizing deviations in zero-sequence current upstream and downstream of the fault as distinguishing characteristics. The proposed method is straightforward in principle and leverages existing terminal equipment for accurate and swift fault processing. Simulation results validate the method’s resilience to transition resistance and neutral grounding conditions, demonstrating its suitability for single-phase grounding fault localization across all system types. The research findings effectively ensure the accuracy and swiftness of self-healing during single-phase grounding faults in non-effectively grounded systems.
Optimal evaluation of symmetry-adapted n-correlations via recursive contraction of sparse symmetric tensors
Authors: Kaliuzhnyi Illia , Ortner Christoph 
Published: March 2024

Abstract
We present a comprehensive analysis of an algorithm for evaluating high-dimensional polynomials that are invariant (or equi-variant) under permutations and rotations. This task arises in the evaluation of linear models as well as equivariant neural network models of many-particle systems. The theoretical bottleneck is the contraction of a high-dimensional symmetric and sparse tensor with a specific sparsity pattern that is directly related to the symmetries imposed on the polynomial. The sparsity of this tensor makes it challenging to construct a highly efficient evaluation scheme. Bachmayr et al. (“Polynomial approximation of symmetric functions,” Math. Comp., vol. 93, pp. 811–839, 2024) and Lysogorskiy et al. (“Performant implementation of the atomic cluster expansion (pace): application to copper and silicon,” npj Comput. Mater., vol. 7, Art. no. 97, 2021) introduced a recursive evaluation strategy that relied on a number of heuristics, but performed well in tests. In the present work, we propose an explicit construction of such a recursive evaluation strategy and show that it is in fact optimal in the limit of infinite polynomial degree.

Published: March 2024

Abstract
Indonesia is a significant producer of shallots, and the country frequently cultivates three distinct varieties: Bima, Trisula, and Sumenep. Each cultivar exhibits distinct characteristics, specifically when grown under suboptimal conditions. Several studies showed that insufficient watering intervals (WIs) can lead to drought stress, while excessive levels often lead to inundation. To investigate the effects of cultivar and WI on shallot growth and quality, this study employed a split-plot design with main plots and subplots with four repetitions. The main plots consisted of cultivars (Bima, Trisula, and Sumenep), while the subplots comprised WIs (once in 1 day, 2 days, and 3 days). The results showed that there was an effect of interaction between cultivars and WIs on growth (proline [126.15 mg 100 g−1]) and quality (quercetin [3.8739 mg g−1], rutin [0.2080 mg g−1], and kaempferol [1.209 mg g−1]). However, there was no effect on the number of tillers, shoot/root ratio, water content, number of tubers, tuber weight, and total flavonoid.

Abstract
Drainage in sugarcane cultivation in high-rainfall areas is of paramount importance because it affects sugarcane plants from planting, maintenance, and production. Poor drainage can damage plants and reduce productivity. This study was conducted at Bone Sugarcane Plantation, which typically has high annual rainfall; thus, drainage is necessary. The existing drainage channel cannot drain all surface runoff quickly and causes problems to sugarcane plants. Therefore, a study was conducted with the aim of designing the shape and size of drainage channels that can drain surface runoff quickly, have a strong structure, allows for an effective use of cultivated land by reducing headland for tractor turning, and maintains appropriate soil moisture. The research began by determining the saturated hydraulic conductivity of the soil using the Falling Head method. Surface runoff discharge was calculated using rational equations to determine the dimensions of the drainage channel. Rainfall intensity was determined from Intensity Duration Frequency curve which was constructed using Manonobe method. The results showed that the saturated hydraulic conductivity of the soil was 3.54 × 10−3 cm/s which is suitable with surface drainage. Rainfall intensity is estimated to be 201.33 mm/hour. The shape and dimensions of the drainage channel are parabolic with the largest width and depth of 1.70 m and 0.90, respectively. This study provides a practical method to solve drainage problems in sugarcane fields that apply full mechanization. In addition, the practical analysis used in this study can be adapted to analyze the design of drainage channel for other plantations or regions with similar constrains.
Group Grievances, Opportunity, and the Onset of Civil War: Some Theory and Tests of Competing Mechanisms, 1990–2017

Published: March 2024

Abstract
Recent scholarship claims that group grievances due to political exclusion and discrimination drive civil wars. The grievance perspective suggests that socio-psychological factors allow groups to overcome collective action problems. We argue that the grievance perspective (over)focuses on the ends and not means, which are critical to explain how groups survive state sanction, allowing contention to escalate to civil war. We suggest that inclusive economic governance reduces investment in state-evading infrastructures for quotidian economic reasons, leading to the buildup of rebellion-specific capital. Physical and human infrastructures of state evasion form the logistical bases for survival against state sanction. Our analyses show that group-grievance-generating political factors are poorer predictors of civil war compared with economic freedoms measured as free-market friendly policies and the private ownership of economies, which should reduce economic rents accruing to state-evading shadow markets. Our results are robust to several alternative models, data, and estimating method. Theory that ignores the means explain the main causes of costly violence only partially, or mistake symptom for cause. Freedom and inclusiveness, which should reduce grievances, are intrinsically valuable, but they are hard to obtain when violence is waged successfully for more narrower ends.
Analysis of a capacitance tomography system for object detection and localization
Authors: Affortunati Sabrina , Zagar Bernhard G. 
Published: March 2024

AbstractTo ensure safe human-robot cooperation, it is necessary not only to measure the force exerted during contact, but also to monitor an approaching action. This would allow avoiding any unintentional contact through evasive maneuvers and thus prevent possible injuries. In our contribution we analyze a localization system based on capacitance tomography where an approaching object constitutes an electrode of a multi-electrode capacitance. The system processes measured voltages made on the surface of a conductive layer. From this, the location of the capacitive coupling between the object and the layer can be reconstructed, and the position of the object can be estimated. The system’s performance is further analyzed using the Neyman–Pearson detector. To define the performance of the system, for object detection only, the influence of object distance, object area, and number of measurements used on the probability of detection is examined.

Abstract
NiTi-based memory alloys are often used as intracorporeal implant materials because of their superelasticity and shape memory properties. However, over time, the release of nickel from the NiTi alloy into the body becomes unfavorable; therefore, studies should be conducted to reduce the negative impact of nickel leakage. In this study, the biocompatible selenium element was used to coat NiTi alloys with different thicknesses. The coating process was performed using the thermal evaporation technique. Scanning electron microscopy-Energy Dispersive X-ray Analysis measurements revealed that the surfaces of the samples were well covered. Also, the atomic force microscope device determined the surface roughness of the alloys. The roughness of the surface increased after the coating process. The Tafel test was accomplished to determine the biocompatibility of the coated and uncoated alloys in an artificial body fluid. The corrosion test reveals that Se-coated NiTi alloys have high corrosion resistance.
Populism and Political Parties in Asia: A Comparison of Aam Admi Party (AAP) in India and the Liberal Democratic Party (LDP) in Japan
Authors: Nandy Debasish , Akon Md. Saifullah 
Published: March 2024

Populism is one of the most popular techniques used by Asian political parties. Political parties use this tactic through socio-political movements not only for the larger good of society but also for their own narrow goals. This article investigates two separate political parties from India and Japan. Populist policies have both beneficial and harmful effects on politics. The given promises often failed to address the grievances of the voters. A significant civil society movement propelled the Aam Admi Party (AAP) to political status. It began as a non-political entity and evolved into a political one. Following the formation of AAP, the issue of civil society as a non-political entity arose. The AAP is a regional party that holds power in two Indian states, focusing its populist policies on local issues. As a national party, the Liberal Democratic Party of Japan (LDP) is comparatively old and addresses pertinent national issues, like national security. The quality of politics and socio-economic dynamics of the two countries are different. This paper argues that populism as a tool cannot always be beneficial for the political culture of a country. The wide gap between the promises and implementation often creates discontent among the voters. This paper will attempt the delineate the different scenarios of the populist policies of the AAP of India and the LDP of Japan using the content analysis method.
Effect of sacubutril/valsartan on Tp-e, QT, QTc, Tp-e/QTc parameters in heart failure with reduced ejection fraction
Authors: Genç Ahmet , Yılmaz Öztekin Gülsüm Meral 
Published: March 2024

Purpose: The purpose of this study is to evaluate ventricular repolarization before, at the first month, and sixth month after Sacubutril/Valsartan, an angiotensin receptor neprilysin inhibitor (ARNI) treatment in heart failure patients with reduced ejection fraction (HFrEF).
Materials and Methods: We included 49 patients with HFrEF who switched to ARNI therapy. The 12-lead electrocardiography (ECG) was evaluated before ARNI therapy and also during the first and sixth months of the therapy. We evaluated demographic, clinical, and laboratory parameters, as well as medications and ECG data, including heart rate. Additionally, we examined QT, QTc, Tp-e, Tp-e calculated (Tp-ec), Tp-ec/QTc, Tp-e/QT, and Tp-e/QTc.
Results: After receiving ARNI treatment, ventricular repolarization indices were significantly reduced in the first and sixth months compared to before treatment. Specifically, the QTc values decreased from 457.6 ms to 443.8 ms, and the Tp-e/QT ratio decreased from 0.21±0.03 to 0.19±0.03. Additionally, the QTc values decreased from 457.6 ms to 444.9 ms, and the Tp-e/QT ratio decreased from 0.21±0.03 to 0.18±0.03. However, when the first and sixth months under ARNI treatment were compared, no significant difference was found (QTc: 443.8 ms vs. 444.9 ms, Tp-e/QT: 0.19±0.03 vs. 0.18±0.003).
Conclusion: ARNI treatment in HFrEF positively affected QTc, Tp-e, and Tp-ec intervals and Tp-e/QT, Tp-e/QTc, and Tp-ec/QTc ratios, which are indicators of ventricular repolarization. Moreover, this effect started in the first month and continued in the sixth month.

Purpose: Transport of neonates with critical congenital heart disease (CCHD) necessitates professional and experienced staff and, well-equipped facilities for both the procedure and post-operative care. In this study, we aimed to evaluate the effect of transport on operation time and survival in neonates with CCHD and determine the relationship between transport characteristics and clinical status.
Materials and Methods: A retrospective cross-sectional cohort study was conducted on all infants with CCHD who were transported to a university hospital between January 1, 2019 and December 31, 2019. Transport characteristics such as transport distance, accompanying healthcare provider, vital signs, oxygen saturation levels, prostaglandin E1 (PGE) use, and respiratory support were recorded. The effects of transport characteristics on surgery time, complications, and mortality were analyzed. The Society of Thoracic Surgeons-European Association for Cardio-Thoracic Surgery (STAT) Score was used to analyze mortality-related risks for congenital heart disease. They were compared with inborn newborns with CCHD.
Results: A total of 55 patients with CCHD were evaluated. Thirty-one newborns (56.4%) were inborn (Inborn group), and 24 newborns (43.6%) were transferred from another center (Outborn group). There was no difference between the groups in terms of gender, gestational age, birth weight, pre-operative time, and hospital stay. Although the Outborn group had fewer STAT Score categories, there was no difference in the 30-day survival or mortality rates. In the Outborn group, five patients (20.8%) with duct-dependent CCHD were transported without PGE treatment and six duct-dependent (25%) patients received oxygen during transport inappropriately.
Conclusion: The administration of PGE and oxygen therapies to specific transported infants was inappropriate. Therefore, referral or transport team members should be familiar infants with CCHD. The impact of transport on surgical timing did not yield a significant effect. However, similar mortality rates were observed in both groups, despite the Outborn group demonstrating lower STAT scores. This may indicate the significance of referring intrauterine transportation to experienced cardiovascular centers.

Purpose: This study aimed to investigate the relationships between parental attitudes throughout and after the divorce process, child’s gender, and mental health. Another objective of this study was to explore factors that may potentially affect the occurrence and progression of psychopathological issues in children whose parents have divorced.
Materials and Methods: The study involved 129 children and adolescents, ranging in age from 2 to 18 years, whose parents had officially divorced. Information was gathered using both a Sociodemographic Information Form and a Divorce Questionnaire. Psychiatric diagnoses were assessed based on the diagnostic criteria outlined in DSM-5.
Results: Majority of the sample (88.4%) exhibited one or more psychopathologies. The most prevalent psychopathology was attention deficit hyperactivity disorder (57.4%). The sex of the child did not have a significant impact on the presence of psychopathology. Logistic regression analysis revealed that the age of the child at the time of divorce were associated with an elevated risk of psychopathology in the child, while being female decreased the risk of psychopathology.
Conclusion: Divorce can be a mentally challenging life event for parents and children. During this process, it can be beneficial to seek professional support for the child’s mental health to proactively identify and address situations that could potentially impact the child's mental well-being
Comparison of nailfold capillaroscopy findings in COVID-19 survivors with and without rheumatic disease: a case-control study
Authors: Kaplan Hüseyin , Cengiz Gizem , Şaş Senem , Kara Hasan 
Published: March 2024

Purpose: The aim of this study was to evaluate the nailfold capillaroscopy (NFC) findings of patients with rheumatic disease and healthy controls (HCs) who survived coronavirus disease 2019 (COVID-19).
Materials and Methods: This study included patients with axial spondyloarthritis (axSpA), psoriatic arthritis (PsA), and rheumatoid arthritis (RA) who recovered from COVID-19 and HCs. NFC was performed for all participants. NFC findings of the three groups [patients with COVID-19 (group 1), HCs with COVID-19 (group 2), and HCs without COVID-19 (group 3)] were compared.
Results: A total of 142 individuals (group 1, n = 42; group 2, n = 50; group 3, n = 50) were included in the study. Hospitalization and oxygen therapy were more common in group 1 than in group 2. The median time from a severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-positive real-time polymerase chain reaction (RT-PCR) test to NFC was 10.3 (6.3–24.4) weeks in group 1 and 17.1 (6.1–44.9) weeks in group 2. All NFC findings did not differ among the groups except for capillary ramifications, which were higher in group 1 than in groups 2 and 3. Underlying rheumatic disease was the only predictor that was significantly associated with capillary ramifications.
Conclusion: The NFC findings of COVID-19 survivors with and without rheumatic disease were substantially similar to those of HCs who did not have COVID-19. Capillary ramifications may result from an underlying rheumatic disease in patients with axSpA, PsA, and RA.
Saponin rich Gypsophila eriocalyx Boiss methanolic extract (GEME) exhibit anticancerogenic effect against neuroblastoma cancer cell line (SH-SY5Y)
Authors: Niğdelioğlu Dolanbay Serap 
Published: March 2024

Purpose: Herein, we sought to determine whether of saponin rich Gypsophila eriocalyx methanol extract (GEME) would exhibit any anti-carcinogenic activity on neuroblastoma cancer cell line (SH-SY5Y).
Materials and Methods: We therefore determined GEME’s saponin composition using LC-MS analysis, its impact on cell viability using MTT analysis, flow cytometry, and to find out its impact on apoptosis using qRT-PCR analysis.
Results: In the LC-MS analysis we determined that GEME contained high amounts of saponin (0.05-0.48 µg/g). We determined that GEME had an IC50 dose of 100 μg/mL at 48 hours. GEME had the effect of substantially increasing the percentage of apoptotic cells (5.19% and 65.21%) and disruption of mitochondria (46.18%). We also demonstrated that BCL2 gene expression (2.76 fold) was significantly reduced than that of the control while BAX (2.21 fold), CASP3 (2.43 fold), CASP7 (2.98 fold), CASP8 (2.23 fold), CASP9 (2.78 fold), and CYCS (2.12 fold) genes were expressed significantly higher than those of the control.
Conclusion: Considering the findings, it becomes clear that saponin-rich GEME stands out as a significant anticarcinogenic agent. Its remarkable efficacy is demonstrated through its capabilities to notably reduce cell viability, effectively trigger apoptosis, and significantly increase the rate of mitochondrial disruption in cancer cells.
