Abstract

The main purpose of the study was an analysis of differences between Polish cities in the field of the quality of the environment. For this purpose the multi-dimensional analysis of correspondence on the basis of the developed complex matrix of markers was used. Due to a large number of variants of the analysed variables, the Ward’s method was applied. It allowed to establish connections between variants of variables. The value added of the research results presented in the paper is the approach to the evaluation of the environment quality in cities of Poland proposed by the authors. In this approach, apart from normally analysed variables directly describing the environment quality in the examined cities, the set of indicators related to the quality of the environment was used. According to the conducted studies, voivodeship cities in Poland are very differentiated in terms of the quality of the environment. It is related to the general social and economic development of cities, the level of industrialisation, the level of urbanization, etc. The development of cities requires not only the rational management of natural resources but also activities related to their protection.

Abstract

The main purpose of the study was a statistical analysis of of road safety in voivodeship cities of Poland. Spatio-temporal data contained, inter alia, in the Regional Data Bank and in the Police reports available on the Internet was used to conduct this study. In the study a zero unitarization method proposed by Kukula was used. This method allowed to characterize the cities in Poland according the traffic offences and indicate those of them which are distinguished by the best level of road traffic safety. In the analysis the number of traffic offences registered by the Police, the number of fatalities in road accidents and the detection rate of perpetrators of offences were included. The value added of considerations presented in this article is the analysis and evaluation of available statistical data on traffic crime as well as the use of multi-dimensional statistical analysis in the study regarding the determination of the road traffic safety level in voivodeship cities of the country. The taxonomic development measure based on the zero normalization applied in this paper enabled to order voivodeship cities in Poland by the level of traffic crime.

Abstract

Flexible inorganic solar cells are nowadays produced commercially on polymer and metal foils. Many technological enhancements are used to increase their conversion efficiency. In this paper authors focused on down conversion of ultraviolet and short wavelength visible light for improvement of amorphous silicon cells’ quantum efficiency. Towards this goal, rare-earth elements were applied as active particles in flexible polymer down converting layer. For practical experiments, screen-printing method, as the cheap, reliable and industrially-ready technology was used. Various materials composition as well as different layer thicknesses and morphology were tested in order to obtain optimal luminescent effect.
