This paper is aimed at presentation and analysis of different approaches to the phenomenon of "feeling for language". The purpose is to demonstrate that this term, although controversial, is of great importance in language acquisition and in the evaluation of language expressions. The topic is discussed in the article with the help of definitions from Kainz, Knobloch, Lewandowski, Juhász, Olt/Disselkamp, and Trad. In the definitions, various facets of language feeling are taken up, such as its relation to intuition, reference to mother tongue and foreign language and individual or collective implications.
The paper presents the author’s reflection regarding the recent transformations of the city of Krakow. The study is focused on the changes that are novelties or distinctive to the city. The conclusions indicate activities that should be treated by city authorities as challenges for the public management of the metropolitan scale.
The paper presents research on dynamics, modeling and the results of experimental tests of the rotor system rotating in gas lubricated bearing with a floating bush. The dependence of rotor vibration intensity on the waviness of bearing elements was tested and simulated. It was confirmed experimentally that the amplitude of rotor vibration in gas lubricated bearing with double gas film is basically lower than the one with single gas film. The kinetic orbits of the rotor shaft vibration displacements are presented. Dynamic and mathematical models constructed enable to design bearings that distinct optimal according to the minimal vibration intensity.
