The article describes the idea of a compact city, due to the needs and capabilities of contemporary Polish cities, with an emphasis on the Silesia region. Special attention has been paid to the possibility of increasing the cities’ density and several examples have been shown to present the possibilities of densifying the cities with new housing investments. Also, the article presents the studies that indicate the capacity for the internal development of selected Silesian cities: Katowice and Gliwice. The article ends with the recommendations for cities to become more compact.

The concept of control over electronic transferable records is the central premise of the UNCITRAL Model Law on Transferable Electronic Records. It indicates the method of determining the party who has the rights embodied in the negotiable electronic record. The purpose of this article is to present the most important issues related to documents and instruments that have a circular function in international maritime trade, and the intention to create a legal framework for them when they take the form of electronic records.

The location, geological structure and characteristics of the Kamionki Anticline is presented in terms of possibility of underground CO2 storage. It is situated in the Płock Trough, in the SW part of the Płońsk Block, and represents a synsedimentary graben originated in the Early and Middle Jurassic. It has been explored by a semi-detailed reflection seismic survey and three deep boreholes (Kamionki 1, Kamionki 2 and Kamionki IG-3). Assuming that the anticline is conventionally outlined by a contour line of the top of the Lower Jurassic, its length is about 15 km, width is about 5 km and the area reaches approximately 75 km2. Geological, seismic and reservoir property data allow concluding that this structure is suitable for underground carbon dioxide storage. The primary reservoir level for underground CO2 storage is represented by Barremianmiddle Albian deposits of the Mogilno Formation with an average thickness of 170 metres, containing on the average 85% of sandstones, and showing porosity of about 20% and permeability above 100 mD up to 2000 mD. The sealing series is composed of Upper Cretaceous marls, limestones and chalk reaching the thickness of about 1000 metres. The secondary reservoir level is represented by upper Toarcian deposits of the Borucice Formation.

This paper concerns an approach to model the ledger-stand joints of modular scaffolds. Based on the analysis of the working range of the ledger (represented by a linear relationship between load and displacement), two models of the ledger-stand joint are analysed: first – with flexibility joints and second – with rigid joints and with a transition part of lower stiffness. Parameters are selected based on displacement measurements and numerical analyses of joints, then they are verified. On the basis of performed research, it can be stated that both methods of joint modelling recommended in this paper, can be applied in engineering practices.

The article is devoted to the development of Polish sociology from the 19th century until the period of the Second Republic, when sociology became an established academic field. The first Polish sociologists studied sociology at various European universities, but later worked in different professions i.e., Supinski was an owner of a textile weaving shop, Krupinski was a priest and a teacher, while Limanowski, Świetochowski and Krzywicki worked as journalists. Their sociological interest was secondary to their professional life. What is interesting is that they first joined European sociological institutions as members of the Institut international de sociologie (The International Institute of Sociology), gave papers at international Sociological congresses and only much later spoke at Polish conferences. They published in „Annee sociologique” and „Revue international de sociologie.” At times they also taught at different European universities, for example Gumplowicz taught at the University of Grazu and Petrazycki in the St. Petersurg University. The first sociology programs were established in Poland after it regained its independence: in 1920 Leon Petrazycki was appointed chair of sociology at the University of Warsaw and Ludwik Krzywicki was appointed chair of a program called the history of socio-political systems. Sociology was treated then as an auxiliary academic field for the study of law. Sociology as an autonomous field was first created in Poznan and its main inspirer was Florian Znaniecki. Not until the second decade of the Second Republic was sociology established as a separate department at the universities in Kraków and Warsaw. At the wake of the WWII sociology was a well established academic field in Poland with its own programs of study, research intstitutes, scholarly journals and a professional association of practitioners.
