KULYK","doi":"10.15407/scine19.05.100","DOIUrl":"https://doi.org/10.15407/scine19.05.100","url":null,"abstract":"Introduction. The paradigm of global energy development is the priority of renewable energy sources (RES), namely, wind (WPP) and solar (SPP) power plants. This process has been evolving despite the fact that these renewable energy sources, by their physical nature, are unable to provide either a stable frequency of generated energy or a guaranteed power.Problem Statement. The current threatening situation in the Integrated Power System (IPS) and in the energy market of Ukraine is caused by the hypertrophied development of SPP and WPP in the structure of Ukraine’s IPS and excessive preferences given to RES by the “green” laws.Purpose. The purpose of this research is to create a fundamentally new structure and basis of the electric-heat system operation, which unite the IPS of Ukraine and the system of centralized heat supply (CHS), by electrifying the CHS through the use of autonomous RES energy and the capacities of nuclear power plants (NPP), in order to ensure the profitability ofUkraine’s energy market and the guaranteed profitability of RES.Material and Methods. Information of NEC Ukrenergo for 2021 and periodic energy publications; system analysis for established electrical, hydraulic, and temperature modes of joint operation of IPS, CHS, WPP, and SPP for a fundamentally new organization of their interaction.Results. Management based on the “green” tariff laws has led to a significant unprofitability of the Ukraine’s energy market. The greenhouse gas emissions during the use of RES in the IPS have increased several times, as compared with such emissions, in the case of the structure of the IPS without RES. The new principle of interrelationships between IPS, CHS, WPP, and SPP ensures high manufacturability, cost-effectiveness, reliability, and environmental friendliness of each component.Conclusions. The combination of IPS and CHS structures solves several problems of the national importance: the problem of frequency and power stabilization in the IPS automatically solves; the energy market of Ukraine gets rid of USD 15 billion loss anually; it allows saving 7.28 billion m3 natural gas and reducing the carbon dioxide emissions by 98 million tons in CO2 equivalent.","PeriodicalId":21478,"journal":{"name":"Science and innovation","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135666421","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mastering the micro-plasma powder deposition (MPWD) technology for refurbishing parts of nickel-based super alloy aircraft gas turbine engine (GTE) has been remaining a relevant task of the Ukrainian air craft industry for, at least, 15 last years.Problem Statement. MPWD or subsequent heat treatment of GTE parts made of nickel-based super alloy after long-term operating hours, with high γ'-phase content, might reveal increased cracking susceptibility. The search for ways to optimize the welding deposition technology has shown the necessity to scrutinize the positive technological effect of rational choice of the quality and content of process (shielding, plasma and transporting) gases.Purpose. To study the effect of process gas content on the heat source parameters, the conditions of the formation of deposited metal and its quality.Material and Methods. Comparative study of the micro-plasma (PPS04 plasmatron, UPNS-304M welding machine) and TIG (VSVU-315 power source) arc heat parameters depending on welding current and process gas has been conducted by the conventional flow calorimetry technology. Comparative estimation of the total work piece heat input parameters has been made based on the previously developed methodology with registering the welding current parameters based on m-DAQ14 analog-to-digital converter (ADC).Results. The comparative research during MPWD of sample parts has shown that the content and quality of process gases can significantly (up to 2.5 times) affect the amount of heat transferred into the work piece and, respectively, the possibility to provide the technological strength of “base-deposited metal” welded joint.Conclusions. The industrial MPWD process optimization by the criteria of work piece heat input parameters, technological strength of “base-deposited metal” welded joint and filler powder consumption,by means of increasing argon (plasma and transporting gas) quality by other gases impurities content and switch to 90% Ar + 10% Н2 argonhydrogen mixture shielding gas has been established to be promising and expedient way to solve the problem.","PeriodicalId":21478,"journal":{"name":"Science and innovation","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135666423","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The central argument of this study is that for science to meet the challenges of globalization and justice in the 21st century, it needs to be ethically informed, and thus philosophical reflection on and in science is cardinal.Problem Statement. The study focuses on the 21st century trends in philosophical thoughts that influence scientific motivations. To this effect, the research question that the study sought to answer is, ‘How and to what extent can philosophy be valuable/influential to scientific advancements in contemporary times?’Purpose. This paper aims to demonstrate that despite some differences between science and philosophy in their origin and methodological conceptions, they do have reciprocal rudiments. The study gleaned this relationship with the view to assess the utility of their relationship in a technologically and fast-paced 21st Century. This study contributes to the literature by providing theoretical perspectives that critique conventional (Western) epistemic stances of scientific knowledge construction and highlights lessons to be learnt through a juxtaposed pool of ideas from all regions of the globe, not just from the West.Material and Methods. The methodology adopted for this study leans on a descriptive and thematic literature approach which builds on qualitative data gathered through academic journals, scholarly books, and online publications. The study review endeavors to focus on the 21st century trends in philosophical thoughts that influence scientific motivations.Results. The study notes that the relationship between science and philosophy has endured for many hundreds of years, and despite their differences which mainly lie in their scope, attitudes, methods, and peculiar challenges, both are keenly engaged in advancing increased human capacity for innovation, ingenuity, and critical thinking. The study concludes — from the prism of the future — that a critical global appraisal and continuous rigorous review of scientific and philosophical activities is essential today more than ever before, if the futures project is to contri bute effectively to the (re)construction of sustainable frameworks of scientific production that yield results in an equitable and environmentally sustainable manner.\u0000Conclusions. The study has brought to the fore, a stark reminder that neither science nor philosophy — operating singularly — offers genuine solutions on sustainable growth and development; hence stakeholders can make sense of complex phenomenon from both science and philosophy by critically reviewing their outcomes in a reciprocal manner that appreciates the advances, thegaps, and excesses from both sides. Most significantly, the study has pushed the envelope of comprehending science and philosophy beyond Western constructions that often tend to overlook, and in some cases purposely downgrade orthodox but otherwise valuable scientific insights from subaltern constellations of the global South.","PeriodicalId":21478,"journal":{"name":"Science and innovation","volume":" ","pages":""},"PeriodicalIF":0.4,"publicationDate":"2023-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44325698","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The energy sector makes the largest contribution of about 65% of the total amount to greenhouse gas (GHG) emissions in Ukraine. District heating systems (DHS) as an energy subsector are a significant source of GHG emissions as a result of the combustion of fossil carbon fuels (natural gas, coal, petroleum products, peat, etc.).Problem Statement. Due to its obvious advantages, DHS will continue to develop with the use of advanced te chnologies that allow a significant increase in the efficiency and a reduction in heat losses, and accordingly ensure the lowest cost of heat energy for consumers. However, at the moment, no forecast has been made for the dyna mics of Ukraine’s DHS fuel balance, the heat generation structure, and, accordingly, GHG emissions until 2050.Purpose. The purpose of this research is to estimate the impact of structural changes in the DHS on the greenhouse gas emissions.Material and Methods. Publications in scholarly research journals, official documents, statistical data, methods of statistical and comparative analysis have been used. Calculations have been made with the use of the Methodology of the United Nations Intergovernmental Panel on Climate Change (UN IPCC).Results. Changes in the fuel balance and the generation structure of DHS of Ukraine have been forecasted. According to the forecast results, the natural gas consumption will decrease 1.4—2 times, while that of coal will fall 1.4—5.9 times. Petroleum products will not be used in DHS after 2040, but the electricity consumption will increase 7.7—19 times. At the same time, the biomass consumption will increase 2 times, and that of solar energy will grow 77 times, as compared with 2020. In 2050, the GHG emissions from DHS will amount to 3.9—6.9 million tons of CO2-eq., depending on the DHS structural dynamics scenario.Conclusions.
