In this work, the potential of magnetron sputtered magnesium uoride (MgF2) and MgF2 containing composite coatings for coloured solar collector glazing is investigated. Coloured thinlm interference coatings on the reverse side of the collector cover glass give solar collectors an aesthetic appearance, which facilitates their integration into the building’s envelope. Hereby, integration means tha...
A study on the in-vitro wear of the natural tooth structure by opposing zirconia or dental porcelain
PURPOSE This study was conducted to evaluate clinical validity of a zirconia full-coverage crown by comparing zirconia's wear capacity over antagonistic teeth with that of feldspathic dental porcelain. MATERIALS AND METHODS THE SUBJECT GROUPS WERE DIVIDED INTO THREE GROUPS: the polished feldspathic dental porcelain group (Group 1), the polished zirconia group (Group 2), and the polished zirco...
A thorough examination has been performed of the thermally induced stresses on a window in an enclosure-fire environment. Analytical and numerical methods establish the importance of bridling stress (due to axial elongation) and flexing stress (due to normal deformation). Most previous studies omitted the consideration of flexing stresses. Maximum stresses, being the sum of bridling and flexing...
Abstract The analysis is based on the results of computer simulation by using DesignBUILDER software. In multi dwelling house assessed. There are standard building constructions used like as brick wall with polystyrene thermal insulation, Windows plastic frame and double glazing flat roof insulation from without gravel layer. this considered so called green walls, that localized at eastern, sou...
Environmental factors are being increasingly taken into account in the increasing development of urbanization and citizen residential requirements. Climate and climate conditions are among the environmental factors that have always influenced human welfare. Climate has always been incorporated in old urban structures in Iran and can be easily observed. Despite the importance of climate-related ...
