Abstract
Metastasis significantly contributes to the poor prognosis of advanced nasopharyngeal carcinoma (NPC). Our prior studies have demonstrated a decrease in BIRC5-206 expression in NPC, which promotes disease progression. However, the role of BIRC5-206 in the invasion and metastasis of NPC has not been fully elucidated. In this study, our objective was to explore the biological function and underlying mechanisms of BIRC5-206 in NPC. Additionally, we established an NPC mouse model of lung invasiveness using C666 cells to assess the impact of BIRC5-206 on NPC metastasis. Our results revealed that silencing BIRC5-206 inhibited apoptosis and enhanced the invasion of NPC cells, whereas its overexpression reversed these effects. Moreover, decreased BIRC5-206 expression significantly increased N-cadherin and Vimentin expression while reducing E-cadherin and occludin levels, both in vivo and in vitro. Additionally, silencing BIRC5-206 markedly augmented the formation of invasive foci in lung tissues. Rescue experiments further confirmed that decreased BIRC5-206 expression facilitates NPC metastasis via modulation of the miR-145-5p/CD40 signaling pathway. In summary, our study suggests that BIRC5-206 may serve as a potential prognostic biomarker and therapeutic target in the diagnosis and treatment of NPC.
Relational or Object-Oriented? A Dialogue between Two Contemporary Ontologies
Authors: Sandru Adrian Razvan 
Published: September 2024

Abstract
Graham Harman’s Object-Oriented Ontology (OOO) emphasizes the autonomy of objects, positing a withdrawn surplus of being that resists reduction to its parts or the sum of its parts. However, Harman’s framework faces conceptual tensions, including challenges in reconciling epistemological and ontological dimensions, explaining the formation of compound objects, and ascribing determinate features to experientially inaccessible objects. I argue that these issues arise mostly due to Harman’s over-commitment to a withdrawn substantial core of objects. To address these issues, I propose turning to Jean-Luc Nancy’s post-phenomenological materialism and Alain Badiou’s mathematical realism. Both Nancy and Badiou offer alternatives to Harman’s substantialist core, emphasizing a local, contextually bound identity of things, which describes a restricted domain from the endlessly broader horizon of relations and situations in which each thing is or can be involved. They thus account for the surplus of being in each thing and consequently their ontological autonomy without recourse to a substantive grounding. I argue such a relational-friendly account of pluralism avoids the conceptual issues Harman’s OOO runs into. Lastly, I emphasize the value of OOO as an advocate for ontological equality that seeks to avoid the emergence of privileged actors or centralized discourse. This dialogue between Harman, Nancy, and Badiou thus seeks to advance the possibility of pluralistic ontologies within relational frameworks, combining the perspectives of OOO with post-phenomenological theories to explore the complexities of relationality without recourse to non-relational substrata.
„In tyrannos“ !? – Sicco Polentons Ovidvita zwischen mittelalterlichem ‚Aberglauben‘, ‚republikanischem Diskurs‘ und pragmatischem Bildungsideal
Authors: Meins Friedrich 
Published: September 2024

Abstract
The paper offers a new interpretation of the Life of Ovid in the Scriptorum illustrium Latinae linguae libri XVIII of Sicco Polenton. While so far scholarship has mostly criticized the lack of historical and philological accuracy in this Life and Sicco’s dependency on medieval speculations, the paper tries to take a closer look at the implications of Sicco’s own methodological stance towards poetry, historiography and rhetoric. A discussion follows whether Sicco’s own biography has shaped his outlook on the ancient poet, and to what extent Sicco’s treatment of Ovid’s relegation can be integrated into an early humanist tradition of anti-tyrannical discourse. It is argued that both Sicco’s literary ideals and the elaboration of the Life of Ovid, especially the description of the exile, reflect Sicco’s own life story and social background, but also his fundamental purpose of promoting his humanistic teaching.
Empirical investigation and performance evaluation of flat-plate solar water heating systems: a comparative analysis with and without heat exchangers

Published: September 2024

Abstract
Harnessing solar energy through flat-plate solar water heating systems offers an efficient and sustainable solution for residential water heating needs. This study aims to assess and compare the thermal efficiency of two flat-plate solar water heating systems designed for residential use: one with a heat exchanger and one without. Each system features a flat-plate collector with a dark absorber, a transparent cover to reduce heat losses, and a heat-transport fluid. A thin copper sheet with a selective coating forms the absorber. According to the standards of the Indian Ministry of New and Renewable Energy (MNRE), the evaluation revealed that the system without a heat exchanger achieved a higher efficiency (50 %) compared to the system with a heat exchanger (46 %). This device demonstrated notably lower thermal loss efficiency relative to previous studies, as evidenced by heat loss coefficients of 2.89, 2.66, 1.77, and 2.13 W/m2 k. Despite the higher efficiency of the system lacking a heat exchanger, the importance of heat exchangers in mitigating issues related to water hardness must be acknowledged. This study offers novel insights into the design and optimization of solar water heating systems, highlighting the trade-offs between efficiency and practical considerations.

Batik is the art of drawing on cloth using canting with small ends and batik wax. The process of making batik can cause work accidents and occupational diseases that occur because of equipment failure and human errors that do work not according to procedures. However, in the informal batik industry, there still needs to be more knowledge and awareness related to potential hazards and controls that must be carried out. Therefore, it is necessary to conduct education to increase workers' understanding and create a safe and comfortable work environment. This research method is a quantitative study using the Wilcoxon Test to compare observations before and after treatment and determine the effectiveness of treatment. Based on the observations and analysis that have been carried out, it can be concluded that there is a significant relationship between the use of safety cards.

На основе результатов исследований фазовых равновесий компонентов тройной системы глубоких эвтектических растворителей (ГЭР) “глицерин - карбамид - борная кислота” создана композиция, характеризующаяся регулируемыми физико-химическими параметрами в широком диапазоне. Изучено влияние полученной композиции на увеличение нефтеотдачи пластов, а также представлены результаты лабораторных исследований влияния композиции на основе ГЭР на фильтрационные характеристики неоднородного пласта карбонатного коллектора Усинского месторождения. Методом физического моделирования произведена оценка эффективности композиции для месторождений, находящихся на ранней и поздней стадиях разработки. Установлено, что обработка модели неоднородного пласта композицией приводит к существенному приросту коэффициента нефтевытеснения как при низких, так и при высоких температурах за счет выравнивания фильтрационных потоков, увеличения охвата пласта и восстановления начальной проницаемости. Исследование состава и свойств тяжелой высоковязкой нефти до и после обработки композицией показало, что применение кислотной композиции на основе ГЭР не влияет на качественный состав нефти. Использование композиции приводит главным образом к перераспределению содержания низко- и высокомолекулярных структур: вытесняются преимущественно легкие окклюдированные углеводороды, в то время как тяжелые компоненты нефти адсорбируются на коллекторе.
A composition characterised by adjustable physicochemical parameters within a broad range has been developed relying on the results of studies of the phase equilibria in the ternary system of deep eutectic solvents (DES) glycerol - carbamide - boric acid. The effect of this composition on oil recovery enhancement is studied, and results obtained in the laboratory studies of the effect of DES-based composition on the filtration characteristics of a heterogeneous formation in the carbonate reservoir of the Usinsk field are presented. The efficiency of the composition for oilfields at the early and late stages of development has been assessed by physical modelling. The treatment of a model of a heterogeneous reservoir with the composition is determined to cause a substantial increase in oil displacement coefficient at either low or high temperatures due to equalisation of filtration flows, an increase in reservoir coverage, and restoration of initial permeability. Investigation of the composition and properties of heavy high-viscosity oil before and after treatment with the composition shows that the application of DES-based acid composition does not affect the qualitative composition of oil. The use of the composition leads mainly to redistribution of the content of low- and high-molecular structures: predominantly light occluded hydrocarbons are displaced, while heavy oil components are adsorbed on the reservoir.

Реконструирована история деградации оледенения в бассейне высокогорного озера Сылтранкёль (Приэльбрусье, Северный Кавказ) с конца XIX до конца XX в. В 2022 г. произведено комплексное обследование котловины озера, включавшее отбор отложений и их последующее радиоизотопное датирование, анализ структур, текстур и гранулометрического состава, подсчет варв. Параллельно проанализирована совокупность литературных источников, топографических карт, наземных фотографий, космо- и аэрофотоснимков и собственных полевых наблюдений для определения положения краев ледников на разных временных этапах. Выделены четыре этапа в формировании донных осадков, коррелирующие с состоянием горного оледенения и изменениями конфигурации озерного водосбора. Сходимость результатов, полученных на основании независимых источников, подтверждает высокую методическую ценность исследования донных осадков горных озер как одного из немногочисленных архивов природной среды, фиксирующих изменения оледенения в динамичных природных условиях высокогорий.
Deglaciation history of the Syltrankel high-mountain lake basin (Mt. Elbrus region, Northern Caucasus) from the end of the 19th to the end of the 20th centuries was reconstructed. In 2022, a comprehensive examination of the area was carried out, including sampling of the bottom sediments and following radioisotope dating, structural and textural analysis. Simultaneously, a set of published sources; topographic maps; ground, satellite, and aerial photographs; and field observations was analyzed to determine the positions of the edges of glaciers at different times. In the formation of bottom sediments, four stages were identified correlating with the state of mountain glaciation and changes in the configuration of the lake’s drainage area. Converging results obtained on the basis of independent sources indicate the high methodological value of studying bottom sediments of mountain lakes as one of the few environmental archives that record glaciation changes in the dynamic conditions of high mountains.

Published: September 2024

Вычисление инсоляции Земли с высоким пространственным и временным разрешением позволило рассчитать солярные характеристики, отражающие изменение астрономических факторов, регулирующих вариации приходящей солнечной радиации и изменение интенсивности переноса радиационного тепла (меридионального, в системе “океан-материк”, межполушарного). В соответствии с этим в масштабах голоцена проведена модернизация астрономической теории изменения климата. На основе синхронизации глобальных климатических событий с экстремумами солярных характеристик в голоцене и позднем плейстоцене предложен метод солярной геохронологии, позволяющий уточнять хронологию глобальных климатических событий и объяснять их генетическую природу.
The calculation of the Earth’s insolation with high spatial and temporal resolution made it possible to calculate solar characteristics reflecting changes in astronomical factors regulating variations in incoming solar radiation and changes in the intensity of radiative heat transfer (meridional, in the ocean-mainland system, and interhemispheric). Following this, the astronomical theory of climate change has been modernized on the Holocene scale. Based on the synchronization of global climatic events with extremes of solar characteristics in the Holocene and Late Pleistocene, a method of solar geochronology is proposed, which makes it possible to clarify the chronology of global climatic events and explain their origin.

The European response to Russian disinformation in the context of the war in Ukraine
Authors: Bayer Judit 
Published: September 2024

AbstractDisinformation and propaganda directed at foreign countries is an important tool in Russia's geopolitical power ambitions, including its war against Ukraine. The European Union and individual nation states, both inside and outside the Union, have developed complex responses to this multifaceted phenomenon. This article focuses on just one of them: the EU embargo on the RT television channel. It will review media analyses of RT, some of the legal action taken against it, and analyse the background and rationale behind the EU's blocking regulation. It points out that, while international media law literature has examined the issue from the perspective of freedom of expression, the European Union has treated the channel as a political weapon. The article argues that democracies need to take decisive action to defend their structures, and that this may require unconventional measures in times of disruption to the international order.
War shock and the economy
Authors: Halmai Péter 
Published: September 2024

AbstractThe main features of war shock are substantially different from those of the preceding COVID-19 shock. The EU economy is showing important elements of resilience. The existing structural forces and adaptive capacity of the EU economy are clear indications that it is capable of transformation and avoiding recession.The dynamics of the war is also crucial in terms of economic impacts. There are still many uncertainties about the future course of the war and its ramifications. The fundamental question is whether the war is heading in the direction of escalation or de-escalation. Unless the war spreads beyond Ukraine and the conventional means of warfare, its global economic consequences may be limited after the initial shock. New adjustment processes in the field of green and digital transition can be set in motion in parallel with the suffering and turmoil of war shock. New market players could emerge in the energy markets.The prolonged war continues to challenge the Ukrainian economy, but it can remain viable with massive external support. The Russian economy could suffer serious erosion, with its comparative advantage being wasted.There is a real threat of deglobalisation and the emergence of a fragmented world economy, but the counteracting factors appear to be much stronger. However, the prolonged war continues to pose major and unpredictable threats to the countries affected directly and indirectly, to Europe and to the world economy.

Current problems of applying tax incentives for organizations in the IT industry
Authors: Boltinova O. V. , Sorokin A. A. 
Published: September 2024

The article is concerned with the application of tax benefits established for organisations in the field of information technology. The article analyses the conditions for the application of manoeuvre benefits in the IT industry. For the purposes of the research, the authors consider topical problems related to the qualification of certain types of revenue in the income from the IT activities. In addition, the authors formulated a proposal to improve the legislation in this area.It is pointed out that income from IT activities does not include income received from the use of computer programmes and databases connected with the receipt of banking and financial services. However, the legislation of the Russian Federation does not contain a precise definition of the concept of “financial service” and there is no concept of “banking service” at all.
