SALT-FREE DYEING - A NEW METHOD OF DYEING ON LYOCELL/COTTON BLENDED FABRICS WITH REACTIVE DYES
Authors: Periyasamy Aravin Prince , Dhurai Bhaarathi , Thangamani K.
Published: December 2023

Cellulosic/regenerated blended fabrics dyed with reactive dyes require a large amount of salt, which pollutes fresh watercourses. Due to the hydrolysis of the dye, the dyeing effluent consists of a large amount of hydrolysed dye, and it requires a high volume of water to remove the hydrolysed dye in a wash-off process. Lyocell/cotton fabrics were dyed with reactive dyes using conventional methods and pretreating the fabric with polyvinylamine chloride (at five different concentrations). Pretreated samples were dyed without using salt as an electrolyte. The influence of pretreatment on K/S value, wash fastness, rubbing fastness, tensile strength, flexural rigidity and crease recovery were determined. It was found that pretreatment of Lyocell/cotton fabrics with polyvinylamine chloride increases dye uptake and shows good wash fastness and rubbing fastness. There was a slight increase in crease recovery angle and flexural rigidity in the pretreated sample. It was determined that polyvinylamine chloride was found to be effective for pretreatment in salt-free dyeing of Lyocell/cotton fabrics.
TOPOGRAPHICAL EFFECTS OF O2- AND NH3-PLASMA TREATMENT ON WOVEN PLAIN POLYESTER FABRIC IN ADJUSTING HYDROPHILICITY
Authors: Calvimontes Alfredo , Saha Rajib , Dutschk Victoria
Published: December 2023

Hydrophilisation of polyester textile materials has been investigated over the last twenty years using low-pressure and atmospheric plasmas. According to these studies, wettability and capillarity of fabrics can be significantly improved depending on the process gas used. In the present study, the effects of low pressure O2- and NH3- plasma on the morphology and topometry of fabrics on four different length scales, as well as the influence of the topographical changes of textile structures on the resulting water spreading and absorption rates were investigated. The results of the topographic characterisation using two non-contact optical methods and wettability measurements indicate that the modification of filament nano-topography cannot satisfactorily explain the drastic changes observed in wettability. Dimensional changes (relaxation and shrinkage) as well as changes in warp morphology and inter-yarn spaces are more decisive for inducing hydrophilicity in polyester woven plain fabrics than an increase in the surface nano-roughness of their filaments.
STUDY OF HEAT TRANSFER THROUGH MULTILAYER CLOTHING ASSEMBLIES: A THEORETICAL PREDICTION
Authors: Das Apurba , Alagirusamy Ramasamy , Kumar Pavan
Published: December 2023

Abstract

It has long been recognised that heat transfer through clothing is a main constraint to the comfort properties of
clothing. The present work relates to the development of a mathematical model for the prediction of heat
transmission through multilayer clothing with air in between two successive layers of fabric in a multilayered
clothing assembly. A mathematical model was developed using general equations of heat transfer through
porous media and was validated using experimental results. A series of multilayered fabric assemblies were
created with different combinations of fabric layers and air gaps of different thicknesses. The predicted total
thermal resistance of these fabric assemblies was obtained from the model and the values were compared with
experimental results. The total thermal resistance of these fabric assemblies were measured using a guarded
hot plate for validating the model. Fairly good correlations between the predicted and experimental values of
thermal resistance were observed.
NEW METHOD OF DISCHARGE PRINTING ON COTTON FABRICS USING HORSERADISH PEROXIDASE
Authors: Karthikeyan K. , Dhurai Bhaarathi
Published: December 2023

Abstract

Textile discharge printing is the most versatile and important of the methods used for introducing design to textile
fabrics. In discharge styles, the pattern is produced by the chemical destruction of the original dye in the printed
areas. The discharging agents used can be oxidising or reducing agents, acids, alkalis and various salts.
However, the most important methods of discharging are based formaldehyde sulphoxylates and thiourea
dioxide. Recently, environmental and industrial safety concerns have increased the potential for the use of
enzymes in textile processing to ensure eco-friendly production. Formaldehyde sulphoxylate
(NaHSO2.CH2O.2H2O) is one of the most powerful discharging agents; however, it is quite toxic and produces
formaldehyde, a known human carcinogen associated with nasal sinus cancer and nasopharyngeal cancer. In
this work, a hazardous chemical has been replaced with eco-friendly horseradish peroxidase enzyme in textile
discharge printing. Enzymatic discharge printing was carried out with a phenol oxidising enzyme system such
that the reactive dye was selectively discharged from the cotton fabric in selected areas, creating a printed
surface. The effects of enzyme concentration, pH of the printing paste, treatment time and the temperature of
enzymatic treatment were studied. The optimum conditions for enzymatic discharge printing were found to be
pH 8.5 at 70°C with a dye concentration of 80 g/L and 60 min as the treatment time.
NEW THICKENING AGENT BASED ON ALOE VERA GEL FOR DISPERSE PRINTING OF POLYESTER
Authors: El-Zairy Enas M. R.
Published: December 2023

Abstract

The technical feasibility of using Aloe vera gel as a new thickener for printing polyester with disperse dyes was
examined. The results indicate that the properties of the printed fabric samples (colour strength, K/S, overall
fastness properties, handling and sharpness) were dependent on gel concentration, the type and concentration
of additive (i.e. urea or citric acid), as well as the fixation conditions using the super-heated steam technique. The
optimum conditions for printing polyester fibre with disperse dyes using Aloe vera gel as a thickener were as
follows: 30 g/kg disperse dye, 50 g/kg urea, 15 g/kg citric acid, 500 g/kg Aloe vera thickener and 50% drying at
100°C for 3 min followed by steam fixation for 6 min at 180°C.
Typological shift of Mandarin Chinese in terms of motion verb lexicalization pattern
Authors: Linjun Liu , Yingxin He
Published: December 2023

Given the controversies over Mandarin Chinese in terms of Talmy’s bipartite language typology, this paper presents an exhaustive study of Chinese motion verbs collected from two authoritative dictionaries, namely, The Ancient Chinese Dictionary (2nd Edition) and The Contemporary Chinese Dictionary (7th Edition). An analysis of 662 motion verbs in ancient Chinese and 693 motion verbs in modern Chinese indicates that Mandarin Chinese has undergone a typological shift from verb-framed to satellite-framed as far as the lexicalization pattern is concerned. The typological shift seems to have been driven by two forces, the decline of monosyllabic motion verbs and the upsurge of disyllabic motion verbs, which, upon second thoughts, can be boiled down to a single but predominant process of disyllabification in Chinese, whereby two (former) roots that bear a wide range of syntactic relations are lexicalized into a disyllabic word. Thus, we see an intriguing case of how phonology and morphosyntax interact to impact the typological properties of a language.
Indentation creep in polymers and polymer nanocomposites
Authors: Flores Araceli
Published: December 2023

Creep refers to the capacity of a material to bear load and it represents a fundamental property for material design. Indentation appears as a most convenient tool for the study of creep behavior in polymers. The present work gathers information on the indentation creep response of a wide variety of polymers, taken from different sources, and offers a comprehensive overview of the factors that can influence creep. It is shown that viscoplastic behavior assessed by the traditional technique is influenced by the internal polymer characteristics and also by external factors. As a general rule, chain stiffness, chain branching, crystallinity, physical ageing and rigid-filler addition promote creep resistance. The advent of modern instrumented indenters allowed analysis of viscoelastic flow. Interestingly, it is found that the creep parameters obtained from traditional and instrumented testing are in close agreement provided the viscoplastic regime prevails. Graphene-polymer nanocomposites are used to illustrate the reduced creep rate, creep extent and strain rate sensitivity found upon addition of the rigid filler to a number of thermoplastic matrices.

Authors: Ross Jeremy A. , Jelmini Jacob D. , Leary Brian K. , Hoch Matthew C. , Heebner Nicholas R.
Published: December 2023

Extended overreaching without recovery carries risks of nonfunctional overreaching and overtraining. Coaches mitigate these risks by screening for overreaching, often using jump testing; however, many are uncertain about which jump variables to measure. A systematic review was conducted to identify jumping kinetic and kinematic variables associated with heightened training stress. Manuscripts were included if they monitored overreaching in healthy, adult athletes at National Level or above using an unloaded vertical jump test; and excluded if they did not report measured kinetic/kinematic variables, did not include sufficient data to calculate effect sizes (ES) and confidence intervals (95% CI) or were not available in English. Fourteen manuscripts met inclusion/exclusion criteria. Most studies had a low (71.4%) or moderate (21.4%) risk of bias. Twenty-nine unique outcome measures were reported with 11 reported in multiple studies. The most reported measures were the ratio of flight time to contraction time (15 ES reported), jump height (JH, 12 ES), mean power (7 ES), peak power (PP, 7 ES), mean velocity (5 ES), and peak force (PF, 5 ES). PP, PF, and JH demonstrated the most consistent negative alterations. Coaches should consider metrics that include changes in jump strategy alongside JH in jump screening.

Tlr4Deletion Modulates Cytokine and Extracellular Matrix Expression in Chronic Spinal Cord Injury, Leading to Improved Secondary Damage and Functional Recovery

Published: December 2023

Toll-like receptors (TLRs) play an important role in the innate immune response after CNS injury. Although TLR4 is one of the best characterized, its role in chronic stages after spinal cord injury (SCI) is not well understood. We examined the role of TLR4 signaling in injury-induced responses at 1 d, 7 d, and 8 weeks after spinal cord contusion injury in adult female TLR4 null and wild-type mice. Analyses include secondary damage, a range of transcriptome and protein analyses of inflammatory, cell death, and extracellular matrix (ECM) molecules, as well as immune cell infiltration and changes in axonal sprouting and locomotor recovery. Lack of TLR4 signaling results in reduced neuronal and myelin loss, reduced activation of NFκB, and decreased expression of inflammatory cytokines and necroptotic cell death pathway at a late time point (8 weeks) after injury. TLR4 null mice also showed reduction of scar-related ECM molecules at 8 weeks after SCI, accompanied by increase in ECM molecules associated with perineuronal nets, increased sprouting of serotonergic fibers, and improved locomotor recovery. These findings reveal novel effects of TLR4 signaling in chronic SCI. We show that TLR4 influences inflammation, cell death, and ECM deposition at late-stage post-injury when secondary injury processes are normally considered to be over. This highlights the potential for late-stage targeting of TLR4 as a potential therapy for chronic SCI.

Published: December 2023

Neurodevelopmental disorders (NDDs) are a group of complex neurologic and psychiatric disorders. Functional and molecular imaging techniques, such as resting-state functional magnetic resonance imaging (rs-fMRI) and positron emission tomography (PET), can be used to measure network activity noninvasively and longitudinally during maturation in both humans and rodent models. Here, we review the current knowledge on rs-fMRI and PET biomarkers in the study of normal and abnormal neurodevelopment, including intellectual disability (ID; with/without epilepsy), autism spectrum disorder (ASD), and attention deficit hyperactivity disorder (ADHD), in humans and rodent models from birth until adulthood, and evaluate the cross-species translational value of the imaging biomarkers. To date, only a few isolated studies have used rs-fMRI or PET to study (abnormal) neurodevelopment in rodents during infancy, the critical period of neurodevelopment. Further work to explore the feasibility of performing functional imaging studies in infant rodent models is essential, as rs-fMRI and PET imaging in transgenic rodent models of NDDs are powerful techniques for studying disease pathogenesis, developing noninvasive preclinical imaging biomarkers of neurodevelopmental dysfunction, and evaluating treatment-response in disease-specific models.

Published: December 2023

The long noncoding RNA (lncRNA) AUXIN‐REGULATED PROMOTER LOOP (APOLO) recognizes a subset of target loci across the Arabidopsis thaliana genome by forming RNA–DNA hybrids (R‐loops) and modulating local three‐dimensional chromatin conformation. Here, we show that APOLO regulates shade avoidance syndrome by dynamically modulating expression of key factors. In response to far‐red (FR) light, expression of APOLO anti‐correlates with that of its target BRANCHED1 (BRC1), a master regulator of shoot branching in Arabidopsis thaliana. APOLO deregulation results in BRC1 transcriptional repression and an increase in the number of branches. Accumulation of APOLO transcription fine‐tunes the formation of a repressive chromatin loop encompassing the BRC1 promoter, which normally occurs only in leaves and in a late response to far‐red light treatment in axillary buds. In addition, our data reveal that APOLO participates in leaf hyponasty, in agreement with its previously reported role in the control of auxin homeostasis through direct modulation of auxin synthesis gene YUCCA2, and auxin efflux genes PID and WAG2. We show that direct application of APOLO RNA to leaves results in a rapid increase in auxin signaling that is associated with changes in the plant response to far‐red light. Collectively, our data support the view that lncRNAs coordinate shade avoidance syndrome in A. thaliana, and reveal their potential as exogenous bioactive molecules. Deploying exogenous RNAs that modulate plant–environment interactions may therefore become a new tool for sustainable agriculture.

Published: December 2023

According to the Energy Strategy of Ukraine, the development of renewable energy sources (RES) is expected to be the most dynamic compared to other types of generation. However, the existing energy problems and threats require the development of new and amendment of existing legislative and by-laws, as well as a number of sectoral norms regulat-ing activities in the energy sector. The article provides an overview of the world's current trends in renewable energy, as well as the formation of areas that should be focused on when reforming the energy sector. The long-term energy policy of the state should be focused on the effective integration of RES into the power supply system. To this end, it is necessary to stimulate and control the implementation of distributed power generation management systems, virtual power plants, and energy storage systems. The gradual growth of electric vehicles leads to the use of Vehicle-to-Grid technology, especially when considering modern microgrids or "smart grids" with RES. And the concept of an "active building" is a key step towards decarbonizing the construction sector. Ref. 9, fig. 2.

The market operation of the electricity distribution system has gained significant expansion due to the growing use of renewable and distributed sources. This paper presents strategies for optimizing load schedules by aggregators of local systems. Optimization of load schedules is to minimize the total costs of the supplier to reduce the cost of electricity and lower prices for the consumer. In local systems, which include diesel generators, the main component that most affects the price per 1 kW is the consumption of primary fuel of diesel generators. The objective function proposed in this study minimizes the supplier's primary fuel consumption by optimally redistributing power to each generator. The basic load schedule and application of schedule optimization strategies were studied: load reduction, load transfer, increase of minimum loads, flexible load change. When using the optimal algorithm, the costs are 5-6% relative to the uniform power distribution. Ref. 8, fig. 4, table. Key words: local system, diesel-generator, load schedule, aggregator.

The gas-detonation technique was used for the synthesis of biocompatible hydroxylapatite-based protective coatings on polymer and titanium substrates. Hydroxylapatite powder of high purity with a grain diameter of 50 µm was used as the raw material. The obtained coatings have the thickness close to 200 µm. It has been shown that the offered method enables to create of non-destructive hydroxylapatite-based coatings on polymer by varying the distance between the polymer target and the gun nozzle of gas- detonation setup. Using the data of Raman and X-ray measurements, it was ascertained that gas-detonation deposition doesn’t change the composition of the deposited material. The SEM investigation testifies that the formed hydroxylapatite-based coatings are porous. EPR studies have shown that there are no paramagnetic defects in the obtained coatings, and the coating itself has a higher radiation hardness as compared to the raw powder.

Vanadium oxide (VO x ) thin films are promising materials, exhibiting electrical, optical, and mechanical properties highly tunable by processing and structure. This work uniquely applying atomic force microscopy (AFM) nanoindentation correlated with X-ray diffractometry and Raman spectroscopy structural analysis to investigate the intricate connections between VO x post-annealing, phase composition, and resulting nanoscale mechanical functionality. Utilizing an ultra-sharp diamond tip as a nanoscale indenter, indentation is performed on VO x films with systematic variations in structure – from mixed insulating oxides to VO 2 -dominated films. Analytical modeling enables extraction of hardness and elastic modulus with nanoscale resolution. Dramatic mechanical property variations are observed between compositions, with order-of-magnitude increases in hardness and elastic modulus for the VO 2 -rich films versus insulating oxides. Ion implantation further enhances nanomechanical performance through targeted defect engineering. Correlating indentation-derived trends with detailed structural and morphological characterization elucidates explicit structure-property relationships inaccessible by other techniques. The approach provides critical mechanics-driven insights into links between VO x synthesis, structure evolution, and property development. Broader implementation will accelerate processing optimization for electronics and advanced fundamental understanding of nanoscale structure-functionality relationships

Clorine doped CdTe single crystals (CdTe:Cl) were grown by the traveling heater method. MoO x /CdTe:Cl/MoO x films were deposited using the reactive magnetron sputtering technique. The defect structure of the obtained single crystals and heterostructures was investigated using high-resolution X-ray diffractometry. The optimized models of dislocation systems in the CdTe:Cl single crystals were constructed based on the Thompson tetrahedron. The distribution of the intensity of diffracted X-rays as a function of reciprocal space coordinates and rocking curves was analyzed using the kinematic theory of X-ray scattering in real crystals. The experimental and theoretically predicted values of the helical dislocation densities in the CdTe:Cl and MoO x /CdTe:Cl crystals with perfect and mosaic structures were compared. Two-fold increase in the dislocation concentration in the MoO x /CdTe:Cl heterostructures as a result of compression deformations of the CdTe:Cl crystal lattice was found. The ~0.1 μm thick transition deformed layer at the boundary between the MoO x film and CdTe:Cl single crystal significantly affects the electrical and spectroscopic properties of the obtained systems as the materials for γ-radiation detection.

Published: December 2023

Introduction. Legal personality is a fundamental category in civil law relations and in civil law in general. However, despite the significant place it occupies in the system of law, this category does not have a legal definition. In the paper, the main features inherent in legal personality as a category of law are identified and analyzed; various approaches to the definition and essence of civil legal personality are studied; the distinctive features of the legal personality of individuals participating in transactions on the Internet are identified; conclusions are drawn regarding the place occupied by this category; and the role and importance in the general system of law, as a whole, and in transactions in electronic form, in particular, are determined. Purpose. To compare different approaches to understanding legal personality, to determine the characteristic features inherent in this category, to find the distinctive features of legal personality when making transactions on the Internet, and to identify the specifics in the digital format of transactions. Methods. In the course of the study, the methods of dialectical and formal logic, comparison, analysis, and synthesis are used. Results. Legal personality is a basic institution of civil law and is a legally independent form in which parties in civil law relations are cast. This category has specific, defining features, for example, when transactions are made remotely. Conclusions. As a result of the conducted legal research, it has been revealed that the legal personality of parties to online transactions has distinctive features that make it possible to find out and distinguish such persons from other subjects of civil law relations. The legal regulation of transactions made in electronic form requires a detailed and in-depth study and the adjustment of legal norms.
On Legal Problems of Waste Management at the Regional Level

Published: December 2023

Introduction. The paper notes that Russia’s transition to a “green” economy will require the greening of all spheres of economic activity, including waste management. Now, a number of measures have been taken at the federal level aimed at improving the efficiency of production and consumption waste management, reducing waste burial and increasing waste disposal volumes, and building new waste processing plants. However, these measures are universal in nature and poorly take into account the specifics of the regions. To account for it at the level of the subjects of the Russian Federation, it is necessary to adopt their own regulations. Purpose. To consider the specifics of the three Caspian regions (the Astrakhan region, the Republic of Dagestan, and the Republic of Kalmykia), to identify their natural and climatic features that can be taken into account when developing draft regulations in the field of waste management, to analyze the provisions of scientific doctrine and the main discussions about the cardinal problems existing in the field of waste management, which can be used during the preparation of these legislative drafts. Methods. The methodological framework for the study was the methods of scientific cognition, among which the main ones were the methods of consistency, analysis, and comparative law. Results. It is necessary to adopt at the regional level a set of measures for the development of waste management infrastructure, the construction of waste processing plants, and the creation of a system of incentives for environmental entrepreneurs engaged in the industry of production and consumption waste management.

Authors:   Institute of State and Law of the Russian Academy of Sciences, Rossinsky Sergey
Published: December 2023

Introduction. The reasonableness of the currently existing investigative procedure for lodging a criminal claim (bringing charges), subject to further consideration and resolution through justice, is one of the most controversial issues related to the criminal procedural regulation of the preliminary investigation. In this regard, the purpose of the paper is to identify the true reasons that predestined the granting investigators of the authority to make a decision on an indictment as a defendant and to draw up the indictment. Methods. The methodological framework for the work consists of general scientific (dialectical, systemic, structural-functional, logical, etc.) and specific scientific (formal-legal, comparative-legal, historical-legal, prognostic, etc.) research methods. The results of the study have made it possible to link the emergence of an investigative procedure for lodging a criminal claim with a negative assessment of the work of the pre-revolutionary prosecutor’s office, including the mechanisms of prosecutorial supervision of the preliminary investigation, by persons responsible for the formation of early Soviet criminal justice. Conclusions. The views and law-making positions expressed more than 100 years ago should contribute to resolving the issue of the expediency of the investigative procedure for bringing charges or the need to transfer such powers to the prosecutor.

Introduction. Crimes related to illicit narcotic drug trafficking have a wide range of negative consequences for society. People who use drugs become addicted to them, get infected with dangerous diseases such as HIV and hepatitis, and risk not living to old age. The consequences for others include the deterioration of the criminal situation, street crime, and various types of violence. There is an increase in the number of narcotic drugs manufactured at home from freely sold medicines. Synthetic drugs and psychoactive substances coming from abroad represent new varieties. For their delivery, the capabilities of the Internet, international mailings, and various methods of concealment are widely used. The paper analyzes the judicial practice of applying criminal liability for drug trafficking by the courts of the Russian Federation. The problems are identified regarding the qualification of the commission of the above crimes through complicity. The purpose of the study is to analyze judicial practice in criminal cases initiated under Articles 228, 228.1 of the Criminal Code of the Russian Federation. Methods. The methodological framework for the study is an inductive generalization. In order to ensure the objectivity of the study, the analyzed problem is revealed through the transition from more specific characteristics to more general ones. Results and conclusions. The author concludes that Resolution of the Plenum of the Supreme Court of the Russian Federation No. 14 of 15.06.2006 has undergone changes; it lacks such qualification as complicity in the acquisition of narcotic drugs without the purpose of sale, which contradicts the provisions of the General Part of the Criminal Code of the Russian Federation regulating the institution of complicity.

Published: December 2023

Introduction. The article examines the problem of the motivation of court decisions in criminal procedures. It has been established that motivation determines the quality of court decisions. The author comes to the conclusion that the basis of motivation is the discretion of the court. The author analyzes the discretion of the court as an aspect of the judge’s activity. The motivation of court decisions is aimed at their quality and accessibility for the population of the country. The author believes that motivation is aimed at increasing the authority of the judiciary. The purpose of the article is to reveal motivation through the concept of court discretion. Research methods: dialectical method of cognition, system analysis, logical-legal method. Results. Based on legal analysis, the motivation of court decisions is considered by the author to be a component of the court’s discretion. The limits of the court’s discretion are determined by the rules of law and the motivation of decisions; therefore, they are called the normative limits of discretion. The limits under consideration allow the court to make a decision based on the circumstances of the case and its motivation. Conclusion. The discretion of the court should be considered as the interaction of procedural rights aimed at making a lawful decision. In other words, the basis of discretion is the position of the court, based on law enforcement practice, motivation of decisions, systematic analysis of the rules of law, and a creative approach within the framework of the criminal case under consideration.

Coffee is Vietnam’s main exported product. It accounts for approximately 90% of the country’s annual exports. In the beginning of the 20th century, Vietnam was the second largest world exporter of coffee after Brazil. However, the quality was low, and the product lost out in price. The economic efficiency of production and processing was not high because of traditional technologies which were used, so the contribution to the country’s economy was considerably lower than it could be with the use of digital innovations. Currently, there are no completed studies of reasons for the low efficiency of Vietnam’s coffee production and processing, and of the analysis of innovative transformations’ dynamics. Therefore, the purpose of the study is to reveal the role and advantages of innovative digital technologies in coffee production and determine their economic efficiency. The results of the study suggest that over the past two decades, the global “coffee” market industry has expanded significantly; the demand for coffee grew by 65%. That is the main driver of development and a source of income for more than 12 million farms (more than 25 million families) in producer countries. The manual coffee production used in Vietnam cannot compete with modern digital technologies of countries that are leaders in the coffee market (Brazil, India, Thailand, etc.). The experience in introduction of technologies with international certification according to product quality standards on the area of 125.785 hectares in 2017, in the provinces Daklak, Lam Dong, Gia Lai and Kon Tum showed an increase in productivity by 10–30%. In the structure of Vietnamese coffee exports, 95% is green coffee, so export income is three times lower than the cost of processed coffee beans. Thus, the application of innovative digital technologies of cultivation and processing is a vital factor in the Vietnamese coffee industry. The result of their introduction will be sustainable development of coffee production, competitiveness growth of Vietnamese coffee products in the world market.

What does the digitization capability of local governments mean? What does it mean for a municipality to actively use digitization tools? How does the digital space affect the quality of life of the population and the attractiveness of businesses? Our goal is to present the digital tools that can be used to improve the quality of life of people living in settlements. Digitization is reflected in the way citizens and industries do business, helping them to access municipal functions and interact with the municipality on a daily basis. In addition, digitalization makes the management and operation of a settlement more sustainable. Last but not least, digitalization can make the everyday lives of those who live in it more livable and enjoyable. Our method is literature review, source analysis, and knowledge of economic and social processes. During our research, we explore the opportunities offered by digitization through examples, which we combine with knowledge management tools. We present models and tools for what needs to be done to improve urban life to the increasing satisfaction of residents. According to our results, municipalities do not use the toolbox of digitalization in the field of online administration, automated process management and marketing tools. Digitalization also provides opportunities for environmental awareness, administration, and support for companies and smart cities.
AMPHIPHILIC BLOCK COPOLYMERS AS STABILIZERS OF SILICA AND SILICON NANOPARTICLES SYNTHESIZED IN PLASMA DISCHARGE UNDER ULTRASONIC CAVITATION
Authors: Butusova O. A. , Bulychev Nikolay A.
Published: December 2023

A range of tailor-made amphiphilic block copolymers of acrylic acid as a hydrophilic block and styrene
as a hydrophobic block, as well as their homo- and random copolymers, were utilized for colloidal stabilization of silica and silicon nanoparticles in their hydrocarbon suspensions. Silicon-containing nanoparticles were synthesized in plasma discharge under intensive ultrasonic cavitation by decomposition of tetraethoxysilane. The influence of the molecular characteristics and architecture of the applied copolymers on the stabilization effect was examined. Random copolymers of styrene and acrylic
acid were shown to provide poor stabilization effects, while diblock and triblock copolymers acted as
effective suspension stabilizers. As a result of this study, the optimal molecular structure for diblock copolymers and the optimal molecular architecture for triblock copolymers were established. These findings allowed us to conduct a short reconnaissance study of the structure-dependent stabilization effects, opening prospective routes for tunable compatibilizers with stability varied as a function of composition.

Published: December 2023

This study investigates the experiences and perceptions of Korean college students regarding the use of ChatGPT as a tool for revising paragraphs in a general English course focused on academic writing skills. A total of 71 student participants completed a survey questionnaire about their perceived benefits and challenges in employing ChatGPT for writing revision and anticipated teacher roles in the process. For data analysis, descriptive statistics and thematic analysis methods were used. The findings reveal a positive reception from the students. They expressed satisfaction with the use of ChatGPT for their paragraph revisions, indicating that its feedback was helpful and trustworthy. The benefits of ChatGPT included the convenience of its instant responses, unrestricted use across time and space, and accurate error correction in areas such as vocabulary, grammar, and paragraph flow. Some challenges were also raised, such as the lack of error descriptions, incomprehensible feedback, misalignment of responses, concerns about diminished authorship, and uncertainty about learning effectiveness. These findings suggest the potential of ChatGPT as a supplementary tool for writing revision, emphasizing the importance of a balanced approach between AI-driven and human feedback. The study also underscores the crucial role of teachers in effectively integrating ChatGPT into writing instruction.
JUDICIAL JURISDICTION OF CORPORATE DISPUTES ARISING IN NON-PROFIT ORGANIZATIONS
Authors:   Perm State University, Liubimova E. V.
Published: December 2023

Abstract: the article discusses the distribution of corporate disputes between courts of general jurisdiction and commercial courts. At the moment, the legislator is guided by the division of legal entities into commercial and nonprofit organizations. The article notes that commercial activity is not included in the subject of proof in corporate disputes, therefore it is a random criterion of judicial jurisdiction. Analyzing the rights and obligations of participants of different companies, the author comes to the conclusion that the division of legal entities into corporate and unitary is important when considering corporate disputes. According to the author, if we recognize the need for a different procedure for the consideration of corporate disputes, it seems more appropriate to allow the separation of cases related to the creation, management and liquidation of unitary legal entities.
