The subject presented in this paper refers to measurements and assessment of the corrected sound pressure level values (noise) occurring around a medium-power transformer. The paper presents the values of noise accompanying the operation of the power object before and after its modernization, which consisted in repeated core pressing and replacement of the cooling system. The main aim of the research work was the assessment of the influence of the repair work on the noise level emitted into the environment.

The paper presents phytosociological and hydrological results of field investigations carried out in old excavation in Mikołów - Gniotek town (the Silesian Upland) in June 2002. Owing to renunciation of building works, primary succession led to form riparian black alder forest Fraxino-Alnetum W. Mat. 1952 of anthropogenic origin. Vegetation of the area is mostly determined by water conditions indepentently of occurrence of sandy and silty clays in the soil.

The authors draw on their experience and past mountain landscape studies to describe an emerging collaborative research project designed to conduct advanced field studies and generate (and test) archaeological landscape models of past hunter-gatherer populations as well as pastoralist and early farming community seasonal transhumance migrations between lowland river valleys of Poland’s Podhale Basin and high altitude forests and meadows its adjacent High Tatra Mountains.

Isolated internal iliac artery aneurysms are rarely described in the available literature.
