In contrast to low temperature superconductors (LTS), normal zone in HTS at low temperatures must develop over a much extended temperature range for current sharing with a highly non-linear dependence on temperature. The present work addresses this issue directly using both computer simulation and experimental studies. Several quench characteristics unique to HTS have identified using a comparative study of the underlying quasilinear parabolic equation represented in an appropriate dimensionless form for proper isolation of the known effects of temperature dependence of thermal properties. Most notable and counter-intuitive finding is that the minimum propagation zone (MPZ) was found to increase with transport current. The correlations of minimum quench energy (MQE) and the quench temperature of MPZ with operating temperature and current have been obtained for comparison with experimental results.

The results show that the cVMSs are the most abundant, detected in average concentrations that in some cases were as high as 170μgm(-3). Our study highlights the differences that can be observed between various indoor environments (e.g. domestic like bathrooms, bedrooms, or occupational) and between two countries. In most cases, the concentrations found in the UK are higher than in the respective indoor environments in Italy. The assessment of exposure to these two countries for adults and children revealed significant differences both not only in the levels of exposure, but also in the patterns. In Italy, the biggest part of the exposure to VMSs takes place domestically, whereas in the UK, it is observed for occupational environments. Additionally, the compound specific isotopic analysis was employed as a source identification technique. The results are promising mainly for D5 that occurs in higher concentrations, but not for the less abundant lVMSs and cVMSs.
