An overview of the existing literature on the quality of air pollution proves that the majority of research in this field, both in Poland and in the world, concerning particulate matter in atmospheric air, at workstations and less in residential buildings. Due to the above, the methodology in this area is widely available. The problem of particulate matter in sports facilities is decisively different and research conducted in this regards has been so far the subject of only a few publications. Therefore, there are no recommendations about the parameters which should be examined in sports facilities. This is a serious problem because the physical effort increases the frequency and depth of breath, making the PM particles reach more and deeper parts of the human respiratory tracts. Due to the lack of research in this area, this article presents review of methods for monitoring the physicochemical properties of air that are crucial for the health of sports facilities users.

‘His combination of feeling for style with historical knowledge is still a challenge to any editor of an historical text’ (Momigliano on Justus Lipsius). It is a far cry from the scholarly humanism of the sixteenth century to the complex specialism of modern scholarship, but the overlapping results of detailed research begin to call for integration or, at least, some attempt to define them in a wider context. This paper, therefore, proposes a combined exercise in the study of Roman historiography, ranging from the historian's choice of theme through its literary composition to the quality of its ultimate effect—to relate (so to speak)res, ars, ingenium. The subject is large, but the argument involves mainly precise treatment of evidence at the critical points.

The subject of the paper is conclusion and execution of direct contracts between consumers and utilities providers.The main aim of the paper is to confirm or disprove the hypothesis that direct contracts between consumers and utilities providers are more convenient for utilities providers than for consumers.The methodology of the study includes general scientific methods (analysis, synthesis, comparison, generalization, description) as well as particular academic legal methods (formal-legal analysis of theoretical and regulatory sources, interpretation of legal acts, judicial and arbitration practice).The main results and scope of their application. The current procedure for the provision and payment of utilities is based on the concept of "performer of utilities", which are the management organizations, homeowners' associations, housing cooperatives. The performer of utilities enters into a contract with utilities provider. These utilities are acquired by the contractor at the border of its operational responsibility (on the border of an apartment building), then this resource is already provided as a utility service to final users – tenants and owners of premises in an apartment building. Consumers pay for utility services to the contractor of utilities, and he, in turn, transfers the received payments to the utilities provider (resource supplying organization). Such a scheme of contractual relations leads to problems, including the following: the performers do not enter into contracts with the utilities providers (resource-supplying organizations), thereby trying to exclude their responsibility for the quality of services; do not pay fully or partially for the supplied utility resource. In this regard, the legislation has been amended to allow direct contracts between consumers of public services and resource organizations and, accordingly, directly pay for utilities.Conclusions. Direct contracts between consumers and utilities providers are more convenient for utilities providers than for consumers in the scope of responsibility for the poor quality of utilities.

The Mesozoic-Cenozoic coral Order Scleractinia has been suggested to have originated or evolved (1) by direct descent from the Paleozoic Order Rugosa or (2) by the development of a skeleton in members of one of the anemone groups that probably have existed throughout Phanerozoic time. In spite of much work on the subject, advocates of the direct descent hypothesis have failed to find convincing evidence of this relationship. Critical points are:(1) Rugosan septal insertion is serial; Scleractinian insertion is cyclic; no intermediate stages have been demonstrated. Apparent intermediates are Scleractinia having bilateral cyclic insertion or teratological Rugosa.(2) There is convincing evidence that the skeletons of many Rugosa were calcitic and none are known to be or to have been aragonitic. In contrast, the skeletons of all living Scleractinia are aragonitic and there is evidence that fossil Scleractinia were aragonitic also. The mineralogic difference is almost certainly due to intrinsic biologic factors.(3) No early Triassic corals of either group are known. This fact is not compelling (by itself) but is important in connection with points 1 and 2, because, given direct descent, both changes took place during this only stage in the history of the two groups in which there are no known corals.

This paper focuses on the understanding of service quality in the context of Vietnamese universities. It proposes an approach for measuring the quality of the higher education service provided by universities in Vietnam. Firstly, an exploratory study was conducted. Then, the set of items which were generated became the subject of a questionnaire that was then administered to 675 students of a Vietnamese university to determine the dimensions of higher education service quality in this context. The obtained results permit us to appropriate a measurement scale which is slightly different from the SERVQUAL scale widely known as the standard for measuring service quality. The results also show that tangible elements, responsiveness and assurance seem to be three specific dimensions of the higher education service of Vietnamese universities.

The recent reprinting of Álvaro de Silva’s 1998 edition of a selection of More’s letters prompts the author to examine the subject of Spanish translations of More, and of de Silva’s general commentary on More’s correspondence and on his relationship to other humanists. The author reflects on aspects of More’s personality as exposed in his letters and uses what he finds as a corrective to several biographical misconceptions. He points out the strengths and weaknesses of de Silva’s work and compares it with that of other translators, particularly Elizabeth Rogers, and notes the particularly Spanish quality of de Silva’s edition.

The aspiration to keep the synergy in relations between majorities and minorities repeatedly emerges as the cause of conflicts in social relations. It is also a subject of the interest of the multicultural education, particularly in countries of Eastern Europe, building contacts with the culturally and ethnically diverse groups to a wider scale. Relations in culturally, religiously and ethnic diverse societies, are becoming more and more related to the personal attitudes and a given policy. These issues acquire in the prison circumstances even greater significance, as given moods and personal attitudes of the prison staff create the pragmatic aspects of the professional activities addressed to the sentenced. Additionally, the key role is played by the quality of the penitentiary policy and the legal culture. The article presents the comparative analysis of the research carried out in 2016 amongst the prison staff in Poland. The subject of the research concerned attitudes that influence the decisive processes. The personal relations have been analyzed in the context of the relation with the sentenced Muslims. The aim of the research was not only to reveal the quality of the decisions concerning the sentenced Muslims, but also the sources of such decisions. The latter, in consequence, may shift, as the research results prove, towards synergy or discrimination. The diversification of the discrimination was one of the intriguing aspects, disclosed at various levels that not always explicitly concerned the discrimination of the minority.

There are investigated the influence of operating pressures in the gas supply system on the level of such energy indicators as efficiency, gas flow and gas overrun by gas equipment in residential buildings. There is established a relationship between the values of operating pressures in the gas supply system and the gas consumption level of household appliances. The causes of insufficient pressure in the gas networks of settlements are analyzed in the article. There is also developed an algorithm for calculating the change in the efficiency of gas appliances depending on the operational parameters of the gas network. It has been found that the most efficient operation of gas appliances is observed at an overpressure at the inlet of gas appliances of about 1200 Pa.To ensure the required quality of natural gas combustion among consumers and minimize gas consumption there are justified the following measures in the article: coordinating a domestic regulatory framework for assessing the quality of natural gas with international norms and standards; improving the preparation of gas coming from local wells before supplying it to gas distribution networks; auditing low pressure gas pipelines and reconstructing areas affected by corrosion; ensuring standard gas pressure in the network for the normal operation of domestic gas appliances; stating quality indicators of natural gas combustion by gas sales organizations.
