In 1949 the first book of the Atlas of Polish Traditional Costumes series appeared. Józef Gajek was the one who initiated the series, published by Polish Folk Association to this day. He was associated with Polish Ethnographic Atlas, which had a great impact on the character of the series. Its main objective was to describe Polish traditional costumes according to particular regions. Janusz Kamocki and Barbara Bazielich were subsequent editors of the series. Since 2011 the authors of this article have been part of the editorial staff. At their initiative ten more books of the series were published in the years 2013–2018, field research on traditional handicraft was conducted and the Traditional Costume Section was established. The article describes the circumstances accompanying this editorial series appearance and discusses both main directions in research on traditional costumes and activities for popularising knowledge of this unique cultural phenomenon.
Maintaining railway turnout operability is crucial for ensuring railway transport safety. Electric heating of railway turnouts is a significant technical and economic issue. The classical heating is characterised by high power consumption. For this reason, research is needed to optimise the current system. This paper presents results of a numerical analysis and of experimental researches. The numerical analysis was carried out using the ANSYS software. There was conducted a numerical comparative analysis of energy loss during heating performed using two different heaters. Including the classical method and a heater thermally insulated from a rail. In the first step, heating of a working space filled with a substitute snow model was considered. The snow-covered surface area was held within the working space of the turnout. It was assumed that the snow substitute material had thermal properties approximately the same as real light snow. It was also assumed that the material is in the solid state which would not undergo a phase change. In the next step, a real snow model that included the phase change process was taken into account. The energy efficiency and heat distribution in the turnout have been analysed and compared. The experimental researches were carried out in a physical model. The results showed that the use of a contactless heater results in creating a larger area over which emitted heat affected snow in the working space. Consequently, more snow was melted around the contactless heater than the classic one. This experimental observation supported the results of the numerical analyses presented previously.
