ABSTRACT
The thermal decomposition of ethanethiol was studied using a 1 mm × 2 cm pulsed silicon carbide microtubular reactor, CH3CH2SH + Δ â Products. Unlike previous studies these experiments were able to identify the initial ethanethiol decomposition products. Ethanethiol was entrained in either an Ar or a He carrier gas, passed through a heated (300-1700 K) SiC microtubular reactor (roughly ≤100 µs residence time) and exited into a vacuum chamber. Within one reactor diameter the gas cools to less than 50 K rotationally, and all reactions cease. The resultant molecular beam was probed by photoionization mass spectroscopy and IR spectroscopy. Ethanethiol was found to undergo unimolecular decomposition by three pathways: CH3CH2SH â (1) CH3CH2 + SH, (2) CH3 + H2CâS, and (3) H2CâCH2 + H2S. The experimental findings are in good agreement with electronic structure calculations.
ABSTRACT
Self-management interventions are increasingly offered to people with chronic health conditions. However, there has been limited exploration of how applicable such an approach is in early stage dementia. In this study we explored the views of people with dementia and family caregivers on the use of self-management in dementia. We conducted semistructured interviews with 13 people with early stage dementia and 11 caregivers. We analyzed transcripts using thematic analysis. We found eight themes in the analysis, and they indicated that self-management occurs in the context of peoples' family and social relationships as well as relationships with professional services. Six of the themes involved barriers to and facilitators of self-management. It is evident from these findings that people with dementia and caregivers use self-management techniques. Their use of such techniques could be enhanced by the development of interventions designed to help people with dementia to develop their self-management skills.
