Reconstructing past media ecologies: The 1960s generation in Sweden

This article examines how an analysis of a broader media ecology of a particular generation can offer a more complex account of past audience habits than the ones we gain from quantitative audience ratings based on one medium alone. It also shows how past surveys can be put to use anew within new theoretical frameworks. The main argument is based on a cultural studies–inspired interpretation of a home electronics survey, conducted by the Swedish public service radio’s research unit in 1985. The main focus is on members of the cohort born during the 1960s, who grew up with television and quickly became avid television users. The longitudinal analysis of television preferences within the broader media ecology of this generation sheds new light on the relationships between different media, but also on the long-term impact that a particular media ecology may have on one’s engagement with the media at later stages of life

Studies on plasma-sprayed thermal barrier coatings

The emphasis of this work has been the fundamental characterization of the material properties of thermal barrier coatings. Tests have been carried out on plasma sprayed ZrO//2-8wt%Y//2O//3 and ZrO//2-12wt%Y//2//3 (YSZ) coatings. The thermal expansion coefficient ( alpha ) is anisotropic in the longitudinal direction (planar to the substrate) compared to the transverse orientation (perpendicular to the substrate). The magnitude of alpha is dependent on prior heat treatment of the coating. The coating, deposited onto a superalloy substrate, was thermally cycled to 1200 degree C and failure followed via acoustic emission (AE) techniques. AE count rate distribution varies with temperature. Relationships of this nature lead to an understanding of cracking mechanisms within the coating
