Abstract
This study employed the finite element method to investigate the biaxial stretching deformation mechanism of polyamide 6 (PA6) Film. First, the PA6 film was subjected to biaxial stretching experiments under various conditions. Then, a three-dimensional finite element model of PA6 film was established. The biaxial stretching experiments of PA6 films under various conditions were simulated by the established finite element model. The results show that the biaxial stretching of the films under various conditions exhibited a transition from elastic deformation to plastic deformation. Meanwhile, as the stretching ratio increases, the more uniform stress and strain distribution on the film surface can be found in the stress and strain contour diagrams. The stress and strain distributions were found to be largely consistent under various annealing temperatures. However, lower stretching rates resulted in higher internal stress intensity, making the films more resistant to biaxial stretching. The findings of this study provide a theoretical reference for a deeper understanding of the deformation mechanisms of PA6 films during the biaxial stretching process.

Abstract
In late 2020, laurel wilt impacted the avocado collection at the United States Department of Agriculture, Agricultural Research Service, National Clonal Germplasm Repository, Subtropical Horticulture Research Station in Miami, Florida. Monitoring of the ambrosia beetle (Coleoptera: Curculionidae) community over the next 18 months suggested that the primary vector, Xyleborus glabratus Eichhoff, was likely not responsible for spreading the fungal pathogen (Harringtonia lauricola [T.C. Harr., Fraerich & Aghayeva] Z.W. de Beer & M. Procter; Ophiostomatales). Rather, eight secondary vectors were detected in greater numbers, with Xyleborinus saxesenii (Ratzeburg) being the most abundant. After detection of laurel wilt, beetle numbers increased for 2–4 months, then gradually declined over the next year. This pest suppression was likely due to several countermeasures, including the prompt removal of infected trees and prophylactic macroinfusions with propiconazole fungicides. In addition, to preserve the genetic diversity of the Miami avocado germplasm, the Subtropical Horticulture Research Station is collaborating with other Agricultural Research Service facilities to establish backup collections at alternative locations free of the laurel wilt pathogen and its beetle vectors.
Multiaxial creep deformation investigation of miniature cruciform specimen for type 304 stainless steel at 923 K using non-contact displacement-measuring method
Authors: Hiyoshi Noritake 
Published: October 2024

Abstract
Multiaxial creep investigations at high temperatures are required to guarantee the integrity of structural materials such as boiler pipes for power generation and turbine blades for aviation and industrial applications. The multiaxial creep testing method using a cruciform specimen has several advantages, and the authors successfully downsized the specimen. The authors also developed a technique for the in situ observation of the specimen in an electric furnace and the non-contact displacement measurement in the development of a biaxial tensile creep testing machine for the miniature cruciform specimen. By observing the specimen at a target mark during the creep testing through an observation window installed at the bottom of the furnace, it was possible to visualize the specimen surface variations and obtain the axial strain from the locus of the target marks. The Mises-type equivalent strain was calculated from the axial strains obtained in the equi-biaxial tensile multiaxial creep testing and was compared with the strains obtained in the uniaxial creep testing. The Mises-type equivalent strain can be expressed using a unified method up to approximately 5% of the initial strain in the test, even in the multiaxial stress state.
One-pot fabrication of open-spherical shapes based on the decoration of copper sulfide/poly-O-amino benzenethiol on copper oxide as a promising photocathode for hydrogen generation from the natural source of Red Sea water
Authors: Alnuwaiser Maha Abdallah , Rabia Mohamed 
Published: October 2024

Abstract
Harnessing green hydrogen production from natural Red Sea water offers an innovative solution to address energy challenges. A one-pot fabrication method is used to create novel nanocomposite thin films with open-spherical shapes, utilizing copper sulfide/poly-O-amino benzenethiol decorated on copper oxide as a promising photocathode. After thorough analysis, a unique morphology characterized by open spherical shapes is projected, which contributes to improved optical absorption. The bandgap of the nanocomposite is 1.17 eV, enabling efficient absorption of light across the entire optical spectrum, extending up to 950 nm. Utilizing Red Sea water as an electrolyte, the generated J
ph serves as an indicator of H2 gas production. The substantial J
ph value of −0.82 mA cm−2 is achieved at −0.85 V under light illumination. Furthermore, J
ph values exhibit variability, starting at −0.58 mA cm−2 (at 730 nm) and increasing to −0.75 mA cm−2 at a wavelength of 340 nm. The estimated hydrogen gas production rate reaches 1.5 µmole h−1 cm−2, translating to an impressive 15 µmole h−1 for every 10 cm². This remarkable rate underscores the effectiveness of the photocathode, especially given its fabrication through a single-step process that is suitable for mass production. In addition, its cost-effectiveness further enhances its appeal as a viable solution for renewable energy production for hydrogen gas generation from seawater.

Показана перспективность совместного обжига труднообогатимых окисленных и сульфидных свинцово-цинковых руд Озерного месторождения на стадии подготовки сырья к флотации. При совместном обжиге окисленной свинцово-цинковой руды с сульфидной рудой при 650 - 700 °С происходит селективное окисление пирита с образованием серосодержащих агентов и сульфидирование труднообогатимых окисленных минералов свинца и цинка. Экспериментально доказано, что селективное окисление пирита сопровождается дезинтеграцией по межфазным границам сульфидных минералов свинца и цинка. Основными продуктами взаимодействий являются ZnS, PbS, Fe3O4, Fe2O3, что значительно облегчит дальнейшее флотационное обогащение. Использование предлагаемого способа переработки полиметаллических руд позволит вовлечь в производство не только окисленные свинцово-цинковые руды, но и труднообогатимые сульфидные, увеличить срок работы горнодобывающего предприятия и снизить техногенную нагрузку на окружающую среду. Образцы охарактеризованы методами рентгенофазового анализа, дифференциальной сканирующей калориметрии, оптической микроскопии, химического анализа и методом Ритвельда с использованием программы TOPAS.
The article proves the promising nature of joint roasting of rebellious oxidized and sulfide lead-and-zinc ore from Ozerny deposit at the stage of ore preparation for flotation. The joint roasting of lead-and-zinc ore and sulfide ore initiates generation of sulfur-containing agents and sulfidation of rebellious oxidized lead and zinc. It is experimentally proved that selective oxidation of pyrite proceeds together with disintegration of lead and zinc along the interphase boundaries. The main products of such interaction are ZnS, PbS, Fe3O4 and Fe2O3, which can greatly facilitate flotation later on. This method of complex ore processing can potentiate commercialization of oxidized lead-and-zinc ore and rebellious sulfide ore, can prolong service life of mines and mitigate the environmental impact of the industry. The produced samples are analyzed and described using the X-ray phase analysis, differential scanning calorimetry, optical microscopy, chemical analysis, Rietveld refinement and program TOPAS.

Published: October 2024

Проведена серия лабораторных экспериментов по циклическому деформированию сыпучей среды на приборе однородного сдвига. Стационарные краевые условия в течение сотен тысяч циклов сдвига приводят к нестационарной реакции среды. В среде наблюдаются периоды колебаний напряжений порядка десятков, сотен и тысяч циклов. Причина нестационарной реакции среды связана с периодическим формированием и разрушением системы кластеров и силовых цепочек. С использованием метода дискретных элементов выполнено численное моделирование циклического сдвига сыпучей среды по аналогичной программе нагружения, которое показало адекватность применения указанного численного метода и соответствие полученных результатов данным лабораторных экспериментов.
The authors implemented a series of lab-scale cyclic shear deformation tests of granular medium. The steady-state boundary conditions kept for the hundreds of thousands shear cycles result in the time-varying response of the test medium. The periods of stress fluctuations of the order of tens, hundreds and thousands cycles are observed in the medium. The time-varying response of the medium is connected with periodic formation and deformation of clusters and force chains in the medium. The DEM-based numerical modeling of cyclic shear of a granular medium with the same loading program as in the tests shows the adequacy of the discrete element method and the agreement of the numerical and experimental data.

The Image and Appearance of a Citizen as Objects of Civil Rights: The Relationship of Concepts
Authors: Ivanov Andrey 
Published: October 2024

Introduction: the scientific paper solves the problem of the correlation of categories of appearance and image of a citizen as objects of civil rights. The author has established the interrelation and interdependence of the appearance and image of a citizen, as well as the identity and features of these intangible benefits, which are objects of relevant personal non-property rights, allowing solving the problem of establishing the legal regime of these objects. The analysis of the positions of representatives of the scientific community on the assessment of the independent legal nature of the image of a citizen in the context of its relationship with the appearance is carried out. It is stated that there is no unified approach to assessing the relationship between the right to image and the right to appearance; there is no unified approach to determining the object mediating these personal non-property rights. The purpose of the work is to solve the problem of the correlation of the legal categories of appearance and image as objects of civil rights by identifying the criteria for their differentiation, substantiating their independent nature based on the established features. Methods: the purpose of the study has determined the use of the dialectical method of scientific cognition in the analysis of the problem of interest, in its entirety using the methods of analysis and synthesis. Results: based on the studied scientific positions, as well as the provisions of the legislation, the different legal nature of the categories of appearance and image as objects of civil rights is established. The criteria allowing distinguishing the specified objects are revealed. The results of the study will serve as a basis for further doctrinal research of these related phenomena of private law science. Conclusions: based on the revealed differences, it is justified that appearance and image are different objects of civil rights. The citizen’s right to the inviolability of the image and the right to appearance are not in a relationship of subordination, and one right does not condition the other, and these rights have an independent legal nature from each other, which is expressed in the special objects of legal protection, the specifics of the focus of protection of these rights and various legal regimes for the protection of these rights. The concept of the image of a citizen as an object of civil rights is formulated.
Problems and Prospects of Unification of the Concepts of “Tokens”, “Digital Assets” and “Digital Rights”
Authors: Kostyan Oksana 
Published: October 2024

Introduction: the accelerated digital transformation of the economy leads to a lack of unity in understanding the essence of new digital objects and a lag in the legal regulation from the pace of digitalization. As a result, when characterizing new digital objects, there arise terminological inaccuracies, discussions regarding the expediency and correctness of legislative innovations, and the gaps in the legal regulation of digital objects of legal relations. As a result, the purpose of the current study is to define the essence and delineate the concepts of “token”, “digital assets” and “digital rights”. To achieve this goal, the following tasks are defined: to study the definitions of the above-mentioned concepts available in the legal doctrine, their role in the civil legislation, to develop a systematic understanding of the digital objects selected for research. Methods: the methodological framework for the study is a set of methods: the terminological analysis of individual digital objects – tokens, digital assets and digital rights; the generalization of the studied materials by induction to determine the subordination of the described digital objects; the generalization and comparison of doctrinal concepts on the relationship between the concepts of “digital assets” and “digital rights”. Based on the conducted research, the following results are achieved: the doctrinal differences are revealed in the understanding of the term “token”, in the correctness of the identification of “digital rights” as an object of civil rights, in the correlation of the concepts of “token”, “digital asset” and “digital rights”; the classification of digital assets is of scientific interest in the framework of further research. According to the results of the scientific research, the author has made a number of conclusions, in particular: 1) the lack of unity in the definitions of new digital terms generates discussions regarding the current norms of the Russian legislation and hinders the introduction of promising digital structures into civil circulation; 2) in order to unify digital terminology, the following changes to the Russian legislation are proposed: digital assets should be distinguished as a separate category of objects of civil rights; digital rights should be defined as a kind of digital asset expressed in monetary form; a token should be defined as a means of balance sheet accounting of a digital asset and the authentication of users of an information system.

Published: October 2024

Self-medication with antibiotics among college students is a growing concern due to its potential adverse effect and emergence of antibiotic resistance. This study was aimed to investigate the prevalence, reasons, and associated factors of self-medication with antibiotics among college students in Dakshin Kannada. Understanding the extent of self-medication practices and underlying motivations can inform targeted interventions to promote responsible antibiotic use and mitigate the risks associated with inappropriate antibiotic use.A cross-sectional survey was conducted among college students to assess self-medication practices with antibiotics. A structured questionnaire was administered to collect data on demographic characteristics, self-medication behaviour, reasons for self-medication, sources of antibiotics, knowledge and awareness of antibiotic use, and healthcare-seeking behaviour. The data were analysed.Demographic analysis revealed a predominantly young population, with 67.4% of respondents admitting to practicing self-medication with antibiotics. Convenience, cost-saving, and previous successful experiences with antibiotics were identified as primary motivations for self-medication. Antibiotics were often obtained from leftoverprescriptions or through informal channels like friends or family members. Awareness of the risks associated with self-medication was relatively low, but a significant proportion of students sought professional medical advice afterward, particularly in cases of persistent or worsening symptoms.The study highlights the widespread practice of self-medication with antibiotics among college students, driven by factors such as convenience and cost-saving. Efforts to improve education and awareness on self-medication of antibiotic are warranted to promote responsible antibiotic use and mitigate the emergence of antibiotic resistance.

Published: October 2024

This study aimed to investigate the effects of social networking sites (SNS) on strengthening self-protective behaviors after COVID-19 to prevent post-COVID-19 conditions in the working-age population in Thailand. Data were collected through a cross-sectional online survey of 400 working-aged Thais. Multiple regression analysis (MRA) was employed to analyze the data at a 0.05 significance level. The findings revealed that YouTube (beta = .275) and Facebook (beta = .182) positively impact self-protective behaviors while Twitter (beta = .237), Facebook (beta = .198) and Tiktok (beta = .119) influence attitudes towards these behaviors. Additionally, Twitter (beta = .206) and LINE (beta = .145) affect subjective norms. YouTube (beta = .288) and LINE (beta = .165) significantly enhance self-efficacy. This study contributes to the broader understanding of how social networking sites can reinforce self-protective behaviors against long COVID-19 among the working-age population. This study contributes valuable insights into the role of social networking sites in promoting health behaviors after COVID-19. The findings offer practical implications for health communication planning by expanding knowledge on the effectiveness of these platforms. Policymakers, social marketers and health organizations can leverage these insights to design targeted interventions to reduce the risk of COVID-19 and prevent future COVID-19 outbreaks at both national and international levels.
