BIOACTIVE SURGICAL SUTURES
Authors: Zhukovsky V.
Published: December 2023

Investigations carried out into the development of bioactive surgical sutures and radioactive fibres are presented. Anti-microbial surgical sutures, which for a long period provide the wound with the antibiotics settled in their structure, can be of considerable use for precautions and treatment of surgical sepsis. Simultaneously the hydrolytic influence of proteolytic enzymes on the necrotising tissues, which serve as a nutrient medium for microbes, is desirable. The anaesthetic and anticancerous properties of sutures are also of such importance. Antibiotics (such as clindamycin, gentamycin, lincomycin etc.), proteolytic enzymes (such as tripsin and pepsin), anaesthetics (such as lidocaine, novocaine, trimecaine, and pyrocaine), and anti-tumour medicaments (such as prospydin, 5- fluorocyl, sarcolysin etc.) were fixed by us separately or in different combinations onto cationexchanging polypropylene fibres with the help of ion-exchanging bonds. A principally new type of biologically active surgical fibres is radioactive fibres which exhibit their action by the emanation of ionising radiation from radioactive isotopes fixed in the fibres' structure. Sulphur-35 isotopes emanating soft beta-rays, and phosphorus-32 isotopes emanating much harder electrons were fixed by us onto polypropylene, polyethylene terephthalate, polyamide, and polyvinyl alcohol fibres by firm covalent bonds. Biological, medical and clinical tests showed the high effectiveness of the biological active sutures developed by us, as well as that of the radioactive surgical fibres used in different forms.
ENVIRONMENTAL INDICATORS OF TEXTILE PRODUCTS FOR ISO (TYPE III) ENVIRONMENTAL PRODUCT DECLARATION
Authors: Nieminen-Kalliala Eija
Published: December 2023

Abstract

The objective of this research project was to develop technical environmental indicators
of textile products for ISO Type III environmental product declaration. The standardisation
of an environmental declaration for products (Type III) currently under way in the ISO
offers an interesting opportunity for communicating the environmental effects of products
in a global and uniform manner. The research was conducted in co-operation between
the Tampere University of Technology, the Federation of Finnish Textile and Clothing
Industries and the more important Finnish textile producers and sellers. This paper
examines the manufacturing processes of the selected textiles by using Life Cycle
Inventory Analyses (LCI) of the Life Cycle Assessment (LCA) method, and also compares
the data available with the criteria for different environmental labels (EU eco-labelling and
the Öko-Tex standard). As a result of this research project, a proposal is presented for
the formulation of technical environmental indicators of different types of textile products,
i.e., of essential environmental effects, to support the development of ISO Type III
environmental declaration criteria.
THE MECHANISM OF END BREAKAGE IN RING SPINNING: A STATISTICAL MODEL TO PREDICT THE END BREAK IN RING SPINNING
Authors: Ghosh Anindya , Ishtiaque Sayied , Rengasamy Seenivasan , Patnaik Asis
Published: December 2023

The mechanism of end breakage in ring spinning is a complex phenomenon, and is entirely different from the yarn failure mechanism during a tensile test. In this paper a possible mechanism of end breakage is reported. A statistical model is developed for predicting the likely end breakage rate in ring spinning. The important factors in governing end breaks are the mean yarn strength, yarn strength variation, mean value of the peak spinning tensions and the variation of yarn mass irregularity. Some practical aspects have also been discussed to tackle the problem of when the breakage rate suddenly increases.
INDIRECT DETERMINATION OF THE LOAD INTENSITY PARAMETERS ACTING ON THREADS DURING KNITTING BY MEANS OF TESTING STRUCTURE CHANGES IN SPECIAL PREPARED YARN
Authors: Charalambus Andreas
Published: December 2023

Intensive loading of yarn processed by knitting influences the efficiency of the process and the quality of the knitted fabrics which are manufactured. It is frequently necessary to determine their value and eliminate the negative effect if such a necessity arises. In this work we propose an indirect method for measuring and testing loads and load changes acting on the yarn during the knitting process. By means of this method it is possible to see which parts of the stitch structure are the most loaded, and thus predict the consequences of these loads on the yarn structure. Special knitted thread-bands are used, which are photographed at the moment of knitting or scanned after the unknitting of the knitted fabric. The structure of these bands easily imprints ‘copies’ of the value and the type of loads.

Published: December 2023

Abstract
Natural silk waste is an important by-product of the silk industry in Uzbekistan. Solutions to the problem of natural silk waste have been used to improve the properties of the locally produced polyacrylonitrile fibre. Nitron, and the effectiveness of this dissolution process, are very important to the textile industry in Uzbekistan. Previous methods used to dissolve natural silk waste have been time-consuming and relatively inefficient. This paper describes a new method for dissolving natural silk waste, using a high-frequency electromagnetic field.
CELLULOSIC FIBER FOR ODOR AND PH CONTROL
Authors: Dutkiewicz Jacek K.
Published: December 2023

Abstract

A new approach to odor and pH control in medical and hygiene care applications relies
on a treatment of absorbent fluff with selected enzyme inhibitors. Cellulose fiber was
found to be a convenient carrier for some chemicals which modify the structure of an
enzyme and/or block its active site. In an absorbent system exposed for example to body
liquids containing urea, selected substances, when released from the fibrous material,
can effectively slow down enzymatic hydrolysis of NH2CONH2 and suppress the emission
of ammonia. An additional benefit of this technology is in this case a control of the pH of
the skin environment and keeping it closer to neutral or slightly acid region. A slowdown
of the ammonia emission can be enhanced by blending sodium polyacrylate-based
superabsorbent polymer (SAP) particles with the modified cellulose fibers. Suitable
inhibitors of urease can also be applied directly to absorbent nonwoven fabrics
comprising fluff.
EFFECT OF DRAWING DIFFERENT MFI POLYPROPYLENE FILAMENTS ON A GRADIENT HEATER
Authors: Mukhopadhyay S. , Deopura B. L. , Alagirusamy R.
Published: December 2023

High-modulus and high-tenacity polypropylene fibres were prepared by drawing as-spun filaments on a heater with a temperature gradient. The results on two different MFI PP show that the fibre properties are significantly affected by the temperature profiles at the final stage of drawing on a gradient heater. High crystal perfection and crystallinity at very high draw ratios have been obtained for the gradient drawn fibres. The gradient drawn filaments showed superior mechanical properties when compared to filaments drawn over a constant temperature heater. Fibres with an initial modulus of 16.4 GPa and tenacity of 875 MPa were obtained in the process. The molecular weight of the parent material significantly influenced the mechanical properties of the material. High molecular-weight (low MFI - Melt Flow Index) materials are characterised by comparatively lower modulus but higher tenacity values. High draw ratios were possible for the higher MFI samples, leading to more orientation and modulus.
MANUFACTURING 3-D BRAIDED COMPOSITE TRUSSES

Published: December 2023

Abstract

A design methodology for the production of complex shapes through near net shape
manufacturing is presented. The data was obtained by using a 3-D circular braiding
machine that was designed and constructed by Prof. Dr. Aly El-Shiekh. Production of a
braided truss shows the procedures required for producing right-angled and contoured
parts, as well as the feasibility of producing such parts. The FRPC (Fibre-Reinforced
Polymer Composites) truss reinforcement system was designed to simulate the
conventional iron truss reinforcement system typically used in a concrete bridge deck. A
technical comparison of FRPC (Fibre-Reinforced Polymer Composites) truss and steel
truss is carried out with respect to weight, cost, compression and bending strength.
Experimental results are presented to show how the nominal stresses (compression and
bending) of 3-D braided composite trusses depend on truss height, truss width and truss
angle, i.e. the number of working layers, number of yarns per each layer, braiding pattern
and number of beats per cycle. It is shown that accurate mathematical models could be
developed from the laboratory data to predict the compression and bending stresses of
the truss from the basic braiding machine settings by using factorial design. The excellent
fit of the predicted values with the measured values confirms that the mathematical
models developed can be used to make accurate prediction of the compression and
bending stresses from a knowledge of the truss specifications.
STUDY OF THE WEAVABILITY OF ELASTANE BASED STRETCH YARNS ON AIR-JET LOOMS
Authors: Meulemeester Simon De , Langenhove Lieva Van , Kiekens Paul
Published: December 2023

Abstract

Elastane yarns are often used to produce stretch fabrics on knitting machines as well as rapier weaving machines.
On air-jet weaving looms their use is still limited. That is why the objective of this paper is to investigate the
weavability of elastane based stretch yarns on air-jet looms. Bobbins of elastane were woven on an air-jet loom
and a distinction of the bobbins in three categories was made according to the most important production
processes for elastane yarn: core twist, core spun and air covered. Yarn properties such as linear density,
elongation at break and Air Index value were determined, weaving tests were performed and properties of the
resulting fabric were determined.
MECHANICAL BEHAVIOUR OF SEAMS ON TREATED FABRICS
Authors: Kordoghli Bessem , Cheikhrouhou Morched , Kacem Saidene Chiraz
Published: December 2023

Abstract

The purpose of this work is to find out the performance of seams after successive treatments applied to fabric.
Performance of seams is given by their load/elongation behaviour. In this study, woven fabrics are chosen to
investigate the effect of their chemical and mechanical finishing process (desizing, scouring, bleaching, dyeing
and sueding) on the behaviour of the seams. Three factors have been studied: Treatment, Density (number of
stitches per centimeter) and seam direction (weft or warp direction). Two responses are measured: seam
elongation at break and seam breaking force. The initial fabrics properties before stitched have an important
impact on the behaviour of the seams. This work explains that it is more useful to study the yield point than the
rupture point; because for the wear, the elastic phase (recovery) is more important than the plastic phase.
Studying yield point of seams explains better the reality limit of use of stitched fabrics. The increase of the
number of stitches per centimetre ameliorates the breaking resistance of seam, but not the elongation at break.
However the density has small effects on the yield point.
COMPUTER ANALYSIS DISTRIBUTION OF THE YARN LINEAR DENSITY FROM OPEN END SPINNING MACHINE
Authors: Idzik Marek
Published: December 2023

Basing on a detailed kinematics scheme of the R1 Rieter rotor spinning machine, calculation of spectral characteristics of yarn made on the spinning machine was done. The calculations served to create a computer programme facilitating the qualitative evaluation of the spinning process on the R1 spinning machine. It also allows a rapid localising of mechanical damages and technological errors in the machine. The calculations make it possible to detect the sources of periodical faults and damages of yarn which follow from: the noncentred work of elements of the spinning machine or from their being damaged, from damaged pulleys, gear wheels, driving belts, from dirt or damages of the elements driving the roller etc.
Competing for Jobs: How COVID-19 Changes Search Behaviour in the Labour Market
Authors: Bauer Anja , Keveloh Kristin , Mamertino Mariano , Weber Enzo
Published: December 2023

We provide insights on how job search changed in the Covid-19-crisis by analysing data from the LinkedIn professional network for Germany. We find that competition among workers for jobs strongly increased – which is due to additional job seekers rather than higher search intensity. Furthermore, the LinkedIn data show that people from industries particularly affected by the crisis applied much more frequently and there had been a substantial shift in the target industries for applications. Finally, we find that at the onset of the Covid-19-crises applications were made significantly more often below and significantly less often above a person’s level of seniority.
Public History and Wellbeing: A Comparative Analysis of the Impact of Digital and In-Person Engagement on Visitors’ Subjective Wellbeing at Elizabeth Gaskell’s House, UK
Authors: Luck Amy , Sayer Faye
Published: December 2023

Over the last two decades, there has been an emergence of research pertaining to the impact of in-person engagement with historical sites on visitor wellbeing. Yet, despite this increasingly prolific research into the impact of historic places on individual visitors’ or participants’ wellbeing, the impact of digital online engagement with historical places on user wellbeing has been largely overlooked. This research sought to investigate and compare the impact of digital engagement versus in-person engagement on wellbeing at the heritage site Elizabeth Gaskell’s House (UK). The quantitative and qualitative evaluation is based on public health care accredited measures (PANAS), previously piloted wellbeing measures designed for use in a heritage context (MWS), and visitor/user commentary. These methods enabled this study to begin to determine the differential wellbeing impact when engaging with heritage online or in-person and conclude that digital engagement provides an opportunity for historic places to lessen wellbeing inequality and support wellbeing.
Private Nuisance: The UK Supreme Court Take a View
Authors: Bagshaw Roderick
Published: December 2023

Fearn v Board of Trustees of the Tate Gallery, required the UK Supreme Court to resolve claims that by operating an open-air terrace, from which visitors could enjoy a high-level view of London, the defendants were committing the tort of private nuisance against the owners of nearby luxury flats. The Court decided that the intrusive staring into the flats by visitors to the terrace could be a form of private nuisance, but split as to whether the tort was being committed; a minority thought that it would be necessary to take account of the claimants’ flats being glass-walled, and consequently unusually vulnerable to ocular intrusion, and the possibility of the claimants mitigating their discomfort by using blinds, whilst the majority insisted that it was straightforward to hold the defendants liable. This article concentrates on the majority’s re-statement of the basic test for liability in private nuisance, in particular their shift from an approach that assesses the “reasonableness” (or otherwise) of the defendant’s activity to one that relies heavily on a distinction between “common and ordinary” and “special and unusual” uses of land. It concludes that several key elements in the re-statement will require further elucidation, and that the key distinction does not reflect the values that its proponents hoped that it would.

Wittichenite Cu3BiS3 thin films have received significant interest as light harvesters owing to their suitable optoelectronic properties and presence of earth-abundant, and non-toxic elements. We have synthesized Cu3BiS3 thin films by a two-stage process; in which, Cu/Bi/Cu metallic stacks were thermally evaporated and then sulfurized at 400 o C for 10–60 min in a quartz tubular furnace. The influence of sulfurization time on the structural, microstructural, compositional, optical, and electrical properties of the films was investigated. The results revealed that the films were orthorhombic Cu3BiS3 with the following lattice parameters: a = 0.768 nm; b = 1.043 nm; and c = 0.674 nm. Films uniformity, compactness, and crystal grain size increased upon increasing the sulfurization duration. On increasing the sulfurization time, the elemental stoichiometry of the films improved, and the direct optical bandgap increased from 1.38 to 1.40 eV. Additionally, Cu3BiS3 films exhibited p-type electrical conductivity and the electrical resistivity decreased with the increasing sulfurization time. Consequently, the Cu3BiS3 films synthesized at 30- and 60-min sulfurization durations can be applied to thin-film solar cells.

Shift work and evening chronotype are associated with hepatic fat fraction and non-alcoholic fatty liver disease in 282,303 UK biobank participants
Authors: Maidstone Robert , Rutter Martin K , Marjot Thomas , Ray David W , Baxter Matthew
Published: December 2023

Background and aims

Non-alcoholic fatty liver disease (NAFLD) has rapidly become the most common liver disease worldwide. Modern lifestyles have been linked to this rise in prevalence with changes in rhythmic human behaviour emerging as a possible mechanism. We investigated how shift working patterns and chronotype were associated with hepatic fat fraction and NAFLD in 282,303 UK Biobank participants.

Methods

We stratified participants into day, irregular-shift, and permanent night-shift workers. We then utilised multiple methods of disease identification including (i) Dallas steatosis index (DSI), (ii) ICD10 codes, and (iii) hepatic proton density fat fraction (PDFF) and examined how shift work exposure impacted these variables. We further assessed the relationship of baseline chronotype with liver phenotypes using these same outcome measures.

Results

Compared to day workers, irregular-shift workers were more likely to have a high DSI (OR 1.29 (1.2–1.4)) after adjusting for major covariates with some attenuation after additional adjustment for BMI (OR 1.12 (1.03–1.22)). Likelihood of high DSI was also increased in permanent night-shift workers (OR 1.08 (0.9–1.29)) in the fully adjusted model. Mediator analysis revealed that BMI was a significant mediator of the shift work effect. Compared to participants with intermediate chronotype, those with extreme late chronotype had a higher likelihood of high DSI defined NAFLD (OR 1.45 (1.34–1.56)) and a higher likelihood of NAFLD/NASH by ICD10 code (OR 1.23 (1.09–1.39)). Hepatic PDFF was elevated in irregular shift workers, but not permanent night-shift workers.

Conclusions

Irregular-shift work and extreme late chronotype are associated with pathological liver fat accumulation, suggesting circadian misalignment may have an underlying pathogenic role. These findings have implications for health interventions to mitigate the detrimental effect of shift work.
ANALYSIS OF POSSIBLE APPROACHES TO DETERMINING THE MOST RELIABLE METHOD OF ENERGY BALANCE CONSTRUCTION

In the process of analyzing the methods, numerous results were obtained. On the basis of which it can be concluded that the results of calculations carried out using the method of maximum likelihood became the closest to the actual values. However, it is important to note that these results turned out to be very close to the results obtained when determining the average value of the data set. The main advantage of this definition is ease of implementation. Since the experiments were conducted on the basis of a relatively small amount of initial data, it is impossible to consider that the determination of the average value is the most appropriate for its implementation. The conclusion is suggested that there is a need to conduct an analysis based on a larger amount of initial data. And also, using other methods of finding the most reliable energy balances. The possibility of constructing maximum likelihood graphs when assessing the quality of energy balance indicators and directions of possible use of this method in tasks were considered.

The objective of this study is to establish a methodology for the equitable distribution of loads among participants in an en-ergy community consisting of low-power renewable energy sources. This is achieved through the utilization of a modified resource allocation algorithm. The proposed approach effectively considers multiple criteria, limited initial information, and the need for flexible assignment and reprioritization of objectives and constraints. To achieve this, linguistic characteristics are employed. Furthermore, under specific conditions, the list of objective functions can be expanded to capture the diverse interests of actors in the electricity market, such as suppliers and operators. To validate the effectiveness of the proposed methodology, statistical data on the operation of renewable energy sources supplying electricity to consumers within a spe-cific region was utilized. Optimal operating modes for these sources were investigated. The focal point of this research is to develop a tool that ensures the optimal functioning of the network comprising low-power sources. To attain this, optimization criteria encompassing technical, economic, and environmental aspects were employed to derive the optimal operating modes for the renewable energy community.

On the basis of mathematical modelling of electromagnetic processes, electrical losses in the metal frames of the two-inductor induction channel furnace in a wide range of specific electrical conductivity of the non-magnetic material of the frames were determined. Research was conducted for two options for sectioning the lower frame of the furnace (vertical and horizontal) and two values of the phase angle between the voltages on the inductors (0 and 180 electrical degrees). For these cases, losses in furnace frames made of ferromagnetic material (construction carbon steel and magnetic stainless steel) were also calculated. Recommendations are presented on the selection of the frame material, the sectioning option and the phase angle between the voltages, which ensure minimal electrical losses. Ref. 13, fig. 4.

The results of a comparative study of two speed control systems for a DC motor with permanent magnets are presented: a cascaded system based on PI controllers, and a single-loop system developed on the basis of model predictive control methods. The research was carried out by the simulations for the case of speed trajectory tracking task. It is shown that, under the conditions of known parameters, the controller based on predictive control, designed as a system with one input and one output, unlike the system with PI controllers and compensations of derivatives of the reference signal, does not provide asymptotic speed trajectory tracking. The transients during constant load torque compensation are similar, both control schemes provide asymptotical speed regulation with similar performances. In the case of introduc-ing variations of DC motor moment of inertia, the levels of dynamic trajectory tracking errors become commensurate for both control systems. Unlike the system based on PI regulators, the controller based on model predictive control does not need to measure the armature current and provides improved dynamics in voltage limiting modes.

La minificción hispanoamericana
Authors: Orjuela-Acosta Ana María
Published: December 2023

Minificción es el término que cobija de manera global la diversidad de creaciones literarias breves en la literatura hispanoamericana. Esta forma literaria tiene sus bases más notables en el Modernismo y las Vanguardias, se legitima en el siglo XX y llega a consolidarse a finales del mismo siglo y comienzos de este. La minificción, como apuesta creativa, llega a romper las bases de lo canónico, desafía a la historia misma de la literatura y juega como nunca antes con estrategias intertextuales y de hibridación de formas, formatos y contenidos. Dentro de tales apuestas, la atraviesa la compleja red de relaciones del mundo digital y de la globalización, propias del presente siglo. Por otro lado, Todorov (1988) señala que la aparición de un nuevo género resulta de la transformación de uno o varios géneros preestablecidos. Frente a ello, Fernando Valls (2015) asegura que un género surge cuando el escritor siente que lo que crea no tiene cabida en los formatos ya conocidos. Así, la gestación y la evolución de una nueva forma literaria están atravesadas por una amplia serie de procesos de transformación y transferencia culturales entre creadores, productores y lectores, principalmente.
Contrapalabra negra: la décima afroperuana como género discursivo heterogéneo
Authors: Córdova Ramírez Arturo
Published: December 2023

Una particularidad de la literatura afrodescendiente en el Perú radica en la capacidad de erosionar discursos y géneros canónicos, en contraste con las marcas de representación estereotipadas y monológicas de lo que se ha denominado literatura negrista, provocando así una proliferación de textos heterogéneos marcados por la oralidad, un intenso dialogismo cultural y la incorporación de otras memorias. De esa manera, se establecen espacios de resistencia donde se rearticula la historia negra y sus diversas genealogías, tanto a nivel local como transnacional. En el presente trabajo proponemos un acercamiento a este fenómeno mediante el estudio de la décima, estrofa de origen hispánico de amplia difusión en la cultura popular latinoamericana y que posee un gran arraigo en la tradición oral de los afroperuanos. La décima afroperuana es un ejemplo particular de heterogeneidad e intermedialidad, pues amalgama diversos medios y se inserta en otros como en el cancionero popular o textos narrativos y testimoniales. Mediante el análisis de algunas décimas de Cumanana de Nicomedes Santa Cruz y otras presentes en el testimonio Erasmo, un Yanacón del valle de Chancay, se reconocerá la cualidad de género discursivo heterogéneo que posee la décima en la medida que es depositaria de microhistorias o enuncia una experiencia identitaria diaspórica, donde lo afroperuano se une a una historia transatlántica.
Subgénero del crimen perfecto como problema diferencial
Authors: Estrada Benítez Jorge
Published: December 2023

A pesar de tener rasgos relativamente constantes como una estructura narrativa iterativa, un estilo persuasivo, y motivos como el crimen y la justicia, el subgénero de las narrativas del crimen perfecto es fundamentalmente elusivo porque gira en torno a un problema metaficcional: ¿cómo narrar la perfección? Para responder a esta pregunta, cada actualización del género explora un subtema y echa mano de estrategias narrativas previas. Esto permite postular una genealogía y, al mismo tiempo, significa que el subgénero es propenso a crear variaciones transformativas. El subgénero se expande hacia subtemas y crea una constelación gracias a las similitudes temáticas y estructurales de sus variaciones, pero tiende al mismo tiempo por su fuerza centrípeta hacia la disolución. El género se esconde entonces entre variaciones, se apropia de estrategias de representación narrativa y se va desvaneciendo entre sus variaciones. Esta dinámica dispersiva de circulación invita a discutir el esquema trascendental, que parte de una idea de continuación para entender los géneros literarios y el campo de la representación narrativa, y a pensar un subgénero como sitio metaestable. Para dar cuerpo a estas reflexiones teóricas y reconstruir el subgénero, recurriré a textos de O. Wilde, L. Perutz, J. L. Borges, S. Pitol, R. Rey Rosa y R. Bolaño, entre otros.
Different Blowing Techniques for Palaeolithic Aerophones: Animal Calls, Clarinets, and Flutes
Authors: Praxmarer Michael
Published: December 2023

This article examines how individual approaches in experimental music archaeology may produce different results in reconstructing Upper Palaeolithic aerophones. The paper reveals how sound tools have been used by both prehistoric and modern hunters to imitate animal calls or to chase their prey in a specific direction. The best examples of such practices are the phalangeal whistles and a possible scraper, which have been found along with the remains of Neanderthals in Europe. A possible scraper was recently discovered in the Middle Stone Age African Border cave. Early percussion instruments like drums or different kinds of idiophones might have had multiple functions for the nomadic hunters.
From the 1990s to 2009 a number of new finds of possible Palaeolithic aerophones initiated various experimental studies. Unfortunately, many important questions could not be resolved. I intend to revive the discussions on playing techniques on one hand, and to contribute to the arguments for the non-human origin of some finds on the other.
After discussing sound production techniques of simulated animal calls and summarising the possible use of sound-producers as hunting tools, this article briefly presents two possible reconstructions with reeds and two different techniques of blowing a flute without any mouthpiece.
Multisystem inflammatory syndrome complicated by pulmonary embolism in a child
Authors:   Dnipro State Medical University, Ukraine, Vakulenko L.I. , Riznyk A.V. ,   Dnipro State Medical University, Ukraine
Published: December 2023

Purpose - to present a clinical case of a particular complication of post-COVID multisystem inflammatory syndrome (MIS) - pulmonary embolism (PE) which developed due to primary hereditary thrombophilia in a child for better understanding of the MIS evolution and prognosis in children (MIS-C). Case report. In an 11-year-old boy who previously had no hemorrhagic manifestations, the first symptoms of the disease occurred in the form of fever and a hemorrhagic rash on the lower extremities. Later, he developed signs of respiratory failure, his condition worsened, and bilateral community-acquired viral pneumonia caused by COVID-19 was diagnosed. The child presented with post-COVID MIS manifested as PE, which caused further genetic examinations for hereditary thrombophilia. Primary thrombophilia was detected (F2 gene - prothrombin (20210 G>A) D68.5). Concomitant hereditary pathology was probably the reason for a severe course of the infection and the development of a complication in the form of PE requiring intensive and long-term anticoagulant therapy. Conclusions. In case of PE detection, especially in young patients, examinations to confirm or rule out hereditary or acquired thrombophilia are required, that defines recurrent venous thromboembolism prevention programs. This clinical case report is a contribution to the study on the issues of MIS-C, defining links between pulmonary complications (transient or persistent) and serious sequelae in the future. The research was carried out in accordance with the principles of the Helsinki Declaration. The informed consent of the patient was obtained for conducting the studies.

House Crows Corvus splendens are originally from southern Asia and are considered one of the most invasive birds in the world (Meininger et al. 1980, Nyári et al. 2006, Ryall 2010). They are invading parts of South Africa, mostly along the coastal areas in three provinces (Western Cape, Eastern Cape, and KwaZulu-Natal) (SABAP2). Here we discuss the distribution of House Crows within the eThekwini Municipality, Durban, KwaZulu-Natal from 2019–2023 records collected by the eThekwini Municipality and South African National Biodiversity Institute (SANBI) officials. The record includes the one known roosting site within the Durban Central and most preferred areas within the city.

Authors:   Volgograd Academy of the Ministry of Internal Affairs of the Russian Federation, Grachev Nikolay
Published: December 2023

Introduction. The study of the state and law of the USSR, whose successor and legal continuer is the modern Russian Federation, is impossible in isolation from the activities and political outlook of I.V. Stalin, one of its founders and state leader for almost thirty years. The subject of the paper is the discourse analysis of the political and legal ideology of I.V. Stalin by studying the ontological and epistemological prerequisites of its content and identifying on this basis the historical and cultural conditionality of its conceptual idea. Methods. The methodological framework for the work is a set of methods of scientific cognition, among which the main ones are a combination of dialectics and metaphysics, formational and civilizational approaches, and a number of general scientific and specific scientific methods. The main content of the paper is to establish the features of Stalin’s worldview as a politician and theorist and to study the main points of view on the general nature of his political ideology to provide its most adequate scientific description and definition. Results and conclusions. In relation to the general discourse of I.V. Stalin’s political ideology, the most adequate definitions would be “national Bolshevism” for the period of its formation and crystallization and “national-state socialism” for a later period, which characterizes its content in its mature and final version much more accurately. The fundamental conceptual formula of the Russian nationalization of the communist doctrine was the Stalinist idea of the possibility of building socialism in one single country. It became the value foundation of Stalin’s socio-political project, in whose theoretical justification there was a creative synthesis of the teachings of Marxism-Leninism with the traditions of Russian statehood.

Introduction. The paper defines the immediacy of the problem of identifying the essence of the category “public interest” in the regulation of private law relations. The correlation of private and public interests in Russian law is established. The materials of the legal doctrine and the positions of the higher courts on this concept are analyzed. The signs of public interest in private law are determined. In legal doctrine, the category of “public interest” is very actively used by research scientists. However, there is no explanation of this term at the legislative level, which clearly does not contribute to its uniform understanding in judicial practice and law enforcement activities in general. Due to the high importance of public interests in any state and the absence of a legal definition in Russian legislation, it seems relevant to identify the essence of the category of “public interest” and its main characteristics. The purpose of the study is to identify current trends in judicial practice and analyze the development of legislation on the application of public interest in private law relations. Methods. The general scientific and special methods of cognition were used in the preparation of the paper. The dialectical-materialistic method predetermined the study of the concept of public interest in relation to the private legal sphere. The system method, methods of analysis and synthesis, the formal legal method, and the method of interpretation of the norms of law were also used. Results. The study has analyzed the acts of the Supreme Court of the Russian Federation and the lower courts (the ruling of the Supreme Court of the Russian Federation of 21.09.2022 in case No. 306-ES22-6854; the decision of the Arbitration Court of Appeal of Saratov in case No. A12-32901/2021 of 28.03.2022; the decision of the Arbitration Court of the Astrakhan region of 08.12.2022 in case No. A06-7754/2021). It is proved that the analysis of these acts allows us to conclude about the negative consequences of the introduction of public interest in the sphere of regulating private law relations. Conclusions. The authors have substantiated the need to consolidate the definition of the concept of “public interest” at the legislative level and propose the authors’ vision of this concept. It is argued that when considering cases between individuals or legal entities, the court’s reference to the public interest is not permissible.

Introduction. The emergence of new technologies poses to the Russian legislator a number of complex issues that require rapid and high-quality study, since successful or, conversely, unsuccessful legal regulation of certain processes can promote or hinder their development. These are currently digital technologies and, as their separate element, the metaverse, which exists through the operation of a system of distributed registries, smart contracts, and primary accounting units – tokens. In this regard, the purpose of this publication is to consider the current state and certain aspects of improving the legal regulation of the metaverse and the turnover of a particular type of token, namely the non-fungible token (NFT). Methods. The research is based on the application of logical and dialectical techniques and methods of scientific cognition, comparative legal and legal-technical analysis of texts of normative acts, and materials of law enforcement practice. As a result of the research, the features of the functioning of metaverses as a symbiosis of the real, virtual, and imaginary worlds were considered. The introduction of such technologies into civil circulation, including the sphere of maritime transportation, can significantly improve the quality of legal protection of the rights and interests of subjects involved in these relations. The results of the review became the basis for the following conclusion: the Russian Federation is at the initial stage of the formation of metaverses on its territory, including the issue of legal regulation of such phenomena. In this connection, and taking into account the geopolitical situation, it was proposed by the state forces, with the involvement of the largest Russian transport organizations, on the basis of a public-private partnership, to accelerate the creation of such systems, including regulations in this area, both within Russia and at the regional and international level within the framework of the EAEU and BRICS.

Introduction. The problem of ensuring the rights and legitimate interests of minors involved in the commission of a crime is a priority area of state protection due to the fact that this category of citizens is deprived of the opportunity to fully protect their rights and freedoms because of their moral and psychological immaturity and is in need of an increased level of guarantees from the state. The legal regulation of the protection of the rights of minors, taking into account the provisions of the Constitution of the Russian Federation and international legal norms, is primarily aimed at ensuring their safety from adverse effects on their psyche, especially through criminal encroachments. These principles of state protection continue to apply in the case of a minor’s committing a crime under the influence of elders. The purpose of the study is to eliminate the existing issues and ambiguities that arise during criminal proceedings on crimes with the involvement of a minor and to formulate proposals for improving the legislative framework and law enforcement practice in the direction of ensuring the implementation of the procedural rights of minor participants. In the course of the study, such methods of cognition as formal legal in the form of a study of the norms of law, specifically sociological and comparative legal ones were applied. Results. The paper proposes measures to improve the legislative regulation of criminal proceedings involving minors dragged into criminal activity under the influence of elders. Conclusions. The suggestions and recommendations set out in the paper are aimed at developing uniform investigative and judicial practice and can be used in teaching the disciplines of criminal procedure sciences as well as in the practical activities of officers of preliminary investigation bodies, prosecutor’s offices, and courts.
