tba Peter Fankhauser (Institut für Deutsche Sprache, Mannheim), Visual correlation for exploring paradigmatic language change Abstract: Paradigmatic language change occurs when paradigmatically related words with similar usage context rise or fall together. We introduce an approach to explore such paradigmatic change in diachronic corpora by visually correlating two factors: Frequency change an...

The objective of this in vitro study was to assess the color change of resin nanocomposites exposed to a cola beverage at different times. Seventy-five cylinders (10 mm x 2 mm) were prepared from each of 4 resin-based composite materials, 3 nanocomposites (Filtek Supreme, Tetric EvoCeram, Premise) and 1 microhybrid (Filtek Z250), to give a total of 300 specimens. Specimens in each group were di...

Indicator cotton swabs have been developed in order to enable faster, less expensive, and simpler information gathering of a wound status. Swabs are normally used for cleaning the wound, but here, they were covalently functionalized with indicator chemistry. Thus, they in principle enable simultaneous wound cleaning and wound pH detection. Using an indicator dye with a color change from yellow ...
