About 55% of over 14 million Polish households live in multi-family buildings. Cooperative or housing association buildings have a large share in this group. The heat is supplied from the district heating network or from local sources. With respect to facilities fed from gas boiler rooms, the signing and execution of fuel supply contracts is required. From October 1, 2017, the obligation to submit tariffs for gas trading set for all final customers (except for individual gas consumers in households) for approval to the President of the Energy Regulatory Office was lifted. Decisions regarding the choice of the supplier and the content of the concluded contract are made by the authorized bodies of the cooperative or housing association. The consequences of such decisions are borne by the owners and users of residential premises. Ensuring the continuity of a contract for the supply of gaseous fuel essentially comes down to establishing prices and rates in force for a given period. The right decision on the moment of signing the contract or the amendment, termination of the existing contract and signing a new one, or negotiation efficiency will result in financial profits for all users. The costs of heating and domestic hot water preparation are a significant component of the overall cost of the maintenance of flats in Poland. Therefore, it is even more important that the prices and rates agreed upon with the gas supplier are as favorable as possible to users. The high costs of heat are not only expenses for apartment owners. The attractiveness of flat on the rental market is also decreasing. The business activity carried out in facilities located in such buildings is also less competitive.
The authors of the article analyzed gas prices on the Polish market over the last 3 years and presented the results of simulations of the effects of specific prices and rates set in the contract for the supply of fuel at the cost of heating from the point of view of a single apartment. As these are not large amounts per year, they do not motivate to optimize the terms of the gas purchase contract in this respect. The dynamics of changes in gas prices in Poland, although slightly different from world trends, is high. This makes it difficult for those responsible to make the decisions, and for residential users, it often means spending differences in subsequent years. One of the consequences of setting prices and rates significantly higher than obtainable may also be the reluctance of local communities to take measures to increase the energy efficiency of the heat supply system. From the point of view of heating costs, such decisions may distort the economic effect of thermo-modernization.
The article discusses issues related to the generation, use, and transboundary movement of waste labeled with the code 191210 according to the waste catalogue regardless of its origin (municipal, industrial or mixed). Data contained in voivodship reports related to waste management and information about transboundary shipments shared by the Chief Inspectorate of Environmental Protection were also used in the article. The imbalance in the amount of produced and energetically used alternative fuels in Poland in the years 2015 to 2017 has been confirmed. This affects the economy of the waste management sector involved in the production of alternative fuels. The oversupply causes the prices of alternative fuels to fall and increases the need for subsidies in the case of the recovery or disposal of alternative fuels of lower quality. In the near future one should expect a stabilization of the supply of combustible waste to the cement industry, which is now beginning to achieve its technological potential; this is due to a high degree of replacement of fossil fuels. One should also expect an increase in the demand for alternative fuels from the commercial power sector and heating sector. It has been shown that much more alternative fuel is imported than exported from Poland. The amount of imported alternative fuel in the market is relatively low compared to the amount of fuel produced in the country. This oversupply affects, although not significantly, the possibility of using domestic waste for energy recovery. The export of the alternative fuel produced in the country is a favorable phenomenon when there is no possibility of sale on the domestic market. It seems rational, especially in the case of exports from installations producing fuels in border provinces.
The purpose of the present article is a contrastive analysis of the verbs and verbal forms expressing the spatial situation in the Pericope Adulterae from the point of view of their translations into Polish and French starting from the original Greek biblical text. The author presents the general context of the pericope, its controversial place in the Gospel of John as well as its construction and its linguistic specificities. Starting from the original text of this biblical passage, then are listed the Greek verbs which express a spatial situation and are subjected to the analysis from the point of view of their forms and their meaning. According to the Polish and French translations chosen from this evangelical episode, the author proceeds to the comparison of the proposed equivalents and presents the comments which ensue. The analysis of translations demonstrates that some of the equivalents are analogous for two or all of the three languages, and some are typical only to one of the three languages.
The main topic of this paper deals with a general description of the notion of the class of objects, its historical draft and development in linguistic studies (generative grammar of N. Chomsky, semantic markers in the theory of J.J. Katz, J.A. Fodor, the predicate-argument structure of S. Karolak and the electronic dictionary of G. Gross). The author takes advantage of this concept in her analysis basing on object-oriented approach and the disambiguation by W. Banyś. This article demonstrates also that the disambiguation of the meaning of polysemic word pass by a correct choise of a class of objects which is the only solution to provide adequate equivalents in the target language and the condition of the effective and satisfying translation supported by computer.
The article discusses the importance of the context in the process of automatic translation. The author focuses on two major issues: the lexical database provided by the traditional dictionnaries combined with the data resulting from the analysis based on the object-oriented approach proposed by W. Banyś. A more detailed characterization of the classes of objects around the analysed verb may have the influence on sometimes very subtle differences in the translation. The conclusion is that all this kind of data and the approach adopted in the process of the disambiguation of words are useful to find adequate equivalents in the target language, which the author tries to demonstrate on the example of the French verb descendre. Automatic translation can also show that the modular structure of the approach proposed to the description of words is very specific and doesn’t allow to many possible translations of the word’s concrete use.
International scales describing the intensity of tornadoes are investigated along with reports from the Polish Government Security Centre on all types of wind storms in Poland. Then, collected tornado reports for the years 1899–2019 in Poland, a set of the annual maximum gust wind speeds measured at 39 meteorological stations from 1971 to 2005 (35 years), descriptions of Poland’s strongest wind storms in the 21st century, estimating the risk of significant strong and extreme winds in Poland, and classification of maximum wind speeds by Lorenc (2012) are presented. Based on these data, i.e. measured and estimated wind speeds, this paper proposes two separate intensity scales to categorize synoptic, thunderstorm, and downslope winds (in the Tatra and Karkonosze regions), derechos, tornadoes, and downbursts, i.e. all types of wind storms. These scales are simpler than the one put forward by Lorenc (2012). These two scales cover a range of maximum wind speeds from 20 to 90 m/s. This proposal is only applicable to Poland. Other countries may determine whether it applies to them.
The aim of the paper is to formulate physically well founded yield condition for initially anisotropic solids revealing the asymmetry of elastic range. The initial anisotropy occurs in material primarily due to thermo-mechanical pre-processing and plastic deformation during the manufacturing processes. Therefore, materials in the “as-received” state become usually anisotropic. After short account of the known limit criteria for anisotropic solids and discussion of mathematical preliminaries the energy-based criterion for orthotropic materials was formulated and confronted with experimental data and numerical predictions of other theories. Finally, possible simplifications are discussed and certain model of isotropic material with yield condition accounting for a correction of shear strength due to initial anisotropy is presented. The experimental verification is provided and the comparison with existing approach based on the transformed-tensor method is discussed.
At the end of 2018, when the Hučivá Cave (Hučivá diera, Rausch Keller) was explored in Tatranská Lomnica, profile deposits in rear areas of the cave were found disturbed by an amateur excavation. One stone artefact was first found in back-dirt clay-layer material at the excavation pit, later joined by four more specimens from the cleaned pit profile. The Typological analysis of the artefacts shows, that their closest parallels are found in inventories of the Magdalenian culture. Hučivá is the only cave in the whole Tatras with documented prehistoric settlement and the only Slovak cave with evidence of the Magdalenian culture. The discovery provides new information concerning subsistence strategies of late Pleistocene hunters in High Tatra Mountain landscapes. In light of this discovery, the possibility of seasonal movements along the northern slopes of this mountains range to the east and then south, through the mountain passes to the upper Spiš region should now be considered.
Research on automatic translation has recently become a very popular field of study for linguists. The process of adjusting data collected from language to meet the machine’s potential and efficiency requires the knowledge and use of an accurate and effective methodology. The linguist’s task is not only to feed data collected from traditional language dictionaries into the computer’s memory, but it is also necessary to take into consideration all the relations that hold among the elements being described, as the aim of automatic translation is to enable the system to carry out an accurate and effective translation of texts. The paper is also an attempt to show how the object oriented approach proposed by W. Banyś resolves the problem of polysemy of words in a natural language which is one of the major problems in computer assisted translation. For the computer assisted translation to be exhaustive and effective, a process of disambiguation of a polysemous word should be carried out thus enabling a correct generation of its equivalents in a target language, which is presented on the basis of the English causative verb open.
