AbstractThis article presents the results of a nationwide survey addressing the status quo of gender equality and family friendliness within German interventional radiology (IR) with a focus on clinical entry and career development.All members of the German Society for Interventional Radiology and Minimally Invasive Therapy (DeGIR) were invited to participate in an online survey between November 2021 and February 2022. The survey consisted of 39 questions on demographic information, marital and parental status, experiences with entry and promotion in IR, family friendliness, and equality. A descriptive analysis of the responses was conducted.197 surveys from female (n=76; 39%) and male (n=121; 61%) interventional radiologists at various stages of training and career were analyzed. Fewer female attending physicians (58%) and chiefs of departments (23%) lived with children compared to male attending physicians (76%) and chiefs of departments (55%). Fewer men (4%) than women (41%) were primarily responsible for childcare. More female (55%) than male (6%) attending physicians worked part-time. Women rated entry into IR as more difficult than men. 55% of women felt disadvantaged by their gender (men: 6%); this was due to assumptions that women “perform less than men” (46%), “drop out due to family commitments” (35%) and that “men are promoted preferentially” (19%). 54% believed that it is more difficult for women to combine work and family. The reasons for this are “family commitments” and “lack of flexible work schedules and childcare”. Parents with primary responsibility spent less than 50% of their working time on clinical interventions. Fathers from a younger generation were more likely to take parental leave than fathers of a previous generation (52% vs. 17%). Similar numbers of men (51%) and women (55%) planned to work part-time in the future.There are gender-specific differences in the German IR. To ensure sustainable recruitment of young talent, measures such as the normalization of flexible work schedules should be introduced to create equal conditions for women and men, as well as mothers and fathers, and thus take changing (family) structures adequately into account.

Effect of Maternal Body Mass Index on N-Terminal Pro B-Type Natriuretic Peptide Levels in the Third Trimester
Authors: Saxena Upma , Yadav Priyanka , Lachyan Abhishek , Rani Anita 
Published: December 2024

Objective Maternal body mass index (BMI) and cardiac biomarkers, such as N-terminal pro-B-type natriuretic peptide (NT-proBNP), have been subjects of interest in obstetric research due to their potential implications for maternal and fetal health. Previous studies have explored the relationship between maternal BMI and various pregnancy outcomes, but the impact on NT-proBNP levels remains unclear. This study aims to investigate whether maternal BMI influences NT-proBNP levels in the third trimester of pregnancy, which could provide insights into maternal cardiovascular health during late gestation.
Study Design A total of 234 singleton pregnant women in their third trimester (28–40 weeks) were recruited from Antenatal Care Clinic. Exclusion criteria included preexisting cardiac or renal conditions, hypertension, diabetes mellitus, and other specific medical conditions. Participants were categorized into BMI groups (< 23, 23–24.9, 25–29.9, and ≥30 kg/m2), and their NT-proBNP levels were measured using quantitative enzyme-linked immunosorbent assay kits. Statistical analyses including Spearman correlation, chi-squared test, Kruskal–Wallis test, and regression analysis were performed to assess the association between maternal BMI and NT-proBNP levels.
Results The study population exhibited a range of BMI and NT-proBNP levels within normal ranges. No significant correlation was found between maternal age, parity, and NT-proBNP levels. Similarly, no significant association was observed between maternal BMI and NT-proBNP levels across different BMI categories. Trend analyses showed no consistent relationship between BMI and NT-proBNP levels. Multivariate and univariate regression analyses confirmed the lack of significant association between maternal BMI and NT-proBNP levels.
Conclusion Contrary to expectations, this study found no significant effect of maternal BMI on NT-proBNP levels in the third trimester of pregnancy. These findings suggest that factors other than maternal BMI may predominantly influence NT-proBNP levels during late gestation. Further research is warranted to elucidate the complex interactions between maternal physiology, BMI, and cardiovascular biomarkers during pregnancy.

High-Flow Nasal Cannula in a Parkinson's Disease Patient Undergoing Deep Brain Stimulation in the Awake State
Authors: Gupta Pragya 
Published: December 2024

AbstractThe administration of deep brain stimulation (DBS) in patients with Parkinson's disease is commonly carried out with the patient in an awake state with conscious sedation. However, maintaining the airway and preventing desaturation can be challenging during the procedure. High-flow nasal cannula (HFNC) has been deemed to be a safe option for providing respiratory support in such patients, affording multiple benefits. We report the case of a 48-year-old male patient with Parkinson's disease who underwent DBS, during which HFNC was employed for respiratory support. The patient tolerated the HFNC well, and the procedure was conducted without any complications related to respiratory function.
Epidural Blood Patch in Spontaneous Intracranial Hypotension and Role of Optic Nerve Sheath Diameter: A Case Report
Authors: Shah Dimple , Layek Sanghita , Das Bibhukalyani 
Published: December 2024

AbstractSpontaneous intracranial hypotension (SIH) is caused by spinal leakage of cerebrospinal fluid (CSF) and it is characterized by an orthostatic headache without a history of trauma or dural puncture. Patients may present with headache, there may be low CSF pressure, or imaging evidence of CSF leak. Epidural blood patching (EBP) has been considered as the mainstay of therapy for SIH. We report a case of SIH with bilateral subdural hematoma in a 63-year-old female patient who presented with sudden-onset headache for 4 days without any history of loss of consciousness, vomiting, or seizures. Lumbar EBP was given and it resulted in improved clinical features, imaging findings, and increase in optic nerve sheath diameter (ONSD) when compared with ONSD before EBP administration. EBP produces a tamponade effect and its efficacy results from sealing the dural defect by the injected blood, thus stopping the CSF leak.

Authors: Tyler Ian M. , Playford Phillip E. , Evans Katy A. 
Published: December 2024

Context Underlying geology strongly influences landforms, soil composition, and hydrogeology in Two Peoples Bay Nature Reserve, Western Australia, which was mapped by P. E. Playford in 1982. Aims To review the mapping of the Reserve, with the aim to better understand the geological history and landforms of the area. Methods In 2024, I. M. Tyler and K. A. Evans reviewed P. E. Playford’s mapping in the field, viewed aerial photography and geophysical imagery, and reviewed research published since 1984. Key results The oldest rocks are 1290 Ma granitic gneiss and an 1180 Ma granite intrusion. Amalgamation of the Meso- to Neoproterozoic Rodinian Supercontinent put the Albany−Fraser Orogen at the heart of east Gondwana for ~1.0 billion years. At 165 Ma, that plate configuration began to break up, and from 83 Ma, the Eucla Basin opened. Cenozoic landforms and surficial deposits record northward plate movement and collision with south-east Asia at around 23 Ma, causing tectonic uplift, sea-level change, and climate change. The middle to upper Eocene Plantagenet Group was deposited in a shallow marine embayment with Maardjitup Gurlin/Mount Gardner, forming an island. The uplifted Eocene sea floor was lateritized in the Miocene and is presently covered by Holocene eolian sand dunes, peaty swamps and lakes. Maardjitup Gurlin/Mount Gardner was connected to the mainland by Pleistocene eolianite deposits. Conclusions The influence of plate tectonics on the geological evolution of an area is profound, from the origin and composition of the oldest rocks to the present landscape and the youngest surficial deposits. Implications Understanding the geological history of an area is essential to understanding landscape evolution and the natural history of the flora and fauna that inhabit it.
Electrostatic potential of a uniformly charged disk through Green’s theorem
Authors: Sagaydak Alina E , Silagadze Zurab K 
Published: December 2024

Abstract
All existing derivations of the electrostatic potential of a uniformly charged disk are technically rather involved. In an old and now almost forgotten publication, Duffin and McWhirter proposed a method for calculating the electrostatic potentials of planar bodies by a skillful application of Green’s theorem. It is shown that this method significantly simplifies the problem of calculating the electrostatic potential of a uniformly charged disk and makes it an almost trivial task.
Nonreciprocal spin wave propagation in synthetic antiferromagnetic double domain walls
Authors: Ye Yuchen , Zhao Chenbo , Wang Jianbo , Liu Qingfang 
Published: December 2024

Abstract
Based on micromagnetic simulations, we demonstrate nonreciprocal spin-wave transmission in the double-domain wall waveguide within an artificial antiferromagnetic structure. Interestingly, the nonreciprocity of the upper and lower layers is opposite. By bringing the two domain walls closer via an external magnetic field, the resulting dipolar interaction causes energy transfer between domain walls. The chirality of the Néel wall in the lower layer is opposite to that of the upper layer, and the Dzyaloshinskii–Moriya interaction at the interface makes the nonreciprocal transmission of the lower layer opposite to that of the upper layer. Changing the frequency of spin waves can adjust the magnitude of the nonreciprocity. Our findings pave the way for the development of novel nonreciprocal magnonic devices.

= 0.0, 0.25, 0.50, and 0.75) have been synthesized via co-precipitation method by annealing at 900 °C. The nanocrystalline samples of compositions Ni0.25Fe0.75Co2O4 (D0.25) and Ni0.5Fe0.5Co2O4 (D0.5) crystallizes in a pure spinel phase, whereas Ni0.75Fe0.25Co2O4 (D0.75) show the existence of secondary phase of NiO, as confirmed by the x-ray diffraction analysis. The particle size and lattice strain in the samples both decrease as Ni substitution has increased. The field-dependent dc magnetization M(H) virgin curve measured at 5 K for sample D0.75 shows the existence of field-induced metamagnetic transition, while this behavior is absent in samples D0.5 and D0.25. Dynamic magnetic properties have been investigated by ac susceptibility measurement, which shows a strong frequency dependence behavior resulting from the blocking/spin-glass freezing states depending upon the amount of Ni substitution and the range of measurement temperature. High-resolution x-ray photoelectron spectroscopy analysis reveals the presence of mixed valence states of Fe2+/Fe3+, Co2+/Co+3, and Ni2+/Ni+3 in all samples. Using first principles-based density functional theory calculations with HSE06 exchange-correlation functional predicts the correct description of the ground state, which is ferrimagnetic and insulating in their inverse spinel case for D0.25, D0.5, and D0.75 samples that agreed well with our experimental observations. A closer look at the electronic structure near the Fermi level (E
F) of Ni-doped samples suggests a typical Mott–Hubbard insulating state while it is found to be a mixture of charge-transfer and Mott–Hubbard insulating state for parent compound FeCo2O4. The obtained spin-dependent gap hierarchy can have possible applications in spintronics. We have studied a detailed correlation between experiment and theory.

Published: December 2024

Abstract
A novel approach for estimating turbulent transport coefficients in fusion devices is presented. The diagnostic method is established on the analysis of the conditional variance of one-point time series of density or temperature fluctuations. It is tested on data obtained from probe measurements in the edge of the tokamak ASDEX Upgrade and the stellarator Wendelstein 7-X, and on synthetic data from the gyrofluid transport model GEMR. The approach demonstrates a remarkable degree of accuracy, typically within a factor of two of the actual transport measured by more difficult means. It is a simple and accurate way of evaluating turbulent particle and heat transport coefficients that does not require measurements of the velocity fluctuations.

Published: December 2024

Abstract
Titanium dioxide (TiO2) was prepared using the green synthesis method to investigate its photocatalytic activity in degrading methyl orange. The properties of TiO2 were analyzed using XRD to ascertain the phase and crystal size, SEM-EDX to evaluate the morphology and composition, and UV-Vis to measure the absorbance and bandgap energy. The study was conducted by varying the methyl orange (MO) solution concentration and ultraviolet (UV) irradiation time. The results indicated that the maximum degradation efficiency after 180 minutes was achieved at a concentration of methyl orange solution of 5 ppm with a value of 92.92%, while at concentrations of 15 ppm and 30 ppm, the degradation efficiency was 90.33% and 73.77%. Therefore, TiO2 has the potential to be an effective photocatalyst in the application of purifying water contaminated with dyes.

Published: December 2024

Abstract
Students’ conceptions sometimes differ from those of physicists, necessitating teachers to incorporate detection methods in their instructional planning to mitigate these disparities. This study aimed to create a 4-Tier Diagnostic Fluid Static Test (4T-DFST) tool and assess students’ conceptual understanding of static fluid topics. This research follows the Research and Development (R&D) approach, employing the ADDIE model (Analyzing, Designing, Developing, Implementing, and Evaluating). In essence, the four-tier diagnostic test format comprises four distinct levels. The instruments were deemed valid and reliable based on validity and reliability tests, yielding results of 0.60 and 0.79, respectively. Both expert validation and calculations confirm the suitability of the developed 4T-DFST for implementation. This research represents an advancement by focusing on static fluid material, whereas prior research concentrated solely on mechanics material with minimal attention to static fluid concepts.

Authors: Kurniawan A R , Suaebah E , Supardi Z A I 
Published: December 2024

Abstract
The time-dependent Schrödinger equation is fundamental to quantum mechanics, describing the evolution of quantum systems. This study introduces a novel numerical approach that extends and modifies the Crank-Nicholson method to solve the time-dependent Schrödinger equation. This method is designed to enhance both the precision and performance of computational results, especially in the context of quantum tunneling phenomena and applications that require high accuracy over long periods. To assess the precision and performance of the modified Crank-Nicolson method, we benchmark it against two well-known numerical methods: the Runge-Kutta method and the Split-Step Fourier method. Quantum tunneling is selected as the case study due to its relevance in quantum physics applications. Comparative analysis is based on numerical error metrics. The proposed method can be applied to other physical phenomena, expanding its potential application in physics research and technology industries.

Published: December 2024

Abstract
This research aims to develop a fluid, dynamic teaching aid for Senior High School. Visualization tools based on dynamic fluid materials. The method used in the research is the ADDIE development model (analysis, design, development, implementation, and evaluation). However, it is limited to ADD (Analysis, Design, and Development). This tool is designed using an Arduino UNO sensor, which can be connected to the sensor, and is made with 3D design with the help of Blender 4.1 software—the water flow sensor functions as a discharge meter. The LCD screen displays the results of the calculation of the discharge and water level in the venturi pipe. The tool has a guide sheet for programming procedures using WOKWI software. Based on the simulator results, the program code applied to the WOKWI simulator runs well with the Water Level Pump indicator ON/OFF. Media designs include Arduino, Resistor, Slides Witch, Arduino Atmega8, LED display, water pump, water pipe and venturi, DPDT relay, LED lamp, and ultrasonic distance measuring sensor. So, it can be concluded that the water flow or water level sensor program code and the continuity principles teaching aid design trials went well, so the implementation stage for high school level students can be carried out for further research.

Authors: Rahmat A D , Kuswanto H , Wilujeng I 
Published: December 2024

Abstract

Angklung, a traditional West Java musical instrument, has achieved global acclaim, elevating Indonesia’s cultural prestige. This study uses a qualitative phenomenological approach to explore how physics concepts are integrated into the craft of making Angklung. Data were collected through interviews, documentation, and observation and analyzed descriptively with triangulation techniques. The research reveals that the process of making Angklung involves traditional craftsmanship and significant physics concepts, such as resonance, sound frequency, and wave propagation. The method includes four main stages: bamboo selection, bamboo cutting, tuning, and assembly. Each stage illustrates relevant physics principles, providing insights into how bamboo properties affect acoustic characteristics and how precise carving and cutting techniques influence sound quality. The tuning stage further educates students about harmonizing sound through acoustic principles using tools like tuners. This study offers a novel perspective by integrating traditional Angklung craftsmanship with educational physics concepts, enriching cultural heritage and scientific understanding.

Published: December 2024

Abstract
This study aims to assess students’ scientific literacy skills on energy and simple machines. This quantitative descriptive research employed a survey method. It involved 63 ninth-grade students who had covered the material on energy and simple machines from three junior high schools in Malang, Indonesia. The research utilized an instrument consisting of 8 items from the Energy and Simple Machines Scientific Literacy Skills Test with a Cronbach’s Alpha value of 0.807 (very high). Data analysis employed descriptive statistics, followed by ranking classification based on sub-topics and each scientific literacy indicator. The results showed that students’ average scientific literacy skills were in the “not good” category. This was due to students not being accustomed to solving scientific literacy-indicated problems, which tend to contain long, complex readings requiring extra comprehension. Additionally, teacher involvement was lacking in applying methods, models, or learning strategies related to scientific literacy. When reviewed by each sub-topic and scientific literacy indicator, the energy sub-topic scored higher than the simple machines sub-topic, and the first indicator, explaining phenomena scientifically, scored the highest among the three indicators. Based on these findings, implementing project-based learning models that enhance students’ scientific literacy, such as STEAM elements, is highly recommended.
