Konstrukty cywilizacji i metafizyka transfiguracji w twórczości Romany Kaszczyc
Authors: Chojnacka Wiktoria
Published: December 2023

W twórczości Romany Kaszczyc – artystki przyrody, pogranicza, peryferii, ziemi zachodniopomorskiej i lubuskiej, Puszczy Barlineckiej – w perspektywie sąsiedztwa, współzależności i różnorodności, status granicy traci swoje ontologiczne znaczenie. Puszcza trwa, niezależnie od umownych granic wyznaczonych na administracyjnej mapie Polski. Jednocześnie warto zadać pytanie, czy kultura staje się – powiększającą zachłannie swoje terytorium – sąsiadką natury, a może jej ciemiężycielką? Barlinecka Roma kreuje w swojej twórczości świat, w którym schematy i role społeczne stają się więzieniem. Natomiast w oczach artystki współistniejąca binarność nocy i dnia, mroku i jasności, życia i śmierci jest metafizyczna. Czy zatem granica byłaby transcendentna, epistemologicznie wydarzająca się oraz niezależna od człowieka? Chciałabym przede wszystkim nie tylko przedstawić zasługującą na upamiętnienie artystkę, która świadomie wybrała życie na terenach pogranicza, ale i przyjrzeć się granicy samej w sobie, w jaki sposób wytwarzają się i konstytuują antagonizmy między kulturą i naturą, centrum i peryferiami, światowym uznaniem i regionalnością.
Głównym moim celem badawczym jest natomiast stworzenie interpretacji wybranych tekstów kultury Romany Kaszczyc w świetle rozważań semantycznego doświadczenia pogranicza. Krytyczne opracowanie dzieł literackich i plastycznych przedstawię w perspektywie neoregionalnej oraz ekokrytycznej. Interpretacje staną się jednocześnie pre-tekstem do rozważań związanych z problematyką sąsiedztwa, granicy oraz ekocydu. Inspiracje badawcze czerpać będę z dorobku naukowego m.in. Julii Fiedorczuk, Aleksandry Ubertowskiej, Tatiany Czerskiej, Elżbiety Rybickiej.

Ciało i piękno
Authors: Bieńko Mariola
Published: December 2023

Rozdział jest próbą refleksji na temat inwazyjnych upiększających praktyk cielesnych we współczesnej kulturze konsumpcyjnej. Problematyka podjęta w rozdziale odnosi się do kilku obszarów zagadnień. Pierwszy z nich dotyczy atrakcyjności fizycznej jako indywidualnego i społeczno-kulturowego projektu w przestrzeni prywatnej i publicznej. Kontrola cielesnego wizerunku jednostki łączy się z symboliczną reprezentacją jej tożsamości, która zaczyna być coraz częściej kwestią wyboru. Zarządzanie cielesnością wiąże się z tendencją do autokreacji i “stwarzania siebie”, a także z przewartościowaniem piękna jako wartości społecznej. Drugi obszar zagadnień koncentruje się na zabiegach chirurgii estetycznej, które interpretowane są w kulturze masowej jako konieczność ze względu na przymus posiadania pięknego ciała i zjawisko „hańby” starości. Kultura operacji plastycznych ("nip and tuck") jest konsekwencją konsumenckiej logiki późnego kapitalizmu i neoliberalnej koncepcji życia społecznego. Przedstawione w rozdziale koncepcje teoretyczne, jak i wyniki badań pokazują, w jakim stopniu realizacja projektu „ulepszonego”, „pięknego” człowieka o określonych parametrach fizycznych jest wyrazem kontroli, opresji, a w jakim zaś indywidualizmu i emancypacji jednostki. W tekście wyjaśnione są różnice między kosmetologią, medycyną estetyczną, chirurgią estetyczną, plastyczną i rekonstrukcyjną, opisane są kategorie dysmorfofobii, pracy estetycznej, kosmetycznego spojrzenia, a także zjawiska body shaming, body policy, body neutrality/body positivity etc.

Autorki rozdziału podejmują problematykę ciała i cielesności z perspektywy genderowej. W prezentowanym tekście przyjmują założenie, że ciało jest postrzegane i społecznie funkcjonuje jako ciało upłciowione, wypełnione kulturowymi treściami płci. Referując różne koncepcje wykorzystywane w ramach socjologii płci, pokazują na czym polega i w czym przejawia się upłciowienie ciała, co to oznacza dla jednostki i jakie ma społeczne znaczenie. W pierwszej części rozdziału dokonują wprowadzenia do problematyki ciała i płci w ujęciu genderowym, następnie omawiają przemiany płci kulturowej. W dalszej kolejności podejmują problem znaczenia upłciowionego ciała dla płciowej tożsamości jednostki, pełnionych przez nią społecznych ról i płciowego podziału pracy oraz relacji i nierówności płci. Zwracają również uwagę na kwestię intersekcjonalności w cielesności, a także ciała jako kapitału estetycznego jednostek. W poszczególnych podrozdziałach zdefiniują najważniejsze pojęcia dotyczące ciała i cielesności z perspektywy socjologii płci. Rozdział wieńczą pytania sprawdzające oraz wykaz publikacji, których lektura pozwoli osobom czytającym pogłębić wiedzę na omawiany w rozdziale temat.

Authors: Caballero Montes José Luis , Ríos Ventura Flor Gabriela , Alavéz Ramírez Rafael
Published: December 2023

La investigación tiene como objetivo proponer el mejoramiento de una vivienda construida con fondos de remesas por migrantes de Oaxaca en México, para incrementar sus condiciones de habitabilidad mediante estrategias bioclimáticas pasivas. Para lo anterior, se llevó a cabo una fase diagnóstica del sitio en la agencia Guadalupe Victoria en la región mixteca de Oaxaca, particularizando la caracterización de casas que construyen las personas que emigran a los Estados Unidos. Lo anterior, para seleccionar el caso de estudio de una vivienda de remesas sobre la cual se realizó un análisis termofísico de los sistemas constructivos con las que fue edificada, el cual se complementó con una simulación térmica con el software Ener-Habitat. Posteriormente se llevó a cabo un estudio higrotérmico de la vivienda referida colocando registradores de temperatura tipo HOBOS data logger RH2 en su interior durante el periodo de calor de la zona (mayo y junio 2021). Como resultado se obtuvo que la vivienda de remesas en estudio está descontextualizada al clima de la zona, y requiere adecuaciones en su envolvente para mejorar el confort en su interior. Para mejorar las condiciones de habitabilidad de esta vivienda se propusieron: paneles de “totomoxtle” (hoja del maíz) en muros y cubiertas con aplanado de yeso. Con esta estrategia pasiva se obtienen valores de 63% de amortiguamiento de onda térmica y un desfase de 8 horas en el sistema muro, en tanto que para el sistema techo se alcanzan valores de 100% y 11.5 horas respectivamente. Así mismo se propone la adecuación de un invernadero orientado al Sur-Este, la conducción de calor de estufa Patsari en cocina y comedor e incrementar aleros de 80 cm en techos, garantizando con ello que se mejoren las condiciones de habitabilidad de la vivienda estudiada beneficiando a la familia Gonzáles García propietaria de la casa.

This research is entitled "Community's Understanding About Taking anInch of Land in Pagar Agung Village, Pseksu District, Lahat Regency withthe Hadith Paradigm" The hadith of taking an inch of land is a hadith thatexplains the law for someone who commits unjust acts (land problems), such asthe hadith narrated by Shahih Bukhari, Rasulullah SAW said "whoever abuses apiece of land on this earth then later he will be burdened with land from sevenearths". But this hadith contradicts life in the community in Pagar Agung Village,Pseksu District, Lahat Regency. The problem is how the understanding of themuhadditsin scholars regarding the hadith of taking an inch of land and how theunderstanding of the people of Pagar Agung Village, Pseksu District, LahatRegency regarding the law of taking an inch of land is in accordance with thehadith of the Rasulullah Saw.This type of research uses field research, namely research that goes directlyto the location to make observations about a phenomenon that occurs in order toget answers to a problem.

Developing and Testing Tools for Measuring the Emotional Dimension of Volunteering
Authors: Martynenko Anna
Published: December 2023

Volunteering is an essential part of society. It is considered to be a complex phenomenon which is potentially associated with emotional dilemmas. Emotions of volunteers are crucial for their activity. However, their scientific investigation is lacking, especially when it comes to the methodological aspect. This article presents the results of the methodological development of quantitative indicators of the emotional dimension of volunteering. Using the example of an online survey of 274 social, environmental, event, sports, animal welfare and public safety volunteers, the obtained indicators are tested by searching for a connection with the factors of volunteers’ emotions. As part of our methodology, we have developed new emotional indicators of volunteer activity. Based on the results of the study, we proposed such indicators as valence index, emotional burnout, emotional nature and emotional intelligence. The valence index considers two types (two valences) of volunteers’ emotions — positive and negative. Emotional burnout is expressed as a factor analysis model — the causes of burnout. Emotional intelligence is presented as a summary indicator of emotional processes — for instance, exchange, control, etc. The nature of emotions is represented by interval semantic differentials when building a cluster analysis model. By testing the obtained methods, it turns out that formal and informal volunteers have equally high emotional intelligence and are equally susceptible to burnout. The lowest values of the valence index are found among event volunteers, the highest — among public safety volunteers. With age, the chances of burning out decrease with the presence of constant joy and fun, increase due to excessive pity, and decrease due to compassion fatigue. Compared to men, women are more prone to experiencing emotions: both positive and negative, that is, they have a higher valence index and emotional intelligence.
Integrity, Structurality and Functionality of Everyday Practices of Scientific Mentoring as a Subject of Micro-sociological Analysis
Authors: Ambarova Polina
Published: December 2023

Scientific mentoring at universities can be viewed not only as a scientific and educational institution, but also as a sphere and method of face-to-face interaction, in the process of which the meanings and motivation of the mentor’s and mentee’s research activities are born. Such an approach towards studying scientific mentoring is justified by sociological concepts of everyday life, but their key provisions require adaptation to the problems of scientific mentoring. The idea of science as the everyday life world of university researchers is revealed through a micro-sociological perspective. The interaction of a scientific mentor and a mentee student is interpreted as an element of their life world and is examined through this interaction manifesting in everyday academic activities. The purpose of the article is to examine the integrity, structure (routine actions, the objective world, language, space and time, rituals, signs and symbols, informal traditions) and functionality of everyday practices of scientific mentoring through the prism of sociological concepts of everyday life. A thesis is substantiated that everyday practices of interaction between a scientific mentor and mentee are a way of building and intergenerational translation of the meaning of research work and choice of academic profession.
The Phenomenon of Soviet Factory Sociology (Based on Biysk City)
Authors: Orlov Sergey , Chernyshkov Dmitry
Published: December 2023

This article is devoted to such a scientific and social phenomenon of the Soviet era as factory sociology. The history of the formation and decay of this extremely interesting applied discipline is traced using the example of Biysk city, one of the leading centers of the Soviet defense industry in the 1960’s – 1980’s. The article is based on the personal memories of Sergey Orlov and Lyudmila Mrachkovskaya, who in the 1970’s and 1980’s worked as factory sociologists at such large enterprises as the Research and Production Association “Altai”, the Biysk Chemical Combine, and the Biysk Oleum Plant. Publications of the corporate newspaper of the Biysk Oleum Plant “Za progress” (“For Progress”) have been introduced into scientific circulation as a new source of information about the work of factory sociologists, and this helps in understanding problems that were of concern for the management of Soviet enterprises. In conclusion, several hypotheses are put forward to indicate the horizon for further research on the topic of factory sociology.
Bez obrazu, czyli seriale audio. Problematyka kreacji świata przedstawionego i jego recepcji
Authors: Ogonowska Agnieszka
Published: December 2023

The aim of the article is to show the issues related to the world-building present in audio series in relation to various types of acoustic spaces, a bank of sounds specific to real spaces and the creation of shared fields of action and relations within a given universe in the mind of the recipient. Further attention is paid to the issue of differentiating individual characters by creating distinctive language and sound profiles that mark them out as individuals, as well as assigning them specific sound attributes related to verbal and non-verbal communication and the soundscape characteristic of a specific place of action or social environment. The analysis also takes into account the role of diegetic and non-diegetic sounds in creating the imaginary world and controlling the recipient’s expectations, as well as the processes of understanding and interpreting (or analyzing) the audio series. The article also draws attention to the role of silence, (un)silence and various types of pauses as meaningful aspects of communication and interactions between the characters of the audio series. A separate section is devoted to the characteristics of the elements of the imaginary audio space in the context of individual cognitive universals. The conceptual framework for the analysis of these issues will be intermediality treated as (a) a process of adaptation, but also, in “adjectival” form, as (b) a specific attribute of an audio-series, i.e. an intermedia message and as (c) a user competency attribute. The article is not normative, but descriptive, i.e. it describes creative and reception practices related to the eponymous phenomenon. Due to the breadth of the research field, two perspectives are used in the article: the medium-oriented approach and the user-oriented approach.
Chiny w Hollywood. Wpływ wzrostu chińskiego rynku kinowego na treść współczesnych filmów hollywoodzkich
Authors: Młyński Aleksander
Published: December 2023

In this article I analyse the ways in which contemporary American movies are altered due to the growing influence of the emerging entertainment media market in China. For the first time in history, 2020 saw Chinese box office overtake its American counterpart in terms of yearly income. This milestone illustrates how significant the Chinese market has become. The At the same time, being an authoritarian regime, the PRC has a robust, refined and strict system of censorship at its disposal. In order for a foreign film to be admitted into the Chinese cinemas, it has to pass domestic censorship. In some decades, particularly in the 1970s, American movies were able to promote values which were not adhering to the mainstream, or were even a platform for criticism of the domestic establishment. Currently, the US film industry is predominantly driven by capitalist logic — box office appears to be the main factor dictating the content (and outlook) of fiction films. This model is exploited by China through imposition of numerous restrictions and regulations. In my analysis I show how “forbidden” topics, plots or even small details become altered in order to satisfy the regulations introduced by the Chinese government.
Recepcja serialu „Squid Game” i jego potencjalny wpływ na wizerunek Korei Południowej w Polsce
Authors: Świerczyńska Marta
Published: December 2023

The article presents the results of a study on the reception of the South Korean Netflix production, Squid Game, in the first months after its release. The study analyzes the discourse observable in the articles concerning the series in popular Polish internet portals and focuses on examining the ways of writing about South Korea, the sentiments towards the country, and the premises concerning its image. The study shows mostly positive attitudes towards Squid Game, which could factor into a positive image of the country. At the same time, it shows that the phenomenon of hallyu in Poland remains insignificant or unnoticed in this case despite the observed popularity of the show, and the image of the country resulting from the plot of the series is lost at the stage of media reception.
Między techniką a strategią. Postmodernistyczna dezorientacja widza w „lynchowskim” „Riverdale”
Authors: Krakowiak Anna
Published: December 2023

This article focuses on the streaming series Riverdale (Roberto Aguirre-Sacasa, 2017–2023) distributed by Netflix. The creators of the series overtly refer to postmodern cinema, especially the works of David Lynch. In doing so, they use various kinds of disorientation techniques, that is, narrative devices that complicate the interpretation of what is presented. The author of the article performed a textual analysis on the 6 available seasons, focusing on demonstrating the correlation between the series and postmodern cinema. Then the various aspects of the series were assigned to the possible techniques of disorientation proposed by Andrzej Zalewski. The purpose of this text is to identify the “Lynchianism” in Riverdale and to demonstrate what techniques of disorientation are used by the creators of this series. A further intention is to resolve whether this is in fact a technique (seen by many as a deriving from ineptitude) or a strategy (resulting from deliberate action). The article attempts to view the contemporary work from a postmodern perspective.
A kétoldali aszimmetria fejlődésének vizsgálata történeti embertani anyagon
Authors: Fogl Ágnes
Published: December 2023

In my dissertation I examined the development of the bilateral asymmetry of the upper and lower limb long bones in nonadult skeletal remains from the Bátmonostor-Pusztafalu site which has been dated to the 14-16th century AD. Examining the averages of the long bone measurements of the upper extremity, the growth of the nonadult skeletons from this site was approximately the same as the sample chosen as a standard, thus they proved to be suitable for the purpose of investigating bilateral asymmetry. In the case of the upper limb, bilateral asymmetry was not present at birth. In older age groups, however, it developed gradually. Based on the time of appearance of bilateral asymmetry, the development of its direction and the change in its magnitude with age I drew conclusions about the lifestyle of the examined children and their relationship with their environment. They probably already participated in farming and handicraft work at the age of 7-8, and the physical activities performed during this influenced the long bones of their upper limbs through the loading of the dominant arm, which was manifested in directional asymmetry shifting to the right. The directional asymmetry of the femur showed a shift to the right side with age, and then to the left side in older age groups; thus crossed symmetry pattern could be observed. In the case of the tibia, I obtained partially opposite results to the femur. Shifting to the right in asymmetry was more common, but as age progressed, the differences between the right and left sides levelled off, just like in the case of the femur. As bipedal walking exerts an equal mechanical effect on the lower limb on both sides, asymmetry is less pronounced in the period of postnatal life from birth to adolescence. The bioarchaeological study of limb bone bilateral asymmetry of nonadult skeletons gave me the opportunity to contribute to the biological reconstruction of the findings from the Bátmonostor-Pusztafalu cemetery.

Published: December 2023

This study explores the third language imitation of the Spanish rhotic-lateral contrast by Akan-English bilingual children and adults. Specifically, it examines this phenomenon, with respect to (i) first language transfer in the imitation of the Spanish rhotic-lateral contrast, (ii) the effect of orthographic input on the imitation of the rhotic-lateral contrast in Spanish as a third language, and (iii) the effect of age of acquisition with the inclusion of a comparison between children and adults. Whereas rhotics and laterals are contrastive in most varieties of Spanish and English, they are in free variation in Akan (Guerini, 2018). The participants in this study consisted of 20 Akan-English bilinguals between the ages of 8-10yrs and 18-55. The conditions included an imitation task with auditory input only and another with orthographic input. The results showed evidence of L1 transfer, a positive effect of orthography, and a better performance of children. This study has important implications as it provides data from an understudied population in the field of L2/L3 speech learning.

Published: December 2023

El objetivo de este estudio fue revisar cuáles son los exámenes de imagen más requeridos, sus características y si la elección principal es suficiente para el manejo de la lesión. Se realizaron búsquedas en las bases de datos PubMed, Web of Science y Scopus. Los artículos incluidos eran informes de casos o series de casos de quistes óseos aneurismáticos en la mandíbula o el maxilar que tenían toda la información sobre el caso, desde el diagnóstico hasta el seguimiento. Los 32 artículos incluidos mostraron que el primer examen de imagen requerido es el examen radiográfico panorámico de los casos, y solo unos pocos eligen la tomografía computarizada como primera opción. El tratamiento elegido suele ser el curetaje, y 9 casos presentaron recidivas, aunque 17 no informaron del seguimiento. Los exámenes de imagen 2D fueron el tipo más requerido a la hora de diagnosticar un quiste óseo aneurismático, pero los exámenes 3D fueron necesarios en muchos casos para una mejor evaluación y para proporcionar más detalles.

A. lumbricoides infection is one from 17 neglected tropical diseases in Indonesia. But, Infection of A. lumbricoides in Indonesia often undiagnosed. This is because stool examination with Kato-Katz’s method still rarely done. So it needs something alternative examination that more practical and can be routinely carried out. This study was a diagnostic test for blood eosinofil levels in diagnosing A. lumbricoides infection. This research was conducted at a hospital in Medan. This study involved 63 children who had their parents approval. Children stool were examined by Kato-Katz method as a gold standard and blood eosinofil levels was examined as an index in this study. The results showed sensitivity level of eosinofil is 25% and specificity 96,08%, positive predictive value 60%, negative predictive value 84%, positive likelihood ratio 6,38% and negative likelihood ratio 0,78%. The conclusion is elevated blood eosinofil levels cannot be used as an alternative test Kato-Katz in diagnosing Infection of A. lumbricoides.
Environmental footprint impacts of green energies, green energy finance and green governance in G7 countries
Authors: Tariq Gulzara , Sun Huaping , Ali Sajjad
Published: December 2023

The demand for resources and energy increases as the global population grows, leading to increased ecological and carbon footprints. This study aims to contribute to the global sustainability agenda by assessing the impact of green energy projects, green energy finance, and green governance on reducing ecological and carbon footprints in G7 countries from 1990 to 2020. The findings reveal that there is a noteworthy negative association between ecological footprint, green governance, geothermal energy consumption, hydro-power consumption, and green energy finance. However, a significant positive correlation exists between ecological footprint and biofuels. Additionally, the outcomes lend support to the Environmental Kuznets Curve (EKC) theory in G7 nations. Carbon footprints are evaluated in this study as an alternate measure, and the results are similarly robust. These insights hold the potential to guide policy decisions and investment strategies, and promote the shift to a low-carbon economy by highlighting the connections between the adoption of green energies, green energy finance, green governance, and carbon and ecological footprint reduction, thus paving the way for a more equitable and sustainable future for all.
Algorithmical determination of the equilibrium/stead position of a dynamic system by the finite-step method
Authors: Plaksiy Yuriy
Published: December 2023

The problem of algorithmic estimation of the equilibrium/stationary  state of the dynamic system based on the minimum number of measurements of  the output quantity at equidistant time points is considered. For this, a finite-step method was used, which consists in the formation, according to certain rules, of the sums and differences of the values of the output quantity, which are located symmetrically on the time axis relative to a certain moment that can  be determined a priori. As a result, overdetermined systems of  linear equations are formed with respect to the introduced fictitious unknowns, and based  on the necessary condition for the existence of a solution to these systems, formulas are found to determine the equilibrium/stationary  position  of  the dynamic system. Algorithms for determining the equilibrium /stationary  state for the following mathematical models of the output value are given: in the form of a constant component and a damped  exponent, in the form of a constant component and a damped sinusoid, in the form of a constant component and two undamped sinusoids, in the form of a constant component and a damped sinusoid. It is shown that in the absence of  measurement errors of the output value, the error in estimating the equilibrium/stationary  state of  the transient process depends only on the error in solving the system of  linear equations. Ways of using the redundant number of measurements are discussed.

Keywords: equilibrium position, stationary state, dynamic system, mathematical model, finite-step method, numerical algorithm.
Orientation Quaternion Norm Correction in SINS Algorithms: Calculation Normalization Schemes and Their Efficiency
Authors: Plaksiy Yuriy
Published: December 2023

The problem of correcting the norm of the computed orientation quaternion in the algorithms for the operation of strapdown inertial navigation systems is considered. Two existing approaches to the correction process are considered, the first approach is to normalize the rotation quaternion at the computation cycle, the second approach is to normalize the resulting quaternion. 5 well-known calculation schemes for norm correction are given. To simulate the test motion, we used an analytical quaternion kinematic rotation model based on a sequence of three rotations corresponding to the Krylov angles. The case of linear dependence of elementary rotation angles on time is considered. The model provides analytical representation of the projections of the angular velocity vector of the rigid body on the associated axes and the corresponding quasi-coordinates on the calculation cycle. The results of numerical simulation of the reference motion for a given set of frequencies are presented as dependences of the projections of the angular velocity vector of the rigid body on time and the constructed trajectories in the configuration space of the orientation parameters.

To determine the rotation quaternion on a cycle, the Miller algorithm was used, which makes it possible to obtain an increase in the orientation vector based on ideal information from the angular velocity sensors in the form of quasi-coordinates. The transformation into a rotation quaternion occurs with the help of the corresponding expansions of the trigonometric functions of the true rotation angle (modulus of the orientation vector) in a series.

Based on a numerical experiment, it is shown that the best result of correcting the norm of the calculated quaternion in the sense of the minimum error of the norm is given by one of the finite normalization schemes, for which there is no division operation and ensures the stability of the norm correction in time. The results of numerical simulation of the model rotational motion of a rigid body and the development of schemes for correcting the norm of the calculated orientation quaternion are presented.

Keywords: orientation quaternion, Miller's orientation algorithm, SINS, norm error, computational drift, analytical reference model, quasi-coordinates, numerical simulation.

Authors: Breslavsky Dmytro , Palamarchuk Pavlo
Published: December 2023

The paper is devoted to the description of the problem statement, the modeling approach, and the obtained results on the creep of a thick tube when it is in contact with rods of semi-cylindrical cross-section, which are located symmetrically to its center. An overview of research papers made in the direction of creep contact modeling, including the FEM use, is presented. The formulation of the problem is presented taking into account finite strains and displacements. The contact conditions are described, the variational functional used for the finite element formulation of the problem is presented. Due to the existing symmetry of the geometric parameters and boundary conditions of the problem, it was solved using the plane strain statement. The area of FEM discretization is the fourth part of the tube cross-section, which is in contact with the cross-section of the rod in the form of a half circle. The results of verification studies performed to assess the reliability of solving the creep problem for the cylinder loaded with internal pressure are presented. Different models are discussed for describing the contact interaction, which can be used in the ANSYS software. The advantages of using the Normal Lagrange Method are shown. The tube contact deformation during creep for 10,000 hours was analyzed. The distributions of the components of the stress-strain state obtained by computer modeling along the sections of the contacting elements and the plot of the redistribution of von Mises equivalent stress at the point of contact are presented. The characteristics obtained by calculations of the deformed state of the surface of the cylindrical tube, which arises due to the influence of the contacting rod, are discussed. An approximation was made and analytical expressions of the dependence of the von Mises stress and the length of the contact line on time were presented. The obtained results of solving the creep problem indicate that within approximately 1.25 years due to the contact of the tube with the rods, dent-type defects are formed on its surface.

The object of the study is personal protective equipment such as body armour, and the subject of the work is the study of the processes of destruction of the integrity of personal protective equipment such as body armour in order to find ways to improve their strength characteristics. Protective body armour is a key element of protection for the military, law enforcement agencies and other professions involving risk to life. Modern materials and technologies make it possible to produce bulletproof vests of the highest level of protection, providing not only protection against bullets but also against other hazards such as explosions and shrapnel. However, the systems must have improved ballistic efficiency, be lightweight, flexible and comfortable for effective work. In general, the effectiveness of protective body armour is determined by various factors, including the construction technique of the vest, the type of materials and the finish of the protective panels.

This paper provides a detailed overview of the current state of the art in body armour panel design and various materials for the manufacture of protective plates. A detailed analysis of the different types of protective body armour and their categories is provided. Next, various methods of panel construction, their problems and possible solutions will be presented. Finally, various polymeric fibre and future possible advanced materials, including carbon nanotubes (CNTs), graphene CNTs and super thickened fluids (STFs), will be discussed for the development of enhanced protection panels.

The issue of determining the stress-strain state during creep in models of rotors of steam and gas turbines is considered. The formulation of the problem is based on the general approach of Solid Mechanics using incremental theory to describe creep strains. The Finite Element Method was used as a solution method in the implementation of professional engineering software. The influence of the centrifugal forces on the stress-strain state, which varies during 10,000 hours of creep of the rotor material, is analyzed. Two models of the rotor are considered: a simplified cylindrical and a drum-type rotor, which is described by the geometry of the body of revolution and which consists of several cylindrical parts. Due to the symmetry of the models, the calculation schemes are built on the basis of the use of a two-dimensional finite element of the body of revolution. Algorithms are applied for the preparation of input data can be recommended for use in the design practice of energy industry enterprises. The Norton law was used for creep calculations. The creep of the models in different temperature conditions with the use of various steels used in turbo-building as their material was analyzed. According to the results of the performed computer simulation of the creep of rotor models, the levels of deformation and the nature of the redistribution of stresses that occur under the same load by centrifugal forces in different temperature conditions caused by the operational processes in the turbine have been established. The stress and strain levels in the drum-type rotor were analyzed and the most loaded and deformed areas of it were determined. It is noted that according to the simulation data for the considered model of the drum-type rotor, the level of accumulated strains, is moderate and does not exceed 0.4%, which is suitable from the point of view of the analysis of operational properties.

Analytical-numerical modeling of the process of solid body orientation in quaternions through a sequence of Euler angles for accurate analysis of orientation algorithms in SINS
Authors: Plaksiy Yuriy , Kuznyetsov Yuriy
Published: December 2023

Two concepts for constructing analytical angular test motions of a rigid body for testing orientation algorithms when designing strapdown orientation systems are considered. The first concept is based on representing the orientation quaternion in a sequence of three Euler angles. The second concept is based on a formalized representation of the quaternion as a superposition of trigonometric functions of linear arguments and does not have a clear visual interpretation through the angles of elementary rotations. Analytical expressions for the model angular velocity can be obtained from the inverted kinematic equation in quaternions. The general case of linear Krylov and Euler angles is considered, as well as the case when one of the angles does not change over time. Analytical-numerical modeling of the angular motion of a rigid body and an assessment of the accuracy of the algorithm for determining the quaternion based on fourth- and fifth-order expansions with preliminary application of the Miller algorithm were carried out. For this purpose, the test movement model is supplemented by modeling ideal information from the outputs of angular velocity sensors in the form of quasi-coordinates using analytical formulas for the apparent rotation vector. It is shown that fifth-order formulas provide an improved estimate of the accumulated computational drift compared to fourth-order formulas.
