• Informal employment in Poland: an empirical spatial analysis

  Publikacja

  • M. Beręsewicz
  • D. Nikulin

  - Spatial Economic Analysis - Rok 2018

  The main goal of our article is to bridge the gap in the regional analysis of informal employment in Poland and in particular to indicate the propensity for informal work in the working-age population, to test if informal activities are typical for marginalized people (less educated, unemployed, older) and to identify the regional and spatial heterogeneity in the propensity. We use data from the ‘Human Capital Balance 2010–2014’...

  Publikacja

  • M. Wasilczuk

  - ENGINEERING FAILURE ANALYSIS - Rok 2020

  This paper presents an analysis of the combined thrust radial bearing of a submarine propulsion shaft. The lubrication system of the bearing is based on a fixed ring. The efficiency of the lubrication system depends on the shaft speed and temperature, which affects oil viscosity. In turn, the thrust bearing load also depends on the rotational speed of the shaft, because as the speed increases, the drag of the ship increases simultaneously,...
