    In this work, tetrahedrally modified MnMe0.1Co1.9O4 (Me = Zn, Mg, Li) spinels were prepared via the sol–gel synthesis method with subsequent ball-milling fragmentation. The prepared samples were evaluated as glucose–sensing catalyst. The reference MnCo2O4 spinel exhibited a sensitivity of 49 µA mM−1 cm−2 and a nonlinearity error of 5.2% in the response range from 0.02 to 1 mM. The partial substitution of cobalt in the reference spinel enhanced the glucose–sensing abilities, and the sample with Li was found to be the most active catalyst, exhibiting a sensitivity of 73.1 µA mM−1 cm−2. Finally, the proposed material was tested for selectivity in the presence of interfering sucrose.

    The anticancer properties of quinolones is a topic of interest among researchers in the scientific world. Because these compounds do not cause side effects, unlike the commonly used cytostatics, they are considered a promising source of new anticancer drugs. In this work, we designed a brief synthetic pathway and obtained a series of novel 8-phenyltetrahydroquinolinone derivatives functionalized with benzyl-type moieties at position 3. The compounds were synthesized via classical reactions such as nucleophilic substitution, solvent lysis, and condensation. Biological evaluation revealed that 3-(1-naphthylmethyl)-4-phenyl-5,6,7,8-tetrahydro-1H-quinolin-2-one (4a) exhibited potent cytotoxicity toward colon (HTC-116) and lung (A549) cancer cell lines. Analysis of the mechanism of action of compounds showed that compound 4a induced cell cycle arrest at the G2/ M phase, leading to apoptotic cell death via intrinsic and extrinsic pathways. Taken together, the findings of the study suggest that tetrahydroquinolinone derivatives bearing a carbonyl group at position 2 could be potential lead compounds to develop anticancer agents for the treatment of lung cancers

  • The Application of a Multi-Criteria Decision-Making for Indication of Directions of the Development of Renewable Energy Sources in the Context of Energy Policy

    2022 Full text ENERGIES

    This paper presents the application of multi-criteria decision-making (MCDM) for evaluating what technologies using renewable energy sources (RES) for electricity production have the chance to develop in Poland under the current socio-economic conditions. First, the Analytical Hierarchy Process (AHP) method was used to determine the weights of the optimization criteria. Five main criteria and 30 sub-criteria were identified. Next, the authors modified numerical taxonomy (NT) to rank eight RES technologies (such as onshore and offshore wind farms, photovoltaics, or biogas plants). The results show that offshore wind farms are the RES technology with the greatest development opportunities in Poland. The following three technologies: distributed photovoltaic energy, biogas plants, and biomass power plants, respectively, received a similar rating in the ranking. Hydropower and geothermal were the lowest-ranked technologies. The ranking, which is the result of multi-criteria analysis, in several respects, is significantly different from the directions of activities indicated in the state energy policy.

  • The Application of Satellite Image Analysis in Oil Spill Detection

    2022 Full text Applied Sciences-Basel

    In recent years, there has been an increasing use of satellite sensors to detect and track oil spills. The satellite bands, namely visible, short, medium infrared, and microwave radar bands, are used for this purpose. The use of satellite images is extremely valuable for oil spill analysis. With satellite images, we can identify the source of leakage and assess the extent of potential damage. However, it is not yet clear how to approach a specific leakage case methodologically. The aim of this study is the remote sensing analysis of environmental changes with the development of oil spill detection processing methods. Innovative elements of the work, in addition to methodological proposals, include the long‐term analysis of surface water changes. This is very important because oil is very likely to enter the soil when water levels change. The classification result was satisfactory and accurate by 85%. The study was carried out using images from Landsat 5, Landsat 7, Landsat 8, Sentinel‐1, and Sentinel‐2 satellites. The results of the classification of the oil stains in active and passive technologies differ. This difference affects the methodology for selecting processing methods in similar fields. In the case of this article, the oil spill that occurred on 29 May 2020 in Norilsk was investigated and compared with data from other years to determine the extent of biodegradation. Due to the tank failure that occurred at the Nornickel power plant on that day, a large amount of crude oil leaked into the environment, contaminating the waters and soil of local areas. Research shows that oil spills may be caused by human error or may be the effect of climate change, particularly global warming.

  • The Application of the Thermal Stabilization Prompted by the Ice Cover Expansion Considering the Energy Production Optimization in the Dam-Reservoir Coupled Systems on the Vistula River

    2022 Full text ENERGIES

    In this study, the thermal stabilization of a water resource together with an energy production optimization in the power plant of the dam–reservoir coupled system is conducted. This coupled dam system is designed to consist of a primary (Włocławek) and secondary (Siarzewo) dam due to the erosion control aspect. The other beneficial aspect of this coupled dam design is to have an additional power plant, with the aim of achieving more efficient renewable energy production. One of the factors to be included in the conditions influencing the energy production is the ice formation in the reservoir and tailwater due to the hydrodynamic and meteorological conditions of the site location. Frazil formation and jam may reduce the power plant efficiency. The concept of thermal stabilization, based on the previous studies, refers to providing the ice cover in the reservoir section of a dam to isolate the water from thermal condition. In this research, the ice cover expansion is triggered by the discharge reduction over a specific time and the entire study site. The optimized discharge for stimulating the ice cover through the night was found based on the results, leading to the desired thermal stabilization. This power loss emerged by reduced water withdrawal in the specific time during the day (nighttime), and will be remedied by the more suitable hydrodynamic condition over winter.

    The issues of the article are associated with the development of the renewable energy source (RES) sector in the world and in Poland. The subject is undoubtedly connected with the problem of the energy transformation taking place in most countries nowadays. Energy transformation processes are mainly associated with an increase in the share of energy production from RES and increased awareness of energy use by end consumers. This means that the systematic development of the RES sector is a necessary condition for linking the effective course of energy transition processes with simultaneous socio-economic development. The main objective of this study is to present the status of the RES sector in Poland against the background of worldwide development tendencies. The implementation of the objective made it possible to indicate key trends in the production and use of energy from individual RES and to assess to what extent Poland follows global trends. Poland is one of the European countries where hard coal and lignite constitute the main source of energy. On the other hand Poland, as a Member State of the EU, is obliged to implement the energy strategy within the framework of the European Green Deal, where all Member States are to become climate neutral.

  • The atlas of inequality aversion: theory and empirical evidence on 55 countries from the Luxembourg Income Study database
    • Stanisław Kot
    • Piotr Paradowski
    2022 Full text EQUILIBRIUM Quarterly Journal of Economics and Economic Policy

    Research background: In the distributive analysis, the constant relative inequality aversion utility function is a standard tool for ethical judgements of income distributions. The sole parameter ε of this function expresses a society’s aversion to inequality. However, the profession has not committed to the range of ε. When assessing inequality and other welfare characteristics, analysts assume an arbitrary level of ε, common to all countries and years. This assumption seems unjustified. Purpose of the article: This paper aims to estimate the parameter ε for each country and year individually using datasets from the Luxembourg Income Study Database in all available years, which dates back to the 1970s. Methods: We utilise the method of estimating ε, which assumes the generalised beta of the second kind distribution of incomes. The estimator of ε is derived from the mathematical condition of the existence of the social welfare function. Findings & value added: We have elaborated an ‘atlas’ of 388 estimates of ε for 55 countries across time. Inequality aversion is country-year specific, with a minimum of 0.97 and a maximum of 3.8. Ninety per cent of all estimates are less than 2.5. Inequality aversion is negatively correlated with income inequality, but it is independent of economic development. Thus inequality aversion appears as an additional dimension of the classical inequality-development relationship. This article contributes to solving a fundamental problem of Welfare Economics: directly measuring the social utility of income (welfare) function. The estimates of ε for 55 countries imply a complete knowledge of these countries' constant relative inequality aversion utility functions.

    Open Research Data (ORD) is one of the emerging trends for researchers across the globe. However, it has to be stressed that the level of implementation and awareness of ORD varies between countries. Many initiatives have been created in Polish scientific institutions to support the process of opening publications. These are mainly Open Access (OA) repositories, implementing the so-called green road of OA. However, only a few universities in Poland offer their researchers essential tools and substantive support for opening research data. The Gdańsk University of Technology has created several tools and services supporting the open sharing of scientific research results, including scientific publications and research data. The Bridge of Data project was established to support researchers in their activities regarding different Open Science layers. The project is unique in this part of Central and Eastern Europe. It involves three Pomeranian universities: Gdańsk University of Technology (leader), the University of Gdańsk, and the Medical University of Gdańsk. The chapter aims to present the Bridge of Data project’s assumptions and results, which provides both an open data repository and a range of additional services for researchers who want to share their research results openly. Project assumptions will be presented along with their genesis and the result of their implementation. The technical aspects of creating IT tools (data repository, data analysis on a supercomputer, platforms for scientific journals and conferences) will be highlighted. The Open Science Competence Center, its tasks and the manner of their implementation will also be discussed. An important aspect discussed in the chapter will also be the cooperation of various university teams to create tailored tools and services. These groups include librarians who design technical solutions and support services, IT specialists building IT platforms and tools, and researchers representing various scientific disciplines. The last group enters data into the repository and helps adapt the functionality of the tools to users’ requirements. Based on an analysis of the functionality of the IT tools and based on reports on the activities of the Competence Center, a solution model will be drawn up that can be compared with other implementation cases of similar tools and services.

    2022 Full text STUDIA EUROPEJSKIE

    The formation of a favourable business environment and the intensification of entrepreneurial activity on this basis is one of the priorities of economic policy of governments around the world. The aim of this article is to conduct a comparative analysis of some of the characteristics of the business environment of Georgia and Ukraine. The theoretical basis of the study is the understanding of the business environment as a necessary prerequisite for the implementation of entrepreneurial initiatives in a particular country. In the process of our research, the following methods were used: comparative analysis, generalisation, content analysis, correlation, and regression analysis. The authors studied the business environment of Georgia and Ukraine on the basis of an analysis of the following components; that of general economic, political and legal, financial, and fiscal. The results of the study show that Georgia’s business environment is more favourable than Ukraine’s. It is noted that between 2011–2020, Georgia made significant progress in the fight against corruption, in simplifying the procedures for starting a business, and bettering access to finance. Both countries are reforming their tax systems towards liberalisation and democratisation, and they declare the functioning of special tax regimes. According to the Paying Taxes indicator, which is calculated within the Doing Business rating, Georgia improved its result from 61st position in the ranking in 2011 to 14th position in 2020, while Ukraine improved its result from 181st place in 2011 to 65th place in 2020. It is indicated that between 2011–2020, Ukraine showed significant positive dynamics in inflation targeting. The authors note that the weakest elements of the business environment in Ukraine are its efforts to ensure the independence of the judiciary and the fi ght against corruption. In conclusion, the authors note that the policy of the governments of Georgia and Ukraine should be aimed at the further democratisation of relations with businesses in order to increase the level of a favourable business environment.

  • The Changing Nature of In‐Between Spaces in the Transformation Process of Cities

    2022 Full text Urban Planning

    In the in‐between spaces of cities, there are many problems of various nature and scale: functional, spatial, economic, environmental, visual, and social. There are also some hidden potentials that can be activated. The aim of the article is to explore the possibilities of solving existing problems and to show the possibilities of using the potentials of in‐between spaces with regard to the changing nature of a city. The article, of a discursive character, aims to answer the questions of whether connecting a city with public spaces can be a catalyst of changes, and what tools should be used to facilitate the flux of material factors (like goods or natural resources) and immaterial matter (e.g., ideas or cultural patterns). The new approach is based on the assumption that this would be most effective when using landscape architecture, green/blue infrastructure, artistic strategies, and universal design in public spaces. The expected result of the research is to show the purposefulness and possibilities in creating attractive and safe public areas of in‐between spaces as an on‐going micro‐ or macro‐process of urban change on a wider scale. It was recognised that integrated actions combining the humanistic, eco‐ logical, and technical approaches could bring significant benefits to society, preventing existing problems, not only spatial and visual (changing the city directly), but above all social and environmental, having an impact on the functioning of the city from a much longer perspective. The results of the research show how the transformation process of public spaces may change the nature of the cities, improve the compactness of existing cities, and increase the quality of life. Selected case studies are presented to show the scale, scope, and benefits of possible actions.

  • The Chernobyl effect

    2022

    The 1986 Chernobyl catastrophe was not only a human and ecological disaster, but also a political-ideological one, severely discrediting Soviet governance and galvanizing dissidents in the Eastern Bloc. In the case of Poland, what began as isolated protests against the Soviet nuclear site grew to encompass domestic nuclear projects in general, and in the process spread across the country and attracted new segments of society. This innovative study, combining scholarly analysis with oral histories and other accounts from participants, traces the growth and development of the Polish anti-nuclear movement, showing how it exemplified the broader generational and cultural changes in the nation’s opposition movements during the waning days of the state socialist era.

  • The community involvement of courts: an action research study in the context of the Polish justice system

    2022 Full text Social Responsibility Journal

    Purpose – As a rule, common courts are hermetic organizations, separated from their stakeholders by procedures based on legal provisions. For these reasons, they are often perceived as unreliable and non-transparent, and as such, they do not inspire trust among stakeholders. The authors posit that the court’s community involvement may lead to the increased accountability and legitimacy of courts, which should in turn result in jurisprudence benefits. This paper discusses the concept of community involvement of courts, demonstrates how this ideamay be implemented and explains its benefits for courts. Design/methodology/approach – The results of an action research study undertaken between June 2013 and March 2018 at the Regional Court in Gdansk (Poland) are discussed. Findings – The results highlight factors underlying the implementation of the idea of community involvement, as well as the areas in which courts take these actions, and explain how it influences their accountability and legitimacy. This research describes the interests of different stakeholders and proposes a range of actions that may be taken by courts while cooperating with stakeholders to achieve the aims of community involvement. It also proposes a set of steps that enable courts to implement the idea of community involvement. Originality/value – This paper develops the idea of the community involvement of courts, which may be used as an operating rule for public institutions to increase their legitimacy and accountability and explain its introduction in the context of courts. It offers a universal framework for the community involvement of courts that can be used in the context of any court in both the continental and Anglo-Saxon systems.

    Chemopreventive properties of Brassica vegetables are attributed mainly to their characteristic compounds—glucosinolates (GLs) and their main hydrolysis products—isothiocyanates (ITCs) and indoles. In this study, we compared antiproliferative activity (MTT test in HT29 cells) and genotoxic effects (comet assay in HT29 cells and restriction analysis in a cell-free system) of three GLs (sinigrin (SIN), glucotropaeolin (GTL), and glucobrassicin (GLB)) with that of their major degradation products. Intact GLs did not exhibit cytotoxic activity, possibly due to their limited bioavailability. However, in the presence of myrosinase (MYR), GLs gained the ability to inhibit HT29 cells’ growth. The addition of MYR caused the hydrolysis of GLs to the corresponding ITCs or indoles, i.e. compounds that show stronger biological activity than parent GLs. Pure ITC/indole solutions showed the strongest antiproliferative activity. Based on the results of restriction analysis, it was found that GLs to a greater extent than ITCs caused DNA modification in a cell-free system. In the case of GLs, metabolic activation by the S9 fraction increased this effect, and at the same time changed the preferential binding site from the area of base pairs AT to GC base pairs. Of all compounds tested, only benzyl ITC caused DNA damage detectable in the comet assay, but it required relatively high concentrations.

  • The concept of a new two-stage fuse for high power pulse forming
    • Mikołaj Nowak
    2022 Full text Scientific Reports

    This manuscript introduces the concept, physical operating principle and studies on a new and unique two stage forming fuse (TSFF) with interstage spark gap commutation and presents its application for forming high power pulses of extreme parameters. The paper classifies TSFF performance and compares it with conventional single-stage forming fuses. The conclusions are supported by analytical and experimental studies in laboratory conditions. The design of the TSFF prototype as well as the applied measurement methods and test stands are also presented. The developed technology of the TSFF enables the achievement of unprecedented parameters of high-power pulses with overvoltages reaching 800 kV and pulse power of tens of GW in a very compact design. The unique properties of the TSFF enable its efficient integration with a wide range of energy sources, even with very limited current rising steepness or limited output voltage, which has not been possible so far with conventional single-stage forming fuses. The proposed system can be easily scaled, while ensuring much greater flexibility of applications.

  • The Concept of Using the Decision-Robustness Function in Integrated Navigation Systems

    2022 Full text SENSORS

    The diversity and non-uniformity of the positioning systems available in maritime navigation systems often impede the watchkeeping officer in the selection of the appropriate positioning system, in particular, in restricted basins. Thus, it is necessary to introduce a mathematical apparatus to suggest, in an automated manner, which of the available systems should be used at the given moment of a sea trip. Proper selection of the positioning system is particularly important in integrated navigation systems, in which the excess of navigation information may impede the final determinations. In this article, the authors propose the use of the decision-robustness function to assist in the process of selecting the appropriate positioning system and reduce the impact of navigation observations encumbered with large errors in self-positioning accuracy. The authors present a mathematical apparatus describing the decision function (a priori object), with the determination of decision-assistance criteria, and the robustness function (a posteriori object), with different types of attenuation function. In addition, the authors present a computer application integrating both objects in the decision-robustness function. The study was concluded by a test showing the practical application of the decision-robustness function proposed in the title.

    The purpose of this study was to evaluate the content of biogenic amines (BAs) in wines using dispersive liquid–liquid microextraction–gas chromatography–mass spectrometry (DLLME-GC–MS). An additional objective was to assess the correlations between selected parameters characterizing the samples such as the content of BAs, sugars, and organic acids, pH, and total acidity. Wines produced from the same grape variety in which alcoholic fermentation (AF) was carried out by different yeast strains and in which malolactic fermentation (MLF) was spontaneous, differed in the content of biogenic amines. The concentrations of putrescine, cadaverine and tryptamine were higher in the Rondo wines (237–405, 34.04–61.11, <LOD-12.456 µg/L, respectively) and Zweigelt wines (416–489, 72.67–88.43, <LOD-13.083 µg/L, respectively) subjected to spontaneous MLF than in the wines subjected to induced MLF. Chemometric analysis allowed us to determine correlations between selected wine parameters. The wine samples are well separated into two patterns depending on the grape variety. Despite the fact that information on BAs is not included in databases of wine composition, information on their concentration as well as knowledge of existing correlations between BAs and other wine parameters is crucial and may be useful for the food industry, health professionals and consumers.

    The thermal pyrolysis of agriculture biomass has been studied in a fixed-bed reactor, wherethe pyrolysis was conducted at a steady temperature of 800◦C. This work analyses the pyrolysisproducts of six agricultural wastes: pistachio husks, walnut husks, sunflower hulls, buckwheat husks,corncobs and coconut shells. The conducted research compared examples of large waste biomassstreams from different parts of the world as a potential source of renewable energy. Additionally, thekinetics of the reaction with the activation energy were analyzed and calculated for all raw materialsin pyrolysis process. Biochars are characterised by higher combustion heat in comparison to the rawmaterial samples. The average value of the heat of combustion increased due to pyrolysis processfrom 10 MJ/kg, with minimal value of 2.7 MJ/kg (corncob) and maximum of 13.0 MJ/kg for coconut,which is also characterised by the maximal absolute combustion heating value (32.3 MJ/kg). Theincrease in calorific values varied from 15% to 172% (with 54% reference for wood chips), whichindicates that charring is an effective method for increasing the energy concentration. The obtainedbiochar were compared with wood chips, which are widely used solid fuel of organic origin. Thestudied biomass-derived fuels are characterised by lower ash contribution than wood. An analogousobservation was made for the obtained biochars, whose ash contribution was lower than for thechips in terms of both unit-mass and unit-combustion-heat. The main advantage of this method isthe production of solid fuel from biomass, which increases the calorific value and bulk density ofbiochar in comparison to raw material.
