This article is focused on an experimental measurement of settlement of blown insulation from crushed straw. Straw has appeared like building material in recent years. It is ecological and cheap building material which is required for sustainable construction. Straw is usually used in form of bales. These are generally used like thermal insulation filling the supporting structure. An alternative to straw bales can be crushed straw. Crushed straw is not used in building industry currently. Its thermal insulating properties and structure are appropriate to use it like blown or loose thermal insulation. The experimental measurement was necessary to verify application of crushed straw by blowing or bulk and to find out values of settlement. Results of this measurement are described in this article.
Przedmiotem artykułu jest określenie mobilności pierwiastków ryzyka w próbkach gleby termicznie aktywnego składowiska, będącegoefektem działalności górniczych w regionie Ostrawy. Próbki zostały pobrane ze składowiska Hedvika w okresie 2017–2018. Ekstrakcjaprób gleby została wykonana za pomocą trzystopniowej ekstrakcji sekwencyjnej BCR (Bureau Community of Reference). Ekstrakcjasekwencyjna daje informacje na temat procesów, które normalnie mają miejsce w środowisku. Składnik stały gleby jest stopniowo wypłukiwany w różnych odczynnikach ekstrakcyjnych, począwszy od najsłabszego aż do najsilniejszego. To dostarcza danych na tematogólnej ilości pierwiastków ryzyka obecnych w określonych warunkach środowiskowych. Wybrane pierwiastki ryzyka (Cr, Cu, Ni, Zn)zostały określone za pomocą metody ICP – MS (Inductively plasma mass spectrometry) oraz AAS (atomic absorption spectrometry)(Zn). Wypłukiwanie kwasu azotowego zostało zastosowane aby uzupełnić ogólną analizę ekstrakcji BCR.
The course of temperatures in the construction is one of the main indicators of well-designed and implemented wooden buildings. And improper design may cause the penetration of cold outside air into the structure which may negatively affect the whole construction of wooden house. This article focuses on selected construction of three wooden buildings which were carried out the in situ measurements. The resulting values are then compared and evaluated in terms of impact on the construction of wooden house. Mentioned are also possible and potential repairs and preventive measures.
In this article we assess the impact of water flow system and precipitation on choose hydro chemical parameter in water-bearing subside areas. Key findings of this study are significant correlation coefficient values obtained from the precipitation amount and occurrence of total phosphorus and phosphates. Therefore the significant effect of other anthropogenic activities on water reservoirs was excluded. The conclusion of this study is that inflowing water (in the case of relatively clean streams) and precipitation can have a positive influence on hydrochemical parameters in water-bearing subside areas and generally contribute to dilution.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
