The constant increase in the popularity of renewable energy systems allows residential building users to apply solutions leading to the diversification of the energy supply. The use of RES systems in residential buildings not only contributes to a higher level of environmental care, but also significantly and measurably improves the energy efficiency of the facility. Using hybrid systems allows the supply to be reduced or eliminated from conventional energy sources. The article presents common layouts of renewable energy systems, which are successfully used in residential buildings. It also shows the impact of such systems on the amount of savings achieved in the use of energy from external or conventional sources. In residential buildings, the possibility of energy generation in the form of electricity and heat is dependent on many factors that determine the type and size of the systems used to obtain energy from renewable sources. We should assume the further and continuous development of RES, which will increase the share of electricity and heat produced in households. Technological development, decreasing prices of equipment and components used for the installation of green electricity generation systems will be a conducive factor for increasing the popularity of RES systems, not only for residential buildings but also for other types of buildings. The article also points out the economic aspect of the RES systems application. It presents the positive impact of RES installations on the environment and estimates the average time of financial reimbursement. The economic analysis concerns individual systems of renewable energy systems used in residential buildings.

The role and importance of energy security increases with the development of civilization, whose inherent element has become the demand for energy and its carriers. The article discusses the issue of cooperation in the field of energy security in Central Europe at the moment of finishing work on the North-South Corridor, which changes the existing gas architecture in the region. In order to better understand the situation in the region, the energy systems of the Visegrad Group countries, identical to the Central European region, have been analysed, according to the definition of the World Bank and OECD. Considering the historical and geopolitical connections of the Visegrad Group’s fate, it is important to create a common gas market. The physical interconnection of gas systems greatly increases energy security in this region. Moreover, thanks to the construction of LNG terminals in Poland and Croatia, it will be possible to diversify not only the routes, but also the sources of supply of this important raw material.

In this paper, selected aspects of energy efficiency are shown. The European Union regulations in area of energy efficiency such as Directive 2012/27/EU, are discussed. The national legal regulations which describe energy efficiency such as the Energy Efficiency Act are presented. Principles concerning the obligation of energy savings and energy audits of enterprises are described. National, regional and local programs and measures concerning the improvement of energy efficiency are performed. These are horizontal measures and energy efficiency measures in: industry, transport, the buildings of public institutions and energy generation and supplies. National economy energy efficiency is shown. The energy intensity indicators (primary, final) and rate of their changes in last years are performed. Moreover, directions of undertakings connected with the possible future reduction in energy intensity of the national economy, are defined. An analysis of energy efficiency measures and solutions for the improvement of energy efficiency, especially in industry and households, is performed. The improvement of economy energy intensity indicators constitutes the most effective solution which brings significant economic, technical and environmental benefits such as an increase in economic innovation and its competitiveness, the improvement of the energy supply security level, a reduction in the consumption of natural resources and a reduction of air pollution and greenhouse gas emissions. The conclusions contain an analysis of the present level of energy efficiency in Poland and the perspectives of its increase in the future along with the benefits connected with it.

Energy security is one of the most frequently analysed phenomena in the energy markets. Great variety of scientifc efforts should have indicated clear definition of the phenomenon. However, those studies highlighted more than 80 different definitions of what energy security really is. Due to the fact, that energy security is analyzed by different scientific disciplines, studies have provided a comperehensive reflection on the phenomenon.

The main objective of this paper is of the theoretical nature and focuses on showing energy security externalities. Author delivers an integrative review focusing on existing literature referring to the analyzed phenomena. Energy security is though studied only from the perspective of economics therefore interdisciplinary studies are out of the study scope. The reason for such scientific procedure stem from a belief that each discipline approach is different in terms of concepts, research methods and though results that are obtained. Therefore without undermining high value of interdisciplinary approaches to energy security, author decided to concentrate solely on economic perspective, which in energy security studies seems to be underestimated. Such approach in author’s belief helps achieve theoretical clarity of the below given analysis.

Presented paper is of the theoretical nature and focuses on showing energy security externalities. Critical literature review shows the literature mainstream in which energy security externalities are

The structural system of a multiple strip-shaped pillar-roof is common in underground mine exploitation, and research on its mechanics and micro/macroeconomics is meaningful for utilizing strip-shaped pillar resources. A general model of the structural system of a multiple strip-shaped pillar-roof was established, the deformation mechanism of the model was analysed by material mechanics, and the deflection curve equations of the model were obtained. Based on the stress strain constitutive relation of the strip pillar and cusp catastrophe theory, the nonlinear dynamic instability mechanism of the structural system of a multiple strip-shaped pillar-roof was analysed, and the expressions of the pillar width for maintaining the stability of different types of structural systems were derived. The benefits of different structural systems were calculated using micro/macroeconomic theory, the type of the structural system was determined, and different recovery schemes were obtained. Theoretical application research was applied to a large manganese mine, and the results demonstrate that no pillar recovery was needed in 2016, a 9-m wide artificial pillar could be built to replace a pillar in 2017, and the construction of 14-m wide artificial pillars can be conducted in 2018.

Emerging technologies represent the direction of the new industrial revolution of promoting sustainable economic and social development, and strategic emerging industries have developed rapidly in China. The development of these emerging technology industries requires more mineral resources as raw materials, especially the need for specific minerals, has increased. The unsatisfied growing demand for minerals used in emerging technologies or an unexpected supply disruption in major producing countries could have an impact on economic development. There are only several studies on the supply of mineral resources from the perspective of mineral resources needed by the development of China’s emerging industries. To assess the criticality of the minerals needed by the strategic emerging industries in China, this paper adopts three indicators: import concentration, the volatility of prices and the application requirements by the Chinese 13th five-year plan dedicated to strategic emerging industries in 2016. Furthermore, 34 types of nonfuel minerals and mineral raw materials are separated into three categories. Finally, this paper indicates that the three indexes are all high for 8 minerals with supply risks, application in emerging technologies, and substantial market fluctuations which need the support of special policies. Two indexes of three Level-II indicators are high for 14 minerals which need different policy combination measures, and one index is high for 12 minerals which also needs attention, all of which were analyzed.

Gravity Recovery and Climate Experiment (GRACE) mission data is widely used in various fields of science. GRACE explored changes of the gravity field regularly from April 2002 to June 2017. In the following research, we examine variance of signal contained in two different formats of GRACE data: standard spherical harmonics and mass concentration blocks (so-called “mascons”) solutions, both provided in the most recent releases. For spherical harmonics-based solution, we use monthly gravity field solutions provided up to degree and order (d/o) 96 by three different computing centers, i.e. the NASA’s Jet Propulsion Laboratory (JPL), the German Research Center for Geosciences (GFZ) and the Center for Space Research (CSR). For the mass concentration blocks, we use values of total water storage provided by the CSR, JPL and the Goddard Space Flight Center (GSFC) computing centers, which we convert to spherical harmonic coefficients up to d/o 96. We show that using the anisotropic DDK3 filter to smooth the north-south stripes present in total wate storage obtained from standard spherical harmonics solution leaves more information than common isotropic Gaussian filter. In the case of mascons, GSFC solution contains much more information than the CSR and JPL releases, relevant for corresponding d/o. Differences in variance of signal arise from different background models as well as various shape and size of mascons used during processing of GRACE observations.

In the morphosyntactic literature, there exist two approaches to the problem of argument structure in English nominal synthetic compounds such as furniture moving or dog training. According to Borer (2012), such synthetic compounds belong to the class of referential nominals and thus lack argument structure. On the other hand, Alexiadou (2017) maintains that the external argument is present in the structure of synthetic compounds due to their ability to co-occur with by-phrases. In this paper, we present an extensive set of corpus data to show that synthetic -ing compounds do project the external argument, which is evidenced by their ability to license not only by-phrases but also agent-oriented adjectives and instrumental phrases. Importantly, the corpus data indicates that certain synthetic -ing compounds display the capacity to occur in aspectual contexts; nominal compounds fall in two classes in that regard.

With a plethora of factors at work blurring the notoriously tenuous distinction between active and passive interpretations of verb constructions, one might with good reason express doubt as to whether establishing hard and fast principles for differentiating them is at all a sensible task. After a brief survey of passivum tantum -and basically passive verbs, as well as of chameleon-like, statal and dynamic passives, the author of the present contribution takes it upon herself to closer investigate the verbal or adjectival status exhibited by a series of -ed forms – as cited by various linguists (Stein, Quirk et al, Downing & Locke, Dixon) – with a view to advancing a more rigorous classifi cation of -ed for-ms based on the syntactico-semantic description of their individual behaviour in the various combinations analysed. The table submitted shows -ed forms located on an imaginary scale spanning passivehood from bona fide dynamic passives to copular complementation, with four further partitions in between. In the concluding section the author further glosses the subcategorization proposed, in that she provides the semantico-pragmatic motivation underlying the rather difficult choices made in the process.

The focus of the paper is the historical comparison of E fist and P pięść from the perspective of diachronic phonology. The paper specifically addresses the issue of the phonological development of this pair of cognates. The main aim is to explain the relatedness and differentiations of the modern reflexes of the original Proto-Indo-European roots and to account for their different phonological developments in both languages with a view to understanding the connection between the contemporary cognates. These aims are realised by means of searching for sound changes that explain the discrepancy in the phonological shapes of modern cognates and collecting other pairs of cognates that demonstrate the effect of theses sound changes. As the result of the historical and comparative analysis, it is argued that some of the Proto-Germanic reconstructions are more likely than others and in conclusion the most probable development of the two cognates is outlined in the chronological order. It is remarkable that the cognates of the compounds pięść / fist are to be found almost exclusively in Slavic and Germanic and the effect of their development resembles blending.
