Emergence of economic and social disparities through competitive gift-giving
Authors: Itao Kenji , Kaneko Kunihiko
Published: September 2024

Several tiers of social organization with varying economic and social disparities have been observed. However, a quantitative characterization of the types and the causal mechanisms for the transitions have hardly been explained. While anthropologists have emphasized that gift exchange, rather than market exchange, prevails in traditional societies and shapes social relations, few mathematical studies have explored its consequences for social organizations. In this study, we present a simple model of competitive gift-giving that describes how gifts bring goods to the recipient and honor to the donor, and simulate social change. Numerical simulations and an analysis of the corresponding mean-field theory demonstrate the transitions between the following four phases with different distribution shapes of wealth and social reputation: the band, without economic or social disparities; the tribe, with economic but without social disparities; the chiefdom, with both; and the kingdom, with economic disparity and weak social disparity except for an outlier, namely, the “monarch”. The emergence of strong disparities is characterized by power law distributions and is attributed to the “rich get richer” process. In contrast, the absence of such a process leads to exponential distributions due to random fluctuations. The phases depend on the parameters characterizing the frequency and scale of gift interactions. Our findings provide quantitative criteria for classifying social organizations based on economic and social disparities, consistent with both anthropological theory and empirical observations. Thus, we propose empirically measurable explanatory variables and characteristic indices for the evolution of social organizations. The constructive model, guided by social scientific theory, can provide the basic mechanistic explanation of social evolution and integrate theories of the social sciences.
The doublecortin-family kinase ZYG-8DCLK1 regulates microtubule dynamics and motor-driven forces to promote the stability of C. elegans acentrosomal spindles
Authors: Czajkowski Emily R. , Zou Yuntong , Divekar Nikita S. , Wignall Sarah M.
Published: September 2024

Although centrosomes help organize spindles in most cell types, oocytes of most species lack these structures. During acentrosomal spindle assembly in C. elegans oocytes, microtubule minus ends are sorted outwards away from the chromosomes where they form poles, but then these outward forces must be balanced to form a stable bipolar structure. Simultaneously, microtubule dynamics must be precisely controlled to maintain spindle length and organization. How forces and dynamics are tuned to create a stable bipolar structure is poorly understood. Here, we have gained insight into this question through studies of ZYG-8, a conserved doublecortin-family kinase; the mammalian homolog of this microtubule-associated protein is upregulated in many cancers and has been implicated in cell division, but the mechanisms by which it functions are poorly understood. We found that ZYG-8 depletion from oocytes resulted in overelongated spindles with pole and midspindle defects. Importantly, experiments with monopolar spindles revealed that ZYG-8 depletion led to excess outward forces within the spindle and suggested a potential role for this protein in regulating the force-generating motor BMK-1/kinesin-5. Further, we found that ZYG-8 is also required for proper microtubule dynamics within the oocyte spindle and that kinase activity is required for its function during both meiosis and mitosis. Altogether, our findings reveal new roles for ZYG-8 in oocytes and provide insights into how acentrosomal spindles are stabilized to promote faithful meiosis.
Water fetching and musculoskeletal health across the life-course in Sub-Saharan Africa: A scoping review
Authors: Meeuwisse Soren , Elliott Susan J. , Bennett Alexa , Kapoor Videsh
Published: September 2024

The world is experiencing a global water crisis and Sub-Saharan Africa (SSA) is expected to be a hotspot for increasing global water scarcity in years to come. Water is quintessentially a gendered issue; indeed, sociocultural norms hold women responsible for household water collection, requiring them to travel far distances while carrying water. This paper reports the findings of a scoping review of peer-reviewed and grey literature that examines the relationship between water fetching and the musculoskeletal (MSK) health of women in SSA. The work is informed by a gendered life-course perspective, and the authors follow the PRISMA-ScR guidelines. Results indicate a bidirectional relationship between water fetching and poor MSK health as chronic and acute incidences of water carrying are highly related to MSK pain and dysfunction. This has negative implications for the overall health and wellbeing of women and their households. Gaps in the literature are identified, including the experiences of elderly people and people with various vulnerabilities. Recommendations from the literature are compiled to outline potential avenues of future research and innovation to better support the MSK health of water fetchers in SSA.
Measurement System for the Calibration of Accelerometer Arrays
Authors: Pesti Richárd , Csík Dominik , Sarcevic Péter , Odry Ákos
Published: September 2024

This paper addresses accelerometer array calibration, focusing on determining the errors between multiple sensors. Micro-electromechanical system (MEMS) based triaxial accelerometers, key components of Inertial Measurement Units (IMUs), are used in localization, robotics, and navigation systems. The requirements of these applications necessitate low-cost sensors, which makes MEMS IMUs a reasonable choice. However, these low-cost IMUs are significantly affected by systematic (i.e., bias, misalignment, scale-factor) and random errors. Achieving reliable sensor output depends on the precision of the executed calibration method. While traditional laboratory-based sensor calibration using specialized equipment (i.e., three-axis turntable) is accurate, it is time-consuming and costly. In contrast, in-field calibration techniques, which can be performed using a mechatronic actuator or a robotic arm, have gained popularity. These techniques involve comparing sensor measurements to established reference values. The MEMS sensors are increasingly being used in multi-sensor applications, which demands not only individual sensor error calibration but also important to determine the axis misalignment between the used sensors. During calibration process, various optimization algorithms (e.g., GA, PSO) can also be used to find the error parameters. The proposed measurement system allows for individual calibration of misalignment, bias, and scale factor of the sensor array, and eliminates between-sensor misalignment errors.

Characteristics of Suspension or Full/Partial Refusal of Performance in Case of a Counterparty’s Failure to Perform an Obligation under Ukraine’s Civil Legislation
Authors: Leheza Yevhen , Shcherbyna Bogdan , Leheza Yulia , Pushkina Olena , Marchenko Olesia
Published: September 2024

The article explores the application of the right to suspend or fully or partially refuse to fulfill an obligation in the event of non-fulfillment of a counter-obligation by the other party. Scientific works of civilian classicists on obligation and research of Ukrainian civilian scientists served as material for study. The article distinguishes between conflicting and interdependent duties. It also highlights the issues of Part 3, Article 538 of the Civil Code of Ukraine, in case the buyer fails to fulfill the obligation to pre-pay for goods. The legal nature of the right to suspend or fully/partially refuse to fulfill a duty has been clarified: This is a way to protect civil rights and interests. Attention is drawn to the fact that the studied right can be exercised if the other party breaches a negative obligation. Ways to improve Ukraine’s legislation on the specified topic are proposed.
Comparative analysis of central aortic blood pressure, pulse wave velocity & arterial stiffness in patients with obstructive airway disease
Authors: Bajpai Jyoti , Pradhan Akshyaya , Bajaj Darshan Kumar , Verma Ajay Kumar , Kant Surya , Sethi Rishi
Published: September 2024

Background

As the pulmonary system and cardiovascular system are intimately linked, patients with chronic obstructive pulmonary disease (COPD) and asthma have high risk for developing cardiovascular diseases (CVDs) and altered central hemodynamic.

Objective

We aim to assess the central aortic blood pressure (CABP) indices, pulse wave velocity (PWV) and other indicators of arterial stiffness in Indian patients with COPD and bronchial asthma.

Methods

This is a single‐center, cross‐sectional study conducted in outpatients diagnosed with either chronic stable phase of COPD or bronchial asthma. CABP indices, vascular age, arterial stiffness and central hemodynamics were measured in patients.

Results

Of 193 patients with obstructive airway disease who were enrolled, (n = 81 had COPD and n = 112 had partially‐controlled bronchial asthma) the proportion of male patients was higher in both groups. The PWV, augmentation index (AI) and vascular age (VA) were significantly higher in patients with COPD compared to those with bronchial asthma (all, p < 0.05).

Conclusion

The study showed that PWV, AI and VA were higher in patients with stable COPD without any cardiac comorbidities compared to bronchial asthma.
Touching the Franks Casket: Global History and the Trojan Past on an Early Medieval English Object
Authors: Hartmann Jan-Peer , Johnston Andrew James
Published: September 2024

The contribution examines the Franks Casket, a whale-bone casket probably produced in the northern British kingdom of Northumbria in the eighth century that displays a number of carved images referencing events from different cultural and temporal contexts as well as inscriptions in Roman script and runes, Latin and Old English. We focus on the casket’s lid, which shows a siege scene, with an archer prominently displayed towards the middle, the word ægili carved above him. Traditionally understood as a reference to an unknown story about Weland’s brother Egil, the image has also been read as a depiction of the siege of Troy by a minority of scholars. While we offer evidence that the latter reading is at least somewhat better founded than the former, we argue that the lid’s design does not necessarily invite a straightforward identification with a single cultural context but rather works as a hinge that ties together the various cultural and temporal references on the casket. In allowing the viewer to construct various contexts in which the image might be viewed, the Franks Casket suggests their fundamental compatibility, as if the supposedly distinct historical and legendary materials had always overlapped and permeated each other. Taking into account the object’s material and aesthetic form thus makes it possible to break away from all-too-simple narratives of historical succession and helps us understand the complex temporalities that early medieval English art was capable of generating.
Touching the Shield of Achilles: Ekphrasis and/as Re-Mediation
Authors: Shohet Lauren
Published: September 2024

Homer’s treatment of the Matter of Troy illuminates the foundational impossibility of representation in ways that sponsor examination of the semiotic choices, the costs and benefits and tradeoffs, of different practices. Homer’s ekphrastic description of the shield of Achilles highlights a variety of available semiotic systems focused on different media of representation. This article explores Homeric ekphrasis in relation to later theories of media intersection, interaction, and transformation. Not only word, image, music, and dance, but also human perception as such, are subject to mediation.
Defacing Troy: From Shakespeare’s The Rape of Lucrece to Medieval Manuscripts
Authors: Ravenhall Henry
Published: September 2024

Shakespeare’s 1594 The Rape of Lucrece recounts the eponymous character’s defacement of an image of the Fall of Troy. When reread in light of a widespread medieval practice of defacing images, including those in manuscripts about Troy, Lucrece’s act is not (solely) a metaphor or a literary device, but an indication of how visual matter could be touched in premodern Europe. Reciprocally, Shakespeare’s poem provides a rare glimpse of the complex affective and psychological dynamics behind medieval defacements of Troy (or otherwise), for which very little documentary evidence survives.

Agree, agreement dissociation and subject ellipsis. Towards a new characterization of the Null Subject Parameter
Authors: Saab Andrés
Published: September 2024

This paper offers a new characterization of the Null Subject Parameter (NSP). I contend that the NSP must be modeled referring to two main properties of theAgree/agreement systems: (i) presence/absence of abstractAgree, and (ii) presence/absence ofagreement dissociationat PF. The first property results in the division between radical argument ellipsis languages of the Japanese type and consistent null subject languages of the Spanish type, including languages like Central Trentino, i.e., languages with some obligatory clitic subjects but with rich agreement and free inversion. The second property results in the division between consistent null subject languages and consistent non-null subject ones. The agreement dissociation hypothesis also accounts for the partial null subject type, which characterizes languages like Brazilian Portuguese that have impoverished agreement expansion at PF (perhaps, only for number features). From a theoretical point of view, this study focuses on the agreement dissociation property showing why abstractAgreecannot guarantee subject ellipsis even in those perplexing cases in which it produces enough agreement distinctions at PF. The reason is that only an expanded agreement morpheme adjoined to the T0node can serve as a licit antecedent for ellipsis of a subject D0head at PF. Therefore, the theory derives the bimorphemic principle in Koeneman and Zeijlstra (Koeneman, Olaf & Hedde Zeijlstra. 2021. Pro-drop and the morphological structure of inflection. Ms. Available at:https://www.heddezeijlstra.org/bio) without further ado, i.e., the observation that null subject properties correlate with a bimorphemic T0node expressing tense and agreement separately.

Authors: Koparan Arzu , Dede Süreyya , Işıksaçan Nilgün , Yeşilbağ Zuhal , Karakuş Emine
Published: September 2024

Objectives

The presence of live SARS-CoV-2 viruses in the fecal specimens and the positive results for SARS-CoV-2 RNA in gastrointestinal samples after respiratory specimens had become negative indicate that there may be a risk of transmission of the disease not only through the respiratory tract but also through the fecal-oral route. The study aim is to determine the time period that the SARS-CoV-2 virus remains in the fecal specimens of discharged COVID-19 patients to reveal the time interval in which the risk of transmission continues.

Methods

In 65 patients hospitalized with a COVID-19 diagnosis, the viral RNA was isolated from the supernatant of the stool sample using CVXTM viral RNA extraction kit. The extracted RNAs from the stool samples were detected using a commercial RT-PCR method.

Results

Positive results were obtained in the stool samples in eight of sixty-five patients and the presence of SARS-CoV-2 in these patients was detected for up to three weeks.

Conclusions

By determining the residence time of SARS-CoV-2 virus in stool samples of discharged COVID-19 patients, the time interval during which the possibility of transmission risk continues has been revealed. The findings of the study could prove beneficial in comprehending the risks of transmission and translating them into preventative measures.
Computation Legendre moments using image analysis technique
Authors: Mallika Karamcheti , Vijaya Lakshmi K. , Lakshmi Sarada K. , Sreehari Sastry S.
Published: September 2024

In this paper, phase transition temperatures of nematic liquid crystals: 4-n alkoxy benzoic acid (nOBA, where n = 4 and 6) are determined from the Legendre moments of liquid crystal textures. Here, the image analysis technique in conjunction with polarizing optical microscope is used to compute the Legendre moments from the textures of liquid crystals. As a function of temperature, Liquid crystal textures are recorded from the arthroscopic mode of optical microscope. Changes in textural features of the sample with respect to temperature bring the variations in intensity values of liquid crystal textures. The brightness image that is generated from the liquid crystal textural patterns separates the information about fluctuations in intensity. In this approach, Legendre moments are computed from the brightness images of the liquid crystal textures and are plotted as a function of temperature. Significant variations in the brightness Legendre moment curve provide insight into the liquid crystal transition temperatures. Results obtained from the present methodology are compared with gray color textures data and the experimental technique of differential scanning calorimetry and are in good agreement with each other. This method is an objective and quantitative technique whereas POM method is qualitative and subjective.
Interferencia morfosintáctica del quechua al castellano en la provincia del Cusco
Authors: Condori Pauccara José
Published: September 2024

The Spanish spoken in the province of Cusco belongs to Andean Spanish, this because of the linguistic contact between Quechua and Spanish. This linguistic relationship generates various linguistic cases such as bilingualism, interference, substitution of one language for another, etc. The objective of this investigation is to describe and analyze the morphosyntactic interference from Quechua into Spanish spoken by bilinguals in the province of Cusco. The methodology used the qualitative approach and, consequently, the descriptive explanatory method. The linguistic corpus is made up of the information noted in the linguistic record sheet and the series of recordings of the interview. Also, the techniques that were used were observation andthe interview.The instruments used were the linguistic record sheet and a semi-structured questionnaire for the interview. The study design is of a non-experimental, cross-sectional nature. The results obtained show that morphosyntactic interference from Quechua to Spanish is manifested in linguistic insertion, omissions, grammatical substitutions, grammatical discordance, and solecism. Finally, the linguistic cases analyzed are natural expressions of the bilingual, without taking into account whether the bilingual is a native or non-native speaker.
Interculturalidad y bilingüismo: entre el normativismo funcional y las posturas emergentes en el diseño curricular oficial de formación docente en educación intercultural bilingüe en el Perú
Authors: Chávez Gonzales Oscar
Published: September 2024

The purpose of this article is to review the educational approaches to interculturalism and bilingualism in the intercultural bilingual education (IBE) syllabus of the National Basic Curriculum Design (DCBN) for initial teacher education (ITE). The Peruvian State, faced with the cultural and linguistic diversity expressed in 55 native peoples who communicate in 48 languages, applies IBE policies to the students from these peoples with teachers who have a higher education. Through documentary analysis, the information was organized to describe, analyze and interpret using categorization and codification by means of the deductive-inductive criterion. The results highlight the effort of the official document to incorporate interculturalism and bilingualism approaches, including the contributions of current trends. The relevance of normative-functional interculturalism is a proposal of the ITE only for indigenous people, since this curricular design, due to its national scope, has limitations to interculturalize teacher training from a more critical stance. When dealing with native languages in IBE and Spanish, it strives for technical-curricular goals of oral and written skills, neglecting the rescue and recovery of the oral, written or textualities of indigenous peoples, ignoring their social and dynamic use.

Gerty Cori was the first woman awarded the Nobel Prize in Physiology or Medicine, the first woman the Nobel Prize laureate in the United States, and the third woman the Nobel Prize laureate worldwide following Marie Curie-Skłodowska and her daughter, Irene Joliot-Curie. Despite a challenging and lengthy path to recognition, Gerty Cori’s exceptional qualities and strong character led to her success. In 1947, she was awarded the Nobel Prize in Physiology or Medicine jointly with her husband and lifelong research partner Carl Cori “for their discovery of the course of the catalytic conversion of glycogen”. The Nobel Committee recognized this discovery as one of the most outstanding achievements in biochemistry. Keywords: adrenaline, Cori cycle, diabetes, glucose, glucose-1-phosphate, glucose-6-phosphate, glycogen, hexokinase, insulin, Nobel Prize, phosphoglucomutase, phosphorylase

Con el uso creciente de las redes sociales, personas no autorizadas han conseguido detectar o interceptar datos personales, que podrían utilizarse de manera inapropiada, causando así daños personales. Por lo tanto, es esencial utilizar un mecanismo de seguridad que ayude a proteger la información de ataques maliciosos. En este trabajo se propone el reconocimiento facial, utilizando las características texturales locales de los criptogramas. Se cifraron imágenes faciales en formato Red-Green-Blue (RGB) aplicando el modelo matemático de Mapa Logístico, lo que generó un criptograma. Las características texturales locales de estos criptogramas se extrajeron mediante la transformación de representación de cluster coordinado (CCR). La alta eficiencia de clasificación (97-100%) de las imágenes faciales cifradas fue validada experimentalmente utilizando dos bases de datos: la primera fue generada controlando parámetros como la rotación, escala e iluminación; y la segunda es una base de datos pública. Esta técnica es adecuada para una amplia gama de aplicaciones relacionadas con la autenticación de usuarios, y protege la identidad de los usuarios autorizados cuando se acompaña de capas adicionales de seguridad que involucran imágenes de interés, como las utilizadas en el campo médico, mejorando la seguridad de los usuarios cuyas enfermedades se estudian gráficamente en los hospitales. Además, esta técnica puede desplegarse para proteger lanzamientos de nuevos productos donde las imágenes son importantes, como ropa, calzado, mosaicos, etc., ya que no es necesario descifrar las imágenes para clasificarlas.
A turizmus környezetbiztonsági aspektusai: holisztikus megközelítés
Authors: Michalkó Gábor , Németh József , Birkner Zoltán
Published: September 2024

A környezetbiztonság a turizmusbiztonság mindeddig kevesebb figyelmet élvező azon tényezője, amely a többi biztonságfaktorra is érdemi hatást gyakorolva képes növelni az utazások észlelt vagy valós kockázatát, illetve veszélyét. Környezetbiztonság alatt értünk minden olyan tényezőt, amely alapvetően a Föld belső és külső erőivel, az élő és élettelen természettel áll összefüggésben, és puszta léte vagy annak változásai fenyegetettséget jelentenek a turizmusipar eredményes működésére. Mivel a szakirodalom mindeddig adós maradt a turizmusbiztonság környezeti aspektusainak holisztikus tárgyalásával, a tanulmány arra vállalkozik, hogy elméleti keretbe ágyazva, a jelenségek és folyamatok megértését elősegítendő modelleket alkotva és egy archetipikus esettanulmány felhasználásával rendszerszerűen mutassa be a természeti környezet és a turizmus nexusának biztonsági vonatkozásait.
A turizmus egészséggel összefüggő környezetterhelése
Authors: Uzzoli Annamária
Published: September 2024

A gyógyturizmushoz kötődő környezeti kihívások döntően a természeti erőforrások kiaknázásán és a szolgáltatásokkal összefüggő hulladékképződésen keresztül jelentkeznek. A meglehetősen kevéssé kutatott téma a fenntartható fejlődés és az utazásorvostan határmezsgyéjén helyezkedik el, alapvetően a különböző betegségekkel utazó emberek viselkedéséből és az utazási betegségekből fakadó környezetterhelés kérdéskörét fogja át. A problémára a Covid– 19-világjárvány hívta fel a figyelmet. A tanulmány célja, hogy különböző területi szinteken áttekintést adjon a turizmus egészséggel összefüggő tevékenységeinek környezetterhelésre és környezetbiztonságra vonatkozó következményeiről. Az elsősorban szakirodalmi feldolgozásra épülő vizsgálat egyúttal leíró statisztikai elemzést is magában foglal. A tanulmány olyan, eddig kevesebb figyelmet kapott egészségügyi aspektusokra hívja fel a figyelmet, amelyek számottevően befolyásolhatják az utazás és a környezet szimbiotikus biztonságát.

A Covid–19-világjárvány megfékezésére bevezetett korlátozások és utazási tilalmak szinte egyik napról a másikra lehetetlenítették el a turizmust. Jelen tanulmány célja, hogy az Európai Élelmiszer-biztonsági Hatóság (EFSA) jelentése alapján képet adjon az utazáshoz kapcsolódó, élelmiszer-eredetű megbetegedésekről. A Covid–19 miatti korlátozások enyhítése és a konszolidálódó turizmus következtében 2022-ben az utazással összefüggő – állatról emberre terjedő, élelmiszer-eredetű – megbetegedések száma az előző évhez képest növekedést mutatott, a két legjelentősebb megbetegedés esetében azonban a világjárvány kitörése előtti szintnek csak nagyjából felét érte el. Tanulmányunkból a négy legjelentősebb fertőzés esetében az utazással összefüggő megbetegedések és a megbetegedésekben érintettek származási országai is kirajzolódnak.
A természeti erők okozta katasztrófák hatása a turizmusra: Esettanulmányok
Authors: Mátyás Szabolcs , Tóth Antal
Published: September 2024

Magyar és idegen nyelvű szakirodalmakból kiválasztott gyakorlati példák bemutatásán keresztül azt vizsgáltuk, hogy a természeti erők okozta katasztrófák milyen hatással vannak a turizmusra. A katasztrófákat két csoportba soroltuk: megkülönböztettünk belső és külső erők okozta katasztrófákat (ezek a most vizsgált, szűkebb értelemben vett természeti katasztrófák), valamint antropogén eredetű eseményeket. Az előbbiek öt nagyobb kategóriáját különítettük el: geológiai jellegű katasztrófák, geomorfológiai jellegűek, hidrológiai események, meteorológiai/klimatológiai katasztrófák és kozmikus veszélyek. Az esettanulmányok feldolgozása során pozitív megerősítést kapott az a kutatási hipotézisünk, miszerint a természeti katasztrófák igen jelentős, általában – de nem kizáró módon – negatív hatással vannak a turizmusra.

In the confectionery industry large quantities of palm fat in the fillings of chocolate products are used. Based on today's nutritional science results, it is desirable to replace palm oil with healthier fats. Oleogels can provide a kind of solution for this replacement. In our work the rheological, textural and thermal properties of oleogels containing high oleic sunflower oil, beeswax and monoglycerides were determined. In the samples we examined, the gelator concentrations were: 20% beeswax, 15% beeswax and 5% monoglyceride, 10% beeswax and 10% monoglyceride, 5% beeswax and 15% monoglyceride, and 20% monoglyceride. Based on our results, the oleogel containing 15% beeswax and 5% monoglyceride seems an eutectic crystal of beeswaxes and monoglyceride. It has relative high hardness, high storage modulus and high viscosity therefore it can replace the Chocofill filling fat, which contains mainly palm fat, used in large quantities in sweets.
“This Musical Peace is Worse than War:” Cultural History, Musical Banality and Political Context in the Ballet Excelsior
Authors: Ujvári Hedvig
Published: September 2024

From 1847, the head of the Budapest ballet was Federico Campilli (1820–1889), an individual of Italian origin. He regarded Viennese taste as authoritative in designing the program, thereby building on the international ballet repertoire. This repertoire included romantic pieces from Western Europe, along with Campilli's own choreographies. Campilli concluded his forty-year tenure in Budapest in 1887, and Cesare Smeraldi (1845–1924) assumed his position. The imperial city served as the model for shaping the ballet program, commencing its operations with the staging of Manzotti's spectacular Excelsior, which had premiered in Vienna two years earlier. This sensational performance, focused on the rise of human civilization and the development of technology, involved hundreds of actors and was destined for success throughout Europe. It ran for 29 years in Vienna and nine years in Budapest. In this study, an exploration of the driving forces behind this ballet success story with unconventional themes is undertaken. Various aspects are examined, such as the discourse of dance and the articulation of otherness in local and global spaces. The study delves into what technophile ballet entails, how cultural history, abstract concepts, discoveries, and inventions can be narrated through ballet. The thesis also highlights the debatable aspects of the ballet's music, utilizing music reviews from Budapest and Viennese newspapers. Through these reviews, an attempt is made to map the reception history of the ballet in Vienna and Budapest. The significance of Excelsior in the political power field within Hungarian conditions is also emphasized.

Introduction: Total Knee Replacement (TKR) is a final therapeutic recourse for knee  osteoarthritis (OA) when conservative treatments are ineffective. Tourniquet application  can precipitate complications, including an augmented inflammatory response  characterized by elevated levels of IL-6 due to tissue trauma during surgery and ischemic
reperfusion. This study aims to assess the changes in MDA, IL-1, and IL-6 levels before  and after 15 minutes of tourniquet application and to investigate their correlation with the  duration of tourniquet use.
Methods: This study used a longitudinal observational with a repeated cross-sectional  design. The sample for this study consisted of patients who underwent TKR at Prof. Dr.  IGNG Ngoerah Hospital and met the inclusion and exclusion criteria set by the researchers. Results: This study found that there was a significant increase before and after 15 minutes  of the tourniquet use in MDA levels (3.22; SD 0.5), IL-6 (64.18 + 19.40) but not significant  IL-1 (65.86; SD 19.60). With the Spearman correlation test, there was no significant  correlation between the duration of tourniquet use with an increase in IL-6 levels (r = 0.27,  p> 0.05) and an increase in MDA levels (r = -0.21, p> 0.05), with an increase in IL-1 levels  (r = 0.442;(p> 0.0 .5) respectively.
Conclusion: The study found increased levels of MDA, IL-1, and IL-6 before and after 15  minutes of tourniquet use, but no correlation with duration of use. Inflammatory mediators  persist locally during ischemia-reperfusion; IL-6 peaks up to 24 hours post-tourniquet  release, suggesting delayed systemic effects beyond the studied timeframe.
