Unipolar induction and relative rotation
Authors: Timofeev V. B. , Timofeeva T. E.
Published: January 2025

The recent failure of attempts to extract the rotational energy of the Earth by unipolar induction methods suggests a need for further research on unipolar induction. It is implied by the special relativity theory that the interaction of electric charge and magnet in unaccelerated motion depends only on the relative rate. The electromotive force of unipolar induction in a complete electrical circuit depends only on the relative rotation of the magnet and the connected through slide contacts voltmeter. To ascertain if the electric field resulting from the magnet’s rotation in an inertial frame of reference or in a frame of reference rotating in a magnetic field is the result of absolute or relative rotation, it is necessary to measure the field. For this purpose, the paper introduces the experiment with the relative rotation of a ring-shaped magnet and a cylindrical capacitor. The capacitor is permanently connected through sliding contacts to the electrostatic meter. The electrostatic meter detects the potential difference on the capacitor while the magnet or capacitor is being rotated. The measurements showed that the potential difference on the capacitor is depends not on the capacitor rotating in case of a stationary magnet or a magnet rotating while the capacitor is stationary. It is close to zero when the capacitor rotates with the magnet. According to the research results, the interaction of the electric charge and magnet in the nonrelativistic case depends on the relative rotation rate. This interaction is described by the Lorentz formula
On the Structure of “Numeral” Concept (as Exemplified by Chinese Language)
Authors: Bankova L. L.
Published: January 2025

Numbers are an important cognitive category in any culture of language thus attracting the research interest. This article depicts the author’s view of the structure of the concept of number and introduces the methods to explore it drawing on the example of the Chinese culture of language. The concept of number is a metaconcept. The concept under analysis comprises the core and the periphery and enjoys a layered structure. It consists of a collection of certain number-concepts (subconcepts) which are relevant for the culture of language at hand. The subconcepts go in layers. It is important that the quantity of number-concepts in any culture of language is limited. Therefore, the quantity of the layers in the concept of number also is limited. The numbers that are most relevant for the culture belong to the core of the concept, and the less relevant numbers pertain to the close and far periphery. Thus, the metaconcept of number is an arrangement of specific subconcepts. The study of the number metaconcept shall only be available through the study of each individual subconcept. A specific number-concept (subconcept) also contains a core and a periphery of its own. As opposed to a metaconcept, the core of a subconcept is represented by its notional elements and the periphery accommodates its figurative and axiological components. Such an approach correlates with the “from-the-objective-to-the-subjective” principle. In the Chinese culture of language the core of the number metaconcept includes such layers (subconcepts) as the concepts of numbers two, three, five, one, ten thousand. The periphery of the number metaconcept is represented by the subconcepts of the numbers pertaining to the first ten which are not included in the core as well as other seventeen layers. In the conclusion of the article the author draws parallels between the structures of the number concept and matter in the physical universe
Hemeronyms of the Yakut periodical press as onomastic realities (1930s, 1960s, 1990s)
Authors: Borisova N. M. , Nadkin V. B.
Published: January 2025

The topicality and significance of the research are substantiated by the fact that the hemeronyms of the Sakha language periodicals are characterised by stable changes. The novelty of the research consists of the first attempt in the Yakut press and journalism to comprehend and systematise the titles of regional newspapers and periodicals as independent units, considering the functional specificity of the titles in the communicative processes. Nevertheless, we suggest that titles have been overlooked due to their contradictory communicative status. In this article our purpose is to identify the specificity of the titles of Yakut newspapers and periodicals of the Stalinist System (1930-1959), the era of Stagnation (1960-1990) and the post-Soviet transformation (from 1991 to the present day). For this purpose, it is necessary to explain the following main tasks: to review the history of the Yakut periodical press from 1930 to the present period, to explain the relevance of the hemeronyms of Yakut periodicals to the socio-political, economic, sociocultural processes and to analyse the quantitative ratio of the hemeronyms. This research is based on the combination of historical-typological analysis with the main methods of onomastics as a branch of linguistics – structural, comparative and statistical. The use of key meanings and key words allows for a comparison of the evolution of periodical titles throughout history. Therefore, the title of the Sakha language periodical press evolved in the 1930s, 1960s, and 1990s. Basically, these years provided the hemeronyms of the periodical press in Yakutia specific onomastic realities. In these days, the regional periodicals have become available online due to the development of digital technologies, making it of great advantage for the inhabitants of the republic. In our opinion, the identification of specific features of regional periodicals is one of the bases on which the aspects of the research of media hemeronyms are based. Meanwhile, new challenges are bringing new approaches to the solution

Einsatz von Gamification zur Steigerung der Akzeptanz von digitalen Gesundheitsanwendungen (DiGA) - Ergebnisse einer qualitativen Studie
Authors: Malzahn Birte , Ulrich Lena
Published: January 2025

Digitale Gesundheitsanwendungen (DiGA) unterstützen u. a. die Therapie von Krankheiten oder Verletzungen und können unter bestimmten Bedingungen auf Rezept verordnet werden (Bundesinstitut für Arzneimittel und Medizinprodukte, 2023; Friesendorf & Lüttschwager, 2021). Für den Erfolg einer Therapie mittels DiGA ist jedoch eine beständig hohe Eigenmotivation der Patient*innen erforderlich. Der vorliegende Beitrag untersucht, welche Faktoren die Nutzerakzeptanz von DiGA beeinflussen, und insbesondere auch, welchen Einfluss Gamification in diesem Zusammenhang ausübt. Hierfür wurde ein theoretischer Bezugsrahmen aufgestellt, der mittels einer stichpunktbezogenen qualitativen Datenerhebung überprüft wurde. Die Ergebnisse zeigen, dass u. a. die wahrgenommene Nützlichkeit einen Einfluss auf die Nutzungsabsicht ausübt. Gamification erhöht zwar den Spaß an der Nutzung, dieser übt aber keinen starken Einfluss auf die Absicht zur Nutzung der untersuchten DiGA aus. Der Beitrag zeigt mögliche Konsequenzen der Ergebnisse für Forschung und Praxis auf.
Model Generalisation for Predicting the Amount of Photosynthetically Available Radiation in the Water Column from Freefall Profiler Observations
Authors: Tholen Christoph , Nolle Lars , Wollschläger Jochen , Stahl Frederic
Published: January 2025

In modern oceanography Photosynthetically Available Radiation (PAR) is used for modelling vegetation growth as it is a requirement for the process of photosynthesis. PAR as integrated value of the light spectrum between 400-700 nm can be measured directly using respective sensor systems. However, PAR can also be determined indirectly using measurements from only a small number of discrete wavelengths. In this paper, such a modelling approach is presented for predicting PAR in the water column. The approach uses spectral information within the water column and from above the sea surface. Three different modelling approaches based on artificial intelligence (AI) were used. It was shown that the artificial neural network (ANN) approach outperformed the regression tree (RT) and the linear regression (LR) approaches. It was also shown that the models generalise well, with an accuracy loss of 10 % based on the median, on data recorded in other geolocations without additional modification or re-training.

Published: January 2025

This article conducts a comprehensive correlation analysis to explore the relationship between the development volume by developers and average market prices in Poland's housing sector from 2010 to 2023, utilizing quarterly data on the number of apartments released and their average prices. It employs both linear and nonlinear correlation analysis alongside wavelet coherence analysis. Preliminary correlational analysis offered insights into the basic interdependency patterns, highlighting how developer-supplied apartment numbers impact average prices. Wavelet coherence analysis, a more sophisticated approach, decomposed the data across various frequencies to uncover complex, nonlinear relationship patterns potentially missed by conventional correlation methods. The findings of the study highlight significant connections between the variables that vary over time and space, emphasizing the complexity of the housing market and underscoring the necessity for thorough analysis. These results carry important implications for developers, investors, and housing policy formulation, contributing significantly to understanding Poland's residential real estate market dynamics and supporting further research and strategic real estate industry planning.
Catalytic allylation of native hexoses and pentoses in water with indium
Authors: Adak Tapas , Menard Travis , Albritton Matthew , Florit Federico , Burke Martin , Jensen Klavs , Denmark Scott
Published: January 2025

Carbohydrates are an abundant, inexpensive, and renewable biomass feedstock that could be a cornerstone for sustainable chemical manufacturing, but scalable and environmentally friendly methods that leverage these feedstocks are lacking. For example, 1-allyl sorbitol is the foundational building block for the polypropylene (PP) clarifying agent Millad® NX® 8000 which is produced on multi-ton scale annually, but the current manufacturing process requires superstoichiometric amounts of tin. , The NX 8000 additives dominate about 80% of the global clarified PP market, used in concentrations of 0.01% to 1% during PP production to improve its transparency and resistance to high temperatures, which translates to 300-30,000 tons annually. The market volume of PP in 2022 was approximately 79.01 million metric tons (MMT), with demand expected to rise by nearly 33% to 105 MMT by 2030. The cost and sustainability benefits of clarified PP are driving this demand, necessitating more clarifying agents. Herein, we report a high-yielding allylation of unprotected carbohydrates in water using a catalytic amount of indium metal and either allylboronic acid or the pinacol ester (allylBpin) as donors. Aldohexoses, aminohexoses, ketohexoses, and aldopentoses are all allylated in high yield under mild conditions, and the indium metal is recoverable and reusable with no loss of catalytic activity. Leveraging these features, this process was translated to a scalable continuous synthesis of 1-allyl sorbitol in flow with high yield and productivity through Bayesian optimization of reaction parameters.

Essays on Risk Experience, Perception, and Adaptation/Mitigation Strategies
Authors:   , Nguyen Mui
Published: January 2025

This thesis includes three essays that examine risk experience, perception, and adaptation/mitigation strategies, which are vital for effective responses to climate change and natural hazards. Chapter 2 investigates how New Zealand farmers perceive future drought risks and how these perceptions influence their climate mitigation and adaptation actions. The data comes from the 2019 Survey of Rural Decision Makers and district-level daily drought data— the New Zealand Drought Index (NZDI) for 2009 and 2018. The findings indicate that droughts have impacted all regions of New Zealand over the past 14 years, particularly the Waikato region in the North Island. Farmers generally expect droughts to become more frequent and intense by 2050, with over 90% believing this will affect their farms. The study highlights age, gender, and education as significant factors shaping these perceptions, with older, college- educated, and female farmers expressing greater concern about future drought risks. Chapter 3 shifts the focus to central Vietnam, asking similar questions. Using panel household data from five waves between 2008 and 2017, combined with monthly high-resolution precipitation and temperature data, the study employs the Standardized Precipitation-Evapotranspiration Index (SPEI) to describe drought events at the sub-district level. As in New Zealand, most individuals expect an increase in future drought occurrence. Households prioritize agricultural and environmental actions, focusing on irrigation and infrastructure management. More frequent past drought experiences lead to an increased perception of future drought risk and the adoption of prevention/mitigation strategies. Chapter 4 examines the impacts of the Canterbury earthquake sequence (CES) of 2010-2012 on individual subjective well-being, focusing on life satisfaction, general health, income adequacy, and safety. Using data from the New Zealand General Social Survey and a difference-in-difference-in-difference (DDD) approach, the study matches this data with residential insurance data from the public insurer to identify the most CES-affected areas, investigating earthquake impacts at a micro-level. The findings reveal significant effects on various well-being aspects, with a consistent decrease in life satisfaction in earthquake-affected areas. Specifically, narrowly defined areas, such as severely impacted meshblocks in Christchurch City (CHC), experienced widespread negative effects across all well-being indicators.

A comparative analysis of understanding and errors in inverse functions among Korean and Chinese high school students
Authors:   The Korean School Mathematics Society, Cho Cheong Soo
Published: January 2025

The inverse function is a reverse function of a given function and is an important mathematical topic where students can acquire reversible reasoning. In reviewing various previous studies, it was found that the understanding of inverse functions has been investigated from various perspectives among high school students, college students, and prospective mathematics teachers. However, there has been no study that compares and analyzes the understanding of inverse functions among high school students on an international scale. Therefore, this study compared and analyzed the level of understanding, proficiency, and types of errors related to inverse functions among 209 high school students from Korea (162 students) and China (47 stu dents) using a questionnaire task that involved finding the inverse functions and graphing six types of functions (linear functions, quadratic functions, rational functions, radical functions, exponential functions, and logarithmic functions). From the results of this study, the rate of non-response among Korean students in finding the inverse function of a given function exceeded half, while there were no non-responses from Chinese students. “Students from both countries did not use line symmetry to graph the inverse functions and showed no connection between the inverse function expressions and their graphs.
Analysis of mathematical performance and reasoning process of generative AI: focusing on the college scholastic ability test
Authors:   The Korean School Mathematics Society, Kwon Oh Nam , Shin Byoung Chul , Oh Se Jun
Published: January 2025

This study analyzes the mathematical performance and reasoning processes of the generative AI model o1-preview to explore its potential application in mathematics education. In particular, this research uniquely delves into the reasoning processes of generative AI, identifying specific stages and characteristics that emerge during problem-solving. Using math problems from the Korean College Scholastic Ability Test (2022-2024), the study examined the model's response accuracy and the characteristics of its reasoning steps. The findings reveal that o1-preview demonstrated high accuracy in 2-point and 3-point questions and successfully solved some challenging 4-point questions. During the reasoning process, the model predominantly derived correct answers through the ‘analysis’ and ‘planning/execution’ stages, with particularly high accuracy observed when the ‘exploration’ and ‘verification’ stages were included. This study suggests that o1-preview could serve as a valuable computational tool in mathematics education, highlighting its potential for practical application. However, the study also identified limitations in the model's performance, particularly when ‘exploration’ and ‘verification’ stages were insufficiently executed. To address these issues, the importance of teacher guidance and well-designed prompts for utilizing generative AI in problem-solving is emphasized. This research evaluates the practical applicability of generative AI in real educational settings and aims to explore effective usage strategies for diverse educational environments in the future.

Diabetes mellitus is a prevalent metabolic disorder that still remains a threat to public health all over the world. Oxidative stress is a critical factor in the pathogenesis and progression of diabetes mellitus and its associated complications. Plants contain many antioxidant compounds that can provide protection against free radical-related diseases. The present study aims to evaluate the potential of ethanol extract of Pemphis acidula leaves as antidiabetic agent by measuring its total phenolics and flavonoids content, and its antioxidant and α-amylase inhibitor activity as well. The total phenols content was determined using Follin-Ciocalteu method and total flavonoids content was determined using the AlCl3 colorimetric method, while in vitro antioxidant activity was evaluated using DPPH method. Results of the study showed that ethanol extract of Pemphis acidula leaves contains total phenolics and total flavonoids equivalent to 5390mg GAE/100 grams of extract and 581.66mg QE/100 grams of extract respectively, and it had also been proven that the extract has strong antioxidant and α-amylase inhibitor activity with IC50 of 57.71 ppm and IC50 of 70.05 ppm respectively. From these results, it can be concluded that ethanol extract of Pemphis acidula leaves has the potential as an anti-diabetic agent.
Flexibility vs Harmonization: Analysing the Environmental Regulations and Global Supply Chains
Authors: Chandra Simran
Published: January 2025

The regulatory standards of the environment define how to overcome the physical and organizational links in the complex global supply chain. These restraints on environmental quality, which is the primary concern of the responsible nations, differ widely among them. This mismatch needs a delicate balance between two opposing ideologies: homogeneity and conformity. Harmonization provides a base of unified rules for all the countries, and flexibility becomes an option with the possibility to modify the rules according to governments’ demands. This project explores the real-world practical complexities and promising prospects associated with regulations harmonization and elasticity; moreover, it presents their massive role in the foreign supply chain. We will pursue a deliberate analysis of how they would constitute impediments to operational efficiency and competent business activities. Furthermore, we shall find out if cooperating internationally regarding unifying environmental standards is worth it and if it brings any related benefits.Moreover, the study will investigate the role played by private government measures in dealing with tricky environmental regulation challenges. Such programs often function as channels that ease regulatory cross-fertilization, which is a basis for uniform business compliance and sustainability across other markets worldwide—this article endeavors to bring novel insight into the intricate interconnections between natural law and world trade. Looking at complications and solutions, we would love to suggest measures for implementing an inclusive approach, both of which are saving the environment and preserving the vibrancy of the global supply chain.
Case Law Analysis: McBoyle v. United States 283 U.S. 25 (1931)
Authors: Chandra Simran
Published: January 2025

The ‘McBoyle v. United States’ case from 1931 is regarded as a formative ruling. It highlights the significance of following the ‘plain sense of legislative language’ and avoiding undue broad interpretations that can have unexpected implications. ‘The National Motor Vehicle Theft Act’ forbids the interstate transfer of stolen vehicles, and the core issue in the case was, whether an aircraft might be classified as a “motor vehicle” under the aforementioned statute.
Transtension in the Levant Basin: Challenging the Syrian Arc model

Published: January 2025

Late Cretaceous intra-plate shortening, and inversion of the Permian to Jurassic rift system, resulted in the ~1000 km-long, S-shaped Syrian Arc Fold Belt which dominates the Levant regional topography through Egypt, Israel, Lebanon, and Syria. Subsequent Miocene folding along the same trends of the Late Cretaceous fold belt, was likely associated with the collision of Arabia and Eurasia. The kinematic model detailing how the Miocene collision initiated the observed inversion is currently unclear yet is essential to our understanding of the geological development of this tectonically complex region. We here present a borehole-constrained seismic-stratigraphic interpretation of 3D seismic reflection data from the Levant Basin that provides unparalleled imaging of these Oligocene-Miocene folds. We show that one of the structures, the NE-SW trending Tamar Anticline, formed during the Burdigalian (lower-Miocene) with no indication of a precursor phase of Late Cretaceous inversion, as previously suggested. We show how the Tamar Anticline was formed concurrent to movement on adjacent strike-slip faults and to the dissection of the anticline by NW-SE-striking normal faults. Simultaneous NW-SE-directed shortening and NE-SW-extension, related to motion along ~E-W strike-slip faults suggests the Tamar Anticline and similar structures developed during the Miocene folding phase formed due to transtension, driven by the opening of the Red-Sea. This new geodynamic model highlights that Late Cretaceous and Miocene folding associated with the Syrian Arc Fold Belt may be geometrically comparable, but stem from different geodynamic regimes.

The Effect of Taboo Food, FE Tablet Consumption and Tea Caffeine on Hemoglobin Levels in Pregnant Women
Authors: Akbarini Oon Fatonah , Pramuwidya Asmaurika , Lamana Aspia
Published: January 2025

Pregnancy anemia is a body condition with a hemoglobin level in the blood of <11 gr% in the 1st and 3rd trimesters or a hemoglobin level of <10.5% in the 2nd trimester. The incidence of anemia in pregnant women in the Antibar Community Health Center area, East Mempawah District, was 61 people in 2021. Anemia in pregnant women has impacts such as abortion, bleeding during pregnancy, premature birth, fetal disorders, labor process disorders, postpartum disorders, congenital defects, LBW, perinatal death and others. Based on preliminary results, there are still pregnant women who implement food taboos during their pregnancy. The level of compliance with iron tablet consumption among pregnant women in West Kalimantan Province is 82.50%). Currently, people in Mempawah Regency still have a culture of drinking tea in their daily lives, including pregnant women. The aim of this research is to analyze the effect of food taboo, consumption of fe tablets and tea caffeine on hemoglobin levels. This type of research is a quantitative study, with a cross sectional design. The population is all pregnant women, the sample for this study was 40 pregnant women. Data analysis used the Chi suare statistical test. The statistical test results show a p-value of 0.937, meaning there is no relationship between food taboo and hemoglobin levels, there is a relationship between consumption of Fe tablets and hemoglobin levels with a p-value of 0.021 and there is a relationship between the habit of drinking tea and hemoglobin levels with a p-value of 0.04. From these results, it is very important for pregnant women to pay more attention to their consumption patterns of drinking tea and Fe tablets so that there is no decrease in hemoglobin during pregnancy..
