THE ARTISTIC PURPOSE OF ALISHER NAVOIY'S RHYME
Authors: Hamroyeva Orzigul
Published: December 2024

Rhyme is not merely an element based on repetitions at the end of lines, but one of the crucial components in conveying the essence of a poem. Navoiy's works are distinguished by their remarkable diversity in all aspects. They include events, characters, nature, objects, grandeur, buildings, places, and times, as well as descriptions and narratives. Metrics, rhyme, saj’ (rhymed prose), and artistic devices vary in each chapter, section, couplet, and verse of a work. Moreover, there is not a single chapter, section, couplet, or verse, nor a single word, meaning, or sound that lacks a unique aspect.
The artistic role of rhyme in poetry is of significant importance, as the chosen rhyme determines the poem's artistic value through its core essence, depth, melodic quality, artistic value, and even the harmony of sounds, functioning as an entire system. The poet’s poetic thought is vividly apparent in this. The poetic genres and their substantive and formal characteristics influence how rhyme is presented in lines and stanzas. Even within a single ghazal (lyric poem), the rhyme varies according to the thematic and formal requirements of each type. Through rhyme, the essence and spirit of the ghazal are defined. Thus, rhyme is not merely a melodic element but one of the crucial poetic units that define the essence of the poem. Below, the impact of rhyme on the essence of the ghazal in Navoiy's lyrical legacy is examined.

Modelling education equality through online platform adoption: Insights into the digital divide, fairness, perceived ease of use, and usefulness
Authors: Jiang Songyu , Zhu Hao , Li Hao , Li Ruiming
Published: December 2024

Online education platforms are pivotal in achieving educational equity. This study employs grounded theory to examine the factors influencing the adoption of online education platforms by students and educators in Chinese higher education institutions. Data were collected through semi-structured interviews with 30 participants, including 15 students and 15 educators, to provide a detailed qualitative analysis. The findings identify critical factors affecting platform adoption, including digital accessibility and infrastructure, user experience and interface design, adoption and integration challenges, and the impact on educational outcomes and equity. Significant disparities in digital access, especially between urban and rural areas, underscore the need for enhanced digital infrastructure to ensure equitable access to online education. The usability of the platforms, facilitated by user-friendly interfaces and comprehensive training, emerged as essential for engaging students and educators effectively. The study also highlights technological challenges and a lack of digital literacy as significant barriers, necessitating targeted interventions like digital literacy programs and robust technical support.
Heritage-based design
Authors:   Delft University of Technology, The Netherlands, Meurs Paul
Published: December 2024

This book addresses the question of how to design in a historical context. How to get a grip on a site? How can a designer incorporate actual qualities of the heritage in the design? In three chapters, it is described how the conservation of heritage has increasingly become an issue of planning and intervention, with the specific cultural heritage qualities of a site as the starting point for transformation.

There are several different approaches to embed the design in the site: focussing on the designed past, the designed presence and the non-designed presence. The better the essences of the meaning of the cultural heritage (substance, structure and narrative) are exposed, the better the design can focus on these. However accurately the different process steps are adhered to — in the end the quality of the design will determine the degree of success: it’s a thin line between a disaster and a brilliant intervention. The design challenge is to give a site new vitality while at the same time preserving its value.

Over the past decade, my office has dealt with all kinds of interventions and new developments. In teams of designers and historians, we have analysed buildings, areas and landscapes to discover their visible and invisible qualities. How did they become what they are today? What were the ideas and ideals at the time of their realisation? To what extent has a site withstood the test of time, and how can the concepts, structures and stories from the past be deployed in current challenges? We gradually try to get to the core: the legacy for the future and the exact nature of the assignment — viewed from the perspective of the cultural heritage value. Defining that value is a design on its own, just like history itself is. It is a creative process, in which the views and opinions of others carry considerable weight, but where you as the specialist will have to make the final assessment to arrive at decisions and legitimation. This will create a heritage base for the design to respond to and build upon.

This book is part of a series of books produced in cooperation with and financed by the Stichting Rondeltappe-Bernoster-Kemmers. All books of the series have been reviewed and edited by Silvia Naldini, Section of Heritage & Architecture, Faculty of Architecture and the Built Environment, Delft University of Technology, The Netherlands.

A violência política contra as mulheres em perspectiva interseccional (VPCMI)
Authors: Matos Marlise , Gonçalves Viviane , Monteiro Ester
Published: December 2024

2022 elections were the first ones in which we had laws criminalizing political violence in Brazil: Law 14,197/2021, about political violence in general; and Law 14,192/2021, which specifies political violence against women (PVAW). In MG, Law 24,466/2023 was created with the Program to Combat Harassment and Political Violence against Women and the state became the first one in Brazil to have a specific legislation on the theme. However, there are still no consolidated rules on the competencies or responsibilities of the institutions that should get involved in preventing and punishing PWAW. This lack of definition leads to more violence. In the last two quarters of 2023, the states of Minas and São Paulo led the records of political violence against women (OVPE/Unirio). In Minas, specifically, parliamentarians at the three legislative levels have continually suffered threats. Thus, in the article at hand, we seek to understand and denounce the phenomenon in the state, in addition to supporting debates on the creation of a network to combat “political violence against women from an intersectional perspective”.

Blood preservatives (anticoagulants) prevent blood from clotting while ensuring that the concentration of the component to be analysed stays constant prior to the analytical procedures. The study was aimed to evaluate the effects of different anticoagulants, such as ethylenediaminetetraacetic acid (EDTA), fluoride oxalate, sodium citrate and lithium heparin, on the haematological parameters of African catfish (Clarias gariepinus). Forty fish were obtained and separated into four groups representing the four treatments. Blood samples were collected from ten fish from each group and stored in separate anticoagulant laden bottles. Lithium heparin was used as control in this experiment. Each sample was processed, and values of the parameters were recorded. The RBC, haemoglobin, and PCV of the anticoagulants used were similar as no significant difference (P > 0.05) was revealed among the treatments. The heterophil levels of fluoride oxalate treatment group was significantly higher than control, this in turn led to an increase in HLR (heterophil-lymphocyte ratio). Therefore, the haematologic alteration observed in this study, which include heterophilia associated with fluoride oxalate anticoagulant, should be put into consideration when making a choice of anticoagulants for haematological analysis in C. gariepinus.

The Effect of Tax Avoidance on Liquidity, Profitability and Capital Structure PT. Bukalapak Tbk
Authors: Sri Widari
Published: December 2024

This study's overarching goal is to dissect the impact of tax evasion on the capital structure, liquidity, and profitability of PT. Bukalapak.com Tbk firms traded on the IDX from 2022 to 2024. This study used multiple regression analysis and a quantitative technique to find that capital structure, profitability, and liquidity impact tax evasion levels. There is a correlation between a company's liquidity and its propensity to participate in tax avoidance, and between a company's profitability and its propensity to use tax avoidance approaches to reduce cash outflows associated with tax payments. Because interest paid on debt is tax deductible, tax avoidance strategies are often accompanied with a capital structure that is heavily reliant on debt

NUMERICAL DESCRIPTION OF THE DISTRIBUTION OF n-PARAFFINS CONTENT IN VACUUM GAS OIL AND THEIR REACTIVITY IN THE HYDROCRACKING PROCESS
Authors: Belinskaya Nataliya S.
Published: December 2024

Currently, the process of hydrocracking of heavy petroleum feedstocks is one of the main processes that makes it possible to increase the depth of oil refining and to obtain high-quality motor fuel components, including diesel fuel components with improved low-temperature properties. In this paper, a review on the existing modelling approaches and models of the heavy oil feedstock hydrocracking process is presented. The object of the research is the process of vacuum gasoil hydrocracking. The work proposes the scheme of chemical transformations in the process of hydrocracking and the model of the process. The distinctive feature of the proposed chemical transformations scheme and a model is taking into account the hydrocracking reactions of individual n-paraffins. It is proposed to determine the content of individual n-paraffins in the feedstock of the process (vacuum gas oil) by the number of carbon atoms in the molecule based on the probability distribution, using the Gaussian function as a probability density function. The reactivity of individual n-paraffins in the hydrocracking reaction was taken into account via thermodynamic characteristics of the reactions of each individual n-paraffin determined using quantum-chemical methods. The calculation of the detailed composition of the target diesel product including the content of n-paraffins provides determination of cold filter plugging point, which is influenced by the content of n-paraffins to the most extent. The developed detailed model of vacuum gasoil hydrocracking process includes the equations for calculation of changes in concentrations of reacting component and change in the temperature of the process. The proposed approach to the modelling of the hydrocracking process makes it possible to optimize the process taking into account the detailed composition to get the maximum yield of low freezing diesel fuel.

The paper presents the results of a study of the electrical conductive characteristics and a complex of physical-mechanical properties of graphite-based nanocomposites, a wide range of polyolefins - low-density polyethylene, high-density polyethylene, isotactic polypropylene, random copolymer of polypropylene, block copolymer of propylene with ethylene, ethylene/hexene copolymer and ethylene/butene-1 copolymer. For the considered nanocomposites based on polyolefins, the optimal concentrations of graphite were determined, at which the maximum values of electrical conductivity are achieved, within the range of 10–2–10–3 (Ωm)–1. A detailed description of the mechanism of tunneling and electronic electrical conductivity in the nanocomposites under consideration is given. Thermoplastic elastomers (TPE) based on polyolefins and ethylene-propylene-diene rubber have been developed. In a wide concentration range, the regularities of changes in the electrical conductivity of nanocomposites based on thermoplastic elastomers and nanodispersed graphite have been determined. When studying the physical-mechanical properties of TPE nanocomposites, the tensile strength, yield strength, elongation at break, bending strength, Vicat softening temperature, melt flow rate, and Young's modulus were determined. The regularity of the change in the dependence "stress-strain" for TPE depending on the content of ethylene-propylene-diene rubber has been established. Using the methods of derivatography, X-ray phase and SEM analyses, and electron microscopy, studies were carried out to assess the structural features of nanocomposites of thermoplastic elastomers depending on the ratio of the mixture components used. For visual interpretation, a schematic representation of the processes occurring in the interfacial region of thermoplastic elastomers is given. The method of X-ray phase analysis shows the regularity of the change in the degree of crystallinity of thermoplastic elastomers depending on the content of rubber and graphite. The principal possibility of obtaining flexible electrically conductive materials with predetermined properties by controlling the ratio of components in the composition of thermoplastic elastomers is shown.

SYNTHESIS OF METAL-ORGANIC FRAMEWORK Ni-MOF USING 2-METHYLIMIDAZOLE AND APPLICATION FOR ADSORPTION OF ORGANIC PIGMENTS
Authors: Tac Dinh Van , Duyen Vu Thi
Published: December 2024

Among the metal-organic framework materials, Ni-MOF is considered one of the promising materials due to its high porosity and structure containing active transition metal ions. In particular, by changing the organic ligands and synthesis conditions, organic framework nickel materials with different structures and properties have been synthesized and evaluated for applicability in many fields. In this study, the metal-organic framework Ni-MOF was synthesized by solvothermal approach using the organic ligand 2-methylimidazole. The obtained material was characterized using infrared (IR) spectroscopy, X-ray diffraction (XRD), EDX spectroscopy and SEM images. The results of analyzing the physico-chemical properties of materials showed that the obtained material has a porous structure with a relatively low crystallinity. The surface morphology, elemental composition and crystallinity depend on the nature of the nickel salt and the molar ratio of nickel/2-methylimidazole ligand. The synthesized material was used as an adsorbent for the removal of MB and RhB from aqueous solution. The results showed that the synthesized Ni-MOF material has good adsorption capacity of organic pigments. The influence of synthesis conditions, including the molar ratio of nickel salt and 2-methylimidazole, synthesis temperature and synthesis time, on the adsorption capacity of Ni-MOF materials was studied. It was shown that Ni-MOF material synthesized by solvothermal method using nickel nitrate and 2-methylimidazole ligand with a molar ratio of 1:8, calcined at 180 °C after 8 hours, has the best adsorption ability for the removal of pigment from aqueous solution. The adsorption capacity of Ni-MOF for MB and RhB removal reached 105.45 mg/g and 51.48 mg/g, respectively.

SOLUTION OF THE INVERSE PROBLEM OF CHEMICAL KINETICS BASED ON FUZZY LOGIC MODELS
Authors: Kol'tsov Nikolay I.
Published: December 2024

The possibility of using “soft” calculation methods to solve the inverse problem of chemical kinetics to identify fuzzy kinetic laws based on the data of stationary experiments without a priori specifying the type of the kinetic law has been investigated. “Soft” computing combines artificial intelligence methods such as fuzzy logic, neural networks, genetic algorithms, etc. (F. Rosenblatt, L. Zadeh, J. Holland, etc.). Combinations of these methods will allow the creation of various hybrid systems. Dynamic kinetic models of chemical reactions are described by systems of ordinary differential equations (clear deterministic models), on the basis of which, using various optimization methods (least squares, etc.), the inverse problem of chemical kinetics is solved. B. Kosko proved that any mathematical system can be approximated as accurately as desired by a non-deterministic or weakly deterministic model based on fuzzy logic using simple algorithmic constructions of the “if ... then” type (conditional operators) without direct quantitative or qualitative analysis of systems of differential equations. A fuzzy kinetic model is an algorithmic design based on fuzzy algebra, which allows one to calculate the reaction rate for any values of reagent concentrations of interest to the experimenter. This model allows solving the inverse problem without a priori specifying the type of kinetic law, does not have an unambiguous formulaic representation and can be described by regression (clear) equations. In this article, based on fuzzy logic methods, regression kinetic models are obtained and studied to solve the inverse problem for a simple model reaction and the acetylene hydrochlorination reaction. It has been shown that clear regression models demonstrate good accuracy and can be used to establish alternative kinetic laws and mechanisms for chemical reactions.

Effects of ayahuasca on fear and anxiety: cross-talk between 5HT1A and 5HT2A receptors
Authors: Lopes Guerra Lorena Terene , dos Santos Rafael Guimarães , Cecilio Hallak Jaime Eduardo
Published: December 2024

Ayahuasca is a hallucinogenic substance currently being investigated for the treatment of mood, anxiety, and trauma-related disorders. Evidence from animal and human studies suggest that the effects of ayahuasca involve modulation of neural substrates relevant for emotional processing, especially in regions rich in serotonergic receptors. Moreover, preclinical studies also show that ayahuasca has specific effects on fear-related memories. The serotonergic system has been classically associated to anxiety and fear responses, with selective serotonin reuptake inhibitors being first-class medication to treat mood, anxiety, and stress-related disorders. Here we review currently available data regarding ayahuasca (and its main components) behavioral and functional effects on anxiety and fear-related responses through its modulation of serotoninergic signaling.

Published: December 2024

Objective: The primary objective of this study was to examine the educational damages faced by children of divorce. Divorce is a significant life event that imposes stress on the entire family, especially on children.

Methods: This study employed a systematic review of existing literature to identify key educational damages faced by children of divorce. A total of 3,296 articles were initially retrieved from databases, and through a rigorous selection process based on relevance, 27 studies were chosen for in-depth analysis. The indicators were categorized into 9 criteria using a coding framework, with each indicator representing a unique educational challenge or damage.

Findings: The review identified 72 educational indicators categorized into key themes such as academic decline, dropout rates, concentration and attention issues, cognitive development impairments, and reduced resources for education. The most frequent issues were poor academic performance, lack of concentration, and dropout rates. Children from divorced families exhibited significantly more challenges in school performance, motivation for achievement, and learning compared to those from intact families. The absence of a stable emotional and financial environment exacerbated these issues, further contributing to academic setbacks.

Conclusion: The findings highlight the severe impact of parental divorce on children's educational performance and mental well-being. Academic decline, lack of concentration, and emotional maladjustment are common issues, often leading to school dropout. Effective interventions, including parental education and structured support programs, are crucial to reducing the educational damages faced by children of divorce. Schools and counselors must be trained to address these challenges and work collaboratively with parents to create a supportive learning environment.

Authors: Ramezani Maryam , Mohammadi Akbar
Published: December 2024

Objective: This study aimed to compare the secretion of sexual hormones, executive brain functions, and changes in general health in women with and without premenstrual syndrome (PMS).

Methods and Materials: The research design was a causal-comparative method. The statistical population included all women who visited the health center in Zanjan in 2023. The sample consisted of 200 women with and without PMS, selected using purposive convenience sampling. The instruments used in this research included blood tests, a PMS assessment questionnaire, the Wisconsin Card Sorting Test for assessing executive brain functions, and a general health questionnaire. Data analysis was performed using independent t-tests and multivariate analysis of variance (MANOVA).

Findings: The findings indicated that the normal group had higher executive brain functions compared to those with PMS. Additionally, the general health of women with PMS was lower than that of the normal group. However, both groups exhibited the same level of progesterone hormone secretion, with no difference in the amount of progesterone secretion.

Conclusion: The study found that women with premenstrual syndrome (PMS) exhibited lower executive brain functions and general health compared to women without PMS. No significant differences were observed in estrogen and progesterone secretion levels between the two groups. These findings suggest that PMS negatively impacts cognitive functions and general health, highlighting the need for targeted interventions to improve the quality of life for affected women.

Authors: Elahifar Mohammad
Published: December 2024

Objective: The primary objective of this study was to examine the impact of women’s obsessive-compulsive disorder (OCD) symptoms and automatic thoughts on marital quality of life.

Methods and Materials: This cross-sectional study included 200 married women residing in District 7 of Tehran. The sample size was determined based on the Morgan and Krejcie table. Data were collected using three standardized tools: the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) for OCD symptoms, the Automatic Thoughts Questionnaire (ATQ), and the Quality of Marriage Index (QMI) for marital quality of life. Pearson correlation analysis and multiple linear regression were performed using SPSS-27 to assess the relationships between the independent variables (OCD symptoms and automatic thoughts) and the dependent variable (marital quality of life). Statistical significance was set at p < 0.05.

Findings: The results revealed a significant negative correlation between OCD symptoms and marital quality of life (r = -0.56, p = 0.003) and between automatic thoughts and marital quality of life (r = -0.62, p = 0.001). Multivariate regression analysis showed that both OCD symptoms (B = -0.42, p = 0.0002) and automatic thoughts (B = -0.56, p = 0.0001) were significant predictors of marital quality of life, accounting for 38% of the variance (R² = 0.38).

Conclusion: The findings indicate that OCD symptoms and negative automatic thoughts have a significant detrimental effect on marital quality of life. Automatic thoughts demonstrated a stronger negative influence than OCD symptoms. These results underscore the importance of addressing cognitive and psychological factors in therapeutic interventions aimed at improving marital satisfaction among women.

DIGITAL TRANSFORMATION AND BANK PERFORMANCE
Authors: Laras Pratiningsih  , Nurhastuty Kesuma Wardhani2
Published: December 2024

This study aims to investigate the effect of digitalization on bank profitability among Indonesian Banks. The research employs OLS on panel data of 50 banks in Indonesia during the period 2018–2022.The study reveals a positive impact of digitalization on bank profitability. The result is robust to different measures and empirical settings. Not surprisingly, small banks experience lower profitability than their peers. However, digitalization helps improve the profitability of these banks. This study explains the effect by showing that digitalization does not significantly reduce bank cost in terms of cost to income ratio and increases bank non-interest income through diversification into non-traditional products and services. In addition, the current stage of bank digitalization in Indonesia does not reduce banks’ employment costs since it requires staff to support and operate the new system. Practical implications – The research findings are motivations for bankers and policy-makers in designing appropriate strategies toward digitalization. Investors can also consider highly digitalized banks as valuable investments. This research extends the current literature on the relationship between digitalization and bank profitability, with a focus on commercial banks in Indonesia. Given the high involvement of the government and the dominance of several large banks in the banking system, the study also explores whether the effect of digitalization on bank profitability varies with the bank’s size. Last but not least, the channels in which digitalization affects bank profitability are also examined.

Published: December 2024

The research paper formulates a variable step block backward differentiation formula (VSBBDF) for solving nonlinear fuzzy differential equations (FDEs). Developed to address uncertainties within differential equations by using fuzzy environments, VSBBDF offers a flexible approach to solve equations with triangular fuzzy numbers. This method incorporates a dynamic step-size selection, allowing it to adapt to changes and reduce computational costs while maintaining accuracy. The paper further discusses the stability and convergence properties of VSBBDF, demonstrating that it is both zero-stable and of high accuracy. The results obtained highlight the method's computational efficiency and reliability, particularly when compared with other existing methods for solving nonlinear FDEs.
