The preclinical surgically-induced models of myocardial infarction (MI) have been extensively utilised for studying the wound healing response in the mammalian heart. It is well-established that these invasive procedures induce marked acute systemic inflammation and adverse haemodynamic derangements, which can result in extra-cardiac tissue injury and remodelling; however, the extent of this has not yet been robustly characterised. Here, using a rat permanent coronary artery ligation (PL) model of MI and the cis- and trans-4-[18F]fluoro-l-proline positron emission tomography (PET) probes, targeting active misfolded and triple-helical collagen biosynthesis, respectively, we conducted an exploratory time-course analysis of the associated extra-cardiac tissue remodelling post-injury. Our results showed an increased cis-4-[18F]fluoro-l-proline PET signal in the liver (P = 0.02; two sample t-test) and lung (P = 0.03; two sample t-test) at the acute day 7 timepoint in the MI group compared to the Sham group (n = 3-6), which was not apparent at the later timepoints (days 14, 28, and 84). Ex vivo quantification of the deposited collagen in extra-cardiac tissues using Sirius red histochemical staining and the total hydroxyproline assay validated the apparent time course trends observed with [18F]fluoro-l-proline PET. These findings suggest that the liver and lungs are susceptible to acute injury in the rat PL model of MI and align with numerous clinical reports of extracardiac injury in MI patients. Moreover, our results highlight the suitability of [18F]fluoro-l-proline PET as a systems-based imaging technique for investigating active collagen biosynthesis across multiple organs.

Authors: Diva Imelda Putri 
Published: October 2024

Line Follower is a robot that follows a line, and in it there is an Integrated Circuit that contains programming to run it. In this experiment, the line follower using fuzzy logic control provides another alternative in the control system. In fuzzy logic control, there is no need for a mathematical model of the system because fuzzy logic control works based on rules. The designed control is a one input, two output system and uses the Mamdani system as an inference mechanism. The output error in the program will increase when the robot turns to follow the trajectory, the error can occur due to the calculation of the membership function input and rules as a determinant of robot action when detecting the trajectory in front of it. Therefore, in this line follower experiment, the rule will be a reference in processing the input value of the distance and speed of the right and left motors, the rule also determines the direction of the robot using the help of a camera sensor.

Penggunaan Set Top Box bekas dengan diinstall sistem operasi OpenWRT sebagai gateway VPN tunnel untuk melakukan kontrol dari jarak jauh serta sebagai mikhmon server yang digunakan untuk manajemen user hotspot dinilai sangat cocok karena biaya pemasangan murah dan memiliki banyak fungsi. Hasil dari penerapan penelitian ini didapatkan bahwa jaringan RT/RW NET di Desa laden dapat dikontrol dan dapat melakukan manajemen user dari jarak jauh melalui ZeroTier VPN dan mikhmon yang ada di dalam sistem operasi OpenWRT sehingga meningkatkan efektifitas admin jaringan dalam mengontrol dan melakukan maintenance jaringan.
Investment Decision Factors of Non-Fungible Tokens in the Czech Republic: Survey
Authors: Tichý Kryštof 
Published: October 2024

Abstract
Non-fungible Tokens (NFTs), represent a revolution in the digital ownership paradigm. NFTs are a kind of digital asset built on blockchain technology, most commonly the Ethereum blockchain, that validate the uniqueness and ownership of a unique digital item in question. Each NFT carries specific information or attributes that make it original and non-fungible. Unlike cryptocurrencies like Bitcoin or Ethereum, which are identical to each other, non-fungible tokens cannot be exchanged on a like-for-like basis making them non-fungible. NFTs are traded for cryptocurrencies via online trading platforms. Investment in NFTs can present a risky situation due to the large volatility of the assets in a quite short time. This article focuses on identification of key aspects that influence decision making process of potential investors who are considering buying non-fungible tokens as an investment tool in the Czech Republic. From the point of view of investment decision-making, the primary factors appear to be the expected income from the investment, its payback period, and the risk that the investor undertakes. It has been proven that there is a degree of dependence between gender and the mentioned decision-making factors. The research showed that men are more inclined to make decisions based on expected returns, while women are more likely to make decisions based on perceived risk.
Creative Upcycling Projects in Support of the Green Deal for Europe
Authors: Šírová Eva , Zbránková Magdalena 
Published: October 2024

Abstract
The circular economy plays an important role in delivering on the commitment set out in the Green Deal for Europe. One of its key priorities is plastics - an important material that is ubiquitous in the economy and everyday life due to its functions. The production, use, and consumption of plastics have a negative impact on the environment, generating greenhouse gas emissions and reducing the supply of non-renewable raw materials. The change towards a circular economy, which is intended to preserve the value of products and materials for as long as possible, is to be supported by a hierarchy of waste management methods. The priority is waste prevention, while reuse and recycling are other appropriate ways. The paper presents how the Liberec Region is managing to meet the commitments of the Green Deal for Europe. Every individual can contribute to the implementation by changing their thinking and creative approach. An example is the upcycling of a plastic bottle, where the bottle is not perceived as waste but as a material for creating a new product with a higher use value.

Authors: Krasnoperova A. B. , Svilam N. M. 
Published: October 2024

Introduction. The following study answers the question whether the “Polar Index” project is a reliable reflection of the development of the Russian Arctic region in the field of sustainable development. Within the framework of this scientific work, the analysis of the general methodology for calculating the "Polar Index" assigned to each of the companies operating in the Russian Arctic was carried out. The analysis made it possible to understand the logic of assigning an organization to one of the three groups, depending on how active its sustainable development policy is.Materials and methods. The materials used in the given article include studies of Russian scientists devoted to sustainable development of the Arctic region, as well as the materials published on the official web-sites of Russian energy companies. In terms of research methodology, the article pays special attention to event analysis aimed at identifying and interpreting key activities and projects that are implemented by Russian companies in the Arctic zone within the framework of sustainable economic, social and environmental development. In order to do this, three Russian energy companies of different levels of participation in the development of the region were selected. Next, for each of these companies, an analysis of its actions and development strategy regarding the Russian segment of the Arctic was carried out.Results of the study. The comparison of the assessment of Russian energy companies’ activities based on the Polar Index and the conclusions regarding the effectiveness of their activities obtained as a result of the event analysis proves that the Polar Index project indeed reflects the effectiveness of the activities of Russian companies in the Arctic region, as well as the degree of their involvement in sustainable development of the polar region in question, with a high degree of reliability.Discussion and conclusion. The research revealed Russian companies, the activities of which to a substantial degree comply with all the three criteria of sustainable development, namely, economic, ecological, and social. That being said, relevant scientific research on the given subject demonstrates that the companies, which managed to achieve the best results in the given sphere, are Rosneft, Norilsky Nikel and Gaspromneft.
UK Labour Party Leaders' Attitudes to Conventional Threats to National Security, 2023-2024
Authors: Pankov E. S. 
Published: October 2024

Introduction. The article focuses on the securitisation of power threats in the public speeches of the UK Labour Party leaders (Prime Minister Keir Starmer, Defence Minister John Healey and Foreign Secretary David Lammy) during the 2023-2024 election campaign. An attempt has been made to highlight the commonalities and peculiarities in the approach of the current and previous British governments to countering the main threats to national security. Materials and methods. The paper combines qualitative and quantitative approaches: a critical content analysis of sources and discourse analysis in an electoral context (using data from sociological surveys) are conducted, while the frequency of word usage in the public speeches of the Minister of Foreign Affairs is analysed using the tools of quantitative analysis of big data (R programming language). The methodological basis of the work is the theory of securitisation proposed by the Copenhagen School of the theory of international relations.Research results. It is concluded that the main change in London's foreign policy after Labour's victory in the 2024 parliamentary elections will be the prioritisation of security cooperation with European states. Labour Party leaders do not question the need for ‘dual containment’ of Russia and China, but they give the ‘China threat’ secondary importance: there are noticeable differences within the party on this issue. On the other hand, Labour's position on the ‘special relationship’ with the United States is characterised by a steady continuity with the Conservative government's approach. The need to deepen cooperation in Euro-Atlantic security structures (primarily NATO) and continental formats (EI2, JEF) is stated.Discussion and conclusion. On the basis of qualitative examination of policy documents and statements of the Labour Party leaders, as well as quantitative analysis of big data, conclusions are drawn about the key elements of potential continuity and variability in the foreign policy of London before and after the parliamentary elections on July 4, 2024. The results of the work can be useful in forecasting changes in the foreign policy of Great Britain after the victory of Labour in the parliamentary elections of 2024. The theoretical importance of the work lies in the fact that the article proposes a new methodology for quantitative analysis of the foreign policy of the UK.

Permasalahan umum di sub-DAS Sekayam adalah meluapnya sungai saat curah hujan tinggi disebabkan nilai koefisien limpasan meningkat yang dipengaruhi perubahan tata guna lahan dimana perkebunan yang semakin meningkat. Informasi Tutupan lahan sangat penting digunakan untuk menghitung koefisien limpasan/pengaliran (C) sebagai salah satu indikator kerusakan DAS. Sehingga dilakukan penelitian ini untuk menghasilkan peta tata guna lahan serta mengkaji perubahan tata guna lahan terhadap nilai debit banjir dari rentang tahun 2012-2022. Perhitungan koefisien C dilakukan dengan metode U.S. Forest Service, metode Hassing, dan Nilai Koefisien C (Kodoatie & Syarief, 2008). Untuk perhitungan debit banjir rencana menggunakan metode HSS Snyder-Alexeyev. Hasil pengolahan data peta tutupan lahan di sub-DAS Sekayam periode 2012-2017 diperoleh pertambahan luas paling dominan adalah kelas perkebunan/kebun sebesar 8,04% serta untuk periode 2017-2022 sebesar 7,16%. Dengan koefisien pengaliran metode U.S. Forest Service tahun 2012, 2017 dan 2022 masing-masing sebesar 0,181; 0,186 dan 0,190, metode Hassing sebesar 0,244; 0,250, 0,257 dan Nilai Kodoatie Dan Syarif sebesar 0,111; 0,136, dan 0,161. Untuk periode 2017-2022 terjadi perubahan nilai C terbesar dari Kodoatie dan Syarif dengan persentase 18,83% dan ini mengakibatkan kenaikan debit sebesar 25,37%. Perubahan nilai C ini didominasi oleh pengurangan luasan kelas pertanian lahan kering campur semak dan peningkatan luasan perkebunan/kebun.
