Experimental Research for Operating Thermal Electric Plant Ash in Coating Powder Production Used in the Continuous Steel Casting Lines

In this paper the authors present obtaining of a technological powder used for the continuous casting of steel. The powder is applied in the casting plant distributor to ensure thermal insulation, prevent oxidation of the steel and especially to capture the steel inclusions. The powder helps to purify the steel and thus improve its quality. The paper presents the physical and chemical characteristics of the power plant ash, which is a fine-grained waste, stored in dumps and which can be used for the production of coating powders. Several experimental recipes were made, in which the proportion of power plant ash was between 65-80%. To characterize the recipes, measurements were made to determine the humidity, volumetric mass, spread area, particle size analysis, melting temperature and chemical analysis. After analyzing the physical, chemical and thermal characteristics, pilot experimental batches were performed for testing in the steelworks. The favourable effects of the use of Cenoterm powder were highlighted by analyzing the slag samples taken from the experimental batches. These showed an increase in the MnO content of steel up to 30%, an increase in alumina, magnesium and a decrease in silica. They show that the molten powders in the formed slag are reactive and play a beneficial role in the quality of the steel. Consumption of ash-based coating powder was between 0.065 and 0.22 kg/t liquid steel

EDUCATION THROUGH INNOVATION IN THE FIELD OF METALLIC MATERIALS SCIENCE

The importance of the innovation process lies in its main functions, those of generating and leading to the conception and development of new processes and products, based on creativity. Hence the need of education for innovation. In this article we present, for a start, the main stages of an innovation process. Then, elements of innovation management, innovation strategies, innovation activities. We also present aspects regarding the financing of the innovation process and of the technology transfer. As results of the efficient application of these theoretical elements specific to an innovation process, we present the main elements of a patent (Invention Patent no. 107025/1993) of one of the authors. This patent, entitled "Burner" has gone through all stages, from conception to implementation in industry. This implementation took place in the former Special Steels Plant ok Targoviste (COST), in Electric Steel Mill no. 1 (OE1), with a good technological and economic efficienc

Legal-Ethical Challenges and Technological Solutions to e-Health Data Consent in the EU

e-Health data is sensitive and consenting to the collection, processing, and sharing involves compliance with legal requirements, ethical standards, and appropriate digital tools. We explore two legal-ethical challenges: 1) What are the scope and requirements of digital health data consent? 2) What are the legal-ethical reasons for obtaining consent beyond the GDPR’s legal basis, and how might such consent be obtained? We then propose human-centered solutions to help navigate standards of ethical and legal consent across the EU, purposefully addressing those use cases to compensate for human difficulties in managing consent without clear guidelines. These solutions – including ISO standards, ontologies, consent mechanisms, value-centered privacy assistants, and layered dynamic consent platforms – complement and aid humans to help uphold ethical and rigorous consent

Testing the Catalysts of the Romanian Creative Economy—A Panel Data Analysis Approach

There have been several decades since the creative and cultural economy (CCE) was praised for its contributions to long-term socio-economic development and also for its sustainable approach concerning the main production factors involved by the creative industries—human intellect and talent—and cultural ones, and now, more than ever, the creative sector could be perceived as vital in facing and recovering from the several crises of recent years. In order to determine the “recipe” of a flourishing local CCE, our research continues analysing seven Romanian cities, by assessing several influential factors considered as catalysts of the CCE, such as: student populations, young populations, and local public expenditure on culture during 2008–2019 for the selected creative cities. In this paper, we will determine the connection between these catalysts of the local CCEs’ development as independent variables, and two economic dimensions, the number of employees and turnover, as the dependent variables. The determination of this correlation started by using the observation method and the method of multiple regression, but further investigation was needed, so the present paper deepens the research by approaching the panel data method. Our results prove an existing correlation between the analysed variables, some of them influencing positively, and others negatively
