Mesh Network for Railways
Authors: Shneps-Shneppe D M , Tikhonov E.O.
Published: January 2025

The possibilities provided by the mesh telecommunication network on the railways are examined in the article. Mobile terminal radio stations located on trains are considered as repeaters and moving base radio stations for trains outside the coverage area of base stations of the network. Such a mesh network is represented both as the main communication network on railway lines equipped with an insufficient number of radio base stations and as a backup option in the event of a base station failure on one hand or a decrease in the signaltonoise ratio at the terminal station due to a breakdown on the train on the other hand. The results of a theoretical mathematical calculation of the increase in the effective coverage area of a radio network gained from the use of mesh technology are presented. The results of modeling of the mesh network on the railroad are also presented together with the dependencies of the probability of communication from such factors as: the number of trains on the railway line, the number and range of the base stations, the range of terminal stations, the capacity of the network and the limitation on the number of retransmissions. For the case of using a mesh network as a backup option when a railway line is fully covered with base stations, the results of simulating the time of establishing a connection via a retransmission in the area of a base station failure are presented. Comparison of the possibilities provided by firstorder mesh networks (with one repeater between the terminal and base stations) and more capacious (second and higher orders by the number of allowable repeaters) is presented. As a radio communication standard for mesh network modeling, the application of DMR (Digital Mobile Radio) is considered as a promising one for railway communications, requiring a small number of base stations.

Published: January 2025

Суть предлагаемой статьи состоит в стремлении выявить основные смысловые горизонты той важнейшей части творческого наследия великого композитора, которую составляют его произведения для клавира. То, что мы обычно связываем с понятием семантика (нем. Semantik от греч. обозначающий), в данном случае сконцентрировано в пяти разделах центральной части материала (Festoso, Energetica, Sapiens, Dramatik, Universum), призванных дать представление о базовых составляющих образного мира, каким он заявлен в рассматриваемых сочинениях. Центральная часть статьи обрамлена аркой вступительного (Predict) и заключительного (Postict) разделов. Первый из них предваряет изложение панорамой жанров, второй содержит итоговые наблюдения. В своей сумме последовательность этих разделов обеспечивает достаточно полный охват определяющих смысловых аспектов клавирного искусства И. С. Баха.

The essence of the proposed article is the desire to identify the main semantic horizons of that most important part of the creative heritage of the great composer, which is his works for the clavier. What we usually associate with the concept of semantics (German Semantik from Greek denoting), in this case is concentrated in five sections of the central part of the material (Festoso, Energetica, Sapiens, Dramatik, Universum), designed to give an idea of the basic components of the figurative world, as it is stated in the works under consideration. The central part of the article is framed by an arch of the introductory (Predict) and final (Postict) sections. The first of them precedes the presentation with a panorama of genres, the second contains final observations. In its sum, the sequence of these sections provides a fairly complete coverage of the defining semantic aspects of J.S. Bach's clavier art.
МУЗЫКА ЛАТИНСКОЙ АМЕРИКИ: ИНДИХЕНИЗМ, НЕОФОЛЬКЛОРИЗМ, СТРАВИНСКИЙ
Authors: ДОЦЕНКО В Р.
Published: January 2025

В статье предлагается проследить исторический процесс образования индихенизма - специфического направления музыкального творчества, в котором отразилась наиболее примечательные черты мировосприятия жителей Латинской Америки. С XVI до начала XIX века музыкальная культура Латинской Америка находилась под подавляющим европейским влиянием. Формирование общественного сознания проходило на фоне процессов этно-культурного синтеза, в связи с чем в работе прослеживается эволюция взглядов на культуру индейцев от полного отрицания до признания ее образующей роли. К началу ХХ века музыкальная культура Латинской Америки обрела черты зрелости, свидетельством чему явилось возникновение множества значительных произведений, сконцентрировавших в себе такой сгусток национальной характерности, какого Латинская Америка ранее не знала. Пионером в отражении традиций мексиканских индейцев стал К. Чавес, «Индейская симфония» которого считается эталоном музыкального индихенизма. В творчестве латиноамериканских композиторов проявилась устойчивая тенденция к созданию произведений в русле неофольклоризма, в которых элементы европейской, индейской и афроамериканской музыки нашли органичное преломление. Мирового признания достигли такие композиторы как Э. Вилла Лобос, А. Хинастера, М. Нобри. Выдающийся вклад в становление неофольклоризма был сделан И. Стравинским, оказавшим решающее влияние на творчество композиторов Латинской Америки.

The article proposes to trace the historical process of formation of indigenism - a specific direction of musical creativity, which reflects the most remarkable features of the world perception of Latin Americans. From the sixteenth to the early nineteenth century, Latin American musical culture was overwhelmingly influenced by European influences. The formation of public consciousness took place against the background of the processes of ethno-cultural synthesis, in connection with which the work traces the evolution of views on Indian culture from complete denial to recognition of its formative role. By the beginning of the twentieth century, the musical culture of Latin America had reached maturity, as evidenced by the emergence of many significant works that concentrated in themselves a clot of national character, which Latin America had not previously known. The pioneer in reflecting the traditions of the Mexican Indians was C. Chavez, whose "Indian Symphony" is considered the standard of musical indigenism...
G. LIGETI’S WORK WITH SINGLE-TONE STRUCTURES
Authors: MOLCHANOV ANDREY S.
Published: January 2025

The article is devoted to the works of G. Ligeti of the 1950-1960s, which present the tendency of organising a composition by means of a single tone. The starting point is the question formulated by the composer: “What can I do with a single note?”, which he solves in different ways. In the earlier cycle of “Musica ricercata” Ligeti most strictly follows the chosen pitch, relies on repetitions of one tempered sound scattered over all octaves, applies a change in texture density, tempo, dynamics, register. In a later Concerto for Cello and Orchestra, the composer prefers the sonoristic interpretation of sound, its spatial form of presentation, timbre and articulation gradations. As a result, Ligeti overcomes the experimental context of using singletone sound structures, making them part of a meaningful sound concept aimed at discovering a rich microcosm of sound connections and relationships.

Published: January 2025

At the beginning of the last century, there were serious changes in music, whose full understanding became possible only after many years. The fundamentally new aesthetic category of style, reflecting the creative thinking of the early Russian avant-garde musicians, has determined the specifics of the entire musical era. With their experiments, the authors essentially predicted much of what developed further throughout the 20th century and the beginning of the 21st century. Behind this are the names of specific composers, whose work is now beginning to be explored in a new way in the art history field. One of them is M. Matyushin. The article reveals a new milestone in the actualisation of his work in the first quarter of the 21st century in Russia.
INGUISTIC REPRESENTATION OF MāORI WOMEN’S ETHNIC IDENTITY IN NEW ZEALAND MEDIA DISCOURSE: SEMANTIC MACRO-AREAS AND DISCURSIVE STRATEGIES
Authors: TRAVINA EKATERINA A.
Published: January 2025

The study examines the representation and construction of indigenous Māori women’s ethnic identity in contemporary New Zealand media, focusing on the main semantic macro-areas related to the discursive construction of aboriginal women’s ethnic identity and discursive strategies employed in 100 media texts from three New Zealand online media: The New Zealand Herald, E-Tangata, and Woman Magazine New Zealand. The study identifies two key semantic macro-areas related to the discursive construction of Māori women’s ethnic identity: the topic of the implications of Māori people colonisation and the topic of the revival of the traditional Māori culture. Two main groups of discursive strategies used for representation and construction of Māori women’s ethnic identity are identified and described: constructive and perpetuation strategies aimed at forming and maintaining a specific ethnic identity, and transformation strategies that facilitate changes in an ethnic identity.

Boosting Predictability: Towards Rapid Estimation of Organic Molecule Solubility
Authors: Hashemi Arsalan , Peljo Pekka , Ala-Nissila Tapio , Laasonen Kari
Published: January 2025

The water solubility of organic molecules is critical for optimizing the performance and stability of aqueous flow batteries, as well as for various other applications. Although relatively straightforward to measure in some cases, the theoretical prediction of the solubility remains a considerable challenge. To this end, machine learning algorithms have become increasingly important tools in the past decade. High-quality data and effective descriptors are essential for constructing reliable data-driven estimation models. We systematically investigate the effectiveness of enhanced structure-based descriptors and an outlier detection procedure for improving aqueous solubility predictability. We train and evaluate random forest regression models using various descriptors to predict experimental solubility. Outliers are identified through an iterative maximum-error deletion procedure. We discover that descriptors derived from hydration free energy and weighted fingerprints, along with other established features, are effective. Notably, solvation energy, octanol-water partition coefficient, atomic charge polarizability interactions, and the presence of a full-carbon aromatic ring are critical for solubility prediction. Furthermore, the effectiveness of the outlier detection protocol is validated by improving the performance of the model and detailed analysis of the dataset. This study significantly improves the predictive capacity of supervised machine learning for molecular properties, enabling advancements in various technological applications.
Giant Dipole Moments: Remarkable Effect of Single Solvent Molecules on 5, 6- Diaminobenzene-1,2,3,4-Tetracarbonnitrile
Authors: Stanley Katherine , Givhan R. Houston , Turney Justin , Schaefer III Henry F.
Published: January 2025

The molecule 5, 6- diaminobenzene-1,2,3,4-tetracarbonnitrile (MOI) was first synthesized by Müllen and coworkers in 2016, and boasts an ultrastrong dipole moment of $14.1\pm 0.7$ debye in THF. Gas phase DFT computations do not fully reflect this ultrastrong dipole moment, demonstrating the role of solvent in increasing this dipole. Here we investigate the effect of solvent molecule position on the dipole moment of this species, computationally examining systems with giant dipole moments. These systems are optimized in gas the phase with the B3LYP functional, employing the aug-cc-pVTZ and def2-TZVP basis sets, as well as the B3LYP-D3BJ/aug-cc-pVTZ functional in Orca. Single point DLPNO-CCSD/aug-cc-pVDZ results were obtained from Orca and Psi4, as well as DLPNO-CCSD(T)/CBS information from \textsc{Psi4}. These are additionally compared to the dipole moments predicted with SMD models at the B3LYP/aug-cc-pVTZ level of theory. The dissociation energy, HOMO-LUMO energy gaps, and dipole moments are presented. These metrics show the nh1nh1\emprime THF system (Figure \ref{THF Structures}.b) boasts the largest dissociation energy and dipole moment of the singly solvated systems, due to its strong hydrogen bonding. The importance of solvent placement is highlighted and may guide the synthesis of macromolecules or organic frameworks incorporating the MOI or MOI-like subunits. Remarkably, a single solvent molecule provides a good model for the difference between the gas phase and solvated species.
Nutritional support as a way to adjust the body's immune response: Experimental data and clinical studies. A review
Authors: Makhova Anna А. , Fedorova Tatiana A. , Shikh Evgenia V.
Published: January 2025

According to the World Health Organization, 2 billion people all over the world suffer from infectious diseases every year. Infectious diseases remain among the leading causes of death and the first cause of premature death despite the implementation of vaccination programs. Vitamins and micronutrients are essential in supporting both the cellular and humoral parts of the immune system (IS), increasing resistance to infections. Micronutrient deficiency is a recognized global public health problem, and hypovitaminosis and nutrient deficiency conditions predispose to infections. Micronutrients such as vitamins A, C, D, E, B2, B6, B12, folic acid, selenium, zinc, and iron are necessary to maintain immunocompetency. Both in adulthood and in old age, patients have an increased risk of occurrence and severity of infections due to the high prevalence of hypovitaminosis, a decrease in the function of the IS, and the presence of comorbidities. Nutritional support by vitamin and mineral complexes (VMC) with rational composition is a strategy to correct the immune response. VMCs should complement a healthy diet and contain micronutrients within the recommended amounts at the level of daily food requirement. It is advisable to use a differentiated approach to VMCs to modulate the IS function. Basic nutritional support with vitamins C, D, and zinc is most often sufficient for people without the risks of severe and complicated acute respiratory infections. Various mechanisms of action and different targets of micronutrients that correct the body's immune response and synergistic interactions support the discussion of the hypothesis of a more pronounced effect of multicomponent VMCs. In the presence of chronic diseases, in the case of comorbidity, it is advisable to use expanded formulation VMCs containing, in addition to vitamins C, D, and zinc, other micronutrients, such as vitamins A, E, B, copper, selenium, which helps reduce the risk of severe course and complications of respiratory infections in at-risk groups.

Authors: Kosenko Viktor , Tymokha Denys , Kosenko Alisa
Published: January 2025

The paper is dedicated to rethinking European immigration waves and drawing conclusions for the modernization and corporatization of large state-owned enterprises in Ukraine. This is significant for developing effective strategies for integrating migrants, enhancing management transparency, and ensuring sustainable economic development in Ukraine, as well as for implementing European practices and developing new digitalized Ukrainian practices of transparency and accountability in managing state-owned enterprises. The article begins with a review of the European experience of two immigration waves over the past 30 years, which created “immigration shocks” and contributed to a sharp increase in public attention to immigration issues, as well as structuring political competition on both the supply and demand sides of democratic representation. Based on this, the author’s vision is proposed on how this European experience can be applied to the not very popular among scholars and politicians in Ukraine and the EU, but economically significant for Ukraine, theme of promoting broad modernization of Ukrainian society and, in particular, supporting the corporatization of large state-owned enterprises, such as JSC “Ukrzaliznytsia”. The conclusion is made that state-owned corporations in Ukraine, facing a shortage of labor due to war and migration, can adapt the EU’s experience in managing migration to solve their staffing problems: a) develop targeted programs to attract qualified personnel from abroad, including the Ukrainian diaspora; b) create attractive working conditions and social packages to retain existing employees and attract new ones; c) invest in training and qualification improvement programs for local employees; d) implement more automation and digitalization processes to reduce dependence on manual labor; e) cooperate with the government to develop special visa programs for attracting foreign specialists in critically important sectors.
Regulatory and Legal Ways to Resolve Existing Conflicts in the Field of Cyber Security in the Context of the Creation of Cyber Forces of the Armed Forces of Ukraine
Authors: Zhyvylo Yevhen , Dokil Valentyn
Published: January 2025

The current proliferation and commercialization of cyber attack tools has changed the balance of power in cyberspace and allowed a wide range of actors to use cyber tools for geopolitical influence and economic gain. The applicable tools, which can be freely used, provide unprecedented opportunities for espionage, fraud and hacking, the use of which is aimed at financial gain, disruption of the sustainable functioning of critical infrastructure facilities and various forms of ownership of electronic communication systems and networks.The dynamics of the current situation regarding the ability to buy ready-made hardware and software solutions and create individual cyber tools continues to “challenge” national security, the commercial sector and the civilian population.By increasing the ability to acquire cyber tools on a commercial basis, both state and non-state actors can quickly move from new threats to existing ones, so this leap is seen as a key factor in the cyber defense landscape. In the future, this can lead to a high level of geopolitical instability in conflicts that will be more difficult to predict than traditional military changes in the balance of power.Under these conditions, an important task for Ukraine is to create conditions for protecting sovereignty and ensuring the defense capability of the state in cyberspace by supporting the capabilities of the defense forces to carry out active cyber protection of its own information infrastructure and preparing the state to repel military aggression in cyberspace both in peacetime and in a state of war (a special period ).In view of the above, this paper analyzes the current regulatory legal acts of the state regarding the implementation of relevant tasks by cyber security entities within the framework of state cyber defense and national cyber defense measures with the aim of delimiting powers, establishing responsibility for specific areas of activity and implementing priority tasks in this field.
Ethical model of management: a conceptual approach
Authors: Shtyrov Oleksandr
Published: January 2025

The article is devoted to the question of the role of ethical management, which is proposed to be implemented in the format of a model. Because ethical management is conceived by the author as a dynamic and continuous process that needs to adapt to the changing internal and external context of the organization, such as industry, market, stakeholders, culture and values. Ethical governance benefits organizations by improving reputation, trust, loyalty, productivity and profitability, and by avoiding legal, regulatory and reputational risks. It is emphasized that ethical management can be implemented in the form of a model. In turn, an ethical management model requires awareness, commitment and action from all levels of the organization, especially top management. The author states that in order for the ethical model of management to become effective, it must first be guided by a certain set of criteria (components) that must be followed so that management within the organization and its development takes place in line with ethical principles and principles. The following are highlighted among them: honesty, integrity, justice, kindness, legality, perfection, leadership and responsibility. It is shown that conceptually ethical management can be implemented through a number of approaches. In particular, this traditional approach involves the implementation through society's perception of management as an ethical category, under the conditions of performance of the assigned tasks by the team without going beyond the framework of ethical norms and standards. A principled approach is based on the use of ethical criteria to guide behavior, actions and policies in an organization. The approach to the survey in the field of ethical regulation is based on short practical questions that regulate the behavior and process of ethical decision-making in the organization.
It is concluded that each individual brings his own ethical profile to the workplace and is ultimately responsible for his actions or decisions from an ethical point of view. However, organizations can and do influence the quality of ethical decisions made by their leaders, managers, and employees, as well as the ethical principles they adhere to and refer to when making these decisions, thereby implementing ethical governance at work.

The article substantiates the need for transformations of the government policy of electronic healthcare and medicine. The purpose of the article is to determine ways of further reforming electronic health care and providing electronic medical services in Ukraine based on the analysis of the current state of health care. Based on a study of the international experience of assessing the state of the health care sector (The Health Care Index, Global Health Security Index, Global Digital Health Index, Global Digital Health Monitor), it was determined that the health care sector of Ukraine is experiencing rapid growth, focusing on the development of such tools of the government mechanism for the e-health’s development such as health monitoring and organizational support for the provision of medical services. The directions of the government reform of e-health in Ukraine and the possibilities of using e-tools in medicine, medical services in conditions of war are analyzed. It has been proven that the widespread use of electronic tools, the use of medical information to monitor the health of the population and manage the work of the health care system of Ukraine allow for a flexible and quick response to situational management decisions, which determines the importance and necessity of the development of e-health. Under such conditions, the priority direction of the government policy of Ukraine in the field of health care is the further development of e-health, which has great potential for the sustainable development of the country and further European integration.
Development of a system of measures regarding inclusion at the local level
Authors: Bondarenko Lesia
Published: January 2025

The development of a system of measures for inclusion at the local level is considered as an urgent problem with the beginning of a full-scale invasion of Russia. The problem of inclusion and adaptation of internally displaced persons in our country in the conditions of hostilities has been identified. According to the results of the study, it was noted that during this period more than 1.5 million Ukrainians were forced to leave their homes. It is emphasized that in the conditions of the armed conflict on the territory of our country, the importance of the problem of inclusion and adaptation of internally displaced persons (IDPs) in local communities in new territories is increasing significantly.
A theoretical generalization of the features of the implementation of the system of inclusion measures at the local level in Ukraine was carried out, taking into account the specifics of urban and rural areas and their inclusiveness. In the modern approach to the construction and implementation of a system of inclusion measures at the local level in Ukraine under martial law, the following should be taken into account: adaptability to unforeseen situations, ensuring security and stability, involvement of the local community.
The article examines the peculiarities of functioning and the main directions of development of the system of inclusion measures at the local level, taking into account the modern point of view. The components of the system of inclusion measures at the local level (functional components, tools and principles), as well as the peculiarities of their interrelationship, are substantiated. The identified principles can serve as a basis for effective public management of system development regarding inclusion at the local level, balance and interaction between state bodies, local self-government bodies and the public.
Non-flat Friedmann-Lemaitre-Robertson-Walker universe with Barrow holographic dark energy
Authors: Mahanta Chandra Rekha , Medhi Joy Prakash , Mahanta Rajashree
Published: January 2025

In this paper, we study a non-flat Friedmann-Lemaitre-Robertson-Walker (FLRW) universe filled with cold dark matter and Barrow holographic dark energy. We assume the Hubble horizon as IR cutoff and the scale factor to obey a hybrid expansion law to construct a cosmological model within the framework of General Relativity. The physical and geometrical properties of the model are discussed by studying the evolution of various parameters of cosmological importance. The behaviour of the dark energy equation of state parameter  wDE is also studied for both interacting and non-interacting Barrow holographic dark energy. We observe that the Barrow exponent ∆ significantly affects the dark energy equation of state parameter which in turn exhibits the behaviour of quintessence and phantom dark energy. The evolution of the jerk parameter is also studied.
Numerical Investigation of the Squeezing Flow of Ternary Hybrid Nanofluid (Cu-Al2O3-TiO2/H2O Between Two Parallel Plates in a Darcy Porous Medium with Viscous Dissipation and Heat Source
Authors: Bora Rubul , Boruah Bidyut
Published: January 2025

This work aims to investigate numerically the influence of viscous dissipation and heat source on the magnetohydrodynamics squeezing flow of water-based ternary hybrid nanofluids between two parallel plates in a Darcy porous medium. The nanoparticles Cu, Al2O3, and TiO2 are dispersed in a base fluid H2O, resulting in the creation of a ternary hybrid nanofluid Cu-Al2O3-TiO2-H2O. This study examines the deformation of the lower plate as the upper one advances towards it. The numerical results are computed using the 3-stage Lobatto IIIa method, which is specially implemented by Bvp4c in MATLAB. The effects of various parameters are visually illustrated through graphs and quantitatively shown in tables. The absolute skin friction of the ternary hybrid nanofluid is seen to be approximately 5% higher than that of the regular nanofluid at the lower plate and at most 7% higher than that of the nanofluid at the upper plate. The heat transmission rate of the ternary hybrid nanofluid is higher at the upper plate compared to the lower plate.
Thermal Performance of Nanofluid Flow Along an Isothermal Vertical Plate with Velocity, Thermal, and Concentration Slip Boundary Conditions Employing Buongiorno’s Revised Non-Homogeneous Model
Authors: Mishra Sujit , Pati Aditya Kumar , Misra Ashok , Mishra Saroj Kumar
Published: January 2025

This study examines the natural convection of a steady laminar nanofluid flow past an isothermal vertical plate with slip boundary conditions. A review of existing literature reveals no prior research that has explored the combined effects of thermophoresis, Brownian diffusion, and particle electrification while considering slip boundary conditions in nanofluid flow. Buongiorno’s revised four-equation non-homogeneous model, incorporating mechanisms for thermophoresis, Brownian diffusion and particle electrification, is utilized to address this gap. The model employs velocity, thermal, and concentration slip boundary conditions to investigate enhancing the nanofluid's thermal conductivity. The resulting local similar equations are tackled using MATLAB's bvp4c package. The study discusses the influence of key parameters, such as thermophoresis, Brownian motion, and electrification, on temperature, velocity, and concentration distributions, as well as on heat, mass transfer and skin friction coefficients. The findings of the simulation are consistent with previous studies, showing that an improvement in the electrification parameter rises the heat transfer coefficient, while thermophoresis and Brownian motion parameters have the opposite effect. Additionally, mass transfer coefficient values increase with higher Brownian motion and electrification parameters while reducing with the thermophoresis parameter. This physical model has potential applications in heat exchangers using nanofluids and in cooling plate-shaped products during manufacturing processes. The novelty of this study lies in the analysis of Brownian diffusion, thermophoresis, and particle electrification mechanisms in nanofluid flow under slip boundary conditions.

Authors: Vijaya Sree R. , Narla V. K. , Babu K. Suresh
Published: January 2025

The present study investigates the dynamics of a biomagnetic couple stress fluid within an anisotropic porous channel where the channel walls are stretchable. This study examines the flow behavior under the influence of an external magnetic field generated by a magnetic dipole. Appropriate dimensionless parameters are introduced to simplify the equations of the problem. A suitable numerical approach based on the Spectral Quasi-Linearization Method is utilized to obtain a solution to the problem. In this work, influence of several important parameters like the anisotropic permeability ratio, couple stress parameter, anisotropic angle, Darcy number, ferromagnetic interaction parameter, Reynolds number, and Prandtl number are examined. The results indicate that ferromagnetic interaction parameter and couple stress parameter significantly impact heat transfer and fluid flow. Permeability ratio and angle also affect the flow dynamics. Furthermore, the coefficient of skin friction and rate of heat transfer were examined, varying the couple stress and ferromagnetic interaction parameters. The findings demonstrate that an existence of magnetic dipole and anisotropic permeability significantly influences the flow and thermal properties of ferrofluids, providing valuable insights for optimizing heat transfer and controlling fluid flow in diverse engineering and medical applications.

Authors: Tarakaramu Nainaru , Kumar B. Jagadeesh
Published: January 2025

There are extensive range of applications related to nuclear industry, industrial manufacturing, science and engineering processing, in which the boundary layer hydromagnetic motion of Casson liquids perform vital role. Casson liquid is a useful liquid in the nuclear industry for optimizing the design and operation of nuclear reactors. Researchers have investigated transfer of heat in liquid motions with linear stratification, which is a phenomenon where the temperature varies linearly with height, affecting various fields such as medical equipment, glass fiber production, electronic devices, polymer sheets, paper production, filaments, and medicine. However, the most discussion of heat transfer problems is to get numerical solutions of a comprehensive Casson liquid model with heat generation described by the BVP4 via shooting method. In this study, a new velocity slip boundary condition is applied at the stretching or shrinking surface. These conditions are grounded in the previously established Buongiorno model, providing a more practical and realistic approach compared to previous study. The time independent Gov. Eqs. changed into a set of couple non-linear ODEs with help of suitable similarity conversions. The equations are evaluating via R-K-F by help of MATLAB software programming.

Published: January 2025

Molecular docking and molecular dynamics methodologies were employed to design and evaluate delivery systems for the antineoplastic agent doxorubicin (DOX) utilizing human serum albumin (HSA) as the carrier. To engineer a drug delivery system (DDS) with dual imaging modalities, complexes of the radionuclide technetium-99m (TCC) and near-infrared (NIR) fluorescent dyes, including indocyanine green (IG), methylene blue (MB), heptamethine cyanine dye AK7-5, and squaraine dye SQ1, were integrated into the protein nanocarriers. The highest binding affinities to the proteins were identified for TCC [99mTc]Tc-diisopropyl iminodiacetic acid (TcDIS), [99mTc]Tc-hydrazinonicotinic acid-H6F (TcHYN), [99mTc]Tc-Mebrofenin (TcMEB), as well as the fluorescent dyes IG and SQ1. Molecular docking analyses revealed that most technetium complexes (TCCs) bind to HSA domain I, with some exceptions showing affinity for domains I and III or domain III alone. Ternary and quaternary protein-ligand systems were explored using multiple ligand docking approaches. In ternary systems, DOX binding sites were identified either in domain I or in a region spanning multiple domains, depending on potential overlap with TCC binding sites. For quaternary systems incorporating NIR fluorophores, binding affinities decreased in the order: IG > SQ1 > AK7-5 > MB. Molecular dynamics simulations of HSA-DOX-MB and HSA-DOX-IG complexes demonstrated stable associations between the components, with consistent center-of-mass distances and minimal perturbation of HSA structure. These findings support the potential of HSA as a suitable carrier for developing dual-modality imaging nanocarriers incorporating both radionuclide and fluorescence imaging capabilities.

Förster resonance energy transfer (FRET) between the membrane fluorescent probes pyrene and TDV was employed to investigate the modulation of amyloid-lipid interactions by polyphenols. The effects of various polyphenols, including quercetin, curcumin, gallic and salicylic acids, on the complexation between the amyloid fibrils derived from N-terminal fragment of apolipoprotein A-I (ApoA-IF) and insulin (InsF), and liposomes composed of phosphatidylcholine (PC) and its mixtures with cardiolipin (CL), cholesterol (Chol), or phosphatidylglycerol (PG) were investigated. The incorporation of polyphenols resulted in decreased energy transfer efficiency, indicating a significant alteration in the spatial relationship between amyloid fibrils and lipid membranes. The magnitude of this effect was found to be dependent on lipid bilayer composition, the chemical nature of the polyphenols, and the type of amyloidogenic protein. Notably, curcumin exhibited the most pronounced impact across all systems, with a particularly strong effect on ApoA-IF compared to InsF. This differential response suggests protein-specific mechanisms of interaction and highlights the potential for targeted therapeutic approaches. Our findings provide novel insights into the intricate interplay between polyphenols, amyloid fibrils, and lipid membranes, contributing to the fundamental understanding of amyloid-related pathologies and opening new avenues for the development of polyphenol-based therapeutic strategies in amyloid-associated disorders.

Islam adalah agama yang dikenal memuliakan perempuan. Namun, ditemukan riwayat hadis yang secara tekstual tampak masih ada diskriminasi atau bias gender dalam pendidikan. Ini sepintas lalu tampak berseberangan dengan visi pendidikan Islam yang hendak menyamaratakan pendidikan tanpa memandang gender. Ditambah, secara filosofis, pendidikan adalah hak bagi setiap individu tanpa memandang gender. Tujuan kajian ini adalah mengoleksi hadis-hadis yang berkaitan dengan pendidikan perempuan, kemudian memahami dan menganalisis hadis-hadis tersebut dengan pendekatan tematik dan filosofis. Penelitian ini menggunakan metode analisis konten dan analisis deskriptif dalam mengkaji hadis-hadis yang berkaitan dengan pendidikan perempuan. Pisau analisis yang diterapkan adalah pendekatan analisis filsafat pendidikan Islam yang diusung oleh Seyyed Hossein Nasr. Hasil kajian menunjukkan bahwa pendidikan perempuan adalah sebuah peradaban baru yang dibangun oleh Nabi Muhammad yang bisa diketahui lewat hadis-hadis terkait pendidikan perempuan. Tidak ada diskriminasi gender tertentu dalam pendidikan sebagai peradaban baru yang sedang dibangun.
