Effect of Financial Leverage on Financial Performance of Listed Industrial Firms in Nigeria
Authors: A. Ibrahim, , J. T. Gimba, , D. D. Ezekiel, , C. K. Osama,
Published: October 2024

The research explores how the use of financial leverage impacts the financial performance of listed industrial companies in Nigeria from 2018-2022. To assess financial leverage, it utilised the total debt-to-asset ratio and interest coverage ratio as proxies, while gross profit margin was used as a measure of financial performance. The data was analysed using panel data, which included information from the individual financial statements of the listed industrial companies. The dataset consisted of thirteen (13) industrial companies listed on the Nigerian Stock Exchange Group (NGX). The research utilised a panel regression model to determine the main relationship between financial leverage and gross profit margin. The result shows that the total debt-to-asset ratio had a positive significant effect on the gross profit margin of listed industrial firms in Nigeria. Interest coverage ratio had a negative significant effect on the gross profit margin of listed industrial firms in Nigeria. The management of the industrial firms should employ more sustainable debt financing to critical areas of the firm’s investment for asset expansion, in order to gross profit and financial performance of the firm. The study also recommends that industrial firms in Nigeria should consider debt with a lower percentage of interest coverage. This will minimise its capital cost, reduce the risk of default on loan payments and help the financial managers improve the financial performance of the firm.

Published: October 2024

This study examined the impact of domestic violence on the academic performance of school-aged children and adolescents in Abeokuta South Local Government Area, Ogun State, Nigeria. Structured questionnaire was used in the study to elicit information from students, teachers, and parents to assess the prevalence of domestic violence and its correlation with academic performance. Descriptive statistics, such as frequency counts and percentages, and inferential statistics like Pearson’s Product Moment Correlation and chi-square analysis, were used to analyse the data. The findings revealed that 80% to 100% of students had experienced some form of domestic violence, which led to academic challenges such as absenteeism, poor concentration, and diminished school engagement. Further, the form of domestic violence experienced were tenable to negatively impact their academic participation profile as physical abuse did not have a significant correlation with students’ participation (r = -0.06, p = 0.212 > 0.05), but had a negative significant correlation with academic performance (r = -0.10, p = 0.038 < 0.05), class participation (r = -0.13, p = 0.010 < 0.05), behavioral pattern (r = -0.10, p = 0.043 < 0.05) and a highly significant correlation with discipline (r = -0.14, p = 0.005 < 0.01). Emotional abuse only established a significant correlation with students’ attendance (r = -0.14, p = 0.004 < 0.01) while sexual abuse had a significant but negative correlation with academic performance (r = -0.15, p = 0.002 < 0.01) in addition to student attendance (r = -0.12, p = 0.018 < 0.05), class participation (r = -0.14, p = 0.004 < 0.01) and behavioral pattern (r = -0.15, p = 0.003 < 0.01). There was equally a correlation between property destruction (r = -0.104, p = 0.005 < 0.05) and behavioral pattern (r = -0.124, p = 0.049 < 0.05) and academic performance. The study concluded that domestic violence hinders children's educational progress and emphasizes the need for targeted interventions in schools and communities to address its adverse effects. The research contributes to a broader understanding of the relationship between domestic violence and academic outcomes in Nigeria.

В статье рассматривается разработанная авторами методика учета идеальных шарнирных соединений конечных элементов стержневых и пластинчатых систем при расчете по методу конечных элементов (в форме классического смешанного метода). Постановка шарнирных соединений производится путем удаления элементов из матрицы откликов системы конечных элементов, физический смысл которых соответствует изгибающему моменту по направлению работы шарнира, что означает исключение соответствующих им неизвестных из системы разрешающих уравнений. Рассмотрены примеры расчета систем, состоящих из пластинчатых и стержневых конечных элементов с постановкой идеальных шарнирных соединений в их узлах. Сделаны выводы о возможностях автоматизации процесса постановки шарниров при разработке программного комплекса, реализующего метод конечных элементов в форме классического смешанного метода.

Published: October 2024

В данной статье представлен опыт восстановления функциональности носовой перегородки при ринопластике у пациентов с врожденной деформацией крыла носа, перенесенных хейлопластику. В настоящее время у пластических хирургов существует три основных подхода к исправлению искривленной носовой перегородки: подслизистая резекция по Киллиану и её вариации, септопластика и экстракорпоральная септопластика. Цель исследования заключалась в повышении эффективности экстракорпоральных реконструктивных операций для пациентов с деформацией носовой перегородки и изменением формы носовых крыльев. В 2024 года в отделении челюстно-лицевой хирургии Ошской межобластной клинической больницы было проведено 11 повторных риносептопластик у пациентов с различными деформациями крыльев носа и искривлением носовой перегородки. В состав пациентов входили 4 женщины (36,3%) и 7 мужчин (63,7%) со средним возрастом 25,7 лет. Были выполнены открытые ринопластики для коррекции двух седловидных носов с использованием реберного ауто-хряща, а также операции по иссечению горба и укреплению носовой перегородки с применением собственного перегородочного хряща. Для коррекции деформации крыльев носа использовался ушной хрящ. Результаты показали, что использование открытого ринопластического доступа в сочетании с экстракорпоральной септопластикой способствует удовлетворительным и долговременным функциональным и эстетическим результатам в ринопластике.

Numerical Investigation of a 3 Kw Microturbine Combustion Chamber
Authors: Sinkevich M.V.
Published: October 2024

Numerical simulation is crucial the development of microturbines because it allows to investigate the combustion process in the combustion chamber without the need of manufacturing expensive physical prototypes at early stages of development. This paper presents a numerical investigation of the combustion process occurring in a 3 kW microturbine combustion chamber. First, a computational model of an existing 30 kW microturbine combustion chamber design was developed. The results obtained were compared with experimental data to ensure the adequacy of the results obtained. After validation, a computational model of the 3 kW microturbine combustion chamber was developed. Three configurations of the 3 kW microturbine combustion chamber with different locations and numbers of dilution holes were investigated. Configuration 3 of the 3 kW microturbine combustion chamber showed the lowest standard deviation in outlet temperature (48.4 K) and velocity (29.7 m/s), indicating a more uniform temperature and velocity profile at the outlet compared to the other two configurations. While Configuration 3 had a higher pressure loss (1059 Pa) than the other configurations (939 and 836 Pa), the priority at this stage of development was placed on achieving optimal uniform temperature and velocity profiles at the combustion chamber outlet.

Published: October 2024

This paper presents a description of the design and operating principle of a pulse variator for transmitting torque. CVTs are used in mechanical engineering – in vehicle transmissions to transmit torque, slow down the speed of shaft rotation and in drives of a wide variety of technological equipment. The pulse variator contains: a fixed housing in which the drive gear, satellites, driven gear, carrier, drive gears, and drive shaft are installed. With the help of a differential type planetary mechanism, rotational motion and torque are transmitted from the drive gear to the driven gear by slowing down the speed of rotation of the carrier, using an impulse mechanism, which creates the braking torque necessary to transmit torque from the drive gear to the driven gear of the differential mechanism. By changing the angle of inclination of the washer and moving the slider along the spline shaft, the magnitude of the braking torque on the carrier and the rotation speed of the driven shaft are adjusted depending on the magnitude of the moment of resistance on the driven shaft. The advantage of the described variator design is the ability to regulate the speed of the driven gear depending on the magnitude of the moment of resistance on the gear, increasing the efficiency of the device, reducing heat losses, improving the reliability and durability of the device.

This paper presents a description of the design and operating principle of an inertial variator, which can be used to transmit torque, slow down the speed of shaft rotation and in drives of a wide variety of technological equipment. The inertial variator presented in the article consists of a fixed housing in which the drive gear, satellites, driven gear, carrier, drive gears, drive shaft and impulse mechanism are installed, which is based on the design of the cardan mechanism. With the help of a differential type planetary mechanism, rotational motion and torque are transmitted from the drive gear to the driven gear by slowing down the speed of rotation of the carrier, using an impulse mechanism, which creates the braking torque necessary to transmit torque from the drive gear to the driven gear of the differential mechanism. By changing the angle between the forks of the cardan mechanism, the magnitude of the braking torque on the carrier and the rotation speed of the driven shaft are regulated depending on the magnitude of the moment of resistance on the driven shaft. The advantage of the described variator model is the ability to regulate the speed of the driven gear depending on the magnitude of the moment of resistance on the gear, increasing the efficiency of the device, reducing heat losses, improving the reliability and durability of the device.

Authors: Mohazab Pegah , Ghasemi Samad , Heidarpour Akbar
Published: October 2024

The carbothermic reduction of  MoS2 using Mg, an efficient sulfur scavenger, was carried out by two very different routes, i.e., mechanochemical reaction and heat treatment. The thermodynamic calculation results show that Mo2C and MgS are the phases formed when the elements are combined, and carbothermic reduction of molybdenite takes place. XRD analysis data indicates no reaction occurred at 1, 2, and 5 h of milling by the mechanochemical method, and the initial phases MoS2, Mg, and C were identified. On the other hand, after 7 hours of milling, Mo2C and MgS phases finally emerged. Through heat treatment, the desired Mo2C and MgS phases were successfully prepared with the crystal diffraction spots obvious at 700, 800, and 900 °C, respectively. Both of these methods produced powders which were then washed with a 10% 1M HCl solution, and as a result, a reasonable yield of pure molybdenum carbide was obtained.

THE LATEST PARADIGM SHIFT IN FORENSIC GENETICS - MASSIVELY PARALLEL SEQUENCING AND LARGE VOLUMES OF DATA
Authors: Toppinen M. , Sajantila A. , Budowle B.
Published: October 2024

Over the last several decades forensic genetics has evolved to provide extremely sensitive and highly resolving results for human identification in criminal cases and humanitarian efforts. The advent of DNA databases increased the power of forensic DNA typing even further by rapidly developing investigative leads. Even with the current methods, markers and databases, hundreds of thousands to millions of criminal, civil and humanitarian cases have not been resolved even though biological evidence is available. To address this deficiency the forensic genetics community is poised for a paradigm shift fuelled by the advent of massively parallel sequencing and a reinvigoration of genetic markers known as single nucleotide polymorphisms. Two examples – forensic genetic genealogy for human identification and virome analyses for geolocation – are discussed to illustrate the power and future of forensic genetics or more appropriately termed forensic genomics.
Keywords: forensic genetics, human identification, massively parallel sequencing, single nucleotide polymorphisms, forensic genetic genealogy, virome, geolocation.

The Informal STEM Learning (ISL) project1 research team from the STEM Research Center at Oregon State University, in collaboration with project partners, conducted a baseline survey with members of the informal STEM learning community. The main goals of the ISL Baseline Survey were to 1. Understand the current lived experiences of ISL professionals and determine factors around professional learning that might enhance belonging to institutions and the field of ISL, and success individual’s careers in ISL; and 2. Gain insights into current awareness and knowledge of the Framework and perceived needs in the community to make the Framework useful and usable for a variety of purposes. Findings from the baseline survey complement data from listening sessions and transference panels. Collectively, the project team can use baseline survey findings to inform the development of resources for the Framework, including how to best socialize the Framework into the ISL community. The survey was based on a similar survey to the ISL community conducted by the Center for the Advancement of Informal STEM Learning (CAISE), further co-developed by all project partners, and disseminated from contact lists from the Association of Science and Technology Centers (ASTC). 732 respondents started the survey, and 630 completed at least one scale of survey items. This summary shares high-level findings from our initial analysis of the survey data of those 630 respondents to the survey.
Schmidt number and turbulent structures in boundary layer aeolian sand transport
Authors: Aissa Hadjaissa , Zaki Salameh Tareq Samir
Published: October 2024

This study investigates the influence of the Schmidt number (Sc), a crucial input parameter for simulating aeolian sand transport processes, which relates fluid motion to the diffusion of sand particles. While (Sc) directly influences mass diffusion, its effects on turbulence structures are more indirect. By examining this parameter, researchers can gain valuable insights into the complex interactions between wind and sand particles, leading to improved understanding and modeling of aeolian processes. Direct numerical simulations based on the mixture model theory have revealed a significant influence of Schmidt number on the dissipation rate of turbulent sand-air flows within boundary layer. Although changes in Schmidt number do not consistently alter dissipation rate values, a convergence is observed within the range of Sc=0.7 to Sc=0.9, which corresponds to certain intervals of similar phenomena. We observed distinct spatial distributions of sand grains between saltation and suspension modes, influenced by both Schmidt number and sand grain size. These findings contribute to a deeper understanding of aeolian processes and offer valuable insights for modeling sand transport in diverse environmental conditions.
Proposition of a new tool for the election of group decision support system facilitator based on the multi-criteria approach
Authors: Taieb Sabir Mohammedi , Laredj Mohamed Adnane
Published: October 2024

The Breakdown of a modern industrial machine requires the intervention and collaboration of a group of experts in order to provide a diagnostic and a fix. This intervention can be done through the internet. This process is called collaborative e-maintenance. In order to provide these experts with a collaborative environment th         at works remotely, we use a Group Decision Support System (GDSS). Which improves the effectiveness of the process and reduces the loss in time and information. This system requires a human facilitator who coordinates and plans the meeting. His counterpart in the collaborative e-maintenance process is one of the experts called the coordinator. This leader is extremely important and has to have certain qualities that can be represented in the form of election criteria. The facilitator election process can be implemented and automated by a machine through different solutions. An interesting alternative is to use Multi-Criteria Decision Aid (MCDA) methods. Which aims at choosing the alternative that satisfies multiple decision makers by considering multiple criteria. Our aim in this paper is to compare the outcome of using different MCDA methods in the problematic of electing a GDSS facilitator. Furthermore, a new election tool is proposed for choosing the GDSS facilitator, and is integrated within a collaborative e-maintenance model.
Discurso e ensino: uma análise da memória em torno do Holocausto no livro didático e na Base Nacional Comum Curricular (BNCC)
Authors: Zevierzecoski Josiele , Teixeira Maria Claudia
Published: October 2024

O presente trabalho tem como objetivo analisar o modo como a memória sobre o Holocausto é construída e discursivizada na Base Nacional Comum Curricular (Brasil, 2018) e no livro didático História sociedade e cidadania (2018), do 9º ano, Ensino Fundamental e, consequentemente, ensinada nas escolas brasileiras. Para isso, tomamos como base teórico-metodológica a Análise de Discurso de linha pecheuxtiana, mobilizando as noções de discurso, memória e suas relações com a história. Nosso corpus de análise constitui-se de recortes das materialidades discursivas em tela, organizados em sequências discursivas que, pelo nosso gesto analítico, apontam para a (re)significação da memória sobre o Holocausto no espaço escolar. As SDs sinalizam que a memória sobre o Holocausto, construída pelo discurso pedagógico nas materialidades analisadas, sustenta-se no ódio, perseguição e a criação de um imaginário social constituído a partir do nazismo, de que os judeus eram os culpados pela desgraça da Alemanha e, por isso, deveriam ser exterminados. Desse modo, a história discursivizada no livro, não é estanque, mas (re)constrói e (re)significa memórias que produzem efeitos de sentidos no presente, efeitos de sentido de alerta, que encaminham para o cuidado que se deve ter com a discriminação, ódio, preconceito e qualquer prática que desvalorize o ser humano por suas escolhas religiosas, por sua cor ou orientação sexual, pois as práticas discriminatórias podem resultar em uma tragédia.
O conceito de angústia na clínica psicanalítica e seus desdobramentos na contemporaneidade
Authors: Penna Paula Dias Moreira , Paula Diuly Abood de
Published: October 2024

A presente pesquisa explorou a evolução conceitual da angústia, com base em estudos psicanalíticos e sua relevância diante da clínica contemporânea. A pre- sença significativa da angústia na prática clínica atual revela os impactos subje- tivos e efeitos produzidos pela cultura vigente. O objetivo foi analisar e descrever como o conceito de angústia foi desenvolvido e compreendido ao longo do tempo, com foco nas contribuições de Sigmund Freud e Jacques Lacan, e como é possível fazer uma leitura dos fenômenos contemporâneos que permeiam a clínica e as vivências subjetivas. A metodologia envolveu uma revisão bibliográ- fica e qualitativa da literatura, partindo de Freud, que relacionou a angústia à perda do objeto, ao perigo e ao desamparo. Em seguida, o conceito foi abordado por Lacan, que o caracterizou como um afeto que não engana e que revela a falta dos sujeitos, estabelecendo relação com o desejo. Com isso, explicita-se a relação da angústia com o excesso contemporâneo e se percebe como as ca- racterísticas da sociedade atual, marcada pela pressa e pelo excesso, se des- dobram na construção sintomática da época. Conclui-se que a psicanálise ofe- rece perspectivas importantes para compreender o lugar da angústia na contemporaneidade e, em contramão ao que se espera na atualidade, não se busca suprimir o afeto, visto que ele pode inclusive atuar como motor do tratamento e revelar o lugar do desejo.

Published: October 2024

The occurrence of landslides is characterized by suddenness and unpredictability, with many complex relationships among various influencing factors. This study, by introducing the ontology of knowledge engineering, summarizes the characteristics of landslide knowledge and constructs a multidisciplinary, multi-level, and multi-perspective ontology of the landslide domain. Through in-depth analysis of existing landslide research systems and methods, the study defines the basic concepts, attributes, and their complex relationships and rules related to landslides. This research expresses landslide knowledge using the Web Ontology Language (OWL), enabling effective storage and retrieval of landslide knowledge, thus promoting the systematization and standardization of knowledge in the landslide domain. Furthermore, leveraging the high knowledge density feature of the constructed landslide domain ontology, this study extends traditional landslide evaluation and prediction methods by introducing more evaluation indicators based on the constructed landslide ontology. The comprehensive evaluation of landslide risk is conducted using the contribution-weighting method, providing new insights and tools for landslide risk management and decision-making.

Spatio-temporal Evolution of Land Use in Guangdong-Hong Kong-Macao Greater Bay Economic Area, 1985-2022 and Analysis of Influencing Factors
Authors: Sheng Keding , Mei Xingshuai , Yang Xitong
Published: October 2024

This research employs GIS and remote sensing technology, along with time-series Land cover data, to examine the evolving patterns of various land use categories (such as forest land, cultivated land, and impervious surfaces) within the Guangdong-Hong Kong-Macao Greater Bay Area. The results indicate that the predominant spatial configuration of land use in this region follows a sequence of "forest land-cultivated land-impervious land." Notably, the key transformation observed involves the conversion of cultivated land to impervious surfaces, resulting in a cumulative expansion of impervious areas by 3,346,985 hectares between 1985 and 2022. Moreover, the level of spatial integration among land use types in the Greater Bay Area is progressively standardizing, with notable advancements in scientific, technological, economic, and transportation sectors leading to a high degree of synergy. The system as a whole demonstrates effective coordination and operational efficiency. The methodology section outlines the data sources and analytical techniques employed, encompassing the utilization of the land use transfer matrix, individual land use degree assessment, and spatial coupling function model. Through these methodologies, the study identifies urban economic development as the primary driver behind the proliferation of impervious surfaces, offering valuable insights to inform regional development strategies and environmental governance policies.

Published: October 2024

Through a review of relevant literature,this study categorizes factors affecting real estate site selection into three main categories: environmental, social, and economic, termed as the "triple bottom line." Based on the "triple bottom line," a PUM (Portfolio Underwriting Model) model was constructed. Meanwhile, GIS technology was utilized to identify the locations of public transportation stations, medical institutions, schools, and fire stations within Xiamen City. Additionally, different regions were delineated into suitable residential areas based on slope, aspect, land type, and per capita GDP. Combining the PUM model with GIS technology ultimately aids in real estate market site selection. The research findings indicate that integrating the PUM model and GIS technology for real estate site selection allows for a more scientific and comprehensive evaluation of various site selection factors, thereby providing important decision-making support for developers and investors.
Sustainability analysis of building materials
Authors: Meng Yibo
Published: October 2024

Our analysis of the sustainability of building materials is often overly simplistic. When we think of sustainable materials, it's easy to think of wood, rattan, bamboo, or stone, which are grown in nature, taken from nature, and are undoubtedly renewable resources or renewable materials. However, it would be a dull stereotype to assume that these materials represent an analysis of sustainable materials in construction. Regardless of whether a particular material is suitable for all time and space environments, even if we reduce the consideration of design function, what is the relationship between the serious pollution caused by the huge amount of resources consumed by long-distance transportation over mountains and mountains and green design or sustainable design, not to mention that inappropriate materials may lead to a decline in the quality of the design product, shorten the service life of the design product, and bring more serious waste of resources. In conclusion, there is a lot to discuss about the sustainability of building materials. Green building space design and sustainable building materials analysis is a very complex topic that involves many aspects and the application of knowledge from many disciplines. The sustainability assessment of building materials can lead to at least the following topics: the choice of building materials themselves, building design methods, energy efficiency and the environmental impact of building design. The examples of materials we have just listed, such as wood, bamboo, rattan, are actually based on the perspective of the choice of the material itself, and it cannot be said that there is anything wrong with this, but this analysis is too narrow. This paper will comprehensively analyze and evaluate the sustainability of building materials in terms of material selection, design, utilization and environmental impact, and try to provide a more mature evaluation method or thinking process to assess the sustainability of building materials.
