This article aims to reconstruct Max Scheler’s conception of three types of knowledge, outlined in his late work Philosophical Perspectives (1928). Scheler distinguished three kinds of knowledge: empirical, used to exercise control over nature, eidetic (essential) and metaphysical. I review the epistemological criteria that underlie this distinction, and its functionalistic assumptions. In the article’s polemic part I accuse Scheler of a) crypto-dualism in his theory of knowledge, which draws insufficient distinctions between metaphysical and eidetic knowledge; b) totally omitting the status of the humanities in his classification of knowledge types; c) consistently developing a philosophy of knowledge without resort to the research tools offered by the philosophy of science, which takes such analyses out of their social and historical context (i.e., how knowledge is created in today’s scientific communities).

The aim of this article is to present the author’s opinion about possible underwater natural gas pipeline monitoring using Polish Navy resources. Due to the bathymetrical characteristics of the pipeline equatorials the high efficiency and safe for the deck operators systems are expected to support the bottom survey and gas line monitoring. Time and engaged resources reduction are crucial factors in this kind of mission together with high probability of possible dangerous objects detection. The paper describes main threats for the underwater transportation line as a state energetic independence vital object (supplies diversification). An example of a threat caused by lost unmanned platform technologies near Nord Stream was presented and analyzed as well. The rapid development of unmanned maritime technologies (aerial, surface and subsurface) observed in the last decade creates new possibilities in maritime security/surveillance applications. The Polish mine counter measures assets which were equipped with sophisticated AUV’s as a part of the Polish Navy modernization process (new minehunters Kormoran IInd class deployable). The presented autonomous underwater vehicles (AUV) are equipped with advanced sonars and create new possibilities in the issue of effective threats detection/classification/ identification and neutralization. The main advantages of such solutions were pointed in the article with the crucial one based on time reduction as well as human – deck operators threats constraints. The first successes in the operational use of unmanned systems were reached during the military exercises (historical ordnance disposal) conducted on historical mine laying areas. This creates good possibilities to train the unmanned system operators in live objects activity which improves skills and knowledge. Moreover, the double use applications of unmanned technologies both in defense and maritime security has been observed.

Port cities are having diff erent spatial structure than those located inlands. As a result of their seaside location, they face specifi c administrative and functional problems on a daily basis. In the economic and settlement structure of the country, they usually play the role of a “gate” through which streams of cargo are distributed further over the whole hinterland. It is the transport and logistics function of port cities, as well as the water bodies located in their area, that determine their spatial character to the greatest extent. The confi guration of the two above- mentioned factors, together with other development conditions, determines the model of spatial changes taking place in port cities. Additionally, evolving shipping technologies aff ect the contemporary development of the ports’ and port cities’ spatial structure.

A significant part of hard coal production (15–19% in the years 2010–2017, i.e. 1.0–1.3 billion

tons per year) is traded on the international market. The majority of coal trade takes place by sea,

accounting for 91–94% of the total coal trade. The article discusses the share of coal in international

seaborne trade and the largest coal ports. Coal is one the five major bulk commodities (in addition

to iron ore, grain, bauxite, alumina, and phosphate rock). In the years 2010–2016, the share of coal

in international seaborne trade and major bulk commodities was 36–41% and 11–12%, respectively.

Based on the analysis of coal throughput in different ports worldwide, the ports with the

largest throughput include the ports of Qinhuangdao (China), Newcastle (Australia), and Richards

Bay (South Africa). For 2013–2017, their throughput amounted to a total of 411–476 million tons

of coal. The largest coal exporting countries were: Australia, Indonesia, Russia, Colombia, South

Africa, and the US (a total of 85% share in global coal exports), while the largest importers are

Asian countries: China, India, Japan, South Korea and Taiwan (a 64% share in global imports). In

Europe, Germany is the largest importer of coal (54 million tons imported in 2016). The article also

discusses the freight costs and the bulk carrier fleet. Taking the price of coal at the recipient’s (i.e.

at the importer’s port) into account, the share of freight costs in the CIF price of steam coal (the

price of a good delivered at the frontier of the importing country) was at the level of 10–14%. In

the years 2010–2016, the share of bulk carriers in the world fleet was in the range of 11–15%. In

terms of tonnage, bulk carriers accounted for 31–35% of the total tonnage of all types of ships in

the world. The share of new (1–4 years) bulk carriers in the total number of ships on a global scale

in the years 2010–2016 was 29–46%.

The natural gas supply is used from Russia Federation as a political instrument in the geopolitical and territorial conflict with Ukraine. The effectiveness of Russian strategy towards Ukraine is due to the fact that power in Kiev is also exercised by the pro-Russian politicians and supported on the part of Ukrainian oligarchs. The two countries are interdependent in terms of energy by means of the existing gas infrastructure and long-term contracts, because Ukraine guarantees the Russian Federation the transit of natural gas to Europe through its system of transmission gas pipelines, and Russia pays for the transit and used to supply the agreed amount of gas to Ukraine. For the first time – in 2016 – Ukraine didn’t import natural gas directly from the Russia Federation. This article attempts to obtain an answer to the research question, whether Ukraine actually strives to diversify its natural gas supply. What part of this policy is the Ukrainian political instrument in terms of Russia, and what part is the real political objective? Especially in the context of the gas contract between both States, ending in 2019. What role will be played the underground gas storage in the geopolitical struggle? Despite Nord Stream II the Russian Federation still needs the Ukrainian pipelines to fulfill contractual obligations in gas supplies to Europe. What are the strategic goals of the energy policy of Ukraine and Russia? The geopolitical as well as geo-economic theories will be applied. Moreover, a factor analysis as well as a decision-making analysis will be used. The political analysis method and the forecasting technique are applied to obtain, not only theoretical, but also practical input.

The paper points out the role of terms in academic activity, particularly in onomastics. A survey of onomastic terms present in Polish dictionaries of linguistic terminology and onomastic encyclopaedias has been made. The need has been stressed to follow the rules of terminography in every dictionary of terms. Some normative terms, such as official name, dialectal name, minority name, have been suggested to be included as additional entries in glossaries of onomastic terms.

This paper presents the main dilemma of development of the Polish energy sector on the 20th anniversary of the first liberalization directive of the European Union, which created the energy market. The situation in the Polish energy sector based on fossil fuels, its transformation into lower emission one is closely connected to the process of restructuring and further development of the mining sector. On the other hand, we are witnessing the development of RES, household installations producing electricity with storage and the electrification of public transport. The investments in new, large scale fossil fuel fired power plants are very expensive and not economically proven when electricity prices are low. Until the new direction of investment in energy sector will be decided, the option of the lasting of the operating existing power units seems to be a good proposal. Is the thesis: “The energy security of Poland should be fully based on indigenous sources, generation and distribution assets, delivering electricity to end users. Ensuring competitive energy prices to the economy and households, the market should be fully open to producers and consumers, including chip electricity arising from the European single market” the right assumption for the Polish energy policy?

The article includes considerations and author’s proposals concerning the regional dimension of social policy. This aspect of social policy has not been investigated widely so far. The scope of regionalism and its forms are linked with the dominant social doctrine in a given country. They reflected in the ratio of territorial self-governments’ own incomes against those of the state budget, and in the institutional freedom they have in the area of benefit structuring, that is in decentralization. In the case of Poland, the political changes connected with the doctrinal ones hamper the development of regional social policy. This may have a negative impact on the coordination and implementation of social policy actions undertaken on different government levels and on the adjustment of social benefits to the needs of a region’s residents.

European Union competition policy is shaped rather differently in particular economic sectors. The best example of this is maritime transport. In recent years this area has found itself at the center of the European Commission's attention. Inter alia, this has been caused by breaches in the prohibition of abuse of a dominant position. This situation is a result of a lack earlier of appropriate legal instruments that could permit the application of Union regulations in this area. Only in 1986 was decree nr 4056/86 issued, which established detailed regulations for applying article 81 and 82 of the Treaty of Rome to maritime transport. Those cases examined buy the European Commission and the European Court of Justice largely concern the still unclear issue of joint domination. The majority of offences is committed by maritime transport conferences, which by operating in conjunction abuse their dominant position.

The Convention of the Law of the Sea of 1982 states clearly that countries bordering semi-enclosed seas, such as the Baltic, are expected to cooperate closely in securing their rights and executing their duties. The obligation to cooperate as stated in Article 123 of the convention refers to, among others, any installation or structure constructed on the Baltic Sea bottom. Russia and Germany both ignored this obligation as they viewed the proposed construction in strictly commercial terms. This position not only violates the norms of the both the Convention of the Law of the Sea of 1982 and HELCOM of 1992, but it also ignores the fundamental principles of the energy policy of the European Union. Article 23 statute 3 of legislation on the Republic of Poland's sea areas and marine administration, states that permission to construct and exploit any constructions within Polish sea areas (including those in the exclusive economic zone) is not to be granted if the proposed construction threatens the environment, marine resources, or the national economy. Unquestionably, the proposed Russian-German pipeline poses an ecological threat due to its length and is contrary to Polish interests.

In the nineteenth century a clause concerning civil liability was attached to insurance documents in maritime transport. Concretely, this confirmed the insurer's acceptance of three-quarters of the liability for any collision. The ship owner accepted one quarter of the liability. Ship owners, wishing to spread the material risk of damages connected with the collision of vessels, began to join together in so-called mutual insurance clubs. Thirteen of the largest mutual insurance clubs formed a society called the International Group of P and I Clubs. This insures and reinsures more than 90% of world tonnage (and almost 100% of the cargo of European tonnage). The author discusses the decision of the European Commission (1999/329/WE) which grants the International Group of P and I Clubs exemption from the prohibition of cartel collusion and from two agreements: the International Group Agreement and the International Pooling Agreement, to both o f which it exclusively applies. The first agreement limits competition between clubs and the possibility of bringing a ship owner insured in one club into another club by offering him a lower rate. The second agreement concerns the spreading o f the risk o f liability for claims among members of the Group.

Ensuring access to sustainable, affordable and clean energy sources is a top priority of the global energy agenda. It is reflected in the seventh goal of the UN Sustainable Development Agenda with the three dimensions of economic growth, social inclusion and environmental protection. The seventh goal is aimed at providing the sustainable development of energy systems whilst taking into account these dimensions. To assess the development trends of national energy systems within the framework of the global energy agenda, certain methods of quantitative measurement have acquired particular relevance. Approaches to assessing energy security mainly depend on the interpretation of the “energy security” concept. The main methods for the integrated assessment of the energy security of states are generally compiled by international organizations. An important indicator for the measurement of the sustainable development of energy systems is the Energy Trilemma Index, built within the framework of the “energy trilemma” concept. It allows quantifying the ability of states to ensure energy security, energy equity and environmental sustainability, taking into account the national context.
Special attention is paid to the analysis of the energy systems of Russia, Kazakhstan and Armenia through the Energy Trilemma Index 2022. The studied countries actively participate in the integration processes in the Eurasian and post-Soviet space. Thus, the analysis of the Energy Trilemma Index 2022 allows us to become acquainted with the main trends of the energy sector development in the Eurasian space, exploring the conjuncture of energy markets and their main challenges. The study of the energy systems of Russia, Kazakhstan and Armenia through the energy trilemma index enables the identification the methodological significance of the index for assessing the sustainable development of national energy systems. The practical relevance of the index in the formation of the state energy policy for the sustainable development of the energy systems has also been emphasized.

The aim of the study was to develop an assessment methodology for the temperature of the surface of the friction pair during the braking for mine hoists. During the braking process, the work of friction is transformed into heat at the level of friction surfaces, and in case high temperatures are reached, the friction coefficient is influenced negatively, thus the risk of braking failure exists. In the first part of the study we measured the temperature of the friction surfaces for a particular case of hoist in real braking conditions. In the second part of the study is presented a theoretical model for the calculation of the temperatures resulted in the braking process for the hoist equipped with shoe brakes. The theoretical model for calculation was simulated numerically for a particular case in real braking conditions. Based on the conclusions resulted after the study, a series of hypotheses and recommendations for adjusting the control of the process parameters have been given out, in order to avoid the excessive heating of the brakes of the hoists and, respectively, their improved safety, maintenance and availability.

The occurrence of gas confined in shales allows us to consider it as a component of the host rock. During drilling wells, the gas is released into the drilling fluid from finely ground gas-bearing rock particles. The amount of gas released can be determined on the basis of mud-gas logging; in addition, it is possible to determine the gas-content in shales expressed by the volume of gas released per mass unit of rock [m3/ton]. The gas content in the Ordovician and Silurian shales (Sasin formation and Jantar member respectively) in two selected wells in northern Poland was determined using this method. It has been found that clearly distinguishable, highly gas-bearing sections, which are separated by very poorly gas-bearing ones, can be determined in the well log. The increased gas content in shales can be observed in zones generally enriched in TOC. No direct correlation between TOC and gas-bearing capacity was found however, but the structure of TOC variability and the gas-bearing capacity described using variograms is identical. Correlations of the distinguished gas-bearing layers in the wells under consideration suggest a multi-lens or multi-layered reservoir model. The lack of natural boundaries in the shale gas reservoir means that they must be determined arbitrarily based on the assumed marginal gas-bearing capacity. In the case of several gas-bearing zones, numerous variants of interpretation are possible. In any case the low, best and high estimated resources may be evaluated, assigned to each borehole in the area with radii equal to the range of variogram of gas content in horizontal part of the well.

The world economy is constantly faced with crises that cause a significant negative impact. Each crisis poses new challenges to the economy and, on the one hand, inhibits economic growth, and on the other hand, can become a powerful stimulus for the development and rethinking of fundamental approaches to its construction. Conducting an analysis and establishing relationships between the economic situation and the state of the energy sector make it possible not only to predict the future but also to develop specific steps to prevent crises or reduce their negative impact. At the same time, establishing and evaluating the relationship between key economic and energy indicators, the main one of which is definitely the energy intensity of GDP, will provide an opportunity to understand how improving energy security will affect the economic situation in the country. The generalization of Ukraine’s experience in rebuilding and recovering the economy after the biggest crisis creates a basis for further research in the field of energy management, crisis management, economics, and the construction of investment policy. The reconstruction of Ukraine after the war has the potential to become the most significant stimulus for development and economic growth. During the crisis, it is very important to pay attention to the country’s energy security. In particular, it is necessary to ensure the diversification of energy resources, taking into account their rising cost. Energy markets are currently experiencing extreme volatility caused by geopolitical tensions, which requires additional attention in the development and implementation of strategic guidelines for sustainable economic recovery in Ukraine.

The article presents the reviewed and summarised research activities of the Polish research groups on gravimetry and gravity field modelling in the period of 2019–2022. It contains the results of absolute gravity surveys for the maintenance of the international gravity reference level in Poland and Europe, and for geodynamic research with an emphasis on metrological aspects. It also contains relative gravimetry issues as well as the results of marine gravity surveys in the southern Baltic Sea. Non-tidal gravity changes were extensively investigated. Long-term gravity variations were monitored at the Borowa Gora Geodetic-Geophysical Observatory and in a few other locations in Poland. The contribution of gravimetric records to seismic studies was investigated. Temporal variations of the gravity field from GRACE (Gravity Recovery and Climate Experiment) and GRACE-FO (GRACE Follow-On) data, in particular, deformations of the Earth’s surface as well as temporal variations of heights, total water storage and groundwater storage were investigated. Moreover, GRACE-based products and the performance of monthly Global Geopotential Models (GGMs) were a subject of research. GGMs developed in last years were evaluated. The research on developing new approaches in geoid modelling and their validation was conducted. New regional and local geoid models were determined for Poland and Ethiopia. The use of different techniques for estimating the absolute sea level at sites of the selected network in the Baltic Sea was investigated.

Statistical moments have been used in different applications as in shape analysis of object, pattern recognition, edge detection texture analysis etc. The idea is to use the moments as features of high level for surface matching. The essential goal of surface matching is to determine transformation parameters between two surfaces generated in TIN or DEM without identical points. Statistical moments are considered as features that are applied to solve that goal, One of the main problems with using statistical moments for surface matching and for other applications is a very expensive computation time. To overcome this difficulty many algorithms have already been proposed. New approach of efficient computation of inertial moments for surface matching is proposed in the paper. The approach is based on Green's theorem that allows for transforming double integral into a line integral. In the consequence computation time of inertial moments of a single TIN-model (triangle) is reduced by a factor 4 as compared with time consumed by the use of direct method of double integral. The direct computation using line integral, that does not involve any approximation, ensures preservation of the accuracy of computed moments.

Modelling quasigeoid with centimetre accuracy requires taking into account irregularities of topography in the vicinity of a gravity station. i.e. the terrain correction w surveyed gravity. Accuracy of determination of the terrain correction affects quality of quasi geoid model determined. It depends on the resolution and accuracy of terrain data that usually is provided in the form of a digital terrain model DTM. Investigations were conducted with the use of the Digital Terrain Elevation Data - DTED2 model developed for Poland according to the NATO-STANAG 3809 standard, as well as global models SRTM3 and SRTM30 (The Shuttle Radar Topography Mission). Also height data from the gravity database was considered. The prism method of determination of terrain corrections was applied in majority of numerical tests. Practical method for determining the optimum radius of the integration cap considering roughness of topography as well as required accuracy of terrain corrections was developed. The effect of vertical and horizontal uncertainty of a DTM as well as its resolution on the quality of the terrain corrections was investigated. The terrain corrections obtained using a prism method were also compared with the respective ones calculated using the FIT approach. The usefulness of the available topography data for precise terrain correction computation in Poland was discussed. The results of the investigations were used to determining the strategy of computation of the terrain corrections to point gravity data in the gravity database for Poland. The "2005" terrain correction set calculated for I 078 046 gravity stations contributes to the increase of precision of gravimetric quasigeoid models developed for Poland.

The relevance of the study is due to the fact that the influence of the Internet and media resources is growing and there is a tendency to develop virtual personalities that have little to do with reality and show the features of an antisocial person. In this regard, this article is aimed at identifying aspects and characteristics of a network personality that is influenced by modern media resources. The leading methods of studying this problem are methods of analysis, deduction and classification, which will help to recognize the most basic aspects of the figurative-visual transformation of a person on the Internet, show the results of the influence of social networks on a person and demonstrate the changes that a person is exposed to in the Internet space. The article reveals and substantiates the features and aspects that are distinctive for an individual in the Internet society, negative and positive characteristics of Internet users. The author substantiates the daily interactivity of social media. Also, the most relevant and influential forms of network interaction are shown and the frequency of their use is analysed. The materials of the article are of practical value for students, teenagers, youth, parents, future teachers who should know the aspect of the manifestation of personality transformation in the Internet space.

Applying frame semantics, usage-based construction grammar, and quantitative corpus-based methodology, this article seeks to explore the nature of the extraposed construction with past participles complemented by that-clauses. To this end, the author extracts the occurrences of the It BE V_en that-construction from the Corpus of Contemporary American English (COCA), determines its structural, semantic, distributional, and discourse-functional features, and identifies verbs that are strongly associated with the construction in question. The study meaningfully contributes to a growing body of research on it-extraposition by conducting a qualitative and quantitative analysis of one of its variants, a grammatical pattern with past participles that has not been hitherto investigated in much detail from a quantitative corpus- based perspective.

Use ofvarious wastes containing iron or aluminium in wastewater treatment can be considered as an alternative method to expensive and commercial reagents. These wastes can be recycled thanks to this method, which is important from an environmental point of view. Washings generated during ground water treatment arc rather useless but they are one of waste iron sources. The article demonstrates a description of two ground water treatment plants supplying the city of Koszalin with drinking water. On the basis ofdata from the last four years, a balance of the annual amount of iron sludge formed as a result of backwashing filter beds in both plants was performed. The amount of waste iron exceeds 10 Mg Fe-year. Research on waste iron usage to remove orthophosphates from a model solution and real sludge liquor from sludge digestion showed that iron sludge from washings can be efficiently used in wastewater treatment technology.

Owing to its high concentrations of nitrogen and phosphorus, the slurry from water hyacinth (Pontederia crassipes) biogas production cannot be discharged directly without further treatment. To achieve the target of water recycling, a new strategy of combining a Carrousel oxidation ditch with a water spinach wetland was developed in this study for the harmless treatment of Pontederia crassipes biogas slurry. First, the water quality characteristics of the biogas slurry were measured. Then, comprehensive tests of the combined slurry treatment system were carried out to verify pollutant removal performance and mechanism. The results showed that the Carrousel oxidation ditch reduced the inlet pollutant load of the subsequent water spinach wetland. The chemical oxygen demand (COD), and ammonium nitrogen (NH4+-N), total nitrogen (TN), and total phosphorus (TP) contents of the average effluent from the combined system were less than 50 mg/L, 1.6 mg/L, 6 mg/L, and 0.5 mg/L, respectively, which means that all met urban sewage treatment standard of Level 1 Grade A (GB18918-2002). Gas chromatography – mass spectrometry analysis showed that the combined system had decreased various types of organic pollutants in the biogas slurry exponentially, efficiently removing alkane pollutants, aromatic hydrocarbons, and heterocyclic compounds. Scanning electron microscopy images revealed very large surface area of the water spinach roots in the wetland, which played important roles in enriching the microorganisms and trapping organic matter. Plant absorption, microbial degradation, and filtration were the primary ways in which the water spinach wetland purified the biogas slurry.

The purpose of the study was to compare auditory judgments of sound clarity of music examples recorded in a concert hall with predictions of clarity made from the impulse response signal recorded in the same hall. Auditory judgments were made with the use of two methods: by rating sound clarity on a numerical scale with two endpoints, and by absolute magnitude estimation. Results obtained by both methods were then compared against the values of clarity indices, C80 and C50, determined from the impulse response of the concert hall, measured in places in which the microphone was located during recording of music examples. Results show that auditory judgments of sound clarity and predictions made from the C80 index yield a similar rank order of data, but the relation between the C80 scale and perceived sound clarity is nonlinear. The data also show that the values of C80 and C50 indices are in very close agreement.
