Abstract

The purpose of this research work is to study the issues of the protection of 6–10 kV lines and access ways overvoltage in the electrical networks of modern enterprises of high-energy intensity, as well as the search for real technical opportunities to improve the protection of power lines directly in conditions of their operation. The methodology of this scientific research is based on a combination of methods of system analysis of the principles of the functioning of electric networks of energy-intensive enterprises with an analytical study of the fundamental aspects of ensuring the protection of 6 to 10 kV lines and access ways from overvoltage. The results of the conducted scientific research indicate the relevance of the issues of ensuring the protection of lines and electrical networks of energy-intensive enterprises from overvoltage and the need to develop special technical devices to ensure the proper level of such protection in real conditions. The results and conclusions of this research work are of significant importance for developers and designers of electric networks of enterprises with increased energy capacity, as well as for employees of various power supply systems who, by their occupation, face the tasks of servicing electric networks, which include lines and access ways with specified operating voltage parameters and ensuring the proper level of safety and practical use of these electric networks of energy-intensive enterprises.

Abstract

Ore and non-ore mineralization in cracks filled with hydrocarbons in the dark grey Upper-Devonian limestone has been found in the Józefka quarry of Upper Devonian limestone and dolomite near the Górno village near Kielce at Holy Cross Mts. Poland. Hydrocarbons in the liquid form and iron and copper sulphides appears hear in the fault zone as joints filling. The wall rocks are impregnated by hydrocarbons giving them black color. Hydrocarbon impregnations appears also following the bedding planes The coexistence of ore mineralization and hydrocarbon suggests their common origin and migration from deep-seated sources, that may be the Silurian Ordovician or Lower to Middle Devonian black shales. The metallic-hydrocarbon compounds were suggested as metals carrier.

Abstract

The main theme of this paper is to study two important aspects of precise geoid determination using Helrnerts second method of condensation. This work illustrates via numerical investigations the importance of using actual density information of topographical bulk and the effects that different gravimetric reductions have on gravity interpolation in Helmert geoid computational process, in addition to the commonly used Bouguer scheme. A rugged area in the Canadian Rockies bounded by latitude between 49°N and 54°N and longitude between 236°E and 246°E is selected to carry out numerical investigations. The lateral density information is used in all steps of the Helmert geoid computational process. The Bouguer and residual terrain modelling (RTM) topographic reductions, the Rudzki inversion scheme, and the topographic-isostatic reductions of Pratt-Hayford (PH) and Airy-Heiskanen (AH) are used for gravity interpolation. Results show that the density information should be applied in all steps of the Helmert geoid computational process and that the topographic-isostatic gravimetric reduction schemes like the PH or AH models or the RTM reduction, should be applied for smooth gravity interpolation instead of the commonly used Bouguer reduction scheme for precise Helmert geoid determination.

Abstract

This study aimed to compare measures of religiosity and spirituality in the experience of positive and negative emotions. For this purpose, a measure of non-spiritual religiosity (Religious Sense Scale) was developed. Method: The study has been conducted on a sample of 279 participants aged between 19 and 69 (M=24.42, SD=9.463) who completed a questionnaire that included the Religious Sense Scale, the Portuguese version of the Spiritual Well-being Questionnaire and the abridged Portuguese version of the Positive and Negative Affect Schedule. Findings: The was found to have excellent metrical properties for the measurement of religiosity or “religious sense”. Religious individuals differ from spiritual ones in the experience of emotions: spirituality tends to a greater experience of positive affect and religiosity to negative affect.

Abstract

Mimicry has been proven to be responsible for many social consequences linked to social bonding: improved trust, liking, and rapport. This accumulating empirical evidence has mostly been based on experimental designs focused on comparisons between two conditions: an experimental condition involving mimicking behavior versus a control condition in which any movement or direct verbal reaction is withdrawn. Thus, it is unclear whether the observed differences stem from a potential increase in liking, trust, or rapport in the mimicry condition or a decrease thereof when naturally occurring gestures are not present during the interaction. To address this potential confound, we included an additional control condition involving responsiveness (but not mimicry) aimed at increasing both internal and external validity. We found significant differences between the mimicry condition and both control conditions, thereby lending support to the original mimicry-as-a-social-glue hypothesis.

Abstract

In the paper positive fractional continuous-time linear systems are considered. Positive fractional systems without delays and positive fractional systems with a single delay in control are studied. New criteria for approximate and exact controllability of systems without delays as well as a relative controllability criterion of systems with delay are established and proved. Numerical examples are presented for different controllability criteria. A practical application is proposed.

Abstract

In order to ensure the territorial development of land use in the region, there is a need to change the trajectory of spatial and urban planning factors. The ways for implementation of the proposed system measures are defined in the article. For investment and environmental indicators, the integrated indicator of territorial development of land use in the region, depending on their change, is predicted. The article presents the results of forecasting the integrated indicator of land use territorial development in the region based on the growth of systemic investment factors and the results of forecasting the integrated indicator of land use territorial development based on the growth of systemic environmental factors. Practical scientific-based recommendations for ensuring the territorial development of land use in the region by applying the results of its integrated assessment and modeling are proposed. Developed recommendations made it possible to form directions and build the basis for ensuring the territorial development of land use in the region. The development of methodological recommendations for ensuring the territorial development of land use in the region is based on the results of the study of the influence of systematic spatial, urban, investment, and environmental factors on the integrated indicator of land use territorial development.

Abstract

Descriptions have been the object of attention of many philosophers. The goal of this article is to inquire into the meaning of those descriptions which, due to the peculiar character of the objects of description, have been interpreted in different ways, and to investigate in which sense one is able to speak of the existence (or non-existence) of an object of description. The various sorts of descriptions are inquired; the ques-tion which entities exist and which do not is dealt with, and, in relation to this, how ‘meaning’ is to be understood.

Abstract

Workplaces have become increasingly diverse as a result of migration and other socio-economic changes in Europe. In the light of post-2004 migration, many Polish migrants find themselves in work-places where multiculture is an everyday lived experience. By drawing on narrative interviews conducted with Polish migrant women in Manchester and Barcelona, this paper focuses on the complexities of interaction with other ethnic groups at work, demonstrating various forms of conviviality. The study reveals more and less meaningful forms of contact at work including workplace friendships, light-hearted forms of conviviality characterised by the interplay of language and humour, relations based on care and respect for difference, as well as forced encounters marked by superficial and involuntary interaction. The findings show that while workplace can be a place of meaningful interaction, it can also involve conflict and tensions. The narratives illustrate that workplace relations can be influenced by the dynamics of gender, race, ethnicity, socio-economic circumstances and immigration discourses. The paper contributes analytically and empirically to the understanding of different forms of encounters in the workplace.

Abstract

This paper analyses diaspora advocacy on behalf of Ukraine as practiced by a particular diaspora group, Ukrainian Canadians, in a period of high volatility in Ukraine: from the EuroMaidan protests to the Russian invasion of Eastern Ukraine. This article seeks to add to the debate on how conflict in the homeland affects a diaspora’s mobilisation and advocacy patterns. I argue that the Maidan and the war played an important role not only in mobilising and uniting disparate diaspora communities in Canada but also in producing new advocacy strategies and increasing the diaspora’s political visibility. The paper begins by mapping out the diaspora players engaged in pro-Ukraine advocacy in Canada. It is followed by an analysis of the diaspora’s patterns of mobilisation and a discussion of actual advocacy outcomes. The second part of the paper inves-tigates successes in the diaspora’s post-Maidan communication strategies. Evidence indicates that the dias-pora’s advocacy from Canada not only brought much-needed assistance to Ukraine but also contributed to strengthening its own image as an influential player. Finally, the paper suggests that political events in the homeland can serve as a mobilising factor but produce effective advocacy only when a diaspora has already achieved a high level of organisational capacity and created well-established channels via which to lobby for homeland interests.

Abstract

This article deals with migrants’ experiences of precarious working conditions in the cleaning and con-struction industries in the Danish labour market as seen from their perspective. The experiences are retained through biographical narrative interviews with migrant workers from Central and Eastern Europe and are used to gain an understanding of the concrete strategies they apply when coping with their short-term contracts, demanding working hours, risk of unemployment and other insecurities. Mi-grants’ experiences of precarity and insecurity in their work is confirmed, to some degree, in numerous research studies. However, the resistance and strategies expressed by the migrant workers in their nar-ratives show that they have also developed specific ways to cope with this precarity. The article con-tributes to a new understanding of migrants’ responses to precarity in which they engage their social and cultural resources to cope with the labour market conditions they face in Denmark.

Abstract

Ukraine has been going through a series of political and economic crises, notably the Euromaidan revolution and the Russian aggression and subsequent economic downturn. These events triggered fresh transnational diaspora-led activities such as the ‘London Euromaidan’ and the ‘Warsaw Euromaidan’. This paper analyses Ukrainian diaspora volunteerism in the UK and Poland and explores how the Ukrainian diaspora engages and contributes economically, socially, politically and culturally to the development of Ukraine. Drawing on fieldwork in both countries, three main findings were identified. First, due to the events in Ukraine, the Ukrainian diaspora has mobilised, grown stronger and became more united, whilst transforming from a more inward-looking to a more outward-looking community which, as a result, is now more and critically engaging with Ukrainian affairs. Second, the Ukrainian diaspora has the willingness, power and resources to contribute to the development of the home country, claiming to be recognised as an important stakeholder in the development of Ukraine. Thirdly, the Ukrainian government’s lack of recognition of the contribution of the Ukrainian diaspora is one of the most significant barriers to more comprehensive diaspora involvement in development.

Abstract

For the purpose of making of a solid body of an electric guitar the acoustic- and mechanical properties of walnut- (Juglans regia L.) and ash wood (Fraxinus excelsior L.) were researched. The acoustic properties were determined in a flexural vibration response of laboratory conditioned wood elements of 430 × 186 × 42.8 mm used for making of a solid body of an electric guitar. The velocity of shearand compression ultrasonic waves was additionally determined in parallel small oriented samples of 80 × 40 × 40 mm. The research confirmed better mechanical properties of ash wood, that is, the larger modulus of elasticity and shear modules in all anatomical directions and planes. The acoustic quality of ash wood was better only in the basic vibration mode. Walnut was, on the other hand, lighter and more homogenous and had lower acoustic- and mechanical anisotropy. Additionally, reduced damping of walnut at higher vibration modes is assumed to have a positive impact on the vibration response of future modelled and built solid bodies of electric guitars. When choosing walnut wood, better energy transfer is expected at a similar string playing frequency and a structure resonance of the electric guitar.

Abstract

Septoria melissae Desm., the most important pathogen of lemon balm (Melissa officinalis) occurs each year on plantations. The fungus may cause serious yield losses in the absence of proper plant protection. Breeding resistant or tolerant cultivars could play an important role in plant protection of medicinal plants. However, only a few descriptions of tolerant varieties of lemon balm are available. The goal of this work was to evaluate the susceptibility of three accessions of M. officinalis against the pathogen of Septoria leaf spot under field conditions at Budapest-Soroksár (Hungary) in 2017–2018. Differences in susceptibility of the accessions were observed in both years. The accession of M. officinalis subsp. altissima proved to be the least susceptible to Septoria infection. The frequency of the infected leaves was only 5.1 and 28.1% in 2017 and 2018, respectively. However, the cultivar M. officinalis subsp. officinalis ‘Lorelei’ turned out to be the most susceptible to the pathogen with an average infection level of 26.1 and 66.6%, 1.3–6.1 times higher than that of the other accessions in each year, respectively. Development of disease tolerant M. officinalis cultivars may be an effective tool in the plant protection of lemon balm.

Abstract

The paper presents results obtained during experiments with constructed wetlands that were built and monitored on the site of a municipal landfill in Southern Poland. The wetland was filled with gravel and rock in which reeds, cattails and willow were planted. A control plot without vegetation was also constructed. Each wetland was loaded with a portion of the leachate generated by the landfill. Measurements of the leachate quality showed very high concentrations of several pollutants. Particularly high concentrations of BOD, COD, nitrogen, and heavy metals were measured. High pollutant levels were probably responsible for the demise of the willows, which were dead within several months of planting. The efficiency of pollution removal with detention time up to 24 h ranged from O to 87% based on decreasing concentration of selected parameters. However, the removal efficiency of the control plot was typically only several percent lower than the removal efficiencies of the plots with vegetation.

Abstract

The aim of this work is purification of contaminated soil from manufactured gas plants MGP, which arc not used. Prepared chromatographic methodologies, which allow qualitative identification and quantitative determination of individual aliphatic and aromatic (TAH, PAH) hydrocarbons in the soil from the selected MGP, arc presented. The results of the research on remediation of the soil polluted with petroleum hydrocarbons (TAH, PAHs) in semi-field conditions arc discussed. Application of basic biorcmcdiation and bioaugmcntation with indigenous microorganisms, enriched with PAH biodegradable fungi, resulted in reduction in amount of 5- and 6-polycyclic aromatic hydrocarbons. The research enables control of remediation progress, selection of optimal doses of biogenie compounds and determines the time of the process. The entire cycle of soil remediation was monitored with the use of gas chromatography (GC). Estimation ofbiodcgradation degree of individual aliphatic hydrocarbons (alkancs) was based on changes in their concentration in the soil and determined by biodegradation indicators: C,/pristanc and C,/phytanc ratios. Attention was paid particularly to biodcgradation of polycyclic aromatic hydrocarbons (PAH), which were observed in substantial concentrations in the polluted soil. The elaborated chromatographic methodology of PAH determination in the soil enabled estimation of a biodcgradation rate referring to individual compounds. Moreover, attempts to create a TAH biodcgradation model with the use of C30-l 7a(H),2 l l3(H)-hopanc were undertaken.

Geographical names reflect a complex intermingling of language, culture, history, and economics. The disappearance of names for small physiographical features, known only to small local communities, is driven in part by changes in economic activity – a process that may be observed in the micro-toponymy of the Hutsul region in Ukraine
