The theoretical foundations of the recovery process and the technology of silicon smelting in electric arc furnaces are considered. The results of a study of thermodynamics, reaction kinetics, and mechanisms of the melting process are presented. Production issues are covered: charge preparation, smelting, refining, gas purification. Physicochemical models of the carbothermal process were developed, proposed and tested under industrial conditions (Tau-Ken-Temir LLP), which made it possible to assess the influence of the specified technological parameters of the smelting (chemical composition and loading coefficients of charge components, temperature) on silicon recovery and grade. To obtain the base material, metallurgical grade silicon is used, obtained by melting in ore-thermal furnaces (RTP). In this regard, the research goal is determined, which consists in studying ways to improve the quality (chemical purity) of silicon, and methods for achieving it at this stage of the study - modeling the carbothermal process for producing silicon.The article describes the main mechanism for the recovery of silica in the furnace, presents one of the designs of the furnace and the technological scheme for the production of silicon. The author suggested studying the process of producing metallurgical silicon in RTP using the HSC Chemistry software package. A model of silicon smelting in RTP was formed, which adequately describes the technological process for producing metallurgical silicon.

Published: October 2024

This article describes a method for extinguishing fires of oil and petroleum products in vertical steel tanks by feeding foam to form a low-layer film directly into the fuel layer at the bottom of the tank. The problems of extinguishing fires in tanks with a floating roof or on a pontoon when extinguishing fires in a storey way are briefly described. The main problems: contamination of the foam with oil and petroleum products, the time of lifting the foam to the surface of the tank, the appearance of “pockets” inaccessible for extinguishing, etc. The results of studies of the main modern systems for ensuring fire safety of oil and gas industry facilities, such as: transportation, processing and storage, are shown. The results of the study of the fire extinguishing process with film-forming foam in tanks, as well as the study of the properties of fluorosynthetic foams, are described. Examples of combined fire safety systems on pontoon tanks are also given.
A new approach to solving the problems of increasing the efficiency of geothermal field development
Authors: Mendebaev T.N.
Published: October 2024

The initial prerequisites for the effective development of geothermal deposits have been developed. Geological – reliable information about the geological structure of thermal water deposits, compositions, physical and mechanical properties of rocks in the “water-rock” system. Technical – means of well construction, design features and technological capabilities corresponding to the conditions of the mining environment, ensuring the production of highly informative geological material in the form of a core, maintaining the stability of the walls of wells from collapse and shedding. A series of diamond drill bits with a hydrojet effect of rock destruction, corresponding to the conditions of opening hot springs, have been developed and tested in practice for drilling wells. A scheme of a circulation system for the opening and development of geothermal deposits consisting of a vertically injection and an obliquely ascending well connected by a smooth bend of an intermediate shaft is proposed. The ideological novelty of the scheme, which differs from all known schemes for the development of geothermal deposits in the world, provides for the possibility of creating conditions for the manifestation of the internal energy of the earth’s interior and the thermal horizon, aimed at improving the efficiency of the development of geothermal deposits. The structural features of the scheme are that a vertical injection well lined with a filter column in the section of the thermal horizon is made with ledges, where shock waves of increased and decreased pressure are generated when water is supplied, by dividing the water flow into a central core and lateral components. As a result, the thermal horizon is affected by alternating hydraulic impulses, an increase in rock permeability and an acceleration of water inflow into the well. At the same time, by linking the borehole system with an intermediate trunk, and laying an ascending well with an obliquely cased filter column, the volume coverage of the thermal horizon is provided, increasing the uninterrupted operation period, where the circulation channel from the lower ledge to the entrance to the tank with smoothly bending joints is made with one diameter. This eliminates local pressure losses. By grinding the wall of the intermediate shaft with rock hardening, water leaks and pressure losses along the length of the circulation channel are eliminated. The significance of the circulation scheme – the extraction of hot water is carried out by forced self-discharge, without attracting energy from outside.

This paper presents the results of research on obtaining biochar from agricultural plant waste such as rice husk and straw. The selection of the optimal conditions for thermolysis, such as the duration and temperature of the process, has been conducted. The thermolysis products are characterized for iodine adsorption activity, cumulative water pore volume, and for bulk density. The porous structure of the obtained products has been studied by scanning electron microscopy. Based on the results of the research conducted, it has been found that biochars obtained from husk and straw with a thermolysis duration of 30 minutes have low iodine sorption characteristics and water pore volumes. With an increase in the duration of thermolysis, the sorption characteristics improve, the optimal for the husk is the thermolysis duration of 60 minutes at a temperature of 500°C, and for straw, the optimal thermolysis duration is 60 minutes at a temperature of 300°C. The best option is biochar obtained from rice straw at a duration of 60 minutes and a thermolysis temperature of 300°C, having an iodine adsorption activity of 54.61%, a cumulative water pore volume of 0.941 cm3 /g and a bulk density of 169.29 g/dm3. The obtained biochars from rice husk and straw have been studied by scanning electron microscopy at 4300 and 5000 times magnification, and they have a developed porous structure.

A borreliose de Lyme, também chamada de doença de Lyme (DL), é uma enfermidade infecciosa causada por bactérias do gênero Borrelia spp., transmitida por carrapatos do gênero Ixodes. Originou-se de um surto observado em 1975 em Old Lyme, Connecticut. O agente etiológico, Borrelia burgdorferi, foi identificado por Willy Burgdorfer em 1981. No Brasil, é conhecida como Síndrome de Baggio-Yoshinari (SBY), diferenciando-se da DL do Hemisfério Norte. A Borrelia burgdorferi no Brasil possui características morfológicas atípicas. A transmissão ocorre principalmente por carrapatos Amblyomma sp., Rhipicephalus sp. e Dermacentor sp. Roedores, cervídeos, aves migratórias e outros mamíferos são reservatórios. Os sinais clínicos variam, mas frequentemente incluem febre, artrite e manifestações neurológicas. A prevenção envolve evitar áreas infestadas e o uso de repelentes. No Paraná, estudos revelaram a presença de Borrelia burgdorferi em carrapatos e anticorpos em cães errantes e humanos em áreas rurais, evidenciando a necessidade de pesquisas regionais para entender a epidemiologia da doença no Estado.
Exploring value propositions and service innovation: the outsourcing of the National School Feeding Program
Authors: Silva Eliane Alves da , Silva Tania Nunes da , Pedrozo Eugenio Avila
Published: October 2024

The National School Feeding Program, knowing as PNAE, is a public policy responsible for providing meals to students in Brazil. This program exists since 1940s and was created to combating child malnutrition. The program evolved over the years until the passing, on 16 June 2009, of Act 11,947, which establishes that at least 30% of food purchases for school meals must come from family farmers. In this context, there is a perception that outsourced management does not aim to encourage local agriculture, and consequently the use of fresh foods in school meals, which is recommended by Act 11,947. Therefore, the purpose of this article is to describe the forms of value co-creation in the PNAE outsourcing process in two cities that meet the requirements of Act 11,947. Then, a qualitative-descriptive study and abductive logic were chosen, using, as a strategy, a multiple-case study in the cities of Aracaju and Taubaté. The implementation of the PNAE by the municipality depends on the multiple influences and interventions, such as institutional values and relationships between stakeholders. Based on the understanding of this dynamic, the practices of the stakeholders involved in the management of the PNAE begin to organize a value proposition according to the students’ needs, promoting meaning and structure for its recipients. There are different ways to practice outsourcing in this program. So, these different possibilities make a study on this topic relevant, as it highlights that the positive results of outsourcing depend on the implementation of a well-planned project. Thus, use co-creation value, originally from Marketing Research, in public policy can bring new perspectives of analyses.

Published: October 2024

Diversas correntes de pensamento surgiram quando intelectuais oriundos de colônias subordinadas ao imperialismo europeu começaram a buscar respostas nativas, ou seja, a partir dos atravessamentos simbólicos impostos pelo “homem branco” eurocêntrico, paternalista e capitalista, visando reinterpretar a narrativa dos acontecimentos. Nesse contexto, emergiram denominações como as Epistemologias do Sul, o pós-colonialismo e a descolonialidade, que compartilham um conjunto de ideias para interpretar essa realidade. No entanto, é comum que, nos estudos acadêmicos, essas três perspectivas sejam tratadas como se fossem equivalentes. Contudo, é importante destacar que, embora apresentem elementos epistêmicos semelhantes, elas não são sinônimas e, em vários aspectos, divergem significativamente. Este artigo tem como objetivo preencher uma lacuna nas pesquisas acadêmicas, tensionando as afinidades e divergências entre essas abordagens, com base central no pensamento de Boaventura de Sousa Santos e outros autores que exploram o tema. Metodologicamente, a pesquisa segue uma abordagem qualitativa (Minayo, 2016), descritiva e bibliográfica (Gil, 1999), e é compreensiva (Weber, 2019), pois busca entender as particularidades de cada uma dessas perspectivas. Ao realizar essa análise imersiva, conclui-se que, embora compartilhem críticas ao eurocentrismo e ao colonialismo, cada uma aborda essas questões a partir de enfoques distintos. Compreender suas especificidades permite uma análise mais precisa das formas de resistência ao imperialismo, das dinâmicas de poder globais e das propostas de transformação social. Além disso, evita a simplificação dessas correntes, valorizando suas contribuições únicas para os estudos acadêmicos e para a práxis política.

Published: October 2024

This researh examines the relationship between swimming proficiency and self-reported mental health outcomes in Chinese adults, considering different demographic variables. A descriptive-correlational research technique was used to recruit a varied sample from various areas and backgrounds in China. Systematic surveys evaluated swimming proficiency in multiple aspects, such as water confidence, breath control, body positioning, propulsion, coordination, and safety awareness. Additionally, self-reported mental health outcomes were measured, including emotional well-being, life satisfaction, self-esteem, sense of purpose, resilience, and social connectivity. The findings suggest that respondents usually have high confidence and proficiency in swimming abilities. However, there needs to be more understanding of safety measures, highlighting the need to enhance education on recognizing hazards and following safety procedures. Although respondents were skilled swimmers, they said that participating in swimming activities did not substantially impact their mental well-being, self-esteem, sense of purpose, resilience, or social connectivity. Nevertheless, a significant correlation between swimming proficiency and mental health outcomes was established, indicating that enhancing swimming abilities might benefit mental well-being. The study revealed many primary obstacles to participation in swimming, such as financial limitations, cultural and societal expectations, difficulties in accessing facilities, safety and health worries, and educational and psychological hindrances. The obstacles differ across different demographic groups, emphasizing the need for focused solutions.

Authors: Wu Jiaqi
Published: October 2024

In today's environment of openness to relationships, it is common for college students to fall in love. The effects of communication and sense of security in romantic relationships are increasingly significant. This paper aims to explore the intrinsic connection between communication styles and sense of security among college students in romantic relationships. In this work, 387 college students in romantic relationship were selected as research subjects through questionnaire survey, and the Sense of Security Questionnaire (SQ) and Satir Coping Stance Scale (SCS) were used as research tools. In this paper, the result shows that: (1) there was a gender difference in security; (2) there was a difference in the security between only and non-only child; (3) there was no significant in the security between grades and in the communication stance between genders(P>0.01); (4) congruent communication had a positive predictive effect on security, and the result of non-congruent communication were not significant. The conclusion as follows: Firstly, girls’ security is significantly lower than boys’ security. Second, non-only children’s security is significantly lower than only children. At last, congruent communication can increase individual’s level of security. These findings enrich the theoretical framework of the relationship between communication and security, and it also provides ideas on how to build a stable relationship for college students love.

3D Point Cloud Semantic Segmentation based on Multi-scale Dense Nested Networks
Authors: Wang Zishuo , Lai Tianxiang , Wang Yufeng , Gao Xingquan
Published: October 2024

Aiming at the problem that the relationship between geometric features and semantic features is ignored in the point cloud data downsampling process, which leads to inaccurate segmentation of object boundaries and structural details, this paper proposes a 3D point cloud semantic segmentation network based on multi-scale dense nested type. Firstly, a dense nested network architecture is constructed by nesting multiple multi-scale feature fusion modules to fuse multi-scale features of different directions between encoder-decoder paths, so as to effectively propagate local ge-ometric context information and enhance the ability of cross-scale information interaction. Secondly, a local feature aggregation unit is constructed in the multi-scale feature fusion module, which strengthens the structural awareness within the local point set based on graph convolution and attention mechanism, and promotes the complementarity of local geometric features and abstract semantic information. Then, the cross-layer multi-loss supervision module is combined to further optimize the multi-scale feature propagation, which makes the network training more stable and improves the point cloud segmentation accuracy. Finally, this paper verified the proposed network on the S3DIS dataset. The experimental results show that the proposed network has the mean intersection over Union of 71.2% and the overall accuracy of 88.7%, which is 1.2 and 0.7 percentage points higher than RandLA-Net, respectively, which proves that the proposed network can effectively improve the accuracy of 3D point cloud semantic segmentation.

Keuzevrijheid ten aanzien van het eigen levenseinde: Straatsburgse perspectieven
Authors: Lawson Rick
Published: October 2024

Recent zijn pogingen ondernomen om de mogelijkheden voor euthanasie en hulp bij zelfdoding in Nederland te verruimen. Zo werd het initiatiefwetsvoorstel ‘Voltooid Leven’ ingediend, en bepleit de Coöperatie Laatste Wil voor de rechter dat een ieder het recht toekomt om over het eigen levenseinde te beschikken. Daarbij wordt verwezen naar het EVRM, maar ook naar rechtspraak in Duitsland en Oostenrijk. Tegenstanders zijn er ook. In de recente zaak Mortier werd voor het EHRM betoogd dat de Belgische euthanasiepraktijk onverenigbaar is met het recht op leven. In hoeverre laat de Straatsburgse jurisprudentie ruimte om de Nederlandse praktijk nog verder te ontwikkelen; in hoeverre bestaat er zelfs een verplichting om dat te doen of, omgekeerd, bestaande mogelijkheden te beperken of zelfs helemaal terug te draaien?
De nevelen van de oorlog ontsluierd

Onderzoek speelt een cruciale rol tijdens gewapend conflict, en in de nasleep ervan. De nevelen van de oorlog, de zogenaamde ‘fog of war’, verhullen wat zich op de grond afspeelt. Dit kan het welhaast onmogelijk maken voor oorlogsslachtoffers om te achterhalen wat  en is overkomen, waarom dat is gebeurd, wie er verantwoordelijk is, en of ze een recht op rechtsherstel en toegang tot een rechtsmiddel hebben. Dit artikel beoogt te verhelderen wat de reikwijdte is van, en welke standaarden gelden onder,  onderzoeksverplichtingen in de voor Nederland meest relevante mensenrechtenverdragen – te weten het Europees Verdrag voor de  Rechten van de Mens en het Internationaal Verdrag inzake burgerrechten en politieke rechten. Daarbij wordt ook aandacht besteed  aan de belangrijkste verdragen van het humanitair oorlogsrecht, te weten de Verdragen van Genève en de daarbij behorende  Additionele Protocollen.

Can ChatGPT-4 Diagnose and Treat Like an Orthopaedic Surgeon? Testing Clinical Decision Making and Diagnostic Ability in Soft-Tissue Pathologies of the Foot and Ankle
Authors: Hartman Hayden , Essis Maritza Diane , Tung Wei Shao , Oh Irvin , Peden Sean , Gianakos Arianna L.
Published: October 2024

Introduction:

ChatGPT-4, a chatbot with an ability to carry human-like conversation, has attracted attention after demonstrating aptitude to pass professional licensure examinations. The purpose of this study was to explore the diagnostic and decision-making capacities of ChatGPT-4 in clinical management specifically assessing for accuracy in the identification and treatment of soft-tissue foot and ankle pathologies.

Methods:

This study presented eight soft-tissue–related foot and ankle cases to ChatGPT-4, with each case assessed by three fellowship-trained foot and ankle orthopaedic surgeons. The evaluation system included five criteria within a Likert scale, scoring from 5 (lowest) to 25 (highest possible).

Results:

The average sum score of all cases was 22.0. The Morton neuroma case received the highest score (24.7), and the peroneal tendon tear case received the lowest score (16.3). Subgroup analyses of each of the 5 criterion using showed no notable differences in surgeon grading. Criteria 3 (provide alternative treatments) and 4 (provide comprehensive information) were graded markedly lower than criteria 1 (diagnose), 2 (treat), and 5 (provide accurate information) (for both criteria 3 and 4: P = 0.007; P = 0.032; P < 0.0001). Criteria 5 was graded markedly higher than criteria 2, 3, and 4 (P = 0.02; P < 0.0001; P < 0.0001).

Conclusion:

This study demonstrates that ChatGPT-4 effectively diagnosed and provided reliable treatment options for most soft-tissue foot and ankle cases presented, noting consistency among surgeon evaluators. Individual criterion assessment revealed that ChatGPT-4 was most effective in diagnosing and suggesting appropriate treatment, but limitations were seen in the chatbot's ability to provide comprehensive information and alternative treatment options. In addition, the chatbot successfully did not suggest fabricated treatment options, a common concern in prior literature. This resource could be useful for clinicians seeking reliable patient education materials without the fear of inconsistencies, although comprehensive information beyond treatment may be limited.
A look at the possible impact of Apple's new policy on third-party apps and the data food chain of iOS users
Authors: Zhang Miaomiao
Published: October 2024

The research presents and discusses that Apple's new policy of applying the privacy application framework "App Tracking Transparency" to Apple's IOS14 system has implications for third-party companies in the data food chain as well as users. Users has paid attention to private information including consumption habits, spending power, product preferences, price sensitivity. We found that Apple's new Privacy Application Framework gives Apple absolute dominance in the data food chain of smart media users, Apple and the Apple ecosystem, third-party application platforms, and downstream marketing companies that provide data mining analysis for third-party applications, changing the traditional equal relationship between third-party application platforms and their direct access to user data.
How Does the Comprehensive Social Public Participation Affect Perceptions of Social Justice?
Authors: Zhou Shimo , Xie Chenmin
Published: October 2024

This study reveals the complex effects of the government service perception and different types of the comprehensive social public participation on the comprehensive perception of social justice and its sub-dimensions through OLS regression. Specifically, we find that the government service perception exhibits extremely significant and robust positive effects in all models. At the same time, the impact of different types of the comprehensive social public participation on perceptions of social equity shows significant variability. Rights advocacy participation demonstrates a negative effect in the model of the sense of legal and opportunity equality. This finding that suggests we need to further examine and optimize the advocacy mechanisms. The negative role of communication engagement in all sub-dimension models reveals the inadequacy of information transfer and communication mechanisms in building social trust. In contrast, the positive effect of community participation in the model of the sense of legal and opportunity equality highlights the positive role of communities in promoting social fairness, while the overall positive effect of electoral participation, although weakly significant in some sub-dimensions, suggests the potential value of the electoral system in enhancing the sense of social fairness.
Study on the English translation of excerpts from Mencius: Gong Sun Chou based on translator’s subjectivity
Authors: Kan Jing
Published: October 2024

The translator is the subject of translation, serving as a medium for cultural exchange and communication. However, translators in the external dissemination of Chinese culture have long been neglected and marginalized. With the “cultural turn” in translation studies, translators have gained due attention. As one of the representative works of Confucianism, Mencius is an important part of traditional Chinese culture, but its foreign translation is later than the Analects of Confucius and other classics, which also reflects the problem of scholars’ insufficient investment in its research. This paper makes a comparative analysis of how the English translation of the core concepts of Mencius by James Legge, Derk Bodde and D.C. LAU reflects the translator’s subjectivity, and in turn how the translator’s subjectivity affects their translation strategy, in order to make a contribution to the foreign translation of classics.
Numerical Simulation of Mechanical Properties of Deep Gray Sandstone with Holes and Radial Cracks
Authors: Yuan Lele
Published: October 2024

In order to study the effects of prefabricated pore-fracture on the mechanical properties, crack extension and energy evolution of rocks under uniaxial compression, the effects of rock samples containing pore-fracture deep grey sandstone on the mechanical properties, crack extension and energy evolution of rocks were analysed in detail through the indoor experimental inverse performance of the fine-scale mechanical parameters of the PFC3D model. The results show that the mechanical parameters of deep grey sandstone samples with pore fissures are significantly lower than those of intact samples, and the decrease is closely related to the diameter of the pore as well as the length and width of the fissure, with the increase of the diameter of the pore, the peak strength and the peak strain of deep grey sandstone with single pore are in the trend of attenuation, and the mechanical parameters of deep grey sandstone samples with pore fissures of different lengths and widths are in the trend of attenuation with the increase of fissure widths and lengths of different layers. The mechanical parameters of deep grey sandstone samples with different lengths and widths of fissures show a trend of attenuation with the increase of fissure width and length; based on the analysis of microscopic crack characteristics during loading of deep grey sandstone with pore fissures, it is concluded that the cracks produced by deep grey sandstone samples with pore fissures are mainly distributed at the two ends of the samples, and the middle area has fewer cracks and the number of the cracks produced shows a trend of attenuation with the increase in the diameter of the pore as well as the length and width of the fissure; Based on the energy evolution mechanism, it is concluded that as the pore size of the rock sample increases, the strain node at which the dissipated energy begins to appear becomes progressively earlier, the energy storage capacity of the rock appears to be drastically reduced, and the internal damage becomes more and more severe.

Research on Blockchain Interactive Zero Knowledge Proof Privacy Protection Scheme Based on Improved Paillier Homomorphic Encryption
Authors: Zhuo Yueran
Published: October 2024

In the context of the digital age, data privacy and security issues are increasingly prominent. Blockchain technology plays an important role in data sharing due to its transparency and immutability, but it also brings the risk of privacy leakage. Zero knowledge proof technology provides a solution for verifying data correctness without exposing data content, which is particularly important for blockchain as it can ensure the validity and compliance of transactions while protecting user privacy. Although zero knowledge proof is quite mature in theory, its application in blockchain systems still faces challenges such as computational efficiency, complexity of smart contracts, and system compatibility. This study aims to propose a privacy protection scheme that supports interactive zero knowledge proof by improving the homomorphic encryption Paillier algorithm, in order to enhance the privacy protection capability of blockchain systems and maintain system efficiency and security. The study will adopt an interdisciplinary approach, combining cryptography, computer science, and network security theory, to deeply analyze the application effect of zero knowledge proof technology in blockchain, explore its optimization space and applicability.
