In the course of their working lifetime, dental technicians are exposed to numerous different dusts, some of which also contain toxic substances (Co-Cr alloys), which are employed in the so-called model casting. In order to establish the influence of the nature of the exposure associated with various dental technical procedures on pulmonary symptoms, 24588(More)
There is still a gap of reliable vapour pressure data at ambient temperature for low volatile organic substances due to the difficult and time-consuming determination using the classical methods. Static headspace extraction with a solid-phase microextraction (SPME) fibre in combination with gas chromatographic analysis provides an inexpensive tool for the(More)
UNLABELLED With the aid of a questionnaire survey conducted among 3,415 dental laboratories in Hesse and North Rhine Westphalia, the incidence of pulmonary symptoms among dental technicians, and their relationship to dust (exposure time: ET) was established. A total of 5,100 questionnaires were evaluable. The median age of the participants was 29 years, the(More)
The leachability of lindane from different biosolid amended soils was determined and compared to its bioavailability. Sand, soil, and a mixture of soil-sand (1:1 w/w) were spiked with lindane, blended with different amounts of biosolids, and subjected to a leaching process with water that lasted for 1-28 d. This procedure is in accordance with ISO/TS(More)
A Green's functions technique known to describe transport through a superconducting point contact with multiple Andreev reflection is merged with a rate equation scheme and thus extended to model transport through a series of two junctions enclosing an island between them. In the superconducting state such systems may show an interplay of multiple Andreev(More)
