Abstract

The main reason behind the development of the International Safety Management Code was a series of tragic maritime accidents at the end of the twentieth century caused by human error. The ISM Code has introduced a brand new instrument, the safety management system (SMS), to the set of already existing legal devices, established to ensure safety during ship operation. Properly applied and implemented within the shipping company, SMS can be an advantage that will not only result in a measurable increase in the level of safety, but will also result in cost optimization and an increase in the company’s reputation. However, if an SMS is conceived without commitment and conviction on the part of the management, it will be only an empty and façade, bureaucratic procedure that will not only fail its purpose, but will also only be an additional burden for all staff. The following article will present the characteristics of SMS and its impact both on the broadly understood safety in the shipping company, and including vessels in its fleet, moreover the requirement of the efficiency of SMS procedures specified in shipboard manual for each vessel will be emphasized, which is the need to create a new safety culture.

Abstract

Stanisław Lem is considered the most outstanding representative of Polish and one of the most eminent representatives of world science-fiction literature, as well as a futurologist and—at least by some—a philosopher who, in the form of novels and short stories written in the convention of science fiction and the so-called discursive prose, touched upon important philosophical problems concerning the place of man in the Universe, the effects of technological and civilisational progress and the issue of the limits of cognition. The article reconstructs and analyses the main philosophical problems presented in the work Filozoficzny Lem. Wybór tekstów Stanisława Lema i opracowania [ The Philosophical Lem. A Selection of Texts by Stanisław Lem and Studies] edited by Filip Kobiela and Jakub Gomułka.

Abstract

In less than a decade, the photovoltaic sector has transformed into a global business. The dynamics of its development vary depending on the country. According to estimates, the value of the photovoltaic micro-installations market in Poland at the end of 2019 exceeded PLN 2.8 billion. In the first half of 2020, the PV sector recorded dynamic growth with a total capacity of the micro-installations of 2.5 GWp. Government subsidies were among the factors contributing to the expansion of the PV sector. In Poland, there are many financial ways to intensify the construction of new renewable energy source installations, among others: feed-in tariff, grants, and loans. An example of photovoltaic grant support in Poland is the “Mój Prąd” [My Electricity] program created in 2019 with a budget of PLN 1.1 billion. The interest in the “My Electricity” program in individual provinces may vary, depending on socio-economic factors, technological and environmental resources, and the level of innovation. The research motivation of this article is a comparison of provinces in Poland according to selected energy, environmental, innovation, and socio-economic indicators and to show how these factors affect individual interest in the “My Electricity” photovoltaic development program in provinces. The highest correlation is for the total installation power under the “My Electricity” program and Gross Domestic Product and Human Developed Index. The highest correlation coefficient from RIS indicators and photovoltaic data programs was achieved for “R&D expenditure in the business sector”. The population was closely correlated with the total installation power and the grant value of the “My Electricity” program.

Abstract

This paper presents results of mineralogical and chemical research connected with the polymorphic transformations of dicalcium silicates in aggregate based on open-hearth slag and also slags from the current production of EAF (electric arc furnaces), and LF (ladle furnaces). Particular attention was paid to the transformation of the polymorph β-Ca2[SiO4] into the variant γ-Ca2[SiO4], which is undesirable from the perspective of using steel slags in road construction. A full mineralogical characterization of the tested metallurgical slags enabled the verification of the effectiveness of detecting the decomposition of dicalcium silicate in observations in UV light in line with the PN-EN 1744- 1+A1:2013-05 standard. On the basis of the conducted research, it was found that in the aggregate based on open-hearth slags and in the EAF furnace slag, dicalcium silicates are mainly represented by the β-Ca2[SiO4] polymorph, accompanied by α’-Ca2[SiO4]. The slag from the LF furnace was characterized by a different composition, with a strong advantage (57%) of the α’-Ca2[SiO4] variety, with a 1% share of the β-Ca2[SiO4] and 15% of the γ-Ca2[SiO4].
It was found that the transformation of β-Ca2[SiO4] into γ-Ca2[SiO4] can take place only under certain conditions in the metallurgical process, but the process is not influenced by hyperergenic factors, as evidenced by the fact that after more than 100 years of storage of open-hearth slag, on the basis of which the aggregate was produced, it was primarily marked with all the variants of β-Ca2[SiO4], without the polymorph γ-Ca2[SiO4].
The comprehensive characterization of the slag phase composition requires use of an appropriately selected research methodology; this is of key importance prior to the secondary use of this material, especially in the presence of the γ-Ca2[SiO4] polymorph. It has been determined that the most accurate test results are obtained using the XRD technique. The method of determining the decomposition of dicalcium silicate according to the PN-EN 1744-1+A1:2013-05 standard proved to be unreliable. It seems that in the situation of using LF slag as an artificial aggregate, taking the test results according to the method described in the PN-EN 1744-1+A1:2013-05 standard as being decisive is very risky, especially on a large scale (e.g. in communication construction).

Abstract

Renewable energy from solar power plants is becoming more and more popular due to the depletion of raw materials and reduction of dependence on oil and gas and is also harmless to the natural environment. The management and rational use of land resources is currently a pressing problem in the world, including in Ukraine. One of the solutions is the development of technologies for the use of these areas and the establishment of environmentally friendly technologies for reducing air pollution, namely electricity facilities – solar power plants based on the use of photovoltaic panels. Choosing the right location for obtaining solar energy depends on many factors and constraints. Optimal location of solar farms is important to maximize the beneficial features of projects while minimizing the negative. A method of finding places in the vicinity of large cities that could be suitable for installing power plants was developed. The proposed method uses an analytical hierarchical process, analytical network process, Boolean logic and weighted linear combination. It has been implemented in the QGIS program. The method was successfully used for the city of Zaporizhia, but it can be directly implemented in any other region. That is why the presented works constitute a scheme that can be easily used to estimate large areas in order to optimally choose a place for a solar park in the vicinity of large cities. Such a model can be very useful for investors to find potential locations for solar energy before conducting detailed field research.

Abstract

The article applies postcolonial approaches to economic discourses in regard to Habsburg Galicia at the turn from the 18th to the 19th century, focusing on the reform discourses of the state bureaucracy, the Galician landlords and the Polish national movement with regard to serfdom and agrarian reform. Making use of Said’s concept of “orientalism”, the article’s main section is dedicated to the analysis of how the definition and construction of peasants as social actors influenced reforms of serfdom until it was finally abolished in course of the revolution of 1848. Here, several different simultaneous narratives, as well as varying positions in the course of time can be observed, where cultural differences were overlapping with social cleavages. Thus, a polycentric, but not polyvalent approach of power and rule could help deconstructing or at least questioning binary dichotomies, in the way that hegemony is always dependent on a complex web of political, social and economic relations in a spatial context.

Abstract

The paper presents data on the total phenolic and flavonoid content in Deschampsia antarctica È. Desv. plants collected from natural habitats, plants cultured in vitro, regenerated plants, and plants cultivated in a growth chamber. It was found that the shoots (aerial parts) had higher phenolic and flavonoid contents compared to the roots. The largest amount of these substances was found in wild plants from Great Yalour Island. The content of phenolics and flavonoids in plants cultured in vitro was generally comparable to that in plants collected from natural habitats except for some clones. HPLC analysis revealed five main metabolites present in similar ratios in the studied samples of wild and in vitro plants. Minor substances varied slightly in different extracts, however their presence did not depend on plant growth conditions. No significant qualitative differences in HPLC profiles were found between the wild and in vitro plants. The studied samples did not contain quercetin, kaempferol and luteolin, whereas orientin was found in all studied samples of D. antarctica.
