The main purpose of this article is to present how geographical names (microtoponyms) acquire slang names. The site of inquiry is the area of Wręczyca Wielka, which contains the names of different physiographic objects, e. g. fields, meadows, forests, paths. The data was collected from 2011 to 2015 during the informal utterances of the oldest and middle generations of the inhabitants of the area. The analysis also contains the justifications for the microtoponyms. The linguistic material was collected in the area near Kłobuck in the north of the Silesian Province. The first part of this article is devoted to the main transformation of the Polish rural areas after 1945. The latter parts of the text present e.g. the fact that microtoponyms sustain phonetic slang features which do not exist in contemporary slang, and the fact that geographical names are one of the elements of folk culture, as well as the link between the former and contemporary folk image.
Dust generated at an electric arc furnace during steel production industry is still not a solved problem. Electric arc furnace dust (EAF) is a hazardous solid waste. Sintering of well-prepared briquetted mixtures in a shaft furnace is one of possible methods of EAFD utilisation. Simultaneously some metal oxides from exhaust gases can be separated. In this way, various metals are obtained, particularly zinc is recovered. As a result, zinc-free briquettes are received with high iron content which can be used in the steelmaking process. The purpose of the research was selecting the appropriate chemical composition of briquettes of the required strength and coke content necessary for the reduction of zinc oxide in a shaft furnace. Based on the results of the research the composition of the briquettes was selected. The best binder hydrated lime and sugar molasses and the range of proper moisture of mixture to receive briquettes of high mechanical strength were also chosen and tested. Additionally, in order to determine the thermal stability for the selected mixtures for briquetting thermal analysis was performed. A technological line of briquetting was developed to apply in a steelworks.
The present investigation is concerned with the reflection in thermo-microstretch elastic solid in the presence of a transverse magnetic field, at the boundary surface. The generalized theories of thermoelasticity developed by Lord and Shulman (L-S) and Green and Lindsay (G-L) theories have been used to investigate the problem. The variations of amplitude ratios with angle of incidence have been shown graphically. It is noticed that the amplitude ratios of the reflected waves are affected by magnetic field, stretch and thermal properties of the medium.
